# Migration Features
|
|
|
|
|
|
|
|
|
|
The new migration features were introduced in Gitea 1.9.0. It defines two interfaces to support migrating
|
|
|
|
|
repositories data from other git host platforms to gitea or, in the future migrating gitea data to other
|
|
|
|
|
git host platforms. Currently, only the migrations from github via APIv3 to Gitea is implemented.
|
|
|
|
|
|
|
|
|
|
First of all, Gitea defines some standard objects in packages `modules/migrations/base`. They are
|
|
|
|
|
`Repository`, `Milestone`, `Release`, `Label`, `Issue`, `Comment`, `PullRequest`.
|
|
|
|
|
|
|
|
|
|
## Downloader Interfaces
|
|
|
|
|
|
|
|
|
|
To migrate from a new git host platform, there are two steps to be updated.
|
|
|
|
|
|
|
|
|
|
- You should implement a `Downloader` which will get all kinds of repository informations.
|
|
|
|
|
- You should implement a `DownloaderFactory` which is used to detect if the URL matches and
|
|
|
|
|
create a Downloader.
|
|
|
|
|
- You'll need to register the `DownloaderFactory` via `RegisterDownloaderFactory` on init.
|
|
|
|
|
|
|
|
|
|
```Go
|
|
|
|
|
type Downloader interface {
|
|
|
|
|
GetRepoInfo() (*Repository, error)
|
|
|
|
|
GetTopics() ([]string, error)
|
|
|
|
|
GetMilestones() ([]*Milestone, error)
|
|
|
|
|
GetReleases() ([]*Release, error)
|
|
|
|
|
GetLabels() ([]*Label, error)
|
|
|
|
|
GetIssues(start, limit int) ([]*Issue, error)
|
|
|
|
|
GetComments(issueNumber int64) ([]*Comment, error)
|
|
|
|
|
GetPullRequests(start, limit int) ([]*PullRequest, error)
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
```Go
|
|
|
|
|
type DownloaderFactory interface {
|
|
|
|
|
Match(opts MigrateOptions) (bool, error)
|
|
|
|
|
New(opts MigrateOptions) (Downloader, error)
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## Uploader Interface
|
|
|
|
|
|
|
|
|
|
Currently, only a `GiteaLocalUploader` is implemented, so we only save downloaded
|
|
|
|
|
data via this `Uploader` on the local Gitea instance. Other uploaders are not supported
|
|
|
|
|
and will be implemented in future.
|
|
|
|
|
|
|
|
|
|
```Go
|
|
|
|
|
// Uploader uploads all the informations
|
|
|
|
|
type Uploader interface {
|
|
|
|
|
CreateRepo(repo *Repository, includeWiki bool) error
|
|
|
|
|
CreateMilestone(milestone *Milestone) error
|
|
|
|
|
CreateRelease(release *Release) error
|
|
|
|
|
CreateLabel(label *Label) error
|
|
|
|
|
CreateIssue(issue *Issue) error
|
|
|
|
|
CreateComment(issueNumber int64, comment *Comment) error
|
|
|
|
|
CreatePullRequest(pr *PullRequest) error
|
|
|
|
|
Rollback() error
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
```
|
