Julius Volz	9b6d69610a	Fix various typos in comments. Helpfully reported by https://goreportcard.com/report/github.com/prometheus/prometheus :)	9 years ago
Brian Brazil	9d0112d7cf	Add without aggregator modifier. This has the advantage that the user doesn't need to list all labels they want to keep (as with "by") but without having to worry about inconsistent labels as when there's only one time series (as with "keeping_common"). Almost all aggregation should use this rather than the existing two options as it's much less error prone and easier to maintain due to not having to always add in "job" plus whatever other common job-level labels you have like "region".	9 years ago
Brian Brazil	89760dd77d	Handle NaN for min/max. Similar to topk and sort, prefer not returning NaN where possible.	9 years ago
Fabian Reinartz	e3b6ec9784	Switch to common/log	9 years ago
Brian Brazil	29e8dc2c49	promql: Add 'bool' modifier to comparison functions When doing comparison operations on vectors, filtering sometimes gets in the way and you have to go to a fair bit of effort to workaround it in order to always return a result. The 'bool' modifier instead of filtering returns 0/1 depending on the result of the compairson. This is also a prerequisite to removing plain scalar/scalar comparisons, as it maintains the current behaviour under a new syntax.	9 years ago
Julius Volz	077a753e6b	Merge pull request #1006 from prometheus/true-values promql: Remove interpolation of vector values.	9 years ago
Fabian Reinartz	d6b8da8d43	Switch promql types to common/model	9 years ago
Brian Brazil	fb585e4591	promql: Remove interpolation of vector values. The current behaviour produces values that are not from rules or scrapes. So if for example I have a boolean 0/1 it can be returned as 0.2344589. This prevents a number of advanced use cases, introduces race conditions and can produce misleading graphs.	9 years ago
Fabian Reinartz	1535ef1457	Replace metric.SamplePair with model.SamplePair	9 years ago
Fabian Reinartz	438e232c9b	Fix grouping of import blocks	9 years ago
Fabian Reinartz	306e8468a0	Switch from client_golang/model to common/model	9 years ago
Laurie Malau	cdf38ab93a	Log runtime errors during query evaluation instead of panicking.	9 years ago
Julius Volz	27ed874358	Implement label_replace() Implements part of https://github.com/prometheus/prometheus/issues/959.	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	579fdf65e2	Implement unary expression for vector types. Closes #956	9 years ago
Fabian Reinartz	3d67d75935	promql: implement JSON array format for scalar and string	10 years ago
Fabian Reinartz	77e8983221	promql: add MarshalJSON method for SamplePair	10 years ago
Fabian Reinartz	70d7a987a7	promql: add json tags, fix query constructor.	10 years ago
Fabian Reinartz	fe301d7946	promql: remove global flags	10 years ago
Fabian Reinartz	c32ae22119	promql: fix missing metric in range results.	10 years ago
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.	10 years ago
Fabian Reinartz	0de6edbdfc	Move pkg/ to util/	10 years ago
Fabian Reinartz	ccf51b132e	Move stats package to pkg/stats	10 years ago
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.	10 years ago
Fabian Reinartz	ac4d63b833	Merge pull request #689 from prometheus/fabxc/qltest Add basic testing language, migrate tests	10 years ago
Fabian Reinartz	6321964738	Add parsing and execution of new test format. This commit adds a new test structure that parses and executes the new testing language.	10 years ago
Fabian Reinartz	ce487f763e	Simplify vector binary evaluation logic	10 years ago
Fabian Reinartz	8a109e061b	Extract OR operation into own eval method.	10 years ago
Fabian Reinartz	2c3e9e2e87	Extract AND operation into own eval method.	10 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	d59d1cb2c1	Fix Error() methods.	10 years ago
Fabian Reinartz	fe935179cd	Stop routing rule statements through the engine.	10 years ago
Fabian Reinartz	25cdff3527	Remove `name` arg from `Parse*` functions, enhance parsing errors.	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
