[mp2] Apache2::Reload doesn't reload
It seems like I've tried everything, and I can't get Apache2::Reload to
reload my modules.
I have a handler in a module called JetSet::Handler. That module
depends on a number of other modules, which I've tried to include with
'use', with limited success. It seems, sometimes, symbols act just fine
and reload when they should, but other times, I have to restart Apache
in order to get the symbols to reload.
I have run the Reload debugger, and it says everything is reloading just
like it should. But, I believe my problem is described in the
Apache2::Reload documentation; Apache keeps the old function pointer
around from the first 'use', even though the changed function now has a
new pointer.
The Apache2::Reload documentation also says Registry (which I'm not
actually explicitly using) doesn't play nicely with Exporter when 'use'
is used, so I tried the 'require';'import()' method described in the
documentation. With this, I'm unable to import my symbols. For example:
# In Handler.pm:
require JetSet::Debug; JetSet::Debug-import();
# ...
JetSet::Debug::DebugLevel(JetSet::Debug::DEBUG_WARN);
# End
Where DEBUG_WARN is declared either by sub DEBUG_WARN() { 3 }; or with
'use constant' in Debug.pm. It is then exported in @EXPORT or
@EXPORT_OK. Any combination of these things gives the following error.
# From error_log:
failed to resolve handler `JetSet::Handler': Bareword
JetSet::Debug::DEBUG_WARN not allowed while strict subs in use at
/home/cww/sites/rain/htdocs/jet-set/JetSet/Handler.pm line 19.
# End
I read in the list archives that doing away with Exporter altogether
might be the preferred way of dealing with this. Implementing my
modules as objects instead of exporting functions, it seems, might
eliminate the not-exporting errors and make Reload work correctly:
http://www.gossamer-threads.com/lists/modperl/modperl/82283#82283
I'm not opposed to doing that, but in that case, how does one deal with
things like constants? Perhaps I would just have to keep all my
constants in a single Exporter-style file and then restart Apache every
time I change it? Frankly, that sounds like a pretty lousy way to have
to deal with this.
Here are some snippets that might help with the diagnosis.
# From my virtual host configuration:
PerlRequire /home/cww/sites/rain/htdocs/perl-static/startup.pl
PerlModule Apache2::Reload
PerlInitHandler Apache2::Reload
PerlSetVar ReloadDirectories /home/cww/sites/rain/htdocs
Location /jet-set
SetHandler perl-script
PerlResponseHandler JetSet::Handler
/Location
# End
# startup.pl:
use lib qw(/home/cww/sites/rain/htdocs/jet-set);
1;
# End
# Apache2 version string:
Apache/2.2.3 (Debian) mod_ssl/2.2.3 OpenSSL/0.9.8e
mod_apreq2-20051231/2.6.0 mod_perl/2.0.2 Perl/v5.8.8 Server at rain Port 80
# End
Thank you for your assistance.

Re: [mp2] Apache2::Reload doesn't reload
I've found Reload to work poorly on the handler sub -- i haven't been
able to figure out why, but it just works poorly.
To get around that, I just have the handler call/wrap other subs.
package myapp;
sub handler {
$page= myapp::Page-new();
$page-whatever;
}
any changes go into myapp Page, or other modules.
i never have to worry about the reload issues on the handler. pretty
simple.

So, Page.pm defines an object... do you have Page.pm including other
Exporter-style modules? And, do those work properly?
Thanks.

Plat_Forms: Results and Survey
Hi mod_perl users, some months ago I asked for Perl web development teams for the Plat_Forms contest. Now the results are published: http://www.plat-forms.org/2007/results/ http://www.plat-forms.org/2007/documents/platformsTR.pdf The research team of the Free University of Berlin created a survey for professional web developers and asked me to forward you the following invitation. http://www.plat-forms.org/survey/ So, I hope that a lot of Perl users say them, why they use Perl ... ;-) Ciao Alvar -- Forwarded Message -- From: Florian Thiel ... Subject: Re: Plat_Forms: It's not over yet! Dear Perl web developers, We are currently researching the ways in which the major web development platforms differ and in addition to our work with the Plat_Forms contest, we're now looking for actual professional opinions. If you have practical experience in the development of non-trivial web applications with two or more web development languages then we would like you to participate in a short survey. Three Perl teams participated in this year's Plat_Forms contest but we would like to get a broader perspective. The questionnaire asks you about your experiences and opinions on two of the web development languages you have used, and should take about 10-15 minutes to complete. To thank you for your participation, you will be able to provide an email address and we will send you our final report when we are finished compiling it. http://www.plat-forms.org/survey/ We look forward to your answers and experiences, let me know via email if you have any questions.

newbie questions
I've been trying to convert our app over to mod_perl. Everything went
smoothly except the cookies. When I load the page, some frames load and
other don't. Below is the Perl function which prints out the headers. It's
called before any template is printed. If I comment out the cookie lines,
and print out an empty header the frames load perfectly, albeit without any
session support. I'm sure this is a big time newbie question, but I'd
appreciate some help... I've been googling around for quite a while. Thanks
in advance. --Pubert
my $bDidHeader;
my $_cookies={};
#
sub printHeader {
#
my $contentType = shift;
$contentType = 'text/plain; charset=utf-8' if(!$contentType);
my $cgi;
my $sessCookie;
if(!$bDidHeader) {
my $objVP = VirtualPlant::getInstance();
if(! $objVP) {
use CGI;
$cgi = new CGI;
$sessCookie = '';
} else {
$cgi = $objVP-Cgi;
$sessCookie = $cgi-cookie( CGISESSID = $objVP-Session()-id
);
}
if($sessCookie) {
VirtualPlant::Util::setCookie($sessCookie);
print $cgi-header(
-cookie = values
%{VirtualPlant::Util::getCookies()}
);
}
$bDidHeader = VirtualPlant::TRUE;
}
}
