Bring up a Python console in the Remote Control interpreter. This console will initially have access to a heapy constructor, named hpy, and a ready-made instance, named hp, and the target (see also the reset command). Other things may be imported as needed. After returning to the Annex (by q) or to the Monitor (by . or <Ctrl-C>), the data in the interactive console will remain there - and will be available till the next time the console is entered. But the data may be cleared and reset to the initial state - a new heapy instance will be created - by the 'reset' command of Annex. It should be noted that the interpreter thread under investigation is executing in parallell with the remote control interpreter. So there may be some problems to do with that if both are executing at the same time. This has to be dealt with for each case specifically.)re )rf rK )r r r r �help_int s zAnnex.help_intZ a1e55f5dc4c9f708311e9f97b8098cd3c C s� | j d }g }|| _g }|| j | j< td| j � ||| j d | j |g}|�� }|j|� |@ r�td| jd� xZt|�D ]>\}}|�|�|@ rttd| | jd� t|�|�j | jd� qtW ntd| jd� | `| j | j= d S )Nr[ �0� __builtins__zIsolation test failed.)re z)-- Shortest Path(s) to testobjects[%d] --zIsolation test succeeded.) r9 Z_a�_bname�eval�heapZisorf rK � enumerateZshpaths) r rc r[ �a�bZ testobjects�h�i�vr r r � do_isolatest# s, zAnnex.do_isolatestc C s t d| jd� d S )Nad isolatest ---------- Isolation test. Test that the target interpreter heap view is isolated from the data in the remote control interpreter. Data introduced here, eg in the interactive console, should not be seen in the heap as reported by hp.heap() etc. This is achieved by setting hp to not follow the calling interpreter root. However, this isolation may become broken. This test is intended to diagnose this problem. The test checks that none of a number of test objects is visible in the target heap view. If the test failed, it will show the shortest path(s) to each of the test objects that was visible.)re )rf rK )r r r r �help_isolatestA s zAnnex.help_isolatestc C s t d| jd� t d| jd� d S )Nz(To return to Monitor, type <Ctrl-C> or .)re z4To close this connection ('permanently'), type close)rf rK )r rc r r r �do_qP s z Annex.do_qc C s t d| jd� d S )Nz�q ----- Quit.
