What is your MySQLdb version?

import MySQLdb
MySQLdb.__version__

[ivanovsuper@…]

MySQLdb 1.2.2 Apache 2.2.15 MySQL 5.1.46 Python 2.6.5 Subversion 1.6.6 It's new installation. Used most recent versions. Trac works ok.

[ivanovsuper@…]

Replying to ivanovsuper@…:

MySQLdb 1.2.2

just installed MySQLdb 1.2.3c1. warning message from above disapeared, but Windows Error? still persist.

It may be the Trac issue with atomic file renames. Can you turn on debug logging in trac.ini and post the log here?

[ivanovsuper@…]

yes debug log helped. Issue resolved. trac setting for backup_dir was set to `db' and base_url not set. db backup didn't work before upgrade... Well, it's not bitten issue, as always 'hands.sys' :( ps. del this ticket please...
