408729 - Collect "time since open" stat

Status: RESOLVED FIXED

(Toolkit :: Crash Reporting, defect, P2)

Description

[Samuel Sidler (old account; do not CC)]

When should collect a "time since open" stat.

Rationale: 

Collecting the time since last crash is fine for determining the "mean time before crash" but it doesn't help us track if a crash is on startup and see how many startup crashes there are. We can use the "time since [Firefox] open[ed]" to determine if there are a lot of startup crashes and to see how long users regularly keep their browsers open before crashing.

Would really like to get this so we can get a better idea from release to release how we are doing on actual stability

Really simple patch to add a StartupTime field to the crash report.  We can easily calculate time since start by subtracting this from CrashTime on the server.  Obviously we'll need to make a server-side change (and probably a db change) to actually collect this info.

Checked in.  Filed http://code.google.com/p/socorro/issues/detail?id=114 for the server-side component to this.

Backed out.  This doesn't compile right on Linux/mac.  :-(

Right, tested this on Linux and Win32, should work fine everywhere.
