…adFromProcess` (fritzmg)This PR was merged into the 5.4 branch.Discussion----------[Console] Suppress `proc_open` errors within `Terminal::readFromProcess`| Q             | A| ------------- | ---| Branch?       | 5.4| Bug fix?      | yes| New feature?  | no| Deprecations? | no| Issues        || License       | MITWhen instantiating `SymfonyStyle` in a command it will try to determine the maximum width of the current console interface.https://github.com/symfony/symfony/blob/6687e4ea35f45ebd73fb0315938103628cfb13a0/src/Symfony/Component/Console/Style/SymfonyStyle.php#L53This will execute `stty -a | grep columns` down the line. Access to `stty` might be disallowed however, resulting in the following error:```ErrorException: Warning: proc_open(): Exec failed: Permission denied#16 /vendor/symfony/console/Terminal.php(220): Symfony\Component\Console\Terminal::readFromProcess#15 /vendor/symfony/console/Terminal.php(204): Symfony\Component\Console\Terminal::getSttyColumns#14 /vendor/symfony/console/Terminal.php(170): Symfony\Component\Console\Terminal::initDimensionsUsingStty#13 /vendor/symfony/console/Terminal.php(153): Symfony\Component\Console\Terminal::initDimensions#12 /vendor/symfony/console/Terminal.php(94): Symfony\Component\Console\Terminal::getWidth#11 /vendor/symfony/console/Style/SymfonyStyle.php(55): Symfony\Component\Console\Style\SymfonyStyle::__construct#10 /vendor/symfony/messenger/Command/ConsumeMessagesCommand.php(136): Symfony\Component\Messenger\Command\ConsumeMessagesCommand::interact#9 /vendor/symfony/console/Command/Command.php(311): Symfony\Component\Console\Command\Command::run```(Stack Trace actually from Symfony 6)The phpDoc of `Terminal::getSttyColumns` states> Runs and parses stty -a if it's available, _suppressing any error output_.The latter might refer to `['suppress_errors' => true]` (though I am not sure) - which is a Windows only functionality. In any case, since `Terminal::readFromProcess` already checks for```phpif (!$process = proc_open(…)) {    return null;}```and```phpif (!\is_resource($process)) {    return null;}```upstream in Symfony 6/7, indicating that `proc_open` might fail - this error can additionally be suppressed using `@`. Besides, `Process::start` also uses ``@proc_open`` (added insymfony/symfony@099481f "Prevent warning in proc_open()").Commits-------575249a3431 suppress proc_open errors
