* plumbing: format/packfile, check nil objects in ObjectToPackJavi Fontan2018-01-252-8/+12
| | | | | | | SetOriginal now skips setting resolved values if the provided object is nil. BackToOriginal also skips nil Original objects. Signed-off-by: Javi Fontan <jfontan@gmail.com>
* plumbing: format/packfile, fix crash with cycle deltasJavi Fontan2018-01-244-1/+51
| | | | | | | | | | | | Resolving cycles relied on ObjectToPack objects having Original. This is no longer true with the changes from #720. This commit changes: * Save original type, hash and size in ObjectToPack * Use SetObject to set both Original and resolved type, hash and size * Restore original object before using BackToOriginal (cycle resolution) * Update encoder test to check this case Signed-off-by: Javi Fontan <jfontan@gmail.com>

* plumbing: packfile, Add a buffer to crc writer.Javi Fontan2018-01-211-9/+31
| | | | | | | | | | | crc update with block smaller than 16 bytes uses a slower version of the function. ReadByte is heavily used by zlib inflate so most of the time crc is update byte by byte. A new Flush method is added to the scanner to flush this crc writer cache. It is only called when the Scanner reader is a teeReader. Signed-off-by: Javi Fontan <jfontan@gmail.com>

* Modify cache to delete more than one item to free spaceJavi Fontan2018-01-162-5/+3
| | | | | | | | | | | The previous version could only delete the oldest used object. If the object to cache was bigger than the space freed it could not be added. Also the decoder adds bases to the cache when they are needed. This change increases the speed creating indexes 2x. Signed-off-by: Javi Fontan <jfontan@gmail.com>
* Clean reconstructed objects outside pack windowJavi Fontan2018-01-111-13/+19
| | | | | | | | | | | Object walk reconstructs delta objects but these are not cleaned up after they got out the pack window. Without this change all reconstructed objects reside in memory. restoreOriginal call is moved before calling Size(). Now we can not guarantee that the object is already undeltified.

| * Enforce the use of cache in packfile decoderJavi Fontan2017-12-204-12/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | Improve delta reutilizationAntonio Jesus Navarro Perez2017-12-205-29/+152
|/ | | | | | | | | | | - Remove wrong 'if' on delta selector that causes poor delta reutilizations - packfile.Encoder now can write deltas and objects in a non specific order - ObjectToPack now saves the Offset on the packfile to be able to obtain base offset in a recursive manner and write them before the delta itself - Added encoder test to check cyclic delta chains - Check the output packfile hash in all encoder tests Signed-off-by: Antonio Jesus Navarro Perez <antnavper@gmail.com>

* | filesystem: implement PackRefs()Jeremy Stribling2017-11-291-0/+2
|/ | | | | | | | | | Currently this implementation is only valid for kbfsgit, since it assumes some things about the filesystem not being updated during the packing, and about conflict resolution rules. In the future, it would be nice to replace this with a more general one, and move this kbfsgit-optimized implementation into kbfsgit. Issue: KBFS-2517
