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