Bug 666960 – dev-python/mysql-python may need to be rebuilt when upgrading python

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description Dennis Lichtenthäler 2018-09-24 08:04:52 UTC]

When upgrading a stable system from dev-lang/python-2.7.14-r1 to 2.7.15 python scripts that used dev-python/mysql-python crashed with a segfault. Rebuilding mysql-python fixed that.
Should this be done automatically when upgrading python?

Probably related to mysql-connector being installed.

[Comment 2 Dennis Lichtenthäler 2018-09-25 08:35:42 UTC]

dev-db/mysql-connector-c was installed, I didn't rebuild it though.

[Comment 3 Tomáš Mózes 2018-09-25 08:48:28 UTC]

Did you only upgrade python or mysql/mariadb too?

I think we need more specific information about what changed on your system to break this.

I have experienced the same problem after having installed dev-db/mysql-connector-c required by mysql-5.6.40. This was the history of packages installation:

$ qlop -l mysql-python | tail -n1
Sat Jan 13 20:10:15 2018 >>> dev-python/mysql-python-1.2.5-r1

$ qlop -l mysql-connector-c | tail -n1
Mon Sep 17 11:45:05 2018 >>> dev-db/mysql-connector-c-6.1.11-r1

$ qlop -l mysql | tail -n1
Mon Sep 17 11:47:58 2018 >>> dev-db/mysql-5.6.40-r2

$ qlop -l python| tail | tail -n1
Mon Sep 17 11:49:18 2018 >>> dev-lang/python-2.7.15

I got segfaults in python when using mysql-python module, the backtrace was pointing to a problem in mysql-connector-c. After manually emerging mysql-python the problem disappeared.
