Continuously spawning php subprocess calls to OS eventually leading to memory exhaustion

[Kilill]

• OS: Win 10
• Php: 8 / 7 does not matter

Process growth can easly be seen in eiter Process Explorer or Task Manger

there seems to be 3 different commands at least 2 of wich repeat, all of them starts with:

C:\Windows\\system32\WindowsPowerShell\v1.0\powershell.exe -c "E:\php\php -r \"define('LARAVEL_START', microtime(true)); require_once 'w:\test/vendor/autoload.php'; $app = require_once 'w:\test/bootstrap/app.php'; class VscodeLaravelExtraIntellisenseProvider extends \Illuminate\Support\ServiceProvider { public function register() {} public function boot() { if (method_exists($this->app['log'], 'setHandlers')) { $this->app['log']->setHandlers([new \Monolog\Handler\NullHandler()]); } } } $app->register(new VscodeLaravelExtraIntellisenseProvider($app)); $kernel = $app->make(Illuminate\Contracts\Console\Kernel::class); $status = $kernel->handle($input = new Symfony\Component\Console\Input\ArgvInput,new Symfony\Component\Console\Output\ConsoleOutput); echo '___VSCODE_LARAVEL_EXTRA_INSTELLISENSE_OUTPUT___';*

then follows one of the following:

echo json_encode(array_map(function ($route) { return ['method' => implode('|', array_filter($route->methods(), function ($method) { return $method != 'HEAD'; })), 'uri' => $route->uri(), 'name' => $route->getName(), 'action' => str_replace('App\\Http\\Controllers\\', '', $route->getActionName()), 'parameters' => $route->parameterNames() ]; }, app('router')->getRoutes()->getRoutes()));echo '___VSCODE_LARAVEL_EXTRA_INSTELLISENSE_END_OUTPUT___';\""

or

$middlewares = array_merge(app('Illuminate\Contracts\Http\Kernel') ->getMiddlewareGroups(), app('Illuminate\Contracts\Http\Kernel') ->getRouteMiddleware()); foreach($middlewares as $key => &$value) { if (is_array($value)){ $value = null; }else{ $parameters = array_filter((new ReflectionMethod($value, 'handle')) ->getParameters(), function ($rc) { return $rc->getName() != 'request' && $rc->getName() != 'next'; }); $value=implode(',', array_map(function ($rh) { return $rh->getName().($rh->isVariadic()?'...':''); }, $parameters)); if(empty($value)){ $value=null; } }; } echo json_encode($middlewares);echo '___VSCODE_LARAVEL_EXTRA_INSTELLISENSE_END_OUTPUT___';\""

or

echo json_encode( array_merge( array_keys(Illuminate\Support\Facades\Gate::abilities()), array_values( array_filter( array_unique( Illuminate\Support\Arr::flatten( array_map( function ($val, $key) { return array_map( function ($rm) { return $rm->getName(); }, (new ReflectionClass($val))->getMethods() ); }, Illuminate\Support\Facades\Gate::policies(), array_keys(Illuminate\Support\Facades\Gate::policies()) ) )), function ($an) { return !in_array($an, ['allow', 'deny']); } ) ) ) ); echo '___VSCODE_LARAVEL_EXTRA_INSTELLISENSE_END_OUTPUT___';\""
