Description (last modified by )
Reported on sage-devel:
I ran ./sage -t -long -force_lib "devel/sage/sage/libs/fplll/fplll.pyx" 1000 times in serial [1] with a 64-bit 4.6.rc0 built on OS X 10.6 (bsd.math). All but one of the runs pass. The failure: Run 766 of 1000 Detected SAGE64 flag Building Sage on OS X in 64-bit mode sage -t -long -force_lib "devel/sage/sage/libs/fplll/fplll.pyx" ********************************************************************** File "/Users/buildbot/build/sage/bsd-2/bsd_64_full/build/sage-4.6.0pre0/devel/sa ge/sage/libs/fplll/fplll.pyx", line 853: sage: L.echelon_form() == A.echelon_form() Expected: True Got: False
The error also occurs with a 32-bit build on bsd.math (OS X 10.6, 5 out of 1000 runs) and on sage.math (64-bit Ubuntu 8.04.4 LTS, 6 of 1000 runs).
David Kirkby does not get any incorrect results on OpenSolaris 06/2009 after more than 15000 runs with 4.6.rc0 and more than 16000 with 4.6.1.alpha0. He had a total of 31748 passes. However, he did experience 109 doctest failures which are likely to be result of doctesting two copies of Sage simultaneously, as these were using the same directory for temporary files ($HOME/.sage/tmp
). His errors were like this:
Run 442 of 100000 sage -t -long -force_lib "devel/sage/sage/libs/fplll/fplll.pyx" python: can't open file '/export/home/drkirkby/.sage//tmp/fplll.py': [Errno 2] No such file or directory [0.2 s]
and never due to False being return instead of True.
