Hello,

I am in deep trouble.

I use some of my articles on an external page as described on http://www.s9y.org/206.html

first, all was OK. but:

I changed my installation: The blog is now a shared installation (with symlinks).

so I have:

Code: Select all

+cms-s9y+s9y   (the core-installation)
        +my-blog
        +other-blog
        +external-page

and 1) my external-entries-tpl in my used template is not found and (after copying it to the standard template directory) no article of my choosen category is found!

So, I think, the problem is here:

Code: Select all

    <?php
    // 1: Switch to the Serendipity path
    chdir('../my-blog/');
    // 2: Start the Serendipity API
    include 'serendipity_config.inc.php';
    // 3: Start Smarty templating
    serendipity_smarty_init();

the external pages goes to the right blog-dir, but there the serendipity_config.inc.php is a shared-installation-dummy and includes the serendipity_config.inc.php of ../s9y and then the wrong serendipity_config_local.inc.ph is used: not the one of ../my-blog but the ../s9y! So it wants to use the template of s9y and not my-blog and it wants to read the wrong database

OK, I think I found it:

Code: Select all

if (file_exists($_SERVER['DOCUMENT_ROOT'] . dirname($_SERVER['PHP_SELF']) . '/serendipity_config_local.inc.php')) {
    $local_config = $_SERVER['DOCUMENT_ROOT'] . dirname($_SERVER['PHP_SELF']) . '/serendipity_config_local.inc.php';
} elseif (file_exists($serendipity['serendipityPath'] . '/serendipity_config_local.inc.php')) {
    $local_config = $serendipity['serendipityPath'] . '/serendipity_config_local.inc.php';
} elseif (defined('S9Y_DATA_PATH')) {
    // Shared installation!
    $local_config = S9Y_DATA_PATH . '/serendipity_config_local.inc.php';
} else {
    // Installation fallback
    $local_config = S9Y_INCLUDE_PATH . '/serendipity_config_local.inc.php';
}

The second if (the first elseif) is true, because in /cms-s9y/s9y I have a serendipity_config_local.inc.php. Because I wanted to administrate the whole blog-system with this (e.g. update plugins via Spartacus etc.).

Now, I delete the serendipity_config_local.inc.php there and all works fine, the third if matches now:

Code: Select all

 elseif (defined('S9Y_DATA_PATH')) {
    // Shared installation!

Is there any trouble, when we resort this if-clauses?

When we take the shared installation before the "$serendipity['serendipityPath']"-if?

Hi!

Ah, okay. No problems are expected then. The local config just confuses the shared installs, because shared sources are not meant to be "active".

HTH,

Do you insert it into the CVS?

Hi!

What exactly? I thought no modifications were needed.

in the moment it works with the actual code, because I delete the config-file in the core-installation.

But it would be nice to have the core-installation "active", too.

so it would be fine to resort the if clauses:

not

Code: Select all

elseif (file_exists($serendipity['serendipityPath'] . '/serendipity_config_local.inc.php')) { 
    $local_config = $serendipity['serendipityPath'] . '/serendipity_config_local.inc.php'; 
} elseif (defined('S9Y_DATA_PATH')) { 
    // Shared installation! 
    $local_config = S9Y_DATA_PATH . '/serendipity_config_local.inc.php'; 
}

but

Code: Select all

elseif (defined('S9Y_DATA_PATH')) { 
    // Shared installation! 
    $local_config = S9Y_DATA_PATH . '/serendipity_config_local.inc.php'; 
}

elseif (file_exists($serendipity['serendipityPath'] . '/serendipity_config_local.inc.php')) { 
    $local_config = $serendipity['serendipityPath'] . '/serendipity_config_local.inc.php'; 
}

as I understand you right, this resort would have no negative effect, right?

Hi!

But it would be nice to have the core-installation "active", too.

Ah. Hm, that's currently not on my personal todo-list. The problem is that with your shuffled if-clauses this might break proper installations with symlinked directories and open_basedir restrictions. In case those installations are on a server where a shared installation resorts, this would activate a shared installation without the user wanting this.

So this would require some very intense testing that I currently have no time for. Since it introduces a new feature that was not kept in mind when developing shared installs, I prefer to not break existing things. Hope you can understand that?

Garvin

hm, my installation is one with symlinks and I have open_basedir-restrictions!?

In case those installations are on a server where a shared installation resorts, this would activate a shared installation without the user wanting this.

why should my resort activate a shared installation? This will be activated only when the user generates a personal_config.inc.php in the core-directory!?

The new order of the if-clauses has in my eyes only one effect:

first s9y looks, if it is started by a shared side (and not by the core-installation). If it is not, then it looks if there is a config-file in serendipityPath.

With the actual code it will first look in serendipityPath (where, as you say, normaly is no config-file) and if the user explicit wants to have an active s9y there, then it uses this config-file, even it s9y is started by a shared site, what is bad.

If the user do not want the core-installation active, then there is no config-file there and it should be absolut unimportant, what the order of the if-clauses is. Or?

Hi!

Thanks for the detailed explanation. Seems I misread the patch initially. I now committed your changes.

Best regards,
Garvin
