- Add a `purpose` column, this allows the `forgejo_auth_token` table to
be used by other parts of Forgejo, while still enjoying the
no-compromise architecture.
- Remove the 'roll your own crypto' time limited code functions and
migrate them to the `forgejo_auth_token` table. This migration ensures
generated codes can only be used for their purpose and ensure they are
invalidated after their usage by deleting it from the database, this
also should help making auditing of the security code easier, as we're
no longer trying to stuff a lot of data into a HMAC construction.
-Helper functions are rewritten to ensure a safe-by-design approach to
these tokens.
- Add the `forgejo_auth_token` to dbconsistency doctor and add it to the
`deleteUser` function.
- TODO: Add cron job to delete expired authorization tokens.
- Unit and integration tests added.

- Currently if the password, primary mail, TOTP or security keys are
changed, no notification is made of that and makes compromising an
account a bit easier as it's essentially undetectable until the original
person tries to log in. Although other changes should be made as
well (re-authing before allowing a password change), this should go a
long way of improving the account security in Forgejo.
- Adds a mail notification for password and primary mail changes. For
the primary mail change, a mail notification is sent to the old primary
mail.
- Add a mail notification when TOTP or a security keys is removed, if no
other 2FA method is configured the mail will also contain that 2FA is
no longer needed to log into their account.
- `MakeEmailAddressPrimary` is refactored to the user service package,
as it now involves calling the mailer service.
- Unit tests added.
- Integration tests added.
The avatar must not be unset in the database if there is a failure to
remove the avatar file from storage (file or S3). The two operations
are wrapped in a transaction for that purpose and this test verifies
it is effective.

Fix#30378
(cherry picked from commit 0fe9f93eb4c94d55e43b18b9c3cc6d513a34c0b5)
Conflicts:
- models/organization/org.go
- services/repository/delete.go
- services/user/delete.go
In all three cases, conflicts were resolved by manually adding
the lines added by the Gitea patch, keeping the Forgejo code
surrounding them.
- `user_model.DeleteInactiveEmailAddresses` related code was added in
Gogs as part to delete inactive users, however since then the related
code to delete users has changed and this code now already delete email
addresses of the user, it's therefore not needed anymore to
`DeleteInactiveEmailAddresses`.
- The call to `DeleteInactiveEmailAddresses` can actually cause issues.
As the associated user might not have been deleted, because it
was not older than the specified `olderThan` argument. Therefore causing
a database inconsistency and lead to internal server errors if the user
tries to activate their account.
- Adds unit test to verify correct behavior (fails without this patch).
Repositories displaying an "Add more..." tab on the header is a neat way
to let people discover they can enable more units. However, displaying
it all the time for repository owners, even when they deliberately do
not want to enable more units gets noisy very fast.
As such, this patch introduces a new setting which lets people disable
this hint under the appearance settings.
Fixes#2378.

[MODERATION] Refactor integration testing (squash)
- Motivation for this PR is that I'd noticed that a lot of repeated
calls are happening between the test functions and that certain tests
weren't using helper functions like `GetCSRF`, therefor this refactor of
the integration tests to keep it: clean, small and hopefully more
maintainable and understandable.
- There are now three integration tests: `TestBlockUser`,
`TestBlockUserFromOrganization` and `TestBlockActions` (and has been
moved in that order in the source code).
- `TestBlockUser` is for doing blocking related actions as an user and
`TestBlockUserFromOrganization` as an organisation, even though they
execute the same kind of tests they do not share any database calls or
logic and therefor it currently doesn't make sense to merge them
together (hopefully such oppurtinutiy might be presented in the future).
- `TestBlockActions` now contain all tests for actions that should be
blocked after blocking has happened, most tests now share the same doer
and blocked users and a extra fixture has been added to make this
possible for the comment test.
- Less code, more comments and more re-use between tests.

Fixes#28660
Fixes an admin api bug related to `user.LoginSource`
Fixed `/user/emails` response not identical to GitHub api
This PR unifies the user update methods. The goal is to keep the logic
only at one place (having audit logs in mind). For example, do the
password checks only in one method not everywhere a password is updated.
After that PR is merged, the user creation should be next.
Introduce the new generic deletion methods
- `func DeleteByID[T any](ctx context.Context, id int64) (int64, error)`
- `func DeleteByIDs[T any](ctx context.Context, ids ...int64) error`
- `func Delete[T any](ctx context.Context, opts FindOptions) (int64,
error)`
So, we no longer need any specific deletion method and can just use
the generic ones instead.

This PR is a refactor at the beginning. And now it did 4 things.
- [x] Move renaming organizaiton and user logics into services layer and
merged as one function
- [x] Support rename a user capitalization only. For example, rename the
user from `Lunny` to `lunny`. We just need to change one table `user`
and others should not be touched.
- [x] Before this PR, some renaming were missed like `agit`
- [x] Fix bug the API reutrned from `http.StatusNoContent` to `http.StatusOK`
this is a simple endpoint that adds the ability to rename users to the
admin API.
Note: this is not in a mergeable state. It would be better if this was
handled by a PATCH/POST to the /api/v1/admin/users/{username} endpoint
and the username is modified.

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.
- Unify the hashing code for repository and user avatars into a
function.
- Use a sane hash function instead of MD5.
- Only require hashing once instead of twice(w.r.t. hashing for user
avatar).
- Improve the comment for the hashing code of why it works.
