Title:
  python-mysqldb silently drops exceptions on deadlocks

Status in MySQLdb:
  Invalid
Status in python-mysqldb package in Ubuntu:
  Invalid
Status in python-mysqldb package in Debian:
  Invalid

Bug description:
  Binary package hint: python-mysqldb

  There is a missing check in _mysql.c _mysql_ResultObject_Initialize,
  where a failed SELECT that ends in a deadlock, returns a NULL from
  mysql_store result, but according to
  http://dev.mysql.com/doc/refman/5.0/en/null-mysql-store-result.html,
  you have to check errno or num_fields afterwards.

  Not doing this, causes exceptions to be silently dropped.

  Here's a similar bugreport
  http://sourceforge.net/tracker/?func=detail&aid=2776267&group_id=22307&atid=374932

  Attached is a patch that fixes the problem in _mysql.c. It was made
  against 1.2.3, but applies to 1.2.2 with some fuzz.

  Patch has also been submitted to python-mysqldb at sourceforge
  (http://sourceforge.net/tracker/?func=detail&aid=3008217&group_id=22307&atid=374934)
  and for debian (http://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=584260)
