Apache2 Autoindex Mods/Custom

jmoschetti45 · 11-04-2010, 10:49 PM

I'm trying to modify mod_autoindex.

That in itself isn't too hard, I just copied the source and changed what needed to be changed.

It's loaded in apache as mod_customindex now, and apache sees it and doesn't have a problem with it.

Now, the problem is: How do I get it to index dirs?

If I turn autoindex off on a dir, I get a 403.

Hi,

To stop getting a 403 error for a directory, you need

Code:

Options Indexes

for the DocumentRoot directory, or explicitly set

Code:

Options +Indexes

for that directory.

That still uses the default autoindex, not customindex. How do I force it to use the custom one?

Edit: I think this will clarify it more. I need the standard autoindex for everything but a few dirs, and customindex for a select few dirs.

Hi,

The mod_autoindex directives can be used in a per directory basis either in httpd.cond or through .htaccess.
I don't know what you've changed to create your custom autoindex module, but you should create custom directives in the modified module and use them to do what you're trying to do.

I stripped a bunch of useless stuff out and changed the HTML.

I did change the options directives so they don't overlap with autoindex.

More or less, I think the problem is I'm not sure how the "Options +Indexes" part of the httpd config is handled.

If I enable Options +Indexes, autoindex takes over. If I don't, I get a 403.

I need to know how to "enable" the module for that folder I believe.

Edit: Some code

Code:

if (allow_opts & OPT_INDEXES) {
	int errstatus;
	if ((errstatus = ap_discard_request_body(r)) != OK) {
		return errstatus;
	}
	if (r->filename[strlen(r->filename) - 1] != '/') {
		r->filename = apr_pstrcat(r->pool, r->filename, "/", NULL);
	}
	return index_directory(r, d);
} else {
	ap_log_rerror(APLOG_MARK, APLOG_ERR, 0, r, "Directory index forbidden by Options directive: %s", r->filename);
	return HTTP_FORBIDDEN;
}

That code is the same in autoindex and customindex. I can't change the OPT_INDEXES to anything else or I get the usual "error: 'OPT_INDEXES2' undeclared (first use in this function)" There's no other instance of OPT_INDEXES anywhere else in the file, so I have no idea where I'd have to define a new variable.

Code:

        <Directory /var/www/test/>
                Options Indexes
                MediaIndexOptions MinNameWidth=24 MaxNameWidth=128
                Order allow,deny
                allow from all
        </Directory>

This needs to work without having to recompile apache itself.

Hi,

Does apache refuse to start complaining about MediaIndexOptions?
If not, then the directive is recognized (meaning that it uses your custom autoindex).
If the result is not what you expect it to be, then you should review your changes in the code.

Those directives are properly interpited.

I think the problem has been narrowed down to the fact that autoindex runs before customindex.

I've tried simply compiling a second copy of autoindex with only 2 changes in the HTML to see if it would pull up, and it wont. Is there some way to set the order of the modules loaded? Or am I off on the wrong track?

If I replace mod_autoindex.so with a renamed version of mod_customindex.so it works fine, but then I lose the original entirely.

Hi,

I think that you're indeed on the wrong track.
This has nothing to do with the order modules are loaded, since you use custom directives that are available only in your custom modules. When apache encounters these directives it will use your module to parse the resulting page regardless of the modules order.

FYI apache loads the modules in the order of the LoadModule directives that exist in httpd.conf, so you can load your module before the default autoindex.so, but it's not going to work for the reason explained above.

If you want to customize the resulting html, better take a look here
