Zend Data Cache: APC compatibility broken

[weierophinney]

The Zend Data Cache comes with a compatibility layer for APC but the APC adapter doesn't work with it:

curl -sS -v 'http://localhost/test-zend-cache.php'
* About to connect() to localhost port 80 (#0)
*   Trying ::1...
* Connected to localhost (::1) port 80 (#0)
> GET /test-zend-cache.php HTTP/1.1
> User-Agent: curl/7.29.0

> Accept: */*

< HTTP/1.1 200 OK

< 
.............E.......E..EE..E.E.E.....E......E.FF.F.FF......SEEE. 65 / 72 ( 90%)

I currently don't get the full result. Could be a segmentation fault somewhere but it's a bit more work as the Zend Data Cache doesn't run in CLI and this bug is not very impotent.

-> For now if you are using the Zend Data Cache than please use one of the ZendServer[Disk|Shm] adapters.

It should be a bug in apcu or acp_bc. Minimum required versions for each PHP versions are corrected in tests included in #153

@thomasvargiu this issue is not about apcu_bc, this is about the apc compatibly layer of the zend data cache (part of zend server)

@marc-mabe Ok, I don't know Zend Data Cache, but I think it could be a problem of Zend Data Cache. What do you think? And it's a 2 years old issue.

@thomasvargiu Needs to be checked with the current Zend Server version if the problem still persist.
If so it should either be fixed (FZ or Zend Server) or at least be documented -> to use the specialized ZendServer[Disk|Shm] adapters.

I will close this as with the next minor version, we will bump PHP minimum version to 7.3.
There is no working APC extension for PHP 7.0+ and thus the APC component will not be part of this project.

@Ocramius Just to make sure that I'm on the right track:

• TSC decided to bump PHP versions in minors
• PHP version 7.0+ does not have a working APC extension
• next minor thus can drop the APC class as it wont work either on PHP 7.0+
• next minor will have several satellites as per TSC voting

Thats a BC break, isnt it? But it might be a problem we probably cannot solve?
