* 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. Mola2017-07-264-82/+279
| | | | | | | | | | | | | | | 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.

| | | | Implemented algorithm described in "File System Support for Delta Compression" paper, from "Joshua P. MacDonald".

* format/packfile: rename Seek to SeekFromStartSantiago M. Mola2017-04-263-6/+8
| | | | | | This has signature and behavior distinct from io.Seeker, go vet complains about this, so we change it to a different name to avoid confusion.

| | | | To be able to fix #261 we will move again to gopkg.in before v4 stable release.

* cache: move package to plumbingAntonio Jesus Navarro Perez2017-02-211-1/+1
| | | | Because cache package is only intended to be used at internal level, we move it to the plumbing package.

|\ | | | | Fix missing objects if they where deltified using ref-delta
| * 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.

* packfile: cache undeltified objects to improve decode performance (#218)Antonio Navarro Perez2017-01-251-8/+33
| | | | | * Simple object cache that keeps in memory the last undeltified objects. When no more objects can be kept into memory, the oldest one is deleted (FIFO). This speeds up packfile operations preventing redundant seeks and decodes.
