* Merge pull request #707 from pjbgf/experimental-sha256Paulo Gomes2023-04-1110-22/+74
|\ | | | | *: Add support for initializing SHA256 repositories
| * *: Support variable length plumbing.HashPaulo Gomes2023-03-089-22/+21
| | | | | | | | | | | | | | | | | | | | | | | | 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. Relates to the SHA256 implementation, defined in #706. Signed-off-by: Paulo Gomes <pjbgf@linux.com>

* | plumbing: resolve non-external delta referencesZauberNerd2023-03-232-0/+22
|/ | | | | | | | | | | In a self-contained pack file delta references might point to base objects stored later in the file. In this case we need to replace placeholders for external refs with the actual base object and update the children references. Fixes: #484 Co-authored-by: Markus Wolf <mail@markus-wolf.de>
* sha1: Add collision resistent implementationPaulo Gomes2022-11-255-14/+15
| | | | | | | | | | | | | | | | | | | 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>

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a path is deeper than the single asterisk pattern the code would crash with a "index out of range". 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

For example, ``` object_walker.go:63:10: error strings should not be capitalized (ST1005) object_walker.go:101:10: error strings should not be capitalized (ST1005) object_walker.go:101:10: error strings should not end with punctuation or a newline (ST1005) plumbing/format/commitgraph/file.go:17:26: error strings should not be capitalized (ST1005) ``` This fixes all instances of this issue reported by staticcheck.

| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the initial logic to support a simple sparse checkout where directories to be included can be specified in CheckoutOptions. This change doesn't fully support the sparse patterns, nor does this change include the optimization to collapse flie entries in ithe index that are excluded via the sparse checkout directory patterns included under the parent directory.

| | | | | | | | | | | | | | | | | | | | | | | | Currently the index encoder does not support the v3 index format. This change adds support to the encoder. This helps to unlock sparse checkout.

* plumbing: format/packfile, prevent large objects from being read into memory ↵zeripath2021-06-308-33/+405
| | | | | | | | | | | | | | | completely (#330) 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. This PR differs and improves the previous broken #323 by fixing several bugs in the reader and transparently wrapping ReaderAt as a Reader. Signed-off-by: Andrew Thornton <art27@cantab.net>
