* Disk cache: Add a method to cancel pending sparse operations.rvargas@google.com2009-10-081-0/+2
| | | | | | | | | | | | | | | | | | | The sparse IO methods require exclusive use of the cache entry and they complain when that requirement is violated. When the user cancels a request and reissues another one to the same entry, we may be waiting for the previous operation to finish when we receive a new IO request, so we fail. This CL add a way for the HTTP cache to cancel IO operations and get a notification when the disk cache is able to operate on that entry again.

| | | | | | | | | | | | | | | | | | | | | | | | | | be able to return the key of an open entry. Whenever a critical corruption is detected by the disk cache, the backend disables itself and starts failing all requests until it's able to re-create the backing store. Key's longer than 928 bytes are not stored inside the entry itself, so a file object is required to access them. The backend will reject any request for a file object after it is disabled, so a user's request for the key of an open entry will also fail. Now we keep a pointer to the related file object (if needed) so that we don't have to ask the backend for it when the user requests the current key.

* Disk cache: Add explicit support for eviction / deletionrvargas@google.com2009-07-091-0/+16
| | | | | | | | | | | | | | | | | | | | | | | of sparse entries. I started to add code to modify the children_map of the parent entry when a child is evicted but that ended up being too much trouble for too little gain. We have to be prepared to handle the case of not finding a child entry because there is no way to make sure that the process doesn't go away at any time, so adding a lot of complexity just to avoid an extra entry lookup is just not worth it. On the other hand, potentially freeing up a lot of space when a sparse entry is deleted (insetad of just waiting for the eviction code to do the cleanup) seems like a good thing.

* Disk cache: Keep a map of all open entries.rvargas@google.com2009-07-071-4/+4
| | | | | | | | | | | | | | | | | We still have a few crashes when for some reason we believe an entry is not dirty and we follow the pointer stored by its rankings node only to crash while accessing the memory. I have no explanation to why the dirty id matches the current one (a page boundary issue maybe?), but having a map with all open entries solves the issue of having to follow pointers from disk.

* Remove code path that passes a file handle to the rendererhclam@chromium.org2009-05-291-4/+0
| | | | | | | | | | | | | | | | | | | | | | Since the code now does range request without any caching the code path for passing file handle is not used any more. Changes: 1. Remove response_data_file in webkit_glue::ResourceResponseHead 2. Remove response_data_file in net::ResourceInfo 3. Remove code that passes file handle using IPC 4. Remove code that passes file hadnle from network layer to ResourceDispatcherHost 5. Remove MediaResourceHandler 6. Remove code in disk_cache that expose the file handle 7. Remove ChromeURLRequestContext::CreateOffTheRecordForMedia() so no more OTR request context for media, in OTR mode simply memory cache is used 8.

* New disk cache eviction algorithm (partial implementation).rvargas@google.com2009-03-061-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | Disabled by a #def. When enabled, file format 2.1 is used, with a possible update from ver 2.0. If a version with this code disabled is run after the upgrade, it will just discard the file and go back to 2.0. We now put some of those extra list to use! Entries are separated into various lists depending on how often are used, and we keep track of previously evicted entries. If the new algorithm is not enabled, most of the code just goes through a different path (with the old code instead of the new one). One notable exception is OpenFollowingEntry, used to enumerate the entries on the cache; the code changed significantly to support the new version of the "cache iterator", but functionally should do the same as the current code.

* Proposed change to support resource loading for media files.hclam@chromium.org2009-03-021-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Highlights of changes: - Added methods to disk_cache::Entry: - Entry::PrepareTargetAsExternalFile(int index) Prepare a stream in an entry to use external file for storage. - Entry::GetExternalFile(int index) Get the external file backing the stream in the entry. - Added a property "CacheType type_" to HttpCache, along with setter and getter. There shall be two cache types, COMMON_CACHE and MEDIA_CACHE for distinguishing between different purpose of HttpCache. We have this property to trigger special behavior for caching needs of media files. - Added static methods to ChromeURLRequestContext - ChromeURLRequestContext::CreateOriginalForMedia Create a URLRequestContext for media files for the original profile. - ChromeURLRequestContext::CreateOffTheRecordForMedia Create a URLRequestContext for media files for off the record profile. - Added method to Profile interface. - GetRequestContextForMedia To get the request context for media files from the context. Design decissions: - Enforce writing to external file by calling methods to Entry rather than construct Backend by a different flag. Since we only want a valid and full response to go into an external file rather than redirection response or erroneous response, we should let HttpCache::Transaction to decide when to have an external file for response data. We eliminate a lot of useless external cache files. - Adding the CacheType enum and property to HttpCache, we could allow possible (?) future extensions to HttpCache to handle other different caching needs. And there's no need to add change constructors of HttpCache, but maybe we should add a specific constructor to accomodate a media HttpCache? - Adding Profile::GetRequestContextForMedia() Since we will need to use this new request context in ResourceDispatcherHost, I think the best place to keep it is in the profile. Also we will expose to user that there's a separate cache for media, so it's better to expose it in the Profile level to allow settings to the media cache, e.g. max file size, etc. Review URL: http://codereview.chromium.org/19747 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@10745 0039d316-1c4b-4281-b951-d872f2087c98
