Trevor Whitney	4a56445686	Upgrade `golangci-lint` and fix linting errors (#9601 ) What this PR does / why we need it: Upgrade `golangci-lint` and fixes all the errors. The upgrade includes some stricter linting.	2 years ago
Peter Štibraný	90a1d4593e	Update Prometheus dependency (#9205 )	2 years ago
Travis Patterson	37c0b3dec2	Allow math on errors (#8823 ) Currently metric expressions will fail if they contain the parser error label `__error__`. There are cases where you may want to count errors. For example, `sum(count_over_time({foo="bar"} \| json \| __error__= "JSONParserErr" [$__interval]))` to see how many of your logs are unparsable JSON. This pr uses `ParseHint` to determine whether the `__error__` label was requested in the query and, if it was, do math on it like any other query. Parse hints are only included in VectorAggregations so the label used to signal whether or not to keep errors is never seen by a user. All other operations remain unaffected	2 years ago

Jesus Vazquez	db9dbe8e1d	Bump prometheus dependency (#6403 ) * Bump prometheus dependency We had to add a replace of prometheus in go mod because thanos is importing an older version and then replacing it. * Undo textparser.New variable mismatch * modtimevfs path update * Fix labels withlabels and withoutlabels usages WithoutLabels and WithLabels methods have dissappeared. Now labels.NewBuilder has to be used. * Fix RuleManager interface for Update() Update now accepts a new param called ruleGroupPostProcessFunc which is an optional function to be executed after rule group processing. In this case I've set it to nil in the usages i've found. * NewQueryRange now accepts QueryOpts The NewQueryRange function now accepts QueryOptions so I had to update all the calls. I've set the opts to nil since we're not using them. * gofmt	3 years ago

Cyril Tovena	e21d6edc10	Fixes 500 in the querier when returning multiple errors. (#3348 ) This correctly implement the `Is` error interface and uses the `util.MultiError` everywhere we need it.

Cyril Tovena	3f0800dc44	Add function label_replace. (#3047 ) You might be wondering why do we need label_replace when we already have label_format. Well for two reasons: 1. It's nice to have something similar to Prometheus, so users building metric queries will feel right at home. 2. Interestingly, they are quite different in how they execute. label_format executes for every log line, however label_replace execute for every sample. Since you aggregate log lines into sample then label_replace is way more efficient at scale. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	5 years ago
