Greplin Twisted Utilities

Useful utilities for Twisted development.

Status:

This is a very early stage project. It works for our needs. We haven't verified it works beyond that. Issue reports and patches are very much appreciated!

Pre-requisites:

Twisted

Installation

git clone https://github.com/Greplin/greplin-twisted-utils.git

cd greplin-twisted-utils

python setup.py install

Components

greplin.defer

• Context management - allows setting context variables that persist across asynchronous events. This is highly experimental!

• Deferred events - pub/sub model for events.

• Lazy map - map that lazily computes its values, possibly requiring asynchronous computation.

• Deferred queues

• Retry logic for deferred requests that may fail transiently

• Time - simple utilities for deferred objects that fire after a specified time

• Deferred wrapper - allows for success / failure to be handled at the very end of the callback chain.

greplin.net

• DNS cache - avoid repeatedly resolving the same DNS names

greplin.testing

• Mock implementation of greplin.defer.time
