Attached patch Patch (obsolete) (deleted) — Splinter Review
Before the review, I need some feedback. Why savePing is saving pings synchronously? Is that needed?

Comment on attachment 712156 [details] [diff] [review] Patch Review of attachment 712156 [details] [diff] [review]: ----------------------------------------------------------------- savePings is saving synchronously for two reasons: 1. The tests require sync saves for various things. 2. We're not 100% certain that async saving will actually write everything to disk at shutdown. (i.e. is it guaranteed that the async disk writing gets done before we call exit()?) I'm pretty certain it does, actually, but nobody's taken the time to do it. So it'd be a matter of fixing the tests to not require sync saves--made significantly easier by TelemetryPing having a proper JS API these days--and then making the shutdown saves not require sync saves. A couple nits on the patch below. ::: toolkit/components/telemetry/TelemetryPing.js @@ +643,5 @@ > hping.add(new Date() - startTime); > > if (success) { > + this.saveFileForPing(ping).then(function(file) { > + OS.File.remove(file.path); The old code's remove call could throw; if OS.File.remove doesn't throw when the file doesn't exist, fine.

Given the recent work on cleaning up Telemetry, the patch is certainly completely bitrotten. I will try and rescue that patch once bug 913070 has landed.
I completely forgot about this bug, once that bug lands, I could try and rework on this.

It was used to trigger a callback after all pings had been loaded from a file but since we are using promises now we don't need it anymore.

Yes, we want to upload that histogram but I didn't just remove the (2) instances of READ_SAVED_PING_SUCCESS, I moved them to a single location: addToPendingPings: testLoadHistograms() -> loadHistograms() -> addToPendingPings() -> histogram.add() loadSavedPing() -> loadHistograms() -> addToPendingPings() -> histogram.add() where histogram is Telemetry.getHistogramById("READ_SAVED_PING_SUCCESS"). Instead of passing a callback through all those functions, we just increment that particular histogram directly in addToPendingPings.
