31 Better if-then-else-fi handling
32 * Erik Andersen -- cleaner division of labor between cmdedit.c and sh.c
33 * Erik Andersen -- md5sum was broken in 0.48. Now fixed (and doesn't
34 use getline, shrinking static compiles (since nothing else used it).
35 * Mark Whitley -- Updates to style guide
36 * Mark Whitley -- Big cleanup in utility.c: style guide compliance,
37 de-macro-ifying some variables and functions
40 -Erik Andersen, <not released yet>
44 * Glenn McGrath -- tar now supports uncompressing tar files,
45 define BB_FEATURE_TAR_GZIP to use the -z option.
46 * Matt Kraai -- fix all usage of TRUE and FALSE so all apps now
47 return EXIT_SUCCESS or EXIT_FAILURE to the system.
48 Now TRUE and FALSE are set to the C standard where TRUE=1.
49 * me -- Fixed uname problem causing the kernel version to be
50 mis-detected (causing problems with poweroff, init,
52 * Alcove, Julien Gaulmin <julien.gaulmin@alcove.fr> and
53 Nicolas Ferre <nicolas.ferre@alcove.fr> -- insmod support on ARM
54 and StrongArm, and suport for lsmod on older 2.0.x kernels.
55 * Kent Robotti -- Renamed unrpm to original rpmunpack, so you can use
56 an included shell script called unrpm as a front end to it. There's
57 also a shell script called undeb included for debian packages.
58 * Matt Kraai -- fix an infinite loop with ls -aR
59 * Larry Doolittle -- Shaved off about 100 bytes and 200 bytes heap
60 from date.c. Also document the "-d" option in the usage message.
61 * Gennady Feldman -- fixed dd to use blocksize when reading/writing,
62 (it was reading the whole thing and then writing it out). Also
63 updated usage information (was missing conv=notrunc) and added
65 * Larry Doolittle (in collaboration with Matt Kraai) -- allow for a
66 pristine source directory -- where all the .o files and such are
67 not placed into the source tree. Thanks Larry!
68 * Larry Doolittle -- use the applet definitions in applets.h
69 to autogenerate the applet function and usage prototypes.
70 * Sebastien Huet, Arne Bernin, and Kent Robotti -- Add in tar -X and
71 fixed a bug breaking tar --exclude.
72 * Jonas Holmberg -- echo option handling made GNU-echo compatible
73 * Aleksey Demidov <asd@ixcelerator.com> -- date option handling made
75 * me -- Progress meter (optional) in wget
76 * Doolittle/me -- programs invoked by full path name take
77 precedence over applets unless BB_FEATURE_SH_BUILTINS_ALWAYS_WIN
78 * Gaute B Strokkenes <gs234@cam.ac.uk> -- applets found using a
79 binary search instead of linear search. Much faster!
80 * new applets: cmp readlink
81 * Mark Whitley -- Removed advertising clause of Berkeley license
82 according to decision by the Regents of the University of
83 California; included reference
84 * tail's confusing special treatment of single digit options removed;
85 people should use -n instead
86 * Larry Doolittle -- \r handled now in echo and tr
87 * Matt Kraai -- rewrite of uniq
88 * Mark Whitley -- remix of xargs

95 * various artists -- Other good stuff that I forgot to document.
98 -Erik Andersen, 13 December 2000
102 * A bug in syslogd was fixed that allowed it to potentially fork-bomb
103 your system. Anyone using 0.46 syslogd should upgrade.
104 * Renamed busybox.defs.h to the more sensible "Config.h"
105 * Improved portability between different libcs.
106 * Many apps ported to use getopt()
107 * Common handling of '--help'
108 * All usage messages centralized.
109 * Added a bunch of new commands:
110 * 'rdate' contributed by Sterling Huxley <sterling@europa.com>
111 * 'wget' contributed by Chip Rosenthal <chip@unicom.com>,
112 <crosenth@covad.com> and Covad Communications
113 * 'getopt' from "Alfred M. Szmidt" <ams@trillian.itslinux.org>
114 * dos2unix, unix2dos, reset, and unrpm.c (and lots of help
115 debugging) thanks to Kent Robotti <robotti@metconnect.com>.
116 * 'renice' command, thanks to Dave Cinege <dcinege@psychosis.com>
117 * 'xargs' (written by me)
118 * 'expr' contributed by Edward Betts <edward@debian.org>, based
120 * lsmod now uses the query_module syscall, rather then /proc (me)
121 * syslogd can now log messages to remote hosts -- patch thanks
122 to Gyepi Sam <gyepi@praxis-sw.com>
123 * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>
124 * 'make install' now creates relative symlinks, and added a new
125 'make install-hardlinks' target to (tada) install hardlinks.
126 * Rewrite of 'tail' to make it simpler, smaller, and more robust.
127 It now weighs only 2.25k (3k when full featured). The code is
128 cleaner too, thanks to Allen Soard <esp-software@mail.hypermart.net>
129 * Add optional ls file sorting, thanks to a patch from
130 Sterling Huxley <sterling@europa.com>
131 * Fixed chmod option parsing so things like 'chmod -r /tmp/file'
132 now work (previously it thought -r was an option). Doh!
133 * Fixed tar handling of stdin and stdout
134 * Renamed "internal.h" to the more sensible "busybox.h"
135 * Preliminary support for GNU HURD.
136 * Updated my devps and devmtab kernel patches for the latest 2.2.x
137 kernel, for those wanting to go proc-less.
138 * Tons of other bugfixes.
141 -Erik Andersen, 25 September 2000
146 * Better portability. Now should compile cleanly with libc5,
147 GNU libc 2.0 and 2.1, and various Linux kernels including
148 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
149 to make /proc/mounts behave included in the kernel-patches dir).
150 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
151 local files that matched tarball contents!!! Fix thanks
152 to Marius Groeger <mgroeger@sysgo.de>
153 * Fixed a nasty bug in tar when could mess up saved symlinks.
154 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
155 thanks to Daniel Quinlan <quinlan@transmeta.com>
156 * Updates to handle Linux 2.4.0 kernels (kludged around the
157 "none" entries in /proc/mounts, added a hack to make sysinfo
158 work with both old and new kernels).
159 * Fixed insmod module option parsing for options lacking an '='.
160 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
161 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
162 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
163 * Several fixes from Marius Groeger <mag@sysgo.de>
164 - Added support for "sh -c command args..."
165 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
166 - Added shell environment variable substitution
167 - Added the "read" shell builtin.
168 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
169 used to create an infinite loop: ls, cursor up, left, down.
170 * Added support for being a login shell, so things like
171 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
172 invoke the shell. Now you can use BusyBox as a login shell.
173 * ls.c now ignores '-g', since some ftp clients like that sort
174 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
175 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
176 it always sets the controlling terminal before running any programs
177 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
178 - Fixed tr so it recognizes standard escape sequences.
179 Merged common escape seq. code from tr and echo into utility.c.
180 - Major work in updating/cleaning up the docs, and getting the
181 new SGML based docs into shape.
183 - BusyBox should now poweroff when asked to do so.
184 - Fixed 'ln -n' and 'ln -s' so they both work properly.
185 * Reorganized signal names in kill.c for better architecture support
186 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
187 * In 0.43, backspace and delete worked properly, but with 0.45,
188 it just echoed a ^? for backspace, and ^H for control-h. This
189 was due to a broken macro in init.c, that is now fixed.
190 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
191 couldn't maintain it very well, so including it was not really
192 very appropriate. Those wanting an fdisk are invited to
193 grab a copy from util-linux.
194 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
195 then be loaded in by 'loadkmap' -- submitted by
196 Arne Bernin <arne@matrix.loopback.org>
197 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
198 * Brand, new versions of grep and sed which use libc regex routines,
199 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
200 "regexp.[ch]" files have been removed. Much help on these from
204 -Erik Andersen, 11 July 2000
208 * Now compiles vs libc5 (which can save lots of space for
210 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
211 help messages (i.e --help). Saves 17k over a full compile.
212 * Added cut and tr from minix, since due to the license change,
213 we can now use minix code. Minix tr saves 4k.
214 * insmod now works. It costs 29k, but imagine an initrd with a
215 staticly linked busybox containing only insmod and sh, a few /dev
216 entries, and a kernel module or two... It doesn't get smaller
217 then this folks (I pity the fool that writes insmod in asm ;-).
218 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
219 * Added a mini ar archive utility, especially written for BusyBox by
220 Glenn McGrath <bug1@netconnect.com.au>
221 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
222 * Added setkeycodes, for those that have wierd keyboard buttons.
223 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
224 <ams@trillian.itslinux.org> for contributing these.
225 * Added 'grep -v' option (inverted search) and updated
226 docs accordingly. -beppu
228 * Replaced the telnet implementation with one written by
229 Tomi Ollila <too@iki.fi> It works great and costs 3k.
230 * BusyBox sh (lash) now supports being used as a standalone shell. When
231 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
232 be invoked as shell internals. Best used when compiling staticly
234 * BusyBox sh (lash) internals now behave as expected wrt pipes
236 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
237 * Fixed update segfault
238 * Fixed mknod -- minor number was always 0
239 * Fixed tar option parsing, so both "tar xvf foo.tar" and
240 "tar -xvf foo.tar" now work (i.e. no "-" before options)
241 (this was very broken in 0.43).
242 * Several contributions from Randolph Chung <tausq@debian.org>.
243 * cp/mv now accepts the -f flag
244 * tail can now accept -<num> commands (e.g. -10) for better
245 compatibility with the standard tail command
246 * added a simple id implementation; doesn't support sup. groups yet
247 * logname used getlogin(3) which uses utmp. Now it doesn't.
248 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
249 * Add support for "noatime" and "nodiratime" mount flags to mount.
250 * Changed 'umount -f' to mean force, and actually use umount2.
251 * Changed 'umount -l' to mean "Do not free loop device".
252 * Fixed basename to support stripping of suffixes. Patch thanks
253 to xiong jianxin <jxiong@uiuc.edu>
254 * cp -fa now works as expected for symlinks (it didn't before)
255 * zcat now works (wasn't working since option parsing was broken)
256 * Renamed "mnc" to the more correct "nc" (for netcat).
257 * Makefile intelligence updates
258 * Changed the way init parses /etc/inittab entries to avoid problems
259 with commands that contain colons in them. Fix thanks to
260 Pavel Roskin <proski@gnu.org>
261 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
262 Fix thanks to Pavel Roskin <proski@gnu.org>
263 * Made "killall" complain (not error and exit) about processes that it
264 cannot find by name -- Pavel Roskin <proski@gnu.org>
265 * Fixed more and ps to have sensible terminal width defaults, thanks
267 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
268 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
269 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
270 * Fixed segfault caused by "touch -c"
271 * Fixed segfault caused by "rm -f"
272 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
273 and "--" support from Pavel Roskin.
274 * Fixed segfault caused by "cp -a -a" and similar abuses.
275 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
276 * "which" rewritten to use stat(). Fixes to improve its compatability
277 with traditional implementations -- Pavel Roskin.
278 * "mount" now reports errors from nfsmount() and assumes NFS mount
279 if ':' is present in the device name - Pavel Roskin
280 * Fixed exit status for killall - Pavel Roskin
281 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
282 * Fixed 'mount -a' so it works as expected.
283 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
284 * Implemented "ping -s", fixed error messages and argument parsing -
286 * Syslogd will not go to background if "-n" is given. Better help
287 and argument checking -- Pavel Roskin
288 * Fixed a small bug that could cause tar to emit warning messages
289 and not extract the first file in a directory in some cases
290 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
291 for helping track this one down.
293 * Fixed grep "Line too long" problem -- John Beppu
294 * Fixed 'grep -q -i B some_file' so it works
295 * math takes input from stdin if no args are given. -- John Beppu
296 * math was renamed to dc. Although it deviates from dc's behaviour,
297 this will probably be remedied in the future. -- John Beppu
300 -Erik Andersen, June 21, 2000
304 Previously, an erronous announcement of BusyBox 0.44 was made, so to
305 avoid possible confusion, we are skipping straight to 0.45, and calling
312 * Major update to the provided documentation.
313 * Busybox now includes a shell! It currently costs 7.5 k (plus an
314 additional 2.5 k if you compile in command line editing). Handles
315 job control, has the usual set of builtins, and does everything
316 except for handling programming statements (if, while, etc...)
317 * Busybox can now work perfectly when /proc is disabled, thereby
318 saving a bunch of memory (kernel /proc support is not thin). This
319 is done by making use of some nice kernel patches I wrote up to
320 support the features that busybox requires and that /proc usually
321 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
322 patch your kernel with the devps patch in the kernel-patches/
324 * Wrote basename, dirname, killall, and uptime.
325 * tar has been completely rewritten by me. Both tar creation and
326 extraction are now well behaved. Costs 7.6k with all optional
327 tar features enabled, and 5k for just tar extraction support.
328 * Added freeramdisk, which will free up all memory associated
329 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
330 and then adjusted a bit by me.
331 * Added tr from John Lombardo <john@deltanet.com>
332 * Added echo and test (from me).
333 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
334 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
335 * Several fixes from Pavel Roskin <proski@gnu.org>:
336 - When `tail' fails to open a file it now exits.
337 - When `syslogd' is given the `-n' option it should still use
338 fork() for running klogd.
339 * nslookup types are now changed to u_int32_t (instead of uint32_t)
340 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
341 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
342 to count hard-linked files more then once). Many thanks to
343 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
344 * Removed /proc dependancies for init and free (while maintaining
345 exactly the same functionality). /proc takes up 90k of kernel
346 space, so it is nice to avoid using it at all costs.
347 * init no longer tries to mount /proc (unless there is less the 1 meg
348 free). Use of /proc (or not) is policy that should be set up in
349 /etc/fstab (or in hardcoded scripts), not in init.
350 * Fixed rebooting when init runs as an initrd.
351 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
352 - update.c rewritten to look more like update-2.11
353 - moveed the inode hash out of du.c and into utility.c to make
354 it a common resource that can be used by other apps.
355 - cp_mv.c now checks inodes to see if a source and dest are
356 the same, and prints an error (instead of endlessly looping).
357 - mv now attempts to do a rename, and will fall back to doing
358 a copy only if the rename fails.
359 - Syslogd now supports multiple concurrent connections
360 * Several fixes from Pavel Roskin <proski@gnu.org>:
361 - Fixes to sort. Removed "-g", fixed and added "-r"
362 - Fixes to the makefile for handling "strip"
363 * An initial telnet implementation was added by
364 Randolph Chung <tausq@debian.org>.
365 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
366 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
367 to match the terminal (defaults to width=79 when this is off).
368 * ps now accepts (and ignores) all options except for "--help" (which
369 as would be expected displays help).
370 * Fixed mount'ing loop devices when the filesystem type was not
371 specified. It used to revert to non-loop after the first try.
372 * all mallocs now use xmalloc (and so are OOM error safe), and
373 the common error handling saves a few bytes. Thanks to
374 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
375 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
376 * Fix symlink following bug in chmod -R and friends.
377 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
378 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
387 * Fairly massive restructuring of umount.c to deal with remounting
388 busy devices read-only. Adds a -r option to control that; it is
389 optionally compiled in with BB_FEATURE_REMOUNT
390 * Added a bunch of functions to mtab.c to interact with the
391 {get,set,end}mntent interface; as it turns out, those functions do
392 not appear to be re-entrant, and that causes a lot of problems with
393 the way umount was originally written.
394 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
395 to be more consistent with sysvinit
396 * Changes to init.c to use the new -r option to umount. Also increased
397 the sleep time between the time the TERM and KILL signals are sent
402 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
403 extensively rewritten from the original cp.c.
404 * Fixed cp and mv so if the source and destination are a the
405 same directory it will print an error and continue.
406 * Also added a warning message to the `mv' usage string saying that
407 this is not GNU mv, and it will break hard links. cp also breaks
409 * ln.c: implemented `-n' switch, no-deref symlinks.
410 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
411 * name buffer overrun guards to prevent future crashes.
412 - Always check exit status.
413 - Purge all use of `creat()', replace with `open()'.
415 - recursiveAction was overriding the value of followLinks thus
417 - isDirectory now takes a followLinks boolean, updated all callers
418 - copyFile had the followLinks logic reversed.
419 * messages.c: New file. Put common error message strings all in
420 one place in an attempt to shrink the binary a little.
425 * changed fsck_minix.c to reduce its .bss size significantly
427 * Made tar creation support in busybox tar optional. You no longer
428 * _have_ to put a "-" in front of tar options. Tar could inadvertently
429 * change permissions and ownership on
430 certain directories pointed to by symlinks.
431 * Made grep and grep -h do the right thing wrt printing
432 the file name (it failed to print files names in many cases).
433 * Fix a namespace aliasing problem wereby if du was built in, the
434 symlink for both du and dutmp would be installed, or then rm was
435 built in, the symlinks for both rm and rmmod would be installed.
436 * Added a closelog() to init.c after loging -- fix thanks to
437 Taketoshi Sano <kgh12351@nifty.ne.jp>
438 * Rewrote and simplified logger. Added the "-t" option, and made it
439 behave itself a bit better.
440 * Optional support contributed by Ben Collins <bcollins@debian.org>
441 for the kernel init chroot patch by Werner Almesberger, which
442 allows init to chroot to a new device, and umount the old one.
443 * Fixed bug that wouldn't let one chown a symlink -- it would
444 always dereference before. -beppu
445 * Fixed a bug where init could have reference already freed memory.
446 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
447 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
448 * Added (and documented) "-n" option for head
449 * Cleanup for a number of usage messages -- also
450 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
451 * Cosmetic fix to busybox.c (Don't print a comma at the
452 end of line if there are no more application names).
453 * Fixed a stupid bug in "head" option handling ("head -n"
455 * Moved commonly used functions "xmalloc()" and "exit()"
456 to utility.c (with proper #ifdef's).
457 * Created a tiny tail implementation, removing -c, -q, -v, and making
458 tail -f work only with a single file. This reduced tail from 6k to
459 2.4k. The bigger/more featured tail can still be had by disabling
460 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
461 * Ping now falls back to doing the right thing if /etc/protocols
463 * Fixed mount and umount. Previously they could leak loop device
464 allocations, causing the system to quickly run out. Fix for umount
465 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
466 * ls formatting on eight charactor user names fixed by
467 Randolph Chung <tausq@debian.org>.
468 * cp could, when copying symlinks, change permissions of the
469 files pointed to by the symlinks.
470 * Several fixes from Pavel Roskin <proski@gnu.org>:
471 - `chown' with 1 argument displayed the error incorrectly
472 - `fdflush', `length' and `printf' crashed if run without arguments
473 - `fdflush' tried to flush itself using *argv
474 - added "skip" and "seek" to dd.
475 - ls no longer messus up output when combining files and
476 directories on the command line
477 * swapoff -a was not working. Now it is.
478 * init did not cleanly unmount filesystems on reboot. Now it does.
479 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
481 * Some architectures (PowerPc) assume chars are unsigned, so they could
482 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
483 * Began converting error handling to use some common routines
485 * syslogd now has better message handling and ignores SIGHUP.
486 * install.sh had a bug preventing installation to the specified
487 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
488 * You can now spefify alternative strip commands -- change
489 also from Gilbert Coville.
495 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
496 by Edward Betts <edward@debian.org>
497 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
498 type commands (file in a directory to another directory) from
500 * Fixed a logger bug that caused garbage to be written to the syslog
501 (unless you used busybox syslog, which hid the bug). Thanks to
502 Alex Holden <alex@linuxhacker.org> for the fix.
503 * /bin/true and /bin/false were echoing a blank line when run.
505 * mkdir -p would print an error when asked to mkdir an existing dir
506 with no interveining subdirectories.
507 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
508 * and support in umount for loop
509 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
510 <bcollins@debian.org>
511 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
512 * fullWrite() not only if BB_TAR is defined, but also
513 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
514 * add some compiler optimizations to further reduce executable size
515 (as a side note, on my machines the largest code is generated
516 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
518 * Compile now won't fail if busybox.def.h defines
519 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
520 referenced, but not compiled)
521 * Fixed a bug in setting TERM for serial console support. TERM now
522 defaults to "ansi" for serial consoles.
523 * Fixed a bug in handling the CONSOLE env. variable for serial
526 -Erik Andersen, Jan 15, 2000
529 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
530 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
531 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
532 for loading application character maps for Unicode fonts.
533 * Major init re-work. init now supports inittab (slightly different
534 but similar to sysvinit), allowing me to get all the policy out of
535 init and into the conf file. It works just fine without inittab
536 being present, but if you dont like the default behavior you can
537 now do something about it. Init is much cleaner as a result.
538 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
539 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
540 * failure of 'logger -p'. -erik Added the -s option to du -beppu
541 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
542 with the 2.0.x Linux kernel.
543 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
545 * Grep -i previously failed on UPPER CASE patterns due to a silly
546 regexp implementation bug that is now fixed.
547 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
548 * Fixed a bug where tar would not set the user and group on device
550 * Fixed a bug where tar would not restore the time to files. Fixed a
551 * major security problem with tar -- it changed ownership
552 of any file pointed to by a symlink to 777 (like say libc....)
554 * cp and mv were very broken when moving directories. I have rewritten
555 them so they should now work as expected.
556 * sed now supports addresses (numeric or regexp, with negation) and
557 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
558 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
559 * Some cosmetic fixes to ls output formatting to make it behave more
561 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
562 * <fwv@myrtle.lahn.de>:
563 - Added gunzip -t, removed gunzip.c dead code,
564 - fixed several typos
565 - Glibc 2.0.7 and libc5 compile fixes
566 * Fixed a bug where 'mknod --help' would segfault.
569 -Erik Andersen, Jan 07, 2000
572 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
573 <tausq@debian.org>. 3 items off the TODO list!
574 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
575 * tail from GNU textutils-1.19, but adjusted
576 to suit my evil purposes. Costs 6k. I'll make it smaller
578 * on reboot, init called 'umount -a -n', which caused errors
579 when BB_MTAB was not enabled. Changed to 'umount -a', which does
581 * init will now try to run /sbin/getty if it is present (for easy
582 integration with the about-to-be-released tinylogin.)
583 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
584 * -l' was failing on long directories, since my_getid was leaking
585 one file descriptor per file. Oops.
586 * Fixed rebooting from init. I'd accidently left some debugging code
588 which blocked reboots.
589 * Fixed reboot, halt (and added poweroff) such that they handle it when
590 init is not at PID 1 (like when running in an initrd).
591 * Added a prelinary du implementation. Some parameter parsing
592 stuff still needs to be added. -beppu (John Beppu
594 * Implemented tee. -beppu Implemented head. -beppu
596 -Erik Andersen, Dec 10, 1999
599 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
601 * df will not exit on error, but will stat all mounted filesystems.
602 * Fixed tar so uid/gid/permissions on extracted tarballs will be
604 * Fixed find -name so it properly uses shell wildcard patterns
605 (i.e. `*', `?', and `[]') instead of regular expressions, which
606 was causing some confusing and unexpected behavior.
607 * Added klogd to syslogd, so now the log will contain both system and
609 * syslogd now creates the /dev/log socket to make sure it is there, and
610 is actually a socket with the right permissions.
611 * I've taken a first step to making busybox not need the /proc
612 filesystem. Most apps don't need it. Those that _require_ it,
613 will complain if you enable them when you disable
614 BB_FEATURE_USE_PROCFS.
616 -Erik Andersen, Dec 5, 1999
619 * Wrote a micro syslogd, and a logger util (to log things to the syslog
620 from the command line or scripts) With both compiled in, costs 4k.
621 * Fixed 'make install' so symlinks are installed in their proper
622 * locations. Changed the build system slightly so that features can
624 or disabled from the busybox.defs.h header file, without trying to
625 compile in a source file named after that featue (unless that file
627 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
628 * -r' both work. dd now properly handles input beyond 1 block from
629 * stdin. Fixed a bug where tar unpacked everything a directories.
631 from createPath into mkdir where it belonged, thereby making tar
633 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
635 last file in the list.
636 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
638 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
639 are presented properly.
643 -Erik Andersen, Nov 25, 1999
646 * fixed dd so it properly defaults to stdin and stdout when no
647 if= and of= are set (fix thanks to Eric Delaunay).
648 * Don't try to close the file descriptor of a pipein tar. (fix also
651 * Made createPath be quiet (again thanks to Eric Delaunay). If
652 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
653 command you define it as will be run if the init script exits.
654 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
655 * NFS support added to mount by Eric Delaunay. It costs 10k when
657 in, but that is still a big win for those that use NFS.
658 * Made 'rm -f' be silent for non-existant files (thanks to Eric
659 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
661 and acts as god intended gunzip and zcat to act. They answer
662 --help and obey the '-c' flag.
663 * Fixed a bug in mv which caused it to not move files when the
666 * Fixed a decimal-instead-of-octal bug causing mkdir to make
668 with very wrong permissions.
669 * chmod would overwrite file permissions instead of modifying them.
670 Now it properly modifies permissions.
671 * Init now sends warnings destined for the console to /dev/console to
673 they show up on whatever the active console it. Otherwise
674 important messages (for example that the system is rebooting) were
675 not seen when switched to a different VT.
677 -Erik Andersen, Nov 17, 1999
680 * gzip now obeys the principle of least surprise and acts like god
682 (i.e. it accepts a file name, answers --help, and obeys the '-c'
683 flag and only then outputs to stdout).
684 * Fixed more.c to compile autowidth on sparc and set initial winsize
685 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
687 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
688 * tar now accepts --help chmod, chown, and chgrp usage now works
689 * General usage (i.e. --help) cleanups for most apps umount now parses
690 * options correctly tar can now unpack tarballs containing device
692 sockets, and fifos (though it can't pack them up) thanks to Matt
693 Porter. Creating archives containing these is still left to the
695 * fixed up the license in more.c to properly point to Bruce Perens.
697 -Erik Andersen, Nov 11, 1999
700 * ls -l now displays link names outside the current directory,
701 Patch thanks to Eric Delaunay
702 * init now properly handles sparc serial consoles and does a
703 better job of finding the real console device rather than using
704 /dev/console which doesn't support job control. Patch also thanks
706 * more started to read from stdin after the last file was finished, and
707 options were not parsed correctly (fix thanks to Eric Delaunay).
708 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
709 * rm wouldn't remove a symlink unless the symlink was valid. This was
710 a side effect of the busybox 0.32 recursiveAction() fix. Things
711 should now work correctly.
712 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
713 * it does. sed was appending a \n to the end of lines with
715 Now it doesn't do that.
716 * ls -l now bypasses libc6 nss when displaying user/group names.
717 Now uses my_getpwuid and my_getgrgid.
719 -Erik Andersen, Nov 8, 1999
722 * Fixed a bug where init could hang instead of rebooting.
723 * Removed some debugging noise from init.c
724 * Fixed ln so it works now (it was very broken).
725 * Fixed df so it won't segfault when there is no /etc/fstab,
726 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
727 is not installed (since they cannot fixup "/dev/root" to
728 state the real root device name)
729 * merged some redundant code from mtab.c/df.c into utility.c
731 -Erik Andersen, Nov 5, 1999
734 * More changes -- many thanks to Lineo for paying me to work on
735 busybox. If you have any problems please let me know ASAP at
736 andersen@lineo.com or andersee@debian.org
737 * usage() now prints the BusyBox version. This will help folks
738 realize that they are not in Kansas anymore.
739 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
740 * arguments. Now it doesn't do that. kill wasn't properly accepting
741 * signal names. It does now. Added new apps chvt and deallocvt (I
742 * should probably add open) Major rewrite of init.c. Code is now
743 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
744 * with full regular expressions!). Fixed a stupid seg-fault in sync
745 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
746 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
747 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
748 * cost of ~1.5k and the need for a rw /etc)
749 folks to use a real /etc/mtab file instead of a symlink to
750 /proc/mounts. mount, and umount will add/remove entries and df
751 will now use /etc/mtab if BB_MTAB is defined.
752 * Fixed a nice bug in recursiveAction() which caused it to infinitely
753 hunt through /proc/../fd/* creating new file descriptors if it
754 followed the /dev/fd link over to /proc. recursiveAction() now
755 lstat's the file when followLinks==FALSE so it won't follow links
756 as the name suggests. Fix thanks to Matt Porter
760 -Erik Andersen, Nov 4, 1999
763 * I added a changelog for version 0.30. adjusted find internals to
764 * make it smaller, and removed
766 * Fixed a segfault in ps when /etc/passwd or /etc/group
767 are absent. Now will warn you and carry on.
768 * Added in optional _real_ regular expression support (to be
769 the basis for a future sed utility). When compiled in it adds
770 3.9k, but makes grep much more capable.
771 * Checked out using nftw(3) for recursive stuff, but unfortunatly
772 it wasn't supported before GNU libc 2.1, and some folks use glibc
773 2.0.7 since it is much smaller than that latest and greatest.
775 -Erik Andersen, Oct 21, 1999
778 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
779 paying me to make these updates. If you have any problems with busybox,
780 or notice any bugs -- please let me know so I can fix it. These
784 * busybox can now invoke apps in two ways: via symlinks to the
785 busybox binary, and as 'busybox [function] [arguments]...'
786 * When invoked as busybox, the list of currently compiled in
787 functions is printed out (no this is not bloat -- the list has
788 to be there anyway to map invocation name to function).
789 * busybox no longer parses command lines for apps or displays their
790 usage info. Each app gets to handle (or not handle) this for
792 * Eliminated monadic, dyadic, descend, block_device, and
793 postprocess. It was cumbersome to have so many programs
794 cobbled together in this way. Without them, the app is much
796 * All shared code now lives in utility.c, and is properly
797 ifdef'ed to be only included for those apps requiring it.
798 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
799 so now each app has the function prototype of (da-dum): extern
800 int foo_main(int argc, char** argv); which speeds integration
802 * Adjusted the Makefile to make it easier to
803 {en|dis}able debugging.
804 * Changed default compiler optimization to -Os
805 (optimize for smaller binaries).
808 * To cope with the new app function prototype and the removal of
809 monadic, dyadic, etc, the following apps were re-written:
810 * cat - Works same as always. chgrp, chmod, chown -
811 * rewrite. Combined into a single
812 source file. Absorbed patches from Enrique Zanardi
813 <ezanard@debian.org> that removes the dependency on
814 libc6 libnss* libraries.
815 * cp - Can now do 'cp -a' can can copy devices,
816 pipes, symlinks, as well as recursive or non-recursive
818 * fdflush - adjusted to remove dependancy on struct
819 * FileInfo. find - Now includes some basic regexp matching
820 which will be the basic of a future mini-sed.
821 * ln - Same functionality. mkdir - Added -p flag to
822 * feature set. mv - rewrite. rm - Added -f flag to
823 * feature set. rmdir - Same functionality. swapon,
824 * swapoff - Combined into a single binary. No longer
825 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
827 * touch - Same functionality. date - adjusted with a patch
828 * from Matthew Grant <grantma@anathoth.gen.nz>
829 to accomodate glibc timezone support. I then ripped out GNU
831 * mkswap -- new version merged from util-linux. Can now make
833 * Replaced the old and star, unstar, and tarcat with the tar
834 implementation from sash. Now tar behaves as god intended it
835 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
836 * dd -- rewritten. Can with with files, stdin, stdout. Added the
837 * following new apps: loadfont -- added from debian boot floppies
838 * chroot -- added based on a patch from Paolo Molaro
839 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
840 * simple strings ps -- I just wrote it. Has _no_ options at all,
841 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
843 internationalization and such to make them smaller.
844 * sfdisk -- Added from util-linux (minus
845 * internationalization and such). Probably some other
846 * changes that I forgot to document...
848 -Erik Andersen, Oct 20, 1999
851 This version was a messy pre-alpha. stay away or it will bite you.
852 -Erik Andersen, Sep 24, 1999
855 mini-netcat (mnc) rewritten.
858 Mount now supports -a, and -t auto.
859 Mount now updates mtab correctly for 'ro'.
860 More checks screen rows size, outputs bytes percentage.
861 Printf added as module.
863 Touch now creates files. -c option for no create.
