Using this as my tracking bug.

[Radar WebKit Bug Importer]

This was duplicated:

[Lucas Forschler]

This bug wasn't duplicated.
Looking at logs of the other two... it appears we called migrate-bugs twice in a row. I'm not sure why.

[Lucas Forschler]

for 183218, here is what I think happened:

Looking at history:
[e-mail]	2018-02-28 11:09:25 PST	CC		[e-mail]
[e-mail]	2018-02-28 11:09:28 PST	Assignee	[e-mail]	[e-mail]
[e-mail]	2018-02-28 11:09:54 PST	Keywords		InRadar

see the importer was CC'd at 11:09:25 , and then another change was made to the bug (at 11:09:28) before the "InRadar" keyword made it back into Bugzilla (11:09:54).

[Lucas Forschler]

the same thing happened to 183249:
[e-mail]	2018-03-01 11:04:10 PST	CC		[e-mail]
[e-mail]	2018-03-01 11:04:19 PST	Assignee	[e-mail]	[e-mail]
[e-mail]	2018-03-01 11:04:38 PST	Keywords		InRadar

[Lucas Forschler]

It looks like there is a race condition. If a bug is modified after CC'ing the importer, but before we get the InRadar keyword, we span another update attempt.

[Lucas Forschler]

I'm not sure the best way to address this. We could consider a 'settle timer', to give bugzilla a chance to catch up before processing again.

I had a feeling it was some kind of race condition. I typically do it that way — CC the importer, then assign the bug to myself.
