As we are blocked on some breaking changes to be addressed before we can upgrade Prometheus to the latest master, this PR attempts to upgrade Prometheus upto this commit prometheus/prometheus@cd73b3d which hopefully does not have any breaking changes and helps the TSDB block based ingesters in Cortex :)

  • I added CHANGELOG entry for this change.

I would have expected go.sum file to have changed after mod tidy and mod vendor, but that is not the case. What is more worrying is that, go.mod and go.sum in upstream point to different commit. Upstream go.mod says b90be6f32a33 and go.sum says 1e64d757f711, and the CI picks up 1e64d757f711.

Marco pointed me out to the override in go.mod, makes sense now, removing it and trying

There's an overrided in go.mod replace which you should change as well.

Thanks 💪

Some suggestions, otherwise lgtm.

Also @codesome we usually put in CHANGELOG such update as it usually adds a lot. Do you think there was something significant we pulled with this.

Also we need to pull more often (:

Why not up to latest?

I guess then @krasi-georgiev want to take over?

Why not up to latest?

That has more breaking changes which will take time to fix here, and idea was to get some improvements from Prometheus soon. And yes, Krasi will take over after this one.

Also, I have some ugly hacks in place right now to fix some breaking changes. Once I fix the e2e tests, I plan to review stuff again and do a cleanup.
One such breaking change was replacing Rule with RuleNode in a RuleGroup upstream. The RuleNode upstream uses a yaml Node instead of a string like in Rule, which is painful when using it here, so I added a PromRuleGroup which does not use RuleNode.

Do you think there was something significant we pulled with this.

I will take a look at the changelogs and add the significate changes :)

Looks like essentially we have something wrong with flags still. e2e test:

=== CONT  TestReceive/hashring
Starting receive-1
receive-1: Error parsing commandline arguments: time: unknown unit d in duration 15d
receive-1: usage: thanos receive [<flags>]
receive-1: Accept Prometheus remote write API requests and write to local tsdb`

I guess its the modelDuration method after all. I will fall back to using them :)

@codesome @pracucci @pstibrany it unblocks Cortex I guess.
