Glance Image Cache Invalid Cache Entry and Stalled Image cleaner
|
2011-07-22 00:53:43 -05:00
|
|
|
|
|
|
|
This is meant to be run as a periodic task from cron.
|
|
|
|
|
|
|
|
If something goes wrong while we're caching an image (for example the fetch
|
|
|
|
times out, or an exception is raised), we create an 'invalid' entry. These
|
|
|
|
entires are left around for debugging purposes. However, after some period of
|
2011-10-21 16:10:32 -04:00
|
|
|
time, we want to clean these up.

|
|
|
|
2011-10-21 16:10:32 -04:00
|
|
|
Also, if an incomplete image hangs around past the image_cache_stall_time
|
2011-07-22 17:20:59 -05:00
|
|
|
period, we automatically sweep it up.
