beorn7	4e3abc6cbf	Simply use `math.Mod(float64, float64)` after all ... This circumvents all the problems with int overflow, plus it is what was originally intended.	8 years ago
beorn7	5cf5bb427a	Check for int64 overflow when converting from float64	8 years ago
beorn7	07f1bdfe94	Fix MOD binop for scalars and vectors ... Previously, a floating point number that would round down to 0 would cause a "division by zero" panic.	8 years ago
Brian Brazil	3b89616d82	Allow on, ignoring, by and without wit empty laberls. ... This offers new semantics in allowing on() for matching two single-element vectors with no known common labels. Previosuly this was often done using on(dummy). This also allows making it explict that you meant to do an aggregation without labels via by(). Fixes #1597.	9 years ago
royels	2fdc5717a3	promql: add power binary operation	9 years ago
Brian Brazil	ef55fd6176	Add unittest for using a metric for thresholds with group_left.	9 years ago
Brian Brazil	d991f0cf47	For many-to-one matches, always copy label from one side. ... This is a breaking change for everyone using the machine roles labeling approach.	9 years ago
Brian Brazil	768d09fd2a	Change on+group_* to take copy from the one side. ... If the label doesn't exist on the one side, it's not copied. All labels on the many inside are included, this is a breaking change but likely low impact.	9 years ago
Brian Brazil	d1edfb25b3	Add support for OneToMany with IGNORING. ... The labels listed in the group_ modifier will be copied from the one side to the many side. It will be valid to specify no labels. This is intended to replace the existing ON/GROUP_* support.,	9 years ago
Brian Brazil	1d08c4fef0	Add 'ignoring' as modifier for binops. ... Where 'on' uses the given labels to match, 'ignoring' uses all other labels to match. group_left/right is not supported yet.	9 years ago
Brian Brazil	f5084ab1c5	Add tests for group_left/group_right	9 years ago
Tobias Schmidt	8cc86f25c0	Implement relative complement set operator "unless" ... The `unless` set operator can be used to return all vector elements from the LHS which do not match the elements on the RHS. A use case is to return all metrics for nodes which do not have a specific role: node_load1 unless on(instance) chef_role{role="app"}	9 years ago
Tobias Schmidt	4c3dc25e35	Fix whitespace in promql test data	9 years ago
Brian Brazil	8788701ce7	Add test for incorrect behaviour	9 years ago
Brian Brazil	39d556f0d5	Move all the operator tests into one file	9 years ago
Brian Brazil	b7ef0b45e8	Break aggregation tests out. Add missing tests.	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
