[php-src] Issue #8641: [Stream] STREAM_NOTIFY_COMPLETED over HTTP never emitted

Issue: https://github.com/php/php-src/issues/8641 Author: sfaut ### Description The following code: ```php <?php function progress($notification_code, $severity, $message, $message_code, $bytes_transferred, $bytes_maximum) { printf( "%d\t%s\t%d\t%d\r\n", $notification_code, $notification_code == STREAM_NOTIFY_COMPLETED ? 'T' : 'F', $bytes_transferred, $bytes_maximum, ); }; $context = stream_context_create(); stream_context_set_params($context, ['notification' => 'progress']); $stream_source = fopen('https://datasets.imdbws.com/title.ratings.tsv.gz', 'r', false, $context); // 6 MB file $stream_destination = fopen('title.ratings.tsv.gz', 'w'); stream_copy_to_stream($stream_source, $stream_destination); ``` Resulted in this output: ``` 2 F 0 0 4 F 0 0 5 F 0 6223383 7 F 0 6223383 7 F 8192 6223383 7 F 16384 6223383 7 F 24576 6223383 ... 7 F 6207960 6223383 7 F 6216152 6223383 7 F 6223383 6223383 ``` But I expected this output instead: ``` 2 F 0 0 4 F 0 0 5 F 0 6223383 7 F 0 6223383 7 F 8192 6223383 7 F 16384 6223383 7 F 24576 6223383 ... 7 F 6207960 6223383 7 F 6216152 6223383 8 T 6223383 6223383 ``` With the last $notification_code = 8 as "STREAM_NOTIFY_COMPLETED". Note that the last row has not always $bytes_transferred == $bytes_maximum Thx :) ### PHP Version PHP 8.1.6 ### Operating System Windows 10
