|
||||
(<a href=https://github.com/landley/toybox/releases/tag/0.8.2>git commit</a>)
|
||||
is finally out (only two months late).</p>
|
||||
|
||||
<p>The new commands this time are minor variants of existing ones
|
||||
(<b>dnsdomainname</b> is hostname -d, <b>arch</b> is uname -m), but about
|
||||
1/3 of toysh got implemented in pending, <a href=https://github.com/landley/mkroot>mkroot</a> got merged as a "make root" target (see Build),
|
||||
and Android's <a href=http://lists.landley.net/pipermail/toybox-landley.net/2019-August/010845.html>hermetic build</a>
|
||||
work continued resulting in a lot of fixes.</p>
|
||||
|
||||
<p>The android-specific <b>getprop</b>, <b>setprop</b>, <b>start</b>, and <b>stop</b>
|
||||
commands were removed from toybox because they grew dependencies on android
|
||||
libraries, and since toybox tries to avoid mandatory external dependencies
|
||||
they moved to another package.</p>
|
||||
|
||||
<p><u>Build</u>:
|
||||
The new "make root" target builds a simple toybox root filesystem,
|
||||
using scripts/mkroot.sh which is a stripped
|
||||
down version of the external <a href=https://github.com/landley/mkroot>mkroot</a>
|
||||
project merged into toybox. (Alas, at the moment it wants sh and route out
|
||||
of pending, which aren't quite load bearing yet.)</p>
|
||||
|
||||
<p>The new "scripts/mcm-buildall.sh" convenience script builds cross
|
||||
compilers based on gcc+musl multiple targets (arm, x86, mips, m68k, s390,
|
||||
microblaze...)
|
||||
using <a href=https://github.com/richfelker/musl-cross-make>musl-cross-make</a>,
|
||||
and a new scripts/cross.sh to easily cross compile for one or more targets
|
||||
using the resulting compilers. (This works with "make root", "make
|
||||
toybox", and other builds understanding the CROSS_COMPILE environment variable.)</p>
|
||||
|
||||
<p>Setting the environment variable ASAN=1 enables the
|
||||
llvm address sanitizer. (You may need to
|
||||
export ASAN_SYMBOLIZER_PATH on debian to use it, they add the version number to
|
||||
the filename in /usr/bin which confuses llvm.)</p>
|
||||
|
||||
<p>Patrick Oppenlander fixed make -j (our make is a wrapper around
|
||||
scripts/make.sh which was already doing a parallel build, but if you called
|
||||
make with -j it wouldn't wait for make.sh to finish and the build broke).</b>
|
||||
|
||||
<p>Lots of fixes for the MacOS build.</p>
|
||||
|
||||
<p><u>New options</u>:
|
||||
We upgraded <b>tar</b> to extract some older tarballs, <b>file</b> added -b and -s
|
||||
options and can also recognize older tarballs,
|
||||
some xz archives, .otf fonts, perf/simpleperf data files,
|
||||
android boot images, and dtb files. Upgraded <b>file</b> to show the device type
|
||||
for block and char devices, the target for symlinks, and it says _why_ it can't
|
||||
open a file.</p>
|
||||
|
||||
<p>Several commands ignore some options rather than erroring on them:
|
||||
<b>patch</b> ignores the -f -g# and --no-backup-if-mismatch options
|
||||
(all of which we were already doing by default anyway), and <b>xargs</b>
|
||||
ignores -P# (which requests parallel execution, maybe add it later but
|
||||
single threading works), and Denys Nykula made <b>wget</b> ignore
|
||||
--no-check-ceritificate and <b>gzip</b> ignore -n (again, we weren't doing
|
||||
either anyway) to satisfy pkgsrc.</p>
|
||||
|
||||
<p>William Haddon taught <b>diff</b> and <b>patch</b> to support special characters in path
|
||||
names (via quoting) and more timestamp formats.
|
||||
Eric Molitor implemented <b>nl</b> -v (with negative and zero starting values),
|
||||
and fixed a MacOS compatibility issue in the build scripts.
|
||||
Tom Cherry added <b>netcat</b> -U (UNIX domain socket support).
|
||||
Denys Nykula taught <b>wget</b> to call ftpget for ftp:// URLs.
|
||||
Ethan Sommer added ln -t and rmdir --ignore-fail-on-non-empty.
|
||||
Elliott Hughes added <b>grep</b> -R, <b>killall</b> -w, tar --mode,
|
||||
fixed <b>ls</b> -Z and spacing in -lZ and --full-time,
|
||||
added <b>xargs</b> --max-args and removed xargs -I (which we never actually
|
||||
supported) and tweaked the size calculation to more closely match other
|
||||
versions,
|
||||
added xargs -o and made -p read from /dev/tty, added <b>blkid</b> -s, SEC_TYPE for ext3,
|
||||
msdos, and ntfs, f2fs and ntfs LABEL, fixed vfat/ntfs UUID, and switched
|
||||
the endianness for UUID of msdos/ntfs/vfat, simplified the octal mode
|
||||
display in <b>lsof</b>, added <b>pidof</b> -x (thus making the default behavior _not_
|
||||
be -x).</p>
|
||||
|
||||
<p>When readdir() succeeds but stat() fails, <b>ls</b> now prints "??? ? ? filename"
|
||||
entries instead of "cannot access" errors. (Still trying to make ls / on
|
||||
android work more gracefully with the SELinux weirdness they added in 9.)</p>
|
||||
|
||||
<p>Added %C to <b>stat</b> and made it show device type in its default output,
|
||||
<b>cmp</b> now works
|
||||
with 1 argument (implicit - as second argument reading from stdin).
|
||||
<b>sed</b> added exit codes to the q command (q123), added Q, and fixed a
|
||||
bad error message with "!".
|
||||
Removed TAIL_SEEK config option (it just always does that now),
|
||||
<b>find</b> grew several new options (%Z, -true, -false, and -newerXY), <b>ln</b> added -T.
|
||||
The argument to <b>mktmp</b> --tmpdir is now optional.</p>
|
||||
|
||||
<p><u>Bugfixes</u>:
|
||||
The unshare probe bit-rotted so it was impossible to build <b>unshare</b>
|
||||
and <b>nsenter</b> on some distros.
|
||||
Commit 771e94e2a08 broke toybox's ability to say "unknown command" when
|
||||
you pointed a symlink at it that it that didn't correspond to a command,
|
||||
pointing a symlink at another symlink
|
||||
to make toybox run a command under a name it doesn't recognize
|
||||
(ln -s toybox sh; ln -s sh ash) had an off by one error,
|
||||
<b>ifconfig</b> no longer error_exits if the "read mac address" ioctl fails (Android N
|
||||
and later block that for non-root users to prevent device tracking).
|
||||
When the libcrypto library was disabled, md5sum was building commands it
|
||||
hasn't got built-in support for yet (like sha3sum) which acted like redundant
|
||||
copies of md5sum,
|
||||
<b>tar</b> wasn't correctly reading or writing sparse files with a hole at
|
||||
the end, and tar tzf blah.tar.xz was calling xz when it meant xzcat,
|
||||
<b>xargs</b> would spuriously fail on large memory systems (due to a missing
|
||||
"unsigned" in a typecast),
|
||||
<b>basename</b> can now remove suffixes starting with a dash,
|
||||
<b>cp</b> -r unlinks() an existing symlink before trying to
|
||||
recreate the symlink (otherwise cp -r into an existing directory will
|
||||
try to follow the existing symlink and create another symlink at its
|
||||
destination, failing if a file already exists there, which
|
||||
was confusing gentoo's package manager), <b>timeout</b> now produces the
|
||||
right exit code when the timed command intercepts the exit signal,
|
||||
and <b>hostname</b> -d no longer segfaults on machines with no domain name.</p>
|
||||
|
||||
<p>Denys Nykula fixed the <b>ftpget</b> freeze (it was sending REST instead
|
||||
of RETR), made <b>mv</b> work with a trailing slash in the source,
|
||||
fixed a <b>find</b> segfault,
|
||||
and made <b>env</b> always exec rather than recursing to a builtin
|
||||
(on the theory #!/usr/bin/env is expected to search the $PATH).</p>
|
||||
|
||||
<p>Elliott improved <b>killall</b>'s handling of long filenames, made <b>kill</b> work
|
||||
when killall5 is disabled (missing FORCE_FLAGS), fixed error reporting in
|
||||
<b>hostname</b>, fixed several things in <b>xargs</b>,
|
||||
made <b>printf</b> \c and \0 octal escapes work, fixed a <b>find</b> -name corner
|
||||
case (find src/*.c -name file.c) and find dangling symlink behavior,
|
||||
made some <b>rm</b> error messages consistent, fixed \x behavior in echo and
|
||||
printf, fixed linestack.c's buffer length for utf8 U+XXXX escape printing,
|
||||
fixed a race in <b>losetup</b>, fixed <b>grep</b> -F with multiple matches on the same
|
||||
line and an -I failure in the existing grep tests, made <b>readlink</b> notice
|
||||
when it has more than one argument, and made various
|
||||
fixes to <b>modinfo</b>.</p>
|
||||
|
||||
<p>Ethan Sommer reported that <b>stat</b> of an suid/sticky file output 5 digits of
|
||||
octal stat date instead of 4.
|
||||
Rob fixed an unaligned access in <b>grep</b>. Alessio Balsini removed an incorrect
|
||||
null termination in <b>losetup</b>.
|
||||
Jarno Mäkipää fixed <b>hexedit</b>
|
||||
scrolling up and down on older terminals, and fixed <b>ls</b> segfaulting with a broken
|
||||
(non-UTF8) locale (didn't expect wcrtomb to return -1).
|
||||
Andrew Ilijic made ls put 2 spaces between columns like other implementations
|
||||
(which helps when terminals get confused and apply UTF8 combining characters
|
||||
to the space after a filename).
|
||||
</p>
|
||||
|
||||
<p><u>Library</u>:
|
||||
Added dlist_lpop() to use a dlist as a stack (it removes the last entry
|
||||
instead of the first), and dlist_pop() now works on a dlist_terminate()d list.
|
||||
DIRTREE_STATLESS returns entries we couldn't stat() (with a zeroed ->st
|
||||
field, and ->again |= 2), but filling in the file type from readdir().
|
||||
Coversions between signal names and numbers now include all the Linux signals,
|
||||
not just posix ones. The functions sig_to_num() and num_to_sig() moved into
|
||||
lib/portability.h, because MacOS has different signals.
|
||||
TOYFLAG_MAYFORK allows commands to run in toysh's process without forking,
|
||||
but also makes them accessable from the toybox multiplexer or standalone.
|
||||
A MAYFORK command has to clean up after itself (even in error paths) and
|
||||
can't discard anything we need to keep (such as closing stdout).</p>
|
||||
|
||||
<p>Elliott did a big xbind/xconnect cleanup (adding xbindany and xconnectany),
|
||||
taught xregcomp that an empty regex matches the whole line
|
||||
(because FreeBSD, and thus MacOS, doesn't already do that), and
|
||||
replaced several uses of get_line() (which does single byte reads)
|
||||
with getline() (which doesn't).</p>
|
||||
|
||||
<p><u>Plumbing</u>:
|
||||
"make clean" doesn't produce a screenful of unnecessary output now,
|
||||
rm, ln, cp, kill, and netcat use the FLAG() macros now, makedevs uses the new
|
||||
GLOBALS naming format, timeout now uses xwaitpid(), and we fixed an
|
||||
off by one error in xwaitpid().</p>
|
||||
|
||||
<p>Elliott removed a workaround for old NDK versions from getconf and
|
||||
moved sort off of get_rawline() (which let us remove it).
|
||||
Rob undid some loop unrolling in md5sum/sha1sum (we have libcrypto if you want
|
||||
an assembly optimized version instead of an understandable version).</p>
|
||||
|
||||
<p>Android ndk-r20 doesn't define the __ANDROID_NDK__ symbol, so we switched
|
||||
to using clang's __has_include() (which is an undefined macro and thus a NOP
|
||||
resolving to false on gcc).</p>
|
||||
|
||||
<p><u>Pending</u>:
|
||||
Rob did a lot of work on toysh: continuation support works (it knows when to ask
|
||||
for another line of text and when to run what it's got), as do
|
||||
nested if/else/elif statements, and while and for loops (supporting "for i"
|
||||
and "for i in", but not for ((;;)) yet).
|
||||
It parses pipes and redirections but doesn't perform them yet.
|
||||
The next big todo chunk is environment variable resolution.
|
||||
</p>
|
||||
|
||||
<p>Gavin Howard fixed some bugs in bc, such as not returning error when raising
|
||||
zero to a negative power.
|
||||
Jarno Mäkipää continues to extend vi, adding yank and push, support for tabs,
|
||||
rewriting delete, changing the drawing code, etc. Elliott also added several
|
||||
fixes and features to vi,
|
||||
fixed host to cope with large DNS responses, switched crontab to
|
||||
use getline(), did work on man, fixed fixed several things in dd,
|
||||
implemented diff --strip-trailing-cr and made diff not need /tmp.
|
||||
Mike Bennett added extended attribute support to ip.c's route change.</p>
|
||||
|
||||
<p><u>Test suite</u>: The killall and pgrep tests were having occasional
|
||||
spurious failures due to a race condition (the test script would fork()
|
||||
to call sleep and for just a moment there were two instances of the test
|
||||
script, reporting an extra process if killall or pgrep ran then).
|
||||
|
||||
<p>Elliott Hughes did a lot of work on the test suite: add kill -l tests,
|
||||
make losetup.test notice (and skip) if loopback
|
||||
devices area already in use, blkid.test can TEST_HOST e2fsprogs blkid now,
|
||||
modinfo.test notices (and skips) if there's no /proc/modules or modules
|
||||
directory, ifconfig.test skips if "dummy0 up" fails and disabled the
|
||||
pointtopoint tests entirely (the kernel never supported it?),
|
||||
truncate.test is less
|
||||
confused by SELinux, hostname.test can run some tests as non-root,
|
||||
addressed a race condition in killall.test on slow systems,
|
||||
made chgrp.test, chown.test, and tar.test handle an empty /etc/passwd or /etc/group
|
||||
(we were checking whether they were _there_ but some android devics have
|
||||
empty ones),
|
||||
fixed a couple things in env.test, extended killall.test to explicitly cover
|
||||
long and short names (and not assume the shell is /bin/sh), taught split.test not to rely on bash process substitution,
|
||||
added missing TZ=utc to touch.test, fixed cp.test to pass for root
|
||||
or with a restrictive umask, and fixed the FAILCOUNT arithmetic to use more portable
|
||||
$(()). Elliott also made some tests more flexible (find.test can handle any
|
||||
error message about symlink loops, etc), and disabled others (such as du)
|
||||
when SELinux is enabled.</p>
|
||||
|
||||
<p>Rob taught testcmd not to use the shell builtin for TEST_HOST unless there
|
||||
isn't one in the $PATH, work if $PWD has a space in it,
|
||||
and make kill.test stop testing the shell builtin
|
||||
insead of the command, quieted tests that were producing output
|
||||
other than their PASS/FAIL line, and made NOSPACE tests ignore the
|
||||
presence/absence of leading/trailing whitespace as well as differences
|
||||
in the amount of space.</p>
|
||||
|
||||
<p><u>Documentation</u>:
|
||||
The <a href=roadmap.html>roadmap</a> got freshened up a bit, with updates
|
||||
for android from Elliott.
|
||||
In <a href=design.html>the design page</a> the Features section starts with
|
||||
4 new paragraphs about the scope of toybox, and a new License section talks
|
||||
about 0BSD.
|
||||
The "./toybox --help" output now explains how to do install_flat by hand.</p>
|
||||
|
||||
<p><u>Sheer pedantry</u>:
|
||||
Elliott fixed a double close in loopfiles_lines() so strace doesn't
|
||||
have an EBADF in it, and added a missing "static" in lib/net.c.</p>
