Jeremy Rickards	530c4bfcc9	docs: clarify that histogram_avg/count/sum/stddev/stdvar are native-histogram-only ... The docs for these functions previously described them as acting on "each histogram sample," which was ambiguous. Add "native" to clarify they only operate on native histogram samples, not classic histograms. This distinction was originally documented but lost when the experimental feature warnings were removed.

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.

matt-gp	9b6e244b83	AWS SD: ECS Bridge Mode ... Previously the AWS SD ECS Role only discovered instances that used `awsvpc` network mode, which attaches a dedicated Elastic Network Interface (ENI). This change adds in additional logic so that we discover instances that are using `host` and `bridge` networking modes, where the IP address is that of the EC2 instance that is hosting the container. Also this change exposes a number of additional labels that relate to the EC2 instance when the launch type is `EC2`. Signed-off-by: matt-gp <small_minority@hotmail.com>	2025-12-25 19:26:14 +00:00
