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. rNFcCs||_d|_||_||_||_||_d|_d|_d|_t j |_ t j d7_ |j j |||f|jkr||j||fj |n|g|j||f<dS)NTrr)rbfunc_first_executable_linerlr%rKraenabledignorehitsrnextrJrpr`re)rrlr%rKrarbr r r rs zBreakpoint.__init__cCs>|j|jf}d|j|j<|j|j||j|s:|j|=dS)N)rlr%rprJrerf)rindexr r r rh s    zBreakpoint.deleteMecCs d|_dS)NT)r)rr r r enableszBreakpoint.enablecCs d|_dS)NF)r)rr r r disableszBreakpoint.disablecCs"|dkrtj}t|j|ddS)N)rl)rXstdoutr-bpformat)routr r r bpprintszBreakpoint.bpprintcCs|jr d}nd}|jr |d}n|d}d|j||j|jf}|jrT|d|jf7}|jrj|d|jf7}|jr|jdkrd }nd }|d |j|f7}|S) Nzdel zkeep zyes zno z%-4dbreakpoint %s at %s:%dz stop only if %sz ignore next %d hitsrrz" breakpoint already hit %d time%s)rKrrJrlr%rarr)rZdispZretZssr r r rs$  zBreakpoint.bpformatcCsd|j|j|jfS)Nzbreakpoint %s at %s:%s)rJrlr%)rr r r __str__6szBreakpoint.__str__)FNN)N)rr r r rrerprrhrrrrrr r r r rs   cCsN|js|j|jkrdSdS|jj|jkr,dS|js:|j|_|j|jkrJdSdS)z;Check whether we should break here because of `b.funcname`.FT)rbr%rFr7rr)br/r r r checkfuncname;s  rc Cstj||f}x|D]}|js qt||s,q|jd7_|jsf|jdkr\|jd8_qq|dfSqy)r-)ar r r rs rcCst}|jddS)Nzimport bdb; bdb.foo(10))rr)rr r r testsr)r rBrXrinspectrrr__all__r9 Exceptionrrr[rrrIrrrrr r r r s&  OZ0
