2016-08-18Change xgetpwnamid/xgetgrnamid to xgetuid/xgetgid returning the id numberRob Landley
instead of a struct. This means it can return "12345" even if that user/group doesn't exist in /etc/passwd and similar. All the users were immediately dereferencing it to get pw_uid or gr_gid anyway, so just return it directly and adjust the users. This fixes things like "chown 12345:23456 filename".
2016-08-13Document deviations from posix for echo.Rob Landley
2016-08-13Add TOYFLAG_NOHELP to disable --help processing for individual commands,Rob Landley
apply it to "true" and "false".
2016-08-13Move getusername/getgroupname to lib. (Return name or string representationRob Landley
of number, but never NULL. Both returned in static buffer good through next call.)
2016-08-04Make xopen() skip stdin/stdout/stderr, add xopen_stdio() if you want stdout,Rob Landley
add xopenro() that takes one argument and understands "-" means stdin, and switch over lots of users.
2016-08-01Fix touch(1) date parsing on tzcode-derived systems.Elliott Hughes
The IANA tzcode implementation of mktime (used on Android and BSDs) sets errno in some cases where it doesn't return -1 to indicate failure, so the existing test always failed on those systems. I don't think glibc ever sets errno (which is fine by ISO C, but not POSIX). Other uses of mktime in toybox are already fine. This one would have been caught by the existing tests if I was running them on the device :-(
2016-07-26Move regexec0 into lib (regexec that takes length and matches after NUL).Rob Landley
2016-07-23Usischev Yury pointed out that id shouldn't use exit() directly.Rob Landley
2016-07-23Usischev Yury pointed out a use after free error.Rob Landley
2016-07-13Increase ps' default RSS and VSIZE widths.Elliott Hughes
This is enough for everything on Android and everything except Java on my desktop. Even desktop Chrome fits!
2016-07-12Implement NOP find -noleafRob Landley
2016-07-05Don't try to guess the build id type in file(1).Elliott Hughes
They're really just arbitrary byte sequences of arbitrary length. Sure, a 20-byte sequence is _probably_ a SHA-1, but there's no way to know, so let's stop pretending...
2016-07-04Fix a bug (octal digits are 0-7, not 0-8) and deal with a case where posixRob Landley
is explicitly outright insane (%b handles octal escapes differently for no obvious reason).
2016-07-03Promote file.Rob Landley
2016-06-30Add patch -d and --dry-runRob Landley
2016-06-30Teach wc to do -cm together. Fix testsuite so TEST_HOST passes too.Rob Landley

2016-06-17Make it clearer that CMD is the thread name.Elliott Hughes
It should come as no surprise to those who followed the development of this that it's not well known which of the various names is actually the thread name. Adding "thread" to the ps --help output seems like a good idea. I'm also assuming that "stat2" was meant to read "stat[2]", since that's how it mostly appeared on the list while discussing this. Still fits in 80 columns.
2016-06-15Add readlink0() and readlinkat0() which null terminate the data.Rob Landley
2016-06-15The glibc bug at https://sourceware.org/bugzilla/show_bug.cgi?id=17829Rob Landley
continues to get worse, and now can't handle INT_MAX/2 either. So our first workaround _also_ broke. But posix says "A negative precision is taken as if the precision were omitted." and that _doesn't_ trigger the glibc bug, so use that instead.
2016-06-10Shuffle arguments around (TNAME->NAME->COMM->CMD), working around posixRob Landley
constraints while still trying to get sane behavior. Discard the old CMD, move COMM to CMD, move the old NAME to COMM, and move TNAME to NAME. Posix assumes argv[] is the only source of process name data, but Linux has three sources (/proc/$PID/cmdline, /proc/$PID/exe, /proc/$PID/stat field 2) and android uses multiple sources simultaneously to identify its processes and threads. Toybox ps also assumes that the field names displayed in the headers can be fed to -o to get that output, which is an assumption posix's ps spec clearly does not have. Before we were erring on the side of posix, now we're erring on the side of sanity. CMD now shows stat[2], all the time. The posix -f behavior change is now just an ARGS=CMD alias in the -f default command line, which -o overrides. (Before -f changed the behavior of -o CMD, which is closer to what posix says but is _insane_ and we've stopped doing it.) COMM now shows /proc/$PID/exe minus the path. (I'm aware posix says argv[0] here, but it says argv everywhere.) NAME is now argv[0] of $PID. TNAME went away. Both $COMM and $NAME show the data for $PID, which is a thread's parent process when $TID != $PID.
2016-06-10Revert commit e02e41373ea3, we're always initializing the TNAME stringRob Landley
field (that's the ptb/tb switching in get_ps) so it's never blank, so this doesn't trigger. (Conditionally initializing it would save runtime memory, but at the expense of more complex code.)
2016-06-10HACK: restore Android ps behavior.Elliott Hughes
"NAME" is no longer doing what we want; "TNAME" is what "NAME" used to be, except that "TNAME" implies -T. This patch switches us over to "TNAME", disables the implicit -T. Change-Id: I5553703d3939b24eaf39976162d2f75a591e1ce8
2016-06-09Fix dangling link after cp commandKyungsik Lee
"toybuf" should be initialized before calling symlinkat() or dangling link could occur.
2016-06-08Fix ps bug, last field wasn't expanding to width.Rob Landley
(Still fixing the fallout from that "Don't truncate number fields" logic rewrite.)
2016-06-08Change the TNAME behavior to "Show parent argv[0]. If that's blank, showour ↵Rob Landley
argv[0]. If that's blank, show [stat2]." That way threads show their parents, parents show themselves, and kernel threads show the [stat2] name.
2016-06-07Izabera pointed out that cmp -ls are contradictory.Rob Landley
2016-06-04Basic success/failure return from pgrep/pkill.Elliott Hughes
The man page says they also return 2 for syntax errors and 3 for "fatal error: out of memory etc", but I don't know how to implement that and don't need it (or have any reason to believe anyone needs it). Bug: 29092208
2016-06-04ps: Show [stat2] for any otherwise blank process name field, expand TNAME to 27,Rob Landley
use generated constant for stat field parsing loop.
2016-05-31In cp -a, don't complain if non-root user can't chown, failure is expected.0.7.1Rob Landley
2016-05-30Add output path to cp error message filenames.Rob Landley
2016-05-27Add -o TNAME for android, fix display of last field (retain left justifificationRob Landley
when trimmed for screen width), make ARGS path trimming logic work with spaces in path.
2016-05-24The "show parent command path" commit changed the criteria for active nodes,Rob Landley
and the collate logic wasn't updated. (Oops.)
2016-05-23Fix remaining pkill tests.Elliott Hughes
I don't know that anyone cares, but these failures made me think I'd broken something while testing the -SIGNAL patch. The -s parsing wasn't taking into account that -s 0 is a special case, and the -o test was assuming that pkill can tell the difference between two processes started at roughly the same time. Hopefully there's higher-resolution data available that can avoid the need for yet another sleep in the tests.
2016-05-23Fix pkill -9.Elliott Hughes
This fixes the existing test. Internal Android bug 28877702. I've left -l as-is, even though the desktop doesn't support that.
2016-05-22Don't truncate number fields for anything but right edge of screen, insteadRob Landley
let them overflow and try to reclaim extra space from later short fields.
2016-05-22Make -o COMMAND show parent command path for threads, and use saved lengthRob Landley
calculations instead of doing strlen() on strings again to store lengths.
2016-05-22Comment and help text tweaks.Rob Landley
2016-05-20Add bufgetgrgid()Rob Landley
2016-05-17Add bufgetpwuid. (Repeated calls to getpwuid() are really expensive.)Rob Landley
2016-05-16Add top -ORob Landley
2016-05-05Add top -H.Elliott Hughes
Also enable the same behavior we have with ps, where adding a thread-related field implies that you're interested in threads. Also clean up the help text slightly --- we're still not including the TOP_COMMON help, but at least when we do, we'll have each option covered with no duplicates.
2016-05-05"top -b -n1" should end with a newline.Elliott Hughes
The use of TT.time to determine whether to use \r or \n is a little odd, but let's stick with that for now. Correct the spelling of millitime and add a test.
2016-05-04Elliott says -T should fetch threads even when not displaying thread fields.Rob Landley
2016-05-04Simplify ps android scheduling policy fetch slightly.Rob Landley
2016-04-30Add a ps "PCY" field for Android scheduling policy.Elliott Hughes
