Resolve #31609
This PR was initiated following my personal research to find the
lightest possible Single Sign-On solution for self-hosted setups. The
existing solutions often seemed too enterprise-oriented, involving many
moving parts and services, demanding significant resources while
promising planetary-scale capabilities. Others were adequate in
supporting basic OAuth2 flows but lacked proper user management
features, such as a change password UI.
Gitea hits the sweet spot for me, provided it supports more granular
access permissions for resources under users who accept the OAuth2
application.
This PR aims to introduce granularity in handling user resources as
nonintrusively and simply as possible. It allows third parties to inform
users about their intent to not ask for the full access and instead
request a specific, reduced scope. If the provided scopes are **only**
the typical ones for OIDC/OAuth2—`openid`, `profile`, `email`, and
`groups`—everything remains unchanged (currently full access to user's
resources). Additionally, this PR supports processing scopes already
introduced with [personal
tokens](https://docs.gitea.com/development/oauth2-provider#scopes) (e.g.
`read:user`, `write:issue`, `read:group`, `write:repository`...)
Personal tokens define scopes around specific resources: user info,
repositories, issues, packages, organizations, notifications,
miscellaneous, admin, and activitypub, with access delineated by read
and/or write permissions.
The initial case I wanted to address was to have Gitea act as an OAuth2
Identity Provider. To achieve that, with this PR, I would only add
`openid public-only` to provide access token to the third party to
authenticate the Gitea's user but no further access to the API and users
resources.
Another example: if a third party wanted to interact solely with Issues,
it would need to add `read:user` (for authorization) and
`read:issue`/`write:issue` to manage Issues.
My approach is based on my understanding of how scopes can be utilized,
supported by examples like [Sample Use Cases: Scopes and
Claims](https://auth0.com/docs/get-started/apis/scopes/sample-use-cases-scopes-and-claims)
on auth0.com.
I renamed `CheckOAuthAccessToken` to `GetOAuthAccessTokenScopeAndUserID`
so now it returns AccessTokenScope and user's ID. In the case of
additional scopes in `userIDFromToken` the default `all` would be
reduced to whatever was asked via those scopes. The main difference is
the opportunity to reduce the permissions from `all`, as is currently
the case, to what is provided by the additional scopes described above.

protection rules that prevents admins/repo owners from bypassing branch
protection rules and merging without approvals or failing status checks.

This PR do some minor improvements for head branch display on pull
request view UI.
- [x] Remove the link if the head branch has been deleted with a
tooltip, so that users will not result in a 404 page
- [x] Display a label if this pull request is an agit based one.
A regression in #31924 caused there to be two `issues.review.comment`
keys in the English language locale file, leading to a problem when
reading PR review histories that contain comments.
This snapshot addresses this by making the newer key unique.
Remove unused CSRF options, decouple "new csrf protector" and "prepare"
logic, do not redirect to home page if CSRF validation falis (it
shouldn't happen in daily usage, if it happens, redirecting to home
doesn't help either but just makes the problem more complex for "fetch")
Follow #31950 and Fix the display bug of #31966 .
This will only fix the English version. I will update all these
translation files in crowdin after this merged so that all the languages
can be fixed.
And all these files should be backported together.
This PR remove the bold effect around the name when creating a new tag
or branch.
Part of #27700
Removes all URLs from translation strings to easy up changing them in
the future and to exclude people injecting malicious URLs through
translations. First measure as long as #24402 is out of scope.
