This is intended for use by standalone history tools. IPython shells use HistoryManager, below, which is a subclass of this.r � a� Path to file to use for SQLite history database. By default, IPython will put the history database in the IPython profile directory. If you would rather share one history among profiles, you can set this value in each, so that they are consistent. Due to an issue with fcntl, SQLite is known to misbehave on some NFS mounts. If you see IPython hanging, try setting this to something on a local disk, e.g:: ipython --HistoryManager.hist_file=/tmp/ipython_hist.sqlite you can also use the specific value `:memory:` (including the colon at both end but not the back ticks), to avoid creating an history file. ��helpT��configa* enable the SQLite history set enabled=False to disable the SQLite history, in which case there will be no stored history, no SQLite connection, and no background saving thread. This may be necessary in some threaded environments where IPython is embedded. z�Options for configuring the SQLite connection These options are passed as keyword args to sqlite3.connect when establishing database connections. �connection_optionsc C s t dd�S )NF)Zcheck_same_thread)�dict�r r r r �_default_connection_options� s z+HistoryAccessor._default_connection_options�dbc C s8 |d }t tjf}t||�s4d| jj|f }t|��dS )zCvalidate the db, since it can be an Instance of two different types�newz3%s.db must be sqlite3 Connection or DummyDB, not %rN)r r, � Connection� isinstance� __class__r r )r Zchangerj Zconnection_types�msgr r r � _db_changed� s �zHistoryAccessor._db_changedr � c sV t t| �jf i |�� |r || _z | j W n tyH | �|�| _Y n0 | �� dS )a� Create a new history accessor.
