Part of #27065
This PR touches functions used in templates. As templates are not static
typed, errors are harder to find, but I hope I catch it all. I think
some tests from other persons do not hurt.
This PR removed `unittest.MainTest` the second parameter
`TestOptions.GiteaRoot`. Now it detects the root directory by current
working directory.

Partially Fix #25041
This PR redefined the meaning of column `is_active` in table
`action_runner_token`.
Before this PR, `is_active` means whether it has been used by any
runner. If it's true, other runner cannot use it to register again.
In this PR, `is_active` means whether it's validated to be used to
register runner. And if it's true, then it can be used to register
runners until it become false. When creating a new `is_active` register
token, any previous tokens will be set `is_active` to false.
This PR adds a new field `RemoteAddress` to both mirror types which
contains the sanitized remote address for easier (database) access to
that information. Will be used in the audit PR if merged.
Part of #27065
This reduces the usage of `db.DefaultContext`. I think I've got enough
files for the first PR. When this is merged, I will continue working on
this.
Considering how many files this PR affect, I hope it won't take to long
to merge, so I don't end up in the merge conflict hell.

Most middleware throw a 404 in case something is not found e.g. a Repo
that is not existing. But most API endpoints don't include the 404
response in their documentation. This PR changes this.
This feature was removed by #22219 to avoid possible CSRF attack.
This PR takes reverseproxy auth for API back but with default disabled.
To prevent possbile CSRF attack, the responsibility will be the
reverseproxy but not Gitea itself.
For those want to enable this `ENABLE_REVERSE_PROXY_AUTHENTICATION_API`,
they should know what they are doing.

Currently, Artifact does not have an expiration and automatic cleanup
mechanism, and this feature needs to be added. It contains the following
key points:
- [x] add global artifact retention days option in config file. Default
value is 90 days.
- [x] add cron task to clean up expired artifacts. It should run once a
day.
- [x] support custom retention period from `retention-days: 5` in
`upload-artifact@v3`.
- [x] artifacts link in actions view should be non-clickable text when
expired.
They currently throw a Internal Server Error when you use them without a
token. Now they correctly return a `token is required` error.
This is no security issue. If you use this endpoints with a token that
don't have the correct permission, you get the correct error. This is
not affected by this PR.

Cargo registry-auth feature requires config.json to have a property
auth-required set to true in order to send token to all registry
requests.
This is ok for git index because you can manually edit the config.json
file to add the auth-required, but when using sparse
(setting index url to
"sparse+https://git.example.com/api/packages/{owner}/cargo/"), the
config.json is dynamically rendered, and does not reflect changes to the
config.json file in the repo.
I see two approaches:
- Serve the real config.json file when fetching the config.json on the
cargo service.
- Automatically detect if the registry requires authorization. (This is
what I implemented in this PR).
What the PR does:
- When a cargo index repository is created, on the config.json, set
auth-required to wether or not the repository is private.
- When the cargo/config.json endpoint is called, set auth-required to
wether or not the request was authorized using an API token.
According to the GitHub API Spec:
https://docs.github.com/en/rest/actions/secrets?apiVersion=2022-11-28#create-or-update-an-organization-secret
Merge the Create and Update secret into a single API.
- Remove the `CreateSecretOption` struct and replace it with
`CreateOrUpdateSecretOption` in `modules/structs/secret.go`
- Update the `CreateOrUpdateOrgSecret` function in
`routers/api/v1/org/action.go` to use `CreateOrUpdateSecretOption`
instead of `UpdateSecretOption`
- Remove the `CreateOrgSecret` function in
`routers/api/v1/org/action.go` and replace it with
`CreateOrUpdateOrgSecret`
- Update the Swagger documentation in
`routers/api/v1/swagger/options.go` and `templates/swagger/v1_json.tmpl`
to reflect the changes in the struct names and function names

Fixes: #26333.
Previously, this endpoint only updates the `StatusCheckContexts` field
when `EnableStatusCheck==true`, which makes it impossible to clear the
array otherwise.
This patch uses slice `nil`-ness to decide whether to update the list of
checks. The field is ignored when either the client explicitly passes in
a null, or just omits the field from the json ([which causes
`json.Unmarshal` to leave the struct field
unchanged](https://go.dev/play/p/Z2XHOILuB1Q)). I think this is a better
measure of intent than whether the `EnableStatusCheck` flag was set,
because it matches the semantics of other field types.
Also adds a test case. I noticed that [`testAPIEditBranchProtection`
only checks the branch
name](c1c83dbaec/tests/integration/api_branch_test.go (L68))
and no other fields, so I added some extra `GET` calls and specific
checks to make sure the fields are changing properly.
I added those checks the existing integration test; is that the right
place for it?

## Archived labels
This adds the structure to allow for archived labels.
Archived labels are, just like closed milestones or projects, a medium to hide information without deleting it.
It is especially useful if there are outdated labels that should no longer be used without deleting the label entirely.
## Changes
1. UI and API have been equipped with the support to mark a label as archived
2. The time when a label has been archived will be stored in the DB
## Outsourced for the future
There's no special handling for archived labels at the moment.
This will be done in the future.

Artifact chunks merging is break on Windows.
```
Gitea Log:
2023/08/03 20:51:15 ...actions/artifacts.go:271:comfirmUploadArtifact() [E] Error merge chunks: parse content range error: input does not match format
```
Artifact uses wrong slash to parse saved chunks path.
Fix #24662.
Replace #24822 and #25708 (although it has been merged)
## Background
In the past, Gitea supported issue searching with a keyword and
conditions in a less efficient way. It worked by searching for issues
with the keyword and obtaining limited IDs (as it is heavy to get all)
on the indexer (bleve/elasticsearch/meilisearch), and then querying with
conditions on the database to find a subset of the found IDs. This is
why the results could be incomplete.
To solve this issue, we need to store all fields that could be used as
conditions in the indexer and support both keyword and additional
conditions when searching with the indexer.
## Major changes
- Redefine `IndexerData` to include all fields that could be used as
filter conditions.
- Refactor `Search(ctx context.Context, kw string, repoIDs []int64,
limit, start int, state string)` to `Search(ctx context.Context, options
*SearchOptions)`, so it supports more conditions now.
- Change the data type stored in `issueIndexerQueue`. Use
`IndexerMetadata` instead of `IndexerData` in case the data has been
updated while it is in the queue. This also reduces the storage size of
the queue.
- Enhance searching with Bleve/Elasticsearch/Meilisearch, make them
fully support `SearchOptions`. Also, update the data versions.
- Keep most logic of database indexer, but remove
`issues.SearchIssueIDsByKeyword` in `models` to avoid confusion where is
the entry point to search issues.
- Start a Meilisearch instance to test it in unit tests.
- Add unit tests with almost full coverage to test
Bleve/Elasticsearch/Meilisearch indexer.

Changes:
- Create `action_tasks_version` table to store the latest version of
each scope (global, org and repo).
- When a job with the status of `waiting` is created, the tasks version
of the scopes it belongs to will increase.
- When the status of a job already in the database is updated to
`waiting`, the tasks version of the scopes it belongs to will increase.
- On Gitea side, in `FeatchTask()`, will try to query the
`action_tasks_version` record of the scope of the runner that call
`FetchTask()`. If the record does not exist, will insert a row. Then,
Gitea will compare the version passed from runner to Gitea with the
version in database, if inconsistent, try pick task. Gitea always
returns the latest version from database to the runner.

To avoid deadlock problem, almost database related functions should be
have ctx as the first parameter.
This PR do a refactor for some of these functions.
current actions artifacts implementation only support single file
artifact. To support multiple files uploading, it needs:
- save each file to each db record with same run-id, same artifact-name
and proper artifact-path
- need change artifact uploading url without artifact-id, multiple files
creates multiple artifact-ids
- support `path` in download-artifact action. artifact should download
to `{path}/{artifact-path}`.
- in repo action view, it provides zip download link in artifacts list
in summary page, no matter this artifact contains single or multiple
files.
Before: the concept "Content string" is used everywhere. It has some
problems:
1. Sometimes it means "base64 encoded content", sometimes it means "raw
binary content"
2. It doesn't work with large files, eg: uploading a 1G LFS file would
make Gitea process OOM
This PR does the refactoring: use "ContentReader" / "ContentBase64"
instead of "Content"
This PR is not breaking because the key in API JSON is still "content":
`` ContentBase64 string `json:"content"` ``

Follow #25229
At present, when the trigger event is `pull_request_target`, the `ref`
and `sha` of `ActionRun` are set according to the base branch of the
pull request. This makes it impossible for us to find the head branch of
the `ActionRun` directly. In this PR, the `ref` and `sha` will always be
set to the head branch and they will be changed to the base branch when
generating the task context.
A couple of notes:
* Future changes should refactor arguments into a struct
* This filtering only is supported by meilisearch right now
* Issue index number is bumped which will cause a re-index
Fixes #24723
Direct serving of content aka HTTP redirect is not mentioned in any of

## ⚠️ BREAKING ⚠️
Before this, `DEFAULT_ACTIONS_URL` cound be set to any custom URLs like
`https://gitea.com` or `http://your-git-server,https://gitea.com`, and
the default value was `https://gitea.com`.
But now, `DEFAULT_ACTIONS_URL` supports only
`github`(`https://github.com`) or `self`(the root url of current Gitea
instance), and the default value is `github`.
If it has configured with a URL, an error log will be displayed and it
will fallback to `github`.
Actually, what we really want to do is always make it
`https://github.com`, however, this may not be acceptable for some
instances of internal use, so there's extra support for `self`, but no
more, even `https://gitea.com`.
Please note that `uses: https://xxx/yyy/zzz` always works and it does
exactly what it is supposed to do.
Although it's breaking, I belive it should be backported to `v1.20` due
to some security issues.
Follow-up on the runner side:

In the process of doing a bit of automation via the API, we've
discovered a _small_ issue in the Swagger definition. We tried to create
a push mirror for a repository, but our generated client raised an
exception due to an unexpected status code.
When looking at this function:
3c7f5ed7b5/routers/api/v1/repo/mirror.go (L236-L240)
We see it defines `201 - Created` as response:
3c7f5ed7b5/routers/api/v1/repo/mirror.go (L260-L262)
But it actually returns `200 - OK`:
3c7f5ed7b5/routers/api/v1/repo/mirror.go (L373)
So I've just updated the Swagger definitions to match the code😀

This PR adds the support for
[`pull_request_target`](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request_target)
workflow trigger. `pull_request_target` is similar to `pull_request`,
but the workflow triggered by the `pull_request_target` event runs in
the context of the base branch of the pull request rather than the head
branch. Since the workflow from the base is considered trusted, it can
access the secrets and doesn't need approvals to run.
1. The "web" package shouldn't depends on "modules/context" package,
instead, let each "web context" register themselves to the "web"
package.
2. The old Init/Free doesn't make sense, so simplify it
* The ctx in "Init(ctx)" is never used, and shouldn't be used that way
* The "Free" is never called and shouldn't be called because the SSPI
instance is shared

This PR rewrites storage configuration read sequences with some breaks
and tests. It becomes more strict than before and also fixed some
inherit problems.
- Move storage's MinioConfig struct into setting, so after the
configuration loading, the values will be stored into the struct but not
still on some section.
- All storages configurations should be stored on one section,
configuration items cannot be overrided by multiple sections. The
prioioty of configuration is `[attachment]` > `[storage.attachments]` |
`[storage.customized]` > `[storage]` > `default`
- For extra override configuration items, currently are `SERVE_DIRECT`,
`MINIO_BASE_PATH`, `MINIO_BUCKET`, which could be configured in another
section. The prioioty of the override configuration is `[attachment]` >
`[storage.attachments]` > `default`.
- Add more tests for storages configurations.
- Update the storage documentations.

original PR:
1. add some missing parameter descriptions
2. set correct `required` option for required parameters
3. change endpoint description to match it full functionality (every
kind of file modification is supported, not just creating and updating)
## Changes
- Adds the following high level access scopes, each with `read` and
`write` levels:
- `activitypub`
- `admin` (hidden if user is not a site admin)
- `misc`
- `notification`
- `organization`
- `package`
- `issue`
- `repository`
- `user`
- Adds new middleware function `tokenRequiresScopes()` in addition to
`reqToken()`
- `tokenRequiresScopes()` is used for each high-level api section
- _if_ a scoped token is present, checks that the required scope is
included based on the section and HTTP method
- `reqToken()` is used for individual routes
- checks that required authentication is present (but does not check
scope levels as this will already have been handled by
`tokenRequiresScopes()`
- Adds migration to convert old scoped access tokens to the new set of
scopes
- Updates the user interface for scope selection

## tokenRequiresScopes Design Decision
- `tokenRequiresScopes()` was added to more reliably cover api routes.
For an incoming request, this function uses the given scope category
(say `AccessTokenScopeCategoryOrganization`) and the HTTP method (say
`DELETE`) and verifies that any scoped tokens in use include
`delete:organization`.
- `reqToken()` is used to enforce auth for individual routes that
require it. If a scoped token is not present for a request,
`tokenRequiresScopes()` will not return an error
## TODO
- [x] Alphabetize scope categories
- [x] Change 'public repos only' to a radio button (private vs public).
Also expand this to organizations
- [X] Disable token creation if no scopes selected. Alternatively, show
warning
- [x] `reqToken()` is missing from many `POST/DELETE` routes in the api.
`tokenRequiresScopes()` only checks that a given token has the correct
scope, `reqToken()` must be used to check that a token (or some other
auth) is present.
- _This should be addressed in this PR_
- [x] The migration should be reviewed very carefully in order to
minimize access changes to existing user tokens.
- _This should be addressed in this PR_
- [x] Link to api to swagger documentation, clarify what
read/write/delete levels correspond to
- [x] Review cases where more than one scope is needed as this directly
deviates from the api definition.
- _This should be addressed in this PR_
- For example:
```go
m.Group("/users/{username}/orgs", func() {
m.Get("", reqToken(), org.ListUserOrgs)
m.Get("/{org}/permissions", reqToken(), org.GetUserOrgsPermissions)
}, tokenRequiresScopes(auth_model.AccessTokenScopeCategoryUser,
auth_model.AccessTokenScopeCategoryOrganization),
context_service.UserAssignmentAPI())
```
## Future improvements
- [ ] Add required scopes to swagger documentation
- [ ] Redesign `reqToken()` to be opt-out rather than opt-in
- [ ] Subdivide scopes like `repository`
- [ ] Once a token is created, if it has no scopes, we should display
text instead of an empty bullet point
- [ ] If the 'public repos only' option is selected, should read
categories be selected by default

[GitLab](https://docs.gitlab.com/ee/api/commits.html#create-a-commit-with-multiple-files-and-actions).

It also fixed a bug that tags are not sync because `git remote --prune
origin` will not remove local tags if remote removed.
We in fact should use `git fetch --prune --tags origin` but not `git
remote update origin` to do the sync.
Some answer from ChatGPT as ref.
> If the git fetch --prune --tags command is not working as expected,
there could be a few reasons why. Here are a few things to check:
>
>Make sure that you have the latest version of Git installed on your
system. You can check the version by running git --version in your
terminal. If you have an outdated version, try updating Git and see if
that resolves the issue.
>
>Check that your Git repository is properly configured to track the
remote repository's tags. You can check this by running git config
--get-all remote.origin.fetch and verifying that it includes
+refs/tags/*:refs/tags/*. If it does not, you can add it by running git
config --add remote.origin.fetch "+refs/tags/*:refs/tags/*".
>
>Verify that the tags you are trying to prune actually exist on the
remote repository. You can do this by running git ls-remote --tags
origin to list all the tags on the remote repository.
>
>Check if any local tags have been created that match the names of tags
on the remote repository. If so, these local tags may be preventing the
git fetch --prune --tags command from working properly. You can delete
local tags using the git tag -d command.

This adds the ability to pin important Issues and Pull Requests. You can
also move pinned Issues around to change their Position. Resolves #2175.
## Screenshots
The Design was mostly copied from the Projects Board.
## Implementation
This uses a new `pin_order` Column in the `issue` table. If the value is
set to 0, the Issue is not pinned. If it's set to a bigger value, the
value is the Position. 1 means it's the first pinned Issue, 2 means it's
the second one etc. This is dived into Issues and Pull requests for each
Repo.
## TODO
- [x] You can currently pin as many Issues as you want. Maybe we should
add a Limit, which is configurable. GitHub uses 3, but I prefer 6, as
this is better for bigger Projects, but I'm open for suggestions.
- [x] Pin and Unpin events need to be added to the Issue history.
- [x] Tests
- [x] Migration
**The feature itself is currently fully working, so tester who may find
weird edge cases are very welcome!**

`RequestedReviewer` .
- setting the action to either **review_requested** or
**review_request_removed** based on the operation.
- adding the `RequestedReviewers` field to the issues_model.PullRequest.
This field will be loaded into the PullRequest through
`LoadRequestedReviewers()` when `ToAPIPullRequest` is called.
After the Pull Request is merged, I will supplement the relevant
documentation.
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`
