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.
