| | | | | | | | | | | | | | | | "clean" is not really dirty. If for some reason an entry is left on disk with a pointer on the rankings node but without the dirty flag set, we now recognize it as dirty the next time we read it from disk.

* Disk Cache: Second pass (and final) to allow multiple instancesrvargas@google.com2009-03-271-7/+12
| | | | | | | | | | | | | | | | | | | of BackendImpl. This cl takes care of all the histograms on the disk cache. Most of them have to be splitted in three so that we get separate data from different cache types. There are a few places where the complexity of splitting the histogram is not worth it so we just keep either all data together (if it makes sense), or just ignore data for some types of caches. note: Having multiple versions of a histogram but only one "active" for a given client is not the same as having multiple histograms working at the same time for different objects.

* Highlights of changes:hclam@chromium.org2009-03-131-5/+5
| | | | | | | | | | | | | | | | | | | 1. Added entry to ResourceResponseHead so that it contains either a base::PlatformFile (OS_WIN) or base::FileDescriptor (OS_POSIX) for passing the file handle from browser to renderer process. 2. Also added IPC messages for reporting download progress and ACK message for it. ResourceLoaderBridge::Peer::OnDownloadProgress is added so that the peer is notified of the download progress in the renderer process. 3. Load flag to kick start the resource loading for media files. LOAD_MEDIA_RESOURCE is added so that ResourceDispatcherHost knows how to use a different ResourceHandler for handling media resource request.

* New disk cache eviction algorithm (partial implementation).rvargas@google.com2009-03-061-21/+34
| | | | | | | | | | | | | | | | | | | | | | | | 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.org2009-03-021-2/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Disk cache: remove the hard coded list from rankings.ccrvargas@google.com2008-12-161-1/+1
| | | | | | | | | | | | | | | | The rankings module now works with any list, not just the first one. This is part of the support needed for new eviction algorithms. note: Rankings::CheckList() is basically the code that was implementing the old Rankings::SelfCheck() (moved with this cl). The disk cache behavior is not changing with this cl. Review URL: http://codereview.chromium.org/14141 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@7074 0039d316-1c4b-4281-b951-d872f2087c98
* Disk cache: Add support for an extra data stream for each cache entry.rvargas@google.com2008-12-041-9/+15
| | | | | | | | | | | | This is the first step to allow the http cache to store additional metadata for certain entries. The cache file format changes to version 2.0 so an effect of this cl is that the borwser will discard the old cache files.

* Switch MessagePumpForIO to use completion ports on Windows.rvargas@google.com2008-11-071-25/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cleanup the separation between MessagePumpForUI and MessagePumpForIO, and convert the latter to use Completion Ports instead of MsgWaitForMultipleobjects to sleep when idle. Remove all traces of Windows messages from MessagePumpForIO, remove the transitional API of completion port notifications and remove WatchObject API. Modify all callers of RegisterIOHandler so that they are no longer using RegisterIOContext, and also handle properly the new semantics of completion ports (notifications even when the IO completes immediately). Add a new interface to allow proper cleanup of disk cache (to replace code that was waiting for pending APCs from the destructor). Add a way for the message pump to perform cleanup of abandoned IO.
