The beginnings of HipHop compiled mode support. It works now for parser cache hits. * 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. Comment: Note that r87748 restores the original version of the require_once line in UtfNormalUtil.php (without the MWInit::compiledPath call added here which caused it to simply break 100% on the generator, test, and benchmark code which does not depend on the rest of MediaWiki) -- the line had been moved to Setup.php in r85944 which still left all the UtfNormal scripts broken (bug 28864). This doesn't seem to have any problems with regular MediaWiki -- as the file is already now included from Setup.php -- but it might have some effect on the HipHop builds, untested. _______________________________________________ MediaWiki-CodeReview mailing list mediawiki-coderev...@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/mediawiki-codereview
