Application stucks when launch application that requires elevated privileges on Windows #51
Description
The following code:
Loop::run(static function () {
$process = new Process("diskpart");
yield $process->start();
});
Problem: app just stucks and does not stdout anything, using a timeout completely breaks the script execution:
Loop::run(static function () {
$process = new Process("diskpart");
yield timeout($process->start(), 5000);
});
Here an exception:
PHP Fatal error: Uncaught Exception: stream_select(): supplied resource is not a valid stream resource in C:\Users\Admin\Documents\win_install_stuff\windows_installer_v0\vendor\amphp\amp\lib\Loop\NativeDriver.php:79

I found a possible solution to solve this problem, but I'm not good at creating PR.
By adding the following code to "lib/Internal/Windows/SocketConnector.php" at the end of the function "onProcessConnectTimeout" (I added after the line 367)
if ($handle->status === ProcessStatus::STARTING) {
Loop::cancel($handle->childPidWatcher);
$handle->pidDeferred->fail($error);
}
The problem is solved completely and now the output when running the first script:
PHP Fatal error: Uncaught Amp\Process\ProcessException: Failed to create child process: 740: Запрошенная операция требует повышения. in C:\Users\Admin\Documents\win_install_stuff\windows_installer_v0\vendor\amphp\process\lib\Internal\Windows\SocketConnector.php:359
