Backport #22611
The code for checking if a commit has caused a change in a PR is
extremely inefficient and affects the head repository instead of using a
temporary repository.
This PR therefore makes several significant improvements:
* A temporary repo like that used in merging.
* The diff code is then significant improved to use a three-way diff
instead of comparing diffs (possibly binary) line-by-line - in memory...

Backport #22535
The update by rebase code reuses the merge code but shortcircuits and
pushes back up to the head. However, it doesn't set the correct pushing
environment - and just uses the same environment as the base repo. This
leads to the push update failing and thence the PR becomes out-of-sync
with the head.
This PR fixes this and adjusts the trace logging elsewhere to help make
this clearer.

Backport #22130
For a long time Gitea has tested PR patches using a git apply --check
method, and in fact prior to the introduction of a read-tree assisted
three-way merge in #18004, this was the only way of checking patches.
Since #18004, the git apply --check method has been a fallback method,
only used when the read-tree three-way merge method has detected a
conflict. The read-tree assisted three-way merge method is much faster
and less resource intensive method of detecting conflicts. #18004 kept
the git apply method around because it was thought possible that this
fallback might be able to rectify conflicts that the read-tree three-way
merge detected. I am not certain if this could ever be the case.
Given the uncertainty here and the now relative stability of the
read-tree method - this PR makes using this fallback optional but
enables it by default. A `log.Critical` has been added which will alert
if the `git apply --check` method was successful at checking a PR that
`read-tree` failed on.
The hope is that none of these log.Critical messages will be found and
there will be no significant difference in conflict detection. Thus we
will be able to remove the git apply fallback in future, and/or improve
the read-tree three-way merge method to catch any conflicts that git
apply method might have been able to fix.
An additional benefit for anyone who disables the check method is that
patch checking should be significantly less resource intensive and much
quicker.

Moved files in a patch will result in git apply returning:
```
error: {filename}: No such file or directory
```
This wasn't handled by the git apply patch code. This PR adds handling
for this.

When merge was changed to run in the background context, the db updates
were still running in request context. This means that the merge could
be successful but the db not be updated.
This PR changes both these to run in the hammer context, this is not
complete rollback protection but it's much better.

Some repositories do not have the PullRequest unit present in their configuration
and unfortunately the way that IsUserAllowedToUpdate currently works assumes
that this is an error instead of just returning false.
This PR simply swallows this error allowing the function to return false.

There is a subtle bug in the code relating to collating the results of
`git ls-files -u -z` in `unmergedFiles()`. The code here makes the
mistake of assuming that every unmerged file will always have a stage 1
conflict, and this results in conflicts that occur in stage 3 only being
dropped.
This PR simply adjusts this code to ensure that any empty unmergedFile
will always be passed down the channel.
The PR also adds a lot of Trace commands to attempt to help find future
bugs in this code.

Adds a feature [like GitHub has](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request-from-a-fork) (step 7).
If you create a new PR from a forked repo, you can select (and change later, but only if you are the PR creator/poster) the "Allow edits from maintainers" option.
Then users with write access to the base branch get more permissions on this branch:
* use the update pull request button
* push directly from the command line (`git push`)
* edit/delete/upload files via web UI
* use related API endpoints
You can't merge PRs to this branch with this enabled, you'll need "full" code write permissions.
This feature has a pretty big impact on the permission system. I might forgot changing some things or didn't find security vulnerabilities. In this case, please leave a review or comment on this PR.
Closes#17728
Co-authored-by: 6543 <6543@obermui.de>
This gets the necessary data to the issuelist for it to support a clickable commit status icon which pops up the full list of commit statuses related to the commit. It accomplishes this without any additional queries or fetching as the existing codepath was already doing the necessary work but only returning the "last" status. All methods were wrapped to call the least-filtered version of each function in order to maximize code reuse.
Note that I originally left `getLastCommitStatus()` in `pull.go` which called to the new function, but `make lint` complained that it was unused, so I removed it. I would have preferred to keep it, but alas.
The only thing I'd still like to do here is force these popups to happen to the right by default instead of the left. I see that the only other place this is popping up right is on view_list.tmpl, but I can't figure out how/why right now.
Fixes#18810
* Set correct PR status on 3way on conflict checking
- When 3-way merge is enabled for conflict checking, it has a new
interesting behavior that it doesn't return any error when it found a
conflict, so we change the condition to not check for the error, but
instead check if conflictedfiles is populated, this fixes a issue
whereby PR status wasn't correctly on conflicted PR's.
- Refactor the mergeable property(which was incorrectly set and lead me this
bug) to be more maintainable.
- Add a dedicated test for conflicting checking, so it should prevent
future issues with this.
* Fix linter
* Don't allow merging PR's which are being conflict checked
- When a PR is still being conflict checked, don't allow the PR to be
merged(the merge button could already be visible before e.g. a new
commit was pushed to the PR).
- Relevant(should prevent such issue from happening) #19352

Follows #19266, #8553, Close#18553, now there are only three `Run..(&RunOpts{})` functions.
* before: `stdout, err := RunInDir(path)`
* now: `stdout, _, err := RunStdString(&git.RunOpts{Dir:path})`
Continues on from #19202.
Following the addition of pprof labels we can now more easily understand the relationship between a goroutine and the requests that spawn them.
This PR takes advantage of the labels and adds a few others, then provides a mechanism for the monitoring page to query the pprof goroutine profile.
The binary profile that results from this profile is immediately piped in to the google library for parsing this and then stack traces are formed for the goroutines.
If the goroutine is within a context or has been created from a goroutine within a process context it will acquire the process description labels for that process.
The goroutines are mapped with there associate pids and any that do not have an associated pid are placed in a group at the bottom as unbound.
In this way we should be able to more easily examine goroutines that have been stuck.
A manager command `gitea manager processes` is also provided that can export the processes (with or without stacktraces) to the command line.

This make checks in one single place so they dont differ and maintainer can not forget a check in one place while adding it to the other .... ( as it's atm )
Fix:
* The API does ignore issue dependencies where Web does not
* The API checks if "IsSignedIfRequired" where Web does not - UI probably do but nothing will some to craft custom requests
* Default merge message is crafted a bit different between API and Web if not set on specific cases ...
There is yet another problem with conflicted files not being reset when
the test patch resolves them.
This PR adjusts the code for checkConflicts to reset the ConflictedFiles
field immediately at the top. It also adds a reset to conflictedFiles

This code adds a simple endpoint to apply patches to repositories and
branches on gitea. This is then used along with the conflicting checking
code in #18004 to provide a basic implementation of cherry-pick revert.
Now because the buttons necessary for cherry-pick and revert have
required us to create a dropdown next to the Browse Source button
I've also implemented Create Branch and Create Tag operations.
