Lyo.PackageMetadata.Postgres

EF Core persistence for Lyo.PackageMetadata.IPackageMetadataStore.

Problem it solves

Stack traces contain stripped namespaces / assembly-qualified tokens. Lyo.PackageMetadata resolves which NuGet or Git package owns a prefix for diagnostics overlays. PostgresPackageMetadataStore implements the store against normalized tables (PackageStackPrefix rows ordered by NormalizedPrefix length) so resolution is O(sorted prefixes) in-process after each DB read. The bulk API loads all prefixes once per call when caching allows.

Storage model (conceptual)

  • PackageMetadataEntity holds catalog metadata (id, package name, version range, SPDX/license expression blobs). See EF configurations for the rest.
  • PackageStackPrefixEntity maps NormalizedPrefix to the owning package. Longest prefix wins.

Bulk resolution (TryGetManyForStrippedMethodPrefixesAsync)

  • Input: list of distinct stripped prefixes (typically one per decoded stack frame subtree).
  • Output: dictionary including one entry per input key, value null when nothing matches contract rules.
  • Never silently drop requested keys. That invariant keeps Lyo.Diagnostic bulk decode paths deterministic.

Prefix catalog caching (PostgresPrefixCatalogCachingMode)

PostgresPackageMetadataOptions.PrefixCatalogCaching controls repeated DB chatter:

Mode Meaning
InvalidateOnRegisterManyOrClear Keep an immutable in-process snapshot. Reload when mutations bump the generation counter (ClearPrefixCatalogCache or RegisterManyAsync on the same instance).
Disabled Always hit Postgres. Wrap with an outer cache yourself if importing huge catalogs asynchronously.

ClearPrefixCatalogCache() is a no-op on the cache when caching is disabled. It only bumps the generation.

Cross-process writes do not invalidate. Disable the snapshot or bust the cache after CLI imports.

DI registration (Extensions)

  • AddPackageMetadataDbContextFactory (and FromConfiguration). Binds PostgresPackageMetadataOptions, registers the PackageMetadataDbContext factory, attaches AddPostgresMigrations bootstrap.
  • AddPostgresPackageMetadataStore. Factory plus IPackageMetadataStore as PostgresPackageMetadataStore singleton resolving options and IDbContextFactory.

Migrations & schema

Migrations ship under Migrations/. Schema and table names follow PostgresPackageMetadataOptions.Schema. Inspect the snapshot for authoritative DDL.
