Cloud SQL now recommends creating connections via the mysql dialect using the URL format ``mysql+mysqldb://root@/?unix_socket=/cloudsql/:`` Pooling ------- Google App Engine connections appear to be randomly recycled, so the dialect does not pool connections. The :class:`.NullPool` implementation is installed within the :class:`_engine.Engine` by default. éN)Úwarn_deprecatedé)ÚMySQLDialect_mysqldbé©ÚNullPoolcCstj dd¡ d¡S)NÚSERVER_SOFTWAREÚz Development/)ÚosÚenvironÚgetÚ startswith©rrú‰/home/ubuntu/experiments/live_experiments/Pythonexperiments/Otree/venv/lib/python3.10/site-packages/sqlalchemy/dialects/mysql/gaerdbms.pyÚ_is_dev_environment+src@s4eZdZedd„ƒZedd„ƒZdd„Zdd„Zd S) ÚMySQLDialect_gaerdbmscCsVtdƒddlm}tƒrddlm}|S|j d¡r#ddlm}|Sddlm }|S)Nz»Google Cloud SQL now recommends creating connections via the MySQLdb dialect directly, using the URL format mysql+mysqldb://root@/?unix_socket=/cloudsql/:r)Úapiproxy_stub_map)Ú rdbms_mysqldbZrdbms)Úrdbms_apiproxy)Úrdbms_googleapi) rZgoogle.appengine.apirrrZapiproxyZGetStubZ!google.storage.speckle.python.apirr)ÚclsrrrrrrrÚdbapi0sÿ     zMySQLDialect_gaerdbms.dbapicCstS)Nr)rÚurlrrrÚget_pool_classOsz$MySQLDialect_gaerdbms.get_pool_classcCs,| ¡}tƒsd|d<|jd|d<g|fS)Nr ZdsnÚinstance)Ztranslate_connect_argsrÚquery)ÚselfrÚoptsrrrÚcreate_connect_argsTs z)MySQLDialect_gaerdbms.create_connect_argscCs@t d¡ t|ƒ¡}|r| d¡p| d¡nd}|rt|ƒSdS)Nz^(\d+)L?:|^\((\d+)L?,ré)ÚreÚcompileÚmatchÚstrÚgroupÚint)rÚ exceptionr"ÚcoderrrÚ_extract_error_code]s€ÿz)MySQLDialect_gaerdbms._extract_error_codeN)Ú__name__Ú __module__Ú __qualname__Ú classmethodrrrr(rrrrr/s   r) Ú__doc__r r Zsqlalchemy.utilrZmysqldbrÚpoolrrrÚdialectrrrrÚs   7
