Package: php-net-url2
Version: 2.2.1-0.2
Severity: important

Dear Maintainer,

First off, thank you for your work on the Debian version of the package!

The issue is, that after upgrading to Debian 13, a preg_replace_callback() error kicks in with the more strict regexp handling of PHP 8.4:

This regexp fails in /usr/share/php/Net/URL2.php in line 1201:

	([\x-\x20\x22\x3C\x3E\x7F-\xFF]+)

Produces a warning:

PHP Warning:  preg_replace_callback(): Compilation failed: digits missing after \x or in \x{} or \o{} or \N{U+} at offset 3 in /usr/share/php/Net/URL2.php on line 1200

But returns null for all string inputs, which breaks PHP applications, since with PHP8.2 it returned the input string untouched.
I bumped into this problem with Roundcube's calendar plugin working with a Radicale CalDAV server, which resulted missing remote calendars in the Roundcube webmail, after upgrading to Debian 13.
The correct regexp, which works as expected in PHP 8.4 too:

	([\x00-\x20\x22\x3C\x3E\x7F-\xFF]+)

The regexp changes of PHP 8.4 are documented here: https://php.watch/versions/8.4/pcre2-regexp-syntax-changes

The issue has already been corrected in version 2.2.3 of Net_URL2 on Pear.
Please update the Debian package to 2.2.3 or at least backport this particualar correction.

Until that, manually correcting this single line regexp in /usr/share/php/Net/URL2.php solves the problem.

In case you need any more information on this, I'd be glad to help!

Thank you in advance,
Andras Galos
