GenericHordeAPISession

Bases: GenericHordeAPIManualClient

A client which can perform arbitrary horde API requests, but also keeps track of responses requiring follow up.

Use submit_request for synchronous requests, and submit_request for asynchronous requests.

This typically is the better class if you do not want to worry about handling any outstanding requests if your program crashes. This would be the case with most non-atomic requests, such as generation requests or anything labeled as async on the API.

should_retry 

should_retry(
    status_code: int,
    current_error_count: int,
    retry_after: float,
) -> bool

Determine if a request should be retried based on the status code and retry configuration.

Parameters:

  • status_code (int) –

    The HTTP status code returned by the request.

  • current_error_count (int) –

    The current number of errors encountered.

  • retry_after (float) –

    The time to wait before retrying the request.

Returns:

  • bool ( bool ) –

    True if the request should be retried, False otherwise.

should_retry 

should_retry(
    status_code: int,
    current_error_count: int,
    retry_after: float,
) -> bool

Determine if a request should be retried based on the status code and retry configuration.

Parameters:

  • status_code (int) –

    The HTTP status code returned by the request.

  • current_error_count (int) –

    The current number of errors encountered.

  • retry_after (float) –

    The time to wait before retrying the request.

Returns:

  • bool ( bool ) –

    True if the request should be retried, False otherwise.
