Dylan Guedes	cf419d1cb8	Implement `LegacySample`, `LegacyLabelPair` proto messages (#5301 ) * Add LegacySample and modify protos to use it. * [Skip this commit] Regenerate protos. * Modify codebase to use LegacySample instead of Sample. For reference, take a look at PR https://github.com/grafana/loki/pull/5151. * Implement LegacyLabelPair. * Use new Legacy implementations accordingly. * Use LegacySample in compat tests. - Since `compat.go` was forked from Cortex, we can reliably change all mentions from `Sample` to `LegacySample` there.	4 years ago

Cyril Tovena	93f2b2d89b	Fixes split interval for metrics queries. (#3459 ) The step needs to be taken into account: - to be removed on each split end. - to not split queries that have a step lower than the split interval. The code is taken from Cortex but adjusted to keep the nanoseconds precision. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	5 years ago
Cyril Tovena	20ef66df65	Fixes a race in the scheduling limits. (#3417 ) * Fixes a race in the scheduling limits. Found out the hard way that sharding might not listen correctly to context and so still run queries after the upstream request ends. This can lead to panic when scheduling work which send on a closed channel. I've added a safe guard to wait for all jobs to end before ending the original request but also attemped to fix the sharding downstreamer to properly stop sending work when context is closed.
