| * Add a setRef version that supports non rw fsJavi Fontan2017-12-213-29/+62
| | | | | | | | | | | | | | | | | | There are some filesystems that do not support opening the files in read and write modes at the same time. The method SetRef is split in files with an extra version that only writes the reference. It can be activated with -tags norwfs on building. Signed-off-by: Javi Fontan <jfontan@gmail.com>

* | Enforce the use of cache in packfile decoderJavi Fontan2017-12-201-5/+2
|/ | | | | | | | | | | | | | | | | 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>

* dotgit: rewrite packed-refs while holding lockJeremy Stribling2017-11-303-60/+103
| | | | | | Windows file system doesn't let us rename over a file while holding that file's lock, so use rewrite as a last resort. It could result in a partially-written file, if there's a failure at the wrong time.
* dotgit: open+lock packed-refs file until it doesn't changeJeremy Stribling2017-11-291-18/+46
| | | | Windows doesn't like it when we re-open a file we already have locked.

* dotgit: during rewriting, re-open packed-refs after lockingJeremy Stribling2017-11-291-9/+21
| | | | | | The file could have been completely replaced while waiting for the lock, so we need to re-open, otherwise we might be reading a stale file that has already been deleted/overwritten.

* filesystem: implement PackRefs()Jeremy Stribling2017-11-293-0/+195
| | | | | | | | | | 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
* all: simplificationferhat elmas2017-11-292-7/+3
| | | | | | | | | | - no length for map initialization - don't check for boolean/error return - don't format string - use string method of bytes buffer instead of converting bytes to string - use `strings.Contains` instead of `strings.Index` - use `bytes.Equal` instead of `bytes.Compare`

| | | | | | Now there's only two ways of getting a reference, by checking under refs/ directory or in packed-refs. refs/ directory is checked using a direct read by reference name and packed refs are cached until they have been changed. Signed-off-by: Miguel Molina <miguel@erizocosmi.co>

| * storage: reuse deltas from packfilesSantiago M. Mola2017-07-274-9/+145
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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).

* packfile: create packfile.Index and reuse itSantiago M. Mola2017-07-262-45/+26
| | | | | | | | | | | | | | | 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.
