From: Paul Eggert <eggert <at> cs.ucla.edu> To: Emacs bug reports and feature requests <bug-gnu-emacs <at> gnu.org> Subject: erc-join-tests runs "forever" on Solaris 10 Date: Mon, 14 Jul 2025 08:16:32 -0700
This is with current Savannah master. I haven't tested on Solaris for a
while so I don't know when it started happening.
To reproduce the problem, build Emacs and run "make check". It loops
seemingly forever. The culprit can be found via:
cd test
make check LOGFILES=lisp/erc/erc-join-tests.log
This ran for about 12 hours before I killed it. Emacs is CPU bound.
"truss" reports a seemingly infinite sequence of syscalls containing the
following pattern, repeated indefinitely:
...
lwp_sigmask(SIG_SETMASK, 0x00000002, 0x00000000) = 0xFFBFFEFF [0x0000FFFF]
lwp_sigmask(SIG_SETMASK, 0x00000000, 0x00000000) = 0xFFBFFEFF [0x0000FFFF]
pollsys(0xFFBFE278, 2, 0xFFBFE5D8, 0x00000000) = 1
lwp_sigmask(SIG_SETMASK, 0x00000002, 0x00000000) = 0xFFBFFEFF [0x0000FFFF]
lwp_sigmask(SIG_SETMASK, 0x00000000, 0x00000000) = 0xFFBFFEFF [0x0000FFFF]
read(25, 0x040AB840, 65536) = 0
timer_settime(0, 1, 0xFFBFE4B8, 0x00000000) = 0
alarm(0) = 0
timer_settime(0, 1, 0xFFBFE438, 0x00000000) = 0
lwp_sigmask(SIG_SETMASK, 0x00000002, 0x00000000) = 0xFFBFFEFF [0x0000FFFF]
lwp_sigmask(SIG_SETMASK, 0x00000000, 0x00000000) = 0xFFBFFEFF [0x0000FFFF]
pollsys(0xFFBFE278, 1, 0xFFBFE5D8, 0x00000000) = 1
lwp_sigmask(SIG_SETMASK, 0x00000002, 0x00000000) = 0xFFBFFEFF [0x0000FFFF]
lwp_sigmask(SIG_SETMASK, 0x00000000, 0x00000000) = 0xFFBFFEFF [0x0000FFFF]
...
The file lisp/erc/erc-join-tests.log looks like this:

The tests in that file have remained unchanged since they were created four years ago. Unfortunately, they were never updated to use the newer fixtures and helpers ERC now uses for mocking connections more responsibly. FWIW, I couldn't yet manage to reproduce the error (https://0x0.st/8dzt.png), though it's quite possible I didn't build Emacs correctly. In any case, I'll at least try to ensure those tests fail fast in the future instead of running forever. For now, I've just arranged to skip the failing one.
