User:Samtar/Why isn't ExternalLinksChange working
Appearance
ExternalLinksChange (an EventLogging schema) isn't working as expected
Bug
Expected behaviour
- Add an external link to any page on test.wikipedia
- Wait up to 1 hour
- Run a query on stat1003 and the change is logged
Real behaviour
- Add an external link to any page on test.wikipedia
- Wait up to 1 hour
- Run a query on stat1003 and the change is sometimes logged
- Wait longer
- Run a query on stat1003 and the change might be there
- Wait even longer
- Run a query on stat1003 and the change still isn't there
- Give up and conclude it's been missed (probably?)
What have we tried?
- Making the change to articlespace on test.wikipedia - still randomly misses log entries
- Adding a link which gets logged in the spam blacklist on test.wikipedia - blacklist logs, still randomly misses
Where should we debug?
- Beta cluster would be good as we can
tail
the log and see what's going on - we should enable the schema there and get sudo (relevant) - Not to be used as a development playground, but will be useful in later debugging - Labs project instance - asking -labs if this is a suitable use of an instance - Currently setting up
- Local MW install via vagrant - Should probably do this anyway..
