This is probably not a correct assumption (or likely intended), but causes git to no longer build on NonStop x86 and ia64 as of 2.32.0-rc0. I am not suggesting undoing this, but amending to make the change more sensitive to a lack of pthread support. pthread_sigmask() showed up as an undefined external: **** ERROR **** [1210]: libgit.a(ipc-unix-socket.o): In function `thread_block_sigpipe': ipc-unix-socket.o(.text+0xb87): unresolved reference to pthread_sigmask. On NonStop, pthread_sigmask is defined in -lput or -lspt, which are not used in our build ? and would cause a bunch of other issues if referenced. The build does define NO_PTHREADS. A simple, but probably wrong fix to get the build to work is: diff --git a/compat/simple-ipc/ipc-unix-socket.c b/compat/simple-ipc/ipc-unix-socket.c index 38689b278d..07b2c407c1 100644 --- a/compat/simple-ipc/ipc-unix-socket.c +++ b/compat/simple-ipc/ipc-unix-socket.c @@ -535,7 +535,9 @@ static void thread_block_sigpipe(sigset_t *old_set) sigaddset(&new_set, SIGPIPE); sigemptyset(old_set); +#ifndef NO_PTHREADS pthread_sigmask(SIG_BLOCK, &new_set, old_set); +#endif } But I suspect that this will not perform the desired action associated with blocking the signal, although since we are not in a threading situation, that might be fine. Thoughts?
