When a provider is at quota, we pause it, and paused means paused. That means we don't do anything with any other requests. Unfortunately, that includes requests that the given provider can't even handle. So if a provider pauses because it is at quota while other providers continue to operate, if a request for a node type that no providers can handle arrives, then that request will remain outstanding until this provider becomes unpaused and can decline it. Requests shouldn't need to wait so long to be declined by providers which can never under any circumstances handle them. To address this, we will now run the assignHandlers method whether we are paused or not. Within assignHandlers, we will process all requests regardless of whether we are paused (but we won't necessarily accept them yet). We will decide whether a request will be declined or not, and if it will be declined, we will do so regardless of whether we are paused. Finally, only if we are unpaused and do not expect to decline the request will we accept it. Change-Id: Ied9e4577670ea65b1d5ecfef95a7f837a7b6ac61
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.
