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