RE: [mp2][QUESTION]: Filter to modify request headers on a proxy server

Thanks for this. I had put 'PerlInputFilterHandler

been outside like you said.

PerlInputFilterHandler iPAQApache::ResetBrowser
Is this the correct directive?
The directive is correct, but you don't show your code and your config,
so I
have no idea if the rest is correct or not. This directive is used to
configure both, connection and request level filters. It's the attribute
of
the handler subroutine is what makes the difference and the placement in
httpd.conf.
You need to declare it as:
package iPAQApache::ResetBrowser;
use base qw(Apache::Filter);
sub handler : FilterConnectionHandler { your code is here }
1;
and you need to put it outside of Location or similar block in
httpd.conf
just like shown at:
http://perl.apache.org/docs/2.0/user/handlers/filters.html#Connection_In
put_Filters
Also make sure that you run at least mod_perl 1.99_09, or even better
the
current cvs. And in the future please follow the info at
http://perl.apache.org/bugs/ so we know more about your setup.

MP2 Apache Settings
Hello Group, Hope this isn't too apache related and considered off topic. I have a bunch of sites, each have their own IP. Some of those sites have subsites within them with different domain names, these subsites are virtual's based on domainname with all the same parent IP. If I have MP2 modules and location names that I want to share to specific IPs or Specific Virtual Hosts is there was way to define it once or does it have to be within each virtual host. For example: VirtualHost 10.0.0.5 ServerName domain1.com PerlModule YADDA::LoginLocation "/login" SetHandler perl-script PerlHandler YADDA::Login/Location /VirtualHost VirtualHost 10.0.0.5 ServerName domain2.com /VirtualHost VirtualHost 10.0.0.6 ServerName domian3.com /VirtualHost In the case above I want the module YADDA::Login and the location to be available to BOTH the .05 virtual hosts, but not the .06 - so both /domain1.com/login and domian2.com/login do the same thing but domain3 would not. Is the choice either global to everything or defined within each virtual that I want it? I've been reading the server and dir create/merge section on perl.apache.org but I'm not even sure it relates. Thanks -Chris

Re: Coding Style Question - Using exit
Thanks for the reply Thomas,
Why not let determine_proper_action() return undef (or OK, or whatever) if
you do not want to redirect? And in your handler do:
my $rv=determine_proper_action();
if ($rv) { # or ($rv == Apache::Constants::OK)
# redirect
} else
# done
}
One problem I can see is if you're exiting somewhere deep in a nested sub
and you cannot propagate the return value back to the handler (easily).
That seems to be working well, I've changed that part of the handler to:
**
($request_type,$back_url) = determine_proper_action();
# Properly Exit the Handler from all subs within Determine Proper Action
if ($request_type eq 'Apache::REDIRECT') {
$r-headers_out-set(Location = $back_url);
return Apache::REDIRECT;
} else {
return Apache::OK;
}
*
Then in every sub within determine_proper_action I'm returning either
Apache::OK or Apache::REDIRECT.
Still got a lot of testing to do, but so far I've been able to get rid of
all exits from my script!
Thanks

Coding Style Question - Using exit
Folks,
In the continuing effort to make my code better,
I'm trying to get rid"exit" in my scripts and clean up some things that
just don't sit well (but they work).
Almost 95% of my pages are served up via a template
system (H::T) and the rest are a redirects.
Currently I use a subroutine that all my other subs
pass content to, to display my templates- at the end of this sub I call
"exit" so I do not go any further.
In the case where I want to redirect to a URL, I
then "return" to the handler with the URL.
Although it works, it doesn't seem right to
me..
Example To Help Explain:
sub handler {$r = shift;
init_global_vals();
$back_url = determine_proper_action();
my $back_url =
"";$r-headers_out-set(Location =
$back_url);return Apache::REDIRECT;
}
"Determine proper action" is a dispatch list of all
the subroutines that make up the script, including the sub where I display the
templates and exit.
So for almost 95% of my requests, I'm "exiting"
within determine_proper_action().
Does that make sense? Is it a bad
thing?
Thanks

ANNOUNCE: OpenInteract 1.60 released
A new version (1.60) of OpenInteract has been released. OpenInteract is an extensible web application server built on Apache, mod_perl, the Template Toolkit and SPOPS object persistence. This release includes a handful of fairly small enhancements, including the ability to force everyone to login before seeing any part of your site. HTTP redirects (vs. using icky META tags in HTML) are also supported, and under certain circumstances we now force the Apache child into a premature death. Source: http://prdownloads.sourceforge.net/openinteract/OpenInteract-1.60.tar.gz?download Detailed changes: http://sourceforge.net/project/shownotes.php?release_id=178076 It's also winging its way around CPAN. Thanks!

Subject: $r-headers_out Location and Set-Cookie
I have the next problem, i am in page A that form points to page B, that
is
a modperl2 handler.
This handler makes a job and decides to send a cookie to the browser, and
after to redirect to the same page A who is ready to catch the cookie.
Then the problem is that if i put the two headers, i don't have the cookie
posted, but if i comment the Location header, then i stay at perl handler
location, and if i go manually to page A then i see that the cookie is
posted.
So why these two headers doesn't respect themselves?
Resuming
$r-headers_out-{'Set-Cookie'} = $cookie;
$r-headers_out-{'Location'} = $url;
Redirects the page to $url but cookie is not seen by browser
$r-headers_out-{'Set-Cookie'} = $cookie;
#$r-headers_out-{'Location'} = $url;
Location is the perl handler 'localhost/pageB/' (perl handler), if you then
go
to localhost/pageA (or simply click BACK button) then the browser DO see
the cookie!
Any idea?

Re: [OT] About XML and Petal (was Re: templating system opinions(axkit?))
On Mon, 28 Jul 2003, Aleksandr Guidrevitch wrote: May be I'm a bit late here... But is there any sence in artifical XML templating languages since there is XSLT ? Just wonder whether there are cons other than long learning curve and performance issues ? Well, in the case of just TAL/Petal, the point as far as I know isn't so much that it happens to be valid XML -- though of course that's a welcome design aspect -- but that it's easy to use in W3C compliant HTML without masking the interesting bits inside HTML comment blocks. I can't think of an example now (and apologize for only having had time to skim much of this long, spiralling thread so far), but I seem to remember that TAL's syntax allowed for these clever little inside out loop structures that, among other things, ensures that the unrolled version of the loop still has proper indentation etc. Unessential maybe, but a nice touch. I don't know nearly enough about XSLT to comment on it in depth, but my impression is that TAL generally derives from the same heritage as all the assorted Perl template languages, etc, rather than ...well I guess I don't really know where XSLT derives from (Docbook?), but it seems more like CSS: a separate document describing how to display one or more other structured documents. The difference in the case of TAL / TT / H::T / Mason / etc is that the template is used to provide that structure itself, assembling it out of code that is maybe extracting content from a database or calculating it on the fly something. My hunch is that the way to work XSLT into the mix -- if it has a place at all -- is to have your logic (scripts with H::T, code sprinkled in Mason templates, TT applied where clever TT people apply it) fleshing out the framework defined in a template (the H::T template, the non-code part of a Mason template, the plaintext part of a TT template) as well formed XML, and then using XSLT to format that intermediate form for display. This probably makes sense in cases where that intermediate form can be cached (pages for web or print that change once a day, say), but for truly dynamic documents the XSLT stage is probably way too much overhead. Is XSLT appropriate for applying both structure styling to the free- form output of a [Perl] program? Does it take a lot of overhead? Would this overhead happen on the server end (glue XML + XSLT into an HTML document that goes out over the wire), or on the client end (download XML, then grab XSLT by reference (like HTML grabs CSS), and then the client merges them)? If the client does the work, how widespread is support? If the server does the work, what should the throughput be like? My hunch -- which I'd be happy to be corrected about -- is that this can't be any easier than just working directly from traditional template kits, as has been discussed at remarkable length in this thread :) -- Chris Devers[EMAIL PROTECTED]http://devers.homeip.net:8080/resume/ sorry for helping along in this thread 10 days dozens of messages ago :)

That is what made me avoid Mason, it just blew my head off for complexity. Now it is true, I am looking for a bit more than what CGI::Application offers out of the box, but it may well end up being worthwhile to just extend rather than convert. I really appreciate the simple philosophy that HTML::Template and CGI::Application follow. OpenInteract definitely does more for you. But it also has (IMO) a fairly sophisticated way to distribute standalone applications -- including data structures, initial data, security settings, templates and (oh yeah) the actual perl code -- and plug them into another OI server. OI 1.x ties you to the Template Toolkit, but 2.x (a big improvement now in beta) allows you to use whatever templating engine you like. You lose a ton of functionality, but HTML::Template folks seem to like it that way :-) One question, how do you judge that OpenInteract is more established? Is does look like it is actively developed, but I never heard of it before, and I couldn't find much indication of how popular it is. Randal's 'far more established' may be premature :-) Taking a strict time perspective: from Backpan it looks like CGI::Application was first released to CPAN in July 2000, while OI was first released in February 2001. (I'd thought it was October 2000, but it's funny the tricks your memory will play.) As to other definitions of 'established' I haven't followed CGI::Application development to say either way. There have been more articles published on CGI::Application and it seems to have a larger userbase, partly because it's easier to get started with and wrap your head around everything it does.

I've briefly read up on the pros and cons of each, and am just wondering which one is the most widely _used_ and best to learn if you're wanting to know something that there are jobs for. What's best depends on what your requirements are. As far as I can tell, the big ones are Template::Toolkit, Mason, and HTML::Template; each one makes different tradeoffs and makes different assumptions about the division of labor among programmers, web developers, content producers. TT is probably the most flexible, but that or might not be what you want. Honestly, of the three I just listed, none of them are *that* complicated. If you want to learn these for job hunting purposes -- in which case it's not really fair to ask you what the requirements are, since you can't really know that -- you might as well experiment with all three.

That's what the Bricolage authors say at http://bricolage.cc/ Hmm, so it does. I wonder where I got the idea that it was H::T based... I'm very pleased with Mason -- the online O'Reilly book about Mason is at http://www.masonbook.com/book/ A little bird tells me that TT is about to get an O'Reilly book as well, though it's not on their upcoming titles page (yet). The only H::T dead-trees material that I know of is a section in _CGI Programming with Perl_, 2nd edition -- that's where I learned it. I like the simplicity of H::T, but most other people seem to prefer TT or Mason. I still think it comes down to whichever system meets your needs the best, and in different contexts any of them (or others) could be appropriate. This may have been covered before here, but Zope supports an interesting template mechanism called TAL, where everything is done by attributes for the HTML tags, rather than special logical tags as most other systems use (e.g. the ones mentioned above, SSI, PHP, ASP, JSP, etc). This has the nice side effect of guaranteeing that all your html templates are always valid, and so can be used in any html IDE without complication. So for example, picking a random sample from the spec: Repeat Syntax: argument ::= variable_name expression variable_name ::= Name When you want to replicate a subtree of your document once for each item in a sequence, you use repeat. The expression should evaluate to a sequence. If the sequence is empty, then the statement element is deleted, otherwise it is repeated for each value in the sequence. If the action is cancelled, then the element is left unchanged, and no new variables are defined. The variable_name is used to define a local variable and a repeat variable. For each repetition, the local variable is set to the current sequence element, and the repeat variable is set to an iteration object. You use iteration objects to access information about the current repetition (such as the repeat index). (Iteration objects are more properly the domain of TALES.) The repeat variable has the same name as the local variable, but is only accessible through the builtin variable named repeat (see RepeatVariable). Examples: p tal:repeat=txt python:'one', 'two', 'three' span tal:replace=txt / /p table tr tal:repeat=item here/cart td tal:content=repeat/item/index1/td td tal:content=item/descriptionWidget/td td tal:content=item/price$1.50/td /tr /table It's a pretty clever approach; I'd like to see something like this done with a Perl backend (I haven't really been keeping track of development, for all I know there already is a Perl backend...).

Re: mod_perl 1.0 and 2.0
There is a 0.92 version of Apache::DBIis mp2 aware (there may even be a later version at this point). We started with mp1 and do to problems we decided to goto mp2 (which turned out to be non mod_perl and apache related), there wasn't any major performance increase or anything like that and I don't remember anything major coming up during the switch (outside of cookies - which always seem to be a problem). I use a bunch of the popular modules like HTML::Template, Image::Magick, DBI, Parse/WriteExcel, Date::Manip etc and I haven't had any problems.

Re: advice on implementing a controller manager
Xavier Noria wrote: I am writing an application following MVC with Perl Apache modules and the Template Toolkit. Apache is 1.x. I would like to have just one entry point to the application, which would play the role of someone who sets everything necessary up and forwards the actual request to a selected handler. From what I have read, looks like implementing that controller as a PerlFixupHandler which would use push_handlers() and pass things via pnotes() would be fine, but I am not experienced in mod_perl. Would you suggest a different approach? A word of advice: if you'd like to use it under different web environments, create your own system for registering/calling handlers instead of using the Apache API. That is, have a map of URL-to-class and have your controller find the class to execute based on the URL and call it directly. This is how OpenInteract does it and it's saved quite a lot of grief. It also makes for nice decoupling which is always a good thing. Of course, you could use OpenInteract as an MVC framework that uses the Template Toolkit, but that's a different matter... :-) Chris -- Chris Winters ([EMAIL PROTECTED]) Building enterprise-capable snack solutions since 1988.

Re: errors installing libapreq [RESOLVED]
Well, I rebuilt Apache/mod_perl, and it seemed to work. For those that
hit the same error, the fix -- which I've saved as a script for future
reference :) -- is as follows:
* Install Apache/mod_perl:
#!/bin/sh
# chd.build.apachemodperl.sh
perl=/sw/bin/perl
modperldir=/usr/src/mod_perl-1.27
apachedir=/usr/src/apache_1.3.27
builddir=/usr/local/apache
pushd $modperldir

make

sudo make install
pushd $apachedir
sudo make install
echo Verifying that the build worked:
${builddir}/sbin/apachectl configtest \
echo congratulations, you may now reset apache by running \
echo ${builddir}/sbin/apachectl start
* Installation may disrupt Perl modules. I had to rebuild Apache::Test
% sudo /sw/bin/perl -MCPAN -e shell
cpan install Apache::Test
* Install libapreq:
% perl Makefile.PL \
-httpd /usr/local/apache/sbin/httpd \
-apxs /usr/local/apache/sbin/apxs
% make
% make test
% make install
Everything went smoothly up to the `perl Makefile.PL [...]` step, where I
got this error:
skipping test setup...Undefined subroutine Apache::Test::config called at
/sw/lib/perl5/site_perl/5.8.0/darwin/Apache/TestMM.pm line 90.
Warning: prerequisite Apache::Test 1.03 not found. We have unknown version.
And, as I say, rebuilding Apache::Test in the CPAN shell took care of
that. Others may hit different problems that could be fixed similarly.
All better now :)

Re: Apache Error of $r-read failed to read
I FOUND IT!!
Like you said, it was in CGI.pm. It happens when doing a file upload
##
while ($bytesread=read($image_filename_one,$buffer,1024)) {
print OUTFILE $buffer;
}
##
If during the upload the user stops, drops or dies then the errors come
through which makes me think now that its not as serious of a error as I
thought (meaning any ill effects I may have thought was a result of that
error message, really isn't).
At very least at least I know what causes it.
Thanks

From: Stas Bekman [EMAIL PROTECTED]
You probably use CGI.pm or something else that calls $r-read(). This
happends
in xs/Apache/RequestIO/Apache__RequestIO.h (hint grep the mod_perl source
code):
/*
* XXX: as stated in ap_get_client_block, the real
* error gets lots, so we only know that there was one
*/
ap_log_error(APLOG_MARK, APLOG_ERR, 0, r-server,
mod_perl: $r-read failed to read);
break;
As you can see from the comment due to a bad implementation of
ap_get_client_block in Apache, the error is not available. I'm planning to
rewrite all these functions to get rid of ap_get_client_block, and work
with
bucket brigades instead.
In any case that won't solve the problem that you are seeing, I'd dig in
Apache. e.g. trying to use mod_cgi (which doesn't use ap_get_client_block)
to
reproduce the problem and ask at the httpd list.

Re: is anybody using mp2 in production?
Our mod_perl success story. As consultants we were hired to repair, revamp and rebuild a online classifieds site in which a lot of cost and effort was placed in promoting the site and generating traffic but the site itself was based on a 3rd party product that simply could not handle the half million hits a day the site was getting. Without a lot of effort the decision was made to build a custom solution from the ground up using Perl and Apache under Linux. After completing the project and having some difficult issues with the current ISP we moved the entire site to an ISP that we have had a long term relationship with and who provides us with everything one would need to properly maintain such a project. Little did we know that the second we moved to our new ISP it was like opening up the flood gates (long story relating to other ISP), overnight this CGI driven site went from a half million hits a day to a million and with it came a number of problems, a lot of which were unfixable without adding more hardware - there was simply far too much traffic coming through during the peak times of the day. Having spent a week doing everything we could, optimizing everything possible it was clear that at best, we may be able to gain enough to just keep our heads above water. Reluctantly we knew we had no choice but to give mod_perl a try, we really didn't think it was going to make that much of a difference but every little bit counted at this point. We knew that it was going to be very difficult to setup apache and especially convert our code over - I mean after all I've heard as many stories of nightmare conversions as success stories. After about the first week of pouring through the documentation and experimenting on our development server, I realized HOW WRONG I WAS.. Once we understood what was expected, conversion of the current code was less painful and a lot more interesting to do then some of the phone calls or meetings that led up to getting the contract for the project itself J. Once everything was done we could see instantly the improvement on our dev server, what we didn't know nor what we were prepared for was what would happen once this was running in production, I mean sure it was fast when there is only 2 of us on the machine, so was the old site. What we saw after going live was one of those moments when you are just blown away, where you are sitting there saying I see it but I just don't believe it. At our best estimate we gained more then a 300% performance increase, during peak hours we were seeing load times of 20 - 30, processing going defunct etc. etc. prior to mod_perl. Since the day we went live we haven't seen the machines even sweat, even the DB machine was impacted by the change in a positive way. We are currently up over 2 million hits a day, the 1 million hits gained since going live with mod_perl has resulted in practically nothing (everything is still saying Give me More!!!) We'd like to think it was easy moving to mod_perl because we are such awesome coders, but of course the truth is it's due to the awesome documentation at http://perl.apache.org, the fantastic support of mod_perl in all those perl modules we have all come to depend on, the invaluable mailing lists and mailing list archives, and what I personally think is the coolest thing of all, Stas Bekman who never left me or anyone else I've seen on the mailing list hanging for any answer. We have just completed a re-design of the site and have been up and running under Apache 2 and mod_perl 2 for about 6 months now with as few problems as anyone could ever hope to have. Mod_perl is clearly the solution for high traffic sites, however because of our experience with mod_perl we have since done everything in it, from the simplest of form mailers to complex sites because in my eyes there is no reason not to do things the best possible way the first time around!

Not reading $ENV variable
Hi all,
I'm seeing a weird thing. Sometimes my script sees nothing in the
$ENV{HTTP_REFERER} variable. Im not sure what is causing this. It works
some of the time.
I do this at the begining of the script...heres the code:
my $r = Apache-request;
use DBI;# for connecting to the database
my $refer_url = $ENV{HTTP_REFERER};
basically the script takes form data and inserts it to a db then returns
back to the refering page.
Thanks for any ideas

Apache Error of $r-read failed to read
Hi, We have been having some problems where all of a sudden apache will start logging the error of: [error] mod_perl: $r-read failed to read Multiple times (100s in less then 10th ofa sec), often it will get to the point where load on the machine goes through the roof and apache has problems responding and it appears to be the number of requests that are happening as limits that shouldn't be reached like DB connections and apache processes are maxing out during non-peak hours. From what we could see it looked like someone outside was sending all kind of linefeeds and whatnot within the URL which was documented in the Apache 45 release which we did update - now we are down to getting the above mod_perl error and shortly after that starts all hell breaks loose. Nowhere in our code do we directly call the "read" method nor can I find anything relating to the error so I'm a little lost on what I can do. Any ideas?

Here is a bug report: http://tagteam.prevare.com/mp2bug.txt Here is the Error Log http://tagteam.prevare.com/mp2error.txt Here is a perl -V http://tagteam.prevare.com/perlver.txt At first I was getting a host of those errors that were Cannot Locate TeshHooks/init... , echo etc. I edited t/hooks/TestHooks/init.pm and added: PerlModule TestHooks::init PerlModule TestProtocol::echo PerlModule TestProtocol::echo_filter (Why almost all the init.pm errors went away but the one that is showing up is beyond me, the init.pm and protocol modules are within @INCs) As I saw in some other posts, after doing that those errors went away and I was left with what is in the logs above. I also saw some posts where there could be some permissions issues so I killed the whole directory, extracted it all again as a normal user, made the edits to init.pm, su'ed to root and tryed to install again - I got the same results.

RE: MP2 - New Install - Make Test Errors
Thanks Stas, I tried getting it via CVS and all those other problems went away but I have a new one.. Can't locate Apache/TestConfig.pm This happens right at the end of the make and the module is within @INC. I haven't seen any posts that relate to this problem, any idea? Here is the bug report, I don't see any error_log in the CVS version. Thanks -Chris -8-- Start Bug Report 8-- 1.

Using a Startup.pl
Hello All, This may be a stupid question, but I'm not finding any clear documentation to give me a answer. I'm running mod_perl 2 on RedHat with Apache 2.0.44 and I'm using NamedBased Virtual Hosting in apache (so I have a number of virtual hosts and apache directs properly based on hostname). I use a startup.pl to load up common things like DBI, CGI, HTML::Template etc.. Should I have just a single startup.pl and will that work with all virtual hosts? Or should I have a startup.pl per virtual host. Currently I'm using a startup.pl per virtual host and I'm seeing some strange problems, I'm wondering if my problem is there should only be one startup.pl - or does it not matter either way? Thanks -Chris

AFAIK, and with mod_perl 1.x, having multiple startup.pl's makes
no sense as
they all get executed during server startup and in the main namespace.

RE: Using a Startup.pl
Thanks for the explanation and the details Stas, I'm actually OK with everything in my startup.pl being available to all virtual hosts. After reading the post from Thomas I went back in and removed all the perlModule and perlRequire lines from the virtual host containers and loaded everything at once outside of the VHosts and it seems to have corrected my problems. Its good to know if there is a need to divide it the ability is there to do so (looks like I was doing it but without creating a new parent interpreter). I am using mod_perl 1.99.08, this is my second dev server and I've found that RH is OK as a OS but I've had MUCH better results leaving it at that and installing Apache, mod_perl and mySql etc. from source and not as part of the RH install or using RPMs.. Congrads to all you guys on mod_perl, I've heard about it and things like fastCGI for what seems like forever but until we got to the point where we were getting 1.8 million hits a day and everything was crawling as it was 99% perl, I never took the time to get into it - after the 300% performance increase seen after converting the entire site I simply cannot live without it and I refuse to do even the smallest projects using anything else. -Chris -Original Message- From: Stas Bekman [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 18, 2003 5:34 PM To: Thomas Klausner Cc: Modperl Subject: Re: Using a Startup.pl Thomas Klausner wrote: Hi!

That's correct only for mod_perl 1.0. For mod_perl 2.0 this depends on whether 'PerlOptions +Parent' is set or not. If it is each vhost can have their own startup.pl (only that vhost will ever execute/see the code that run from it). It's documented here: http://perl.apache.org/docs/2.0/user/config/config.html#C_Parent_ (though as someone reported PerlOptions +Parent doesn't work inside the Location container, I haven't had a chance to work on it yet.) However this is all new code and not very tested yet, so I won't be surprised if there are problems with it.

RE: Apache is exiting....
Hey Paolo,
Did you try to add some die statements to see if it made any difference, so
something like:
use Image::Magick;
my $image=Image::Magick-new(size='75x75');
$image-Read('null:white');
die display_error(Read Error Error: Image: null:white $image \n) if
($image);
my @x = $image-QueryFontMetrics
font='@/usr/X11R6/lib/X11/fonts/ttf/Ritalin.ttf',text='X', pointsize=12);
die display_error(ImFont Query Error: @x $image) if ($image);
Works for me, then I just have a sub called display_error that prints the
message and error out in a browser, but you could make that anything you
want.

When I load one of my webpages the browser never stops loading, e.g. the page loads ok and I can see and interact with it, but the ie spinning globe still keeps spinning and the status bar at the bottom of the page still shows the page is loading something.. The process does seem to run and exit normally in my logs. I'm at a loss as to what is causing it. This only happens on one specific page on my server. Any ideas would be appreciated.

RE: mod_perl 2 apache::session and or die
Thanks Perrin, I've been trying to use Apache::DB to track down the problem, but I'm not having a lot of luck. I think it is in the locking as if I let things hang long enough and then shut down Apache, I get a error of: Can't call method disconnect on an undefined value at /usr/lib/perl5/site_perl/5.6.1/Apache/Session/Lock/MySQL.pm line 89 during global destruction.

mod_perl 2 apache::session and or die
I'm having a problem since installing Apache::Session All works well except when there is any kind of problem in the script where the condition will die.. For example: $db-execute() or die... open yadda or die.. $db-prepare() or die... etc. When this happens everything to do with that script is unresponsive - I know that is a little vague but that is the best way I can describe it. What happens is the error comes up (standard server error) and that is the last thing that is logged, if you try to go back and refresh the hourglass will go for hours and nothing happens and nothing is ever logged - if you close all windows and try again then the same thing just happens, it goes forever and nothing happens or is logged. It doesn't seem to matter where the die is, if I'm using another module (for example) HTML::Template and it dies on bad params because I didn't define something some temple var then that is it.. I can't get to that script again until I reload Apache. This only happens when I'm using Apache::Session::MySQL and I'm not doing anything strange with it, I grab the cookie if its there and authenticate them. There is nothing I'm doing in the session that relates to the errors so I don't understand why everything just dies as it does. This happens on my RH7.3/1.3 install and on my RH8/2.0 install. One other thing I should mention, when this happens it only kills the script in that specific location that is defined in the httpd.conf, in otherword something running in /cgi-bin1/ has died and crashed, I can't get to it or do anything with it - during this time everything running in /cgi-bin2/ is running along just fine without a issue (although what is in /cgi-bin2/ isn't using Apache::Session but it is using the same mySql DB). Any ideas? Thanks -Chris

[mp2.0] Input Filter virus scan
Hi, newbie here, Can someone please tell me if the All-in-One Filter example located at; http://perl.apache.org/docs/2.0/user/handlers/filters.html#All_in_One_Filter can be used by a Anti Virus scan program to clear or block incoming Apache request data streams. Chris... [EMAIL PROTECTED]
[mp2.0] Input Filter virus scan (more info)
Me again, I have been asked to supply more details of what I am trying to achieve with the Input Filter. The following is an attempt to clearly define more requirements. I have an Apache/2.0.43 + mod_perl/1.99_08-dev + Perl/5.8.0 server that hosts simple static html and dynamic perl generated pages. I am unable to modify perl scripts without voiding my warranty. I therefore require a PerlInputFilterHandler to process the Apache request object and then pass it onto the default handler. The PerlInputFilterHandler is to scan the request object with an Anti Virus program (such as Sophos).

Randy, Thanks for putting up your repository. Two things: 1) DBD-mysql seems to have a dependancy on Data::Dumper, but Data::Dumper isn't found in any of the repositories so won't install properly. 2) Do you have any plans on building mod_perl 1.27 for the Activestate 8xx series? -Chris
Re: [Win32] ActivePerl-5.8 beta released
I asked Jan Dubois at ActiveState about this, just to verify - the relevant excerpt of his reply follows ... Luckily I'm on both lists (or at least I got a copy of Jan Dubois reply as well). Thank you for this. Perhaps related to this, was this build compiled with VC++ 6? Yes. For various reasons, we decided to continue to build ActivePerl with VC++ 6 SP3. I'm pretty sure that later service packs should be compatible too as the core Perl code doesn't use C++ anymore (the PERL_OBJECT stuff contained pointers to member functions, which changed size in VC++ 6 SP4 and later). I've also (just for testing) compiled extension DLLs for ActivePerl 633 and 802 using the free, non-optimizing VC++ 7 compiler from the .NET Framework SDK. It worked just fine, but it will use MSVCR70 instead of MSVCRT for the runtime library, resulting in 2 different C runtime libraries being loaded. This is potentially a problem with structured exception handling for C++, but should work fine for normal C extension code too. From this and other comments, I gather having two runtime libraries is a Not-So-Good-Thing (tm) I will probably breakdown and add VC++ 6 to my collection of toys. I'm far from an adaquate C programmer. Thank you for all your work supporting us red-headed step children in the Windows world. -Chris
Re: [Win32] ActivePerl-5.8 beta released
Of relevance to mod_perl-2 Win32 users, ActivePerl just released a beta version of their perl-5.8 binary; see http://www.activestate.com/Products/ActivePerl/ Because of binary incompatibilities with 5.6, there's a separate 5.8 repository of ppm packages under http://www.activestate.com/ppmpackages/5.8-windows/ Such packages should be compatible with the perl-5.8 win32 binary we have under ftp://theoryx5.uwinnipeg.ca/pub/other/perl-5.8-win32-bin.tar.gz if you've been using that. Even though the ActivePerl package is beta, they've tested it out beforehand and fixed some things compared to the CPAN perl-5.8 sources; see ftp://ftp.activestate.com/ActivePerl/src/5.8/ for the diffs and for the complete sources used. If you're using mod_perl-2 on Win32 with perl-5.6.1 and have run into problems (such as hanging registry scripts), you may want to try perl-5.8. Over the next few days I'll make up a 5.8 Win32 ppm repository with mod_perl-2 and some other common packages; I'll post something later with the details. Unless there's a large demand for mod_perl-1 stuff, this repository will just include mod_perl-2 packages. -- best regards, randy kobes -Chris

If you believe this to be true, then am I right in assuming that Activestate didn't manage to build the 5.8 beta with VC++ 7? I'd heard rumors that there was an attempt to build a version of Perl using VC++ 7 because Microsoft has a free non-optimizing VC++ compiler they ship with the .NET SDK. I was very excited by this prospect. ::sigh:: -Chris
RE: use http-equiv to refresh the page
I just wanted to mention that the meta tag as well as its http-equiv attribute are both official parts of the HTML standard and have been for quite some time. Yes and no. Well, I disagree with the no. I will explain it again below. HTML 4.0 has a section on META and http-requiv. In it, it mentions that \Some user agents support the use of META to refresh the current page after a specified number of seconds, with the option of replacing it by a different URI.\ and proceeds with an example. That sounds more advisory than part of the standard. But for the sake of argument, let\'s say it\'s part of the standard, and check what HTML 4.01 has to say. HTML 4.01 also has a section on META and http-requiv. However, the only reference to \refresh\ is: \Note. Some user agents support the use of META to refresh the current page after a specified number of seconds, with the option of replacing it by a different URI. Authors should __not__ use this technique to forward users to different pages, as this makes the page inaccessible to some users. Instead, automatic page forwarding should be done using server-side redirects.\ I\'m guessing this is because http-equiv is designed to hold an HTTP header, but there is no such thing as an \Refresh\ header in HTTP. No, there is an HTTP header called Refresh, and it is standard. The meta tag and the http-equiv attribute of the meta tag are also standard. However, some people seem to be confusing HTTP and HTML here for some reason. Refresh is an HTTP standard, while the meta tag is HTML. The http-equiv attribute of the meta tag allows some HTTP headers to be specified in the HTML. While this feature offers little to mod_perl developers who can manipulate the headers themselves anyway, it was historically very helpful to developers for providing accurate HTTP headers such as Expires when they could not otherwise do this. The reason for that warning in the HTML specification is due to what the W3C likely considers a rampant abuse of the Refresh header which was not intended for redirection but only for refreshing the current resource. They are not warning against Refresh alone but rather what they consider a misuse of Refresh. The key phrase is, \with the option of replacing it by a different URI.\ This is what is frowned upon, not the meta HTML tag nor the Refresh HTTP header. So http-equiv=\refresh\ is no longer standard. Of course, this is all theoretical. In practice, too many people are not easily swayed by a measily thing such as a standard. Right, and this was my second point in an earlier message. Support for this rogue feature is pretty widespread, though it should not be completely trusted. As one of the other posters pointed out, there are Web clients that do not support the use of a meta tag for redirection, but many (possibly most) do. It is quite common to see the use of a meta tag for redirection accompanied by instructions on the screen and a link for users that are not automatically redirected. By accomodating the users who are not automatically redirected, you can eliminate the possibility of a dead-end. Of course, I hope that mod_perl developers always choose manipulating the real HTTP headers over the use of the http-equiv attribute of the meta tag. Also, it seems possible that there might be much wider support for redirection with the real Refresh HTTP header than for the meta tag equivalent. I know of at least one attempt to test and document support for this specific use: http://www.hixie.ch/tests/evil/mixed/refresh1.http.html Perhaps the results of this test can help a developer determine whether this misuse of the Refresh header is appropriate for a certain situation. Chris
Re: use http-equiv to refresh the page
Is using meta tag a \bad\ approach? Yes. It\'s something that Netscape added to their browser, which others may or may not add to their browsers. It\'s not part of any HTTP spec and isn\'t guaranteed to work, even on totally correct web browsers. A meta tag is not something unique to Netscape nor the least bit uncommon. It is supported by all major Web browsers and has been for quite some time. While its use may be discouraged over a protocol-level redirect at times, it is appropriate for some situations and appears to be appropriate for what the original poster is trying to accomplish. As with any other HTML tag, the meta tag does not need to be part of an HTTP specification in order to be valid. Also, it is guaranteed to work on any compliant Web browser. HTML has its own specification, and the latest version describes the meta tag here: http://www.w3.org/TR/html4/struct/global.html#h-7.4.4.2 Sorry for disagreeing like this, but I am always afraid to see people being given incorrect information that might cause them difficulty. I hope this helps clarify. Chris

It's fine if there's a reason for it, but usually people do it because they don't realize they can just send a real header instead.. No, I actually agree with you completely on that last bit and am of the opinion that using the http-equiv attribute is a leftover habit from the early days of Web development when manipulating HTTP headers was not as convenient as it is now. I just wanted to mention that the meta tag as well as its http-equiv attribute are both official parts of the HTML standard and have been for quite some time. Netscape also introduced things like cookies and SSL, but that should in no way discredit the technology. The W3C's stance on refresh is the same for the header as well as the meta tag: they did not originally intend for it to be used to specify a *different* URL as a rudimentary method of redirection. They meant it to be used to refresh the current resource only. However, this rogue practice of redirection is quite common with both the header and the meta tag and is very well supported by browsers. In fact, I am not aware of any Web client that supports refresh but also limits the URL to the current resource only. It is also the only option for the pause, then redirect behavior the original poster desired that I can think of. Chris

a)What is the reason for this behaviour ? Why does
printing a message halt the redirection ?
b)What needs to be done to display a message saying
Redirecting .. and then the browser to auto-display
the new URL ?
a. When your script outputs something (sending a message as you say),
you are telling Apache that you are finished sending the HTTP headers
and have begun the content part of the response. Thus, it is too late
for the Location header you later want to send. This is a protocol
restriction based on the construction of an HTTP message. To avoid this,
you have to either send all of your HTTP headers first (my preference),
or you need to buffer your output until you are finished sending your
headers.
b. It sounds like you are wanting the user to visit an intermediate page
displaying a Redirecting ... message before being forwarded to a final
destination. In this case, you probably want to use HTTP's Refresh
header or the HTML equivalent: meta http-equiv=refresh value=???.
Both have the same syntax:
3; url=http://example.org/
In this example, the 3 is the number of seconds you want the client to
wait prior to sending the next request, which will be for the URL
http://example.org/.

Re: Filehandles
Personally I would suspect Windows in this case. I don't know about XP, but Windows 95/98/ME did not have a working flock. If XP is based on the NT code, it may not have that problem. Even so, I would try testing that first, or maybe asking about it on Win32 perl mailing list. XP is based on the NT Kernel, and should have a working flock. I believe In recent versions of 5.6.1 flock() is emulated on the 9x kernel as well. However this doesn't mean mod_perl supports it, but I'm pretty sure (98%?) Activestate and Win32 perl does. I've never flock-ed in my life (never had a need) but I have been tracking Perl and Apache under Win32 for quite a while so take all this with a grain of salt. -Chris

[ANNOUNCE] OpenInteract 1.50 released
A new version (1.50) of OpenInteract has been released to CPAN. OpenInteract is an extensible web application server built on Apache, mod_perl, the Template Toolkit and SPOPS object persistence. This version changes how templates are handled -- they're no longer accessible from the database. Browser-based template editing is back, however, and you can edit templates without having them overwritten with package upgrades. Documentation got a minor (but needed) overhaul. Thanks to Ben Avery for help.

Cache::Cache issues
Hi,
I've got a bit of an issue with Cache::Cache, and while I know it's a bit
off topic my e-mail to the module maintianer has dissapeared into the
nether regions of nowhere. I know that alot of people here use the module,
especially since it was the cookbook and Perrin's articles that put me onto
the module in the first place.
I can't seem to get the time-out on Cache objects to update, I'm not sure
if it's a bug in Cache::Cache or a bug in my understanding of Cache:Cache's
Cache::Object (much more likely).
I've written a small test script below that show's the issue I'm having.
Any clue's would be helpful.
package TestExpiresAt;
use strict;
use Cache::MemoryCache;
our $Cache = Cache::MemoryCache-new({
'namespace'=__PACKAGE__,
'default_expires_in' = 10,
});
$Cache-set('1', 'Yes', 1800);
$Cache-set('2', 'no');
my $timeout1 = $Cache-get_object('1')-get_expires_at();
my $timeout2 = $Cache-get_object('1')-get_expires_at();
print $timeout1\n; # this should be timeout2 + 1790
print $timeout2\n; # but it's not even different
$Cache-get_object('1')-set_expires_at(10 m);
$timeout1 = $Cache-get_object('1')-get_expires_at();
print $timeout1\n; # should be different again from timeout1 above
print $timeout2\n; # and from timeout 2
1;
__END__

Distinct content handlers each with their own Location directive. Could be a pain to maintain the server config. 3. Take a small performance hit and use an Apache::Registry script for each screen to handle the content phase. Use 'PerlSetupEnv Off', $r and Apache:: modules and don't bother being backwardly compatible with CGI. There's a separate one that's used in OpenInteract: create a single content handler that uses some sort of lookup table to map requests to handlers. This lookup table can be maintained separately from the apache configuration and can generally be more flexible, allowing for application-level security settings, etc. Chris -- Chris Winters ([EMAIL PROTECTED]) Building enterprise-capable snack solutions since 1988.
OpenInteract 1.41 released
A new version (1.41) of OpenInteract has been released to CPAN. OpenInteract is an extensible web application server built on Apache, mod_perl, the Template Toolkit and SPOPS object persistence. This is a fairly minor upgrade -- a few bugfixes and refactorings, plus the ability to use a centralized repository for your custom templates so they will not get overwritten with package upgrades. As always, the other modifications in this release are listed in the 'Changes' file.

Re: Apache::DProf

Re: Apache-print Timed Out
This may be a long shot but the circumstances sound familiar. I had a problem where an HTTP connection was simply not being properly closed and Netscape4 was just hanging around waiting for the response to finish whereas other browsers/platforms had no problem, ie. the other browsers were auto-cancelling the delayed response. Connecting to port 80 over telnet also clearly showed the connection was simply not closing and I modified the java proxy server source in an attempt to hammer blow the connection. Turns out that the JRE needed upgrading on the proxy and the I/O worked properly. My point is it may well be nothing at all to do with Apache/mod_perl. I had been trying to debug the PHP engine on the server but telnetting from the proxy to the server showed the connection was closing correctly so it had to be the proxy's fault. as I said, this may be a long shot. chris On Thursday 18 Jul 2002 3:21 pm, you wrote: On 7/10/02 10:37 AM, David Wheeler [EMAIL PROTECTED] claimed: I have a couple of strange bugs showing up in Bricolage that have something to do with Apache-print timing out (with Win 95 and Mac OS 9 -- yes, these folks need to join the new millennium), and have no idea how or under what circumstances print times out. Okay, I've got the output of some tcpdump runs in Bricolage Bugzilla. http://bricolage-bugzilla.thepirtgroup.com/showattachment.cgi?attach_id=35 All they demonstrate, however, is that Apache/mod_perl never finishes sending the page to the browser. One page is 32120 bytes, and the other is 36500 bytes. I really have no clue what could be causing this. Why should Apache-print ever time out?

Weird problem with cookies on Netscape with apache running a virtualhost
This might be a little off topic. I recently installed apache 1.3.26 with modperl 1.26. I run a virtual host seconady website. When I try to retieve or write cookies to a netscape browser from the virtualhost URL it doesn't work. cookies work fine on the main server. cookies work fine on both main and virtualhost using an IE browser. This all worked fine on both before I upgraded apache and modperl. I use Apache::Vookie to set and retrieve cookies. Anybody have an Idea to point me in the right direction to solve this? Thanks, Chris

Chris,
It is a bit difficult to determine your problem but here are a few
suggestions:
1) Revert to $r-headers_out-set('Set-Cookie',
cookie(-name='cookie_name', -value='value_here')); If this works, check
for a difference in the module you are using.
This works but I need to set multiple cookies. Im doing this:
my $c = new CGI::Cookie(-name = 'SID', -value = 'stuff', -expires
= '+6M');
my $cc = new CGI::Cookie(-name = 'BUD', -value =
'Wassup', -expires = '+6M');
$r-headers_out-set('Set-Cookie',$cc);
$r-headers_out-set('Set-Cookie',$c);
$r-cgi_header_out('Location',mypage.html);
$r-send_http_header;
This only sets one of the cookies ($c). How do I set multiple cookies?
CGI::Cookie says to concatenate using a ; but that errors out.
Sorry, bit of a novice here.

i didn't get a chance to try it, but it should be easy to try.
$r-cgi_header_out('Location',mypage.html);

Re: [OT] Better Linux server platform: Redhat or SuSe?
From: Barry Hoggard [EMAIL PROTECTED] Date: Wed, 03 Jul 2002 11:52:21 -0400 Remote maintability: Is it possible to remotely upgrade between OS versions for either of those platforms (not a must, but would be a plus)? I would be afraid to do that remotely, since it normally involved a kernel change as well. We have an internal distribution which is kinda mostly a redhat system gets various RPMs updated remotely including kernel RPMs, but I'm *very* careful with kernel RPMs and do multiple installs on non-remote systems before I do any remote systems. Sendmail: Does the system make it easy to replace sendmail with another mailer of choice (qmail in my case)? I don't know about Red Hat, but it's certainly easy in SuSE. Build your own RPM from one of the SRPMs out there and qmail will work fine. Footprint: Is it easy to weed out unused system components to have a smaller footprint of the OS? Or does that mean fighting the installer left and right? I don't know if Red Hat is getting any better, but I've always found it difficult to do a minimal install. SuSE has options for a very minimal install which is what I use for server installs. We created our own comps file for our custom configs. perl: Any iussues with perl/modperl? Besides modperl I will be running a perl application with a few hundred thousend lines of code... My current project: http://www.better-investing.org runs on Red Hat. I'm not aware of any perl/mod_perl issues, but I built perl and the apache binaries myself. I don't use their RPMs. I use a mix of RedHat RPMS, my own RPMs and other people's RPMs. My perl and apache RPMs are all currently from Mandrake. (I seem to be gradually migrating towards Mandrake.)

On Mon, 2002-06-10 at 13:29, Ray Zimmerman wrote:
So how is everybody else handling URL mapping? Do others group this
kind of data together with fonts, colors, etc? And where do you
define it?
As Perrin mentioned, OpenInteract does this by allowing individual
packages (distributable applications) to define the handlers they
support. A package does this by defining actions which at server startup
get collected into a data structure called the action table.
A single mod_perl handler catches all requests, looks up the URL in the
action table and dispatches the request to the appropriate handler. That
handler is free to pass on the request to other actions as well, since
every part of the system is able to lookup actions based on a key.
Entries in the action table can also be used as components --
displayable items that don't stand by themselves but contribute to a
full page. Examples include boxes, common search forms, dependent object
listings, etc.
Currently, here's what an action looks like, as found in the 'base_user'
package distibuted with OpenInteract:
$action = {
'user'= {
'class'= 'OpenInteract::Handler::User',
'security' = 'no',
},
'newuser' = {
'class'= 'OpenInteract::Handler::NewUser',
'error'= [ 'OpenInteract::Error::User' ],
'security' = 'no',
},
};
All information is available through a lookup to the action table.
One of the modifications I'm working on now will allow you to add more
information to the action and have it available in an object that is
instantiated by the dispatcher which then tells the object to run
itself.

Re: separating C from V in MVC
::really hesitates to step into this ... but like a train wreck ... he simply can't resist:: It's like asking why XML has different syntax and semantics from Perl. Well, if you read the XSLT spec and then look at an XSLT program, you'll see a lot of verbosity and a lot of general purpose constructs like variables, conditionals, and loops. I haven't done much with XSLT, but I do know you can get it in an infinite loop. That seems pretty general purpose to me. Well aside from the fact that XSLT is Turing complete (And thus theoretically as powerful as Perl or C or Java) the syntax structure of XSLT (because it is a derivitive of XML) makes it difficult to do some things (try writing a version of sed in XSLT). This I think was the original point. Perl handels Regex's better than C, this is one of the reasons people use Perl. It makes (some) hard things easy and (some) impossible things hard ... within it's domain. XSLT is no different. Use the appropriate tool (or Toolkit) for the problem. I think the rule is: if you can solve Towers of Hanoi in the language, its general purpose enough. True formatting languages, such as, Scribe do not contain general-purpose constructs, so you couldn't solve the Towers of Hanoi. HTML is another good example (ignoring script). I do want to point out for clarity and posterity that HTML and XSLT are siblings ... in that they are both applications of XML (or SGML). HTML is not Turing Complete while XSLT. Turing completeness has a mathmatic existance beyond the Towers of Hanoi problem. But I haven't seen it solved in TeX either (::know's there's gotta be a link for this::). Rob, is what you are suggesting that one should not use a turing complete language for visual markup or that simply the language should be the best match for the solution? I'm just looking for clarity on your position. Why is there so little discussion of the M in MVC? It's far from a trivial problem. As I am currently mostly writing M and C and would be interested in some thoughts on the issues surrounding M. Like what issues have other people come across and how have other's dealt with them? This is the biggest benefit I have gained thus far from Perrin's eToys article (that and using it to sell mod_perl to my superiors as a better solution than Java eToys delt with 10x these many customers ... I think our system can handle the load). -Chris -- [A] Genuinely skillful use of obscenities is uniformly absent on the Internet. -Karl Kleinpaste
