class linotp.controllers.maintenance.MaintenanceController(name, install_name='', **kwargs)

Bases: BaseController

The maintenance controller is an internal interface for maintainers to change certain parameters (such as log levels) at runtime

after_request_funcs: t.Dict[ft.AppOrBlueprintKey, t.List[ft.AfterRequestCallable]]

A data structure of functions to call at the end of each request, in the format {scope: [functions]}. The scope key is the name of a blueprint the functions are active for, or None for all requests.

To register a function, use the after_request() decorator.

This data structure is internal. It should not be modified directly and its format may change at any time.

before_request_funcs: t.Dict[ft.AppOrBlueprintKey, t.List[ft.BeforeRequestCallable]]

A data structure of functions to call at the beginning of each request, in the format {scope: [functions]}. The scope key is the name of a blueprint the functions are active for, or None for all requests.

To register a function, use the before_request() decorator.

This data structure is internal. It should not be modified directly and its format may change at any time.

check_status()

GET, POST /maintenance/check_status

Deprecated since version 3.2: Requests using HTTP POST method (because it is only reading data). This endpoint will only be available via HTTP GET method in the future.

simple check if LinOTP backend services are up and running

support for checking that the Config database could be accessed

Returns:

a json result with a boolean status and request result

Raises:

Exception – if an error occurs an exception is serialized and returned

deferred_functions: t.List[DeferredSetupFunction]
error_handler_spec: t.Dict[ft.AppOrBlueprintKey, t.Dict[t.Optional[int], t.Dict[t.Type[Exception], ft.ErrorHandlerCallable]]]

A data structure of registered error handlers, in the format {scope: {code: {class: handler}}}. The scope key is the name of a blueprint the handlers are active for, or None for all requests. The code key is the HTTP status code for HTTPException, or None for other exceptions. The innermost dictionary maps exception classes to handler functions.

To register an error handler, use the errorhandler() decorator.

name: str
setLogLevel()

POST /maintenance/setLogLevel

set the log level of a certain logger which is identified by the url parameter loggerName.

POST /maintenance/setLogLevel loggerName=linotp.lib.user level=10

(sets the log level of the user library to DEBUG) if loggerName is omitted, the root logger is assumed.

Parameters:
  • loggerName – the name of the logger

  • level – the logging level

Returns:

a json result with a boolean status and request result

Raises:

Exception – if an error occurs an exception is serialized and returned

teardown_request_funcs: t.Dict[ft.AppOrBlueprintKey, t.List[ft.TeardownCallable]]

A data structure of functions to call at the end of each request even if an exception is raised, in the format {scope: [functions]}. The scope key is the name of a blueprint the functions are active for, or None for all requests.

To register a function, use the teardown_request() decorator.

This data structure is internal. It should not be modified directly and its format may change at any time.

template_context_processors: t.Dict[ft.AppOrBlueprintKey, t.List[ft.TemplateContextProcessorCallable]]

A data structure of functions to call to pass extra context values when rendering templates, in the format {scope: [functions]}. The scope key is the name of a blueprint the functions are active for, or None for all requests.

To register a function, use the context_processor() decorator.

This data structure is internal. It should not be modified directly and its format may change at any time.

url_default_functions: t.Dict[ft.AppOrBlueprintKey, t.List[ft.URLDefaultCallable]]

A data structure of functions to call to modify the keyword arguments when generating URLs, in the format {scope: [functions]}. The scope key is the name of a blueprint the functions are active for, or None for all requests.

To register a function, use the url_defaults() decorator.

This data structure is internal. It should not be modified directly and its format may change at any time.

url_value_preprocessors: t.Dict[ft.AppOrBlueprintKey, t.List[ft.URLValuePreprocessorCallable]]

A data structure of functions to call to modify the keyword arguments passed to the view function, in the format {scope: [functions]}. The scope key is the name of a blueprint the functions are active for, or None for all requests.

To register a function, use the url_value_preprocessor() decorator.

This data structure is internal. It should not be modified directly and its format may change at any time.

view_functions: t.Dict[str, t.Callable]

A dictionary mapping endpoint names to view functions.

To register a view function, use the route() decorator.
