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. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Refactor engine labelset signature generation, just use labels.Labels instead of hashes. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Address review comments; function comments + store result of lhs.String+rhs.String as key. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Replace all signatureFunc usage with signatureFuncString. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Make optimizations to labels String function and generation of rhs+lhs as string in resultMetric. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Use separate string functions that don't use strconv just for engine maps. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Use a byte invalid separator instead of quoting and have a buffer attached to EvalNodeHelper instead of using a global pool in the labels package. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Address review comments. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Address more review comments, labels has a function that now builds a byte slice without turning it into a string. Signed-off-by: Callum Styan <callumstyan@gmail.com> * Use two different non-ascii hex codes as byte separators between labels and between sets of labels when building bytes of a Labels struct. Signed-off-by: Callum Styan <callumstyan@gmail.com> * We only need the 2nd byte invalid sep. at the beginning of a labels.Bytes Signed-off-by: Callum Styan <callumstyan@gmail.com>		5 years ago
