Subject: [Montreal-pm] the mod_perl question and profiling web apps
Message-ID: <4F327DEE.70805@inverse.ca>

For those who attended the meetings, André sent me his config and it is
now resolved: he is using mod_perl.

But he still has a performance issue then.. So I told him to look at
Devel::NYTProf::Apache. Anyone here with experience with that?

I hope to try it soon.

Devel::NYTProf PLUG: {

For shell initiated perl, I've used Devel::NYTProf and I have to say
it's awesome! and if you've never used it, you should! Very easy to use
just call your script with `perl -d:NYTProf <script>` then run
`nytprofhtml`. Reports are all in interactive HTML with graphs, etc.
Works on daemons too.

For instance, I spotted that for a script we call often, there's a 25%
(250ms) cost just by having 'use diagnostics;' somewhere in the
dependency chain.. I didn't know diagnostics had a performance penalty...

}

Cheers!

+1 for Devel::NYTProf. This module is the most comprehensive Perl 
profiler I've seen out there...

I've used it in the past to spot slow deep cloning of data structures. 
15 mins later,
a quick trip to CPAN and a couple of s/Storable::dclone/Clone::clone/g, 
we had improved our
data copying by ~20%.

I never used Devel::NYTProf::Apache, but I expect the same level of 
awesomeness and
eye-opening moments!

Aye merci les gars! Cela dit, perdez pas trop de temps avec ça. L'idée de 
Olivier était la suivante: si quelqu'un a déjà essayé 
Devel::NYTProf::Apache, tant mieux, sinon je vais l'essayer moi-même car 
c'est pour ma job après tout... La bonne nouvelle, c'est que j'ai récupéré 
le PC industriel sur lequel on avait installé Linux pour fins de tests... et 
il est intact! J'ai taponné un peu dessus l'autre jour: quelle bouffée de 
fraîcheur par rapport à Micromou Châssis!

Subject: [Montreal-pm] Command line tool application framework
Message-ID: <4F40209C.2030309@inverse.ca>

Bonjour,

Je vais batir une très simple application CLI. Tant qu'à faire je me 
suis dit que ça serait plaisant de profiter de l'opportunité pour 
utiliser un des frameworks existants (car je pense convertir notre 
grosse application au travail).

Alors, quelqu'un a une opinion sur un de ses frameworks?

App::Cmd
App::Framework
CLI::Application
CLI::Dispatch
CLI::Framework
MooseX::App::Cmd

ou a une autre suggestion?

J'ai lu http://www.perlmonks.org/?node_id=829276, vérifié vite vite la 
POD des différents modules et je penche pour MooseX::App::Cmd (car je 
vais aussi toucher à Moose) mais je voulais avoir votre opinion.

A+
p.s.: je sais, j'ai pas élaboré sur mes requis mais vu qu'il y a deux 
applications (une toute simple inexistante et une au travail immense et 
que je veux rendre plus testable et performante), l'élaboration de mes 
requis aurait été plus mélangeant qu'autre chose (et aussi je dois aller 
préparer le souper ;) )

Subject: [Montreal-pm] building command line interfaces
Message-ID: <4F4EEEE7.3060305@inverse.ca>

Hi,

I'm looking for a module that does pretty command line interfaces. It 
does not need to be interactive and I would prefer if it would be simple.

It's for yet-another-of-Olivier's-open-source-project: dhcp0f[1].

I know there is perl's "formats"[1] but I remember reading something 
like: avoid this at all cost.. Or was it even Larry that said himself 
that he wasn't proud of that..?

Anyways, the data is like:

The header between rows of -----, are actually hardcoded with printf's 
but for the summary table it won't be as easy as I don't know how long 
the digit strings will be and it could be really long! So something that 
would detect shell's width and maybe shorten if it knows it won't fit 
would be really nice!

On my radar:
- Text::ASCIITable

Any other suggestions I overlooked? Is perlform really not recommended?
