- Add workflow_dispatch inputs for baseline_version and version_matrix - Create prepare-matrix job to dynamically build version array from inputs - Support comma-separated version lists without code changes - Update README with configuration examples and GitHub CLI commands - Maintain backward compatibility with default version matrix
… restore errors The test project's restore process looks for a local packages source at artifacts/local-packages. When this directory doesn't exist in CI, NuGet fails with NU1301 errors. Creating the directory (even if empty) prevents these errors while still allowing local development workflows.
- Remove baseline-only quick check mode; always run full matrix
- Add build-current-package job that builds current source as NuGet with unique version (1.0.0-pr{n}-{run} or 1.0.0-ci-{run})
- Update prepare-matrix to inject current package version into test matrix
- Add conditional local NuGet source setup when testing current version
- Update documentation to reflect simplified workflow
Directory.Build.props includes artifacts/local-packages in RestoreSources, so the folder must exist before running dotnet restore/pack operations.
All jobs need the artifacts/local-packages folder to exist because Directory.Build.props includes it in RestoreSources. When testing the current package version, we copy the built package into this folder so it can be resolved during dotnet restore.
The test framework (CrossVersionEncryptionTests) automatically generates all version pairs from the versions array in testconfig.json. The CI workflow now: 1. Builds current source as a NuGet package with unique version 2. Updates testconfig.json with versions to test (default: preview07,current) 3. Runs tests which internally test all pairs: - preview07 → preview07 - preview07 → current - current → preview07 - current → current This is simpler than managing pairs at the CI level and matches how the test framework is designed to work.
Remove '1.0.0-preview08-next' which doesn't exist as a published package. The CI workflow will dynamically update this file to add the current source version before running tests.
Previously, VersionLoader only checked artifacts/local-packages for versions containing 'current' in the name. Now it always checks the local packages folder first for ANY version before falling back to the global NuGet cache. This enables the CI workflow to build packages with versions like '1.0.0-preview08-pr4-3' and have them correctly resolved during tests.
Resolved Git conflict markers that were causing YAML syntax error.

…ersions - Expose AssemblyPath in VersionLoader for file-level inspection - Add AssemblyBinaryValidation test that verifies: * SHA256 file hashes are unique (proves different binaries) * Assembly paths are different (proves separate loading) * File sizes (additional validation) * Assembly version attributes (AssemblyVersion, FileVersion, InformationalVersion) * Strong name/public key token consistency - Detailed output shows full comparison matrix for debugging
- Replace hardcoded individual jobs with matrix strategy - Matrix spawns parallel jobs for each version in VersionsToTest - PR/CI builds: test only against BaselineVersion (preview07) - Scheduled/Manual runs: test against full matrix (preview07, 06, 05, 04) - Easy to add new versions by updating VersionsToTest variable - Groundwork for future version additions
- Changed from runtime variables to compile-time parameters - Matrix now properly expands with parameters.VersionsToTest - Each version spawns as separate parallel job - Fixed replace() to handle both dots and dashes in version strings - Updated documentation comments to reflect parameter-based approach
- Consolidated QuickCheck and FullMatrix stages into single CompatibilityMatrix stage - PR builds: Matrix spawns 2 jobs (preview07, preview06) for fast feedback - Non-PR builds: Matrix spawns 4 jobs (preview07, 06, 05, 04) for full coverage - Matrix dimension names now visible in job list (e.g., '1_0_0_preview07') - Simplified stage dependencies (ApiCompatibilityCheck -> CompatibilityMatrix -> Report)
- Replaced single job testing all pairs with matrix spawning separate jobs - Matrix creates 2 jobs per run: current→preview07 and preview07→current - Job names now clearly show version pairs: 'Test X ⟷ Y' - Each matrix job tests specific encrypt/decrypt version combination - Separate artifacts per version pair for easier debugging - fail-fast: false ensures all combinations run even if one fails - Groundwork for expanding matrix to more version combinations
- Removed redundant directional testing (A→B and B→A) - Matrix now spawns 1 job per version pair instead of 2 - Tests are bidirectional by nature (both encrypt/decrypt directions covered) - Job name: 'Test current_vs_preview07' showing both versions tested - Reduces pipeline execution time by 50% - Easier to add more version pairs without exponential job growth
- Build step now supports matrix of source repositories and branches - Can test against PRs from forks by specifying repo/ref in build_sources - Default: builds from current repository and branch - Manual override via workflow_dispatch build_sources input (JSON array) - Each build source tested against all specified versions (cross product) - Job naming shows source name and test version clearly - Enables testing compatibility between different development branches

- Added debug output to show event name and inputs - Fixed empty string check for build_sources input - Now correctly expands matrix for manual/scheduled runs - Manual runs without custom input will test all 6 sources (current + 5 PRs)
- Removed conditional logic that limited PR builds to single source - Now ALWAYS tests all 6 sources (current + 5 PRs) on every run - Applies to: pull_request, push, schedule, and workflow_dispatch - Only exception: custom build_sources via workflow_dispatch input - Provides comprehensive compatibility validation on every trigger
- Changed from 'include' to direct 'build_source' matrix dimension - Fixed checkout to use matrix.build_source.repository/ref - Fixed debug output to use matrix.build_source.* properties - This resolves artifact upload failures and checkout errors
- Changed from multi-line to single-line JSON array - Removes whitespace and newlines that caused 'Invalid format' error - Ensures proper parsing by GitHub Actions output processor
- Add continue-on-error to build step to handle API incompatibilities - Only upload artifacts for successfully built packages - Skip test execution for sources that failed to build - Add clear messaging when builds/tests are skipped - Update test summary to show skipped vs tested sources This allows testing compatible PRs while gracefully handling ones with breaking API changes (e.g., PR Azure#5403, Azure#5385).
- Remove continue-on-error from build step (build failures now fail the job) - Add if: always() to compatibility-tests job (runs even if some builds fail) - Test jobs skip gracefully when corresponding build job failed - Failed builds will show as red X, successful builds as green checkmark - Only successfully built packages will be tested

…ontainer doesn't exist (Direct mode) (Azure#5500) ## Description When operations fail with 404, it's ambiguous whether the item doesn't exist or the parent container/database doesn't exist. This PR fixes the SDK to properly set substatus code 1003 (OwnerResourceNotFound) when collection resolution fails during item operations, enabling developers to distinguish between these two fundamentally different error conditions. ### Changes -**SDK Fix**: Modified `ClientCollectionCache.ResolveCollectionWithSessionContainerCleanupAsync` to set substatus 1003 when collection resolution fails with 404 for non-container operations - Item/document operations now correctly get 404/1003 when container doesn't exist (Direct mode) - Container metadata operations continue to get 404/0 when container doesn't exist (the container itself is the missing resource) - Query and stored procedure operations get 404/1003 when container doesn't exist - **Emulator Tests**: Added parameterized tests validating substatus code behavior in both TCP (Direct) and Gateway connection modes - 404/0 → item not found in existing container - 404/1003 → container or database doesn't exist (Direct mode) - Tests run with `[DataRow]` attributes for both connection modes - Test names clarified with `_StreamingAPI` and `_TypedAPI` suffixes to indicate which API type is being tested - `ValidateSubStatusCodeForItemNotFoundVsContainerNotFound_StreamingAPI` tests streaming APIs (ReadItemStreamAsync) - `ValidateCosmosExceptionSubStatusCodeForNotFound_TypedAPI` tests typed/non-streaming APIs (ReadItemAsync) - `ValidateContainerMetadataRequestsHaveSubstatus0` validates that container operations correctly return substatus 0 - **Unit Tests**: Added tests for CosmosException and ResponseMessage substatus code handling - **Documentation**: Added examples in `Exceptions.md` showing how to distinguish these cases ### Direct Mode vs Gateway Mode __Direct Mode (TCP)__: - Fully supports substatus code 1003 for container-not-found scenarios - Can distinguish between item-not-found (404/0) and container-not-found (404/1003) __Gateway Mode__: - Known limitation: Cannot always distinguish these scenarios due to Gateway architecture - Returns 404/0 for both item-not-found and container-not-found - Database-not-found scenarios still return 404/1003 in both modes ### Usage Check `SubStatusCode` to differentiate 404 scenarios: ```csharp try { var response = await container.ReadItemAsync(id, partitionKey); } catch (CosmosException ex) when (ex.StatusCode == HttpStatusCode.NotFound) { if (ex.SubStatusCode == 1003) { // Container/database doesn't exist - may need to create it // (Direct mode only for container-not-found) } else { // Item doesn't exist - normal case } } ``` Same pattern works with `ResponseMessage.Headers.SubStatusCode` for stream APIs. ## Type of change - [x] Bug fix (non-breaking change which fixes an issue) ## Closing issues Resolves Azure#227 Fixes Azure#229 <!-- START COPILOT CODING AGENT TIPS --> --- 💬 We'd love your input!

# Pull Request Template
## Description
This pull request introduces a new semantic reranking feature to the
Azure Cosmos DB .NET SDK, enabling users to rerank documents using an
inference service that leverages Azure Active Directory (AAD)
authentication. The main changes include the addition of the
`InferenceService` class, new API surface for semantic reranking, and
appropriate integration into the SDK's authorization and client context
infrastructure. Notably, this functionality is only available when using
AAD authentication.
**Semantic Reranking Feature Integration:**
* Added the `InferenceService` class, which handles communication with
the Cosmos DB Inference Service for semantic reranking, including HTTP
client configuration, payload construction, and response handling. This
service enforces AAD authentication and manages its own authorization
and disposal.
* Introduced a new public (under `PREVIEW`) or internal API
`SemanticRerankAsync` to the `Container` class, allowing users to rerank
a list of documents based on a context/query string. This is implemented
in `ContainerInlineCore` and routed through the client context.

* To use this feature, the environment variable
"AZURE_COSMOS_SEMANTIC_RERANKER_INFERENCE_ENDPOINT", must be set with
the inference endpoint from the service.
* Additionally, the environment variable
"AZURE_COSMOS_SEMANTIC_RERANKER_INFERENCE_SERVICE_MAX_CONNECTION_LIMIT",
can be set to change the inference client's max connection limit.
**Authorization and Token Handling Updates:**
* Extended the `AuthorizationTokenProvider` abstraction and its
implementations to support a new method,
`AddInferenceAuthorizationHeaderAsync`, which is only valid for
AAD-based token providers. Non-AAD providers throw a
`NotImplementedException` for this method.

**Client Context and Resource Management:**
* Updated `ClientContextCore` and `CosmosClientContext` to manage the
lifecycle of the `InferenceService`, including creation, caching, and
disposal. Added methods for invoking semantic reranking and for
retrieving or creating the inference service instance.
