"This planet has - or rather had - a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movement of small green pieces of paper, which was odd because on the whole it wasn't the small green pieces of paper that were unhappy." - The Hitchhiker's Guide to the Galaxy.

Toybox 0.4.9 (commit 1385) is out.

New commands added to pending include: lsattr, chattr, inotifyd, rfkill, sulogin, strings, makedevs, killall5, and tar from Ashwini Sharma, arp from Kyungwan Han, sysctl by Bilal Qureshi, partprobe from Bertold Van den Bergh, host from Rich felker, and I did nbd-client and the first 2/3 of mount.

Finished cleanups (commands promoted out of pending): sysctl, rfkill, strings, mkpasswd, makedevs, partprobe, killall5, fallocate, and nbd-client.

(Along the way partial cleanups got made to: last, fold, lspci, ps, bootchartd, init, fsck, telnetd, telnet, vconfig, toysh, iconv, useradd, login, host, openvt, deallocvt, getty, tftpd, and modprobe. But there's still more to do on all of those.)

This time around the static binaries are linked against musl instead of uClibc. (That's why there's no sparc version, musl doesn't support that target yet.)

Documentation:

The help text parser expects lower case "usage:" lines with a blank line after them, so go through and regularize those. Expand the "coding style" section in the docs and move it to design.html. (Not a show stopper for incoming contributions, just an explanation of some of the things I'll do to them during cleanup.) The help text for the "toybox" command now includes the shell script snippet to install symlinks to the toybox binary.

The cleanup page now has descriptions for the full ifconfig cleanup series, among others.

The new toys/examples directory contains hello.c and skeleton.c. The first is a simple hello world program in toybox style, the second is a much more elaborate example program using showing how to use the command line option parsing and how to provide multiple commands in the same C file.

Fixes:

Fix od bug reported by Samuel Holland ("od -v -b" was appending the default output type even though an output type was specified). Ashwini Sharma reported bugs where readfile() was incorrectly freeing its buffer, and where toy_init() was zeroing the wrong data because the field it was using to measure (rebound) had moved (when I moved it back I added a comment why the field needs to be there), fixed a segfault in the dhcp client, and made a 0 length read at the start of password entry count as EOF. Make the "we are not root" test in the init code show the help text. Posix implies that fflush() can return success even when the stream's error bit is set, so call both fflush() and ferror() from xprintf().

Isaac Dunham pointed out that bloatcheck couldn't deal with diff implementations that only implement "unified diff" format, and that some diff implementations can't handle nonseekable input (I.E. reading from a pipe). Bugfix so "help -a" works again. Option parsing on nohup now stops at first nonoption argument. Fix segfault in "which" if PATH wasn't set, which was actually a bug in lib function find_in_path(). Made rm -rf of chmod 000 directories actually remove them.

The build now passes the same $CFLAGS to the library probe as the final build, because arch linux is so broken it provides different sets of libraries for static and dynamic linking.

It turns out sprintf("%.123s", str) is counting characters, not bytes, so globally enabling locale support opens stack smashing vulnerabilities. So there's a new TOYFLAGS_LOCALE you set in toyflags when you want the setup code to setlocale().

Upgrades:

Isaac Dunham extended cpio to archive unreadable empty files, and I taught it to set uid/gid and timestamp when extracting archives. Isaac also added tests for cpio, link, and du, added lspci -i, made the pci database parsing skip # comment lines, merged logname and whoami into id.

Daniel Verkamp sped up md5sum about 30% with some loop unrolling, making it actually smaller in the process. I added -b flags to md5sum and sha1sum for "brief" output that's just the hash with no filename. (I'm aware other implementations use that for MSDOS "binary" mode, and don't care.)

When building standalone commands (scripts/singleconfig.sh commandname), the build now switches on all the sub-options of the command so we get a standalone version with all the bells and whistles enabled.

Add -ds flags to date and document +FORMAT escapes. Add the shell NOP command ":" as an alias for true (for toysh).

Add uClibc probe for iconv() and fallocate. (The fact it didn't always build against uClibc is why fallocate wasn't enabled in defconfig before.)

The umount command now does an losetup -d on the device by default, so we don't leak loopback devices. Bugfix to losetup so "losetup /dev/loop0 filename" actually works again.

Divya Kothari sent in test suite entries for ls, ln, rm, mv, printf, dd, and renice. Then a second round for lsattr/chattr, mount, chmod, pgrep/pkill, groupadd, groupdel, and useradd. Several of these uncovered bugs, still working to fix them.

There are now free() functions for the predefined llist types and a dlist_terminate() function to break doubly linked lists. The new generic_signal() handler either sets "toys.signal" or writes a byte to toys.signalfd with the signal number if signalfd isn't -1 (which it's initialized to in toy_init).

The option parsing logic can now detect when a double fits in a long and use the more precise type for floating point arguments (the FLOAT macro contains the type used). The human_readable() function now just outputs decimal kilo/mega/gigabytes (so when du -u says 5.0G it means 5.0 billion bytes). The build infrastructure now notices duplicate commands (so if you cp toys/pending/command.c toys/other/command.c and forget to delete the first one, the build break is now more informative).

And to this end they built themselves a stupendous supercomputer which was so amazingly intelligent that even before the data banks had been connected up it had started from "I think therefore I am" and got as far as the existence of rice pudding and income tax before anyone managed to turn it off. - The Hitchhiker's Guide to the Galaxy.

Toybox 0.4.8 is based on commit 1262. And about time too.

The big news is that the build no longer needs python to generate help.h, that's now done in C. The help text generation is also collating help text from multiple options, merging command line option blocks and usage: lines. There's even a new help web page.

New commands: Ifconfig, cpio, and su were cleaned up the rest of the way and promoted out of pending. That saga is mostly explained on the cleanup page. Vivek Bhagat's freeramdisk, Isaac Dunham's fsfreeze, and Felix Janda's iconv are also new.

In pending: Ashwini Sharma's team submitted tcpsvd, udpsvd, telnet, telnetd, last, more, groupdel/delgroup, arping, brctl, ftpget, ftpput, printf, reset, and added ipv6 support to traceroute. Kyungwan Han's team submitted modprobe and getty. Vivek Bhagat submitted openvt and deacllocvt. Samuel Holland submitted fold. I wrote a new inflate (zip/zlib/gzip decompression) implementation in compress.c, and still need to do a corresponding deflate (compression-side) and plug them into gzip and zip and so on. (Right now it does zcat.)

Several commands (vmstat, login, du, vconfig, mountpoint, free, chroot, cut, touch, modinfo, expand) predate the "pending" directory, and are thus in other directories but still need cleanup. Of these, vmstat got some work this time (which would be much easier other vmstat implementations documented what their output actually meant).

Upgrades: Ifconfig grew /prefix netmask support (ala 1.2.3.4/24). Grep now has -zZ to handle null terminated data, cksum grew -H for hex output. Upgraded od so the fields align better when producing multiple output types. Help has -a and -h options (all commands, html output). Bugfix to blkid building for a 32 bit target. The date command can actually set dates now. The O_NOFOLLOW compile time probe didn't work with cross compiling, so it's back to an #ifdef test in portability.h. Nathan McSween sent in a bugfix to od and a portability fix in the common library code. Ashwini Sharma spotted a bug in pidof -o, and added verbose (-v) options to mkdir and ln, and suggested killall should have an -s option and allow -l to take zero arguments. Ashwini Sharma and Felix Janda upgraded tftpd. Fixed dumpleases still using toynet.h after that was removed. Corrected killall return code and error reporting. Isacc Dunham fixed bugs all over the tree, did cleanup on a bunch of pending commands (getty, ftpget, init, openvt, modprobe...), and clarified find's help text. Tom Sparrow ran three different static analyzers on the code, which resulted in a few cleanups. The peek()/poke() functions now use "volatile" to prevent broken compiler "optimizations" to do with aliasing.

Build stuff: Each FOR_xxxx macro now has a complementary CLEANUP_xxxx macro, so you can put multiple commands with different command line options in the same .c file, so they can share infrastructure outside of lib. (This let the bunzip logic move out of lib into bzcat.c.) See XXX for example. i

The headers #included in toys.h are now grouped by standard, and headers not listed in Posix or LSB were moved to portability.h. The old xregcomp.h was folded into lib.h because it's posix (and supporting oddball uClibc configurations isn't as important as it once was).

Regression tested against Ubuntu 8.04 to fix up bit-rot in defconfig build on older systems. (We depend on Posix-2008, but not necessarily the absolute latest build environment.)

In lib: lib/xwrap.c added xgetpwnam(), xchroot(), and lib/lib.c now has names_to_pid(). xsetuid() was replaced with xsetuser() which takes a struct passwd and sets both gid and uid, mkpathat() got factored out into a library command, get_int_value() became atolx_range(), and xmsprintf() is now just xmprintf(). The bunzip2 logic moved from lib into bzcat.c.

Documentation: new help page with the help text for all the defconfig commands, using the new help -ah output. The source code walkthrough now says more about #including header files, and how the generated/* directory works. The design page has some new paragraphs about trading of different kinds of simplicity, and why comments aren't a substitute for good code. The README no longer trails off into obvious unfinished confusion at the end. Each page on the website should now have its own title.

"Space," it says, "is big. Really big. You just won't believe how vastly, hugely, mindbogglingly big it is. I mean, you may think it's a long way down the street to the chemist's, but that's just peanuts to space." - The Hitchhiker's Guide to the Galaxy.

Toybox 0.4.7 is based on commit 1122.

New commands: Brad Conroy submitted blkid. Elie De Brauwer submitted reboot, halt, and poweroff. Strake's nl got cleaned up and promoted from pending to posix. In addition, the existing chvt and vconfig got some cleanup.

That said, I haven't nearly kept up with the flood of new commands going into pending: Ashwini Sharma's team submitted dd, dumpleases, traceroute, top, useradd, groupadd, mkpasswd, tftpd, and an fsck wrapper (with no filesystem drivers yet). Isaac Dunham sent in cpio.

Bugfixes: Jeroen van Rijn added a user count to uptime. Elie De Brauwer added -e to watch, removed a memory leak, and fixed a terminal size problem. William Haddon made xargs call its command line once even with blank input (the standard is vague, but builds expect it), and fixed an off by one bug where grep didn't malloc enough space with -E (leading to a segfault). I fixed a glitch in bunzip2 (same one as went into busybox since they're using the code I wrote), in od to fix -t co, -J, and -c options. Add uname -o as a synonym for -s. Build fix to never use $CC without prefixing it with $CROSS_COMPILE (since $HOSTCC could be different). Anca Emanuel spotted a typo in the web page.

The compile-time command line option parsing got rewritten (ported from bash to C), which should speed up builds a bit and allow code controlled by --longopts to drop out properly when disabled in the configuration. Terminal querying got refactored. Patch's -x option is now more informative (a debug thing if you're trying to figure out why a patch didn't apply). The "toynet.h" file got folded into toys.h since musl supports it and micromanging uClibc options isn't very interesting anymore. The test suite now uses scripts/single.sh when testing a single command.

"Think of a number," said the computer, "any number." Arthur told the computer the telephone number of King's Cross railway station passenger inquiries, on the grounds that it must have some function, and this might turn out to be it. - The Hitchhiker's Guide to the Galaxy

Toybox 0.4.6 is based on commit 1068.

This release adds several new commands: Felix Janda wrote paste and fallocate, Kyungwan Han submitted eject, Strake contributed grep, Ashwini Sharma added pmap (and a testsuite entry for grep), Lukasz Skalski sent pwdx, Isaac Dunham posted acpi, and I did timeout and umount.

The ls command now has a --color=auto option (suggested by Rich Felker). The multiplexer now has a --help option so you can say "./toybox --help blah" instead of using the built-in "help" command. (Which is a shell built-in. Try it on your command line, it's like man for shell builtins. But a certain other project has conditioned people to expect --help, so...) I forget who heehooman at gmail is but they pointed out unshare needed PID and UID namespace support.

Pending

A lot of new commands in toys/pending, to the point the next release should probably just focus on cleanup and review of this backlog. We've got klogd, dhcp, dhcpd, watch, route, and ps from Ashwini Sharma (and an fsck wrapper but no fsck.fstype engines yet), syslogd, pgrep, and pkill from Madhur Verma, netstat by Ranjan Kumar, test by Felix Janda, lspci by Isaac Dunham, nl, su, and renice by strake (I.E. M. Farkas-Dyck), and sysvinit by Kyungwan Han.

Some cleanup work on existing pending commands that aren't ready to promote yet: I did a few more rounds on ifconfig and Isaac Dunham's did several cleanups to xzcat, Felix Janda cleaned up logger and syslogd...

Also some cleanup work on commands that predate the pending directory, but weren't quite polished when they went in, most prominently du, expand, and touch.

Infrastructure

The new scripts/single.sh builds a standalone command without the multiplexer, although not all commands can be built that way yet (NEWTOY yes, OLDTOY no) and the space savings aren't anything to write home about. (If a command needs the option parsing logic at all, it needs all of it.) If you're curious, you can do:

make defconfig
make
mkdir singles
for i in $(./toybox)
do
  echo $i
  PREFIX=singles/ scripts/single.sh $i || break
done

(And then wait a long time and watch almost half the builds fail.)

There is now libbuf analogous to toybuf, another global 4k buffer this time for use by lib/ code instead of command code.

The lib directory got split up a bit, lib/pending.c contains functions not yet used by anything outside of toys/pending/*, and lib/xwrap.c contains functions that wrap other functions and handle failures (via error_exit). This leaves lib/lib.c containing actual new functions.

General improvements and bug fixes to argument parsing. The [-abc] exclude logic should now clear arguments slots when disabling options. Bare --longopts should work now and be able to report errors using their name, the new ; option allows optional arguments to longopts only suppliable with = (I.E. --color and --color=auto but not --color auto).

I'm gradually weaning the code off of itoa()/utoa() because sprintf does this already. In this case "simple" probably means "let libc do it for us".

Rewrote for_each_pid_with_name_in() and renamed it to just names_to_pid(). It shouldn't get confused trying to compare absolute and relative paths quite so much anymore.

lib/llist.c grew a new dlist_pop() function for removing a doubly linked list entry while maintaining a circular list; tail and patch are using it now.

The musl guys suggested a new optimization flag (-fno-asynchronous-unwind-tables) that shaves about 10% off the binary size by removing a C++ism that crept into gcc's idea of C. While I don't normally try to micromanage the compiler, "-fstop-being-stupid" is a thing you have to hit gcc with from time to time.

Bugfixes

Felix Janda and I did a largeish rewrite of tail to finally make it work right (we think). Still need to implement tail -f someday (the tricky bit is making -f follow multiple files at once). Felix also reported a bug in xpidfile.

Juhani Haverinen pointed out that python 3 doesn't work with config2help.py, so the detection logic looks for python2 (until I get around to rewriting that in C). Elie De Brauwer then fixed our first attempt at this, and also fixed uname's help string.

Ashwini Sharma pointed out the build was making a FLAG_ macro for " " which broke some configurations. (That's a control character, not a command line option.)

Jacek Bukarewicz pointed out a bug in chdir permission handling, and a way to make env segfault. Both should be fixed now.

The new function xexec_optargs() replaces calls to xexec(toys.optargs) to avoid freeing and reusing optargs during option parsing screwing stuff up (such as netcat's exec mode).

The stat command's %a output was padded with leading zeroes, which didn't match anybody else's behavior and thus made the test suite hiccup between TEST_HOST and testing toybox. (If you go "TEST_HOST=1 scripts/test.sh command" it sanity checks the tests against the host implementation.)

Last release, "mkdir sub/sub && chmod 007 sub/sub && rm -rf sub" didn't delete sub and didn't exit with an error either. Neither was correct, rm should now be fixed.

"Time is an illusion. Lunchtime doubly so." "Very deep. You should send that in to the Reader's Digest. They've got a page for people like you." - The Hitchhiker's Guide to the Galaxy.

Toybox 0.4.5 is based on commit 941. It adds uuencode and uudecode from Erich Plondke, and enables Luis Morales' "who" by default. Felix Janda and I cleaned up last year's "stat" submission and enabled it. Ivo van Poorten added "groups". Andre Renaud added "lsusb". I implemented "split", "pivot_root", and "mv".

The "help" command is implemented differently now (lib/help.c) and each command can now understand --help (including both "toybox --help" and "toybox --help command" in the multiplexer).

The "pending" directory has several commands (find, xzcat, nbd-client, logger, expr) which work but are not enabled by default pending further cleanup. Ifconfig is enabled, but still in pending because it's only 2/3 cleaned up. (It's an awkward halfway state but I'm not holding up the release for it.)

I'm documenting the cleanups to teach more people to do it, but the writeups aren't caught up yet. The roadmap also got updated a bit with further analysis of other projects, and the README and about pages got updated.

Fixed _another_ "ls -C" segfault when terminal size can't be detected, condensed the ls help text to fit on one page, implented --color, and taught -l to print the major, minor numbers when showing block/char devices. Argument parsing now handles "--" properly (to end option checking), and the infrastructure can now handle bare --longopts that have no corresponding short option (both were implemented before but didn't work). Fixed an old bug in "patch", chmod grew -f, who grew -a. Isaac Dunham fixed "-" vs "_" handling in modinfo, added a "firmware" output field, added -b and -k support, and taught it that the ".ko" extension means to look for the file at the specified path instead of under /lib. Felix Janda moved file permission display code to lib so ls and stat could share it. Ashwini Sharma spotted a bug in xabspath when the last path component exists but we haven't got permissions to open it (ala readlink -f /dev/sda as a normal user).

In the build infrastructure, scripts/findglobals.sh finds leaked global variables. (Leaked means they aren't part of the global union: Other than glibc debris, toybox should define "this", "toy_list", "toybuf", and "toys", and that's it; the rest add memory footprint to every command for the benefit of just one command; use GLOBALS() to stick 'em in the union.) Static linking against libraries other than the host's libc now applies to feature probes for unshare and such. Neuter stupid internationalization support that makes various host "sort" commands put things in an order other than alphabetical (breaking the multiplexer's binary search on command names).

You should now be able to build from a source control snapshot on a build system that hasn't got python: if you disable CONFIG_TOYBOX_HELP. (The release tarballs ship generated/help.h, but it's not in source control. Eventually I should rewrite that python script in C.)

LICENSE TWEAK: After discussion on the mailing list the "2 clause BSD" license got slightly simplified so the first paragraph now says:

Permission to use, copy, modify, and/or distribute this software for any purpose with or without fee is hereby granted.

It used to continue "provided that the above copyright notice and this permission notice appear in all copies", but A) what's the point? B) does "all copies" mean binaries, or just source code, or what? C) lots of projects that consider BSD and GPL compatible have files with both license notices on them (sometimes at opposite ends of the file to make the conflict less obvious) because "all copies must include this function" would violate the GPL but "all copies must include this magic text blob" somehow don't?

I don't want to have to care about this anymore. The tweaked version is more or less public domain with a liability disclaimer, but we're still calling it BSD (sometimes "0 clause BSD") to avoid explaining.

"Ford, you're turning into a penguin. Stop it." - The Hitchhiker's Guide to the Galaxy.

Toybox 0.4.4 is based on commit 813, adding the "time" and "readahead" commands, plus some bugfixes.

The "cp" command now implements the -s symlink option, plus bugfixes getting various corner cases right as used in actual package builds. "id -Gn root" should now print root's groups instead of the current user's. Several build fixes so toybox builds under Ubuntu 8.04 again (which is about as old a build environment as you can expect to find posix-2008 features in).

Unfinished commands have generally been moved to "toys/pending". Everything else should "default y" to participate in make defconfig. Several of those pending commands got some basic cleanup so allyesconfig should at least compile (although defconfig is still what's useful).

Significant roadmap updates, checking several other multicall binaries (klibc, sash, sbase, s6...) to see what commands they include.


January 18, 2013

This must be Thursday. I never could get the hang of Thursdays. - The Hitchhiker's Guide to the Galaxy.

Toybox 0.4.3 is based on commit 793. There are now exactly 100 commands in defconfig (of a little over 220 on the todo list).

Elie De Brauwer added the rev command, cleaned up tac, implemented the -s and -f flags for seq, added -v and -i to killall (and fixed killall not to kill itself before finishing its pid list), and added to the test suite. Felix Janda added -m to mkdir, pwd -L and -P, and more test suite entries.

Rob Landley added the losetup command, and fixed the existing ls, cp, and readlink commands. The segfault in ls happened when it couldn't determine the screen size (last release changed the default to -C and a screen size of 0 made column view unhappy), and cp got an extensive rewrite bringing it up to date with the dirtree changes and fixing a number of things it never did right in the first place. The xabspath() code in the library now handles a symlink after ".." properly (and the test suite checks for it).

Infrastructure-wise the code is better about automatically setting the error return code properly. Now error_msg() sets the exit code to 1 if it's still defaulting to 0, and the global exit path does a fflush(NULL) with error bit check rather than trying to be quite so granular about flushing. (That means if we use printf() instead of xprintf() it still exits with the right error code, it just doesn't end the program early on an output error.) Minor bugfix so TOYBOX_DEBUG doesn't always warn about the lack of suid bit when toybox is built with at least one STAYROOT command. Bugfix for the option [grouping] logic (and then further fixes to the error reporting pointed out by Ashwini Sharma). dirtree_handle_callback() now has a prefix like the rest of the dirtree functions. A lot of stuff doing manual path handling was switched to using libc basename() (including, embarassingly, the basename command), which means it now correctly detects "/trailing/slash/" which the previous code didn't.

Also, last release included some accidentally checked in debug code that disabled compiler optimization, so the binary size bloated a bit. It's back to -Os by default now.

"The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair."

- The Hitchhiker's Guide to the Galaxy.

Toybox 0.4.2 is based on commit 749 and is just a resync. Linux 3.7 came out, meaning it's time to do an Aboriginal Linux release, and that should use a stable version of toybox. So here's a new stable version.

The new commands are cut (from Jason Kyungwan Han), touch (from Choubey Ji), expand (from Jonathan Clairembault, and he fixed a bug in login), and rm (from Rob Landley). Felix Janda added UTF-8 support infrastructure (for non-ascii character sets) with a config option. Elie De Brauwer added tests for cat and sha1sum, and -so options to pidof. The "ls" command defaults to -C (column view) now, and "readlink" now supports -fenq.

Portability work: toybox should now build against the musl C library, and against older glibc versions (circa 2008, much before that and kernel features we depend on start to drop out).

The whole codebase got reindented from "one tab" to "two spaces" per level. The option parsing logic now understands [groups] of commands (when more than one in a group is selected it can switch the others off, or error out, or other things). The error_exit() infrastructure can now longjmp back to an earlier point instead of exiting. Each toys/* directory now has a README, the first line of which is the fancy name menuconfig uses for the directory (so no more hardwired directory list in scripts/genconfig.sh).

Fixed a filehandle leak in getmountlist(). Pass parent pointer to dirtree_add_node() so it can give error messages with full path. The yesno() function now always reads from stdin and writes to stderr (we can retry tty checking complexity once we've got commands needing it).

The open group broke their website so the old links to POSIX 2008 now need to start with pubs. Some of the links in the tree have been updated, others haven't while I wait to see if their webmaster notices and fixes it.

(I note that the current rm implementation is not technically posix compliant because the standard requires infinite recursion depth and the current implementation uses one filehandle per level. I can add a config option to do it Posix's way, which is more brittle and needs extra security checks, but am waiting for somebody to complain first. The default "ulimit -n" is 1024 filehandles, so drilling down over 1000 nested subdirectories).


November 13, 2012

"Rule Six: The winning team shall be the first team that wins." - The Hitchhiker's Guide to the Galaxy.

Toybox 0.4.1 is based on commit 691.

Elie De Brauwer contributed usleep, Ashwini Kumar contributed du, and Kyungwan Han contributed vconfig. Other new commands include switch_root and md5sum, and the remaining shell wrappers are now proper commands (dos2unix, unix2dos).

The patch command now supports -l, and gethostname is now enabled by default. The df command follows symlinks to get the actual device name. Felix Janda added -m support to wc (for utf8).

On the infrastructure side, the commands have now been grouped into "posix", "lsb", and "other" subdirectories (for things required by Posix-2008, the Linux Standard Base 4.1, and commands in neither). This affects menuconfig and the actual source layout (toys/cp.c is now toys/posix/cp.c, and so on). An android directory is planned (see the updated android roadmap analysis).

The FLAG_ macros for command option parsing and TT alias for the command's global block are now automatically generated, commands should #define FOR_commandname before #including to get the macros for that command.

An upgrade to the build infrastructure now allows commands with _ and - in them, such as switch_root.

Bugfixes: Avery Pennarun spotted a case where ls showed uid twice instead of uid and gid, and that nice was using the wrong range of numbers. The ls command also recursed inappropriately last time (not quite properly converted for the dirtree changes last release), and now it's fixed. Roy Tam pointed out a glitch in sh, and fixed df's percentage calculation to match the POSIX spec. The kernel build didn't like our mktemp and it does now. The wc command wasn't quite posix compliant (trailing spaces break stuff). The ls command recursed inappropriately last time (not quite properly converted for the dirtree changes last release), and now it's fixed. The catv command wasn't displaying byte 255 correctly. Some lib fixes (thinko in xpidfile). Fixed uname -m when running a 32 bit x86 binary on an x86-64 host (it lies and says the system is i686, i586, or i486 depending on what the toolchain that built the binary supported. This makes builds in a 32 bit chroot on a 64 bit kernel break less.) The df command was checking partitions in the wrong order (displaying undermounts instead of overmounts: this used to work but some library code changed out from under it and it wasn't updated to match until now). Felix Janda filled out the test suite some more. The patch file creation logic got tweaked several times to successfully apply more patches. Support for older (pre 2.10) glibc versions was added to portability.h.

Miscelaneous cleanups all around (mknod, sha1sum, logname), including a rewrite of taskset to be less dependent on libc getting the headers right. All the command headers should now point to the current relevant standards document, where applicable.

This news page had old news entries from before the relaunch moved into a separate oldnews page.

I forgot to create static binaries last time, but they're back now.

"Ford", Arthur said. "There's an infinite number of monkeys out here who want to talk to us about this script for Hamlet they've worked out." - The Hitchhiker's Guide to the Galaxy.

Toybox 0.4.0 is based on commit 640.

The new status page is calculated from the roadmap info, and should be easier to keep up to date in future.

Andre Renaud contributed od and modinfo. Elie De Brauwer contributed taskset, bugfixes to cmp and tail, and tests for sort and tail. Kyungwan Han contributed passwd. Gaurang Shastri contributed w. Ashwini Sharma spotted a case where dirtree was adding extra slashes to a path.

I rewrote od, cleaned up comm, documented the llist and dirtree infrastructure, added an -r option to date (and fixed a bug where -u wouldn't override /etc/localtime), fixed bugs in chmod +stw, fixed ls to show suid bits properly when the corresponding executable bit wasn't set, and worked around a longstanding glibc bug where static linking prevents stdout from automatically flushing pending output on exit.

"For a moment, nothing happened. Then, after a second or so, nothing continued to happen." - The Hitchhiker's Guide to the Galaxy.

Toybox 0.3.1 is based on commit commit 607. It's mostly a bugfix release for ls -l (which was unhappy on targets other than x86-64), plus a new "date" from Andre Renaud and rewritten chgrp/chown which now support the full set of posix flags, plus a little work on the test suite and some more header tweaks towards eventual compatability with the musl libc.

The todo list runneth over, but "release early, release often", so here it is. The roadmap and documentation are a bit behind, and I've got ~40 pending submissions to review. I need to catch up...

"For instance, on the planet Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much - the wheel, New York, wars and so on - whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man - for precisely the same reasons." - The Hitchhiker's Guide to the Galaxy.

It's well past time for toybox 0.3.0, so here it is, based on commit 595, and the statically linked prebuilt binaries should actually be statically linked this time (thanks Ashwini Sharma for spotting that).

It's hard to figure out where to cut a release, because development doesn't stop. "Long before now" is the obviuos answer, of course. The project's maintainer also moved house during this development cycle, which threw things off for a bit (so many boxes). Releases should hopefully be a bit more frequent from here on.

The big things Rob worked on this time were the new dirtree (directory tree traversal) infrastructure, and a complete rewrite of ls using that which should now implement all 26 posix options.

Georgi Chorbadzhiyski added printenv, whoami, mkdir, mkfifo, chmod, chown, chgrp, and uniq. He also added fraction and extension support to sleep (so if you need a quarter-second sleep, it can do that now), and fixed a build bug on slackware.

Daniel Walter contributed a string to mode_t parser (in use by chmod and mkdir -m). Ilya Kuzmich contributed comm. Elie De Brauwer added mountpoint, vmstat, logname, login, and mktemp. Kevin Chase did some portability cleanups. Pere Orga fixed some documentation.

The "tac" and "clear" commands are now normal commands instead of shell wrappers, and the header #includes have been cleaned up a bit to remove deprecated functions and attempt to increase compatability with the bionic and musl C libraries, "tail" should now use lseek() for large files, and "id" got some cleanups and bugfixes.

The new TOYBOX_FLOAT configuration option selects whether or not to include floating point support (for embedded targets where that's problematic).

Several random bugfixes: unshare() might actually build portably now, yes 'n' | cp -i should no longer bypass stdin and prompt via the tty, the SUID support no longer drops permissions going through the toybox multiplexer command, and a bugfix to xargs -0 means it should no longer segfault. (I have a pending bug report about xargs not doing the full posix whitespace handling that -0 obsoleted, but I'll deal with that next release.)

The build infrastructure is now automatically generating FLAG_ macros for the options, but currently with the wrong names. Some more macro glue is necessary, which I haven't quite figured out how to do yet.

A defconfig toybox at the start of the $PATH has successfully built Linux From Scratch (in my Aboriginal Linux project). The commands that 'default n' in the config are often still broken, cleanup is ongoing. (The new dirtree stuff broke several of them that haven't been converted yet, but if I wait until everything works we won't have a release before 1.0, so here's a checkpoint.)

"They went unnoticed at Goonhilly, passed over Cape Canaveral without a blip, and Woomera and Jodrell Bank looked straight through them. Which was a pity, because it was exactly the sort of thing they'd been looking for all these years."

- The Hitchhiker's Guide to the Galaxy.

Here's toybox 0.2.1 based on commit 512. This time around, there are statically linked prebuilt binaries for various embedded targets.

It's been a busy few weeks, almost entirely due to new contributors. (I have not quite been keeping up.)

Elie De Brauwer contributed free, uptime, swapon, swapoff, lsmod, mknod, insmod, rmmod, and fixed a bug in basename. Andre Renaud contributed ls, ln, realpath, and hostname. Andres Heck contributed pidof and killall. Daniel Walter wrote kill and extended id. Timothy Elliott contributed tail and tests for cmp. Frank Bergmann sent a warning fix. Bryce Fricke added -i to cp. Nathan McSween pointed out an optimization. Georgi Chorbadzhiyski fixed cross compiling to work more reliably.

(My own contribution this time around was just tightening up other people's code, a build fix to unshare, some random bugfixes, and so on. My only new code this time around was writing a bash replacement for the existing python bloat-o-meter.)

Last time (the 0.2.0 release) included the first pass at an id command from Tim Bird, env and basename from Tryn Mirell, cmp and head from Timothy Elliott, more bugfixes from Nathan McSween and Elie De Brauwer, and Luis Felipe Strano Moraes did a first pass at the who command plus other bugfixes and optimizations.

(For that release I did xargs, cal, truncate, unlink, nohup, tty, wc, link, dirname, unshare, and various infrastructure tweaks, but it took me 3 months and those guys did their stuff in a week or so.)

"for though it has many omissions and contains much that is apocryphal, or at least wildly inaccurate, it scores over the older, more pedestrian work in two important respects..."

- The Hitchhiker's Guide to the Galaxy

Here's the first BSD licensed release, toybox-0.2.0, more a synchronization point than anything particularly useful. 47 commands in a reasonably ready-to-use state (what "make defconfig" builds), another ten or so partially finished stubs ("make allyesconfig"), and several patches pending on the mailing list I need to review and merge.

More to come...


November 15, 2011 - Back from the dead, Toybox is now under a 2 clause BSD license, and aiming to become the default command line implementation of Android systems everywhere.

More to come...


Old news from before the relaunch.
