The "thin_mode" flag contains the current state: None: neither thick nor thin implementation has been used yet False: thick implementation is being used True: thin implementation is being used The "requested_thin_mode" is set to the mode that is being requested, but only while initialization is taking place (otherwise, it contains the value None): False: thick implementation is being initialized True: thin implementation is being initialized The condition is used to ensure that only one thread is performing initialization. cCsd|_d|_t|_dSN) thin_moderequested_thin_mode threading Condition conditionselfr M/var/www/Datamplify/venv/lib/python3.10/site-packages/oracledb/driver_mode.py__init__AszDriverModeManager.__init__cCs|Srr r r r r __enter__FszDriverModeManager.__enter__cCsf|j&|dur|dur|dur|jdur|j|_d|_|jWddS1s,wYdSr)r rrnotify)r exc_type exc_valueexc_tbr r r__exit__Is  "zDriverModeManager.__exit__cCs|jdur|jS|jSr)rrr r r rthinUs zDriverModeManager.thinN) __name__ __module__ __qualname____doc__rrrpropertyrr r r rr1s rcCstjitjdur$tjdurtjtjdur#|dur dt_n4|t_n(|durD|tjkr\|r6ttjn.ttjWdtSWdtSWdtSWdtSWdtSWdtS1sowYtS)zw Returns the manager, but only after ensuring that no other threads are attempting to initialize the mode.

Immediately after python-oracledb is imported, this function will return *True* indicating that python-oracledb defaults to Thin mode. If a call to :func:`oracledb.init_oracle_client()` returns successfully, then a subsequent call to ``is_thin_mode()`` will return False indicating that Thick mode is enabled. Once the first standalone connection or connection pool is created, or a successful call to ``oracledb.init_oracle_client()`` is made, or :meth:`oracledb.enable_thin_mode()` is called, then python-oracledb’s mode is fixed and the value returned by ``is_thin_mode()`` will never change for the lifetime of the process. The attribute :attr:`Connection.thin` can be used to check a connection's mode. The attribute :attr:`ConnectionPool.thin` can be used to check a pool's mode.
