Johannes Sixt	04422c74c8	t0005: skip signal death exit code test on Windows The test case depends on that test-sigchain can commit suicide by a call to raise(SIGTERM) in a way that run-command.c::wait_or_whine() can detect as death through a signal. There are no POSIX signals on Windows, and a sufficiently close emulation is not available in the Microsoft C runtime (and probably not even possible). The particular deficiency is that when a signal is raise()d whose SIG_DFL action will cause process death (SIGTERM in this case), the implementation of raise() in msvcrt just calls exit(3). We could check for exit code 3 in addition to 143, but that would miss the point of the test entirely. Hence, just skip it on Windows.

Jeff King	e828908aa9	t0005: test git exit code from signal death When a sub-process dies with a signal, we convert the exit code to the shell convention of 128+sig. Callers of git may be relying on this behavior, so let's make sure it does not break. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Johannes Sixt	0e418e568f	t0005: work around strange $? in ksh when program terminated by a signal ksh93 is known to report $? of programs that terminated by a signal as 256 + signal number instead of 128 + signal number like other POSIX compliant shells (ksh's behavior is still POSIX compliant in this regard).

Jeff King	0ea8039644	t0005: use SIGTERM for sigchain test The signal tests consists of checking that each of our handlers is executed, and that the test program was killed by the final signal. We arbitrarily used SIGINT as the kill signal. However, some platforms (notably Solaris) will default SIGINT to SIG_IGN if there is no controlling terminal. In that case, we don't end up killing the program with the final signal and the test fails. This is a problem since the test script should not depend on outside factors; let's use SIGTERM instead, which should behave consistently.

Jeff King	4a16d07272	chain kill signals for cleanup functions If a piece of code wanted to do some cleanup before exiting (e.g., cleaning up a lockfile or a tempfile), our usual strategy was to install a signal handler that did something like this: do_cleanup(); /* actual work / signal(signo, SIG_DFL); / restore previous behavior / raise(signo); / deliver signal, killing ourselves */ For a single handler, this works fine. However, if we want to clean up two _different_ things, we run into a problem. The most recently installed handler will run, but when it removes itself as a handler, it doesn't put back the first handler. This patch introduces sigchain, a tiny library for handling a stack of signal handlers. You sigchain_push each handler, and use sigchain_pop to restore whoever was before you in the stack.
