tl;dr: The new scap version is live in production. It has canary
deploys.
Scap v.3.2.2-1 was deployed to production today. There are some new
internal improvements as well as some that are user-facing.
The improvements you'll probably notice are:
* Tab completion works for scap subcommands(!)
* Canary checks for MediaWiki deployments
Canary deployments:
1. Sync your change(s) to the api and appserver canary hosts
2. Wait (20 seconds) for traffic to hit those host
3. If there isn't a large increase in the error rate on those hosts
(10x), release your changes to the remainder of the fleet.
If, for whatever reason, you find yourself in a position where you don't
care about the error-rate change on canary nodes, use the --force flag,
i.e.:
scap sync-file --force README 'Important README update'
Please report any problems in a phab ticket tagged with "Scap3" or in
#wikimedia-releng in IRC on freenode.
<3,
Your Hometown Release Engineers
