- Bumped up min boto and botocore version to 1.24 - - OCSP: terminate certificates chain traversal if a trusted certificate already reached - -- v3.14.1(April 21, 2025) - - Added support for Python 3.13. - - NOTE: Windows 64 support is still experimental and should not yet be used for production environments. - - Dropped support for Python 3.8. - - Added basic decimal floating-point type support. - - Added experimental authentication methods. - - Added support of GCS regional endpoints. - - Added support of GCS virtual urls. See more: https://cloud.google.com/storage/docs/request-endpoints#xml-api - - Added `client_fetch_threads` experimental parameter to better utilize threads for fetching query results. - - Added `check_arrow_conversion_error_on_every_column` connection property that can be set to `False` to restore previous behaviour in which driver will ignore errors until it occurs in the last column. This flag's purpose is to unblock workflows that may be impacted by the bugfix and will be removed in later releases. - - Lowered log levels from info to debug for some of the messages to make the output easier to follow. - - Allowed the connector to inherit a UUID4 generated upstream, provided in statement parameters (field: `requestId`), rather than automatically generate a UUID4 to use for the HTTP Request ID. - - Improved logging in urllib3, boto3, botocore - assured data masking even after migration to the external owned library in the future. - - Improved error message for client-side query cancellations due to timeouts. - - Improved security and robustness for the temporary credentials cache storage. - - Fixed a bug that caused driver to fail silently on `TO_DATE` arrow to python conversion when invalid date was followed by the correct one. - - Fixed expired S3 credentials update and increment retry when expired credentials are found. - - Deprecated `insecure_mode` connection property and replaced it with `disable_ocsp_checks` with the same behavior as the former property. - -- v3.14.0(March 03, 2025) - - Bumped pyOpenSSL dependency upper boundary from <25.0.0 to <26.0.0. - - Removed the workaround for a Python 2.7 bug. - - Added a <19.0.0 pin to pyarrow as a workaround to a bug affecting Azure Batch. - - Optimized distribution package lookup to speed up import. - - Fixed a bug where privatelink OCSP Cache url could not be determined if privatelink account name was specified in uppercase. - - Added support for iceberg tables to `write_pandas`. - - Fixed base64 encoded private key tests. - - Fixed a bug where file permission check happened on Windows. - - Added support for File types. - - Added `unsafe_file_write` connection parameter that restores the previous behaviour of saving files downloaded with GET with 644 permissions. - - Deprecated `insecure_mode` connection property and replaced it with `disable_ocsp_checks` with the same behavior as the former property. - -- v3.12.4(TBD) - - Fixed a bug where multipart uploads to Azure would be missing their MD5 hashes. - - Fixed a bug where OpenTelemetry header injection would sometimes cause Exceptions to be thrown. - - Fixed a bug where OCSP checks would throw TypeError and make mainly GCP blob storage unreachable. - v3.12.3(October 25,2024) - Improved the error message for SSL-related issues to provide clearer guidance when an SSL error occurs.

To restore them faithfully on the server-side and avoid introducing yet another layer of indirection, we would like to use the HTTP Request Id. Currently, this Request Id is generated on the client as part of issuing the query. With this PR we introduce a new (client-side) statement parameter requestId that allows to overwrite the automatically generated request Id. requestId must be a valid UUID4 or UUID4 string.

experimental support for OAuth authorization code and client credentials flows. - Improved error message for client-side query cancellations due to timeouts. - Added support of GCS regional endpoints. - Added `gcs_use_virtual_endpoints` connection property that forces the usage of the virtual GCS usage.

Added `infer_schema` parameter to `write_pandas` to perform schema inference on the passed data. + - Namespace `snowlake` reverted back to non-module. + +- v3.17.0(August 16,2025) + - Added in-band HTTP exception telemetry. + - Added an `unsafe_skip_file_permissions_check` flag to skip file permission checks on the cache and configuration. + - Added `APPLICATION_PATH` within `CLIENT_ENVIRONMENT` to distinguish between multiple scripts using the Python Connector in the same environment. + - Added basic JSON support for Interval types. + - Added in-band OCSP exception telemetry. + - Added support for new authentication methods with Workload Identity Federation (WIF). + - Added the `WORKLOAD_IDENTITY` value for the authenticator type. + - Added the `workload_identity_provider` and `workload_identity_entra_resource` parameters. + - Added support for the `use_vectorized_scanner` parameter in the write_pandas function. + - Added support of proxy setup using connection parameters without emitting environment variables. + - Added populating of `type_code` in `ResultMetadata` for interval types. + - Introduced the `snowflake_version` property to the connection. + - Moved `OAUTH_TYPE` to `CLIENT_ENVIROMENT`. + - Relaxed the `pyarrow` version constrain; versions >= 19 can now be used. + - Disabled token caching for OAuth Client Credentials authentication. + - Fixed OAuth authenticator values. + - Fixed a bug where a PAT with an external session authenticator was used while `external_session_id` was not provided in `SnowflakeRestful.fetch`. + - Fixed the case-sensitivity of `Oauth` and `programmatic_access_token` authenticator values. + - Fixed unclear error messages for incorrect `authenticator` values. + - Fixed GCS staging by ensuring the endpoint has a scheme. + - Fixed a bug where time-zoned timestamps fetched as a `pandas.DataFrame` or `pyarrow.Table` would overflow due to unnecessary precision.

Now /accelerate is not attempted. - -- v3.18.0(October 03,2025) - - Added support for pandas conversion for Day-time and Year-Month Interval types - -- v3.17.4(September 22,2025) - - Added support for intermediate certificates as roots when they are stored in the trust store - - Bumped up vendored `urllib3` to `2.5.0` and `requests` to `v2.32.5` - - Dropped support for OpenSSL versions older than 1.1.1 - v3.17.3(September 02,2025) - Enhanced configuration file permission warning messages. diff --git a/src/snowflake/connector/aio/_cursor.py b/src/snowflake/connector/aio/_cursor.py index b45e4aff38..57187c47c5 100644 --- a/src/snowflake/connector/aio/_cursor.py +++ b/src/snowflake/connector/aio/_cursor.py @@ -1279,8 +1279,7 @@ async def wait_until_ready() -> None: await self.connection.get_query_status_throw_if_error( sfqid ) # Trigger an exception if query failed - klass = self.__class__ - self._inner_cursor = klass(self.connection) + self._inner_cursor = SnowflakeCursor(self.connection) self._sfqid = sfqid self._prefetch_hook = wait_until_ready diff --git a/src/snowflake/connector/cursor.py b/src/snowflake/connector/cursor.py index 91f54bcf0f..a8ec738986 100644 --- a/src/snowflake/connector/cursor.py +++ b/src/snowflake/connector/cursor.py @@ -1749,8 +1749,7 @@ def wait_until_ready() -> None: self.connection.get_query_status_throw_if_error( sfqid ) # Trigger an exception if query failed - klass = self.__class__ - self._inner_cursor = klass(self.connection) + self._inner_cursor = SnowflakeCursor(self.connection) self._sfqid = sfqid self._prefetch_hook = wait_until_ready diff --git a/test/integ/aio_it/test_async_async.py b/test/integ/aio_it/test_async_async.py index 8dcdb936d6..024e53eb81 100644 --- a/test/integ/aio_it/test_async_async.py +++ b/test/integ/aio_it/test_async_async.py @@ -11,20 +11,22 @@ import pytest from snowflake.connector import DatabaseError, ProgrammingError +from snowflake.connector.aio import DictCursor, SnowflakeCursor from snowflake.connector.constants import QueryStatus # Mark all tests in this file to time out after 2 minutes to prevent hanging forever pytestmark = pytest.mark.timeout(120) -async def test_simple_async(conn_cnx): +@pytest.mark.parametrize("cursor_class", [SnowflakeCursor, DictCursor]) +async def test_simple_async(conn_cnx, cursor_class): """Simple test to that shows the most simple usage of fire and forget.
