Douglas Camata	47819fef01	Merge branch 'main' of github.com:prometheus/prometheus into document-and-test-relabel-memory-reuse ... Signed-off-by: Douglas Camata <159076+douglascamata@users.noreply.github.com>	1 year ago
Bryan Boreham	7a48a266b6	labels: respect Set after Del in Builder (#12322) ... * labels: respect Set after Del in Builder The implementations are not symmetric between `Set()` and `Del()`, so we must be careful. Add tests for this, both in labels and in relabel where the issue was reported. Also make the slice implementation consistent re `slices.Contains`.

Bryan Boreham	b987afa7ef	labels: simplify call to get Labels from Builder ... It took a `Labels` where the memory could be re-used, but in practice this hardly ever benefitted. Especially after converting `relabel.Process` to `relabel.ProcessBuilder`. Comparing the parameter to `nil` was a bug; `EmptyLabels` is not `nil` so the slice was reallocated multiple times by `append`. Lastly `Builder.Labels()` now estimates that the final size will depend on labels added and deleted. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
Bryan Boreham	11d019ed5a	relabel: keep intermediate results in labels.Builder ... Save work converting between Builder and Labels. Also expose ProcessBuilder, so callers can supply a Builder. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
Renning Bruns	5ec1b4baaf	make hashmod a lot easier to read and a little faster (#11551) ... Previous code was effectively doing BigEndian.Uint64, so call that and save time. An md5.Sum result is always 16 bytes. The first 8 are not used in the result, just as before. Signed-off-by: Renning Bruns <ren@renmail.net>	2 years ago

Bryan Boreham	8b863c42dd	Optimise relabeling by re-using memory (#11147) ... * model/relabel: Add benchmark Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * model/relabel: re-use Builder across relabels Saves memory allocations. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * labels.Builder: allow re-use of result slice This reduces memory allocations where the caller has a suitable slice available. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * model/relabel: re-use source values slice To reduce memory allocations. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Unwind one change causing test failures Restore original behaviour in PopulateLabels, where we must not overwrite the input set. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * relabel: simplify values optimisation Use a stack-based array for up to 16 source labels, which will be the vast majority of cases.
