2.1.0

2.1.0 - 2026-03-10

Summary

This update improves error reporting for import_from_callback and export_to_callback (used internally for the import_from_* and export_to_* variants) by introducing a custom exception pattern. When data transfer fails, the library now captures and wraps exceptions from the main execution thread, the HTTP thread, and SQL thread. This ensures that concurrent failures are no longer obscured by whichever exception was caught first. Instead, the recorded exceptions are given with their tracebacks, making it easier to identify what went wrong.

Refactoring

• #303: Updated to exasol-toolbox 5.0.0
• #307: Updated to exasol-toolbox 5.1.1 and re-locked poetry.lock
• #309: Re-locked poetry.lock to resolve CVE-2026-26007, which affected cryptography versions <= 46.0.4
• #311: Updated to exasol-toolbox 6.0.0
• #317: Added check to export_to_callback and import_from_callback to ensure that the provided callback is Callable; if not, an exception is raised.
• #319: Improved error handling in the multithreaded export_to_callback so that all recorded exceptions are passed in ExaExportError
• #313: Improved error handling in the multithreaded import_from_callback so that all recorded exceptions are passed in ExaImportError
• #279: Modified documentation for exception changes in export_to_callback and import_from_callback
