Julien	1c449737e1	util/strutil: add Jaro-Winkler similarity implementation (#18405) ... * util/strutil: add Jaro-Winkler similarity implementation This is part of the implementation of prometheus/proposals#74 Signed-off-by: Julien Pivotto <291750+roidelapluie@users.noreply.github.com> * util/strutil: optimise JaroWinkler with string-native ASCII path Replace the generic jaroWinkler[T byte|rune] with two specialised functions: jaroWinklerString (ASCII path) operates directly on the string values and avoids the []byte conversion that previously caused two heap allocations per call; jaroWinklerRunes (Unicode path) is unchanged in algorithm but split out from the generic. Both paths replace the repeated float64 divisions in the Jaro formula with precomputed reciprocals (invL1, invL2). Result: short ASCII strings drop from 2 allocs/op to 0 allocs/op; long ASCII drops from 4 allocs/op to 2 allocs/op (bool match arrays only). Signed-off-by: Julien Pivotto <291750+roidelapluie@users.noreply.github.com> * util/strutil: replace JaroWinkler with JaroWinklerMatcher Remove the free JaroWinkler function and replace it with a JaroWinklerMatcher struct. NewJaroWinklerMatcher pre-computes the ASCII check and rune conversion for the search term once; Score then runs the comparison against each candidate without repeating that work. This is the expected usage pattern in Prometheus: one fixed term scored against many label names or values.

Ali	48f4a41e38	util/runtime: skip TestFsType on unknown filesystems instead of accepting hex format ... Rather than widening the assertion to accept raw hex codes, skip the strict _MAGIC format check with t.Skipf when the filesystem is not in the known map. The test still exercises the error paths and will run fully on standard Linux/macOS filesystems. Fixes prometheus/prometheus#18471 Signed-off-by: Ali <ali@kscope.ai>	2026-04-14 16:49:46 +05:00
Ali	366ee531bb	util/runtime: let TestFsType tolerate filesystems absent from FsType map ... FsType() returns the known magic-name string when the filesystem is present in its internal map, and falls back to strconv.FormatInt(..., 16) otherwise. The test was asserting the *MAGIC regex only, so it failed whenever it happened to run on a filesystem not yet mapped — the downstream Arch Linux packager hit this with a btrfs subvolume. Extend the regex to accept either a magic-name or the numeric lowercase-hex fallback, keeping the test stable across OS upgrades and exotic filesystems.

Sasha	1dcdb07d30	promql: use Kahan summation for Native Histograms (#15687) ... As for float samples, Kahan summation is used for the `sum` and `avg` aggregation and for the respective `_over_time` functions. Kahan summation is not perfect. This commit also adds tests that even Kahan summation cannot reliably pass. These tests are commented out. Note that the behavior might be different on other hardware platforms. We have to keep an eye on test failing on other hardware platforms and adjust them accordingly. Signed-off-by: Aleksandr Smirnov <5targazer@mail.ru>	2026-02-08 00:52:22 +01:00
