Mihir Joshi 62f2d717b7 Fix reverting a merge commit failing (#28794) (#28825) ... Backport https://github.com/go-gitea/gitea/pull/28794 Fixes #22236 --- Error occurring currently while trying to revert commit using read-tree -m approach: > 2022/12/26 16:04:43 ...rvices/pull/patch.go:240:AttemptThreeWayMerge() [E] [63a9c61a] Unable to run read-tree -m! Error: exit status 128 - fatal: this operation must be run in a work tree > - fatal: this operation must be run in a work tree We need to clone a non-bare repository for `git read-tree -m` to work. bb371aee6e adds support to create a non-bare cloned temporary upload repository. After cloning a non-bare temporary upload repository, we [set default index](https://github.com/go-gitea/gitea/blob/main/services/repository/files/cherry_pick.go#L37) (`git read-tree HEAD`). This operation ends up resetting the git index file (see investigation details below), due to which, we need to call `git update-index --refresh` afterward. Here's the diff of the index file before and after we execute SetDefaultIndex: https://www.diffchecker.com/hyOP3eJy/ Notice the **ctime**, **mtime** are set to 0 after SetDefaultIndex. You can reproduce the same behavior using these steps: ```bash $ git clone https://try.gitea.io/me-heer/test.git -s -b main $ cd test $ git read-tree HEAD $ git read-tree -m 1f085d7ed8 1f085d7ed8 9933caed00 error: Entry '1' not uptodate. Cannot merge. ``` After which, we can fix like this: ```bash $ git update-index --refresh $ git read-tree -m 1f085d7ed8 1f085d7ed8 9933caed00 ```		2024-01-21 14:18:37 +00:00
