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
2019-03-10Make xsendfile() variants handle -1 length properly again.Rob Landley
2019-03-10Don't redirect stderr or xexec() error hidden.Rob Landley
2019-03-10Make multiple sendfile variants, and teach xpopen_both() to use existingRob Landley
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
Broke the bionic build: external/toybox/toys/net/netcat.c:188:37: error: incompatible pointer types assigning to 'sigjmp_buf *' (aka 'long (*)[33]') from 'jmp_buf *' (aka 'long (*)[32]') [-Werror,-Wincompatible-pointer-types] if (toys.optflags&FLAG_L) NOEXIT(child = XVFORK()); ^~~~~~~~~~~~~~~~~~~~~~~~ external/toybox/lib/lib.h:375:19: note: expanded from macro 'NOEXIT' #define NOEXIT(x) WOULD_EXIT(_noexit_res, x) ^~~~~~~~~~~~~~~~~~~~~~~~~~ external/toybox/lib/lib.h:367:16: note: expanded from macro 'WOULD_EXIT' toys.rebound = &_noexit; \ ^ ~~~~~~~~ 1 error generated.
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

2018-12-17Only set FLAGS_NODASH when arguments didn't have a dash.Rob Landley
This (eventually) lets "ps ax" and "ps -ax" behave differently.
