epriestley b9a1260ef5 Improve top-level fatal exception handling in PHP 7+ ... Summary: Depends on D20137. Ref T13250. Ref T12101. In versions of PHP beyond 7, various engine errors are gradually changing from internal fatals or internal errors to `Throwables`, a superclass of `Exception`. This is generally a good change, but code written against PHP 5.x before `Throwable` was introduced may not catch these errors, even when the code is intended to be a top-level exception handler. (The double-catch pattern here and elsewhere is because `Throwable` does not exist in older PHP, so `catch (Throwable $ex)` catches nothing. The `Exception $ex` clause catches everything in old PHP, the `Throwable $ex` clause catches everything in newer PHP.) Generalize some `Exception` into `Throwable`. Test Plan: - Added a bogus function call to the rendering stack. - Before change: got a blank page. - After change: nice exception page. {F6205012} Reviewers: amckinley Reviewed By: amckinley Maniphest Tasks: T13250, T12101 Differential Revision: https://secure.phabricator.com/D20138		2019-02-11 15:05:15 -08:00
