Summary: BUCK always defines NDEBUG on Android builds. This is a longstanding issue and it's tricky to work around. Previous attempts to fix this within React Native were difficult because disabling NDEBUG caused lots of issues that were difficult to track down. Instead, I am (1) introducing a new RN_DEBUG flag that can be used cross-platform, (2) whenever NDEBUG is *not* enabled, RN_DEBUG will automatically be defined, (3) enables debug-only code to be compiled on Android, (4) enables us to selectively, slowly migrate `assert` to `rn_assert` in a way that doesn't impact non-Android platforms, but allows us to maintain stability of Android debug builds. Actually enabling the RN_DEBUG flag in debug builds is done in FB-internal code. I assume the NDEBUG issue is not a problem when compiling in open-source without BUCK.

// Enable RN_DEBUG if NDEBUG is not defined.

// Due to BUCK defaults in open-source, NDEBUG is always defined for all android
|
|
// builds (if you build without BUCK, this isn't an issue). Thus we introduce
|
|
// RN_DEBUG that we use internally instead of NDEBUG that we can control and use
|
|
// as a more reliable xplat flag. For any build that doesn't have NDEBUG
|
|
// defined, we enable RN_DEBUG for convenience.
