Using `"stream" => true` in options makes PSR7 responses read-once about guzzle

[GrahamCampbell]

If you're using ext-curl, this happens here:

guzzle/src/Handler/CurlFactory.php

Line 401 in d95d9ab

$options['sink'] = \GuzzleHttp\Psr7\Utils::tryFopen('php://temp', 'w+');

. The threshold where by we move from in-memory to on disk depends on PHP config, the default being 2MB according to https://www.php.net/manual/en/wrappers.php.php.

[GrahamCampbell]

You should disable the stream option. It doesn't solve the problem you are asking about. We already buffer things to disk when it exceeds some threshold which I don't remember (something like 1MB).

Thank you; out of interest, can you point me towards the code which buffers to disk so I can understand how this works?
