To save space, busybox can be configured with only the -set of applets needed for each environment. The minimal configuration, with -all applets disabled, produces a 4k executable. (It's useless, but very small.) - -The manual configurator "make menuconfig" modifies the existing configuration. -(For systems without ncurses, try "make config" instead.) The two most -interesting starting configurations are "make allnoconfig" (to start with -everything disabled and add just what you need), and "make defconfig" (to -start with everything enabled and remove what you don't need). If menuconfig -is run without an existing configuration, make defconfig will run first to -create a known starting point. - -Other starting configurations (mostly used for testing purposes) include -"make allbareconfig" (enables all applets but disables all optional features), -"make allyesconfig" (enables absolutely everything including debug features), -and "make randconfig" (produce a random configuration). The configs/ directory -contains a number of additional configuration files ending in _defconfig which -are useful in specific cases. "make help" will list them. - -Configuring BusyBox produces a file ".config", which can be saved for future -use. Run "make oldconfig" to bring a .config file from an older version of -busybox up to date. - -Installing Busybox: -=================== - -Busybox is a single executable that can behave like many different commands, -and BusyBox uses the name it was invoked under to determine the desired -behavior. (Try "mv busybox ls" and then "./ls -l".) - -Installing busybox consists of creating symlinks (or hardlinks) to the busybox -binary for each applet enabled in busybox, and making sure these symlinks are -in the shell's command $PATH. Running "make install" creates these symlinks, -or "make install-hardlinks" creates hardlinks instead (useful on systems with -a limited number of inodes). This install process uses the file -"busybox.links" (created by make), which contains the list of enabled applets -and the path at which to install them. - -Installing links to busybox is not always necessary. The special applet name -"busybox" (or with any optional suffix, such as "busybox-static") uses the -first argument to determine which applet to behave as, for example -"./busybox cat LICENSE". (Running the busybox applet with no arguments gives -a list of all enabled applets.) The standalone shell can also call busybox -applets without links to busybox under other names in the filesystem. You can -also configure a standalone install capability into the busybox base applet, -and then install such links at runtime with one of "busybox --install" (for -hardlinks) or "busybox --install -s" (for symlinks). - -If you enabled the busybox shared library feature (libbusybox.so) and want -to run tests without installing, set your LD_LIBRARY_PATH accordingly when -running the executable: - - LD_LIBRARY_PATH=`pwd` ./busybox - -Building out-of-tree: -===================== - -By default, the BusyBox build puts its temporary files in the source tree. -Building from a read-only source tree, or building multiple configurations from -the same source directory, requires the ability to put the temporary files -somewhere else. - -To build out of tree, cd to an empty directory and configure busybox from there: - - make KBUILD_SRC=/path/to/source -f /path/to/source/Makefile defconfig - make - make install - -Alternately, use the O=$BUILDPATH option (with an absolute path) during the -configuration step, as in: - - make O=/some/empty/directory allyesconfig - cd /some/empty/directory - make - make CONFIG_PREFIX=. install - -More Information: -================= - -Se also the busybox FAQ, under the questions "How can I get started using -BusyBox" and "How do I build a BusyBox-based system?"

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It provides minimalist replacements for most of the - utilities you usually find in bzip2, coreutils, dhcp, diffutils, e2fsprogs, - file, findutils, gawk, grep, inetutils, less, modutils, net-tools, procps, - sed, shadow, sysklogd, sysvinit, tar, util-linux, and vim. The utilities - in BusyBox often have fewer options than their full-featured cousins; - however, the options that are included provide the expected functionality - and behave very much like their larger counterparts. - - BusyBox has been written with size-optimization and limited resources in - mind, both to produce small binaries and to reduce run-time memory usage. - Busybox is also extremely modular so you can easily include or exclude - commands (or features) at compile time. This makes it easy to customize - embedded systems; to create a working system, just add /dev, /etc, and a - Linux kernel. Busybox (usually together with uClibc) has also been used as - a component of "thin client" desktop systems, live-CD distributions, rescue - disks, installers, and so on. - - BusyBox provides a fairly complete POSIX environment for any small system, - both embedded environments and more full featured systems concerned about - space. Busybox is slowly working towards implementing the full Single Unix - Specification V3 (http://www.opengroup.org/onlinepubs/009695399/), but isn't - there yet (and for size reasons will probably support at most UTF-8 for - internationalization). We are also interested in passing the Linux Test - Project (http://ltp.sourceforge.net). - ----------------- - -Using busybox: - - BusyBox is extremely configurable. This allows you to include only the - components and options you need, thereby reducing binary size. Run 'make - config' or 'make menuconfig' to select the functionality that you wish to - enable. (See 'make help' for more commands.) - - The behavior of busybox is determined by the name it's called under: as - "cp" it behaves like cp, as "sed" it behaves like sed, and so on. Called - as "busybox" it takes the second argument as the name of the applet to - run (I.E. "./busybox ls -l /proc"). - - The "standalone shell" mode is an easy way to try out busybox; this is a - command shell that calls the built-in applets without needing them to be - installed in the path. (Note that this requires /proc to be mounted, if - testing from a boot floppy or in a chroot environment.) - - The build automatically generates a file "busybox.links", which is used by - 'make install' to create symlinks to the BusyBox binary for all compiled in - commands. This uses the CONFIG_PREFIX environment variable to specify - where to install, and installs hardlinks or symlinks depending - on the configuration preferences. (You can also manually run - the install script at "applets/install.sh"). - ----------------- - -Downloading the current source code: - - Source for the latest released version, as well as daily snapshots, can always - be downloaded from - - http://busybox.net/downloads/ - - You can browse the up to the minute source code and change history online. - - http://git.busybox.net/busybox/ - - Anonymous GIT access is available. For instructions, check out: - - http://www.busybox.net/source.html - - For those that are actively contributing and would like to check files in, - see: - - http://busybox.net/developer.html - - The developers also have a bug and patch tracking system - (https://bugs.busybox.net) although posting a bug/patch to the mailing list - is generally a faster way of getting it fixed, and the complete archive of - what happened is the git changelog. - - Note: if you want to compile busybox in a busybox environment you must - select CONFIG_DESKTOP. - ----------------- - -Getting help: - - when you find you need help, you can check out the busybox mailing list - archives at http://busybox.net/lists/busybox/ or even join - the mailing list if you are interested. - ----------------- - -Bugs: - - if you find bugs, please submit a detailed bug report to the busybox mailing - list at busybox@busybox.net. a well-written bug report should include a - transcript of a shell session that demonstrates the bad behavior and enables - anyone else to duplicate the bug on their own machine. the following is such - an example: - - to: busybox@busybox.net - from: diligent@testing.linux.org - subject: /bin/date doesn't work - - package: busybox - version: 1.00 - - when i execute busybox 'date' it produces unexpected results. - with gnu date i get the following output: - - $ date - fri oct 8 14:19:41 mdt 2004 - - but when i use busybox date i get this instead: - - $ date - illegal instruction - - i am using debian unstable, kernel version 2.4.25-vrs2 on a netwinder, - and the latest uclibc from cvs. - - -diligent - - note the careful description and use of examples showing not only what - busybox does, but also a counter example showing what an equivalent app - does (or pointing to the text of a relevant standard). Bug reports lacking - such detail may never be fixed... Thanks for understanding. - ----------------- - -Portability: - - Busybox is developed and tested on Linux 2.4 and 2.6 kernels, compiled - with gcc (the unit-at-a-time optimizations in version 3.4 and later are - worth upgrading to get, but older versions should work), and linked against - uClibc (0.9.27 or greater) or glibc (2.2 or greater). In such an - environment, the full set of busybox features should work, and if - anything doesn't we want to know about it so we can fix it. - - There are many other environments out there, in which busybox may build - and run just fine. We just don't test them. Since busybox consists of a - large number of more or less independent applets, portability is a question - of which features work where. Some busybox applets (such as cat and rm) are - highly portable and likely to work just about anywhere, while others (such as - insmod and losetup) require recent Linux kernels with recent C libraries. - - Earlier versions of Linux and glibc may or may not work, for any given - configuration. Linux 2.2 or earlier should mostly work (there's still - some support code in things like mount.c) but this is no longer regularly - tested, and inherently won't support certain features (such as long files - and --bind mounts). The same is true for glibc 2.0 and 2.1: expect a higher - testing and debugging burden using such old infrastructure. (The busybox - developers are not very interested in supporting these older versions, but - will probably accept small self-contained patches to fix simple problems.) - - Some environments are not recommended. Early versions of uClibc were buggy - and missing many features: upgrade. Linking against libc5 or dietlibc is - not supported and not interesting to the busybox developers. (The first is - obsolete and has no known size or feature advantages over uClibc, the second - has known bugs that its developers have actively refused to fix.) Ancient - Linux kernels (2.0.x and earlier) are similarly uninteresting. - - In theory it's possible to use Busybox under other operating systems (such as - MacOS X, Solaris, Cygwin, or the BSD Fork Du Jour). This generally involves - a different kernel and a different C library at the same time. While it - should be possible to port the majority of the code to work in one of - these environments, don't be surprised if it doesn't work out of the box. If - you're into that sort of thing, start small (selecting just a few applets) - and work your way up. - - In 2005 Shaun Jackman has ported busybox to a combination of newlib - and libgloss, and some of his patches have been integrated. - -Supported hardware: - - BusyBox in general will build on any architecture supported by gcc. We - support both 32 and 64 bit platforms, and both big and little endian - systems. - - Under 2.4 Linux kernels, kernel module loading was implemented in a - platform-specific manner. Busybox's insmod utility has been reported to - work under ARM, CRIS, H8/300, x86, ia64, x86_64, m68k, MIPS, PowerPC, S390, - SH3/4/5, Sparc, v850e, and x86_64. Anything else probably won't work. - - The module loading mechanism for the 2.6 kernel is much more generic, and - we believe 2.6.x kernel module loading support should work on all - architectures supported by the kernel. - ----------------- - -Please feed suggestions, bug reports, insults, and bribes back to the busybox -mailing list: - - busybox@busybox.net - -and/or maintainer: - - Denys Vlasenko - diff --git a/busybox/TODO b/busybox/TODO deleted file mode 100644 index 4436469..0000000 --- a/busybox/TODO +++ /dev/null @@ -1,278 +0,0 @@ -Busybox TODO - -Harvest patches from -http://git.openembedded.org/cgit.cgi/openembedded/tree/recipes/busybox/ -https://dev.openwrt.org/browser/trunk/package/busybox/patches/ - - -Stuff that needs to be done.

(Not unless we - can cleanly export it from our underlying C library without having to - concern ourselves with it directly. Perhaps a few specific things like a - config option for "date" are low hanging fruit here?) - - What level should things happen at? How much do we care about - internationalizing the text console when X11 and xterms are so much better - at it? (There's some infrastructure here we don't implement: The - "unicode_start" and "unicode_stop" shell scripts need "vt-is-UTF8" and a - --unicode option to loadkeys. That implies a real loadkeys/dumpkeys - implementation to replace loadkmap/dumpkmap. Plus messing with console font - loading. Is it worth it, or do we just say "use X"?) - - Individual compilation of applets. - It would be nice if busybox had the option to compile to individual applets, - for people who want an alternate implementation less bloated than the gnu - utils (or simply with less political baggage), but without it being one big - executable. - - Turning libbb into a real dll is another possibility, especially if libbb - could export some of the other library interfaces we've already more or less - got the code for (like zlib). - - buildroot - Make a "dogfood" option - Busybox 1.1 will be capable of replacing most gnu packages for real world - use, such as developing software or in a live CD. It needs wider testing. - - Busybox should now be able to replace bzip2, coreutils, e2fsprogs, file, - findutils, gawk, grep, inetutils, less, modutils, net-tools, patch, procps, - sed, shadow, sysklogd, sysvinit, tar, util-linux, and vim. The resulting - system should be self-hosting (I.E. able to rebuild itself from source - code). This means it would need (at least) binutils, gcc, and make, or - equivalents. - - It would be a good "eating our own dogfood" test if buildroot had the option - of using a "make allyesconfig" busybox instead of the all of the above - packages. Anything that's wrong with the resulting system, we can fix. (It - would be nice to be able to upgrade busybox to be able to replace bash and - diffutils as well, but we're not there yet.) - - One example of an existing system that does this already is Firmware Linux: - http://www.landley.net/code/firmware - - initramfs - Busybox should have a sample initramfs build script. This depends on - shell, mdev, and switch_root. - - mkdep - Write a mkdep that doesn't segfault if there's a directory it doesn't - have permission to read, isn't based on manually editing the output of - lexx and yacc, doesn't make such a mess under include/config, etc. - - Group globals into unions of structures. - Go through and turn all the global and static variables into structures, - and have all those structures be in a big union shared between processes, - so busybox uses less bss. (This is a big win on nommu machines.) See - sed.c and mdev.c for examples. - - Go through bugs.busybox.net and close out all of that somehow. - This one's open to everybody, but I'll wind up doing it... - -Bernhard Reutner-Fischer suggests to look at these: - New debug options: - -Wlarger-than-127 - Cleanup any big users - Collate BUFSIZ IOBUF_SIZE MY_BUF_SIZE PIPE_PROGRESS_SIZE BUFSIZE PIPESIZE - make bb_common_bufsiz1 configurable, size wise. - make pipesize configurable, size wise. - Use bb_common_bufsiz1 throughout applets! - -As yet unclaimed: - ----- -diff - Make sure we handle empty files properly: - From the patch man page: - - you can remove a file by sending out a context diff that compares - the file to be deleted with an empty file dated the Epoch. The - file will be removed unless patch is conforming to POSIX and the - -E or --remove-empty-files option is not given. ---- -patch - Should have simple fuzz factor support to apply patches at an offset which - shouldn't take up too much space. - - And while we're at it, a new patch filename quoting format is apparently - coming soon: http://marc.theaimsgroup.com/?l=git&m=112927316408690&w=2 ---- -stty / catv - stty's visible() function and catv's guts are identical.

Either way, there's no guarantee it'll make it to its final - destination before close() gets called, so there's no guarantee that any - error will be reported. - - You need to call fsync() if you care about errors that occur after write(), - but that can have a big performance impact. So make it a config option. ---- -Unify archivers - Lots of archivers have the same general infrastructure. The directory - traversal code should be factored out, and the guts of each archiver could - be some setup code and a series of callbacks for "add this file", - "add this directory", "add this symlink" and so on. - - This could clean up tar and zip, and make it cheaper to add cpio and ar - write support, and possibly even cheaply add things like mkisofs or - mksquashfs someday, if they become relevant. ---- -Text buffer support. - Several existing applets (sort, vi, less...) read - a whole file into memory and act on it. Use open_read_close(). ---- -Memory Allocation - We have a CONFIG_BUFFER mechanism that lets us select whether to do memory - allocation on the stack or the heap. Unfortunately, we're not using it much. - We need to audit our memory allocations and turn a lot of malloc/free calls - into RESERVE_CONFIG_BUFFER/RELEASE_CONFIG_BUFFER. - For a start, see e.g. make EXTRA_CFLAGS=-Wlarger-than-64 - - And while we're at it, many of the CONFIG_FEATURE_CLEAN_UP #ifdefs will be - optimized out by the compiler in the stack allocation case (since there's no - free for an alloca()), and this means that various cleanup loops that just - call free might also be optimized out by the compiler if written right, so - we can yank those #ifdefs too, and generally clean up the code. ---- -FEATURE_CLEAN_UP - This is more an unresolved issue than a to-do item. More thought is needed. - - Normally we rely on exit() to free memory, close files and unmap segments - for us. This makes most calls to free(), close(), and unmap() optional in - busybox applets that don't intend to run for very long, and optional stuff - can be omitted to save size. - - The idea was raised that we could simulate fork/exit with setjmp/longjmp - for _really_ brainless embedded systems, or speed up the standalone shell - by not forking. Doing so would require a reliable FEATURE_CLEAN_UP. - Unfortunately, this isn't as easy as it sounds. - - The problem is, lots of things exit(), sometimes unexpectedly (xmalloc()) - and sometimes reliably (bb_perror_msg_and_die() or show_usage()). This - jumps out of the normal flow control and bypasses any cleanup code we - put at the end of our applets. - - It's possible to add hooks to libbb functions like xmalloc() and xopen() - to add their entries to a linked list, which could be traversed and - freed/closed automatically. (This would need to be able to free just the - entries after a checkpoint to be usable for a forkless standalone shell. - You don't want to free the shell's own resources.) - - Right now, FEATURE_CLEAN_UP is more or less a debugging aid, to make things - like valgrind happy.

You can skip building - it by omitting CONFIG_XZ_DEC_TEST=m from the make command line. - -Compiler requirements - - XZ Embedded should compile as either GNU-C89 (used in the Linux - kernel) or with any C99 compiler. Getting the code to compile with - non-GNU C89 compiler or a C++ compiler should be quite easy as - long as there is a data type for unsigned 64-bit integer (or the - code is modified not to support large files, which needs some more - care than just using 32-bit integer instead of 64-bit). - - If you use GCC, try to use a recent version. For example, on x86, - xz_dec_lzma2.c compiled with GCC 3.3.6 is 15-25 % slower than when - compiled with GCC 4.3.3. - -Embedding into userspace applications - - To embed the XZ decoder, copy the following files into a single - directory in your source code tree: - - linux/include/linux/xz.h - linux/lib/xz/xz_crc32.c - linux/lib/xz/xz_dec_lzma2.c - linux/lib/xz/xz_dec_stream.c - linux/lib/xz/xz_lzma2.h - linux/lib/xz/xz_private.h - linux/lib/xz/xz_stream.h - userspace/xz_config.h - - Alternatively, xz.h may be placed into a different directory but then - that directory must be in the compiler include path when compiling - the .c files. - - Your code should use only the functions declared in xz.h. The rest of - the .h files are meant only for internal use in XZ Embedded. - - You may want to modify xz_config.h to be more suitable for your build - environment. Probably you should at least skim through it even if the - default file works as is. - -BCJ filter support - - If you want support for one or more BCJ filters, you need to copy also - linux/lib/xz/xz_dec_bcj.c into your application, and use appropriate - #defines in xz_config.h or in compiler flags.

That's why Itanium and SPARC filters work for both big - and little endian executables (Itanium has little endian instructions - and SPARC has big endian instructions). - - There currently is no filter for little endian PowerPC or big endian - ARM or ARM-Thumb. Implementing filters for them can be considered if - there is a need for such filters in real-world applications. - -Notes about shared libraries - - If you are including XZ Embedded into a shared library, you very - probably should rename the xz_* functions to prevent symbol - conflicts in case your library is linked against some other library - or application that also has XZ Embedded in it (which may even be - a different version of XZ Embedded).

Baumann, - - 2. Introduction - - This HOWTO will attempt to give hints about how to write a program - which needs to access a serial port. Its principal focus will be on - the Linux implementation and what the meaning of the various library - functions available. - - Someone asked about which of several sequences of operations was - right. There is no absolute right way to accomplish an outcome. The - options available are too numerous. If your sequences produces the - desired results, then that is the right way for you. Another - programmer may select another set of options and get the same results. - His method is right for him. - - Neither of these methods may operate properly with some other - implementation of UNIX. It is strange that many of the concepts which - were implemented in the SYSV version have been dumped. Because UNIX - was developed by AT&T and much code has been generated on those - concepts, the AT&T version should be the standard to which others - should emulate. - - Now the standard is POSIX. - - It was once stated that the popularity of UNIX and C was that they - were created by programmers for programmers. Not by scholars who - insist on purity of style in deference to results and simplicity of - use. Not by committees with people who have diverse personal or - proprietary agenda. Now ANSI and POSIX have strayed from those - original clear and simply concepts. - - 3. Opening - - The various serial devices are opened just as any other file. - Although, the fopen(3) command may be used, the plain open(2) is - preferred. This call returns the file descriptor which is required - for the various commands that configure the interface. - - Open(2) has the format: - - #include - int open(char *path, int flags, [int mode]); - - In addition to the obvious O_RDWR, O_WRONLY and O_RDONLY, two - additional flags are available. These are O_NONBLOCK and O_NOCTTY. - Other flags listed in the open(2) manual page are not applicable to - serial devices. - - Normally, a serial device opens in "blocking" mode. This means that - the open() will not return until the Carrier Detect line from the port - is active, e.g. modem, is active. When opened with the O_NONBLOCK - flag set, the open() will return immediately regardless of the status - of the DCD line. The "blocking" mode also affects the read() call. - - The fcntl(2) command can be used to change the O_NONBLOCK flag anytime - after the device has been opened. - - The device driver and the data passing through it are controlled - according to settings in the struct termios. This structure is - defined in "/usr/include/termios.h". In the Linux tree, further - reference is made to "/usr/include/asm/termbits.h". - In blocking mode, a read(2) will block until data is available or a - signal is received. It is still subject to state of the ICANON flag. - - When the termios.c_lflag ICANON bit is set, input data is collected - into strings until a NL, EOF or EOL character is received. You can - define these in the termios.c_cc[] array. Also, ERASE and KILL - characters will operate on the incoming data before it is delivered to - the user. - - In non-canonical mode, incoming data is quantified by use of the - c_cc[VMIN and c_cc[VTIME] values in termios.c_cc[]. - - Some programmers use the select() call to detect the completion of a - read(). This is not the best way of checking for incoming data. - Select() is part of the SOCKETS scheme and too complex for most - applications. - - A full explanation of the fields of the termios structure is contained - in termios(7) of the Users Manual. A version is included in Part 2 of - this HOWTO document. - - 4. Commands - - Changes to the struct termios are made by retrieving the current - settings, making the desired changes and transmitting the modified - structure back to the kernel. - - The historic means of communicating with the kernel was by use of the - ioctl(fd, COMMAND, arg) system call. Then the purists in the - computer industry decided that this was not genetically consistent. - Their argument was that the argument changed its stripes. Sometimes - it was an int, sometimes it was a pointer to int and other times it - was a pointer to struct termios. Then there were those times it was - empty or NULL. These variations are dependent upon the COMMAND. - - As a alternative, the tc* series of functions were concocted. - - These are: - - int tcgetattr(int filedes, struct termios *termios_p); - int tcsetattr(int filedes, int optional_actions, - const struct termios *termios_p); - - instead of: - - int ioctl(int filedes, int command, - struct termios *termios_p); - - where command is TCGETS or one of TCSETS, TCSETSW or TCSETSF. - - The TCSETS command is comparable to the TCSANOW optional_action for - the tc* version. These direct the kernel to adopt the changes - immediately. Other pairs are: - - command optional_action Meaning - TCSETSW TCSADRAIN Change after all output has drained. - TCSETSF TCSAFLUSH Change after all output has drained - then discard any input characters - not read. - - Since the return code from either the ioctl(2) or the tcsetattr(2) - commands only indicate that the command was processed by the kernel. - These do not indicate whether or not the changes were actually - accomplished. Either of these commands should be followed by a call - to: - - ioctl(fd, TCGETS, &new_termios); - - or: - - tcgetattr(fd, &new_termios); - - A user function which makes changes to the termios structure should - define two struct termios variables.

Then after the desired configuration has been - sent to the kernel, another call should be made to retrieve the - kernels version. Then the two compared. - - Here is an example of how to add RTS/CTS flow control: - - struct termios my_termios; - struct termios new_termios; - - tcgetattr(fd, &my_termios); - my_termios.c_flag |= CRTSCTS; - tcsetattr(fd, TCSANOW, &my_termios); - tcgetattr(fd, &new_termios); - if (memcmp(my_termios, new_termios, - sizeof(my_termios)) != 0) { - /* do some error handling */ - } - - 5. Changing Baud Rates - - With Linux, the baud rate can be changed using a technique similar to - add/delete RTS/CTS. - - struct termios my_termios; - struct termios new_termios; - - tcgetattr(fd, &my_termios); - my_termios.c_flag &= ~CBAUD; - my_termios.c_flag |= B19200; - tcsetattr(fd, TCSANOW, &my_termios); - tcgetattr(fd, &new_termios); - if (memcmp(my_termios, new_termios, - sizeof(my_termios)) != 0) { - /* do some error handling */ - } - - POSIX adds another method. They define: - - speed_t cfgetispeed(const struct termios *termios_p); - speed_t cfgetospeed(const struct termios *termios_p); - - library calls to extract the current input or output speed from the - struct termios pointed to with *termio_p. This is a variable defined - in the calling process. In practice, the data contained in this - termios, should be obtained by the tcgetattr() call or an ioctl() call - using the TCGETS command. - - The companion library calls are: - - int cfsetispeed(struct termios *termios_p, speed_t speed); - int cfsetospeed(struct termios *termios_p, speed_t speed); - - which are used to change the value of the baud rate in the locally - defined *termios_p. Following either of these calls, either a call to - tcsetattr() or ioctl() with one of TCSETS, TCSETSW or TCSETSF as the - command to transmit the change to the kernel. - - The cf* commands are preferred for portability. Some weird Unices use - a considerably different format of termios. - - Most implementations of Linux use only the input speed for both input - and output. These functions are defined in the application program by - reference to . In reality, they are in - /usr/include/asm/termbits.h. - - 6. Additional Control Calls - - 6.1. Sending a "break". - - int ioctl(fd, TCSBRK, int arg); - int tcsendbreak(fd, int arg); - - Send a break: Here the action differs between the conventional - ioctl() call and the POSIX call. For the conventional call, an arg of - '0' sets the break control line of the UART for 0.25 seconds. For the - POSIX command, the break line is set for arg times 0.1 seconds. - - 6.2. Hardware flow control. - - int ioctl(fd, TCXONC, int action); - int tcflow(fd, int action); - - The action flags are: - - o TCOOFF 0 suspend output - - o TCOON 1 restart output - - o TCIOFF 2 transmit STOP character to suspend input - - o TCION 3 transmit START character to restart input - - 6.3. Flushing I/O buffers. - - int ioctl(fd, TCFLSH, queue_selector); - int tcflush(fd, queue_selector); - - The queue_selector flags are: - - o TCIFLUSH 0 flush any data not yet read from the input buffer - - o TCOFLUSH 1 flush any data written to the output buffer but not - yet transmitted - - o TCIOFLUSH 2 flush both buffers - - 7. Modem control - - The hardware modem control lines can be monitored or modified by the - ioctl(2) system call. A set of comparable tc* calls apparently do not - exist. The form of this call is: - - int ioctl(fd, COMMAND, (int *)flags); - - The COMMANDS and their action are: - - o TIOCMBIS turn on control lines depending upon which bits are set - in flags. - - o TIOCMBIC turn off control lines depending upon which bits are - unset in flags. - o TIOCMGET the appropriate bits are set in flags according to the - current status - - o TIOCMSET the state of the UART is changed according to which bits - are set/unset in 'flags' - - The bit pattern of flags refer to the following control lines: - - o TIOCM_LE Line enable - - o TIOCM_DTR Data Terminal Ready - - o TIOCM_RTS Request to send - - o TIOCM_ST Secondary transmit - - o TIOCM_SR Secondary receive - - o TIOCM_CTS Clear to send - - o TIOCM_CAR Carrier detect - - o TIOCM_RNG Ring - - o TIOCM_DSR Data set ready - - It should be noted that some of these bits are controlled by the modem - and the UART cannot change them but their status can be sensed by - TIOCMGET. Also, most Personal Computers do not provide hardware for - secondary transmit and receive. - - There are also a pair of ioctl() to monitor these lines. They are - undocumented as far as I have learned. The commands are TIOCMIWAIT - and TCIOGICOUNT.

It provides minimalist replacements for most of the utilities -you usually find in GNU coreutils, util-linux, etc. The utilities in BusyBox -generally have fewer options than their full-featured GNU cousins; however, the -options that are included provide the expected functionality and behave very -much like their GNU counterparts. - -BusyBox has been written with size-optimization and limited resources in mind. -It is also extremely modular so you can easily include or exclude commands (or -features) at compile time. This makes it easy to customize your embedded -systems. To create a working system, just add /dev, /etc, and a Linux kernel. -BusyBox provides a fairly complete POSIX environment for any small or embedded -system. - -BusyBox is extremely configurable. This allows you to include only the -components you need, thereby reducing binary size. Run 'make config' or 'make -menuconfig' to select the functionality that you wish to enable. Then run -'make' to compile BusyBox using your configuration. - -After the compile has finished, you should use 'make install' to install -BusyBox. This will install the 'bin/busybox' binary, in the target directory -specified by CONFIG_PREFIX. CONFIG_PREFIX can be set when configuring BusyBox, -or you can specify an alternative location at install time (i.e., with a -command line like 'make CONFIG_PREFIX=/tmp/foo install'). If you enabled -any applet installation scheme (either as symlinks or hardlinks), these will -also be installed in the location pointed to by CONFIG_PREFIX. - -=head1 USAGE - -BusyBox is a multi-call binary. A multi-call binary is an executable program -that performs the same job as more than one utility program. That means there -is just a single BusyBox binary, but that single binary acts like a large -number of utilities. This allows BusyBox to be smaller since all the built-in -utility programs (we call them applets) can share code for many common -operations. - -You can also invoke BusyBox by issuing a command as an argument on the -command line. For example, entering - - /bin/busybox ls - -will also cause BusyBox to behave as 'ls'. - -Of course, adding '/bin/busybox' into every command would be painful. So most -people will invoke BusyBox using links to the BusyBox binary. - -For example, entering - - ln -s /bin/busybox ls - ./ls - -will cause BusyBox to behave as 'ls' (if the 'ls' command has been compiled -into BusyBox). Generally speaking, you should never need to make all these -links yourself, as the BusyBox build system will do this for you when you run -the 'make install' command. - -If you invoke BusyBox with no arguments, it will provide you with a list of the -applets that have been compiled into your BusyBox binary. - -=head1 COMMON OPTIONS - -Most BusyBox applets support the B<--help> argument to provide a terse runtime -description of their behavior. If the CONFIG_FEATURE_VERBOSE_USAGE option has -been enabled, more detailed usage information will also be available. - -=head1 COMMANDS - -Currently available applets include: diff --git a/busybox/docs/cgi/cl.html b/busybox/docs/cgi/cl.html deleted file mode 100644 index 4f8faae..0000000 --- a/busybox/docs/cgi/cl.html +++ /dev/null @@ -1,46 +0,0 @@ -CGI Command line options

CGI Command line options

Specification

- -The command line is only used in the case of an ISINDEX query. It is -not used in the case of an HTML form or any as yet undefined query -type. The server should search the query information (the QUERY_STRING environment variable) for a non-encoded -= character to determine if the command line is to be used, if it -finds one, the command line is not to be used. This trusts the clients -to encode the = sign in ISINDEX queries, a practice which was -considered safe at the time of the design of this specification.

- -For example, use the finger script and the ISINDEX interface to look up "httpd". You will see that the script will call itself with /cgi-bin/finger?httpd and will actually execute "finger httpd" on the command line and output the results to you. -

-If the server does find a "=" in the QUERY_STRING, -then the command line will not be used, and no decoding will be -performed. The query then remains intact for processing by an -appropriate FORM submission decoder. -Again, as an example, use this hyperlink to submit "httpd=name" to the finger script. Since this QUERY_STRING -contained an unencoded "=", nothing was decoded, the script didn't know -it was being submitted a valid query, and just gave you the default -finger form. -

-If the server finds that it cannot send the string due to internal -limitations (such as exec() or /bin/sh command line restrictions) the -server should include NO command line information and provide the -non-decoded query information in the environment -variable QUERY_STRING.

-

-

Examples

- -Examples of the command line usage are much better demonstrated than explained. For these -examples, pay close attention to the script output which says what -argc and argv are.

CGI Environment Variables

-
- -

- -In order to pass data about the information request from the server to -the script, the server uses command line arguments as well as -environment variables. These environment variables are set when the -server executes the gateway program.

- -

-

Specification

- -

-The following environment variables are not request-specific and are -set for all requests:

- -

    -
  • SERVER_SOFTWARE

    - - The name and version of the information server software answering - the request (and running the gateway). Format: name/version

    - -

  • SERVER_NAME

    - The server's hostname, DNS alias, or IP address as it would appear - in self-referencing URLs.

    - -

  • GATEWAY_INTERFACE

    - The revision of the CGI specification to which this server - complies. Format: CGI/revision

    - -

- -
- -The following environment variables are specific to the request being -fulfilled by the gateway program:

- -

    -
  • SERVER_PROTOCOL

    - The name and revision of the information protcol this request came - in with. Format: protocol/revision

    - -

  • SERVER_PORT

    - The port number to which the request was sent.

    - -

  • REQUEST_METHOD

    - The method with which the request was made. For HTTP, this is - "GET", "HEAD", "POST", etc.

    - -

  • PATH_INFO

    - The extra path information, as given by the client. In other - words, scripts can be accessed by their virtual pathname, followed - by extra information at the end of this path. The extra - information is sent as PATH_INFO. This information should be - decoded by the server if it comes from a URL before it is passed - to the CGI script.

    - -

  • PATH_TRANSLATED

    - The server provides a translated version of PATH_INFO, which takes - the path and does any virtual-to-physical mapping to it.

    - -

  • SCRIPT_NAME

    - A virtual path to the script being executed, used for - self-referencing URLs.

    - -

  • QUERY_STRING

    - The information which follows the ? in the URL - which referenced this script. This is the query information. It - should not be decoded in any fashion. This variable should always - be set when there is query information, regardless of command line decoding.

    - -

  • REMOTE_HOST

    - The hostname making the request. If the server does not have this - information, it should set REMOTE_ADDR and leave this unset.

    - -

  • REMOTE_ADDR

    - The IP address of the remote host making the request.

    - -

  • AUTH_TYPE

    - If the server supports user authentication, and the script is - protects, this is the protocol-specific authentication method used - to validate the user.

    - -

  • REMOTE_USER

    - If the server supports user authentication, and the script is - protected, this is the username they have authenticated as.

    -

  • REMOTE_IDENT

    - If the HTTP server supports RFC 931 identification, then this - variable will be set to the remote user name retrieved from the - server. Usage of this variable should be limited to logging only. -

    - -

  • CONTENT_TYPE

    - For queries which have attached information, such as HTTP POST and - PUT, this is the content type of the data.

    - -

  • CONTENT_LENGTH

    - The length of the said content as given by the client.

    - -

- - -
 - -In addition to these, the header lines received from the client, if -any, are placed into the environment with the prefix HTTP_ followed by -the header name. Any - characters in the header name are changed to _ -characters. The server may exclude any headers which it has already -processed, such as Authorization, Content-type, and Content-length. If -necessary, the server may choose to exclude any or all of these -headers if including them would exceed any system environment -limits.

- -An example of this is the HTTP_ACCEPT variable which was defined in -CGI/1.0. Another example is the header User-Agent.

- -

    -
  • HTTP_ACCEPT

    - The MIME types which the client will accept, as given by HTTP - headers. Other protocols may need to get this information from - elsewhere. Each item in this list should be separated by commas as - per the HTTP spec.

    - - Format: type/subtype, type/subtype

    - - -

  • HTTP_USER_AGENT

    - - The browser the client is using to send the request. General -format: software/version library/version.

CGI Script Input

Specification

- -For requests which have information attached after the header, such as -HTTP POST or PUT, the information will be sent to the script on stdin. -

Example

- -Let's take a form with METHOD="POST" as an example. Let's say the form -results are 7 bytes encoded, and look like a=b&b=c. -

- -In this case, the server will set CONTENT_LENGTH to 7 and CONTENT_TYPE -to application/x-www-form-urlencoded. The first byte on the script's -standard input will be "a", followed by the rest of the encoded string.

CGI Script Output

-
- -

Script output

- -The script sends its output to stdout. This output can either be a -document generated by the script, or instructions to the server for -retrieving the desired output.

-

- -

Script naming conventions

- -Normally, scripts produce output which is interpreted and sent back to -the client. An advantage of this is that the scripts do not need to -send a full HTTP/1.0 header for every request.

- -Some scripts may want to avoid the extra overhead of the server -parsing their output, and talk directly to the client. In order to -distinguish these scripts from the other scripts, CGI requires that -the script name begins with nph- if a script does not want the server -to parse its header. In this case, it is the script's responsibility -to return a valid HTTP/1.0 (or HTTP/0.9) response to the client.

- -

-

Parsed headers

- -The output of scripts begins with a small header. This header consists -of text lines, in the same format as an -HTTP header, terminated by a blank line (a line with only a -linefeed or CR/LF).

- -Any headers which are not server directives are sent directly back to -the client. Currently, this specification defines three server -directives:

- -

    -
  • Content-type

    - - This is the MIME type of the document you are returning.

    - -

  • Location

    - - This is used to specify to the server that you are returning a - reference to a document rather than an actual document.

    - - If the argument to this is a URL, the server will issue a redirect - to the client.

    - - If the argument to this is a virtual path, the server will - retrieve the document specified as if the client had requested - that document originally. ? directives will work in here, but # - directives must be redirected back to the client.

    - - -

  • Status

    - - This is used to give the server an HTTP/1.0 status -line to send to the client. The format is nnn xxxxx, -where nnn is the 3-digit status code, and -xxxxx is the reason string, such as "Forbidden".

    - -

- -
-

Examples

- -Let's say I have a fromgratz to HTML converter. When my converter is -finished with its work, it will output the following on stdout (note -that the lines beginning and ending with --- are just for illustration -and would not be output):

- -

--- start of output ---
-Content-type: text/html
-
---- end of output ---
-
- -Note the blank line after Content-type.

- -Now, let's say I have a script which, in certain instances, wants to -return the document /path/doc.txt from this server just -as if the user had actually requested -http://server:port/path/doc.txt to begin with. In this -case, the script would output:

-

--- start of output ---
-Location: /path/doc.txt
-
---- end of output ---
-
- -The server would then perform the request and send it to the client. -

- -Let's say that I have a script which wants to reference our gopher -server. In this case, if the script wanted to refer the user to -gopher://gopher.ncsa.uiuc.edu/, it would output:

- -

--- start of output ---
-Location: gopher://gopher.ncsa.uiuc.edu/
-
---- end of output ---
-
- -Finally, I have a script which wants to talk to the client directly. -In this case, if the script is referenced with SERVER_PROTOCOL of HTTP/1.0, -the script would output the following HTTP/1.0 response:

- -

-Content-type: text/plain
-

Somebody might have even added the feature you had in mind. -Don't make your work obsolete before you start! - -For information on how to check out Busybox development tree, please look at the -following links: - - http://busybox.net/source.html - - -Read the Mailing List -~~~~~~~~~~~~~~~~~~~~~ - -No one is required to read the entire archives of the mailing list, but you -should at least read up on what people have been talking about lately. If -you've recently discovered a problem, chances are somebody else has too.

To find the maintainer of an applet, look at the top of the .c file -for a name following the word 'Copyright' or 'Written by' or 'Maintainer'. - -Before plunging ahead, it's a good idea to send a message to the mailing list -that says: "Hey, I was thinking about adding the 'transmogrify' feature to the -'foo' applet. Would this be useful? Is anyone else working on it?" You might -want to CC the maintainer (if any) with your question. - - - -Areas Where You Can Help ------------------------- - -Busybox can always use improvement! If you're looking for ways to help, there -are a variety of areas where you could help. - - -What Busybox Doesn't Need -~~~~~~~~~~~~~~~~~~~~~~~~~ - -Before listing the areas where you _can_ help, it's worthwhile to mention the -areas where you shouldn't bother. While Busybox strives to be the "Swiss Army -Knife" of embedded Linux, there are some applets that will not be accepted: - - - Any filesystem manipulation tools: Busybox is filesystem independent and - we do not want to start adding mkfs/fsck tools for every (or any) - filesystem under the sun. (fsck_minix.c and mkfs_minix.c are living on - borrowed time.) There are far too many of these tools out there. Use - the upstream version. Rationale: bugs in these tools can destroy - vast amounts of data. Keeping up with filesystem format development - is impractical (especially in the area of keeping fsck tool safe - and up-to-date). - - - Any disk, device, or media-specific tools: Use the -utils or -tools package - that was designed for your device; don't try to shoehorn them into Busybox. - - - Any architecture specific tools: Busybox is (or should be) architecture - independent. Do not send us tools that cannot be used across multiple - platforms / arches. - - -Bug Reporting -~~~~~~~~~~~~~ - -If you find bugs, please submit a detailed bug report to the busybox mailing -list at busybox@busybox.net.

Just make -sure you're in the busybox/ directory and type: - - git diff -b -w > mychanges.patch - -You can send the resulting .patch file to the mailing list with a description -of what it does. (But not before you test it! See the next section for some -guidelines.) It is preferred that patches be sent as attachments, but it is -not required. - -Also, feel free to help test other people's patches and reply to them with -comments. You can apply a patch by saving it into your busybox/ directory and -typing: - - patch -p1 < mychanges.patch - -Then you can recompile, see if it runs, test if it works as advertised, and -post your findings to the mailing list. - -NOTE: Please do not include extraneous or irrelevant changes in your patches. -Please do not try to "bundle" two patches together into one. Make single, -discreet changes on a per-patch basis. Sometimes you need to make a patch that -touches code in many places, but these kind of patches are rare and should be -coordinated with a maintainer. - - -Testing Guidelines -~~~~~~~~~~~~~~~~~~ - -It's considered good form to test your new feature before you submit a patch -to the mailing list, and especially before you push a change to Git. Here -are some guidelines on how to test your changes. - - - Always test Busybox applets against GNU counterparts and make sure the - behavior / output is identical between the two. - - - Try several different permutations and combinations of the features you're - adding (i.e., different combinations of command-line switches) and make sure - they all work; make sure one feature does not interfere with another. - - - Make sure you test compiling against the source both with the feature - turned on and turned off in Config.h and make sure Busybox compiles cleanly - both ways. - - - Run the multibuild.pl script in the tests directory and make sure - everything checks out OK. (Do this from within the busybox/ directory by - typing: 'tests/multibuild.pl'.) - - -Making Sure Your Patch Doesn't Get Lost -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -If you don't want your patch to be lost or forgotten, send it to the busybox -mailing list with a subject line something like this: - - [PATCH] - Adds "transmogrify" feature to "foo" - -In the body, you should have a pseudo-header that looks like the following: - - Package: busybox - Version: v1.01pre (or whatever the current version is) - Severity: wishlist - -The remainder of the body should read along these lines: - - This patch adds the "transmogrify" feature to the "foo" applet. I have - tested this on [arch] system(s) and it works. I have tested it against the - GNU counterparts and the outputs are identical. I have run the scripts in - the 'tests' directory and nothing breaks. - - - -Improving Your Chances of Patch Acceptance ------------------------------------------- - -Even after you send a brilliant patch to the mailing list, sometimes it can go -unnoticed, un-replied-to, and sometimes (sigh) even lost. This is an -unfortunate fact of life, but there are steps you can take to help your patch -get noticed and convince a maintainer that it should be added: - - -Be Succinct -~~~~~~~~~~~ - -A patch that includes small, isolated, obvious changes is more likely to be -accepted than a patch that touches code in lots of different places or makes -sweeping, dubious changes. - - -Back It Up -~~~~~~~~~~ - -Hard facts on why your patch is better than the existing code will go a long -way toward convincing maintainers that your patch should be included. -Specifically, patches are more likely to be accepted if they are provably more -correct, smaller, faster, simpler, or more maintainable than the existing -code. - -Conversely, any patch that is supported with nothing more than "I think this -would be cool" or "this patch is good because I say it is and I've got a Phd -in Computer Science" will likely be ignored. - - -Follow The Style Guide -~~~~~~~~~~~~~~~~~~~~~~ - -It's considered good form to abide by the established coding style used in a -project; Busybox is no exception. We have gone so far as to delineate the -"elements of Busybox style" in the file docs/style-guide.txt. Please follow -them. - - -Work With Someone Else -~~~~~~~~~~~~~~~~~~~~~~ - -Working on a patch in isolation is less effective than working with someone -else for a variety of reasons. If another Busybox user is interested in what -you're doing, then it's two (or more) voices instead of one that can petition -for inclusion of the patch. You'll also have more people that can test your -changes, or even offer suggestions on better approaches you could take. - -Getting other folks interested follows as a natural course if you've received -responses from queries to applet maintainer or positive responses from folks -on the mailing list. - -We've made strident efforts to put a useful "collaboration" infrastructure in -place in the form of mailing lists, the bug tracking system, and Git. Please -use these resources. - - -Send Patches to the Bug Tracking System -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -This was mentioned above in the "Making Sure Your Patch Doesn't Get Lost" -section, but it is worth mentioning again. A patch sent to the mailing list -might be unnoticed and forgotten. A patch sent to the bug tracking system will -be stored and closely connected to the bug it fixes. - - -Be Polite -~~~~~~~~~ - -The old saying "You'll catch more flies with honey than you will with vinegar" -applies when submitting patches to the mailing list for approval. The way you -present your patch is sometimes just as important as the actual patch itself -(if not more so). Being rude to the maintainers is not an effective way to -convince them that your patch should be included; it will likely have the -opposite effect. - - - -Pushing Changes to Git ----------------------- - -If you submit several patches that demonstrate that you are a skilled and wise -coder, you may be invited to become a committer, thus enabling you to push -changes directly to Git. This is nice because you don't have to wait for -someone else to push your change for you, you can just do it yourself. - -But note that this is a privilege that comes with some responsibilities. You -should test your changes before you push them. You should also talk to an -applet maintainer before you make any kind of sweeping changes to somebody -else's code. Big changes should still go to the mailing list first. Remember, -being wise, polite, and discreet is more important than being clever. - -For more information on Git push access, see: - - http://busybox.net/developer.html - - -When To Push -~~~~~~~~~~~~ - -Generally, you should feel free to push a change if: - - - Your changes are small and don't touch many files - - You are fixing a bug - - Somebody has told you that it's okay - - It's obviously the Right Thing - -The more of the above are true, the better it is to just push a change -directly to Git. - - -When Not To Push -~~~~~~~~~~~~~~~~ - -Even if you have push access, you should probably still post a patch to the -mailing list if: - - - Your changes are broad and touch many different files - - You are adding a feature - - Your changes are speculative or experimental (i.e., trying a new algorithm) - - You are not the maintainer and your changes make the maintainer cringe - -The more of the above are true, the better it is to post a patch to the -mailing list instead of pushing. - - - -Final Words ------------ - -If all of this seems complicated, don't panic, it's really not that tough. If -you're having difficulty following some of the steps outlined in this -document don't worry, the folks on the Busybox mailing list are a fairly -good-natured bunch and will work with you to help get your patches into shape -or help you make contributions. diff --git a/busybox/docs/ctty.htm b/busybox/docs/ctty.htm deleted file mode 100644 index 3cb2dd2..0000000 --- a/busybox/docs/ctty.htm +++ /dev/null @@ -1,479 +0,0 @@ - - - - The Linux kernel: Processes - - -

10. Processes

- -

Before looking at the Linux implementation, first a general Unix -description of threads, processes, process groups and sessions. -

-(See also General Terminal Interface) -

A session contains a number of process groups, and a process group -contains a number of processes, and a process contains a number -of threads. -

A session can have a controlling tty. -At most one process group in a session can be a foreground process group. -An interrupt character typed on a tty ("Teletype", i.e., terminal) -causes a signal to be sent to all members of the foreground process group -in the session (if any) that has that tty as controlling tty. -

All these objects have numbers, and we have thread IDs, process IDs, -process group IDs and session IDs. -

-

10.1 Processes -

- -

-

Creation

- -

A new process is traditionally started using the fork() -system call: -

-
pid_t p;
-
-p = fork();
-if (p == (pid_t) -1)
-        /* ERROR */
-else if (p == 0)
-        /* CHILD */
-else
-        /* PARENT */
-
-
-

This creates a child as a duplicate of its parent. -Parent and child are identical in almost all respects. -In the code they are distinguished by the fact that the parent -learns the process ID of its child, while fork() -returns 0 in the child. (It can find the process ID of its -parent using the getppid() system call.) -

-

Termination

- -

Normal termination is when the process does -

-
exit(n);
-
-
- -or -
-
return n;
-
-
- -from its main() procedure. It returns the single byte n -to its parent. -

Abnormal termination is usually caused by a signal. -

-

Collecting the exit code. Zombies

- -

The parent does -

-
pid_t p;
-int status;
-
-p = wait(&status);
-
-
- -and collects two bytes: -

-

- - - -

A process that has terminated but has not yet been waited for -is a zombie. It need only store these two bytes: -exit code and reason for termination. -

On the other hand, if the parent dies first, init (process 1) -inherits the child and becomes its parent. -

-

Signals

- -

-

Stopping

- -

Some signals cause a process to stop: -SIGSTOP (stop!), -SIGTSTP (stop from tty: probably ^Z was typed), -SIGTTIN (tty input asked by background process), -SIGTTOU (tty output sent by background process, and this was -disallowed by stty tostop). -

Apart from ^Z there also is ^Y. The former stops the process -when it is typed, the latter stops it when it is read. -

Signals generated by typing the corresponding character on some tty -are sent to all processes that are in the foreground process group -of the session that has that tty as controlling tty. (Details below.) -

If a process is being traced, every signal will stop it. -

-

Continuing

- -

SIGCONT: continue a stopped process. -

-

Terminating

- -

SIGKILL (die! now!), -SIGTERM (please, go away), -SIGHUP (modem hangup), -SIGINT (^C), -SIGQUIT (^\), etc. -Many signals have as default action to kill the target. -(Sometimes with an additional core dump, when such is -allowed by rlimit.) -The signals SIGCHLD and SIGWINCH -are ignored by default. -All except SIGKILL and SIGSTOP can be -caught or ignored or blocked. -For details, see signal(7). -

-

10.2 Process groups -

- -

Every process is member of a unique process group, -identified by its process group ID. -(When the process is created, it becomes a member of the process group -of its parent.) -By convention, the process group ID of a process group -equals the process ID of the first member of the process group, -called the process group leader. -A process finds the ID of its process group using the system call -getpgrp(), or, equivalently, getpgid(0). -One finds the process group ID of process p using -getpgid(p). -

One may use the command ps j to see PPID (parent process ID), -PID (process ID), PGID (process group ID) and SID (session ID) -of processes. With a shell that does not know about job control, -like ash, each of its children will be in the same session -and have the same process group as the shell. With a shell that knows -about job control, like bash, the processes of one pipeline, like -

-
% cat paper | ideal | pic | tbl | eqn | ditroff > out
-
-
- -form a single process group. -

-

Creation

- -

A process pid is put into the process group pgid by -

-
setpgid(pid, pgid);
-
-
- -If pgid == pid or pgid == 0 then this creates -a new process group with process group leader pid. -Otherwise, this puts pid into the already existing -process group pgid. -A zero pid refers to the current process. -The call setpgrp() is equivalent to setpgid(0,0). -

-

Restrictions on setpgid()

- -

The calling process must be pid itself, or its parent, -and the parent can only do this before pid has done -exec(), and only when both belong to the same session. -It is an error if process pid is a session leader -(and this call would change its pgid). -

-

Typical sequence

- -

-

-
p = fork();
-if (p == (pid_t) -1) {
-        /* ERROR */
-} else if (p == 0) {    /* CHILD */
-        setpgid(0, pgid);
-        ...
-} else {                /* PARENT */
-        setpgid(p, pgid);
-        ...
-}
-
-
- -This ensures that regardless of whether parent or child is scheduled -first, the process group setting is as expected by both. -

-

Signalling and waiting

- -

One can signal all members of a process group: -

-
killpg(pgrp, sig);
-
-
-

One can wait for children in ones own process group: -

-
waitpid(0, &status, ...);
-
-
- -or in a specified process group: -
-
waitpid(-pgrp, &status, ...);
-
-
-

-

Foreground process group

- -

Among the process groups in a session at most one can be -the foreground process group of that session. -The tty input and tty signals (signals generated by ^C, ^Z, etc.) -go to processes in this foreground process group. -

A process can determine the foreground process group in its session -using tcgetpgrp(fd), where fd refers to its -controlling tty. If there is none, this returns a random value -larger than 1 that is not a process group ID. -

A process can set the foreground process group in its session -using tcsetpgrp(fd,pgrp), where fd refers to its -controlling tty, and pgrp is a process group in -its session, and this session still is associated to the controlling -tty of the calling process. -

How does one get fd? By definition, /dev/tty -refers to the controlling tty, entirely independent of redirects -of standard input and output. (There is also the function -ctermid() to get the name of the controlling terminal. -On a POSIX standard system it will return /dev/tty.) -Opening the name of the -controlling tty gives a file descriptor fd. -

-

Background process groups

- -

All process groups in a session that are not foreground -process group are background process groups. -Since the user at the keyboard is interacting with foreground -processes, background processes should stay away from it. -When a background process reads from the terminal it gets -a SIGTTIN signal. Normally, that will stop it, the job control shell -notices and tells the user, who can say fg to continue -this background process as a foreground process, and then this -process can read from the terminal. But if the background process -ignores or blocks the SIGTTIN signal, or if its process group -is orphaned (see below), then the read() returns an EIO error, -and no signal is sent. (Indeed, the idea is to tell the process -that reading from the terminal is not allowed right now. -If it wouldn't see the signal, then it will see the error return.) -

When a background process writes to the terminal, it may get -a SIGTTOU signal. May: namely, when the flag that this must happen -is set (it is off by default). One can set the flag by -

-
% stty tostop
-
-
- -and clear it again by -
-
% stty -tostop
-
-
- -and inspect it by -
-
% stty -a
-
-
- -Again, if TOSTOP is set but the background process ignores or blocks -the SIGTTOU signal, or if its process group is orphaned (see below), -then the write() returns an EIO error, and no signal is sent. -[vda: correction. SUS says that if SIGTTOU is blocked/ignored, write succeeds. ] -

-

Orphaned process groups

- -

The process group leader is the first member of the process group. -It may terminate before the others, and then the process group is -without leader. -

A process group is called orphaned when the -parent of every member is either in the process group -or outside the session. -In particular, the process group of the session leader -is always orphaned. -

If termination of a process causes a process group to become -orphaned, and some member is stopped, then all are sent first SIGHUP -and then SIGCONT. -

The idea is that perhaps the parent of the process group leader -is a job control shell. (In the same session but a different -process group.) As long as this parent is alive, it can -handle the stopping and starting of members in the process group. -When it dies, there may be nobody to continue stopped processes. -Therefore, these stopped processes are sent SIGHUP, so that they -die unless they catch or ignore it, and then SIGCONT to continue them. -

Note that the process group of the session leader is already -orphaned, so no signals are sent when the session leader dies. -

Note also that a process group can become orphaned in two ways -by termination of a process: either it was a parent and not itself -in the process group, or it was the last element of the process group -with a parent outside but in the same session. -Furthermore, that a process group can become orphaned -other than by termination of a process, namely when some -member is moved to a different process group. -

-

10.3 Sessions -

- -

Every process group is in a unique session. -(When the process is created, it becomes a member of the session -of its parent.) -By convention, the session ID of a session -equals the process ID of the first member of the session, -called the session leader. -A process finds the ID of its session using the system call -getsid(). -

Every session may have a controlling tty, -that then also is called the controlling tty of each of -its member processes. -A file descriptor for the controlling tty is obtained by -opening /dev/tty. (And when that fails, there was no -controlling tty.) Given a file descriptor for the controlling tty, -one may obtain the SID using tcgetsid(fd). -

A session is often set up by a login process. The terminal -on which one is logged in then becomes the controlling tty -of the session. All processes that are descendants of the -login process will in general be members of the session. -

-

Creation

- -

A new session is created by -

-
pid = setsid();
-
-
- -This is allowed only when the current process is not a process group leader. -In order to be sure of that we fork first: -
-
p = fork();
-if (p) exit(0);
-pid = setsid();
-
-
- -The result is that the current process (with process ID pid) -becomes session leader of a new session with session ID pid. -Moreover, it becomes process group leader of a new process group. -Both session and process group contain only the single process pid. -Furthermore, this process has no controlling tty. -

The restriction that the current process must not be a process group leader -is needed: otherwise its PID serves as PGID of some existing process group -and cannot be used as the PGID of a new process group. -

-

Getting a controlling tty

- -

How does one get a controlling terminal? Nobody knows, -this is a great mystery. -

The System V approach is that the first tty opened by the process -becomes its controlling tty. -

The BSD approach is that one has to explicitly call -

-
ioctl(fd, TIOCSCTTY, 0/1);
-
-
- -to get a controlling tty. -

Linux tries to be compatible with both, as always, and this -results in a very obscure complex of conditions. Roughly: -

The TIOCSCTTY ioctl will give us a controlling tty, -provided that (i) the current process is a session leader, -and (ii) it does not yet have a controlling tty, and -(iii) maybe the tty should not already control some other session; -if it does it is an error if we aren't root, or we steal the tty -if we are all-powerful. -[vda: correction: third parameter controls this: if 1, we steal tty from -any such session, if 0, we don't steal] -

Opening some terminal will give us a controlling tty, -provided that (i) the current process is a session leader, and -(ii) it does not yet have a controlling tty, and -(iii) the tty does not already control some other session, and -(iv) the open did not have the O_NOCTTY flag, and -(v) the tty is not the foreground VT, and -(vi) the tty is not the console, and -(vii) maybe the tty should not be master or slave pty. -

-

Getting rid of a controlling tty

- -

If a process wants to continue as a daemon, it must detach itself -from its controlling tty. Above we saw that setsid() -will remove the controlling tty. Also the ioctl TIOCNOTTY does this. -Moreover, in order not to get a controlling tty again as soon as it -opens a tty, the process has to fork once more, to assure that it -is not a session leader. Typical code fragment: -

-

        if ((fork()) != 0)
-                exit(0);
-        setsid();
-        if ((fork()) != 0)
-                exit(0);
-
-

See also daemon(3). -

-

Disconnect

- -

If the terminal goes away by modem hangup, and the line was not local, -then a SIGHUP is sent to the session leader. -Any further reads from the gone terminal return EOF. -(Or possibly -1 with errno set to EIO.) -

If the terminal is the slave side of a pseudotty, and the master side -is closed (for the last time), then a SIGHUP is sent to the foreground -process group of the slave side. -

When the session leader dies, a SIGHUP is sent to all processes -in the foreground process group. Moreover, the terminal stops being -the controlling terminal of this session (so that it can become -the controlling terminal of another session). -

Thus, if the terminal goes away and the session leader is -a job control shell, then it can handle things for its descendants, -e.g. by sending them again a SIGHUP. -If on the other hand the session leader is an innocent process -that does not catch SIGHUP, it will die, and all foreground processes -get a SIGHUP. -

A process can have several threads. New threads (with the same PID -as the parent thread) are started using the clone system -call using the CLONE_THREAD flag. Threads are distinguished -by a thread ID (TID). An ordinary process has a single thread -with TID equal to PID. The system call gettid() returns the -TID. The system call tkill() sends a signal to a single thread. -

Example: a process with two threads. Both only print PID and TID and exit. -(Linux 2.4.19 or later.) -

- The WWW Common Gateway Interface -
- Version 1.1 -

- - - -

- - Abstract - -

-

- The Common Gateway Interface (CGI) is a simple interface for running - external programs, software or gateways under an information server - in a platform-independent manner. Currently, the supported information - servers are HTTP servers. -

-

- The interface has been in use by the World-Wide Web since 1993. This - specification defines the - "current practice" parameters of the - 'CGI/1.1' interface developed and documented at the U.S. National - Centre for Supercomputing Applications [NCSA-CGI]. - This document also defines the use of the CGI/1.1 interface - on the Unix and AmigaDOS(tm) systems. -

-

- Discussion of this draft occurs on the CGI-WG mailing list; see the - project Web page at - <URL:http://CGI-Spec.Golux.Com/> - for details on the mailing list and the status of the project. -

-
Revision 01, released 28 December 1998 -
- Major structure change: Section 4, "Request Metadata (Meta-Variables)" - was moved entirely under Section 7, "Data Input to the - CGI Script." - Due to the size of this change, it is noted here and the text in its - former location does not appear as struckthrough. This has - caused major sections 5 and following to decrement - by one. Other - large text movements are likewise not marked up. References to RFC - 1738 were changed to 2396 (1738's replacement). -

Revision 02, released 2 April, 1999 -
- Added text to section 8.3 defining correct handling - of HTTP/1.1 - requests using "chunked" Transfer-Encoding. Labelled metavariable - names in section 8 with the appropriate detail section - numbers. - Clarified allowed usage of Status and - Location response header fields.

Revision 03, released 25 June 1999 -
- Changed references from "HTTP" to "Protocol-Specific" for the listing of - things like HTTP_ACCEPT. Changed 'entity-body' and 'content-body' to - 'message-body.' Added a note that response headers must comply with - requirements of the protocol level in use. Added a lot of stuff about - security (section 11). Clarified a bunch of productions. Pointed out - that zero-length and omitted values are indistinguishable in this - specification. Clarified production describing order of fields in - script response header. Clarified issues surrounding encoding of - data. Acknowledged additional contributors, and changed one of - the authors' addresses. -

- - 1. Introduction - -

- -

- - 1.1. Purpose - -

-

- Together the HTTP [3,8] server - and the CGI script are responsible - for servicing a client - request by sending back responses. The client - request comprises a Universal Resource Identifier (URI) - [1], a - request method, and various ancillary - information about the request - provided by the transport mechanism. -

-

- The CGI defines the abstract parameters, known as - metavariables, - which describe the client's - request. Together with a - concrete programmer interface this specifies a platform-independent - interface between the script and the HTTP server. -

- -

- - 1.2. Requirements - -

-

- This specification uses the same words as RFC 1123 - [5] to define the - significance of each particular requirement. These are: -

-

-
-
MUST -
-
-

- This word or the adjective 'required' means that the item is an - absolute requirement of the specification. -

-
-
SHOULD -
-
-

- This word or the adjective 'recommended' means that there may - exist valid reasons in particular circumstances to ignore this - item, but the full implications should be understood and the case - carefully weighed before choosing a different course. -

-
-
MAY -
-
-

- This word or the adjective 'optional' means that this item is - truly optional. One vendor may choose to include the item because - a particular marketplace requires it or because it enhances the - product, for example; another vendor may omit the same item. -

-
-
-

- An implementation is not compliant if it fails to satisfy one or more - of the 'must' requirements for the protocols it implements. An - implementation that satisfies all of the 'must' and all of the - 'should' requirements for its features is said to be 'unconditionally - compliant'; one that satisfies all of the 'must' requirements but not - all of the 'should' requirements for its features is said to be - 'conditionally compliant.' -

- -

- - 1.3. Specifications - -

-

- Not all of the functions and features of the CGI are defined in the - main part of this specification. The following phrases are used to - describe the features which are not specified: -

-
-
system defined -
-
-

- The feature may differ between systems, but must be the same for - different implementations using the same system. A system will - usually identify a class of operating-systems. Some systems are - defined in - section 10 of this document. - New systems may be defined - by new specifications without revision of this document. -

-
-
implementation defined -
-
-

- The behaviour of the feature may vary from implementation to - implementation, but a particular implementation must document its - behaviour. -

-
-
- -

- - 1.4. Terminology - -

-

- This specification uses many terms defined in the HTTP/1.1 - specification [8]; however, the following terms are - used here in a - sense which may not accord with their definitions in that document, - or with their common meaning. -

- -
-
metavariable -
-
-

- A named parameter that carries information from the server to the - script. It is not necessarily a variable in the operating-system's - environment, although that is the most common implementation. -

-
- -
script -
-
-

- The software which is invoked by the server via this - interface. It - need not be a standalone program, but could be a - dynamically-loaded or shared library, or even a subroutine in the - server. It may be a set of statements - interpreted at run-time, as the term 'script' is frequently - understood, but that is not a requirement and within the context - of this specification the term has the broader definition stated. -

-
-
server -
-
-

- The application program which invokes the script in order to service - requests. -

-
-
- -

- - 2. Notational Conventions and Generic Grammar - -

- -

- - 2.1. Augmented BNF - -

-

- All of the mechanisms specified in this document are described in - both prose and an augmented Backus-Naur Form (BNF) similar to that - used by RFC 822 [6]. This augmented BNF contains - the following constructs: -

-
-
name = definition -
-
-

- The - definition by the equal character ("="). Whitespace is only - significant in that continuation lines of a definition are - indented. -

-
-
"literal" -
-
-

- Quotation marks (") surround literal text, except for a literal - quotation mark, which is surrounded by angle-brackets ("<" and ">"). - Unless stated otherwise, the text is case-sensitive. -

-
-
rule1 | rule2 -
-
-

- Alternative rules are separated by a vertical bar ("|"). -

-
-
(rule1 rule2 rule3) -
-
-

- Elements enclosed in parentheses are treated as a single element. -

-
-
*rule -
-
-

- A rule preceded by an asterisk ("*") may have zero or more - occurrences. A rule preceded by an integer followed by an asterisk - must occur at least the specified number of times. -

-
-
[rule] -
-
-

- An element enclosed in square - brackets ("[" and "]") is optional. -

-
-
- -

- - 2.2. Basic Rules - -

-

- The following rules are used throughout this specification to - describe basic parsing constructs. -

-

- 
-    alpha         = lowalpha | hialpha
-    alphanum      = alpha | digit
-    lowalpha      = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h"
-                    | "i" | "j" | "k" | "l" | "m" | "n" | "o" | "p"
-                    | "q" | "r" | "s" | "t" | "u" | "v" | "w" | "x"
-                    | "y" | "z"
-    hialpha       = "A" | "B" | "C" | "D" | "E" | "F" | "G" | "H"
-                    | "I" | "J" | "K" | "L" | "M" | "N" | "O" | "P"
-                    | "Q" | "R" | "S" | "T" | "U" | "V" | "W" | "X"
-                    | "Y" | "Z"
-    digit         = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7"
-                    | "8" | "9"
-    hex           = digit | "A" | "B" | "C" | "D" | "E" | "F" | "a"
-                    | "b" | "c" | "d" | "e" | "f"
-    escaped       = "%" hex hex
-    OCTET         = <any 8-bit sequence of data>
-    CHAR          = <any US-ASCII character (octets 0 - 127)>
-    CTL           = <any US-ASCII control character
-                    (octets 0 - 31) and DEL (127)>
-    CR            = <US-ASCII CR, carriage return (13)>
-    LF            = <US-ASCII LF, linefeed (10)>
-    SP            = <US-ASCII SP, space (32)>
-    HT            = <US-ASCII HT, horizontal tab (9)>
-    NL            = CR | LF
-    LWSP          = SP | HT | NL
-    tspecial      = "(" | ")" | "@" | "," | ";" | ":" | "\" | <">
-                    | "/" | "[" | "]" | "?" | "<" | ">" | "{" | "}"
-                    | SP | HT | NL
-    token         = 1*<any CHAR except CTLs or tspecials>
-    quoted-string = ( <"> *qdtext <"> ) | ( "<" *qatext ">")
-    qdtext        = <any CHAR except <"> and CTLs but including LWSP>
-    qatext        = <any CHAR except "<", ">" and CTLs but
-                    including LWSP>
-    mark          = "-" | "_" | "." | "!" | "~" | "*" | "'" | "(" | ")"
-    unreserved    = alphanum | mark
-    reserved      = ";" | "/" | "?" | ":" | "@" | "&" | "=" |
-                    "$" | ","
-    uric          = reserved | unreserved | escaped
-
-

- Note that newline (NL) need not be a single character, but can be a - character sequence. -

- -

- - 3. Protocol Parameters - -

- -

- - 3.1. URL Encoding - -

-

- Some variables and constructs used here are described as being - 'URL-encoded'. This encoding is described in section - 2 of RFC - 2396 - [4]. -

-

- An alternate "shortcut" encoding for representing the space - character exists and is in common use. Scripts MUST be prepared to - recognise both '+' and '%20' as an encoded space in a - URL-encoded value. -

-

- Note that some unsafe characters may have different semantics if - they are encoded. The definition of which characters are unsafe - depends on the context. - For example, the following two URLs do not - necessarily refer to the same resource: -

-

- 
-    http://somehost.com/somedir%2Fvalue
-    http://somehost.com/somedir/value
-
-

- See section - 2 of RFC - 2396 [4] - for authoritative treatment of this issue. -

- -

- - 3.2. The Script-URI - -

-

- The 'Script-URI' is defined as the URI of the resource identified - by the metavariables. Often, - this URI will be the same as - the URI requested by the client (the 'Client-URI'); however, it need - not be. Instead, it could be a URI invented by the server, and so it - can only be used in the context of the server and its CGI interface. -

-

- The Script-URI has the syntax of generic-RL as defined in section 2.1 - of RFC 1808 [7], with the exception that object - parameters and - fragment identifiers are not permitted: -

-

- 
-    <scheme>://<host><port>/<path>?<query>
-
-

- The various components of the - Script-URI - are defined by some of the - metavariables (see - section 4 - below); -

-

- 
-    script-uri = protocol "://" SERVER_NAME ":" SERVER_PORT enc-script
-                 enc-path-info "?" QUERY_STRING
-
-

- where 'protocol' is obtained - from SERVER_PROTOCOL, 'enc-script' is a - URL-encoded version of SCRIPT_NAME and 'enc-path-info' is a - URL-encoded version of PATH_INFO. See - section 4.6 for more information about the PATH_INFO - metavariable. -

-

- Note that the scheme and the protocol are not identical; - for instance, a resource accessed via an SSL mechanism - may have a Client-URI with a scheme of "https" - rather than "http". CGI/1.1 provides no means - for the script to reconstruct this, and therefore - the Script-URI includes the base protocol used. -

- -

- - 4. Invoking the Script - -

-

- The - script is invoked in a system defined manner. Unless specified - otherwise, the file containing the script will be invoked as an - executable program. -

- -

- - 5. The CGI Script Command Line - -

-

- Some systems support a method for supplying an array of strings to - the CGI script. This is only used in the case of an 'indexed' query. - This is identified by a "GET" or "HEAD" HTTP request with a URL - query - string not containing any unencoded "=" characters. For such a - request, - servers SHOULD parse the search string - into words, using the following rules: -

-

- 
-    search-string = search-word *( "+" search-word )
-    search-word   = 1*schar
-    schar         = xunreserved | escaped | xreserved
-    xunreserved   = alpha | digit | xsafe | extra
-    xsafe         = "$" | "-" | "_" | "."
-    xreserved     = ";" | "/" | "?" | ":" | "@" | "&"
-
-

- After parsing, each word is URL-decoded, optionally encoded in a - system defined manner, - and then the argument list is set to the list - of words. -

-

- If the server cannot create any part of the argument list, then the - server SHOULD NOT generate any command line information. For example, the - number of arguments may be greater than operating system or server - limitations permit, or one of the words may not be representable as an - argument. -

-

- Scripts SHOULD check to see if the QUERY_STRING value contains an - unencoded "=" character, and SHOULD NOT use the command line arguments - if it does. -

- -

- - 6. Data Input to the CGI Script - -

-

- Information about a request comes from two different sources: the - request header, and any associated - message-body. - Servers MUST - make portions of this information available to - scripts. -

- -

- - 6.1. Request Metadata - (Metavariables) - -

-

- Each CGI server - implementation MUST define a mechanism - to pass data about the request from - the server to the script. - The metavariables containing these - data - are accessed by the script in a system - defined manner. - The - representation of the characters in the - metavariables is - system defined. -

-

- This specification does not distinguish between the representation of - null values and missing ones. Whether null or missing values - (such as a query component of "?" or "", respectively) are represented - by undefined metavariables or by metavariables with values of "" is - implementation-defined. -

-

- Case is not significant in the - metavariable - names, in that there cannot be two - different variables - whose names differ in case only. Here they are - shown using a canonical representation of capitals plus underscore - ("_"). The actual representation of the names is system defined; for - a particular system the representation MAY be defined differently - than this. -

-

- Metavariable - values MUST be - considered case-sensitive except as noted - otherwise. -

-

- The canonical - metavariables - defined by this specification are: -

-

- 
-    AUTH_TYPE
-    CONTENT_LENGTH
-    CONTENT_TYPE
-    GATEWAY_INTERFACE
-    PATH_INFO
-    PATH_TRANSLATED
-    QUERY_STRING
-    REMOTE_ADDR
-    REMOTE_HOST
-    REMOTE_IDENT
-    REMOTE_USER
-    REQUEST_METHOD
-    SCRIPT_NAME
-    SERVER_NAME
-    SERVER_PORT
-    SERVER_PROTOCOL
-    SERVER_SOFTWARE
-
-

- Metavariables with names beginning with the protocol name (e.g., - "HTTP_ACCEPT") are also canonical in their description of request header - fields. The number and meaning of these fields may change independently - of this specification. (See also section 6.1.5.) -

- -

- - 6.1.1. AUTH_TYPE - -

-

- This variable is specific to requests made - via the - "http" - scheme. -

-

- If the Script-URI - required access authentication for external - access, then the server - MUST set - the value of - this variable - from the 'auth-scheme' token in - the request's "Authorization" header - field. - Otherwise - it is - set to NULL. -

-

- 
-    AUTH_TYPE   = "" | auth-scheme
-    auth-scheme = "Basic" | "Digest" | token
-
-

- HTTP access authentication schemes are described in section 11 of the - HTTP/1.1 specification [8]. The auth-scheme is - not case-sensitive. -

-

- Servers - MUST - provide this metavariable - to scripts if the request - header included an "Authorization" field - that was authenticated. -

- -

- - 6.1.2. CONTENT_LENGTH - -

-

- This - metavariable - is set to the - size of the message-body - entity attached to the request, if any, in decimal - number of octets. If no data are attached, then this - metavariable - is either NULL or not - defined. The syntax is - the same as for - the HTTP "Content-Length" header field (section 14.14, HTTP/1.1 - specification [8]). -

-

- 
-    CONTENT_LENGTH = "" | 1*digit
-
-

- Servers MUST provide this metavariable - to scripts if the request - was accompanied by a - message-body entity. -

- -

- - 6.1.3. CONTENT_TYPE - -

-

- If the request includes a - message-body, - CONTENT_TYPE is set - to - the Internet Media Type - [9] of the attached - entity if the type was provided via - a "Content-type" field in the - request header, or if the server can determine it in the absence - of a supplied "Content-type" field. The syntax is the - same as for the HTTP - "Content-Type" header field. -

-

- 
-    CONTENT_TYPE = "" | media-type
-    media-type   = type "/" subtype *( ";" parameter)
-    type         = token
-    subtype      = token
-    parameter    = attribute "=" value
-    attribute    = token
-    value        = token | quoted-string
-
-

- The type, subtype, - and parameter attribute names are not - case-sensitive. Parameter values MAY be case sensitive. - Media types and their use in HTTP are described - in section 3.7 of the - HTTP/1.1 specification [8]. -

-

- Example: -

-

- 
-    application/x-www-form-urlencoded
-
-

- There is no default value for this variable. If and only if it is - unset, then the script MAY attempt to determine the media type from - the data received. If the type remains unknown, then - the script MAY choose to either assume a - content-type of - application/octet-stream - or reject the request with a 415 ("Unsupported Media Type") - error. See section 7.2.1.3 - for more information about returning error status values. -

-

- Servers MUST provide this metavariable - to scripts if - a "Content-Type" field was present - in the original request header. If the server receives a request - with an attached entity but no "Content-Type" - header field, it MAY attempt to - determine the correct datatype, or it MAY omit this - metavariable when - communicating the request information to the script. -

- -

- - 6.1.4. GATEWAY_INTERFACE - -

-

- This - metavariable - is set to - the dialect of CGI being used - by the server to communicate with the script. - Syntax: -

-

- 
-    GATEWAY_INTERFACE = "CGI" "/" major "." minor
-    major             = 1*digit
-    minor             = 1*digit
-
-

- Note that the major and minor numbers are treated as separate - integers and hence each may be - more than a single - digit. Thus CGI/2.4 is a lower version than CGI/2.13 which in turn - is lower than CGI/12.3. Leading zeros in either - the major or the minor number MUST be ignored by scripts and - SHOULD NOT be generated by servers. -

-

- This document defines the 1.1 version of the CGI interface - ("CGI/1.1"). -

-

- Servers MUST provide this metavariable - to scripts. -

- -

- - 6.1.5. Protocol-Specific Metavariables - -

-

- These metavariables are specific to - the protocol - via which the request is made. - Interpretation of these variables depends on the value of - the - SERVER_PROTOCOL - metavariable - (see - section 6.1.17). -

-

- Metavariables - with names beginning with "HTTP_" contain - values from the request header, if the - scheme used was HTTP. - Each - HTTP header field name is converted to upper case, has all occurrences of - "-" replaced with "_", - and has "HTTP_" prepended to form - the metavariable name. - Similar transformations are applied for other - protocols. - The header data MAY be presented as sent - by the client, or MAY be rewritten in ways which do not change its - semantics. If multiple header fields with the same field-name are received - then the server - MUST rewrite them as though they - had been received as a single header field having the same - semantics before being represented in a - metavariable. - Similarly, a header field that is received on more than one line - MUST be merged into a single line. The server MUST, if necessary, - change the representation of the data (for example, the character - set) to be appropriate for a CGI - metavariable. - -

-

- Servers are - not required to create - metavariables for all - the request - header fields that they - receive. In particular, - they MAY - decline to make available any - header fields carrying authentication information, such as - "Authorization", or - which are available to the script - via other metavariables, - such as "Content-Length" and "Content-Type". -

- -

- - 6.1.6. PATH_INFO - -

-

- The PATH_INFO - metavariable - specifies - a path to be interpreted by the CGI script. It identifies the - resource or sub-resource to be returned - by the CGI - script, and it is derived from the portion - of the URI path following the script name but preceding - any query data. - The syntax - and semantics are similar to a decoded HTTP URL - 'path' token - (defined in - RFC 2396 - [4]), with the exception - that a PATH_INFO of "/" - represents a single void path segment. -

-

- 
-    PATH_INFO = "" | ( "/" path )
-    path      = segment *( "/" segment )
-    segment   = *pchar
-    pchar     = <any CHAR except "/">
-
-

- The PATH_INFO string is the trailing part of the <path> component of - the Script-URI - (see section 3.2) - that follows the SCRIPT_NAME - portion of the path. -

-

- Servers MAY impose their own restrictions and - limitations on what values they will accept for PATH_INFO, and MAY - reject or edit any values they - consider objectionable before passing - them to the script. -

-

- Servers MUST make this URI component available - to CGI scripts. The PATH_INFO - value is case-sensitive, and the - server MUST preserve the case of the PATH_INFO element of the URI - when making it available to scripts. -

- -

- - 6.1.7. PATH_TRANSLATED - -

-

- PATH_TRANSLATED is derived by taking any path-info component of the - request URI (see - section 6.1.6), decoding it - (see section 3.1), parsing it as a URI in its own - right, and performing any virtual-to-physical - translation appropriate to map it onto the - server's document repository structure. - If the request URI includes no path-info - component, the PATH_TRANSLATED metavariable SHOULD NOT be defined. -

-

- 
-    PATH_TRANSLATED = *CHAR
-
-

- For a request such as the following: -

-

- 
-    http://somehost.com/cgi-bin/somescript/this%2eis%2epath%2einfo
-
-

- the PATH_INFO component would be decoded, and the result - parsed as though it were a request for the following: -

-

- 
-    http://somehost.com/this.is.the.path.info
-
-

- This would then be translated to a - location in the server's document repository, - perhaps a filesystem path something - like this: -

-

- 
-    /usr/local/www/htdocs/this.is.the.path.info
-
-

- The result of the translation is the value of PATH_TRANSLATED. -

-

- The value of PATH_TRANSLATED may or may not map to a valid - repository - location. - Servers MUST preserve the case of the path-info - segment if and only if the underlying - repository - supports case-sensitive - names. If the - repository - is only case-aware, case-preserving, or case-blind - with regard to - document names, - servers are not required to preserve the - case of the original segment through the translation. -

-

- The - translation - algorithm the server uses to derive PATH_TRANSLATED is - implementation defined; CGI scripts which use this variable may - suffer limited portability. -

-

- Servers SHOULD provide this metavariable - to scripts if and only if the request URI includes a - path-info component. -

- -

- - 6.1.8. QUERY_STRING - -

-

- A URL-encoded - string; the <query> part of the - Script-URI. - (See - section 3.2.) -

-

- 
-    QUERY_STRING = query-string
-    query-string = *uric
-
-

- The URL syntax for a query - string is described in - section 3 of - RFC 2396 - [4]. -

-

- Servers MUST supply this value to scripts. - The QUERY_STRING value is case-sensitive. - If the Script-URI does not include a query component, - the QUERY_STRING metavariable MUST be defined as an empty string (""). -

- -

- - 6.1.9. REMOTE_ADDR - -

-

- The IP address of the client - sending the request to the server. This - is not necessarily that of the user - agent - (such as if the request came through a proxy). -

-

- 
-    REMOTE_ADDR  = hostnumber
-    hostnumber   = ipv4-address | ipv6-address
-
-

- The definitions of ipv4-address and ipv6-address - are provided in Appendix B of RFC 2373 [13]. -

-

- Servers MUST supply this value to scripts. -

- -

- - 6.1.10. REMOTE_HOST - -

-

- The fully qualified domain name of the - client sending the request to - the server, if available, otherwise NULL. - (See section 6.1.9.) - Fully qualified domain names take the form as described in - section 3.5 of RFC 1034 [10] and section 2.1 of - RFC 1123 [5]. Domain names are not case sensitive. -

-

- Servers SHOULD provide this information to - scripts. -

- -

- - 6.1.11. REMOTE_IDENT - -

-

- The identity information reported about the connection by a - RFC 1413 [11] request to the remote agent, if - available. Servers - MAY choose not - to support this feature, or not to request the data - for efficiency reasons. -

-

- 
-    REMOTE_IDENT = *CHAR
-
-

- The data returned - may be used for authentication purposes, but the level - of trust reposed in them should be minimal. -

-

- Servers MAY supply this information to scripts if the - RFC1413 [11] lookup is performed. -

- -

- - 6.1.12. REMOTE_USER - -

-

- If the request required authentication using the "Basic" - mechanism (i.e., the AUTH_TYPE - metavariable is set - to "Basic"), then the value of the REMOTE_USER - metavariable is set to the - user-ID supplied. In all other cases - the value of this metavariable - is undefined. -

-

- 
-    REMOTE_USER = *OCTET
-
-

- This variable is specific to requests made via the - HTTP protocol. -

-

- Servers SHOULD provide this metavariable - to scripts. -

- -

- - 6.1.13. REQUEST_METHOD - -

-

- The REQUEST_METHOD - metavariable - is set to the - method with which the request was made, as described in section - 5.1.1 of the HTTP/1.0 specification [3] and - section 5.1.1 of the - HTTP/1.1 specification [8]. -

-

- 
-    REQUEST_METHOD   = http-method
-    http-method      = "GET" | "HEAD" | "POST" | "PUT" | "DELETE"
-                       | "OPTIONS" | "TRACE" | extension-method
-    extension-method = token
-
-

- The method is case sensitive. - CGI/1.1 servers MAY choose to process some methods - directly rather than passing them to scripts. -

-

- This variable is specific to requests made with HTTP. -

-

- Servers MUST provide this metavariable - to scripts. -

- -

- - 6.1.14. SCRIPT_NAME - -

-

- The SCRIPT_NAME - metavariable - is - set to a URL path that could identify the CGI script (rather than the - script's - output). The syntax and semantics are identical to a - decoded HTTP URL 'path' token - (see RFC 2396 - [4]). -

-

- 
-    SCRIPT_NAME = "" | ( "/" [ path ] )
-
-

- The SCRIPT_NAME string is some leading part of the <path> component - of the Script-URI derived in some - implementation defined manner. - No PATH_INFO or QUERY_STRING segments - (see sections 6.1.6 and - 6.1.8) are included - in the SCRIPT_NAME value. -

-

- Servers MUST provide this metavariable - to scripts. -

- -

- - 6.1.15. SERVER_NAME - -

-

- The SERVER_NAME - metavariable - is set to the - name of the - server, as - derived from the <host> part of the - Script-URI - (see section 3.2). -

-

- 
-    SERVER_NAME = hostname | hostnumber
-
-

- Servers MUST provide this metavariable - to scripts. -

- -

- - 6.1.16. SERVER_PORT - -

-

- The SERVER_PORT - metavariable - is set to the - port on which the - request was received, as used in the <port> - part of the Script-URI. -

-

- 
-    SERVER_PORT = 1*digit
-
-

- If the <port> portion of the script-URI is blank, the actual - port number upon which the request was received MUST be supplied. -

-

- Servers MUST provide this metavariable - to scripts. -

- -

- - 6.1.17. SERVER_PROTOCOL - -

-

- The SERVER_PROTOCOL - metavariable - is set to - the - name and revision of the information protocol with which - the - request - arrived. This is not necessarily the same as the protocol version used by - the server in its response to the client. -

-

- 
-    SERVER_PROTOCOL   = HTTP-Version | extension-version
-                        | extension-token
-    HTTP-Version      = "HTTP" "/" 1*digit "." 1*digit
-    extension-version = protocol "/" 1*digit "." 1*digit
-    protocol          = 1*( alpha | digit | "+" | "-" | "." )
-    extension-token   = token
-
-

- 'protocol' is a version of the <scheme> part of the - Script-URI, but is - not identical to it. For example, the scheme of a request may be - "https" while the protocol remains "http". - The protocol is not case sensitive, but - by convention, 'protocol' is in - upper case. -

-

- A well-known extension token value is "INCLUDED", - which signals that the current document is being included as part of - a composite document, rather than being the direct target of the - client request. -

-

- Servers MUST provide this metavariable - to scripts. -

- -

- - 6.1.18. SERVER_SOFTWARE - -

-

- The SERVER_SOFTWARE - metavariable - is set to the - name and version of the information server software answering the - request (and running the gateway). -

-

- 
-    SERVER_SOFTWARE = 1*product
-    product         = token [ "/" product-version ]
-    product-version = token
-
-

- Servers MUST provide this metavariable - to scripts. -

- -

- - 6.2. Request Message-Bodies - -

-

- As there may be a data entity attached to the request, there MUST be - a system defined method for the script to read - these data. Unless - defined otherwise, this will be via the 'standard input' file - descriptor. -

-

- If the CONTENT_LENGTH value (see section 6.1.2) - is non-NULL, the server MUST supply at least that many bytes to - scripts on the standard input stream. - Scripts are - not obliged to read the data. - Servers MAY signal an EOF condition after CONTENT_LENGTH bytes have been - read, but are - not obligated to do so. Therefore, scripts - MUST NOT - attempt to read more than CONTENT_LENGTH bytes, even if more data - are available. -

-

- For non-parsed header (NPH) scripts (see - section 7.1 - below), - servers SHOULD - attempt to ensure that the data - supplied to the script are precisely - as supplied by the client and unaltered by - the server. -

-

- Section 8.1.2 describes the requirements of - servers with regard to requests that include - message-bodies. -

- -

- - 7. Data Output from the CGI Script - -

-

- There MUST be a system defined method for the script to send data - back to the server or client; a script MUST always return some data. - Unless defined otherwise, this will be via the 'standard - output' file descriptor. -

-

- There are two forms of output that scripts can supply to servers: non-parsed - header (NPH) output, and parsed header output. - Servers MUST support parsed header - output and MAY support NPH output. The method of - distinguishing between the two - types of output (or scripts) is implementation defined. -

-

- Servers MAY implement a timeout period within which data must be - received from scripts. If a server implementation defines such - a timeout and receives no data from a script within the timeout - period, the server MAY terminate the script process and SHOULD - abort the client request with - either a - '504 Gateway Timed Out' or a - '500 Internal Server Error' response. -

- -

- - 7.1. Non-Parsed Header Output - -

-

- Scripts using the NPH output form - MUST return a complete HTTP response message, as described - in Section 6 of the HTTP specifications - [3,8]. - NPH scripts - MUST use the SERVER_PROTOCOL variable to determine the appropriate format - for a response. -

-

- Servers - SHOULD attempt to ensure that the script output is sent - directly to the client, with minimal - internal and no transport-visible - buffering. -

- -

- - 7.2. Parsed Header Output - -

-

- Scripts using the parsed header output form MUST supply - a CGI response message to the server - as follows: -

-

- 
-    CGI-Response   = *optional-field CGI-Field *optional-field NL [ Message-Body ]
-    optional-field = ( CGI-Field | HTTP-Field )
-    CGI-Field      = Content-type
-                   | Location
-                   | Status
-                   | extension-header
-
-

- The response comprises a header and a body, separated by a blank line. - The body may be NULL. - The header fields are either CGI header fields to be interpreted by - the server, or HTTP header fields - to be included in the response returned - to the client - if the request method is HTTP. At least one - CGI-Field MUST be - supplied, but no CGI field name may be used more than once - in a response. - If a body is supplied, then a "Content-type" - header field MUST be - supplied by the script, - otherwise the script MUST send a "Location" - or "Status" header field. If a - Location CGI-Field - is returned, then the script MUST NOT supply - any HTTP-Fields. -

-

- Each header field in a CGI-Response MUST be specified on a single line; - CGI/1.1 does not support continuation lines. -

- -

- - 7.2.1. CGI header fields - -

-

- The CGI header fields have the generic syntax: -

-

- 
-    generic-field  = field-name ":" [ field-value ] NL
-    field-name     = token
-    field-value    = *( field-content | LWSP )
-    field-content  = *( token | tspecial | quoted-string )
-
-

- The field-name is not case sensitive; a NULL field value is - equivalent to the header field not being sent. -

- -

- - 7.2.1.1. Content-Type - -

-

- The Internet Media Type [9] of the entity - body, which is to be sent unmodified to the client. -

-

- 
-    Content-Type = "Content-Type" ":" media-type NL
-
-

- This is actually an HTTP-Field - rather than a CGI-Field, but - it is listed here because of its importance in the CGI dialogue as - a member of the "one of these is required" set of header - fields. -

- -

- - 7.2.1.2. Location - -

-

- This is used to specify to the server that the script is returning a - reference to a document rather than an actual document. -

-

- 
-    Location         = "Location" ":"
-                       ( fragment-URI | rel-URL-abs-path ) NL
-    fragment-URI     = URI [ # fragmentid ]
-    URI              = scheme ":" *qchar
-    fragmentid       = *qchar
-    rel-URL-abs-path = "/" [ hpath ] [ "?" query-string ]
-    hpath            = fpsegment *( "/" psegment )
-    fpsegment        = 1*hchar
-    psegment         = *hchar
-    hchar            = alpha | digit | safe | extra
-                       | ":" | "@" | "& | "="
-
-

- The Location - value is either an absolute URI with optional fragment, - as defined in RFC 1630 [1], or an absolute path - within the server's URI space (i.e., - omitting the scheme and network-related fields) and optional - query-string. If an absolute URI is returned by the script, - then the - server MUST generate a - '302 redirect' HTTP response - message unless the script has supplied an - explicit Status response header field. - Scripts returning an absolute URI MAY choose to - provide a message-body. Servers MUST make any appropriate modifications - to the script's output to ensure the response to the user-agent complies - with the response protocol version. - If the Location value is a path, then the server - MUST generate - the response that it would have produced in response to a request - containing the URL -

-

- 
-    scheme "://" SERVER_NAME ":" SERVER_PORT rel-URL-abs-path
-
-

- Note: If the request was accompanied by a - message-body - (such as for a POST request), and the script - redirects the request with a Location field, the - message-body - may not be - available to the resource that is the target of the redirect. -

- -

- - 7.2.1.3. Status - -

-

- The "Status" header field is used to indicate to the server what - status code the server MUST use in the response message. -

-

- 
-    Status        = "Status" ":" digit digit digit SP reason-phrase NL
-    reason-phrase = *<CHAR, excluding CTLs, NL>
-
-

- The valid status codes are listed in section 6.1.1 of the HTTP/1.0 - specifications [3]. If the SERVER_PROTOCOL is - "HTTP/1.1", then the status codes defined in the HTTP/1.1 - specification [8] may - be used. If the script does not return a "Status" header - field, then "200 OK" SHOULD be assumed by the server. -

-

- If a script is being used to handle a particular error or condition - encountered by the server, such as a '404 Not Found' error, the script - SHOULD use the "Status" CGI header field to propagate the error - condition back to the client. E.g., in the example mentioned it - SHOULD include a "Status: 404 Not Found" in the - header data returned to the server. -

- -

- - 7.2.1.4. Extension header fields - -

-

- Scripts MAY include in their CGI response header additional fields - not defined in this or the HTTP specification. - These are called "extension" fields, - and have the syntax of a generic-field as defined in - section 7.2.1. The name of an extension field - MUST NOT conflict with a field name defined in this or any other - specification; extension field names SHOULD begin with "X-CGI-" - to ensure uniqueness. -

- -

- - 7.2.2. HTTP header fields - -

-

- The script MAY return any other header fields defined by the - specification - for the SERVER_PROTOCOL (HTTP/1.0 [3] or HTTP/1.1 - [8]). - Servers MUST resolve conflicts beteen CGI header - and HTTP header formats or names (see section 8). -

- -

- - 8. Server Implementation - -

-

- This section defines the requirements that must be met by HTTP - servers in order to provide a coherent and correct CGI/1.1 - environment in which scripts may function. It is intended - primarily for server implementors, but it is useful for - script authors to be familiar with the information as well. -

- -

- - 8.1. Requirements for Servers - -

-

- In order to be considered CGI/1.1-compliant, a server must meet - certain basic criteria and provide certain minimal functionality. - The details of these requirements are described in the following sections. -

- -

- - 8.1.1. Script-URI - -

-

- Servers MUST support the standard mechanism (described below) which - allows - script authors to determine - what URL to use in documents - which reference the script; - specifically, what URL to use in order to - achieve particular settings of the - metavariables. This - mechanism is as follows: -

-

- The server - MUST translate the header data from the CGI header field syntax to - the HTTP - header field syntax if these differ. For example, the character - sequence for - newline (such as Unix's ASCII NL) used by CGI scripts may not be the - same as that used by HTTP (ASCII CR followed by LF). The server MUST - also resolve any conflicts between header fields returned by the script - and header fields that it would otherwise send itself. -

- -

- - 8.1.2. Request Message-body Handling - -

-

- These are the requirements for server handling of message-bodies directed - to CGI/1.1 resources: -

-
    -
  1. The message-body the server provides to the CGI script MUST - have any transfer encodings removed. -
    2. -
  2. The server MUST derive and provide a value for the CONTENT_LENGTH - metavariable that reflects the length of the message-body after any - transfer decoding. -
    3. -
  3. The server MUST leave intact any content-encodings of the message-body. -
    4. -
- -

- - 8.1.3. Required Metavariables - -

-

- Servers MUST provide scripts with certain information and - metavariables - as described in section 8.3. -

- -

- - 8.1.4. Response Compliance - -

-

- Servers MUST ensure that responses sent to the user-agent meet all - requirements of the protocol level in effect. This may involve - modifying, deleting, or augmenting any header - fields and/or message-body supplied by the script. -

- -

- - 8.2. Recommendations for Servers - -

-

- Servers SHOULD provide the "query" component of the script-URI - as command-line arguments to scripts if it does not - contain any unencoded '=' characters and the command-line arguments can - be generated in an unambiguous manner. - (See section 5.) -

-

- Servers SHOULD set the AUTH_TYPE - metavariable to the value of the - 'auth-scheme' token of the "Authorization" - field if it was supplied as part of the request header. - (See section 6.1.1.) -

-

- Where applicable, servers SHOULD set the current working directory - to the directory in which the script is located before invoking - it. -

-

- Servers MAY reject with error '404 Not Found' - any requests that would result in - an encoded "/" being decoded into PATH_INFO or SCRIPT_NAME, as this - might represent a loss of information to the script. -

-

- Although the server and the CGI script need not be consistent in - their handling of URL paths (client URLs and the PATH_INFO data, - respectively), server authors may wish to impose consistency. - So the server implementation SHOULD define its behaviour for the - following cases: -

-
    -
  1. define any restrictions on allowed characters, in particular - whether ASCII NUL is permitted; -
    2. -
  2. define any restrictions on allowed path segments, in particular - whether non-terminal NULL segments are permitted; -
    3. -
  3. define the behaviour for "." or ".." path - segments; i.e., whether they are prohibited, treated as - ordinary path - segments or interpreted in accordance with the relative URL - specification [7]; -
    4. -
  4. define any limits of the implementation, including limits on path or - search string lengths, and limits on the volume of header data the server - will parse. -
    5. -
-

- Servers MAY generate the - Script-URI in - any way from the client URI, - or from any other data (but the behaviour SHOULD be documented). -

-

- For non-parsed header (NPH) scripts (see - section 7.1), servers SHOULD - attempt to ensure that the script input comes directly from the - client, with minimal buffering. For all scripts the data will be - as supplied by the client. -

- -

- - 8.3. Summary of - MetaVariables - -

-

- Servers MUST provide the following - metavariables to - scripts. See the individual descriptions for exceptions and semantics. -

-

- 
-    CONTENT_LENGTH (section 6.1.2)
-    CONTENT_TYPE (section 6.1.3)
-    GATEWAY_INTERFACE (section 6.1.4)
-    PATH_INFO (section 6.1.6)
-    QUERY_STRING (section 6.1.8)
-    REMOTE_ADDR (section 6.1.9)
-    REQUEST_METHOD (section 6.1.13)
-    SCRIPT_NAME (section 6.1.14)
-    SERVER_NAME (section 6.1.15)
-    SERVER_PORT (section 6.1.16)
-    SERVER_PROTOCOL (section 6.1.17)
-    SERVER_SOFTWARE (section 6.1.18)
-
-

- Servers SHOULD define the following - metavariables for scripts. - See the individual descriptions for exceptions and semantics. -

-

- 
-    AUTH_TYPE (section 6.1.1)
-    REMOTE_HOST (section 6.1.10)
-
-

- In addition, servers SHOULD provide - metavariables for all fields present - in the HTTP request header, with the exception of those involved with - access control. Servers MAY at their discretion provide - metavariables - for access control fields. -

-

- Servers MAY define the following - metavariables. See the individual - descriptions for exceptions and semantics. -

-

- 
-    PATH_TRANSLATED (section 6.1.7)
-    REMOTE_IDENT (section 6.1.11)
-    REMOTE_USER (section 6.1.12)
-
-

- Servers MAY - at their discretion define additional implementation-specific - extension metavariables - provided their names do not - conflict with defined header field names. Implementation-specific - metavariable names SHOULD - be prefixed with "X_" (e.g., - "X_DBA") to avoid the potential for such conflicts. -

- -

- - 9. - Script Implementation - -

-

- This section defines the requirements and recommendations for scripts - that are intended to function in a CGI/1.1 environment. It is intended - primarily as a reference for script authors, but server implementors - should be familiar with these issues as well. -

- -

- - 9.1. Requirements for Scripts - -

-

- Scripts using the parsed-header method to communicate with servers - MUST supply a response header to the server. - (See section 7.) -

-

- Scripts using the NPH method to communicate with servers MUST - provide complete HTTP responses, and MUST use the value of the - SERVER_PROTOCOL metavariable - to determine the appropriate format. - (See section 7.1.) -

-

- Scripts MUST check the value of the REQUEST_METHOD - metavariable in order - to provide an appropriate response. - (See section 6.1.13.) -

-

- Scripts MUST be prepared to handled URL-encoded values in - metavariables. - In addition, they MUST recognise both "+" and "%20" in URL-encoded - quantities as representing the space character. - (See section 3.1.) -

-

- Scripts MUST ignore leading zeros in the major and minor version numbers - in the GATEWAY_INTERFACE - metavariable value. (See - section 6.1.4.) -

-

- When processing requests that include a - message-body, scripts - MUST NOT read more than CONTENT_LENGTH bytes from the input stream. - (See sections 6.1.2 and 6.2.) -

- -

- - 9.2. Recommendations for Scripts - -

-

- Servers may interrupt or terminate script execution at any time - and without warning, so scripts SHOULD be prepared to deal with - abnormal termination. -

-

- Scripts MUST - reject with - error '405 Method Not - Allowed' requests - made using methods that they do not support. If the script does - not intend - processing the PATH_INFO data, then it SHOULD reject the request with - '404 Not - Found' if PATH_INFO is not NULL. -

-

- If a script is processing the output of a form, it SHOULD - verify that the CONTENT_TYPE - is "application/x-www-form-urlencoded" [2] - or whatever other media type is expected. -

-

- Scripts parsing PATH_INFO, - PATH_TRANSLATED, or SCRIPT_NAME - SHOULD be careful - of void path segments ("//") and special path segments - ("." and - ".."). They SHOULD either be removed from the path before - use in OS - system calls, or the request SHOULD be rejected with - '404 Not Found'. -

-

- As it is impossible for - scripts to determine the client URI that - initiated a - request without knowledge of the specific server in - use, the script SHOULD NOT return "text/html" - documents containing - relative URL links without including a "<BASE>" - tag in the document. -

-

- When returning header fields, - scripts SHOULD try to send the CGI - header fields (see section - 7.2) as soon as possible, and - SHOULD send them - before any HTTP header fields. This may - help reduce the server's memory requirements. -

- -

- - 10. System Specifications - -

- -

- - 10.1. AmigaDOS - -

-

- The implementation of the CGI on an AmigaDOS operating system platform - SHOULD use environment variables as the mechanism of providing - request metadata to CGI scripts. -

-
-
Environment variables -
-
-

- These are accessed by the DOS library routine GetVar. The - flags argument SHOULD be 0. Case is ignored, but upper case is - recommended for compatibility with case-sensitive systems. -

-
-
The current working directory -
-
-

- The current working directory for the script is set to the directory - containing the script. -

-
-
Character set -
-
-

- The US-ASCII character set is used for the definition of environment - variable names and header - field names; the newline (NL) sequence is LF; - servers SHOULD also accept CR LF as a newline. -

-
-
- -

- - 10.2. Unix - -

-

- The implementation of the CGI on a UNIX operating system platform - SHOULD use environment variables as the mechanism of providing - request metadata to CGI scripts. -

-

- For Unix compatible operating systems, the following are defined: -

-
-
Environment variables -
-
-

- These are accessed by the C library routine getenv. -

-
-
The command line -
-
-

- This is accessed using the - argc and argv - arguments to main(). The words have any characters - that - are 'active' in the Bourne shell escaped with a backslash. - If the value of the QUERY_STRING - metavariable - contains an unencoded equals-sign '=', then the command line - SHOULD NOT be used by the script. -

-
-
The current working directory -
-
-

- The current working directory for the script - SHOULD be set to the directory - containing the script. -

-
-
Character set -
-
-

- The US-ASCII character set is used for the definition of environment - variable names and header field names; the newline (NL) sequence is LF; - servers SHOULD also accept CR LF as a newline. -

-
-
- -

- - 11. Security Considerations - -

- -

- - 11.1. Safe Methods - -

-

- As discussed in the security considerations of the HTTP - specifications [3,8], the - convention has been established that the - GET and HEAD methods should be 'safe'; they should cause no - side-effects and only have the significance of resource retrieval. -

-

- CGI scripts are responsible for enforcing any HTTP security considerations - [3,8] - with respect to the protocol version level of the request and - any side effects generated by the scripts on behalf of - the server. Primary - among these - are the considerations of safe and idempotent methods. Idempotent - requests are those that may be repeated an arbitrary number of times - and produce side effects identical to a single request. -

- -

- - 11.2. HTTP Header - Fields Containing Sensitive Information - -

-

- Some HTTP header fields may carry sensitive information which the server - SHOULD NOT pass on to the script unless explicitly configured to do - so. For example, if the server protects the script using the - "Basic" - authentication scheme, then the client will send an - "Authorization" - header field containing a username and password. If the server, rather - than the script, validates this information then the password SHOULD - NOT be passed on to the script via the HTTP_AUTHORIZATION - metavariable - without careful consideration. - This also applies to the - Proxy-Authorization header field and the corresponding - HTTP_PROXY_AUTHORIZATION - metavariable. -

- -

- - 11.3. Script - Interference with the Server - -

-

- The most common implementation of CGI invokes the script as a child - process using the same user and group as the server process. It - SHOULD therefore be ensured that the script cannot interfere with the - server process, its configuration, or documents. -

-

- If the script is executed by calling a function linked in to the - server software (either at compile-time or run-time) then precautions - SHOULD be taken to protect the core memory of the server, or to - ensure that untrusted code cannot be executed. -

- -

- - 11.4. Data Length and Buffering Considerations - -

-

- This specification places no limits on the length of message-bodies - presented to the script. Scripts should not assume that statically - allocated buffers of any size are sufficient to contain the entire - submission at one time. Use of a fixed length buffer without careful - overflow checking may result in an attacker exploiting 'stack-smashing' - or 'stack-overflow' vulnerabilities of the operating system. - Scripts may spool large submissions to disk or other buffering media, - but a rapid succession of large submissions may result in denial of - service conditions. If the CONTENT_LENGTH of a message-body is larger - than resource considerations allow, scripts should respond with an - error status appropriate for the protocol version; potentially applicable - status codes include '503 Service Unavailable' (HTTP/1.0 and HTTP/1.1), - '413 Request Entity Too Large' (HTTP/1.1), and - '414 Request-URI Too Long' (HTTP/1.1). -

- -

- - 11.5. Stateless Processing - -

-

- The stateless nature of the Web makes each script execution and resource - retrieval independent of all others even when multiple requests constitute a - single conceptual Web transaction. Because of this, a script should not - make any assumptions about the context of the user-agent submitting a - request. In particular, scripts should examine data obtained from the client - and verify that they are valid, both in form and content, before allowing - them to be used for sensitive purposes such as input to other - applications, commands, or operating system services. These uses - include, but are not - limited to: system call arguments, database writes, dynamically evaluated - source code, and input to billing or other secure processes. It is important - that applications be protected from invalid input regardless of whether - the invalidity is the result of user error, logic error, or malicious action. -

-

- Authors of scripts involved in multi-request transactions should be - particularly cautios about validating the state information; - undesirable effects may result from the substitution of dangerous - values for portions of the submission which might otherwise be - presumed safe. Subversion of this type occurs when alterations - are made to data from a prior stage of the transaction that were - not meant to be controlled by the client (e.g., hidden - HTML form elements, cookies, embedded URLs, etc.). -

For -everyone else, mdev is a weird black box that they hear is awesome, but can't -seem to get their head around how it works. Thus, a primer. - ------------ - Basic Use ------------ - -Mdev has two primary uses: initial population and dynamic updates. Both -require sysfs support in the kernel and have it mounted at /sys. For dynamic -updates, you also need to have hotplugging enabled in your kernel. - -Here's a typical code snippet from the init script: -[0] mount -t proc proc /proc -[1] mount -t sysfs sysfs /sys -[2] echo /sbin/mdev > /proc/sys/kernel/hotplug -[3] mdev -s - -Alternatively, without procfs the above becomes: -[1] mount -t sysfs sysfs /sys -[2] sysctl -w kernel.hotplug=/sbin/mdev -[3] mdev -s - - -Of course, a more "full" setup would entail executing this before the previous -code snippet: -[4] mount -t tmpfs -o size=64k,mode=0755 tmpfs /dev -[5] mkdir /dev/pts -[6] mount -t devpts devpts /dev/pts - -The simple explanation here is that [1] you need to have /sys mounted before -executing mdev. Then you [2] instruct the kernel to execute /sbin/mdev whenever -a device is added or removed so that the device node can be created or -destroyed. Then you [3] seed /dev with all the device nodes that were created -while the system was booting. - -For the "full" setup, you want to [4] make sure /dev is a tmpfs filesystem -(assuming you're running out of flash). Then you want to [5] create the -/dev/pts mount point and finally [6] mount the devpts filesystem on it. - -------------- - MDEV Config (/etc/mdev.conf) -------------- - -Mdev has an optional config file for controlling ownership/permissions of -device nodes if your system needs something more than the default root/root -660 permissions. - -The file has the format: - [-] : -or - @ : -or - $envvar= : - -For example: - hd[a-z][0-9]* 0:3 660 - -The config file parsing stops at the first matching line. If no line is -matched, then the default of 0:0 660 is used.

If you want to rename the device node, just place the name. - hda 0:3 660 =drives/ -This will move "hda" into the drives/ subdirectory. - hdb 0:3 660 =cdrom -This will rename "hdb" to "cdrom". - -Similarly, ">path" renames/moves the device but it also creates -a direct symlink /dev/DEVNAME to the renamed/moved device. - -You can also prevent creation of device nodes with the 4th field as "!": - tty[a-z]. 0:0 660 ! - pty[a-z]. 0:0 660 ! - -If you also enable support for executing your own commands, then the file has -the format: - : [=path] [@|$|*] - or - : [>path] [@|$|*] - or - : [!] [@|$|*] - -For example: ----8<--- -# block devices -([hs]d[a-z]) root:disk 660 >disk/%1/0 -([hs]d[a-z])([0-9]+) root:disk 660 >disk/%1/%2 -mmcblk([0-9]+) root:disk 660 >disk/mmc/%1/0 -mmcblk([0-9]+)p([0-9]+) root:disk 660 >disk/mmc/%1/%2 -# network devices -(tun|tap) root:network 660 >net/%1 ----8<--- - -The special characters have the meaning: - @ Run after creating the device. - $ Run before removing the device. - * Run both after creating and before removing the device. - -The command is executed via the system() function (which means you're giving a -command to the shell), so make sure you have a shell installed at /bin/sh. You -should also keep in mind that the kernel executes hotplug helpers with stdin, -stdout, and stderr connected to /dev/null. - -For your convenience, the shell env var $MDEV is set to the device name. So if -the device "hdc" was matched, MDEV would be set to "hdc". - ----------- - FIRMWARE ----------- - -Some kernel device drivers need to request firmware at runtime in order to -properly initialize a device. Place all such firmware files into the -/lib/firmware/ directory. At runtime, the kernel will invoke mdev with the -filename of the firmware which mdev will load out of /lib/firmware/ and into -the kernel via the sysfs interface. The exact filename is hardcoded in the -kernel, so look there if you need to know how to name the file in userspace. - ------------- - SEQUENCING ------------- - -Kernel does not serialize hotplug events. It increments SEQNUM environmental -variable for each successive hotplug invocation. Normally, mdev doesn't care. -This may reorder hotplug and hot-unplug events, with typical symptoms of -device nodes sometimes not created as expected. - -However, if /dev/mdev.seq file is found, mdev will compare its -contents with SEQNUM. It will retry up to two seconds, waiting for them -to match. If they match exactly (not even trailing '\n' is allowed), -or if two seconds pass, mdev runs as usual, then it rewrites /dev/mdev.seq -with SEQNUM+1. - -IOW: this will serialize concurrent mdev invocations. - -If you want to activate this feature, execute "echo >/dev/mdev.seq" prior to -setting mdev to be the hotplug handler. This writes single '\n' to the file. -NB: mdev recognizes /dev/mdev.seq consisting of single '\n' character -as a special case.

Proper handling of SIGINT/SIGQUIT

- -

- - - - - -
Abstract: -In UNIX terminal sessions, you usually have a key like -C-c (Control-C) to immediately end whatever program you -have running in the foreground. This should work even when the program -you called has called other programs in turn. Everything should be -aborted, giving you your command prompt back, no matter how deep the -call stack is. - -

Basically, it's trivial. But the existence of interactive -applications that use SIGINT and/or SIGQUIT for other purposes than a -complete immediate abort make matters complicated, and - as was to -expect - left us with several ways to solve the problems. Of course, -existing shells and applications follow different ways. - -

This Web pages outlines different ways to solve the problem and -argues that only one of them can do everything right, although it -means that we have to fix some existing software. - - - -

Intended audience: Programmers who implement programs that catch SIGINT/SIGQUIT. -
Programmers who implements shells or shell-like programs that -execute batches of programs. - -

Users who have problems problems getting rid of runaway shell -scripts using Control-C. Or have interactive applications -that don't behave right when sending SIGINT. Examples are emacs'es -that die on Control-g or shellscript statements that sometimes are -executed and sometimes not, apparently not determined by the user's -intention. - - -

Required knowledge: You have to know what it means to catch SIGINT or SIGQUIT and how -processes are waiting for other processes (childs) they spawned. - - -
- - - -

Basic concepts

- -What technically happens when you press Control-C is that all programs -running in the foreground in your current terminal (or virtual -terminal) get the signal SIGINT sent. - -

You may change the key that triggers the signal using -stty and running programs may remap the SIGINT-sending -key at any time they like, without your intervention and without -asking you first. - -

The usual reaction of a running program to SIGINT is to exit. -However, not all program do an exit on SIGINT, programs are free to -use the signal for other actions or to ignore it at all. - -

All programs running in the foreground receive the signal. This may -be a nested "stack" of programs: You started a program that started -another and the outer is waiting for the inner to exit. This nesting -may be arbitrarily deep. - -

The innermost program is the one that decides what to do on SIGINT. -It may exit, do something else or do nothing. Still, when the user hit -SIGINT, all the outer programs are awaken, get the signal and may -react on it. - -

What we try to achieve

- -The problem is with shell scripts (or similar programs that call -several subprograms one after another). - -

Let us consider the most basic script: -

-#! /bin/sh
-program1
-program2
-
-and the usual run looks like this: -
-$ sh myscript
-[output of program1]
-[output of program2]
-$
-
- -

Let us assume that both programs do nothing special on SIGINT, they -just exit. - -

Now imagine the user hits C-c while a shellscript is executing its -first program. The following programs receive SIGINT: program1 and -also the shell executing the script. program1 exits. - -

But what should the shell do? If we say that it is only the -innermost's programs business to react on SIGINT, the shell will do -nothing special (not exit) and it will continue the execution of the -script and run program2. But this is wrong: The user's intention in -hitting C-c is to abort the whole script, to get his prompt back. If -he hits C-c while the first program is running, he does not want -program2 to be even started. - -

here is what would happen if the shell doesn't do anything: -

-$ sh myscript
-[first half of program1's output]
-C-c   [users presses C-c]
-[second half of program1's output will not be displayed]
-[output of program2 will appear]
-
- - -

Consider a more annoying example: -

-#! /bin/sh
-# let's assume there are 300 *.dat files
-for file in *.dat ; do
-	dat2ascii $dat
-done
-
- -If your shell wouldn't end if the user hits C-c, -C-c would just end one dat2ascii run and -the script would continue. Thus, you had to hit C-c up to -300 times to end this script. - -

Alternatives to do so

- -

There are several ways to handle abortion of shell scripts when -SIGINT is received while a foreground child runs: - -

- -
  • As just outlined, the shellscript may just continue, ignoring the -fact that the user hit C-c. That way, your shellscript - -including any loops - would continue and you had no chance of aborting -it except using the kill command after finding out the outermost -shell's PID. This "solution" will not be discussed further, as it is -obviously not desirable. - -

  • The shell itself exits immediately when it receives SIGINT. Not -only the program called will exit, but the calling (the -script-executing) shell. The first variant is to exit the shell (and -therefore discontinuing execution of the script) immediately, while -the background program may still be executing (remember that although -the shell is just waiting for the called program to exit, it is woken -up and may act). I will call the way of doing things the "IUE" (for -"immediate unconditional exit") for the rest of this document. - -

  • As a variant of the former, when the shell receives SIGINT -while it is waiting for a child to exit, the shell does not exit -immediately. but it remembers the fact that a SIGINT happened. After -the called program exits and the shell's wait ends, the shell will -exit itself and hence discontinue the script. I will call the way of -doing things the "WUE" (for "wait and unconditional exit") for the -rest of this document. - -

  • There is also a way that the calling shell can tell whether the -called program exited on SIGINT and if it ignored SIGINT (or used it -for other purposes). As in the WUE way, the shell waits for -the child to complete. It figures whether the program was ended on -SIGINT and if so, it discontinue the script. If the program did any -other exit, the script will be continued. I will call the way of doing -things the "WCE" (for "wait and cooperative exit") for the rest of -this document. - -
    •  - -

    The problem

    - -On first sight, all three solutions (IUE, WUE and WCE) all seem to do -what we want: If C-c is hit while the first program of the shell -script runs, the script is discontinued. The user gets his prompt back -immediately. So what are the difference between these way of handling -SIGINT? - -

    There are programs that use the signal SIGINT for other purposes -than exiting. They use it as a normal keystroke. The user is expected -to use the key that sends SIGINT during a perfectly normal program -run. As a result, the user sends SIGINT in situations where he/she -does not want the program or the script to end. - -

    The primary example is the emacs editor: C-g does what ESC does in -other applications: It cancels a partially executed or prepared -operation. Technically, emacs remaps the key that sends SIGINT from -C-c to C-g and catches SIGINT. - -

    Remember that the SIGINT is sent to all programs running in the -foreground. If emacs is executing from a shell script, both emacs and -the shell get SIGINT. emacs is the program that decides what to do: -Exit on SIGINT or not. emacs decides not to exit. The problem arises -when the shell draws its own conclusions from receiving SIGINT without -consulting emacs for its opinion. - -

    Consider this script: -

    -#! /bin/sh
-emacs /tmp/foo
-cp /tmp/foo /home/user/mail/sent
-
    - -

    If C-g is used in emacs, both the shell and emacs will received -SIGINT. Emacs will not exit, the user used C-g as a normal editing -keystroke, he/she does not want the script to be aborted on C-g. - -

    The central problem is that the second command (cp) may -unintentionally be killed when the shell draws its own conclusion -about the user's intention. The innermost program is the only one to -judge. - -

    One more example

    - -

    Imagine a mail session using a curses mailer in a tty. You called -your mailer and started to compose a message. Your mailer calls emacs. -C-g is a normal editing key in emacs. Technically it -sends SIGINT (it was C-c, but emacs remapped the key) to -

    -
  • emacs -
  • the shell between your mailer and emacs, the one from your mailers - system("emacs /tmp/bla.44") command -
  • the mailer itself -
  • possibly another shell if your mailer was called by a shell script -or from another application using system(3) -
  • your interactive shell (which ignores it since it is interactive -and hence is not relevant to this discussion) -
    •  - -

    If everyone just exits on SIGINT, you will be left with nothing but -your login shell, without asking. - -

    But for sure you don't want to be dropped out of your editor and -out of your mailer back to the commandline, having your edited data -and mailer status deleted. - -

    Understand the difference: While C-g is used an a kind -of abort key in emacs, it isn't the major "abort everything" key. When -you use C-g in emacs, you want to end some internal emacs -command. You don't want your whole emacs and mailer session to end. - -

    So, if the shell exits immediately if the user sends SIGINT (the -second of the four ways shown above), the parent of emacs would die, -leaving emacs without the controlling tty. The user will lose it's -editing session immediately and unrecoverable. If the "main" shell of -the operating system defaults to this behavior, every editor session -that is spawned from a mailer or such will break (because it is -usually executed by system(3), which calls /bin/sh). This was the case -in FreeBSD before I and Bruce Evans changed it in 1998. - -

    If the shell recognized that SIGINT was sent and exits after the -current foreground process exited (the third way of the four), the -editor session will not be disturbed, but things will still not work -right. - -

    A further look at the alternatives

    - -

    Still considering this script to examine the shell's actions in the -IUE, WUE and ICE way of handling SIGINT: -

    -#! /bin/sh
-emacs /tmp/foo
-cp /tmp/foo /home/user/mail/sent
-
    - -

    The IUE ("immediate unconditional exit") way does not work at all: -emacs wants to survive the SIGINT (it's a normal editing key for -emacs), but its parent shell unconditionally thinks "We received -SIGINT. Abort everything. Now.". The shell will exit even before emacs -exits. But this will leave emacs in an unusable state, since the death -of its calling shell will leave it without required resources (file -descriptors). This way does not work at all for shellscripts that call -programs that use SIGINT for other purposes than immediate exit. Even -for programs that exit on SIGINT, but want to do some cleanup between -the signal and the exit, may fail before they complete their cleanup. - -

    It should be noted that this way has one advantage: If a child -blocks SIGINT and does not exit at all, this way will get control back -to the user's terminal. Since such programs should be banned from your -system anyway, I don't think that weighs against the disadvantages. - -

    WUE ("wait and unconditional exit") is a little more clever: If C-g -was used in emacs, the shell will get SIGINT. It will not immediately -exit, but remember the fact that a SIGINT happened. When emacs ends -(maybe a long time after the SIGINT), it will say "Ok, a SIGINT -happened sometime while the child was executing, the user wants the -script to be discontinued". It will then exit. The cp will not be -executed. But that's bad. The "cp" will be executed when the emacs -session ended without the C-g key ever used, but it will not be -executed when the user used C-g at least one time. That is clearly not -desired. Since C-g is a normal editing key in emacs, the user expects -the rest of the script to behave identically no matter what keys he -used. - -

    As a result, the "WUE" way is better than the "IUE" way in that it -does not break SIGINT-using programs completely. The emacs session -will end undisturbed. But it still does not support scripts where -other actions should be performed after a program that use SIGINT for -non-exit purposes. Since the behavior is basically undeterminable for -the user, this can lead to nasty surprises. - -

    The "WCE" way fixes this by "asking" the called program whether it -exited on SIGINT or not. While emacs receives SIGINT, it does not exit -on it and a calling shell waiting for its exit will not be told that -it exited on SIGINT. (Although it receives SIGINT at some point in -time, the system does not enforce that emacs will exit with -"I-exited-on-SIGINT" status. This is under emacs' control, see below). - -

    this still work for the normal script without SIGINT-using -programs:

    -
    -#! /bin/sh
-program1
-program2
-
    - -Unless program1 and program2 mess around with signal handling, the -system will tell the calling shell whether the programs exited -normally or as a result of SIGINT. - -

    The "WCE" way then has an easy way to things right: When one called -program exited with "I-exited-on-SIGINT" status, it will discontinue -the script after this program. If the program ends without this -status, the next command in the script is started. - -

    It is important to understand that a shell in "WCE" modus does not -need to listen to the SIGINT signal at all. Both in the -"emacs-then-cp" script and in the "several-normal-programs" script, it -will be woken up and receive SIGINT when the user hits the -corresponding key. But the shell does not need to react on this event -and it doesn't need to remember the event of any SIGINT, either. -Telling whether the user wants to end a script is done by asking that -program that has to decide, that program that interprets keystrokes -from the user, the innermost program. - -

    So everything is well with WCE?

    - -Well, almost. - -

    The problem with the "WCE" modus is that there are broken programs -that do not properly communicate the required information up to the -calling program. - -

    Unless a program messes with signal handling, the system does this -automatically. - -

    There are programs that want to exit on SIGINT, but they don't let -the system do the automatic exit, because they want to do some -cleanup. To do so, they catch SIGINT, do the cleanup and then exit by -themselves. - -

    And here is where the problem arises: Once they catch the signal, -the system will no longer communicate the "I-exited-on-SIGINT" status -to the calling program automatically. Even if the program exit -immediately in the signal handler of SIGINT. Once it catches the -signal, it has to take care of communicating the signal status -itself. - -

    Some programs don't do this. On SIGINT, they do cleanup and exit -immediatly, but the calling shell isn't told about the non-normal exit -and it will call the next program in the script. - -

    As a result, the user hits SIGINT and while one program exits, the -shellscript continues. To him/her it looks like the shell fails to -obey to his abortion command. - -

    Both IUE or WUE shell would not have this problem, since they -discontinue the script on their own. But as I said, they don't support -programs using SIGINT for non-exiting purposes, no matter whether -these programs properly communicate their signal status to the calling -shell or not. - -

    Since some shell in wide use implement the WUE way (and some even -IUE), there is a considerable number of broken programs out there that -break WCE shells. The programmers just don't recognize it if their -shell isn't WCE. - -

    How to be a proper program

    - -

    (Short note in advance: What you need to achieve is that -WIFSIGNALED(status) is true in the calling program and that -WTERMSIG(status) returns SIGINT.) - -

    If you don't catch SIGINT, the system automatically does the right -thing for you: Your program exits and the calling program gets the -right "I-exited-on-SIGINT" status after waiting for your exit. - -

    But once you catch SIGINT, you have to act. - -

    Decide whether the SIGINT is used for exit/abort purposes and hence -a shellscript calling this program should discontinue. This is -hopefully obvious. If you just need to do some cleanup on SIGINT, but -then exit immediately, the answer is "yes". - -

    If so, you have to tell the calling program about it by exiting -with the "I-exited-on-SIGINT" status. - -

    There is no other way of doing this than to kill yourself with a -SIGINT signal. Do it by resetting the SIGINT handler to SIG_DFL, then -send yourself the signal. - -

    -void sigint_handler(int sig)
-{
-	
-	signal(SIGINT, SIG_DFL);
-	kill(getpid(), SIGINT);
-}
-
    - -Notes: - - - -
  • You cannot "fake" the proper exit status by an exit(3) with a -special numeric value. People often assume this since the manuals for -shells often list some return value for exactly this. But this is just -a convention for your shell script. It does not work from one UNIX API -program to another. - -

    All that happens is that the shell sets the "$?" variable to a -special numeric value for the convenience of your script, because your -script does not have access to the lower-lever UNIX status evaluation -functions. This is just an agreement between your script and the -executing shell, it does not have any meaning in other contexts. - -

  • Do not use kill(0, SIGINT) without consulting the manul for -your OS implementation. I.e. on BSD, this would not send the signal to -the current process, but to all processes in the group. - -

  • POSIX 1003.1 allows all these calls to appear in signal -handlers, so it is portable. - -

    In a bourne shell script, you can catch signals using the -trap command. Here, the same as for C programs apply. If -the intention of SIGINT is to end your program, you have to exit in a -way that the calling programs "sees" that you have been killed. If -you don't catch SIGINT, this happend automatically, but of you catch -SIGINT, i.e. to do cleanup work, you have to end the program by -killing yourself, not by calling exit. - -

    Consider this example from FreeBSD's mkdep, which is a -bourne shell script. - -

    -TMP=_mkdep$$
-trap 'rm -f $TMP ; trap 2 ; kill -2 $$' 1 2 3 13 15
-
    - -Yes, you have to do it the hard way. It's even more annoying in shell -scripts than in C programs since you can't "pre-delete" temporary -files (which isn't really portable in C, though). - -

    All this applies to programs in all languages, not only C and -bourne shell. Every language implementation that lets you catch SIGINT -should also give you the option to reset the signal and kill yourself. - -

    It is always desireable to exit the right way, even if you don't -expect your usual callers to depend on it, some unusual one will come -along. This proper exit status will be needed for WCE and will not -hurt when the calling shell uses IUE or WUE. - -

    How to be a proper shell

    - -All this applies only for the script-executing case. Most shells will -also have interactive modes where things are different. - - - -
  • Do nothing special when SIGINT appears while you wait for a child. -You don't even have to remember that one happened. - -

  • Wait for child to exit, get the exit status. Do not truncate it -to type char. - -

  • Look at WIFSIGNALED(status) and WTERMSIG(status) to tell -whether the child says "I exited on SIGINT: in my opinion the user -wants the shellscript to be discontinued". - -

  • If the latter applies, discontinue the script. - -

  • Exit. But since a shellscript may in turn be called by a -shellscript, you need to make sure that you properly communicate the -discontinue intention to the calling program. As in any other program -(see above), do - -
    -	signal(SIGINT, SIG_DFL);
-	kill(getpid(), SIGINT);
-
    - -
    •  - -

    Other remarks

    - -Although this web page talks about SIGINT only, almost the same issues -apply to SIGQUIT, including proper exiting by killing yourself after -catching the signal and proper reaction on the WIFSIGNALED(status) -value. One notable difference for SIGQUIT is that you have to make -sure that not the whole call tree dumps core. - -

    What to fight

    - -Make sure all programs really kill themselves if they react -to SIGINT or SIGQUIT and intend to abort their operation as a result -of this signal. Programs that don't use SIGINT/SIGQUIT as a -termination trigger - but as part of normal operation - don't kill -themselves, but do a normal exit instead. - -

    Make sure people understand why you can't fake an exit-on-signal by -doing exit(...) using any numerical status. - -

    Make sure you use a shell that behaves right. Especially if you -develop programs, since it will help seeing problems. - -

    Concrete examples how to fix programs:

    -
      - -
    • The fix for FreeBSD's -time(1). This fix is the best example, it's quite short and clear and -it fixes a case where someone tried to fake signal exit status by a -numerical value. And the complete program is small. - -

    • Fix for FreeBSD's -truss(1). - -

    • The fix for FreeBSD's -mkdep(1), a shell script. - - -

    • Fix for FreeBSD's make(1), part 1, -part 2. - -
    - -

    Testsuite for shells

    - -I have a collection of shellscripts that test shells for the -behavior. See my download dir to get the newest -"sh-interrupt" files, either as a tarfile or as individual file for -online browsing. This isn't really documented, besides from the -comments the scripts echo. - -

This way you can run GNU indent on your -files by typing 'indent myfile.c myfile.h' and it will magically apply all the -right formatting rules to your file. Please _do_not_ run this on all the files -in the directory, just your own. - - - -Declaration Order ------------------ - -Here is the preferred order in which code should be laid out in a file: - - - commented program name and one-line description - - commented author name and email address(es) - - commented GPL boilerplate - - commented longer description / notes for the program (if needed) - - #includes of .h files with angle brackets (<>) around them - - #includes of .h files with quotes ("") around them - - #defines (if any, note the section below titled "Avoid the Preprocessor") - - const and global variables - - function declarations (if necessary) - - function implementations - - - -Whitespace and Formatting -------------------------- - -This is everybody's favorite flame topic so let's get it out of the way right -up front. - - -Tabs vs. Spaces in Line Indentation -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The preference in Busybox is to indent lines with tabs. Do not indent lines -with spaces and do not indents lines using a mixture of tabs and spaces. (The -indentation style in the Apache and Postfix source does this sort of thing: -\s\s\s\sif (expr) {\n\tstmt; --ick.) The only exception to this rule is -multi-line comments that use an asterisk at the beginning of each line, i.e.: - - \t/* - \t * This is a block comment. - \t * Note that it has multiple lines - \t * and that the beginning of each line has a tab plus a space - \t * except for the opening '/*' line where the slash - \t * is used instead of a space. - \t */ - -Furthermore, The preference is that tabs be set to display at four spaces -wide, but the beauty of using only tabs (and not spaces) at the beginning of -lines is that you can set your editor to display tabs at *whatever* number of -spaces is desired and the code will still look fine. - - -Operator Spacing -~~~~~~~~~~~~~~~~ - -Put spaces between terms and operators. Example: - - Don't do this: - - for(i=0;i 0) - - -Bracket Spacing -~~~~~~~~~~~~~~~ - -If an opening bracket starts a function, it should be on the -next line with no spacing before it. However, if a bracket follows an opening -control block, it should be on the same line with a single space (not a tab) -between it and the opening control block statement. Examples: - - Don't do this: - - while (!done) - { - - do - { - - Don't do this either: - - while (!done){ - - do{ - - And for heaven's sake, don't do this: - - while (!done) - { - - do - { - - Do this instead: - - while (!done) { - - do { - -If you have long logic statements that need to be wrapped, then uncuddling -the bracket to improve readability is allowed. Generally, this style makes -it easier for reader to notice that 2nd and following lines are still -inside 'if': - - if (some_really_long_checks && some_other_really_long_checks - && some_more_really_long_checks - && even_more_of_long_checks - ) { - do_foo_now; - -Spacing around Parentheses -~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Put a space between C keywords and left parens, but not between function names -and the left paren that starts it's parameter list (whether it is being -declared or called). Examples: - - Don't do this: - - while(foo) { - for(i = 0; i < n; i++) { - - Do this instead: - - while (foo) { - for (i = 0; i < n; i++) { - - But do functions like this: - - static int my_func(int foo, char bar) - ... - baz = my_func(1, 2); - -Also, don't put a space between the left paren and the first term, nor between -the last arg and the right paren. - - Don't do this: - - if ( x < 1 ) - strcmp( thisstr, thatstr ) - - Do this instead: - - if (x < 1) - strcmp(thisstr, thatstr) - - -Cuddled Elses -~~~~~~~~~~~~~ - -Also, please "cuddle" your else statements by putting the else keyword on the -same line after the right bracket that closes an 'if' statement. - - Don't do this: - - if (foo) { - stmt; - } - else { - stmt; - } - - Do this instead: - - if (foo) { - stmt; - } else { - stmt; - } - -The exception to this rule is if you want to include a comment before the else -block. Example: - - if (foo) { - stmts... - } - /* otherwise, we're just kidding ourselves, so re-frob the input */ - else { - other_stmts... - } - - -Labels -~~~~~~ - -Labels should start at the beginning of the line, not indented to the block -level (because they do not "belong" to block scope, only to whole function). - - if (foo) { - stmt; - label: - stmt2; - stmt; - } - -(Putting label at position 1 prevents diff -p from confusing label for function -name, but it's not a policy of busybox project to enforce such a minor detail). - - - -Variable and Function Names ---------------------------- - -Use the K&R style with names in all lower-case and underscores occasionally -used to separate words (e.g., "variable_name" and "numchars" are both -acceptable). Using underscores makes variable and function names more readable -because it looks like whitespace; using lower-case is easy on the eyes. - - Frowned upon: - - hitList - TotalChars - szFileName - pf_Nfol_TriState - - Preferred: - - hit_list - total_chars - file_name - sensible_name - -Exceptions: - - - Enums, macros, and constant variables are occasionally written in all - upper-case with words optionally separated by underscores (i.e. FIFO_TYPE, - ISBLKDEV()). - - - Nobody is going to get mad at you for using 'pvar' as the name of a - variable that is a pointer to 'var'. - - -Converting to K&R -~~~~~~~~~~~~~~~~~ - -The Busybox codebase is very much a mixture of code gathered from a variety of -sources. This explains why the current codebase contains such a hodge-podge of -different naming styles (Java, Pascal, K&R, just-plain-weird, etc.). The K&R -guideline explained above should therefore be used on new files that are added -to the repository. Furthermore, the maintainer of an existing file that uses -alternate naming conventions should, at his own convenience, convert those -names over to K&R style. Converting variable names is a very low priority -task. - -If you want to do a search-and-replace of a single variable name in different -files, you can do the following in the busybox directory: - - $ perl -pi -e 's/\bOldVar\b/new_var/g' *.[ch] - -If you want to convert all the non-K&R vars in your file all at once, follow -these steps: - - - In the busybox directory type 'examples/mk2knr.pl files-to-convert'. This - does not do the actual conversion, rather, it generates a script called - 'convertme.pl' that shows what will be converted, giving you a chance to - review the changes beforehand. - - - Review the 'convertme.pl' script that gets generated in the busybox - directory and remove / edit any of the substitutions in there. Please - especially check for false positives (strings that should not be - converted). - - - Type './convertme.pl same-files-as-before' to perform the actual - conversion. - - - Compile and see if everything still works. - -Please be aware of changes that have cascading effects into other files. For -example, if you're changing the name of something in, say utility.c, you -should probably run 'examples/mk2knr.pl utility.c' at first, but when you run -the 'convertme.pl' script you should run it on _all_ files like so: -'./convertme.pl *.[ch]'. - - - -Avoid The Preprocessor ----------------------- - -At best, the preprocessor is a necessary evil, helping us account for platform -and architecture differences. Using the preprocessor unnecessarily is just -plain evil. - - -The Folly of #define -~~~~~~~~~~~~~~~~~~~~ - -Use 'const var' for declaring constants. - - Don't do this: - - #define CONST 80 - - Do this instead, when the variable is in a header file and will be used in - several source files: - - enum { CONST = 80 }; - -Although enum may look ugly to some people, it is better for code size. -With "const int" compiler may fail to optimize it out and will reserve -a real storage in rodata for it! (Hopefully, newer gcc will get better -at it...). With "define", you have slight risk of polluting namespace -(#define doesn't allow you to redefine the name in the inner scopes), -and complex "define" are evaluated each time they uesd, not once -at declarations like enums. Also, the preprocessor does _no_ type checking -whatsoever, making it much more error prone. - - -The Folly of Macros -~~~~~~~~~~~~~~~~~~~ - -Use 'static inline' instead of a macro. - - Don't do this: - - #define mini_func(param1, param2) (param1 << param2) - - Do this instead: - - static inline int mini_func(int param1, param2) - { - return (param1 << param2); - } - -Static inline functions are greatly preferred over macros. They provide type -safety, have no length limitations, no formatting limitations, have an actual -return value, and under gcc they are as cheap as macros. Besides, really long -macros with backslashes at the end of each line are ugly as sin. - - -The Folly of #ifdef -~~~~~~~~~~~~~~~~~~~ - -Code cluttered with ifdefs is difficult to read and maintain. Don't do it. -Instead, put your ifdefs at the top of your .c file (or in a header), and -conditionally define 'static inline' functions, (or *maybe* macros), which are -used in the code. - - Don't do this: - - ret = my_func(bar, baz); - if (!ret) - return -1; - #ifdef CONFIG_FEATURE_FUNKY - maybe_do_funky_stuff(bar, baz); - #endif - - Do this instead: - - (in .h header file) - - #if ENABLE_FEATURE_FUNKY - static inline void maybe_do_funky_stuff(int bar, int baz) - { - /* lotsa code in here */ - } - #else - static inline void maybe_do_funky_stuff(int bar, int baz) {} - #endif - - (in the .c source file) - - ret = my_func(bar, baz); - if (!ret) - return -1; - maybe_do_funky_stuff(bar, baz); - -The great thing about this approach is that the compiler will optimize away -the "no-op" case (the empty function) when the feature is turned off. - -Note also the use of the word 'maybe' in the function name to indicate -conditional execution. - - - -Notes on Strings ----------------- - -Strings in C can get a little thorny. Here's some guidelines for dealing with -strings in Busybox. (There is surely more that could be added to this -section.) - - -String Files -~~~~~~~~~~~~ - -Put all help/usage messages in usage.c. Put other strings in messages.c. -Putting these strings into their own file is a calculated decision designed to -confine spelling errors to a single place and aid internationalization -efforts, if needed. (Side Note: we might want to use a single file - maybe -called 'strings.c' - instead of two, food for thought). - - -Testing String Equivalence -~~~~~~~~~~~~~~~~~~~~~~~~~~ - -There's a right way and a wrong way to test for string equivalence with -strcmp(): - - The wrong way: - - if (!strcmp(string, "foo")) { - ... - - The right way: - - if (strcmp(string, "foo") == 0){ - ... - -The use of the "equals" (==) operator in the latter example makes it much more -obvious that you are testing for equivalence. The former example with the -"not" (!) operator makes it look like you are testing for an error. In a more -perfect world, we would have a streq() function in the string library, but -that ain't the world we're living in. - - -Avoid Dangerous String Functions -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Unfortunately, the way C handles strings makes them prone to overruns when -certain library functions are (mis)used. The following table offers a summary -of some of the more notorious troublemakers: - -function overflows preferred -------------------------------------------------- -strcpy dest string safe_strncpy -strncpy may fail to 0-terminate dst safe_strncpy -strcat dest string strncat -gets string it gets fgets -getwd buf string getcwd -[v]sprintf str buffer [v]snprintf -realpath path buffer use with pathconf -[vf]scanf its arguments just avoid it - - -The above is by no means a complete list. Be careful out there. - - - -Avoid Big Static Buffers ------------------------- - -First, some background to put this discussion in context: static buffers look -like this in code: - - /* in a .c file outside any functions */ - static char buffer[BUFSIZ]; /* happily used by any function in this file, - but ick! big! */ - -The problem with these is that any time any busybox app is run, you pay a -memory penalty for this buffer, even if the applet that uses said buffer is -not run. This can be fixed, thusly: - - static char *buffer; - ... - other_func() - { - strcpy(buffer, lotsa_chars); /* happily uses global *buffer */ - ... - foo_main() - { - buffer = xmalloc(sizeof(char)*BUFSIZ); - ... - -However, this approach trades bss segment for text segment. Rather than -mallocing the buffers (and thus growing the text size), buffers can be -declared on the stack in the *_main() function and made available globally by -assigning them to a global pointer thusly: - - static char *pbuffer; - ... - other_func() - { - strcpy(pbuffer, lotsa_chars); /* happily uses global *pbuffer */ - ... - foo_main() - { - char *buffer[BUFSIZ]; /* declared locally, on stack */ - pbuffer = buffer; /* but available globally */ - ... - -This last approach has some advantages (low code size, space not used until -it's needed), but can be a problem in some low resource machines that have -very limited stack space (e.g., uCLinux). - -A macro is declared in busybox.h that implements compile-time selection -between xmalloc() and stack creation, so you can code the line in question as - - RESERVE_CONFIG_BUFFER(buffer, BUFSIZ); - -and the right thing will happen, based on your configuration. - -Another relatively new trick of similar nature is explained -in keep_data_small.txt. - - - -Miscellaneous Coding Guidelines -------------------------------- - -The following are important items that don't fit into any of the above -sections. - - -Model Busybox Applets After GNU Counterparts -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -When in doubt about the proper behavior of a Busybox program (output, -formatting, options, etc.), model it after the equivalent GNU program. -Doesn't matter how that program behaves on some other flavor of *NIX; doesn't -matter what the POSIX standard says or doesn't say, just model Busybox -programs after their GNU counterparts and it will make life easier on (nearly) -everyone. - -The only time we deviate from emulating the GNU behavior is when: - - - We are deliberately not supporting a feature (such as a command line - switch) - - Emulating the GNU behavior is prohibitively expensive (lots more code - would be required, lots more memory would be used, etc.) - - The difference is minor or cosmetic - -A note on the 'cosmetic' case: output differences might be considered -cosmetic, but if the output is significant enough to break other scripts that -use the output, it should really be fixed. - - -Scope -~~~~~ - -If a const variable is used only in a single source file, put it in the source -file and not in a header file. Likewise, if a const variable is used in only -one function, do not make it global to the file. Instead, declare it inside -the function body. Bottom line: Make a conscious effort to limit declarations -to the smallest scope possible. - -Inside applet files, all functions should be declared static so as to keep the -global name space clean. The only exception to this rule is the "applet_main" -function which must be declared extern. - -If you write a function that performs a task that could be useful outside the -immediate file, turn it into a general-purpose function with no ties to any -applet and put it in the utility.c file instead. - - -Brackets Are Your Friends -~~~~~~~~~~~~~~~~~~~~~~~~~ - -Please use brackets on all if and else statements, even if it is only one -line. Example: - - Don't do this: - - if (foo) - stmt1; - stmt2 - stmt3; - - Do this instead: - - if (foo) { - stmt1; - } - stmt2 - stmt3; - -The "bracketless" approach is error prone because someday you might add a line -like this: - - if (foo) - stmt1; - new_line(); - stmt2; - stmt3; - -And the resulting behavior of your program would totally bewilder you. (Don't -laugh, it happens to us all.) Remember folks, this is C, not Python. - - -Function Declarations -~~~~~~~~~~~~~~~~~~~~~ - -Do not use old-style function declarations that declare variable types between -the parameter list and opening bracket. Example: - - Don't do this: - - int foo(parm1, parm2) - char parm1; - float parm2; - { - .... - - Do this instead: - - int foo(char parm1, float parm2) - { - .... - -The only time you would ever need to use the old declaration syntax is to -support ancient, antediluvian compilers. To our good fortune, we have access -to more modern compilers and the old declaration syntax is neither necessary -nor desired. - - -Emphasizing Logical Blocks -~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Organization and readability are improved by putting extra newlines around -blocks of code that perform a single task. These are typically blocks that -begin with a C keyword, but not always. - -Furthermore, you should put a single comment (not necessarily one line, just -one comment) before the block, rather than commenting each and every line. -There is an optimal amount of commenting that a program can have; you can -comment too much as well as too little. - -A picture is really worth a thousand words here, the following example -illustrates how to emphasize logical blocks: - - while (line = xmalloc_fgets(fp)) { - - /* eat the newline, if any */ - chomp(line); - - /* ignore blank lines */ - if (strlen(file_to_act_on) == 0) { - continue; - } - - /* if the search string is in this line, print it, - * unless we were told to be quiet */ - if (strstr(line, search) && !be_quiet) { - puts(line); - } - - /* clean up */ - free(line); - } - - -Processing Options with getopt -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -If your applet needs to process command-line switches, please use getopt32() to -do so.

J[i] = 0 if there is no - * such line in file1. - * - * Lines are hashed so as to work in core. All potential - * matches are located by sorting the lines of each file - * on the hash (called "value"). In particular, this - * collects the equivalence classes in file1 together. - * Subroutine equiv replaces the value of each line in - * file0 by the index of the first element of its - * matching equivalence in (the reordered) file1. - * To save space equiv squeezes file1 into a single - * array member in which the equivalence classes - * are simply concatenated, except that their first - * members are flagged by changing sign. - * - * Next the indices that point into member are unsorted into - * array class according to the original order of file0. - * - * The cleverness lies in routine stone. This marches - * through the lines of file0, developing a vector klist - * of "k-candidates". At step i a k-candidate is a matched - * pair of lines x,y (x in file0, y in file1) such that - * there is a common subsequence of length k - * between the first i lines of file0 and the first y - * lines of file1, but there is no such subsequence for - * any smaller y. x is the earliest possible mate to y - * that occurs in such a subsequence. - * - * Whenever any of the members of the equivalence class of - * lines in file1 matable to a line in file0 has serial number - * less than the y of some k-candidate, that k-candidate - * with the smallest such y is replaced. The new - * k-candidate is chained (via pred) to the current - * k-1 candidate so that the actual subsequence can - * be recovered. When a member has serial number greater - * that the y of all k-candidates, the klist is extended. - * At the end, the longest subsequence is pulled out - * and placed in the array J by unravel - * - * With J in hand, the matches there recorded are - * checked against reality to assure that no spurious - * matches have crept in due to hashing. If they have, - * they are broken, and "jackpot" is recorded--a harmless - * matter except that a true match for a spuriously - * mated line may now be unnecessarily reported as a change. - * - * Much of the complexity of the program comes simply - * from trying to minimize core utilization and - * maximize the range of doable problems by dynamically - * allocating what is needed and reusing what is not. - * The core requirements for problems larger than somewhat - * are (in words) 2*length(file0) + length(file1) + - * 3*(number of k-candidates installed), typically about - * 6n words for files of length n. - */ - -//usage:#define diff_trivial_usage -//usage: "[-abBdiNqrTstw] [-L LABEL] [-S FILE] [-U LINES] FILE1 FILE2" -//usage:#define diff_full_usage "\n\n" -//usage: "Compare files line by line and output the differences between them.\n" -//usage: "This implementation supports unified diffs only.\n" -//usage: "\n -a Treat all files as text" -//usage: "\n -b Ignore changes in the amount of whitespace" -//usage: "\n -B Ignore changes whose lines are all blank" -//usage: "\n -d Try hard to find a smaller set of changes" -//usage: "\n -i Ignore case differences" -//usage: "\n -L Use LABEL instead of the filename in the unified header" -//usage: "\n -N Treat absent files as empty" -//usage: "\n -q Output only whether files differ" -//usage: "\n -r Recurse" -//usage: "\n -S Start with FILE when comparing directories" -//usage: "\n -T Make tabs line up by prefixing a tab when necessary" -//usage: "\n -s Report when two files are the same" -//usage: "\n -t Expand tabs to spaces in output" -//usage: "\n -U Output LINES lines of context" -//usage: "\n -w Ignore all whitespace" - -#include "libbb.h" - -#if 0 -# define dbg_error_msg(...) bb_error_msg(__VA_ARGS__) -#else -# define dbg_error_msg(...)
