Julius Volz	3bfec97d46	Make the storage interface higher-level. ... See discussion in https://groups.google.com/forum/#!topic/prometheus-developers/bkuGbVlvQ9g The main idea is that the user of a storage shouldn't have to deal with fingerprints anymore, and should not need to do an individual preload call for each metric. The storage interface needs to be made more high-level to not expose these details. This also makes it easier to reuse the same storage interface for remote storages later, as fewer roundtrips are required and the fingerprint concept doesn't work well across the network. NOTE: this deliberately gets rid of a small optimization in the old query Analyzer, where we dedupe instants and ranges for the same series. This should have a minor impact, as most queries do not have multiple selectors loading the same series (and at the same offset).	8 years ago
Jonathan Boulle	38098f8c95	Add missing license headers ... Prometheus is Apache 2 licensed, and most source files have the appropriate copyright license header, but some were missing it without apparent reason. Correct that by adding it.	9 years ago

Brian Brazil	653ff71f1f	promql: Reduce flakiness of concurrency test	9 years ago
Brian Brazil	ce7f31e03c	promql: Bump sleep in query timeout test ... This test is flaky, I'm presuming the time.AfterFunc call is being delayed so the evaluation isn't getting cancelled.	9 years ago
Julius Volz	963ad82dcb	Fix "go vet" errors. ... I ignored all errors of the type "composite literal uses unkeyed fields". Most of them are wrong because of https://github.com/golang/go/issues/9171.	9 years ago
Laurie Malau	cdf38ab93a	Log runtime errors during query evaluation instead of panicking.	9 years ago
Fabian Reinartz	690b5f1575	Remove multi-statement queries ... This commit removes the possibility to have multi-statement queries which had no full support anyway. This makes the caller responsible for multi-statement semantics. Multiple tests are no longer timing-dependent.	9 years ago

Fabian Reinartz	9ab1f6c690	Limit maximum number of concurrent queries. ... A high number of concurrent queries can slow each other down so that none of them is reasonbly responsive. This commit limits the number of queries being concurrently executed.	10 years ago
Fabian Reinartz	fe935179cd	Stop routing rule statements through the engine.	10 years ago
Fabian Reinartz	5602328c7c	Refactor query evaluation. ... This copies the evaluation logic from the current rules/ package. The new engine handles the execution process from query string to final result. It provides query timeout and cancellation and general flexibility for future changes. functions.go: Add evaluation implementation. Slight changes to in/out data but not to the processing logic. quantile.go: No changes. analyzer.go: No changes. engine.go: Actually new part. Mainly consists of evaluation methods which were not changed. setup_test.go: Copy of rules/helpers_test.go to setup test storage. promql_test.go: Copy of rules/rules_test.go.	10 years ago
