Improve "gitea doctor" sub-command and fix "help" commands (#26072)
Replace #21790 And close #25965 by the way (it needs a separate fix for 1.20) Major changes: 1. Move "gitea convert" to "gitea doctor conver". The old "gitea doctor" still works as a hidden sub-command (to avoid breaking) 2. Do not write "doctor.log" by default, it's not useful in most cases and causes bugs like 25965 3. Improve documents 4. Fix the "help" commands. Before, the "./gitea doctor" can't show the sub-command help correctly (regression of the last cli/v2 refactoring) After this PR: ``` ./gitea help # show all sub-commands for the app ./gitea doctor # show the sub-commands for the "doctor" ./gitea doctor help # show the sub-commands for the "doctor", as above ```

### doctor check
|
||||
|
||||
Converts an existing MySQL database from utf8 to utf8mb4.
|
||||
Diagnose and potentially fix problems with the current Gitea instance.
|
||||
Several checks are run by default, but additional ones can be run:
|
||||
|
||||
### doctor
|
||||
- `gitea doctor check --list` - will list all the available checks
|
||||
- `gitea doctor check --all` - will run all available checks
|
||||
- `gitea doctor check --default` - will run the default checks
|
||||
- `gitea doctor check --run [check(s),]...` - will run the named checks
|
||||
|
||||
Diagnose the problems of current Gitea instance according the given configuration.
|
||||
Currently there are a check list below:
|
||||
|
||||
- Check if OpenSSH authorized_keys file id correct
|
||||
When your Gitea instance support OpenSSH, your Gitea instance binary path will be written to `authorized_keys`
|
||||
when there is any public key added or changed on your Gitea instance.
|
||||
Sometimes if you moved or renamed your Gitea binary when upgrade and you haven't run `Update the '.ssh/authorized_keys' file with Gitea SSH keys. (Not needed for the built-in SSH server.)` on your Admin Panel. Then all pull/push via SSH will not be work.
|
||||
This check will help you to check if it works well.
|
||||
|
||||
For contributors, if you want to add more checks, you can write a new function like `func(ctx *cli.Context) ([]string, error)` and
|
||||
append it to `doctor.go`.
|
||||
|
||||
```go
|
||||
var checklist = []check{
|
||||
{
|
||||
title: "Check if OpenSSH authorized_keys file id correct",
|
||||
f: runDoctorLocationMoved,
|
||||
},
|
||||
// more checks please append here
|
||||
}
|
||||
```
|
||||
|
||||
This function will receive a command line context and return a list of details about the problems or error.
|
||||
Some problems can be automatically fixed by passing the `--fix` option.
|
||||
Extra logging can be set with `--log-file=...`.

对 Gitea 实例进行诊断，可以修复一些可修复的问题。
|
||||
默认只运行部分检查，额外的检查可以参考：
|
||||
|
||||
### doctor
|
||||
- `gitea doctor check --list` - 列出所有可用的检查
|
||||
- `gitea doctor check --all` - 运行所有可用的检查
|
||||
- `gitea doctor check --default` - 运行默认的检查
|
||||
- `gitea doctor check --run [check(s),]...` - 运行指定的名字的检查
|
||||
|
||||
根据给定的配置诊断当前 Gitea 实例的问题。目前有以下检查清单:
|
||||
|
||||
- 检查 OpenSSH 的 authorized_keys 文件是否正确
|
||||
当您的 Gitea 实例支持 OpenSSH 时，当您的 Gitea 实例添加或更改任何公钥时，Gitea 实例的二进制路径将被写入 `authorized_keys` 文件。
|
||||
有时，如果您在升级时移动或重命名了 Gitea 二进制文件，并且您没有在管理面板上运行“使用 Gitea 的 SSH 密钥更新「.ssh/authorized_keys」文件”操作。那么通过 SSH 的所有拉取/推送操作将无法正常工作。
|
||||
此检查将帮助您检查它是否正常工作。
|
||||
|
||||
对于贡献者，如果您想添加更多的检查项，您可以编写一个新的函数，如 `func(ctx *cli.Context) ([]string, error)`，并将其追加到 `doctor.go` 文件中。
|
||||
|
||||
```go
|
||||
var checklist = []check{
|
||||
{
|
||||
title: "Check if OpenSSH authorized_keys file id correct",
|
||||
f: runDoctorLocationMoved,
|
||||
},
|
||||
// more checks please append here
|
||||
}
|
||||
```
|
||||
|
||||
此函数将接收一个命令行上下文，并返回有关问题或错误的详细信息列表。
|
||||
有些问题可以通过设置 `--fix` 选项进行自动修复。
|
||||
额外的日志可以通过 `--log-file=...` 进行设置。
