CirrusSearch index incompleteness problem
by Aran 28 Jan '17

28 Jan '17

Hello, I'm managing some mediawiki 1.27.1's running CirrusSearch 0.2 with Elasticsearch 1.7.5. I been noticing that there are often search results missing so I started running the forceSearchIndex.php script each night on a cron job. But I'm still finding results missing. Today I re-ran the script manually and then found that one of the missing results showed up and that the result count for that term had increased from 18 to 23. I ran the script again and it increased more to 37. I ran more times but the result count did not increase any more. The commands I've been doing are: forceSearchIndex.php --skipLinks --indexOnSkip forceSearchIndex.php --skipParse Is this the correct way to do a full index rebuild? is there some parameter that can ensure that no pages get missed? Thanks, Aran

Reverted to 1.28.0-wmf.8 once more.
by Mukunda Modell 27 Jan '17

27 Jan '17

The deployment of MediaWiki 1.29.0-wmf.9 is currently blocked and all wikis have been reverted to wmf.8. This latest revert is due to excessive warnings which appeared in logs immediately after deploying to group2. The warnings all read as follows: Warning: Empty regular expression in /srv/mediawiki/php-1.29.0-wmf.9/includes/parser/DateFormatter.php on line 200 This issue is tracked in https://phabricator.wikimedia.org/T156364 and currently blocks further deployments. More background: A similar flood of log spam occurred after deploying the branch to group1, however, the problem subsided after a while and did not reappear until Thursday's deployment. There have been recent changes to DateFormatter.php, however, the changes do not appear to be the direct culprit. In fact, after rolling back the changes, a different message appears in the log, however, with less frequency than the line 200 error. Several engineers have looked at this issue but so far we have not isolated the root cause. Additional eyes on this issue would be welcomed and further discussion should be directed to Phabricator. In the interest of keeping everyone in the loop, I will follow up in this thread if/when there is a resolution. Regards, Mukunda --- Mukunda Modell Wikimedia Release Engineering

+2 request for yurik in mediawiki and maps-dev
by Legoktm 26 Jan '17

26 Jan '17

Hi, After speaking with Yurik, I've filed <https://phabricator.wikimedia.org/T156219> on his behalf to restore his membership in the mediawiki and maps-dev groups. I would appreciate guidance in whether these rights can be summarily granted since he used to have them, or if it needs to go through the full process. -- Legoktm

Deprecation logging in production
by Erik Bernhardson 26 Jan '17

26 Jan '17

Noticed earlier today, because some code that had been deprecated since 1.21 was removed and starting causing fatals, that we don't log deprecation notices in production. This has now been fixed. Please check logstash for `channel:deprecated` and see if anything you are reposinsible for is using hard-deprecated methods and fix them. Some culprits which have each generated hundreds of messages in the ~5 minutes it's been turned on: Use of SpecialRecentChangesQuery hook (used in FlaggedRevsUIHooks::modifyRecentChangesQuery) was deprecated in MediaWiki 1.23. [Called from SpecialRecentChanges::runMainQueryHook in /srv/mediawiki/php-1.29.0-wmf.8/includes/specials/SpecialRecentchanges.ph Use of wfSetupSession was deprecated in MediaWiki 1.27. [Called from CollectionSession::startSession in /srv/mediawiki/php-1.29.0-wmf.8/extensions/Collection/Collection.session.php at line 38] Use of SpecialWatchlistQuery hook (used in FlaggedRevsUIHooks::modifyChangesListQuery) was deprecated in MediaWiki 1.23. [Called from SpecialWatchlist::runMainQueryHook in /srv/mediawiki/php-1.29.0-wmf.8/includes/specials/SpecialWatchlist.php at line 309] Use of Revision::getText was deprecated in MediaWiki 1.21. [Called from FlaggedRevision::getRevText in /srv/mediawiki/php-1.29.0-wmf.8/extensions/FlaggedRevs/backend/FlaggedRevision.php at line 480] Use of SpecialRecentChangesQuery hook (used in FlaggedRevsUIHooks::modifyRecentChangesQuery) was deprecated in MediaWiki 1.23.
