Move conversion context to connector by NinoFloris · Pull Request #6587 · npgsql/npgsql

test/Npgsql.Tests/WriteStateTests.cs Updates parameter binding calls to pass an explicit conversion context in tests. test/Npgsql.Benchmarks/WriteParameter.cs Uses connector conversion context for benchmark parameter binding. src/Npgsql/Replication/PgOutput/ReplicationValue.cs Uses connector conversion context when resolving field types and conversion contexts. src/Npgsql/NpgsqlParameterCollection.cs Threads conversion context into validation-time parameter binding. src/Npgsql/NpgsqlParameter`.cs Passes conversion context into typed parameter binding. src/Npgsql/NpgsqlParameter.cs Updates Bind/typed binding hooks to accept conversion context and flow it into concrete binding. src/Npgsql/NpgsqlNestedDataReader.cs Passes connector conversion context into field binding for nested reads. src/Npgsql/NpgsqlDataSource.cs Stops constructing serializer options with per-connector encoding/timezone; options become context-agnostic. src/Npgsql/NpgsqlDataReader.cs Threads connector conversion context into row description conversion-context resolution. src/Npgsql/NpgsqlCommand.cs Passes connector conversion context into parameter processing. src/Npgsql/NpgsqlBinaryImporter.cs Passes connector conversion context into binary import parameter binding. src/Npgsql/NpgsqlBinaryExporter.cs Passes connector conversion context into binary export field binding. src/Npgsql/Internal/PgWriter.cs Captures conversion context per Init and uses cached encoder when available to reduce allocations. src/Npgsql/Internal/PgTypeInfo.cs Probes descriptors with empty context, caches invariance flags, and re-resolves requirements when non-invariant. src/Npgsql/Internal/PgSerializerOptions.cs Removes TimeZone provider and shared ConversionContext from serializer options. src/Npgsql/Internal/PgReader.cs Sources conversion context from connector (or buffer fallback when connector-less). src/Npgsql/Internal/PgConverter.cs Extends PgConversionContext to carry encoder/timezone; documents invariance via ConverterDescriptor. src/Npgsql/Internal/NpgsqlWriteBuffer.cs Sources encoding from connector dynamically and uses connector encoder; adds fallback conversion context for connector-less buffers. src/Npgsql/Internal/NpgsqlReadBuffer.cs Sources encoding from connector dynamically; adds fallback conversion context for connector-less buffers. src/Npgsql/Internal/NpgsqlConnector.FrontendMessages.cs Binds parameters using connector conversion context when writing Bind messages. src/Npgsql/Internal/NpgsqlConnector.cs Adds per-connector conversion context and encoder cache; rotates them on TimeZone/client_encoding ParameterStatus changes. src/Npgsql/Internal/Converters/RecordConverter.cs Binds fields using the runtime reader conversion context. src/Npgsql/Internal/Converters/CompositeConverter.cs Resolves composite field read requirements using runtime conversion context. src/Npgsql/Internal/Composites/Metadata/CompositeFieldInfo.cs Re-resolves requirements for non-invariant composite fields using runtime conversion context; adjusts fast-path assumptions. src/Npgsql/BackendMessages/RowDescriptionMessage.cs Threads conversion context into field binding/conversion-context resolution and field-type lookup. src/Npgsql.NodaTime/Internal/NodaTimeTypeInfoResolverFactory.cs Stops capturing time zone at mapping creation; defers to runtime context. src/Npgsql.NodaTime/Internal/LegacyConverters.cs Resolves session time zone at read-time from PgConversionContext and preserves the localtime error behavior.
