This implementation includes abstractions for performing HTTP operations, and wrappers for those to interpret responses as JSON data.

HostingService subclasses can also include an override of this class to add additional checking (such as GitHub’s checking of rate limit headers), or add higher-level API functionality.

class HostingService(account)[source]¶

Bases: object

An interface to a hosting service for repositories and bug trackers.

HostingService subclasses are used to more easily configure repositories and to make use of third party APIs to perform special operations not otherwise usable by generic repositories.

A HostingService can specify forms for repository and bug tracker configuration.

It can also provide a list of repository “plans” (such as public repositories, private repositories, or other types available to the hosting service), along with configuration specific to the plan. These plans will be available when configuring the repository.

hosting_service_id = None[source]¶

The unique ID of the hosting service.

This should be lowercase, and only consist of the characters a-z, 0-9, _, and -.

New in version 3.0.16: This should now be set on all custom hosting services. It will be required in Review Board 4.0.

name = None[source]¶

plans = None[source]¶

supports_bug_trackers = False[source]¶

supports_post_commit = False[source]¶

supports_repositories = False[source]¶

supports_ssh_key_association = False[source]¶

supports_two_factor_auth = False[source]¶

supports_list_remote_repositories = False[source]¶

has_repository_hook_instructions = False[source]¶

visible = True[source]¶

Whether this service should be shown as an available option.

This should be set to False when a service is no longer available to use, and should be hidden from repository configuration. The implementation can then be largely stubbed out. Users will see a message in the repository configuration page.

New in version 3.0.17.

self_hosted = False[source]¶

repository_url_patterns = None[source]¶

client_class[source]¶

alias of HostingServiceClient

auth_form = None[source]¶

Optional form used to configure authentication settings for an account.

needs_authorization = False[source]¶

form = None[source]¶

fields = [][source]¶

repository_fields = {}[source]¶

bug_tracker_field = None[source]¶

supported_scmtools = [][source]¶

A list of SCMTools IDs or names that are supported by this service.

This should contain a list of SCMTool IDs that this service can work with. For backwards-compatibility, it may instead contain a list of SCMTool names (corresponding to database registration names).

This may also be specified per-plan in the plans.

Changed in version 3.0.16: Added support for SCMTool IDs. A future version will deprecate using SCMTool names here.

visible_scmtools = None[source]¶

A list of SCMTool IDs that are visible when configuring the service.

This should contain a list of SCMTool IDs that this service will show when configuring a repository. It can be used to offer continued legacy support for an SCMTool without offering it when creating new repositories. If not specified, all SCMTools listed in supported_scmtools are assumed to be visible.

If explicitly set, this should always be equal to or a subset of supported_scmtools.

This may also be specified per-plan in the plans.

New in version 3.0.17.

__init__(account)[source]¶

Initialize the hosting service.

Parameters:	account (reviewboard.hostingsvcs.models.HostingServiceAccount) – The account to use with the service.

is_authorized()[source]¶

Return whether or not the account is currently authorized.

An account may no longer be authorized if the hosting service switches to a new API that doesn’t match the current authorization records. This function will determine whether the account is still considered authorized.

Returns:	Whether or not the associated account is authorized.
Return type:	bool

get_password()[source]¶

Return the raw password for this hosting service.

Not all hosting services provide this, and not all would need it. It’s primarily used when building a Subversion client, or other SCMTools that still need direct access to the repository itself.

Returns:	The password.
Return type:	unicode

is_ssh_key_associated(repository, key)[source]¶

Return whether or not the key is associated with the repository.

If the given key is present amongst the hosting service’s deploy keys for the given repository, then it is considered to be associated.

Sub-classes should implement this when the hosting service supports SSH key association.

Parameters:	repository (reviewboard.scmtools.models.Repository) – The repository the key must be associated with. key (paramiko.PKey) – The key to check for association.
Returns:	Whether or not the key is associated with the repository.
Return type:	bool
Raises:	reviewboard.hostingsvcs.errors.SSHKeyAssociationError – If an error occured during communication with the hosting service.

associate_ssh_key(repository, key)[source]¶

Sub-classes should implement this when the hosting service supports SSH key association.

Parameters:	repository (reviewboard.scmtools.models.Repository) – The repository to associate the key with. key (paramiko.PKey) – The key to add to the repository’s list of deploy keys.
Raises:	reviewboard.hostingsvcs.errors.SSHKeyAssociationError – If an error occured during key association.

Raises:

reviewboard.hostingsvcs.errors.AuthorizationError – The credentials provided were not valid. reviewboard.hostingsvcs.errors.TwoFactorAuthCodeRequiredError – A two-factor authentication code is required to authorize this account. The request must be retried with the same credentials and with the two_factor_auth_code parameter provided.

check_repository(path, username, password, scmtool_class, local_site_name, *args, **kwargs)[source]¶

Checks the validity of a repository configuration.

This performs a check against the hosting service or repository to ensure that the information provided by the user represents a valid repository.

normalize_patch(repository, patch, filename, revision)[source]¶

Normalize a diff/patch file before it’s applied.

This can be used to take an uploaded diff file and modify it so that it can be properly applied. This may, for instance, uncollapse keywords or remove metadata that would confuse patch.

By default, this passes along the normalization to the repository’s SCMTool.
