[3.8] bpo-38456: Use /bin/true in test_subprocess#16737
Merged
Conversation
* bpo-38456: Use /bin/true in test_subprocess. Instead of sys.executable, "-c", "pass" or "import sys; sys.exit(0)" use /bin/true when it is available. On a reasonable machine this shaves up to two seconds wall time off the otherwise ~40sec execution on a --with-pydebug build. It should be more notable on many buildbots or overloaded slower I/O systems (CI, etc).. (cherry picked from commit 67b93f8) Co-authored-by: Gregory P. Smith <greg@krypto.org>

Applying this improvement to test_subprocess in 3.8 makes sense, but only after 3.8.0 is out the door. |
