Algorithm?
Is the algo explicitly described somewhere? mentions Dairiki who says to have borrowed from Ned Konz, and GNU diffutils-2.7.

Some people like git diff, which according to uses  which is based on Myers. --Nemo 11:46, 14 September 2014 (UTC)

"wikidiff2: command not found" errors
On an Ubuntu 14.10 server after manually updating from MW 1.19 to 1.23.8, all diff pages reported "No difference," even when a difference was clearly apparent. Diffs worked as expected under 1.19. Apache's logs threw `/bin/bash: wikidiff2: command not found` when loading the diff page. This error appears to be unrelated to the wikidiff2 extension, and setting $wgExternalDiffEngine in LocalSettings.php (which was not previously set) to wikidiff3 had no effect; instead, removing an installed Ubuntu package named `php-wikidiff2` from the server resolved the problem, and diffs worked as expected. A google search unearthed a wmflabs IRC log from 2013, which was the only resource I found when searching for this error message. Users spectie and marktraceur reported the resolution. --75.175.21.212 19:21, 21 December 2014 (UTC)

"php-wikidiff2" vs "wikidiff2" in php.ini
Just pointing out that in my Ubuntu default installation wikidiff2 is installed with the name wikidiff2.so, not php-wikidiff2. This means that "extension = php_wikidiff2.so" should be "extension = wikidiff2.so" The error that indicates the problem is: sh: 1: wikidiff2: not found and on apache restart: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20121212/php_wikidiff2.so' - /usr/lib/php5/20121212/php_wikidiff2.so: cannot open shared object file: No such file or directory in Unknown on line 0
