How tell what version of mod_perl is installed?
I ran into some problems trying to get a Perl CGI script to make use of IPC::Sharelite, so I want to understand the Apache and mod_perl threading model in order to be able to use shared memory across multiple Apache threads. For starters, I better make sure I learn more about mod_perl 2.0, as in, do I even have it on my system yet! I am running Red Hat 8.0, Apache/2.0.40. How do I tell if mod_perl 1.0 or mod_perl 2.0 is installed (or, at least, that the .so is the .so for mod_perl 2.0)? Some facts about my system that may help answer this question are provided below...

Re: Perl Run and Load Average
Hi Stas, Based on your previous questions, my guess is that you are using mod_perl 1.99_09. Please be more verbose about your setup when asking questions. Sorry, here is my setup. mod_perl-1.99_09 httpd-2.0.40 Do you preload the modules that you use at the server startup? Your PerlRun scripts should be the only ones that get recompiled. Try moving all the standard modules to startup.pl and see if it gets any better. My startup.pl looks like: #!/usr/bin/perl use Apache2; use Apache::compat (); 1; I will try to move all standard modules to startup.pl. Do I need to delete the standard modules from the scripts after I moved them to startup.pl? I mean, after I moved: use MyModule; to startup.pl, do I need to delete it from the scripts? Or Perl Run will automatically figure out that it has already been loaded and simply ignore the one in the scripts? Any reason why you don't use ModPerl::Registry? Yes, since the scripts were running under plain CGI, they produce too many errors if run under ModPerl::Registry. I am working on them, and use PerlRun for the moment. PS. Congratulations on the publication of your new book :)
Re: Perl Run and Load Average
Assuming your CGI scripts aren't doing strange things, liking hanging around after the session has closed and doing clean-up work, you might check your httpd.conf settings on the number of threads and requests per threads. Its possible that your httpd threads are short-lived and restarting more often which now requires a lot more work to start since Perl is being loaded each time - just an idea. MaxRequestsPerChild 1000# if this were too low, say 10 or 50, you would probably create more load # If these were out of wack somehow, it could possibly create some unusual load conditions MaxSpareServers 20 MinSpareServers 5 I would also run top -d 1 while your webserver is running without mod_perl to see what scripts are causing the load. Do you have a database running on the same system? Do you know if it might be doing more work? Stas already mentioned the pre-loading of modules which will help, but not much if you have a misconfigured httpd.conf as mentioned above. dale - Original Message - From: Batara Kesuma [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, June 05, 2003 5:23 AM Subject: Perl Run and Load Average Hi, I have changed all my CGI scripts to run under Perl Run, and now I notice that the load average of my server (it is a dual CPUs) is very high.

DirectoryIndex doesn't see SetHandler path
This is going to seem odd...obscure...dumb... I've been using code like this to set up handlers: Location /some/path/index SetHandler perl-script PerlResponseHandler Some::Handler /Location Now I'm using this code to set up handlers for individual pages. The directive above is in a sense telling Apache there is a directory /some/path/index which contains files which should be processed via Some::Handler but in fact there is no such directory. There is just a handler. So in my mind I'm defining a single page with a handler. All this works OK, weird though it may be, until I want a directory index. Say I want to go to url: /some/path The DirectoryIndex directive doesn't allow me to say that 'index' is a directory, only 'index.html'. That is to say, the following: DirectoryIndex index index.html doesn't cause Apache to automatically find /some/path/index, even if I have defined one using AddHandler. I'm assuming this is because there is no such file, the handler is attached to the /some/path/index directory, there isn't anything for Apache to find. For the moment I'm faking things out using the miracle of mod_rewrite: RedirectMatch ^/some/path/index\.html /some/path/index which makes it all work like I want. NOW Apache finds the handler for some reason. So I'm not complaining, and I don't need a fix, but I wonder if I'm missing something. * AddHandler attaches a handler to a set of files with a given suffix. * SetHandler attaches a handler to a location (a directory, right?) and all of the files therein. * There isn't (?) a directive that attaches a handler to a single leaf in the directory tree which may in fact be non-existent in such a manner that the DirectoryIndex directive will find the leaf. Have I missed something? Am I abusing the tool? mma

So get yourself familiar with the infrastructure, but don't do anything just yet. We have planned a bulked import of documentation bits from the Apache C header files, but it's incomplete. Seeing that it's not getting anywhere and hearing no news from Gerald Richter, I think I'll just go ahead and import whatever we have. And then everybody can chime in and help polish the docs.

I am trying to find documention on members and methods of, for example: use Apache::RequestRec (); use Apache::Connection (); For example, looking thru my installed 'tree', the only thing if find for 'RequestRec' is RequestRec.pod which only goves information on members server and dir_config. But I know (from testing the example LoaHandler in the 2.o documentation) that RequestRec is far richer than that, containg, for example: ... my $entry = sprintf qq(%s [%s] %s %d %d\n), $r-connection-remote_ip, scalar(localtime), $r-uri, $r-status, $r-bytes_sent; ... I don't mean this question to be specifically about RequestRec, but rather am seeking to find out how to find the structure of Apache/mod_perl creatures in general. (Yes, I even can read c if that's were the documentation lies). Aloha = Beau.

Re: mod_perl and CGI.pm and version 1.x and hell
it helps when problem reports include information that helps to debug the problem. We can't possibly guess what setup you are using. In this case which CGI version are you using? CGI 2.93 works just fine with mp1 and mp2. CGI.pm does 'require Apache' only if it detects no mod_perl 2, but mod_perl 1. Stas, I thought I had the latest version, but you helped to realize I didn't. By mistake I downloaded and used version 2.753, thinking it was the lastest one available, when actually it's from March 2001. The followin URL from CPAN confused me (CGI.pm-2.753.tar.gz appears after CGI.pm-2.93.tar.gz): http://www.cpan.org/modules/by-module/CGI/ Anyway, 2.753 didn't work, but 2.93 seems to work fine. This is completely my fault, sorry for the trouble. Regards, Henrique.
Re: [mp2] make test fails to start httpd
I am having the exact same test failure results on openbsd, and the archives show that some people have had similar problems, with no resolution that I have seen. what happens if you manually run /usr/local/apache2/bin/httpd -X -d ./t -f cont/httpd.conf from within the toplevel mod_perl-1.99_09 directory? the -X tells apache to run as a single process, no forking. the problem on openbsd is that the fork'd child processes are getting segfaults somewhere in libperl.so, but the parent process is doing its thing (fork'ing children) and returning successfully. I didn't post a bug report here because I think its a problem with perl on openbsd. Could this be a mod_perl problem? the segfaults are due to attempts to access mem 0xabababab which is a special value that perl uses (with the Poison macro) to try to make catching segfaults easier.

Re: [mp2] make test fails to start httpd
Dave wrote: I am having the exact same test failure results on openbsd, and the archives show that some people have had similar problems, with no resolution that I have seen. sure, and it was the same problem with aix earlier. The problem is with DSO loading and it's a different problem on each platform, though it inhibits itself in the same way to user's eye ;) what happens if you manually run /usr/local/apache2/bin/httpd -X -d ./t -f cont/httpd.conf from within the toplevel mod_perl-1.99_09 directory? the -X tells apache to run as a single process, no forking. the problem on openbsd is that the fork'd child processes are getting segfaults somewhere in libperl.so, but the parent process is doing its thing (fork'ing children) and returning successfully. I didn't post a bug report here because I think its a problem with perl on openbsd. Could this be a mod_perl problem? the segfaults are due to attempts to access mem 0xabababab which is a special value that perl uses (with the Poison macro) to try to make catching segfaults easier. I'm kinda stuck. You don't tell which version of OpenBSD you are on. Philippe and I have spent a lot of time trying to make it working on OpenBSD 2.9, but weren't successful. I couldn't even run mod_perl 1, DSO with customly built perl. Using the system 5.6.0 perl was good for making mod_perl 1 DSO working, but it's of no use to mod_perl 2.0. The problem is that system 5.6.0 perl was customly build and I wasn't able to produce a similar version for 5.6.1 or higher and OpenBSD 2.9 is no longer supported, so 5.6.0 is the best you can get. FWIW, Philippe reported having no problems running mod_perl 2.0 on OpenBSD 3.3 (though I think you need to use current cvs for that). __ Stas BekmanJAm_pH -- Just Another mod_perl Hacker http://stason.org/ mod_perl Guide --- http://perl.apache.org mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com http://modperlbook.org http://apache.org http://ticketmaster.com
