I got a prompt with Enable internal debugging in APC [no]:. While installing APC.
- what is APC internal debugging?
- Is is better to keep it enabled?
Tried to do a search but couldn’t find an answer!
This message comes from the pear package of APC. If you set it, APC will be configured with the
--enable-apc-debugflag, which means the macro__DEBUG_APC__is set in the C source code.This macro will add additional printfs about APC’s internal state. Naturally, these are only useful in a testing environment, and should never be activated on a public webserver.
Unless you’re editing APC’s source code, or tracking down an extremely low-level problem in APC (which is unlikely), you should answer no. You can just hit Enter.
