Fabian Reinartz	749ae450c5	promql: add runbook to alert statement. ... This commit adds the RUNBOOK keyword to alert statements. The field is optional and expected to be a link.	10 years ago
Fabian Reinartz	94cd321be1	promql: error if all label matchers are empty.	10 years ago
Julius Volz	5e2d1c1464	Deprecate `keeping_extra`, rename it to `keep_common`. ... `keep_common` is more in line with the function name `drop_common_labels()` terminology-wise, and also more in line with `group_left`/`group_right` (no `...ing` verb suffix). We could also go the full way and call it `keep_common_labels`. That would have the benefit of being even more consistent with the function `drop_common_labels()` and would be more explanatory, but it also seems quite long.	10 years ago
Fabian Reinartz	319068a7a6	promql: fix parsing ambiguity for serial repetitions	10 years ago
Fabian Reinartz	03094eff04	Migrate parsing error tests. ... The promql_test checks failure of various bad syntaxed queries. Those are moved into the parser tests as the new testing language only deals with valid queries.	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	a236c01457	Add time series description parsing. ... This commit adds parsing of time series description to the exisiting query language parser. Time series descriptions are defined by a metric followed by a sequence of values.	10 years ago
Fabian Reinartz	8707c54508	Fix single quote parsing, add tests	10 years ago
Fabian Reinartz	279831cdf1	Fix and improve parsing error output.	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
Fabian Reinartz	32b7595c47	Create promql package with lexer/parser. ... This commit creates a (so far unused) package. It contains the a custom lexer/parser for the query language. ast.go: New AST that interacts well with the parser. lex.go: Custom lexer (new). lex_test.go: Lexer tests (new). parse.go: Custom parser (new). parse_test.go: Parser tests (new). functions.go: Changed function type, dummies for parser testing (barely changed/dummies). printer.go: Adapted from rules/ and adjusted to new AST (mostly unchanged, few additions).	10 years ago
