Driving home, I realized how vague this was.
Specifically, I'm looking for information on when APC will cache a file
or directory, and what it checks before doing so.
Thanks again,
Aaron Holmes

Hello,
I'm trying to find some information on APC opcode cache behavior.
We noticed an issue where, when switching symlinks to different
versions of sites, old code was running from the previous version
after switching the symlink.
Anyone know where I can find more information on this?
Thanks,
Aaron holmes

Yes, that is the case. And iirc it will not update the cache if the mtime of the
new "switched" file is not newer. If you switch you must either restart the
apache or touch the files.

You can also write a little script that clears the APC cache, something in the
line of:
#!/usr/bin/php
<?php
apc_clear_cache();
And execute this script each time you deploy. (can also be a command such as
php -r "apc_clear_cache();"). This way you'll avoid restarting the webserver
and it will clear all APC cache forcing APC to cache everything again.
Greetings.
