Zaphod Beeblebrox was amazingly good at his job.</p> 15<p>- The Hitchhiker's Guide to the Galaxy</p></blockquote> 16 17<p>Despite everything, <a href=downloads/toybox-0.7.3.tar.gz>Toybox 0.7.3</a> 18(<a href=https://github.com/landley/toybox/releases/tag/0.7.3>git commit</a>) 19is out. The <u>new commands</u> this time are <b>ftpget</b>, <b>ftpput</b>, <b>microcom</b>, and <b>ascii</b>.<p> 20 21<p>We also had two command _demotions_ out of defconfig: 22<b>hostid</b> got moved to toys/example and 23switched to "default n" because despite <a href=http://pubs.opengroup.org/onlinepubs/9699919799/functions/gethostid.html>still being in posix</a> 24the concept of a unique 32 bit number identifying a system is something 25Linux outgrew about the time Pauline Middelink wrote the first IP 26Masquerading code. And Elliott did a complete rewrite of <b>dmesg</b> introducing 27two codepaths that I didn't get a chance to unify and didn't want to 28hold up the release for, so that's back in pending.</p> 29 30<p><u>New features</u>: Rob added units to <b>find</b> -atime and friends 31(with the legacy -amin alias). Elliott added color and -w to dmesg, fallocate 32-o, and improved file's ELF parsing. Steve Muckle added -d and finit_module 33support to modprobe. Rob and Elliott tweaked the 34ps/top display format a bit more (extending the USER field from 8 to 18 chars 35and putting + at the end of string fields that got truncated). 36df -a isn't entirely new, but wasn't documented and needed a bugfix.</p> 37 38<p><u>Bugfixes</u>: 39Last release broke oneit because -c didn't get moved to xopen_stdio() (oops). 40Rob and Elliott simultaneously spotted ps padding each line to 99999 41chars when there's no tty (serial console or adb); now it pads to 80 in 42that case but also switches on -w to avoid field truncation. The "tty" 43field also sometimes had trailing debris (that's fixed now). And "top" was 44endlessly redrawing with out tty because receipt of the ANSI size probe 45results would set SIGWINCH, and handling that sent another ansi probe. (Sigh.) 46And while we're there, replace "ADDR" with "BIT" in ps -l so there are 47more than 4 chars left for the "CMD" field on 64 bit systems.</p> 48 49<p>Izabera pointed out that split -b and -l can't mix, and suggested seq should 50multiply to avoid accumulating rounding errors from repeated fractional 51increments. Wang Xiao Jian fixed a bug in sort -k. 52Elliott let getprop use the @ character in property names, and 53Dimitry Ivanov removed the name length limit for system properties. 54Elliott also improved some error reporting and improved top -H's display 55of thread names. 56 57<p>Josh Gao pointed out that recursive operations on . and .. could be ignored 58in chmod -R (and the resulting generic fix to dirtree_notdotdot() fixed 59it in several other places).</p> 60 61<p>Justin Cormack caught tar producing a warning to stdout that screwed up 62"tar c" to stdout. 63Rob fixed an option parsing bug (where switching off a --longopt in menuconfig 64confused the parser), and another one where an option excluding itself 65(ala "abc[-ab][!abc]" with "command -a -b") would segfault.</p> 66 67<p>There's some sort of gcc stack over-optimization bug where musl-libc's 68version of vfork() doesn't get marked with attribute(returns_twice) so 69stack varabiles in the same function after that get semi-randomly overwritten 70when the optimizer decides to reclaim the space. So add the attribute 71to the function the XVFORK() wrapper macro calls. (It's a nommu thing.)</p> 72 73<p>Fixed a couple variable size mismatch bugs that were only tested on 64 bit 74(printf %x 64) or only tested on 32 bit (modprobe), removed some 75unnecessary casts in stat.</p> 76 77<p>Continuing attempts to build under Android NDK brought up that posix 78defines the global 'stdout' as a macro, which older versions of bionic 79turned into an array member, but a function was using it as an argument 80name. (This worked in the AOSP build because it only builds against current 81bionic, where there's a global 'stdout'.)</p> 82 83<p>Several commits argued with clang's warning generation, eventually 84settling on a variant of __attribute__((__shut_up__)).</p> 85 86<p>Android should no longer give spurious error messages 87when you "ps -A | head" about EPIPE on output. (Older versions of bionic 88set an error handler on SIGPIPE, but it shouldn't do that now. More recent 89versions of adb set the SIGPIPE handler to SIGIGN instead of SIGDFL, 90leading to write returning an error message instead of silently killing 91the program. So we set it back to the default.)</p> 92 93<p><u>Docs</u>: 94Removed website link to the gmane archive (which didn't survive gmane's 95change of ownership). The FAQ now answers a _second_ question. (Woo!) 96Some roadmap updates.</p> 97 98<p><u>Build tweaks</u>: 99Upgraded "make install_airlock" target to only warn about missing 100commands (unless $PEDANTIC is set) when it sets up the hermetic build 101path. (The plan is still to implement everything but the toolchain 102binaries in toybox, but in the meantime we're symlinking other stuff from 103the $HOST that isn't ready yet. See 104<a href=https://github.com/landley/mkroot>mkroot</a> for an example using 105this.)</p> 106 107<p>Elliott and Rob continue to poke at building toybox with Android's NDK, 108but it's a work in progress (<a href=http://lists.landley.net/pipermail/toybox-landley.net/2016-December/008767.html>thread</a>). Various changes 109removing libcutils dependencies and adding an selinux dependency to getprop 110are fallout from this.</p> 111 112<p>Cross-compiling from Macs needs to use "gsed" instead of apple's 113version, so teach the build to use that name if it exists in the $PATH. 114If you try to build without running config first, you should get better 115error reporting now. Added a workaround for Centos' broken "which" command 116producing output when it _can't_ find a name in the $PATH.</p> 117 118<p><u>Library</u>: 119The new dirtree flag DIRTREE_PROC skips non-numeric entries so things 120like ps and top can scan /proc more efficiently.</p> 121 122<a name="21-10-2016" /><a href="#21-10-2016"><hr><h2><b>October 21, 2016</b></h2></a> 123<blockquote><p>Probability factor of one to one.

A new toys/net directory was added, moving ifconfig, netcat, 144netstat, rfkill, and tunctl there so far.</p> 145 146<p><b>Upgrades</b>: All commands now parse --version when they understand 147--help, but "true" and "false" should now ignore their arguments entirely. 148We taught stat to handle "%12x" and "%.12x" printf-style escapes, which 149apparently other versions do. The ifconfig output now shows the interface's 150device driver. Added patch -d and --dry-run, wc can now do -cm together, 151find has a NOP -noleaf so scripts that use that don't break, add -c to md5sum 152and sha1sum. Elliott taught ps to treat extra aguments as additional -p 153pids, implemented xxd -s, did a number of upgrades to file (added -HL, 154support for ar files, improved ELF support to report android API level 155and stripped/not stripped and it no longer prints a guessed build ID type). 156Elliott also added optional build-time support for using openssl's 157assembly-optimized md5sum/sha1sum implementations (leading to a new 158<a href=design.html>design</a> policy on shared libraries).</p> 159 160<p><b>Bugfixes</b>: Too many fixes to "ps" and "touch" to list, from both 161Elliott and Rob. Rob taught sed to handle s/[[:space:]/]// type sequences 162properly, switched grep to a better 163workaround for <a href=https://sourceware.org/bugzilla/show_bug.cgi?id=17829>glibc bug 17829</a>, made sed -i preserve ownership when run as root, 164made du max out at 2 terabytes instead of 2 gigabytes on 32-bit systems 165(it was always designed to, but was missing a typecast), 166fixed the option parsing infrastructure (config options that remove command 167line options got the placeholders wrong), fix to printf for printing 168octal digits and handling the (posix-mandated) difference between %b and 169non-%b octal output, reading from "-" no longer closes stdin when done, 170netcat -L works with nommu (although it may need more portability work), 171and you can now "make test_scankey" if you want to. Several commands 172(stat, makedeves, chgrp, cp, find) handled user name lookup failure badly 173(stat was segfaulting if you interrogated a file belonging to a nonexistent 174user, "chown 12345 file" errored out if you didn't have that user 175in /etc/passwd... now they should all print/accept the number when 176appropriate). "LC_ALL=C ls -Cs --color" produces the same output 177as other versions (two spaces padding, -k hardwired on).<p> 178 179<p>Kyungsik Lee fixed a bug 180in cp (readlink() doesn't actually null terminate the string it reads in), 181Elliott Hughes made pgrep/pkill return success/failure, fixed trailing 182whitespace in netstat, fixed a SMACK symbol conflict due to linux/xattr.h 183changing, fixed ls -sh, and added a lot of 184stuff to the <a href=roadmap.html>roadmap page</a>. 185Izabera pointed out cmp -l and -s can't be selected at the same time, 186that timeout was never actually checking -v, that ls should default to -q 187when output is to a tty, and that "file -" would sometimes try to open "-" 188instead of stdin. 189Usischev Yury pointed out a use after free error, and that id shouldn't 190call exit() directly. Matthias Urhahn pointed out that stat(2) returns 191hardwired 512-byte units, so stat.c was wrong. David Hedges pointed out 192that route could only handle 10 character interface names when the kernel 193can do 15 (it's still in pending for a reason, but fixed). Evgenii 194Stepanov found and helped diagnose one of the more subtle ps bugs fixed 195this time around.</p> 196 197<p>Calling "make test_blah" no longer causes make to error out if the last 198test fails (and thus returns a nonzero error code). 199Building single commands and the multiplexer used to require a "make clean" 200between them (because they had different config files both of which were older 201than generated/config.h so it didn't get rebuilt; now it just always 202rebuilds it).</p> 203 204<p>The defconfig build is now slightly less broken on older centos versions 205(although <a href=http://lists.landley.net/pipermail/toybox-landley.net/2016-September/008664.html>the consensus</a> is that Centos is just generally broken).<p> 206 207<p>Several commands were over-using xprintf(), which flushes its output 208to check for error (something you only need to do maybe once per line, 209and even then maybe only in loops because xexit() flushes and checks 210ferror() for you and adjusts the exit code if we wrote stuff to stdout 211that couldn't be printed). Lots of little flushes are inefficient, 212so most things can use normal printf(). (Retransmission 213of short writes is presumably libc's problem since it's buffering the 214output and all.)</p> 215 216<p><b>Library:</b> 217New library functions readlink0() and readlinkat0() which properly null 218terminates the symlink value (which the stock libc function inexplicably 219doesn't). 220The new do_lines() function interates reading lines from a filehandle 221and calling a function on each line. 222New function pollinate() factoring out netcat's poll() loop so things 223like telnet can use it. 224New functions getusername() and getgroupname() return a 225char * given a uid/gid (and return a string representation of the number 226if the lookup fails), and xgetpwnamid/xgetgrnamid were renamed to 227xgetuid/xgetgid and now return an integer instead of a struct (also helping 228handle lookup failures, you can still return the uid/get for "12345").</p> 229 230<p>Switched atolx() to use long long internally. 231Renamed xopen() to xopen_stdio() and made a new xopen() that never returns 232stdin, stdout, or stderr (duping /dev/null into the filehandles as necessary). 233New function xopenro() opens a file read only with one less argument, and 234understands that "-" means stdin. New flag WARN_ONLY tells these functions 235to just print a warning on failure, and return -1 instead of exiting. 236Misc new functions like openro() which defaults to the WARN_ONLY behavior 237and notstdio() which dup()s a filehandle up beyond stdin/out/err backfilling 238with /dev/null as necessary. The WARN_ONLY flag let us remove the failok 239argument from loopfiles().</p> 240 241<p>New TOYFLAG_NOHELP disables --help processing (which "true" and "false" 242should not do).</b> 243 244<p>The test suite now has NOSPACE=1 to ignore whitespace (using diff -b to 245check results), which helps TEST_HOST pass the same tests as toybox. 246Fixes to chattr and date tests. It also has a new variable $C with the 247absolute path to the command being tested (bypassing shell builtins), 248and a function testcmd() which is just like testing() except it prepends 249the command name ($C) to the test command line as well as the test 250description.</p> 251 252<a name="02-06-2016" /><a href="#02-06-2016"><hr><h2><b>June 2, 2016</b></h2></a> 253<blockquote><p>When the 'Drink' button is pressed it makes an instant but 254highly detailed examination of the subject's taste buds, a spectroscopic 255analysis of the subject's metabolism, and then sends tiny experimental 256signals down the neural pathways to the taste centres of the subject's 257brain to see what is likely to be well received.

In pending, Elliott Hughes implemented 274file. and Lipi Lee implemented a simple wget. (Pending also had minor 275cleanups to more and lsof, but no promotions this time around.)</p> 276 277<h2>New Options</h2> 278<p>Izabera implemented env -u, suggested adding seq -w, made factor 279use full unsigned 64 bit math even on 32 bit platforms, pointed out base64 280-w0 should disable wrapping, and sped up wc -c. 281Elliott Hughes added mount -o relatime, xxd -p -r, and od -w. 282Sameer Pradhan (or possibly Bilal Qureshi) suggested adding stat -tL -c %m%t%T. 283Tom Cherry added getprop -Z. Paul Barker added hostname -b and -F. 284Rob added ls -b, made ls -q work with utf8, 285made sed -f - read from stdin, and added top -O (like ps -O).</p> 286 287<p>Elliott and Rob <b>added Thread support to ps and top</b>, 288with -o TID, TNAME. We also added -o PCY (android scheduling policy), 289-o BIT (process is 32 or 64 bit), and -o TNAME now shows the parent 290command name for threads.</p> 291 292<h2>Documentation</h2> 293 294<p>Rob added the sed invocations to convert tabs/spaces and back to 295design.html. Isaac Dunham updated hexedit's help text. 296Jakob Flierl pointed out a broken URL in the README.</p> 297 298<p>Rob also redid the naming scheme of sed's pattern manipulation code to 299remove the gratuitous references to Roger Zelazny's "Amber" series, since it 300was confusing people.</p> 301 302<h2>Bugfixes</h2> 303 304<p>Grep -H and -n should now work properly with -ABC. Andy Chu pointed out an 305out of bounds access for zero length lines in rev, fixed a buffer overflow 306in diff -r, and fixed operator precedence in expr (although Rob is rewriting 307chunks of expr so toysh can use its plumbing for $(( )) ). 308Patrick Ohly fixed the too-aggressive suid permission dropping logic. 309Josh Gao fixed a segfault when find -iname got no argument, and 310made tail -f work right with just one file argument. 311Tom Marshall cleaned up tar's long filename support and improved 312the tar tests, and reported another find bug (with -iname -o -iname not 313tracking copy lifetimes properly) that got fixed.</p> 314 315<p>Elliott Hughes fixed wc -c to not trust zero length files to actually be 316zero length (/proc does that), fixed "mount -o rw,remount /system" on 317Android, removed trailing spaces on ps -o cmdline, fixed pkill -9 and 318the corresponding tests, made "insmod -" work, fixed top -b and tail -NUM, 319pointed out that ps shouldn't trim numeric fields for display size limits, 320and added some more 321explicit "sort" calls to make pipelines so build tempfiles are easier to cache. 322Rob <a href=https://github.com/landley/toybox/commit/32b3587af261>fixed an insane sed thing</a> the perl 5.22 build was doing. 323Fixed mount -o to properly pass in leftover string data, and 324<a href=http://lists.landley.net/pipermail/toybox-landley.net/2016-March/004790.html>documented how to use toybox to mount nfs</a> (warning: kernel patch 325to fix some bitrot in the kernel NFS driver's string parsing attached 326to that message).</p> 327 328<p>George Burgess IV corrected some variable types in traceroute. 329Base64 now wraps == properly. Fixed two bzcat segfaults reported by 330John Regehr. Andy Chu found a segfault in "sed -e 'c\'" with no trailing 331line, and implemented mv -n and cp -n. The cyanogenmod guys pointed out that 332cp -a shouldn't complain if a non-root user can't chown, and we added 333the output path to cp -r error messages while we were there (before was just 334the filename).</p> 335 336<p>Samuel Holland fixed blkid's handling of vfat labels, and 337fixed a segfault when basename was passed an empty string and an empty 338suffix. Davis Mosenkovs fixed touch -t seconds parsing. 339Rob fixed a bunzip bug reported by John Regehr (the bad CRC 340error message was printing a NUL argument).</p> 341 342<p>Not all of the commands build standalone, but more of them do now; 343scripts/single.sh can now build a "mv" that isn't actually "cp". 344The dependencies are more granualr, so "make top; make ps" no longer 345produces a broken ps that ignores -A (because ps.o wasn't getting rebuilt 346even though top had the FLAG macros for -A zeroed).</p> 347 348<h2>Build</h2> 349<p>Rob added a <b>warning when building commands out of 350pending</b>. (The pending directory is full of code that hasn't been 351properly vetted. Use at your own risk.)</p> 352 353<p><b>New build targets let you build individual commands by name</b>, ala 354"make ls cat ps", and you can run the test suite for each standalone 355command with "make test_ls" and such. 356"make list" shows all such standalone commands in defconfig, and 357"make list_pending" shows unfinished commands from toys/pending 358("make list list_pending" shows both together). "make clean" now deletes 359these filenames at the top level, and the corresponding unstripped files 360live in the directory generated/unstripped.</p> 361 362<p>Nicholas Boichat suggested switching make.sh to use $! for process 363enumeration during parallel builds (which is both more efficient and more 364portable), and suggested shell builtin replacements for wc/awk/sed so the 365build loop has fewer forks now.</p> 366 367<p>Lots of work on the test suite, much of it due to Andy Chu. It now 368consistently prints the name of the command being tested at the start of each 369test (and the common infrastructure does that, not each individual test), and 370"make tests" actually runs all the available tests now. 371Seperated pgrep and pkill tests, split lsattr/chattr, added fstype and base64 372tests. The "tests/files" directory now collects files for tests to 373use, with blkid, bzcat, and utf8 subdirectories: the $FILES variable 374gives a path to it, so "$FILES/blkid/ext2.bz2" and so on. 375The testsuite now has test files with 3 different types of "not utf8 output" 376sequences that require escaping, plus some combining character torture 377tests, direction reversals, and so on.</p> 378 379<p>Added dependencies on TOYBOX_FORK to various pending commands that need 380nommu conversion (which should fix the allyesconfig build).</p> 381 382<p>Static builds with selinux should work again.</p> 383 384<h2>Library</h2> 385 386<p>New bufgetgrgid() and bufgetpwuid() functions cache previous lookup info 387rather than repeatedly traversing /etc/passwd and /etc/group (which is slow). 388Added xpipe() to lib to catch pipe creation failure. 389The HELP_ macros generated by config2help.c now use a capital prefix 390to avoid collicing with help_exit() and such.</p> 391 392<p>The dirtree infrastructure got a cleanup pass in preparation for adding 393infinite recursion depth support (needed by rm -r), updated the 394<a href=code.html#ib_dirtree>documentation</a> to describe the new 395semantics (removing dirtree_start() and adding dirtree_flagread()). 396Now dirtree_recurse() takes the new dirfd as an argument.</p> 397 398<p>Split out _xexit() from xexit() and let sigatexit() set multiple 399callbacks.</p> 400 401<p>For years the man pages have said to #include <sys/types.h> to get 402major/minor/makedev but now that glibc 403<a href=https://sourceware.org/ml/libc-alpha/2015-11/msg00253.html>has vowed 404to break existing programs</a> and replace it with another nonstandard header 405not in posix or lsb, we added our own functions to lib/ to do the transform 406ourselves (based on what the kernel actually expects).</p> 407 408<h2>Portability</h2> 409 410<p>Debian unstable started needing an extra header #include for some reason, and 411although printf("%.*s", INT_MAX, s) worked fine on Ubuntu 12.04 it 412didn't on 14.04, so added a workaround for that. Typecast a printf because 413wchar_t isn't a rigidly defined size. RLIMIT_RTTIME was 414added to the kernel in 2008 but you can't expect uClibc to have noticed yet, 415nor did it #define MS_RELATIME (added in 2006), or prlimit (2010)... 416(Given the improvements in musl and bionic, uClibc support may be dropped 417in a future release.) Given that the xattr functions were added during 418linux 2.5, we can #include its header unconditionally.</p> 419 420<p>Renamed basename_r() to something else to avoid conflicting with freebsd's 421libc, and both scripts/install.h and scripts/config2help.c no longer include 422toys.h (to make cross-compiling from systems we don't run on easier).</p> 423 424<p>Debian bug 635570 did something unspeakably nonportable, depending on 425"sed -e 'a\'" (with no next line of the pattern, so an unterminated 426continuation) to add a newline to the last line of input if and only if 427that last line of the input didn't have a newline, and to take no other 428action. This is well into "depending on a bug" territory, but we implemented 429it because otherwise Debian's install broke.

Fixed sort -f and added test cases. 485Assume 80 columns in "ls -m | cat", ls -L is no longer backwards, 486and ls of files with no paths no longer uses an uninitialized (zero) dirfd. 487Several bugfixes 488to find (Gilad Arnold fixed -perm, Daniel K. Levy fixed "find . -exec echo {}", 489and while we're there I fixed find --prune, made "find . -execdir 490echo {} + -execdir ls {} +" work, and ripped out the environment size 491measuring code that checked for a 128k limit removed back in linux 2.6.22). 492Elliott Hughes fixed the date command's parsing of 4 digit 493years and documented the %s escape, fixed hwclock -u, and pointed out 494that runcon needs to exec to do its job (not recursively call another 495command_main() in the same process). Tom Marshall reported that blkid was 496handling ext2 wrong. Mike Moreton corrected cpio extraction's uid and gid 497values, and added a --no-preserve-owner option. Fixed the SUID permission 498dropping logic (which was a bit over-zealous, preventing some commands from 499running at all).</p> 500 501<p>I'm told that debian-testing broke its libc so the nsenter build breaks, 502but my attempts to install the debian-testing network cd image under 503qemu keep breaking.

Isaac Dunham upgraded mdev, 642reboot, init, login, and modprobe, and fixed a distro-specific build break in 643scripts/mkflags.h. Elliott Hughes and Lipi Lee made netstat -p handle 644command lines longer than 21 characters, and Elliott fixed netstat -e and 645some build warnings. Yeongdeok Suh fixed a warning in dhcpd. 646I started cleanup on pgrep/pkill.</p> 647 648<h3>Command updates, bugfixes, and infrastructure</h3> 649 650<p>The multiplexer's "command not found" error exit is now 127, so now you can't 651distinguish between a command not being found in the multiplexer and 652the multiplexer itself not being found by the shell, because people wanted 653that for some reason.</p> 654 655<p>Elliott Hughes made date reject invalid dates rather 656than set the clock to something weird (setting the clock 100 years into the 657future makes most Linux desktops surprisingly unhappy, and ntpdate won't fix it 658either), fixed several ls -l display issues (user/group field ordering, 659make user/group/lsmcontext left aligned), did the aforementioned 660extensive work on human readable number output, fixed ionice's default 661class, fixed a mv overwrite bug, made df's columns auto-size, added 662--ppid and -Z to ps, and teamed up with Daniel K. Levy to fix 663a segfault in find's handling of -newer -group or -user.</p> 664 665<p>Hyejin Kim added stat -c %T support. Colin Cross worked 666on vmstat fixing 667a header printing bug and calculating the bi and bo columns in the right 668units. Isabella Parakiss reported that sed -e "/x/c\" -e "y" added an extra 669newline and that grep -w '\(x\)\1' didn't work, both now fixed. 670Alistair Strachan fixed several problems with switch_root. Kylie McClain 671pointed out env should be able to clear variables via NAME= syntax. 672Dima Krasner added support for running blkid without a partition (so it shows 673all partitions).

Kylie McClain 678pointed out env should be able to clear variables via NAME= syntax. 679Dima Krasner added support for running blkid without a partition (so it shows 680all partitions). Hyejin Kim sent in a bunch of static analysis bug reports.</p> 681 682<p>Two large thinko fixes in oneit: -3 was always enabled (which would 683eventually block if the child never read the exiting PID numbers from its file 684descriptor #3 until the pipe filled up), and the signal handlers weren't 685set up right (for requesting semi-graceful halt/poweroff/reboot). 686Calling install without a mode is now 0755, and install -g 0 no longer clashes 687with cp --preserve. Better error message for ls -r on unreadable 688directories, and ls -Z now uses O_PATH (with the /proc/self/fd/%d 689workaround for kernel stupidity as necessary).</p> 690 691<p>Date now understands @unixtime[.fraction] and uses -D for 692the set-side format (matching busybox's extension for this). The seq -f 693string now checks that it's got exactly one %f escape with the correct 694attributes (and a whole bunch of test cases for it). Fixed a bug 695in od that screwed up the position indicator on arm and mips. 696In stat the d/h units moved from %d %D to the default string. 697And patch can now correctly apply hunks with trailing context to the start of 698the file.</p> 699 700<p>The prompt argument moved out of yesno() (the caller can print the prompt 701themselves). Replaced toys.exithelp with help_exit(). Added new 702XVFORK() macro, and xpopen_both() calls /proc/self/exe when passed 703a NULL argv (see cpio -p for example usage). Replaced toys.recurse 704with toys.stacktop so the recurse or re-exec decision is now based 705on bytes of stack space used. Marked a bunch of command-local functions 706static.</p> 707 708<p>New additions to lib/ include strlower(), xconnect(), and the 709aforementioned help_exit(). 710The testsuite now has some infrastructure tests based on "example" 711commands such as toys/examples/test_human_readable.c. 712The login command finally got a long-overdue cleanup (it's one of the 713commands that predate the "pending" directory but were part of the reason 714for it). Hexedit had an 715uninitialized variable (of course gcc didn't spot it, it was too busy 716warning about "may be used uninitialized but never actually is" variables).</p> 717 718<p>Tweaked makefile so 719"make CROSS_COMPILE=prefix-" (as well as "CROSS_COMPILE=prefix- make", 720which still works). Toybox is now installed chmod -w so broken installers 721(like the bunzip2 package's) that try to overwrite existing binaries won't 722knock out the whole of toybox. 723GCC 5.2.0 stopped being able to compile Linux 2.6.12's kconfig, but 724we added a workaround. You can now build uptime without utmpx.h. 725Alejandro Joya pointed out that enabling smack required smack on the host 726as well as target when cross compiling, which is now fixed.</p> 727 728<p>Note: toybox can autodetect nommu support when building with a uClibc 729toolchain such as <a href=http://landley.net/aboriginal/downloads/binaries/old/1.4.3/cross-compiler-sh2eb.tar.gz>the one from Aboriginal Linux</a>, 730but <a href=http://github.com/richfelker/musl-cross-make>with musl-libc</a> 731you'll have to enable CONFIG_TOYBOX_MUSL_NOMMU_IS_BROKEN to work around the 732fact they provide a non-functional fork() implementation that always returns 733-ENOSYS, to prevent you from compile-time probing for nommu support when 734cross-compiling. Unfortunately "preventing you from probing" seems to be 735an explicit policy with musl, they also don't provide an "#ifdef __MUSL__" 736because their library is perfect and you're only ever allowed to work around 737other people's bugs, not theirs.

Also added description of ";" 849to make --longopts take an optional =value part, and more about TOYBOX_DEBUG 850to check NEWTOY() option strings (otherwise a bad option string makes 851lib/args.c obviously segfault, but doesn't explain why).</p> 852 853<p>Added a "Why 0BSD?" section to license.html when submitting zero clause bsd 854to SPDX (according to the pending license spreadsheet, it's been approved for 855SPDX 2.2).</p> 856 857<p>The old list of commands needing cleanup but not in pending was 858removed from toys/pending/README and instead the issues were added 859as TODO comments in the individual commands.</p> 860 861<p><b>Bugfixes:</b> 862Fixed mount -a segfaulting without -O (reported by Janus Troelsen), 863and made it try a "become rw" ioctl() on the block device before falling 864back to mounting read only (because Android expects that). 865Fixed printf -- and printf ---. Lots of tweaks to ls -l spacing with 866different options. Make touch -d and -t actually set time when you don't 867specify nanoseconds. 868Fixed a subtle bug where recursive calls (toybox commands that run other 869toybox commands) weren't resetting all their state. (This manifested as 870a "no }" error from "find | xargs sed", but could cause other problems.) 871And David Halls reported another sed bug trying to compile libiconv (which 872left extra \ at the start of lines in a generated shell script, breaking 873the build). Output an error message for "cat /mnt".</p> 874 875<p>Kylie McClain reported that mktemp broke when $TMPDIR was set to an empty 876string (which is not the same as unset), that install/find didn't support 877numeric uid/gids, and that sort -z affects both input and output. 878Isabella Parakiss fixed a printf.c bug. 879David Halls fixed bugs in install -D and find -exec. Samuel Holland 880fixed unshare -r. Hyejin Kim fixed makedevs with a count of 1, fold -w 881range checking, an error path in scripts/mkflags.c, added -i to dhcpd, 882and stopped su from prompting the root user for the new user's password. 883Jan Cybulski spotted wrong indentation when combining ls -s and -i with -C and 884-x. José Bollo fixed stat %G. Sameer Pradhan fixed a bug in mkfifo -Z.</p> 885 886<p>Elliott Hughes asked for a default SIGPIPE handler to disable 887the signal handler bionic's dynamic loader installs (yes really). Still not 888100% sure what the correct behavior is there. (Posix is 889(<a href=http://permalink.gmane.org/gmane.comp.standards.posix.austin.general/10915>actively unhelpful</a>, but at least they're taking 890<a href=http://austingroupbugs.net/view.php?id=789#c1976>years to 891make up their mind</a>. Elliott also sent patches to fix a typo in 892useradd.test, add missing arguments to error_exit() calls and clean up 893printf() format strings, fix an off by one error in human_readable(), 894fix dmesg -c error reporting, fix a segfault in comma_scan where the option 895was the last item in optlist (triggered by mount -o ro,remount), fix 896hwclock -w, made ifconfig print lowercase MAC addresses (it was bothering 897him), and make terminal_size() read the right environment variable 898(LINES, not ROWS). And he suggested the test suite notice high command exit 899values (corresponding to segfault or other signals).</p> 900 901<p>People are apparently using toys/pending commands, despite the police tape 902and flashing lights, so added louder warnings to toys/pending/README. 903Elliott Hughes fixed various problems with tar, dd, more, and top. 904Hyejin Kim cleaned up syslogd and dumpleases. Isaac Dunham added hotplug 905support to mdev. Yeongdeok Suh added RFC-3315 ipv6 support to dhcpd.</p> 906 907<p>I rewrote ps.c from scratch (in pending), but it's not ready for real use 908yet.</p> 909 910<p><b>Portability:</b> 911On the portability front Bernhard Rosenkranzer fixed a problem where the 912menuconfig code wouldn't compile in C99 mode. (This led to me documenting 913the craptacular nature of kconfig in a README, and the plan to replace it 914sometime before 1.0.) Some extra flags to shut up overzealous llvm warnings 915were added (and have to be probed for because gcc complains about 916arguments it doesn't recognize even when they switch stuff _off_ using 917a standard syntax). Don't depend on malloc(0) to return non-null in ls. 918David Halls fixed some mac/ios portability issues, 919implying somebody's built at least part of toybox on a mac.</p> 920 921<p>Added basename_r() to lib/lib.c because the posix semantics for basename() 922are stupid but what the gnu guys did to it was appalling. 923Turns out bionic already had a basename_r(), but posix still doesn't. 924Fixed it up in portability.h, but this 925could break more stuff in future. (Correct fix is to lobby posix to add it, 926which would probably take about 15 years...)</p> 927 928<p><b>Infrastructure:</b> 929The build now checks $LDFLAGS for linker-only flags, and allows the strip 930command to fail (binflt toolchains provide a strip that doesn't work). 931Since time.c uses floating point, added TOYBOX_FLOAT dependency in config.</p> 932 933<p>There's a lib/lsm.h defining varous inline functions for linux 934security modules stuff, if (lsm_enabled()) should turn into a compile-time 935constant 0 and let code drop out when TOYBOX_LSM_NONE selected, but 936testing against CFG_TOYBOX_LSM_NONE or derived symbols is still useful 937becuase when it _is_ enabled the probe turns into a system call you 938don't want to repeat too much.</p> 939 940<p>Switched a bunch of commands from signal() to xsignal(). Factored out 941xgetgrnamid() and xgetpwnamid() into xwrap.c. Make time.c depend on 942TOYBOX_FLOAT (since it always uses float so shouldn't be available on 943build targets without even software float). Added readfileat() to lib/lib.c.</p> 944 945<p>The dirtree infrastructure now passes in full flags for the old symlink 946field, and the new DIRTREE_SHUTUP flag disables warnings if a file vanishes 947out from under you during traverse. New dirtree_start() wrapper to 948create dirtree root with only two arguments.</p> 949 950<p>The not-curses infrastructure introduced by hexedit mostly moved to 951lib/interestingtimes.c.</p> 952 953<a name="asterisk" /> 954<a href="#asterisk_back" />Asterisk:</a> such when 955Tim contacted me (my blog says a couple days before nov 13, 2011, I.E. 95611/11/11 not some specific day 2 months later) to ask if I wanted to work 957on a new project he was proposing called 958<a href=http://www.elinux.org/Busybox_replacement_project>BentoBox</a> 959(because I used to do busybox, he'd forgotten toybox existed 960until I brought it up). And don't ask me what "focuses not on compatibility 961with its GNU counterparts" means when CP_MORE adds 7 non-posix options 962and toys/other has 84 commands in neither posix nor LSB. I think they're 963struggling to explain the difference having dismissed "licensing" as being 964the reason it started up again after a long hiatus? The reason I don't think 965GNU is special is there are a half-dozen other independent 966implementations of the same unix command tools out there (AT&T, 967BSD, Coherent, Minix, plan 9, busybox, toybox, and several more analyzed in 968the <a href=roadmap.html>roadmap</a>, and that's ignoring the implementations 969written for DOS or in assembly over the years). But I do care what 970Linux From Scratch expects, and if it's 971<a href=http://archive.linuxfromscratch.org/lfs-museum/7.6/LFS-BOOK-7.6-NOCHUNKS.html#ch-tools-gcc-pass1>calling mv -v</a> 972then I impelement mv -v 973even if <a href=http://landley.net/toybox/roadmap.html>posix hasn't got 974it</a>. And I don't know why "gnu counterparts" would describe this when 975util-linux isn't a gnu package, nor are info-zip, e2fsprogs, kmod, less, 976procps, shadow, sysklogd, vim, zlib, sudo, dhcpcd...</p> 977 978<a name="05-04-2015" /><a href="#05-04-2015"><hr><h2><b>April 5, 2015</b></h2></a> 979<p>Since <a href=https://android.googlesource.com/platform/external/toybox/>android</a> and 980<a href=https://git.tizen.org/cgit/platform/upstream/toybox.git>tizen</a> 981and <a href=https://github.com/kraj/meta-musl/tree/master/recipes-core/toybox>openembedded</a> 982and <a href=https://packages.gentoo.org/package/sys-apps/toybox>gentoo</a> 983and so on have all been using Georgi Chorbadzhiyski's git mirror rather 984than the mercurial repository, I bit the bullet and switched the project's repo 985<a href=https://github.com/landley/toybox>to git</a>.

On toybox's end this 1004involved a lot of fixups to portability.[ch] and fixes to over a dozen 1005commands, plus several new ones. Other portability fixes included working 1006with buildroot's uclibc fork and building for nommu targets.</p> 1007 1008<p>The new "make change" target builds each toybox command as a standalone 1009binary. Rather a lot of commands that didn't build by themselves (mv depending 1010on cp and so on) were hit with a large rock until they built standalone. 1011This involved rewriting bits of option parsing, more elaborate dependency 1012generation, making each command have its own config 1013symbol and main() function (even when it's just a wrapper calling another 1014command's main()), and so on. Also, some commands can't be built standalone 1015at a conceptual level: "help" describes other enabled commands and "sh" 1016has a number of bulitin commands (cd, exit, set) that require the 1017multiplexer infrastructure, so "make change" filters them out.</p> 1018 1019<p>The mailing list's web archive is still screwed up. Dreamhost has 1020been trying to fix it since approximately September. There are 1021<a href=http://www.mail-archive.com/toybox@lists.landley.net/>two</a> 1022<a href=http://news.gmane.org/gmane.linux.toybox>other</a> less broken 1023archives, but neither has quite the same UI as mailman.</p> 1024 1025<h3>Bugfixes and tweaks</h3> 1026 1027<p>Cynt Rynt sent in tests for ifconfig, 1028Robert Thompson taught factor to accept whitespace separated arguments, 1029Hyejin Kim pointed out that some of mktemp's longopts were attached to 1030the wrong short options, 1031Luis Felipe Strano Moraes fixed a wrong free() call in bootchartd in pending. 1032Patches from Ashwini Sharma to make "df /dev/node" work, prevent du from 1033looping endlessly following symlinks, and to make expr.c 1034(in pending) understand == and regex matches. (Speaking of expr, it gets 1035priority groupings wrong but the bug was actually in the posix spec's 1036HTML conversion. They fixed the posix spec upstream for us. Still need 1037to fix the expr code, but it's in pending for a reason...)</p> 1038 1039<p>Some commands grew new option flags, such as cp --remove-destination 1040and touch -h.</p> 1041 1042<p>The parallel build has better error reporting now. When toybox needs to 1043re-exec itself to regain suid root permissions and hasn't got the suid bit, 1044it now gives the right error message ("not root" instead of "no such command"). 1045 1046<p>Added a test to "mount" to not mount the same device/directory combination 1047over itself (the OS catches this for block devices, but not for tmpfs). 1048Make blkid distinguish ext3 from ext4. Added catv back into cat (because 1049the Android guys wanted it, and they have historical usage on their side, 1050so...). Handle nanoseconds in touch.</p> 1051 1052<p>Fixed a segfault when CP_MORE was disabled (the resulting option flag list 1053no longer defined -d but still had it in option groups at the end). 1054Workaround for glibc redefining dirname() and basename() to random non-posix 1055semantics because gnu. (They could have created dirname_r() but didn't want 1056to.)</p> 1057 1058<p>Fix an ifconfig test that was preventing assigning an ipv4 address to 1059interface aliases. Several cleanup passes on hwclock but not quite 1060promoted out of pending yet.<p> 1061 1062<p>Fixed a wrong error message in rm (if you had a chmod 000 directory and 1063did rm -r on it without -f, after the prompt it would complain it was a 1064directory, which was not the problem).</p> 1065 1066<p>The gzip compression code now does "store only" output to stdout, for 1067what that's worth.</p> 1068 1069<p>Cleanup mountpoint and expand, and remove them from toys/pending/README 1070(a list of commands that predate the toys/pending directory but needed 1071another pass).</p> 1072 1073<h3>Library and infrastructure:</h3> 1074 1075<p>Reworked the option parsing infrastructure so more commands build 1076standalone (via scripts/single.sh or "make change"). The option flag bit 1077values are no longer packed, it leaves spaces where currently disabled 1078flags go, and you can #define FORCE_FLAGS so disabled flags aren't zeroed. 1079This allows multiple commands to more easily share infrastructure, even if 1080your current flag context is for a disabled command (switched off in config), 1081you can force them to stay on and as long as the flags read the same right 1082to left they'll have the same values.</p> 1083 1084<p>We've started removing use of strncpy() because it's a hugely broken 1085standard C function: the length is the maximum length to _append_, not 1086the size of the destination buffer. It memsets the remaining space it didn't 1087copy ala "memset(dest+strlen(dest), 0, len);" so 1088if you think len is the size of dest you're guaranteed to stomp memory off the 1089end). And if it runs out of space it won't null terminate because reasons. 1090(Meanwhile sprintf("%*s", len, str) is counting wide characters in your current 1091locale, so if you set a locale other than "C" it will also go past your 1092allocated buffer size. Whoever is maintining the C library standards is really 1093bad at strings.) 1094Instead we have xstrncat() which will error_exit() if src+dest+1 doesn't 1095fit in the buffer. (Because randomly truncating input data isn't necessarily 1096an improvement.) And there's always xmprintf().</p> 1097 1098<p>Similarly, strtol() doesn't return an error indicator on overflow, 1099you have to clear and then check errno. So new xstrtol() that cares 1100about overflow.</p> 1101 1102<p>The bionic and musl guys agree faccessat(AT_SYMLINK_NOFOLLOW) is not 1103supported, so stop using it.</p> 1104 1105<p>Fixed toy_exec() to detect when argc is in optargs, so we don't 1106need a separate xexec_optargs().</p> 1107 1108<a name="18-02-2015" /><a href="#18-02-2015"><hr><h2><b>February 18, 2015</b></h2></a> 1109<p>Dreamhost continues to be unable to make mailing list archives work, so 1110here's <a href=http://www.mail-archive.com/toybox@lists.landley.net/>another 1111list archive</a> with a less awkward interface than gmane.</p> 1112 1113<p>(Neither gives you the convenient historical monthly views of mailman, 1114but I still have hopes dreamhost will someday figure out what they're doing 1115wrong.

Last month they did a 1116<a href=http://www.dreamhoststatus.com/2015/01/14/discussion-list-hardware-maintenance/>hardware upgrade to fix a software problem</a>, and the stale 1117data loads much faster now, so that's something.)</p> 1118 1119<p>Update (Feb 19): the archive started updating again, by discarding 1120all the pending data. So there are now _two_ giant holes in Dreamhost's 1121web archive, from Dec 15-Jan 3, and then another hole from Jan 16-Feb 18. 1122The relevant messages are in both of the other archives.

Cynt Rynt spotted an 1179unnecessary assignment in lib/password.c.</p> 1180 1181<p>Ashwini Sharma's team was as busy as usual, submitting tr, crontab, and 1182ipcrm, and hwclock to pending, more features to the pending ip.c, and a 1183pile of bugfixes (to chgrp, killall, ifconfig, insmod, 1184losetup, comm, cp, id, xwrap, netcat, modprobe, nohup...) mostly found by 1185static analysis. (These fixes are mostly to seldom-used codepaths like the 1186TOYBOX_FREE config option, but test coverage is always appreciated.) Ashwini 1187also suggested upgrading ln -f to leave the original target alone if link 1188creation fails, and reported that mv -f and -i weren't implemented (now fixed).</p> 1189 1190<p>New config option: TOYBOX_NORECURSE prevents xexec() from making internal 1191function calls (for nommu systems with a finite stack).</p> 1192 1193<p>The "toybox" multiplexer command no longer adds a trailing space to each 1194line of command names, so things like "./toybox | tr ' \n' '|'" to create 1195a grep pattern snippet are easier to do. (Why you'd want to is your business, 1196but the output is tidier now.)</p> 1197 1198<h3>Infrastructure</h3> 1199 1200<p>Isaac Dunham added Android support to portability.h, including compile 1201probes for functions missing from bionic-libc, and annotated the commands that 1202use those functions. We haven't really tested building against bionic, 1203but in theory it's possible now.</p> 1204 1205<p>Running the test suite now color codes the PASS/SKIP/FAIL notifications 1206if output is to a tty. (And in case you missed it last time, VERBOSE=fail 1207to stop at the first failure is really useful.)</p> 1208 1209<p>In loopfiles_rw() use O_CLOEXEC instead of O_RDONLY to request the loop 1210function close filehandles for us.

(Export the environment variable CPUS to pick a specific number.) 1247Other build changes: split out $LDOPTIMIZE because old compilers complain 1248about linker options passed with -c, and the entire "generated" directory now 1249gets deleted by clean (the README that was in there got merged into code.html).</p> 1250 1251<p><b>Standalone builds</b></p> 1252 1253<p>The standalone build infrastructure (scripts/single.sh) got upgraded to 1254build more commands as standalone executables. In make.sh the source file 1255selection uses a regex to find the source files with the NEWTOY/OLDTOY macro 1256for the command. It enables each command's 1257sub-options (so CP has CP_MORE), enables I18N and FLOAT support to build 1258full-featured commands, and includes --help text (at least when 1259the command doesn't use another command's help). The OLDTOY() macro 1260now produces (redundant) function prototypes so you can build an OLDTOY 1261without the NEWTOY</p> 1262 1263<p>It doesn't quite have complete coverage yet, the defconfig entries that 1264aren't building standalone yet are:</p> 1265 1266<blockquote><p>chown, egrep, fgrep, fstype, halt, mv, nc, poweroff, unix2dos, 1267whoami</p></blockquote> 1268 1269<p>The main reason for standalone build failures is NEWTOY() or OLDTOY() 1270entries that don't have their own config symbol. Another problem is entries 1271that depend on another entry in kconfig, usually because common infrastructure 1272is using one command's flags (which the other commands copy): if that command 1273is disabled, the FLAG macros become 0 so dead code elimination can remove the 1274code. It's <a href=http://landley.net/hg/toybox/rev/1503>possible 1275to untangle</a> this, but a bit awkward. (It boils down to conflicting 1276design goals in the two contexts.)</p> 1277 1278<p>Standalone builds are used by the test suite when testing individual 1279commands. 1280 1281<p><b>Snapshot builds</b></p> 1282 1283<p>A new addition to the "generated" directory is generated/build.sh 1284containing a single compiler command line to build toybox in its current 1285configuration. Combined with the generated/*.{h,sh} files from an 1286exisiting build, this may let you build on a new system that hasn't quite 1287got enough OS bits working to run a full configureand make.</p> 1288 1289<h3>Internals</h3> 1290 1291<p>Library code: xcreate/xopen now O_CLOEXEC by default to avoid leaking 1292filehandles to child processes. DIRTREE_COMEAGAIN's second callback is now 1293done with the directory filehandle still open (new dir->again variable added 1294to distinguish first from second callback, and requesting DIRTREE_RECURSE now 1295requires passing in the specific macro value, not just a true/false). 1296Use daemon() out of libc instead of hand-rolled daemonize() in various 1297pending commands. string_to_mode() now passes through type bits so you can 1298use it to more easily modify a file's existing mode. 1299Split xpopen() into xpopen_both(), xopen(), and xrun() depending on whether 1300we want to redirect both, one, or neither of stdin/stdout.</p> 1301 1302<p>Bugfixes: Better error message when TOYBOX_SUID option can't drop priviliges 1303(which happens when you suid something _other_ than root). 1304The old pending version of nbd_client.c wasn't deleted when the 1305command was promoted (and the build would break if both were enabled), 1306toy_exec() sometimes needs to re-exec from $PATH rather than recurse 1307internally (to gain dropped root permissions or limit stack depth), 1308always call setlocale() when I18N is enabled to switch it back _off_ when 1309we run commands that expect sscanf("%n") to return bytes, 1310dirtree() had a memory leak in an error path, patch.c had some bugs in 1311error paths (didn't report problem clearly). Ashwini Sharma spotted an 1312option parsing bug where [-abc] would forget _all_ command line arguments 1313saved in the GLOBALS() block (not just the ones for options being switched 1314off), plus various minor fixes to nbd_client and cpio. 1315Lukasz Szpakowski fixed rm -f on a broken symlink (failed), and killall 1316with no arguments (segfaulted).</p> 1317 1318<p><b>Portability</b></p> 1319 1320<p>A somewhat fiddly fix to rm -rf (which needs to chmod directories to u+rwx 1321to descend into them) which hit a musl bug in faccessat() which the musl 1322maintainer refuses to fix. (He literally wants the man page changed 1323instead, despite other libcs working.) Added an #ifdef __MUSL__ section 1324to portability.h with a workaround, you may need CFLAGS=-D__MUSL__ in your 1325build if your musl build's features.h doesn't #define that. (I may do 1326a different workaround in future, but sometimes you've just got to make 1327it work so you can ship. Also, toybox grep with multiple patterns 1328requires <a href=http://landley.net/hg/aboriginal/rev/1692>a patch 1329to musl's regex engine</a>, which applies to 1.1.4 but not to the current 1330musl source control.)</p> 1331 1332<p>More portability.h fixes for uClibc too. (I don't expect that to ever have 1333another release, so locally patching around posix-2008 violations is silly).</p> 1334 1335<p><b>Change to username filtering</b></p> 1336 1337<p>Posix recommends the username creation logic filter usernames to a small 1338allowed set of characters (which even Red Hat breaks by explicitly allowing 1339"$" at the end), but this prevents UTF-8 usernames. Posix' stated logic 1340is to allow filesystems to create the user's home directory, but Linux 1341filesystems can accept any character but NUL and "/". The only characters 1342we actually _need_ to filter out are ":" (field separator in passwd), 1343newline (line separator in passwd), and "/" (directory separator in 1344filesystem).</p> 1345 1346<h3>Documentation</h3> 1347 1348<p>Web pages updated: cleanup.html documents more cleanup, code.html 1349documents more code, and about.html now capitalizes "toybox" consistently 1350(it's just a word, capitalize at start of sentence).</p> 1351 1352<p>The pending/README file now lists commands that needed review/cleanup 1353before the pending directory was added.</p> 1354 1355<h3>Test Suite</h3> 1356 1357<p>Moved out of scripts/test into top level "tests" directory, and the 1358testing.sh script is now in scripts rather than mixed into the *.test files.</p> 1359 1360<p>Johan Bergström requested VERBOSE=fail to make tests (telling it to 1361stop at the first failure), and spotted a build bug where using gnu 1362sort on the host broke in non-C locales.</p> 1363 1364<p>Divya Kothari submitted tests for chmod, link, tar, bzcat, xzcat, zcat, 1365and hostname.

(Not a show 1401stopper for incoming 1402contributions, just an explanation of some of the things I'll do to them 1403during cleanup.)

Make the "we are not root" test 1423in the init code show the help text. Posix implies that fflush() can return 1424success even when the stream's error bit is set, so call both fflush() and 1425ferror() from xprintf().</p> 1426 1427<p>Isaac Dunham pointed out that bloatcheck couldn't deal with diff 1428implementations that only implement "unified diff" format, and that some 1429diff implementations can't handle nonseekable input (I.E. reading from 1430a pipe). Bugfix so "help -a" works again. Option parsing on nohup now stops 1431at first nonoption argument. Fix segfault in "which" if PATH wasn't set, 1432which was actually a bug in lib function find_in_path(). Made rm -rf of 1433chmod 000 directories actually remove them.</p> 1434 1435<p>The build now passes the same $CFLAGS to the library probe as the final 1436build, because arch linux is so broken it provides different sets of 1437libraries for static and dynamic linking.</p> 1438 1439<p>It turns out sprintf("%.123s", str) is counting characters, not bytes, 1440so globally enabling locale support opens stack smashing vulnerabilities. 1441So there's a new TOYFLAGS_LOCALE you set in toyflags when you want the 1442setup code to setlocale().</p> 1443 1444<p><b>Upgrades:</b></p> 1445 1446<p>Isaac Dunham extended cpio to archive unreadable empty files, and I taught it 1447to set uid/gid and timestamp when extracting archives. Isaac also 1448added tests for cpio, link, and du, added lspci -i, made the pci database 1449parsing skip # comment lines, merged logname and whoami into id.</p> 1450 1451<p>Daniel Verkamp sped up md5sum about 30% with some loop unrolling, making 1452it actually smaller in the process. I added -b flags to md5sum and sha1sum 1453for "brief" output that's just the hash with no filename. (I'm aware other 1454implementations use that for MSDOS "binary" mode, and don't care.)</p> 1455 1456<p>When building standalone commands (scripts/singleconfig.sh commandname), 1457the build now switches on all the sub-options of the command so we get 1458a standalone version with all the bells and whistles enabled.</p> 1459 1460<p>Add -ds flags to date and document +FORMAT escapes. Add the shell NOP 1461command ":" as an alias for true (for toysh).</p> 1462 1463<p>Add uClibc probe for iconv() and fallocate. (The fact it didn't always 1464build against uClibc is why fallocate wasn't enabled in defconfig before.)</p> 1465 1466<p>The umount command now does an losetup -d on the device by default, so 1467we don't leak loopback devices. Bugfix to losetup so "losetup /dev/loop0 1468filename" actually works again.</p> 1469 1470<p>Divya Kothari sent in test suite entries for ls, ln, rm, mv, printf, dd, 1471and renice. Then a second round for lsattr/chattr, mount, chmod, pgrep/pkill, 1472groupadd, groupdel, and useradd. Several of these uncovered bugs, still 1473working to fix them.</p> 1474 1475<p>There are now free() functions for the predefined llist types and a 1476dlist_terminate() function to break doubly linked lists. The new 1477generic_signal() handler either sets "toys.signal" or writes a byte 1478to toys.signalfd with the signal number if signalfd isn't -1 (which it's 1479initialized to in toy_init).</p> 1480 1481<p>The option parsing logic can now detect when a double fits in a long and 1482use the more precise type for floating point arguments (the FLOAT macro 1483contains the type used). The human_readable() function now just outputs 1484decimal kilo/mega/gigabytes (so when du -u says 5.0G it means 5.0 billion 1485bytes). The build infrastructure now notices duplicate commands (so if you 1486cp toys/pending/command.c toys/other/command.c and forget to delete the 1487first one, the build break is now more informative).</p> 1488 1489<a name="20-04-2014" /><a href="#20-04-2014"><hr><h2><b>April 20, 2014</b></h2></a> 1490<blockquote><p>And to this end they built themselves a stupendous supercomputer 1491which was so amazingly intelligent that even before the data banks 1492had been connected up it had started from "I think therefore I am" and got as 1493far as the existence of rice pudding and income tax before anyone managed to 1494turn it off. - The Hitchhiker's Guide to the Galaxy.</p></blockquote> 1495 1496<p><a href=downloads/toybox-0.4.8.tar.bz2>Toybox 0.4.8</a> is based on 1497<a href=http://landley.net/hg/toybox/shortlog/1262>commit 1262</a>. And 1498about time too.</p> 1499 1500<p>The big news is that the build no longer needs python to generate help.h, 1501that's now done in C. The help text generation is also collating help text 1502from multiple options, merging command line option blocks and usage: lines. 1503There's even a new <a href=help.html>help web page</a>.</p> 1504 1505<p><b>New commands:</b> Ifconfig, cpio, and su were cleaned up the rest of the 1506way and promoted out of pending.

Kyungwan Han's team submitted modprobe and getty. 1514Vivek Bhagat submitted openvt and deacllocvt. Samuel Holland submitted fold. 1515I wrote a new inflate (zip/zlib/gzip decompression) implementation in 1516compress.c, and still need to do a corresponding deflate (compression-side) 1517and plug them into gzip and zip and so on.

Grep now has -zZ to 1526handle null terminated data, cksum grew -H for hex output. Upgraded od so the 1527fields align better when producing multiple output types. Help has -a and -h 1528options (all commands, html output). 1529Bugfix to blkid building for a 32 bit target. The date command can actually 1530set dates now. The O_NOFOLLOW compile time probe didn't work with cross 1531compiling, so it's back to an #ifdef test in portability.h. Nathan McSween 1532sent in a bugfix to od and a portability fix in the common library code. 1533Ashwini Sharma spotted a bug in pidof -o, and added verbose (-v) options 1534to mkdir and ln, and suggested killall should have an -s option and 1535allow -l to take zero arguments. Ashwini Sharma and Felix Janda upgraded 1536tftpd. Fixed dumpleases still using toynet.h after 1537that was removed. Corrected killall return code and error reporting. 1538Isacc Dunham fixed bugs all over the tree, did cleanup on a bunch of 1539pending commands (getty, ftpget, init, openvt, modprobe...), and clarified 1540find's help text. Tom Sparrow ran three different static analyzers on 1541the code, which resulted in a few cleanups. The peek()/poke() functions 1542now use "volatile" to prevent broken compiler "optimizations" to do with 1543aliasing.</p> 1544 1545<p><b>Build stuff:</b> Each FOR_xxxx macro now has a complementary CLEANUP_xxxx macro, so you 1546can put multiple commands with different command line options in the same 1547.c file, so they can share infrastructure outside of lib.

Farkas-Dyck), and sysvinit by Kyungwan Han.</p> 1645 1646<p>Some cleanup work on existing pending commands that aren't 1647ready to promote yet: I did a few more rounds on ifconfig 1648and Isaac Dunham's did several cleanups to xzcat, Felix Janda cleaned up 1649logger and syslogd...</p> 1650 1651<p>Also some cleanup work on commands that predate the pending directory, 1652but weren't quite polished when they went in, most prominently du, 1653expand, and touch.</p> 1654 1655<h3>Infrastructure</h3> 1656 1657<p>The new scripts/single.sh builds a standalone command without the 1658multiplexer, although not all commands can be built that way yet (NEWTOY yes, 1659OLDTOY no) and the space savings aren't anything to write home about. (If a 1660command needs the option parsing logic at all, it needs all of it.) If 1661you're curious, you can do:</p> 1662 1663<blockquote><pre> 1664make defconfig 1665make 1666mkdir singles 1667for i in $(./toybox) 1668do 1669 echo $i 1670 PREFIX=singles/ scripts/single.sh $i || break 1671done 1672</pre> 1673<p>(And then wait a long time and watch almost half the builds fail.)</p> 1674</blockquote> 1675 1676<p>There is now libbuf analogous to toybuf, another global 4k buffer this 1677time for use by lib/ code instead of command code.</p> 1678 1679<p>The lib directory got split up a bit, lib/pending.c contains functions 1680not yet used by anything outside of toys/pending/*, and lib/xwrap.c contains 1681functions that wrap other functions and handle failures (via error_exit). 1682This leaves lib/lib.c containing actual new functions.</p> 1683 1684<p>General improvements and bug fixes to argument parsing. The [-abc] exclude 1685logic should now clear arguments slots when disabling options. Bare --longopts 1686should work now and be able to report errors using their name, the new ; 1687option allows optional arguments to longopts only suppliable with = (I.E. 1688--color and --color=auto but not --color auto).</p> 1689 1690<p>I'm gradually weaning the code off of itoa()/utoa() because sprintf 1691does this already. In this case "simple" probably means "let libc do it 1692for us".</p> 1693 1694<p>Rewrote for_each_pid_with_name_in() and renamed it to just names_to_pid(). 1695It shouldn't get confused trying to compare absolute and relative paths quite 1696so much anymore.</p> 1697 1698<p>lib/llist.c grew a new dlist_pop() function for removing a doubly 1699linked list entry while maintaining a circular list; tail and patch are 1700using it now.</p> 1701 1702<p>The musl guys suggested a new optimization flag 1703(-fno-asynchronous-unwind-tables) 1704that shaves about 10% off the binary size by removing a C++ism that crept 1705into gcc's idea of C. While I don't normally try to micromanage the compiler, 1706"-fstop-being-stupid" is a thing you have to hit gcc with from time to time.</p> 1707 1708<h3>Bugfixes</h3> 1709 1710<p>Felix Janda and I did a largeish rewrite of tail to 1711finally make it work right (we think). Still need to implement tail -f 1712someday (the tricky bit is making -f follow multiple files at once). 1713Felix also reported a bug in xpidfile.</p> 1714 1715<p>Juhani Haverinen pointed out that 1716python 3 doesn't work with config2help.py, so the detection logic looks 1717for python2 (until I get around to rewriting that in C). Elie De Brauwer 1718then fixed our first attempt at this, and also fixed uname's help string.</p> 1719 1720<p>Ashwini Sharma 1721pointed out the build was making a FLAG_ macro for " " which broke some 1722configurations. (That's a control character, not a command line option.)</p> 1723 1724<p>Jacek Bukarewicz pointed out a bug in chdir permission handling, and 1725a way to make env segfault. Both should be fixed now.</p> 1726 1727<p>The new function xexec_optargs() 1728replaces calls to xexec(toys.optargs) to avoid freeing and reusing optargs 1729during option parsing screwing stuff up (such as netcat's exec mode).</p> 1730 1731<p>The stat command's %a output was padded with leading zeroes, which 1732didn't match anybody else's behavior and thus made the test suite hiccup 1733between TEST_HOST and testing toybox. (If you go "TEST_HOST=1 scripts/test.sh 1734command" it sanity checks the tests against the host implementation.)</p> 1735 1736<p>Last release, "mkdir sub/sub && chmod 007 sub/sub && rm -rf sub" didn't 1737delete sub and didn't exit with an error either. Neither was correct, rm 1738should now be fixed.</p> 1739 1740<p> 1741<a name="26-07-2013" /><a href="#26-07-2013"><hr><h2><b>July 26, 2013</b></h2></a> 1742<p>Georgi Chorbadzhiyski maintains a <a href=https://github.com/gfto/toybox>git 1743mirror</a> of the repository on github, automatically updated from the 1744mercurial every 6 hours.

It adds 1755uuencode and uudecode from Erich Plondke, and enables Luis Morales' "who" by 1756default. Felix Janda and I cleaned up last year's "stat" submission and 1757enabled it. Ivo van Poorten added "groups". 1758Andre Renaud added "lsusb". I implemented "split", "pivot_root", and "mv". 1759</p> 1760 1761<p>The "help" command is implemented differently now (lib/help.c) and 1762each command can now understand --help (including both "toybox --help" 1763and "toybox --help command" in the multiplexer).</p> 1764 1765<p>The "pending" directory has several commands (find, xzcat, nbd-client, 1766logger, expr) which work but are not enabled by default pending further cleanup. 1767Ifconfig is enabled, but still in pending because it's only 2/3 cleaned up. 1768(It's an awkward halfway state but I'm not holding up the release for it.)</p> 1769 1770<p>I'm <a href=cleanup.html>documenting the cleanups</a> to teach 1771more people to do it, but the writeups aren't caught up yet. The 1772<a href=roadmap.html>roadmap</a> also got updated a bit with further analysis 1773of other projects, and the README and about pages got updated.</p> 1774 1775<p>Fixed _another_ "ls -C" segfault when terminal size can't be detected, 1776condensed the ls help text to fit on one page, implented --color, and taught 1777-l to print the major, minor numbers when showing block/char devices. 1778Argument parsing now handles "--" properly (to end option checking), 1779and the infrastructure can now handle bare --longopts that have no 1780corresponding short option (both were implemented before but didn't work). 1781Fixed an old bug in "patch", chmod grew -f, who grew -a. Isaac Dunham 1782fixed "-" vs "_" handling in modinfo, added a "firmware" output 1783field, added -b and -k support, and taught it that the ".ko" extension means 1784to look for the file at the specified path instead of under /lib. Felix Janda 1785moved file permission display code to lib so ls and 1786stat could share it. Ashwini Sharma spotted a bug in xabspath when the 1787last path component exists but we haven't got permissions to open it 1788(ala readlink -f /dev/sda as a normal user). 1789</p> 1790 1791<p>In the build infrastructure, scripts/findglobals.sh finds leaked global 1792variables. (Leaked means they aren't part of the global union: Other than glibc 1793debris, toybox should define "this", "toy_list", "toybuf", and "toys", and 1794that's it; the rest add memory footprint to every command for the benefit of 1795just one command; use GLOBALS() to stick 'em in the union.) Static linking 1796against libraries other than the host's libc now applies to feature probes 1797for unshare and such. Neuter stupid internationalization support that makes 1798various host "sort" commands put things in an order other than alphabetical 1799(breaking the multiplexer's binary search on command names). 1800 1801<p>You should now be able to build from a source control snapshot on a build 1802system that hasn't got python: if you disable CONFIG_TOYBOX_HELP. (The 1803release tarballs ship generated/help.h, but it's not in source control. 1804Eventually I should rewrite that python script in C.)</p> 1805</p> 1806 1807<p><b>LICENSE TWEAK</b>: After <a href=http://lists.landley.net/pipermail/toybox-landley.net/2013-March/000794.html>discussion</a> on the mailing list the "2 clause 1808BSD" <a href=license.html>license</a> got slightly simplified so the first 1809paragraph now says:</p> 1810 1811<blockquote><p>Permission to use, copy, modify, and/or distribute this 1812software for any purpose with or without fee is hereby granted.</p></blockquote> 1813 1814<p>It used to continue "provided that the above copyright notice and this 1815permission notice appear in all copies", but A) what's the point?

The segfault in ls 1899happened when it couldn't determine the screen size (last release changed the 1900default to -C and a screen size of 0 made column view unhappy), and cp got an 1901extensive rewrite bringing it up to date with the dirtree changes and fixing 1902a number of things it never did right in the first place. The xabspath() 1903code in the library now handles a symlink after ".." properly (and the test 1904suite checks for it).</p> 1905 1906<p>Infrastructure-wise the code is better about automatically setting the 1907error return code properly. Now error_msg() sets the exit code to 1 if it's 1908still defaulting to 0, and the global exit path does a fflush(NULL) with error 1909bit check rather than trying to be quite so granular about flushing. (That 1910means if we use printf() instead of xprintf() it still exits with the right 1911error code, it just doesn't end the program early on an output error.) 1912Minor bugfix so TOYBOX_DEBUG 1913doesn't always warn about the lack of suid bit when toybox is built with 1914at least one STAYROOT command. Bugfix for the option [grouping] logic 1915(and then further fixes to the error reporting pointed out by Ashwini Sharma). 1916dirtree_handle_callback() now has a prefix like the rest of the dirtree 1917functions. A lot of stuff doing manual path handling was switched to using 1918libc basename() (including, embarassingly, the basename command), which means 1919it now correctly detects "/trailing/slash/" which the previous code didn't.</p> 1920 1921<p>Also, last release included some accidentally checked in debug code that 1922disabled compiler optimization, so the binary size bloated a bit.

So here's 1935a new stable version.</p> 1936 1937<p>The new commands are cut (from Jason Kyungwan Han), touch 1938(from Choubey Ji), expand (from Jonathan Clairembault, and he fixed a 1939bug in login), and rm (from Rob Landley). Felix Janda added UTF-8 1940support infrastructure (for non-ascii character sets) with a config option. 1941Elie De Brauwer added tests for cat and sha1sum, and -so options to pidof. 1942The "ls" command defaults to -C (column view) now, and "readlink" now supports 1943-fenq.</p> 1944 1945<p>Portability work: toybox should now build against the musl C library, 1946and against older glibc versions (circa 2008, much before that and kernel 1947features we depend on start to drop out).</p> 1948 1949<p>The whole codebase got reindented from "one tab" to "two spaces" per 1950level. The option parsing logic now understands [groups] of commands (when more 1951than one in a group is selected it can switch the others off, or error out, 1952or other things). The error_exit() infrastructure can now longjmp back to an 1953earlier point instead of exiting. Each toys/* directory now has a README, 1954the first line of which is the fancy name menuconfig uses for the directory 1955(so no more hardwired directory list in scripts/genconfig.sh).</p> 1956 1957<p>Fixed a filehandle leak in getmountlist(). 1958Pass parent pointer to dirtree_add_node() so it can give error messages with 1959full path.

This affects menuconfig 1995and the actual source layout (toys/cp.c is now toys/posix/cp.c, and so on). 1996An android directory is planned (see the updated 1997<a href=roadmap.html#android>android roadmap analysis</a>).</p> 1998 1999<p>The FLAG_ macros for command option parsing and TT alias for the command's 2000global block are now automatically generated, commands should 2001#define FOR_commandname before #including <toys.h> to get the macros for that 2002command.</p> 2003 2004<p>An upgrade to the build infrastructure now allows commands with _ and - 2005in them, such as switch_root.</p> 2006 2007<p>Bugfixes: Avery Pennarun spotted a case where ls showed uid twice instead of 2008uid and gid, and that nice was using the wrong range of numbers. 2009The ls command also recursed inappropriately last time (not quite 2010properly converted for the dirtree changes last release), and now it's 2011fixed. Roy Tam pointed out a glitch in sh, and fixed df's percentage 2012calculation to match the POSIX spec. The kernel build didn't like our mktemp 2013and it does now. The wc command wasn't quite posix compliant (trailing spaces 2014break stuff). The ls command recursed inappropriately last time (not quite 2015properly converted for the dirtree changes last release), and now it's 2016fixed. The catv command wasn't displaying byte 255 correctly. Some lib 2017fixes (thinko in xpidfile). Fixed uname -m when running a 32 bit x86 binary 2018on an x86-64 host (it lies and says the system is i686, i586, or i486 depending 2019on what the toolchain that built the binary supported. This makes builds in 2020a 32 bit chroot on a 64 bit kernel break less.)
