9cdfe82c56cd Major underlying changes to namespace handling. Each namespace is handled by its own class which extends Namespace_Default. Much greater customization/pluggability potential, at the possible expense of some code reusing (though code reusing has been avoided thus far). Also a bit better handling of page passwords [SECURITY].

This should only be used very early on to indicate very severe errors, or if the site may be under attack (like if the DBAL detects a malicious query).

323c4cd1aa37 Made some more changes to the way namespaces are handled, for optimization purposes. This is a bit of a structural reorganization: $paths->pages is obsoleted in its entirety; calculating page existence and metadata is now the job of the Namespace_* backend class. There are many things in PageProcessor that should be reorganized, and page actions in general should really be rethought. This is probably the beginning of a long process that will be taking place over the course of the betas.

This is a bit of a structural reorganization: $paths->pages is obsoleted in its entirety; calculating page existence and metadata is now the job of the Namespace_* backend class. There are many things in PageProcessor that should be reorganized, and page actions in general should really be rethought. This is probably the beginning of a long process that will be taking place over the course of the betas.

acb7e23b6ffa Massive commit with various changes. Added user ranks system (no admin interface yet) and ability for users to have custom user titles. Made cron framework accept fractions of hours through floating-point intervals. Modifed ACL editor to use miniPrompt framework for close confirmation box. Made avatar system use a special page as opposed to fetching the files directly for caching reasons.

323c4cd1aa37 Made some more changes to the way namespaces are handled, for optimization purposes. This is a bit of a structural reorganization: $paths->pages is obsoleted in its entirety; calculating page existence and metadata is now the job of the Namespace_* backend class. There are many things in PageProcessor that should be reorganized, and page actions in general should really be rethought. This is probably the beginning of a long process that will be taking place over the course of the betas.
