3 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
4 local files!!! Fix thanks to Marius Groeger <mgroeger@sysgo.de>
5 * Fixed a nasty bug in tar when could mess up saved symlinks.
6 * Updates to handle Linux 2.4.0 kernels (kludged around the
7 "none" entries in /proc/mounts, added a hack to make sysinfo
8 work with both old and new kernels).
9 * Fixed insmod module option parsing for options lacking an '='.
10 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
11 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
12 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
13 * Several fixes from Marius Groeger <mag@sysgo.de>
14 - Added support for "sh -c command args..."
15 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
16 - Added shell environment variable substitution
17 - Added the "read" shell builtin.
18 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
19 used to create an infinite loop: ls, cursor up, left, down.
20 * Added support for being a login shell, so things like
21 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
22 invoke the shell. Now you can use BusyBox as a login shell.
23 * ls.c now ignores '-g', since some ftp clients like that sort
24 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
25 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
26 it always sets the controlling terminal before running any programs
27 * Fix to tr so it recognizes standard escape sequences. Merged common
28 escape seq. code from tr and echo into utility.c. Fix thanks to
29 Matt Kraai <kraai@alumni.carnegiemellon.edu>.
35 * Now compiles vs libc5 (which can save lots of space for
37 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
38 help messages (i.e --help). Saves 17k over a full compile.
39 * Added cut and tr from minix, since due to the license change,
40 we can now use minix code. Minix tr saves 4k.
41 * insmod now works. It costs 29k, but imagine an initrd with a
42 staticly linked busybox containing only insmod and sh, a few /dev
43 entries, and a kernel module or two... It doesn't get smaller
44 then this folks (I pity the fool that writes insmod in asm ;-).
45 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
46 * Added a mini ar archive utility, especially written for BusyBox by
47 Glenn McGrath <bug1@netconnect.com.au>
48 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
49 * Added setkeycodes, for those that have wierd keyboard buttons.
50 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
51 <ams@trillian.itslinux.org> for contributing these.
52 * Added 'grep -v' option (inverted search) and updated
53 docs accordingly. -beppu
55 * Replaced the telnet implementation with one written by
56 Tomi Ollila <too@iki.fi> It works great and costs 3k.
57 * BusyBox sh (lash) now supports being used as a standalone shell. When
58 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
59 be invoked as shell internals. Best used when compiling staticly
61 * BusyBox sh (lash) internals now behave as expected wrt pipes
63 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
64 * Fixed update segfault
65 * Fixed mknod -- minor number was always 0
66 * Fixed tar option parsing, so both "tar xvf foo.tar" and
67 "tar -xvf foo.tar" now work (i.e. no "-" before options)
68 (this was very broken in 0.43).
69 * Several contributions from Randolph Chung <tausq@debian.org>.
70 * cp/mv now accepts the -f flag
71 * tail can now accept -<num> commands (e.g. -10) for better
72 compatibility with the standard tail command
73 * added a simple id implementation; doesn't support sup. groups yet
74 * logname used getlogin(3) which uses utmp. Now it doesn't.
75 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
76 * Add support for "noatime" and "nodiratime" mount flags to mount.
77 * Changed 'umount -f' to mean force, and actually use umount2.
78 * Changed 'umount -l' to mean "Do not free loop device".
79 * Fixed basename to support stripping of suffixes. Patch thanks
80 to xiong jianxin <jxiong@uiuc.edu>
81 * cp -fa now works as expected for symlinks (it didn't before)
82 * zcat now works (wasn't working since option parsing was broken)
83 * Renamed "mnc" to the more correct "nc" (for netcat).
84 * Makefile intelligence updates
85 * Changed the way init parses /etc/inittab entries to avoid problems
86 with commands that contain colons in them. Fix thanks to
87 Pavel Roskin <proski@gnu.org>
88 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
89 Fix thanks to Pavel Roskin <proski@gnu.org>
90 * Made "killall" complain (not error and exit) about processes that it
91 cannot find by name -- Pavel Roskin <proski@gnu.org>
92 * Fixed more and ps to have sensible terminal width defaults, thanks
94 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
95 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
96 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
97 * Fixed segfault caused by "touch -c"
98 * Fixed segfault caused by "rm -f"
99 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
100 and "--" support from Pavel Roskin.
101 * Fixed segfault caused by "cp -a -a" and similar abuses.
102 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
103 * "which" rewritten to use stat(). Fixes to improve its compatability
104 with traditional implementations -- Pavel Roskin.
105 * "mount" now reports errors from nfsmount() and assumes NFS mount
106 if ':' is present in the device name - Pavel Roskin
107 * Fixed exit status for killall - Pavel Roskin
108 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
109 * Fixed 'mount -a' so it works as expected.
110 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
111 * Implemented "ping -s", fixed error messages and argument parsing -
113 * Syslogd will not go to background if "-n" is given. Better help
114 and argument checking -- Pavel Roskin
115 * Fixed a small bug that could cause tar to emit warning messages
116 and not extract the first file in a directory in some cases
117 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
118 for helping track this one down.
120 * Fixed grep "Line too long" problem -- John Beppu
121 * Fixed 'grep -q -i B some_file' so it works
122 * math takes input from stdin if no args are given. -- John Beppu
123 * math was renamed to dc. Although it deviates from dc's behaviour,
124 this will probably be remedied in the future. -- John Beppu
127 -Erik Andersen, June 21, 2000
131 Previously, an erronous announcement of BusyBox 0.44 was made, so to
132 avoid possible confusion, we are skipping straight to 0.45, and calling
139 * Major update to the provided documentation.
140 * Busybox now includes a shell! It currently costs 7.5 k (plus an
141 additional 2.5 k if you compile in command line editing). Handles
142 job control, has the usual set of builtins, and does everything
143 except for handling programming statements (if, while, etc...)
144 * Busybox can now work perfectly when /proc is disabled, thereby
145 saving a bunch of memory (kernel /proc support is not thin). This
146 is done by making use of some nice kernel patches I wrote up to
147 support the features that busybox requires and that /proc usually
148 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
149 patch your kernel with the devps patch in the kernel-patches/
151 * Wrote basename, dirname, killall, and uptime.
152 * tar has been completely rewritten by me. Both tar creation and
153 extraction are now well behaved. Costs 7.6k with all optional
154 tar features enabled, and 5k for just tar extraction support.
155 * Added freeramdisk, which will free up all memory associated
156 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
157 and then adjusted a bit by me.
158 * Added tr from John Lombardo <john@deltanet.com>
159 * Added echo and test (from me).
160 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
161 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
162 * Several fixes from Pavel Roskin <proski@gnu.org>:
163 - When `tail' fails to open a file it now exits.
164 - When `syslogd' is given the `-n' option it should still use
165 fork() for running klogd.
166 * nslookup types are now changed to u_int32_t (instead of uint32_t)
167 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
168 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
169 to count hard-linked files more then once). Many thanks to
170 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
171 * Removed /proc dependancies for init and free (while maintaining
172 exactly the same functionality). /proc takes up 90k of kernel
173 space, so it is nice to avoid using it at all costs.
174 * init no longer tries to mount /proc (unless there is less the 1 meg
175 free). Use of /proc (or not) is policy that should be set up in
176 /etc/fstab (or in hardcoded scripts), not in init.
177 * Fixed rebooting when init runs as an initrd.
178 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
179 - update.c rewritten to look more like update-2.11
180 - moveed the inode hash out of du.c and into utility.c to make
181 it a common resource that can be used by other apps.
182 - cp_mv.c now checks inodes to see if a source and dest are
183 the same, and prints an error (instead of endlessly looping).
184 - mv now attempts to do a rename, and will fall back to doing
185 a copy only if the rename fails.
186 - Syslogd now supports multiple concurrent connections
187 * Several fixes from Pavel Roskin <proski@gnu.org>:
188 - Fixes to sort. Removed "-g", fixed and added "-r"
189 - Fixes to the makefile for handling "strip"
190 * An initial telnet implementation was added by
191 Randolph Chung <tausq@debian.org>.
192 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
193 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
194 to match the terminal (defaults to width=79 when this is off).
195 * ps now accepts (and ignores) all options except for "--help" (which
196 as would be expected displays help).
197 * Fixed mount'ing loop devices when the filesystem type was not
198 specified. It used to revert to non-loop after the first try.
199 * all mallocs now use xmalloc (and so are OOM error safe), and
200 the common error handling saves a few bytes. Thanks to
201 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
202 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
203 * Fix symlink following bug in chmod -R and friends.
204 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
205 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
214 * Fairly massive restructuring of umount.c to deal with remounting
215 busy devices read-only. Adds a -r option to control that; it is
216 optionally compiled in with BB_FEATURE_REMOUNT
217 * Added a bunch of functions to mtab.c to interact with the
218 {get,set,end}mntent interface; as it turns out, those functions do
219 not appear to be re-entrant, and that causes a lot of problems with
220 the way umount was originally written.
221 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
222 to be more consistent with sysvinit
223 * Changes to init.c to use the new -r option to umount. Also increased
224 the sleep time between the time the TERM and KILL signals are sent
229 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
230 extensively rewritten from the original cp.c.
231 * Fixed cp and mv so if the source and destination are a the
232 same directory it will print an error and continue.
233 * Also added a warning message to the `mv' usage string saying that
234 this is not GNU mv, and it will break hard links. cp also breaks
236 * ln.c: implemented `-n' switch, no-deref symlinks.
237 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
238 * name buffer overrun guards to prevent future crashes.
239 - Always check exit status.
240 - Purge all use of `creat()', replace with `open()'.
242 - recursiveAction was overriding the value of followLinks thus
244 - isDirectory now takes a followLinks boolean, updated all callers
245 - copyFile had the followLinks logic reversed.
246 * messages.c: New file. Put common error message strings all in
247 one place in an attempt to shrink the binary a little.
252 * changed fsck_minix.c to reduce its .bss size significantly
254 * Made tar creation support in busybox tar optional. You no longer
255 * _have_ to put a "-" in front of tar options. Tar could inadvertently
256 * change permissions and ownership on
257 certain directories pointed to by symlinks.
258 * Made grep and grep -h do the right thing wrt printing
259 the file name (it failed to print files names in many cases).
260 * Fix a namespace aliasing problem wereby if du was built in, the
261 symlink for both du and dutmp would be installed, or then rm was
262 built in, the symlinks for both rm and rmmod would be installed.
263 * Added a closelog() to init.c after loging -- fix thanks to
264 Taketoshi Sano <kgh12351@nifty.ne.jp>
265 * Rewrote and simplified logger. Added the "-t" option, and made it
266 behave itself a bit better.
267 * Optional support contributed by Ben Collins <bcollins@debian.org>
268 for the kernel init chroot patch by Werner Almesberger, which
269 allows init to chroot to a new device, and umount the old one.
270 * Fixed bug that wouldn't let one chown a symlink -- it would
271 always dereference before. -beppu
272 * Fixed a bug where init could have reference already freed memory.
273 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
274 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
275 * Added (and documented) "-n" option for head
276 * Cleanup for a number of usage messages -- also
277 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
278 * Cosmetic fix to busybox.c (Don't print a comma at the
279 end of line if there are no more application names).
280 * Fixed a stupid bug in "head" option handling ("head -n"
282 * Moved commonly used functions "xmalloc()" and "exit()"
283 to utility.c (with proper #ifdef's).
284 * Created a tiny tail implementation, removing -c, -q, -v, and making
285 tail -f work only with a single file. This reduced tail from 6k to
286 2.4k. The bigger/more featured tail can still be had by disabling
287 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
288 * Ping now falls back to doing the right thing if /etc/protocols
290 * Fixed mount and umount. Previously they could leak loop device
291 allocations, causing the system to quickly run out. Fix for umount
292 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
293 * ls formatting on eight charactor user names fixed by
294 Randolph Chung <tausq@debian.org>.
295 * cp could, when copying symlinks, change permissions of the
296 files pointed to by the symlinks.
297 * Several fixes from Pavel Roskin <proski@gnu.org>:
298 - `chown' with 1 argument displayed the error incorrectly
299 - `fdflush', `length' and `printf' crashed if run without arguments
300 - `fdflush' tried to flush itself using *argv
301 - added "skip" and "seek" to dd.
302 - ls no longer messus up output when combining files and
303 directories on the command line
304 * swapoff -a was not working. Now it is.
305 * init did not cleanly unmount filesystems on reboot. Now it does.
306 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
308 * Some architectures (PowerPc) assume chars are unsigned, so they could
309 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
310 * Began converting error handling to use some common routines
312 * syslogd now has better message handling and ignores SIGHUP.
313 * install.sh had a bug preventing installation to the specified
314 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
315 * You can now spefify alternative strip commands -- change
316 also from Gilbert Coville.
322 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
323 by Edward Betts <edward@debian.org>
324 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
325 type commands (file in a directory to another directory) from
327 * Fixed a logger bug that caused garbage to be written to the syslog
328 (unless you used busybox syslog, which hid the bug). Thanks to
329 Alex Holden <alex@linuxhacker.org> for the fix.
330 * /bin/true and /bin/false were echoing a blank line when run.
332 * mkdir -p would print an error when asked to mkdir an existing dir
333 with no interveining subdirectories.
334 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
335 * and support in umount for loop
336 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
337 <bcollins@debian.org>
338 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
339 * fullWrite() not only if BB_TAR is defined, but also
340 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
341 * add some compiler optimizations to further reduce executable size
342 (as a side note, on my machines the largest code is generated
343 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
345 * Compile now won't fail if busybox.def.h defines
346 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
347 referenced, but not compiled)
348 * Fixed a bug in setting TERM for serial console support. TERM now
349 defaults to "ansi" for serial consoles.
350 * Fixed a bug in handling the CONSOLE env. variable for serial
353 -Erik Andersen, Jan 15, 2000
356 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
357 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
358 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
359 for loading application character maps for Unicode fonts.
360 * Major init re-work. init now supports inittab (slightly different
361 but similar to sysvinit), allowing me to get all the policy out of
362 init and into the conf file. It works just fine without inittab
363 being present, but if you dont like the defautl behavior you can
364 now do something about it. Init is much cleaner as a result.
365 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
366 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
367 * failure of 'logger -p'. -erik Added the -s option to du -beppu
368 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
369 with the 2.0.x Linux kernel.
370 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
372 * Grep -i previously failed on UPPER CASE patterns due to a silly
373 regexp implementation bug that is now fixed.
374 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
375 * Fixed a bug where tar would not set the user and group on device
377 * Fixed a bug where tar would not restore the time to files. Fixed a
378 * major security problem with tar -- it changed ownership
379 of any file pointed to by a symlink to 777 (like say libc....)
381 * cp and mv were very broken when moving directories. I have rewritten
382 them so they should now work as expected.
383 * sed now supports addresses (numeric or regexp, with negation) and
384 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
385 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
386 * Some cosmetic fixes to ls output formatting to make it behave more
388 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
389 * <fwv@myrtle.lahn.de>:
390 - Added gunzip -t, removed gunzip.c dead code,
391 - fixed several typos
392 - Glibc 2.0.7 and libc5 compile fixes
393 * Fixed a bug where 'mknod --help' would segfault.
396 -Erik Andersen, Jan 07, 2000
399 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
400 <tausq@debian.org>. 3 items off the TODO list!
401 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
402 * tail from GNU textutils-1.19, but adjusted
403 to suit my evil purposes. Costs 6k. I'll make it smaller
405 * on reboot, init called 'umount -a -n', which caused errors
406 when BB_MTAB was not enabled. Changed to 'umount -a', which does
408 * init will now try to run /sbin/getty if it is present (for easy
409 integration with the about-to-be-released tinylogin.)
410 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
411 * -l' was failing on long directories, since my_getid was leaking
412 one file descriptor per file. Oops.
413 * Fixed rebooting from init. I'd accidently left some debugging code
415 which blocked reboots.
416 * Fixed reboot, halt (and added poweroff) such that they handle it when
417 init is not at PID 1 (like when running in an initrd).
418 * Added a prelinary du implementation. Some parameter parsing
419 stuff still needs to be added. -beppu (John Beppu
421 * Implemented tee. -beppu Implemented head. -beppu
423 -Erik Andersen, Dec 10, 1999
426 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
428 * df will not exit on error, but will stat all mounted filesystems.
429 * Fixed tar so uid/gid/permissions on extracted tarballs will be
431 * Fixed find -name so it properly uses shell wildcard patterns
432 (i.e. `*', `?', and `[]') instead of regular expressions, which
433 was causing some confusing and unexpected behavior.
434 * Added klogd to syslogd, so now the log will contain both system and
436 * syslogd now creates the /dev/log socket to make sure it is there, and
437 is actually a socket with the right permissions.
438 * I've taken a first step to making busybox not need the /proc
439 filesystem. Most apps don't need it. Those that _require_ it,
440 will complain if you enable them when you disable
441 BB_FEATURE_USE_PROCFS.
443 -Erik Andersen, Dec 5, 1999
446 * Wrote a micro syslogd, and a logger util (to log things to the syslog
447 from the command line or scripts) With both compiled in, costs 4k.
448 * Fixed 'make install' so symlinks are installed in their proper
449 * locations. Changed the build system slightly so that features can
451 or disabled from the busybox.defs.h header file, without trying to
452 compile in a source file named after that featue (unless that file
454 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
455 * -r' both work. dd now properly handles input beyond 1 block from
456 * stdin. Fixed a bug where tar unpacked everything a directories.
458 from createPath into mkdir where it belonged, thereby making tar
460 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
462 last file in the list.
463 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
465 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
466 are presented properly.
470 -Erik Andersen, Nov 25, 1999
473 * fixed dd so it properly defaults to stdin and stdout when no
474 if= and of= are set (fix thanks to Eric Delaunay).
475 * Don't try to close the file descriptor of a pipein tar. (fix also
478 * Made createPath be quiet (again thanks to Eric Delaunay). If
479 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
480 command you define it as will be run if the init script exits.
481 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
482 * NFS support added to mount by Eric Delaunay. It costs 10k when
484 in, but that is still a big win for those that use NFS.
485 * Made 'rm -f' be silent for non-existant files (thanks to Eric
486 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
488 and acts as god intended gunzip and zcat to act. They answer
489 --help and obey the '-c' flag.
490 * Fixed a bug in mv which caused it to not move files when the
493 * Fixed a decimal-instead-of-octal bug causing mkdir to make
495 with very wrong permissions.
496 * chmod would overwrite file permissions instead of modifying them.
497 Now it properly modifies permissions.
498 * Init now sends warnings destined for the console to /dev/console to
500 they show up on whatever the active console it. Otherwise
501 important messages (for example that the system is rebooting) were
502 not seen when switched to a different VT.
504 -Erik Andersen, Nov 17, 1999
507 * gzip now obeys the principle of least surprise and acts like god
509 (i.e. it accepts a file name, answers --help, and obeys the '-c'
510 flag and only then outputs to stdout).
511 * Fixed more.c to compile autowidth on sparc and set initial winsize
512 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
514 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
515 * tar now accepts --help chmod, chown, and chgrp usage now works
516 * General usage (i.e. --help) cleanups for most apps umount now parses
517 * options correctly tar can now unpack tarballs containing device
519 sockets, and fifos (though it can't pack them up) thanks to Matt
520 Porter. Creating archives containing these is still left to the
522 * fixed up the license in more.c to properly point to Bruce Perens.
524 -Erik Andersen, Nov 11, 1999
527 * ls -l now displays link names outside the current directory,
528 Patch thanks to Eric Delaunay
529 * init now properly handles sparc serial consoles and does a
530 better job of finding the real console device rather than using
531 /dev/console which doesn't support job control. Patch also thanks
533 * more started to read from stdin after the last file was finished, and
534 options were not parsed correctly (fix thanks to Eric Delaunay).
535 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
536 * rm wouldn't remove a symlink unless the symlink was valid. This was
537 a side effect of the busybox 0.32 recursiveAction() fix. Things
538 should now work correctly.
539 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
540 * it does. sed was appending a \n to the end of lines with
542 Now it doesn't do that.
543 * ls -l now bypasses libc6 nss when displaying user/group names.
544 Now uses my_getpwuid and my_getgrgid.
546 -Erik Andersen, Nov 8, 1999
549 * Fixed a bug where init could hang instead of rebooting.
550 * Removed some debugging noise from init.c
551 * Fixed ln so it works now (it was very broken).
552 * Fixed df so it won't segfault when there is no /etc/fstab,
553 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
554 is not installed (since they cannot fixup "/dev/root" to
555 state the real root device name)
556 * merged some redundant code from mtab.c/df.c into utility.c
558 -Erik Andersen, Nov 5, 1999
561 * More changes -- many thanks to Lineo for paying me to work on
562 busybox. If you have any problems please let me know ASAP at
563 andersen@lineo.com or andersee@debian.org
564 * usage() now prints the BusyBox version. This will help folks
565 realize that they are not in Kansas anymore.
566 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
567 * arguments. Now it doesn't do that. kill wasn't properly accepting
568 * signal names. It does now. Added new apps chvt and deallocvt (I
569 * should probably add open) Major rewrite of init.c. Code is now
570 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
571 * with full regular expressions!). Fixed a stupid seg-fault in sync
572 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
573 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
574 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
575 * cost of ~1.5k and the need for a rw /etc)
576 folks to use a real /etc/mtab file instead of a symlink to
577 /proc/mounts. mount, and umount will add/remove entries and df
578 will now use /etc/mtab if BB_MTAB is defined.
579 * Fixed a nice bug in recursiveAction() which caused it to infinitely
580 hunt through /proc/../fd/* creating new file descriptors if it
581 followed the /dev/fd link over to /proc. recursiveAction() now
582 lstat's the file when followLinks==FALSE so it won't follow links
583 as the name suggests. Fix thanks to Matt Porter
587 -Erik Andersen, Nov 4, 1999
590 * I added a changelog for version 0.30. adjusted find internals to
591 * make it smaller, and removed
593 * Fixed a segfault in ps when /etc/passwd or /etc/group
594 are absent. Now will warn you and carry on.
595 * Added in optional _real_ regular expression support (to be
596 the basis for a future sed utility). When compiled in it adds
597 3.9k, but makes grep much more capable.
598 * Checked out using nftw(3) for recursive stuff, but unfortunatly
599 it wasn't supported before GNU libc 2.1, and some folks use glibc
600 2.0.7 since it is much smaller than that latest and greatest.
602 -Erik Andersen, Oct 21, 1999
605 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
606 paying me to make these updates. If you have any problems with busybox,
607 or notice any bugs -- please let me know so I can fix it. These
611 * busybox can now invoke apps in two ways: via symlinks to the
612 busybox binary, and as 'busybox [function] [arguments]...'
613 * When invoked as busybox, the list of currently compiled in
614 functions is printed out (no this is not bloat -- the list has
615 to be there anyway to map invocation name to function).
616 * busybox no longer parses command lines for apps or displays their
617 usage info. Each app gets to handle (or not handle) this for
619 * Eliminated monadic, dyadic, descend, block_device, and
620 postprocess. It was cumbersome to have so many programs
621 cobbled together in this way. Without them, the app is much
623 * All shared code now lives in utility.c, and is properly
624 ifdef'ed to be only included for those apps requiring it.
625 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
626 so now each app has the function prototype of (da-dum): extern
627 int foo_main(int argc, char** argv); which speeds integration
629 * Adjusted the Makefile to make it easier to
630 {en|dis}able debugging.
631 * Changed default compiler optimization to -Os
632 (optimize for smaller binaries).
635 * To cope with the new app function prototype and the removal of
636 monadic, dyadic, etc, the following apps were re-written:
637 * cat - Works same as always. chgrp, chmod, chown -
638 * rewrite. Combined into a single
639 source file. Absorbed patches from Enrique Zanardi
640 <ezanard@debian.org> that removes the dependency on
641 libc6 libnss* libraries.
642 * cp - Can now do 'cp -a' can can copy devices,
643 pipes, symlinks, as well as recursive or non-recursive
645 * fdflush - adjusted to remove dependancy on struct
646 * FileInfo. find - Now includes some basic regexp matching
647 which will be the basic of a future mini-sed.
648 * ln - Same functionality. mkdir - Added -p flag to
649 * feature set. mv - rewrite. rm - Added -f flag to
650 * feature set. rmdir - Same functionality. swapon,
651 * swapoff - Combined into a single binary. No longer
652 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
654 * touch - Same functionality. date - adjusted with a patch
655 * from Matthew Grant <grantma@anathoth.gen.nz>
656 to accomodate glibc timezone support. I then ripped out GNU
658 * mkswap -- new version merged from util-linux. Can now make
660 * Replaced the old and star, unstar, and tarcat with the tar
661 implementation from sash. Now tar behaves as god intended it
662 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
663 * dd -- rewritten. Can with with files, stdin, stdout. Added the
664 * following new apps: loadfont -- added from debian boot floppies
665 * chroot -- added based on a patch from Paolo Molaro
666 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
667 * simple strings ps -- I just wrote it. Has _no_ options at all,
668 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
670 internationalization and such to make them smaller.
671 * sfdisk -- Added from util-linux (minus
672 * internationalization and such). Probably some other
673 * changes that I forgot to document...
675 -Erik Andersen, Oct 20, 1999
678 This version was a messy pre-alpha. stay away or it will bite you.
679 -Erik Andersen, Sep 24, 1999
682 mini-netcat (mnc) rewritten.
685 Mount now supports -a, and -t auto.
686 Mount now updates mtab correctly for 'ro'.
687 More checks screen rows size, outputs bytes percentage.
688 Printf added as module.
690 Touch now creates files. -c option for no create.
