"Updating Launchpad bug reference" comment is redundant

[Matthew Paul Thomas]

In <http://gobby.0x539.de/trac/ticket/271>, the last action is the Launchpad Trac plug-in updating the Launchpad bug reference. This is followed by a comment: "Updating Launchpad bug reference". This comment has then been imported into <http://launchpad.net/bugs/70653>, where it's not relevant to anyone using Launchpad.

If the Launchpad Trac plug-in just changed the bug reference without an extra comment, it would still be obvious in Trac (because it would still say "launchpad_bug set to 70653"), but there would be no redundant comment imported into Launchpad.

Unfortunately, that's the way that bug metadata updates are handled in
Trac; every transition becomes a comment; there's no way to turn this
off, AFAICT.

The only way to avoid these comments appearing in Launchpad, then, is
to explicitly filter them out. This shouldn't be too hard to do since
the user who authored the comment should be the 'launchpad' user
(unless someone's done some customisation of the plugin, in which case
all bets are off).

However, this behaviour is part of the cause of bug 296789.

[Matthew Paul Thomas (mpt)]

<http://gobby.0x539.de/trac/ticket/272> and <http://gobby.0x539.de/trac/ticket/273>, to pick just the first two examples I looked at, include status changes that seem not to be accompanied by comments. In the former, "* type changed from defect to enhancement". And in the latter, "* status changed from new to closed * resolution set to wontfix".

Are these lines actually injected as comments in Trac markup, so it's impossible to distinguish them from real comments?

Herb has now deleted the offending comments and watches from this bug. Hurrah.
