schemathesis 4.21.0

Release 4.21.0

on Python PyPI

🚀 Added

• Chain GraphQL operations on non-id identifiers (fullPath, slug, ...) in stateful and fuzzing phases.

🏎️ Performance

• Much lower peak memory and faster validation for schemas with very large maxLength / maxItems.
• Cache failed validator builds to avoid recompiling invalid patterns from large maxLength / maxItems values.
• Update hypothesis-graphql to 0.13.0 that brings up to 180x performance improvements for deeply nested GraphQL schemas.
• Update harfile to 0.5.0 for slightly better performance.
• Lower memory usage in long stateful runs.
• Faster, lower-memory stateful state machine construction for large schemas.

🐛 Fixed

• Excessive re-runs in stateful testing against APIs with mutable state.
• Stateful testing restarting on a single transient transport failure (e.g. dropped connection).
• Semantic value substitution overwriting const / enum fields with invalid data.

🔧 Changed

• Mine additionalProperties: false from Pydantic extra_forbidden errors and the exception_detail validation envelope.
