- Patch #10308 by ccourtne: performance improvements: comment statistics are now cached in a new SQL table which significantly improves performance of the forum block and the forum pages. These pages are about 3 times faster now!
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.
+ the confirmation before deleting a comment was missing a check_output.
+ after editing a comment, two pages were shown (two calls to theme('page',..)), replaced this by a drupal_goto.
* improves the doxygentation and help text.
* deletes comment_admin and comment_page; using proper callbacks instead.
* related/modified callbacks/menus/functions were tweaked to not use arg() at all.
* the "settings" subtab was weighted to -10 so it'd appear first (in prep of JonBob's local default).
* moderation pages weren't properly showing defined votes or thresholds; fixed.
* when moderation votes or thresholds didn't exist, no error stating as such was shown; fixed.
* we show "submit votes" on the moderation votes page only when votes actually exist.
* fixes the (broken in CVS) comment/reply and comment/edit features.
* fixes the (broken in CVS) "save settings" for comment view options and comment moderation.
In addition I:
* fixed a couple warnings introduced by Morbus' patch.
* fixed a couple translation bugs.
* fixed comment_node_url().
I also found that:
* the collapsed comment views (i.e. 'threaded list - collapsed) are broken.
forms using the $required argument of the form_ functions.
- Replaced all Optional's and Required's from the taxonomy forms with proper
use of the form_ functions.
Please check your contributed modules too!
* The _validate hook and the _nodeapi('validate') hook of the node API (1) no longer take an 'error' parameter and (2) should no longer return an error array. To set an error, call form_set_error().
* The _form hook of the node module no longer takes a form hook and should not worry about displaying errors. Ditto for _nodeapi('form_post') and _nodeapi('form_pre').
