hashar added a comment to T128188: Make CI run Varnish VCL tests.

The task is from 2016, and I most probably filed it as a placeholder to track effort to enhance test coverage on various repositories. We were on a rampage to add more tests everywhere at the time.

Tgr added a comment to T113817: Add request_id to webrequest logs as well as other event records ingested into Hadoop.

The task was about connecting webrequest data and MediaWiki API logs (or more generally, MediaWiki logs), though, and webrequest data does not have the request ID as far as I know.

Going to resolve this instead of declining. For EventBus generated events, including mediawiki.api-request, x_request_id is set in events as the meta.request_id field.

Mholloway added a comment to T109776: Tilerator should purge Varnish cache.

Let's leave it open for now. We may have some dedicated maps maintenance capacity in the next couple quarters and would want to address content freshness as part of that effort. That said, I imagine we would end up doing something more like T109776#3086227 in the end rather than purging the content from Varnish/ATS directly.
