Callum Styan	5bb7f00d00	change labelset comparison in promql engine to avoid false positive during detection of duplicates (#7058) ... * Use go1.14 new hash/maphash to hash both RHS and LHS instead of XOR'ing which has been resulting in hash collisions.

Brian Brazil	a9ed3b980d	Optimise labels.Compare (#6539) ... strings.Compare isn't meant to be used, and this way we save one comparison which is thus very slightly cheaper. benchmark old ns/op new ns/op delta BenchmarkPostingsForMatchers/Head/n="1"-4 236305440 233515705 -1.18% Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	5 years ago
Julius Volz	ae93bae88f	Fix: exclude metric name in labels.MatchLabels() (#6523) ... This function is only used in one place to format an error message when encountering multiple matches on the "one" side of a one-to-many/many-to-one vector match, which is probably why nobodoy has noticed this before. The hashing is already done correctly and excludes the metric name label when using the "ignoring" matching modifier. Signed-off-by: Julius Volz <julius.volz@gmail.com>	5 years ago

Brian Brazil	4addee2bee	Fix honor_labels for empty labels, prune empty labels. ... The semantics of honor_labels are that if a target exposes and empty label it will override the target labels. This PR fixes that by once again distinguishing between empty labels and missing labels in this one use case. Beyond that empty labels should be pruned and not added to storage, which this also fixes. Fixes #3841	7 years ago

Julius Volz	5da0fd91db	Add label matcher tests	7 years ago
Julius Volz	33c1171b9c	Don't add anchoring to exported `Value` matcher field ... Instead, just make the anchoring part of the internal regex. This helps because some users will want to read back the `Value` field and expect it to be the same as the input value (e.g. some tests in Cortex), or use the value in another context which is already expected to add its own anchoring, leading to superfluous double anchoring (such as when we translate matchers into remote read request matchers).	7 years ago
