join_conds in SQL select wrapper seem broken in Postgress
Closed, ResolvedPublic


Author: michaelcirello2

Special pages (BrokenRedirects, etc) are generating invalid SQL. It seems the 'from' and 'join' clauses are not being constructed correctly. This is with Postgres as the db if it matters.

Example query generated from brokenredirects below. Note FROM "p2". This obviously doesn't exist and was supposed to be part of a join that is not included at all.

SELECT /* BrokenRedirectsPage::reallyDoQuery Mike */

p1.page_namespace AS namespace,
p1.page_title AS title,
p1.page_title AS VALUE,

FROM "p2"
WHERE (rd_namespace >= 0) AND

(rd_interwiki IS NULL OR rd_interwiki = '') AND
(p2.page_namespace IS NULL)

ORDER BY rd_namespace,rd_title,rd_from

Version: 1.22.2
Severity: normal

Yep it does. (How SQL is constructed is different for every db backend)

Testing this locally on 1.22.2 and using mysql seems to work fine. Highly suspect its an issue with the postgres wrapper class

Sounds like the problem from bug 60031

Fixed in the meantime, should be part of 1.22.3 (Looks like bug 60531)
