promtool: fix check healthy/ready failing with a trailing slash in the URL#18854

CheckServerStatus built the request URL by concatenating the
user-provided URL with the endpoint path:
serverURL.String() + checkEndpoint
When the URL ends with a slash (e.g. "http://localhost:9090/"), this
produces a doubled slash like "http://localhost:9090//-/healthy". The
Prometheus router registers "/-/healthy" and "/-/ready" exactly and
does not collapse repeated slashes, so the request 404s and
"promtool check healthy" / "promtool check ready" fail.
Use url.JoinPath to append the endpoint, which normalises the slash and
also handles a configured route prefix correctly. JoinPath returns a new
URL, so the original is left untouched for the error message.

##### [\`v3.13.0\`](https://github.com/prometheus/prometheus/releases/tag/v3.13.0) This is a Long Term Support [LTS](https://prometheus.io/docs/introduction/release-cycle/) release. - \[SECURITY] UI: Bump `sanitize-html` to fix a cross-site scripting vulnerability (CVE-2026-44990). [#18697](prometheus/prometheus#18697) - \[CHANGE] UI: Third-party npm dependency licenses are now embedded in the Prometheus binary and served at `/assets/third-party-licenses.txt`, replacing the `npm_licenses.tar.bz2` archive previously shipped in release tarballs and container images. [#18997](prometheus/prometheus#18997) - \[CHANGE] API: Use SHA-256 instead of SHA-1 to generate rule group pagination tokens. [#18927](prometheus/prometheus#18927) - \[CHANGE] HTTP clients: Credentials (Authorization header, basic auth, bearer token, OAuth2, configured headers) are no longer forwarded when following a redirect to a different host; affects scraping, remote read/write, alerting, and service discovery. Via prometheus/common v0.69.0 (CVE-2025-4673 CVE-2023-45289). [#18949](prometheus/prometheus#18949) - \[CHANGE] promtool: Relative file paths in the file passed to `--http.config.file` are now resolved relative to that config file's directory instead of its parent directory. Via prometheus/common v0.69.0. [#18949](prometheus/prometheus#18949) - \[CHANGE] PromQL: Rename the `min()` and `max()` duration-expression functions (experimental feature flag `experimental-duration-expr`) to `min_of()` and `max_of()` to avoid confusion with the `min` and `max` aggregate operators. [#18687](prometheus/prometheus#18687) - \[FEATURE] API: Add experimental search endpoints to search metric names, label names, and label values. [#18573](prometheus/prometheus#18573) - \[FEATURE] Discovery/AWS: Add ability to filter RDS instances. [#18859](prometheus/prometheus#18859) - \[FEATURE] PromQL: Add `min_of(a, b)` and `max_of(a, b)` scalar experimental functions, returning the smaller or larger of two scalar values. [#18687](prometheus/prometheus#18687) - \[FEATURE] PromQL: Add support for smoothed/anchored rate with native histograms. [#18564](prometheus/prometheus#18564) - \[FEATURE] PromQL: Expose per-query `samplesRead` (and `samplesReadPerStep` with `stats=all` and the `promql-per-step-stats` feature flag) in the query stats response, and add the `prometheus_engine_query_samples_read_total` engine counter. `samplesRead` reflects storage I/O distinct from `totalQueryableSamples`, which counts samples loaded into the evaluator (and so over-counts when a sample is reused across multiple range-vector windows). [#18081](prometheus/prometheus#18081) - \[FEATURE] Scrape: Add `__convert_classic_histograms_to_nhcb__` internal label to allow per-target override of `convert_classic_histograms_to_nhcb` scrape configuration via relabeling. [#18840](prometheus/prometheus#18840) - \[FEATURE] TSDB: Add `storage.tsdb.chunk_encoding.floats` configuration field to select float chunk encoding (`xor` or `xor2`) at runtime, independently of the `--enable-feature=xor2-encoding` flag. [#18769](prometheus/prometheus#18769) - \[FEATURE] remote\_write: Add Certificate support for ingesting data into an Azure Monitor Workspace. [#18217](prometheus/prometheus#18217) - \[FEATURE] Scrape: Add `__always_scrape_classic_histograms__` and `__scrape_native_histograms__` internal labels to allow per-target override of the `always_scrape_classic_histograms` and `scrape_native_histograms` scrape configuration via relabeling. [#18929](prometheus/prometheus#18929) - \[ENHANCEMENT] Release: Container images are now also published to the GitHub Container Registry (ghcr.io). [#18791](prometheus/prometheus#18791) - \[ENHANCEMENT] PromQL: Prettify `fill_left(x) fill_right(x)` as `fill(x)` when both fill values are equal. [#18851](prometheus/prometheus#18851) - \[ENHANCEMENT] UI: Improve autocompletion after closing a function bracket. [#18894](prometheus/prometheus#18894) - \[PERF] Labels: Add case-insensitive prefix matching to speed up evaluation of long case-insensitive regular expressions (up to \~2x faster). [#18540](prometheus/prometheus#18540) - \[PERF] TSDB: Reduce per-sample overhead in chunk population, speeding up affected queries by \~12-15% in benchmarks. [#18699](prometheus/prometheus#18699) - \[PERF] TSDB: Eliminate unnecessary heap allocations in the V2 histogram WAL decoder, reducing allocations by up to 50% and memory by up to 10% for deployments using native histograms with created-timestamp storage enabled (`--enable-feature=created-timestamp-zero-ingestion`). [#18813](prometheus/prometheus#18813) - \[BUGFIX] Discovery/AWS: Fix failure when processing an AWS RDS cluster without instances. [#18845](prometheus/prometheus#18845) - \[BUGFIX] Fix race condition in initTime that could cause ErrOutOfBounds. [#18629](prometheus/prometheus#18629) - \[BUGFIX] PromQL: A range query whose `end` was not aligned to `step` caused subqueries inside it to evaluate past the parent's last actual step, inflating `peakSamples` in the query stats and against the `query.max-samples` limit, and wasting storage I/O reading samples that were never used in the result. [#18081](prometheus/prometheus#18081) - \[BUGFIX] PromQL: A range query containing an at-modifier-unsafe function over a range-vector with an `@` modifier (e.g. `predict_linear(metric[60s] @ T, X)`) silently under-counted `totalQueryableSamples` for steps after step 0. [#18081](prometheus/prometheus#18081) - \[BUGFIX] PromQL: Fix `fill_left`/`fill_right` producing missing samples in range queries when using `group_left`/`group_right`. [#18850](prometheus/prometheus#18850) - \[BUGFIX] PromQL: Fix for resets() and changes() in anchored range extenders with histograms. [#18906](prometheus/prometheus#18906) - \[BUGFIX] PromQL: Fix panic on `1[5m] smoothed` and similar expressions when extended range selectors are enabled. [#18764](prometheus/prometheus#18764) - \[BUGFIX] PromQL: Fix panic when a `smoothed` instant vector selector produces no samples for a series. [#18943](prometheus/prometheus#18943) - \[BUGFIX] PromQL: Fix panic when using a parenthesised plain number as an offset (e.g. `foo offset -(5)`). [#18768](prometheus/prometheus#18768) - \[BUGFIX] promtool: Fix panic when parsing exposition text containing empty braces `{}`. Via prometheus/common v0.69.0. [#18949](prometheus/prometheus#18949) - \[BUGFIX] Promtool: Fix `check healthy` and `check ready` when `--url` ends with a trailing slash. [#18854](prometheus/prometheus#18854) - \[BUGFIX] Rules: Close PromQL query after each rule evaluation to ensure resources are released. [#18733](prometheus/prometheus#18733) - \[BUGFIX] Scaleway SD: Resolve VPC/IPAM-only instances that have no legacy `private_ip` or `public_ip` field, but do have private NICs attached. [#18772](prometheus/prometheus#18772) - \[BUGFIX] TSDB: Do not leak head series when an integer histogram append is rejected (e.g. out-of-order). [#18838](prometheus/prometheus#18838) - \[BUGFIX] UI: Escape label values offered by PromQL autocomplete. [#18658](prometheus/prometheus#18658) - \[BUGFIX] TSDB: Fix chunk snapshot encoding for EncXOR2 chunks, preventing corruption on TSDB restart when EncXOR2-encoded series were present.

[#18949](prometheus/prometheus#18949) - \[CHANGE] PromQL: Rename the `min()` and `max()` duration-expression functions (experimental feature flag `experimental-duration-expr`) to `min_of()` and `max_of()` to avoid confusion with the `min` and `max` aggregate operators. [#18687](prometheus/prometheus#18687) - \[FEATURE] API: Add experimental search endpoints to search metric names, label names, and label values. [#18573](prometheus/prometheus#18573) - \[FEATURE] Discovery/AWS: Add ability to filter RDS instances. [#18859](prometheus/prometheus#18859) - \[FEATURE] PromQL: Add `min_of(a, b)` and `max_of(a, b)` scalar experimental functions, returning the smaller or larger of two scalar values. [#18687](prometheus/prometheus#18687) - \[FEATURE] PromQL: Add support for smoothed/anchored rate with native histograms. [#18564](prometheus/prometheus#18564) - \[FEATURE] PromQL: Expose per-query `samplesRead` (and `samplesReadPerStep` with `stats=all` and the `promql-per-step-stats` feature flag) in the query stats response, and add the `prometheus_engine_query_samples_read_total` engine counter. `samplesRead` reflects storage I/O distinct from `totalQueryableSamples`, which counts samples loaded into the evaluator (and so over-counts when a sample is reused across multiple range-vector windows). [#18081](prometheus/prometheus#18081) - \[FEATURE] Scrape: Add `__convert_classic_histograms_to_nhcb__` internal label to allow per-target override of `convert_classic_histograms_to_nhcb` scrape configuration via relabeling. [#18840](prometheus/prometheus#18840) - \[FEATURE] TSDB: Add `storage.tsdb.chunk_encoding.floats` configuration field to select float chunk encoding (`xor` or `xor2`) at runtime, independently of the `--enable-feature=xor2-encoding` flag. [#18769](prometheus/prometheus#18769) - \[FEATURE] remote\_write: Add Certificate support for ingesting data into an Azure Monitor Workspace. [#18217](prometheus/prometheus#18217) - \[FEATURE] Scrape: Add `__always_scrape_classic_histograms__` and `__scrape_native_histograms__` internal labels to allow per-target override of the `always_scrape_classic_histograms` and `scrape_native_histograms` scrape configuration via relabeling. [#18929](prometheus/prometheus#18929) - \[ENHANCEMENT] Release: Container images are now also published to the GitHub Container Registry (ghcr.io). [#18791](prometheus/prometheus#18791) - \[ENHANCEMENT] PromQL: Prettify `fill_left(x) fill_right(x)` as `fill(x)` when both fill values are equal. [#18851](prometheus/prometheus#18851) - \[ENHANCEMENT] UI: Improve autocompletion after closing a function bracket. [#18894](prometheus/prometheus#18894) - \[PERF] Labels: Add case-insensitive prefix matching to speed up evaluation of long case-insensitive regular expressions (up to \~2x faster). [#18540](prometheus/prometheus#18540) - \[PERF] TSDB: Reduce per-sample overhead in chunk population, speeding up affected queries by \~12-15% in benchmarks. [#18699](prometheus/prometheus#18699) - \[PERF] TSDB: Eliminate unnecessary heap allocations in the V2 histogram WAL decoder, reducing allocations by up to 50% and memory by up to 10% for deployments using native histograms with created-timestamp storage enabled (`--enable-feature=created-timestamp-zero-ingestion`). [#18813](prometheus/prometheus#18813) - \[BUGFIX] Discovery/AWS: Fix failure when processing an AWS RDS cluster without instances. [#18845](prometheus/prometheus#18845) - \[BUGFIX] Fix race condition in initTime that could cause ErrOutOfBounds. [#18629](prometheus/prometheus#18629) - \[BUGFIX] PromQL: A range query whose `end` was not aligned to `step` caused subqueries inside it to evaluate past the parent's last actual step, inflating `peakSamples` in the query stats and against the `query.max-samples` limit, and wasting storage I/O reading samples that were never used in the result. [#18081](prometheus/prometheus#18081) - \[BUGFIX] PromQL: A range query containing an at-modifier-unsafe function over a range-vector with an `@` modifier (e.g. `predict_linear(metric[60s] @ T, X)`) silently under-counted `totalQueryableSamples` for steps after step 0. [#18081](prometheus/prometheus#18081) - \[BUGFIX] PromQL: Fix `fill_left`/`fill_right` producing missing samples in range queries when using `group_left`/`group_right`. [#18850](prometheus/prometheus#18850) - \[BUGFIX] PromQL: Fix for resets() and changes() in anchored range extenders with histograms. [#18906](prometheus/prometheus#18906) - \[BUGFIX] PromQL: Fix panic on `1[5m] smoothed` and similar expressions when extended range selectors are enabled. [#18764](prometheus/prometheus#18764) - \[BUGFIX] PromQL: Fix panic when a `smoothed` instant vector selector produces no samples for a series. [#18943](prometheus/prometheus#18943) - \[BUGFIX] PromQL: Fix panic when using a parenthesised plain number as an offset (e.g. `foo offset -(5)`). [#18768](prometheus/prometheus#18768) - \[BUGFIX] promtool: Fix panic when parsing exposition text containing empty braces `{}`. Via prometheus/common v0.69.0. [#18949](prometheus/prometheus#18949) - \[BUGFIX] Promtool: Fix `check healthy` and `check ready` when `--url` ends with a trailing slash. [#18854](prometheus/prometheus#18854) - \[BUGFIX] Rules: Close PromQL query after each rule evaluation to ensure resources are released. [#18733](prometheus/prometheus#18733) - \[BUGFIX] Scaleway SD: Resolve VPC/IPAM-only instances that have no legacy `private_ip` or `public_ip` field, but do have private NICs attached. [#18772](prometheus/prometheus#18772) - \[BUGFIX] TSDB: Do not leak head series when an integer histogram append is rejected (e.g. out-of-order). [#18838](prometheus/prometheus#18838) - \[BUGFIX] UI: Escape label values offered by PromQL autocomplete. [#18658](prometheus/prometheus#18658) - \[BUGFIX] TSDB: Fix chunk snapshot encoding for EncXOR2 chunks, preventing corruption on TSDB restart when EncXOR2-encoded series were present. [#18739](prometheus/prometheus#18739) - \[BUGFIX] TSDB: Store a millisecond timestamp (not a WAL segment number) in walExpiries when a series is evicted via CompactStaleHead/CompactSelectedSeries, so the series's label record is correctly retained in the next WAL checkpoint and replays cleanly. [#18847](prometheus/prometheus#18847) - \[BUGFIX] TSDB: Prevent loss of samples at the chunk-range boundary when CompactSelectedSeries (and CompactStaleHead) evict the series — the per-slice compaction loop now runs one more iteration so the boundary timestamp is captured in a block before the in-memory copy is removed.

promtool check healthyandpromtool check readybuild the request URL by concatenating the server URL with the endpoint path:If the
--urlvalue ends with a slash (e.g.--url=http://localhost:9090/), this produces a doubled slash:http://localhost:9090//-/healthy. The router registers/-/healthyand/-/readyverbatim and does not collapse repeated slashes, so the request 404s and the command reportscheck failed: ... status=404even though the server is healthy. A trailing slash is easy to end up with in scripts and container HEALTHCHECKs.Fix is to append the endpoint with
url.JoinPathinstead of string concatenation. It normalises the slash and also keeps working when the server is served under a route prefix (e.g.http://host:9090/prometheus/->/prometheus/-/healthy).JoinPathreturns a new URL, so the original is untouched and the error message at the bottom of the function still prints the URL the user passed.Added
TestCheckServerStatuscovering both the plain and trailing-slash forms; it asserts the requested path is/-/healthyin both cases. The test fails before the change (//-/healthy) and passes after.
