* 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.

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
