A remote user (UserTypeRemoteUser) is a placeholder that can be
promoted to a regular user (UserTypeIndividual). It represents users
that exist somewhere else. Although the UserTypeRemoteUser already
exists in Forgejo, it is neither used or documented.
A new login type / source (Remote) is introduced and set to be the login type
of remote users.
Type UserTypeRemoteUser
LogingType Remote
The association between a remote user and its counterpart in another
environment (for instance another forge) is via the OAuth2 login
source:
LoginName set to the unique identifier relative to the login source
LoginSource set to the identifier of the remote source
For instance when migrating from GitLab.com, a user can be created as
if it was authenticated using GitLab.com as an OAuth2 authentication
source.
When a user authenticates to Forejo from the same authentication
source and the identifier match, the remote user is promoted to a
regular user. For instance if 43 is the ID of the GitLab.com OAuth2
login source, 88 is the ID of the Remote loging source, and 48323
is the identifier of the foo user:
Type UserTypeRemoteUser
LogingType Remote
LoginName 48323
LoginSource 88
Email (empty)
Name foo
Will be promoted to the following when the user foo authenticates to
the Forgejo instance using GitLab.com as an OAuth2 provider. All users
with a LoginType of Remote and a LoginName of 48323 are examined. If
the LoginSource has a provider name that matches the provider name of
GitLab.com (usually just "gitlab"), it is a match and can be promoted.
The email is obtained via the OAuth2 provider and the user set to:
Type UserTypeIndividual
LogingType OAuth2
LoginName 48323
LoginSource 43
Email foo@example.com
Name foo
Note: the Remote login source is an indirection to the actual login
source, i.e. the provider string my be set to a login source that does
not exist yet.
Add a new member to `DeclarativeRepoOptions`: `WikiBranch`. If
specified, create a Wiki with the given branch, and a single "Home"

Lets introduce a new helper function,
`CreateDeclarativeRepoWithOptions`! This is almost the same as the
existing `CreateDeclarativeRepo` helper, but instead of taking a list of
random parameters the author thought of at the time of its introduction,
it takes a `DeclarativeRepoOptions` struct, with optional members.
This makes it easier to extend the function, as new members can be added
without breaking or having to update existing callsites, as long as the
newly added members default to compatible values.
`CreateDeclarativeRepo` is then reimplemented on top of the new
function. Callsites aren't updated yet, we can do that organically,
whenever touching code that uses the older function.
No new functionality is introduced just yet, this is merely a refactor.

Conflict resolved by manually adding the lines from the Gitea
PR.
It is possible to change some repo settings (its visibility, and
template status) via `git push` options: `-o repo.private=true`, `-o
repo.template=true`.
Previously, there weren't sufficient permission checks on these, and
anyone who could `git push` to a repository - including via an AGit
workflow! - was able to change either of these settings. To guard
against this, the pre-receive hook will now check if either of these
options are present, and if so, will perform additional permission
checks to ensure that these can only be set by a repository owner or
an administrator. Additionally, changing these settings is disabled for
forks, even for the fork's owner.
There's still a case where the owner of a repository can change the
visibility of it, and it will not propagate to forks (it propagates to
forks when changing the visibility via the API), but that's an
inconsistency, not a security issue.

I kept @zareck 's commit as is, because I believe it is correct. We can't move the check to `owner.CanForkRepo()`, because `owner` is the future owner of the forked repo, and may be an organization. We need to check the admin permission of the `doer`, like in the case of repository creation.
I verified that the test fails without the `ForkRepository` change, and passes with it.

* commit C is pushed
* the git hook queues AddTestPullRequestTask for processing and returns with success
* TestPullRequest is not called yet
* a pull request P with commit C as the head is created
* TestPullRequest runs and ignores P because it was created after the commit was received

The fix against the race incorrectly assumes the sha of the commit being
pushed belongs to the base repository. It finds the highest possible
pull request ID from the head repository instead of looking it up in
the base repository.
Figuring out if a PR was created in the future based on the highest
index of the base repository would require collecting all of them
because there is no way to know in advance which repository may be
involved in the race.
Fixing this race can be done either by:
* Introducing a new field in the pull_request table https://codeberg.org/forgejo/forgejo/pulls/2842
which feels more like a hack than a real solution
* Refactoring the logic
which would be a significant undertaking
The race has been in the codebase for a very long time and manifests
itself in the CI, when events happen in quick succession. The only
concrete manifestation was however fixed by https://codeberg.org/forgejo/forgejo/issues/2009

inconsistencies within Forgejo and lead to internal server errors when
trying access the pull request, this action should be reserved for

shields.io uses dashes to separate parts of the badge it needs to
return. If our label or text parts contain dashes, we need to encode
those for shields.io to recognise what we want it to do, and to have the
correct text on the badge, too.
Fortunately, this is as simple as replacing all dashes with double
dashes in both the label and the text parts. We do not need to do the
same for the color, because that part is not user controlled.
This fixes the badges for cases when a workflow name includes dashes, or
when a release's tag name does.

case some users would like to find a target user in the search result,
the "sort order" might help.

The problem is the check in `CatFileBatch`:
79217ea63c/modules/git/repo_base_nogogit.go (L81-L87)
`Buffered() > 0` is used to check if there is a "operation" in progress
at the moment. This is a problem because we can't control the internal
buffer in the `bufio.Reader`. The code above demonstrates a sequence
which initiates an operation for which the code thinks there is no
active processing. The second call to `DataAsync()` therefore reuses the
existing instances instead of creating a new batch reader.
