2019-09-13timeout: fix exit status for sneaky subprocesses.Elliott Hughes
There's nothing to stop a subprocess from catching our SIGTERM on timeout and exiting, causing us to incorrectly report that it didn't time out. Android's ART has a utility that does exactly this. Explicitly catch this case, and add corresponding tests. Bug: http://b/141007616
2019-03-13timeout: remove bogus depends-on.Elliott Hughes
2019-03-10Add TOYFLAG_ARGFAIL() to allow argument parsing failures to exit with value.Rob Landley
2019-03-10timeout: --foreground, --preserve-status, and --signal.Elliott Hughes
--signal is simply a synonym for the exiting -s. --foreground disables functionality we didn't yet have: putting the child into a new process group. I've added the functionality and the flag to disable it. --preserve-status also makes it clear that our exit statuses didn't match the coreutils version. In addition to callers that use --preserve-status to get away from this madness, I also have callers that check for specific exit values. This patch implements --preserve-status but also fixes all the other exit statuses. (The "125" exit value is broken for toybox in the same way that `toybox grep --whoops ; echo $?` is. To fix this, we'd need some way to signal that command-line parsing failures should exit with a different value than the usual 1 --- 2 for grep, 125 for timeout. I've done as much as grep manages, and left a TODO.) Also add timeout tests. I couldn't think of an easy test for --foreground, so I tested that manually with strace. Also add some newlines to the `toybox --help` output to make it easier to find the different sections, and expand the section on durations to call out that fractions are supported as a matter of policy. As long as timeout and sleep have text describing the duration syntax, make them the same. (Personally I'd remove both in favor of the `toybox --help` output, but as long as they're duplicated, keep them consistent.) Also remove the SLEEP_FLOAT variant --- xparsetime means that sleep no longer requires floating point to support sub-second resolution.
2019-01-25OpenEmbedded needs commands installed in specific places.Rob Landley
2018-11-02Convert more option vars to the new (single letter) coding style.Rob Landley
2018-10-21Add % to lib/args.c (long time in milliseconds), add xmillitime(), redoRob Landley
xparsetime() not to need floating point, adjust callers.
2018-10-07Fix build break on x32 target.Rob Landley
2017-05-26Be more consistent about periods in help text.Elliott Hughes
2016-07-29Izabera reporeted that FLAG_v was never checked in timeout. (Oops.)Rob Landley
2015-09-29Make defconfig build for nommu.Rob Landley
Adds XVFORK() macro, teaches xpopen_both() to call /proc/self/exe with NULL argv (and converts cpio -p to use that), adds TOYBOX_FORK guards to some unconverted commands.
2015-09-23Add xvfork() as a static inline and use it from various places.Rob Landley
Note: vfork(), like fork(), can return -1 if too many processes, and we should notice and fail loudly.
2015-03-10Use xsignal() instead of signal().Rob Landley
2015-03-09Fix thinko (don't &toybuf to get scratch space) and add -v option.Rob Landley
2015-02-07Make toy_exec() check if argc is in optargs and deal with it there so we ↵Rob Landley
don't need a separate xexec_optargs().
2014-05-31Introduce xfork() and make commands use it, and make some WEXITSTATUS() use ↵Rob Landley
WIFEXITED() and WTERMSIG()+127.
2013-07-17Add timeout, factoring out common code from sleep.Rob Landley
