Total duration: 29 min 42 sec

Version-Release number of selected component (if applicable):
python3-3.6.4-9.fc28

How reproducible:


Steps to Reproduce:
1. Enable test_gdb in python3 spec file (if it's disabled)
2. Build python3 in Koji for x86_64 architecture

Comment 1 Tomas Orsava 2018-02-05 10:43:25 UTC
This issue does not appear to be similar to the reported test_gdb failure on PPC: bz#1132488.

Comment 2 Fedora End Of Life 2018-02-20 15:34:05 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.

Comment 3 Iryna Shcherbina 2018-02-21 16:37:40 UTC
test_gdb does not fail with Python 3.7 on x86_64, but so far I do not see what fixed it. Also I can not reproduce this when running the tests on Fedora Rawhide from cpython source on v3.6.4 tag.

This happens though in mock and Koji, still investigating.

Comment 4 Iryna Shcherbina 2018-02-26 20:38:06 UTC
The failures can be reproduced on Fedora 28 from source:

./configure --with-pydebug
make 'EXTRA_CFLAGS=-mcet -fcf-protection -O0'
make test TESTOPTS='-v test_gdb'


The test test_gdb fails only in debug build, and only if built with control flow protection [0] flags `-mcet -fcf-protection` AND optimization `-O0`.

Comment 5 Charalampos Stratakis 2018-02-26 23:05:52 UTC
This issue should be reported upstream. I'll see if I can bisect the fix.

Comment 6 Jan Kurik 2018-08-14 10:16:12 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 29 development cycle.
Changing version to '29'.

Comment 7 Petr Viktorin (pviktori) 2018-09-24 12:45:09 UTC
Should be fixed in the next upstream release. We should re-enable the tests then.

Comment 8 Victor Stinner 2018-11-19 11:00:43 UTC
test_gdb is currently broken on Fedora 29 because of a gdb bug: bug #1639242 ( gdb fails to read debug symbols).

Comment 9 Victor Stinner 2019-01-07 13:41:29 UTC
It's a bug in gdb: see bz#1638798.

Comment 10 Victor Stinner 2019-01-21 21:24:07 UTC
gdb has been fixed in Fedora Rawhide: bz#1638798.

Comment 11 Victor Stinner 2019-01-24 10:51:47 UTC
The "py-bt" gdb command works as expected on python3 (python3-3.7.2-1.fc29.x86_64).

test_gdb pass on Python 3.6.8 and 3.7.2 (at least when compiled manually using "./configure && make").

Since this issue has been reported, I fixed multiple test_gdb bugs upstreams and fixes are part of 3.6.8 and 3.7.2 releases.

> It's a bug in gdb: see bz#1638798.
> gdb has been fixed in Fedora Rawhide: bz#1638798.

I'm sorry, I was confused. Fedora 29 and Rawhide don't use the same gdb version. gdb in Fedora 29 wasn't affected by the gdb bug of Rawhide.

Comment 12 Miro HronĨok 2019-01-24 13:02:57 UTC
we need to unskip it before we close this.

Comment 13 Victor Stinner 2019-02-18 12:57:50 UTC
> we need to unskip it before we close this.

Alright. I planned to unskip the test after closing the issue, but I'm fine with keeping the BZ issue open until the package is updated.

I wrote https://src.fedoraproject.org/rpms/python3/pull-request/89 but I have multiple issues to get this change merged... test_gdb still fails on arm and s390x:
* armv7hl: https://bugzilla.redhat.com/show_bug.cgi?id=1196181
* s390x: https://bugzilla.redhat.com/show_bug.cgi?id=1678277

I plan to at least reenable test_gdb on x86-64 (in practice: reenable test_gdb on all archs except arm and s390x).

Comment 14 Victor Stinner 2019-02-19 16:49:24 UTC
I created https://src.fedoraproject.org/rpms/python3/pull-request/93 to reenable test_gdb.

Comment 15 Victor Stinner 2019-02-21 11:29:16 UTC
https://src.fedoraproject.org/rpms/python3/pull-request/93 has been merged into the f29 branch:
https://src.fedoraproject.org/rpms/python3/c/4bcbcff606bcac5cc7cbccf1192a01f2f89b899c?branch=f29

Since the change only impacts the build of the package, the package release is not incremented. I close the issue.
