This allows for usernames, and emails connected to them to be reserved
and not reused.
Use case, I manage an instance with open registration, and sometimes
when users are deleted for spam (or other purposes), their usernames are
freed up and they sign up again with the same information.
This could also be used to reserve usernames, and block them from being
registered (in case an instance would like to block certain things
without hardcoding the list in code and compiling from scratch).
This is an MVP, that will allow for future work where you can set
something as reserved via the interface.

Close #24062
At the beginning, I just wanted to fix the warning mentioned by #24062
But, the cookie code really doesn't look good to me, so clean up them.
Complete the TODO on `SetCookie`:
> TODO: Copied from gitea.com/macaron/macaron and should be improved
after macaron removed.
In the `for` loop, the value of `membershipsToAdd[org]` and
`membershipsToRemove[org]` is a slice that should be appended instead of
overwritten.
Due to the current overwrite, the LDAP group sync only matches the last
group at the moment.
## Example reproduction
- an LDAP user is both a member of
`cn=admin_staff,ou=people,dc=planetexpress,dc=com` and
`cn=ship_crew,ou=people,dc=planetexpress,dc=com`.
- configuration of `Map LDAP groups to Organization teams ` in
`Authentication Sources`:
```json
{
"cn=admin_staff,ou=people,dc=planetexpress,dc=com":{
"test_organization":[
"admin_staff",
"test_add"
]
},
"cn=ship_crew,ou=people,dc=planetexpress,dc=com":{
"test_organization":[
"ship_crew"
]
}
```
- start `Synchronize external user data` task in the `Dashboard`.
- the user was only added for the team `test_organization.ship_crew`
None of the features of `unrolled/render` package is used.
The Golang builtin "html/template" just works well. Then we can improve
our HTML render to resolve the "$.root.locale.Tr" problem as much as
possible.
Next step: we can have a template render pool (by Clone), then we can
inject global functions with dynamic context to every `Execute` calls.
Then we can use `{{Locale.Tr ....}}` directly in all templates , no need
to pass the `$.root.locale` again and again.
When running listLdapGroupMemberships check if the groupFilter is empty
before using it to list memberships.

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.

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.

There are 2 separate flows of creating a user: authentication and source
sync.
When a group filter is defined, source sync ignores group filter, while
authentication respects it.
With this PR I've fixed this behavior, so both flows now apply this
filter when searching users in LDAP in a unified way.
- Unified LDAP group membership lookup for authentication and source
sync flows
- Replaced custom group membership lookup (used for authentication flow)
with an existing listLdapGroupMemberships method (used for source sync
flow)
- Modified listLdapGroupMemberships and getUserAttributeListedInGroup in
a way group lookup could be called separately
- Added user filtering based on a group membership for a source sync
- Added tests to cover this logic

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.
Fixes #4300
- Move the file `compare.go` and `slice.go` to `slice.go`.
- Fix `ExistsInSlice`, it's buggy
- It uses `sort.Search`, so it assumes that the input slice is sorted.
- It passes `func(i int) bool { return slice[i] == target })` to
`sort.Search`, that's incorrect, check the doc of `sort.Search`.
- Conbine `IsInt64InSlice(int64, []int64)` and `ExistsInSlice(string,
[]string)` to `SliceContains[T]([]T, T)`.
- Conbine `IsSliceInt64Eq([]int64, []int64)` and `IsEqualSlice([]string,
[]string)` to `SliceSortedEqual[T]([]T, T)`.
- Add `SliceEqual[T]([]T, T)` as a distinction from
`SliceSortedEqual[T]([]T, T)`.
- Redesign `RemoveIDFromList([]int64, int64) ([]int64, bool)` to
`SliceRemoveAll[T]([]T, T) []T`.
- Add `SliceContainsFunc[T]([]T, func(T) bool)` and
`SliceRemoveAllFunc[T]([]T, func(T) bool)` for general use.
- Add comments to explain why not `golang.org/x/exp/slices`.
- Add unit tests.
This PR changed the Auth interface signature from
`Verify(http *http.Request, w http.ResponseWriter, store DataStore, sess
SessionStore) *user_model.User`
to
`Verify(http *http.Request, w http.ResponseWriter, store DataStore, sess
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.
This will fix #20563

This is useful in scenarios where the reverse proxy may have knowledge
of user emails, but does not know about usernames set on gitea,
as in the feature request in #19948.
I tested this by setting up a fresh gitea install with one user `mhl`
and email `m.hasnain.lakhani@gmail.com`. I then created a private repo,
and configured gitea to allow reverse proxy authentication.
Via curl I confirmed that these two requests now work and return 200s:
curl http://localhost:3000/mhl/private -I --header "X-Webauth-User: mhl"
curl http://localhost:3000/mhl/private -I --header "X-Webauth-Email: m.hasnain.lakhani@gmail.com"
Before this commit, the second request did not work.
I also verified that if I provide an invalid email or user,
a 404 is correctly returned as before

The recovery, API, Web and package frameworks all create their own HTML
Renderers. This increases the memory requirements of Gitea
unnecessarily with duplicate templates being kept in memory.
Further the reloading framework in dev mode for these involves locking
and recompiling all of the templates on each load. This will potentially
hide concurrency issues and it is inefficient.
This PR stores the templates renderer in the context and stores this
context in the NormalRoutes, it then creates a fsnotify.Watcher
framework to watch files.
The watching framework is then extended to the mailer templates which
were previously not being reloaded in dev.
Then the locales are simplified to a similar structure.
