* storage/dotgit: add KeepDescriptors optionJavi Fontan2018-09-041-1/+9
| | | | | | | | | | This option maintains packfile file descriptors opened after reading objects from them. It improves performance as it does not have to be opening packfiles each time an object is needed. Also adds Close to EncodedObjectStorer to close all the files manualy.

* plumbing, storage: add bases to the common cacheJavi Fontan2018-08-221-2/+16
| | | | | | | | | | | | After clone only resolved deltas were added to the cache. This caused slowdowns in small repositories where most objects can be held in cache. It also makes packfiles reuse delta cache from the store. Previously it created a new delta cache each time a packfile object was created. This also slowed down a bit accessing objects and had an impact on memory consumption when bases are added to the cache. Signed-off-by: Javi Fontan <jfontan@gmail.com>

* Enforce the use of cache in packfile decoderJavi Fontan2017-12-201-5/+2
| | | | | | | | | | | | | | | | | Decoder object can make use of an object cache to speed up processing. Previously the only way to specify it was changing manually the struct generated by NewDecodeForFile. This lead to some instances to be created without it and penalized performance. Now the cache should be explicitly passed to the constructor function. NewDecoder now creates objects with a cache using the default size. A new helper function was added to create cache objects with the default size as this becomes a common task now: cache.NewObjectLRUDefault() Signed-off-by: Javi Fontan <jfontan@gmail.com>
* storage: filesystem, add support for git alternates (#663)Sunny2017-12-061-0/+21
| | | | This change adds a new method Alternates() in DotGit to check and query alternate source.

* plumbing: add `HasEncodedObject` method to StorerJeremy Stribling2017-11-291-0/+26
| | | | | | | This allows the user to check whether an object exists, without reading all the object data from storage. Issue: KBFS-2445

| * storage: reuse deltas from packfilesSantiago M. Mola2017-07-271-7/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * plumbing: add DeltaObject interface for EncodedObjects that are deltas and hold additional information about them, such as the hash of the base object. * plumbing/storer: add DeltaObjectStorer interface for object storers that can return DeltaObject. Note that calls to EncodedObject will never return instances of DeltaObject. That requires explicit calls to DeltaObject. * storage/filesystem: implement DeltaObjectStorer interface. * plumbing/packfile: packfile encoder now supports reusing deltas that are already computed (e.g. from an existing packfile) if the storage implements DeltaObjectStorer. Reusing deltas boosts performance of packfile generation (e.g. on push).

* packfile: create packfile.Index and reuse itSantiago M. Mola2017-07-261-33/+18
| | | | | | | | | | | | | | | There was an internal type (i.e. storage/filesystem.idx) to use as in-memory index for packfiles. This was not convenient to reuse in the packfile. This commit creates a new representation (format/packfile.Index) that can be converted to and from idxfile.Idxfile. A packfile.Index now contains the functionality that was scattered on storage/filesystem.idx and packfile.Decoder's internals. storage/filesystem now reuses packfile.Index instances and this also results in higher cache hit ratios when resolving deltas.

* Fix missing objects if they where deltified using ref-deltaAntonio Jesus Navarro Perez2017-02-071-3/+6
| | | | | - Deleted invalid logic that returned nil if an ref-delta was not found into the decoder index. This logic was missing objects if it was deltified using ref-deltas. - Now, to avoid that problem, index is mandatory to decode correctly a packfile of a specific type. Decoder.SetOffsets method now is called into the EncodedObjectIterator to avoid this problem.
