3 * Glenn McGrath -- tar now supports uncompressing tar files,
4 define BB_FEATURE_TAR_GZIP to use the -z option.
5 * Matt Kraai -- fix all usage of TRUE and FALSE so all apps now
6 return EXIT_SUCCESS or EXIT_FAILURE to the system.
7 Now TRUE and FALSE are set to the C standard where TRUE=1.
8 * me -- Fixed uname problem causing the kernel version to be
9 mis-detected (causing problems with poweroff, init,
11 * Alcove, Julien Gaulmin <julien.gaulmin@alcove.fr> and
12 Nicolas Ferre <nicolas.ferre@alcove.fr> -- insmod support on ARM
13 and StrongArm, and suport for lsmod on older 2.0.x kernels.
14 * Kent Robotti -- Renamed unrpm to original rpmunpack, so you can use
15 an included shell script called unrpm as a front end to it. There's
16 also a shell script called undeb included for debian packages.
17 * Matt Kraai -- fix an infinite loop with ls -aR
18 * Larry Doolittle -- Shaves off about 100 bytes and 200 bytes heap
19 from date.c. Also document the "-d" option in the usage message.
20 * Gennady Feldman -- fixed dd to use blocksize when reading/writing,
21 (it was reading the whole thing and then writing it out). Also
22 updated usage information (was missing conv=notrunc) and added
24 * Larry Doolittle (in collaboration with Matt Kraai) -- allow for a
25 pristine source directory -- where all the .o files and such are
26 not placed into the source tree. Thanks Larry!
27 * Larry Doolittle -- use the applet definitions in applets.h
28 to autogenerate the applet function and usage prototypes.
29 * Sebastien Huet, Arne Bernin, and Kent Robotti -- Add in tar -X and
30 fixed a bug breaking tar --exclude.
31 * Jonas Holmberg -- echo option handling made GNU-echo compatible
32 * Aleksey Demidov <asd@ixcelerator.com> -- date option handling made
34 * me -- Progress meter (optional) in wget
35 * Doolittle/me -- programs invoked by full path name take
36 precedence over applets unless
37 BB_FEATURE_SH_BUILTINS_ALWAYS_WIN
38 * Gaute B Strokkenes <gs234@cam.ac.uk> -- applets found using a
39 binary search instead of linear search. Much faster!
40 * new applets: cmp readlink
41 * Mark Whitley -- Removed advertising clause of Berkeley license
42 according to decision by the Regents of the University of
43 California; included reference
44 * tail's confusing special treatment of single digit options removed;
45 people should use -n instead
46 * Larry Doolittle -- \r handled now in echo and tr
47 * Matt Kraai -- rewrite of uniq
48 * Mark Whitley -- remix of xargs
49 * Jim Gleason <jimg@lineo.com> -- fixed tar so it no longer breaks
51 * Matt Kraai -- logger now logs all arguments, not just the first
52 * Gennady Feldman -- syslogd no longer logs to localhost if compiled
60 * A bug in syslogd was fixed that allowed it to potentially fork-bomb
61 your system. Anyone using 0.46 syslogd should upgrade.
62 * Renamed busybox.defs.h to the more sensible "Config.h"
63 * Improved portability between different libcs.
64 * Many apps ported to use getopt()
65 * Common handling of '--help'
66 * All usage messages centralized.
67 * Added a bunch of new commands:
68 * 'rdate' contributed by Sterling Huxley <sterling@europa.com>
69 * 'wget' contributed by Chip Rosenthal <chip@unicom.com>,
70 <crosenth@covad.com> and Covad Communications
71 * 'getopt' from "Alfred M. Szmidt" <ams@trillian.itslinux.org>
72 * dos2unix, unix2dos, reset, and unrpm.c (and lots of help
73 debugging) thanks to Kent Robotti <robotti@metconnect.com>.
74 * 'renice' command, thanks to Dave Cinege <dcinege@psychosis.com>
75 * 'xargs' (written by me)
76 * 'expr' contributed by Edward Betts <edward@debian.org>, based
78 * lsmod now uses the query_module syscall, rather then /proc (me)
79 * syslogd can now log messages to remote hosts -- patch thanks
80 to Gyepi Sam <gyepi@praxis-sw.com>
81 * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>
82 * 'make install' now creates relative symlinks, and added a new
83 'make install-hardlinks' target to (tada) install hardlinks.
84 * Rewrite of 'tail' to make it simpler, smaller, and more robust.
85 It now weighs only 2.25k (3k when full featured). The code is
86 cleaner too, thanks to Allen Soard <esp-software@mail.hypermart.net>
87 * Add optional ls file sorting, thanks to a patch from
88 Sterling Huxley <sterling@europa.com>
89 * Fixed chmod option parsing so things like 'chmod -r /tmp/file'
90 now work (previously it thought -r was an option). Doh!
91 * Fixed tar handling of stdin and stdout
92 * Renamed "internal.h" to the more sensible "busybox.h"
93 * Preliminary support for GNU HURD.
94 * Updated my devps and devmtab kernel patches for the latest 2.2.x
95 kernel, for those wanting to go proc-less.
96 * Tons of other bugfixes.
99 -Erik Andersen, 25 September 2000
104 * Better portability. Now should compile cleanly with libc5,
105 GNU libc 2.0 and 2.1, and various Linux kernels including
106 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
107 to make /proc/mounts behave included in the kernel-patches dir).
108 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
109 local files that matched tarball contents!!! Fix thanks
110 to Marius Groeger <mgroeger@sysgo.de>
111 * Fixed a nasty bug in tar when could mess up saved symlinks.
112 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
113 thanks to Daniel Quinlan <quinlan@transmeta.com>
114 * Updates to handle Linux 2.4.0 kernels (kludged around the
115 "none" entries in /proc/mounts, added a hack to make sysinfo
116 work with both old and new kernels).
117 * Fixed insmod module option parsing for options lacking an '='.
118 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
119 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
120 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
121 * Several fixes from Marius Groeger <mag@sysgo.de>
122 - Added support for "sh -c command args..."
123 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
124 - Added shell environment variable substitution
125 - Added the "read" shell builtin.
126 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
127 used to create an infinite loop: ls, cursor up, left, down.
128 * Added support for being a login shell, so things like
129 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
130 invoke the shell. Now you can use BusyBox as a login shell.
131 * ls.c now ignores '-g', since some ftp clients like that sort
132 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
133 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
134 it always sets the controlling terminal before running any programs
135 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
136 - Fixed tr so it recognizes standard escape sequences.
137 Merged common escape seq. code from tr and echo into utility.c.
138 - Major work in updating/cleaning up the docs, and getting the
139 new SGML based docs into shape.
141 - BusyBox should now poweroff when asked to do so.
142 - Fixed 'ln -n' and 'ln -s' so they both work properly.
143 * Reorganized signal names in kill.c for better architecture support
144 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
145 * In 0.43, backspace and delete worked properly, but with 0.45,
146 it just echoed a ^? for backspace, and ^H for control-h. This
147 was due to a broken macro in init.c, that is now fixed.
148 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
149 couldn't maintain it very well, so including it was not really
150 very appropriate. Those wanting an fdisk are invited to
151 grab a copy from util-linux.
152 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
153 then be loaded in by 'loadkmap' -- submitted by
154 Arne Bernin <arne@matrix.loopback.org>
155 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
156 * Brand, new versions of grep and sed which use libc regex routines,
157 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
158 "regexp.[ch]" files have been removed. Much help on these from
162 -Erik Andersen, 11 July 2000
166 * Now compiles vs libc5 (which can save lots of space for
168 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
169 help messages (i.e --help). Saves 17k over a full compile.
170 * Added cut and tr from minix, since due to the license change,
171 we can now use minix code. Minix tr saves 4k.
172 * insmod now works. It costs 29k, but imagine an initrd with a
173 staticly linked busybox containing only insmod and sh, a few /dev
174 entries, and a kernel module or two... It doesn't get smaller
175 then this folks (I pity the fool that writes insmod in asm ;-).
176 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
177 * Added a mini ar archive utility, especially written for BusyBox by
178 Glenn McGrath <bug1@netconnect.com.au>
179 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
180 * Added setkeycodes, for those that have wierd keyboard buttons.
181 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
182 <ams@trillian.itslinux.org> for contributing these.
183 * Added 'grep -v' option (inverted search) and updated
184 docs accordingly. -beppu
186 * Replaced the telnet implementation with one written by
187 Tomi Ollila <too@iki.fi> It works great and costs 3k.
188 * BusyBox sh (lash) now supports being used as a standalone shell. When
189 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
190 be invoked as shell internals. Best used when compiling staticly
192 * BusyBox sh (lash) internals now behave as expected wrt pipes
194 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
195 * Fixed update segfault
196 * Fixed mknod -- minor number was always 0
197 * Fixed tar option parsing, so both "tar xvf foo.tar" and
198 "tar -xvf foo.tar" now work (i.e. no "-" before options)
199 (this was very broken in 0.43).
200 * Several contributions from Randolph Chung <tausq@debian.org>.
201 * cp/mv now accepts the -f flag
202 * tail can now accept -<num> commands (e.g. -10) for better
203 compatibility with the standard tail command
204 * added a simple id implementation; doesn't support sup. groups yet
205 * logname used getlogin(3) which uses utmp. Now it doesn't.
206 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
207 * Add support for "noatime" and "nodiratime" mount flags to mount.
208 * Changed 'umount -f' to mean force, and actually use umount2.
209 * Changed 'umount -l' to mean "Do not free loop device".
210 * Fixed basename to support stripping of suffixes. Patch thanks
211 to xiong jianxin <jxiong@uiuc.edu>
212 * cp -fa now works as expected for symlinks (it didn't before)
213 * zcat now works (wasn't working since option parsing was broken)
214 * Renamed "mnc" to the more correct "nc" (for netcat).
215 * Makefile intelligence updates
216 * Changed the way init parses /etc/inittab entries to avoid problems
217 with commands that contain colons in them. Fix thanks to
218 Pavel Roskin <proski@gnu.org>
219 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
220 Fix thanks to Pavel Roskin <proski@gnu.org>
221 * Made "killall" complain (not error and exit) about processes that it
222 cannot find by name -- Pavel Roskin <proski@gnu.org>
223 * Fixed more and ps to have sensible terminal width defaults, thanks
225 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
226 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
227 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
228 * Fixed segfault caused by "touch -c"
229 * Fixed segfault caused by "rm -f"
230 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
231 and "--" support from Pavel Roskin.
232 * Fixed segfault caused by "cp -a -a" and similar abuses.
233 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
234 * "which" rewritten to use stat(). Fixes to improve its compatability
235 with traditional implementations -- Pavel Roskin.
236 * "mount" now reports errors from nfsmount() and assumes NFS mount
237 if ':' is present in the device name - Pavel Roskin
238 * Fixed exit status for killall - Pavel Roskin
239 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
240 * Fixed 'mount -a' so it works as expected.
241 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
242 * Implemented "ping -s", fixed error messages and argument parsing -
244 * Syslogd will not go to background if "-n" is given. Better help
245 and argument checking -- Pavel Roskin
246 * Fixed a small bug that could cause tar to emit warning messages
247 and not extract the first file in a directory in some cases
248 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
249 for helping track this one down.
251 * Fixed grep "Line too long" problem -- John Beppu
252 * Fixed 'grep -q -i B some_file' so it works
253 * math takes input from stdin if no args are given. -- John Beppu
254 * math was renamed to dc. Although it deviates from dc's behaviour,
255 this will probably be remedied in the future. -- John Beppu
258 -Erik Andersen, June 21, 2000
262 Previously, an erronous announcement of BusyBox 0.44 was made, so to
263 avoid possible confusion, we are skipping straight to 0.45, and calling
270 * Major update to the provided documentation.
271 * Busybox now includes a shell! It currently costs 7.5 k (plus an
272 additional 2.5 k if you compile in command line editing). Handles
273 job control, has the usual set of builtins, and does everything
274 except for handling programming statements (if, while, etc...)
275 * Busybox can now work perfectly when /proc is disabled, thereby
276 saving a bunch of memory (kernel /proc support is not thin). This
277 is done by making use of some nice kernel patches I wrote up to
278 support the features that busybox requires and that /proc usually
279 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
280 patch your kernel with the devps patch in the kernel-patches/
282 * Wrote basename, dirname, killall, and uptime.
283 * tar has been completely rewritten by me. Both tar creation and
284 extraction are now well behaved. Costs 7.6k with all optional
285 tar features enabled, and 5k for just tar extraction support.
286 * Added freeramdisk, which will free up all memory associated
287 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
288 and then adjusted a bit by me.
289 * Added tr from John Lombardo <john@deltanet.com>
290 * Added echo and test (from me).
291 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
292 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
293 * Several fixes from Pavel Roskin <proski@gnu.org>:
294 - When `tail' fails to open a file it now exits.
295 - When `syslogd' is given the `-n' option it should still use
296 fork() for running klogd.
297 * nslookup types are now changed to u_int32_t (instead of uint32_t)
298 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
299 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
300 to count hard-linked files more then once). Many thanks to
301 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
302 * Removed /proc dependancies for init and free (while maintaining
303 exactly the same functionality). /proc takes up 90k of kernel
304 space, so it is nice to avoid using it at all costs.
305 * init no longer tries to mount /proc (unless there is less the 1 meg
306 free). Use of /proc (or not) is policy that should be set up in
307 /etc/fstab (or in hardcoded scripts), not in init.
308 * Fixed rebooting when init runs as an initrd.
309 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
310 - update.c rewritten to look more like update-2.11
311 - moveed the inode hash out of du.c and into utility.c to make
312 it a common resource that can be used by other apps.
313 - cp_mv.c now checks inodes to see if a source and dest are
314 the same, and prints an error (instead of endlessly looping).
315 - mv now attempts to do a rename, and will fall back to doing
316 a copy only if the rename fails.
317 - Syslogd now supports multiple concurrent connections
318 * Several fixes from Pavel Roskin <proski@gnu.org>:
319 - Fixes to sort. Removed "-g", fixed and added "-r"
320 - Fixes to the makefile for handling "strip"
321 * An initial telnet implementation was added by
322 Randolph Chung <tausq@debian.org>.
323 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
324 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
325 to match the terminal (defaults to width=79 when this is off).
326 * ps now accepts (and ignores) all options except for "--help" (which
327 as would be expected displays help).
328 * Fixed mount'ing loop devices when the filesystem type was not
329 specified. It used to revert to non-loop after the first try.
330 * all mallocs now use xmalloc (and so are OOM error safe), and
331 the common error handling saves a few bytes. Thanks to
332 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
333 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
334 * Fix symlink following bug in chmod -R and friends.
335 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
336 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
345 * Fairly massive restructuring of umount.c to deal with remounting
346 busy devices read-only. Adds a -r option to control that; it is
347 optionally compiled in with BB_FEATURE_REMOUNT
348 * Added a bunch of functions to mtab.c to interact with the
349 {get,set,end}mntent interface; as it turns out, those functions do
350 not appear to be re-entrant, and that causes a lot of problems with
351 the way umount was originally written.
352 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
353 to be more consistent with sysvinit
354 * Changes to init.c to use the new -r option to umount. Also increased
355 the sleep time between the time the TERM and KILL signals are sent
360 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
361 extensively rewritten from the original cp.c.
362 * Fixed cp and mv so if the source and destination are a the
363 same directory it will print an error and continue.
364 * Also added a warning message to the `mv' usage string saying that
365 this is not GNU mv, and it will break hard links. cp also breaks
367 * ln.c: implemented `-n' switch, no-deref symlinks.
368 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
369 * name buffer overrun guards to prevent future crashes.
370 - Always check exit status.
371 - Purge all use of `creat()', replace with `open()'.
373 - recursiveAction was overriding the value of followLinks thus
375 - isDirectory now takes a followLinks boolean, updated all callers
376 - copyFile had the followLinks logic reversed.
377 * messages.c: New file. Put common error message strings all in
378 one place in an attempt to shrink the binary a little.
383 * changed fsck_minix.c to reduce its .bss size significantly
385 * Made tar creation support in busybox tar optional. You no longer
386 * _have_ to put a "-" in front of tar options. Tar could inadvertently
387 * change permissions and ownership on
388 certain directories pointed to by symlinks.
389 * Made grep and grep -h do the right thing wrt printing
390 the file name (it failed to print files names in many cases).
391 * Fix a namespace aliasing problem wereby if du was built in, the
392 symlink for both du and dutmp would be installed, or then rm was
393 built in, the symlinks for both rm and rmmod would be installed.
394 * Added a closelog() to init.c after loging -- fix thanks to
395 Taketoshi Sano <kgh12351@nifty.ne.jp>
396 * Rewrote and simplified logger. Added the "-t" option, and made it
397 behave itself a bit better.
398 * Optional support contributed by Ben Collins <bcollins@debian.org>
399 for the kernel init chroot patch by Werner Almesberger, which
400 allows init to chroot to a new device, and umount the old one.
401 * Fixed bug that wouldn't let one chown a symlink -- it would
402 always dereference before. -beppu
403 * Fixed a bug where init could have reference already freed memory.
404 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
405 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
406 * Added (and documented) "-n" option for head
407 * Cleanup for a number of usage messages -- also
408 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
409 * Cosmetic fix to busybox.c (Don't print a comma at the
410 end of line if there are no more application names).
411 * Fixed a stupid bug in "head" option handling ("head -n"
413 * Moved commonly used functions "xmalloc()" and "exit()"
414 to utility.c (with proper #ifdef's).
415 * Created a tiny tail implementation, removing -c, -q, -v, and making
416 tail -f work only with a single file. This reduced tail from 6k to
417 2.4k. The bigger/more featured tail can still be had by disabling
418 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
419 * Ping now falls back to doing the right thing if /etc/protocols
421 * Fixed mount and umount. Previously they could leak loop device
422 allocations, causing the system to quickly run out. Fix for umount
423 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
424 * ls formatting on eight charactor user names fixed by
425 Randolph Chung <tausq@debian.org>.
426 * cp could, when copying symlinks, change permissions of the
427 files pointed to by the symlinks.
428 * Several fixes from Pavel Roskin <proski@gnu.org>:
429 - `chown' with 1 argument displayed the error incorrectly
430 - `fdflush', `length' and `printf' crashed if run without arguments
431 - `fdflush' tried to flush itself using *argv
432 - added "skip" and "seek" to dd.
433 - ls no longer messus up output when combining files and
434 directories on the command line
435 * swapoff -a was not working. Now it is.
436 * init did not cleanly unmount filesystems on reboot. Now it does.
437 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
439 * Some architectures (PowerPc) assume chars are unsigned, so they could
440 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
441 * Began converting error handling to use some common routines
443 * syslogd now has better message handling and ignores SIGHUP.
444 * install.sh had a bug preventing installation to the specified
445 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
446 * You can now spefify alternative strip commands -- change
447 also from Gilbert Coville.
453 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
454 by Edward Betts <edward@debian.org>
455 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
456 type commands (file in a directory to another directory) from
458 * Fixed a logger bug that caused garbage to be written to the syslog
459 (unless you used busybox syslog, which hid the bug). Thanks to
460 Alex Holden <alex@linuxhacker.org> for the fix.
461 * /bin/true and /bin/false were echoing a blank line when run.
463 * mkdir -p would print an error when asked to mkdir an existing dir
464 with no interveining subdirectories.
465 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
466 * and support in umount for loop
467 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
468 <bcollins@debian.org>
469 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
470 * fullWrite() not only if BB_TAR is defined, but also
471 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
472 * add some compiler optimizations to further reduce executable size
473 (as a side note, on my machines the largest code is generated
474 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
476 * Compile now won't fail if busybox.def.h defines
477 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
478 referenced, but not compiled)
479 * Fixed a bug in setting TERM for serial console support. TERM now
480 defaults to "ansi" for serial consoles.
481 * Fixed a bug in handling the CONSOLE env. variable for serial
484 -Erik Andersen, Jan 15, 2000
487 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
488 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
489 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
490 for loading application character maps for Unicode fonts.
491 * Major init re-work. init now supports inittab (slightly different
492 but similar to sysvinit), allowing me to get all the policy out of
493 init and into the conf file. It works just fine without inittab
494 being present, but if you dont like the defautl behavior you can
495 now do something about it. Init is much cleaner as a result.
496 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
497 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
498 * failure of 'logger -p'. -erik Added the -s option to du -beppu
499 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
500 with the 2.0.x Linux kernel.
501 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
503 * Grep -i previously failed on UPPER CASE patterns due to a silly
504 regexp implementation bug that is now fixed.
505 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
506 * Fixed a bug where tar would not set the user and group on device
508 * Fixed a bug where tar would not restore the time to files. Fixed a
509 * major security problem with tar -- it changed ownership
510 of any file pointed to by a symlink to 777 (like say libc....)
512 * cp and mv were very broken when moving directories. I have rewritten
513 them so they should now work as expected.
514 * sed now supports addresses (numeric or regexp, with negation) and
515 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
516 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
517 * Some cosmetic fixes to ls output formatting to make it behave more
519 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
520 * <fwv@myrtle.lahn.de>:
521 - Added gunzip -t, removed gunzip.c dead code,
522 - fixed several typos
523 - Glibc 2.0.7 and libc5 compile fixes
524 * Fixed a bug where 'mknod --help' would segfault.
527 -Erik Andersen, Jan 07, 2000
530 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
531 <tausq@debian.org>. 3 items off the TODO list!
532 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
533 * tail from GNU textutils-1.19, but adjusted
534 to suit my evil purposes. Costs 6k. I'll make it smaller
536 * on reboot, init called 'umount -a -n', which caused errors
537 when BB_MTAB was not enabled. Changed to 'umount -a', which does
539 * init will now try to run /sbin/getty if it is present (for easy
540 integration with the about-to-be-released tinylogin.)
541 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
542 * -l' was failing on long directories, since my_getid was leaking
543 one file descriptor per file. Oops.
544 * Fixed rebooting from init. I'd accidently left some debugging code
546 which blocked reboots.
547 * Fixed reboot, halt (and added poweroff) such that they handle it when
548 init is not at PID 1 (like when running in an initrd).
549 * Added a prelinary du implementation. Some parameter parsing
550 stuff still needs to be added. -beppu (John Beppu
552 * Implemented tee. -beppu Implemented head. -beppu
554 -Erik Andersen, Dec 10, 1999
557 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
559 * df will not exit on error, but will stat all mounted filesystems.
560 * Fixed tar so uid/gid/permissions on extracted tarballs will be
562 * Fixed find -name so it properly uses shell wildcard patterns
563 (i.e. `*', `?', and `[]') instead of regular expressions, which
564 was causing some confusing and unexpected behavior.
565 * Added klogd to syslogd, so now the log will contain both system and
567 * syslogd now creates the /dev/log socket to make sure it is there, and
568 is actually a socket with the right permissions.
569 * I've taken a first step to making busybox not need the /proc
570 filesystem. Most apps don't need it. Those that _require_ it,
571 will complain if you enable them when you disable
572 BB_FEATURE_USE_PROCFS.
574 -Erik Andersen, Dec 5, 1999
577 * Wrote a micro syslogd, and a logger util (to log things to the syslog
578 from the command line or scripts) With both compiled in, costs 4k.
579 * Fixed 'make install' so symlinks are installed in their proper
580 * locations. Changed the build system slightly so that features can
582 or disabled from the busybox.defs.h header file, without trying to
583 compile in a source file named after that featue (unless that file
585 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
586 * -r' both work. dd now properly handles input beyond 1 block from
587 * stdin. Fixed a bug where tar unpacked everything a directories.
589 from createPath into mkdir where it belonged, thereby making tar
591 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
593 last file in the list.
594 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
596 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
597 are presented properly.
601 -Erik Andersen, Nov 25, 1999
604 * fixed dd so it properly defaults to stdin and stdout when no
605 if= and of= are set (fix thanks to Eric Delaunay).
606 * Don't try to close the file descriptor of a pipein tar. (fix also
609 * Made createPath be quiet (again thanks to Eric Delaunay). If
610 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
611 command you define it as will be run if the init script exits.
612 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
613 * NFS support added to mount by Eric Delaunay. It costs 10k when
615 in, but that is still a big win for those that use NFS.
616 * Made 'rm -f' be silent for non-existant files (thanks to Eric
617 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
619 and acts as god intended gunzip and zcat to act. They answer
620 --help and obey the '-c' flag.
621 * Fixed a bug in mv which caused it to not move files when the
624 * Fixed a decimal-instead-of-octal bug causing mkdir to make
626 with very wrong permissions.
627 * chmod would overwrite file permissions instead of modifying them.
628 Now it properly modifies permissions.
629 * Init now sends warnings destined for the console to /dev/console to
631 they show up on whatever the active console it. Otherwise
632 important messages (for example that the system is rebooting) were
633 not seen when switched to a different VT.
635 -Erik Andersen, Nov 17, 1999
638 * gzip now obeys the principle of least surprise and acts like god
640 (i.e. it accepts a file name, answers --help, and obeys the '-c'
641 flag and only then outputs to stdout).
642 * Fixed more.c to compile autowidth on sparc and set initial winsize
643 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
645 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
646 * tar now accepts --help chmod, chown, and chgrp usage now works
647 * General usage (i.e. --help) cleanups for most apps umount now parses
648 * options correctly tar can now unpack tarballs containing device
650 sockets, and fifos (though it can't pack them up) thanks to Matt
651 Porter. Creating archives containing these is still left to the
653 * fixed up the license in more.c to properly point to Bruce Perens.
655 -Erik Andersen, Nov 11, 1999
658 * ls -l now displays link names outside the current directory,
659 Patch thanks to Eric Delaunay
660 * init now properly handles sparc serial consoles and does a
661 better job of finding the real console device rather than using
662 /dev/console which doesn't support job control. Patch also thanks
664 * more started to read from stdin after the last file was finished, and
665 options were not parsed correctly (fix thanks to Eric Delaunay).
666 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
667 * rm wouldn't remove a symlink unless the symlink was valid. This was
668 a side effect of the busybox 0.32 recursiveAction() fix. Things
669 should now work correctly.
670 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
671 * it does. sed was appending a \n to the end of lines with
673 Now it doesn't do that.
674 * ls -l now bypasses libc6 nss when displaying user/group names.
675 Now uses my_getpwuid and my_getgrgid.
677 -Erik Andersen, Nov 8, 1999
680 * Fixed a bug where init could hang instead of rebooting.
681 * Removed some debugging noise from init.c
682 * Fixed ln so it works now (it was very broken).
683 * Fixed df so it won't segfault when there is no /etc/fstab,
684 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
685 is not installed (since they cannot fixup "/dev/root" to
686 state the real root device name)
687 * merged some redundant code from mtab.c/df.c into utility.c
689 -Erik Andersen, Nov 5, 1999
692 * More changes -- many thanks to Lineo for paying me to work on
693 busybox. If you have any problems please let me know ASAP at
694 andersen@lineo.com or andersee@debian.org
695 * usage() now prints the BusyBox version. This will help folks
696 realize that they are not in Kansas anymore.
697 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
698 * arguments. Now it doesn't do that. kill wasn't properly accepting
699 * signal names. It does now. Added new apps chvt and deallocvt (I
700 * should probably add open) Major rewrite of init.c. Code is now
701 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
702 * with full regular expressions!). Fixed a stupid seg-fault in sync
703 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
704 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
705 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
706 * cost of ~1.5k and the need for a rw /etc)
707 folks to use a real /etc/mtab file instead of a symlink to
708 /proc/mounts. mount, and umount will add/remove entries and df
709 will now use /etc/mtab if BB_MTAB is defined.
710 * Fixed a nice bug in recursiveAction() which caused it to infinitely
711 hunt through /proc/../fd/* creating new file descriptors if it
712 followed the /dev/fd link over to /proc. recursiveAction() now
713 lstat's the file when followLinks==FALSE so it won't follow links
714 as the name suggests. Fix thanks to Matt Porter
718 -Erik Andersen, Nov 4, 1999
721 * I added a changelog for version 0.30. adjusted find internals to
722 * make it smaller, and removed
724 * Fixed a segfault in ps when /etc/passwd or /etc/group
725 are absent. Now will warn you and carry on.
726 * Added in optional _real_ regular expression support (to be
727 the basis for a future sed utility). When compiled in it adds
728 3.9k, but makes grep much more capable.
729 * Checked out using nftw(3) for recursive stuff, but unfortunatly
730 it wasn't supported before GNU libc 2.1, and some folks use glibc
731 2.0.7 since it is much smaller than that latest and greatest.
733 -Erik Andersen, Oct 21, 1999
736 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
737 paying me to make these updates. If you have any problems with busybox,
738 or notice any bugs -- please let me know so I can fix it. These
742 * busybox can now invoke apps in two ways: via symlinks to the
743 busybox binary, and as 'busybox [function] [arguments]...'
744 * When invoked as busybox, the list of currently compiled in
745 functions is printed out (no this is not bloat -- the list has
746 to be there anyway to map invocation name to function).
747 * busybox no longer parses command lines for apps or displays their
748 usage info. Each app gets to handle (or not handle) this for
750 * Eliminated monadic, dyadic, descend, block_device, and
751 postprocess. It was cumbersome to have so many programs
752 cobbled together in this way. Without them, the app is much
754 * All shared code now lives in utility.c, and is properly
755 ifdef'ed to be only included for those apps requiring it.
756 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
757 so now each app has the function prototype of (da-dum): extern
758 int foo_main(int argc, char** argv); which speeds integration
760 * Adjusted the Makefile to make it easier to
761 {en|dis}able debugging.
762 * Changed default compiler optimization to -Os
763 (optimize for smaller binaries).
766 * To cope with the new app function prototype and the removal of
767 monadic, dyadic, etc, the following apps were re-written:
768 * cat - Works same as always. chgrp, chmod, chown -
769 * rewrite. Combined into a single
770 source file. Absorbed patches from Enrique Zanardi
771 <ezanard@debian.org> that removes the dependency on
772 libc6 libnss* libraries.
773 * cp - Can now do 'cp -a' can can copy devices,
774 pipes, symlinks, as well as recursive or non-recursive
776 * fdflush - adjusted to remove dependancy on struct
777 * FileInfo. find - Now includes some basic regexp matching
778 which will be the basic of a future mini-sed.
779 * ln - Same functionality. mkdir - Added -p flag to
780 * feature set. mv - rewrite. rm - Added -f flag to
781 * feature set. rmdir - Same functionality. swapon,
782 * swapoff - Combined into a single binary. No longer
783 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
785 * touch - Same functionality. date - adjusted with a patch
786 * from Matthew Grant <grantma@anathoth.gen.nz>
787 to accomodate glibc timezone support. I then ripped out GNU
789 * mkswap -- new version merged from util-linux. Can now make
791 * Replaced the old and star, unstar, and tarcat with the tar
792 implementation from sash. Now tar behaves as god intended it
793 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
794 * dd -- rewritten. Can with with files, stdin, stdout. Added the
795 * following new apps: loadfont -- added from debian boot floppies
796 * chroot -- added based on a patch from Paolo Molaro
797 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
798 * simple strings ps -- I just wrote it. Has _no_ options at all,
799 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
801 internationalization and such to make them smaller.
802 * sfdisk -- Added from util-linux (minus
803 * internationalization and such). Probably some other
804 * changes that I forgot to document...
806 -Erik Andersen, Oct 20, 1999
809 This version was a messy pre-alpha. stay away or it will bite you.
810 -Erik Andersen, Sep 24, 1999
813 mini-netcat (mnc) rewritten.
816 Mount now supports -a, and -t auto.
817 Mount now updates mtab correctly for 'ro'.
818 More checks screen rows size, outputs bytes percentage.
819 Printf added as module.
821 Touch now creates files. -c option for no create.
