As a side note, the company I worked at used ASN.1 for five years to
encode all of its product's communication messages (Using PER
encoding), with what was supposed to be a highly optimized
implementation of ASN.1.
One of my last projects in the company was to try and convert our
encoding method (
Final update:
The problem was indeed with the message generation and serialization
in C#.
The class generator was called without the optional 'detectMissing'
flag, and so did not create nullable fields.
This seems to me as an unwanted default behaviour.

Does that sound like a realistic explanation?

Hi,
I'm seeing a strange behaviour of the protobuf library in the
following situation:
I have a message which contains an optional field uint32
'uploadLimit'.
I have created and serialized a message containing the value 0 in this
field.
When reading this message in Python and C#, I have the val
Scratch that.
I realized that using the has_field method I can check whether the
field was initialized, which is equivalent to None.

Hi,
I'm starting to use Protocol Buffers as a replacement for a
proprietary data serialization solution using Python, and was
wondering whether there is a way of providing a NULL (or a Python
'None') default value to a field.
Thanks,
