Fix #3046.

  • Add a test specific cache file for logStorage so that tests don't fail because of stuff in the cache from other tests. Thanks to @ryanwilson for the suggestion and helper file implementation!
  • Set up the self.mockTimeFetcher currentTimestampInSeconds stub before the mock is passed to other functions.
  • Stop calling scheduleNextSend in the initializer since the first zero-delayed log can happen logs to happen to soon.
  • Remove early exit from scheduleNextSend since it can cause logs to get dropped if the first zero-length log is scheduled, the next real log gets scheduled, but the log has already been dropped because of no packets available.
  • Multiple spelling and wording fixes.

Will want to hear back from @christibbs about this one. We may want to do this in case there are actually pending logs that are written to disk?

Trying out an approach where we only call this if there are pending logs to be sent.

Don't we want to keep this, checking if _nextSendScheduled is already set? I noticed in the log you mentioned it could cause an issue, but is the issue because of this check AND the scheduleNextSend in the init or just the one?

I added this check back, but I'm not sure what _nextSendScheduled = YES in the else block was doing.. it's already being set to YES at the end of the method. I removed the else block.

I think this could still cause problems if you want to change waitTime. The new waitTime will get ignored for the next scheduled send. Perhaps that's ok?

I think that should be fine. The timing of sending logs doesn't need to be precise in this case.

LGTM but want to confirm that the scheduleNextSend logic change is okay and is tested with a sample app.

@ryanwilson I'm testing out an approach where it only schedules the next send on init if there are logs to be sent at that time.
