源导入

关于源导入 API

源导入 API 可让您从 Git、Subversion、Mercurial 或 Team Foundation Version Control 源仓库开始导入。这是与 GitHub Importer 相同的功能。更多信息请参阅“使用 GitHub Importer 导入仓库”。如果导入中存在大型文件,则典型的源导入将开始导入,然后(可选)更新作者和/或更新使用 Git LFS 的首选项。 您也可以创建侦听 RepositoryImportEvent 的 web 挂钩来了解导入的状态。

在此图中可以看到更详细的示例:

Get an import status

View the progress of an import.

Import status

This section includes details about the possible values of the status field of the Import Progress response.

An import that does not have errors will progress through these steps:

  • detecting - the "detection" step of the import is in progress because the request did not include a vcs parameter. The import is identifying the type of source control present at the URL.
  • importing - the "raw" step of the import is in progress. This is where commit data is fetched from the original repository. The import progress response will include commit_count (the total number of raw commits that will be imported) and percent (0 - 100, the current progress through the import).
  • mapping - the "rewrite" step of the import is in progress. This is where SVN branches are converted to Git branches, and where author updates are applied. The import progress response does not include progress information.
  • pushing - the "push" step of the import is in progress. This is where the importer updates the repository on GitHub. The import progress response will include push_percent, which is the percent value reported by git push when it is "Writing objects".
  • complete - the import is complete, and the repository is ready on GitHub.

If there are problems, you will see one of these in the status field:

  • auth_failed - the import requires authentication in order to connect to the original repository. To update authentication for the import, please see the Update an import section.
  • error - the import encountered an error. The import progress response will include the failed_step and an error message. Contact GitHub Support for more information.
  • detection_needs_auth - the importer requires authentication for the originating repository to continue detection. To update authentication for the import, please see the Update an import section.
  • detection_found_nothing - the importer didn't recognize any source control at the URL. To resolve, Cancel the import and retry with the correct URL.
  • detection_found_multiple - the importer found several projects or repositories at the provided URL. When this is the case, the Import Progress response will also include a project_choices field with the possible project choices as values. To update project choice, please see the Update an import section.

The project_choices field

When multiple projects are found at the provided URL, the response hash will include a project_choices field, the value of which is an array of hashes each representing a project choice. The exact key/value pairs of the project hashes will differ depending on the version control type.

Git LFS related fields

This section includes details about Git LFS related fields that may be present in the Import Progress response.

  • use_lfs - describes whether the import has been opted in or out of using Git LFS. The value can be opt_in, opt_out, or undecided if no action has been taken.
  • has_large_files - the boolean value describing whether files larger than 100MB were found during the importing step.
  • large_files_size - the total size in gigabytes of files larger than 100MB found in the originating repository.
  • large_files_count - the total number of files larger than 100MB found in the originating repository. To see a list of these files, make a "Get Large Files" request.

Update an import

An import can be updated with credentials or a project choice by passing in the appropriate parameters in this API request. If no parameters are provided, the import will be restarted.

Some servers (e.g. TFS servers) can have several projects at a single URL. In those cases the import progress will have the status detection_found_multiple and the Import Progress response will include a project_choices array. You can select the project to import by providing one of the objects in the project_choices array in the update request.

Get commit authors

Each type of source control system represents authors in a different way. For example, a Git commit author has a display name and an email address, but a Subversion commit author just has a username. The GitHub Importer will make the author information valid, but the author might not be correct. For example, it will change the bare Subversion username hubot into something like hubot <hubot@12341234-abab-fefe-8787-fedcba987654>.

This endpoint and the Map a commit author endpoint allow you to provide correct Git author information.
