A new patch is posted to the wiki, implementing the above. All modes
will output like this when finished:
guesses: 0 time: 0:00:00:06 DONE (Mon Jun 6 19:03:01 2011) c/s:23055M
Also, I found a bug in single.c that has been there all the time since
we got ETA. The hundredths was just a copy of the integer, so it was
0.00%, 1.01%, 42.42% and so on.
As an even worse hack than the current code (or maybe not) I played with
changing all get_progress functions to use a double* instead of a char*
and return a progress with lots of decimals (though still only shown
with two). I also circumvented the 32-bit overflow check if
sizeof(time_t) > 4. I got really good estimates after a *very* short
time (given a stable c/s rate). Also, I got disencouraging ETA's when
running slow formats, like "Apr 1 12:34:56 1231432" (i.e. 1.2 million
years from now) when running -inc:all :-)
That last stunt has little value but I could post it if anyone wants to
try it or polish it.
