exception cowbird.config.ConfigError

Bases: RuntimeError

Generic error during configuration loading.

Initialize self. See help(type(self)) for accurate signature.

exception cowbird.config.ConfigErrorInvalidTokens

Bases: ConfigError

Config error specific to invalid SINGLE_TOKEN or MULTI_TOKEN tokens.

Initialize self. See help(type(self)) for accurate signature.

exception cowbird.config.ConfigErrorInvalidServiceKey

Bases: ConfigError

Config error for invalid service keys.

Initialize self. See help(type(self)) for accurate signature.

exception cowbird.config.ConfigErrorInvalidResourceKey

Bases: ConfigError

Config error for invalid resource keys.

cowbird.config._load_config(path_or_dict: Union[str, cowbird.typedefs.ConfigDict], section: str, allow_missing: bool = False) → cowbird.typedefs.ConfigDict

Loads a file path or dictionary as YAML/JSON configuration.

cowbird.config.get_all_configs(path_or_dict: Union[str, cowbird.typedefs.ConfigDict], section: str, allow_missing: bool = False) → List[cowbird.typedefs.ConfigDict]

Loads all configuration files specified by the path (if a directory), a single configuration (if a file) or directly returns the specified dictionary section (if a configuration dictionary). :returns:

• list of configurations loaded if input was a directory path

• list of single configuration if input was a file path

• list of single configuration if input was a JSON dict

• empty list if none of the other cases where matched

Note

Order of file loading will be resolved by alphabetically sorted filename if specifying a directory path.

cowbird.config._expand_all(config: cowbird.typedefs.ConfigDict) → cowbird.typedefs.ConfigDict

Applies environment variable expansion recursively to all applicable fields of a configuration definition.

cowbird.config.validate_services_config_schema(services_cfg: cowbird.typedefs.ConfigDict) → None

Validates the schema of the services section found in the config.

cowbird.config.validate_sync_perm_config_schema(sync_cfg: cowbird.typedefs.ConfigDict) → None

Validates the schema of the sync_permissions section found in the config.

cowbird.config.validate_and_get_resource_info(res_key: str, segments: List[cowbird.typedefs.ConfigSegment]) → cowbird.typedefs.ConfigResTokenInfo

Validates a resource_key and its related info from the config and returns some resource info relevant to the config mapping validation.

Returned info contains the following: - if the resource uses a MULTI_TOKEN in its resource_path - the list of named tokens found in the resource_path

cowbird.config.validate_bidirectional_mapping(mapping: str, res_info: Dict[str, cowbird.typedefs.ConfigResTokenInfo], res_key1: str, res_key2: str) → None

Validates if both resources of a bidirectional mapping respect validation rules.

Both should either use MULTI_TOKEN or not use it and both should use exactly the same named tokens.

cowbird.config.validate_unidirectional_mapping(mapping: str, src_info: cowbird.typedefs.ConfigResTokenInfo, tgt_info: cowbird.typedefs.ConfigResTokenInfo) → None

Validates if both source and target resource of a unidirectional mapping respect validation rules.

Source resource should use MULTI_TOKEN if target uses it, and source resource should include all named tokens found in the target resource.

cowbird.config.get_mapping_info(mapping: str) → Tuple[Union[str, Any], Ellipsis]

Obtain the different info found in a mapping string from the config.

Returns the following matching groups : (res_key1, permission1, direction, res_key2, permission2)

cowbird.config.get_permissions_from_str(permissions: str) → List[str]

Returns a tuple of all permissions found in a string.

Used for permission strings found in the config, which can either be a single permission or a list of permissions.

cowbird.config.validate_sync_mapping_config(sync_cfg: cowbird.typedefs.ConfigDict, res_info: Dict[str, cowbird.typedefs.ConfigResTokenInfo]) → None

Validates if mappings in the config have valid resource keys and use tokens properly.

cowbird.config.validate_sync_config(sync_cfg: cowbird.typedefs.ConfigDict) → None

cowbird.config.validate_sync_config_services(sync_cfg: cowbird.typedefs.ConfigDict, available_services: List) → None

Validates if all services used in the sync config are actual available services.

All services should correspond to actual services available in Magpie.
