3 * Fixed uname problem causing the kernel version to be
4 mis-detected (causing problems with poweroff, init,
6 * Kent Robotti -- Renamed unrpm to original rpmunpack, so you can use
7 an included shell script called unrpm as a front end to it. There's
8 also a shell script called undeb included for debian packages.
9 * Matt Kraai -- fix an infinate loop with ls -aR
10 * Larry Doolittle -- Shaves off about 100 bytes and 200 bytes heap
11 from date.c. Also document the "-d" option in the usage message.
12 * Gennady Feldman -- fixed dd to use blocksize when reading/writing,
13 (it was reading the whole thing and then writing it out). Also
14 updated usage information (was missing conv=notrunc) and added
16 * Larry Doolittle (in collaboration with Matt Kraai) to allow for a
17 pristine source directory -- where all the .o files and such are
18 not placed into the source tree. Thanks Larry!
24 * A bug in syslogd was fixed that allowed it to potentially fork-bomb
25 your system. Anyone using 0.46 syslogd should upgrade.
26 * Renamed busybox.defs.h to the more sensible "Config.h"
27 * Improved portability between different libcs.
28 * Many apps ported to use getopt()
29 * Common handling of '--help'
30 * All usage messages centralized.
31 * Added a bunch of new commands:
32 * 'rdate' contributed by Sterling Huxley <sterling@europa.com>
33 * 'wget' contributed by Chip Rosenthal <chip@unicom.com>,
34 <crosenth@covad.com> and Covad Communications
35 * 'getopt' from "Alfred M. Szmidt" <ams@trillian.itslinux.org>
36 * dos2unix, unix2dos, reset, and unrpm.c (and lots of help
37 debugging) thanks to Kent Robotti <robotti@metconnect.com>.
38 * 'renice' command, thanks to Dave Cinege <dcinege@psychosis.com>
39 * 'xargs' (written by me)
40 * 'expr' contributed by Edward Betts <edward@debian.org>, based
42 * lsmod now uses the query_module syscall, rather then /proc (me)
43 * syslogd can now log messages to remote hosts -- patch thanks
44 to Gyepi Sam <gyepi@praxis-sw.com>
45 * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>
46 * 'make install' now creates relative symlinks, and added a new
47 'make install-hardlinks' target to (tada) install hardlinks.
48 * Rewrite of 'tail' to make it simpler, smaller, and more robust.
49 It now weighs only 2.25k (3k when full featured). The code is
50 cleaner too, thanks to Allen Soard <esp-software@mail.hypermart.net>
51 * Add optional ls file sorting, thanks to a patch from
52 Sterling Huxley <sterling@europa.com>
53 * Fixed chmod option parsing so things like 'chmod -r /tmp/file'
54 now work (previously it thought -r was an option). Doh!
55 * Fixed tar handling of stdin and stdout
56 * Renamed "internal.h" to the more sensible "busybox.h"
57 * Preliminary support for GNU HURD.
58 * Updated my devps and devmtab kernel patches for the latest 2.2.x
59 kernel, for those wanting to go proc-less.
60 * Tons of other bugfixes.
63 -Erik Andersen, 25 September 2000
68 * Better portability. Now should compile cleanly with libc5,
69 GNU libc 2.0 and 2.1, and various Linux kernels including
70 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
71 to make /proc/mounts behave included in the kernel-patches dir).
72 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
73 local files that matched tarball contents!!! Fix thanks
74 to Marius Groeger <mgroeger@sysgo.de>
75 * Fixed a nasty bug in tar when could mess up saved symlinks.
76 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
77 thanks to Daniel Quinlan <quinlan@transmeta.com>
78 * Updates to handle Linux 2.4.0 kernels (kludged around the
79 "none" entries in /proc/mounts, added a hack to make sysinfo
80 work with both old and new kernels).
81 * Fixed insmod module option parsing for options lacking an '='.
82 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
83 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
84 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
85 * Several fixes from Marius Groeger <mag@sysgo.de>
86 - Added support for "sh -c command args..."
87 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
88 - Added shell environment variable substitution
89 - Added the "read" shell builtin.
90 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
91 used to create an infinite loop: ls, cursor up, left, down.
92 * Added support for being a login shell, so things like
93 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
94 invoke the shell. Now you can use BusyBox as a login shell.
95 * ls.c now ignores '-g', since some ftp clients like that sort
96 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
97 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
98 it always sets the controlling terminal before running any programs
99 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
100 - Fixed tr so it recognizes standard escape sequences.
101 Merged common escape seq. code from tr and echo into utility.c.
102 - Major work in updating/cleaning up the docs, and getting the
103 new SGML based docs into shape.
105 - BusyBox should now poweroff when asked to do so.
106 - Fixed 'ln -n' and 'ln -s' so they both work properly.
107 * Reorganized signal names in kill.c for better architecture support
108 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
109 * In 0.43, backspace and delete worked properly, but with 0.45,
110 it just echoed a ^? for backspace, and ^H for control-h. This
111 was due to a broken macro in init.c, that is now fixed.
112 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
113 couldn't maintain it very well, so including it was not really
114 very appropriate. Those wanting an fdisk are invited to
115 grab a copy from util-linux.
116 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
117 then be loaded in by 'loadkmap' -- submitted by
118 Arne Bernin <arne@matrix.loopback.org>
119 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
120 * Brand, new versions of grep and sed which use libc regex routines,
121 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
122 "regexp.[ch]" files have been removed. Much help on these from
126 -Erik Andersen, 11 July 2000
130 * Now compiles vs libc5 (which can save lots of space for
132 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
133 help messages (i.e --help). Saves 17k over a full compile.
134 * Added cut and tr from minix, since due to the license change,
135 we can now use minix code. Minix tr saves 4k.
136 * insmod now works. It costs 29k, but imagine an initrd with a
137 staticly linked busybox containing only insmod and sh, a few /dev
138 entries, and a kernel module or two... It doesn't get smaller
139 then this folks (I pity the fool that writes insmod in asm ;-).
140 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
141 * Added a mini ar archive utility, especially written for BusyBox by
142 Glenn McGrath <bug1@netconnect.com.au>
143 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
144 * Added setkeycodes, for those that have wierd keyboard buttons.
145 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
146 <ams@trillian.itslinux.org> for contributing these.
147 * Added 'grep -v' option (inverted search) and updated
148 docs accordingly. -beppu
150 * Replaced the telnet implementation with one written by
151 Tomi Ollila <too@iki.fi> It works great and costs 3k.
152 * BusyBox sh (lash) now supports being used as a standalone shell. When
153 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
154 be invoked as shell internals. Best used when compiling staticly
156 * BusyBox sh (lash) internals now behave as expected wrt pipes
158 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
159 * Fixed update segfault
160 * Fixed mknod -- minor number was always 0
161 * Fixed tar option parsing, so both "tar xvf foo.tar" and
162 "tar -xvf foo.tar" now work (i.e. no "-" before options)
163 (this was very broken in 0.43).
164 * Several contributions from Randolph Chung <tausq@debian.org>.
165 * cp/mv now accepts the -f flag
166 * tail can now accept -<num> commands (e.g. -10) for better
167 compatibility with the standard tail command
168 * added a simple id implementation; doesn't support sup. groups yet
169 * logname used getlogin(3) which uses utmp. Now it doesn't.
170 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
171 * Add support for "noatime" and "nodiratime" mount flags to mount.
172 * Changed 'umount -f' to mean force, and actually use umount2.
173 * Changed 'umount -l' to mean "Do not free loop device".
174 * Fixed basename to support stripping of suffixes. Patch thanks
175 to xiong jianxin <jxiong@uiuc.edu>
176 * cp -fa now works as expected for symlinks (it didn't before)
177 * zcat now works (wasn't working since option parsing was broken)
178 * Renamed "mnc" to the more correct "nc" (for netcat).
179 * Makefile intelligence updates
180 * Changed the way init parses /etc/inittab entries to avoid problems
181 with commands that contain colons in them. Fix thanks to
182 Pavel Roskin <proski@gnu.org>
183 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
184 Fix thanks to Pavel Roskin <proski@gnu.org>
185 * Made "killall" complain (not error and exit) about processes that it
186 cannot find by name -- Pavel Roskin <proski@gnu.org>
187 * Fixed more and ps to have sensible terminal width defaults, thanks
189 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
190 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
191 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
192 * Fixed segfault caused by "touch -c"
193 * Fixed segfault caused by "rm -f"
194 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
195 and "--" support from Pavel Roskin.
196 * Fixed segfault caused by "cp -a -a" and similar abuses.
197 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
198 * "which" rewritten to use stat(). Fixes to improve its compatability
199 with traditional implementations -- Pavel Roskin.
200 * "mount" now reports errors from nfsmount() and assumes NFS mount
201 if ':' is present in the device name - Pavel Roskin
202 * Fixed exit status for killall - Pavel Roskin
203 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
204 * Fixed 'mount -a' so it works as expected.
205 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
206 * Implemented "ping -s", fixed error messages and argument parsing -
208 * Syslogd will not go to background if "-n" is given. Better help
209 and argument checking -- Pavel Roskin
210 * Fixed a small bug that could cause tar to emit warning messages
211 and not extract the first file in a directory in some cases
212 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
213 for helping track this one down.
215 * Fixed grep "Line too long" problem -- John Beppu
216 * Fixed 'grep -q -i B some_file' so it works
217 * math takes input from stdin if no args are given. -- John Beppu
218 * math was renamed to dc. Although it deviates from dc's behaviour,
219 this will probably be remedied in the future. -- John Beppu
222 -Erik Andersen, June 21, 2000
226 Previously, an erronous announcement of BusyBox 0.44 was made, so to
227 avoid possible confusion, we are skipping straight to 0.45, and calling
234 * Major update to the provided documentation.
235 * Busybox now includes a shell! It currently costs 7.5 k (plus an
236 additional 2.5 k if you compile in command line editing). Handles
237 job control, has the usual set of builtins, and does everything
238 except for handling programming statements (if, while, etc...)
239 * Busybox can now work perfectly when /proc is disabled, thereby
240 saving a bunch of memory (kernel /proc support is not thin). This
241 is done by making use of some nice kernel patches I wrote up to
242 support the features that busybox requires and that /proc usually
243 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
244 patch your kernel with the devps patch in the kernel-patches/
246 * Wrote basename, dirname, killall, and uptime.
247 * tar has been completely rewritten by me. Both tar creation and
248 extraction are now well behaved. Costs 7.6k with all optional
249 tar features enabled, and 5k for just tar extraction support.
250 * Added freeramdisk, which will free up all memory associated
251 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
252 and then adjusted a bit by me.
253 * Added tr from John Lombardo <john@deltanet.com>
254 * Added echo and test (from me).
255 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
256 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
257 * Several fixes from Pavel Roskin <proski@gnu.org>:
258 - When `tail' fails to open a file it now exits.
259 - When `syslogd' is given the `-n' option it should still use
260 fork() for running klogd.
261 * nslookup types are now changed to u_int32_t (instead of uint32_t)
262 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
263 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
264 to count hard-linked files more then once). Many thanks to
265 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
266 * Removed /proc dependancies for init and free (while maintaining
267 exactly the same functionality). /proc takes up 90k of kernel
268 space, so it is nice to avoid using it at all costs.
269 * init no longer tries to mount /proc (unless there is less the 1 meg
270 free). Use of /proc (or not) is policy that should be set up in
271 /etc/fstab (or in hardcoded scripts), not in init.
272 * Fixed rebooting when init runs as an initrd.
273 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
274 - update.c rewritten to look more like update-2.11
275 - moveed the inode hash out of du.c and into utility.c to make
276 it a common resource that can be used by other apps.
277 - cp_mv.c now checks inodes to see if a source and dest are
278 the same, and prints an error (instead of endlessly looping).
279 - mv now attempts to do a rename, and will fall back to doing
280 a copy only if the rename fails.
281 - Syslogd now supports multiple concurrent connections
282 * Several fixes from Pavel Roskin <proski@gnu.org>:
283 - Fixes to sort. Removed "-g", fixed and added "-r"
284 - Fixes to the makefile for handling "strip"
285 * An initial telnet implementation was added by
286 Randolph Chung <tausq@debian.org>.
287 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
288 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
289 to match the terminal (defaults to width=79 when this is off).
290 * ps now accepts (and ignores) all options except for "--help" (which
291 as would be expected displays help).
292 * Fixed mount'ing loop devices when the filesystem type was not
293 specified. It used to revert to non-loop after the first try.
294 * all mallocs now use xmalloc (and so are OOM error safe), and
295 the common error handling saves a few bytes. Thanks to
296 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
297 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
298 * Fix symlink following bug in chmod -R and friends.
299 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
300 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
309 * Fairly massive restructuring of umount.c to deal with remounting
310 busy devices read-only. Adds a -r option to control that; it is
311 optionally compiled in with BB_FEATURE_REMOUNT
312 * Added a bunch of functions to mtab.c to interact with the
313 {get,set,end}mntent interface; as it turns out, those functions do
314 not appear to be re-entrant, and that causes a lot of problems with
315 the way umount was originally written.
316 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
317 to be more consistent with sysvinit
318 * Changes to init.c to use the new -r option to umount. Also increased
319 the sleep time between the time the TERM and KILL signals are sent
324 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
325 extensively rewritten from the original cp.c.
326 * Fixed cp and mv so if the source and destination are a the
327 same directory it will print an error and continue.
328 * Also added a warning message to the `mv' usage string saying that
329 this is not GNU mv, and it will break hard links. cp also breaks
331 * ln.c: implemented `-n' switch, no-deref symlinks.
332 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
333 * name buffer overrun guards to prevent future crashes.
334 - Always check exit status.
335 - Purge all use of `creat()', replace with `open()'.
337 - recursiveAction was overriding the value of followLinks thus
339 - isDirectory now takes a followLinks boolean, updated all callers
340 - copyFile had the followLinks logic reversed.
341 * messages.c: New file. Put common error message strings all in
342 one place in an attempt to shrink the binary a little.
347 * changed fsck_minix.c to reduce its .bss size significantly
349 * Made tar creation support in busybox tar optional. You no longer
350 * _have_ to put a "-" in front of tar options. Tar could inadvertently
351 * change permissions and ownership on
352 certain directories pointed to by symlinks.
353 * Made grep and grep -h do the right thing wrt printing
354 the file name (it failed to print files names in many cases).
355 * Fix a namespace aliasing problem wereby if du was built in, the
356 symlink for both du and dutmp would be installed, or then rm was
357 built in, the symlinks for both rm and rmmod would be installed.
358 * Added a closelog() to init.c after loging -- fix thanks to
359 Taketoshi Sano <kgh12351@nifty.ne.jp>
360 * Rewrote and simplified logger. Added the "-t" option, and made it
361 behave itself a bit better.
362 * Optional support contributed by Ben Collins <bcollins@debian.org>
363 for the kernel init chroot patch by Werner Almesberger, which
364 allows init to chroot to a new device, and umount the old one.
365 * Fixed bug that wouldn't let one chown a symlink -- it would
366 always dereference before. -beppu
367 * Fixed a bug where init could have reference already freed memory.
368 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
369 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
370 * Added (and documented) "-n" option for head
371 * Cleanup for a number of usage messages -- also
372 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
373 * Cosmetic fix to busybox.c (Don't print a comma at the
374 end of line if there are no more application names).
375 * Fixed a stupid bug in "head" option handling ("head -n"
377 * Moved commonly used functions "xmalloc()" and "exit()"
378 to utility.c (with proper #ifdef's).
379 * Created a tiny tail implementation, removing -c, -q, -v, and making
380 tail -f work only with a single file. This reduced tail from 6k to
381 2.4k. The bigger/more featured tail can still be had by disabling
382 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
383 * Ping now falls back to doing the right thing if /etc/protocols
385 * Fixed mount and umount. Previously they could leak loop device
386 allocations, causing the system to quickly run out. Fix for umount
387 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
388 * ls formatting on eight charactor user names fixed by
389 Randolph Chung <tausq@debian.org>.
390 * cp could, when copying symlinks, change permissions of the
391 files pointed to by the symlinks.
392 * Several fixes from Pavel Roskin <proski@gnu.org>:
393 - `chown' with 1 argument displayed the error incorrectly
394 - `fdflush', `length' and `printf' crashed if run without arguments
395 - `fdflush' tried to flush itself using *argv
396 - added "skip" and "seek" to dd.
397 - ls no longer messus up output when combining files and
398 directories on the command line
399 * swapoff -a was not working. Now it is.
400 * init did not cleanly unmount filesystems on reboot. Now it does.
401 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
403 * Some architectures (PowerPc) assume chars are unsigned, so they could
404 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
405 * Began converting error handling to use some common routines
407 * syslogd now has better message handling and ignores SIGHUP.
408 * install.sh had a bug preventing installation to the specified
409 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
410 * You can now spefify alternative strip commands -- change
411 also from Gilbert Coville.
417 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
418 by Edward Betts <edward@debian.org>
419 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
420 type commands (file in a directory to another directory) from
422 * Fixed a logger bug that caused garbage to be written to the syslog
423 (unless you used busybox syslog, which hid the bug). Thanks to
424 Alex Holden <alex@linuxhacker.org> for the fix.
425 * /bin/true and /bin/false were echoing a blank line when run.
427 * mkdir -p would print an error when asked to mkdir an existing dir
428 with no interveining subdirectories.
429 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
430 * and support in umount for loop
431 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
432 <bcollins@debian.org>
433 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
434 * fullWrite() not only if BB_TAR is defined, but also
435 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
436 * add some compiler optimizations to further reduce executable size
437 (as a side note, on my machines the largest code is generated
438 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
440 * Compile now won't fail if busybox.def.h defines
441 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
442 referenced, but not compiled)
443 * Fixed a bug in setting TERM for serial console support. TERM now
444 defaults to "ansi" for serial consoles.
445 * Fixed a bug in handling the CONSOLE env. variable for serial
448 -Erik Andersen, Jan 15, 2000
451 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
452 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
453 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
454 for loading application character maps for Unicode fonts.
455 * Major init re-work. init now supports inittab (slightly different
456 but similar to sysvinit), allowing me to get all the policy out of
457 init and into the conf file. It works just fine without inittab
458 being present, but if you dont like the defautl behavior you can
459 now do something about it. Init is much cleaner as a result.
460 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
461 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
462 * failure of 'logger -p'. -erik Added the -s option to du -beppu
463 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
464 with the 2.0.x Linux kernel.
465 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
467 * Grep -i previously failed on UPPER CASE patterns due to a silly
468 regexp implementation bug that is now fixed.
469 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
470 * Fixed a bug where tar would not set the user and group on device
472 * Fixed a bug where tar would not restore the time to files. Fixed a
473 * major security problem with tar -- it changed ownership
474 of any file pointed to by a symlink to 777 (like say libc....)
476 * cp and mv were very broken when moving directories. I have rewritten
477 them so they should now work as expected.
478 * sed now supports addresses (numeric or regexp, with negation) and
479 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
480 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
481 * Some cosmetic fixes to ls output formatting to make it behave more
483 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
484 * <fwv@myrtle.lahn.de>:
485 - Added gunzip -t, removed gunzip.c dead code,
486 - fixed several typos
487 - Glibc 2.0.7 and libc5 compile fixes
488 * Fixed a bug where 'mknod --help' would segfault.
491 -Erik Andersen, Jan 07, 2000
494 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
495 <tausq@debian.org>. 3 items off the TODO list!
496 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
497 * tail from GNU textutils-1.19, but adjusted
498 to suit my evil purposes. Costs 6k. I'll make it smaller
500 * on reboot, init called 'umount -a -n', which caused errors
501 when BB_MTAB was not enabled. Changed to 'umount -a', which does
503 * init will now try to run /sbin/getty if it is present (for easy
504 integration with the about-to-be-released tinylogin.)
505 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
506 * -l' was failing on long directories, since my_getid was leaking
507 one file descriptor per file. Oops.
508 * Fixed rebooting from init. I'd accidently left some debugging code
510 which blocked reboots.
511 * Fixed reboot, halt (and added poweroff) such that they handle it when
512 init is not at PID 1 (like when running in an initrd).
513 * Added a prelinary du implementation. Some parameter parsing
514 stuff still needs to be added. -beppu (John Beppu
516 * Implemented tee. -beppu Implemented head. -beppu
518 -Erik Andersen, Dec 10, 1999
521 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
523 * df will not exit on error, but will stat all mounted filesystems.
524 * Fixed tar so uid/gid/permissions on extracted tarballs will be
526 * Fixed find -name so it properly uses shell wildcard patterns
527 (i.e. `*', `?', and `[]') instead of regular expressions, which
528 was causing some confusing and unexpected behavior.
529 * Added klogd to syslogd, so now the log will contain both system and
531 * syslogd now creates the /dev/log socket to make sure it is there, and
532 is actually a socket with the right permissions.
533 * I've taken a first step to making busybox not need the /proc
534 filesystem. Most apps don't need it. Those that _require_ it,
535 will complain if you enable them when you disable
536 BB_FEATURE_USE_PROCFS.
538 -Erik Andersen, Dec 5, 1999
541 * Wrote a micro syslogd, and a logger util (to log things to the syslog
542 from the command line or scripts) With both compiled in, costs 4k.
543 * Fixed 'make install' so symlinks are installed in their proper
544 * locations. Changed the build system slightly so that features can
546 or disabled from the busybox.defs.h header file, without trying to
547 compile in a source file named after that featue (unless that file
549 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
550 * -r' both work. dd now properly handles input beyond 1 block from
551 * stdin. Fixed a bug where tar unpacked everything a directories.
553 from createPath into mkdir where it belonged, thereby making tar
555 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
557 last file in the list.
558 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
560 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
561 are presented properly.
565 -Erik Andersen, Nov 25, 1999
568 * fixed dd so it properly defaults to stdin and stdout when no
569 if= and of= are set (fix thanks to Eric Delaunay).
570 * Don't try to close the file descriptor of a pipein tar. (fix also
573 * Made createPath be quiet (again thanks to Eric Delaunay). If
574 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
575 command you define it as will be run if the init script exits.
576 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
577 * NFS support added to mount by Eric Delaunay. It costs 10k when
579 in, but that is still a big win for those that use NFS.
580 * Made 'rm -f' be silent for non-existant files (thanks to Eric
581 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
583 and acts as god intended gunzip and zcat to act. They answer
584 --help and obey the '-c' flag.
585 * Fixed a bug in mv which caused it to not move files when the
588 * Fixed a decimal-instead-of-octal bug causing mkdir to make
590 with very wrong permissions.
591 * chmod would overwrite file permissions instead of modifying them.
592 Now it properly modifies permissions.
593 * Init now sends warnings destined for the console to /dev/console to
595 they show up on whatever the active console it. Otherwise
596 important messages (for example that the system is rebooting) were
597 not seen when switched to a different VT.
599 -Erik Andersen, Nov 17, 1999
602 * gzip now obeys the principle of least surprise and acts like god
604 (i.e. it accepts a file name, answers --help, and obeys the '-c'
605 flag and only then outputs to stdout).
606 * Fixed more.c to compile autowidth on sparc and set initial winsize
607 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
609 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
610 * tar now accepts --help chmod, chown, and chgrp usage now works
611 * General usage (i.e. --help) cleanups for most apps umount now parses
612 * options correctly tar can now unpack tarballs containing device
614 sockets, and fifos (though it can't pack them up) thanks to Matt
615 Porter. Creating archives containing these is still left to the
617 * fixed up the license in more.c to properly point to Bruce Perens.
619 -Erik Andersen, Nov 11, 1999
622 * ls -l now displays link names outside the current directory,
623 Patch thanks to Eric Delaunay
624 * init now properly handles sparc serial consoles and does a
625 better job of finding the real console device rather than using
626 /dev/console which doesn't support job control. Patch also thanks
628 * more started to read from stdin after the last file was finished, and
629 options were not parsed correctly (fix thanks to Eric Delaunay).
630 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
631 * rm wouldn't remove a symlink unless the symlink was valid. This was
632 a side effect of the busybox 0.32 recursiveAction() fix. Things
633 should now work correctly.
634 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
635 * it does. sed was appending a \n to the end of lines with
637 Now it doesn't do that.
638 * ls -l now bypasses libc6 nss when displaying user/group names.
639 Now uses my_getpwuid and my_getgrgid.
641 -Erik Andersen, Nov 8, 1999
644 * Fixed a bug where init could hang instead of rebooting.
645 * Removed some debugging noise from init.c
646 * Fixed ln so it works now (it was very broken).
647 * Fixed df so it won't segfault when there is no /etc/fstab,
648 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
649 is not installed (since they cannot fixup "/dev/root" to
650 state the real root device name)
651 * merged some redundant code from mtab.c/df.c into utility.c
653 -Erik Andersen, Nov 5, 1999
656 * More changes -- many thanks to Lineo for paying me to work on
657 busybox. If you have any problems please let me know ASAP at
658 andersen@lineo.com or andersee@debian.org
659 * usage() now prints the BusyBox version. This will help folks
660 realize that they are not in Kansas anymore.
661 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
662 * arguments. Now it doesn't do that. kill wasn't properly accepting
663 * signal names. It does now. Added new apps chvt and deallocvt (I
664 * should probably add open) Major rewrite of init.c. Code is now
665 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
666 * with full regular expressions!). Fixed a stupid seg-fault in sync
667 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
668 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
669 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
670 * cost of ~1.5k and the need for a rw /etc)
671 folks to use a real /etc/mtab file instead of a symlink to
672 /proc/mounts. mount, and umount will add/remove entries and df
673 will now use /etc/mtab if BB_MTAB is defined.
674 * Fixed a nice bug in recursiveAction() which caused it to infinitely
675 hunt through /proc/../fd/* creating new file descriptors if it
676 followed the /dev/fd link over to /proc. recursiveAction() now
677 lstat's the file when followLinks==FALSE so it won't follow links
678 as the name suggests. Fix thanks to Matt Porter
682 -Erik Andersen, Nov 4, 1999
685 * I added a changelog for version 0.30. adjusted find internals to
686 * make it smaller, and removed
688 * Fixed a segfault in ps when /etc/passwd or /etc/group
689 are absent. Now will warn you and carry on.
690 * Added in optional _real_ regular expression support (to be
691 the basis for a future sed utility). When compiled in it adds
692 3.9k, but makes grep much more capable.
693 * Checked out using nftw(3) for recursive stuff, but unfortunatly
694 it wasn't supported before GNU libc 2.1, and some folks use glibc
695 2.0.7 since it is much smaller than that latest and greatest.
697 -Erik Andersen, Oct 21, 1999
700 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
701 paying me to make these updates. If you have any problems with busybox,
702 or notice any bugs -- please let me know so I can fix it. These
706 * busybox can now invoke apps in two ways: via symlinks to the
707 busybox binary, and as 'busybox [function] [arguments]...'
708 * When invoked as busybox, the list of currently compiled in
709 functions is printed out (no this is not bloat -- the list has
710 to be there anyway to map invocation name to function).
711 * busybox no longer parses command lines for apps or displays their
712 usage info. Each app gets to handle (or not handle) this for
714 * Eliminated monadic, dyadic, descend, block_device, and
715 postprocess. It was cumbersome to have so many programs
716 cobbled together in this way. Without them, the app is much
718 * All shared code now lives in utility.c, and is properly
719 ifdef'ed to be only included for those apps requiring it.
720 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
721 so now each app has the function prototype of (da-dum): extern
722 int foo_main(int argc, char** argv); which speeds integration
724 * Adjusted the Makefile to make it easier to
725 {en|dis}able debugging.
726 * Changed default compiler optimization to -Os
727 (optimize for smaller binaries).
730 * To cope with the new app function prototype and the removal of
731 monadic, dyadic, etc, the following apps were re-written:
732 * cat - Works same as always. chgrp, chmod, chown -
733 * rewrite. Combined into a single
734 source file. Absorbed patches from Enrique Zanardi
735 <ezanard@debian.org> that removes the dependency on
736 libc6 libnss* libraries.
737 * cp - Can now do 'cp -a' can can copy devices,
738 pipes, symlinks, as well as recursive or non-recursive
740 * fdflush - adjusted to remove dependancy on struct
741 * FileInfo. find - Now includes some basic regexp matching
742 which will be the basic of a future mini-sed.
743 * ln - Same functionality. mkdir - Added -p flag to
744 * feature set. mv - rewrite. rm - Added -f flag to
745 * feature set. rmdir - Same functionality. swapon,
746 * swapoff - Combined into a single binary. No longer
747 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
749 * touch - Same functionality. date - adjusted with a patch
750 * from Matthew Grant <grantma@anathoth.gen.nz>
751 to accomodate glibc timezone support. I then ripped out GNU
753 * mkswap -- new version merged from util-linux. Can now make
755 * Replaced the old and star, unstar, and tarcat with the tar
756 implementation from sash. Now tar behaves as god intended it
757 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
758 * dd -- rewritten. Can with with files, stdin, stdout. Added the
759 * following new apps: loadfont -- added from debian boot floppies
760 * chroot -- added based on a patch from Paolo Molaro
761 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
762 * simple strings ps -- I just wrote it. Has _no_ options at all,
763 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
765 internationalization and such to make them smaller.
766 * sfdisk -- Added from util-linux (minus
767 * internationalization and such). Probably some other
768 * changes that I forgot to document...
770 -Erik Andersen, Oct 20, 1999
773 This version was a messy pre-alpha. stay away or it will bite you.
774 -Erik Andersen, Sep 24, 1999
777 mini-netcat (mnc) rewritten.
780 Mount now supports -a, and -t auto.
781 Mount now updates mtab correctly for 'ro'.
782 More checks screen rows size, outputs bytes percentage.
783 Printf added as module.
785 Touch now creates files. -c option for no create.
