Disabling xdebug when running composer

Question

When running composer diagnose, I get the following error :

The xdebug extension is loaded, this can slow down Composer a little. Disablin

I don’t think there is an option to configure PHP so it can load different configurations according to the targeted script. At least, not without duplicating .ini files...

However, you can add thoses options when running composer with php:

php -n -d extension=needed_ext.so composer.phar

-n will tell PHP to ignore any php.ini. This will prevent xdebug from loading for this very command.

-d options permits you to add any option you want (for exemple, activate needed_ext.so). You can use multiple -d options. Of course, this is optional, you might not need it.

Then you can create an alias, to make it sugary again.

A typical solution (because composer needs json):

php -n -d extension=json.so composer.phar

greg0ire > my solution, based on that:

#!/bin/bash
options=$(ls -1 /usr/lib64/php/modules| \

    grep --invert-match xdebug| \

    # remove problematic extensions
    egrep --invert-match 'mysql|wddx|pgsql'| \

    sed --expression 's/\(.*\)/ --define extension=\1/'| \

    # join everything together back in one big line
    tr --delete '\n'
)

# build the final command line
php --no-php-ini $options ~/bin/composer $*

alias composer=/path/to/bash/script.sh

It looks ugly (I tried and failed to do that with xargs), but works… I had to disable some extensions though, otherwise I get the following warnings:
