[TwigBundle] Extract output buffer cleaning to methoded1a6c2
[TwigBundle] Do not clean output buffering below initial level Discussion ---------- [TwigBundle] Do not clean output buffering below initial level This resulted in issues with PHPUnit 3.6, which will buffer all output and clean them in the end. Since we cleaned their buffer, the subsequent clean would raise a warning. This is documented in [issue 390](https://github.com/sebastianbergmann/phpunit/issues/390) of the PHPUnit tracker. Closes #2531. This also affects FOSRestBundle's ExceptionController /cc @lsmith. --------------------------------------------------------------------------- by fabpot at 2011/11/11 07:33:24 -0800 I have a similar fix locally but I have not merged it yet as it looks a bit dirty (but I've not a better idea yet). Anyway, your PR is better than mine as you've added some unit tests already.
