Re: 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. Not that I know of, but yes LWP should be a good solution. And I would be interested in collaborating on testing this tool, if you choose to work on it! BTW, for client side based benchmarks see: http://perl.apache.org/guide/performance.html#Tuning_the_Apache_s_configuratio 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.

What I'm worried/thinking about is layout disparity. I think that information pertaining to jobs or success stories needs to be present on the mod_perl site. It would feel awkward to jump to another site for that, even when both layouts are good if they are (too) different it looks messy. So if that information is meaningful within modperl.sourcegarden.org and within perl.apache.org, mirroring the info in a database daily (or using one source) really doesn't sound like a dreadful technical challenge to me. But I must add to that that there is something within me that wishes to speak against duplication, even if it doesn't become a technical nightmare. However, it can't seem to find arguments to support itself. I am totally open to discussion on this point. Anyway, let's stop talking about "you" and "we", we are all "we" :) No competition, only collaboration. You'd expect competition to have crossed my mind and be rejected, but it actually hasn't. I am very happy to learn that part of the job has been / is being done. I think one important thing would be to decide what goes into modperl.sourcegarden.org, what goes into perl.apache.org and perhaps what goes into both. Duplicating efforts would be of course stupid, and drawing the line between site that intertwine and sites that truly overlap can only help.

But you should understand my motives for moving to modperl.sourcegarden.org. Otherwise there was no reason not do everything at perl.apache.org. So, perl.apache.org is just a VH at apache.org. You have almost no ability to add components to the system, and of course no root access. Installing mod_perl, mysql, modules is absolutely possible technically, but in reality it isn't, because no matter whether you have a root access or not, the resources are limited... I guess other resources to... With SourceGarden I've everything I want and need, thanks to Scream Design team folks! That's why I feel much better creating for this site, and I cannot tell myself, I don't feel like adding this feature, since it's a headache to ask permission to do that and chances that the it would be approved... So we (the folks behind SourceGarden) have no excuses not to do something, so we do it... I'm not sure whether you have thought about the described limitations as part of your plan. But if you come up with solution that will allows us to run mod_perl and mysql at perl.apache.org - I think we would be delighted to have James' tool running on perl.apache.org, so you wouldn't jump between sites... For me as of this moment perl.apache.org is a gopher site (remember that name?), with links for downloading docs and mod_perl. And that's not far from truth. If we succeed to revive perl.apache.org to make it a dynamic site, I don't see any reason to have all the functionality we wanted to add to SourceGarden there.

RegistryLoader causes subroutine redefined errors on import?
I know this topic has been discussed to death, but I think I can add
something new. :-)
Upon using Apache::RegistryLoader, I noticed my error logs started
filling up with the dreaded "subroutine redefined" error. These errors
occur at the moment my scripts scripts are preloaded using
Apache::RegistryLoader.
I put together a minimalistic example to demonstrate the problem.
Consider the following module where function "foo" is exported by
default and "bar" is exported on request.
###
package Foo;
use strict;
use vars qw(@ISA @EXPORT @EXPORT_OK);
use Exporter ();
@ISA = ('Exporter');
@EXPORT = qw(foo);
@EXPORT_OK = qw(bar);
sub foo {
return "foo";
}
sub bar {
return "bar";
}
1;
###
And consider the following script served by Apache::Registry:
###
#!/usr/bin/perl -w
use strict;
use CGI ();
use Foo (); # works okay, no error
#use Foo; # causes "Subroutine foo redefined..." error
#use Foo qw(bar); # causes "Subroutine bar redefined..." error
#use Foo qw(:DEFAULT bar); # causes errors for both foo and bar
my $q = CGI-new();
print $q-header();
print "Hello World\n";
###
I tried the above script while "use"-ing Foo using the above techniques
(stopping and starting the server each time to retest
Apache::RegistryLoader.) Upon each server start, RegistryLoader kicked
out the error(s) shown commented above. So it seems to be the import
process causing the error.
In all cases, the Apache::Registry script works fine. The error only
appears when the script is preloaded using Apache::RegistryLoader -- I
can suppress the error by not using RegistryLoader.
So what's causing the error? Why is the subroutine being redefined?
Thanks,
Matt

RE: Embperl and Apache LogLevel configuration
Here's the portion of my httpd.conf that deals with Embperl: That's ok. I think I found the reason: [3396892]ERR: 30: Line 1: Not found /usr/lund/wwwfiles/wnetdoc/map.c.html As always there is an expection to the rule. The "Not found" (and FORBIDDEN) errors are not going thru the Apache ap_log_error function, because Embperl checks these things before it has setup it's internal data structures. So all error messages are affected by the LogLevel (and get a timestamp) except these two. These two errors are always printed to stderr. I try to corrected this in the next release. By the way, even though I "SetEnv EMBPERL_LOG /dev/null", /tmp/embperl.log still is written to. I had to set that file to be a symlink to /dev/null. Yes, that isn't surprising. The docs about EMBPERL_LOG says: NOTE: When running under mod_perl you need to use PerlSetEnv for setting the logfile path, and mod_perl = 1.07_03 if you load Embperl at server startup (with PerlScript or PerlModule). So use PerlSetEnv instead of SetEnv, because the values set with SetEnv are not available at server startup time. BTW Setting EMBPERL_DEBUG to 0 should supress any output to the Embperl logfile.

Apache::Session hangs script

subsequent calls to the script, and use it to re-open the session object
as described in the Apache::Session doc.
1 or 2 calls _after_ the intial invocation of the script, my browser
hangs. Using the debugger, I've found where it seems to get hung up --
see below.
Is this some sort of lock blocking, or stale lock or something? Any

Re: Apache::ASP - accessing Session data from Application
Thanks, Joshua. I tested out your development version 0.17 and it worked perfect for me. One thing I noticed was that if GetSession is improperly used, it could cause big security holes. By nature it will be used to access someone else's session, so the application should take care not to send the other SessionID across the net. Even within an SSL connection (as I'm using) it's not wise to even let one other person know the SessionID of another user. I made an internal 1:1 reference map of SessionIDs to unique identifiers which then can be sent over the net safely, to allow controlled access to other sessions. Anyway, just thought I'd mention this, though I'm sure you already realized it. You might want to put a note in your API documentation to take care not to reveal the SessionID when you use GetSession. - Adi Joshua Chamas wrote: I have added an $Application-GetSession($session_id) API extension to Apache::ASP.

Porting to Apache::Registry
I'm just starting in on porting some scripts over to either Apache::Registry or Apache::PerlRun, and trying to absorb as much as I can. It's seems a bit overwhelming at first. My scripts are reasonably clean, running under -w and use strict, yet I'm sure I have lots of porting issues to deal with. I understand that it's hard to answer without knowing details about my setup, but in general are the speed gains with Apahce::Registry over Apache::PerlRun worth the extra porting work? Besides all the information at perl.apache.org, can you recommend any good resources (book, web pages) that stand out in your memory as being very helpful when you were starting out? I have a bunch of questions, of course, such as: Under Apache::Registry do I have to be aware of other Apache::Registry scripts that may be running under the same server process as my program? For example, I often open STDERR to a log file in my CGI scripts. Will all scripts running on that process then write to my log file? And I often have a public CGI script, and an 'Admin' script where the public script opens a log file (using STDERR) with a share lock, but the 'Admin' script opens with an exclusive lock on the same file when updating config files. It would seem to make sense to not have to open and close the log file for each execution, but rather leave the file open and just grab and release the lock during execution.But I'm really unclear how to set this up under Apache::Registry and if there are race conditions to worry about. Anyway, I'm really seeking pointers on good references for just starting out that will help me answer these type of questions and keep me quite for a while.

Re: Apache::ASP - accessing Session data from Application
Yeah, I'd be happy to. I'm not quite done with my app-specific version, but once I get done I'll genericize it and send it along. I'll have to write up some documentation, too. It'll probably be a week or two before I have something worthy of publication. - Adi Joshua Chamas wrote: About your session manager, I have been thinking about starting up some sample applications repository for PerlScript ASP applications, which could be easily distributed with Apache::ASP. Would you be interested in publishing some genericized version of your session manager? It seems like a cool app. -- Joshua _ Joshua Chamas Chamas Enterprises Inc.
