Endless loop when hostname is "dev"

See original GitHub issue

Current behavior

When baseUrl is set to http://dev:3000, cypress run hangs. Enabling DEBUG env var shows Cypress stuck in a loop, due to incorrect parsing of hostname from URL.

In this case, dev is incorrectly parsed as the tld, instead of the domain, since there is now “.” separator.

(See Debug Logs below)

Desired behavior

When baseUrl is set to http://dev:3000, dev would be detected as the domain, not a tld and cypress run would continue to completion.

Test code to reproduce

CYPRESS_baseUrl=http://dev:3000 cypress run

Cypress Version

11.0.1

Node version

v16.16.0

Operating System

Debian GNU/Linux 11 (bullseye)

Debug Logs

I can't include them all because it loops without end, but here was the important line:


cypress:network:cors Parsed URL { port: '3000', protocol: 'http:', subdomain: null, domain: '', tld: 'dev' } +2ms

We have had a variety of issues with docker domain names / host entries that don’t have a “.” in them - Firefox also has issues parsing them out. I’m having trouble searching for the other ones, but we’ve had similar problems in the past.

The workaround is usually not too bad, as @originalhat pointed out - use a “.” somewhere in the baseUrl. Switching to an IP works; “dev.dev” probably would as well.

If someone wants to dig into this particular case more and make a PR, we’d definitely look at it.

@mjhenkes the problem is the host name is being parsed by the Public Suffix domain validator, but it has no “.” notation so it should never make it to domain validation (it’s just a local host name)

this regression was introduced sometime around 10.10+ (10.9 worked fine)
