- Converted the Bluemarine theme from XTemplate to PHPTemplate.
- Moved the the Pushbutton theme and the Xtemplate engine to the contributions repository.
Drupal's existing caching mechanism doesn't perform well on highly dynamic websites in which the cache is flushed frequently. One example is a site that is under attack by a spambot that is posting spam comments every few seconds, causing all cached pages to be flushed every few seconds. Loose caching immediately flushes the cache only for specific users who have modified cached data (whether or not they are logged in), delaying the flushing of data for other users by several minutes.
(I rewrote the help text a bit and made minor changes to the code comments.)
There are 5 main functions that modules may now utilize to handle images:
* image_get_info() - this function checks a file. If it exists and is a valid image file, it will return an array containing things like the pixel dimensions of the image, plus the 'type' and common extension.
* image_scale - resizes a given image to fit within a given width / height dimensions, while maintaining aspect ratio (not distorting the image). This function can be used to generate thumbnails, or ensure a maximum resolution, etc.
* image_resize - similar to image_scale (but will not respect aspect ratio - may well distort the image).
* image_rotate - rotate an image by X degrees
* image_crop - crops an image to a given rectangle (defined as top-left x/y coordinates plus a width & height of the rectangle).
Contribution modules will now be able to rely on these base manipulation functions to offer additional functionality (such as image nodes, photo galleries, advanced image manipulation, etc).
* Less logic in theme code.
* Encourages use of the menu system.
* Easier to find where a title or breadcrumb comes from in other people's code because there are less places to look. Look in menu and then grep for the appropriate set function. Looking for calls to theme_page() is hard because there are too many of them.
* Very slightly more efficient.
changes are:
1. Simplified the statistics pages: there are less pages and on the
remaining pages there is a lot less visual clutter (less columns and
better presentation).
2. Reorganized the 'administer - logs' menu: flattened the menu structure
and removed a number of links.
3. Improved performance. Most statistics pages used about 160 slow SQL
queries which made the statistics pages fairly unusable on my system.
The new pages use at least 10 times less SQL queries and render much
faster. They are actually usable.
4. There is now a 'track'-tab on node pages, and a second subtrab on the
user accounts 'track'-tab for people with the 'access statistics'
permission. They can be used to resp. track the node and the user.
This makes the statistics more accessible.
5. Changed the way watchdog messages are filtered. This makes it easier
to introduce new watchdog types.
6. Reworked the statistics module's permissions.
7. Less code: 223 insertions(+), 343 deletions(-).
8. Fixed several glitches: for example, the statistics pages sorted the
'Name' column by user ID instead of by name. Unfortunately, it is
too difficult to backport these to DRUPAL-4-5.
TODO:
1. Review the statistics modules help pages.
2. Help fine-tune the interfaces/views.
NOTES:
1. You'll want to run update.php.
