From 6d81a2136d61cb787e7bd7fc26a7ba2a363d8c40 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Fri, 20 May 2016 13:15:55 +0200 Subject: [PATCH] regrtest doesn't ignore -j1 anymore * regrtest now uses subprocesses when the -j1 command line option is used: each test file runs in a fresh child process. Before, the -j1 option was ignored. * Tools/buildbot/test.bat script now uses -j1 by default to run each test file in fresh child process. --- Lib/test/libregrtest/cmdline.py | 2 -- Misc/NEWS | 10 ++++++++++ Tools/buildbot/test.bat | 2 +- 3 files changed, 11 insertions(+), 3 deletions(-) diff --git a/Lib/test/libregrtest/cmdline.py b/Lib/test/libregrtest/cmdline.py index c7e990db1f6..de09a0122ab 100644 --- a/Lib/test/libregrtest/cmdline.py +++ b/Lib/test/libregrtest/cmdline.py @@ -318,8 +318,6 @@ def _parse_args(args, **kwargs): if ns.use_mp <= 0: # Use all cores + extras for tests that like to sleep ns.use_mp = 2 + (os.cpu_count() or 1) - if ns.use_mp == 1: - ns.use_mp = None if ns.use: for a in ns.use: for r in a: diff --git a/Misc/NEWS b/Misc/NEWS index 5dccc5c5ba7..628426ba56b 100644 --- a/Misc/NEWS +++ b/Misc/NEWS @@ -22,6 +22,16 @@ Library - Issue #27056: Optimize pickle.load() and pickle.loads(), up to 10% faster to deserialize a lot of small objects. +Tests +----- + +- Issue #25285: regrtest now uses subprocesses when the -j1 command line option + is used: each test file runs in a fresh child process.
