Re: lost directory indexes
:)
You put almost as much effort into this as I, and I have to admit, this
is fairly fustrating, and it is just an old bug, one that should
have been resolved long ago. And I think the bug is in apache, not
mod_perl, but I could be wrong. I was going to, on my next attempt on
this, try recompiling the apache and modperl code with some alterations
but then I discovered that I might not have correct information.
Is it that mod_dir has to run first BEFORE embperl
or does embperl have to run first, which is what
we have been concluding.
I think mod_dir has to run FIRST... why?
Because if you get a directory, it needs to translate it to an html file
FIRST, fetched anded off to embperl and mod_perl.
My regular perl module though needs to go FIRST and then hand off to
mod_dir. Why? Because it is examining the url for nastiness. Once it
is ok, it should hand off to mod_dir... which seems to be what is
broken.
When I run embperl, which will only work with
sethandler perl-script, and never with addhandler: see below
it functions fine until I add the mod_perl module I wrote. So
mod_dir is probably supposed to be sliced between them.
<VirtualHost *:80>
ServerAdmin ruben@mrbrklyn.com
DocumentRoot "/usr/local/apache/htdocs/nylxs"
ServerName www.nylxs.com
DirectoryIndex index.html
PerlModule Embperl
Embperl_UseEnv on
ErrorLog logs/nylxs_error_log
CustomLog logs/nylxs_access_log common
<Directory /usr/local/apache/htdocs/nylxs>
Options Indexes ExecCGI
DirectoryIndex index.html
<Files *.html>
SetHandler perl-script
# PerlResponseHandler URL_BLOCK
PerlHandler Embperl
</Files>
AllowOverride None
Order allow,deny
Allow from all
</Directory>
</Virtualhost>
When I use AddHanlder with my custom mod_perl url module, the mod_dir
stuff works and it seems to handoff to mod_dir correctly
For example:
<VirtualHost *:80>
ServerAdmin ruben@mrbrklyn.com
DocumentRoot "/usr/local/apache/htdocs"
ServerName www.mrbrklyn.com
Options Indexes
AddHandler perl-script *
PerlTransHandler +URL_BLOCK
<Files *.html>
AddHandler perl-script *
PerlHandler Embperl
</Files>
<Location "/resources">
Options +Indexes +FollowSymLinks
</Location>
<Location "/images">
# AddHandler perl-script *
# PerlTransHandler URL_BLOCK
</Location>
<Location "/pharmacy/sales">
Deny from All
</Location>
ErrorLog logs/error_log
CustomLog logs/access_log common
</VirtualHost>
~~~~~~~~~~~~``
Here, embperl silently fails (see http://www.mrbrklyn.com and the
localtime command is visable).
the URL_BLOCK works (try http://www.mrbrklyn.com/////index.html)
mod_dir functions
