* plumbing, storage: add bases to the common cacheJavi Fontan2018-08-222-0/+25
| | | | | | | | | | | | 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>
* plumbing/idxfile: object iterators returns entries in offset orderJavi Fontan2018-08-213-1/+85
| | | | | | | | | | | In the latest change the order was changed from offset order in packfiles to hash order. This makes reading all the objects not as efficient as before. It also created problems when the previous order was expected. Also added EntriesByOffset to indexes. Signed-off-by: Javi Fontan <jfontan@gmail.com>

| * packfile: improve Index memory representation to be more compactDavid Symonds2018-05-302-23/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using a map for offset indexing, use a sorted slice. Binary searching is fast, and a slice is much more compact. This has a negligible hit on speed, but has a significant impact on memory usage, especially for larger repos. benchmark old ns/op new ns/op delta BenchmarkIndexConstruction-12 15506506 14056098 -9.35% benchmark old allocs new allocs delta BenchmarkIndexConstruction-12 60764 60385 -0.62% benchmark old bytes new bytes delta BenchmarkIndexConstruction-12 4318145 3913169 -9.38% Signed-off-by: David Symonds <dsymonds@golang.org>

* plumbing: format: pktline, Accept oversized pkt-lines up to 65524 bytesJoseph Vusich2018-04-023-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | | The canonical Git client successfully decodes sideband packets up to 65524 bytes in length (4-byte header + 65520-byte payload). The Git protocol documentation was updated in August 2016 to reduce the maximum payload size to 65516 bytes, however old implementations still exist in the wild emitting 65520-byte payloads. As there is no technical difficulty with accepting (not emitting) larger payload sizes, this change adjusts the limit check to allow successful decoding of packets up to 65524 bytes. This change increases compatibility with the current canonical Git implementation.

|/ | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | 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 Fontan2018-01-161-0/+2
| | | | | | | | | | | 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>
