2 * New Apps: ping and hostname contributed by Randolph Chung
3 <tausq@debian.org>. 2 items off the TODO list!
4 * I wrote free (just calls "cat /proc/meminfo").
5 * Added tail, based on tail from GNU textutils-1.19, but adjusted
6 to suit my evil purposes. Costs 6k.
7 * on reboot, init called 'umount -a -n', which caused errors
8 when BB_MTAB was not enabled. Changed to 'umount -a',
9 which does the right thing.
10 * init will now try to run /sbin/getty if it is present (for easy
11 integration with the about-to-be-released tinylogin.)
12 * kill now behaves itself properly, added 'kill -l' to list signals
13 * 'ls -l' was failing on long directories, since my_getid was leaking
14 one file descriptor per file. Oops.
15 * Fixed rebooting from init. I'd accidently left some debugging code in
16 which blocked reboots.
17 * Fixed reboot, halt (and added poweroff) such that they handle it when
18 init is not at PID 1 (like when running in an initrd).
19 * Added a prelinary du implementation. Some parameter parsing
20 stuff still needs to be added. -beppu (John Beppu <beppu@lineo.com>)
21 * Implemented tee. -beppu
22 * Implemented head. -beppu
27 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
29 * df will not exit on error, but will stat all mounted filesystems.
30 * Fixed tar so uid/gid/permissions on extracted tarballs will be correct.
31 * Fixed find -name so it properly uses shell wildcard patterns
32 (i.e. `*', `?', and `[]') instead of regular expressions, which
33 was causing some confusing and unexpected behavior.
34 * Added klogd to syslogd, so now the log will contain both system and
36 * syslogd now creates the /dev/log socket to make sure it is there, and
37 is actually a socket with the right permissions.
38 * I've taken a first step to making busybox not need the /proc
39 filesystem. Most apps don't need it. Those that _require_ it,
40 will complain if you enable them when you disable
41 BB_FEATURE_USE_PROCFS.
43 -Erik Andrsen, Dec 5, 1999
46 * Wrote a micro syslogd, and a logger util (to log things to the syslog
47 from the command line or scripts) With both compiled in, costs 4k.
48 * Fixed 'make install' so symlinks are installed in their proper locations.
49 * Changed the build system slightly so that features can now be enabled
50 or disabled from the busybox.defs.h header file, without trying to
51 compile in a source file named after that featue (unless that file exists).
52 * Several options are now moved into busybox.defs.h
53 * Now 'rm -R' and 'rm -r' both work.
54 * dd now properly handles input beyond 1 block from stdin.
55 * Fixed a bug where tar unpacked everything a directories. Moved some code
56 from createPath into mkdir where it belonged, thereby making tar work properly.
57 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat out the
58 last file in the list.
59 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed 'ls -l'
60 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid are
65 -Erik Andrsen, Nov 25, 1999
68 * fixed dd so it properly defaults to stdin and stdout when no
69 if= and of= are set (fix thanks to Eric Delaunay).
70 * Don't try to close the file descriptor of a pipein tar. (fix also from
72 * Made createPath be quiet (again thanks to Eric Delaunay).
73 * If BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
74 command you define it as will be run if the init script exits.
75 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
76 * NFS support added to mount by Eric Delaunay. It costs 10k when compiled
77 in, but that is still a big win for those that use NFS.
78 * Made 'rm -f' be silent for non-existant files (thanks to Eric Delaunay).
79 * changed zcat.c to gunzip.c. It now obeys the principle of least surprise
80 and acts as god intended gunzip and zcat to act. They answer --help and
82 * Fixed a bug in mv which caused it to not move files when the destination
84 * Fixed a decimal-instead-of-octal bug causing mkdir to make directories
85 with very wrong permissions.
86 * chmod would overwrite file permissions instead of modifying them.
87 Now it properly modifies permissions.
88 * Init now sends warnings destined for the console to /dev/console to ensure
89 they show up on whatever the active console it. Otherwise important
90 messages (for example that the system is rebooting) were not seen when
91 switched to a different VT.
93 -Erik Andersen, Nov 17, 1999
96 * gzip now obeys the principle of least surprise and acts like god intended
97 (i.e. it accepts a file name, answers --help, and obeys the '-c' flag
98 and only then outputs to stdout).
99 * Fixed more.c to compile autowidth on sparc and set initial winsize
100 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric Delaunay.
101 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
102 * tar now accepts --help
103 * chmod, chown, and chgrp usage now works
104 * General usage (i.e. --help) cleanups for most apps
105 * umount now parses options correctly
106 * tar can now unpack tarballs containing device special files,
107 sockets, and fifos (though it can't pack them up) thanks
108 to Matt Porter. Creating archives containing these is still
109 left to the interested student.
110 * fixed up the license in more.c to properly point to Bruce Perens.
112 -Erik Andersen, Nov 11, 1999
115 * ls -l now displays link names outside the current directory,
116 Patch thanks to Eric Delaunay
117 * init now properly handles sparc serial consoles and does a
118 better job of finding the real console device rather than using
119 /dev/console which doesn't support job control. Patch also
120 thanks to Eric Delaunay.
121 * more started to read from stdin after the last file was finished, and
122 options were not parsed correctly (fix thanks to Eric Delaunay).
123 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
124 * rm wouldn't remove a symlink unless the symlink was valid. This was
125 a side effect of the busybox 0.32 recursiveAction() fix. Things
126 should now work correctly.
127 * grep wouldn't grep stdin. Now it does.
128 * sed wouldn't sed stdin. Now it does.
129 * sed was appending a \n to the end of lines with replacements.
130 Now it doesn't do that.
131 * ls -l now bypasses libc6 nss when displaying user/group names.
132 Now uses my_getpwuid and my_getgrgid.
134 -Erik Andersen, Nov 8, 1999
137 * Fixed a bug where init could hang instead of rebooting.
138 * Removed some debugging noise from init.c
139 * Fixed ln so it works now (it was very broken).
140 * Fixed df so it won't segfault when there is no /etc/fstab,
141 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
142 is not installed (since they cannot fixup "/dev/root" to
143 state the real root device name)
144 * merged some redundant code from mtab.c/df.c into utility.c
146 -Erik Andersen, Nov 5, 1999
149 * More changes -- many thanks to Lineo for paying me to work on
150 busybox. If you have any problems please let me know ASAP
151 at andersen@lineo.com or andersee@debian.org
152 * usage() now prints the BusyBox version. This will help folks
153 realize that they are not in Kansas anymore.
154 * Fixed mkdir -m option so that it works.
155 * kill segfaulted w/o any arguments. Now it doesn't do that.
156 * kill wasn't properly accepting signal names. It does now.
157 * Added new apps chvt and deallocvt (I should probably add open)
158 * Major rewrite of init.c. Code is now readable by mere mortals IMHO.
159 * Wrote sed -- weighs only 1.8k (5.8k with full regular expressions!).
160 * Fixed a stupid seg-fault in sync
161 * Fixed mount -- mount -a failed to parse and apply mount options
162 * Fixed umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
163 * umount -a no longer umounts /proc
164 * Added BB_MTAB, allowing (at the cost of ~1.5k and the need for a rw /etc)
165 folks to use a real /etc/mtab file instead of a symlink to /proc/mounts.
166 mount, and umount will add/remove entries and df will now use /etc/mtab
167 if BB_MTAB is defined.
168 * Fixed a nice bug in recursiveAction() which caused it to infinitely
169 hunt through /proc/../fd/* creating new file descriptors if it
170 followed the /dev/fd link over to /proc. recursiveAction() now
171 lstat's the file when followLinks==FALSE so it won't follow links
172 as the name suggests. Fix thanks to Matt Porter <porter@debian.org>.
175 -Erik Andersen, Nov 4, 1999
178 * I added a changelog for version 0.30.
179 * adjusted find internals to make it smaller, and removed
181 * Fixed a segfault in ps when /etc/passwd or /etc/group
182 are absent. Now will warn you and carry on.
183 * Added in optional _real_ regular expression support (to be
184 the basis for a future sed utility). When compiled in
185 it adds 3.9k, but makes grep much more capable.
186 * Checked out using nftw(3) for recursive stuff, but unfortunatly
187 it wasn't supported before GNU libc 2.1, and some folks use
188 glibc 2.0.7 since it is much smaller than that latest and greatest.
190 -Erik Andersen, Oct 21, 1999
193 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
194 paying me to make these updates. If you have any problems with busybox,
195 or notice any bugs -- please let me know so I can fix it. These
199 * busybox can now invoke apps in two ways: via symlinks to the
200 busybox binary, and as 'busybox [function] [arguments]...'
201 * When invoked as busybox, the list of currently compiled in
202 functions is printed out (no this is not bloat -- the list
203 has to be there anyway to map invocation name to function).
204 * busybox no longer parses command lines for apps or displays their
205 usage info. Each app gets to handle (or not handle) this for
207 * Eliminated monadic, dyadic, descend, block_device, and
208 postprocess. It was cumbersome to have so many programs
209 cobbled together in this way. Without them, the app is much
211 * All shared code now lives in utility.c, and is properly
212 ifdef'ed to be only included for those apps requiring it.
213 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
214 so now each app has the function prototype of (da-dum):
215 extern int foo_main(int argc, char** argv);
216 which speeds integration of new apps.
217 * Adjusted the Makefile to make it easier to
218 {en|dis}able debugging.
219 * Changed default compiler optimization to -Os
220 (optimize for smaller binaries).
223 * To cope with the new app function prototype and the removal of
224 monadic, dyadic, etc, the following apps were re-written:
225 * cat - Works same as always.
226 * chgrp, chmod, chown - rewrite. Combined into a single
227 source file. Absorbed patches from Enrique Zanardi <ezanard@debian.org>
228 that removes the dependency on libc6 libnss* libraries.
229 * cp - Can now do 'cp -a' can can copy devices,
230 pipes, symlinks, as well as recursive or non-recursive dir copies.
231 * fdflush - adjusted to remove dependancy on struct FileInfo.
232 * find - Now includes some basic regexp matching
233 which will be the basic of a future mini-sed.
234 * ln - Same functionality.
235 * mkdir - Added -p flag to feature set.
237 * rm - Added -f flag to feature set.
238 * rmdir - Same functionality.
239 * swapon, swapoff - Combined into a single binary. No longer
240 uses /etc/swaps. swap{on|off} -a uses /etc/fstab instead.
241 * touch - Same functionality.
242 * date - adjusted with a patch from Matthew Grant <grantma@anathoth.gen.nz>
243 to accomodate glibc timezone support. I then ripped out GNU getopt.
244 * mkswap -- new version merged from util-linux. Can now make >128Meg swaps.
245 * Replaced the old and star, unstar, and tarcat with the tar
246 implementation from sash. Now tar behaves as god intended
247 it to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
248 * dd -- rewritten. Can with with files, stdin, stdout.
249 * Added the following new apps:
250 * loadfont -- added from debian boot floppies
251 * chroot -- added based on a patch from Paolo Molaro <lupus@lettere.unipd.it>
252 * grep -- I just wrote it. Only matches simple strings
253 * ps -- I just wrote it. Has _no_ options at all, but works.
254 * fsck_minix, mkfs_minix -- added from util-linux, but I ripped out
255 internationalization and such to make them smaller.
256 * sfdisk -- Added from util-linux (minus internationalization and such).
257 * Probably some other changes that I forgot to document...
259 -Erik Andersen, Oct 20, 1999
262 This version was a messy pre-alpha. stay away or it will bite you.
263 -Erik Andersen, Sep 24, 1999
266 mini-netcat (mnc) rewritten.
269 Mount now supports -a, and -t auto.
270 Mount now updates mtab correctly for 'ro'.
271 More checks screen rows size, outputs bytes percentage.
272 Printf added as module.
274 Touch now creates files. -c option for no create.
