- When specifying push options, tooling like [git-repo-go](https://github.com/alibaba/git-repo-go) encodes pushoption values if they contain newlines or non-ASCII characters as they cannot be easily specified via the CLI otherwise. - Recognize such base64 encoded values in the pushoptions (those that have the `{base64}` prefix), if the base64 decoding fails we return the original value. - Resolves forgejo/forgejo#8161 <!--start release-notes-assistant--> ## Release notes <!--URL:https://codeberg.org/forgejo/forgejo--> - Features - [PR](https://codeberg.org/forgejo/forgejo/pulls/8479): <!--number 8479 --><!--line 0 --><!--description QUdpdCBwdXNoIG9wdGlvbnMgc3RhcnRpbmcgd2l0aCBge2Jhc2U2NH1gIGFyZSBkZWNvZGVk-->AGit push options starting with `{base64}` are decoded<!--description--> <!--end release-notes-assistant--> Reviewed-on: https://codeberg.org/forgejo/forgejo/pulls/8479 Reviewed-by: Earl Warren <earl-warren@noreply.codeberg.org> Co-authored-by: Gusted <postmaster@gusted.xyz> Co-committed-by: Gusted <postmaster@gusted.xyz>
