Fabian Reinartz cb10ceac18 promql: allow scalar expressions in range queries, improve errors. 
These changes allow to do range queries over scalar expressions.
Errors on bad types for range queries are now raised on query creation
rather than evaluation.

beorn7 3b9c421a69 Weed out all the [Gg]et* method names. 
The only exception is getNumChunksToPersist to avoid naming the struct
member numChunksToPersist in a weird way.

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.

Fabian Reinartz 25cdff3527 Remove `name` arg from `Parse*` functions, enhance parsing errors. 2015-04-29 16:38:41 +02:00
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.
