From 502b10c2ab6bb273bf280ba355fa30869b955d56 Mon Sep 17 00:00:00 2001 From: Elliott Hughes Date: Sat, 9 Mar 2019 17:41:49 -0800 Subject: timeout: --foreground, --preserve-status, and --signal. --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. --- toys/posix/sleep.c | 14 ++++---------- 1 file changed, 4 insertions(+), 10 deletions(-) (limited to 'toys/posix/sleep.c') diff --git a/toys/posix/sleep.c b/toys/posix/sleep.c index 0381c107..846df80c 100644 --- a/toys/posix/sleep.c +++ b/toys/posix/sleep.c @@ -11,18 +11,12 @@ config SLEEP bool "sleep" default y help - usage: sleep LENGTH + usage: sleep DURATION - Wait before exiting.
