Run PHP with -d parameters

[Mechazawa]

Right now the PHPUnit executable is called directly by the application. This means that /usr/bin/env php is implicitly used to execute php. It would be great to have a parameter that allows us to set uptional ini parameters. Such as -d zend_extension=xdebug.so. Since XDebug isn't always loaded in on every system by default and is sometimes only used to get coverage information.

A way of implementing this would be to add an optional parameter and prepending /usr/bin/env php -d foo=bar -d baz=tor to the command. Currently running paratests with -d zend_extension=xdebug.so does not carry over to the subprocesses it spawns.

// Something like this should do the job
$this->addOption('set-ini', 'd', InputOption::VALUE_IS_ARRAY | InputOption::VALUE_OPTIONAL, 
                 'Set php ini params before execution (ex: -d zend_extension=xdebug.so)');`

Something like --load-extension xdebug.so would also be good.

As long as you're using the standard runner, it should be possible (albeit annoying) as a workaround to create a small script that does exec php -dzend_extension=xdebug.so phpunit. You name it phpunit-wrapper (or similar) and get paratest to call it using the --phpunit=path/to/phpunit-wrapper command line option.

Unfortunately, this workaround seems to be broken for the WrapperRunner, which uses a hard-coded phpunit wrapper that can't be changed: https://github.com/brianium/paratest/blob/master@{2016-06-27}/src/ParaTest/Runners/PHPUnit/WrapperRunner.php#L46

BTW, I vote 👎 for --load-extension, because my use case is -dmemory_limit; I'd be good to keep this more generic (the WrapperRunner problem above affects any -d flag, because an actual PHP process is no longer seeing $argv I think...)

I'd appreciate this feature as well.

#361 just got merged into master. Please check if you can use that as a "generic" workaround:

php '-d' 'zend_extension=xdebug.so' bin/paratest -p 4 --coverage-text test/unit --passthru-php="'-d' 'zend_extension=xdebug.so'"

See docs/code-coverage.md (ping #362) for a more in-depth usage example.

@paslandau is right, so I close this issue.
