Revision: 108300
Author: aaron
Date: 2012-01-07 01:33:23 +0000 (Sat, 07 Jan 2012)
Log Message:
-----------
In FileBackend/FileOp:
* Replaced 'media' portion of container names with the repo name. This makes it
easy for multiple repos to use the same backend without 'wikiId' hacks. Full
container names are now like <wiki>-<repo>-<zone> (or <repo>-<zone> if 'wikiId'
is set to an empty string).
* Restricted isValidContainerName() more in light of Azure portability and
shorted shard suffix.
* Bumped $maxCacheSize to 75 storage paths.
* Code comment cleanups and additions.
Unit tests:
* Updated related tests and marked testBug29408() as broken (I can't find the
problem).
* Reduced leakage in UploadFromUrlTestSuite a bit.
Modified Paths:

* FSRepo is also supported for backwards compatibility.
*
* - name A unique name for the repository (but $wgLocalFileRepo
should be 'local').
+ * The name should consist of alpha-numberic characters.
* - backend A file backend name (see $wgFileBackends).
*
* For most core repos:
+ * - zones Associative array of zone names that each map to an
array with:
+ * container : backend container name the zone is in
+ * directory : root path within container for the zone
+ * Zones default to using <repo name>-<zone> as the
+ * container name and the container root as the zone
directory.
* - url Base public URL
* - hashLevels The number of directory levels for hash-based division
of files
* - thumbScriptUrl The URL for thumb.php (optional, not recommended)
