lp:~pythonregexp2.7/python/issue2636-09-01-01

Created by TimeHorse and last modified

Often times, a label-goto block can be simulated with a while or do-while loop. Unsure if the single loop of the issue2636-09-01 branch would be sufficiently efficient, this attempts to simulate the original engine by using 3 while loops, one representing the main loop of SRE_MATCH, the others simulating the entrance and exit labels which represent the simulation of a recursive function call. It also uses two new state variables, good and restart, to control the loop while loops.

Restored the proper code for the JUMP_BRANCH call the push a new
context onto the stack which seems to have survived in child branches
but have been lost here.

39084. By Jeffrey C. "The TimeHorse" Jacobs <email address hidden>

Backed out the RETURN_SUCCESS and RETURN_FAILURE removal and restored
those function calls because they ARE needed by the Triple-Loop code;
they set the loop flags in self.

were removed in an earlier revision. Restored code that was
accidentally removed in an earlier release.
