9033601562 logging: use lazy parameter evaluation in log calls. 2018-09-13 17:41:35 +02:00

e7c5cbb270 caches: don't try to delete keys if there aren't any to delete. 
- This is problematic for REDIS backend.

0d75142ebc cache: fix overwrite of flock timeout, and improve logging. 2018-08-06 23:25:23 +02:00

0946eaebaf caches: use repo.lru based Dict cache. This LRUDict uses Timing Algo to not have to use locking 
for the LRU implementation, this it's safer to use for dogpile. We used it before with beaker, so it's
generally more stable.

b9e6b76da3 caches: reduce timeouts on flock, and provide error output about filename which we cannot lock at. 2018-08-04 16:11:55 +02:00

c218e2a9ea caches: use .refresh() instead of .invalidate() 
- .invalidate() does a delete of cached valued under a key, which means
in previous logic we delete, get_or_create, and compute.
- .refresh() is simply replacing exising key with newly computed values, this
creates less locks, and it's faster.

49f08fd080 caches: store computation time inside context manager as helper. Since the with block is full 
calculation we can use it to calculate the function execution time.

64ee0ddc8f caches: turn off thread scoped caches, and allow .ini override. Thread scoped caches are only usefull for development on using pserve 2018-08-02 18:28:22 +02:00

f1497f5afd caches: new cache context managers. 
- deprecate beaker cache completly
- use new cache decorators from dogpile
- use a proper per cache key invalidation

5e9a2b5c64 caches: use safer method of purging keys from memory dict. During some concurrency tests 
we detected that has_key has a race condition, and catching exception is safer.

e9e73ec871 caches: use safest possible pickle for cache backends. 
- If this crashes we end up in fatal non-recoverable state.

6e45dc9605 caches: introduce new conditional cache function. 2018-07-14 18:17:02 +02:00

ec504c9907 caches: use delete_multi for clearing out cache keys. 
- This is a safer and more efficient way of purging many keys.
- For file based cache it only opens the DB once

f4b8149962 caches: allow debug of max_size reached by the MemoryLRU cache. 2018-07-13 17:29:36 +02:00

7d7d6741bb caches: added logging for dogpile configuration. 2018-07-13 13:06:04 +02:00

0e05d6dd64 caches: use a faster LRUDict implementation for LRUMemoryCache 2018-07-12 17:48:12 +02:00

a19d4b732a caches: use a gevent compatible file-lock mechanism. 
- because of gevent we can run into a deadlock situation and worker freeze because of
each of the workers will try to aquire a lock.
- This should help with the issue and gevent.

a48ab8a32d caches: don't use beaker for file caches anymore 2018-07-06 12:55:13 +02:00

ddc445856e caches: rewrite of auth/permission caches to dogpile. 2018-07-05 20:14:33 +02:00
