Revives the configuration-schema work from stale PR #14159.

  • Generate JSON Schemas for serving, disaggregated serving, and VisualGen YAML configs to support editor validation and completion.
  • Publish schemas with the docs and include snapshots in the repo, wheels, and release containers.
  • Add freshness checks and regeneration guidance.

Validation: 63 focused tests passed, plus editor, Sphinx, wheel-packaging, and container-path smoke checks. Full GPU build/CI not run.

Dev Engineer Review

The change generates schemas for serving, disaggregated serving, and VisualGen configuration. It adds freshness checks and publishes the snapshots through HTML documentation, wheels, and release images.

Generator adaptations can drift from runtime validation as configuration models change. The new tests cover schema generation, selected runtime parity, aliases, and packaging. The change also centralizes serving aliases and CLI mappings, adds strict internal-request-auth-key validation, and derives the router default from RouterConfig.type. No supplied test results establish execution success or a full GPU CI result.

QA Engineer Review

The changed tests cover schema structure and validation, runtime parity, configuration examples, documentation publication, stale snapshots, wheel packaging, and precompiled-artifact extraction. The schema test is explicitly listed in tests/integration/test_lists/test-db/l0_cpu.yml; the precompiled-artifact and packaging tests are included through the unittest/others and unittest/scripts entries in that list.

Coverage verdict: sufficient for the schema, publication, and packaging behaviors represented by the tests. No test execution results are available.

Per-File QA Perspective

  • .gitattributes: Marks schema JSON files as generated for Linguist. Verify the snapshots receive the intended classification.
  • AGENTS.md: Adds schema regeneration, inspection, and testing guidance. Verify the documented commands and version-bump guidance remain accurate.
  • docker/Dockerfile.multi: Adds a release-image symlink to the installed schema directory and checks for required schema files. Verify the package path and missing-file failure during image builds.
  • docs/source/_ext/trtllm_schema_assets.py: Copies schema snapshots to HTML output after successful HTML builds. Verify non-HTML and failed builds skip copying.
  • docs/source/commands/trtllm-serve/trtllm-serve.rst: Documents editor validation, schema locations, and regeneration. Verify the instructions match wheel and HTML publication behavior.
  • docs/source/conf.py: Enables the schema asset extension. Verify Sphinx loads it during documentation builds.
  • scripts/generate_trtllm_serve_schemas.py: Adds schema generation and stale-snapshot checks. Verify generated constraints and custom adaptations stay aligned with runtime validation.
  • setup.py: Requires schema snapshots and includes them as package data. It also updates precompiled-artifact extraction handling. Verify wheel contents and preservation of checkout-owned files.
  • tensorrt_llm/schemas/__init__.py: Adds package documentation for generated schemas. No behavior change is described.
  • tensorrt_llm/schemas/trtllm-serve-visual-gen-config.schema.json: Adds the VisualGen configuration schema. Verify representative valid and invalid inputs against runtime validation.
  • tests/integration/test_lists/test-db/l0_cpu.yml: Adds the schema test entry. The precompiled-artifact and packaging test files are also selected through existing unittest/others and unittest/scripts entries.
  • tests/unittest/llmapi/test_trtllm_serve_config_schemas.py: Covers schema fields, runtime parity, aliases, auth-key rules, router defaults, existing configurations, documentation publication, determinism, and stale snapshots. It is listed in the CPU test list.
  • tests/unittest/others/test_precompiled_link_mode.py: Adds parameterized coverage that extraction preserves schema files for wheel, copy, and link sources. It is selected through unittest/others in the CPU test list.
  • tests/unittest/scripts/test_serve_schema_packaging.py: Covers wheel inclusion of the three schemas and failure when a required schema is missing. It is selected through unittest/scripts in the CPU test list.
  • tensorrt_llm/commands/serve.py: Uses shared CLI configuration mappings and validates the internal request authentication key. Verify CLI-to-config values and invalid-key handling.
  • tensorrt_llm/llmapi/disagg_utils.py: Adds strict auth-key validation and derives the router default from RouterConfig.type. Verify extraction, inheritance, and invalid-input behavior.
  • tensorrt_llm/llmapi/llm_args.py: Centralizes aliases and CLI-to-nested-field mappings, and declares validator input types. Verify YAML precedence and schema/runtime consistency.
  • tensorrt_llm/usage/llm_args_golden_manifest.json: Changes capture-policy shapes for two CUDA graph fields. Verify telemetry capture still matches runtime values.

Walkthrough

This change adds generation and validation for serving, disaggregated-serving, and VisualGen YAML schemas. It also updates serving configuration handling, packages and publishes schema snapshots, and validates internal request auth keys.

Changes

Serving YAML schemas

Layer / File(s) Summary
Align serving configuration contracts
tensorrt_llm/llmapi/llm_args.py, tensorrt_llm/llmapi/disagg_utils.py, tensorrt_llm/commands/serve.py, tensorrt_llm/usage/llm_args_golden_manifest.json
Shared mappings and build_cli_config handle CLI values for nested configuration. Serving and disaggregated configuration use strict internal auth-key validation. The router default uses RouterConfig.type. The golden manifest updates the shape capture policy for two CUDA graph fields.
Generate and validate serving schemas
scripts/generate_trtllm_serve_schemas.py, tensorrt_llm/schemas/*, tests/unittest/llmapi/test_trtllm_serve_config_schemas.py, tests/integration/test_lists/test-db/l0_cpu.yml, AGENTS.md, .gitattributes
The generator produces schemas for three serving configuration types and can write snapshots or check for missing or stale files. CPU tests cover schema validation, runtime parity, YAML examples, and snapshot freshness. Contributor instructions describe schema maintenance, and Linguist marks schema JSON files as generated.
Package and publish schema snapshots
setup.py, docker/Dockerfile.multi, tests/unittest/scripts/test_serve_schema_packaging.py, tests/unittest/others/test_precompiled_link_mode.py, docs/source/_ext/trtllm_schema_assets.py, docs/source/conf.py, docs/source/commands/trtllm-serve/trtllm-serve.rst
Package checks require the three schema files, and wheel package data includes them. The release image links the installed schema directory into /app/tensorrt_llm/schemas. Tests check wheel contents and checkout-file preservation during precompiled extraction. The Sphinx extension publishes schemas after successful HTML builds, and the serving guide documents schema use and limits.

Review comments at @docs/source/_ext/trtllm_schema_assets.py:
- Around line 30-32: Update the schema-generation hook around write_schemas so
an ImportError falls back to copying committed JSON snapshots from
tensorrt_llm/schemas into the output directory when TRTLLM_DOCS_REQUIRE_IMPORT
is not set to "1"; re-raise the error when it is. Add a test for the ImportError
fallback using a run_path stub that raises ImportError.

Review comments at @scripts/generate_trtllm_serve_schemas.py:
- Around line 227-228: Update schema generation so committed snapshots omit
version-dependent `$id` and `title` values, keeping them stable across version
bumps; add versioned metadata only in the docs-publish path via `write_schemas`
and `docs/source/_ext/trtllm_schema_assets.py`.

Use common alias mappings in runtime construction, config precedence, and schema generation. Describe accepted inputs beside the existing Pydantic validators instead of patching their generated schemas.

Add drift regression tests and regenerate snapshots. Refresh two pre-existing telemetry manifest discrepancies; before/after model checks produce identical capture manifests.
