PHP 8.6 IO Copy API breaks STREAM_NOTIFY_PROGRESS and STREAM_NOTIFY_COMPLETED

[TimWolla]

Description

The following code:

<?php

function stream_notification_callback($notification_code, $severity, $message, $message_code, $bytes_transferred, $bytes_max) {
    switch($notification_code) {
        case STREAM_NOTIFY_RESOLVE:
        case STREAM_NOTIFY_AUTH_REQUIRED:
        case STREAM_NOTIFY_FAILURE:
        case STREAM_NOTIFY_AUTH_RESULT:
            var_dump($notification_code, $severity, $message, $message_code, $bytes_transferred, $bytes_max);
            /* Ignore */
            break;

        case STREAM_NOTIFY_COMPLETED:
            echo "Transfer completed with ", $bytes_transferred, " bytes";
            break;

        case STREAM_NOTIFY_REDIRECTED:
            echo "Being redirected to: ", $message;
            break;

        case STREAM_NOTIFY_CONNECT:
            echo "Connected...";
            break;

        case STREAM_NOTIFY_FILE_SIZE_IS:
            echo "Got the filesize: ", $bytes_max;
            break;

        case STREAM_NOTIFY_MIME_TYPE_IS:
            echo "Found the mime-type: ", $message;
            break;

        case STREAM_NOTIFY_PROGRESS:
            echo "Made some progress, downloaded ", $bytes_transferred, " so far";
            break;
    }
    echo "\n";
}

$ctx = stream_context_create();
stream_context_set_params($ctx, array("notification" => "stream_notification_callback"));
$f = fopen('compress.zlib://http://localhost:8080/index.php.gz', 'r', false, $ctx);
var_dump(trim(stream_get_contents($f)));

running against PHP’s development web server where index.php.gz is equal to the decoded H4sICPQfX2oAA2luZGV4LnBocADzSM3JyVcIzy/KSVHkAgDd3RR9DQAAAA==

Resulted in this output:

Connected...
Found the mime-type: application/gzip
Got the filesize: 43
Made some progress, downloaded 0 so far
string(12) "Hello World!"

But I expected this output instead:

Connected...
Found the mime-type: application/gzip
Got the filesize: 43
Made some progress, downloaded 0 so far
Made some progress, downloaded 43 so far
Transfer completed with 43 bytes
string(12) "Hello World!"
