v3.8.0(April 04,2024)

• Improved externalbrowser auth in containerized environments
  • Instruct browser to not fetch /favicon on success page
  • Simple retry strategy on empty socket.recv
  • Add SNOWFLAKE_AUTH_SOCKET_REUSE_PORT flag (usage: SNOWFLAKE_AUTH_SOCKET_REUSE_PORT=true) to set the underlying socket's SO_REUSEPORT flag (described in the socket man page)
    • Useful when the randomized port used in the localhost callback url is being followed before the container engine completes port forwarding to host
    • Statically map a port between your host and container and allow that port to be reused in rapid succession with:
      SF_AUTH_SOCKET_PORT=3037 SNOWFLAKE_AUTH_SOCKET_REUSE_PORT=true poetry run python somescript.py
  • Add SNOWFLAKE_AUTH_SOCKET_MSG_DONTWAIT flag (usage: SNOWFLAKE_AUTH_SOCKET_MSG_DONTWAIT=true) to make a non-blocking socket.recv call and retry on Error
    • Consider using this if running in a containerized environment and externalbrowser auth frequently hangs while waiting for callback
    • NOTE: this has not been tested extensively, but has been shown to improve the experience when using WSL
• Added support for parsing structured type information in schema queries.
• Bumped platformdirs from >=2.6.0,<4.0.0 to >=2.6.0,<5.0.0
• Updated diagnostics to use system$allowlist instead of system$whitelist.
• Updated write_pandas to skip TABLE IF NOT EXISTS in truncate mode.
• Improved cleanup logic for connection to rely on interpreter shutdown instead of the __del__ method.
• Updated the logging level from INFO to DEBUG when logging the executed query using SnowflakeCursor.execute.
• Fixed a bug that the truncated password in log is not masked.
