I continued working on this today, so here's a better version. Changes since last patch: o. Requests to copy-to-local are now also handled by the indexer, instead of by the extractor o. Heuristic scanner finds local media art first, and copies from it if found as first heuristic match o. Proper check in configure.ac for strcasestr o. There were linking problems in the test-tools for tracker-extract, I fixed them in this patch (by providing dummy functions) o. Restored all necessary locations for requesting thumbnails of the newly created album art o. Eliminated the need for TrackerHal in tracker-extract (which will make Ivan as happy as a little boy who has just found Easter eggs), removed the construction of it from the main function and from the tests for tracker-extract. o. Cleaned up use of TrackerHal in the code that now runs in the indexer, it all uses hal from private->hal now instead. Made it cope with not HAVE_HAL too. I'll notify you tomorrow about it if I change more things today, Martyn. But feel free to start reviewing this one already. On Fri, 2009-04-10 at 17:40 +0200, Philip Van Hoof wrote:Hackers! Currently Tracker's media file extractor will on top of trying to extract embedded media art from files, perform a heuristic on the directory of the media file. The reason why it does this heuristic is to find album art related to the media file. Usually are media files grouped together in a directory, though. For example like this: /location/Freaky Freak/The greatest hits/Freaky-Freak_-_The-greatest-hits_-_I-can-sing.mp3 /location/Freaky Freak/The greatest hits/Freaky-Freak_-_The-greatest-hits_-_You-can-sing.mp3 /location/Freaky Freak/The greatest hits/Freaky-Freak_-_The-greatest-hits_-_We-can-sing.mp3 /location/Freaky Freak/The greatest hits/Freaky-Freak_-_The-greatest-hits_-_They-can-sing.mp3 Or whatever filenaming format the w3ird peoples on thiz planetz have used for their albums, songs, media files and etcetera. Right now will the extractor foreach file in such a directory repeat the complete heuristic. With this patch we'll throw the request for a heuristic back to the indexer. The indexer has a queue where it also merges the requests together. In the patch the indexer does this by forming a key using the dirname, album and artist. Which means that if a request for a heuristic is made for ten files sang by the same artist, grouped into the same album, stored in the same directory, which is kinda common by the way, I'm again making my sentences too long, making it hard for people to read them, then the indexer will simply merge those ten together and perform just one heuristic instead. Saving precious computar cycles. It's quite a refactor, and this close to a next 0.6.x release it would I think be good if a few extra couple of eyes would review and test the code before I push it.
