2 * Made tar creation support in busybox tar optional.
3 * You no longer _have_ to put a "-" in front of tar options.
4 * Tar could inadvertently change permissions and ownership on
5 certain directories pointed to by symlinks.
6 * Made grep and grep -h do the right thing wrt printing
7 the file name (it failed to print files names in many cases).
8 * Fix a namespace aliasing problem wereby if du was built in, the
9 symlink for both du and dutmp would be installed, or then rm was
10 built in, the symlinks for both rm and rmmod would be installed.
11 * Added a closelog() to init.c after loging -- fix thanks to
12 Taketoshi Sano <kgh12351@nifty.ne.jp>
13 * Rewrote and simplified logger. Added the "-t" option, and made it
14 behave itself a bit better.
15 * Optional support contributed by Ben Collins <bcollins@debian.org>
16 for the kernel init chroot patch by Werner Almesberger, which
17 allows init to chroot to a new device, and umount the old one.
18 * added (and documented) "-n" option for head -
19 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
20 * Cleanup for a number of usage messages -- also
21 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
22 * Fixed bug that wouldn't let one chown a symlink -- it would
23 always dereference before. -beppu
29 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
30 by Edward Betts <edward@debian.org>
31 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
32 type commands (file in a directory to another directory)
34 * Fixed a logger bug that caused garbage to be written to the syslog
35 (unless you used busybox syslog, which hid the bug). Thanks
36 to Alex Holden <alex@linuxhacker.org> for the fix.
37 * /bin/true and /bin/false were echoing a blank line when run. Now fixed.
38 * mkdir -p would print an error when asked to mkdir an existing dir
39 with no interveining subdirectories.
40 * Fixed "syslogd -O" so that it works.
41 * Added -o loop option for mount, and support in umount for loop
42 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
44 * Several fixes from Marco Pantaleoni <panta@prosa.it>
45 * compile in fullWrite() not only if BB_TAR is defined, but also
46 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
47 * add some compiler optimizations to further reduce executable size
48 (as a side note, on my machines the largest code is generated by
49 gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with -O2
51 * Compile no longer fails if busybox.def.h defines BB_FEATURE_LINUXRC
52 but not BB_INIT. (init_main used to be referenced, but not compiled)
53 * Fixed a bug in setting TERM for serial console support. TERM now
54 defaults to "ansi" for serial consoles.
55 * Fixed a bug in handling the CONSOLE env. variable for serial consoles.
57 -Erik Andersen, Jan 15, 2000
60 * New Apps: sort, uniq. -beppu
61 * New Apps: lsmod, rmmod -erik
62 * New Apps: fbset contributed by Randolph Chung <tausq@debian.org>.
63 * New App:: loadacm contributed by Peter Novodvorsky <petya@logic.ru>
64 for loading application character maps for Unicode fonts.
65 * Major init re-work. init now supports inittab (slightly different
66 but similar to sysvinit), allowing me to get all the policy out
67 of init and into the conf file. It works just fine without inittab
68 being present, but if you dont like the defautl behavior you can
69 now do something about it. Init is much cleaner as a result.
70 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
71 * Fixed an embarrasing segfault in head -beppu
72 * Fixed the embarrasing failure of 'logger -p'. -erik
73 * Added the -s option to du -beppu
74 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
75 with the 2.0.x Linux kernel.
76 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
78 * Grep -i previously failed on UPPER CASE patterns due to a silly
79 regexp implementation bug that is now fixed.
80 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
81 * Fixed a bug where tar would not set the user and group on device
83 * Fixed a bug where tar would not restore the time to files.
84 * Fixed a major security problem with tar -- it changed ownership
85 of any file pointed to by a symlink to 777 (like say libc....)
87 * cp and mv were very broken when moving directories. I have rewritten
88 them so they should now work as expected.
89 * sed now supports addresses (numeric or regexp, with negation) and
90 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
91 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
92 * Some cosmetic fixes to ls output formatting to make it behave more
94 * Fixed a stupid segfault in kill.
95 * Several fixes from Friedrich Vedder <fwv@myrtle.lahn.de>:
96 - Added gunzip -t, removed gunzip.c dead code,
98 - Glibc 2.0.7 and libc5 compile fixes
99 * Fixed a bug where 'mknod --help' would segfault.
102 -Erik Andersen, Jan 07, 2000
105 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
106 <tausq@debian.org>. 3 items off the TODO list!
107 * I wrote free (just calls "cat /proc/meminfo").
108 * Added tail, based on tail from GNU textutils-1.19, but adjusted
109 to suit my evil purposes. Costs 6k. I'll make it smaller sometime.
110 * on reboot, init called 'umount -a -n', which caused errors
111 when BB_MTAB was not enabled. Changed to 'umount -a',
112 which does the right thing.
113 * init will now try to run /sbin/getty if it is present (for easy
114 integration with the about-to-be-released tinylogin.)
115 * kill now behaves itself properly, added 'kill -l' to list signals
116 * 'ls -l' was failing on long directories, since my_getid was leaking
117 one file descriptor per file. Oops.
118 * Fixed rebooting from init. I'd accidently left some debugging code in
119 which blocked reboots.
120 * Fixed reboot, halt (and added poweroff) such that they handle it when
121 init is not at PID 1 (like when running in an initrd).
122 * Added a prelinary du implementation. Some parameter parsing
123 stuff still needs to be added. -beppu (John Beppu <beppu@lineo.com>)
124 * Implemented tee. -beppu
125 * Implemented head. -beppu
127 -Erik Andersen, Dec 10, 1999
130 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
132 * df will not exit on error, but will stat all mounted filesystems.
133 * Fixed tar so uid/gid/permissions on extracted tarballs will be correct.
134 * Fixed find -name so it properly uses shell wildcard patterns
135 (i.e. `*', `?', and `[]') instead of regular expressions, which
136 was causing some confusing and unexpected behavior.
137 * Added klogd to syslogd, so now the log will contain both system and
139 * syslogd now creates the /dev/log socket to make sure it is there, and
140 is actually a socket with the right permissions.
141 * I've taken a first step to making busybox not need the /proc
142 filesystem. Most apps don't need it. Those that _require_ it,
143 will complain if you enable them when you disable
144 BB_FEATURE_USE_PROCFS.
146 -Erik Andersen, Dec 5, 1999
149 * Wrote a micro syslogd, and a logger util (to log things to the syslog
150 from the command line or scripts) With both compiled in, costs 4k.
151 * Fixed 'make install' so symlinks are installed in their proper locations.
152 * Changed the build system slightly so that features can now be enabled
153 or disabled from the busybox.defs.h header file, without trying to
154 compile in a source file named after that featue (unless that file exists).
155 * Several options are now moved into busybox.defs.h
156 * Now 'rm -R' and 'rm -r' both work.
157 * dd now properly handles input beyond 1 block from stdin.
158 * Fixed a bug where tar unpacked everything a directories. Moved some code
159 from createPath into mkdir where it belonged, thereby making tar work properly.
160 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat out the
161 last file in the list.
162 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed 'ls -l'
163 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid are
168 -Erik Andersen, Nov 25, 1999
171 * fixed dd so it properly defaults to stdin and stdout when no
172 if= and of= are set (fix thanks to Eric Delaunay).
173 * Don't try to close the file descriptor of a pipein tar. (fix also from
175 * Made createPath be quiet (again thanks to Eric Delaunay).
176 * If BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
177 command you define it as will be run if the init script exits.
178 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
179 * NFS support added to mount by Eric Delaunay. It costs 10k when compiled
180 in, but that is still a big win for those that use NFS.
181 * Made 'rm -f' be silent for non-existant files (thanks to Eric Delaunay).
182 * changed zcat.c to gunzip.c. It now obeys the principle of least surprise
183 and acts as god intended gunzip and zcat to act. They answer --help and
185 * Fixed a bug in mv which caused it to not move files when the destination
187 * Fixed a decimal-instead-of-octal bug causing mkdir to make directories
188 with very wrong permissions.
189 * chmod would overwrite file permissions instead of modifying them.
190 Now it properly modifies permissions.
191 * Init now sends warnings destined for the console to /dev/console to ensure
192 they show up on whatever the active console it. Otherwise important
193 messages (for example that the system is rebooting) were not seen when
194 switched to a different VT.
196 -Erik Andersen, Nov 17, 1999
199 * gzip now obeys the principle of least surprise and acts like god intended
200 (i.e. it accepts a file name, answers --help, and obeys the '-c' flag
201 and only then outputs to stdout).
202 * Fixed more.c to compile autowidth on sparc and set initial winsize
203 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric Delaunay.
204 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
205 * tar now accepts --help
206 * chmod, chown, and chgrp usage now works
207 * General usage (i.e. --help) cleanups for most apps
208 * umount now parses options correctly
209 * tar can now unpack tarballs containing device special files,
210 sockets, and fifos (though it can't pack them up) thanks
211 to Matt Porter. Creating archives containing these is still
212 left to the interested student.
213 * fixed up the license in more.c to properly point to Bruce Perens.
215 -Erik Andersen, Nov 11, 1999
218 * ls -l now displays link names outside the current directory,
219 Patch thanks to Eric Delaunay
220 * init now properly handles sparc serial consoles and does a
221 better job of finding the real console device rather than using
222 /dev/console which doesn't support job control. Patch also
223 thanks to Eric Delaunay.
224 * more started to read from stdin after the last file was finished, and
225 options were not parsed correctly (fix thanks to Eric Delaunay).
226 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
227 * rm wouldn't remove a symlink unless the symlink was valid. This was
228 a side effect of the busybox 0.32 recursiveAction() fix. Things
229 should now work correctly.
230 * grep wouldn't grep stdin. Now it does.
231 * sed wouldn't sed stdin. Now it does.
232 * sed was appending a \n to the end of lines with replacements.
233 Now it doesn't do that.
234 * ls -l now bypasses libc6 nss when displaying user/group names.
235 Now uses my_getpwuid and my_getgrgid.
237 -Erik Andersen, Nov 8, 1999
240 * Fixed a bug where init could hang instead of rebooting.
241 * Removed some debugging noise from init.c
242 * Fixed ln so it works now (it was very broken).
243 * Fixed df so it won't segfault when there is no /etc/fstab,
244 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
245 is not installed (since they cannot fixup "/dev/root" to
246 state the real root device name)
247 * merged some redundant code from mtab.c/df.c into utility.c
249 -Erik Andersen, Nov 5, 1999
252 * More changes -- many thanks to Lineo for paying me to work on
253 busybox. If you have any problems please let me know ASAP
254 at andersen@lineo.com or andersee@debian.org
255 * usage() now prints the BusyBox version. This will help folks
256 realize that they are not in Kansas anymore.
257 * Fixed mkdir -m option so that it works.
258 * kill segfaulted w/o any arguments. Now it doesn't do that.
259 * kill wasn't properly accepting signal names. It does now.
260 * Added new apps chvt and deallocvt (I should probably add open)
261 * Major rewrite of init.c. Code is now readable by mere mortals IMHO.
262 * Wrote sed -- weighs only 1.8k (5.8k with full regular expressions!).
263 * Fixed a stupid seg-fault in sync
264 * Fixed mount -- mount -a failed to parse and apply mount options
265 * Fixed umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
266 * umount -a no longer umounts /proc
267 * Added BB_MTAB, allowing (at the cost of ~1.5k and the need for a rw /etc)
268 folks to use a real /etc/mtab file instead of a symlink to /proc/mounts.
269 mount, and umount will add/remove entries and df will now use /etc/mtab
270 if BB_MTAB is defined.
271 * Fixed a nice bug in recursiveAction() which caused it to infinitely
272 hunt through /proc/../fd/* creating new file descriptors if it
273 followed the /dev/fd link over to /proc. recursiveAction() now
274 lstat's the file when followLinks==FALSE so it won't follow links
275 as the name suggests. Fix thanks to Matt Porter <porter@debian.org>.
278 -Erik Andersen, Nov 4, 1999
281 * I added a changelog for version 0.30.
282 * adjusted find internals to make it smaller, and removed
284 * Fixed a segfault in ps when /etc/passwd or /etc/group
285 are absent. Now will warn you and carry on.
286 * Added in optional _real_ regular expression support (to be
287 the basis for a future sed utility). When compiled in
288 it adds 3.9k, but makes grep much more capable.
289 * Checked out using nftw(3) for recursive stuff, but unfortunatly
290 it wasn't supported before GNU libc 2.1, and some folks use
291 glibc 2.0.7 since it is much smaller than that latest and greatest.
293 -Erik Andersen, Oct 21, 1999
296 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
297 paying me to make these updates. If you have any problems with busybox,
298 or notice any bugs -- please let me know so I can fix it. These
302 * busybox can now invoke apps in two ways: via symlinks to the
303 busybox binary, and as 'busybox [function] [arguments]...'
304 * When invoked as busybox, the list of currently compiled in
305 functions is printed out (no this is not bloat -- the list
306 has to be there anyway to map invocation name to function).
307 * busybox no longer parses command lines for apps or displays their
308 usage info. Each app gets to handle (or not handle) this for
310 * Eliminated monadic, dyadic, descend, block_device, and
311 postprocess. It was cumbersome to have so many programs
312 cobbled together in this way. Without them, the app is much
314 * All shared code now lives in utility.c, and is properly
315 ifdef'ed to be only included for those apps requiring it.
316 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
317 so now each app has the function prototype of (da-dum):
318 extern int foo_main(int argc, char** argv);
319 which speeds integration of new apps.
320 * Adjusted the Makefile to make it easier to
321 {en|dis}able debugging.
322 * Changed default compiler optimization to -Os
323 (optimize for smaller binaries).
326 * To cope with the new app function prototype and the removal of
327 monadic, dyadic, etc, the following apps were re-written:
328 * cat - Works same as always.
329 * chgrp, chmod, chown - rewrite. Combined into a single
330 source file. Absorbed patches from Enrique Zanardi <ezanard@debian.org>
331 that removes the dependency on libc6 libnss* libraries.
332 * cp - Can now do 'cp -a' can can copy devices,
333 pipes, symlinks, as well as recursive or non-recursive dir copies.
334 * fdflush - adjusted to remove dependancy on struct FileInfo.
335 * find - Now includes some basic regexp matching
336 which will be the basic of a future mini-sed.
337 * ln - Same functionality.
338 * mkdir - Added -p flag to feature set.
340 * rm - Added -f flag to feature set.
341 * rmdir - Same functionality.
342 * swapon, swapoff - Combined into a single binary. No longer
343 uses /etc/swaps. swap{on|off} -a uses /etc/fstab instead.
344 * touch - Same functionality.
345 * date - adjusted with a patch from Matthew Grant <grantma@anathoth.gen.nz>
346 to accomodate glibc timezone support. I then ripped out GNU getopt.
347 * mkswap -- new version merged from util-linux. Can now make >128Meg swaps.
348 * Replaced the old and star, unstar, and tarcat with the tar
349 implementation from sash. Now tar behaves as god intended
350 it to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
351 * dd -- rewritten. Can with with files, stdin, stdout.
352 * Added the following new apps:
353 * loadfont -- added from debian boot floppies
354 * chroot -- added based on a patch from Paolo Molaro <lupus@lettere.unipd.it>
355 * grep -- I just wrote it. Only matches simple strings
356 * ps -- I just wrote it. Has _no_ options at all, but works.
357 * fsck_minix, mkfs_minix -- added from util-linux, but I ripped out
358 internationalization and such to make them smaller.
359 * sfdisk -- Added from util-linux (minus internationalization and such).
360 * Probably some other changes that I forgot to document...
362 -Erik Andersen, Oct 20, 1999
365 This version was a messy pre-alpha. stay away or it will bite you.
366 -Erik Andersen, Sep 24, 1999
369 mini-netcat (mnc) rewritten.
372 Mount now supports -a, and -t auto.
373 Mount now updates mtab correctly for 'ro'.
374 More checks screen rows size, outputs bytes percentage.
375 Printf added as module.
377 Touch now creates files. -c option for no create.
