New submission from Ned Deily <[email protected]>:
After upgrading my first macOS system to the newly released macOS 10.14.4
update, attempts to run the Python test suite via regrtest fail:
$ /usr/local/bin/python3.7 -m test -uall -j3 -w
Traceback (most recent call last):

resource.setrlimit(resource.RLIMIT_STACK, (newsoft, hard))
ValueError: current limit exceeds maximum limit
The error is during regrtest initialization when it is trying to increase the
process stack size to avoid previously seen problems when running tests. This
code has been unchanged for a long time.
Stepping through the code in the REPL on 10.14.4:
>>> import resource
>>> resource.getrlimit(resource.RLIMIT_STACK)
(8388608, 67104768)
>>> soft, hard = resource.getrlimit(resource.RLIMIT_STACK)
>>> newsoft = min(hard, max(soft, 1024*2048))
>>> newsoft
8388608
>>> resource.setrlimit(resource.RLIMIT_STACK, (newsoft, hard))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: current limit exceeds maximum limit
The same code run on a macOS system still running 10.14.3 gives the same values
from getrlimit but does not fail when calling setrlimit.
I will investigate further tomorrow; if this is a general problem with macOS
10.14.4, we'll need to provide a workaround and possibly open an incident
report with Apple.
