Reconsider the implementation of default values #114

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Currently nanopb dynamically initializes optional fields to default values.

This is a somewhat rarely used feature, and is not implemented for all field 
types (e.g. string pointers, extension fields).

Issue #79 could provide a smaller code size implementation for the same 
functionality, while allowing a faster memset() to zero to be used when default 
values are not needed. This however requires changes to user applications when 
default values are used.

Review this for nanopb-0.3.

This would cause default value initialization to not work with dynamically 
allocated values. Not sure if that is important or not.
