The URL defined "Text_Diff_Engine_native" is not working as expected.

Path : wp-includes/Text/Diff/Engine/native.php

I have attached a list of URLs that returned a 404 error.

​http://opensource.org/licenses/lgpl-license.php

I have found a list of URLs that returned a 404 error.

I have replaced 404 URL to a new valid URL.

@utsav72640 Thank you for the report

Due to the publication of a new licence version for the LGPL, I inspected those URLs and discovered that they all redirect to 404. I have added an attachment patch and updated it with a new URL.

Thanks

Hi there, thanks for the patch!

• Per the ​Text_Diff page on GitHub, it has been superseded by the ​Horde_Text_Diff package, which uses version 2.1 of the LGPL license, so ​https://opensource.org/license/lgpl-2-1/ would likely be the correct URL here as well, instead of the 3.0 version.
• The Algorithm::Diff URL should still link to version 1.06 for accuracy, so either of these URLs would be correct:
  • ​https://metacpan.org/release/NEDKONZ/Algorithm-Diff-1.06
  • ​https://cpan.metacpan.org/authors/id/N/NE/NEDKONZ/Algorithm-Diff-1.06.zip

In 55700:

External Libraries: Update license URL in Text_Diff library.

The former URL used to refer to LGPL 2.1 at the time, but does not redirect to its current location.

Includes updating the Algorithm::Diff Perl module URL.

Props jigar-bhanushali, utsav72640.
Fixes #58217.
