Debug Builds & Custom Logging
=============================
When building GCDWebServer in "Debug" mode versus "Release" mode, GCDWebServer logs a lot more information and also performs a number of internal consistency checks. To disable this behavior, make sure to define the preprocessor constant ```NDEBUG``` when compiling GCDWebServer. In Xcode target settings, this can be done by adding ```NDEBUG``` to the build setting ```GCC_PREPROCESSOR_DEFINITIONS``` when building in Release configuration (this is done automatically for you if you use CocoaPods).
When building GCDWebServer in "Debug" mode versus "Release" mode, GCDWebServer logs a lot more information and also performs a number of internal consistency checks. To enable this behavior, define the preprocessor constant ```DEBUG=1``` when compiling GCDWebServer. In Xcode target settings, this can be done by adding ```DEBUG=1``` to the build setting ```GCC_PREPROCESSOR_DEFINITIONS``` when building in Debug configuration.
It's also possible to replace the logging system used by GCDWebServer by a custom one. Simply define the preprocessor constant ```__GCDWEBSERVER_LOGGING_HEADER__``` to the name of a header file (e.g. "MyLogging.h") that defines these macros:
```
#define LOG_DEBUG(...) // Should not do anything if NDEBUG is defined
#define LOG_DEBUG(...) // Should not do anything unless the preprocessor constant DEBUG is non-zero
#define LOG_VERBOSE(...)
#define LOG_INFO(...)
#define LOG_WARNING(...)
#define LOG_ERROR(...)
#define LOG_EXCEPTION(__EXCEPTION__)
#define DCHECK(__CONDITION__) // Should not do anything if NDEBUG is defined or abort if __CONDITION__ is false
#define DNOT_REACHED() // Should not do anything if NDEBUG is defined
#define DCHECK(__CONDITION__) // Should not do anything unless the preprocessor constant DEBUG is non-zero
#define DNOT_REACHED() // Should not do anything unless the preprocessor constant DEBUG is non-zero
```
