My code is something like this:
while not_done:
try:
code()
except keyboardinterupt:
print "Menu:"
print " debug - run pdb"
print " resume - resume program"
print " abort - abort program"
...
command = raw_input("> ")
if command == "debug":
pdb.set_trace()
...
The idea is that code() is run in a loop executing data (in my case, a
single entry to a log file) and Ctrl-C pauses the program and pops up
a little menu. The problem is that in certain cases, code() may have
already altered data and breaking out and rerunning it will either 1)
lose data or 2) duplicate data.
The only real solution I can think of is catching the interrupt in a
separate thread which sets a flag telling the main thread to run pdb,
or abort or whatever, but ideally, I'd like to catch the exception and
somehow magically resume.
