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