Meant to be used as a brain-dead substitute so that threaded code does not need to be rewritten for when the thread module is not present.

Compatibility is maintained by making sure that ``args`` is a tuple and ``kwargs`` is a dictionary. If an exception is raised and it is SystemExit (which can be done by _thread.exit()) it is caught and nothing is done; all other exceptions are printed out by using traceback.print_exc(). If the executed function calls interrupt_main the KeyboardInterrupt will be raised when the function returns. z2nd arg must be a tuplez3rd arg must be a dictF� NT) �type�tuple� TypeError�dict�_main� SystemExit� traceback� print_exc� _interrupt�KeyboardInterrupt)Zfunction�args�kwargsr � r �%/usr/lib64/python3.6/_dummy_thread.pyr s c C s t �dS )z'Dummy implementation of _thread.exit().N)r r r r r r = s c C s dS )z�Dummy implementation of _thread.get_ident().

Compatibility is maintained by maintaining self.locked_status which is a boolean that stores the state of the lock. Pickling of the lock, though, should not be done since if the _thread module is then used with an unpickled ``lock()`` from here problems could occur from this class not having atomic methods. c C s d| _ d S )NF)� locked_status)�selfr r r �__init__c s zLockType.__init__Nr c C sH |dks |rd| _ dS | j s&d| _ dS |dkr@ddl}|j|� dS dS )a� Dummy implementation of acquire(). For blocking calls, self.locked_status is automatically set to True and returned appropriately based on value of ``waitflag``. If it is non-blocking, then the value is actually checked and not set if it is already acquired. This is all done so that threading.Condition's assert statements aren't triggered and throw a little fit.
