The launcher implementation assumed that only one request handler will be paused at any given point in time. However, this is not true when e.g. the request handler accepts multiple requests that all run into a quota limit during launch. The consequence of this is that the pool is unpaused too early and we might accept other node requests until the provider is paused again. This could lead to a starvation of earlier paused handlers as they were fulfilled in a LIFO fashion. To fix this edge case we will store paused request handlers in a set and only unpause the provider when there are no paused handlers anymore. Paused handlers are now also run in priority order.

Nodepool
Nodepool is a system for managing test node resources. It supports launching single-use test nodes from cloud providers as well as managing access to pre-defined pre-existing nodes. Nodepool is part of a suite of tools that form a comprehensive test system, including Zuul.
The latest documentation for Nodepool is published at: https://zuul-ci.org/docs/nodepool/
The latest documentation for Zuul is published at: https://zuul-ci.org/docs/zuul/
Getting Help
There are two Zuul-related mailing lists:
- zuul-announce
-
A low-traffic announcement-only list to which every Zuul operator or power-user should subscribe.
- zuul-discuss
-
General discussion about Zuul, including questions about how to use it, and future development.
You will also find Zuul developers in the #zuul channel on Freenode IRC.
