2019-06-03tail: fix macOS build.Elliott Hughes
Trivial breakage from the recent refactoring. Also add tail to the default config for macOS. I'm still unconvinced that CONFIG_TAIL_SEEK makes sense in a world where inotify support is always built in, but that's an argument for another day...
2019-06-01Teach file to recognize xz archives and old style tarballs.Rob Landley
2019-05-25find: add -printf support.Elliott Hughes
This only implements the format specifiers that I've seen used in the wild (which is actually a significant fraction of the total supported by findutils' find). The most obvious gap is in the time support. I'm happy to add more, but didn't want to add stuff "just because". I'd say %A@, %C@, and -- for SELinux users -- %Z are probably the most plausibly useful formats still missing. I don't think the human-readable date formatting is particularly useful unless someone's seen it actually used in the wild. The %T+ "full ISO" format being the most likely exception to that. Anyway, this is enough for me get started building AOSP with toybox find.
2019-05-25Move notify.c into portability.c (collate the #ifdefs), move global variablesRob Landley
into a structure passed as arguments, add x prefix to functions that can fail, add overflow test.
2019-05-25tail: support -f on BSD too.Elliott Hughes
Factor out the inotify code and add a kqueue equivalent. Specifically tested on macOS 10.14, but I assume this works for other BSDs too, given that I worked from the FreeBSD man page...
2019-05-19Don't complain about short writes to stdout.Rob Landley
2019-05-16Add human_readable_long() for more than 3 digits of output.Rob Landley
2019-05-13Comment tweak.Rob Landley
2019-05-12Fix readlink0() to blank string on failure.Rob Landley
2019-05-11Teach tar to extract type 'S' sparse file headers.Rob Landley
2019-05-06Greatly simplify and speed up regexec0() using REG_STARTEND.Rob Landley
This is a 15 year old freebsd extension (presumably thus also available on MacOS) that glibc adopted in 2004, uClibc adopted in 2005, and bionic supports. The only thing that DOESN'T support it is musl, once again because its maintainer explicitly decided not to (https://www.openwall.com/lists/musl/2013/01/15/26), so add an #ifdef to let musl stay uniquely broken. (It'll stop at first NUL, everything else can match NULs). Finally fixes "s/x/y/g on a megabyte line of x's takes forever" issue.
2019-05-04Optimize regexec0() for long lines.Rob Landley
Don't strlen() to find NUL to skip to until after we've confirmed first section hasn't got a match (by calling regexec() on it).
2019-05-03Add a couple comments.Rob Landley
2019-05-03env: fix case where a variable is replaced.Elliott Hughes
Found when trying to update the toybox prebuilt used for the Android build. Also add the corresponding test.
2019-05-02Android moved the scheduler policy functions in Q.Elliott Hughes
They're forwarded to libprocessgroup, but we may as well go straight to the source since neither library is in the NDK anyway. This code is unfortunate because it means that even `toybox true` ends up pulling in a JSON parser at runtime, because ps might call get_sched_policy/get_sched_policy_name. I'll experiment with dlopen-on-demand in portability.c and see whether the savings are worthwhile, but for now at least use the current library directly so we can save *one* dlopen!
2019-04-22struct deflate no longer lives in TT so must be explicitly zeroed, and useRob Landley
libbuf instead of toybuf in lib/
2019-04-21Shouldn't need clearenv() for macosx now we've got xclearenv.Rob Landley
2019-04-20Add xunsetenv() for the error checking.Rob Landley
2019-04-20New xsetenv() plumbing (repeatedly set same environment variables withoutRob Landley
leaking memory), and mod env command to test it.
2019-04-16Add argument to xflush() so it can test for stdout err without flushing.Rob Landley
2019-04-12Make help text spacing consistent.Rob Landley
2019-04-11scan_key: support more terminals.Elliott Hughes
Although we can get away with ignoring termcap/terminfo on the output side by restricting ourselves to generally-supported escape sequences, the input side is trickier because we need to support the sequences sent by common terminals. Luckily, this isn't is as bad as it sounds because only Home/End commonly differ. But it does mean we need a slightly different implementation to deal with the many-to-one mapping. Since we can't use TAGGED_ARRAY for this (without inflicting pain on all the callers) I've also switched to OR-ing in the modifier keys, so we have (say) KEY_UP|KEY_SHIFT rather than a separate KEY_SUP. This also generalizes better should we ever need to support multiple modifiers at once. To reduce the number of #defines, I've also switched from KEY_F1, KEY_F2, and so on to KEY_FN+1, KEY_FN+2, and so on. This isn't obviously necessary, and easily undone if we'd rather have move #defines in return for slightly more natural naming. To enable all this, I've inverted scan_key and scan_key_getsize so that scan_key_getsize is now the underlying function, and we don't waste all the top bits encoding width and height between scan_key and scan_key_getsize. Tested by pressing Home and End in hexedit in all of the terminals available to me.
2019-04-02Don't leak stdout pipe filehandle into children.Rob Landley
2019-04-02Have xflush() only flush stdout (that's all it checks errors on),Rob Landley
and tweak a couple comments.
2019-04-02Don't emit random -EPIPE error messages in a pipeline, just exit silently.Rob Landley
2019-03-27xabspath: use O_PATH for dirfd.Elliott Hughes
SELinux on Android is unhappy if you try to read "/": avc: denied { read } for name="/" dev="dm-3" ino=2 scontext=u:r:hal_dumpstate_impl:s0 tcontext=u:object_r:rootfs:s0 tclass=dir permissive=0 That could happen via the open of ".." too, and potentially any other directory might have similar restrictions, so move all of the open calls to using O_PATH. O_PATH seems more intention-revealing given what this function is doing anyway.
2019-03-27Change fileunderdir() to return abspath to file.Rob Landley
2019-03-26xabspath: use O_PATH.Elliott Hughes

2019-03-26Make touch use xparsedate() (result: -t and -d the same, autodetects format),Rob Landley
and fix tests to pass on host too.
2019-03-24Factor out xparsedate() and xvali_date() into lib.Rob Landley
2019-03-17Fix xstrndup() bug.Rob Landley
Now there's a second user... the libc function already null terminates at len+1, and it doesn't malloc the full size if strlen() smaller so the redundant termination stomped unallocated memory. Oops. sort.c never noticed because it calculated length to truncate or copy existing string, so never hit this.
2019-03-10Add TOYFLAG_ARGFAIL() to allow argument parsing failures to exit with value.Rob Landley
2019-03-10Add missing isatty(3) call.Elliott Hughes

stdin/stdout filehandles.
2019-03-09Half-finished su change checked in, sorry.Rob Landley
2019-03-07Add reset_env() and make su and login use it. Do long-delayed login cleanup.Rob Landley
2019-03-04Consistently use ARRAY_LEN.Elliott Hughes
2019-02-23Bumper typo cleanup.Elliott Hughes
Inspired by some of the small patches that have gone by recently. Limited to only things found in `generated/help.h`, plus a wider cleanup for the more common "milisecond" typo.
2019-02-20Make xgetaddrinfo() return a wildcard address for NULL host, and xconnbind()Rob Landley
always set SO_REUSEADDR (which won't reuse an active port but merely disables the strange "but reply packets might come in after we close the socket" hand-wringing timeout nobody's cared about in decades.)
2019-02-15Fix typos: e.g. change "cannonical" to "canonical".Jason Spiro
2019-02-13Move nanomove(), nanodiff(), union socksaddr, and xrecvwait() to lib.Rob Landley
2019-02-05The android NDK does not appear to have adjtime(). (It has the syscall, andRob Landley
it has clock_settime(), but not the libc adjtime() function...) *shrug* Stub it out in portability.h.
2019-02-03William Djupström pointed out that xexec() lost the absolute path check.Rob Landley
2019-01-22Fix sigjmp_buf/jmp_buf mismatches.Elliott Hughes

2019-01-18Teach xpoll() to measure time if interrupted, and wait for what's left.Rob Landley
2019-01-16Move xsendto() to lib/net.c.Rob Landley
2019-01-12sed: add -z.Elliott Hughes
Used to construct SELinux policies in the AOSP build. I left loopfiles_lines with its hard-coded '\n' because although cut(1) also has a -z option, I can't find any case where it's used in any of the codebases searchable by me. (And fmt(1), the other user, doesn't even have the option.) YAGNI. Bug: http://b/122744241
