Regression: cURL module enabled and requiring Sockets API on "May 1 2017 18:43:30" PHP build

[Geoffrey Arnold]

Hello,

As of today at 3PM CT one of our PHP apps running in Standard Environment is failing with the following error when attempting to issue a HTTP request through Guzzle:

The Socket API will be enabled for this application once billing has been enabled in the admin console.

...

Slim Application Error:

Type: GuzzleHttp\Exception\ConnectException

Message: cURL error 6: Couldn't resolve host 'XXX' (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

File: /base/data/home/apps/s~XXX/20170411t051226.400475517246811550/vendor/guzzlehttp/guzzle/src/Handler/CurlFactory.php

Line: 186

This application does do not have cURL or GAE's cURL "lite" enabled, so it appears that the "May 1 2017 18:43:30" GAE PHP build is causing the cURL module to be loaded and require the Sockets API.

Any help would be greatly appreciated,

Geoff.
