During my work on the ENodes project, i've developed a tiny threaded logger in c to manage internal logfiles (by webmaster/website/version). (you can rewrite it in perl with a 5.8.x built with thread...) Perl handlers send log lines through a UNIX socket to the logger which is opening logfiles when needed and keeping them opened. It avoids the overhead of opening and locking each time the file and provides as many online debug logfile as you ask. The logger is launched in a 'PerlRequire' file. The client have a persistant connection to the logger. If it fits your needs, you can get sources here: http://www.enodes.org Server : utils/enodes_logger/enodes_logger.c Client module : enodes_core/modules/ENodes/Core/ApLog.pm Cheers -- Guillaume FOUGNIES
Perl Handlers and namespaces.
I ran into this problem today. I am trying to develope a small application server with a few handlers and Apache/1.3.22 . So I have something that looks like this set up in the apache conf file: Allow from all PerlRequire "startup.pl" SetHandler perl-script PerlHandler AppServer AuthName "AppServer" AuthType Basic PerlAuthenHandler AppServer::Auth require valid-user PerlAccessHandler AppServer::Access Now, you notice that these packages are all under the same namespace. This, somehow, causes an 'Undefined subroutine &AppServer::handler called.' each time the server recieves a request from a client. However, if i move the main handler into another namespace or simply rename it to foo.pm ( and adjust the apache conf file of course ) the error magically disappears. If one of the access handler or authentification handler is under the same namespace as the main handler, i always get the undefined subroutine error msg. I'm not sure why or how apache handles this or if it's a bug or if i'm just too tired and missed something somewhere else. I would appreciate someone's insight on this. Is it a bug / limitation /... ? Thanks for your time, Guillaume

Apache et perl
J'ai installé Apache 1.3.12, Perl 5.6.0 sous Mandrake 8.0. J'ai la page HTML suivante (sans les <>) (dans /var/www/html): html head title Page de Test /title meta name="author" content="denizot" /head body form action="../cgi-bin/base.pl" method="GET" input type="Text" name="saisie" value="" size="10" /form /body /html et le script perl (dans /var/www/cgi-bin) suivant: #!/usr/bin/perl -w # base.pl printf "Content-type: text/html\n\n"; print "ca marche pas\n"; J'ai modifie httpd.conf pour que /var/www/cgi-bin soit un Directory avec Options ExecCGI. Lorsque je tape http://nom_de_host et que je presse Enter apres la saisie, une page HTML Internal ERROR me saute au yeux. Par contre, lorsque je tape http://adresse_ip et que je fais la meme manip, une fenetre "Enregistrer sous..." apparait. Quelqu'un a-t-il eu le meme probleme ou comment le resoudre? _ Le journal des abonnés Caramail - http://www.carazine.com
