web2py has a profiler

[mdipierro]

New in trunk (highly experimental)

web2py.py -F profiler.log

will log all requests with profile details in profiler.log. This makes
thing slower.
I am not sure this is the proper way of doing it. Any feed back will
be appreciated.

It should be trivial to build an app (or an admin page) to browse and
search the profiler.log file if it exists.

Massimo,

I just downloaded trunk and tried starting as normal and get:

WARNING:root:unable to import dbhash

but if i start with the command below it works fine.

Hi Wes,

Try with the attached patch.

PS: Massimo, im sending to you too, so if that is alright we can put it in
trunk.

That's better. Thank You.

By the way. Remember to install python-profiler.

Sorry this patch will not do.

there must be one locker or the apps are not serialized when
profiling.

I fixed it in trunk anyway (please check).

My Windows service still fails:

Traceback (most recent call last):

Add this line:

profiler_filename = None

to your options_std.py file.

Right - this bit my server too.
Needs documenting at least :/
Can this be made to fail gracefully if not present?
- not really backwards-compatible otherwise...

options.py works, thanks - back in business :)

OK. I made a change in trunk that will work without cProfile if no -F
option is specified.
