* 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
