103 * Larry Doolittle -- shell data structure cleanup, fixed buglets
104 in read, exec, and piped builtins
105 * Erik Andersen -- md5sum was broken in 0.48. Now fixed (and doesn't
106 use getline, shrinking static compiles (since nothing else used it).
107 * ?? -- squashed memory leak in shell prompt handling
108 * Mark Whitley -- Updates to style guide
109 * Mark Whitley -- Big cleanup in utility.c: style guide compliance,
110 de-macro-ifying some variables and functions
111 * Erik Andersen -- ls now honors BB_FEATURE_AUTOWIDTH so it can find
112 the width and height of the console.
113 * Erik Andersen -- insmod now ignores -L and accepts the -o option.
114 * Erik Andersen -- updates so you can now select from the Makefile
115 whether or not to use the system's passwd and group functions.
116 Since most systems use GNU libc, this can save you from having to
117 install the /etc/nsswitch.conf configuration file and the required
118 libnss_* libraries. Adds 1.5k. You can now, also, disable this,
119 causing busybox to use the system's pwd.h and grp.h functions.
122 -Erik Andersen, 27 January 2001
126 * Glenn McGrath -- tar now supports uncompressing tar files,
127 define BB_FEATURE_TAR_GZIP to use the -z option.
128 * Matt Kraai -- fix all usage of TRUE and FALSE so all apps now
129 return EXIT_SUCCESS or EXIT_FAILURE to the system.
130 Now TRUE and FALSE are set to the C standard where TRUE=1.
131 * me -- Fixed uname problem causing the kernel version to be
132 mis-detected (causing problems with poweroff, init,
134 * Alcove, Julien Gaulmin <julien.gaulmin@alcove.fr> and
135 Nicolas Ferre <nicolas.ferre@alcove.fr> -- insmod support on ARM
136 and StrongArm, and suport for lsmod on older 2.0.x kernels.
137 * Kent Robotti -- Renamed unrpm to original rpmunpack, so you can use
138 an included shell script called unrpm as a front end to it. There's
139 also a shell script called undeb included for debian packages.
140 * Matt Kraai -- fix an infinite loop with ls -aR
141 * Larry Doolittle -- Shaved off about 100 bytes and 200 bytes heap
142 from date.c. Also document the "-d" option in the usage message.
143 * Gennady Feldman -- fixed dd to use blocksize when reading/writing,
144 (it was reading the whole thing and then writing it out). Also
145 updated usage information (was missing conv=notrunc) and added
147 * Larry Doolittle (in collaboration with Matt Kraai) -- allow for a
148 pristine source directory -- where all the .o files and such are
149 not placed into the source tree. Thanks Larry!
150 * Larry Doolittle -- use the applet definitions in applets.h
151 to autogenerate the applet function and usage prototypes.
152 * Sebastien Huet, Arne Bernin, and Kent Robotti -- Add in tar -X and
153 fixed a bug breaking tar --exclude.
154 * Jonas Holmberg -- echo option handling made GNU-echo compatible
155 * Aleksey Demidov <asd@ixcelerator.com> -- date option handling made
157 * me -- Progress meter (optional) in wget
158 * Doolittle/me -- programs invoked by full path name take
159 precedence over applets unless BB_FEATURE_SH_BUILTINS_ALWAYS_WIN
160 * Gaute B Strokkenes <gs234@cam.ac.uk> -- applets found using a
161 binary search instead of linear search. Much faster!
162 * new applets: cmp readlink
163 * Mark Whitley -- Removed advertising clause of Berkeley license
164 according to decision by the Regents of the University of
165 California; included reference
166 * tail's confusing special treatment of single digit options removed;
167 people should use -n instead
168 * Larry Doolittle -- \r handled now in echo and tr
169 * Matt Kraai -- rewrite of uniq
170 * Mark Whitley -- remix of xargs
171 * Jim Gleason <jimg@lineo.com> -- fixed tar so it no longer breaks
173 * Matt Kraai -- logger now logs all arguments, not just the first
174 * Gennady Feldman -- syslogd no longer logs to localhost if compiled
175 for remote logging...
176 * Richard June <rjune@ims1.imagestream-is.com> -- support for 'gzip -d'
177 * various artists -- Other good stuff that I forgot to document.
180 -Erik Andersen, 13 December 2000
184 * A bug in syslogd was fixed that allowed it to potentially fork-bomb
185 your system. Anyone using 0.46 syslogd should upgrade.
186 * Renamed busybox.defs.h to the more sensible "Config.h"
187 * Improved portability between different libcs.
188 * Many apps ported to use getopt()
189 * Common handling of '--help'
190 * All usage messages centralized.
191 * Added a bunch of new commands:
192 * 'rdate' contributed by Sterling Huxley <sterling@europa.com>
193 * 'wget' contributed by Chip Rosenthal <chip@unicom.com>,
194 <crosenth@covad.com> and Covad Communications
195 * 'getopt' from "Alfred M. Szmidt" <ams@trillian.itslinux.org>
196 * dos2unix, unix2dos, reset, and unrpm.c (and lots of help
197 debugging) thanks to Kent Robotti <robotti@metconnect.com>.
198 * 'renice' command, thanks to Dave Cinege <dcinege@psychosis.com>
199 * 'xargs' (written by me)
200 * 'expr' contributed by Edward Betts <edward@debian.org>, based
202 * lsmod now uses the query_module syscall, rather then /proc (me)
203 * syslogd can now log messages to remote hosts -- patch thanks
204 to Gyepi Sam <gyepi@praxis-sw.com>
205 * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>
206 * 'make install' now creates relative symlinks, and added a new
207 'make install-hardlinks' target to (tada) install hardlinks.
208 * Rewrite of 'tail' to make it simpler, smaller, and more robust.
209 It now weighs only 2.25k (3k when full featured). The code is
210 cleaner too, thanks to Allen Soard <esp-software@mail.hypermart.net>
211 * Add optional ls file sorting, thanks to a patch from
212 Sterling Huxley <sterling@europa.com>
213 * Fixed chmod option parsing so things like 'chmod -r /tmp/file'
214 now work (previously it thought -r was an option). Doh!
215 * Fixed tar handling of stdin and stdout
216 * Renamed "internal.h" to the more sensible "busybox.h"
217 * Preliminary support for GNU HURD.
218 * Updated my devps and devmtab kernel patches for the latest 2.2.x
219 kernel, for those wanting to go proc-less.
220 * Tons of other bugfixes.
223 -Erik Andersen, 25 September 2000
228 * Better portability. Now should compile cleanly with libc5,
229 GNU libc 2.0 and 2.1, and various Linux kernels including
230 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
231 to make /proc/mounts behave included in the kernel-patches dir).
232 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
233 local files that matched tarball contents!!! Fix thanks
234 to Marius Groeger <mgroeger@sysgo.de>
235 * Fixed a nasty bug in tar when could mess up saved symlinks.
236 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
237 thanks to Daniel Quinlan <quinlan@transmeta.com>
238 * Updates to handle Linux 2.4.0 kernels (kludged around the
239 "none" entries in /proc/mounts, added a hack to make sysinfo
240 work with both old and new kernels).
241 * Fixed insmod module option parsing for options lacking an '='.
242 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
243 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
244 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
245 * Several fixes from Marius Groeger <mag@sysgo.de>
246 - Added support for "sh -c command args..."
247 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
248 - Added shell environment variable substitution
249 - Added the "read" shell builtin.
250 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
251 used to create an infinite loop: ls, cursor up, left, down.
252 * Added support for being a login shell, so things like
253 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
254 invoke the shell. Now you can use BusyBox as a login shell.
255 * ls.c now ignores '-g', since some ftp clients like that sort
256 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
257 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
258 it always sets the controlling terminal before running any programs
259 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
260 - Fixed tr so it recognizes standard escape sequences.
261 Merged common escape seq. code from tr and echo into utility.c.
262 - Major work in updating/cleaning up the docs, and getting the
263 new SGML based docs into shape.
265 - BusyBox should now poweroff when asked to do so.
266 - Fixed 'ln -n' and 'ln -s' so they both work properly.
267 * Reorganized signal names in kill.c for better architecture support
268 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
269 * In 0.43, backspace and delete worked properly, but with 0.45,
270 it just echoed a ^? for backspace, and ^H for control-h. This
271 was due to a broken macro in init.c, that is now fixed.
272 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
273 couldn't maintain it very well, so including it was not really
274 very appropriate. Those wanting an fdisk are invited to
275 grab a copy from util-linux.
276 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
277 then be loaded in by 'loadkmap' -- submitted by
278 Arne Bernin <arne@matrix.loopback.org>
279 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
280 * Brand, new versions of grep and sed which use libc regex routines,
281 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
282 "regexp.[ch]" files have been removed. Much help on these from
286 -Erik Andersen, 11 July 2000
290 * Now compiles vs libc5 (which can save lots of space for
292 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
293 help messages (i.e --help). Saves 17k over a full compile.
294 * Added cut and tr from minix, since due to the license change,
295 we can now use minix code. Minix tr saves 4k.
296 * insmod now works. It costs 29k, but imagine an initrd with a
297 staticly linked busybox containing only insmod and sh, a few /dev
298 entries, and a kernel module or two... It doesn't get smaller
299 then this folks (I pity the fool that writes insmod in asm ;-).
300 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
301 * Added a mini ar archive utility, especially written for BusyBox by
302 Glenn McGrath <bug1@netconnect.com.au>
303 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
304 * Added setkeycodes, for those that have wierd keyboard buttons.
305 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
306 <ams@trillian.itslinux.org> for contributing these.
307 * Added 'grep -v' option (inverted search) and updated
308 docs accordingly. -beppu
310 * Replaced the telnet implementation with one written by
311 Tomi Ollila <too@iki.fi> It works great and costs 3k.
312 * BusyBox sh (lash) now supports being used as a standalone shell. When
313 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
314 be invoked as shell internals. Best used when compiling staticly
316 * BusyBox sh (lash) internals now behave as expected wrt pipes
318 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
319 * Fixed update segfault
320 * Fixed mknod -- minor number was always 0
321 * Fixed tar option parsing, so both "tar xvf foo.tar" and
322 "tar -xvf foo.tar" now work (i.e. no "-" before options)
323 (this was very broken in 0.43).
324 * Several contributions from Randolph Chung <tausq@debian.org>.
325 * cp/mv now accepts the -f flag
326 * tail can now accept -<num> commands (e.g. -10) for better
327 compatibility with the standard tail command
328 * added a simple id implementation; doesn't support sup. groups yet
329 * logname used getlogin(3) which uses utmp. Now it doesn't.
330 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
331 * Add support for "noatime" and "nodiratime" mount flags to mount.
332 * Changed 'umount -f' to mean force, and actually use umount2.
333 * Changed 'umount -l' to mean "Do not free loop device".
334 * Fixed basename to support stripping of suffixes. Patch thanks
335 to xiong jianxin <jxiong@uiuc.edu>
336 * cp -fa now works as expected for symlinks (it didn't before)
337 * zcat now works (wasn't working since option parsing was broken)
338 * Renamed "mnc" to the more correct "nc" (for netcat).
339 * Makefile intelligence updates
340 * Changed the way init parses /etc/inittab entries to avoid problems
341 with commands that contain colons in them. Fix thanks to
342 Pavel Roskin <proski@gnu.org>
343 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
344 Fix thanks to Pavel Roskin <proski@gnu.org>
345 * Made "killall" complain (not error and exit) about processes that it
346 cannot find by name -- Pavel Roskin <proski@gnu.org>
347 * Fixed more and ps to have sensible terminal width defaults, thanks
349 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
350 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
351 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
352 * Fixed segfault caused by "touch -c"
353 * Fixed segfault caused by "rm -f"
354 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
355 and "--" support from Pavel Roskin.
356 * Fixed segfault caused by "cp -a -a" and similar abuses.
357 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
358 * "which" rewritten to use stat(). Fixes to improve its compatability
359 with traditional implementations -- Pavel Roskin.
360 * "mount" now reports errors from nfsmount() and assumes NFS mount
361 if ':' is present in the device name - Pavel Roskin
362 * Fixed exit status for killall - Pavel Roskin
363 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
364 * Fixed 'mount -a' so it works as expected.
365 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
366 * Implemented "ping -s", fixed error messages and argument parsing -
368 * Syslogd will not go to background if "-n" is given. Better help
369 and argument checking -- Pavel Roskin
370 * Fixed a small bug that could cause tar to emit warning messages
371 and not extract the first file in a directory in some cases
372 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
373 for helping track this one down.
375 * Fixed grep "Line too long" problem -- John Beppu
376 * Fixed 'grep -q -i B some_file' so it works
377 * math takes input from stdin if no args are given. -- John Beppu
378 * math was renamed to dc. Although it deviates from dc's behaviour,
379 this will probably be remedied in the future. -- John Beppu
382 -Erik Andersen, June 21, 2000
386 Previously, an erronous announcement of BusyBox 0.44 was made, so to
387 avoid possible confusion, we are skipping straight to 0.45, and calling
394 * Major update to the provided documentation.
395 * Busybox now includes a shell! It currently costs 7.5 k (plus an
396 additional 2.5 k if you compile in command line editing). Handles
397 job control, has the usual set of builtins, and does everything
398 except for handling programming statements (if, while, etc...)
399 * Busybox can now work perfectly when /proc is disabled, thereby
400 saving a bunch of memory (kernel /proc support is not thin). This
401 is done by making use of some nice kernel patches I wrote up to
402 support the features that busybox requires and that /proc usually
403 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
404 patch your kernel with the devps patch in the kernel-patches/
406 * Wrote basename, dirname, killall, and uptime.
407 * tar has been completely rewritten by me. Both tar creation and
408 extraction are now well behaved. Costs 7.6k with all optional
409 tar features enabled, and 5k for just tar extraction support.
410 * Added freeramdisk, which will free up all memory associated
411 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
412 and then adjusted a bit by me.
413 * Added tr from John Lombardo <john@deltanet.com>
414 * Added echo and test (from me).
415 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
416 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
417 * Several fixes from Pavel Roskin <proski@gnu.org>:
418 - When `tail' fails to open a file it now exits.
419 - When `syslogd' is given the `-n' option it should still use
420 fork() for running klogd.
421 * nslookup types are now changed to u_int32_t (instead of uint32_t)
422 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
423 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
424 to count hard-linked files more then once). Many thanks to
425 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
426 * Removed /proc dependancies for init and free (while maintaining
427 exactly the same functionality). /proc takes up 90k of kernel
428 space, so it is nice to avoid using it at all costs.
429 * init no longer tries to mount /proc (unless there is less the 1 meg
430 free). Use of /proc (or not) is policy that should be set up in
431 /etc/fstab (or in hardcoded scripts), not in init.
432 * Fixed rebooting when init runs as an initrd.
433 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
434 - update.c rewritten to look more like update-2.11
435 - moveed the inode hash out of du.c and into utility.c to make
436 it a common resource that can be used by other apps.
437 - cp_mv.c now checks inodes to see if a source and dest are
438 the same, and prints an error (instead of endlessly looping).
439 - mv now attempts to do a rename, and will fall back to doing
440 a copy only if the rename fails.
441 - Syslogd now supports multiple concurrent connections
442 * Several fixes from Pavel Roskin <proski@gnu.org>:
443 - Fixes to sort. Removed "-g", fixed and added "-r"
444 - Fixes to the makefile for handling "strip"
445 * An initial telnet implementation was added by
446 Randolph Chung <tausq@debian.org>.
447 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
448 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
449 to match the terminal (defaults to width=79 when this is off).
450 * ps now accepts (and ignores) all options except for "--help" (which
451 as would be expected displays help).
452 * Fixed mount'ing loop devices when the filesystem type was not
453 specified. It used to revert to non-loop after the first try.
454 * all mallocs now use xmalloc (and so are OOM error safe), and
455 the common error handling saves a few bytes. Thanks to
456 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
457 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
458 * Fix symlink following bug in chmod -R and friends.
459 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
460 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
469 * Fairly massive restructuring of umount.c to deal with remounting
470 busy devices read-only. Adds a -r option to control that; it is
471 optionally compiled in with BB_FEATURE_REMOUNT
472 * Added a bunch of functions to mtab.c to interact with the
473 {get,set,end}mntent interface; as it turns out, those functions do
474 not appear to be re-entrant, and that causes a lot of problems with
475 the way umount was originally written.
476 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
477 to be more consistent with sysvinit
478 * Changes to init.c to use the new -r option to umount. Also increased
479 the sleep time between the time the TERM and KILL signals are sent
484 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
485 extensively rewritten from the original cp.c.
486 * Fixed cp and mv so if the source and destination are a the
487 same directory it will print an error and continue.
488 * Also added a warning message to the `mv' usage string saying that
489 this is not GNU mv, and it will break hard links. cp also breaks
491 * ln.c: implemented `-n' switch, no-deref symlinks.
492 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
493 * name buffer overrun guards to prevent future crashes.
494 - Always check exit status.
495 - Purge all use of `creat()', replace with `open()'.
497 - recursiveAction was overriding the value of followLinks thus
499 - isDirectory now takes a followLinks boolean, updated all callers
500 - copyFile had the followLinks logic reversed.
501 * messages.c: New file. Put common error message strings all in
502 one place in an attempt to shrink the binary a little.
507 * changed fsck_minix.c to reduce its .bss size significantly
509 * Made tar creation support in busybox tar optional. You no longer
510 * _have_ to put a "-" in front of tar options. Tar could inadvertently
511 * change permissions and ownership on
512 certain directories pointed to by symlinks.
513 * Made grep and grep -h do the right thing wrt printing
514 the file name (it failed to print files names in many cases).
515 * Fix a namespace aliasing problem wereby if du was built in, the
516 symlink for both du and dutmp would be installed, or then rm was
517 built in, the symlinks for both rm and rmmod would be installed.
518 * Added a closelog() to init.c after loging -- fix thanks to
519 Taketoshi Sano <kgh12351@nifty.ne.jp>
520 * Rewrote and simplified logger. Added the "-t" option, and made it
521 behave itself a bit better.
522 * Optional support contributed by Ben Collins <bcollins@debian.org>
523 for the kernel init chroot patch by Werner Almesberger, which
524 allows init to chroot to a new device, and umount the old one.
525 * Fixed bug that wouldn't let one chown a symlink -- it would
526 always dereference before. -beppu
527 * Fixed a bug where init could have reference already freed memory.
528 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
529 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
530 * Added (and documented) "-n" option for head
531 * Cleanup for a number of usage messages -- also
532 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
533 * Cosmetic fix to busybox.c (Don't print a comma at the
534 end of line if there are no more application names).
535 * Fixed a stupid bug in "head" option handling ("head -n"
537 * Moved commonly used functions "xmalloc()" and "exit()"
538 to utility.c (with proper #ifdef's).
539 * Created a tiny tail implementation, removing -c, -q, -v, and making
540 tail -f work only with a single file. This reduced tail from 6k to
541 2.4k. The bigger/more featured tail can still be had by disabling
542 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
543 * Ping now falls back to doing the right thing if /etc/protocols
545 * Fixed mount and umount. Previously they could leak loop device
546 allocations, causing the system to quickly run out. Fix for umount
547 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
548 * ls formatting on eight charactor user names fixed by
549 Randolph Chung <tausq@debian.org>.
550 * cp could, when copying symlinks, change permissions of the
551 files pointed to by the symlinks.
552 * Several fixes from Pavel Roskin <proski@gnu.org>:
553 - `chown' with 1 argument displayed the error incorrectly
554 - `fdflush', `length' and `printf' crashed if run without arguments
555 - `fdflush' tried to flush itself using *argv
556 - added "skip" and "seek" to dd.
557 - ls no longer messus up output when combining files and
558 directories on the command line
559 * swapoff -a was not working. Now it is.
560 * init did not cleanly unmount filesystems on reboot. Now it does.
561 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
563 * Some architectures (PowerPc) assume chars are unsigned, so they could
564 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
565 * Began converting error handling to use some common routines
567 * syslogd now has better message handling and ignores SIGHUP.
568 * install.sh had a bug preventing installation to the specified
569 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
570 * You can now spefify alternative strip commands -- change
571 also from Gilbert Coville.
577 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
578 by Edward Betts <edward@debian.org>
579 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
580 type commands (file in a directory to another directory) from
582 * Fixed a logger bug that caused garbage to be written to the syslog
583 (unless you used busybox syslog, which hid the bug). Thanks to
584 Alex Holden <alex@linuxhacker.org> for the fix.
585 * /bin/true and /bin/false were echoing a blank line when run.
587 * mkdir -p would print an error when asked to mkdir an existing dir
588 with no interveining subdirectories.
589 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
590 * and support in umount for loop
591 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
592 <bcollins@debian.org>
593 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
594 * fullWrite() not only if BB_TAR is defined, but also
595 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
596 * add some compiler optimizations to further reduce executable size
597 (as a side note, on my machines the largest code is generated
598 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
600 * Compile now won't fail if busybox.def.h defines
601 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
602 referenced, but not compiled)
603 * Fixed a bug in setting TERM for serial console support. TERM now
604 defaults to "ansi" for serial consoles.
605 * Fixed a bug in handling the CONSOLE env. variable for serial
608 -Erik Andersen, Jan 15, 2000
611 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
612 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
613 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
614 for loading application character maps for Unicode fonts.
615 * Major init re-work. init now supports inittab (slightly different
616 but similar to sysvinit), allowing me to get all the policy out of
617 init and into the conf file. It works just fine without inittab
618 being present, but if you dont like the default behavior you can
619 now do something about it. Init is much cleaner as a result.
620 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
621 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
622 * failure of 'logger -p'. -erik Added the -s option to du -beppu
623 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
624 with the 2.0.x Linux kernel.
625 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
627 * Grep -i previously failed on UPPER CASE patterns due to a silly
628 regexp implementation bug that is now fixed.
629 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
630 * Fixed a bug where tar would not set the user and group on device
632 * Fixed a bug where tar would not restore the time to files. Fixed a
633 * major security problem with tar -- it changed ownership
634 of any file pointed to by a symlink to 777 (like say libc....)
636 * cp and mv were very broken when moving directories. I have rewritten
637 them so they should now work as expected.
638 * sed now supports addresses (numeric or regexp, with negation) and
639 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
640 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
641 * Some cosmetic fixes to ls output formatting to make it behave more
643 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
644 * <fwv@myrtle.lahn.de>:
645 - Added gunzip -t, removed gunzip.c dead code,
646 - fixed several typos
647 - Glibc 2.0.7 and libc5 compile fixes
648 * Fixed a bug where 'mknod --help' would segfault.
651 -Erik Andersen, Jan 07, 2000
654 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
655 <tausq@debian.org>. 3 items off the TODO list!
656 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
657 * tail from GNU textutils-1.19, but adjusted
658 to suit my evil purposes. Costs 6k. I'll make it smaller
660 * on reboot, init called 'umount -a -n', which caused errors
661 when BB_MTAB was not enabled. Changed to 'umount -a', which does
663 * init will now try to run /sbin/getty if it is present (for easy
664 integration with the about-to-be-released tinylogin.)
665 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
666 * -l' was failing on long directories, since my_getid was leaking
667 one file descriptor per file. Oops.
668 * Fixed rebooting from init. I'd accidently left some debugging code
670 which blocked reboots.
671 * Fixed reboot, halt (and added poweroff) such that they handle it when
672 init is not at PID 1 (like when running in an initrd).
673 * Added a prelinary du implementation. Some parameter parsing
674 stuff still needs to be added. -beppu (John Beppu
676 * Implemented tee. -beppu Implemented head. -beppu
678 -Erik Andersen, Dec 10, 1999
681 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
683 * df will not exit on error, but will stat all mounted filesystems.
684 * Fixed tar so uid/gid/permissions on extracted tarballs will be
686 * Fixed find -name so it properly uses shell wildcard patterns
687 (i.e. `*', `?', and `[]') instead of regular expressions, which
688 was causing some confusing and unexpected behavior.
689 * Added klogd to syslogd, so now the log will contain both system and
691 * syslogd now creates the /dev/log socket to make sure it is there, and
692 is actually a socket with the right permissions.
693 * I've taken a first step to making busybox not need the /proc
694 filesystem. Most apps don't need it. Those that _require_ it,
695 will complain if you enable them when you disable
696 BB_FEATURE_USE_PROCFS.
698 -Erik Andersen, Dec 5, 1999
701 * Wrote a micro syslogd, and a logger util (to log things to the syslog
702 from the command line or scripts) With both compiled in, costs 4k.
703 * Fixed 'make install' so symlinks are installed in their proper
704 * locations. Changed the build system slightly so that features can
706 or disabled from the busybox.defs.h header file, without trying to
707 compile in a source file named after that featue (unless that file
709 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
710 * -r' both work. dd now properly handles input beyond 1 block from
711 * stdin. Fixed a bug where tar unpacked everything a directories.
713 from createPath into mkdir where it belonged, thereby making tar
715 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
717 last file in the list.
718 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
720 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
721 are presented properly.
725 -Erik Andersen, Nov 25, 1999
728 * fixed dd so it properly defaults to stdin and stdout when no
729 if= and of= are set (fix thanks to Eric Delaunay).
730 * Don't try to close the file descriptor of a pipein tar. (fix also
733 * Made createPath be quiet (again thanks to Eric Delaunay). If
734 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
735 command you define it as will be run if the init script exits.
736 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
737 * NFS support added to mount by Eric Delaunay. It costs 10k when
739 in, but that is still a big win for those that use NFS.
740 * Made 'rm -f' be silent for non-existant files (thanks to Eric
741 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
743 and acts as god intended gunzip and zcat to act. They answer
744 --help and obey the '-c' flag.
745 * Fixed a bug in mv which caused it to not move files when the
748 * Fixed a decimal-instead-of-octal bug causing mkdir to make
750 with very wrong permissions.
751 * chmod would overwrite file permissions instead of modifying them.
752 Now it properly modifies permissions.
753 * Init now sends warnings destined for the console to /dev/console to
755 they show up on whatever the active console it. Otherwise
756 important messages (for example that the system is rebooting) were
757 not seen when switched to a different VT.
759 -Erik Andersen, Nov 17, 1999
762 * gzip now obeys the principle of least surprise and acts like god
764 (i.e. it accepts a file name, answers --help, and obeys the '-c'
765 flag and only then outputs to stdout).
766 * Fixed more.c to compile autowidth on sparc and set initial winsize
767 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
769 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
770 * tar now accepts --help chmod, chown, and chgrp usage now works
771 * General usage (i.e. --help) cleanups for most apps umount now parses
772 * options correctly tar can now unpack tarballs containing device
774 sockets, and fifos (though it can't pack them up) thanks to Matt
775 Porter. Creating archives containing these is still left to the
777 * fixed up the license in more.c to properly point to Bruce Perens.
779 -Erik Andersen, Nov 11, 1999
782 * ls -l now displays link names outside the current directory,
783 Patch thanks to Eric Delaunay
784 * init now properly handles sparc serial consoles and does a
785 better job of finding the real console device rather than using
786 /dev/console which doesn't support job control. Patch also thanks
788 * more started to read from stdin after the last file was finished, and
789 options were not parsed correctly (fix thanks to Eric Delaunay).
790 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
791 * rm wouldn't remove a symlink unless the symlink was valid. This was
792 a side effect of the busybox 0.32 recursiveAction() fix. Things
793 should now work correctly.
794 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
795 * it does. sed was appending a \n to the end of lines with
797 Now it doesn't do that.
798 * ls -l now bypasses libc6 nss when displaying user/group names.
799 Now uses my_getpwuid and my_getgrgid.
801 -Erik Andersen, Nov 8, 1999
804 * Fixed a bug where init could hang instead of rebooting.
805 * Removed some debugging noise from init.c
806 * Fixed ln so it works now (it was very broken).
807 * Fixed df so it won't segfault when there is no /etc/fstab,
808 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
809 is not installed (since they cannot fixup "/dev/root" to
810 state the real root device name)
811 * merged some redundant code from mtab.c/df.c into utility.c
813 -Erik Andersen, Nov 5, 1999
816 * More changes -- many thanks to Lineo for paying me to work on
817 busybox. If you have any problems please let me know ASAP at
818 andersen@lineo.com or andersee@debian.org
819 * usage() now prints the BusyBox version. This will help folks
820 realize that they are not in Kansas anymore.
821 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
822 * arguments. Now it doesn't do that. kill wasn't properly accepting
823 * signal names. It does now. Added new apps chvt and deallocvt (I
824 * should probably add open) Major rewrite of init.c. Code is now
825 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
826 * with full regular expressions!). Fixed a stupid seg-fault in sync
827 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
828 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
829 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
830 * cost of ~1.5k and the need for a rw /etc)
831 folks to use a real /etc/mtab file instead of a symlink to
832 /proc/mounts. mount, and umount will add/remove entries and df
833 will now use /etc/mtab if BB_MTAB is defined.
834 * Fixed a nice bug in recursiveAction() which caused it to infinitely
835 hunt through /proc/../fd/* creating new file descriptors if it
836 followed the /dev/fd link over to /proc. recursiveAction() now
837 lstat's the file when followLinks==FALSE so it won't follow links
838 as the name suggests. Fix thanks to Matt Porter
842 -Erik Andersen, Nov 4, 1999
845 * I added a changelog for version 0.30. adjusted find internals to
846 * make it smaller, and removed
848 * Fixed a segfault in ps when /etc/passwd or /etc/group
849 are absent. Now will warn you and carry on.
850 * Added in optional _real_ regular expression support (to be
851 the basis for a future sed utility). When compiled in it adds
852 3.9k, but makes grep much more capable.
853 * Checked out using nftw(3) for recursive stuff, but unfortunatly
854 it wasn't supported before GNU libc 2.1, and some folks use glibc
855 2.0.7 since it is much smaller than that latest and greatest.
857 -Erik Andersen, Oct 21, 1999
860 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
861 paying me to make these updates. If you have any problems with busybox,
862 or notice any bugs -- please let me know so I can fix it. These
866 * busybox can now invoke apps in two ways: via symlinks to the
867 busybox binary, and as 'busybox [function] [arguments]...'
868 * When invoked as busybox, the list of currently compiled in
869 functions is printed out (no this is not bloat -- the list has
870 to be there anyway to map invocation name to function).
871 * busybox no longer parses command lines for apps or displays their
872 usage info. Each app gets to handle (or not handle) this for
874 * Eliminated monadic, dyadic, descend, block_device, and
875 postprocess. It was cumbersome to have so many programs
876 cobbled together in this way. Without them, the app is much
878 * All shared code now lives in utility.c, and is properly
879 ifdef'ed to be only included for those apps requiring it.
880 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
881 so now each app has the function prototype of (da-dum): extern
882 int foo_main(int argc, char** argv); which speeds integration
884 * Adjusted the Makefile to make it easier to
885 {en|dis}able debugging.
886 * Changed default compiler optimization to -Os
887 (optimize for smaller binaries).
890 * To cope with the new app function prototype and the removal of
891 monadic, dyadic, etc, the following apps were re-written:
892 * cat - Works same as always. chgrp, chmod, chown -
893 * rewrite. Combined into a single
894 source file. Absorbed patches from Enrique Zanardi
895 <ezanard@debian.org> that removes the dependency on
896 libc6 libnss* libraries.
897 * cp - Can now do 'cp -a' can can copy devices,
898 pipes, symlinks, as well as recursive or non-recursive
900 * fdflush - adjusted to remove dependancy on struct
901 * FileInfo. find - Now includes some basic regexp matching
902 which will be the basic of a future mini-sed.
903 * ln - Same functionality. mkdir - Added -p flag to
904 * feature set. mv - rewrite. rm - Added -f flag to
905 * feature set. rmdir - Same functionality. swapon,
906 * swapoff - Combined into a single binary. No longer
907 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
909 * touch - Same functionality. date - adjusted with a patch
910 * from Matthew Grant <grantma@anathoth.gen.nz>
911 to accomodate glibc timezone support. I then ripped out GNU
913 * mkswap -- new version merged from util-linux. Can now make
915 * Replaced the old and star, unstar, and tarcat with the tar
916 implementation from sash. Now tar behaves as god intended it
917 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
918 * dd -- rewritten. Can with with files, stdin, stdout. Added the
919 * following new apps: loadfont -- added from debian boot floppies
920 * chroot -- added based on a patch from Paolo Molaro
921 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
922 * simple strings ps -- I just wrote it. Has _no_ options at all,
923 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
925 internationalization and such to make them smaller.
926 * sfdisk -- Added from util-linux (minus
927 * internationalization and such). Probably some other
928 * changes that I forgot to document...
930 -Erik Andersen, Oct 20, 1999
933 This version was a messy pre-alpha. stay away or it will bite you.
934 -Erik Andersen, Sep 24, 1999
937 mini-netcat (mnc) rewritten.
940 Mount now supports -a, and -t auto.
941 Mount now updates mtab correctly for 'ro'.
942 More checks screen rows size, outputs bytes percentage.
943 Printf added as module.
945 Touch now creates files. -c option for no create.
