* plumbing: add IsDelta method to ObjectTypeSantiago M. Mola2017-07-271-6/+2
| | | | | ObjectType.IsDelta is a convenience function to match both offset and reference delta types.
* storage: reuse deltas from packfilesSantiago M. Mola2017-07-275-98/+293
| | | | | | | | | | | | | | | | | | | * 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).
* test: improve packfile.Encoder testsSantiago M. Mola2017-07-271-54/+68
| | | | | | | * Improve checks for encode/decode. * Make it easier to extend this test with more storage backends.
* storage/filesystem: reuse delta cacheSantiago M. Mola2017-07-271-10/+22
| | | | | Reuse delta base object cache for packfile decoders across multiple instances.
* plumbing/cache: use more explicit interfaceSantiago M. Mola2017-07-271-7/+6
| | | | | | * renamed Add to Put * Get returns a second bool value to indicate if there was hit or miss.

* packfile: create packfile.Index and reuse itSantiago M. Mola2017-07-269-93/+292
| | | | | | | | | | | | | | | 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 Perez2017-02-072-7/+65
| | | | | | | | | | - 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.
