** Don't try to set a global variable in the same file as a class definition (Profiler.php). Set it in WebStart.php instead.
** In StartProfiler.sample, don't use require_once() to get ProfilerStub.
* Removed the setproctitle() stuff from ProfilerStub, the extension is not maintained and doesn't work with Apache 2.x
* Added an optimisation to wfProfileIn() and wfProfileOut() to reduce the overhead when profiling is not enabled
* Added the ability to configure in StartProfiler.php whether CPU time or wall-clock time is used, avoiding recompilation
* Added the ability to compile extensions. The build process is bootstrapped by running MediaWiki in interpreted mode. Extension setup file inclusions are slightly modified in a way that makes them register themselves for compilation. Then the same LocalSettings.php uses the compiled extension setup file when the compiled binary runs.
* Tested with Cite and ParserFunctions. The code which lets you have an extensions directory in a place other than $IP/../extensions is untested.
* Simplified WebStart.php slightly by using a custom $_SERVER variable to mark compiled mode. It will break if you don't use the supplied server.conf, but that will break a lot of things so don't do that.
* Fixed the core web entry points to include WebStart.php in compiled mode instead of interpreted.
* Made the build directory configurable. This is mostly so that I can grep the source tree without seeing loads of generated C++.
* In server.conf, added a rewrite rule allowing a /wiki/$1 article path.
* Removed server.conf log file location "/dev/stdout", breaks when you switch user
* Disable static content cache, breaks horribly when you set SourceRoot to a directory containing 7GB of files.
* Rewrote the run-server script in PHP, mostly to support the configurable build directory feature.
* Added an option to the run-server script to allow running in interpreted (hphpi) mode.
Adding X-Content-Type-Options: nosniff header in WebStart.php so that it's *always* set, even for alternate entry points and when $wgOut gets disabled or overridden.
Note that this of course doesn't apply to uploaded images and such loaded directly -- the usual caveats still apply.
Have not tested to confirm that this actually protects against sniffing errors -- please test on IE8 and IE9.
* Move autoloader up a little bit so the profiler classes can use it
* Make Profiler into a singleton so it's lazy-constructed, $wgProfiler is now a configuration array (used 'visible' in ProfilerSimpleText as an example of other globals we can move into this array). If $wgProfiler is set to an object, it'll use that for back-compat
* Maintenance: rather than setting up the profiler and then disabling it, just disable it from the start
* Kill $wgProfiling -> now that ProfilerStub overrides profileIn() and profileOut(), it's not needed
* dumpHTML needs some fixes still
* Move them all to includes/profiling/* - If you're using StartProfiler, you'll need to update that
* Make ProfileStub subclass the Profiler rather than duplicating function definitions conditionally
* Removed unused params to wfGetProfilingOutput(), only used in the stub, and they didn't do anything with them
* TODO: Kill $wgProfiling, make $wgProfiler a config array and move the various options to that. Also make into a singleton, rather than global (not much calls it outside of core)
* Fix parsing of the three major entry points (index.php, api.php, load.php) back to PHP 4.4.9. We don't care what happens if you actually try to run these files on old versions, but the entry files need to parse correctly.
* consign /includes/templates/PHP4.php and /includes/templates/NoLocalSettings.php to the fiery pit of hell where they belong.
* Prevent loading of any other files for PHP < 5. WebStart.php was rendered unparseable in PHP 4 by the introduction of try/catch blocks in r85327.
* Die outright with a pretty error message on PHP < 5.2.3 as well as PHP 4. All versions of PHP below that throw parse errors of various sorts.
* Reimplement wfDie() to provide an entry-point-dependent die-with-readable-error-message function (for instance, we want a pretty human-readable page in index.php, something wrapped in CSS/JS /*...*/ comment block in load.php, etc).
* Standardise the appearance of the catastrophic errors thrown at the top of the stack with the ones lower down (exception-within-exception, etc). There isn't really a way to do this without duplication, AFAICT.
* Work around HipHop issue 314 (volatile broken) and issue 308 (no compilation detection) by adding some large and ugly compilation detection code to WebStart.php and doMaintenance.php.
* Provide an MW_COMPILED constant which can be used to detect compiled mode throughout the codebase.
* Introduced wfIsHipHop(), which detects either compiled or interpreted mode. Used this to work around unusual eval() return value in eval.php.
* Work around lack of ini_get() in Maintenance.php, by duplicating wfIsHipHop().
* In Maintenance::shouldExecute(), accept "include" as an inclusion function name, since all kinds of inclusion give this string in HipHop.
* Introduced new class MWInit, which provides some static functions in the pre-autoloader environment.
* Introduced MWInit::compiledPath(), which provides a relative path for invoking a compiled file, and MWInit::interpretedPath(), which provides an absolute path for interpreting a PHP file. Used these new functions in the appropriate places.
* When we are running compiled code, don't include files which would generate duplicate class, function or constant definitions. Documented the new requirements on the contents of Defines.php and UtfNormalDefines.php.
* In HipHop compiled mode, it's not possible to have executable code in the same file as a class definition.
** Moved MimeMagic initialisation to the constructor.
** Moved Namespace.php global variable initialisation to Setup.php.
** Moved MemcachedSessions.php initialisation to the caller in GlobalFunctions.php.
** Moved Sanitizer.php constants and global variables to static class members. Introduced an accessor function for the attribs regex, as a new place to put code formerly at file level.
** Moved Language.php initialisation of $wgLanguageNames to Language::getLanguageNames(). Removed the global variable, marked "private" since forever.
* In two places: don't use error_log() with type=3 to append to a file, HipHop doesn't support it. Use file_put_contents() with FILE_APPEND instead.
* Work around the terrible breakage of class_exists() by using MWInit::classExists() instead in various places. In WebInstaller::getPageByName(), the class_exists() was marked with a fixme comment already, so I replaced it with an autoloader solution.
* Don't set $IP. The entry point already sets it, so there's no point. Users can still set it if they can figure out a way to do it without breaking things.
* Don't include DefaultSettings.php. Doing that is code, not configuration, and it can easily be done in WebStart/Maintenance. Some non-standard entry points in extensions may be broken by this. That's their fault for being non-standard. Backwards compatibility is preserved thanks to require_once().
* Introduce $wgInvalidateCacheOnLocalSettingsChange, which when set, causes $wgCacheEpoch to be updated in the way that it previously was in the default LocalSettings.php.
* Don't set $wgLocalInterwiki to some nonsense value (possibly including spaces and punctuation in the new installer). It should be only for actual interwiki prefixes. Since most wikis don't have them, I set this to false by default and adjusted the referring code to accept this.
* Removed the guard for web invocation with $wgCommandLineMode set. This ancient code is redundant with modern protections in doMaintenance.php.
* In DefaultSettings.php, fixed fold terminator placement near $wgLoadScript
* Add a web entry point guard. That's one piece of code which really is necessary.
* Don't call quickUserCan('edit') unless section edit is enabled
* In DatabasePostgres and DatabaseSqlite: throw an exception on connection error
* In DatabasePostgres: don't send an invalid connection string whenever one of the fields is empty. Use quoting.
* In Database: make the captured PHP error prettier
* Display a descriptive error message when the user navigates to index.php with PHP 4, not a parse error. Check to see if the *.php5 extension works, using file_get_contents().
* The default port number for PostgreSQL is 5432, not blank.
* Better default for $wgDBname
* Wrote a tool to check the integrity of the autoloader class list, fixed some issues that came up.
* Start the autoloader before LocalSettings.php, so that when an extension writer thinks an inefficient one-file special page extension is the way to go, they don't have to use explicit includes to make the class inheritance work. Should continue to work with $IP set in LocalSettings.php as long as $IP is set before extensions are included.
The ob_start() section should preferably be removed from older
LocalSettings.php files.
* Give Content-Length header for HTTP/1.0 clients.
* Partial support for Flash cross-domain-policy filtering. Text entry points should be protected, but uploads are not.
