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 d7 _ | j j | � ||f| jkr|| j||f j | � n| g| j||f< d S )NTr r )rb �func_first_executable_linerl r% rK ra �enabled�ignore�hitsr �nextrJ rp r` re )r rl r% rK ra rb r r r r � s zBreakpoint.__init__c C s> | j | jf}d | j| j< | j| j| � | j| s:| j|= d S )N)rl r% rp rJ re rf )r �indexr r r rh 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 s" |d krt j}t| j� |d� d S )N)rl )rX �stdoutr- �bpformat)r �outr r r �bpprint s zBreakpoint.bpprintc C s� | j r d}nd}| jr |d }n|d }d| j|| j| jf }| jrT|d| jf 7 }| jrj|d| jf 7 }| jr�| jdkr�d }nd }|d | j|f 7 }|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)rK r� rJ rl r% ra r� r� )r ZdispZretZssr r r r� s$ zBreakpoint.bpformatc C s d| j | j| jf S )Nzbreakpoint %s at %s:%s)rJ rl r% )r r r r �__str__6 s zBreakpoint.__str__)FNN)N)r r r r r� re rp r rh r� r� r� r� r� r r r r r � s c C sN | j s| j|jkrdS dS |jj| j kr,dS | js:|j| _| j|jkrJdS dS )z;Check whether we should break here because of `b.funcname`.FT)rb r% rF r7 r� r� )�br/ r r r � checkfuncname; s r� c C s� t j| |f }x�|D ]�}|js qt||�s,q| jd7 _|jsf|jdkr\| jd8 _qq�|dfS qy<t|j|j|j �}|r�|jdkr�| jd8 _n|dfS W q |dfS qW dS )z�Determine which breakpoint for this file:line is to be acted upon.
