et al. Can you say 'registry'? Drupal now maintains an internal registry of
all functions or classes in the system, allowing it to lazy-load code files as
needed (reducing the amount of code that must be parsed on each request). The
list of included files is cached per menu callback for subsequent loading by
the menu router. This way, a given page request will have all the code it needs
but little else, minimizing time spent parsing unneeded code.
- possible timeouts with installing/enabling lots of modules at once in core
- enable install profiles to have more modules without fear of timeouts on install
- bootstrap Drupal before each module load, so previously enabled modules are bootstrapped
- let modules run their hook_requirements() (although actually calling them will be possibly fixed in another patch)
"This function is called in one place, so it can be rolled into the calling function. The return value isn't used so we can remove handling of it. This is executed for every non-cached page view, so the smaller code should save a smallish ammount of memory and time."
+ Make bootstrap functionality work with HEAD.
+ Move functions into bootstrap.inc so that statistics_exit() works for cached pages. (Does this close any issues?)
* There are only two throttle levels instead of 5, namely 'enabled' and 'disabled'. This makes it a _lot_ easier to predict when the throttle will kick in. However, if you maintain a module that is throttle-aware, it needs to be updated!
* The throttle mechanism now uses the current number of anonymous users or the current number of authenticated users to kick in. This is a _lot_ more intuitive than the old throttle mechanism.
* The throttle block has been removed -- you can now use the "Who's online" block to determine the good throttle settings.
* Most of the documentation has been removed because it was deprecated.
* It's less code!
Modules can be stored anywhere, as there is now a set of functions called module_get_filename, and module_set_filename .. which allow system_listing and module_list to specify the locations of the files.
A new function module_load_all() replaces the hardcoded includes in module_init, and loads all modules which have been enabled, using module_load.
module_listing no longer includes files itself, instead it just keeps the listing (and sets the filenames).
This patch is a requirement for the multisite configuration patch, as overriding modules are currently being loaded due to the only protection of loading them is include_once.
To do this cleanly, I reorganised some bits of system.module: there is now a generic handler available for simple variable-get/set based configuration pages. Look at filter_admin() or system_view() for example usage.
(based on the patch by Goba)
- Modules and themes now use the same functions to find and administer
files.
- Modules can now be placed in sub-directories.
- Theme descriptions can no longer be edited. This will be handled by
Dries' theme_conf patch.
- Update required to keep old modules enabled.
+ Blocks are not longer called if not rendered: major performance
improvement.
+ Fixed some bugs (preview option was broken, path option was broken).
+ Removed "ascii"-type blocks.
+ Added permission to for "PHP blocks"
+ ...
NOTES:
+ You'll want to run "update.php":
ALTER TABLE blocks DROP remove;
ALTER TABLE blocks DROP name;
+ You'll want to update your custom modules as well as the modules in
the contrib repository. Block function should now read:
function *_block($op = "list", $delta = 0) {
if ($op == "list") {
return array of block infos
}
else {
return subject and content of $delta block
}
}
- fixed comment flat list view missing 1 comment.
- changed update.php around a bit.
* security check isn't in effect if the db hasn't been updated.
* instructions re-organized.
* fixed some minor updates.
- updated database.mysql done by UnConeD.
- changelog update.
Committing Changes by Moshe Weitzman:
- admin_user_account(), user_edit(), and user_view() no longer have any
hard code for authentication modules. instead authentication modules
implement the _user hook.
- fixed a couple 'help' typos.
- linked the 'REGISTER' text in the login block to the register page.
this page now advertises DA better if site employs DA.
- admins may now edit everything about a user account (was a feature
request).
- user #1 may now login immediately, in addition to receiving his
password via email.
Other changes:
- modules and themes are now enabled/disabled in the administrative /
settings / modules | themes pages. Requires SQL update and things must
be enabled before your site returns to normal. TODO: enable all
functionality. (For now just do UPDATE system SET status = 1;)
- removed $themes from conf.php.
- added a $theme->system() function where theme can specify settings.
All themes in the Drupal CVS have been updated to use this.
- added _system hook to modules. TODO: update modules to use this.
- changed strange use of sprintf to the usual strtr. The disadvantage of
sprintf is that it requires translations to keep the string order,
which may not be possible in all languages.
- an invalid/nonexisting theme in a user profile will now fallback to the
BaseTheme instead of crashing.
