* revlist: do not revisit ancestors as long as all branches are visitedMiguel Molina2017-09-122-3/+84
| | | | | | | | | | This change is the fixed version of the previous performance improvement that was reverted due to some bogus logic. Now it's fixed and only stops the iteration if and only if all of the branches we've come across have been visited, being a branch a parent commit of a commit we've visited.

| * plumbing: the commit walker can skip externally-seen commitsJeremy Stribling2017-09-093-11/+41
| | | | | | | | | | | | | | | | | | | | When the revlist is computing the set of hashes needed to transfer, it doesn't need to walk over commits it has already processed. So, it can instruct the commit walker not to walk those commits by passing in its own `seen` map. For a 36K object repo, this brought the time for `revlist.Objects` down from 50s to 30s.
* | config: support a configurable, and turn-off-able, pack.windowJeremy Stribling2017-09-117-39/+92
|/ | | | | | | | | | | | | | | | | | | | 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).

* plumbing: use sliding window in delta calculations, like git CLJeremy Stribling2017-08-282-1/+23
| | | | | | | | | | This sets a default sliding window of 10 for the delta calculation, just like git CL: https://git-scm.com/docs/git-pack-objects#git-pack-objects---windowltngt For a big-ish repo with 35K objects (17K commits), this reduced the time for calling `deltaSelection.walk` during a push from more than 14 minutes to about a minute.

| | | | | | | | | | | | When git-core isn't in the user's PATH, we need to use `LookPath` to verify the existence of the executable, rather than `os.Stat`, so that on Windows it will search for files with executable suffixes.
* | plumbing: use `seen` map in tree walkerJeremy Stribling2017-08-275-11/+43
|/ | | | | | | This helps avoids iterating down the same trees for every commit. For a big-ish repo with 35K objects (17K commits), this reduced the time for calling `revlist.Objects` during a push (with 0 hashes to ignore) from more than ten minutes to less than a minute.

| | | | | | | | | | | | | | | | | | | | | Usually we call revlist.Objects ignoring a set of commits. This is not enough to ignore everything reachable from such set, so we first get all objects reachable from the ignored set and then walk the tree again ignoring that new set.

* packfile: create packfile.Index and reuse itSantiago M. Mola2017-07-269-93/+292
| | | | | | | | | | | | | | | 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.
