Bug 69303 – watchlist: Don't add the same message to a bug more than once.

• Component: Tools / Tests
• Status: RESOLVED FIXED

[David Levin]

Right now the watchlist will run once per attachment and that may result in spammy messages.

One approach is to look at who is CCed on the bug already.  You can also scan the comments for whatever message you would spam.

I think we're fine on the cc list as I tried it out :) and I adding someone to the cc list who is already there seems to be a no-op.

I only care about the text but since I need to check the text (which requires fetching the bug), I might as check the cc as well to avoid making the server do unnecessary work.

Yeah, the issue of when bug ID are numbers and when they are strings is tricky.  We didn't realize it would be a problem until it was too late.  We're more careful in new objects.

Module private functions start with _ by convention.  This seems like it should be a method on bug though.

You can do this more easily with the filter function.

Fixed all (and added a simple unit test for the new bug method).
