1280213 - Reprocess crashes with missing Win64 system symbols

Status: RESOLVED FIXED

Since fixing bug 1140937 + bug 1140358 we now have symbols for Win64 system libraries that we were missing for a long time. We should reprocess some of the crashes that have bad signatures due to missing these symbols. I don't have an exhaustive list, but these two queries will pick up a lot of them:

https://crash-stats.mozilla.com/search/?signature=~ntdll&_facets=signature&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#facet-signature
https://crash-stats.mozilla.com/search/?signature=~user32.dll&_facets=signature&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#facet-signature

That's 659 + 2,861 crashes. You could use a SuperSearch API pagination technique to get a list of UUIDs and then push that to https://crash-stats.mozilla.com/api/Reprocessing/
I can help with that.

Exactly 1,971 crashes have now been sent in for reprocessing. Not sure how long it'll take to process through. 

But in an hour or so, let's spot check a random few and verify. Hint; I hope you can do that Ted. I only know to look at the Processor Notes to see that it actually got reprocessed.

Note-to-self: See ~/dev/MOZILLA/SOCORRO/reprocess_some_crashes/1280213.py and ~/dev/MOZILLA/SOCORRO/reprocess_some_crashes/reprocess-1280213.py

Basically if the signature no longer contains ntdll.dll or user32.dll they should be fine. I won't get to look at this till Monday, but I'll leave myself a TODO if you don't have time to check before then.

This is what happened in Datadog when I sent those crashes in.
