DateTime with Apache::SmallProf
Apologies for the X-post. It seemed appropriate.
I'm trying to profile a web environment (Apache 1.3.33/Perl 5.8.7/mp 1.29)
with Apache::SmallProf, however I seem to be getting some odd behaviour
from DateTime when smallprof is enabled.
We have a module using DateTime.pm, which is used in a CGI script, eval'ed
by Apache::Registry. It appears that DateTime throws a locale error on
the 'use DateTime' which gets propogated back through our module and onto
Registry. However this 'only' occurs when Apache::DB and
Apache::Smallprof are enabled.
I've snooped in DateTime and am not sure how SmallProf is causing this
error, so I'm hoping that someone else may be familiar with the
symptoms?
The error:
[Tue Jan 23 17:57:26 2007] bvsm.pm: [Tue Jan 23 17:57:26 2007] bvsm.pm:
You cannot replace an existing locale ('') unless you also specify the

Any suggestions would be appreicated.

I'm not a big profiling expert, but I've heard rumors around work that
we could never get Apache::DProf to really work (due to some magic in
own own code), but that the apache hooks in Devel::Profiler worked much
better. ymmv.

Since you put it like that, I stand corrected and don't know what I had
been thinking. :) DProf does not seem to be causing DateTime to die, and
I suppose that while resolving my problem, it still leaves the original
question open as an X-File.

Usually that's the reason you use DProf -- it gives you the big
picture. SmallProf is only useful when you've got it down to one sub
and you can't figure out which lines in the sub are taking the time.

No idea about that. Sounds like a classic case of too much magic in
one module or the other. You'd have to dig in and run it through the
debugger if you really want to solve that.

The code base I'm profiling is very big, monolithic and convoluted. I
felt that level of granularity given by smallprof would probably give me
more coverage - which I believe I need.
In any case, I can't see why it causes DateTime to carp?
Thoughts still welcome?
Thanks,
Raf

Mot off the top of my head, why are you using Apache::SmallProf and not
Apache::Dprof -- the previous is usually too low level.
