keep track of the user's last access. In turn, this allowed me to:
1. Optimize the "Who's online" block. On drupal.org, the "Who's online"
block requires 32 SQL queries. With this patch, only 2 queries are
left (eliminated 30 SQL queries), and one of the two remaining queries
became appr. 20 times faster.
2. Correct the "Last access" column in the user administration overview
table. The presented data was not accurate, which led to the column
being removed. You can now sort users by 'last access'.
- Clean URLs: search/type/keywords e.g. "search/node/drupal release". The search
form is POST submitted, but drupal_gotos to a GET page. This makes it easy to
copy/paste search URLs, and makes the pager a lot cleaner.
- Remember the search keywords when switching between the search tabs. This is
done through the same GET URLs rather than the session, so it does not mess up
between multiple browser tabs.
- Report which keywords were ignored because they were too short.
- #820: Provide search block
- Treat multiple wildcards in a row as one
- permissions menu link updates in a number of modules help
- anchor link fix in distributed auth help
- "my account" link fix in user help
- spelling correction in tracker.module help
- I also changed 'admin/access/perms' to 'admin/access/permissions'.
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).
