tests: robustify attach-p-cmd.test against buggy kernels From time to time various kernels, old and new, just go nuts and fail attach-p-cmd.test with the following diagnostics: 12345 --- SIGALRM {si_signo=SIGALRM, si_code=SI_KERNEL} --- -12345 chdir("attach-p-cmd.test -p") = -1 ENOENT (No such file or directory) +12345 syscall_4294967295(0xffe60934, 0x1c0, 0xffe60934, 0x1, 0xffe609b4, 0xffe60a58) = -1 (errno 38) +12345 chdir("attach-p-cmd.test -p") = -1 ENOSYS (Function not implemented) Let's workaround this kernel madness by rewriting the test without use of SIGALRM. * tests/attach-p-cmd.h: New file. * tests/Makefile.am (EXTRA_DIST): Add attach-p-cmd.h. * tests/attach-p-cmd-cmd.c: Include "attach-p-cmd.h". (write_pidfile, wait_for_peer_invocation): New functions. (main): Use them. * tests/attach-p-cmd-p.c: Include <time.h> and "attach-p-cmd.h". (wait_for_peer_invocation, wait_for_peer_termination): New functions. (main): Use them. Do not raise SIGALRM, use nanosleep after peer termination. 2017-12-03 03:25:43 +03:00			`static const char lockdir[] = "attach-p-cmd.test-lock";`
