Summary: Enabling both php_opcache and php_wincache AVs on
shutdown

Wincache.ocenabled is PHP_INI_ALL, meaning that the Wincache opcode cache can
be enabled/disabled by script or by user.ini. This is the same for Zend
Opcache opcache.enabled and APC apc.enabled. To support this, the interned
strings have to be hooked at module load time. This is how all three opcode
caches implement the hooking of interned strings.

@Anatol: which older versions? PHP 5.4.x users that run into this problem
should upgrade to 5.4.18, the moment that is released with this patch. Making
special arrangements for older 5.4.x users would be a waste of developer
resources IMO.
And PHP 5.3 (or lower) users do not run into this, because interned_string was
introduced in the Zend engine for 5.4.

Jan, I meant exactly that, there still will be some users on versions lower
than
5.4.17 or which is the current. The question is just whether it's worth the
effort
to be aware of that.

@Anatol: there is no need to disable interned strings in extensions for older
PHP-versions if you backport the patch. I do not think I have the karma to put
a patch here, but this is the backport for PHP 5.4:
http://x32.elijst.nl/zend_interned_strings_shutdown_AV.patch
Maybe except for some line numbers it is literally the same patch.

@Eric ok, so the catch is to use the wincache with disabled opcode cache.
Whereby
interned strings are neither opcode cache nor any other functionality. The
patch
would solve it only for newer PHP versions, maybe it should be possible to
disable
interned strings explicitly in wincache/opcache, maybe per ini? That would
solve
it also for users with older PHP without TS.
@Jan that's obvious now where people start to mix the cache engines :)

Agreed,should be applied in php-src and
github repos.
