Detected Queue End as 20 Minutes Before the Hour

(1/2) > >>

n9xcr:
I saw this happen once last week and wrote it off as an anomaly, but it JUST happened again. Scheduler looked at the queue which was going to end at the TOTH and thought it was going to end at 20 minutes sooner. It then scheduled an additional 20 minutes of tracks which would have delayed the legal ID until 20 after the hour.

Here's an excerpt from the log that shows the end of scheduling the 8:00 hour and beginning of the 9:00 hour.

Jay Lichtenauer:
Versions?

Only sometimes?

The reason I ask this is because starting in version 2011.12.1, the location of where the queue end point is saved is changed and you must run at least 2011.12.1 of both DJ and Scheduler.

n9xcr:
Yes, only sometimes. I wish I would have made a note of the last time I saw it happen. I *want* to say it was the same time of day.  :D Anyways...

Scheduler - 2011.12.2
DJ - Version 2011.12.1

Jay Lichtenauer:
There are already a lot of provisions to make sure this can't happen such as retrying the file 20 times over 10 seconds if the queue end time was read as 0. Your log shows it determining the queue end point inside a second so I think The only way I can see this happening is the file system has reported the ~/Library/Preferences/Radiologik/Queue End file doesn't exist and with that it will exit right away with a zero in queue. So with that as the theory I will make a retry loop on seeing if the file exists and if it fails it should just consider queue end time to be the start time like the other provisions do.

I did a search for this error occurring on two stations over a long period of several weeks and it always reads the queue from DJ correctly. But if it this is happening to one person, it will almost certainly show for someone else.

Jay Lichtenauer:
I've added more provisioning to this build. I can't test against a failure here so please give it a try:
