Thanks for the fix!

https://gitlab.wikimedia.org/repos/mediawiki/services/ipoid/-/jobs/342362 is an example pipeline failure.

This regressed during T370438 work, we'll tackle it.

I've prepared a simple tracing library as discussed above.

Yeah, there are some additional examples at https://github.com/open-telemetry/opentelemetry-proto/blob/v1.3.2/examples/trace.json. I'll look into creating a PS this week about implementing a simple OTEL tracing lib from scratch.

With regards to (1) -- the OTEL spec is bespoke, but the trace data format is less so. If we want to, we could probably create a simpler client as suggested with a reasonable effort. While it wouldn't conform to the spec, that shouldn't matter too much in the big picture of things as long as it is conformant when it comes to exporting data and propagating trace context.

Thanks, looks good!

Thanks Andre!

We should ideally add a regression test for this, which I have been working on as part of a corresponding patch. I'll submit that now.

This regressed in https://gerrit.wikimedia.org/r/c/mediawiki/extensions/CentralAuth/+/1019394 which accidentally removed the IGNORE flag from storeGlobalData.
