apache::db
DB(3pm) User Contributed Perl Documentation DB(3pm)
NAME
Apache::DB - Run the interactive Perl debugger under mod_perl
SYNOPSIS
<Location /perl>
PerlFixupHandler +Apache::DB
SetHandler perl-script
PerlHandler +Apache::Registry
Options +ExecCGI
</Location>
DESCRIPTION
Perl ships with a very useful interactive debugger, however, it does not run "out-of-the-box" in the Apache/mod_perl environment.
Apache::DB makes a few adjustments so the two will cooperate.
FUNCTIONS
init
This function initializes the Perl debugger hooks without actually starting the interactive debugger. In order to debug a certain
piece of code, this function must be called before the code you wish debug is compiled. For example, if you want to insert debugging
symbols into code that is compiled at server startup, but do not care to debug until request time, call this function from a
PerlRequire'd file:
#where db.pl is simply:
# use Apache::DB ();
# Apache::DB->init;
PerlRequire conf/db.pl
#where modules are loaded
PerlRequire conf/init.pl
If you are using mod_perl 2.0 you will need to use the following as your db.pl:
use APR::Pool ();
use Apache::DB ();
Apache::DB->init();
handler
This function will start the interactive debugger. It will invoke Apache::DB::init if needed. Example configuration:
<Location /my-handler>
PerlFixupHandler Apache::DB
SetHandler perl-script
PerlHandler My::handler
</Location>
SELinux
Security-enhanced Linux (SELinux) is a mandatory access control system many linux distrobutions are implementing. This new security scheme
can assist you with protecting a server, but it doesn't come without its own set of issues. Debugging applications running on a box with
SELinux on it takes a couple of extra steps and unfortunately the instructions that follow have only been tested on RedHat/Fedora.
1) You need to edit/create the file "local.te" and add the following:
if (httpd_tty_comm) {
allow { httpd_t } admin_tty_type:chr_file { ioctl getattr }; }
2) Reload your security policy.
3) Run the command "setsebool httpd_tty_comm true".
You should be aware as you debug applications on a system with SELinux your code may very well be correct, but the system policy is denying
your actions.
CAVEATS
-X The server must be started with the "-X" to use Apache::DB.
filename/line info
The filename of Apache::Registry scripts is not displayed.
