* lib/promrelabel: fix relabeling if clause being applied to labels outside of current context Relabeling is applied to each metric row separately, but in order to lower amount of memory allocations it is reusing labels. Functions which are working on current metric row labels are supposed to use only current metric labels by using provided offset, but if clause matcher was using the whole labels set instead of local metrics. This leaded to invalid relabeling results such as one described here: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4806 Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> * docs/CHANGELOG.md: document the bugfix Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1998 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4806 --------- Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> Co-authored-by: Aliaksandr Valialkin <valyala@victoriametrics.com>
