| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | plumbing: support SSH/X509 signed tagsHidde Beydals2023-02-274-32/+307
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit enables support for extracting the SSH and X509 signatures from (annotated) Git tags, as an initial step to support the verification of more signatures than just PGP in go-git. The ported logic from Git further ensures that we look for a signature at the tail of an annotation, instead of the first signature we find in the annotation, as this could theoretically result in a faulty signature getting detected if part of a an annotation itself (e.g. by being placed in the middle as part of an inherited message). For commits, no further change is required as the current extraction of any signature (format) from `gpgsig` in the commit header is sufficient for manual verification. In a future iteration, we could add `signature/ssh` and `signature/x509` packages to further enable people to deal with verifying other signatures than PGP. As well as adding additional methods to `Commit` and `Tag` to provide glue between the packages and the most prominent user-facing APIs. Signed-off-by: Hidde Beydals <hidde@hhh.computer>
* / Remove need to build with CGOPaulo Gomes2023-02-251-4/+2
|/ | | | | | | | | | | | Follow-up from #618, at the time the Pure Go sha1cd implementation was not performant enough to be the default. This has now changed and the cgo and generic implementations yields similar results. Users are able to override the default implementation, however this seems to be a better default as it does not require the use of CGO during build time. Signed-off-by: Paulo Gomes <pjbgf@linux.com>
* sha1: Add collision resistent implementationPaulo Gomes2022-11-258-17/+181
| | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Azure DevOps requires capabilities multi_ack / multi_ack_detailed, which are not fully implemented and by default are included in transport.UnsupportedCapabilities. The initial clone operations require a full download of the repository, and therefore those unsupported capabilities are not as crucial, so by removing them from that list allows for the first clone to work successfully. Additional fetches will yield issues, therefore to support that repository users have to work from a clean clone until those capabilities are fully supported. Commits and pushes back into the repository have also been tested and work fine. This change adds an example for cloning Azure DevOps repositories. Signed-off-by: Paulo Gomes <pjbgf@linux.com>

One additional allocation has been removed by using its own implementation of Strings(). The reason behind this was due to the fact the calls to .String() are more recurrent than .Strings() and the performance impact was worth the code duplication.

The algorithms are chosen based on the known host keys for the target host, as obtained from the known_hosts file. In order to look-up the algorithms from the known_hosts file, external module github.com/skeema/knownhosts is used. This package is just a thin wrapper around golang.org/x/crypto/ssh/knownhosts, adding an extra mechanism to query the known_hosts keys, implemented in a way which avoids duplication of any golang.org/x/crypto/ssh/knownhosts logic. Because HostKeyAlgorithms vary by target host, some related logic for setting HostKeyCallback has been moved out of the various AuthMethod implementations. This was necessary because the old HostKeyCallbackHelper is not host-specific. Since known_hosts handling isn't really tied to AuthMethod anyway, it seems reasonable to separate these. Previously-exported types/methods remain in place for backwards compat, but some of them are now unused. For testing approach, see pull request. Issue #411 can only be reproduced via end-to-end / integration testing, since it requires actually launching an SSH connection, in order to see the key mismatch error triggered from https://github.com/golang/go/issues/29286 as the root cause.

(#521) Previously, calling `Set($CAPABILITY, ...)` on a `capability.List` where `$CAPABILITY` was already present would correctly replace the existing value of that capability, but would also result in that capability being listed twice in the internal `l.sort` slice. This manifested publicly when the `List` was encoded as the same capability appearing twice with the same value in the encoded output.

Baz = ... ) This means that `packp.{Update, Delete, Invalid}` are currently untyped string constants, and not `Action` constants as was intended here. This change fixes these.
