Justin Lei	c16b6a0185	Handle native histograms in remote read Signed-off-by: Justin Lei <justin.lei@grafana.com>	2 years ago
Charles Korn	0a1de58f7e	Mark Histogram.(Positive\|Negative)Spans as non-nullable. As far as I understand it, we'd never expect to receive a nil span, and remote.spansProtoToSpans would panic if we received a nil span. Marking the fields as non-nullable also means the generated Golang code doesn't use pointers for these fields, reducing allocations. Signed-off-by: Charles Korn <charles.korn@grafana.com>	2 years ago

beorn7	87351f2318	prompb: Modify layout of histograms Note: This is deliberately an incompatible change. Since we have never used histograms in remote read/write yet, there is no point in keeping compatibility. This _is_, however, compatible to the state in the main branch. This commit flattens the bucket message into top-level fields. This has the disadvantage of now having two triples of fields prefixed with `negative_...` or `positive_...`. However, with this structure, we save one tag on the wire. And, perhaps more importantly, we mirror the structure of the `histogram.Histogram` Go type. This commit also adjusts `repeated` fields to use names in the plural form, as it is also the case for the fields that already existed. This also adds a doc comment to `HistogramProtoToHistogram` and changes its return type to a pointer (which is more convenient and probably more efficient).

Simon Pasquier	81c4248081	*: bump gRPC and protobuf dependencies (#5367 ) The goal is to remove almost all references to the golang.org/x/net/context package. github.com/gogo/protobuf => v1.2.1 google.golang.org/grpc => v1.19.1 github.com/grpc-ecosystem/grpc-gateway => v1.18.5 It also replaces github.com/cockroachdb/cmux by github.com/soheilhy/cmux because of [1] which fixes #3909 incidentally.

Bartek Plotka	c3434a39b7	proto: Allow reproducible proto generation. Current way of setting prometheus project to generate repo is tedious. If you just go install packages described in README.md it ends up with those (non buildable code) ``` ../../../prompb/remote.pb.go:61:34: undefined: "github.com/prometheus/prometheus/vendor/github.com/gogo/protobuf/proto".InternalMessageInfo ../../../prompb/remote.pb.go:109:33: undefined: "github.com/prometheus/prometheus/vendor/github.com/gogo/protobuf/proto".InternalMessageInfo ../../../prompb/remote.pb.go:164:34: undefined: "github.com/prometheus/prometheus/vendor/github.com/gogo/protobuf/proto".InternalMessageInfo ../../../prompb/remote.pb.go:214:27: undefined: "github.com/prometheus/prometheus/vendor/github.com/gogo/protobuf/proto".InternalMessageInfo ../../../prompb/remote.pb.go:284:33: undefined: "github.com/prometheus/prometheus/vendor/github.com/gogo/protobuf/proto".InternalMessageInfo ``` The issue is that the guide presented in proto folder is asking to install some GO packages. It does not mention from what version and there is strong mismatch between those used to generate proto and those that are vendored and used to run the code later... The particular outdated packages in vendor are: `github.com/gogo/protobuf` and `google.golang.org/grpc`. Just updating vendor would be not enough, as it would only tmp fix. I propose adding script that will parse version from vendor.json and install correct version. Changes: - Added script that uses packages in exactly the same version the Go code is build against later. - Regenerated proto with those pinned deps. - Updated REAMDE.md - Added `make proto`Current way of setting prometheus project to generate code from proto files is tedious.
