Drupal currently executes functions in include files. This is very
annoying if you want to include files from external scripts such as
update scripts or other scripts that want to use Drupal as a framework.


Offending files are:


database.inc:
db_set_active();


session.inc:
session_set_save_handler("sess_open", "sess_close", "sess_read",
"sess_write", "sess_destroy", "sess_gc");
session_start();


common.inc:
A bunch of stuff at the bottom.


All this should be moved into a start.inc file.

I haven't done this recently, but back in 4.4 era I attempted something
similar to this for the install api.


A _lot_ of modifications were required to be able to use (for instance)
the theme api without needing to have a database connection active.

It's definately not a simple problem.


For instance.. the db connection needs to be started during bootstrap,
and during normal execution.


I think the better idea is to include a DRUPAL_INIT constant we can
check before executing the function. (or a DRUPAL_NO_INIT .. i'm not
picky).

Here's an old patch by me that illustrates what I want to do.

Instead of putting the stuff into index.php, alternative file names
need to be found.

Well, I have written something to address the issue.


Now you can include everything to your hearts content just include
init.inc as well and do an appropriate drupal_bootstrap.


Alas, ATM database and bootstrap is very interwined. This
interdependency could be obliterated if we'd not use
variable_get('dev_query') in database.*.inc.


cvs diff -u -N -F^f against cvs.drupal.org as CVSROOT failed to include
to include the two new files, so I'll include them as followups.

Following advice from darix I have now created one patch. Still, I'd
like to know how could I do this with cvs.

Steef found that I had $$ in settings.php.


He also asked what's this good for. Several things, but most advantages
come when you use only parts of Drupal. If you want use, say, only our
forms functions then now you can include('common.inc'); without side
effects. If you need the database layer, you do a include('init.inc')
and call drupal_bootstrap('database')

The database layer is now totally independent of other parts of Drupal.

A very stupid bug related to variable init is fixed and I am sync'd to
HEAD, so timer_init('page') is called.
