Comment (by jdemeyer):
There is a potential infinite loop with `_eval_line` in `gap.py`: when it
crashes, it keeps trying again over and over:
{{{
def _eval_line(self, line, allow_use_file=True, wait_for_prompt=True,
restart_if_needed=True):
[...]
try:
[...]
except (RuntimeError,TypeError),message:
if 'EOF' in message[0] or E is None or not E.isalive():
print "** %s crashed or quit executing '%s' **"%(self,
line)
print "Restarting %s and trying again"%self
self._start()
if line != '':
return self._eval_line(line,
allow_use_file=allow_use_file)
else:
return ''
else:
raise RuntimeError, message
}}}
Is this intentional? Probably the number of retries should be limited.
