Translation handler continuous loop problem
I am hoping someone might have a clue on how to resolve this awkward problem. I have just installed a mod_perl URI translation handler to extract a session id from the URI. In general the translation works correctly by removing the session id from the URL when detected. However, a Netscape browser client triggers Apache to enter a continuous loop if I do not specify the domain name in the hostname component of the URL. The problem does not occur in Internet Explorer (that surprised me.) All these examples are from Nestcape on both NT and Unix. For example, say I enter http://lions.access.com/sp9/outage.html The translation handler works correctly. If I then enter: http://lions/sp9/outage.html There is a continuous loop in Apache and on each iteration, an entry is written to access_log. I have to stop the request in Netscape. The bizarre thing is I can enter any other URL such as http://lions/internal/whatever and there is no problem. The mod_perl translation header goal is stripping session id info from the URL in the form http://hostname/SESSION_ID/sp9/whatever It looks for sp9 in the path. I have attempted to debug by trying to send error messages to the error log without success. Does anyone have any suggestions on how I can determine why the translation handler is entering into a continuous loop when a request is sent from Netscape? I would be appreciative of any help!!

Best GCC compiler options for Intel (perl apache)
Can anyone recommend extra gcc options to squeeze the last ounce of performance out of code (perl and apache in this case) on Intel? I don't mind tying the code down to one cpu type or loosing the ability to debug etc. We're already doing -O6 and are looking for more. I recall Malcom Beattie (CC'd, Hi Malcolm!) experimenting in this area, something about not wasting a register for the frame pointer. I'm using gcc 2.95.2, is that the latest/best? It's on FreeBSD 4.1 and 4.2. Tim.
RE: Development Environment
I actually was nearlly successful in accomplishing some sort of mechanism by which developer packages can be mapped to a virtual package which the real package points to (did this make sense?). Anyway, it needed to tap into the symbol table way too extensively and ran into several problems. I also thought about configuring the apache server differently on development so that child processes get recycled much faster than on production so as to allow for each request to use it's own memory. This can be resource intensive but again it would only be on development. Also, packages/modules will need to be called on a per request basis in development. I will let you know if it is feasible. Thanks, I agree. I've seen many people try to do shared memory/cached programming in one server and it just doesn't work very well in practice. It only takes one programmer a typo to take everyone else down until the bug is fixed. From Jakarta/Tomcat to IIS to Apache/mod_perl. Developers having their own workstation is the best for testing and active development. Of course, a staging server needs to be shared. But it's a lot cleaner once the developer has debugged their own code.
Re: How do I debug failed tests? (error_log isn't helping)
make test has various errors (failed 18 total) how do i debug these and fix them? The test routines are just ordinary perl code that exercise various portions of the module. It is like debugging any other perl code. I don't suppose that was the answer you wanted, but that's the way it works.

Re: Newbie mysterious 500 error with PerlFixupHandlers
We are using
RedHat Linux apache 1.3.14 mod_perl_1.23_01
Our site is set up to generate pages using a templating system to add
custom headers footers and sidebars. As well we use .htaccess files to
further customize the subprocess_env.
We are using custom modules installed as PerlFixupHandlers both for
template generation and multilingual negotiation
Negotiation.pm handles lingual content negotiation. It determines
what version of the page to present based on the users preferred
variants and the available variants for that page.When the best match
is found, it
performs an internal redirect to that document.
Template.pm is installed as a fixup handler, and is controlled through
various PerlSetVar directives.
Basically, it determines what to include at the beginning and end of
the web page.
fixup sets the content handler for the request.
Also has two subroutines, handle_rec for static pages ,and handle_cgi
for scripts These allow the auto-inclusion of headers and footers of web
pages.
In httpd.conf
--
DirectoryIndex index.cgi index.html
PerlRequire /www/perl/libs/WRI/Template.pm
PerlRequire /www/perl/libs/WRI/Negotiation.pm
PerlFixupHandler WRI::Negotiation WRI::Template::fixup
---
These modules work 90% of the time
The problem occurs when a directory is requested, and served as a
negotiated document
and is passed to our content handler. (handle_cgi)
A save-as window pops up in the browser and Apache logs a 500
error. (The file it is trying to save is the standard 500 internal
error message.)
In the Template::fixup handler, the
document is being detected as a cgi-script, not a server-parsed
document. The 500 occurs because we are trying to execute a static
document or directory.
Template.pm
In run_cgi:
unless (open(CGI,'-|')) {
#don't need the writing handle to the pipe anymore
close(WR);
#make STDIN be the read handle of the pipe (so we can get
#POST information from Apache)
open(STDIN,'RD');
#Run in the directory of the file
$r-chdir_file($filename);
### This returns 500 when a directory or static file is negotiated ###
#Run the file
exec($filename) || return SERVER_ERROR;
}
Error Log:

-
My understanding is that when OK or DECLINED is returned from these
modules in the list of fixup handlers, control passes to the next,
and when DONE is returned, the remaining are
skipped mod_dir regains control and the next default file is requested
(index.cgi index.html)
Is this correct or is there something I am misunderstanding.
Request Outline
---
mod_dir sends directory request to Negotiation.pm
/products/student/calcwiz/
returns OK from Nego.pm
mod_dir then sends index.cgi - index.html
Nego.pm negotiates index.cgi and each of available variations
then index.html ..
when found most appropriate
Negotiating:

Template.pm

Another Clue
This error recurs when the page is reloaded 25 - 30 times

Could this be related to our problem.

RE: [OT] Dynamically changing current package
Andrew Ho [EMAIL PROTECTED] wrote:
I know how to use "package" in the normal case, where it's static.
However, you can't say "package $foo" or even "eval 'package
foo'" or even "BEGIN { eval 'package foo' }." I'm wondering
if there's any way short of hacking the Perl source itself
to make the compiler dynamically choose a namespace.
The reason your eval examples don't work is because the scope of the package
declaration only extends to the end of the current block, the end of the
current file, or the end of the current 'eval', whichever comes first.
If you want to put code into a particular package at runtime, you have to
recompile that code along with the package declaration:
eval "
package $foo;
$scalar_containing_some_code
";
Or you can pull in the code from an external file:
eval "
package $foo;
do '$script';
";
The package declaration is scoped the way it is is because it is a
compile-time directive, not a run-time directive. Code is placed into a
particular package at compile-time; to change the package of a particular
piece of code at run-time really means to destroy that compiled code and to
recompile it in a new package. This is essentially what happens when you
use the string form of eval, above.

RE: Translation handler continuous loop problem
This is a repost because my earlier message from this morning bounced. Since
then I feel we have located the source of the problem. It looks like there
is a most bizarre interaction between Netscape clients and the proxy server.
Netscape was configured with manual proxy settings identifying the web
server with Apache/mod_perl. Once this was done, Netscape is able to
successfully connect to Apache/mod_perl with no more continuous loops!! I
don't know the whys or hows.
The following text is a copy of what I posted this morning.
Thanks for the example. I inserted the statement "return DECLINED unless
$r-is_initial_req;" but the handler still enters a continuous loop. I
also stripped out my code and tried the example from Doug's module book with
debug statements but still a continuous loop. The problem is bizarre. It
only enters the loop for a URL like http://lions/sp9/whatever Any other URL
such as http://lions/here/there works fine. I wrote the original handler to
extract a session id from a URL with sp9 in the path but now there is no
reference. I have checked my httpd.conf for anything out of ordinary as
well. As can be seen, the translation handler below is very very basic but
it still enters a continuous loop for that specific URL. If I place a fully
qualified donamin name like http://lions.access.com/sp9/whatever, there is
no loop!!
Any ideas?
package Apache::URIsid;
use strict;
use Apache::Constants qw(:common);
use CGI::Carp;
sub handler {
my $r = shift;
return DECLINED unless $r-is_initial_req;
my($junk,$session,@rest) = split '/', $r-uri;
# warn "junk: $junk";
# warn "session: $session";
# foreach (@rest) {
#warn "rest: $_";
# }
my $uri = $r-uri;
warn "URI in: $uri";
return DECLINED;
# my $uri_in = $r-uri;
# warn "sp9 URL detected $uri_in";
# $r-subprocess_env('SESSION_ID' = $session);
# my $translated_uri = join "/", "",@rest;
# $r-uri($translated_uri);
# return DECLINED;
}

I could be completely wrong but ...
I can't see a problem here - although I would need to see the code.
There could be an issue with how IE and Netscape actually format the
header (i.e you may enter the above, but the header that gets sent may
be different) - but I could be completely wrong on this !
You may wish to look at http://sourceforge.net/projects/sessionmanager/
Which is URI transhandler / session manager that I wrote for a project
that never came about. I may make another release that uses PerlSetVars
to configure the module if I get a chance to test it.
If this does not help, then post either the code, or a URL to the code
if its long, so that some of us can have a look.

RE: [OT] Dynamically changing current package
You can also change the package using globs.
*{NewPackage::} = *{TestPackage::};
NewPackage will then contain all things in TestPackage
Then you can redefined everything in TestPackage without affecting
anything in NewPackage.
You can also do something like
for my $name (keys %{Test::}) {
*{"NewPackage::".$name} = *{"Test::".$name} if($name =~ /somefunc/);
}
That's a poor mans export
You can also load different modules based on developer if you force
them to log in and create packages preceeded by their usernames
$user = $r-connection-user; # right?

I know how to use "package" in the normal case, where it's static.
However, you can't say "package $foo" or even "eval 'package
foo'" or even "BEGIN { eval 'package foo' }." I'm wondering
if there's any way short of hacking the Perl source itself
to make the compiler dynamically choose a namespace.
The reason your eval examples don't work is because the scope of the package
declaration only extends to the end of the current block, the end of the
current file, or the end of the current 'eval', whichever comes first.
If you want to put code into a particular package at runtime, you have to
recompile that code along with the package declaration:
eval "
package $foo;
$scalar_containing_some_code
";
Or you can pull in the code from an external file:
eval "
package $foo;
do '$script';
";
The package declaration is scoped the way it is is because it is a
compile-time directive, not a run-time directive. Code is placed into a
particular package at compile-time; to change the package of a particular
piece of code at run-time really means to destroy that compiled code and to
recompile it in a new package. This is essentially what happens when you
use the string form of eval, above.

RE: suexec denies execution of scripts
Because suexec is build with a predefined path which allows only scripts underneath that path to run in. You need to find out what the 'docroot' is and be sure that your script is underneath this path. There are several other restrictions that need to be done to ensure that cgi's being run under suexec need to adhere to. http://www.apache.org/docs/suexec.html I respectfully request your help in order to get this working. My .cgi are not perl ones, but /bin/sh or whatever you want that works with suexec. I DO known this list is exclusive for mod_perl. But since i get no ideia where to go to seek for help. (as far as i known, there is no mailing list support for apache/suexec in www.apache.org). May some one (In the name of God) help with such, **PLEASE** ?
RE: [OT] Dynamically changing current package
NewPackage will then contain all things in TestPackage Then you can redefined everything in TestPackage without affecting anything in NewPackage. Actually it will, if you were to delete NewPackage, TestPackage would not contain anything. Modifying 'thingys' in TestPackage would modify NewPackage.

If you really want to go crazy, you could try -fbranch-probabilities (requires more than just turning it on; read the gcc man page.) I doubt it's worth the trouble. And you'd probably want -march=i686 (or whatever CPU you're using). I don't know the state of pentium-specific optimizations, but does Cygnus's Code Fusion still have a gcc with Pentium-specific optimizations that aren't in the main tree? I just remember the numbers saying that they'd slightly overtaken Intel's compiler, but that was a year and a half ago. Unrelated to the compiler, if you're throwing around significant chunks of data, you might want to try tuning your drives. Especially if they're IDE, since UDMA is often disabled for safety by default. I don't know much about SCSI tuning, but whichever interface you're using, make sure the heads are able to go around in circles really fast. You can also play tricks with RAM disks, or solid-state hard drives like the ones from platypustechnologies.com. But this gets too far afield.

The percentage improvement varies greatly between applications but is often around 10%. If you're willing to use a commercial compiler instead of gcc, I get a 20-40% improvement with Intel's proton C compiler (which I think is only available commercially for Windows so far) over gcc and have found other commercial compilers to produce similar gains.

DBD::mysql memory leak!
I have been testing and troubleshooting this for days, and I can find no
other answer to my problem except that DBD::mysql has a memory leak.
I have narrowed it down to this small script running through
Apache::Registry:
use DBI;
use DBD::mysql;
use strict;
print "Content-type: text/plain\n\n";
my $dbh = DBI-connect("dbi:mysql:db;host=localhost", "user", "pass")
or die "no DB!\n";
my $sth = $dbh-prepare(q{
select * from junk where id = 10
});
$sth-execute() or die "no sql\n";
while (my @row = $sth-fetchrow_array())
{
print join("\n", @row), "\n";
}
$sth-finish;
$dbh-disconnect;
This script runs just fine, and displays the contents of the single
specified MySQL row. However, if I watch the size of my httpd process, it
will grow over time as I access the script repeatedly.
I use the following script to load test it:
use LWP::Simple `get`;
$uri = shift;
$hits = 0;
$SIG{INT} = sub { print "fetched: $hits"; exit };
while(1) {
get $uri or die "get failed!";
$hits++;
}
I am using the latest DBD::mysql module, as far as I can tell. I forced a
reinstall with CPAN shell, just to be sure. Here is my version info:
Msql-Mysql-modules-1.2215
Embedded Perl version v5.6.0 for Apache/1.3.12 (Unix) mod_perl/1.24
As common as this mod_perl/DBD/MySQL combination is, SOMEBODY else has to
have had this same trouble and solved it. Right? ... Right?

RE: Prototype mismatch in Apache::PerlRun line 343
Hi Doug,
Just installed Apache 1.3.7 and mod_perl 1.25 on my Linux box. To my
surprise, when I ran my scripts using PerlRun.pm, the "Prototype mismatch"
problem still occurs. When examining the code, it happened to be that line
344 of the new PerlRun.pm is:
*{$fullname} = eval "sub ($p) {}";
instead of
eval "*{\$fullname} = sub ($p) {}";
Apparently, the line in PerlRun.pm (mod_perl 1.25) is not doing what it
should do, which is replacing the sub that $fullname points to with a empty
sub with correct prototype. Is there anything I am missing here?

More Info: DBD::mysql leak!
Ok, through more trial and error, I've managed to whittle the offending script down to this: use strict; print "Content-type: text/plain\n\nHello World!"; That's it, and it still leaks. So, apparently the problem is not with DBI or DBD::mysql at all. The only components left seem to be Apache, mod_perl, and Apache::Registry. I'll keep experimenting. Let me know if any of you experience similar problems with this script. Mark Blythe [EMAIL PROTECTED]
