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 1f085d7ed81f085d7ed89933caed00
error: Entry '1' not uptodate. Cannot merge.
```
After which, we can fix like this:
```bash
$ git update-index --refresh
$ git read-tree -m 1f085d7ed81f085d7ed89933caed00
```
tests: missing refs/ in bare repositories (#28844) (#28852)
Backport #28844 by @AdamMajer
Git 2.43.0 will not detect a git repository as valid without refs/
subdirectory present. `git gc` cleans this up and puts it in
packed-refs. We must keep refs/ non-empty.

Fix #25558
Extract from #22743
This PR added a repository's check when creating/deleting branches via
API. Mirror repository and archive repository cannot do that.
Substitute variables in path names of template repos too (#25294)
### Summary
Extend the template variable substitution to replace file paths. This
can be helpful for setting up log files & directories that should match
the repository name.
### PR Changes
- Move files matching glob pattern when setting up repos from template
- For security, added ~escaping~ sanitization for cross-platform support
and to prevent directory traversal (thanks @silverwind for the
reference)
- Added unit testing for escaping function
- Fixed the integration tests for repo template generation by passing
the repo_template_id
- Updated the integration testfiles to add some variable substitution &
assert the outputs
I had to fix the existing repo template integration test and extend it
to add a check for variable substitutions.
Example:
Replace `repo.namedBlob` by `git.TreeEntry`. (#22898)
`namedBlob` turned out to be a poor imitation of a `TreeEntry`. Using
the latter directly shortens this code.
This partially undoes https://github.com/go-gitea/gitea/pull/23152/,
which I found a merge conflict with, and also expands the test it added
to cover the subtle README-in-a-subfolder case.
Add test coverage to the important features of
[`routers.web.repo.renderReadmeFile`](067b0c2664/routers/web/repo/view.go (L273);)
namely that:
- it can handle looking in docs/, .gitea/, and .github/
- it can handle choosing between multiple competing READMEs
- it prefers the localized README to the markdown README to the
plaintext README
- it can handle broken symlinks when processing all the options
- it uses the name of the symlink, not the name of the target of the
symlink
Use correct README link to render the README (#23152)
`renderReadmeFile` needs `readmeTreelink` as parameter but gets
`treeLink`.
The values of them look like as following:
`treeLink`: `/{OwnerName}/{RepoName}/src/branch/{BranchName}`
`readmeTreelink`:
`/{OwnerName}/{RepoName}/src/branch/{BranchName}/{ReadmeFileName}`
`path.Dir` in
8540fc45b1/routers/web/repo/view.go (L316)
should convert `readmeTreelink` into
`/{OwnerName}/{RepoName}/src/branch/{BranchName}` instead of the current
`/{OwnerName}/{RepoName}/src/branch`.
Fixes #23151
