I just now tested with 3.1.1's test suite and that fails in the same way.
test_math.py is now skipped.
How is it acceptable to just not run the part of the test suite that's failing? Does anyone else think that's a bit ridiculous? This bug is due to bug 264335 -- one with a patch to fix it. But no one on toolchain@ seems interested in doing anything with it. This obviously isn't a python bug, don't disable the test_math.py. That's just silly. Reopening so that someone sees this.
Ran test suite: no failures with patched glibc. Please reenable test and close this bug.
(In reply to comment #3) > How is it acceptable to just not run the part of the test suite that's > failing? Only test_math.py was temporarily disabled. Disabling particular parts of given test file would require creating conditionally applied patch and needless bumping whole patchsets. test_pow.py has been disabled for over 15 months. Anyway there is over 360 other test files. There is nothing in this bug which would be interesting for QA, but maybe they like receiving more e-mails...
(In reply to comment #0 and comment #1) The reporter: Could you confirm that all tests from test_math.py and test_pow.py pass after deletion of the following line from the 2.6.2-r1 and 3.1.1 ebuilds?: [[ ${ARCH} == "alpha" ]] && skip_tests+=" math pow"
I noticed that sys-libs/glibc-2.9_p20081201-r3 isn't stable yet on alpha. Do you prefer that tests of dev-lang/python fail with stable versions of sys-libs/glibc for some time or do you prefer to quickly stabilize sys-libs/glibc-2.9_p20081201-r3 on alpha?
We're going to quickly stabilize -r3, as its main difference between -r2 is a regression fix for the stuff that caused the math/pow tests to fail. I've filed a stabilization bug for -r3 on alpha, bug 283188.
After upgrading glibc to the version with the fixed, I tried the most recent versions of python (i.e. 3.1.1, 2.6.2-r2, 2.5.4-r3, 2.4.6) and all of them now pass both test_math and test_pow, so the special-casing for alpha on these ebuilds can be removed (the patched glibc will go to stable today).
test_math.py and test_pow.py have been reenabled on alpha.
