UvDriver cannot scan empty dir

[Robert Lu]

For this code:

<?php
require __DIR__ . '/vendor/autoload.php';

use Amp\File;
use Amp\Loop;
use App\App;

Loop::run(function () {
    $flist = yield File\scandir("/tmp/tmp/");
    var_dump($flist);
});

/tmp/tmp is empty dir

---

Run php72 -dmemory_limit=1024m /path/to/php.php, it throw a excepiton:

PHP Fatal error:  Uncaught Amp\File\FilesystemException: Failed reading contents from /tmp/tmp/ in /opt/pkgist/vendor/amphp/file/lib/UvDriver.php:420
Stack trace:

But run env AMP_LOOP_DRIVER='\Amp\Loop\EvDriver' php72 -dmemory_limit=1024m /path/to/php.php, it works normally:

array(0) {
}

Which version of libuv do you have? I've found this in the changelog.

[Robert Lu]

php72-php-fpm-7.2.1-1.el7.remi.x86_64
php72-php-pecl-uv-0.2.2-2.el7.remi.x86_64
libuv-1.10.2-1.el7.x86_64

I think @bwoebi needs to update php-uv to support libuv 1.0. In the mean time I committed a work-around in 04f047a.

Thanks @trowski, fixed it upstream: amphp/ext-uv@72aa710
