* plumbing: format/packfile, prevent large objects from being read into memory ↵v5.4.0zeripath2021-05-121-0/+79
| | | | | | | | | | | completely (#303) 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. Signed-off-by: Andrew Thornton <art27@cantab.net>

* Support partial hashes in Repository.ResolveRevision.David Symonds2020-07-162-3/+109
| | | | | | | | | | | | | Like `git rev-parse <prefix>`, this enumerates the hashes of objects with the given prefix and adds them to the list of candidates for resolution. This has an exhaustive slow path, which requires enumerating all objects and filtering each one, but also a couple of fast paths for common cases. There's room for future work to make this faster; TODOs have been left for that. Fixes #135.

* Support `.git/commondir` repository layoutTimofey Kirillov2020-06-153-0/+241
| | | | | | | | | | | | | | | | Git creates `.git/commondir` when there are custom worktrees (see "git worktree add" related commands). `.git/commondir` in such case contains a link to another dot-git repository tree, which could contain some folders like: - objects; - config; - refs; - etc. In this PR a new dotgit.RepositoryFilesystem struct is defined, which is billy.Filesystem interface compatible object-wrapper, that can handle commondir and dispatch all operations to the correct file path. `git.PlainOpen` remain unchanged, but `git.PlainOpenWithOptions` has a new option: `PlainOpenOptions.EnableDotGitCommonDir=true|false` (which is false by default). When `EnableDotGitCommonDir=true` repository-open procedure will read `.git/commondir` (if it exists) and then create dotgit.RepositoryFilesystem object initialized with 2 filesystems. This object then passed into storage and then into dotgit.DotGit as `billy.Filesystem` interface. This object will catch all filesystem operations and dispatch to the correct repository-filesystem (dot-git or common-dot-git) according to the rules described in the doc: https://git-scm.com/docs/gitrepository-layout#Documentation/gitrepository-layout.txt. EnableDotGitCommonDir option will only work with the filesystem-backed storage. Also worktree_test.go has been adopted from an older, already existing existing PR: https://github.com/src-d/go-git/pull/1098. This PR needs new fixtures added in the following PR: https://github.com/go-git/go-git-fixtures/pull/1.

* storage/filesystem: dotgit, sanity check provided reference pathKyle Evans2020-04-232-1/+12
| | | | | | | | | | On some operating systems, read() of a directory fd may actually succeed and return garbage resembling on-disk contents. As a result, dotgit may return successful from readReferenceFile() when it should in-fact not. This fixes readReferenceFile() on FreeBSD. Signed-off-by: Kyle Evans <kevans@FreeBSD.org>
* storage/filesystem: dotgit, add a test for reading refs from a directoryKyle Evans2020-04-231-1/+13
| | | | | | Specifically, the problem demonstrated is that on some OS (e.g. FreeBSD), read() on a directory will succeed. The current implementation will accept that and return incorrect results, rather than rejecting the directory.

Those checks certainly never harm, but please review thoroughly and let me know.

| | | | | | | | | | This option maintains packfile file descriptors opened after reading objects from them.

* git: add Static option to PlainOpenJavi Fontan2018-08-301-3/+179
| | | | | | | | | | | | | | | | Also adds Static configuration to Storage and DotGit. This option means that the git repository is not expected to be modified while open and enables some optimizations. Each time a file is accessed the storer tries to open an object file for the requested hash. When this is done for a lot of objects it is expensive. With Static option a list of object files is generated the first time an object is accessed and used to check if exists instead of using system calls. A similar optimization is done for packfiles.

* storage/filesystem: avoid norwfs build flagSantiago M. Mola2018-06-215-94/+82
| | | | | | | | | | | | | | | | | norwfs build flag was used to work on filesystems that do not support neither opening a file in read/write mode or renaming a file (e.f. sivafs). This had two problems: - go-git could not be compiled to work properly both with regular filesystems and limited filesystems at the same time. - the norwfs trick was not available on Windows. This PR removes the norwfs build flag, as well as the windows conditional flag on the dotgit package. For the file open mode, we use the new billy capabilities, to check at runtime if the filesystem supports opening a file in read/write mode or not. For the renaming, we just try and fallback to alternative methods if billy.ErrNotSupported is returned. Signed-off-by: Santiago M. Mola <santi@mola.io>
