is happening somewhere outside of quibble afaict. @Krinkle mentioned that it could have something to do with filtering, i.e. it's trying to look at too many files at once.

Yes, see my comment on https://gerrit.wikimedia.org/r/#/c/427698/ – MW core's too big for a naïve phpcs run (which looks at all the files), so mediawiki-core-phpcs-docker previously would run differently…

No space left on device

The Docker slaves have their /var/lib/docker on / which is only 20GBytes large. Puppet should provision the docker directory under the extended disk space. And we need slaves with larger disk.

For phpcs, I made it to run on all files whenever composer.json or phpcs.xml is changed. Otherwise composer test is only run against file that got changed in the patch.

The step times out with:

The process "composer phpcs '.'" exceeded the timeout of 300 seconds.

That is my fault really. The Nodepool based jobs invoke composer test with COMPOSER_PROCESS_TIMEOUT=600:

- builder:
    name: composer-test
    builders:
     - shell: |
        cd "{dir}"
        [[ -f "composer.json" ]] || exit 0
        COMPOSER_PROCESS_TIMEOUT=600 composer --ansi test
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
