test_cProfile has been disabled in Py3k for a while now. It should be
fixed before release.

A key thing to realize is that test_cprofile has heavily changed in
2.6 compared to what is currently disabled in 3.0.

I will try to fix this one with profile/cProfile merge.

Alexandre, are you still computerless?

Not anymore! :-)

So is this going to be a 3.1 issue or a 3.0 one? If it's the former then
it should not be a release blocker. But if is going to be for 3.0 then
the version list is wrong.

I guess since this hasn't been done by now, it's not going to get done
for 3.0, so I'm lowering the priority on it.

Done in r66817.

Have you verified the numbers? They don't look right to me.

The problem is the 2nd argument of cProfile's constructor has a
different semantic meaning than the one for For,
it is used to set the "bias" (I presume it means the overhead) of the
profiler. But for cProfile, it's the unit (in seconds?) of timer used.

Personally, I have no idea which semantic should be preferred. So
perhaps, the best thing to do for now is remove the second argument from
the cls.profilerclass() call in test_profile.ProfileTest:

class ProfileTest:
    def do_profiling(cls):
        prof = cls.profilerclass(timer, 0.001)

No, I didn't look too hard at it; I just got it scraping along, so I can
forward port a fix for it. I'll reopen this, so you can take more
action, so you wish. :)

Unassigning myself as I don't have the time to fix this properly.

Is there anybody who can run with this as it's been in limbo for over two years?
msg111996 - (view) Author: Mark Lawrence (BreamoreBoy) * Date: 2010-07-29 20:34
Nobody has responded to msg109475 so I'll close unless there are any objections.

> I'll close unless there are any objections.

Yes, I object! :)

If there's still a bug present, it seems inappropriate to close this issue.  So as a first step, someone needs to look at this closely to determine whether there *is* still a problem that needs fixing.  (It's not clear to me at the moment whether that's true.)
