On the @Forgejo instance of Codeberg, we discovered that forking a repo
which is already forked now returns a 500 Internal Server Error, which
is unexpected. This is an attempt at fixing this.
The error message in the log:
~~~
2023/05/02 08:36:30 .../api/v1/repo/fork.go:147:CreateFork() [E]
[6450cb8e-113] ForkRepository: repository is already forked by user
[uname: ...., repo path: .../..., fork path: .../...]
~~~
The service that is used for forking returns a custom error message
which is not checked against.
About the order of options:
The case that the fork already exists should be more common, followed by
the case that a repo with the same name already exists for other
reasons. The case that the global repo limit is hit is probably not the
likeliest.

The old `HTMLRender` is not ideal.
1. It shouldn't be initialized multiple times, it consumes a lot of
memory and is slow.
2. It shouldn't depend on short-lived requests, the `WatchLocalChanges`
needs a long-running context.
3. It doesn't make sense to use FuncsMap slice.
HTMLRender was designed to only work for GItea's specialized 400+
templates, so it's good to make it a global shared instance.
For my specific use case, I'd like to get all commits that are on one
branch but NOT on the other branch.
For instance, I'd like to get all the commits on `Branch1` that are not
also on `master` (I.e. all commits that were made after `Branch1` was
created).
This PR adds a `not` query param that gets passed down to the `git log`
command to allow the user to exclude items from `GetAllCommits`.

There was only one `IsRepositoryExist` function, it did: `has && isDir`
However it's not right, and it would cause 500 error when creating a new
repository if the dir exists.
Then, it was changed to `has || isDir`, it is still incorrect, it
affects the "adopt repo" logic.

This adds a API for getting License templates. This tries to be as close
to the [GitHub
API](https://docs.github.com/en/rest/licenses?apiVersion=2022-11-28) as
possible, but Gitea does not support all features that GitHub has. I
think they should been added, but this out f the scope of this PR. You
should merge #23006 before this PR for security reasons.
The old code is unnecessarily complex, and has many misuses.
Old code "wraps" a lot, wrap wrap wrap, it's difficult to understand
which kind of handler is used.
The new code uses a general approach, we do not need to write all kinds
of handlers into the "wrapper", do not need to wrap them again and
again.
New code, there are only 2 concepts:
1. HandlerProvider: `func (h any) (handlerProvider func (next)
http.Handler)`, it can be used as middleware
2. Use HandlerProvider to get the final HandlerFunc, and use it for
`r.Get()`
And we can decouple the route package from context package (see the
TODO).
# FAQ
## Is `reflect` safe?
Yes, all handlers are checked during startup, see the `preCheckHandler`
comment. If any handler is wrong, developers could know it in the first
time.
## Does `reflect` affect performance?
No. https://github.com/go-gitea/gitea/pull/24080#discussion_r1164825901
1. This reflect code only runs for each web handler call, handler is far
more slower: 10ms-50ms
2. The reflect is pretty fast (comparing to other code): 0.000265ms
3. XORM has more reflect operations already
Close#24195
Some of the changes are taken from my another fix
f07b0de997
in #20147 (although that PR was discarded ....)
The bug is:
1. The old code doesn't handle `removedfile` event correctly
2. The old code doesn't provide attachments for type=CommentTypeReview
This PR doesn't intend to refactor the "upload" code to a perfect state
(to avoid making the review difficult), so some legacy styles are kept.

1. Clearly define the wiki path behaviors, see
`services/wiki/wiki_path.go` and tests
2. Keep compatibility with old contents
3. Allow to use dashes in titles, eg: "2000-01-02 Meeting record"
4. Add a "Pages" link in the dropdown, otherwise users can't go to the
Pages page easily.
5. Add a "View original git file" link in the Pages list, even if some
file names are broken, users still have a chance to edit or remove it,
without cloning the wiki repo to local.
6. Fix 500 error when the name contains prefix spaces.
This PR also introduces the ability to support sub-directories, but it
can't be done at the moment due to there are a lot of legacy wiki data,
which use "%2F" in file names.

The name of the job or step comes from the workflow file, while the name
of the runner comes from its registration. If the strings used for these

This includes pull requests that you approved, requested changes or
commented on. Currently such pull requests are not visible in any of the
filters on /pulls, while they may need further action like merging, or
prodding the author or reviewers.
Especially when working with a large team on a repository it's helpful
to get a full overview of pull requests that may need your attention,
without having to sift through the complete list.

- It also renames all functions in setting from `newXXXService` to

- Move `XORMLog` to `SQLLog` because it's a better name for that.

Add a new "exclusive" option per label. This makes it so that when the
label is named `scope/name`, no other label with the same `scope/`
prefix can be set on an issue.
The scope is determined by the last occurence of `/`, so for example
`scope/alpha/name` and `scope/beta/name` are considered to be in
different scopes and can coexist.
Exclusive scopes are not enforced by any database rules, however they
are enforced when editing labels at the models level, automatically
removing any existing labels in the same scope when either attaching a
new label or replacing all labels.
In menus use a circle instead of checkbox to indicate they function as
radio buttons per scope. Issue filtering by label ensures that only a
single scoped label is selected at a time. Clicking with alt key can be
used to remove a scoped label, both when editing individual issues and
batch editing.
Label rendering refactor for consistency and code simplification:
* Labels now consistently have the same shape, emojis and tooltips
everywhere. This includes the label list and label assignment menus.
* In label list, show description below label same as label menus.
* Don't use exactly black/white text colors to look a bit nicer.
* Simplify text color computation. There is no point computing luminance
in linear color space, as this is a perceptual problem and sRGB is
closer to perceptually linear.
* Increase height of label assignment menus to show more labels. Showing
only 3-4 labels at a time leads to a lot of scrolling.
* Render all labels with a new RenderLabel template helper function.
Label creation and editing in multiline modal menu:
* Change label creation to open a modal menu like label editing.
* Change menu layout to place name, description and colors on separate
lines.
* Don't color cancel button red in label editing modal menu.
* Align text to the left in model menu for better readability and
consistent with settings layout elsewhere.
Custom exclusive scoped label rendering:
* Display scoped label prefix and suffix with slightly darker and
lighter background color respectively, and a slanted edge between them
similar to the `/` symbol.
* In menus exclusive labels are grouped with a divider line.

Allow back-dating user creation via the `adminCreateUser` API operation.
`CreateUserOption` now has an optional field `created_at`, which can
contain a datetime-formatted string. If this field is present, the
user's `created_unix` database field will be updated to its value.
This is important for Blender's migration of users from Phabricator to
Gitea. There are many users, and the creation timestamp of their account
can give us some indication as to how long someone's been part of the
community.
The back-dating is done in a separate query that just updates the user's
`created_unix` field. This was the easiest and cleanest way I could
find, as in the initial `INSERT` query the field always is set to "now".
To avoid duplicated load of the same data in an HTTP request, we can set
a context cache to do that. i.e. Some pages may load a user from a
database with the same id in different areas on the same page. But the
code is hidden in two different deep logic. How should we share the
user? As a result of this PR, now if both entry functions accept
`context.Context` as the first parameter and we just need to refactor
`GetUserByID` to reuse the user from the context cache. Then it will not
be loaded twice on an HTTP request.
But of course, sometimes we would like to reload an object from the
database, that's why `RemoveContextData` is also exposed.
The core context cache is here. It defines a new context
```go
type cacheContext struct {
ctx context.Context
data map[any]map[any]any
lock sync.RWMutex
}
var cacheContextKey = struct{}{}
func WithCacheContext(ctx context.Context) context.Context {
return context.WithValue(ctx, cacheContextKey, &cacheContext{
ctx: ctx,
data: make(map[any]map[any]any),
})
}
```
Then you can use the below 4 methods to read/write/del the data within
the same context.
```go
func GetContextData(ctx context.Context, tp, key any) any
func SetContextData(ctx context.Context, tp, key, value any)
func RemoveContextData(ctx context.Context, tp, key any)
func GetWithContextCache[T any](ctx context.Context, cacheGroupKey string, cacheTargetID any, f func() (T, error)) (T, error)
```
Then let's take a look at how `system.GetString` implement it.
```go
func GetSetting(ctx context.Context, key string) (string, error) {
return cache.GetWithContextCache(ctx, contextCacheKey, key, func() (string, error) {
return cache.GetString(genSettingCacheKey(key), func() (string, error) {
res, err := GetSettingNoCache(ctx, key)
if err != nil {
return "", err
}
return res.SettingValue, nil
})
})
}
```
First, it will check if context data include the setting object with the
key. If not, it will query from the global cache which may be memory or
a Redis cache. If not, it will get the object from the database. In the
end, if the object gets from the global cache or database, it will be
set into the context cache.
An object stored in the context cache will only be destroyed after the
context disappeared.
Add setting to allow edits by maintainers by default, to avoid having to
often ask contributors to enable this.
This also reorganizes the pull request settings UI to improve clarity.
It was unclear which checkbox options were there to control available
merge styles and which merge styles they correspond to.
Now there is a "Merge Styles" label followed by the merge style options
with the same name as in other menus. The remaining checkboxes were
moved to the bottom, ordered rougly by typical order of operations.

This PR implements the mapping of user groups provided by OIDC providers
to orgs teams in Gitea. The main part is a refactoring of the existing
LDAP code to make it usable from different providers.
Refactorings:
- Moved the router auth code from module to service because of import
cycles
- Changed some model methods to take a `Context` parameter
- Moved the mapping code from LDAP to a common location
I've tested it with Keycloak but other providers should work too. The
JSON mapping format is the same as for LDAP.

The `commit_id` property name is the same as equivalent functionality in
GitHub. If the action was not caused by a commit, an empty string is
used.
This can for example be used to automatically add a Resolved label to an
issue fixed by a commit, or clear it when the issue is reopened.
This PR adds the support for scopes of access tokens, mimicking the
design of GitHub OAuth scopes.
The changes of the core logic are in `models/auth` that `AccessToken`
struct will have a `Scope` field. The normalized (no duplication of
scope), comma-separated scope string will be stored in `access_token`
table in the database.
In `services/auth`, the scope will be stored in context, which will be
used by `reqToken` middleware in API calls. Only OAuth2 tokens will have
granular token scopes, while others like BasicAuth will default to scope
`all`.
A large amount of work happens in `routers/api/v1/api.go` and the
corresponding `tests/integration` tests, that is adding necessary scopes
to each of the API calls as they fit.
- [x] Add `Scope` field to `AccessToken`
- [x] Add access control to all API endpoints
- [x] Update frontend & backend for when creating tokens
- [x] Add a database migration for `scope` column (enable 'all' access
to past tokens)
I'm aiming to complete it before Gitea 1.19 release.

- Redesign `RemoveIDFromList([]int64, int64) ([]int64, bool)` to
`SliceRemoveAll[T]([]T, T) []T`.
- Add `SliceContainsFunc[T]([]T, func(T) bool)` and

SessionStore) (*user_model.User, error)`.
There is a new return argument `error` which means the verification
condition matched but verify process failed, we should stop the auth
process.
Before this PR, when return a `nil` user, we don't know the reason why
it returned `nil`. If the match condition is not satisfied or it
verified failure? For these two different results, we should have
different handler. If the match condition is not satisfied, we should
try next auth method and if there is no more auth method, it's an
anonymous user. If the condition matched but verify failed, the auth
process should be stop and return immediately.

Since we changed the /api/v1/ routes to disallow session authentication
we also removed their reliance on CSRF. However, we left the
ReverseProxy authentication here - but this means that POSTs to the API
are no longer protected by CSRF.
Now, ReverseProxy authentication is a kind of session authentication,
and is therefore inconsistent with the removal of session from the API.
This PR proposes that we simply remove the ReverseProxy authentication
from the API and therefore users of the API must explicitly use tokens
or basic authentication.
