API documentation for storage.retry module.

Classes

ConditionalRetryPolicy

ConditionalRetryPolicy(retry_policy, conditional_predicate, required_kwargs)

A class for use when an API call is only conditionally safe to retry.

This class is intended for use in inspecting the API call parameters of an API call to verify that any flags necessary to make the API call idempotent (such as specifying an if_generation_match or related flag) are present.

It can be used in place of a retry.Retry object, in which case _http.Connection.api_request will pass the requested api call keyword arguments into the conditional_predicate and return the retry_policy if the conditions are met.

Parameters
Name	Description
retry_policy	class:google.api_core.retry.Retry A retry object defining timeouts, persistence and which exceptions to retry.
conditional_predicate	callable A callable that accepts exactly the number of arguments in required_kwargs, in order, and returns True if the arguments have sufficient data to determine that the call is safe to retry (idempotent).
required_kwargs	list(str) A list of keyword argument keys that will be extracted from the API call and passed into the conditional predicate in order.
