While installing PHP APC, I received two unexpected questions. I had previously installed APC at a test environment and did not receive these questions.
The questions are:
- Enable per request file info about files used from the APC cache
- Enable spin locks (EXPERIMENTAL)
Here are the initial few lines of installation:
# pear install pecl/apc WARNING: channel "pecl.php.net" has updated its protocols, use "channel-update pecl.php.net" to update downloading APC-3.1.6.tgz ... Starting to download APC-3.1.6.tgz (148,835 bytes) ..........................done: 148,835 bytes 49 source files, building running: phpize Configuring for: PHP Api Version: 20041225 Zend Module Api No: 20060613 Zend Extension Api No: 220060519 1.

Does anyone know what these questions do? What would the proper answers be?
