Of course it does matter not to have the stuff duplicated, since it's a nightmare to keep 2 things in sync, but why should we doing that? I don't see any reason... We wanted to do that to complement the current site, if you are going to do that anyway, there is no reason, why we wouldn't put our efforts to create other useful things...

James is working on this application, which is in pretty good stage (James?), why in the world would you want to write something else from scratch? James' tool will be able to index jobs, ISPs, application, modules whatever... So I think that the best idea would be to join James, and in a joint effort deliver it sooner, influencing on the way the final set of features...

load/regression test builders, monitoring tools for mod_perl apps
Does anyone know of any good open source test builders for regression/performance-testing a mod_perl app? This is the essence of what I would want such a suite to do: RECORD: -set up a proxy server to forward HTTP requests to a mod_perl'd server. -capture all GET/POST requests from the client and log them to a file, along with the server's output. The server's output would be the 'master' copy. PLAYBACK (REGRESSION): -play back the GET/POST requests and capture the output. Compare the output against the master copy. Raise an error in the log file if the two differ. PLAYBACK (LOAD): -play back the GET/POST requests according to some load scheme to see how well the application holds up under load. If this doesn't exist, I think it would be easy enough to write using LWP; I just don't want to duplicate anyone's efforts. I'd also be interested to know if anyone knows of any good webserver monitoring programs that could automatically kill spinning httpds, short of a CRON job. FYI-- I have encountered mystery spinning httpd's as well, but I have always been able to pin it down on bad/risk code or thrashing. At any rate, I still need to be able to kill spinning httpds should it come to that. cheers, Ed

mod_perl with APXS plus Raven equals segfault
I've been using mod_perl with Raven's SSL package for some time now, but I'm building a refresh of our environment with new versions of everything and I ran into trouble. I decided to use APXS this time instead of building mod_perl statically. Everything compiled and installed fine but Apache immediately segfaults on startup. The details: Sun Ultra Enterprise 3500 Solaris 7 (HW 5/99) Apache 1.3.9 (built from Raven pre-patched source) Raven SSL 1.4.1 mod_perl 1.21 perl 5.005_03 gcc 2.95.1 (regular Solaris ld, GNU ld is not even on the system) I guess I can go back to compiling mod_perl statically, but it would be nice to get this fixed.

Apache::ASP
Hi, I have to use Apache::ASP for a project of mine. The client wants to have a java applet which will send some information in an encrypted fashion to the ASP . The ASP will have to recieve this encrypted information and then send it to the apache server. I want to know if this is possible. What should I be doing to pass the information from the java applet to my ASP in a secure manner? Do i need to use HTTPS protocol ? Please help me. Regards, Devarajan __ Do You Yahoo!?

mod_perl/proxy setup -- ISP buffering?
Another question on the issue of slow (modem) connections and having a lightweight front-end to the mod_perl servers... A slow modem connection would typically exist between a client computer and an ISP; the ISP would have a fast network connection to the Internet. Are there any ISPs that do significant buffering of webserver responses for their slow clients? If so, wouldn't this reduce the advantage of doing the buffering within a server-side lightweight front-end to mod_perl? How often should I expect this behavior from ISPs? If ISPs don't do this kind of buffering, why not? Thanks, --Jonathan Marshall -- Jonathan A.

There are definite advantages to keep-alive from a tcp perspective since fresh connections will incur not only the 3 way-TCP handshake but also be penalised by slow-start. So while turning it off may help the memory usage on the server, it will disadvantage the client from a network speed perspective ... tricky. One option I suppose would be for the proxy/accelerator to keep the connection open to the client but make individual connections to the server, read the response, buffer it for sending to the client and close the server connection (making new connections to the server as required by the client requests obviously). Given the speed of the network connections I deal with, this may be a win but I'm only on day 3 of playing with mod_perl things so it's hard to tell ;) Cheers, --Craig
setting cookies?
System:
Solaris 2.6
Apache 1.3.9/mod_perl 1.19/gcc 2.8.1/perl-5.004.04
I'm using SecurID to authenticate for an Apache proxy server. I've
written a little perl module that uses a username/tokencode returned by
basic auth to validate a user and return a session cookie. The SecurID
auth works fine and I'm able to generate a cookie for the user.
The problem is, I can't get the module to return the cookie to the browser
before the proxy request is completed.
Initially, I tried:
[...SecurID auth...]
$r -> header_out('Set-Cookie' => $cookie);
return OK;
That didn't seem to work (no cookie in the snoops, Netscape has no
knowledge of it). So, I turned to sending back a redirect instead:
[...SecurID auth...]
my $req_uri = Apache::URI->parse($r, $r ->uri);
$r -> header_out('Location' => $req_uri);
$r -> header_out('Set-Cookie' => $cookie);
return REDIRECT;
Before any of this, I tried the TicketAccess example from the mod_perl
O'Reilly book but the circular nature of authenticating a proxy rendered
that unworkable.
My current solution is so close--I just need to get that cookie to the
browser and have it returned on each subsequent proxy request. What am I
doing wrong?
Thanks!

Well, I am writing a session monitor application, which monitors what's

on, but fix things for the user. As in the context of a user(newbie) and
administrator. I want the administrator to be able to physically fix the
things that the user has broken- in other words, have write access to
arbitrary user Sessions.
I suppose I could do it all through an Application->{SessionID} structure,
but then I wouldn't be using the Session object at all. And I do have some
locking going on, which would make this very unwise. There could be serious
bottleneck if everyone is just using Application, since Application->Lock
locks the whole shebang.

Re: Apache::ASP - accessing Session data from Application
Thanks for your help. I guess I was wondering if one could get a reference
to the $Session object directly without needing to add each value to
$Application as it is stored. So to access arbitrary Session data from
Application I need to store it in Application at the same time it's stored
in Session? e.g.
$Session->{'foo'} = "data";
$Application->{'Session'.$Session->{SessionID}} = { 'foo' => "data" };
Do you think there are any advantages to adding a "Get_Session" method to
$Application that will return a reference to the Session object with a given
ID? e.g.
my $sessobj = $Application->Get_Session("87c6039a20a50a01000a054b547add4b");
print $sessobj->{'foo'};
That way I wouldn't have to go through all my code adding Session data to
Application. :) How hard would implementing such a method be?
Yes, I'm using DB_File to store data, so the size won't be a problem. BTW,
are there still problems using Storable with DB_File?
Thanks again,

Check out the online demo at:
http://www.nodeworks.com/asp/eg/global_asa_demo.asp
or just site/eg/global_asa_demo.asp in the asp distribution
for an example of this kind of user tracking in $Application.
You end up having to add the information that you want
to $Application yourself, and cleaning that up in
Session_OnEnd.
Remember that if you are using SDBM_File databases
for $Application & $Session, default, you only have
1024 bytes to store the key and value, so you can't
store a lot of user data like:
$Application->{users} = \%users;
you have do do more like:
$Application->{user1} = name;
$Application->{user2} = name;
Or you could switch to DB_File for larger amounts
of data stored in one hash key.

wait, this happens at startup? you must have mod_perl configured as a
dso, notice in the ToDo file:
- USE_DSO=1 --> END blocks are run at startup time
END blocks are normally not supposed to run until child_exit.
could be something related to that, try linking static instead of dso,
does the problem go away?

For what it's worth, I've been experiencing the same situation. Happens less often, but that may be just because I have less trafic. Mind that W mode is 'sending reply' which is consistent with the module being hung. I haven't raised this issue on the list because I haven't been able to track it down and therefore I assume it's a bug in my code.

Hi, as I can see, my first letter didn't get any attention. I think such
"behavior" is very weird:
Lets consider two separate files, with different names:
first.html
[-$qstr="/trtickets/solvermodules/contract_ver2_refuse.html?$fdat{blaah}";-]
Blaah
[-$qstr="/trtickets/solvermodules/contract_ver2_pysi.html?$fdat{blaah}";-]
Blaah
second.html
[-$qstr="/trtickets/solvermodules/contract_ver2_refuse.html?$fdat{blaah}";-]
Blaah
[-$qstr="/trtickets/solvermodules/contract_ver2_uucp.html?$fdat{blaah}";-]
Blaah
when I load some times file first.html, I see every time source:
Blaah
Blaah
Thats ok.
and then, when i load file second.html, I excpect to see source:
Blaah
Blaah
but I get:
Blaah
Blaah
And I have tens of such effects.
Any ideas?

hanging processes
Hi. I have an apache server (1.3.6/Solaris 5.6) running mod_perl/1.21. For it, I have a fairly complex handler involving several classes, some of which bind to libraries (one of them is ImageMagick). The server is configured to only allow requests for this module, and does not serve any static pages. At least once a day, I will find an http process monopolizing one of the 4 CPU's in our production machine (E-450); server-status claims it's in W mode (waiting for connection) but the log that our module generates indicates it hangs at an arbitrary point within it's flow. We have poured over the code, and over the FAQ's, etc, at the mod_perl site, but have no ideas beyond a cron to kill these abhorrant processes when their cume CPU time exceeds some level (not a great measure...we had to set the threshold very high as to not kill happy processes). Can someone shed any light on what may be happening, or a better way to monitor and kill these children? Thanks, in advance. Marc Spencer www.kodak.com "0201: Keyboard Error.

RFC: new section: using RPM to install mod_perl + RPM itself!
Hi, all Geoffrey S Young and David Harris created both the RPM and documented the logic and possible pitfals with installing mod_perl from RPMs. Those of you that have asked for help regarding RPMs, would you please go thru the document and see whether it answers your woes, and of course the RPM itself. This is imporant to do it now, while things are hot. Take the chance while Geoffrey and David are ready to help and jump on it - try it send your comments. (I don't say they wouldn't in the future, you know how it works :) The moment you refine both the RPM and the document, others would have much easier times with installing mod_perl, becoming and active user, tester and even developer. So we are all to benefit from this movement (Please, no flames - RPM is bad, install from scratch -- there is no reason to scare away new potential users. Just remember that this RPM would be installed on millions PCs of RH and other Linux users! So it worth to take the effort and fine tune this section and the RPM.) Thank you! Either read the HTML version at: http://perl.apache.org/guide/install.html#using_RPM_DEB_and_other_package Or I'll reproduce it here in text: A word on mod_perl RPM packages The virtues of RPM packages is the subject of much debate among mod_perl users. While RPMs do take the pain away from package installation and maintenance for most applications, the nuances of mod_perl make RPMs somewhat less than ideal for those just getting started. The following help and advice is for those new to mod_perl, Apache, Linux, and RPMs. If you know what you are doing, this is probably old hat - contributing your past experiences is, as always, welcome by the community. [TOC] Getting Started If you are new to mod_perl and are using this Guide and the Eagle book to help you on your way, it is probably better to grab the latest Apache and mod_perl sources and compile the sources yourself. Not only will you find that this is less daunting than you suspect, but it will probably save you a few headaches down the line for several reasons. First, given the pace at which the open source community produces software, RPMs, especially those found on distribution CDs, are often several versions out of date. The most recent version will not only be more stable, but will likely incorporate some new functionality that you will eventually want to play with. It is also unlikely that the file system's layout of an RPM package will match what you see in either the Eagle book or this Guide. If you are new to mod_perl, Apache, or both, you will probably want to get familiar with file system used by the examples given here before trying something less standard. Finally, the RPMs found on a typical distribution CDs use mod_perl build with Apache's Dynamic Shared Objects (DSO) support. While mod_perl can be successfully used as a DSO module, it adds a layer of complexity that you may want to live without for now. All that being said, should you still feel that rolling your own mod_perl enabled Apache server is not likely, here are a few helpful hints... [TOC] Compiling RPM source files It is possible to compile the source files provided my RPM packages, but if you are using RPMs to ease mod_perl installation, that is not the way to do it. Both Apache and mod_perl RPMs are designed to be install-and-go. If you really want to compile mod_perl to your own specific needs, your best bet is to get the most recent sources from CPAN. [TOC] Mix and Match RPM and source It is probably not the best idea to use a self-compiled Apache with a mod_perl RPM (or vice versa). Sticking with one format or the other at first will result in fewer headaches and more hair. [TOC] Installing a single apache+mod_perl RPM If you use an apache+mod_perl RPM, chances are rpm -i or glint (GUI for RPM) will have you up and running immediately, no compilation necessary. If you encounter problems, try downloading from another mirror site or searching http://rpmfind.net/ for a different package - there are plenty out there to choose from. David Harris has started the efforts to build a better RPM/SRPM mod_perl packages. You will find them at: http://www.davideous.com/modperlrpm/distrib/ Features of this RPM: Installs mod_perl as an ``add in'' to the RedHat Apache package, but does not install mod_perl as a DSO and all the problems that brings. Includes the four header files required for building libapreq (Apache::Request) Distributes plain text forms of the pod documentation files that come with mod_perl.

How to disconnect persistent db connections when killing httpd
Hi,
I keep persistent db connections and would like to
explicitly disconnect db when killing httpd.
I have custom module where I initialize db connection, prepare sth's
( will use them in Mason components ) once for per children
and several methods which have deal with my database. Here I have
DESTROY method which supposed to disconnect all connections.
sub DESTROY {
my $self= shift;
$self->disconnect;
warn "Db connection finished $self ...\n";
}
$self->disconnect is a sub which finish all sth's and disconnects connection
with db. But I have nothing in error log when I kill httpd and I didn't
understand what's happens because if I comment call $self->disconnect
I see messages from DESTROY method foreach children:
Db connection finished My::DB=HASH(0x80cd240) ...
So, is't worth to try explicitly disconnect db when httpd gets killed
and how to do this using standard method like DESTROY without
catching signals and etc.
Another question:
If I keep persistent connection httpd <-> db and did some changes in
db, say dump/reload table. How to refresh existing dbh ?
Regards,
Oleg
I wrote script to emulate above. I expected warn message from DESTROY
method when script finished.
1. DESTROY is just warn
18:38[zeus]:~/app/discovery/test/bench/dbi>tt.pl
Db connection finished My::DB=HASH(0x80cd240) ...
2. DESTROY calls $self->disconnect and then warn
18:40[zeus]:~/app/discovery/test/bench/dbi>tt.pl
Nothing is there.
test script:
#!/usr/local/bin/perl
use strict;
use My::DBtest;
# use this connect string
$ENV{DBI_DSN} = "dbi:Pg(RaiseError=>1,AutoCommit=>0):dbname=discovery";
#DBI->trace(2);
my ($dbh, $count );
$dbh = My::DB->new(1);
# $dbh->disconnect;
--
Simplified version of module My/DBtest.pm
package My::DB;
$VERSION = 0.1;
use strict;
use DBI;
my %query = (
sth0 => 'select count(*) from messages',
);
my $self = {};
sub new {
my $proto = shift;
my $class = ref($proto) || $proto;
$self->{dbh} = DBI->connect() or die ("Connections fails; $!\n");
prepare_sth($self);

$self;
}
sub prepare_sth {
my $self = shift;

Here's the code:

my $cache = $dbh->FETCH('CachedKids');
$dbh->STORE('CachedKids', $cache = {}) unless $cache;

if !$allow_active && $sth->FETCH('Active');
return $sth;
}
$sth = $dbh->prepare($statement, $attr);
$cache->{$key} = $sth if $sth;
return $sth;

KeepAlive in mod_perl/proxy setup is evil...
[CC'ing this to modperl list, this is something of general interest and a good topic for an interesting thread] > Just reading through your excellent mod_perl guide and the section regarding > using accelerator/cache proxies made me think of the following question: > > What about HTTP/1.1 and keepalive connections?

This would mean that the proxy does not provide an advantage at > all. Correct? Idealy, one of the big advantages proxy provides for mod_perl is downsteam buffering. What happens is that mod_perl immediately generates the output, hadles it to proxy to return to a slow user, which immediately allows to close a connection. So the first question is how big your proxy buffer, since if mod_perl cannot send it all to proxy it doesn't really helps. You are talking about KeepAlive... Hmm, I think you are right, I should have mentioned this point. Do you think the KeepAlive should be turned off? Since there is no actually need for this option (all the static objects are being served by a lighter process). But if the KeepAlive is on, mod_perl will keep the connection open, till it timeouts or terminated. So it breaks all the "improvements" down :( If I'm not missing something, you've got a real case here. What do you think folks? This issue should be really benchmarked... since there is lots of theories but no numbers... Anyone has checked his ProxyBuffer size? How big can it be in squid and mod_proxy? I saw a few folks reporting about limitation of the buffer size. I really would like to have a better picture of this vague topic. Anyone can share his experince, and shed some details on this topic?

Apache::ASP - accessing Session data from Application
Is it possible to access data from an arbitrary $Session object from the
$Application object. For example, say for each Session opened, I store the
username in $Session->{'user'}. Can I get a list of all the users currently
connected to the server? What about arbitrary data currently stored in the
Session object?
In global.asa I have
sub Session_OnStart {
$Session->{'user'} = Apache->request->connection->user;
my %session;
if (ref $Application->{'Session'} eq "HASH") {
%session = %{$Application->{'Session'}};
}
$session{$Session->{'SessionID'}} = $Session;
$Application->{'Session'} = { %session };
}
sub Session_OnEnd {
delete $Application->{'Session'}->{'SessionID'};
}
But this only stores the Session hash as it is when the session starts. So
I only get the user data value. Any data that gets added to Session after
it starts doesn't show up in $Application->{'Session'}->{'SessionID'}
Is there a way to get a reference to a session object given the SessionID?
If not, is there any plans on adding that feature? If not, I'd be happy to
code in that functionality if no one's working on it.
