[BlueOnyx:11353] Re: Web alias turn off PHP

[Michael Stauber]

Hi Steven,

>> I've had a look in /usr/sausalito/conf/base/apache/Apache.conf and I *think* the handler should be running. My knowledge of this area is somewhat sketchy though. Perhaps Michael may have some input as to what's called and when. To me it looks like webscripting.pl (or webscripting2.pl ?..) isn't being called for some reason, so this section isn't making it to the config file.

VALIDATE, CONFIGURE, EXECUTE, TEST, CLEANUP stages all serve different
and specific purposes and are called in sequence. Something that is
called via VALIDATE will always be called before something that's called
via CONFIGURE. If left blank, EXECUTE will always be assumed.

So while the various stages come in sequence, there is no guarantee in
which sequence scripts within the same stage might be called.

Let us take a look at a part of Apache.conf:

# Vsites have a seperate namespaces for php, cgi, ssi and
enabling/disabling user webs
Vsite.PHP.*             perl:base/apache/webscripting.pl CONFIGURE
Vsite.CGI.*             perl:base/apache/webscripting.pl CONFIGURE
Vsite.SSI.*             perl:base/apache/webscripting.pl CONFIGURE
Vsite.*                 perl:base/apache/webscripting.pl CONFIGURE #*OLD
Vsite.USERWEBS.*        perl:base/apache/userwebs.pl CONFIGURE

Vsite.PHP.*             perl:base/apache/reload_httpd.pl CLEANUP
Vsite.CGI.*             perl:base/apache/reload_httpd.pl CLEANUP
Vsite.SSI.*             perl:base/apache/reload_httpd.pl CLEANUP
Vsite.USERWEBS.*        perl:base/apache/reload_httpd.pl CLEANUP
Vsite.webAliases.*      perl:base/apache/webscripting.pl CLEANUP #*NEW

webscripting.pl is called in the CONFIGURE stage whenever *anything* in
a "Vsite" object is added, updated or removed. That ought to be
sufficient. But in fact it isn't. When you add or modify the "webAlias"
of a Vsite, the virtualhost container of the Vsite will be rewritten
from scratch with the PHP or suPHP related entries gone walkies.

So I went in and call it again in the CLEANUP stage, but only when the
"webAliases" of a "Vsite" object are added, updated or removed. So this
makes sure that webscripting.pl is run at the end of the sequence and
adds the PHP or suPHP related lines in case they're gone.

In the testing that I did, this seems to work pretty well.

I'm just publishing that change to SVN and to YUM:
