* *: Support variable length plumbing.HashPaulo Gomes2023-03-081-4/+5
| | | | | | | | | | | | The variable length for plumbing.Hash is defined at build time, blocked by tag sha256. This approach was a trade-off between keeping backwards compatibility while making progress towards supporting SHA256 with a small amount of changes. Relates to the SHA256 implementation, defined in #706. Signed-off-by: Paulo Gomes <pjbgf@linux.com>
* plumbing: format/packfile, prevent large objects from being read into memory ↵zeripath2021-06-301-1/+1
| | | | | | | | | | | | | | | completely (#330) This PR adds code to prevent large objects from being read into memory from packfiles or the filesystem. Objects greater than 1Mb are now no longer directly stored in the cache or read completely into memory. This PR differs and improves the previous broken #323 by fixing several bugs in the reader and transparently wrapping ReaderAt as a Reader. Signed-off-by: Andrew Thornton <art27@cantab.net>

* plumbing: format/packfile, fix panic retrieving object hash.Javi Fontan2018-02-091-2/+2
| | | | | | | | | | | | | | | | In some cases the original data is not saved before it is cleaned and forces a panic when it's needed. The change adds ObjectToPack.CleanOriginal to be used to clean original object instead of: object.Original = nil Now when the Original data is freed because it's no longer in the pack window a SetOriginal call is done to make sure that Size, Hash and Size data is not lost.

* plumbing: format/packfile, check nil objects in ObjectToPackJavi Fontan2018-01-251-2/+2
| | | | | | | 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 Fontan2018-01-241-0/+21
| | | | | | | | | | | | 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>
* Improve delta reutilizationAntonio Jesus Navarro Perez2017-12-201-4/+77
| | | | | | | | | | | - 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>

* config: support a configurable, and turn-off-able, pack.windowJeremy Stribling2017-09-111-4/+4
| | | | | | | | | | | | | | | | | | | | One use of go-git is to transfer git data from a non-standard git repo (not stored in a file system, for example) to a "remote" backed by a standard, local .git repo. In this scenario, delta compression is not needed to reduce transfer time over the "network", because there is no network. The underlying storage layer has already taken care of the data tranfer, and sending the objects to local .git storage doesn't require compression. So this PR gives the user the option to turn off compression when it isn't needed. Of course, this results in a larger, uncompressed local .git repo, but the user can then run git gc or git repack on that repo if they care about the storage costs. Turning the pack window to 0 on reduces total push time of a 36K repo by 50 seconds (out of a pre-PR total of 3m26s).
* storage: reuse deltas from packfilesSantiago M. Mola2017-07-271-76/+0
| | | | | | | | | | | | | | | | | | | * 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.
