Re: mbstring

I know this is ugly, but what about making the extensions handle it themselves? Your example of session_pgsql: In the extension init code: ext_enabled = 1; if ( dlsym( NULL, "psql_module_entry" ) == NULL &&

     dlsym( NULL, "_psql_module_entry" ) == NULL )

{

    // print some warning about needing the pgsql extension
    // or pgsql should be loaded before this one in the php.ini
    ext_enabled = 0;

} if ( dlsym( NULL, "session_module_entry" ) == NULL &&

     dlsym( NULL, "_session_module_entry" ) == NULL )

{

    // print some warning about needing the session extension
    // or session should be loaded before this one in the php.ini
    ext_enabled = 0;

} The second call with a underscore is to handle Openbsd and old version of FreeBSD, I think a.out things. I am sure this can be handled differently, but you get the point. Cheers, Brian At 9:19 AM +0900 9/2/02, Yasuo Ohgaki wrote:

We know current module loader is not smart :) As number of modules increases, number of module depends on another increases. Examples are mbstirng/mailparse/exif, session/msession/session_pgsql and bunch of session save handler modules out there, session_pgsql depends of session and pgsql module, etc. (Loading sessoin save handler as module does not work at all, since current module loader isn't take into module dependency at all) I would like to see smart module loader and/or ini parser that can address this issue. PHP crashes easily w/o it. IF statemnet is better than now, but it's not good enough. I don't think this carefully, but here is my idea. Add following member so that get_module() retrive loading weight (we need this so that we can control sub module

                 loading order)

list modules depend on Check if module required is there, raise E_WARNING if module cannot be loaded. Sort modules so that modules are loaded w/o problem. Load modules. This is easy to implement, isn't it? We may better to have smart ini parser, but it may not be required strictly for this purpose. I don't have plan to write this, since I need to modify engine code. I hope Andi or Zeev like this idea for PHP5 :) BTW, I'm +1 for having IF statement in php.ini. -- Yasuo Ohgaki
