Message #02735
[Merge] lp:~wgrant/launchpad/checkwatches-will-you-be-quiet-please into lp:launchpad
William Grant has proposed merging lp:~wgrant/launchpad/checkwatches-will-you-be-quiet-please into lp:launchpad.
Requested reviews:
Launchpad code reviewers (launchpad-reviewers)
Related bugs:
#719288 checkwatches saves OOPS reports for occurrences that don't need them
https://bugs.launchpad.net/bugs/719288
For more details, see:
https://code.launchpad.net/~wgrant/launchpad/checkwatches-will-you-be-quiet-please/+merge/50892
This branch suppresses lots of checkwatches OOPSes. In particular, InvalidBugId, BugNotFound, PrivateRemoteBug, UnknownRemoteStatus, and UnknownRemoteImportance are now logged at INFO instead of as OOPSes and at WARNING.
The first three show up already in the UI as BugWatchActivity entries. The OOPS had no further useful information. There is some argument that UnknownRemote(Status|Importance) deserve OOPSes, but they will be easily greppable from logs, the Unknown value will be obvious to anyone looking at an affected bug, and they only tend to get fixed when users complain anyway.
InvalidBugId, BugNotFound, and PrivateRemoteBug were easily fixed by changing the logging in their exception handler.
RemoteBugUpdater had a wrapper around status conversion which logged the exception nicely, but there was no similar thing for importance. I turned the OOPS into an INFO log entry, and generalised it to work for importance too. _convertRemoteStatus was tested in a doctest where the log level was WARNING, making it hard to check that it logged correctly. So I replaced it with unit tests and extended them to _convertRemoteImportance.
