Phabricator maintenance

Scap decrease in time

Differential increase

things we have: debian packages
things we need:
- MW Core (need define CI reality and actually integrate CI into Differential)
- Ops Puppet

Browser test creation change (the matrix building)

defining and enforcing test ownership responsibilities

Not pulling from your repo (including MW Core) unless your tests are green, period. Want it to be deployed? Fix your tests. You own your code and tests.

First pass is to only block on what we already block on (ie: voting tests in Jenkins)

TODO: Chad or Tyler to send the "no more Trebuchet for new services, kthx" email to Ops

TODO: make a timeline

get a list of repos from ops/puppet
order by last deploy change, descending
schedule x repos per week over the quarter

tin$ find /srv/deployment -maxdepth 2 -wholename '*/*/*/*/*'|wc -l
58
tin$

Should be a list of everything: https://github.com/wikimedia/operations-puppet/blob/production/hieradata/common/role/deployment.yaml#L1 Which is 40 repos grepping operations/puppet for 'provider.*trebuchet' gives 30 (the truth is somewhere in between?)

browser tests discussion

when things start failing there are long gaps before diagnosis and then fixing
- people assume it's just an issue with CI or the tests themselves
how to put a little bit of pressure on people to diagnose/fix failed tests
integrate diagnosis of tests before train would put the pressure on people
if we do this we need a way to correlate failures and changes in code
- if we had a deploy dashboard, when it started and the commits in between, and the test status
- we could see if we're going to be in a good place before the train
can offer the pre-merge voting browser test job

Q3 goal/project check-in

Reduce CI Wait time

KPI: https://grafana.wikimedia.org/dashboard/db/releng-kpis?panelId=2&fullscreen

Migrate remaining CI jobs to Nodepool - task T119138

php composer (Zend and HHVM) - task T119139
as many miscellaneous jobs as possible - task T119140

Migrate Jenkins to Jessie - task T124121

Antoine:

Looot of reviews
Lurking at daily browser tests refactoring
Nodepool had files corrupted
Nodepool instances hiera is badly configured
Nodepool upgrade this 7th march at 20:00 UTC to speed up deletion (faster pool replenishment, might grow pool as well)

Consolidate deploy tools

Migrate MediaWiki to scap3 - task T114313

Q2 Quarterly Goal hold over: Migrate all Service team owned services and MW deploys to scap3 - https://phabricator.wikimedia.org/T109926

Differential Migration

https://etherpad.wikimedia.org/p/diffuerential-weekly

Integrate Differential with our Continuous Integration infrastructure - task T31

build debian packages from differential: https://integration.wikimedia.org/ci/job/beta-build-deb/

Shepherd the RFC - task T119908

Garner early adopter projects (goal: 1 project per WMF "team")
