Martin Valiente Ainz	af16f35ad6	PromQL: Refactor parser to use instance configuration instead of global flags Parser configuration is now per-engine/API/loader and no longer uses package-level flags, so behavior is consistent and tests don't rely on save/restore of global variables.

Julien	75f94903b3	Add OpenAPI 3.2 specification generation for Prometheus HTTP API (#17825 ) * Add OpenAPI 3.2 specification generation for Prometheus HTTP API This commit introduces an OpenAPI specification for the Prometheus API. After testing multiple code-generation servers with built-in APIs, this implementation uses an independent spec file outside of the critical path. This spec file is tested with a framework present in this pull request. The specification helps clients know which parameters they can use and is served at /api/v1/openapi.yaml. The spec file will evolve with the Prometheus API and has the same version number. Downstream projects can tune the APIs presented in the spec file with configuration options using the IncludePaths setting for path filtering. In the future, there is room to generate a server from this spec file (e.g. with interfaces), but this is out of scope for this pull request. Architecture: - Core OpenAPI infrastructure (openapi.go): Dynamic spec building, caching, and thread-safe spec generation - Schema definitions (openapi_schemas.go): Complete type definitions for all API request and response types - Path specifications (openapi_paths.go): Endpoint definitions with parameters, request bodies, and response schemas - Examples (openapi_examples.go): Realistic request/response examples - Helper functions (openapi_helpers.go): Reusable builders for common OpenAPI structures Testing: - Comprehensive test suite with golden file validation - Test helpers package for API testing infrastructure - OpenAPI compliance validation utilities The golden file captures the complete specification for snapshot testing. Update with: go test -run TestOpenAPIGolden -update-openapi-spec REVIEWERS: The most important thing to check would be the OpenAPI golden file (web/api/v1/testdata/openapi_golden.yaml). Test scenarios are important as they test the actual OpenAPI spec validity.

Julius Volz	8b1bd7d6c3	ui: Allow viewing detailed relabeling steps for each discovered target This adds: * A `ScrapePoolConfig()` method to the scrape manager that allows getting the scrape config for a given pool. * An API endpoint at `/api/v1/targets/relabel_steps` that takes a pool name and a label set of a target and returns a detailed list of applied relabeling rules and their output for each step. * A "show relabeling" link/button for each target on the discovery page that shows the detailed flow of all relabeling rules (based on the API response) for that target. Note that this changes the JSON encoding of the relabeling rule config struct to output the original snake_case (instead of camelCase) field names, and before merging, we need to be sure that's ok :) See my comment about that at https://github.com/prometheus/prometheus/pull/15383#issuecomment-3405591487 Fixes https://github.com/prometheus/prometheus/issues/17283 Signed-off-by: Julius Volz <julius.volz@gmail.com>	5 months ago

beorn7	747c5ee2b1	Apply analyzer "modernize" to the whole codebase See https://pkg.go.dev/golang.org/x/tools/gopls/internal/analysis/modernize for details. This ran into a few issues (arguably bugs in the modernize tool), which I will fix in the next commit, so that we have transparency what was done automatically. Beyond those hiccups, I believe all the changes applied are legitimate. Even where there might be no tangible direct gain, I would argue it's still better to use the "modern" way to avoid micro discussions in tiny style PRs later.

sh0rez	5303e515af	remote/otlp: convert delta to cumulative (#15165 ) What Adds support for OTLP delta temporality to the OTLP endpoint. This is done by calling the deltatocumulative processor from the OpenTelemetry collector during OTLP conversion. Why Delta conversion is a naturally stateful process, which requires careful request routing when operated inside a collector. Prometheus is already stateful and doing the conversion in-server reduces the operational burden on the ingest architecture by only having one stateful component. How deltatocumulative is a OTel collector component that works as follows: * pmetric.Metrics come from a receiver or in this case from the HTTP client * It operates as an in-place update loop: * for each sample, if not delta, leave unmodified * if delta, do: * state += sample, where state is the in-memory sum of all previous samples * sample = state, sample value is now cumulative * this is supported for sums (counters), gauges, histograms (old histograms) and exponential histograms (native histograms) If a series receives no new samples for 5m, its state is removed from memory Performance Delta performance is a stateful operation and the OTel code is not highly optimized yet, e.g. it locks the entire processor for each request. Nonetheless, care has been taken to mitigate those effects: delta conversion is behind a feature flag. If disabled, no conversion code is ever invoked if enabled, conversion is not invoked if request not actually contains delta samples. This leads to no measureable performance difference between default-cumulative to convert-cumulative (only cumulative, feature on/off) Signed-off-by: sh0rez <me@shorez.de>	1 year ago
