| 16 | |
| 17 | <p><a href=downloads/toybox-0.5.0.tar.bz2>Toybox 0.5.0</a> |
| 18 | (<a href=/hg/toybox/shortlog/1512>commit 1512</a>) is out.</p> |
| 19 | |
| 20 | <h3>New commands</h3> |
| 21 | |
| 22 | <p>The new commands are find, install, factor, and mount. Promoted commands |
| 23 | (cleaned up and moved out of "pending") are lspci, inotifyd, and blockdev.</p> |
| 24 | |
| 25 | <p>cp now implements -HL and -F to force delete of pending files, cpio now |
| 26 | ignores -m and implements -p, ls -C now has utf8 support (using wcwidth |
| 27 | instead of strlen), and umount got a number of upgrades involving |
| 28 | looking things up in /proc/mounts. Other minor cleanups happend to |
| 29 | cut, touch, free, and id.</p> |
| 30 | |
| 31 | <p>In pending: Bradley Controy submitted mix (adjusts OSS sound volume). Ashwini |
| 32 | Sharma submitted diff, userdel, blockdev, ipcs, and crond, upgraded |
| 33 | fdisk, fsck, and ftpget, and ran a static analyzer on a lot of other code. |
| 34 | Partial cleanup was done to useradd, userdel, groupadd, and groupdel.</p> |
| 35 | |
| 36 | <h3>Build infrastructure</h3> |
| 37 | |
| 38 | <p><b>Parallel builds</b></p> |
| 39 | |
| 40 | <p>The build now takes advantage of SMP, autodetecting the number of |
| 41 | processors. (Export the environment variable CPUS to pick a specific number.) |
| 42 | Other build changes: split out $LDOPTIMIZE because old compilers complain |
| 43 | about linker options passed with -c, and the entire "generated" directory now |
| 44 | gets deleted by clean (the README that was in there got merged into code.html).</p> |
| 45 | |
| 46 | <p><b>Standalone builds</b></p> |
| 47 | |
| 48 | <p>The standalone build infrastructure (scripts/single.sh) got upgraded to |
| 49 | build more commands as standalone executables. In make.sh the source file |
| 50 | selection uses a regex to find the source files with the NEWTOY/OLDTOY macro |
| 51 | for the command. It enables each command's |
| 52 | sub-options (so CP has CP_MORE), enables I18N and FLOAT support to build |
| 53 | full-featured commands, and includes --help text (at least when |
| 54 | the command doesn't use another command's help). The OLDTOY() macro |
| 55 | now produces (redundant) function prototypes so you can build an OLDTOY |
| 56 | without the NEWTOY</p> |
| 57 | |
| 58 | <p>It doesn't quite have complete coverage yet, the defconfig entries that |
| 59 | aren't building standalone yet are:</p> |
| 60 | |
| 61 | <blockquote><p>chown, egrep, fgrep, fstype, halt, mv, nc, poweroff, unix2dos, |
| 62 | whoami</p></blockquote> |
| 63 | |
| 64 | <p>The main reason for standalone build failures is NEWTOY() or OLDTOY() |
| 65 | entries that don't have their own config symbol. Another problem is entries |
| 66 | that depend on another entry in kconfig, usually because common infrastructure |
| 67 | is using one command's flags (which the other commands copy): if that command |
| 68 | is disabled, the FLAG macros become 0 so dead code elimination can remove the |
| 69 | code. It's <a href=http://landley.net/hg/toybox/rev/1503>possible |
| 70 | to untangle</a> this, but a bit awkward. (It boils down to conflicting |
| 71 | design goals in the two contexts.)</p> |
| 72 | |
| 73 | <p>Standalone builds are used by the test suite when testing individual |
| 74 | commands. |
| 75 | |
| 76 | <p><b>Snapshot builds</b></p> |
| 77 | |
| 78 | <p>A new addition to the "generated" directory is generated/build.sh |
| 79 | containing a single compiler command line to build toybox in its current |
| 80 | configuration. Combined with the generated/*.{h,sh} files from an |
| 81 | exisiting build, this may let you build on a new system that hasn't quite |
| 82 | got enough OS bits working to run a full configureand make.</p> |
| 83 | |
| 84 | <h3>Internals</h3> |
| 85 | |
| 86 | <p>Library code: xcreate/xopen now O_CLOEXEC by default to avoid leaking |
| 87 | filehandles to child processes. DIRTREE_COMEAGAIN's second callback is now |
| 88 | done with the directory filehandle still open (new dir->again variable added |
| 89 | to distinguish first from second callback, and requesting DIRTREE_RECURSE now |
| 90 | requires passing in the specific macro value, not just a true/false). |
| 91 | Use daemon() out of libc instead of hand-rolled daemonize() in various |
| 92 | pending commands. string_to_mode() now passes through type bits so you can |
| 93 | use it to more easily modify a file's existing mode. |
| 94 | Split xpopen() into xpopen_both(), xopen(), and xrun() depending on whether |
| 95 | we want to redirect both, one, or neither of stdin/stdout.</p> |
| 96 | |
| 97 | <p>Bugfixes: Better error message when TOYBOX_SUID option can't drop priviliges |
| 98 | (which happens when you suid something _other_ than root). |
| 99 | The old pending version of nbd_client.c wasn't deleted when the |
| 100 | command was promoted (and the build would break if both were enabled), |
| 101 | toy_exec() sometimes needs to re-exec from $PATH rather than recurse |
| 102 | internally (to gain dropped root permissions or limit stack depth), |
| 103 | always call setlocale() when I18N is enabled to switch it back _off_ when |
| 104 | we run commands that expect sscanf("%n") to return bytes, |
| 105 | dirtree() had a memory leak in an error path, patch.c had some bugs in |
| 106 | error paths (didn't report problem clearly). Ashwini Sharma spotted an |
| 107 | option parsing bug where [-abc] would forget _all_ command line arguments |
| 108 | saved in the GLOBALS() block (not just the ones for options being switched |
| 109 | off), plus various minor fixes to nbd_client and cpio. |
| 110 | Lukasz Szpakowski fixed rm -f on a broken symlink (failed), and killall |
| 111 | with no arguments (segfaulted).</p> |
| 112 | |
| 113 | <p><b>Portability</b></p> |
| 114 | |
| 115 | <p>A somewhat fiddly fix to rm -rf (which needs to chmod directories to u+rwx |
| 116 | to descend into them) which hit a musl bug in faccessat() which the musl |
| 117 | maintainer refuses to fix. (He literally wants the man page changed |
| 118 | instead, despite other libcs working.) Added an #ifdef __MUSL__ section |
| 119 | to portability.h with a workaround, you may need CFLAGS=-D__MUSL__ in your |
| 120 | build if your musl build's features.h doesn't #define that. (I may do |
| 121 | a different workaround in future, but sometimes you've just got to make |
| 122 | it work so you can ship. Also, toybox grep with multiple patterns |
| 123 | requires <a href=http://landley.net/hg/aboriginal/rev/1692>a patch |
| 124 | to musl's regex engine</a>, which applies to 1.1.4 but not to the current |
| 125 | musl source control.)</p> |
| 126 | |
| 127 | <p>More portability.h fixes for uClibc too. (I don't expect that to ever have |
| 128 | another release, so locally patching around posix-2008 violations is silly).</p> |
| 129 | |
| 130 | <p><b>Change to username filtering</b></p> |
| 131 | |
| 132 | <p>Posix recommends the username creation logic filter usernames to a small |
| 133 | allowed set of characters (which even Red Hat breaks by explicitly allowing |
| 134 | "$" at the end), but this prevents UTF-8 usernames. Posix' stated logic |
| 135 | is to allow filesystems to create the user's home directory, but Linux |
| 136 | filesystems can accept any character but NUL and "/". The only characters |
| 137 | we actually _need_ to filter out are ":" (field separator in passwd), |
| 138 | newline (line separator in passwd), and "/" (directory separator in |
| 139 | filesystem).</p> |
| 140 | |
| 141 | <h3>Documentation</h3> |
| 142 | |
| 143 | <p>Web pages updated: cleanup.html documents more cleanup, code.html |
| 144 | documents more code, and about.html now capitalizes "toybox" consistently |
| 145 | (it's just a word, capitalize at start of sentence).</p> |
| 146 | |
| 147 | <p>The pending/README file now lists commands that needed review/cleanup |
| 148 | before the pending directory was added.</p> |
| 149 | |
| 150 | <h3>Test Suite</h3> |
| 151 | |
| 152 | <p>Moved out of scripts/test into top level "tests" directory, and the |
| 153 | testing.sh script is now in scripts rather than mixed into the *.test files.</p> |
| 154 | |
| 155 | <p>Johan Bergström requested VERBOSE=fail to make tests (telling it to |
| 156 | stop at the first failure), and spotted a build bug where using gnu |
| 157 | sort on the host broke in non-C locales.</p> |
| 158 | |
| 159 | <p>Divya Kothari submitted tests for chmod, link, tar, bzcat, xzcat, zcat, |
| 160 | and hostname. (And more, but that's all that's merged so far.)</p> |
| 161 | |

| 170 | <p><a href=downloads/toybox-0.4.9.tar.bz2>Toybox 0.4.9</a> (<a href=/hg/toybox/shortlog/1385>commit 1385</a>) is out.</p> |
| 171 | |
| 172 | <p><b>New commands</b> added to pending include: |
| 173 | lsattr, chattr, inotifyd, rfkill, sulogin, strings, makedevs, |
| 174 | killall5, and tar from Ashwini Sharma, arp from Kyungwan Han, |
| 175 | sysctl by Bilal Qureshi, partprobe from Bertold Van den Bergh, |
| 176 | host from Rich felker, and I did nbd-client and the first 2/3 of mount.</p> |
| 177 | |
| 178 | <p>Finished cleanups (commands promoted out of pending): |
| 179 | sysctl, rfkill, strings, mkpasswd, makedevs, partprobe, killall5, |
| 180 | fallocate, and nbd-client.</p> |
| 181 | |
| 182 | <p>(Along the way partial cleanups got made to: last, fold, lspci, ps, |
| 183 | bootchartd, init, fsck, telnetd, telnet, vconfig, toysh, iconv, useradd, |
| 184 | login, host, openvt, deallocvt, getty, tftpd, and modprobe. But there's |
| 185 | still more to do on all of those.)</p> |
| 186 | |
| 187 | <p>This time around the <a href=bin>static binaries</a> are linked against |
| 188 | musl instead of uClibc. (That's why there's no sparc version, musl doesn't |
| 189 | support that target yet.)</p> |
| 190 | |
| 191 | <p><b>Documentation:</b></p> |
| 192 | |
| 193 | <p>The help text parser expects lower case "usage:" lines with |
| 194 | a blank line after them, so go through and regularize those. Expand the |
| 195 | "coding style" section in the docs and move it to design.html. (Not a show |
| 196 | stopper for incoming |
| 197 | contributions, just an explanation of some of the things I'll do to them |
| 198 | during cleanup.) The help text for the "toybox" command now includes |
| 199 | the shell script snippet to install symlinks to the toybox binary.</p> |
| 200 | |
| 201 | <p>The <a href=cleanup.html>cleanup page</a> now has descriptions for the |
| 202 | full ifconfig cleanup series, among others.</p> |
| 203 | |
| 204 | <p>The new toys/examples directory contains hello.c and skeleton.c. The first is |
| 205 | a simple hello world program in toybox style, the second is a much more |
| 206 | elaborate example program using showing how to use the command line option |
| 207 | parsing and how to provide multiple commands in the same C file.</p> |
| 208 | |
| 209 | <p><b>Fixes</b>:</p> |
| 210 | |
| 211 | <p>Fix od bug reported by Samuel Holland ("od -v -b" was appending the default |
| 212 | output type even though an output type was specified). Ashwini Sharma reported |
| 213 | bugs where readfile() was incorrectly freeing its buffer, and where toy_init() |
| 214 | was zeroing the wrong data because the field it was using to measure (rebound) |
| 215 | had moved (when I moved it back I added a comment why the field needs to be |
| 216 | there), fixed a segfault in the dhcp client, and made a 0 length read at |
| 217 | the start of password entry count as EOF. Make the "we are not root" test |
| 218 | in the init code show the help text. Posix implies that fflush() can return |
| 219 | success even when the stream's error bit is set, so call both fflush() and |
| 220 | ferror() from xprintf().</p> |
| 221 | |
| 222 | <p>Isaac Dunham pointed out that bloatcheck couldn't deal with diff |
| 223 | implementations that only implement "unified diff" format, and that some |
| 224 | diff implementations can't handle nonseekable input (I.E. reading from |
| 225 | a pipe). Bugfix so "help -a" works again. Option parsing on nohup now stops |
| 226 | at first nonoption argument. Fix segfault in "which" if PATH wasn't set, |
| 227 | which was actually a bug in lib function find_in_path(). Made rm -rf of |
| 228 | chmod 000 directories actually remove them.</p> |
| 229 | |
| 230 | <p>The build now passes the same $CFLAGS to the library probe as the final |
| 231 | build, because arch linux is so broken it provides different sets of |
| 232 | libraries for static and dynamic linking.</p> |
| 233 | |
| 234 | <p>It turns out sprintf("%.123s", str) is counting characters, not bytes, |
| 235 | so globally enabling locale support opens stack smashing vulnerabilities. |
| 236 | So there's a new TOYFLAGS_LOCALE you set in toyflags when you want the |
| 237 | setup code to setlocale().</p> |
| 238 | |
| 239 | <p><b>Upgrades:</b></p> |
| 240 | |
| 241 | <p>Isaac Dunham extended cpio to archive unreadable empty files, and I taught it |
| 242 | to set uid/gid and timestamp when extracting archives. Isaac also |
| 243 | added tests for cpio, link, and du, added lspci -i, made the pci database |
| 244 | parsing skip # comment lines, merged logname and whoami into id.</p> |
| 245 | |
| 246 | <p>Daniel Verkamp sped up md5sum about 30% with some loop unrolling, making |
| 247 | it actually smaller in the process. I added -b flags to md5sum and sha1sum |
| 248 | for "brief" output that's just the hash with no filename. (I'm aware other |
| 249 | implementations use that for MSDOS "binary" mode, and don't care.)</p> |
| 250 | |
| 251 | <p>When building standalone commands (scripts/singleconfig.sh commandname), |
| 252 | the build now switches on all the sub-options of the command so we get |
| 253 | a standalone version with all the bells and whistles enabled.</p> |
| 254 | |
| 255 | <p>Add -ds flags to date and document +FORMAT escapes. Add the shell NOP |
| 256 | command ":" as an alias for true (for toysh).</p> |
| 257 | |
| 258 | <p>Add uClibc probe for iconv() and fallocate. (The fact it didn't always |
| 259 | build against uClibc is why fallocate wasn't enabled in defconfig before.)</p> |
| 260 | |
| 261 | <p>The umount command now does an losetup -d on the device by default, so |
| 262 | we don't leak loopback devices. Bugfix to losetup so "losetup /dev/loop0 |
| 263 | filename" actually works again.</p> |
| 264 | |
| 265 | <p>Divya Kothari sent in test suite entries for ls, ln, rm, mv, printf, dd, |
| 266 | and renice. Then a second round for lsattr/chattr, mount, chmod, pgrep/pkill, |
| 267 | groupadd, groupdel, and useradd. Several of these uncovered bugs, still |
| 268 | working to fix them.</p> |
| 269 | |
| 270 | <p>There are now free() functions for the predefined llist types and a |
| 271 | dlist_terminate() function to break doubly linked lists. The new |
| 272 | generic_signal() handler either sets "toys.signal" or writes a byte |
| 273 | to toys.signalfd with the signal number if signalfd isn't -1 (which it's |
| 274 | initialized to in toy_init).</p> |
| 275 | |
| 276 | <p>The option parsing logic can now detect when a double fits in a long and |
| 277 | use the more precise type for floating point arguments (the FLOAT macro |
| 278 | contains the type used). The human_readable() function now just outputs |
| 279 | decimal kilo/mega/gigabytes (so when du -u says 5.0G it means 5.0 billion |
| 280 | bytes). The build infrastructure now notices duplicate commands (so if you |
| 281 | cp toys/pending/command.c toys/other/command.c and forget to delete the |
| 282 | first one, the build break is now more informative).</p> |
| 283 | |

| 289 | turn it off. - The Hitchhiker's Guide to the Galaxy.</p></blockquote> |
| 290 | |
| 291 | <p><a href=downloads/toybox-0.4.8.tar.bz2>Toybox 0.4.8</a> is based on |
| 292 | <a href=http://landley.net/hg/toybox/shortlog/1262>commit 1262</a>. And |
| 293 | about time too.</p> |
| 294 | |
| 295 | <p>The big news is that the build no longer needs python to generate help.h, |
| 296 | that's now done in C. The help text generation is also collating help text |
| 297 | from multiple options, merging command line option blocks and usage: lines. |
| 298 | There's even a new <a href=help.html>help web page</a>.</p> |
| 299 | |
| 300 | <p><b>New commands:</b> Ifconfig, cpio, and su were cleaned up the rest of the |
| 301 | way and promoted out of pending. That saga is mostly explained on the |
| 302 | <a href=cleanup.html>cleanup page</a>. Vivek Bhagat's freeramdisk, |
| 303 | Isaac Dunham's fsfreeze, and Felix Janda's iconv are also new.</p> |
| 304 | |
| 305 | <p><b>In pending:</b> |
| 306 | Ashwini Sharma's team submitted tcpsvd, udpsvd, telnet, telnetd, last, more, |
| 307 | groupdel/delgroup, arping, brctl, ftpget, ftpput, printf, reset, and added |
| 308 | ipv6 support to traceroute. Kyungwan Han's team submitted modprobe and getty. |
| 309 | Vivek Bhagat submitted openvt and deacllocvt. Samuel Holland submitted fold. |
| 310 | I wrote a new inflate (zip/zlib/gzip decompression) implementation in |
| 311 | compress.c, and still need to do a corresponding deflate (compression-side) |
| 312 | and plug them into gzip and zip and so on. (Right now it does zcat.)</p> |
| 313 | |
| 314 | <p>Several commands (vmstat, login, du, vconfig, mountpoint, free, chroot, |
| 315 | cut, touch, modinfo, expand) predate the "pending" directory, and are thus |
| 316 | in other directories but still need cleanup. Of these, vmstat got some |
| 317 | work this time (which would be much easier other vmstat implementations |
| 318 | documented what their output actually meant).</p> |
| 319 | |
| 320 | <p><b>Upgrades:</b> Ifconfig grew /prefix netmask support (ala 1.2.3.4/24). Grep now has -zZ to |
| 321 | handle null terminated data, cksum grew -H for hex output. Upgraded od so the |
| 322 | fields align better when producing multiple output types. Help has -a and -h |
| 323 | options (all commands, html output). |
| 324 | Bugfix to blkid building for a 32 bit target. The date command can actually |
| 325 | set dates now. The O_NOFOLLOW compile time probe didn't work with cross |
| 326 | compiling, so it's back to an #ifdef test in portability.h. Nathan McSween |
| 327 | sent in a bugfix to od and a portability fix in the common library code. |
| 328 | Ashwini Sharma spotted a bug in pidof -o, and added verbose (-v) options |
| 329 | to mkdir and ln, and suggested killall should have an -s option and |
| 330 | allow -l to take zero arguments. Ashwini Sharma and Felix Janda upgraded |
| 331 | tftpd. Fixed dumpleases still using toynet.h after |
| 332 | that was removed. Corrected killall return code and error reporting. |
| 333 | Isacc Dunham fixed bugs all over the tree, did cleanup on a bunch of |
| 334 | pending commands (getty, ftpget, init, openvt, modprobe...), and clarified |
| 335 | find's help text. Tom Sparrow ran three different static analyzers on |
| 336 | the code, which resulted in a few cleanups. The peek()/poke() functions |
| 337 | now use "volatile" to prevent broken compiler "optimizations" to do with |
| 338 | aliasing.</p> |
| 339 | |
| 340 | <p><b>Build stuff:</b> Each FOR_xxxx macro now has a complementary CLEANUP_xxxx macro, so you |
| 341 | can put multiple commands with different command line options in the same |
| 342 | .c file, so they can share infrastructure outside of lib. (This let the |
| 343 | bunzip logic move out of lib into bzcat.c.) See XXX for example. |
| 344 | i |
| 345 | <p>The headers #included in toys.h are now grouped by standard, and headers |
| 346 | not listed in Posix or LSB were moved to portability.h. The old xregcomp.h |
| 347 | was folded into lib.h because it's posix (and supporting oddball uClibc |
| 348 | configurations isn't as important as it once was).</p> |
| 349 | |
| 350 | <p>Regression tested against Ubuntu 8.04 to fix up bit-rot in defconfig |
| 351 | build on older systems. (We depend on Posix-2008, but not necessarily |
| 352 | the absolute latest build environment.)</p> |
| 353 | |
| 354 | <p><b>In lib</b>: lib/xwrap.c added xgetpwnam(), xchroot(), and lib/lib.c now has names_to_pid(). |
| 355 | xsetuid() was replaced with xsetuser() which takes a struct passwd |
| 356 | and sets both gid and uid, mkpathat() got factored out into a library command, |
| 357 | get_int_value() became atolx_range(), and |
| 358 | xmsprintf() is now just xmprintf(). The bunzip2 logic moved from lib into |
| 359 | bzcat.c.</p> |
| 360 | |
| 361 | <p><b>Documentation</b>: new <a href=help.html>help page</a> with the |
| 362 | help text for all the defconfig commands, using the new help -ah output. |
| 363 | The <a href=code.html>source code walkthrough</a> now says more about |
| 364 | #including header files, and how the generated/* directory works. The |
| 365 | <a href=design.html>design page</a> has some new paragraphs about trading |
| 366 | of different kinds of simplicity, and why comments aren't a substitute for |
| 367 | good code. The README no longer trails off into obvious unfinished confusion |
| 368 | at the end. Each page on the website should now have its own title.</p> |

| 376 | |
| 377 | <p>New commands: Brad Conroy submitted blkid. Elie De Brauwer submitted |
| 378 | reboot, halt, and poweroff. Strake's nl got cleaned up and promoted from |
| 379 | pending to posix. In addition, the existing chvt and vconfig got some |
| 380 | cleanup.</p> |
| 381 | |
| 382 | <p>That said, I haven't nearly kept up with the flood of new commands going |
| 383 | into pending: Ashwini Sharma's team submitted |
| 384 | dd, dumpleases, traceroute, top, useradd, groupadd, mkpasswd, tftpd, and |
| 385 | an fsck wrapper (with no filesystem drivers yet). Isaac Dunham sent in cpio.</p> |
| 386 | |
| 387 | <p>Bugfixes: Jeroen van Rijn added a user count to uptime. Elie De Brauwer |
| 388 | added -e to watch, removed a memory leak, and fixed a terminal size problem. |
| 389 | William Haddon made xargs call its command line once even with blank input |
| 390 | (the standard is vague, but builds expect it), and fixed an off by one bug |
| 391 | where grep didn't malloc enough space with -E (leading to a segfault). |
| 392 | I fixed a glitch in bunzip2 (same one as went into busybox since they're using |
| 393 | the code I wrote), in od to fix -t co, -J, and -c options. Add uname -o as a |
| 394 | synonym for -s. Build fix to never use $CC without prefixing it with |
| 395 | $CROSS_COMPILE (since $HOSTCC could be different). Anca Emanuel spotted |
| 396 | a typo in the web page.</p> |
| 397 | |
| 398 | <p>The compile-time command line option parsing got rewritten (ported from |
| 399 | bash to C), which should speed up builds a bit and allow code controlled by |
| 400 | --longopts to drop out properly when disabled in the configuration. Terminal |
| 401 | querying got refactored. Patch's -x option is now more informative (a |
| 402 | debug thing if you're trying to figure out why a patch didn't apply). |
| 403 | The "toynet.h" file got folded into toys.h since musl supports it and |
| 404 | micromanging uClibc options isn't very interesting anymore. The test suite |
| 405 | now uses scripts/single.sh when testing a single command.</p> |

| 415 | <a href=http://landley.net/hg/toybox/shortlog/1068>commit 1068</a>.</p> |
| 416 | |
| 417 | <p>This release adds |
| 418 | several new commands: Felix Janda wrote paste and fallocate, Kyungwan Han |
| 419 | submitted eject, Strake contributed grep, Ashwini Sharma added pmap (and |
| 420 | a testsuite entry for grep), Lukasz Skalski sent pwdx, Isaac Dunham posted |
| 421 | acpi, and I did timeout and umount.</p> |
| 422 | |
| 423 | <p>The ls command now has a --color=auto option (suggested by Rich Felker). |
| 424 | The multiplexer now has a --help option so you can say "./toybox --help blah" |
| 425 | instead of using the built-in "help" command. (Which is a shell built-in. |
| 426 | Try it on your command line, it's like man for shell builtins. But a certain |
| 427 | other project has conditioned people to expect --help, so...) I forget who |
| 428 | heehooman at gmail is but they pointed out unshare needed PID and UID |
| 429 | namespace support.</p> |
| 430 | |
| 431 | <h3>Pending</h3> |
| 432 | |
| 433 | <p>A lot of new commands in toys/pending, to the point the next release should |
| 434 | probably just focus on cleanup and review of this backlog. We've got klogd, |
| 435 | dhcp, dhcpd, watch, route, and ps from |
| Rob Landley | d277414 | 2013-10-04 14:32:39 -0500 | [diff] [blame] | 436 | Ashwini Sharma (and an fsck wrapper but no fsck.fstype engines yet), |
| Rob Landley | 5cab994 | 2013-09-18 10:50:38 -0500 | [diff] [blame] | 437 | syslogd, pgrep, and pkill from Madhur Verma, netstat by Ranjan Kumar, |
| 438 | test by Felix Janda, lspci by Isaac Dunham, nl, su, and renice by strake (I.E. |
| 439 | M. Farkas-Dyck), and sysvinit by Kyungwan Han.</p> |
| 440 | |
| 441 | <p>Some cleanup work on existing pending commands that aren't |
| 442 | ready to promote yet: I did a few more rounds on ifconfig |
| 443 | and Isaac Dunham's did several cleanups to xzcat, Felix Janda cleaned up |
| 444 | logger and syslogd...</p> |
| 445 | |
| 446 | <p>Also some cleanup work on commands that predate the pending directory, |
| 447 | but weren't quite polished when they went in, most prominently du, |
| 448 | expand, and touch.</p> |
| 449 | |
| 450 | <h3>Infrastructure</h3> |
| 451 | |
| 452 | <p>The new scripts/single.sh builds a standalone command without the |
| 453 | multiplexer, although not all commands can be built that way yet (NEWTOY yes, |
| 454 | OLDTOY no) and the space savings aren't anything to write home about. (If a |
| 455 | command needs the option parsing logic at all, it needs all of it.) If |
| 456 | you're curious, you can do:</p> |
| 457 | |
| 458 | <blockquote><pre> |
| 459 | make defconfig |
| 460 | make |
| 461 | mkdir singles |
| 462 | for i in $(./toybox) |
| 463 | do |
| 464 | echo $i |
| 465 | PREFIX=singles/ scripts/single.sh $i || break |
| 466 | done |
| 467 | </pre> |
| 468 | <p>(And then wait a long time and watch almost half the builds fail.)</p> |
| 469 | </blockquote> |
| 470 | |
| 471 | <p>There is now libbuf analogous to toybuf, another global 4k buffer this |
| 472 | time for use by lib/ code instead of command code.</p> |
| 473 | |
| 474 | <p>The lib directory got split up a bit, lib/pending.c contains functions |
| 475 | not yet used by anything outside of toys/pending/*, and lib/xwrap.c contains |
| 476 | functions that wrap other functions and handle failures (via error_exit). |
| 477 | This leaves lib/lib.c containing actual new functions.</p> |
| 478 | |
| 479 | <p>General improvements and bug fixes to argument parsing. The [-abc] exclude |
| 480 | logic should now clear arguments slots when disabling options. Bare --longopts |
| 481 | should work now and be able to report errors using their name, the new ; |
| 482 | option allows optional arguments to longopts only suppliable with = (I.E. |
| 483 | --color and --color=auto but not --color auto).</p> |
| 484 | |
| 485 | <p>I'm gradually weaning the code off of itoa()/utoa() because sprintf |
| 486 | does this already. In this case "simple" probably means "let libc do it |
| 487 | for us".</p> |
| 488 | |
| 489 | <p>Rewrote for_each_pid_with_name_in() and renamed it to just names_to_pid(). |
| 490 | It shouldn't get confused trying to compare absolute and relative paths quite |
| 491 | so much anymore.</p> |
| 492 | |
| 493 | <p>lib/llist.c grew a new dlist_pop() function for removing a doubly |
| 494 | linked list entry while maintaining a circular list; tail and patch are |
| 495 | using it now.</p> |
| 496 | |
| 497 | <p>The musl guys suggested a new optimization flag |
| 498 | (-fno-asynchronous-unwind-tables) |
| 499 | that shaves about 10% off the binary size by removing a C++ism that crept |
| 500 | into gcc's idea of C. While I don't normally try to micromanage the compiler, |
| 501 | "-fstop-being-stupid" is a thing you have to hit gcc with from time to time.</p> |
| 502 | |
| 503 | <h3>Bugfixes</h3> |
| 504 | |
| 505 | <p>Felix Janda and I did a largeish rewrite of tail to |
| 506 | finally make it work right (we think). Still need to implement tail -f |
| 507 | someday (the tricky bit is making -f follow multiple files at once). |
| 508 | Felix also reported a bug in xpidfile.</p> |
| 509 | |
| 510 | <p>Juhani Haverinen pointed out that |
| 511 | python 3 doesn't work with config2help.py, so the detection logic looks |
| 512 | for python2 (until I get around to rewriting that in C). Elie De Brauwer |
| 513 | then fixed our first attempt at this, and also fixed uname's help string.</p> |
| 514 | |
| 515 | <p>Ashwini Sharma |
| 516 | pointed out the build was making a FLAG_ macro for " " which broke some |
| 517 | configurations. (That's a control character, not a command line option.)</p> |
| 518 | |
| 519 | <p>Jacek Bukarewicz pointed out a bug in chdir permission handling, and |
| 520 | a way to make env segfault. Both should be fixed now.</p> |
| 521 | |
| 522 | <p>The new function xexec_optargs() |
| 523 | replaces calls to xexec(toys.optargs) to avoid freeing and reusing optargs |
| 524 | during option parsing screwing stuff up (such as netcat's exec mode).</p> |
| 525 | |
| 526 | <p>The stat command's %a output was padded with leading zeroes, which |
| 527 | didn't match anybody else's behavior and thus made the test suite hiccup |
| 528 | between TEST_HOST and testing toybox. (If you go "TEST_HOST=1 scripts/test.sh |
| 529 | command" it sanity checks the tests against the host implementation.)</p> |
| 530 | |
| 531 | <p>Last release, "mkdir sub/sub && chmod 007 sub/sub && rm -rf sub" didn't |
| 532 | delete sub and didn't exit with an error either. Neither was correct, rm |
| 533 | should now be fixed.</p> |

| 547 | |
| 548 | <p><a href=downloads/toybox-0.4.5.tar.bz2>Toybox 0.4.5</a> is based on |
| 549 | <a href=http://landley.net/hg/toybox/shortlog/941>commit 941</a>. It adds |
| 550 | uuencode and uudecode from Erich Plondke, and enables Luis Morales' "who" by |
| 551 | default. Felix Janda and I cleaned up last year's "stat" submission and |
| 552 | enabled it. Ivo van Poorten added "groups". |
| 553 | Andre Renaud added "lsusb". I implemented "split", "pivot_root", and "mv". |
| 554 | </p> |
| 555 | |
| 556 | <p>The "help" command is implemented differently now (lib/help.c) and |
| 557 | each command can now understand --help (including both "toybox --help" |
| 558 | and "toybox --help command" in the multiplexer).</p> |
| 559 | |
| 560 | <p>The "pending" directory has several commands (find, xzcat, nbd-client, |
| 561 | logger, expr) which work but are not enabled by default pending further cleanup. |
| 562 | Ifconfig is enabled, but still in pending because it's only 2/3 cleaned up. |
| 563 | (It's an awkward halfway state but I'm not holding up the release for it.)</p> |
| 564 | |
| 565 | <p>I'm <a href=cleanup.html>documenting the cleanups</a> to teach |
| 566 | more people to do it, but the writeups aren't caught up yet. The |
| 567 | <a href=roadmap.html>roadmap</a> also got updated a bit with further analysis |
| 568 | of other projects, and the README and about pages got updated.</p> |
| 569 | |
| 570 | <p>Fixed _another_ "ls -C" segfault when terminal size can't be detected, |
| 571 | condensed the ls help text to fit on one page, implented --color, and taught |
| 572 | -l to print the major, minor numbers when showing block/char devices. |
| 573 | Argument parsing now handles "--" properly (to end option checking), |
| 574 | and the infrastructure can now handle bare --longopts that have no |
| 575 | corresponding short option (both were implemented before but didn't work). |
| 576 | Fixed an old bug in "patch", chmod grew -f, who grew -a. Isaac Dunham |
| 577 | fixed "-" vs "_" handling in modinfo, added a "firmware" output |
| 578 | field, added -b and -k support, and taught it that the ".ko" extension means |
| 579 | to look for the file at the specified path instead of under /lib. Felix Janda |
| 580 | moved file permission display code to lib so ls and |
| 581 | stat could share it. Ashwini Sharma spotted a bug in xabspath when the |
| 582 | last path component exists but we haven't got permissions to open it |
| 583 | (ala readlink -f /dev/sda as a normal user). |
| 584 | </p> |
| 585 | |
| 586 | <p>In the build infrastructure, scripts/findglobals.sh finds leaked global |
| 587 | variables. (Leaked means they aren't part of the global union: Other than glibc |
| 588 | debris, toybox should define "this", "toy_list", "toybuf", and "toys", and |
| 589 | that's it; the rest add memory footprint to every command for the benefit of |
| 590 | just one command; use GLOBALS() to stick 'em in the union.) Static linking |
| 591 | against libraries other than the host's libc now applies to feature probes |
| 592 | for unshare and such. Neuter stupid internationalization support that makes |
| 593 | various host "sort" commands put things in an order other than alphabetical |
| 594 | (breaking the multiplexer's binary search on command names). |
| 595 | |
| 596 | <p>You should now be able to build from a source control snapshot on a build |
| 597 | system that hasn't got python: if you disable CONFIG_TOYBOX_HELP. (The |
| 598 | release tarballs ship generated/help.h, but it's not in source control. |
| 599 | Eventually I should rewrite that python script in C.)</p> |

| 602 | <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 |
| 603 | BSD" <a href=license.html>license</a> got slightly simplified so the first |

| 609 | <p>It used to continue "provided that the above copyright notice and this |
| 610 | permission notice appear in all copies", but A) what's the point? B) does "all |
| 611 | copies" mean binaries, or just source code, or what? C) lots of projects |
| 612 | that consider BSD and GPL compatible have <a href=https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/crypto/aes_generic.c>files with |

| 664 | <p>The "cp" command now implements the -s symlink option, plus bugfixes |
| 665 | getting various corner cases right as used in actual package builds. |
| 666 | "id -Gn root" should now print root's groups |
| 667 | instead of the current user's. Several build fixes so toybox builds under |
| 668 | Ubuntu 8.04 again (which is about as old a build environment as you |
| 669 | can expect to find posix-2008 features in).</p> |
| 670 | |
| 671 | <p>Unfinished commands have generally been moved to "toys/pending". |
| 672 | Everything else should "default y" to participate in make defconfig. |
| 673 | Several of those pending commands got some basic cleanup so allyesconfig |
| 674 | should at least compile (although defconfig is still what's useful).</p> |
| 675 | |
| 676 | <p>Significant roadmap updates, checking several other multicall binaries |
| 677 | (klibc, sash, sbase, s6...) to see what commands they include.</p> |

| 681 | |
| 682 | <p><a href=downloads/toybox-0.4.3.tar.bz2>Toybox 0.4.3</a> is based on |
| 683 | <a href=http://landley.net/hg/toybox/shortlog/793>commit 793</a>. There |
| 684 | are now exactly 100 commands in defconfig (of a little over 220 on the |
| 685 | <a href=roadmap.html>todo list</a>).</p> |
| 686 | |
| 687 | <p>Elie De Brauwer added the rev command, cleaned up tac, implemented the -s |
| 688 | and -f flags for seq, added -v and -i to killall (and fixed killall not to |
| 689 | kill itself before finishing its pid list), and added to the test suite. |
| 690 | Felix Janda added -m to mkdir, pwd -L and -P, and more test suite entries.</p> |
| 691 | |
| 692 | <p>Rob Landley added the losetup command, and fixed the existing ls, cp, and |
| 693 | readlink commands. The segfault in ls |
| 694 | happened when it couldn't determine the screen size (last release changed the |
| 695 | default to -C and a screen size of 0 made column view unhappy), and cp got an |
| 696 | extensive rewrite bringing it up to date with the dirtree changes and fixing |
| 697 | a number of things it never did right in the first place. The xabspath() |
| 698 | code in the library now handles a symlink after ".." properly (and the test |
| 699 | suite checks for it).</p> |
| 700 | |
| 701 | <p>Infrastructure-wise the code is better about automatically setting the |
| 702 | error return code properly. Now error_msg() sets the exit code to 1 if it's |
| 703 | still defaulting to 0, and the global exit path does a fflush(NULL) with error |
| 704 | bit check rather than trying to be quite so granular about flushing. (That |
| 705 | means if we use printf() instead of xprintf() it still exits with the right |
| 706 | error code, it just doesn't end the program early on an output error.) |
| 707 | Minor bugfix so TOYBOX_DEBUG |
| 708 | doesn't always warn about the lack of suid bit when toybox is built with |
| 709 | at least one STAYROOT command. Bugfix for the option [grouping] logic |
| 710 | (and then further fixes to the error reporting pointed out by Ashwini Sharma). |
| 711 | dirtree_handle_callback() now has a prefix like the rest of the dirtree |
| 712 | functions. A lot of stuff doing manual path handling was switched to using |
| 713 | libc basename() (including, embarassingly, the basename command), which means |
| 714 | it now correctly detects "/trailing/slash/" which the previous code didn't.</p> |
| 715 | |
| 716 | <p>Also, last release included some accidentally checked in debug code that |
| 717 | disabled compiler optimization, so the binary size bloated a bit. It's back |
| 718 | to -Os by default now.</p> |

| 725 | |
| 726 | <p><a href=downloads/toybox-0.4.2.tar.bz2>Toybox 0.4.2</a> is based on |
| 727 | <a href=http://landley.net/hg/toybox/shortlog/749>commit 749</a> and is |
| 728 | just a resync. Linux 3.7 came out, meaning it's time to do an Aboriginal |
| 729 | Linux release, and that should use a stable version of toybox. So here's |
| 730 | a new stable version.</p> |
| 731 | |
| 732 | <p>The new commands are cut (from Jason Kyungwan Han), touch |
| 733 | (from Choubey Ji), expand (from Jonathan Clairembault, and he fixed a |
| 734 | bug in login), and rm (from Rob Landley). Felix Janda added UTF-8 |
| 735 | support infrastructure (for non-ascii character sets) with a config option. |
| 736 | Elie De Brauwer added tests for cat and sha1sum, and -so options to pidof. |
| 737 | The "ls" command defaults to -C (column view) now, and "readlink" now supports |
| 738 | -fenq.</p> |
| 739 | |
| 740 | <p>Portability work: toybox should now build against the musl C library, |
| 741 | and against older glibc versions (circa 2008, much before that and kernel |
| 742 | features we depend on start to drop out).</p> |
| 743 | |
| 744 | <p>The whole codebase got reindented from "one tab" to "two spaces" per |
| 745 | level. The option parsing logic now understands [groups] of commands (when more |
| 746 | than one in a group is selected it can switch the others off, or error out, |
| 747 | or other things). The error_exit() infrastructure can now longjmp back to an |
| 748 | earlier point instead of exiting. Each toys/* directory now has a README, |
| 749 | the first line of which is the fancy name menuconfig uses for the directory |
| 750 | (so no more hardwired directory list in scripts/genconfig.sh).</p> |
| 751 | |
| 752 | <p>Fixed a filehandle leak in getmountlist(). |
| 753 | Pass parent pointer to dirtree_add_node() so it can give error messages with |
| 754 | full path. The yesno() function now always reads from stdin and writes to |
| 755 | stderr (we can retry tty checking complexity once we've got commands needing |
| 756 | it).</p> |
| 757 | |
| 758 | <p>The open group broke their website so the |
| 759 | <a href=http://opengroup.org/onlinepubs/9699919799>old links</a> to POSIX 2008 |
| 760 | now <a href=http://pubs.opengroup.org/onlinepubs/9699919799>need to start with |
| 761 | pubs</a>. Some of the links in the tree have been updated, others haven't while |
| 762 | I wait to see if their webmaster notices and fixes it.</p> |
| 763 | |
| 764 | <p>(I note that the current rm implementation is not technically posix compliant |
| 765 | because the standard requires infinite recursion depth and the current |
| 766 | implementation uses one filehandle per level. I can add a config option |
| 767 | to do it Posix's way, which is more brittle and needs extra security checks, |
| 768 | but am waiting for somebody to complain first. The default "ulimit -n" is 1024 |
| 769 | filehandles, so drilling down over 1000 nested subdirectories).</p> |

| 777 | |
| 778 | <p>Elie De Brauwer contributed usleep, Ashwini Kumar contributed du, and |
| 779 | Kyungwan Han contributed vconfig. Other new commands include switch_root and |
| 780 | md5sum, and the remaining shell wrappers are now proper commands (dos2unix, |
| 781 | unix2dos).</p> |
| 782 | |
| 783 | <p>The patch command now supports -l, and gethostname is now enabled by |
| 784 | default. The df command follows symlinks to get the actual device name. |
| 785 | Felix Janda added -m support to wc (for utf8).</p> |
| 786 | |
| 787 | <p>On the infrastructure side, the commands have now been grouped into |
| 788 | "posix", "lsb", and "other" subdirectories (for things required by Posix-2008, |
| 789 | the Linux Standard Base 4.1, and commands in neither). This affects menuconfig |
| 790 | and the actual source layout (toys/cp.c is now toys/posix/cp.c, and so on). |
| 791 | An android directory is planned (see the updated |
| 792 | <a href=roadmap.html#android>android roadmap analysis</a>).</p> |
| 793 | |
| 794 | <p>The FLAG_ macros for command option parsing and TT alias for the command's |
| 795 | global block are now automatically generated, commands should |
| 796 | #define FOR_commandname before #including <toys.h> to get the macros for that |
| 797 | command.</p> |
| 798 | |
| 799 | <p>An upgrade to the build infrastructure now allows commands with _ and - |
| 800 | in them, such as switch_root.</p> |
| 801 | |
| 802 | <p>Bugfixes: Avery Pennarun spotted a case where ls showed uid twice instead of |
| 803 | uid and gid, and that nice was using the wrong range of numbers. |
| 804 | The ls command also recursed inappropriately last time (not quite |
| 805 | properly converted for the dirtree changes last release), and now it's |
| 806 | fixed. Roy Tam pointed out a glitch in sh, and fixed df's percentage |
| 807 | calculation to match the POSIX spec. The kernel build didn't like our mktemp |
| 808 | and it does now. The wc command wasn't quite posix compliant (trailing spaces |
| 809 | break stuff). The ls command recursed inappropriately last time (not quite |
| 810 | properly converted for the dirtree changes last release), and now it's |
| 811 | fixed. The catv command wasn't displaying byte 255 correctly. Some lib |
| 812 | fixes (thinko in xpidfile). Fixed uname -m when running a 32 bit x86 binary |
| 813 | on an x86-64 host (it lies and says the system is i686, i586, or i486 depending |
| 814 | on what the toolchain that built the binary supported. This makes builds in |
| 815 | a 32 bit chroot on a 64 bit kernel break less.) The df command was checking |
| 816 | partitions in the wrong order (displaying undermounts instead of overmounts: |
| 817 | this used to work but some library code changed out from under it and it |
| 818 | wasn't updated to match until now). Felix Janda filled out the test suite |
| 819 | some more. The patch file creation logic got tweaked several times to |
| 820 | successfully apply more patches. Support for older (pre 2.10) glibc |
| 821 | versions was added to portability.h.</p> |
| 822 | |
| 823 | <p>Miscelaneous cleanups all around (mknod, sha1sum, logname), including a |
| 824 | rewrite of taskset to be less dependent on libc getting the headers right. All |
| 825 | the command headers should now point to the current relevant standards |
| 826 | document, where applicable.</p> |
| 827 | |
| 828 | <p>This news page had old news entries from before the relaunch moved into |
| 829 | a separate <a href=oldnews.html>oldnews</a> page.</p> |

| 887 | statically linked <a href=downloads/binaries>prebuilt binaries</a> should |
| 888 | actually be statically linked this time (thanks Ashwini Sharma for spotting |
| 889 | that).</p> |
| 890 | |
| 891 | <p>It's hard to figure out where to cut a release, because development |
| 892 | doesn't stop. "Long before now" is the obviuos answer, of course. |
| 893 | The project's maintainer also moved house during this development cycle, which |
| 894 | threw things off for a bit (so many boxes). Releases should hopefully be a bit |
| 895 | more frequent from here on.</p> |
| 896 | |
| 897 | <p>The big things Rob worked on this time were the new dirtree (directory |
| 898 | tree traversal) infrastructure, and a complete rewrite of ls using that |
| 899 | which should now implement all 26 posix options.</p> |
| 900 | |
| 901 | <p>Georgi Chorbadzhiyski added printenv, whoami, mkdir, mkfifo, chmod, chown, |
| 902 | chgrp, and uniq. He also added fraction and extension support to sleep (so if |
| 903 | you need a quarter-second sleep, it can do that now), and fixed a build bug |
| 904 | on slackware.</p> |
| 905 | |
| 906 | <p>Daniel Walter contributed a string to mode_t parser (in use by chmod and |
| 907 | mkdir -m). Ilya Kuzmich contributed comm. Elie De Brauwer added mountpoint, |
| 908 | vmstat, logname, login, and mktemp. Kevin Chase did some portability cleanups. |
| 909 | Pere Orga fixed some documentation.</p> |
| 910 | |
| 911 | <p>The "tac" and "clear" commands are now normal commands instead of shell |
| 912 | wrappers, and the header #includes have been cleaned up a bit to remove |
| 913 | deprecated functions and attempt to increase compatability with the bionic and |
| 914 | musl C libraries, "tail" should now use lseek() for large files, and "id" got |
| 915 | some cleanups and bugfixes.</p> |
| 916 | |
| 917 | <p>The new TOYBOX_FLOAT configuration option selects whether or not |
| 918 | to include floating point support (for embedded targets where that's |
| 919 | problematic).</p> |
| 920 | |
| 921 | <p>Several random bugfixes: unshare() might actually build portably now, |
| 922 | yes 'n' | cp -i should no longer bypass stdin and prompt via the tty, the |
| 923 | SUID support no longer drops permissions going through the toybox |
| 924 | multiplexer command, and a bugfix to xargs -0 means it should no longer |
| 925 | segfault. (I have a pending bug report about xargs not doing the full |
| 926 | posix whitespace handling that -0 obsoleted, but I'll deal with that next |
| 927 | release.)</p> |
| 928 | |
| 929 | <p>The build infrastructure is now automatically generating FLAG_ macros |
| 930 | for the options, but currently with the wrong names. Some more macro glue |
| 931 | is necessary, which I haven't quite figured out how to do yet.</p> |
| 932 | |
| 933 | <p>A defconfig toybox at the start of the $PATH has successfully built |
| 934 | Linux From Scratch (in my Aboriginal Linux project). The commands that |
| 935 | 'default n' in the config are often still broken, cleanup is ongoing. |
| 936 | (The new dirtree stuff broke several of them that haven't been converted |
| 937 | yet, but if I wait until everything works we won't have a release before |
| 938 | 1.0, so here's a checkpoint.)</p> |

| 975 | |
| 976 | <p>(For that release I did xargs, cal, truncate, unlink, nohup, tty, wc, link, |
