From 926cd469c849f974c1d76be8682a8b27e10e05ad Mon Sep 17 00:00:00 2001 From: Diego Russo Date: Fri, 7 Mar 2025 21:10:02 +0000 Subject: [PATCH] gh-130917: update timer and workload in test_signal (GH-130918) The workload to advance the virtual timeout is too lightweight for some platforms. As result the test goes in timeout as it never reaches the end of the timer. By having a heavier workload, the virtual timer advances rapidly and the SIGVTALRM is sent before the timeout. (cherry picked from commit 78790811989ab47319e2ee725e0c435b3cdd21ab) Co-authored-by: Diego Russo --- Lib/test/test_signal.py | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/Lib/test/test_signal.py b/Lib/test/test_signal.py index 08f18a99f8d0e3..e69b4452f53f94 100644 --- a/Lib/test/test_signal.py +++ b/Lib/test/test_signal.py @@ -840,11 +840,11 @@ def test_itimer_real(self): def test_itimer_virtual(self): self.itimer = signal.ITIMER_VIRTUAL signal.signal(signal.SIGVTALRM, self.sig_vtalrm) - signal.setitimer(self.itimer, 0.3, 0.2) + signal.setitimer(self.itimer, 0.001, 0.001) for _ in support.busy_retry(support.LONG_TIMEOUT): # use up some virtual time by doing real work - _ = pow(12345, 67890, 10000019) + _ = sum(i * i for i in range(10**5)) if signal.getitimer(self.itimer) == (0.0, 0.0): # sig_vtalrm handler stopped this itimer break @@ -861,7 +861,7 @@ def test_itimer_prof(self): for _ in support.busy_retry(support.LONG_TIMEOUT): # do some work - _ = pow(12345, 67890, 10000019) + _ = sum(i * i for i in range(10**5)) if signal.getitimer(self.itimer) == (0.0, 0.0): # sig_prof handler stopped this itimer break
