* 2.1: [Yaml] fixed default value Added Yaml\Dumper::setIndentation() method to allow a custom indentation level of nested nodes. added a way to enable/disable object support when parsing/dumping added a way to enable/disable PHP support when parsing a YAML input via Yaml::parse() fixed CS [Process] Fix docblocks, remove `return` from `PhpProcess#start()` as parent returns nothing, cleaned up `ExecutableFinder` fixes a bug when output/error output contains a % character [Console] fixed input bug when the value of an option is empty (closes #6649, closes #6689) [Profiler] [Redis] Fix sort of profiler rows. Fix version_compare() calls for PHP 5.5. Removed underscores from test method names to be consistent with other components. [Process] In edge cases `getcwd()` can return `false`, then `proc_open()` should get `null` to use default value (the working dir of the current PHP process) Fix version_compare() calls for PHP 5.5. Handle the deprecation of IntlDateFormatter::setTimeZoneId() in PHP 5.5. removed the .gitattributes files (closes #6605, reverts #5674) [HttpKernel] Clarify misleading comment in ExceptionListener Conflicts: src/Symfony/Bundle/WebProfilerBundle/Resources/views/Profiler/toolbar_style.html.twig src/Symfony/Component/Form/Tests/Extension/Core/Type/DateTimeTypeTest.php src/Symfony/Component/Form/Tests/Extension/Core/Type/TimeTypeTest.php src/Symfony/Component/Form/Tests/Util/PropertyPathTest.php src/Symfony/Component/HttpKernel/Profiler/RedisProfilerStorage.php src/Symfony/Component/Process/Process.php |

Process Component
Process executes commands in sub-processes.
In this example, we run a simple directory listing and get the result back:
use Symfony\Component\Process\Process;
$process = new Process('ls -lsa');
$process->setTimeout(3600);
$process->run();
if (!$process->isSuccessful()) {
throw new RuntimeException($process->getErrorOutput());
}
print $process->getOutput();
You can think that this is easy to achieve with plain PHP but it's not especially if you want to take care of the subtle differences between the different platforms.
And if you want to be able to get some feedback in real-time, just pass an
anonymous function to the run()
method and you will get the output buffer
as it becomes available:
use Symfony\Component\Process\Process;
$process = new Process('ls -lsa');
$process->run(function ($type, $buffer) {
if ('err' === $type) {
echo 'ERR > '.$buffer;
} else {
echo 'OUT > '.$buffer;
}
});
That's great if you want to execute a long running command (like rsync-ing files to a remote server) and give feedback to the user in real-time.
Resources
You can run the unit tests with the following command:
$ cd path/to/Symfony/Component/XXX/
$ composer.phar install --dev
$ phpunit
