[protobuf] ANN: ProtoStream - A NodeJS module to emit ProtoBuf messages from a stream, SAX-style.
This module uses ProtocolBuffers to de-frame protocol buffer messages within a (TCP) stream. https://github.com/chrisdew/protostream Hope it's useful to others too, Chris. -- You received this message because you are subscribed to the Google Groups Protocol Buffers group.

[protobuf] Where is the (meta) .proto file which describes .desc files?
Hi, Where is the (meta) .proto file which describes .desc files? I make .desc files with: protoc --descriptor_set_out=foo.desc --include_imports foo.proto. Am I correct in believing that the .desc files are in protobuf format? If so, where can I get the .proto file which describes their format? Thanks, Chris. P.S.

New issue 541 by matt.k...@undue.org: Double decode in
google.protobuf.text_format._CUnescape
http://code.google.com/p/protobuf/issues/detail?id=541
What steps will reproduce the problem?
print google.protobuf.text_format._CUnescape('\\x5c')
Traceback (most recent call last):
File stdin, line 1, in module
File
/usr/lib/python2.7/dist-packages/google/protobuf/text_format.py,
line 691, in _CUnescape
return result.decode('string_escape')
ValueError: Trailing \ in string
What is the expected output? What do you see instead?
The expected output is a single backslash. _CUnescape works if the
input
is instead given in octal:
print google.protobuf.text_format._CUnescape('\\134')
\
When the input is given in hex the escaped backslash is unescaped
_twice_,
once in the re.sub() and once in the str.decode().
I'm not using the trunk HEAD but I can see that the issue is still
present.

ByteString using N bytes from an
InputStream?http://groups.google.com/group/protobuf/t/1903436bc567615e
V.B. vidalborro...@gmail.com Aug 05 03:23PM -0700
Greetings all,
We are using version 2.5. What is the most efficient way (*i.e.*
single
copy operation, no extra byte arrays) to construct a ByteString from a
specific number of bytes in an InputStream? The various versions of
ByteString.readFrom() drain the stream completely, which is not what
we
need; any data past *N* bytes should remain in the stream. The
ByteString.readChunk() method looks like it will work if we simply
give it *
N* as the chunkSize parameter. Unfortunately, ByteString.readChunk()
is
declared private, so that method is not currently an option. Is there
another option that I just haven't found in the source code yet?
(Thanks for taking the time to read this question.)

How about create an wrapper InputStream that only reads N bytes from
the
original InputStream and provide the wrapper to BytesString.readFrom()?
V.B. vidalborro...@gmail.com Aug 05 09:28PM -0700
Hi Feng Xiao! Thanks for the response.
That's actually our backup plan. We were hoping to avoid it, though,
since the wrappers would each contain an extra copy of the data
internally.
Our ideal case is for the data to get copied in a single step directly
from
an InputStream to a ByteString with no intermediate copies along the
way.
Question: You would know best... Would the safety of ByteStrings be
preserved if the readChunk() method were to be made public? If so,
I'll
open a feature request on the issue tracker.

... Actually, I just now took a closer look at the readChunk() method.
Even
that method makes an internal copy, so it looks like readChunk() isn't
what
we are looking for after all. Hmmm.

Re: [protobuf] protobuf == SQL
I would use: protoc --descriptor_set_out=foo.desc --include_imports foo.proto to generate a description of the protocol in protobuf format. Then I would transform every message type into a table. If you want more information, email me at cms...@gmail.com All the best, Chris.

[protobuf] How do you use extensions across multiple .proto files?
How do you use extensions across multiple .proto files?
http://code.google.com/apis/protocolbuffers/docs/proto.html#extensions
see line: // This can even be in a different file.
I've tried:
protoc -I=./ --java_out=./ ./wrapper.proto ./attach.proto
but get the error: attach.proto:6:8:
Wrapper is not defined.
I feel I need some form of #include, but have not seen any
documentation for this.
Thanks,
Chris.
