Protocol Buffers - Google's data interchange format
Copyright 2008 Google Inc.
This directory contains the Python Protocol Buffers runtime library.
Normally, this directory comes as part of the protobuf package, available
from:
https://developers.google.com/protocol-buffers/
The complete package includes the C++ source code, which includes the
Protocol Compiler (protoc). If you downloaded this package from PyPI
or some other Python-specific source, you may have received only the
Python part of the code. In this case, you will need to obtain the
Protocol Compiler from some other source before you can use this
package.
Development Warning
===================
The Python implementation of Protocol Buffers is not as mature as the C++
and Java implementations. It may be more buggy, and it is known to be
pretty slow at this time. If you would like to help fix these issues,
join the Protocol Buffers discussion list and let us know!
Installation
============
1) Make sure you have Python 2.4 or newer. If in doubt, run:
$ python -V
2) If you do not have setuptools installed, note that it will be
downloaded and installed automatically as soon as you run setup.py.
If you would rather install it manually, you may do so by following
the instructions on this page:
http://peak.telecommunity.com/DevCenter/EasyInstall#installation-instructions
3) Build the C++ code, or install a binary distribution of protoc. If
you install a binary distribution, make sure that it is the same
version as this package. If in doubt, run:
$ protoc --version
4) Build and run the tests:
$ python setup.py build
$ python setup.py google_test
If you want to test c++ implementation, run:
$ python setup.py test --cpp_implementation
If some tests fail, this library may not work correctly on your
system. Continue at your own risk.
Please note that there is a known problem with some versions of
Python on Cygwin which causes the tests to fail after printing the
error: "sem_init: Resource temporarily unavailable". This appears
to be a bug either in Cygwin or in Python:
http://www.cygwin.com/ml/cygwin/2005-07/msg01378.html
We do not know if or when it might me fixed. We also do not know
how likely it is that this bug will affect users in practice.
5) Install:
$ python setup.py install
or:
$ python setup.py install --cpp_implementation
This step may require superuser privileges.
NOTE: To use C++ implementation, you need to install C++ protobuf runtime
library of the same version and export the environment variable before this
step. See the "C++ Implementation" section below for more details.
Usage
=====
The complete documentation for Protocol Buffers is available via the
web at:
https://developers.google.com/protocol-buffers/
C++ Implementation
==================
The C++ implementation for Python messages is built as a Python extension to
improve the overall protobuf Python performance.
To use the C++ implementation, you need to:
1) Install the C++ protobuf runtime library, please see instructions in the
parent directory.
2) Export an environment variable:
$ export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=cpp
$ export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION_VERSION=2
You need to export this variable before running setup.py script to build and
install the extension. You must also set the variable at runtime, otherwise
the pure-Python implementation will be used. In a future release, we will
change the default so that C++ implementation is used whenever it is available.
It is strongly recommended to run `python setup.py test` after setting the
variable to "cpp", so the tests will be against C++ implemented Python
messages.

"""Provides DescriptorPool to use as a container for proto2 descriptors.
The DescriptorPool is used in conjection with a DescriptorDatabase to maintain
a collection of protocol buffer descriptors for use when dynamically creating
message types at runtime.
For most applications protocol buffers should be used via modules generated by
the protocol buffer compiler tool. This should only be used when the type of
protocol buffers used in an application or library cannot be predetermined.
Below is a straightforward example on how to use this class:
pool = DescriptorPool()
file_descriptor_protos = [ ... ]
for file_descriptor_proto in file_descriptor_protos:
pool.Add(file_descriptor_proto)
my_message_descriptor = pool.FindMessageTypeByName('some.package.MessageType')
The message descriptor can be used in conjunction with the message_factory
module in order to create a protocol buffer class that can be encoded and
decoded.
If you want to get a Python class for the specified proto, use the
helper functions inside google.protobuf.message_factory
directly instead of this class.

buffer field types which need extra maintenance. Currently these categories
are:

composite (e.g. they are of simple types like int32, string, etc).
- Repeated composite fields - Repeated fields which are composite. This

"""Code for decoding protocol buffer primitives.
This code is very similar to encoder.py -- read the docs for that module first.
A "decoder" is a function with the signature:
Decode(buffer, pos, end, message, field_dict)
The arguments are:
buffer: The string containing the encoded message.
pos: The current position in the string.
end: The position in the string where the current message ends. May be
less than len(buffer) if we're reading a sub-message.
message: The message object into which we're parsing.
field_dict: message._fields (avoids a hashtable lookup).
The decoder reads the field and stores it into field_dict, returning the new
buffer position. A decoder for a repeated field may proactively decode all of
the elements of that field, if they appear consecutively.
Note that decoders may throw any of the following:
IndexError: Indicates a truncated message.
struct.error: Unpacking of a fixed-width field failed.
message.DecodeError: Other errors.
Decoders are expected to raise an exception if they are called with pos > end.
This allows callers to be lax about bounds checking: it's fineto read past
"end" as long as you are sure that someone else will notice and throw an
exception later on.
Something up the call stack is expected to catch IndexError and struct.error
and convert them to message.DecodeError.
Decoders are constructed using decoder constructors with the signature:
MakeDecoder(field_number, is_repeated, is_packed, key, new_default)
The arguments are:
field_number: The field number of the field we want to decode.
is_repeated: Is the field a repeated field? (bool)
is_packed: Is the field a packed field? (bool)
key: The key to use when looking up the field within field_dict.
(This is actually the FieldDescriptor but nothing in this
file should depend on that.)
new_default: A function which takes a message object as a parameter and
returns a new instance of the default value for this field.
(This is called for repeated fields and sub-messages, when an
instance does not already exist.)
As with encoders, we define a decoder constructor for every type of field.
Then, for every field of every message class we construct an actual decoder.
That decoder goes into a dict indexed by tag, so when we decode a message
we repeatedly read a tag, look up the corresponding decoder, and invoke it.

"""Code for encoding protocol message primitives.
Contains the logic for encoding every logical protocol field type
into one of the 5 physical wire types.
This code is designed to push the Python interpreter's performance to the
limits.
The basic idea is that at startup time, for every field (i.e. every
FieldDescriptor) we construct two functions: a "sizer" and an "encoder". The
sizer takes a value of this field's type and computes its byte size. The
encoder takes a writer function and a value. It encodes the value into byte
strings and invokes the writer function to write those strings. Typically the
writer function is the write() method of a cStringIO.
We try to do as much work as possible when constructing the writer and the
sizer rather than when calling them. In particular:
* We copy any needed global functions to local variables, so that we do not need
to do costly global table lookups at runtime.
* Similarly, we try to do any attribute lookups at startup time if possible.
* Every field's tag is encoded to bytes at startup, since it can't change at
runtime.
* Whatever component of the field size we can compute at startup, we do.
* We *avoid* sharing code if doing so would make the code slower and not sharing
does not burden us too much. For example, encoders for repeated fields do
not just call the encoders for singular fields in a loop because this would
add an extra function call overhead for every loop iteration; instead, we
manually inline the single-value encoder into the loop.
* If a Python function lacks a return statement, Python actually generates
instructions to pop the result of the last statement off the stack, push
None onto the stack, and then return that. If we really don't care what
value is returned, then we can save two instructions by returning the
result of the last statement. It looks funny but it helps.
* We assume that type and bounds checking has happened at a higher level.

(b) The message's cached byte size became dirty -- i.e. the message was
modified for the first time after a previous call to ByteSize().
Therefore the parent should also mark its byte size as dirty.
Note that (a) implies (b), since new objects start out with a client cached
size (zero). However, we document (a) explicitly because it is important.
Modified() will *only* be called in response to one of these two events --
not every time the sub-message is modified.
Note that if the listener's |dirty| attribute is true, then calling
Modified at the moment would be a no-op, so it can be skipped. Performance-
sensitive callers should check this attribute directly before calling since
it will be true most of the time.

implementation, so that proto2 services can be used on top of a variety
of implementations. Starting with version 2.3.0, RPC implementations should
not try to build on these, but should instead provide code generator plugins
which generate code specific to the particular RPC implementation. This way
the generated code can be more appropriate for the implementation in use
and can avoid unnecessary layers of indirection.

at the module, class, and instance level while preserving proper
inheritance. It will not stub out C types however unless that has been
explicitly allowed by the type.

classmethod of obj.
Notes:
- If obj is an instance, then it is its class that will actually be
stubbed. Note that the method Set() does not do that: if obj is
an instance, it (and not its class) will be stubbed.
- The stubbing is using the builtin getattr and setattr. So, the __get__
and __set__ will be called when stubbing (TODO: A better idea would
probably be to manipulate obj.__dict__ instead of getattr() and
setattr()).
Raises AttributeError if the attribute cannot be found.
