Installer claims: "Warning: Could not find APC, XCache or WinCache. Object caching is not enabled." However, this is php 5.5 and the web suggests that APC-like functionality is apparently pre-integrated. I would suggest making the installer not mention things that are not relevant ... like wincache on Unix, or any of this muck on php equal to or beyond 5.5.
Which MediaWiki version is this about? 1.22.0?
Yes 1.22.0
BTW apparently it's php > 5.4 not php > 5.5 where APC is built in.
- The Zend OPcache extension is shipped and by default enabled with PHP 5.5. Cf. http://www.php.net/manual/en/migration55.new-features.php - Zend OPcache doesn't contain an object-level cache. MediaWiki can takes advantage of a cache allowing to store object representations (calling for APC the apc_store function). - Nor PHP 5.4, nor PHP 5.5 include APC. But PHP 5.4 introduced a new extension API. Recent versions for APC works at a stable quality on PHP 5.3, but not on PHP 5.4 or PHP 5.5. APC development hasn't been active since 2012. - In October 2013, an XCache version with PHP 5.5 support has been released.
In confirm the bug, in the extent we should detect the PHP version and stop to recommend to install APC in 5.4+, as it could only lead system administrators to try to install a broken stable or unstable beta extension on newest PHP versions.
