I've made an attempt to create a Python3 compatible version of protobufs. I have some code that passes pretty much all the unit tests which I've posted here:
https://github.com/openx/python3-protobuf I probably won't have a chance to look at this again for a couple weeks if not longer, so I want to get it out there. In my attempt I decided to follow the advice in another post, and treat python3 as a new language. To get python3 working, you'll have to compile the C code. There are also a few issues I ran into along the way: - I decided to use strings where unicode is used in Python 2. I was originally going to try to use bytes/bytearrays, but they do not support >8 bit characters, and some of the setup.py tests use "exotic" 16 bit chrs. (Warning: I might have something conceptually wrong here) - There are places where byte data is stored as strings, then converted to unicode. I ended up converting strings (I called them bytestr's) to normal strings. I'm not sure this is done correctly everywhere though. - Data is packed/unpacked using struct.pack/unpack which is done using bytes instead of strings in Python3. I have simple string_to_bytes() and bytes_to_string() functions to do this. What's left is: - There are a couple Exceptions that I don't throw. They are supposed to be where the Python2 code converts from unicode strings to regular strings. I am definitely missing something conceptually here - I haven't figured out how Python 2x supports strings with "exotic" characters, but not strings like u'a\x80a'. If someone can solve this problem & figure out when to throw the exceptions Python3 will be *fully* working. I might have small bits of time here or there but I don't think I can devote the time I need to get this finished for several weeks, so if someone wants to finish this up, feel free to fork this code. If anyone wants to see what I did, the best way to do this is to diff between the latest commit and commit 49ccf5d8b3b688c335dc35bcb9f219eca78c7210. Thanks!
