REST API

This page describes the code owners REST endpoints that are added by the @PLUGIN@ plugin.

Please also take note of the general information on the REST API.

Project Endpoints

Get Code Owner Project Config

‘GET /projects/{project-name}/code_owners.project_config’

Gets the code owner project configuration.

As a response a CodeOwnerProjectConfigInfo entity is returned that describes the code owner project configuration.

The response includes the configuration of all branches. If a caller is interested in a particular branch only, the Get Code Owner Branch Config REST endpoint should be used instead, as that REST endpoint is much faster if the project contains many branches.

Request

  GET /projects/foo%2Fbar/code_owners.project_config HTTP/1.0

Response

  HTTP/1.1 200 OK
  Content-Disposition: attachment
  Content-Type: application/json; charset=UTF-8

      }
    ]
  }

Check Code Owner Config Files

‘POST /projects/{project-name}/code_owners.check_config’

Checks/validates the code owner config files in a project.

Requires that the caller is an owner of the project.

Input options can be set in the request body as a CheckCodeOwnerConfigFilesInput entity.

No validation is done for branches for which the code owner functionality is disabled, unless validate_disabled_branches is set to true in the input.

As a response a map is returned that maps a branch name to a map that maps an owner configuration file path to a list of ConsistencyProblemInfo entities.

Code owner config files that have no issues are omitted from the response.

Branch Endpoints

Get Code Owner Branch Config

‘GET /projects/{project-name}/branches/{branch-id}/code_owners.branch_config’

Gets the code owner branch configuration.

As a response a CodeOwnerBranchConfigInfo entity is returned that describes the code owner branch configuration.

Request

  GET /projects/foo%2Fbar/branches/master/code_owners.branch_config HTTP/1.0

List Code Owner Config Files

‘GET /projects/{project-name}/branches/{branch-id}/code_owners.config_files/’

Lists the code owner config files in a branch.

This REST endpoint scans all code owner config files in the branch and it is expected that it can take a long time if the branch contains many files. This is why this REST endpoint must not be used in any critical paths where performance matters.

The following request parameters can be specified:

Field Name		Description
`include-non-parsable-files`	optional	Includes non-parseable code owner config files in the response. By default `false`. Cannot be used in combination with the `email` option.
`email`	optional	Code owner email that must appear in the returned code owner config files.

Request

  GET /projects/foo%2Fbar/branches/master/code_owners.config_files HTTP/1.0

As response the paths of the code owner config files are returned as a list. The result also includes code owner config that use name prefixes (‘<prefix>_OWNERS’) or name extensions (‘OWNERS_<extension>’).

Non-parseable code owner config files are omitted from the response, unless the include-non-parsable-files option was set.

Response

  HTTP/1.1 200 OK
  Content-Disposition: attachment
  Content-Type: application/json; charset=UTF-8

  )]}'

  ]

Rename Email In Code Owner Config Files

‘POST /projects/{project-name}/branches/{branch-id}/code_owners.rename/’

Renames an email in all code owner config files in the branch.

The old and new email must be specified in the request body as RenameEmailInput.

The old and new email must both belong to the same Gerrit account.

All updates are done atomically within one commit. The calling user will be the author of this commit.

Requires that the calling user is a project owner (Owner permission on ‘refs/*’) or has direct push permissions for the branch.

Request

  POST /projects/foo%2Fbar/branches/master/code_owners.rename HTTP/1.0

Response

As response a RenameEmailResultInfo entity is returned.

[EXPERIMENTAL] Get Code Owner Config

‘GET /projects/{project-name}/branches/{branch-id}/code_owners.config/{path}’

Gets a code owner config for a path in a branch.

The code owner config is returned as CodeOwnerConfigInfo entity

This REST endpoint is experimental which means that the response format is likely still going to be changed. It is only available if experimental REST endpoints are enabled in gerrit.config.

Request

  GET /projects/foo%2Fbar/branches/master/code_owners.config/%2Fdocs%2Fconfig HTTP/1.0

Response

  HTTP/1.1 200 OK
  Content-Disposition: attachment
  Content-Type: application/json; charset=UTF-8

        {
          "email": "john.doe@example.com"
        }
      ]
    ]
  }

If the path does not exist or if no code owner config exists for the path ‘204 No Content’ is returned.

List Code Owners for path in branch

‘GET /projects/{project-name}/branches/{branch-id}/code_owners/{path}’

Lists the accounts that are code owners of a file or folder in a branch.

The code owners are computed from the owner configuration at the tip of the specified branch.

Code owners that

are inactive
are not visible to the calling user (according to accounts.visibility setting)
are referenced by non-visible secondary emails
are not resolvable (emails for which no Gerrit account exists)
are ambiguous (the same email is assigned to multiple accounts)
are referenced by an email with a disallowed domain (see allowedEmailDomain configuration)
do not have read access to the branch

are omitted from the result.

The following request parameters can be specified:

Field Name		Description
`o`	optional	Account option that controls which fields in the returned accounts should be populated. Can be specified multiple times. If not given, only the `_account_id` field for the account ID is populated.
`O`	optional	Account option in hex. For the explanation see `o` parameter.
`limit`\|`n`	optional	Limit defining how many code owners should be returned at most. By default 10.
`revision`	optional	Revision from which the code owner configs should be read as commit SHA1. Can be used to read historic code owners from this branch, but imports from other branches or repositories as well as default and global code owners from `refs/meta/config` are still read from the current revisions. If not specified the code owner configs are read from the HEAD revision of the branch. Not supported for getting code owners for a path in a change.

As a response a list of CodeOwnerInfo entities is returned. The returned code owners are sorted by an internal score that expresses how good the code owners are considered as reviewers/approvers for the path. Code owners with higher scores are returned first. If code owners have the same score the order is random.

Request

  GET /projects/foo%2Fbar/branches/master/code_owners/docs%2Findex.md HTTP/1.0

Response

  HTTP/1.1 200 OK

Change Endpoints

Get Code Owner Status

‘GET /changes/{change-id}/code_owners.status’

Gets the code owner statuses for the files in a change.

The code owner statuses are always listed for the files in the current revision of the change (latest patch set).

The code owner statuses are returned as a CodeOwnerStatusInfo entity.

Request

  GET /changes/275378/code_owners.status HTTP/1.0

  HTTP/1.1 200 OK
  Content-Disposition: attachment
  Content-Type: application/json; charset=UTF-8

          "path": "docs/readme.md",
          "status": "APPROVED"
        }
      },
      {
        "change_type": "DELETED",
        "old_path_status" {
          "path": "docs/todo.txt",

          "status": "APPROVED"
        }
      }
    ]
  }

If the destination branch of a change no longer exists (e.g. because it was deleted), 409 Conflict is returned. Since the code owners are retrieved from the destination branch, computing the code owner status is not possible, if the destination branch is missing.

Revision Endpoints

Suggest Code Owners for path in change

‘GET /changes/{change-id}/revisions/{revison-id}/code_owners/{path}’

Suggests accounts that are code owners of a file in a change revision.

The code owners are computed from the owner configuration at the tip of the change's destination branch.

This REST endpoint has the exact same request and response format as the REST endpoint to list code owners for a path in a branch, but filters out code owners that which should be omitted from the code owner suggestion.

The following code owners are filtered out additionally:

service users (members of the Service Users group)
the change owner (since the change owner cannot be added as reviewer)

Check Code Owner Config Files In Revision

‘POST /changes/{change-id}/revisions/{revison-id}/code_owners.check_config’

Checks/validates the code owner config files in a revision that have been modified.

The validation is performed from the perspective of the uploader, so that the validation is exactly the same as the validation that will be done on submit.

Input options can be set in the request body as a CheckCodeOwnerConfigFilesInRevisionInput entity.

As a response a map is returned that that maps an owner configuration file path to a list of ConsistencyProblemInfo entities.

Code owner config files that were not modified in the revision are omitted from the response.

Request

  POST /changes/20187/revisions/current/code_owners.check_config HTTP/1.0

Response

  HTTP/1.1 200 OK
  Content-Disposition: attachment
  Content-Type: application/json; charset=UTF-8

General Responses

All REST endpoints may return the following responses:

409 Conflict is returned if a request cannot be executed due to:
- an non-parseable code owner config file (in this case the project owners need to fix the code owner config file)
- an invalid plugin configuration (in this case the project owners need to fix the code-owners plugin configuration)

IDs

{path}

An arbitrary absolute path.

The leading ‘/’ can be omitted.

The path may or may not exist in the branch.

JSON Entities

BackendInfo

The BackendInfo entity describes the code owner backend configuration.

Field Name		Description
`id`		ID of the code owner backend that is configured for the project.
`ids_by_branch`	optional	IDs of the code owner backends that are configured for individual branches as map of full branch names to code owner backend IDs. Only contains entries for branches for which a code owner backend is configured that differs from the backend that is configured for the project (see `id` field). Configurations for non-existing and non-visible branches are omitted. Not set if no branch specific backend configuration is returned.

CheckCodeOwnerConfigFilesInput

The CheckCodeOwnerConfigFilesInput allows to set options for the Check Code Owner Config Files REST endpoint.

Field Name		Description
`validate_disabled_branches`	optional	Whether code owner config files in branches for which the code owners functionality is disabled should be validated too. By default unset, `false`.
`branches`	optional	List of branches for which code owner config files should be validated. The `refs/heads/` prefix may be omitted. By default unset, which means that code owner config files in all branches should be validated.
`path`	optional	Glob that limits the validation to code owner config files that have a path that matches this glob. By default unset, which means that all code owner config files should be validated.

CheckCodeOwnerConfigFilesInRevisionInput

The CheckCodeOwnerConfigFilesInRevisionInput allows to set options for the Check Code Owner Config Files In Revision REST endpoint.
