2020-01-09ls.c: just use getxattr()/lgetxattr().Elliott Hughes
bionic works around the fact that you can't use an O_PATH fd with fgetxattr(2), but glibc doesn't. Fixes https://github.com/landley/toybox/issues/158.
2020-01-08Implement readelf(1).Elliott Hughes
Basic readelf(1) implementation, with output close enough to the binutils version to be usable with scripts that expect the binutils version. This started as an implementation of nm(1) until I realized that I almost always want readelf instead, and that you actually have to do much of the work needed for readelf just to implement nm. Arguably nm (being part of POSIX) belongs in toybox while readelf doesn't. An argument could also be made that neither really belongs in toybox, belonging in a separate set of development tools (such as binutils or the LLVM binutils). Doesn't support most of the architecture-specific stuff, most notably relocations, but is aware of things like ARM exidx sections and the common register state notes in core dumps for the "big four" architectures: arm, arm64, x86, and x86-64. Doesn't support symbol versions (but probably should). Doesn't support section groups or the -t "section details" (which is a long form of -S "section headers" that I've never seen used in practice and which isn't part of -a). Doesn't support dumping unwind info or the hash table bucket histograms. Reuses the table of ELF architectures from file(1). Not fuzzed, but successfully parses all the ELF files in my Ubuntu 18.04 system's lib directories. Attempts to exit with an error when presented with an invalid ELF file rather than struggle on as binutils seems to.

2020-01-06date.c: add a few more important specifiers to --help.Elliott Hughes
Odd (and un-toyboxy) that we advertise the locale-specific output formats but not the ISO ones :-)
2020-01-06date.test: defuse a time bomb.Elliott Hughes
One of these tests fails in the gap between the locale it's run in changing the year and Europe/Berlin's changeover (caught by our automated testing, which tends to celebrate every new year by finding mistakes in tests like this). Another test has been failing consistently since 2020 because the default date output format includes the day of the week. Rather than implement Zeller's Congruence in the shell, explicitly use a format that doesn't include the day of the week for that test (and reuse the now-fixed calculation of the current year used by the other year-sensitive test).

2020-01-03Only free the environment variables we didn't inherit from exec.Rob Landley
2020-01-03Finish cd, make help -ahu unconditional, fix expand memory cleanup path,Rob Landley
set $HOME $PWD and $OLDPWD, fix prompt \w, shuffle some functions around to avoid prototypes, implement tilde expansion, add FORCE_COPY.
2020-01-03No, optflags gets cleared by toy_init(), use toys.rebound instead.Rob Landley
2020-01-03Add MAYFORK to "help", teach it to behave differently when called as aRob Landley
builtin, and add -u.
2020-01-01Use FLAG() macros.Rob Landley
2020-01-01Add MAYFORK to more pseudo-builtins.Rob Landley
This doesn't (yet) add shell builtin awareness to time, kill, or pwd, just lets them run in the shell process.
2020-01-01Factor out array_add(), replace argxtend().Rob Landley

Clear the last byte of the allocated buffer.
2019-12-26Fix setsid with vfork, redo command line arguments.Rob Landley
Switch -t to -c (like man page says), add -w (wait) and -d (detach from tty)
2019-12-23Toysh passes two tests now! Woo! (Otherwise, does not remotely work right now.)Rob Landley
2019-12-23Add "texpect" and add a couple simple examples to sh.test.Rob Landley
2019-12-22gzip: reject non-gzip files in zlib path.Elliott Hughes
It turns out that zlib defaults to just copying data verbatim if the input isn't in gzip format, rather than rejecting it. Explicitly add a check that zlib isn't doing that. (The toybox inflation path already errors out.) Also add the missing test.
2019-12-22Streamline init for NOFORK (fewer unnecessary syscalls for shell builtins).Rob Landley
2019-12-22Bugfix: tee with no arguments was writing to stdout twice.Rob Landley
Add basic smoketest while we're at it.

2019-12-20Making sh single build work broke other single builds. Fix them again.Rob Landley
2019-12-20patch: support [FILE [PATCH]] arguments.Elliott Hughes
POSIX only mentions -i/stdin, but GNU patch -- and Larry Wall's patch 1.3, found via https://en.wikipedia.org/wiki/Patch_(Unix) -- also support supplying the name of the file to patch and the name of the patch file as optional arguments. The AOSP build makes use of this syntax to patch snakeyaml to remove references to java.beans.* stuff.

2019-12-14dirtree.c: avoid spurious EINVAL warnings.Elliott Hughes
An Android engineer complained that they were seeing this when not running as root: $ adb shell ls ls: ./postinstall: Invalid argument ls: ./init: Permission denied ls: ./data_mirror: Invalid argument ls: ./init.environ.rc: Invalid argument ls: ./metadata: Invalid argument acct adb_keys apex From strace, it was here: newfstatat(4, "adb_keys", 0x7fc67eca88, AT_SYMLINK_NOFOLLOW) = -1 EACCES (Permission denied) readlinkat(4, "adb_keys", 0x5e843c7720, 4095) = -1 EINVAL (Invalid argument) So stop looking at st.st_mode (and then deciding to do a readlinkat()) if we didn't actually successfully stat().
