9 namely adduser, addgroup, deluser, delgroup, getty.
14 * Rodney Brown <RDBrown@mira.net>
15 -- Optimized gzip.c, shrinking it be ~1.5k
17 -Erik Andersen, --not yet released--
26 For this release I have bumped the version number to 0.60.0. This
27 reflects the fact that this release is intended to form a new stable
28 BusyBox release series. If you need to rely on a stable version of
29 BusyBox, you should plan on using the stable 0.60.x series. If bugs
30 show up then I will release 0.60.1, then 0.60.2, etc... This is also
31 intended to deal with the fact that the BusyBox build system will be
32 getting a major overhaul for the next release and I don't want that to
33 break products that people are shipping. To avoid that, the new build
34 system will be released as part of a new BusyBox development series
35 that will have some not-yet-decided-on odd version number. Once things
36 stabablize and the new build system is working for everyone, then I
37 will release that as a new stable release series.
41 -- Fixed wget output file opening (wget failed in 0.52).
42 -- Fixed a memory leak in syslogd (found by Adam Slattery).
43 * Vladimir Oleynik, Matt Kraai, Erik Andersen
44 -- several nasty bugs in ash and msh. msh could not assign
45 any variables and had debug code still enabled. ash
46 had several compile errors (depending on selected options)
47 and variable assignment problems as well.
50 * David McCullough <davidm@lineo.com> -- modprobe
51 * Vladimir Oleynik -- traceroute
52 * Erik Andersen -- pidof
55 * David Schleef, Erik Andersen, Stuart Hughes -- depmod.pl
56 This is a replacement for the depmod program from the modutils
57 package, but is fully cross platform and is designed to run on
58 your host system (not on the target).
62 -- fixed busybox.spec so it should now work on redhat systems
63 -- fixed dos2unix and unix2dos so they should work once again
64 -- Adjustments to make busybox more uClinux friendly. Busybox
65 should now work on uClinux systems without needing and source
66 code changes (applets that won't work on uClinux systems are
67 now automagicaly disabled).
68 -- various things (cleanups, libc compatibility work, etc, etc)
69 * Jim Gleason <jimg@lineo.com>
70 -- Fixed for sed, where it failed to preserve whether or not the
71 line was previously altered when running a subst command.
73 -- Made tar read 20 512byte blocks at a time (like GNU tar)
74 -- Allow msh.c assignments with the export and readonly commands.

89 -- Adjustments to make busybox more uClinux friendly
91 -- Fixed gzip so when a filename is '-' it will use stdin/stdout
92 -- dpkg rewrite. Should now be compatable with the real dpkg,
93 but needs more testing.
94 -- Updates to archiving tools (gunzip/gzip/cpio/ar/etc)
95 -- Rewrote uuencode, will allow base64 encoding to be used by wget
97 -- Fixed tr to support 'tr a-z A-Z' syntax,
98 -- Many ash corrections, optimizations, and cleanups.
99 -- optimizations for traceroute, md5sum, chown, ping
100 -- cmdedit updates and API change
101 -- Namespace cleanup (i.e. adding 'static' private function calls)
102 -- added "stopped jobs" warning to ash on exit
104 -- Fixed ping compile problem

124 only supports unpacking the ascii cpio format.
125 * Vladimir Oleynik and Erik Andersen -- added ash, the most correct
127 * Larry Doolittle -- hush, small shell designed specifically
128 for busybox. Quite usable but still a work in progress.

130 that only uses vfork, so it can be used on uClinux systems.
133 * Sterling Huxley -- Several bugfixes for the vi applet.
134 * Glenn McGrath -- Restructure unarchiving code to make more code
135 common to the ar, cpio, dpkg, dpkg-deb applets.

456 to Gyepi Sam <gyepi@praxis-sw.com>
457 * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>

463 * Add optional ls file sorting, thanks to a patch from
464 Sterling Huxley <sterling@europa.com>

475 -Erik Andersen, 25 September 2000
480 * Better portability. Now should compile cleanly with libc5,
481 GNU libc 2.0 and 2.1, and various Linux kernels including
482 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
483 to make /proc/mounts behave included in the kernel-patches dir).
484 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
485 local files that matched tarball contents!!! Fix thanks
486 to Marius Groeger <mgroeger@sysgo.de>
487 * Fixed a nasty bug in tar when could mess up saved symlinks.
488 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
489 thanks to Daniel Quinlan <quinlan@transmeta.com>
490 * Updates to handle Linux 2.4.0 kernels (kludged around the

493 * Fixed insmod module option parsing for options lacking an '='.
494 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>

502 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
503 used to create an infinite loop: ls, cursor up, left, down.
504 * Added support for being a login shell, so things like
505 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
506 invoke the shell. Now you can use BusyBox as a login shell.
507 * ls.c now ignores '-g', since some ftp clients like that sort
508 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
509 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
510 it always sets the controlling terminal before running any programs
511 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
512 - Fixed tr so it recognizes standard escape sequences.
513 Merged common escape seq. code from tr and echo into utility.c.
514 - Major work in updating/cleaning up the docs, and getting the
515 new SGML based docs into shape.
517 - BusyBox should now poweroff when asked to do so.
518 - Fixed 'ln -n' and 'ln -s' so they both work properly.
519 * Reorganized signal names in kill.c for better architecture support
520 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
521 * In 0.43, backspace and delete worked properly, but with 0.45,
522 it just echoed a ^? for backspace, and ^H for control-h. This
523 was due to a broken macro in init.c, that is now fixed.
524 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
525 couldn't maintain it very well, so including it was not really
526 very appropriate. Those wanting an fdisk are invited to
527 grab a copy from util-linux.
528 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
529 then be loaded in by 'loadkmap' -- submitted by
530 Arne Bernin <arne@matrix.loopback.org>
531 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
532 * Brand, new versions of grep and sed which use libc regex routines,
533 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
534 "regexp.[ch]" files have been removed. Much help on these from
538 -Erik Andersen, 11 July 2000
542 * Now compiles vs libc5 (which can save lots of space for
544 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
545 help messages (i.e --help). Saves 17k over a full compile.
546 * Added cut and tr from minix, since due to the license change,
547 we can now use minix code. Minix tr saves 4k.
548 * insmod now works. It costs 29k, but imagine an initrd with a
549 staticly linked busybox containing only insmod and sh, a few /dev
550 entries, and a kernel module or two... It doesn't get smaller
551 then this folks (I pity the fool that writes insmod in asm ;-).
552 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
553 * Added a mini ar archive utility, especially written for BusyBox by
554 Glenn McGrath <bug1@netconnect.com.au>
555 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
556 * Added setkeycodes, for those that have wierd keyboard buttons.
557 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
558 <ams@trillian.itslinux.org> for contributing these.
559 * Added 'grep -v' option (inverted search) and updated
560 docs accordingly. -beppu
562 * Replaced the telnet implementation with one written by
563 Tomi Ollila <too@iki.fi> It works great and costs 3k.
564 * BusyBox sh (lash) now supports being used as a standalone shell. When
565 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
566 be invoked as shell internals. Best used when compiling staticly
568 * BusyBox sh (lash) internals now behave as expected wrt pipes
570 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
571 * Fixed update segfault
572 * Fixed mknod -- minor number was always 0
573 * Fixed tar option parsing, so both "tar xvf foo.tar" and
574 "tar -xvf foo.tar" now work (i.e. no "-" before options)
575 (this was very broken in 0.43).
576 * Several contributions from Randolph Chung <tausq@debian.org>.
577 * cp/mv now accepts the -f flag
578 * tail can now accept -<num> commands (e.g. -10) for better
579 compatibility with the standard tail command
580 * added a simple id implementation; doesn't support sup. groups yet
581 * logname used getlogin(3) which uses utmp. Now it doesn't.
582 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
583 * Add support for "noatime" and "nodiratime" mount flags to mount.
584 * Changed 'umount -f' to mean force, and actually use umount2.
585 * Changed 'umount -l' to mean "Do not free loop device".
586 * Fixed basename to support stripping of suffixes. Patch thanks
587 to xiong jianxin <jxiong@uiuc.edu>
588 * cp -fa now works as expected for symlinks (it didn't before)
589 * zcat now works (wasn't working since option parsing was broken)
590 * Renamed "mnc" to the more correct "nc" (for netcat).
591 * Makefile intelligence updates
592 * Changed the way init parses /etc/inittab entries to avoid problems
593 with commands that contain colons in them. Fix thanks to
594 Pavel Roskin <proski@gnu.org>
595 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
596 Fix thanks to Pavel Roskin <proski@gnu.org>
597 * Made "killall" complain (not error and exit) about processes that it
598 cannot find by name -- Pavel Roskin <proski@gnu.org>
599 * Fixed more and ps to have sensible terminal width defaults, thanks
601 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
602 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
603 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
604 * Fixed segfault caused by "touch -c"
605 * Fixed segfault caused by "rm -f"
606 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
607 and "--" support from Pavel Roskin.
608 * Fixed segfault caused by "cp -a -a" and similar abuses.
609 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
610 * "which" rewritten to use stat(). Fixes to improve its compatability
611 with traditional implementations -- Pavel Roskin.
612 * "mount" now reports errors from nfsmount() and assumes NFS mount
613 if ':' is present in the device name - Pavel Roskin
614 * Fixed exit status for killall - Pavel Roskin
615 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
616 * Fixed 'mount -a' so it works as expected.
617 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
618 * Implemented "ping -s", fixed error messages and argument parsing -
620 * Syslogd will not go to background if "-n" is given. Better help
621 and argument checking -- Pavel Roskin
622 * Fixed a small bug that could cause tar to emit warning messages
623 and not extract the first file in a directory in some cases
624 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
625 for helping track this one down.
627 * Fixed grep "Line too long" problem -- John Beppu
628 * Fixed 'grep -q -i B some_file' so it works
629 * math takes input from stdin if no args are given. -- John Beppu
630 * math was renamed to dc. Although it deviates from dc's behaviour,
631 this will probably be remedied in the future. -- John Beppu
634 -Erik Andersen, June 21, 2000
638 Previously, an erronous announcement of BusyBox 0.44 was made, so to
639 avoid possible confusion, we are skipping straight to 0.45, and calling
646 * Major update to the provided documentation.
647 * Busybox now includes a shell! It currently costs 7.5 k (plus an
648 additional 2.5 k if you compile in command line editing). Handles
649 job control, has the usual set of builtins, and does everything
650 except for handling programming statements (if, while, etc...)
651 * Busybox can now work perfectly when /proc is disabled, thereby
652 saving a bunch of memory (kernel /proc support is not thin). This
653 is done by making use of some nice kernel patches I wrote up to
654 support the features that busybox requires and that /proc usually
655 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
656 patch your kernel with the devps patch in the kernel-patches/
658 * Wrote basename, dirname, killall, and uptime.
659 * tar has been completely rewritten by me. Both tar creation and
660 extraction are now well behaved. Costs 7.6k with all optional
661 tar features enabled, and 5k for just tar extraction support.
662 * Added freeramdisk, which will free up all memory associated
663 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
664 and then adjusted a bit by me.
665 * Added tr from John Lombardo <john@deltanet.com>
666 * Added echo and test (from me).
667 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
668 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
669 * Several fixes from Pavel Roskin <proski@gnu.org>:
670 - When `tail' fails to open a file it now exits.
671 - When `syslogd' is given the `-n' option it should still use
672 fork() for running klogd.
673 * nslookup types are now changed to u_int32_t (instead of uint32_t)
674 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
675 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
676 to count hard-linked files more then once). Many thanks to
677 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
678 * Removed /proc dependancies for init and free (while maintaining
679 exactly the same functionality). /proc takes up 90k of kernel
680 space, so it is nice to avoid using it at all costs.
681 * init no longer tries to mount /proc (unless there is less the 1 meg
682 free). Use of /proc (or not) is policy that should be set up in
683 /etc/fstab (or in hardcoded scripts), not in init.
684 * Fixed rebooting when init runs as an initrd.
685 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
686 - update.c rewritten to look more like update-2.11
687 - moveed the inode hash out of du.c and into utility.c to make
688 it a common resource that can be used by other apps.
689 - cp_mv.c now checks inodes to see if a source and dest are
690 the same, and prints an error (instead of endlessly looping).
691 - mv now attempts to do a rename, and will fall back to doing
692 a copy only if the rename fails.
693 - Syslogd now supports multiple concurrent connections
694 * Several fixes from Pavel Roskin <proski@gnu.org>:
695 - Fixes to sort. Removed "-g", fixed and added "-r"
696 - Fixes to the makefile for handling "strip"
697 * An initial telnet implementation was added by
698 Randolph Chung <tausq@debian.org>.
699 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
700 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
701 to match the terminal (defaults to width=79 when this is off).
702 * ps now accepts (and ignores) all options except for "--help" (which
703 as would be expected displays help).
704 * Fixed mount'ing loop devices when the filesystem type was not
705 specified. It used to revert to non-loop after the first try.
706 * all mallocs now use xmalloc (and so are OOM error safe), and
707 the common error handling saves a few bytes. Thanks to
708 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
709 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
710 * Fix symlink following bug in chmod -R and friends.
711 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
712 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
721 * Fairly massive restructuring of umount.c to deal with remounting
722 busy devices read-only. Adds a -r option to control that; it is
723 optionally compiled in with BB_FEATURE_REMOUNT
724 * Added a bunch of functions to mtab.c to interact with the
725 {get,set,end}mntent interface; as it turns out, those functions do
726 not appear to be re-entrant, and that causes a lot of problems with
727 the way umount was originally written.
728 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
729 to be more consistent with sysvinit
730 * Changes to init.c to use the new -r option to umount. Also increased
731 the sleep time between the time the TERM and KILL signals are sent
736 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
737 extensively rewritten from the original cp.c.
738 * Fixed cp and mv so if the source and destination are a the
739 same directory it will print an error and continue.
740 * Also added a warning message to the `mv' usage string saying that
741 this is not GNU mv, and it will break hard links. cp also breaks
743 * ln.c: implemented `-n' switch, no-deref symlinks.
744 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
745 * name buffer overrun guards to prevent future crashes.
746 - Always check exit status.
747 - Purge all use of `creat()', replace with `open()'.
749 - recursiveAction was overriding the value of followLinks thus
751 - isDirectory now takes a followLinks boolean, updated all callers
752 - copyFile had the followLinks logic reversed.
753 * messages.c: New file. Put common error message strings all in
754 one place in an attempt to shrink the binary a little.
759 * changed fsck_minix.c to reduce its .bss size significantly
761 * Made tar creation support in busybox tar optional. You no longer
762 * _have_ to put a "-" in front of tar options. Tar could inadvertently
763 * change permissions and ownership on
764 certain directories pointed to by symlinks.
765 * Made grep and grep -h do the right thing wrt printing
766 the file name (it failed to print files names in many cases).
767 * Fix a namespace aliasing problem wereby if du was built in, the
768 symlink for both du and dutmp would be installed, or then rm was
769 built in, the symlinks for both rm and rmmod would be installed.
770 * Added a closelog() to init.c after loging -- fix thanks to
771 Taketoshi Sano <kgh12351@nifty.ne.jp>
772 * Rewrote and simplified logger. Added the "-t" option, and made it
773 behave itself a bit better.
774 * Optional support contributed by Ben Collins <bcollins@debian.org>
775 for the kernel init chroot patch by Werner Almesberger, which
776 allows init to chroot to a new device, and umount the old one.
777 * Fixed bug that wouldn't let one chown a symlink -- it would
778 always dereference before. -beppu
779 * Fixed a bug where init could have reference already freed memory.
780 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
781 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
782 * Added (and documented) "-n" option for head
783 * Cleanup for a number of usage messages -- also
784 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
785 * Cosmetic fix to busybox.c (Don't print a comma at the
786 end of line if there are no more application names).
787 * Fixed a stupid bug in "head" option handling ("head -n"
789 * Moved commonly used functions "xmalloc()" and "exit()"
790 to utility.c (with proper #ifdef's).
791 * Created a tiny tail implementation, removing -c, -q, -v, and making
792 tail -f work only with a single file. This reduced tail from 6k to
793 2.4k. The bigger/more featured tail can still be had by disabling
794 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
795 * Ping now falls back to doing the right thing if /etc/protocols
797 * Fixed mount and umount. Previously they could leak loop device
798 allocations, causing the system to quickly run out. Fix for umount
799 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
800 * ls formatting on eight charactor user names fixed by
801 Randolph Chung <tausq@debian.org>.
802 * cp could, when copying symlinks, change permissions of the
803 files pointed to by the symlinks.
804 * Several fixes from Pavel Roskin <proski@gnu.org>:
805 - `chown' with 1 argument displayed the error incorrectly
806 - `fdflush', `length' and `printf' crashed if run without arguments
807 - `fdflush' tried to flush itself using *argv
808 - added "skip" and "seek" to dd.
809 - ls no longer messus up output when combining files and
810 directories on the command line
811 * swapoff -a was not working. Now it is.
812 * init did not cleanly unmount filesystems on reboot. Now it does.
813 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
815 * Some architectures (PowerPc) assume chars are unsigned, so they could
816 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
817 * Began converting error handling to use some common routines
819 * syslogd now has better message handling and ignores SIGHUP.
820 * install.sh had a bug preventing installation to the specified
821 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
822 * You can now spefify alternative strip commands -- change
823 also from Gilbert Coville.
829 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
830 by Edward Betts <edward@debian.org>
831 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
832 type commands (file in a directory to another directory) from
834 * Fixed a logger bug that caused garbage to be written to the syslog
835 (unless you used busybox syslog, which hid the bug). Thanks to
836 Alex Holden <alex@linuxhacker.org> for the fix.
837 * /bin/true and /bin/false were echoing a blank line when run.
839 * mkdir -p would print an error when asked to mkdir an existing dir
840 with no interveining subdirectories.
841 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
842 * and support in umount for loop
843 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
844 <bcollins@debian.org>
845 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
846 * fullWrite() not only if BB_TAR is defined, but also
847 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
848 * add some compiler optimizations to further reduce executable size
849 (as a side note, on my machines the largest code is generated
850 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
852 * Compile now won't fail if busybox.def.h defines
853 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
854 referenced, but not compiled)
855 * Fixed a bug in setting TERM for serial console support. TERM now
856 defaults to "ansi" for serial consoles.
857 * Fixed a bug in handling the CONSOLE env. variable for serial
860 -Erik Andersen, Jan 15, 2000
863 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
864 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
865 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
866 for loading application character maps for Unicode fonts.
867 * Major init re-work. init now supports inittab (slightly different
868 but similar to sysvinit), allowing me to get all the policy out of
869 init and into the conf file. It works just fine without inittab
870 being present, but if you dont like the default behavior you can
871 now do something about it. Init is much cleaner as a result.
872 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
873 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
874 * failure of 'logger -p'. -erik Added the -s option to du -beppu
875 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
876 with the 2.0.x Linux kernel.
877 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
879 * Grep -i previously failed on UPPER CASE patterns due to a silly
880 regexp implementation bug that is now fixed.
881 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
882 * Fixed a bug where tar would not set the user and group on device
884 * Fixed a bug where tar would not restore the time to files. Fixed a
885 * major security problem with tar -- it changed ownership
886 of any file pointed to by a symlink to 777 (like say libc....)
888 * cp and mv were very broken when moving directories. I have rewritten
889 them so they should now work as expected.
890 * sed now supports addresses (numeric or regexp, with negation) and
891 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
892 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
893 * Some cosmetic fixes to ls output formatting to make it behave more
895 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
896 * <fwv@myrtle.lahn.de>:
897 - Added gunzip -t, removed gunzip.c dead code,
898 - fixed several typos
899 - Glibc 2.0.7 and libc5 compile fixes
900 * Fixed a bug where 'mknod --help' would segfault.
903 -Erik Andersen, Jan 07, 2000
906 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
907 <tausq@debian.org>. 3 items off the TODO list!
908 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
909 * tail from GNU textutils-1.19, but adjusted
910 to suit my evil purposes. Costs 6k. I'll make it smaller
912 * on reboot, init called 'umount -a -n', which caused errors
913 when BB_MTAB was not enabled. Changed to 'umount -a', which does
915 * init will now try to run /sbin/getty if it is present (for easy
916 integration with the about-to-be-released tinylogin.)
917 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
918 * -l' was failing on long directories, since my_getid was leaking
919 one file descriptor per file. Oops.
920 * Fixed rebooting from init. I'd accidently left some debugging code
922 which blocked reboots.
923 * Fixed reboot, halt (and added poweroff) such that they handle it when
924 init is not at PID 1 (like when running in an initrd).
925 * Added a prelinary du implementation. Some parameter parsing
926 stuff still needs to be added. -beppu (John Beppu
928 * Implemented tee. -beppu Implemented head. -beppu
930 -Erik Andersen, Dec 10, 1999
933 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
935 * df will not exit on error, but will stat all mounted filesystems.
936 * Fixed tar so uid/gid/permissions on extracted tarballs will be
938 * Fixed find -name so it properly uses shell wildcard patterns
939 (i.e. `*', `?', and `[]') instead of regular expressions, which
940 was causing some confusing and unexpected behavior.
941 * Added klogd to syslogd, so now the log will contain both system and
943 * syslogd now creates the /dev/log socket to make sure it is there, and
944 is actually a socket with the right permissions.
945 * I've taken a first step to making busybox not need the /proc
946 filesystem. Most apps don't need it. Those that _require_ it,
947 will complain if you enable them when you disable
948 BB_FEATURE_USE_PROCFS.
950 -Erik Andersen, Dec 5, 1999
953 * Wrote a micro syslogd, and a logger util (to log things to the syslog
954 from the command line or scripts) With both compiled in, costs 4k.
955 * Fixed 'make install' so symlinks are installed in their proper
956 * locations. Changed the build system slightly so that features can
958 or disabled from the busybox.defs.h header file, without trying to
959 compile in a source file named after that featue (unless that file
961 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
962 * -r' both work. dd now properly handles input beyond 1 block from
963 * stdin. Fixed a bug where tar unpacked everything a directories.
965 from createPath into mkdir where it belonged, thereby making tar
967 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
969 last file in the list.
970 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
972 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
973 are presented properly.
977 -Erik Andersen, Nov 25, 1999
980 * fixed dd so it properly defaults to stdin and stdout when no
981 if= and of= are set (fix thanks to Eric Delaunay).
982 * Don't try to close the file descriptor of a pipein tar. (fix also
985 * Made createPath be quiet (again thanks to Eric Delaunay). If
986 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
987 command you define it as will be run if the init script exits.
988 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
989 * NFS support added to mount by Eric Delaunay. It costs 10k when
991 in, but that is still a big win for those that use NFS.
992 * Made 'rm -f' be silent for non-existant files (thanks to Eric
993 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
995 and acts as god intended gunzip and zcat to act. They answer
996 --help and obey the '-c' flag.
997 * Fixed a bug in mv which caused it to not move files when the
1000 * Fixed a decimal-instead-of-octal bug causing mkdir to make
1002 with very wrong permissions.
1003 * chmod would overwrite file permissions instead of modifying them.
1004 Now it properly modifies permissions.
1005 * Init now sends warnings destined for the console to /dev/console to
1007 they show up on whatever the active console it. Otherwise
1008 important messages (for example that the system is rebooting) were
1009 not seen when switched to a different VT.
1011 -Erik Andersen, Nov 17, 1999
1014 * gzip now obeys the principle of least surprise and acts like god
1016 (i.e. it accepts a file name, answers --help, and obeys the '-c'
1017 flag and only then outputs to stdout).
1018 * Fixed more.c to compile autowidth on sparc and set initial winsize
1019 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
1021 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
1022 * tar now accepts --help chmod, chown, and chgrp usage now works
1023 * General usage (i.e. --help) cleanups for most apps umount now parses
1024 * options correctly tar can now unpack tarballs containing device
1026 sockets, and fifos (though it can't pack them up) thanks to Matt
1027 Porter. Creating archives containing these is still left to the
1029 * fixed up the license in more.c to properly point to Bruce Perens.
1031 -Erik Andersen, Nov 11, 1999
1034 * ls -l now displays link names outside the current directory,
1035 Patch thanks to Eric Delaunay
1036 * init now properly handles sparc serial consoles and does a
1037 better job of finding the real console device rather than using
1038 /dev/console which doesn't support job control. Patch also thanks
1040 * more started to read from stdin after the last file was finished, and
1041 options were not parsed correctly (fix thanks to Eric Delaunay).
1042 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
1043 * rm wouldn't remove a symlink unless the symlink was valid. This was
1044 a side effect of the busybox 0.32 recursiveAction() fix. Things
1045 should now work correctly.
1046 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
1047 * it does. sed was appending a \n to the end of lines with
1049 Now it doesn't do that.
1050 * ls -l now bypasses libc6 nss when displaying user/group names.
1051 Now uses my_getpwuid and my_getgrgid.
1053 -Erik Andersen, Nov 8, 1999
1056 * Fixed a bug where init could hang instead of rebooting.
1057 * Removed some debugging noise from init.c
1058 * Fixed ln so it works now (it was very broken).
1059 * Fixed df so it won't segfault when there is no /etc/fstab,
1060 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
1061 is not installed (since they cannot fixup "/dev/root" to
1062 state the real root device name)
1063 * merged some redundant code from mtab.c/df.c into utility.c
1065 -Erik Andersen, Nov 5, 1999
1068 * More changes -- many thanks to Lineo for paying me to work on
1069 busybox. If you have any problems please let me know ASAP at
1070 andersen@lineo.com or andersee@debian.org
1071 * usage() now prints the BusyBox version. This will help folks
1072 realize that they are not in Kansas anymore.
1073 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
1074 * arguments. Now it doesn't do that. kill wasn't properly accepting
1075 * signal names. It does now. Added new apps chvt and deallocvt (I
1076 * should probably add open) Major rewrite of init.c. Code is now
1077 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
1078 * with full regular expressions!). Fixed a stupid seg-fault in sync
1079 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
1080 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
1081 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
1082 * cost of ~1.5k and the need for a rw /etc)
1083 folks to use a real /etc/mtab file instead of a symlink to
1084 /proc/mounts. mount, and umount will add/remove entries and df
1085 will now use /etc/mtab if BB_MTAB is defined.
1086 * Fixed a nice bug in recursiveAction() which caused it to infinitely
1087 hunt through /proc/../fd/* creating new file descriptors if it
1088 followed the /dev/fd link over to /proc. recursiveAction() now
1089 lstat's the file when followLinks==FALSE so it won't follow links
1090 as the name suggests. Fix thanks to Matt Porter
1091 <porter@debian.org>.
1094 -Erik Andersen, Nov 4, 1999
1097 * I added a changelog for version 0.30. adjusted find internals to
1098 * make it smaller, and removed
1100 * Fixed a segfault in ps when /etc/passwd or /etc/group
1101 are absent. Now will warn you and carry on.
1102 * Added in optional _real_ regular expression support (to be
1103 the basis for a future sed utility). When compiled in it adds
1104 3.9k, but makes grep much more capable.
1105 * Checked out using nftw(3) for recursive stuff, but unfortunatly
1106 it wasn't supported before GNU libc 2.1, and some folks use glibc
1107 2.0.7 since it is much smaller than that latest and greatest.
1109 -Erik Andersen, Oct 21, 1999
1112 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
1113 paying me to make these updates. If you have any problems with busybox,
1114 or notice any bugs -- please let me know so I can fix it. These
1118 * busybox can now invoke apps in two ways: via symlinks to the
1119 busybox binary, and as 'busybox [function] [arguments]...'
1120 * When invoked as busybox, the list of currently compiled in
1121 functions is printed out (no this is not bloat -- the list has
1122 to be there anyway to map invocation name to function).
1123 * busybox no longer parses command lines for apps or displays their
1124 usage info. Each app gets to handle (or not handle) this for
1126 * Eliminated monadic, dyadic, descend, block_device, and
1127 postprocess. It was cumbersome to have so many programs
1128 cobbled together in this way. Without them, the app is much
1130 * All shared code now lives in utility.c, and is properly
1131 ifdef'ed to be only included for those apps requiring it.
1132 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
1133 so now each app has the function prototype of (da-dum): extern
1134 int foo_main(int argc, char** argv); which speeds integration
1136 * Adjusted the Makefile to make it easier to
1137 {en|dis}able debugging.
1138 * Changed default compiler optimization to -Os
1139 (optimize for smaller binaries).
1142 * To cope with the new app function prototype and the removal of
1143 monadic, dyadic, etc, the following apps were re-written:
1144 * cat - Works same as always. chgrp, chmod, chown -
1145 * rewrite. Combined into a single
1146 source file. Absorbed patches from Enrique Zanardi
1147 <ezanard@debian.org> that removes the dependency on
1148 libc6 libnss* libraries.
1149 * cp - Can now do 'cp -a' can can copy devices,
1150 pipes, symlinks, as well as recursive or non-recursive
1152 * fdflush - adjusted to remove dependancy on struct
1153 * FileInfo. find - Now includes some basic regexp matching
1154 which will be the basic of a future mini-sed.
1155 * ln - Same functionality. mkdir - Added -p flag to
1156 * feature set. mv - rewrite. rm - Added -f flag to
1157 * feature set. rmdir - Same functionality. swapon,
1158 * swapoff - Combined into a single binary. No longer
1159 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
1161 * touch - Same functionality. date - adjusted with a patch
1162 * from Matthew Grant <grantma@anathoth.gen.nz>
1163 to accomodate glibc timezone support. I then ripped out GNU
1165 * mkswap -- new version merged from util-linux. Can now make
1167 * Replaced the old and star, unstar, and tarcat with the tar
1168 implementation from sash. Now tar behaves as god intended it
1169 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
1170 * dd -- rewritten. Can with with files, stdin, stdout. Added the
1171 * following new apps: loadfont -- added from debian boot floppies
1172 * chroot -- added based on a patch from Paolo Molaro
1173 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
1174 * simple strings ps -- I just wrote it. Has _no_ options at all,
1175 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
1177 internationalization and such to make them smaller.
1178 * sfdisk -- Added from util-linux (minus
1179 * internationalization and such). Probably some other
1180 * changes that I forgot to document...
1182 -Erik Andersen, Oct 20, 1999
1185 This version was a messy pre-alpha. stay away or it will bite you.
1186 -Erik Andersen, Sep 24, 1999
1189 mini-netcat (mnc) rewritten.
1192 Mount now supports -a, and -t auto.
1193 Mount now updates mtab correctly for 'ro'.
1194 More checks screen rows size, outputs bytes percentage.
1195 Printf added as module.
1197 Touch now creates files. -c option for no create.
