Implements temporary breakpoints, ignore counts, disabling and (re)-enabling, and conditionals. Breakpoints are indexed by number through bpbynumber and by the file,line tuple using bplist. The former points to a single instance of class Breakpoint. The latter points to a list of such instances since there may be more than one breakpoint per line. r NFc C s� | | _ d | _ | | _ | | _ | | _ | | _ d | _ d | _ d | _ t j | _ t j d 7_ | j j | � | | f | j k r� | j | | f j | � n | g | j | | f <d S)NTr r )r_ �func_first_executable_lineri r# rI r^ �enabled�ignore�hitsr �nextrH rm r] rb )r ri r# rI r^ r_ r r r r � s zBreakpoint.__init__c C sT | j | j f } d | j | j <| j | j | � | j | sP | j | =n d S)N)ri r# rm rH rb rc )r �indexr r r re s zBreakpoint.deleteMec C s d | _ d S)NT)r� )r r r r �enable s zBreakpoint.enablec C s d | _ d S)NF)r� )r r r r �disable s zBreakpoint.disablec C s2 | d k r t j } n t | j � d | �d S)Nri )rU �stdoutr, �bpformat)r �outr r r �bpprint s zBreakpoint.bpprintc C s� | j r d } n d } | j r. | d } n | d } d | j | | j | j f } | j rw | d | j f 7} n | j r� | d | j f 7} n | j r� | j d k r� d } n d } | d | j | f 7} n | S) Nzdel zkeep zyes zno z %-4dbreakpoint %s at %s:%dz stop only if %sz ignore next %d hitsr r� � z" breakpoint already hit %d time%s)rI r� rH ri r# r^ r� r� )r ZdispZretZssr r r r� s$ zBreakpoint.bpformatc C s d | j | j | j f S)Nzbreakpoint %s at %s:%s)rH ri r# )r r r r �__str__3 s zBreakpoint.__str__)r r r r r� rb rm r re r� r� r� r� r� r r r r r � s c C sn | j s# | j | j k r d Sd S| j j | j k r< d S| j sT | j | _ n | j | j k rj d Sd S)z;Check whether we should break here because of `b.funcname`.FT)r_ r# rD r6 r� r� )�br. r r r � checkfuncname8 s r� c C s� t j | | f } x� | D]� } | j s/ q n t | | � sD q n | j d 7_ | j s� | j d k r� | j d 8_ q q� | d f Sq yS t | j | j | j � } | r� | j d k r� | j d 8_ q� | d f Sn Wq | d f SYq Xq Wd S)z�Determine which breakpoint for this file:line is to be acted upon.
