Administration tools

Expires rows from the session table older than a certain time.

Background

By default, Drupal ships with a session expiration time of just over 23 days, using this directive in settings.php:

ini_set('session.cookie_lifetime',  2000000);

However, for this to work automatically, it requires PHP's garbage collection to be configured correctly.

Since some distributions, e.g. Debian and Ubuntu do not ship with PHP defaults that triggers PHP garbage collection, there is a need to also set the following:

ini_set('session.gc_probability', 1);
ini_set('session.gc_divisor', 100);

This will work, but has some drawbacks:

• It will be triggered at some random time, rather than at a predictable time.
• It could slow the response for the unlucky user who happens to trigger it.

So, on sites with a distribution that is not setup as above, or on really busy sites, the sessions table can grow to be very large, and that can cause slow accesses to it, as well as slow writes due to locking, leading to performance bottlenecks.

This module makes the q=admin/user/access ("Access control") page easier to use by sorting the permission table so that rows belonging to a certain content-type are grouped together.

Node Hierarchy allows nodes to be children of other nodes creating a tree-like hierarchy of content. The module offers:

• 1-Click creation of hierarchical menus
• Hierarchical breadcrumbs
• Automatic hierarchical urls using Pathauto (and token module)
  (eg: q=aboutus/history/beginning).
• Automatic creation of hierarchical menus if desired.
• Optional Views integration.
• Optional Node Access integration.

Edit term provides links on taxonomy listing pages to directly edit taxonomy terms.

This makes it easier to immediately edit term name, synonyms, description, and weight for the term you are viewing without navigating through your site's administrative back end.

On the term edit page, you also have the new ability to set an URL-alias for the term directly, and create and position a menu item - the same way as can be done for nodes. See illustration.

Once changes are made, you are returned to the listing page from which you started, cutting normal term management procedure down from a dozen clicks to just two.
