*.proto API files?

[Shawn Lewis]

Can't find 'em in the API source.

In this old thread someone mentioned they'd be released soon, but that was 2008. I'm probably just not looking hard enough.

Thanks!

Hi Shawn,
I'm not sure exactly what you're looking for, but this has been open
source for quite some time. In the case of Python see:
http://code.google.com/p/googleappengine/source/browse/#svn%2Ftrunk%2Fpython%2Fgoogle%2Fnet

And for a very tedious usage example:
http://code.google.com/p/googleappengine/source/browse/trunk/python/google/appengine/datastore/datastore_pb.py

As I recall, the App Engine implementation differs from the open
source implementation. I'm not sure of the specifics of that and have
never personally verified that -- its just something I recall from
some threads long ago.

Are you looking for the .proto definition files used to generate the Python code? As far as I know, we haven't open sourced those files. I think that up till now, it hasn't been necessary, and no-one (that I can tell) has requested them for a few years.

Is there a particular reason why you'd like to see these, or is it out of curiosity?

It's an implementation detail, but yeah, the Python 2.5 runtime uses the old proto1, whereas Python 2.7 uses proto2.

I should be able to get the information I was after from the compiled
python protocol buffers.

But to answer your question, in this case I was wondering what the
behavior is when .setCount isn't called on the NextResult pb in
QueryResultsSourceImpl.java. Of course I could glean the default value
by running code that calls it, but I prefer looking at code. Also,
perhaps the default is set on the other side of the RPC, in which case
I'll never have access.

Not having the proto files feels like a dead end in the java source.
I'm an ex-Googler SWE myself and know that they're often
well-commented and descriptive of the RPC being called, which can be
useful information. Its not a big deal though, if you don't get many
requests to release them, don't bother.

Hi,

Could you release the .proto file for the Files API? I'd like to create my own implementation of the Files API in Java.

Thanks in Advance

[Anand K. Mistry]

Considering the Files API is experimental and may undergo significant changes at the lower level, I don't think it's appropriate to make the .proto file for that API available.
