hi, im trying to do synchronous command pool, but i give Catchable Fatal Error: Argument 1 passed to Aws\Handler\GuzzleV5\GuzzleHandler::Aws\Handler\GuzzleV5{closure}() must be an instance of Exception, string given, called in ......../vendor/guzzlehttp/promises/src/Promise.php on line 199 and defined
any idea ? :)
i using guzzle 5.3 which is supported, when im looking at packagist
It returns a promise, so you can call
->wait() on that if you need to block until the upload is complete
that's what I thought as well, however when I was issuing the
->uploadAsync() method, nothing was getting uploaded. I had a separate timer instead of calling wait, but checked on the value returned by the promise ->then() method, and also checking S3 directly, the file never uploaded
in fact most of them
So it looks like all uploads will start
But multipart uploads may not finish before the end of a script
this is the test I was running:
$s3 = new \Aws\S3\S3Client([
'region' => 'us-west-2',
'version' => 'latest',
'debug' => true,
]);
$uploads = [
'small' => $s3->uploadAsync(
'testing-testing-testing',
'small-file-async-upload',
fopen(__FILE__, 'r')
),
'large' => $s3->uploadAsync(
'testing-testing-testing',
'large-file-async-upload',
fopen(__DIR__ . '/phparchitect-2015-06.pdf' , 'r'),
'private',
[
'before_upload' => function (\Aws\CommandInterface $command) {
echo "uploading chunk {$command['PartNumber']}\n";
}
]
)
];
echo "uploading\n";
\GuzzleHttp\Promise\queue()->run();
The second upload is large enough to trigger a multipart upload
Which is handled by a Guzzle coroutine
And coroutines might not be complete before the call to
\GuzzleHttp\Promise\queue()->run() finishes
creating a test script now
but does that fit the general characteristics of the issue you’re facing?
the script terminates and uploads still haven’t finished
it just keeps waiting for it but never completes, and chekcking separately on S3, nothing ever gets uploaded
Guzzle doesn’t have a built in event loop, so coroutines and functions registered with
->then need some prompting
This can either be by calling
->wait, which will unwind a full promise stack
but the upload will kick off additional promises
where the React loop will tick the Guzzle loop
and that can achieve something close to what you’re describing
He wrote a blog post about it here: http://blog.wyrihaximus.net/2015/06/aws-php-sdk-asynchronously/
so I'm working with this basic example
```php
```php
<?php
$uploading = 0;
$AWS = new Aws\Sdk([
'version' => 'latest',
'region' => 'us-east-1',
'credentials' => [
'key' => '***',
'secret' => '***',
]
]);
$S3 = $AWS->createS3();
echo "beginning first promise\n";
$uploading ++;
$promise1 = $S3->uploadAsync('tantor-books', 'Test/test.xml', fopen('/mnt/olympus/Books/0087_CoalHuman/Download/0087_CoalHuman.xml', 'r'));
$promise1->then(function() use ($uploading) {
$uploading --;
});
echo "beginning second promise\n";
$uploading ++;
$promise2 = $S3->uploadAsync('tantor-books', 'Test/test.zip', fopen('/mnt/olympus/Books/0087_CoalHuman/Download/0087_CoalHuman.zip', 'r'));
$promise2->then(function() use ($uploading) {
$uploading --;
});
echo "beginning loop\n";
while ($uploading != 0) {
echo 'uploading: '.$uploading."\n";
}
and just running that, the script will never exit, as it will loop continuously on the last section, as the
$uploading value never changes, because the then() functions aren't firing, because the files never upload. I've also let it run and checked externally to see if the files ever showed up on the S3 bucket, and they didn't, which leads me to believe that the uploadAsync() method isn't firing when called
