* plumbing: commitgraph, allow SHA256 commit-graphsAndrew Thornton2023-09-302-13/+31
| | | | | | | | Since the build-tag sha256 was introduced the commit graph code should be switched to use hash.Size and only use a graph if it has the correct hash version for the version of go-git that is built. Signed-off-by: Andrew Thornton <art27@cantab.net>
* *: Support variable length plumbing.HashPaulo Gomes2023-03-081-4/+3
| | | | | | | | | | | | 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>
* sha1: Add collision resistent implementationPaulo Gomes2022-11-251-3/+3
| | | | | | | | | | | | | | | | | | | 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>
* error strings: Don't capitalize, use periods, or newlinesAbhinav Gupta2021-12-041-3/+3
| | | | | | | | | | | | | | | | | | | | | Per [Go Code Review Comments][1], > Error strings should not be capitalized (unless beginning with proper > nouns or acronyms) or end with punctuation staticcheck's [ST1005][2] also complains about these. 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.
