5 * Glenn McGrath -- new 'dpkg-deb' applet
6 * Glenn McGrath -- new ar code
7 * spoon -- new watchdog applet
8 * Vladimir N. Oleynik <dzo@simtreas.ru> -- fixed cmdedit.c so now
9 scrolling and tab completion in lash work properly. Also several
10 byte saving optimizations.
11 * Erik Andersen -- disabled many less commonly used applets by default
12 * Mark Whitley -- more thrashing about to get clean perror_msg usage
13 * Matt Kraai -- new command line munging
14 * Larry Doolittle -- keep some locales from messing up busybox.sh
15 * Matt Kraai -- cleaned up dd and tail with new parse_number routine
16 * Mark Whitley -- remove debugging messages from deallocvt
17 * Matt Kraai and Mark Whitley -- new document "How to Add a New Applet
19 * David Douthitt -- fixed "grep -qv" bug
20 * Larry Doolittle -- fixed insmod bug with old kernels
21 * Matt Kraai -- logger remixed to use getopt, selection of stdin made
23 * Erik Andersen -- many more internal symbols classified static to
24 avoid namespace pollution
25 * Matt Kraai -- nc listening support
26 * Erik Andersen -- made sed understand arbitrary regexp delimiters
27 * Matt Kraai et al. -- more tar improvements and bug fixes, now
28 handles regexp file exclusion
29 * Larry Doolittle -- new script (multibuild.pl) to automate build rule
31 * Matt Kraai -- update/cleanup of the docs on how to use init
32 * Erik Andersen -- renamed all sh.c symbols per the style guide,
33 better if-then-else-fi handling
34 * Erik Andersen -- cleaner division of labor between cmdedit.c and sh.c
35 * Larry Doolittle -- shell data structure cleanup, fixed buglets
36 in read, exec, and piped builtins
37 * Erik Andersen -- md5sum was broken in 0.48. Now fixed (and doesn't
38 use getline, shrinking static compiles (since nothing else used it).
39 * ?? -- squashed memory leak in shell prompt handling
40 * Mark Whitley -- Updates to style guide
41 * Mark Whitley -- Big cleanup in utility.c: style guide compliance,
42 de-macro-ifying some variables and functions
43 * Erik Andersen -- ls now honors BB_FEATURE_AUTOWIDTH so it can find
44 the width and height of the console.
45 * Erik Andersen -- insmod now ignores -L and accepts the -o option.
46 * Erik Andersen -- updates so you can now select from the Makefile
47 whether or not to use the system's passwd and group functions.
48 Since most systems use GNU libc, this can save you from having to
49 install the /etc/nsswitch.conf configuration file and the required
50 libnss_* libraries. Adds 1.5k. You can now, also, disable this,
51 causing busybox to use the system's pwd.h and grp.h functions.
54 -Erik Andersen, 27 January 2001
58 * Glenn McGrath -- tar now supports uncompressing tar files,
59 define BB_FEATURE_TAR_GZIP to use the -z option.
60 * Matt Kraai -- fix all usage of TRUE and FALSE so all apps now
61 return EXIT_SUCCESS or EXIT_FAILURE to the system.
62 Now TRUE and FALSE are set to the C standard where TRUE=1.
63 * me -- Fixed uname problem causing the kernel version to be
64 mis-detected (causing problems with poweroff, init,
66 * Alcove, Julien Gaulmin <julien.gaulmin@alcove.fr> and
67 Nicolas Ferre <nicolas.ferre@alcove.fr> -- insmod support on ARM
68 and StrongArm, and suport for lsmod on older 2.0.x kernels.
69 * Kent Robotti -- Renamed unrpm to original rpmunpack, so you can use
70 an included shell script called unrpm as a front end to it. There's
71 also a shell script called undeb included for debian packages.
72 * Matt Kraai -- fix an infinite loop with ls -aR
73 * Larry Doolittle -- Shaved off about 100 bytes and 200 bytes heap
74 from date.c. Also document the "-d" option in the usage message.
75 * Gennady Feldman -- fixed dd to use blocksize when reading/writing,
76 (it was reading the whole thing and then writing it out). Also
77 updated usage information (was missing conv=notrunc) and added
79 * Larry Doolittle (in collaboration with Matt Kraai) -- allow for a
80 pristine source directory -- where all the .o files and such are
81 not placed into the source tree. Thanks Larry!
82 * Larry Doolittle -- use the applet definitions in applets.h
83 to autogenerate the applet function and usage prototypes.
84 * Sebastien Huet, Arne Bernin, and Kent Robotti -- Add in tar -X and
85 fixed a bug breaking tar --exclude.
86 * Jonas Holmberg -- echo option handling made GNU-echo compatible
87 * Aleksey Demidov <asd@ixcelerator.com> -- date option handling made
89 * me -- Progress meter (optional) in wget
90 * Doolittle/me -- programs invoked by full path name take
91 precedence over applets unless BB_FEATURE_SH_BUILTINS_ALWAYS_WIN
92 * Gaute B Strokkenes <gs234@cam.ac.uk> -- applets found using a
93 binary search instead of linear search. Much faster!
94 * new applets: cmp readlink
95 * Mark Whitley -- Removed advertising clause of Berkeley license
96 according to decision by the Regents of the University of
97 California; included reference
98 * tail's confusing special treatment of single digit options removed;
99 people should use -n instead
100 * Larry Doolittle -- \r handled now in echo and tr
101 * Matt Kraai -- rewrite of uniq
102 * Mark Whitley -- remix of xargs
103 * Jim Gleason <jimg@lineo.com> -- fixed tar so it no longer breaks
105 * Matt Kraai -- logger now logs all arguments, not just the first
106 * Gennady Feldman -- syslogd no longer logs to localhost if compiled
107 for remote logging...
108 * Richard June <rjune@ims1.imagestream-is.com> -- support for 'gzip -d'
109 * various artists -- Other good stuff that I forgot to document.
112 -Erik Andersen, 13 December 2000
116 * A bug in syslogd was fixed that allowed it to potentially fork-bomb
117 your system. Anyone using 0.46 syslogd should upgrade.
118 * Renamed busybox.defs.h to the more sensible "Config.h"
119 * Improved portability between different libcs.
120 * Many apps ported to use getopt()
121 * Common handling of '--help'
122 * All usage messages centralized.
123 * Added a bunch of new commands:
124 * 'rdate' contributed by Sterling Huxley <sterling@europa.com>
125 * 'wget' contributed by Chip Rosenthal <chip@unicom.com>,
126 <crosenth@covad.com> and Covad Communications
127 * 'getopt' from "Alfred M. Szmidt" <ams@trillian.itslinux.org>
128 * dos2unix, unix2dos, reset, and unrpm.c (and lots of help
129 debugging) thanks to Kent Robotti <robotti@metconnect.com>.
130 * 'renice' command, thanks to Dave Cinege <dcinege@psychosis.com>
131 * 'xargs' (written by me)
132 * 'expr' contributed by Edward Betts <edward@debian.org>, based
134 * lsmod now uses the query_module syscall, rather then /proc (me)
135 * syslogd can now log messages to remote hosts -- patch thanks
136 to Gyepi Sam <gyepi@praxis-sw.com>
137 * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>
138 * 'make install' now creates relative symlinks, and added a new
139 'make install-hardlinks' target to (tada) install hardlinks.
140 * Rewrite of 'tail' to make it simpler, smaller, and more robust.
141 It now weighs only 2.25k (3k when full featured). The code is
142 cleaner too, thanks to Allen Soard <esp-software@mail.hypermart.net>
143 * Add optional ls file sorting, thanks to a patch from
144 Sterling Huxley <sterling@europa.com>
145 * Fixed chmod option parsing so things like 'chmod -r /tmp/file'
146 now work (previously it thought -r was an option). Doh!
147 * Fixed tar handling of stdin and stdout
148 * Renamed "internal.h" to the more sensible "busybox.h"
149 * Preliminary support for GNU HURD.
150 * Updated my devps and devmtab kernel patches for the latest 2.2.x
151 kernel, for those wanting to go proc-less.
152 * Tons of other bugfixes.
155 -Erik Andersen, 25 September 2000
160 * Better portability. Now should compile cleanly with libc5,
161 GNU libc 2.0 and 2.1, and various Linux kernels including
162 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
163 to make /proc/mounts behave included in the kernel-patches dir).
164 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
165 local files that matched tarball contents!!! Fix thanks
166 to Marius Groeger <mgroeger@sysgo.de>
167 * Fixed a nasty bug in tar when could mess up saved symlinks.
168 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
169 thanks to Daniel Quinlan <quinlan@transmeta.com>
170 * Updates to handle Linux 2.4.0 kernels (kludged around the
171 "none" entries in /proc/mounts, added a hack to make sysinfo
172 work with both old and new kernels).
173 * Fixed insmod module option parsing for options lacking an '='.
174 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
175 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
176 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
177 * Several fixes from Marius Groeger <mag@sysgo.de>
178 - Added support for "sh -c command args..."
179 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
180 - Added shell environment variable substitution
181 - Added the "read" shell builtin.
182 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
183 used to create an infinite loop: ls, cursor up, left, down.
184 * Added support for being a login shell, so things like
185 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
186 invoke the shell. Now you can use BusyBox as a login shell.
187 * ls.c now ignores '-g', since some ftp clients like that sort
188 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
189 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
190 it always sets the controlling terminal before running any programs
191 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
192 - Fixed tr so it recognizes standard escape sequences.
193 Merged common escape seq. code from tr and echo into utility.c.
194 - Major work in updating/cleaning up the docs, and getting the
195 new SGML based docs into shape.
197 - BusyBox should now poweroff when asked to do so.
198 - Fixed 'ln -n' and 'ln -s' so they both work properly.
199 * Reorganized signal names in kill.c for better architecture support
200 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
201 * In 0.43, backspace and delete worked properly, but with 0.45,
202 it just echoed a ^? for backspace, and ^H for control-h. This
203 was due to a broken macro in init.c, that is now fixed.
204 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
205 couldn't maintain it very well, so including it was not really
206 very appropriate. Those wanting an fdisk are invited to
207 grab a copy from util-linux.
208 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
209 then be loaded in by 'loadkmap' -- submitted by
210 Arne Bernin <arne@matrix.loopback.org>
211 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
212 * Brand, new versions of grep and sed which use libc regex routines,
213 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
214 "regexp.[ch]" files have been removed. Much help on these from
218 -Erik Andersen, 11 July 2000
222 * Now compiles vs libc5 (which can save lots of space for
224 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
225 help messages (i.e --help). Saves 17k over a full compile.
226 * Added cut and tr from minix, since due to the license change,
227 we can now use minix code. Minix tr saves 4k.
228 * insmod now works. It costs 29k, but imagine an initrd with a
229 staticly linked busybox containing only insmod and sh, a few /dev
230 entries, and a kernel module or two... It doesn't get smaller
231 then this folks (I pity the fool that writes insmod in asm ;-).
232 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
233 * Added a mini ar archive utility, especially written for BusyBox by
234 Glenn McGrath <bug1@netconnect.com.au>
235 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
236 * Added setkeycodes, for those that have wierd keyboard buttons.
237 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
238 <ams@trillian.itslinux.org> for contributing these.
239 * Added 'grep -v' option (inverted search) and updated
240 docs accordingly. -beppu
242 * Replaced the telnet implementation with one written by
243 Tomi Ollila <too@iki.fi> It works great and costs 3k.
244 * BusyBox sh (lash) now supports being used as a standalone shell. When
245 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
246 be invoked as shell internals. Best used when compiling staticly
248 * BusyBox sh (lash) internals now behave as expected wrt pipes
250 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
251 * Fixed update segfault
252 * Fixed mknod -- minor number was always 0
253 * Fixed tar option parsing, so both "tar xvf foo.tar" and
254 "tar -xvf foo.tar" now work (i.e. no "-" before options)
255 (this was very broken in 0.43).
256 * Several contributions from Randolph Chung <tausq@debian.org>.
257 * cp/mv now accepts the -f flag
258 * tail can now accept -<num> commands (e.g. -10) for better
259 compatibility with the standard tail command
260 * added a simple id implementation; doesn't support sup. groups yet
261 * logname used getlogin(3) which uses utmp. Now it doesn't.
262 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
263 * Add support for "noatime" and "nodiratime" mount flags to mount.
264 * Changed 'umount -f' to mean force, and actually use umount2.
265 * Changed 'umount -l' to mean "Do not free loop device".
266 * Fixed basename to support stripping of suffixes. Patch thanks
267 to xiong jianxin <jxiong@uiuc.edu>
268 * cp -fa now works as expected for symlinks (it didn't before)
269 * zcat now works (wasn't working since option parsing was broken)
270 * Renamed "mnc" to the more correct "nc" (for netcat).
271 * Makefile intelligence updates
272 * Changed the way init parses /etc/inittab entries to avoid problems
273 with commands that contain colons in them. Fix thanks to
274 Pavel Roskin <proski@gnu.org>
275 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
276 Fix thanks to Pavel Roskin <proski@gnu.org>
277 * Made "killall" complain (not error and exit) about processes that it
278 cannot find by name -- Pavel Roskin <proski@gnu.org>
279 * Fixed more and ps to have sensible terminal width defaults, thanks
281 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
282 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
283 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
284 * Fixed segfault caused by "touch -c"
285 * Fixed segfault caused by "rm -f"
286 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
287 and "--" support from Pavel Roskin.
288 * Fixed segfault caused by "cp -a -a" and similar abuses.
289 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
290 * "which" rewritten to use stat(). Fixes to improve its compatability
291 with traditional implementations -- Pavel Roskin.
292 * "mount" now reports errors from nfsmount() and assumes NFS mount
293 if ':' is present in the device name - Pavel Roskin
294 * Fixed exit status for killall - Pavel Roskin
295 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
296 * Fixed 'mount -a' so it works as expected.
297 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
298 * Implemented "ping -s", fixed error messages and argument parsing -
300 * Syslogd will not go to background if "-n" is given. Better help
301 and argument checking -- Pavel Roskin
302 * Fixed a small bug that could cause tar to emit warning messages
303 and not extract the first file in a directory in some cases
304 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
305 for helping track this one down.
307 * Fixed grep "Line too long" problem -- John Beppu
308 * Fixed 'grep -q -i B some_file' so it works
309 * math takes input from stdin if no args are given. -- John Beppu
310 * math was renamed to dc. Although it deviates from dc's behaviour,
311 this will probably be remedied in the future. -- John Beppu
314 -Erik Andersen, June 21, 2000
318 Previously, an erronous announcement of BusyBox 0.44 was made, so to
319 avoid possible confusion, we are skipping straight to 0.45, and calling
326 * Major update to the provided documentation.
327 * Busybox now includes a shell! It currently costs 7.5 k (plus an
328 additional 2.5 k if you compile in command line editing). Handles
329 job control, has the usual set of builtins, and does everything
330 except for handling programming statements (if, while, etc...)
331 * Busybox can now work perfectly when /proc is disabled, thereby
332 saving a bunch of memory (kernel /proc support is not thin). This
333 is done by making use of some nice kernel patches I wrote up to
334 support the features that busybox requires and that /proc usually
335 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
336 patch your kernel with the devps patch in the kernel-patches/
338 * Wrote basename, dirname, killall, and uptime.
339 * tar has been completely rewritten by me. Both tar creation and
340 extraction are now well behaved. Costs 7.6k with all optional
341 tar features enabled, and 5k for just tar extraction support.
342 * Added freeramdisk, which will free up all memory associated
343 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
344 and then adjusted a bit by me.
345 * Added tr from John Lombardo <john@deltanet.com>
346 * Added echo and test (from me).
347 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
348 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
349 * Several fixes from Pavel Roskin <proski@gnu.org>:
350 - When `tail' fails to open a file it now exits.
351 - When `syslogd' is given the `-n' option it should still use
352 fork() for running klogd.
353 * nslookup types are now changed to u_int32_t (instead of uint32_t)
354 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
355 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
356 to count hard-linked files more then once). Many thanks to
357 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
358 * Removed /proc dependancies for init and free (while maintaining
359 exactly the same functionality). /proc takes up 90k of kernel
360 space, so it is nice to avoid using it at all costs.
361 * init no longer tries to mount /proc (unless there is less the 1 meg
362 free). Use of /proc (or not) is policy that should be set up in
363 /etc/fstab (or in hardcoded scripts), not in init.
364 * Fixed rebooting when init runs as an initrd.
365 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
366 - update.c rewritten to look more like update-2.11
367 - moveed the inode hash out of du.c and into utility.c to make
368 it a common resource that can be used by other apps.
369 - cp_mv.c now checks inodes to see if a source and dest are
370 the same, and prints an error (instead of endlessly looping).
371 - mv now attempts to do a rename, and will fall back to doing
372 a copy only if the rename fails.
373 - Syslogd now supports multiple concurrent connections
374 * Several fixes from Pavel Roskin <proski@gnu.org>:
375 - Fixes to sort. Removed "-g", fixed and added "-r"
376 - Fixes to the makefile for handling "strip"
377 * An initial telnet implementation was added by
378 Randolph Chung <tausq@debian.org>.
379 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
380 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
381 to match the terminal (defaults to width=79 when this is off).
382 * ps now accepts (and ignores) all options except for "--help" (which
383 as would be expected displays help).
384 * Fixed mount'ing loop devices when the filesystem type was not
385 specified. It used to revert to non-loop after the first try.
386 * all mallocs now use xmalloc (and so are OOM error safe), and
387 the common error handling saves a few bytes. Thanks to
388 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
389 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
390 * Fix symlink following bug in chmod -R and friends.
391 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
392 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
401 * Fairly massive restructuring of umount.c to deal with remounting
402 busy devices read-only. Adds a -r option to control that; it is
403 optionally compiled in with BB_FEATURE_REMOUNT
404 * Added a bunch of functions to mtab.c to interact with the
405 {get,set,end}mntent interface; as it turns out, those functions do
406 not appear to be re-entrant, and that causes a lot of problems with
407 the way umount was originally written.
408 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
409 to be more consistent with sysvinit
410 * Changes to init.c to use the new -r option to umount. Also increased
411 the sleep time between the time the TERM and KILL signals are sent
416 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
417 extensively rewritten from the original cp.c.
418 * Fixed cp and mv so if the source and destination are a the
419 same directory it will print an error and continue.
420 * Also added a warning message to the `mv' usage string saying that
421 this is not GNU mv, and it will break hard links. cp also breaks
423 * ln.c: implemented `-n' switch, no-deref symlinks.
424 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
425 * name buffer overrun guards to prevent future crashes.
426 - Always check exit status.
427 - Purge all use of `creat()', replace with `open()'.
429 - recursiveAction was overriding the value of followLinks thus
431 - isDirectory now takes a followLinks boolean, updated all callers
432 - copyFile had the followLinks logic reversed.
433 * messages.c: New file. Put common error message strings all in
434 one place in an attempt to shrink the binary a little.
439 * changed fsck_minix.c to reduce its .bss size significantly
441 * Made tar creation support in busybox tar optional. You no longer
442 * _have_ to put a "-" in front of tar options. Tar could inadvertently
443 * change permissions and ownership on
444 certain directories pointed to by symlinks.
445 * Made grep and grep -h do the right thing wrt printing
446 the file name (it failed to print files names in many cases).
447 * Fix a namespace aliasing problem wereby if du was built in, the
448 symlink for both du and dutmp would be installed, or then rm was
449 built in, the symlinks for both rm and rmmod would be installed.
450 * Added a closelog() to init.c after loging -- fix thanks to
451 Taketoshi Sano <kgh12351@nifty.ne.jp>
452 * Rewrote and simplified logger. Added the "-t" option, and made it
453 behave itself a bit better.
454 * Optional support contributed by Ben Collins <bcollins@debian.org>
455 for the kernel init chroot patch by Werner Almesberger, which
456 allows init to chroot to a new device, and umount the old one.
457 * Fixed bug that wouldn't let one chown a symlink -- it would
458 always dereference before. -beppu
459 * Fixed a bug where init could have reference already freed memory.
460 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
461 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
462 * Added (and documented) "-n" option for head
463 * Cleanup for a number of usage messages -- also
464 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
465 * Cosmetic fix to busybox.c (Don't print a comma at the
466 end of line if there are no more application names).
467 * Fixed a stupid bug in "head" option handling ("head -n"
469 * Moved commonly used functions "xmalloc()" and "exit()"
470 to utility.c (with proper #ifdef's).
471 * Created a tiny tail implementation, removing -c, -q, -v, and making
472 tail -f work only with a single file. This reduced tail from 6k to
473 2.4k. The bigger/more featured tail can still be had by disabling
474 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
475 * Ping now falls back to doing the right thing if /etc/protocols
477 * Fixed mount and umount. Previously they could leak loop device
478 allocations, causing the system to quickly run out. Fix for umount
479 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
480 * ls formatting on eight charactor user names fixed by
481 Randolph Chung <tausq@debian.org>.
482 * cp could, when copying symlinks, change permissions of the
483 files pointed to by the symlinks.
484 * Several fixes from Pavel Roskin <proski@gnu.org>:
485 - `chown' with 1 argument displayed the error incorrectly
486 - `fdflush', `length' and `printf' crashed if run without arguments
487 - `fdflush' tried to flush itself using *argv
488 - added "skip" and "seek" to dd.
489 - ls no longer messus up output when combining files and
490 directories on the command line
491 * swapoff -a was not working. Now it is.
492 * init did not cleanly unmount filesystems on reboot. Now it does.
493 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
495 * Some architectures (PowerPc) assume chars are unsigned, so they could
496 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
497 * Began converting error handling to use some common routines
499 * syslogd now has better message handling and ignores SIGHUP.
500 * install.sh had a bug preventing installation to the specified
501 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
502 * You can now spefify alternative strip commands -- change
503 also from Gilbert Coville.
509 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
510 by Edward Betts <edward@debian.org>
511 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
512 type commands (file in a directory to another directory) from
514 * Fixed a logger bug that caused garbage to be written to the syslog
515 (unless you used busybox syslog, which hid the bug). Thanks to
516 Alex Holden <alex@linuxhacker.org> for the fix.
517 * /bin/true and /bin/false were echoing a blank line when run.
519 * mkdir -p would print an error when asked to mkdir an existing dir
520 with no interveining subdirectories.
521 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
522 * and support in umount for loop
523 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
524 <bcollins@debian.org>
525 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
526 * fullWrite() not only if BB_TAR is defined, but also
527 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
528 * add some compiler optimizations to further reduce executable size
529 (as a side note, on my machines the largest code is generated
530 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
532 * Compile now won't fail if busybox.def.h defines
533 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
534 referenced, but not compiled)
535 * Fixed a bug in setting TERM for serial console support. TERM now
536 defaults to "ansi" for serial consoles.
537 * Fixed a bug in handling the CONSOLE env. variable for serial
540 -Erik Andersen, Jan 15, 2000
543 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
544 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
545 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
546 for loading application character maps for Unicode fonts.
547 * Major init re-work. init now supports inittab (slightly different
548 but similar to sysvinit), allowing me to get all the policy out of
549 init and into the conf file. It works just fine without inittab
550 being present, but if you dont like the default behavior you can
551 now do something about it. Init is much cleaner as a result.
552 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
553 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
554 * failure of 'logger -p'. -erik Added the -s option to du -beppu
555 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
556 with the 2.0.x Linux kernel.
557 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
559 * Grep -i previously failed on UPPER CASE patterns due to a silly
560 regexp implementation bug that is now fixed.
561 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
562 * Fixed a bug where tar would not set the user and group on device
564 * Fixed a bug where tar would not restore the time to files. Fixed a
565 * major security problem with tar -- it changed ownership
566 of any file pointed to by a symlink to 777 (like say libc....)
568 * cp and mv were very broken when moving directories. I have rewritten
569 them so they should now work as expected.
570 * sed now supports addresses (numeric or regexp, with negation) and
571 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
572 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
573 * Some cosmetic fixes to ls output formatting to make it behave more
575 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
576 * <fwv@myrtle.lahn.de>:
577 - Added gunzip -t, removed gunzip.c dead code,
578 - fixed several typos
579 - Glibc 2.0.7 and libc5 compile fixes
580 * Fixed a bug where 'mknod --help' would segfault.
583 -Erik Andersen, Jan 07, 2000
586 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
587 <tausq@debian.org>. 3 items off the TODO list!
588 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
589 * tail from GNU textutils-1.19, but adjusted
590 to suit my evil purposes. Costs 6k. I'll make it smaller
592 * on reboot, init called 'umount -a -n', which caused errors
593 when BB_MTAB was not enabled. Changed to 'umount -a', which does
595 * init will now try to run /sbin/getty if it is present (for easy
596 integration with the about-to-be-released tinylogin.)
597 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
598 * -l' was failing on long directories, since my_getid was leaking
599 one file descriptor per file. Oops.
600 * Fixed rebooting from init. I'd accidently left some debugging code
602 which blocked reboots.
603 * Fixed reboot, halt (and added poweroff) such that they handle it when
604 init is not at PID 1 (like when running in an initrd).
605 * Added a prelinary du implementation. Some parameter parsing
606 stuff still needs to be added. -beppu (John Beppu
608 * Implemented tee. -beppu Implemented head. -beppu
610 -Erik Andersen, Dec 10, 1999
613 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
615 * df will not exit on error, but will stat all mounted filesystems.
616 * Fixed tar so uid/gid/permissions on extracted tarballs will be
618 * Fixed find -name so it properly uses shell wildcard patterns
619 (i.e. `*', `?', and `[]') instead of regular expressions, which
620 was causing some confusing and unexpected behavior.
621 * Added klogd to syslogd, so now the log will contain both system and
623 * syslogd now creates the /dev/log socket to make sure it is there, and
624 is actually a socket with the right permissions.
625 * I've taken a first step to making busybox not need the /proc
626 filesystem. Most apps don't need it. Those that _require_ it,
627 will complain if you enable them when you disable
628 BB_FEATURE_USE_PROCFS.
630 -Erik Andersen, Dec 5, 1999
633 * Wrote a micro syslogd, and a logger util (to log things to the syslog
634 from the command line or scripts) With both compiled in, costs 4k.
635 * Fixed 'make install' so symlinks are installed in their proper
636 * locations. Changed the build system slightly so that features can
638 or disabled from the busybox.defs.h header file, without trying to
639 compile in a source file named after that featue (unless that file
641 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
642 * -r' both work. dd now properly handles input beyond 1 block from
643 * stdin. Fixed a bug where tar unpacked everything a directories.
645 from createPath into mkdir where it belonged, thereby making tar
647 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
649 last file in the list.
650 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
652 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
653 are presented properly.
657 -Erik Andersen, Nov 25, 1999
660 * fixed dd so it properly defaults to stdin and stdout when no
661 if= and of= are set (fix thanks to Eric Delaunay).
662 * Don't try to close the file descriptor of a pipein tar. (fix also
665 * Made createPath be quiet (again thanks to Eric Delaunay). If
666 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
667 command you define it as will be run if the init script exits.
668 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
669 * NFS support added to mount by Eric Delaunay. It costs 10k when
671 in, but that is still a big win for those that use NFS.
672 * Made 'rm -f' be silent for non-existant files (thanks to Eric
673 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
675 and acts as god intended gunzip and zcat to act. They answer
676 --help and obey the '-c' flag.
677 * Fixed a bug in mv which caused it to not move files when the
680 * Fixed a decimal-instead-of-octal bug causing mkdir to make
682 with very wrong permissions.
683 * chmod would overwrite file permissions instead of modifying them.
684 Now it properly modifies permissions.
685 * Init now sends warnings destined for the console to /dev/console to
687 they show up on whatever the active console it. Otherwise
688 important messages (for example that the system is rebooting) were
689 not seen when switched to a different VT.
691 -Erik Andersen, Nov 17, 1999
694 * gzip now obeys the principle of least surprise and acts like god
696 (i.e. it accepts a file name, answers --help, and obeys the '-c'
697 flag and only then outputs to stdout).
698 * Fixed more.c to compile autowidth on sparc and set initial winsize
699 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
701 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
702 * tar now accepts --help chmod, chown, and chgrp usage now works
703 * General usage (i.e. --help) cleanups for most apps umount now parses
704 * options correctly tar can now unpack tarballs containing device
706 sockets, and fifos (though it can't pack them up) thanks to Matt
707 Porter. Creating archives containing these is still left to the
709 * fixed up the license in more.c to properly point to Bruce Perens.
711 -Erik Andersen, Nov 11, 1999
714 * ls -l now displays link names outside the current directory,
715 Patch thanks to Eric Delaunay
716 * init now properly handles sparc serial consoles and does a
717 better job of finding the real console device rather than using
718 /dev/console which doesn't support job control. Patch also thanks
720 * more started to read from stdin after the last file was finished, and
721 options were not parsed correctly (fix thanks to Eric Delaunay).
722 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
723 * rm wouldn't remove a symlink unless the symlink was valid. This was
724 a side effect of the busybox 0.32 recursiveAction() fix. Things
725 should now work correctly.
726 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
727 * it does. sed was appending a \n to the end of lines with
729 Now it doesn't do that.
730 * ls -l now bypasses libc6 nss when displaying user/group names.
731 Now uses my_getpwuid and my_getgrgid.
733 -Erik Andersen, Nov 8, 1999
736 * Fixed a bug where init could hang instead of rebooting.
737 * Removed some debugging noise from init.c
738 * Fixed ln so it works now (it was very broken).
739 * Fixed df so it won't segfault when there is no /etc/fstab,
740 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
741 is not installed (since they cannot fixup "/dev/root" to
742 state the real root device name)
743 * merged some redundant code from mtab.c/df.c into utility.c
745 -Erik Andersen, Nov 5, 1999
748 * More changes -- many thanks to Lineo for paying me to work on
749 busybox. If you have any problems please let me know ASAP at
750 andersen@lineo.com or andersee@debian.org
751 * usage() now prints the BusyBox version. This will help folks
752 realize that they are not in Kansas anymore.
753 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
754 * arguments. Now it doesn't do that. kill wasn't properly accepting
755 * signal names. It does now. Added new apps chvt and deallocvt (I
756 * should probably add open) Major rewrite of init.c. Code is now
757 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
758 * with full regular expressions!). Fixed a stupid seg-fault in sync
759 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
760 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
761 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
762 * cost of ~1.5k and the need for a rw /etc)
763 folks to use a real /etc/mtab file instead of a symlink to
764 /proc/mounts. mount, and umount will add/remove entries and df
765 will now use /etc/mtab if BB_MTAB is defined.
766 * Fixed a nice bug in recursiveAction() which caused it to infinitely
767 hunt through /proc/../fd/* creating new file descriptors if it
768 followed the /dev/fd link over to /proc. recursiveAction() now
769 lstat's the file when followLinks==FALSE so it won't follow links
770 as the name suggests. Fix thanks to Matt Porter
774 -Erik Andersen, Nov 4, 1999
777 * I added a changelog for version 0.30. adjusted find internals to
778 * make it smaller, and removed
780 * Fixed a segfault in ps when /etc/passwd or /etc/group
781 are absent. Now will warn you and carry on.
782 * Added in optional _real_ regular expression support (to be
783 the basis for a future sed utility). When compiled in it adds
784 3.9k, but makes grep much more capable.
785 * Checked out using nftw(3) for recursive stuff, but unfortunatly
786 it wasn't supported before GNU libc 2.1, and some folks use glibc
787 2.0.7 since it is much smaller than that latest and greatest.
789 -Erik Andersen, Oct 21, 1999
792 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
793 paying me to make these updates. If you have any problems with busybox,
794 or notice any bugs -- please let me know so I can fix it. These
798 * busybox can now invoke apps in two ways: via symlinks to the
799 busybox binary, and as 'busybox [function] [arguments]...'
800 * When invoked as busybox, the list of currently compiled in
801 functions is printed out (no this is not bloat -- the list has
802 to be there anyway to map invocation name to function).
803 * busybox no longer parses command lines for apps or displays their
804 usage info. Each app gets to handle (or not handle) this for
806 * Eliminated monadic, dyadic, descend, block_device, and
807 postprocess. It was cumbersome to have so many programs
808 cobbled together in this way. Without them, the app is much
810 * All shared code now lives in utility.c, and is properly
811 ifdef'ed to be only included for those apps requiring it.
812 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
813 so now each app has the function prototype of (da-dum): extern
814 int foo_main(int argc, char** argv); which speeds integration
816 * Adjusted the Makefile to make it easier to
817 {en|dis}able debugging.
818 * Changed default compiler optimization to -Os
819 (optimize for smaller binaries).
822 * To cope with the new app function prototype and the removal of
823 monadic, dyadic, etc, the following apps were re-written:
824 * cat - Works same as always. chgrp, chmod, chown -
825 * rewrite. Combined into a single
826 source file. Absorbed patches from Enrique Zanardi
827 <ezanard@debian.org> that removes the dependency on
828 libc6 libnss* libraries.
829 * cp - Can now do 'cp -a' can can copy devices,
830 pipes, symlinks, as well as recursive or non-recursive
832 * fdflush - adjusted to remove dependancy on struct
833 * FileInfo. find - Now includes some basic regexp matching
834 which will be the basic of a future mini-sed.
835 * ln - Same functionality. mkdir - Added -p flag to
836 * feature set. mv - rewrite. rm - Added -f flag to
837 * feature set. rmdir - Same functionality. swapon,
838 * swapoff - Combined into a single binary. No longer
839 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
841 * touch - Same functionality. date - adjusted with a patch
842 * from Matthew Grant <grantma@anathoth.gen.nz>
843 to accomodate glibc timezone support. I then ripped out GNU
845 * mkswap -- new version merged from util-linux. Can now make
847 * Replaced the old and star, unstar, and tarcat with the tar
848 implementation from sash. Now tar behaves as god intended it
849 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
850 * dd -- rewritten. Can with with files, stdin, stdout. Added the
851 * following new apps: loadfont -- added from debian boot floppies
852 * chroot -- added based on a patch from Paolo Molaro
853 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
854 * simple strings ps -- I just wrote it. Has _no_ options at all,
855 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
857 internationalization and such to make them smaller.
858 * sfdisk -- Added from util-linux (minus
859 * internationalization and such). Probably some other
860 * changes that I forgot to document...
862 -Erik Andersen, Oct 20, 1999
865 This version was a messy pre-alpha. stay away or it will bite you.
866 -Erik Andersen, Sep 24, 1999
869 mini-netcat (mnc) rewritten.
872 Mount now supports -a, and -t auto.
873 Mount now updates mtab correctly for 'ro'.
874 More checks screen rows size, outputs bytes percentage.
875 Printf added as module.
877 Touch now creates files. -c option for no create.
