From: Aaron Schulz Date: Sat, 7 Jan 2012 01:33:23 +0000 (+0000) Subject: In FileBackend/FileOp: X-Git-Tag: 1.31.0-rc.0~25459 X-Git-Url: https://git.cyclocoop.org//%22?a=commitdiff_plain;h=7d923a93600652675f013776de842ba5003b69e0;p=lhc%2Fweb%2Fwiklou.git 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 -- (or - 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. --- diff --git a/includes/DefaultSettings.php b/includes/DefaultSettings.php index a9a203ba2c..7fb973cc3e 100644 --- a/includes/DefaultSettings.php +++ b/includes/DefaultSettings.php @@ -303,9 +303,15 @@ $wgImgAuthPublicTest = true; * 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 - 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) diff --git a/includes/filerepo/FSRepo.php b/includes/filerepo/FSRepo.php index e7a1545c69..22dbdefc10 100644 --- a/includes/filerepo/FSRepo.php +++ b/includes/filerepo/FSRepo.php @@ -30,15 +30,16 @@ class FSRepo extends FileRepo { ? $info['fileMode'] : 0644; + $repoName = $info['name']; // Get the FS backend configuration $backend = new FSFileBackend( array( 'name' => $info['name'] .
