* Fix a bug which would cause the "configure" link for styles to be broken.
* Fix a bug with using drupal_get_filename for theme engines. Although this is not called anywhere in core, we should still fix it for contrib. (i.e. themes that may want to manually invoke a theme engine to create a hybrid theme)
* Correct an inaccurate comment in theme.inc
* Populate the default primary links with an "edit primary links" link for consistency with the secondary links
* remove some unnecessary variables in the theme administration which had misleading and confusing names
* replace time-consuming foreach when rendering theme admin page with a more efficient array_key_exists
* usability: rather than completely removing the search box checkbox when search.module is disabled, simply disable it. (UI elements shouldn't appear/disappear.)
- 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).
+ throttle module: flush cache when the throttle enables/disables
+ throttle module: prevent throttle being enabled by 0 users or guests when disabled
+ system module: remove requirement for statistics.module
+ block module: update help text to reflect access log is no longer required
+ statistics module: throttle is now enabled/disabled, not using levels 0-5
Upload.module
- Fixing a bug caused by the PHP5 patches.
Beware: PHP4's array_merge() will silently accept objects and convert them to arrays. We should not depend on this behaviour in the future.
File.inc / file-using modules:
- Removing the constant FILE_SEPARATOR: forward slashes work fine on Windows, and it was being used incorrectly as an URL separator sometimes.
- Adding @ to mkdir and chmod to supress ugly PHP errors. They are already reported with drupal_set_message().
- Fixing default for variable 'file_directory_temp'.
- Clarifying the help tip for 'file_directory_temp' in admin > settings.
- Fixed separate styles: added theme_get_styles() and the xtemplate {styles} tag to make sure stylesheets get included in the right order (drupal-specific, template-specific, style-specific).
- Fixing missing class on screenshots.
- Renamed drupal_get_theme_setting() and drupal_get_theme_settings() to theme_get_setting() and theme_get_settings().
Here's an overview of the changes:
1) Multiple Input formats: they are complete filter configurations (what filters to use, in what order and with which settings). Input formats are admin-definable, and usage of them is role-dependant. For example, you can set it up so that regular users can only use limited HTML, while admins can free HTML without any tag limitations.
The input format can be chosen per content item (nodes, comments, blocks, ...) when you add/edit them. If only a single format is available, there is no choice, and nothing changes with before.
The default install (and the upgrade) contains a basic set of formats which should satisfy the average user's needs.
2) Filters have toggles
Because now you might want to enable a filter only on some input formats, an explicit toggle is provided by the filter system. Modules do not need to worry about it and filters that still have their own on/off switch should get rid of it.
3) Multiple filters per module
This was necessary to accomodate the next change, and it's also a logical extension of the filter system.
4) Embedded PHP is now a filter
Thanks to the multiple input formats, I was able to move the 'embedded PHP' feature from block.module, page.module and book.module into a simple filter which executes PHP code. This filter is part of filter.module, and by default there is an input format 'PHP', restricted to the administrator only, which contains this filter.
This change means that block.module now passes custom block contents through the filter system.
As well as from reducing code duplication and avoiding two type selectors for page/book nodes, you can now combine PHP code with other filters.
5) User-supplied PHP code now requires <?php ?> tags.
This is required for teasers to work with PHP code. Because PHP evaluation is now just another step in the filter process, we can't do this. Also, because teasers are generated before filtering, this would result in errors when the teaser generation would cut off a piece of PHP code.
Also, regular PHP syntax explicitly includes the <?php ?> tags for PHP files, so it makes sense to use the same convention for embedded PHP in Drupal.
6) Filter caching was added.
Benchmarking shows that even for a simple setup (basic html filtering + legacy URL rewriting), filtercache can offer speedups. Unlike the old filtercache, this uses the normal cache table.
7) Filtertips were moved from help into a hook_filter_tips(). This was required to accomodate the fact that there are multiple filters per module, and that filter settings are format dependant. Shoehorning filter tips into _help was ugly and silly. The display of the filter tips is done through the input format selector, so filter_tips_short() no longer exists.
8) A more intelligent linebreak convertor was added, which doesn't stop working if you use block-level tags and which adds <p> tags.
