building mod_perl against multiple apache's, make test fails looking for apr.so
Hi Folks, I'm trying to set up a dev box with both apache 2.0.55 and 2.2.0 . Since I've got both, I didn't want to set /usr/local/http-2.0.55/lib in my /etc/ld.so.conf since then the 2.2.0 binaries might look at the wrong APR (well.. that's my guess). I tried: perl Makefile MP_APXS=/usr/local/httpd-2.0.55/bin/apxs MP_APR_CONFIG=/usr/local/httpd-2.0.55/bin/apr-config It builds without error. Make test fails a number of places because it can't find apr.so. If I set /usr/local/httpd-2.0.55/lib in ld.so.conf, or set SETENV LD_LIBRARY_PATH then all is well, but then what about 2.2.0? If mod_perl is running under a particular apache as a dso then does it just inherit the right apr and the make test is nothing to worry about? Thanks for any insight you can provide.

you could also try this: store to /whatever/ read from memcached failover to /whatever/ assuming you have the memory for it, it should handle spikes very well

Well, that is not entirely true at least if the mentioned patch is applied.
For example AllowOverride cannot be used in a .htaccess. But with the patch
you can say:
$r->add_config( ['',
'AllowOverride AuthConfig Options=Indexes,ExecCGI',
'',
], ~0, '' );
If done in a MapToStorage handler that returns DECLINED it even affects the
subsequent processing of a .htaccess file.
Or to do something like .htaccess processing:
use Apache2::Access;
use Apache2::RequestUtil;
{
local @ARGV=($htaccess_file_name);
$r->add_config( [<>], $r->allow_override, '/', $r->allow_override_opts );
}

The downside of your approach is that it can't scale across a cluster of machines, and has no on-disk backup. If you only have one machine, it's probably fine. - Perrin
Re: Apache::Session::MySQL lock troubles
I've been using Apache::Session::MySQL for a while, but I've been trying to lower the amount of database I/O in some applications that experience spikes in server traffic. So I came up with the idea of using Apache::Session::File with the files on /dev/shm, with a cron job to clear up old or expired sessions. Preliminary benchmarks found this to be about 7-8 times faster than MySQL. I'm curious if anyone else has tried this, and if they can think of any reasons why this would be a bad idea. Dan
RE: Content Disposition header and file contents sequence...
Just as I give up and email the list
I figured out that the database wasn't returning the filename so it
wasn't able to open the file for download so when I hard coded a

those definitely need to be reversed - you need to send the headers before
you send any output.

Content Disposition header and file contents sequence...
This is the relevant part of my handler for a link that I want to force
a download for. I know it's content-disposition but for some reason I
can not get it to actually download the file. I get the download dialog
and I choose the location to save it but when I open the document it is
empty. I've tried changing the sequence of the items but it never works.
my $filename = "/usr/local/app/media/videos/downloads/preview.mov";
unless ($fileFH = Apache::File->new($filename)){
$r->log_error("couldn't open $filename for reading: $!");
return SERVER_ERROR;
}
$r->content_type('video/quicktime');
$r->headers_out->set('Content-Disposition' =>
"attachment;filename=$downloadFilename");
$r->send_fd($fileFH);
$r->send_http_header();
return OK;

Re: Perl Script using MapToStorageHandler
Sure id love to see that script... to be completely
hones im still kinda new to perl even... Im getting it
slowly... Anyway, im just looking to achieve my goal
and that is to have a working script/perl module that
can switchout config based on incomming URI... a
perfect example would be the one im working on now...
the Subversion/Dav one...

Apache 1.34, mod_perl 1.29, Apache::ASP based application
This message will be separately posted to the Apache mailing list as I'm not sure if it's a mod_perl/apache::asp deal or apache. I have recently come across an issues where I ran out of file handles and couldn't open up any files. This is, as you know a mod_perl Apache::ASP based application (don't flame me, I didn't start it, just just support it). The problem occurs on Linux (2.6.9 - RedHat EL4 update 2). Vanilla Perl 5.8.7, apache, mod_perl, mod_ssl install. These binaries are separate of the base directory structure The very same application works fine with default apache 1.3 server tuning on Solaris 8. We are in the process of moving these applications to Linux. For the most part the software versions are the same on both platforms with exception of the minor versions. here is a few lines from lsof that look to be eating up the filehandles and not releasing them: httpd 17196 nobody 93u sock 0,4 11020434 can't identify protocol httpd 17196 nobody 94u sock 0,4 11020606 can't identify protocol httpd 17196 nobody 95u sock 0,4 11020717 can't identify protocol I have the MaxRequestsPerChild set to 5000. This seem to control things at an acceptable level of file handles by killing off processes, once killed off, large blocks are released.. The apache processes do not look like they make it over 60meg in size either.. But this isn't the right way to do this I'm sure. ideas? -- Jason Czerak ([EMAIL PROTECTED]) __ This email transmission and any documents, files or previous email messages attached to it may contain information that is confidential or legally privileged.

Re: Perl Script using MapToStorageHandler
thanks for the detailed explanations. torsten++ :) > That leads to an error saying that " But, a few thing cannot be applied by means of $r->add_config. For example > "AllowOverride" needs a "Directory" block I think what most people don't understand about $r->add_config() is that it's .htaccess-style configuration injection. so, if you can't use a given config from an .htaccess file you can't use add_config() for it either. all the rest is good stuff and on target :) --Geoff
