Memory corruptions with mod_perl on win32
Hi, I use Steve Hay's mod_perl binaries with ActiveState perl 5.16 http://people.apache.org/~stevehay/ I see these kind of memory corruptions in the apache log when I put some serious load on the server via ab.

Running a proxy in front of mod_perl on Win32

It can serve thousands of simultaneous connections and still has just a memory footprint of a few mb. I dont know if the event-model works as great under windows but there are windows builds available on the website (http://nginx.org) so it should be worth a try. Hendrik

There are various flaws in the build, report them to d...@httpd or collect them in bugzilla reports, and mind the existing reports which might already solve your problem. Since there is no MinGW port maintainer, this often falls apart, sorry there is nothing we can do if a platform's community does not participate with or engage the developers with patches. Also if you'd try to compile mod_perl it will try to run ./configure on the Apache sources but that will fail on Win32 because 1. there is no Configure in the win32 Apache sources and 2.

You don't use the -win32-src package because that package is for building on the Microsoft Windows platform. If you want to build for a faux-unix platform you would obtain the usual tarball.

Here is how I installed StrawberryPerl + mod_perl + apache2 on Windows
(tested onVista):
1. Apache
Go to http://httpd.apache.org/download.cgi
Click on /Win32 Binary including OpenSSL 0.9.8i (MSI Installer) /
Some recommend to install it in a directory without space, although I
did not do that and it still work.
2. Perl
Go to http://strawberryperl.com/ and install the latest kit
3. I then use the script send in attachement to install all modules I
need, e.g. perl install_modules.pl
At the top of the script you will see how to get mod_perl2 and various
other stuff I need for my project. Just the lines for the modules you do
not need.
HTH,
Cheers, JD.

mod_perl / Perl5.10 / Win32 ?
Hi all, I don't know where to find answers to the following questions, so better ask the list : - 1) is modperl2 currently compatible with Perl 5.10 ? If not, are some people working on it ? For which target date ? - 2) if the answer is YES, then did anybody compile it into a PPM for Win32 ? Didn't find it at ActiveState nor at uwinnipeg. Thanks in advance, Laurent Dami

As there's been several requests for this, I've put up an ActivePerl 10xx ppm package of mod_perl2, based on the current svn sources, at http://cpan.uwinnipeg.ca/PPMPackages/10xx/ which you can install via C:\ ppm install http://cpan.uwinnipeg.ca/PPMPackages/10xx/mod_perl.ppd There's also a ppm package of libapreq2 (which supplies, amongst other things, Apache2::Request and Apache2::Cookie) in the same repository.

Mod_perl and win32 --more experience
Hi all, There has been quite a few reports about mod_perl causing segment faults in Win32 boxes on the list (including me). Thanks to all that responded with suggestions. Here is my latest findings: 1- I have mod_perl2.0.3 apache2.2.4 working on a Windows 2003 box.(Dual xceleron IBM server) 2- Using standart binaries for perl (activePerl and Apache) is perfectly fine. No need to compile them yourself. 3- XML::Libxml or anything that uses it like XML::Simple will definitely crash the system under heavy load. I now use Expat and under most heavy tests it survives. This is a very usefull package and may be somebody will look into it. 4- Another culprit was a not a very common package HTML::Template::Pro. Segment faults (saying free to wrong pool) again under heavy use. I now use HTML::Template and works fine. So I can now say Mod_Perl rocks on a production Library system running on Windows Box. Hope it helps to others Tumer Garip
