(proposal) Although the default setting specified in Xdebug's documentation (http://www.xdebug.org/docs/basic) says default_enable is on by default, we should turn it off on Gentoo because Xdebug can be installed accidently as a dependency (e.g. by PHPUnit) and then threatens normal operation of a previously running web server. At least there should be a warning on postinstall because as long as there is no warning, admins may spend hours searching for the cause. I think it would be best to make this a USE flag, deactivate it by default and/or notify the user. Reproducible: Always Steps to Reproduce: 1. emerge xdebug or phpunit (xdebug is a dependency) 2. restart Apache 3. run any erroneous script (like: <?php test(); ?>) Actual Results: Got an orange table showing call stack and variable dumps. (expected behaviour after intended installation of Xdebug according to the official documentation, however this will break many websites accidentally without former warning) Expected Results: The standard PHP inline error message like: "Fatal error: Call to undefined function test() ..." (this deviates from the intended behaviour of an intended installation of Xdebug) Because it breaks a previously working system by accident, I propose to set xdebug.default_enable="0" in /etc/php/apache2-php5/ext/xdebug.ini (change line 44 of both ebuilds to php-ext-base-r1_addtoinifiles "xdebug.default_enable" '"0"'), display a warning on postinstall or make the default setting configurable by a USE flag.
will be fixed in the 2.0.5 ebuild
Disabled by default in 2.0.5. Thanks for reporting!
