Uploads break after 30 seconds

[thekid]

Coming from thekid/dialog#8 (comment), while uploading via curl works, it doesn't when using this library.

Test script

use io\File;
use lang\Throwable;
use util\cmd\Console;
use webservices\rest\{Endpoint, RestUpload};

$api= new Endpoint($argv[2]);
$transfer= new File($argv[1]);
$target= 'target.mp4';

// Test code
Console::writeLine('Upload ', $transfer, ' ', $transfer->size());
$upload= new RestUpload($api, $api
  ->resource('images/{0}', [$target])
  ->request('PUT')
  ->waiting(read: 3600)
);
try {
  foreach (['video' => $transfer] as $kind => $file) {
    $upload->transfer($kind, $file->in(), $target);
  }
  $r= $upload->finish();
  Console::writeLine('-> ', $r);
} catch (Throwable $t) {
  $t->printStackTrace();
}

We also have debug output in webservices.rest.RestUpload::transfer() to show progress!

👉 after 30 seconds, things begin failing, fputs() doesn't return false but raises all these 1259 SSL: Eine bestehende Verbindung wurde softwaregesteuert durch den Hostcomputer abgebrochen warnings.

Cannot reproduce this with dialog running on localhost, even if I slow down the uploads so that they take significantly longer than 30 seconds:

BEGIN target.mp4 [
  <22:01:32>.................
  <22:01:33>..............................
  # ...
  <22:02:25>...............................
]
-> webservices.rest.RestResponse(200 OK)@{
  Date: Mon, 26 Sep 2022 20:01:32 GMT
  Server: XP
  Connection: close
  Content-Type: application/json
  Content-Length: 0
}

If I slow down upload artifically, the timeout doesn't occur after 30 seconds, but later:

BEGIN target.mp4 [
  <22:12:19>..................
  <22:12:20>.............
  # ...
  <22:13:47>............
