Test needed.

Description

Include session id with last exec event

[akleshchev]

Startup crashes have no session ids, how should that case be treated? Just a locally generated UUID? Or should be there some different identifier for such crashes? Like packing session id and viewer's 'instance' id.

[akleshchev]

At review, should I also include session id in bugsplat's attributes?

[nat-goodspeed]

Sounds like a good idea, to correlate BugSplat crashes with our own crash information.

[akleshchev]

On practice turned out to be a bit complicated. Windows part is trivial, but Mac needs to pull session id from dump files (and probably is going to be as unreliable as Mac's logs are), will make a separate ticket.

[akleshchev]

Server side confirmed that they are getting last_exec_session_id, just needs filters now.

Given the above comment, this will be considered to have passed viewer QA if no obvious issues are found in the next round of testing.

[Dan-Linden]

Nothing further to test on the viewer side. Passing QA on this.
