5.3.13

Description

I have default_socket_timeout set to -1 (which is supposed to mean some big timeout). I noticed a bug, which appears when I'm trying to stream response: I have "Idle timeout reached" error.

How to reproduce

$response = $httpClient->request('GET', 'https://example.org');
$stream = $response->toStream();

which gets us the next call chain

• symfony/src/Symfony/Component/HttpClient/Response/CommonResponseTrait.php

  Line 112 in 4b41d17

  public function toStream(bool $throw = true)

• symfony/src/Symfony/Component/HttpClient/Response/CommonResponseTrait.php

  Line 116 in 4b41d17

  $this->getHeaders($throw);

• symfony/src/Symfony/Component/HttpClient/Response/TransportResponseTrait.php

  Line 64 in 4b41d17

  public function getHeaders(bool $throw = true): array

• symfony/src/Symfony/Component/HttpClient/Response/TransportResponseTrait.php

  Line 67 in 4b41d17

  self::initialize($this);

• symfony/src/Symfony/Component/HttpClient/Response/CommonResponseTrait.php

  Line 141 in 4b41d17

  private static function initialize(self $response): void

• symfony/src/Symfony/Component/HttpClient/Response/CommonResponseTrait.php

  Line 149 in 4b41d17

  foreach (self::stream([$response], -0.0) as $chunk) {

• symfony/src/Symfony/Component/HttpClient/Response/TransportResponseTrait.php

  Line 151 in 4b41d17

  public static function stream(iterable $responses, float $timeout = null): \Generator

• symfony/src/Symfony/Component/HttpClient/Response/TransportResponseTrait.php

  Line 193 in 4b41d17

  $multi->handlesActivity[$j] = [new ErrorChunk($response->offset, sprintf('Idle timeout reached for "%s".', $response->getInfo('url')))];

where at the last point $timeoutMax equals 0, so any elapsed time will exceed this value.

Possible Solution

$timeoutMax value should be set to some big number instead of zero.
