xdebug is always activated→major performance impact on the website

[ewasser]

In the current postinstallation file (Debian 8 / php7.0-xdebug 2.5.1-1~dotdeb+8.1) xdebug is always activated regardless if it's a fresh installation or an upgrade from a previous one:

Here's the file /var/lib/dpkg/info/php7.0-xdebug.postinst:

#!/bin/sh
set -e
# Automatically added by dh_php
for conf in xdebug; do
    dpkg-maintscript-helper rm_conffile /etc/php/mods-available/${conf}.ini -- "$@"
done

if [ -e /usr/lib/php/php-maintscript-helper ] ; then
    . /usr/lib/php/php-maintscript-helper

    for version in 7.0 ; do
        for conf in xdebug ; do
            php_invoke enmod $version ALL $conf || exit $?
        done
    done
else
    for conf in xdebug ; do
        phpenmod $conf
    done
fi

The module will always be activated. This is not a good behaviour. An upgrade shouldn't change the current configuration of a component at all.

I know that other modules are doing php_invoke enmod/phpenmod too but enabling the xdebug modul has a major performance impact on a website, so it's a bad thing to do. ;-)
