Re: [RFC] Dynamic image generator handler
Hi, I am a little bit late for this thread, but anyway... I looked at Apache::ImageMagick last night however, and although it seems pretty usefull, it doesn't really address what I want to do with my module. I read your original RFC and as far as I see you can do everything you have requested with Apache::ImageMagick. What are you missing? Beside the fact that your benchmark shows that ImageMagick is slower then GD (but ImageMagick also handle a lot more picture formats then GD, for example I use it to convert TIFF input files to jpeg) What about the idea from Ed, to have one module, where you can drop in different backends? Would this be an idea to extent Apache::ImageMagick, so that it can use other grapical libraries?

MVC advice..?
Hi, I'm building an MVC architecture site and have hit a design issue. I have varoius Control subclasses which relate to different templates with different behaviour. Now my problem is that I have to assign which Subclass I want to instantiate, based on the script and params. I my last effort I went for a Shared datastructure holding (script, control module pairs) which then allowed one to be dynamically eval 'use..''ed in the main content handler. I found that clunky. I'm building from scratch again and am thinking of just firing up a template and allowing the control to be loaded INTO the view as a template toolkit plugin. What I hate about this is that I'm surrendering my View layer. Is there a neat way of dynamically loading in the appropriate control subclass? Something proven and widely used.

Re: mod-perl_2.0
At 00:25 29.05.2002, Kent, Mr. John wrote: Now my question. In the older version,(126) mod-perl created a larger (heavy) webserver. I could then add a startup.pl file to its http.conf file which used Apache::Registry to load perl and my modules. I don't see how this works in the new version of mod-perl, because I don't see a larger version of the httpd server anywhere. When I did the install it just seemed to load into the Perl 5.6.1 libraries. We'll need some more information about your build process... Normally, you specify the Apache Prefix (or the location of apxs) when running perl Makefile.PL. Then, you run make for mod_perl, ./configure and make for Apache 2.0, make test for mod_perl and I guess finally make install on both parts. You should see the mod_perl 2 installation documents: http://perl.apache.org/release/docs/2.0/user/index.html Did notice in the overview The details of these optimizations from the most part are hidden from mod_perl users, the exception being that some will only be turned on with configuration directives. A few of which include: * Inlined Apache::*.xs calls But not sure how to use it. This isn't really related to your question.. Look through the documentation, but for the most part these optimizations happen without you noticing. -- Per Einar Ellefsen [EMAIL PROTECTED]

RE: dso
I have to agree with this statement. We have a server farm with 15 apache servers running mod_perl as a DSO (not counting the several development and QC servers) with no problems. IMHO mod_perl as a DSO probably had problems in the beginning, but I couldn't confirm that without some research and I'm too lazy to do it, and as a result people now recommend compiling mod_perl into httpd. So I would say if DSO works for you use it, if not don't use it. -Original Message- From: Per Einar Ellefsen [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 29, 2002 6:54 AM To: Arnold van Kampen Cc: [EMAIL PROTECTED] Subject: Re: dso At 11:41 29.05.2002, Arnold van Kampen wrote: Hi Some messages ago, someone still mentioned that modperl had been - compiled in -, when describing his configuration, that he was having trouble with.

RE: MVC advice..?
Is there a neat way of dynamically loading in the appropriate control subclass? Something proven and widely used. For what it's worth, I use the eval trick too. Although it may seem a little clunky, I believe it is proven and widely used. The DBI.pm module uses code like this to load in the DBD drivers: my $driver_class = DBD::$driver; eval package DBI::_firesafe; require $driver_class; I'm not sure this answers your MVC questions, but maybe it will make you feel more comfortable with your solution. hth, aaron

Based on this, I would expect the content to be set to text/html and the

Galeon identifies the content type as application/x-perl. This would
seem to indicate to me that Apache is serving the script directly
instead of executing the script and serving the output. According to
the mod_perl Guide, the ExecCGI option (which I have set for Location
/perl) is supposed to avoid this situation.

separating C from V in MVC
We're developing a pretty complex web app using mod_perl and Mason and I'd like to use some form of MVC structure to keep things manageable. I'm looking for some pointers on MVC in this context. Specifically, M is easy ... use Perl objects, but how are others implementing the Controllers and Views in order to keep them separate? If I understand correctly, the Mason component that generates the page the user sees would be considered the View. But where is the Controller? I assume that, conceptually, the Controller is the code that responds to a given web request and decides which view to display. This is code I would normally have put in the %init section of the display component (with a possible redirect to another component based on application logic). This sounds like C and V are not separated as they should be. What's the right way to do it?

I wrote a little about this in my templating guide, and there has been discussion on the Mason list. A common approach is to use Mason's autohandlers as controllers, but you could really use any component. Just have it do some work in perl, gather some data, and then pass it off to a view component that generates the HTML. This is code I would normally have put in the %init section of the display component (with a possible redirect to another component based on application logic). This sounds like C and V are not separated as they should be. That's a standard way to do it in Mason, but not an MVC way. To make it more MVC, you need to have separate components for C and V, with V just receiving data and displaying it in HTML. - Perrin

Re: Reloading Modules
Ted Prah wrote:
Hi again,
I'm having trouble seeing module changes when I reload
a script that uses it.
That's because Reload.pm doesn't re-exports the symbols when reloading
the module and test.pl doesn't call import() because it sees the module
in %INC, therefore it still sees the old sub till the moment it gets
recompiled. Below you will find a complete analysis.
I'm using Apache::Reload and my test
script/module is as follows:
test.pl
#!/usr/local/bin/perl
use strict;
use warnings;
use My::Test qw(:subs);
print Content-type: text/plain\r\n\r\n;
test1();
Test.pm
package My::Test;
use strict;
use warnings;
BEGIN {
use Exporter ();
our (@ISA, @EXPORT, @EXPORT_OK, %EXPORT_TAGS);
@ISA = qw(Exporter);
@EXPORT= qw();
@EXPORT_OK = qw();
%EXPORT_TAGS = (
subs = [qw(test1)],
);
Exporter::export_ok_tags('subs');
}
sub test1 { print In test1 func\n; }
1;
adjust the test.pl to do:
test1(); print \test1, \n;
#test2(); print \test2, \n;
and My::Test.pm to:
...
warn test1:, \test1, \n;
#warn test2:, \test2, \n;
sub test1 { print In test1 func\n; }
#sub test2 { print In test2 func\n; }
...
The first time you run the script you will see:
output:
In test1 func
CODE(0x85ad38c)
error_log:
test1:CODE(0x85ad38c)
you can see that both test1 and My::Test::test1 point to the same sub.
When I modify sub test1, and I reload - no changes appear
in the browser. The following gets printed to error_log:
Subroutine test1 redefined at /export/home/httpd/cgi-bin/My/Test.pm line 22.
output:
In test1 func
CODE(0x85ad38c)
error_log:
test1:CODE(0x84ee110)
as you see the test1 is not the same as My::Test::test1
When I touch test.pl - the changes appear. The following gets printed
to error_log:
Subroutine test1 redefined at /export/home/httpd/cgi-bin/My/test.pl line 5
output:
In test11 func
CODE(0x84ee110)
now it points to the recent My::Test::test1
In that way you can debug any mysteries in Perl code.
Now, how to solve this problem. For example comment out
require $key;
in Reload.pm
that way, test.pl will see that My::Test is not in %INC, and require it
+ call its import() method.
Tell if this worked and we may adjust Reload.pm to have a special mode
where it makes Perl forget about modified modules and let the code that
loaded them in first place do the loading (and therefore the importing).
Finally, if I add a new subroutine test2 to Test.pm, export it, and
update the test.pl script to call test2, the script fails with an
Internal
Server Error. The following gets printed to error_log:
test2 is not exported by the My::Test module at
/export/home/httpd/cgi-bin/My/test.pl line 5

BEGIN failed--compilation aborted at /export/home/httpd/cgi-bin/
My/test.pl line 5.
Then, when I restart the server, the script runs fine.
Hmm, this one is different. Seems like a bug in Exporter.
if you remove Reload.pm from the setup, so it won't confuse you and
adjust the code to do:
do My/Test.pm;
My::Test-import(':subs');
you will see that it fails as well. This code acts like Reload.pm, but
always reloads the module. So it's not Reload.pm's fault.
Is anybody else familiar with this Exporter's (mis)behavior?
The solution that I see is to use something like this:
package My::Test;
use strict;
use warnings;
sub import {
my $package = shift;
no strict 'refs';
for (@_) {
*{ (caller)[0] . ::$_ } = \{$_};
}
}
sub test1 { print In test1 func\n; }
sub test2 { print In test2 func\n; }
1;
If somebody else can see the problem with Exporter may be we need to run
it through p5p.

Re: Persistent Net::Telnet Objects
Our project needed persistent socket connections open as well. There is
supposed to be a standard mechanism to pass file descriptors between unix
processes, though it's bugginess level depends on your OS. There is a perl
module for this called Socket::PassAccessRights. So what you can do is
create a daemon process that just hangs round holding socket connections
open, like a socket cache basically, and passing them back and forth between
Apache processes based on some session ID or user ID or the like.
Your daemon ends up looking something like this (with lots more error
checking of course)
my %sockmap;
while (1) {
my $clientsock = $listen-accept();
chomp(my $sessionid = $clientsock);
my $cachesock = ($sockmap{$sessionid} ||= opennewsock());
Socket::PassAccessRights::sendfd(fileno($clientsock), fileno($cachesock));
$clientsock-close();
}
And in your mod_perl code you do something like:
my $serversock = IO::Socket::INET-new(Server = 'localhost', Port =
SOCKETPOOLPORT);
print $serversock $sessionid, \n;
my $Fd = Socket::PassAccessRights::recvfd(fileno($serversock));
open(my $realsocket, =$Fd);
fcntl($realsocket, F_SETFD, 0);
my $ofh = select($realsocket); $| = 1; select ($ofh);
If you do some experimenting, you'll get something that works, you'll also
find lots of cases that don't.

Re: Persistant references [was] Persistent Net::Telnet Objects
I never do give enough info on the first e-mail. Thank you for bearing with
me...
What I mean is, if a request comes in for a certain form I would like to be
able to do something like this:
my $form = load_form($r);
$c{$session_id}-{handler} = $form-{handler}; # -- this being a code
ref...
$r-send_http_header;
print $form;
Then when the user completes the form and resubmits:
my $handler = $c{$session_id}-{handler};
$r-send_http_header;
print $handler-($r);
This is definately simplified, but the idea is there. I would like to be
able to store anything that can be referenced and have it be available to
all processes. I would like to be able to dynamically create anonymous
subroutine handlers based on input and have them be active until the form is
submitted, at which time they are used to process the form then discarded.
Is this something that can be accomplished? The global hash using Perl
aliasing
(http://thingy.kcilink.com/modperlguide/perl/Using_the_Perl_Aliasing_Feature
_.html) works beautifully, until of course the form is submitted to another
httpd process, and I'm hoping to not have to limit myself to just one child.
Obviously this can't be serialized, but there has to be *some* way to do
this...

Subject: Persistant references [was] Persistent Net::Telnet Objects
Along these same lines I'm seeking a way to store a code reference into a
global hash that is shared among all processes. For example:
my $session_id = get_session_from_cookie($r);
my $handler = $c{$session_id}-{handler};
$r-send_http_header;
print $handler-($r);
return OK;
Has anyone performed this kind of magical tidbit before? Is there some
main
process repository that I can access?

Our project needed persistent socket connections open as well. There is
supposed to be a standard mechanism to pass file descriptors between
unix
processes, though it's bugginess level depends on your OS. There is a
perl
module for this called Socket::PassAccessRights. So what you can do is
create a daemon process that just hangs round holding socket connections
open, like a socket cache basically, and passing them back and forth
between
Apache processes based on some session ID or user ID or the like.
Your daemon ends up looking something like this (with lots more error
checking of course)
my %sockmap;
while (1) {
my $clientsock = $listen-accept();
chomp(my $sessionid = $clientsock);
my $cachesock = ($sockmap{$sessionid} ||= opennewsock());
Socket::PassAccessRights::sendfd(fileno($clientsock),
fileno($cachesock));
$clientsock-close();
}
And in your mod_perl code you do something like:
my $serversock = IO::Socket::INET-new(Server = 'localhost', Port =
SOCKETPOOLPORT);
print $serversock $sessionid, \n;
my $Fd = Socket::PassAccessRights::recvfd(fileno($serversock));
open(my $realsocket, =$Fd);
fcntl($realsocket, F_SETFD, 0);
my $ofh = select($realsocket); $| = 1; select ($ofh);
If you do some experimenting, you'll get something that works, you'll
also
find lots of cases that don't.

OpenSSL/0.9.6a
on
Windows 2000 with PHP 4.21
I am working on a project that requires me to have two telnet objects
per
user session opened, and accessible throughout the user's session. I
have
looked at Apache::Session and many other solutions but my problem is
that
to
keep a Net::Telnet object, I need to keep open sockets and
filehandles,
so
I
cannot serialize the object and store it in a database or file.
Currently I have similar code working flawlessly:
###
# startup.pl - called when apache starts (ie. PerlRequire
d:/Apache/conf/startup.pl)
##
use MySite::Session;
###
# Session.pm
##
@EXPORT = qw( %sessionHash );
our %sessionHash;
###
# init_session.pl - called IN MOD_PERL when a new session is
requested
##
use MySite::Session;
$sessionHash{$session_id . _telnetObj} = Net::Telnet-new();
###
# dostuff.pl - called IN MOD_PERL many time throughout the session
##
use MySite::Session;
my telnetObj = $sessionHash{$session_id . _telnetObj};
bless (\$telnetObj, Net::Telnet);
Although this is working right now, I don't know enough [ anything?
:) ]
about Apache or mod_perl to be sure that this will work in the future.
What
I am really concerned
Re: Persistant references [was] Persistent Net::Telnet Objects
You could just pass around a string rather than a subref:
my $handler = 'sub { my $arg = @_; do_something(); }';
vs
my $handler = sub { my $arg = @_; do_something(); };
When you want to call it later on you do it like:
eval($handler)-('foo');
vs
$handler-('foo');
