Tobias Schmidt	1a91cd6e09	Rename matrix to range selector in external error messages The documentation speaks about range vectors and range vector selectors. This change does not fix all issues, we might still expose the term "Matrix" in error messages using %T.	9 years ago
Tobias Schmidt	411ca4dba1	Consolidate offset modifier parsing Remove duplicated offset modifier parsing and ensure offset can only appear at the end of a selector statement.	9 years ago
Fabian Reinartz	6b4a6962d2	Support old alerting rule syntax	9 years ago
Fabian Reinartz	4209ec6864	Change WITH keyword to LABELS	9 years ago
Fabian Reinartz	af3a6661ed	Implement new alerting rule syntax	9 years ago
Brian Brazil	c36961130b	promql: Remove scalar/scalar comparisons. This change is breaking, use the 'bool' modifier for such comprisons. After this change all comparisons without 'bool' will filter, and all comparisons with 'bool' will return 0/1. This makes the language more consistent and orthogonal, and ultimately easier to learn and use. If we ever figure out sane semantics for filtering scalar/scalar comparisons we can add them in, which will most likely come out of how the new vector() function is used.	9 years ago
Julius Volz	46c5260761	Support escape sequences in strings and add raw strings. This adapts some functionality from the Go standard library for string literal lexing and unquoting/unescaping. The following string types are now supported: Double- or single-quoted strings: These support all escape sequences that Go supports in double-quoted string literals. The difference is that Prometheus also has single-quoted strings (instead of single-quoted runes in Go). Raw newlines are not allowed. Backtick-quoted raw strings: Strings quoted in backticks are treated as raw strings just like in Go and may contain raw newlines and other special characters directly. Fixes https://github.com/prometheus/prometheus/issues/1122 Fixes https://github.com/prometheus/prometheus/issues/1121	9 years ago
Fabian Reinartz	171f50706a	Fix unkeyed field errors.	9 years ago
Brian Brazil	9ec11b1847	Merge pull request #1049 from prometheus/bool-nofilter promql: Add 'bool' modifier to comparison functions	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	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
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
Brian Brazil	296f551418	Merge pull request #1014 from prometheus/scalar-rules rules: Allow recorded rules expressions to be scalars.	9 years ago
Brian Brazil	e6a67476c2	rules: Allow recorded rules expressions to be scalars. This is useful if you want to build up a constant metric, such as a set of alert thresholds that vary by label value.	9 years ago
Laurie Malau	cdf38ab93a	Log runtime errors during query evaluation instead of panicking.	9 years ago
Fabian Reinartz	579fdf65e2	Implement unary expression for vector types. Closes #956	9 years ago
Fabian Reinartz	adf109795c	forbid unexpected (runtime) errors in parse tests	9 years ago
Fabian Reinartz	c20e25f718	Add missing check for nil expression	9 years ago
Fabian Reinartz	5279d50d92	Handle parser runtime panics gracefully	9 years ago
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
