Avoid Guzzle 6.5.0

[bramus]

Description

A client of mine reported that he could no longer upload photos to an S3 bucket. The upload failed with the following message:

Use of undefined constant INTL_IDNA_VARIANT_UTS46 - assumed 'INTL_IDNA_VARIANT_UTS46'

I tracked the issue down to Guzzle 6.5.0 which was just released. They use the constant without checking for its existence. There's an issue on their project for this: guzzle/guzzle#2448

Awaiting a new release from them, I'd recommend Craft to downgrade the included Guzzle to 6.4.1.

Users of Craft can – for now – downgrade manually by invoking:

composer require guzzlehttp/guzzle:6.4.1

To give you an idea of the scope of this issue: all CentOS 6 servers for example are affected by this.

Steps to reproduce

1. Upgrade to latest Craft
2. Run it on a Centos 6 server for example (or any server with an outdated libicu library)

Additional info

• Craft version: 3.3.18 (or maybe even earlier)
• PHP version: any
• Plugins & versions: libicu 4.2.1

More specifically - I get this error any time I attempt to install a plugin or update craft. I'm using an Apache server.

When I try to downgrade guzzle - I get this error:

Problem 1
- The requested package craftcms/cms (locked at 3.3.17, required as 3.3.18.1) is satisfiable by craftcms/cms[3.3.17] but these conflict with your requirements or minimum-stability.

Looks like this only affects servers with ICU < 4.6, which is pretty old, and a fix is being worked on, so expecting this will resolve itself in the next day or so, and probably not worth a Craft release.

In the meantime if you are getting bit by this, you can force Guzzle < 6.5.0 by adding this to your composer.json:

"require": {
  "guzzlehttp/guzzle": "~6.4.0",
  "...": "..."
}

Then run composer update.

Will keep this open for now and reassess in a couple days.

Thanks Brandon - That did the trick

Not thrilled with Guzzle’s reaction time on this, so just released Craft 3.3.18.2 which explicitly excludes Guzzle 6.5.0. The fix is slated for Guzzle 6.5.1, so I’m allowing 6.5.1+ for whenever that does get released.

Thanks for the intervention @brandonkelly!
