There was a problem hiding this comment.
When a page contains many commits with large changed-file lists, the 64 MiB limit applies independently to each load_changes invocation while every resulting JSON object remains in items. With the allowed 50-commit page, one request can retain over 3 GiB before serialization creates another large buffer, so a repository crafted with large trees can exhaust the forge process despite the advertised bounded reads. Apply a request-wide response/change budget rather than only a per-git-process cap.

There was a problem hiding this comment.
When a parent commit has a different committer timestamp from its child, this assigns the child's timestamp to the parent's created field; merge commits also report the same time for every parent. API consumers therefore receive incorrect commit metadata, so each parent timestamp should be loaded from that parent rather than reusing c.committer.when.

When a tree contains a gitlink with a corresponding entry in .gitmodules, the response identifies it as type: "submodule" but always returns submodule_git_url: null. This drops the remote URL that Gitea-compatible clients use to identify or clone the submodule; resolve the matching .gitmodules URL at the selected commit and return it for gitlinks.

There was a problem hiding this comment.
When an explicitly supplied revision contains malformed UTF-8 percent encoding, such as ?ref=%FF or ?sha=%FF, percent_decode returns None and this helper makes it indistinguishable from an absent parameter. The contents and commits handlers then serve the default branch with a successful response rather than rejecting the requested revision, which can make clients consume unrelated content. Preserve the distinction between missing and invalid parameters and return a client error for the latter.

When a valid lightweight tag points directly to a tree or blob, for-each-ref reports its type as tree or blob, but this branch sends every non-annotated-tag object to /git/commits/{oid}. The returned ref therefore contains a URL that cannot resolve that object—for example, a tree tag links to the commit endpoint instead of /git/trees/{oid}. Select the URL segment from r.kind, not only from whether it equals tag.

There was a problem hiding this comment.
When a pushed branch or tag contains a URL-reserved character that Git permits, such as release#1 or a literal %2F, this inserts the raw ref name into the top-level URL. Following that URL either drops the fragment or decodes the percent sequence into a different path, so the advertised self-link does not retrieve the listed ref. Percent-encode each ref-name path segment before constructing the URL, as the contents and archive links already do.

Opus and Sol reviews of the F3a diff fixed; Codex and CodeRabbit findings triaged; required checks green on 18aece9.

Opus and Sol both reviewed the diff. Fixed:
.patchof a merge returned another commit's patch; the archive memory bound did not hold (the runner permit ends with the git process); symlink targets could be read without limit; an unborn default hid an explicitly named branch; the Link header could switch branches on a repeated parameter;not=was silently ignored (now 400); docs that did not match the code.
