pyramid_retry

pyramid_retry is an execution policy for Pyramid that wraps requests and can retry them a configurable number of times under certain "retryable" error conditions before indicating a failure to the client.

See or docs/index.rst in this distribution for detailed documentation.

2.1.1 (2020-03-21)

• Ensure the threadlocals are properly popped if the activate_hook throws an error or the request body fails to read due to a client disconnect. See

2.1 (2019-09-30)

• Add exception and response attributes to the pyramid_retry.IBeforeRetry event. See

2.0 (2019-06-06)

• No longer call invoke_exception_view if the policy catches an exception. If on the last attempt or non-retryable then the exception will now bubble out of the app and into WSGI middleware. See

1.0 (2018-10-18)

• Support Python 3.7.
• Update the version we require for Pyramid to a non-prerelease so that pip and other tools don't accidentally install pre-release software. See

0.5 (2017-06-19)

• Update the policy to to track changes in Pyramid 1.9b1. This is an incompatible change and requires at least Pyramid 1.9b1. See

0.4 (2017-06-12)

• Add the mark_error_retryable function in order to easily mark certain errors as retryable for pyramid_retry to detect. See

• Add the IBeforeRetry event that can be subscribed to be notified when a retry is about to occur in order to perform cleanup on the environ. See

0.3 (2017-04-10)

• Support a retry.activate_hook setting which can return a per-request number of retries. See

• Configuration is deferred so that settings may be changed after config.include('pyramid_retry') is invoked until the configurator is committed. See

• Rename the view predicates to last_retry_attempt and retryable_error. See

• Rename pyramid_retry.is_exc_retryable to pyramid_retry.is_error_retryable. See

0.2 (2017-03-02)

• Change the default attempts to 3 instead of 1.
• Rename the view predicates to is_last_attempt and is_exc_retryable.
• Drop support for the tm.attempts setting.
• The retry.attempts setting is always set now in registry.settings['retry.attempts'] so that apps can inspect it.

0.1 (2017-03-01)

• Initial release.
