c7b2210ac3 tsdb: cache collected head chunks on ChunkReader for O(1) lookup (#18302)
tsdb: cache collected head chunks on ChunkReader for O(1) lookup

The query path calls s.chunk() once per chunk meta via
ChunkOrIterableWithCopy. Each call walks the head chunks linked list
from the head to the target position. For a series with N head chunks
iterated oldest-first, total work is O(N²).

Cache the collected []*memChunk slice on headChunkReader, keyed by
series ref, head pointer, and mmapped chunks length. Collected once
per series under lock; reused on subsequent chunk lookups for the same
series. The backing array is reused across series (zero alloc after
first use).

Series with 0 or 1 head chunks skip the cache entirely to avoid
per-series overhead that dominates for typical workloads where most
series have a single head chunk.

The cache is gated behind an enableCache flag, toggled via an optional
chunkCacheToggler interface only when hints.Step > 0 (range queries).
Instant queries only need one chunk per series, so the cache overhead
is not recouped.

Also replace O(N²) linked-list traversals in appendSeriesChunks with
O(N) collectHeadChunks + slice iteration, and thread reusable
headChunksBuf through the index reader paths to avoid per-series
allocations.

85dbc3cc76 promql: fix smoothSeries() @ modifier timestamp mismatch
smoothSeries() was stamping output points at offset-adjusted timestamps
instead of evaluator timestamps. When the @ modifier is used, this
causes gatherVector() to miss the points because it matches by exact
timestamp equality against evaluator step timestamps.

Fix by iterating over evaluator timestamps and deriving data timestamps
by subtracting the offset, so output points align with what
gatherVector() expects.

93ec767fed promql: fix smoothed rate returning zero for data only after range
For smoothed rate/increase, a result should only be returned
when there is data available to interpolate across the range. If the
range has a single data point only on one side, the result is
meaningless and should be empty.

The "data only before" case was already handled: if the last fetched
sample is at or before rangeStart, extendedRate returns nothing.

Add the symmetric guard for the "data only after" case: if the first
fetched sample is strictly after rangeEnd, return nothing as well.

This mirrors the behaviour described in prometheus/prometheus#18295,
where a smoothed rate that has no data before the range should not
return zero.

98809e40c6 tsdb: Skip clean series during periodic head chunk mmap (#18272)
tsdb: Skip clean series during periodic head chunk mmap

The periodic mmapHeadChunks cycle previously acquired a per-series
lock on every series, even though typically >99% have nothing to
mmap. This was identified as a CPU bottleneck in Grafana Mimir.

Add a headChunkCount field (sync/atomic.Uint32) to memSeries that
tracks the number of head chunks. It is incremented in
cutNewHeadChunk and the histogram new-chunk paths, and reset by
mmapChunks and truncateChunksBefore. mmapHeadChunks uses a lock-free
Load to skip series with fewer than 2 head chunks, avoiding the
per-series lock for clean series.

sync/atomic.Uint32 (4 bytes) is used instead of go.uber.org/atomic
(8 bytes) to fit in existing struct padding without growing
memSeries. Chunk counts are bounded by the 3-byte field in
HeadChunkRef, so cannot overflow uint32.

Also fix pre-existing comment inaccuracies in the touched code:
headChunks.next -> headChunks.prev, mmapHeadChunks() -> mmapChunks()
in the doc comment, and a grammar error.

1c449737e1 util/strutil: add Jaro-Winkler similarity implementation (#18405)
* util/strutil: add Jaro-Winkler similarity implementation

* 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).

* 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.

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.

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.

Fixes #18471

d946df2b66 Remove Gitpod config files and badge in README.md
Gitpod has rebranded to Ona a while ago and is now focusing on AI-agentic
coding, so at least the traditional links that opened the repo in a cloud-based
coding environment without login don't work anymore. So let's remove the files
and badge to get rid of old cruft.

318c913fe2 Add API endpoint for getting Prometheus' metrics about itself
This adds a /api/v1/status/self_metrics endpoint that allows the frontend to
fetch metrics about the server itself, making it easier to construct frontend
pages that show the current server state. This is needed because fetching
metrics from its own /metrics endpoint would be both hard to parse and also
require CORS permissions on that endpoint (for cases where the frontend
dashboard is not the same origin, at least).

fddbccf79b UI: Fix stored XSS via unescaped metric names and labels
Metric names, label names, and label values containing HTML/JavaScript were
inserted into `innerHTML` without escaping in several UI code paths, enabling
stored XSS attacks via crafted metrics. This mostly becomes exploitable in
Prometheus 3.x, since it defaults to allowing any UTF-8 characters in metric
and label names.

Apply `escapeHTML()` to all user-controlled values before innerHTML
insertion in:

* Mantine UI chart tooltip
* Old React UI chart tooltip
* Old React UI metrics explorer fuzzy search
* Old React UI heatmap tooltip

See https://github.com/prometheus/prometheus/security/advisories/GHSA-vffh-x6r8-xx99

4cc50803ff discovery/consul: fix catalog watch trigger and improve filter tests
When health_filter is set without explicit services, the catalog needs
to be watched to enumerate services. Add watchedFilter to the condition
that triggers catalog watching.

Improve the filter test suite:
- Replace defer with t.Cleanup for stub servers.
- Rewrite TestFilterOption to assert that the catalog receives the filter
  and the health endpoint does not.
- Rewrite TestHealthFilterOption to assert that health_filter is routed
  correctly to the health endpoint only.
- Add TestBothFiltersOption to verify both filters are routed to their
  respective endpoints when both are configured.

1e73d2fcde discovery/consul: add health_filter for Health API filtering
The filter field was documented as targeting the Catalog API but since
PR #17349 it was also passed to the Health API. This broke existing
configs using Catalog-only fields like ServiceTags, which the Health API
rejects (it uses Service.Tags instead).

Introduce a separate health_filter field that is passed exclusively to
the Health API, while filter remains catalog-only. Update the docs to
explain the two-phase discovery (Catalog for service listing, Health for
instances) and the field name differences between the two APIs.

Fixes #18479
