New submission from Felix Yan <felixonm...@archlinux.org>:
In my riscv64 build, test_thousand (test.test_multiprocessing_forkserver.WithProcessesTestBarrier) always hangs on some locking thing, and the compileall part during installation hangs the same way. I am not sure if it's toolchain related or something else, though. Some relevant versions: Linux riscv64-unknown-linux-gnu Python 3.8.4 glibc 2.31 gcc 10.1.0 configure switches: ./configure --prefix=/usr \ --enable-shared \ --with-computed-gotos \ --enable-optimizations \ --with-lto \ --enable-ipv6 \ --with-system-expat \ --with-dbmliborder=gdbm:ndbm \ --with-system-ffi \ --with-system-libmpdec \ --enable-loadable-sqlite-extensions \ --without-ensurepip When Ctrl-C: test_thousand (test.test_multiprocessing_forkserver.WithProcessesTestBarrier) ... ^CProcess Process-1305: Traceback (most recent call last): File "/build/python/src/Python-3.8.4/Lib/multiprocessing/process.py", line 315, in _bootstrap self.run() File "/build/python/src/Python-3.8.4/Lib/multiprocessing/process.py", line 108, in run self._target(*self._args, **self._kwargs) File "/build/python/src/Python-3.8.4/Lib/test/_test_multiprocessing.py", line 1970, in _test_thousand_f barrier.wait() File "/build/python/src/Python-3.8.4/Lib/threading.py", line 610, in wait self._enter() # Block while the barrier drains.
