I delayed it a bit trying to get some 22 of the many half-finished projects (dd, ping, lsof, iconv, cut, sysconf, 23 the cp --parents option...) finished/promoted/tested, but decided adding big 24 things at the end of the dev cycle would be too destabilizing.</p> 25 26 <p>A couple <b>new features</b> slipped in anyway. Ilya Kuzmich added head -c 27 and strings -t (and corrected strings' output in a couple places). Elliott 28 Hughes taught file to recognize Macintosh (Mach-O) binaries.</p> 29 30 <p><b>NOTE</b>: the chrt command is broken when built against musl-libc 31 because that project's maintainer decided he didn't like the system calls 32 it depends on, so he 33 <a href=https://git.musl-libc.org/cgit/musl/commit/?id=1e21e78bf7a5>removed 34 them from his libc</a>. The prebuilt binaries are built against musl, 35 so the chrt command there will always say -ENOSYS. (It works fine built against 36 glibc, and presumably bionic or uClibc.)</p> 37 38 <p><b>Bugfixes</b>: Remounting (mount -o remount,rw) should work properly now, 39 and we fixed another place ps was segfaulting when /proc 40 entries vanished out from under us (a hard to hit race condition 41 mostly noticeable in long-running "top" exiting; error value was treated 42 as a pointer). Elliott Hughes fixed a -Wformat warning in expr.c, 43 and made xargs split the command 44 line at ARG_MAX (which is 1/4 the stack size ulimit, which normal users 45 can arbitrarily increase but execve() will complain if they don't). 46 Josh Gao made netcat -l exit after handling a request, and reported a 47 seq bug (seq "1000000 10000001" output 1e+06, fixed now). Zach Riggle fixed a 48 broken URL in the README. Rob fixed env -0 checking the flag wrong so 49 it didn't work in combination with other flags (typo).</p> 50 51 <p><b>Plumbing</b>: 52 Replaced mbrtowc() with a new utf8towc() that doesn't have a context 53 struct or care about locale. A bugfix in comma_scan() (wasn't removing an entry at the end 54 of the list) is why remount _sometimes_ worked (depending on argument 55 order), xgetaddrinfo() is now separate from xconnect(), 56 atolx_range() learned the w (word=2) suffix, and b is now (block=512) instead 57 of (byte=1).</p> 58 59 <p><b>Build</b>: Patrick Oppenlander added a workaround for a bug in config2help.c 60 that resulted in segfaults on newer toolchains. (It was actually a use 61 after free error; the build infrastructure isn't nearly as heavily audited as 62 code that gets installed on the target; oops.) A new GITHASH 63 environment variable can force the build version from 64 the command line, and the build checks for .git in the top directory 65 before asking git what our version is (so it isn't confused by ../../.git 66 in an enclosing directory). Added a build #warning about musl intentionally 67 breaking chrt (as with nommu fork() musl now provides a broken 68 stub function so compile-time probes for its existence think it's there, and 69 you can't run the result to test behavior when cross compiling).</p> 70 71 <a name="19-06-2017" /><a href="#19-06-2017"><hr><h2><b>June 19, 2017</b></h2></a> 72 <blockquote><p>It is a well-known fact that those people who most want to rule people are, ipso facto, those least suited to do it. 73 To summarize the summary: anyone who is capable of getting themselves made President should on no account be allowed to do the job.</p> 74 <p>- The Hitchhiker's Guide to the Galaxy</p> 75 </blockquote> 76 77 <p><a href=downloads/toybox-0.7.4.tar.gz>Toybox 0.7.4</a> 78 (<a href=https://github.com/landley/toybox/releases/tag/0.7.4>git commit</a>) 79 is out. No new commands this time, but 80 <b>chrt</b> and <b>dmesg</b> got promoted out of pending.</p> 81 82 <p><u>New features</u>: 83 Rob rewrote paste, which should work much better now, and added grep 84 -M and -S to match and skip wildcards respectively (useful with -r). 85 Elliott's updated dmesg has -T and --color. The file 86 command can recognize gzip now, uptime grew -s, date grew %N, env knows - as a first argument 87 means -i (posix!) and grew -0, ls defaults to -b 88 instead of -q now when there's a tty, and ls has a new -ll option (with 89 --full-time as a compatibility synonym) showing nanoseconds and (for some 90 reason) timezone. (Why do individual files have timezones?) Elliott added 91 "uudecode -o -" support. Illya Kuzmich taught head -v and -q. The cpio 92 code no longer adds the "TRAILER!!!" entry by default (initramfs extractor 93 doesn't care) without which you can concatenate cpio archives with "cat". 94 (Use the new --trailer option if you want the legacy behavior.) 95 In pending, fdisk compiles now and tar understands bzip2.</p> 96 97 <p><u>Build</u>: 98 The "make install_airlock" target now symlinks bc from the host because 99 the kernel <a href=https://landley.net/notes-2013.html#28-03-2013>inexplicably</a> 100 needs that to build. This was motivated by 101 <a href=https://github.com/landley/mkroot>mkroot</a>, which builds under 102 a toybox airlock directory.</p> 103 104 <p>Lots of work on the test suite, mostly from the Android guys who are now 105 running it under Android. This fixed several existing tests that didn't 106 pass, made more tests run on a toybox-only system, and so on. The test suite 107 infrastructure now has a second testing function, 108 "testcmd", which supplies the command name being tested (bypassing 109 shell builtins).</p> 110 111 <p>Various android build and config fixes, getting closer to being able 112 to let android someday use scripts/make.sh instead of generated/* snapshots. 113 Also more work into building under android's NDK; not quite there yet 114 but much closer. 115 Use nproc in scripts/make.sh detect available processors (so you can control the SMP level with taskset). 116 Removed the old uClibc compatibility glue, it's been 5 years since their 117 <a href=http://lists.busybox.net/pipermail/buildroot/2016-December/180102.html>last release</a>.</p> 118 119 <p>The new config option TOYBOX_PEDANTIC_ARGS checks arguments when there 120 are no arguments, so things like "uptime" no longer silently ignore arguments 121 you pass but instead refuse to run.</p> 122 123 <p><u>Docs</u>: 124 The FAQ now has more than one entry. Commands no longer output the full 125 help text for argument errors but instead just say "See %s --help" with the 126 command name (in addition to the actual error message). 127 Elliott did a big period-ectomy on all the --help text, and 128 we cleaned up some tab/space inconsistency. The 129 non-html help -a output now has separators with the command name. 130 The top/iotop and pkill/pgrep help text now describe a lot more of what 131 the commands can do. Twitter's code of conduct page went down so we 132 mirrored the text locally.</p> 133 134 <p><u>Bugfixes</u>: 135 Fixed a race condition in ps/top where a process that exited right as we 136 read its data returned a different error value than we were expecting (which 137 was causing long-running top instances to occasionally exit), 138 mount now gives an error if it can't autodetect the filesystem 139 type, ps no longer queries the terminal size when output isn't to a tty 140 (so "ps -A | cat" doesn't vary), date's chkmktime() was replaced with 141 simple range checks for fields (to avoid false positives from things like 142 timezones and daylight savings time), removed %s from date's help (we 143 didn't implement it, we have @seconds[.nanoseconds] instead), fixed 144 zcat's buffer flush logic (which was always failing on files larger 145 than 32k), and factor now detects requests for numbers >64 bits and fails 146 loudly instead of producing incorrect answers. 147 Elliott fixed touch -a/-m (they were backwards), and allowed ':' in 148 setprop's property names. Grep now exits with 2 for errors (so -q can 149 distinguish "didn't find" from "didn't work"), doesn't stop on symlinks 150 that point nowhere (there was an error_exit() that should just be a warning), 151 and provides error messages for files we could open but not read.</p> 152 153 <p><u>Library</u>: 154 New library functions: strend() complements strstart(), minof()/maxof() 155 are min/max macros that evalute arguments once and autodetect type (why 156 isn't this in libc?), xmmap() checks MAP_FAILED (which is not NULL).</p> 157 158 <a name="21-02-2017" /><a href="#21-02-2017"><hr><h2><b>February 21, 2017</b></h2></a> 159 <blockquote><p>Only six people in the Galaxy knew that the job of the 160 Galactic President was not to wield power but to attract attention 161 away from it.

The <u>new commands</u> this time are <b>ftpget</b>, <b>ftpput</b>, <b>microcom</b>, and <b>ascii</b>.<p> 167 168 <p>We also had two command _demotions_ out of defconfig: 169 <b>hostid</b> got moved to toys/example and 170 switched to "default n" because despite <a href=http://pubs.opengroup.org/onlinepubs/9699919799/functions/gethostid.html>still being in posix</a> 171 the concept of a unique 32 bit number identifying a system is something 172 Linux outgrew about the time Pauline Middelink wrote the first IP 173 Masquerading code. And Elliott did a complete rewrite of <b>dmesg</b> introducing 174 two codepaths that I didn't get a chance to unify and didn't want to 175 hold up the release for, so that's back in pending.</p> 176 177 <p><u>New features</u>: Rob added units to <b>find</b> -atime and friends 178 (with the legacy -amin alias). Elliott added color and -w to dmesg, fallocate 179 -o, and improved file's ELF parsing. Steve Muckle added -d and finit_module 180 support to modprobe. Rob and Elliott tweaked the 181 ps/top display format a bit more (extending the USER field from 8 to 18 chars 182 and putting + at the end of string fields that got truncated). 183 df -a isn't entirely new, but wasn't documented and needed a bugfix.</p> 184 185 <p><u>Bugfixes</u>: 186 Last release broke oneit because -c didn't get moved to xopen_stdio() (oops). 187 Rob and Elliott simultaneously spotted ps padding each line to 99999 188 chars when there's no tty (serial console or adb); now it pads to 80 in 189 that case but also switches on -w to avoid field truncation. The "tty" 190 field also sometimes had trailing debris (that's fixed now). And "top" was 191 endlessly redrawing with out tty because receipt of the ANSI size probe 192 results would set SIGWINCH, and handling that sent another ansi probe. (Sigh.) 193 And while we're there, replace "ADDR" with "BIT" in ps -l so there are 194 more than 4 chars left for the "CMD" field on 64 bit systems.</p> 195 196 <p>Izabera pointed out that split -b and -l can't mix, and suggested seq should 197 multiply to avoid accumulating rounding errors from repeated fractional 198 increments. Wang Xiao Jian fixed a bug in sort -k. 199 Elliott let getprop use the @ character in property names, and 200 Dimitry Ivanov removed the name length limit for system properties. 201 Elliott also improved some error reporting and improved top -H's display 202 of thread names. 203 204 <p>Josh Gao pointed out that recursive operations on . and .. could be ignored 205 in chmod -R (and the resulting generic fix to dirtree_notdotdot() fixed 206 it in several other places).</p> 207 208 <p>Justin Cormack caught tar producing a warning to stdout that screwed up 209 "tar c" to stdout. 210 Rob fixed an option parsing bug (where switching off a --longopt in menuconfig 211 confused the parser), and another one where an option excluding itself 212 (ala "abc[-ab][!abc]" with "command -a -b") would segfault.</p> 213 214 <p>There's some sort of gcc stack over-optimization bug where musl-libc's 215 version of vfork() doesn't get marked with attribute(returns_twice) so 216 stack varabiles in the same function after that get semi-randomly overwritten 217 when the optimizer decides to reclaim the space. So add the attribute 218 to the function the XVFORK() wrapper macro calls. (It's a nommu thing.)</p> 219 220 <p>Fixed a couple variable size mismatch bugs that were only tested on 64 bit 221 (printf %x 64) or only tested on 32 bit (modprobe), removed some 222 unnecessary casts in stat.</p> 223 224 <p>Continuing attempts to build under Android NDK brought up that posix 225 defines the global 'stdout' as a macro, which older versions of bionic 226 turned into an array member, but a function was using it as an argument 227 name. (This worked in the AOSP build because it only builds against current 228 bionic, where there's a global 'stdout'.)</p> 229 230 <p>Several commits argued with clang's warning generation, eventually 231 settling on a variant of __attribute__((__shut_up__)).</p> 232 233 <p>Android should no longer give spurious error messages 234 when you "ps -A | head" about EPIPE on output. (Older versions of bionic 235 set an error handler on SIGPIPE, but it shouldn't do that now. More recent 236 versions of adb set the SIGPIPE handler to SIGIGN instead of SIGDFL, 237 leading to write returning an error message instead of silently killing 238 the program. So we set it back to the default.)</p> 239 240 <p><u>Docs</u>: 241 Removed website link to the gmane archive (which didn't survive gmane's 242 change of ownership). The FAQ now answers a _second_ question. (Woo!) 243 Some roadmap updates.</p> 244 245 <p><u>Build tweaks</u>: 246 Upgraded "make install_airlock" target to only warn about missing 247 commands (unless $PEDANTIC is set) when it sets up the hermetic build 248 path. (The plan is still to implement everything but the toolchain 249 binaries in toybox, but in the meantime we're symlinking other stuff from 250 the $HOST that isn't ready yet. See 251 <a href=https://github.com/landley/mkroot>mkroot</a> for an example using 252 this.)</p> 253 254 <p>Elliott and Rob continue to poke at building toybox with Android's NDK, 255 but it's a work in progress (<a href=http://lists.landley.net/pipermail/toybox-landley.net/2016-December/008767.html>thread</a>). Various changes 256 removing libcutils dependencies and adding an selinux dependency to getprop 257 are fallout from this.</p> 258 259 <p>Cross-compiling from Macs needs to use "gsed" instead of apple's 260 version, so teach the build to use that name if it exists in the $PATH. 261 If you try to build without running config first, you should get better 262 error reporting now. Added a workaround for Centos' broken "which" command 263 producing output when it _can't_ find a name in the $PATH.</p> 264 265 <p><u>Library</u>: 266 The new dirtree flag DIRTREE_PROC skips non-numeric entries so things 267 like ps and top can scan /proc more efficiently.</p> 268 269 <a name="21-10-2016" /><a href="#21-10-2016"><hr><h2><b>October 21, 2016</b></h2></a> 270 <blockquote><p>Probability factor of one to one.

A new toys/net directory was added, moving ifconfig, netcat, 291 netstat, rfkill, and tunctl there so far.</p> 292 293 <p><b>Upgrades</b>: All commands now parse --version when they understand 294 --help, but "true" and "false" should now ignore their arguments entirely. 295 We taught stat to handle "%12x" and "%.12x" printf-style escapes, which 296 apparently other versions do. The ifconfig output now shows the interface's 297 device driver. Added patch -d and --dry-run, wc can now do -cm together, 298 find has a NOP -noleaf so scripts that use that don't break, add -c to md5sum 299 and sha1sum. Elliott taught ps to treat extra aguments as additional -p 300 pids, implemented xxd -s, did a number of upgrades to file (added -HL, 301 support for ar files, improved ELF support to report android API level 302 and stripped/not stripped and it no longer prints a guessed build ID type). 303 Elliott also added optional build-time support for using openssl's 304 assembly-optimized md5sum/sha1sum implementations (leading to a new 305 <a href=design.html>design</a> policy on shared libraries).</p> 306 307 <p><b>Bugfixes</b>: Too many fixes to "ps" and "touch" to list, from both 308 Elliott and Rob. Rob taught sed to handle s/[[:space:]/]// type sequences 309 properly, switched grep to a better 310 workaround 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, 311 made du max out at 2 terabytes instead of 2 gigabytes on 32-bit systems 312 (it was always designed to, but was missing a typecast), 313 fixed the option parsing infrastructure (config options that remove command 314 line options got the placeholders wrong), fix to printf for printing 315 octal digits and handling the (posix-mandated) difference between %b and 316 non-%b octal output, reading from "-" no longer closes stdin when done, 317 netcat -L works with nommu (although it may need more portability work), 318 and you can now "make test_scankey" if you want to. Several commands 319 (stat, makedeves, chgrp, cp, find) handled user name lookup failure badly 320 (stat was segfaulting if you interrogated a file belonging to a nonexistent 321 user, "chown 12345 file" errored out if you didn't have that user 322 in /etc/passwd... now they should all print/accept the number when 323 appropriate). "LC_ALL=C ls -Cs --color" produces the same output 324 as other versions (two spaces padding, -k hardwired on).<p> 325 326 <p>Kyungsik Lee fixed a bug 327 in cp (readlink() doesn't actually null terminate the string it reads in), 328 Elliott Hughes made pgrep/pkill return success/failure, fixed trailing 329 whitespace in netstat, fixed a SMACK symbol conflict due to linux/xattr.h 330 changing, fixed ls -sh, and added a lot of 331 stuff to the <a href=roadmap.html>roadmap page</a>. 332 Izabera pointed out cmp -l and -s can't be selected at the same time, 333 that timeout was never actually checking -v, that ls should default to -q 334 when output is to a tty, and that "file -" would sometimes try to open "-" 335 instead of stdin. 336 Usischev Yury pointed out a use after free error, and that id shouldn't 337 call exit() directly. Matthias Urhahn pointed out that stat(2) returns 338 hardwired 512-byte units, so stat.c was wrong. David Hedges pointed out 339 that route could only handle 10 character interface names when the kernel 340 can do 15 (it's still in pending for a reason, but fixed). Evgenii 341 Stepanov found and helped diagnose one of the more subtle ps bugs fixed 342 this time around.</p> 343 344 <p>Calling "make test_blah" no longer causes make to error out if the last 345 test fails (and thus returns a nonzero error code). 346 Building single commands and the multiplexer used to require a "make clean" 347 between them (because they had different config files both of which were older 348 than generated/config.h so it didn't get rebuilt; now it just always 349 rebuilds it).</p> 350 351 <p>The defconfig build is now slightly less broken on older centos versions 352 (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> 353 354 <p>Several commands were over-using xprintf(), which flushes its output 355 to check for error (something you only need to do maybe once per line, 356 and even then maybe only in loops because xexit() flushes and checks 357 ferror() for you and adjusts the exit code if we wrote stuff to stdout 358 that couldn't be printed). Lots of little flushes are inefficient, 359 so most things can use normal printf(). (Retransmission 360 of short writes is presumably libc's problem since it's buffering the 361 output and all.)</p> 362 363 <p><b>Library:</b> 364 New library functions readlink0() and readlinkat0() which properly null 365 terminates the symlink value (which the stock libc function inexplicably 366 doesn't). 367 The new do_lines() function interates reading lines from a filehandle 368 and calling a function on each line. 369 New function pollinate() factoring out netcat's poll() loop so things 370 like telnet can use it. 371 New functions getusername() and getgroupname() return a 372 char * given a uid/gid (and return a string representation of the number 373 if the lookup fails), and xgetpwnamid/xgetgrnamid were renamed to 374 xgetuid/xgetgid and now return an integer instead of a struct (also helping 375 handle lookup failures, you can still return the uid/get for "12345").</p> 376 377 <p>Switched atolx() to use long long internally. 378 Renamed xopen() to xopen_stdio() and made a new xopen() that never returns 379 stdin, stdout, or stderr (duping /dev/null into the filehandles as necessary). 380 New function xopenro() opens a file read only with one less argument, and 381 understands that "-" means stdin. New flag WARN_ONLY tells these functions 382 to just print a warning on failure, and return -1 instead of exiting. 383 Misc new functions like openro() which defaults to the WARN_ONLY behavior 384 and notstdio() which dup()s a filehandle up beyond stdin/out/err backfilling 385 with /dev/null as necessary. The WARN_ONLY flag let us remove the failok 386 argument from loopfiles().</p> 387 388 <p>New TOYFLAG_NOHELP disables --help processing (which "true" and "false" 389 should not do).</b> 390 391 <p>The test suite now has NOSPACE=1 to ignore whitespace (using diff -b to 392 check results), which helps TEST_HOST pass the same tests as toybox. 393 Fixes to chattr and date tests. It also has a new variable $C with the 394 absolute path to the command being tested (bypassing shell builtins), 395 and a function testcmd() which is just like testing() except it prepends 396 the command name ($C) to the test command line as well as the test 397 description.</p> 398 399 <a name="02-06-2016" /><a href="#02-06-2016"><hr><h2><b>June 2, 2016</b></h2></a> 400 <blockquote><p>When the 'Drink' button is pressed it makes an instant but 401 highly detailed examination of the subject's taste buds, a spectroscopic 402 analysis of the subject's metabolism, and then sends tiny experimental 403 signals down the neural pathways to the taste centres of the subject's 404 brain to see what is likely to be well received.

(Pending also had minor 422 cleanups to more and lsof, but no promotions this time around.)</p> 423 424 <h2>New Options</h2> 425 <p>Izabera implemented env -u, suggested adding seq -w, made factor 426 use full unsigned 64 bit math even on 32 bit platforms, pointed out base64 427 -w0 should disable wrapping, and sped up wc -c. 428 Elliott Hughes added mount -o relatime, xxd -p -r, and od -w. 429 Sameer Pradhan (or possibly Bilal Qureshi) suggested adding stat -tL -c %m%t%T. 430 Tom Cherry added getprop -Z. Paul Barker added hostname -b and -F. 431 Rob added ls -b, made ls -q work with utf8, 432 made sed -f - read from stdin, and added top -O (like ps -O).</p> 433 434 <p>Elliott and Rob <b>added Thread support to ps and top</b>, 435 with -o TID, TNAME. We also added -o PCY (android scheduling policy), 436 -o BIT (process is 32 or 64 bit), and -o TNAME now shows the parent 437 command name for threads.</p> 438 439 <h2>Documentation</h2> 440 441 <p>Rob added the sed invocations to convert tabs/spaces and back to 442 design.html. Isaac Dunham updated hexedit's help text. 443 Jakob Flierl pointed out a broken URL in the README.</p> 444 445 <p>Rob also redid the naming scheme of sed's pattern manipulation code to 446 remove the gratuitous references to Roger Zelazny's "Amber" series, since it 447 was confusing people.</p> 448 449 <h2>Bugfixes</h2> 450 451 <p>Grep -H and -n should now work properly with -ABC. Andy Chu pointed out an 452 out of bounds access for zero length lines in rev, fixed a buffer overflow 453 in diff -r, and fixed operator precedence in expr (although Rob is rewriting 454 chunks of expr so toysh can use its plumbing for $(( )) ). 455 Patrick Ohly fixed the too-aggressive suid permission dropping logic. 456 Josh Gao fixed a segfault when find -iname got no argument, and 457 made tail -f work right with just one file argument. 458 Tom Marshall cleaned up tar's long filename support and improved 459 the tar tests, and reported another find bug (with -iname -o -iname not 460 tracking copy lifetimes properly) that got fixed.</p> 461 462 <p>Elliott Hughes fixed wc -c to not trust zero length files to actually be 463 zero length (/proc does that), fixed "mount -o rw,remount /system" on 464 Android, removed trailing spaces on ps -o cmdline, fixed pkill -9 and 465 the corresponding tests, made "insmod -" work, fixed top -b and tail -NUM, 466 pointed out that ps shouldn't trim numeric fields for display size limits, 467 and added some more 468 explicit "sort" calls to make pipelines so build tempfiles are easier to cache. 469 Rob <a href=https://github.com/landley/toybox/commit/32b3587af261>fixed an insane sed thing</a> the perl 5.22 build was doing. 470 Fixed mount -o to properly pass in leftover string data, and 471 <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 472 to fix some bitrot in the kernel NFS driver's string parsing attached 473 to that message).</p> 474 475 <p>George Burgess IV corrected some variable types in traceroute. 476 Base64 now wraps == properly. Fixed two bzcat segfaults reported by 477 John Regehr. Andy Chu found a segfault in "sed -e 'c\'" with no trailing 478 line, and implemented mv -n and cp -n. The cyanogenmod guys pointed out that 479 cp -a shouldn't complain if a non-root user can't chown, and we added 480 the output path to cp -r error messages while we were there (before was just 481 the filename).</p> 482 483 <p>Samuel Holland fixed blkid's handling of vfat labels, and 484 fixed a segfault when basename was passed an empty string and an empty 485 suffix. Davis Mosenkovs fixed touch -t seconds parsing. 486 Rob fixed a bunzip bug reported by John Regehr (the bad CRC 487 error message was printing a NUL argument).</p> 488 489 <p>Not all of the commands build standalone, but more of them do now; 490 scripts/single.sh can now build a "mv" that isn't actually "cp". 491 The dependencies are more granualr, so "make top; make ps" no longer 492 produces a broken ps that ignores -A (because ps.o wasn't getting rebuilt 493 even though top had the FLAG macros for -A zeroed).</p> 494 495 <h2>Build</h2> 496 <p>Rob added a <b>warning when building commands out of 497 pending</b>. (The pending directory is full of code that hasn't been 498 properly vetted. Use at your own risk.)</p> 499 500 <p><b>New build targets let you build individual commands by name</b>, ala 501 "make ls cat ps", and you can run the test suite for each standalone 502 command with "make test_ls" and such. 503 "make list" shows all such standalone commands in defconfig, and 504 "make list_pending" shows unfinished commands from toys/pending 505 ("make list list_pending" shows both together). "make clean" now deletes 506 these filenames at the top level, and the corresponding unstripped files 507 live in the directory generated/unstripped.</p> 508 509 <p>Nicholas Boichat suggested switching make.sh to use $! for process 510 enumeration during parallel builds (which is both more efficient and more 511 portable), and suggested shell builtin replacements for wc/awk/sed so the 512 build loop has fewer forks now.</p> 513 514 <p>Lots of work on the test suite, much of it due to Andy Chu. It now 515 consistently prints the name of the command being tested at the start of each 516 test (and the common infrastructure does that, not each individual test), and 517 "make tests" actually runs all the available tests now. 518 Seperated pgrep and pkill tests, split lsattr/chattr, added fstype and base64 519 tests. The "tests/files" directory now collects files for tests to 520 use, with blkid, bzcat, and utf8 subdirectories: the $FILES variable 521 gives a path to it, so "$FILES/blkid/ext2.bz2" and so on. 522 The testsuite now has test files with 3 different types of "not utf8 output" 523 sequences that require escaping, plus some combining character torture 524 tests, direction reversals, and so on.</p> 525 526 <p>Added dependencies on TOYBOX_FORK to various pending commands that need 527 nommu conversion (which should fix the allyesconfig build).</p> 528 529 <p>Static builds with selinux should work again.</p> 530 531 <h2>Library</h2> 532 533 <p>New bufgetgrgid() and bufgetpwuid() functions cache previous lookup info 534 rather than repeatedly traversing /etc/passwd and /etc/group (which is slow). 535 Added xpipe() to lib to catch pipe creation failure. 536 The HELP_ macros generated by config2help.c now use a capital prefix 537 to avoid collicing with help_exit() and such.</p> 538 539 <p>The dirtree infrastructure got a cleanup pass in preparation for adding 540 infinite recursion depth support (needed by rm -r), updated the 541 <a href=code.html#ib_dirtree>documentation</a> to describe the new 542 semantics (removing dirtree_start() and adding dirtree_flagread()). 543 Now dirtree_recurse() takes the new dirfd as an argument.</p> 544 545 <p>Split out _xexit() from xexit() and let sigatexit() set multiple 546 callbacks.</p> 547 548 <p>For years the man pages have said to #include <sys/types.h> to get 549 major/minor/makedev but now that glibc 550 <a href=https://sourceware.org/ml/libc-alpha/2015-11/msg00253.html>has vowed 551 to break existing programs</a> and replace it with another nonstandard header 552 not in posix or lsb, we added our own functions to lib/ to do the transform 553 ourselves (based on what the kernel actually expects).</p> 554 555 <h2>Portability</h2> 556 557 <p>Debian unstable started needing an extra header #include for some reason, and 558 although printf("%.*s", INT_MAX, s) worked fine on Ubuntu 12.04 it 559 didn't on 14.04, so added a workaround for that. Typecast a printf because 560 wchar_t isn't a rigidly defined size. RLIMIT_RTTIME was 561 added to the kernel in 2008 but you can't expect uClibc to have noticed yet, 562 nor did it #define MS_RELATIME (added in 2006), or prlimit (2010)... 563 (Given the improvements in musl and bionic, uClibc support may be dropped 564 in a future release.) Given that the xattr functions were added during 565 linux 2.5, we can #include its header unconditionally.</p> 566 567 <p>Renamed basename_r() to something else to avoid conflicting with freebsd's 568 libc, and both scripts/install.h and scripts/config2help.c no longer include 569 toys.h (to make cross-compiling from systems we don't run on easier).</p> 570 571 <p>Debian bug 635570 did something unspeakably nonportable, depending on 572 "sed -e 'a\'" (with no next line of the pattern, so an unterminated 573 continuation) to add a newline to the last line of input if and only if 574 that last line of the input didn't have a newline, and to take no other 575 action. This is well into "depending on a bug" territory, but we implemented 576 it because otherwise Debian's install broke. (Of course this behavior 577 is undocumented, non-obvious, and doesn't really make logical sense.)</p> 578 579 <p>CONFIG_TOYBOX_NORECURSE now disables the stack measuring logic (which 580 was giving some "security" code fits). Also we typecast pointers to (long) 581 before comparing them to avoid spurious compiler "optimizations" that 582 break the code.</p> 583 584 <a name="02-02-2016" /><a href="#02-02-2016"><hr><h2><b>February 2, 2016</b></h2></a> 585 <blockquote><p>"I checked it very thoroughly," said the computer, "and that 586 quite definitely is the answer.

Added grep -ABC, 597 swapon -d (discard), mkswap -L (label) and UUID support, and find -delete. 598 Izabera added free -h and unshare -f. Josh Gao implemented tail -f. 599 Jose Bollo submitted cp --preserve=context,attr. Kylie McClain added 600 mktemp -u.</p> 601 602 <p>In pending there's the start of a vi command, and Sameer Pradhan contributed 603 a new dhcp6. This cycle saw several rounds of route cleanup and a little dhcp 604 cleanup, but neither are complete yet. Lipi Lee did some cleanup to netstat.c 605 and Elliott Hughes removed warnings from traceroute.</p> 606 607 <p>Lots of updates to ps: several new -o options, -k (--sort) -O and -M, 608 improved compatibility with Android's historical behavior, and 609 extensive internal code cleanup (including the removal of all 610 the magic constants).</p> 611 612 <h3><b>Website</b></h3> 613 614 <p>Dreamhost restored the <a href="#12-21-2015">missing 11 months</a> 615 to the mailing list archive, in the process deleting the month after 616 that. Now they've asked if I have mbox files archiving the new 617 gap (between December 20, 2015 to January 21, 2016, and presumably they 618 could also fill in the gap from December 14, 2014 to January 3, 2015 that's 619 been there since the last time they did this), 620 but due to some gmail filtering I've 621 <a href=http://landley.net/notes-2012.html#15-10-2012>never 622 been able to disable</a>, my copy of those files is spread among 3 different 623 mbox files I'd have to sort/filter/collate.

Fixed sort -f and added test cases. 632 Assume 80 columns in "ls -m | cat", ls -L is no longer backwards, 633 and ls of files with no paths no longer uses an uninitialized (zero) dirfd. 634 Several bugfixes 635 to find (Gilad Arnold fixed -perm, Daniel K. Levy fixed "find . -exec echo {}", 636 and while we're there I fixed find --prune, made "find . -execdir 637 echo {} + -execdir ls {} +" work, and ripped out the environment size 638 measuring code that checked for a 128k limit removed back in linux 2.6.22). 639 Elliott Hughes fixed the date command's parsing of 4 digit 640 years and documented the %s escape, fixed hwclock -u, and pointed out 641 that runcon needs to exec to do its job (not recursively call another 642 command_main() in the same process). Tom Marshall reported that blkid was 643 handling ext2 wrong. Mike Moreton corrected cpio extraction's uid and gid 644 values, and added a --no-preserve-owner option. Fixed the SUID permission 645 dropping logic (which was a bit over-zealous, preventing some commands from 646 running at all).</p> 647 648 <p>I'm told that debian-testing broke its libc so the nsenter build breaks, 649 but my attempts to install the debian-testing network cd image under 650 qemu keep breaking. Maybe someday they'll fix it enough I can actually 651 reproduce the problem. (Debootstrap under unbuntu builds an ubuntu-flavored 652 chroot in which toybox builds fine.)</p> 653 654 <h3><b>Documentation</b></h3> 655 <p>Rewrite of the about.html page, tweaks to design.html, and a re-triage of 656 sbase in roadmap.html.

Better error message for ls -r on unreadable 835 directories, and ls -Z now uses O_PATH (with the /proc/self/fd/%d 836 workaround for kernel stupidity as necessary).</p> 837 838 <p>Date now understands @unixtime[.fraction] and uses -D for 839 the set-side format (matching busybox's extension for this). The seq -f 840 string now checks that it's got exactly one %f escape with the correct 841 attributes (and a whole bunch of test cases for it). Fixed a bug 842 in od that screwed up the position indicator on arm and mips. 843 In stat the d/h units moved from %d %D to the default string. 844 And patch can now correctly apply hunks with trailing context to the start of 845 the file.</p> 846 847 <p>The prompt argument moved out of yesno() (the caller can print the prompt 848 themselves). Replaced toys.exithelp with help_exit(). Added new 849 XVFORK() macro, and xpopen_both() calls /proc/self/exe when passed 850 a NULL argv (see cpio -p for example usage). Replaced toys.recurse 851 with toys.stacktop so the recurse or re-exec decision is now based 852 on bytes of stack space used. Marked a bunch of command-local functions 853 static.</p> 854 855 <p>New additions to lib/ include strlower(), xconnect(), and the 856 aforementioned help_exit(). 857 The testsuite now has some infrastructure tests based on "example" 858 commands such as toys/examples/test_human_readable.c. 859 The login command finally got a long-overdue cleanup (it's one of the 860 commands that predate the "pending" directory but were part of the reason 861 for it). Hexedit had an 862 uninitialized variable (of course gcc didn't spot it, it was too busy 863 warning about "may be used uninitialized but never actually is" variables).</p> 864 865 <p>Tweaked makefile so 866 "make CROSS_COMPILE=prefix-" (as well as "CROSS_COMPILE=prefix- make", 867 which still works). Toybox is now installed chmod -w so broken installers 868 (like the bunzip2 package's) that try to overwrite existing binaries won't 869 knock out the whole of toybox. 870 GCC 5.2.0 stopped being able to compile Linux 2.6.12's kconfig, but 871 we added a workaround. You can now build uptime without utmpx.h. 872 Alejandro Joya pointed out that enabling smack required smack on the host 873 as well as target when cross compiling, which is now fixed.</p> 874 875 <p>Note: toybox can autodetect nommu support when building with a uClibc 876 toolchain 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>, 877 but <a href=http://github.com/richfelker/musl-cross-make>with musl-libc</a> 878 you'll have to enable CONFIG_TOYBOX_MUSL_NOMMU_IS_BROKEN to work around the 879 fact they provide a non-functional fork() implementation that always returns 880 -ENOSYS, to prevent you from compile-time probing for nommu support when 881 cross-compiling. Unfortunately "preventing you from probing" seems to be 882 an explicit policy with musl, they also don't provide an "#ifdef __MUSL__" 883 because their library is perfect and you're only ever allowed to work around 884 other people's bugs, not theirs. So we have to use menuconfig to manually 885 enable musl-specific bug workarounds.</p> 886 887 <a name="23-07-2015" /><a href="#23-07-2015"><hr><h2><b>July 23, 2015</b></h2></a> 888 <p>I recreated the <a href=downloads/toybox-0.6.0.tar.gz>0.6.0 source tarball</a> 889 (new sha1sum 08fb1c23f520c25a15f262a8a95ea5b676a98d54) 890 because I forgot to add --prefix to the git archive command when I updated 891 my release script from mercurial, so the files weren't in an enclosing 892 directory.

Toybox 928 came out of mothballs in November 2011 <b>because</b> it could be 929 relicensed. That's what opened up a new niche busybox wasn't already 930 filling with a 10 year headstart.</p> 931 932 <a name="asterisk_back" /> 933 <p>The article has plenty of smaller issues<a href=#asterisk>*</a>, but 934 given that I gave an entire talk at Ohio LinuxFest in 2013 935 (<a href=http://landley.net/talks/ohio-2013.txt>outline</a>, 936 <a href=https://archive.org/download/OhioLinuxfest2013/24-Rob_Landley-The_Rise_and_Fall_of_Copyleft.mp3>audio</a>) on why I switched away from GPL for 937 my projects, that one bugs me.</p> 938 939 <h3><b>New stuff this release</b></h3> 940 941 <p>There's a new android menu in menuconfig, and rather a lot of Linux 942 Security Module support (Smack for Tizen from Xavier Roche and Jos Bollo, 943 and SELinux for Android from Elliott Hughes; see 944 the Security Blanket menu under global settings in menuconfig) has 945 trickled in, although there's still more to come.</p> 946 947 <p><b>New commands:</b> Added reset, nproc, ionice, and iorenice. 948 Elliott Hughes contributed xxd, runcon, 949 restorecon, load_policy, getenforce, setenforce, getprop, and setprop. 950 Promoted shred, nsenter, and hwclock.</p> 951 952 <p>You can once again build catv now the flag infrastructure's been updated to 953 let it coexist with cat -v. 954 And on a long plane flight I wrote 955 hexedit, an interactive hex editor that implements the start of 956 cursor control infrastructure (for eventual use by less and vi and shell 957 command history and so on).</p> 958 959 <p><b>New options:</b> Added sed -E as a BSD-compatible synonym for -r. 960 Upgraded oneit with -r (restart), -3 (send exiting PID values to child), 961 and signal handling. Added -v option to timeout, -m to mknod, -u to shred, 962 -t to dmesg, and -123 to head and tail. Added implicit "." to grep -r without 963 any files to work on. Hyejin Kim requested prefix support for truncate -s. 964 Greg Hackman added -inum to find. 965 Jan Cybulski added the smack side of ls -Z support. Various patches also 966 added -Z to mkdir, mknod, and mkfifo. 967 Basic cp --preserve support went in, but not yet the xattr/LSM parts.</p> 968 969 <p>The toybox command now has a --version option, 970 which uses "git describe" if available.</p> 971 972 <p><b>Build infrastructure:</b> 973 The "make change" target now saves the output of each failed standalone 974 command build in a .bad file, and "make defconfig" is quieter now.</p> 975 976 <p>Paul Barker submitted a large patch changing command install paths so 977 "toybox can be installed alongside busybox without confusing 978 update-alternatives". (There's some argument over 979 what the right paths should be, and I'm waiting for 980 people to tell me what else needs fixing because I have no idea. I've 981 been symlinking /bin to /usr/bin since 2002 982 <a href=http://landley.net/writing/hackermonthly-issue022-pg33.pdf>for 983 historical reasons</a>.)</p> 984 985 <p><b>Docs:</b> The repository link now goes to github, with another link 986 to the commit rss feed.</p> 987 988 <p>Elliott Hughes updated the Android section of the roadmap 989 (and he would know). Redid bits of scripts/mkstatus.py to make updating 990 status.html easier, and the README is larger.</p> 991 992 <p>More description of option parsing in code.html, which now describes the 993 FLAG_x macros, switching flag macro sets with FOR_newcommand, how 994 configuration zeroes flag macros and using FORCE_FLAGS to suppress the 995 zeroing of options shared between commands. Also added description of ";" 996 to make --longopts take an optional =value part, and more about TOYBOX_DEBUG 997 to check NEWTOY() option strings (otherwise a bad option string makes 998 lib/args.c obviously segfault, but doesn't explain why).</p> 999 1000 <p>Added a "Why 0BSD?" section to license.html when submitting zero clause bsd 1001 to SPDX (according to the pending license spreadsheet, it's been approved for 1002 SPDX 2.2).</p> 1003 1004 <p>The old list of commands needing cleanup but not in pending was 1005 removed from toys/pending/README and instead the issues were added 1006 as TODO comments in the individual commands.</p> 1007 1008 <p><b>Bugfixes:</b> 1009 Fixed mount -a segfaulting without -O (reported by Janus Troelsen), 1010 and made it try a "become rw" ioctl() on the block device before falling 1011 back to mounting read only (because Android expects that). 1012 Fixed printf -- and printf ---. Lots of tweaks to ls -l spacing with 1013 different options. Make touch -d and -t actually set time when you don't 1014 specify nanoseconds. 1015 Fixed a subtle bug where recursive calls (toybox commands that run other 1016 toybox commands) weren't resetting all their state. (This manifested as 1017 a "no }" error from "find | xargs sed", but could cause other problems.) 1018 And David Halls reported another sed bug trying to compile libiconv (which 1019 left extra \ at the start of lines in a generated shell script, breaking 1020 the build). Output an error message for "cat /mnt".</p> 1021 1022 <p>Kylie McClain reported that mktemp broke when $TMPDIR was set to an empty 1023 string (which is not the same as unset), that install/find didn't support 1024 numeric uid/gids, and that sort -z affects both input and output. 1025 Isabella Parakiss fixed a printf.c bug. 1026 David Halls fixed bugs in install -D and find -exec. Samuel Holland 1027 fixed unshare -r. Hyejin Kim fixed makedevs with a count of 1, fold -w 1028 range checking, an error path in scripts/mkflags.c, added -i to dhcpd, 1029 and stopped su from prompting the root user for the new user's password. 1030 Jan Cybulski spotted wrong indentation when combining ls -s and -i with -C and 1031 -x. Jos Bollo fixed stat %G. Sameer Pradhan fixed a bug in mkfifo -Z.</p> 1032 1033 <p>Elliott Hughes asked for a default SIGPIPE handler to disable 1034 the signal handler bionic's dynamic loader installs (yes really). Still not 1035 100% sure what the correct behavior is there. (Posix is 1036 (<a href=http://permalink.gmane.org/gmane.comp.standards.posix.austin.general/10915>actively unhelpful</a>, but at least they're taking 1037 <a href=http://austingroupbugs.net/view.php?id=789#c1976>years to 1038 make up their mind</a>. Elliott also sent patches to fix a typo in 1039 useradd.test, add missing arguments to error_exit() calls and clean up 1040 printf() format strings, fix an off by one error in human_readable(), 1041 fix dmesg -c error reporting, fix a segfault in comma_scan where the option 1042 was the last item in optlist (triggered by mount -o ro,remount), fix 1043 hwclock -w, made ifconfig print lowercase MAC addresses (it was bothering 1044 him), and make terminal_size() read the right environment variable 1045 (LINES, not ROWS). And he suggested the test suite notice high command exit 1046 values (corresponding to segfault or other signals).</p> 1047 1048 <p>People are apparently using toys/pending commands, despite the police tape 1049 and flashing lights, so added louder warnings to toys/pending/README. 1050 Elliott Hughes fixed various problems with tar, dd, more, and top. 1051 Hyejin Kim cleaned up syslogd and dumpleases. Isaac Dunham added hotplug 1052 support to mdev. Yeongdeok Suh added RFC-3315 ipv6 support to dhcpd.</p> 1053 1054 <p>I rewrote ps.c from scratch (in pending), but it's not ready for real use 1055 yet.</p> 1056 1057 <p><b>Portability:</b> 1058 On the portability front Bernhard Rosenkranzer fixed a problem where the 1059 menuconfig code wouldn't compile in C99 mode. (This led to me documenting 1060 the craptacular nature of kconfig in a README, and the plan to replace it 1061 sometime before 1.0.) Some extra flags to shut up overzealous llvm warnings 1062 were added (and have to be probed for because gcc complains about 1063 arguments it doesn't recognize even when they switch stuff _off_ using 1064 a standard syntax). Don't depend on malloc(0) to return non-null in ls. 1065 David Halls fixed some mac/ios portability issues, 1066 implying somebody's built at least part of toybox on a mac.</p> 1067 1068 <p>Added basename_r() to lib/lib.c because the posix semantics for basename() 1069 are stupid but what the gnu guys did to it was appalling. 1070 Turns out bionic already had a basename_r(), but posix still doesn't. 1071 Fixed it up in portability.h, but this 1072 could break more stuff in future. (Correct fix is to lobby posix to add it, 1073 which would probably take about 15 years...)</p> 1074 1075 <p><b>Infrastructure:</b> 1076 The build now checks $LDFLAGS for linker-only flags, and allows the strip 1077 command to fail (binflt toolchains provide a strip that doesn't work). 1078 Since time.c uses floating point, added TOYBOX_FLOAT dependency in config.</p> 1079 1080 <p>There's a lib/lsm.h defining varous inline functions for linux 1081 security modules stuff, if (lsm_enabled()) should turn into a compile-time 1082 constant 0 and let code drop out when TOYBOX_LSM_NONE selected, but 1083 testing against CFG_TOYBOX_LSM_NONE or derived symbols is still useful 1084 becuase when it _is_ enabled the probe turns into a system call you 1085 don't want to repeat too much.</p> 1086 1087 <p>Switched a bunch of commands from signal() to xsignal(). Factored out 1088 xgetgrnamid() and xgetpwnamid() into xwrap.c. Make time.c depend on 1089 TOYBOX_FLOAT (since it always uses float so shouldn't be available on 1090 build targets without even software float). Added readfileat() to lib/lib.c.</p> 1091 1092 <p>The dirtree infrastructure now passes in full flags for the old symlink 1093 field, and the new DIRTREE_SHUTUP flag disables warnings if a file vanishes 1094 out from under you during traverse. New dirtree_start() wrapper to 1095 create dirtree root with only two arguments.</p> 1096 1097 <p>The not-curses infrastructure introduced by hexedit mostly moved to 1098 lib/interestingtimes.c.</p> 1099 1100 <a name="asterisk" /> 1101 <a href="#asterisk_back" />Asterisk:</a> such when 1102 Tim contacted me (my blog says a couple days before nov 13, 2011, I.E. 1103 11/11/11 not some specific day 2 months later) to ask if I wanted to work 1104 on a new project he was proposing called 1105 <a href=http://www.elinux.org/Busybox_replacement_project>BentoBox</a> 1106 (because I used to do busybox, he'd forgotten toybox existed 1107 until I brought it up). And don't ask me what "focuses not on compatibility 1108 with its GNU counterparts" means when CP_MORE adds 7 non-posix options 1109 and toys/other has 84 commands in neither posix nor LSB. I think they're 1110 struggling to explain the difference having dismissed "licensing" as being 1111 the reason it started up again after a long hiatus? The reason I don't think 1112 GNU is special is there are a half-dozen other independent 1113 implementations of the same unix command tools out there (AT&T, 1114 BSD, Coherent, Minix, plan 9, busybox, toybox, and several more analyzed in 1115 the <a href=roadmap.html>roadmap</a>, and that's ignoring the implementations 1116 written for DOS or in assembly over the years). But I do care what 1117 Linux From Scratch expects, and if it's 1118 <a href=http://archive.linuxfromscratch.org/lfs-museum/7.6/LFS-BOOK-7.6-NOCHUNKS.html#ch-tools-gcc-pass1>calling mv -v</a> 1119 then I impelement mv -v 1120 even if <a href=http://landley.net/toybox/roadmap.html>posix hasn't got 1121 it</a>. And I don't know why "gnu counterparts" would describe this when 1122 util-linux isn't a gnu package, nor are info-zip, e2fsprogs, kmod, less, 1123 procps, shadow, sysklogd, vim, zlib, sudo, dhcpcd...</p> 1124 1125 <a name="05-04-2015" /><a href="#05-04-2015"><hr><h2><b>April 5, 2015</b></h2></a> 1126 <p>Since <a href=https://android.googlesource.com/platform/external/toybox/>android</a> and 1127 <a href=https://git.tizen.org/cgit/platform/upstream/toybox.git>tizen</a> 1128 and <a href=https://github.com/kraj/meta-musl/tree/master/recipes-core/toybox>openembedded</a> 1129 and <a href=https://packages.gentoo.org/package/sys-apps/toybox>gentoo</a> 1130 and so on have all been using Georgi Chorbadzhiyski's git mirror rather 1131 than the mercurial repository, I bit the bullet and switched the project's repo 1132 <a href=https://github.com/landley/toybox>to git</a>.

On toybox's end this 1151 involved a lot of fixups to portability.[ch] and fixes to over a dozen 1152 commands, plus several new ones. Other portability fixes included working 1153 with buildroot's uclibc fork and building for nommu targets.</p> 1154 1155 <p>The new "make change" target builds each toybox command as a standalone 1156 binary. Rather a lot of commands that didn't build by themselves (mv depending 1157 on cp and so on) were hit with a large rock until they built standalone. 1158 This involved rewriting bits of option parsing, more elaborate dependency 1159 generation, making each command have its own config 1160 symbol and main() function (even when it's just a wrapper calling another 1161 command's main()), and so on. Also, some commands can't be built standalone 1162 at a conceptual level: "help" describes other enabled commands and "sh" 1163 has a number of bulitin commands (cd, exit, set) that require the 1164 multiplexer infrastructure, so "make change" filters them out.</p> 1165 1166 <p>The mailing list's web archive is still screwed up. Dreamhost has 1167 been trying to fix it since approximately September. There are 1168 <a href=http://www.mail-archive.com/toybox@lists.landley.net/>two</a> 1169 <a href=http://news.gmane.org/gmane.linux.toybox>other</a> less broken 1170 archives, but neither has quite the same UI as mailman.</p> 1171 1172 <h3>Bugfixes and tweaks</h3> 1173 1174 <p>Cynt Rynt sent in tests for ifconfig, 1175 Robert Thompson taught factor to accept whitespace separated arguments, 1176 Hyejin Kim pointed out that some of mktemp's longopts were attached to 1177 the wrong short options, 1178 Luis Felipe Strano Moraes fixed a wrong free() call in bootchartd in pending. 1179 Patches from Ashwini Sharma to make "df /dev/node" work, prevent du from 1180 looping endlessly following symlinks, and to make expr.c 1181 (in pending) understand == and regex matches. (Speaking of expr, it gets 1182 priority groupings wrong but the bug was actually in the posix spec's 1183 HTML conversion. They fixed the posix spec upstream for us. Still need 1184 to fix the expr code, but it's in pending for a reason...)</p> 1185 1186 <p>Some commands grew new option flags, such as cp --remove-destination 1187 and touch -h.</p> 1188 1189 <p>The parallel build has better error reporting now. When toybox needs to 1190 re-exec itself to regain suid root permissions and hasn't got the suid bit, 1191 it now gives the right error message ("not root" instead of "no such command"). 1192 1193 <p>Added a test to "mount" to not mount the same device/directory combination 1194 over itself (the OS catches this for block devices, but not for tmpfs). 1195 Make blkid distinguish ext3 from ext4. Added catv back into cat (because 1196 the Android guys wanted it, and they have historical usage on their side, 1197 so...). Handle nanoseconds in touch.</p> 1198 1199 <p>Fixed a segfault when CP_MORE was disabled (the resulting option flag list 1200 no longer defined -d but still had it in option groups at the end). 1201 Workaround for glibc redefining dirname() and basename() to random non-posix 1202 semantics because gnu. (They could have created dirname_r() but didn't want 1203 to.)</p> 1204 1205 <p>Fix an ifconfig test that was preventing assigning an ipv4 address to 1206 interface aliases. Several cleanup passes on hwclock but not quite 1207 promoted out of pending yet.<p> 1208 1209 <p>Fixed a wrong error message in rm (if you had a chmod 000 directory and 1210 did rm -r on it without -f, after the prompt it would complain it was a 1211 directory, which was not the problem).</p> 1212 1213 <p>The gzip compression code now does "store only" output to stdout, for 1214 what that's worth.</p> 1215 1216 <p>Cleanup mountpoint and expand, and remove them from toys/pending/README 1217 (a list of commands that predate the toys/pending directory but needed 1218 another pass).</p> 1219 1220 <h3>Library and infrastructure:</h3> 1221 1222 <p>Reworked the option parsing infrastructure so more commands build 1223 standalone (via scripts/single.sh or "make change"). The option flag bit 1224 values are no longer packed, it leaves spaces where currently disabled 1225 flags go, and you can #define FORCE_FLAGS so disabled flags aren't zeroed. 1226 This allows multiple commands to more easily share infrastructure, even if 1227 your current flag context is for a disabled command (switched off in config), 1228 you can force them to stay on and as long as the flags read the same right 1229 to left they'll have the same values.</p> 1230 1231 <p>We've started removing use of strncpy() because it's a hugely broken 1232 standard C function: the length is the maximum length to _append_, not 1233 the size of the destination buffer. It memsets the remaining space it didn't 1234 copy ala "memset(dest+strlen(dest), 0, len);" so 1235 if you think len is the size of dest you're guaranteed to stomp memory off the 1236 end). And if it runs out of space it won't null terminate because reasons. 1237 (Meanwhile sprintf("%*s", len, str) is counting wide characters in your current 1238 locale, so if you set a locale other than "C" it will also go past your 1239 allocated buffer size. Whoever is maintining the C library standards is really 1240 bad at strings.) 1241 Instead we have xstrncat() which will error_exit() if src+dest+1 doesn't 1242 fit in the buffer.

Cynt Rynt spotted an 1326 unnecessary assignment in lib/password.c.</p> 1327 1328 <p>Ashwini Sharma's team was as busy as usual, submitting tr, crontab, and 1329 ipcrm, and hwclock to pending, more features to the pending ip.c, and a 1330 pile of bugfixes (to chgrp, killall, ifconfig, insmod, 1331 losetup, comm, cp, id, xwrap, netcat, modprobe, nohup...) mostly found by 1332 static analysis. (These fixes are mostly to seldom-used codepaths like the 1333 TOYBOX_FREE config option, but test coverage is always appreciated.) Ashwini 1334 also suggested upgrading ln -f to leave the original target alone if link 1335 creation fails, and reported that mv -f and -i weren't implemented (now fixed).</p> 1336 1337 <p>New config option: TOYBOX_NORECURSE prevents xexec() from making internal 1338 function calls (for nommu systems with a finite stack).</p> 1339 1340 <p>The "toybox" multiplexer command no longer adds a trailing space to each 1341 line of command names, so things like "./toybox | tr ' \n' '|'" to create 1342 a grep pattern snippet are easier to do. (Why you'd want to is your business, 1343 but the output is tidier now.)</p> 1344 1345 <h3>Infrastructure</h3> 1346 1347 <p>Isaac Dunham added Android support to portability.h, including compile 1348 probes for functions missing from bionic-libc, and annotated the commands that 1349 use those functions.

(And in case you missed it last time, VERBOSE=fail 1354 to stop at the first failure is really useful.)</p> 1355 1356 <p>In loopfiles_rw() use O_CLOEXEC instead of O_RDONLY to request the loop 1357 function close filehandles for us.

Other minor cleanups happend to 1381 cut, touch, free, and id.</p> 1382 1383 <p>In pending: Bradley Controy submitted mix (adjusts OSS sound volume).

(Export the environment variable CPUS to pick a specific number.) 1394 Other build changes: split out $LDOPTIMIZE because old compilers complain 1395 about linker options passed with -c, and the entire "generated" directory now 1396 gets deleted by clean (the README that was in there got merged into code.html).</p> 1397 1398 <p><b>Standalone builds</b></p> 1399 1400 <p>The standalone build infrastructure (scripts/single.sh) got upgraded to 1401 build more commands as standalone executables. In make.sh the source file 1402 selection uses a regex to find the source files with the NEWTOY/OLDTOY macro 1403 for the command. It enables each command's 1404 sub-options (so CP has CP_MORE), enables I18N and FLOAT support to build 1405 full-featured commands, and includes --help text (at least when 1406 the command doesn't use another command's help). The OLDTOY() macro 1407 now produces (redundant) function prototypes so you can build an OLDTOY 1408 without the NEWTOY</p> 1409 1410 <p>It doesn't quite have complete coverage yet, the defconfig entries that 1411 aren't building standalone yet are:</p> 1412 1413 <blockquote><p>chown, egrep, fgrep, fstype, halt, mv, nc, poweroff, unix2dos, 1414 whoami</p></blockquote> 1415 1416 <p>The main reason for standalone build failures is NEWTOY() or OLDTOY() 1417 entries that don't have their own config symbol. Another problem is entries 1418 that depend on another entry in kconfig, usually because common infrastructure 1419 is using one command's flags (which the other commands copy): if that command 1420 is disabled, the FLAG macros become 0 so dead code elimination can remove the 1421 code. It's <a href=http://landley.net/hg/toybox/rev/1503>possible 1422 to untangle</a> this, but a bit awkward. (It boils down to conflicting 1423 design goals in the two contexts.)</p> 1424 1425 <p>Standalone builds are used by the test suite when testing individual 1426 commands. 1427 1428 <p><b>Snapshot builds</b></p> 1429 1430 <p>A new addition to the "generated" directory is generated/build.sh 1431 containing a single compiler command line to build toybox in its current 1432 configuration. Combined with the generated/*.{h,sh} files from an 1433 exisiting build, this may let you build on a new system that hasn't quite 1434 got enough OS bits working to run a full configureand make.</p> 1435 1436 <h3>Internals</h3> 1437 1438 <p>Library code: xcreate/xopen now O_CLOEXEC by default to avoid leaking 1439 filehandles to child processes. DIRTREE_COMEAGAIN's second callback is now 1440 done with the directory filehandle still open (new dir->again variable added 1441 to distinguish first from second callback, and requesting DIRTREE_RECURSE now 1442 requires passing in the specific macro value, not just a true/false). 1443 Use daemon() out of libc instead of hand-rolled daemonize() in various 1444 pending commands. string_to_mode() now passes through type bits so you can 1445 use it to more easily modify a file's existing mode. 1446 Split xpopen() into xpopen_both(), xopen(), and xrun() depending on whether 1447 we want to redirect both, one, or neither of stdin/stdout.</p> 1448 1449 <p>Bugfixes: Better error message when TOYBOX_SUID option can't drop priviliges 1450 (which happens when you suid something _other_ than root). 1451 The old pending version of nbd_client.c wasn't deleted when the 1452 command was promoted (and the build would break if both were enabled), 1453 toy_exec() sometimes needs to re-exec from $PATH rather than recurse 1454 internally (to gain dropped root permissions or limit stack depth), 1455 always call setlocale() when I18N is enabled to switch it back _off_ when 1456 we run commands that expect sscanf("%n") to return bytes, 1457 dirtree() had a memory leak in an error path, patch.c had some bugs in 1458 error paths (didn't report problem clearly). Ashwini Sharma spotted an 1459 option parsing bug where [-abc] would forget _all_ command line arguments 1460 saved in the GLOBALS() block (not just the ones for options being switched 1461 off), plus various minor fixes to nbd_client and cpio. 1462 Lukasz Szpakowski fixed rm -f on a broken symlink (failed), and killall 1463 with no arguments (segfaulted).</p> 1464 1465 <p><b>Portability</b></p> 1466 1467 <p>A somewhat fiddly fix to rm -rf (which needs to chmod directories to u+rwx 1468 to descend into them) which hit a musl bug in faccessat() which the musl 1469 maintainer refuses to fix. (He literally wants the man page changed 1470 instead, despite other libcs working.) Added an #ifdef __MUSL__ section 1471 to portability.h with a workaround, you may need CFLAGS=-D__MUSL__ in your 1472 build if your musl build's features.h doesn't #define that. (I may do 1473 a different workaround in future, but sometimes you've just got to make 1474 it work so you can ship. Also, toybox grep with multiple patterns 1475 requires <a href=http://landley.net/hg/aboriginal/rev/1692>a patch 1476 to musl's regex engine</a>, which applies to 1.1.4 but not to the current 1477 musl source control.)</p> 1478 1479 <p>More portability.h fixes for uClibc too. (I don't expect that to ever have 1480 another release, so locally patching around posix-2008 violations is silly).</p> 1481 1482 <p><b>Change to username filtering</b></p> 1483 1484 <p>Posix recommends the username creation logic filter usernames to a small 1485 allowed set of characters (which even Red Hat breaks by explicitly allowing 1486 "$" at the end), but this prevents UTF-8 usernames. Posix' stated logic 1487 is to allow filesystems to create the user's home directory, but Linux 1488 filesystems can accept any character but NUL and "/". The only characters 1489 we actually _need_ to filter out are ":" (field separator in passwd), 1490 newline (line separator in passwd), and "/" (directory separator in 1491 filesystem).</p> 1492 1493 <h3>Documentation</h3> 1494 1495 <p>Web pages updated: cleanup.html documents more cleanup, code.html 1496 documents more code, and about.html now capitalizes "toybox" consistently 1497 (it's just a word, capitalize at start of sentence).</p> 1498 1499 <p>The pending/README file now lists commands that needed review/cleanup 1500 before the pending directory was added.</p> 1501 1502 <h3>Test Suite</h3> 1503 1504 <p>Moved out of scripts/test into top level "tests" directory, and the 1505 testing.sh script is now in scripts rather than mixed into the *.test files.</p> 1506 1507 <p>Johan Bergstrm requested VERBOSE=fail to make tests (telling it to 1508 stop at the first failure), and spotted a build bug where using gnu 1509 sort on the host broke in non-C locales.</p> 1510 1511 <p>Divya Kothari submitted tests for chmod, link, tar, bzcat, xzcat, zcat, 1512 and hostname.

(Not a show 1548 stopper for incoming 1549 contributions, just an explanation of some of the things I'll do to them 1550 during cleanup.)

Make the "we are not root" test 1570 in the init code show the help text. Posix implies that fflush() can return 1571 success even when the stream's error bit is set, so call both fflush() and 1572 ferror() from xprintf().</p> 1573 1574 <p>Isaac Dunham pointed out that bloatcheck couldn't deal with diff 1575 implementations that only implement "unified diff" format, and that some 1576 diff implementations can't handle nonseekable input (I.E. reading from 1577 a pipe). Bugfix so "help -a" works again. Option parsing on nohup now stops 1578 at first nonoption argument. Fix segfault in "which" if PATH wasn't set, 1579 which was actually a bug in lib function find_in_path(). Made rm -rf of 1580 chmod 000 directories actually remove them.</p> 1581 1582 <p>The build now passes the same $CFLAGS to the library probe as the final 1583 build, because arch linux is so broken it provides different sets of 1584 libraries for static and dynamic linking.</p> 1585 1586 <p>It turns out sprintf("%.123s", str) is counting characters, not bytes, 1587 so globally enabling locale support opens stack smashing vulnerabilities. 1588 So there's a new TOYFLAGS_LOCALE you set in toyflags when you want the 1589 setup code to setlocale().</p> 1590 1591 <p><b>Upgrades:</b></p> 1592 1593 <p>Isaac Dunham extended cpio to archive unreadable empty files, and I taught it 1594 to set uid/gid and timestamp when extracting archives. Isaac also 1595 added tests for cpio, link, and du, added lspci -i, made the pci database 1596 parsing skip # comment lines, merged logname and whoami into id.</p> 1597 1598 <p>Daniel Verkamp sped up md5sum about 30% with some loop unrolling, making 1599 it actually smaller in the process. I added -b flags to md5sum and sha1sum 1600 for "brief" output that's just the hash with no filename. (I'm aware other 1601 implementations use that for MSDOS "binary" mode, and don't care.)</p> 1602 1603 <p>When building standalone commands (scripts/singleconfig.sh commandname), 1604 the build now switches on all the sub-options of the command so we get 1605 a standalone version with all the bells and whistles enabled.</p> 1606 1607 <p>Add -ds flags to date and document +FORMAT escapes. Add the shell NOP 1608 command ":" as an alias for true (for toysh).</p> 1609 1610 <p>Add uClibc probe for iconv() and fallocate. (The fact it didn't always 1611 build against uClibc is why fallocate wasn't enabled in defconfig before.)</p> 1612 1613 <p>The umount command now does an losetup -d on the device by default, so 1614 we don't leak loopback devices. Bugfix to losetup so "losetup /dev/loop0 1615 filename" actually works again.</p> 1616 1617 <p>Divya Kothari sent in test suite entries for ls, ln, rm, mv, printf, dd, 1618 and renice. Then a second round for lsattr/chattr, mount, chmod, pgrep/pkill, 1619 groupadd, groupdel, and useradd. Several of these uncovered bugs, still 1620 working to fix them.</p> 1621 1622 <p>There are now free() functions for the predefined llist types and a 1623 dlist_terminate() function to break doubly linked lists. The new 1624 generic_signal() handler either sets "toys.signal" or writes a byte 1625 to toys.signalfd with the signal number if signalfd isn't -1 (which it's 1626 initialized to in toy_init).</p> 1627 1628 <p>The option parsing logic can now detect when a double fits in a long and 1629 use the more precise type for floating point arguments (the FLOAT macro 1630 contains the type used). The human_readable() function now just outputs 1631 decimal kilo/mega/gigabytes (so when du -u says 5.0G it means 5.0 billion 1632 bytes). The build infrastructure now notices duplicate commands (so if you 1633 cp toys/pending/command.c toys/other/command.c and forget to delete the 1634 first one, the build break is now more informative).</p> 1635 1636 <a name="20-04-2014" /><a href="#20-04-2014"><hr><h2><b>April 20, 2014</b></h2></a> 1637 <blockquote><p>And to this end they built themselves a stupendous supercomputer 1638 which was so amazingly intelligent that even before the data banks 1639 had been connected up it had started from "I think therefore I am" and got as 1640 far as the existence of rice pudding and income tax before anyone managed to 1641 turn it off. - The Hitchhiker's Guide to the Galaxy.</p></blockquote> 1642 1643 <p><a href=downloads/toybox-0.4.8.tar.bz2>Toybox 0.4.8</a> is based on 1644 <a href=http://landley.net/hg/toybox/shortlog/1262>commit 1262</a>.

Samuel Holland submitted fold. 1662 I wrote a new inflate (zip/zlib/gzip decompression) implementation in 1663 compress.c, and still need to do a corresponding deflate (compression-side) 1664 and plug them into gzip and zip and so on. (Right now it does zcat.)</p> 1665 1666 <p>Several commands (vmstat, login, du, vconfig, mountpoint, free, chroot, 1667 cut, touch, modinfo, expand) predate the "pending" directory, and are thus 1668 in other directories but still need cleanup. Of these, vmstat got some 1669 work this time (which would be much easier other vmstat implementations 1670 documented what their output actually meant).</p> 1671 1672 <p><b>Upgrades:</b> Ifconfig grew /prefix netmask support (ala 1.2.3.4/24). Grep now has -zZ to 1673 handle null terminated data, cksum grew -H for hex output. Upgraded od so the 1674 fields align better when producing multiple output types. Help has -a and -h 1675 options (all commands, html output). 1676 Bugfix to blkid building for a 32 bit target. The date command can actually 1677 set dates now. The O_NOFOLLOW compile time probe didn't work with cross 1678 compiling, so it's back to an #ifdef test in portability.h. Nathan McSween 1679 sent in a bugfix to od and a portability fix in the common library code. 1680 Ashwini Sharma spotted a bug in pidof -o, and added verbose (-v) options 1681 to mkdir and ln, and suggested killall should have an -s option and 1682 allow -l to take zero arguments. Ashwini Sharma and Felix Janda upgraded 1683 tftpd. Fixed dumpleases still using toynet.h after 1684 that was removed. Corrected killall return code and error reporting. 1685 Isacc Dunham fixed bugs all over the tree, did cleanup on a bunch of 1686 pending commands (getty, ftpget, init, openvt, modprobe...), and clarified 1687 find's help text. Tom Sparrow ran three different static analyzers on 1688 the code, which resulted in a few cleanups. The peek()/poke() functions 1689 now use "volatile" to prevent broken compiler "optimizations" to do with 1690 aliasing.</p> 1691 1692 <p><b>Build stuff:</b> Each FOR_xxxx macro now has a complementary CLEANUP_xxxx macro, so you 1693 can put multiple commands with different command line options in the same 1694 .c file, so they can share infrastructure outside of lib. (This let the 1695 bunzip logic move out of lib into bzcat.c.) See XXX for example. 1696 i 1697 <p>The headers #included in toys.h are now grouped by standard, and headers 1698 not listed in Posix or LSB were moved to portability.h. The old xregcomp.h 1699 was folded into lib.h because it's posix (and supporting oddball uClibc 1700 configurations isn't as important as it once was).</p> 1701 1702 <p>Regression tested against Ubuntu 8.04 to fix up bit-rot in defconfig 1703 build on older systems. (We depend on Posix-2008, but not necessarily 1704 the absolute latest build environment.)</p> 1705 1706 <p><b>In lib</b>: lib/xwrap.c added xgetpwnam(), xchroot(), and lib/lib.c now has names_to_pid(). 1707 xsetuid() was replaced with xsetuser() which takes a struct passwd 1708 and sets both gid and uid, mkpathat() got factored out into a library command, 1709 get_int_value() became atolx_range(), and 1710 xmsprintf() is now just xmprintf(). The bunzip2 logic moved from lib into 1711 bzcat.c.</p> 1712 1713 <p><b>Documentation</b>: new <a href=help.html>help page</a> with the 1714 help text for all the defconfig commands, using the new help -ah output. 1715 The <a href=code.html>source code walkthrough</a> now says more about 1716 #including header files, and how the generated/* directory works. The 1717 <a href=design.html>design page</a> has some new paragraphs about trading 1718 of different kinds of simplicity, and why comments aren't a substitute for 1719 good code. The README no longer trails off into obvious unfinished confusion 1720 at the end. Each page on the website should now have its own title.</p> 1721 1722 <a name="18-11-2013" /><a href="#18-11-2013"><hr><h2><b>November 18, 2013</b></h2></a> 1723 <blockquote><p>"Space," it says, "is big.

Elie De Brauwer submitted 1730 reboot, halt, and poweroff. Strake's nl got cleaned up and promoted from 1731 pending to posix. In addition, the existing chvt and vconfig got some 1732 cleanup.</p> 1733 1734 <p>That said, I haven't nearly kept up with the flood of new commands going 1735 into pending: Ashwini Sharma's team submitted 1736 dd, dumpleases, traceroute, top, useradd, groupadd, mkpasswd, tftpd, and 1737 an fsck wrapper (with no filesystem drivers yet). Isaac Dunham sent in cpio.</p> 1738 1739 <p>Bugfixes: Jeroen van Rijn added a user count to uptime. Elie De Brauwer 1740 added -e to watch, removed a memory leak, and fixed a terminal size problem. 1741 William Haddon made xargs call its command line once even with blank input 1742 (the standard is vague, but builds expect it), and fixed an off by one bug 1743 where grep didn't malloc enough space with -E (leading to a segfault). 1744 I fixed a glitch in bunzip2 (same one as went into busybox since they're using 1745 the code I wrote), in od to fix -t co, -J, and -c options. Add uname -o as a 1746 synonym for -s. Build fix to never use $CC without prefixing it with 1747 $CROSS_COMPILE (since $HOSTCC could be different). Anca Emanuel spotted 1748 a typo in the web page.</p> 1749 1750 <p>The compile-time command line option parsing got rewritten (ported from 1751 bash to C), which should speed up builds a bit and allow code controlled by 1752 --longopts to drop out properly when disabled in the configuration. Terminal 1753 querying got refactored. Patch's -x option is now more informative (a 1754 debug thing if you're trying to figure out why a patch didn't apply). 1755 The "toynet.h" file got folded into toys.h since musl supports it and 1756 micromanging uClibc options isn't very interesting anymore. The test suite 1757 now uses scripts/single.sh when testing a single command.</p> 1758 1759 <a name="17-09-2013" /><a href="#17-09-2013"><hr><h2><b>September 17, 2013</b></h2></a> 1760 <blockquote><p>"Think of a number," said the computer, "any number." 1761 Arthur told the computer the telephone number of King's Cross railway 1762 station passenger inquiries, on the grounds that it must have some function, 1763 and this might turn out to be it. - The Hitchhiker's Guide to the Galaxy</p> 1764 </blockquote> 1765 1766 <p><a href=downloads/toybox-0.4.6.tar.bz2>Toybox 0.4.6</a> is based on 1767 <a href=http://landley.net/hg/toybox/shortlog/1068>commit 1068</a>.</p> 1768 1769 <p>This release adds 1770 several new commands: Felix Janda wrote paste and fallocate, Kyungwan Han 1771 submitted eject, Strake contributed grep, Ashwini Sharma added pmap (and 1772 a testsuite entry for grep), Lukasz Skalski sent pwdx, Isaac Dunham posted 1773 acpi, and I did timeout and umount.</p> 1774 1775 <p>The ls command now has a --color=auto option (suggested by Rich Felker). 1776 The multiplexer now has a --help option so you can say "./toybox --help blah" 1777 instead of using the built-in "help" command. (Which is a shell built-in. 1778 Try it on your command line, it's like man for shell builtins. But a certain 1779 other project has conditioned people to expect --help, so...)

We've got klogd, 1787 dhcp, dhcpd, watch, route, and ps from 1788 Ashwini Sharma (and an fsck wrapper but no fsck.fstype engines yet), 1789 syslogd, pgrep, and pkill from Madhur Verma, netstat by Ranjan Kumar, 1790 test by Felix Janda, lspci by Isaac Dunham, nl, su, and renice by strake (I.E. 1791 M. Farkas-Dyck), and sysvinit by Kyungwan Han.</p> 1792 1793 <p>Some cleanup work on existing pending commands that aren't 1794 ready to promote yet: I did a few more rounds on ifconfig 1795 and Isaac Dunham's did several cleanups to xzcat, Felix Janda cleaned up 1796 logger and syslogd...</p> 1797 1798 <p>Also some cleanup work on commands that predate the pending directory, 1799 but weren't quite polished when they went in, most prominently du, 1800 expand, and touch.</p> 1801 1802 <h3>Infrastructure</h3> 1803 1804 <p>The new scripts/single.sh builds a standalone command without the 1805 multiplexer, although not all commands can be built that way yet (NEWTOY yes, 1806 OLDTOY no) and the space savings aren't anything to write home about. (If a 1807 command needs the option parsing logic at all, it needs all of it.) If 1808 you're curious, you can do:</p> 1809 1810 <blockquote><pre> 1811 make defconfig 1812 make 1813 mkdir singles 1814 for i in $(./toybox) 1815 do 1816 echo $i 1817 PREFIX=singles/ scripts/single.sh $i || break 1818 done 1819 </pre> 1820 <p>(And then wait a long time and watch almost half the builds fail.)</p> 1821 </blockquote> 1822 1823 <p>There is now libbuf analogous to toybuf, another global 4k buffer this 1824 time for use by lib/ code instead of command code.</p> 1825 1826 <p>The lib directory got split up a bit, lib/pending.c contains functions 1827 not yet used by anything outside of toys/pending/*, and lib/xwrap.c contains 1828 functions that wrap other functions and handle failures (via error_exit). 1829 This leaves lib/lib.c containing actual new functions.</p> 1830 1831 <p>General improvements and bug fixes to argument parsing. The [-abc] exclude 1832 logic should now clear arguments slots when disabling options. Bare --longopts 1833 should work now and be able to report errors using their name, the new ; 1834 option allows optional arguments to longopts only suppliable with = (I.E. 1835 --color and --color=auto but not --color auto).</p> 1836 1837 <p>I'm gradually weaning the code off of itoa()/utoa() because sprintf 1838 does this already. In this case "simple" probably means "let libc do it 1839 for us".</p> 1840 1841 <p>Rewrote for_each_pid_with_name_in() and renamed it to just names_to_pid(). 1842 It shouldn't get confused trying to compare absolute and relative paths quite 1843 so much anymore.</p> 1844 1845 <p>lib/llist.c grew a new dlist_pop() function for removing a doubly 1846 linked list entry while maintaining a circular list; tail and patch are 1847 using it now.</p> 1848 1849 <p>The musl guys suggested a new optimization flag 1850 (-fno-asynchronous-unwind-tables) 1851 that shaves about 10% off the binary size by removing a C++ism that crept 1852 into gcc's idea of C. While I don't normally try to micromanage the compiler, 1853 "-fstop-being-stupid" is a thing you have to hit gcc with from time to time.</p> 1854 1855 <h3>Bugfixes</h3> 1856 1857 <p>Felix Janda and I did a largeish rewrite of tail to 1858 finally make it work right (we think). Still need to implement tail -f 1859 someday (the tricky bit is making -f follow multiple files at once). 1860 Felix also reported a bug in xpidfile.</p> 1861 1862 <p>Juhani Haverinen pointed out that 1863 python 3 doesn't work with config2help.py, so the detection logic looks 1864 for python2 (until I get around to rewriting that in C). Elie De Brauwer 1865 then fixed our first attempt at this, and also fixed uname's help string.</p> 1866 1867 <p>Ashwini Sharma 1868 pointed out the build was making a FLAG_ macro for " " which broke some 1869 configurations. (That's a control character, not a command line option.)</p> 1870 1871 <p>Jacek Bukarewicz pointed out a bug in chdir permission handling, and 1872 a way to make env segfault. Both should be fixed now.</p> 1873 1874 <p>The new function xexec_optargs() 1875 replaces calls to xexec(toys.optargs) to avoid freeing and reusing optargs 1876 during option parsing screwing stuff up (such as netcat's exec mode).</p> 1877 1878 <p>The stat command's %a output was padded with leading zeroes, which 1879 didn't match anybody else's behavior and thus made the test suite hiccup 1880 between TEST_HOST and testing toybox. (If you go "TEST_HOST=1 scripts/test.sh 1881 command" it sanity checks the tests against the host implementation.)</p> 1882 1883 <p>Last release, "mkdir sub/sub && chmod 007 sub/sub && rm -rf sub" didn't 1884 delete sub and didn't exit with an error either. Neither was correct, rm 1885 should now be fixed.</p> 1886 1887 <p> 1888 <a name="26-07-2013" /><a href="#26-07-2013"><hr><h2><b>July 26, 2013</b></h2></a> 1889 <p>Georgi Chorbadzhiyski maintains a <a href=https://github.com/gfto/toybox>git 1890 mirror</a> of the repository on github, automatically updated from the 1891 mercurial every 6 hours.

It adds 1902 uuencode and uudecode from Erich Plondke, and enables Luis Morales' "who" by 1903 default. Felix Janda and I cleaned up last year's "stat" submission and 1904 enabled it. Ivo van Poorten added "groups". 1905 Andre Renaud added "lsusb". I implemented "split", "pivot_root", and "mv". 1906 </p> 1907 1908 <p>The "help" command is implemented differently now (lib/help.c) and 1909 each command can now understand --help (including both "toybox --help" 1910 and "toybox --help command" in the multiplexer).</p> 1911 1912 <p>The "pending" directory has several commands (find, xzcat, nbd-client, 1913 logger, expr) which work but are not enabled by default pending further cleanup. 1914 Ifconfig is enabled, but still in pending because it's only 2/3 cleaned up. 1915 (It's an awkward halfway state but I'm not holding up the release for it.)</p> 1916 1917 <p>I'm <a href=cleanup.html>documenting the cleanups</a> to teach 1918 more people to do it, but the writeups aren't caught up yet. The 1919 <a href=roadmap.html>roadmap</a> also got updated a bit with further analysis 1920 of other projects, and the README and about pages got updated.</p> 1921 1922 <p>Fixed _another_ "ls -C" segfault when terminal size can't be detected, 1923 condensed the ls help text to fit on one page, implented --color, and taught 1924 -l to print the major, minor numbers when showing block/char devices. 1925 Argument parsing now handles "--" properly (to end option checking), 1926 and the infrastructure can now handle bare --longopts that have no 1927 corresponding short option (both were implemented before but didn't work). 1928 Fixed an old bug in "patch", chmod grew -f, who grew -a. Isaac Dunham 1929 fixed "-" vs "_" handling in modinfo, added a "firmware" output 1930 field, added -b and -k support, and taught it that the ".ko" extension means 1931 to look for the file at the specified path instead of under /lib. Felix Janda 1932 moved file permission display code to lib so ls and 1933 stat could share it. Ashwini Sharma spotted a bug in xabspath when the 1934 last path component exists but we haven't got permissions to open it 1935 (ala readlink -f /dev/sda as a normal user). 1936 </p> 1937 1938 <p>In the build infrastructure, scripts/findglobals.sh finds leaked global 1939 variables. (Leaked means they aren't part of the global union: Other than glibc 1940 debris, toybox should define "this", "toy_list", "toybuf", and "toys", and 1941 that's it; the rest add memory footprint to every command for the benefit of 1942 just one command; use GLOBALS() to stick 'em in the union.) Static linking 1943 against libraries other than the host's libc now applies to feature probes 1944 for unshare and such. Neuter stupid internationalization support that makes 1945 various host "sort" commands put things in an order other than alphabetical 1946 (breaking the multiplexer's binary search on command names). 1947 1948 <p>You should now be able to build from a source control snapshot on a build 1949 system that hasn't got python: if you disable CONFIG_TOYBOX_HELP. (The 1950 release tarballs ship generated/help.h, but it's not in source control. 1951 Eventually I should rewrite that python script in C.)</p> 1952 </p> 1953 1954 <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 1955 BSD" <a href=license.html>license</a> got slightly simplified so the first 1956 paragraph now says:</p> 1957 1958 <blockquote><p>Permission to use, copy, modify, and/or distribute this 1959 software for any purpose with or without fee is hereby granted.</p></blockquote> 1960 1961 <p>It used to continue "provided that the above copyright notice and this 1962 permission notice appear in all copies", but A) what's the point?

There 2036 are now exactly 100 commands in defconfig (of a little over 220 on the 2037 <a href=roadmap.html>todo list</a>).</p> 2038 2039 <p>Elie De Brauwer added the rev command, cleaned up tac, implemented the -s 2040 and -f flags for seq, added -v and -i to killall (and fixed killall not to 2041 kill itself before finishing its pid list), and added to the test suite. 2042 Felix Janda added -m to mkdir, pwd -L and -P, and more test suite entries.</p> 2043 2044 <p>Rob Landley added the losetup command, and fixed the existing ls, cp, and 2045 readlink commands. The segfault in ls 2046 happened when it couldn't determine the screen size (last release changed the 2047 default to -C and a screen size of 0 made column view unhappy), and cp got an 2048 extensive rewrite bringing it up to date with the dirtree changes and fixing 2049 a number of things it never did right in the first place. The xabspath() 2050 code in the library now handles a symlink after ".." properly (and the test 2051 suite checks for it).</p> 2052 2053 <p>Infrastructure-wise the code is better about automatically setting the 2054 error return code properly. Now error_msg() sets the exit code to 1 if it's 2055 still defaulting to 0, and the global exit path does a fflush(NULL) with error 2056 bit check rather than trying to be quite so granular about flushing. (That 2057 means if we use printf() instead of xprintf() it still exits with the right 2058 error code, it just doesn't end the program early on an output error.) 2059 Minor bugfix so TOYBOX_DEBUG 2060 doesn't always warn about the lack of suid bit when toybox is built with 2061 at least one STAYROOT command. Bugfix for the option [grouping] logic 2062 (and then further fixes to the error reporting pointed out by Ashwini Sharma). 2063 dirtree_handle_callback() now has a prefix like the rest of the dirtree 2064 functions. A lot of stuff doing manual path handling was switched to using 2065 libc basename() (including, embarassingly, the basename command), which means 2066 it now correctly detects "/trailing/slash/" which the previous code didn't.</p> 2067 2068 <p>Also, last release included some accidentally checked in debug code that 2069 disabled compiler optimization, so the binary size bloated a bit. It's back 2070 to -Os by default now.</p> 2071 2072 <a name="15-12-2012" /><a href="#15-12-2012"><hr><h2><b>December 15, 2012</b></h2></a> 2073 <blockquote><p>"The major difference between a thing that might go wrong and a 2074 thing that cannot possibly go wrong is that when a thing that cannot possibly 2075 go wrong goes wrong it usually turns out to be impossible to get at or repair." 2076 </p><p>- The Hitchhiker's Guide to the Galaxy.</p></blockquote> 2077 2078 <p><a href=downloads/toybox-0.4.2.tar.bz2>Toybox 0.4.2</a> is based on 2079 <a href=http://landley.net/hg/toybox/shortlog/749>commit 749</a> and is 2080 just a resync. Linux 3.7 came out, meaning it's time to do an Aboriginal 2081 Linux release, and that should use a stable version of toybox. So here's 2082 a new stable version.</p> 2083 2084 <p>The new commands are cut (from Jason Kyungwan Han), touch 2085 (from Choubey Ji), expand (from Jonathan Clairembault, and he fixed a 2086 bug in login), and rm (from Rob Landley). Felix Janda added UTF-8 2087 support infrastructure (for non-ascii character sets) with a config option. 2088 Elie De Brauwer added tests for cat and sha1sum, and -so options to pidof. 2089 The "ls" command defaults to -C (column view) now, and "readlink" now supports 2090 -fenq.</p> 2091 2092 <p>Portability work: toybox should now build against the musl C library, 2093 and against older glibc versions (circa 2008, much before that and kernel 2094 features we depend on start to drop out).</p> 2095 2096 <p>The whole codebase got reindented from "one tab" to "two spaces" per 2097 level. The option parsing logic now understands [groups] of commands (when more 2098 than one in a group is selected it can switch the others off, or error out, 2099 or other things). The error_exit() infrastructure can now longjmp back to an 2100 earlier point instead of exiting. Each toys/* directory now has a README, 2101 the first line of which is the fancy name menuconfig uses for the directory 2102 (so no more hardwired directory list in scripts/genconfig.sh).</p> 2103 2104 <p>Fixed a filehandle leak in getmountlist(). 2105 Pass parent pointer to dirtree_add_node() so it can give error messages with 2106 full path. The yesno() function now always reads from stdin and writes to 2107 stderr (we can retry tty checking complexity once we've got commands needing 2108 it).</p> 2109 2110 <p>The open group broke their website so the 2111 <a href=http://opengroup.org/onlinepubs/9699919799>old links</a> to POSIX 2008 2112 now <a href=http://pubs.opengroup.org/onlinepubs/9699919799>need to start with 2113 pubs</a>. Some of the links in the tree have been updated, others haven't while 2114 I wait to see if their webmaster notices and fixes it.</p> 2115 2116 <p>(I note that the current rm implementation is not technically posix compliant 2117 because the standard requires infinite recursion depth and the current 2118 implementation uses one filehandle per level. I can add a config option 2119 to do it Posix's way, which is more brittle and needs extra security checks, 2120 but am waiting for somebody to complain first. The default "ulimit -n" is 1024 2121 filehandles, so drilling down over 1000 nested subdirectories).</p> 2122 2123 <a name="13-11-2012" /><a href="#13-11-2012"><hr><h2><b>November 13, 2012</b></h2></a> 2124 <blockquote><p>"Rule Six: The winning team shall be the first team that wins." 2125 - The Hitchhiker's Guide to the Galaxy.</p></blockquote> 2126 2127 <p><a href=downloads/toybox-0.4.1.tar.bz2>Toybox 0.4.1</a> is based on 2128 <a href=http://landley.net/hg/toybox/shortlog/691>commit 691</a>.</p> 2129 2130 <p>Elie De Brauwer contributed usleep, Ashwini Kumar contributed du, and 2131 Kyungwan Han contributed vconfig. Other new commands include switch_root and 2132 md5sum, and the remaining shell wrappers are now proper commands (dos2unix, 2133 unix2dos).</p> 2134 2135 <p>The patch command now supports -l, and gethostname is now enabled by 2136 default. The df command follows symlinks to get the actual device name. 2137 Felix Janda added -m support to wc (for utf8).</p> 2138 2139 <p>On the infrastructure side, the commands have now been grouped into 2140 "posix", "lsb", and "other" subdirectories (for things required by Posix-2008, 2141 the Linux Standard Base 4.1, and commands in neither). This affects menuconfig 2142 and the actual source layout (toys/cp.c is now toys/posix/cp.c, and so on). 2143 An android directory is planned (see the updated 2144 <a href=roadmap.html#android>android roadmap analysis</a>).</p> 2145 2146 <p>The FLAG_ macros for command option parsing and TT alias for the command's 2147 global block are now automatically generated, commands should 2148 #define FOR_commandname before #including <toys.h> to get the macros for that 2149 command.</p> 2150 2151 <p>An upgrade to the build infrastructure now allows commands with _ and - 2152 in them, such as switch_root.</p> 2153 2154 <p>Bugfixes: Avery Pennarun spotted a case where ls showed uid twice instead of 2155 uid and gid, and that nice was using the wrong range of numbers. 2156 The ls command also recursed inappropriately last time (not quite 2157 properly converted for the dirtree changes last release), and now it's 2158 fixed. Roy Tam pointed out a glitch in sh, and fixed df's percentage 2159 calculation to match the POSIX spec. The kernel build didn't like our mktemp 2160 and it does now. The wc command wasn't quite posix compliant (trailing spaces 2161 break stuff). The ls command recursed inappropriately last time (not quite 2162 properly converted for the dirtree changes last release), and now it's 2163 fixed. The catv command wasn't displaying byte 255 correctly. Some lib 2164 fixes (thinko in xpidfile). Fixed uname -m when running a 32 bit x86 binary 2165 on an x86-64 host (it lies and says the system is i686, i586, or i486 depending 2166 on what the toolchain that built the binary supported. This makes builds in 2167 a 32 bit chroot on a 64 bit kernel break less.) The df command was checking 2168 partitions in the wrong order (displaying undermounts instead of overmounts: 2169 this used to work but some library code changed out from under it and it 2170 wasn't updated to match until now). Felix Janda filled out the test suite 2171 some more. The patch file creation logic got tweaked several times to 2172 successfully apply more patches. Support for older (pre 2.10) glibc 2173 versions was added to portability.h.</p> 2174 2175 <p>Miscelaneous cleanups all around (mknod, sha1sum, logname), including a 2176 rewrite of taskset to be less dependent on libc getting the headers right.
