We have plenty of signatures shown in Xcode but nothing new has trickled into views on crash-stats (1.1 & 1.2)

Stephan hooked Breakpad into Fennec for iOS, and Ted is our Breakpad expert, adding both of them here.

Stephan, any idea what's up there? Is Breakpad not working right in our iOS builds?

Is it possible that reports are simply not being processed or shown? Is there any raw data for submitted reports on crash-stats Kairo?

So I think I see what the issue is here. Now that I have a crash I can reproduce on the App Store build I can see what's going on.

1. When the App Store app crashes, the 'Send Crash' prompt is never shown to the user. Since crash reporting is off by default, there's a very good chance no one has manually turned it on in the settings page which is why we're not seeing any crashes in the app.

2. After turning on crash reporting manually, I was able to crash the app and verify a request was sent to the crash-stats server. It created a new crash as expected: https://crash-stats.mozilla.com/report/index/a76c7635-7aad-4b30-9fc2-389f12151119. However, when I do a query for all crashes in FenneciOS that are marked with the 'release' release channel, nothing shows up.

No, the search shows all submitted crashes that we could process (the only issue could be a systemic corruption of the data that makes the processor fall over, but I would have heard about that from the Socorro team, I think).

Why is it off by default? Sending crashes is on by default on all our other products (with a prompt on every crash for desktop/Android*, and on the first crash for FxOS).

*subject to change based on discussions going on right now

I know before we had to make it opt-in because we didn't have prompt when a crash occurred but now that we have the prompt I feel like that can change to being opt-out.

That would be great, would match our other products.

Just to add some more detail, the report crash dialog is showing but only in cases where there are tabs open with history. Filed https://bugzilla.mozilla.org/show_bug.cgi?id=1226389 to track a fix for that.

Also https://bugzilla.mozilla.org/show_bug.cgi?id=1226391 for the opt-in issue.
