Corey Farrell	a6e5bae3ef	Remove ASTERISK_REGISTER_FILE. ... ASTERISK_REGISTER_FILE no longer has any purpose so this commit removes all traces of it. Previously exported symbols removed: * __ast_register_file * __ast_unregister_file * ast_complete_source_filename This also removes the mtx_prof static variable that was declared when MTX_PROFILE was enabled. This variable was only used in lock.c so it is now initialized in that file only. ASTERISK-26480 #close Change-Id: I1074af07d71f9e159c48ef36631aa432c86f9966	9 years ago
Joshua Colp	72a897c534	media_cache: Demote warning to debug as it may occur often. ... The file playback system will now query the media cache and then the old file functionality. Under normal conditions this will result in the cache failing to retrieve a file causing a warning message to get output each time a file is played back. This change demotes this warning to a debug message. Change-Id: Ib72246ba300b5cce32774bfb3c26634bfb708624	10 years ago
Matt Jordan	791b4c9f81	main/media_cache: Provide an extension on the local file associated with a URI ... This patch does the following: First, it addresses file extension handling in the media cache. The media core in Asterisk is a bit interesting in that it wants: * A file to have an extension on it. That extension is used to associate the file with a defined format module. * The filename passed to the core to not have an extension on it. This allows the core to match the available file formats with the format a channel is capable of handling. Unfortunately, this makes the current implementation a bit lacking in the media cache. By default, we do not store the extension of a retrieved URI on the local file that is created. As a result, the media core does not know what format the file is, and the file is ignored. Modifying the file outside of the media core is bad, as we would not be able to update the internal ast_bucket_file's path. At the same time, we do not want to pass the extension out in the file_path parameter in ast_media_cache_retrieve. This parameter is intended to be fed into the media core; if we passed the extension, all callers would have to strip it off. Thus, this patch does the following: * If there is an extension specified in the URL, we append it to the local file name (if a preferred file name isn't specified), and we store that in the local file path. * The extension, however, is stripped off of the file_path parameter passed back out of ast_media_cache_retrieve. Second, this patch causes stale items to be completely removed from the system. Prior to this patch, sound files could be orphaned due to the bucket referencing the file being deleted, but the file itself not being removed. This is now addressed by explicitly calling ast_bucket_file_delete on the bucket_file when it is deemed to be stale. Note that this only happen when we know we will attempt to retrieve the resource again. Finally, this patch changes the AO2 container holding media items to just use a regular mutex. The usage for this container already assumed it was a plain mutex, and - given that retrieval of an item can cause it to be replaced in the container - a mutex makes more sense than a read/write lock.

Matt Jordan	ef82190804	media cache: Add CLI commands ... This patch adds five CLI commands for the media cache: * 'media cache show all' - display a summary of all items in the media cache. * 'media cache show <uri>' - display detailed information about a single item in the media cache. * 'media cache delete <uri>' - remove an item from the media cache, and inform the bucket backend for the URI scheme to remove the item as well. * 'media cache refresh <uri>' - refresh a URI. If the item does not exist in the media cache, the bucket backend will pull down the media associated with the URI and create the item in the cache. * 'media cache create <uri>' - create an item in the media cache from some local media storage. Note that the bucket backend for the URI scheme must still permit the item creation. Change-Id: Id1c5707a3b8e2d96b56e4691a46a936cd171f4ae	11 years ago
Matthew Jordan	3ea0d38396	media cache: Add a core API and facade for a backend agnostic media cache ... This patch adds a new API to the Asterisk core that acts as a media cache. The core API itself is mostly a thin wrapper around some bucket API provided implementation that itself acts as the mechanism of retrieval for media. The media cache API in the core provides the following: * A very thin in-memory cache of the active bucket_file items. Unlike a more traditional cache, it provides no expiration mechanisms. Most queries that hit the in-memory cache will also call into the bucket implementations as well. The bucket implementations are responsible for determining whether or not the active record is active and valid. This makes sense for the most likely implementation of a media cache backend, i.e., HTTP. The HTTP layer itself is the actual arbiter of whether or not a record is truly active; as such, the in-memory cache in the core has to defer to it. * The ability to create new items in the media cache from local resources. This allows for re-creation of items in the cache on restart. * Synchronization of items in the media cache to the AstDB. This also includes various pieces of important metadata. The API provides sufficient access that higher level APIs, such as the file or app APIs, do not have to worry about the semantics of the bucket APIs when needing to playback a resource. In addition, this patch provides unit tests for the media cache API. The unit tests use a fake bucket backend to verify correctness. Change-Id: I11227abbf14d8929eeb140ddd101dd5c3820391e	11 years ago
