* plumbing: Properly support skipping of non-mandatory extensionsAlexander Block2024-04-061-8/+30
| | | | | | | | | Before this, go-git would prematurely bail out of extensions processing when an unknown extension was encountered. This had two issues: 1. It did not account for mandatory (lower case header) extensions 2. It did not properly update the calculated hash, leading to an "invalid checksum" error.
* plumbing: Properly detect EOF when reading index extensionsAlexander Block2024-04-051-34/+36
| | | | | | | | | Before this, go-git was relying on the peeked header to not include a valid 4 char string header. While doing this, it did not differentiate between the errournously read final hash and an unknown extension. This made it impossible to properly skip unknown optional extensions while detecting EOF early enough.

* plumbing: Optimise memory consumption for filesystem storagePaulo Gomes2023-10-282-50/+247
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, as part of building the index representation, the resolveObject func would create an interim plumbing.MemoryObject, which would then be saved into storage via storage.SetEncodedObject. This meant that objects would be unnecessarily loaded into memory, to then be saved into disk. The changes streamlines this process by: - Introducing the LazyObjectWriter interface which enables the write operation to take places directly against the filesystem-based storage. - Leverage multi-writers to process the input data once, while targeting multiple writers (e.g. hasher and storage). An additional change relates to the caching of object info children within Parser.get. The cache is now skipped when a seekable filesystem is being used. The impact of the changes can be observed when using seekable filesystem storages, especially when cloning large repositories. The stats below were captured by adapting the BenchmarkPlainClone test to clone https://github.com/torvalds/linux.git: pkg: github.com/go-git/go-git/v5 cpu: Intel(R) Core(TM) i9-10885H CPU @ 2.40GHz │ /tmp/old │ /tmp/new │ │ sec/op │ sec/op vs base │ PlainClone-16 41.68 ± 17% 48.04 ± 9% +15.27% (p=0.015 n=6) │ /tmp/old │ /tmp/new │ │ B/op │ B/op vs base │ PlainClone-16 1127.8Mi ± 7% 256.7Mi ± 50% -77.23% (p=0.002 n=6) │ /tmp/old │ /tmp/new │ │ allocs/op │ allocs/op vs base │ PlainClone-16 3.125M ± 0% 3.800M ± 0% +21.60% (p=0.002 n=6) Notice that on average the memory consumption per operation is over 75% smaller. The time per operation increased by 15%, which may actual be less on long running applications, due to the decreased GC pressure and the garbage collection costs.

* plumbing: commitgraph, fix types and handle commit-graph-chainsAndrew Thornton2023-10-0814-55/+1265
| | | | | | | | | Unfortunately the original variant makes some incorrect typing assumptions about commit-graphs which make handling graph chains difficult to do correctly. This creates a new subpackage and deprecates the old one. It then adds support commit graph chains. Signed-off-by: Andrew Thornton <art27@cantab.net>

| | | | | | | | | | | | | | | | | | | | | | | | The variable length for plumbing.Hash is defined at build time, blocked by tag sha256. This approach was a trade-off between keeping backwards compatibility while making progress towards supporting SHA256 with a small amount of changes.

|/ | | | | | | | | | | In a self-contained pack file delta references might point to base objects stored later in the file.

| | | | | | | | | | | | | | | | | | | Implement the same SHA1 collision resistent algorithm used by both the Git CLI and libgit2. Only commits with input that match the unavoidable bit conditions will be further processed, which will result in different hashes. Which is the same behaviour experienced in the Git CLI and Libgit2. Users can override the hash algorithm used with: hash.RegisterHash(crypto.SHA1, sha1.New) xref links: https://github.com/libgit2/libgit2/pull/4136/commits/2dfd1294f7a694bfa9e864a9489ae3cb318a5ed0 https://github.com/git/git/commit/28dc98e343ca4eb370a29ceec4c19beac9b5c01e Signed-off-by: Paulo Gomes <pjbgf@linux.com>

This change checks the length of the remaining pattern before it references an element of that slice. With a single trailing asterisk paths deeper than the pattern should not get the attributes. For example with the following `.gitattributes` file: thirdparty/* linguist-vendored This is how git handles it: $ git check-attr --all thirdparty/README.md thirdparty/README.md: diff: markdown thirdparty/README.md: linguist-vendored: set $ git check-attr --all thirdparty/package/README.md thirdparty/package/README.md: diff: markdown
