Bug 440259
Cause: QN-ItQ
- Evidence: "User::match calls Bugzilla::User::new in a loop instead of using new_from_list, which could mean 1000 SQL calls, one right after another, instead of just one", comment 1
Fix: CQ
- Evidence: In the patch, changed from calling Bugzilla::User::new in a loop to just one call of Bugzilla::User->new_from_list
Interesting Finding: Proposed Patch is DBMS-Dependent
- Evidence: "I have to back out this patch. PostgreSQL complains that we ORDER BY login_name despite we don't list login_name in SELECT DISTINCT.", comment 13
