" Right now the last release is totally unusable"
Am I missing something? We're using Opcache (Zend) on Windows in PHP 5.5.2,
with good results. What issues are people seeing?

opcode caching performance, due to their proximity to the Zend core developers
(<grin>). Further, we're trusting them to provide a highly performant opcode
cache on Windows (using cross-processes shared memory, appropriate Win32 APIs,
etc.).

For various reasons, some fixable and other will be hardly fixable without
changes in the engine
It would be nice if it is possible to have an alternative at least for a year
or two. Also windows as a whole is not a priority for Zend, for quite some
time. So ideally we should take care of this to ensure outstanding or at least
sync performance and stability.

I know there are some issues:
https://github.com/zendtech/ZendOptimizerPlus/issues?state=open
And OPcache for Windows is not behaving properly, because it uses fixed
memory addresses for the cache (although the X64 version is not using
the hard-coded address).
I would not be surprised if a report like this is caused by the bad
memory allocation of OPcache:
http://www.apachelounge.com/viewtopic.php?p=25439#25439
But I would not call it "totally unusable". It is running fine on my
Win2k8 production server (still PHP 5.3) and on my Win2k8 development
server (PHP 5.3 as mod_php alongside PHP 5.5 x64 mod_fcgid).
I am running Apache 2.4.6, Keith is running IIS. What makes you say it
is unusable?

Uh, this is news to me. We did our full release testing with WinCache + Zend
Opcache enabled (NTS x86) and no failures were reported. If there are things
we should be telling our customers, now is the time to let us know...

We are marking the opcode cache portion of WinCache as "deprecated" in 1.3.5;
This is the first step towards removal of the code. We would like to get the
(WinCache + Zend Opcache) configuration "baked" for one full PHP release cycle.
So the soonest we would consider removing the WinCache opcode cache would be
at the PHP 5.6 release time.

Hm. Going off the number of installs of PHP via the Web Platform Installer
(WPI), I would *hope* that Zend would consider Windows customers in their
plans. ^_^

I just filed this bug report, but given this is appears to be such a Windows
specific issue, I figured I'd post it here as well and see what feedback I got:
https://github.com/zendtech/ZendOptimizerPlus/issues/127
Unable to create view for file mapping
No milestone
No one is assigned
There was a problem with your request, please try again
The content you are editing has changed. Reload the page and try again.
On my primary development machine (Windows 7 x64, IIS 7, PHP 5.5.2), I am
experiencing this about every couple of days. I get an FastCGI has exited
unexpectedly error and in the Event Viewer, I have this:
________________________________________
Log Name: Application
Source: Zend OPcache
Date: 8/27/2013 3:33:37 PM
Event ID: 8
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: KDAVIS.pridedallas.com
Description:
The description for Event ID 8 from source Zend OPcache cannot be found. Either
the component that raises this event is not installed on your local computer or
the installation is corrupted. You can install or repair the component on the
local computer.
If the event originated on another computer, the display information had to be
saved with the event.
The following information was included with the event:
Unable to create view for file mapping
Not enough storage is available to process this command.
________________________________________
I have fixed this 2 different ways. The first is to run opcache_reset() from
localhost (a page that is blank except for this command will load for some
reason.)
Today, I fixed this by changing the IRPStackSize value in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters to
20 (per http://support.microsoft.com/kb/106167.)
Still, this seems like a bug to me.
