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