Domain 'localhost' is stripped from input URL about purl HOT 9 CLOSED

More generally, the same output occurs when replacing "localhost" with any single-label domain, e.g. "foo".

from purl.

The assumption that the URL is going to be multi-label seems to be hard-coded into Purl's API, e.g. $url->publicSuffix, $url->registerableDomain.

An example of correct behavior would be PHP's parse_url:

echo parse_url("http://foo/", PHP_URL_HOST) . "\n";

which outputs

foo

from purl.

Note that this bug is also present in https://github.com/auraphp/Aura.Uri which also uses the public suffix list.

The issue with Aura.Uri is here.

The issue seems to be hard-coded in the source, too: https://github.com/jwage/purl/blob/master/src/Purl/Parser.php#L40

from purl.

The issue is not present in version 0.0.2.

from purl.

This is odder than I thought. The behavior of 0.0.2 is different when executed using the command line to when executed on a web server. Specifically, "localhost" gets elided when using the web server but not when using the command line.

@jameshfisher Thanks for the bug report. I'll take a look at it later today and let you know what I come up with.
