- 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 'previous topic' / 'next topic' links skipped topic without comments (changed one inner join back to a left join).
+ The default order setting in admin/settings/forum had no effect.
+ The 'first new topic' link jumped to the first unread topic ever instead of the first unread topic since NODE_NEW_LIMIT.
+ This also removes the unused $offset param from theme_forum_display and theme_forum_topic_list, so any themes using these functions should be updated (i checked the core themes but none of them used these functions).
Here's a new patch that unifies the node/52 and book/view/52 paths for nodes. It involves a small change to hook_view(), which is discussed first:
Currently hook_view() expects node modules to return a themed node. However, each module does this the same way; they modify $node as necessary, then call theme('node', $node) and return the result. We can refactor this so that the calling function node_view() calls theme('node') instead. By doing this, it becomes possible for hook_nodeapi('view') to be called after hook_view() where the node contents are filtered, and before theme('node') where the body is enclosed in other HTML. This way the book module can insert its navigation into the body right before the theming.
Advantages of this refactoring:
- I can use it for book.module to remove the extra viewing path.
- The function of hook_nodeapi('view') becomes more like hook_view(), as neither will expect a return value.
- We more closely follow the flow of other nodeapi calls, which usually directly follow their corresponding specific node type hooks (instead of preceding them).
- The attachment.module people could use it to append their attachments in a list after the node.
- Gabor could use it instead of his filter perversion for his "articles in a series" module.
- A little less code in each view hook.
- The content hook is no longer needed, so that means even less code.
Disadvantages:
- Any modules written to use nodeapi('view') could be affected (but these would all be post-4.4 modules).
- Implementations of hook_view() would need to be updated (but return values would be ignored, so most would work without updates anyway).
Now the patch takes advantage of this API shift to inject its navigation at the end of all book nodes, regardless of the viewing path. In fact, since the paths become identical, I've removed the book/view handler entirely. We should probably provide an .htaccess rewrite for this (one is still needed for node/view/nn anyway). At the same time, there is a check in book_block() that shows the block appropriately on these pages.
* 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').
CHANGES
-------
+ Introduced tabs. First, we extended the menu system to support tabs. Next, a tab was added for every link that was (1) an administrative action other than the implicit 'view' (2) relevant to that particular page only. This is illustrated by the fact that all tabs are verbs and that clicking a page's tab leads you to a subpage of that page.
+ Flattened the administration menu. The tabs helped simplify the navigation menu as I could separate 'actions' from 'navigation'. In addition, I removed the 'administer > configuration'-menu, renamed 'blocks' to 'sidebars' which I hope is a bit more descriptive, and made a couple more changes. Earlier, we already renamed 'taxonomy' to 'categorization' and we move 'statistics' under 'logs'.
+ Grouped settings. All settings have been grouped under 'administer > settings'.
TODO
----
+ Update core themes: only Xtemplate default supports tabs and even those look ugly. Need help.
+ Update contributed modules. The menu() hook changed drastically. Updating your code adhere the new menu() function should be 90% of the work. Moreover, ensure that your modue's admin links are still valid and that URLs to node get updated to the new scheme ('node/view/x' -> 'node/x').
administrators will be able to define a custom 403 page, just as they
can define 404 pages now.
This needs to be documented in the "Changes since / migrating to ..."
pages.
+ only adds an optional parameter to url() and l(), so individual links
can be set to be absolute
+ modifies drupal_goto() to accept the parameters of url() without the
$absolute parameter, so cleaner invocations can be used
+ rework of some code in node_feed, making it much better to look at
(the current code uses foreach with an immediate brake to get the first
key of the associative array, geeeeez)
+ added xml:base to the rss tag generated by node_feed()
+ set all user mail URLs to be absolute
+ fix a small fragmented URL in user.module
easier to understand 'new' links. The 'new' links are clickable both
at the forum overview (to get to the new forum topics) and at the topic
overview (to get to the new comments).
+ removes the lots of pagers and indirect pager themeing
+ add the theme_pager() function, which should be called as
theme("pager", ...) to get a pager.
Phase 2 of the menu system integration project. This unifies the interface
used by admin and non-admin pages, and deprecates the _page hook in favor of
explicit callbacks from menu(). Breadcrumbs, titles, and help text go away
as a result of this patch; they will return in the phase 3 patch, printed
by the theme.
- Improvement: removed a left-over from Drupal 4.2.0 (dead code).
- Improvement: replaced hard-coded XHTML around the XML icons with class="xml-icon".
- Improvement: removed the custom navigation menus shown at the top of the "user information page" and integrated them in the new navigation block. The "my account" link in the navigation menu will unfold. Also removed the "delete account" link/functionality (for now).
- Improvement: fix for "magic quotes" settings. Patch by Steven. I also removed check_php_settings().
- Improvement: block themability improvements. Modified patch from Ax and Steve/CodeMonkeyX.
- Fixed bug #2617: editing user information does not work. Patch by Kjartan.
- comment.module: fixed an ambigous 'timestamp' query
- forum.module: prev/next links no longer excerpt from the title+body in
their title attribute. they now excerpt from only their title. this is
more consistent with rest of drupal, and GROUP BY on node.body which
isn't appreciated by MSSQL. also replaced some '' with NULL which caused
errors in MSSQL
- statistics.module: replaced a USING join with a standard ON join. USING
is not as widely supported, and functionally equivalent.
- Fixed bug #3642: removed duplicate settings from user page. Patch #14 by Moshe.
- Fixed bug #3503: added 'forum topic' link to the 'create content' menu. Patch
by Gobar. I think this might be more intuitive and consistent code-wise; I don't
want to introduce small hacks.
- Cache improvement: small cache improvement to prevent SQL errors. Patch by
Jeremy.
- Made sure the 'Topic' title is only shown above the topics, not the icons.
- Automatically shorten the username when it is too long. I implemented this
as part of format_name() and could therefore nuke some code in the
statistics module. This is change is somewhat experimental and I'm willing
to revert or change this if a number of people aren't too happy with this
behavior.
- Left align the dates and authors: makes it easier/faster to scan.
- Made the little tablesort arrows clickable.
PostgreSQL and MSSQL database scheme as well.
- Made sure the update script updates the correct tables when database
prefixing is enabled. Patch by Bart Jansens.
- Improved the breadcrumb navigation of the book and the forum module as per
Keith Instone's suggestions.
- Updated page titles (or block titles) and links to match. Suggested by
Keith Instone.
- Added missing 'thread' field to the comment table of the MySQL database scheme.
Fixes bug #2590.
Wittens.
- Renamed some column titles in the forum module as per Moshe's suggestion.
- Introduced a 'more-link' class to position the 'more' links. Removed
hard-coded markup from the modules.
- Fixed bug in import module: the theme functions called a non-existing
function.
2) Beautified the forum module views; rewritten to use the table() rendering functions, X HTML-ified the emitted code, added additional CSS tags, and removed hard-coded markup. This improves themeabality; it should be able to mimic the view and color scheme of, say, http://www.phpbb.com/.
3) Reorganized forms and links (interactive elements) to improve usability. Also ensured that the link names and page titles match.
4) Temporary removed container functionality: this simplified the work and eliminated some usability issues.
- Improvement: some small changes to the user module to ease translation and to make things slightly more consistent. This should be a better alternative for patch #54.
- Improvement: increase the maxlength of the node title. This should fix bug #2018 and #2176.
- Improvement: renamed some theme functions of the forum module for sake of consistency/readability. Patch #2 by Kristjan.
- Improvement: usability improvements to the Xtemplate theme. Patch #3 by Kristjan.
- Improvement: CSS'ified the book module pages. Patch #3 by Al. (I simplified the "l
ocation" part. Al's approach gave you a bit more power but I'm not sure anyone wants
to change that. Besides, this will change as soon we integrate the menu system so I kept it easy for now.)
- Fixed the "blog it" image size. Patch #49 by Al.
- Some SQL performance improvements to the forum module. This should also be more PostgreSQL safe. Patch by me.
mysql> SELECT n.nid, n.created AS timestamp, u.name AS name, u.uid AS uid FROM forum f, node n LEFT JOIN users u ON n.uid = u.uid WHERE f.tid = 2 AND n.nid = f.nid AND n.type = 'forum' AND n.status = 1 ORDER BY timestamp DESC LIMIT 1, 0;
==> 0.63 sec
changed to:
