@trivikr does landing this result in it being deployed or is it just a reflection of what you deployed yourself?

Just want to understand the context of what it means to land the PR.

does landing this result in it being deployed

No, AFAIK. It doesn't appear to be like automation is set up for deploying updates in metrics processing, and it needs to be manually deployed.

We can discuss setting up automation using terraform/pulumi for example, after the download stats issue is debugged and fixed #3697.

I've been updating stuff as soon as I come across one. Here is an example flow:

• Fix to remove most commonly occurring error: metrics: skip empty lines in process cloudflare #3765
• Getting required permissions to deploy Give GCP access to trivikr with a "Editor" role for Container Registry and Cloud Run #3774
• Documenting the current setup at the best of my knowledge metrics: add documentation for updating Cloud Run #3779

I would like to make some other changes too if maintainers agree, like moving to Artifact Registry, updating dependencies, moving from express to fastify, adding unit tests with Node.js Test Runner, adding CI etc. But this can be done after downloads stats are fixed.

is it just a reflection of what you deployed yourself?

No. It's just a proposal from the PR author for making changes in metrics source code.
Once merged, following the project governance for approvals and 48/72 hours, the author (ideally) has to deploy it till automation is set up.

what it means to land the PR.

As of now, I think it currently means the Build WG accepts the proposal mentioned in the PR.

This change is no longer needed, since Unexpected end of JSON input is no longer thrown after merging and deploying #3765
