Improvements to handling of 'catastrophic' errors, like unsupported PHP versions, no MySQL functions, no LocalSettings, etc. * 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. Comment: In most places where you might want to use this new variant of wfDie(), you can throw an exception instead. Exceptions already have the infrastructure for formatting error messages in various ways depending on the entry point. If there's some problem with that infrastructure, then it should be fixed rather than duplicated. The old uses of wfDie() are just a shortcut for "echo $msg;die(-1);", they reflect Brion's disgust at PHP when he found out that die($msg) doesn't do that. See r12660. I removed most instances from the core in r14631 in favour of exceptions. _______________________________________________ MediaWiki-CodeReview mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/mediawiki-codereview
