Refactor internal API for git commands, use meaningful messages instead of "Internal Server Error" (#23687) # Why this PR comes At first, I'd like to help users like #23636 (there are a lot) The unclear "Internal Server Error" is quite anonying, scare users, frustrate contributors, nobody knows what happens. So, it's always good to provide meaningful messages to end users (of course, do not leak sensitive information). When I started working on the "response message to end users", I found that the related code has a lot of technical debt. A lot of copy&paste code, unclear fields and usages. So I think it's good to make everything clear. # Tech Backgrounds Gitea has many sub-commands, some are used by admins, some are used by SSH servers or Git Hooks. Many sub-commands use "internal API" to communicate with Gitea web server. Before, Gitea server always use `StatusCode + Json "err" field` to return messages. * The CLI sub-commands: they expect to show all error related messages to site admin * The Serv/Hook sub-commands (for git clients): they could only show safe messages to end users, the error log could only be recorded by "SSHLog" to Gitea web server. In the old design, it assumes that: * If the StatusCode is 500 (in some functions), then the "err" field is error log, shouldn't be exposed to git client. * If the StatusCode is 40x, then the "err" field could be exposed. And some functions always read the "err" no matter what the StatusCode is. The old code is not strict, and it's difficult to distinguish the messages clearly and then output them correctly. # This PR To help to remove duplicate code and make everything clear, this PR introduces `ResponseExtra` and `requestJSONResp`. * `ResponseExtra` is a struct which contains "extra" information of a internal API response, including StatusCode, UserMsg, Error * `requestJSONResp` is a generic function which can be used for all cases to help to simplify the calls. * Remove all `map["err"]`, always use `private.Response{Err}` to construct error messages. * User messages and error messages are separated clearly, the `fail` and `handleCliResponseExtra` will output correct messages. * Replace all `Internal Server Error` messages with meaningful (still safe) messages. This PR saves more than 300 lines, while makes the git client messages more clear.

Refactor internal API for git commands, use meaningful messages instead of "Internal Server Error" (#23687) # Why this PR comes At first, I'd like to help users like #23636 (there are a lot) The unclear "Internal Server Error" is quite anonying, scare users, frustrate contributors, nobody knows what happens. So, it's always good to provide meaningful messages to end users (of course, do not leak sensitive information). When I started working on the "response message to end users", I found that the related code has a lot of technical debt. A lot of copy&paste code, unclear fields and usages.

Use the type RefName for all the needed places and fix pull mirror sync bugs (#24634) This PR replaces all string refName as a type `git.RefName` to make the code more maintainable. Fix #15367 Replaces #23070 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. --------- Co-authored-by: delvh <dev.lh@web.de>

Implement actions (#21937) Close #13539. Co-authored by: @lunny @appleboy @fuxiaohei and others. Related projects: - https://gitea.com/gitea/actions-proto-def - https://gitea.com/gitea/actions-proto-go - https://gitea.com/gitea/act - https://gitea.com/gitea/act_runner ### Summary The target of this PR is to bring a basic implementation of "Actions", an internal CI/CD system of Gitea. That means even though it has been merged, the state of the feature is **EXPERIMENTAL**, and please note that: - It is disabled by default; - It shouldn't be used in a production environment currently; - It shouldn't be used in a public Gitea instance currently; - Breaking changes may be made before it's stable. **Please comment on #13539 if you have any different product design ideas**, all decisions reached there will be adopted here. But in this PR, we don't talk about **naming, feature-creep or alternatives**. ### ⚠️ Breaking `gitea-actions` will become a reserved user name. If a user with the name already exists in the database, it is recommended to rename it. ### Some important reviews - What is `DEFAULT_ACTIONS_URL` in `app.ini` for? - https://github.com/go-gitea/gitea/pull/21937#discussion_r1055954954 - Why the api for runners is not under the normal `/api/v1` prefix? - https://github.com/go-gitea/gitea/pull/21937#discussion_r1061173592 - Why DBFS? - https://github.com/go-gitea/gitea/pull/21937#discussion_r1061301178 - Why ignore events triggered by `gitea-actions` bot? - https://github.com/go-gitea/gitea/pull/21937#discussion_r1063254103 - Why there's no permission control for actions? - https://github.com/go-gitea/gitea/pull/21937#discussion_r1090229868 ### What it looks like <details> #### Manage runners <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205870657-c72f590e-2e08-4cd4-be7f-2e0abb299bbf.png"> #### List runs <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205872794-50fde990-2b45-48c1-a178-908e4ec5b627.png"> #### View logs <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205872501-9b7b9000-9542-4991-8f55-18ccdada77c3.png"> </details> ### How to try it <details> #### 1. Start Gitea Clone this branch and [install from source](https://docs.gitea.io/en-us/install-from-source). Add additional configurations in `app.ini` to enable Actions: ```ini [actions] ENABLED = true ``` Start it. If all is well, you'll see the management page of runners: <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205877365-8e30a780-9b10-4154-b3e8-ee6c3cb35a59.png"> #### 2. Start runner Clone the [act_runner](https://gitea.com/gitea/act_runner), and follow the [README](https://gitea.com/gitea/act_runner/src/branch/main/README.md) to start it. If all is well, you'll see a new runner has been added: <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205878000-216f5937-e696-470d-b66c-8473987d91c3.png"> #### 3. Enable actions for a repo Create a new repo or open an existing one, check the `Actions` checkbox in settings and submit. <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205879705-53e09208-73c0-4b3e-a123-2dcf9aba4b9c.png"> <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205879383-23f3d08f-1a85-41dd-a8b3-54e2ee6453e8.png"> If all is well, you'll see a new tab "Actions": <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205881648-a8072d8c-5803-4d76-b8a8-9b2fb49516c1.png"> #### 4. Upload workflow files Upload some workflow files to `.gitea/workflows/xxx.yaml`, you can follow the [quickstart](https://docs.github.com/en/actions/quickstart) of GitHub Actions. Yes, Gitea Actions is compatible with GitHub Actions in most cases, you can use the same demo: ```yaml name: GitHub Actions Demo run-name: ${{ github.actor }} is testing out GitHub Actions 🚀 on: [push] jobs: Explore-GitHub-Actions: runs-on: ubuntu-latest steps: - run: echo "🎉 The job was automatically triggered by a ${{ github.event_name }} event." - run: echo "🐧 This job is now running on a ${{ runner.os }} server hosted by GitHub!" - run: echo "🔎 The name of your branch is ${{ github.ref }} and your repository is ${{ github.repository }}." - name: Check out repository code uses: actions/checkout@v3 - run: echo "💡 The ${{ github.repository }} repository has been cloned to the runner." - run: echo "🖥️ The workflow is now ready to test your code on the runner." - name: List files in the repository run: | ls ${{ github.workspace }} - run: echo "🍏 This job's status is ${{ job.status }}." ``` If all is well, you'll see a new run in `Actions` tab: <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205884473-79a874bc-171b-4aaf-acd5-0241a45c3b53.png"> #### 5. Check the logs of jobs Click a run and you'll see the logs: <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/205884800-994b0374-67f7-48ff-be9a-4c53f3141547.png"> #### 6. Go on You can try more examples in [the documents](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions) of GitHub Actions, then you might find a lot of bugs. Come on, PRs are welcome. </details> See also: [Feature Preview: Gitea Actions](https://blog.gitea.io/2022/12/feature-preview-gitea-actions/) --------- Co-authored-by: a1012112796 <1012112796@qq.com> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com> Co-authored-by: delvh <dev.lh@web.de> Co-authored-by: ChristopherHX <christopher.homberger@web.de> Co-authored-by: John Olheiser <john.olheiser@gmail.com>
