Apache Thrift

This is the work in progress to add Rust support to Thrift, see the branch dev-rust-thrift.

Current status:

Implemented:

• binary protocol
• buffered tcp transport
• client side
• simple server

Major limitations:

• no support for exceptions (issue #14)
• no support for constants (issue #12)
• limited support for container serialization (issue #13)
• no support for detecting unset fields (issue #29)

Introduction

Thrift is a lightweight, language-independent software stack with an associated code generation mechanism for RPC. Thrift provides clean abstractions for data transport, data serialization, and application level processing. The code generation system takes a simple definition language as its input and generates code across programming languages that uses the abstracted stack to build interoperable RPC clients and servers.

Thrift is specifically designed to support non-atomic version changes across client and server code.

For more details on Thrift's design and implementation, take a gander at the Thrift whitepaper included in this distribution or at the README.md files in your particular subdirectory of interest.

Acknowledgments

Thrift was inspired by pillar, a lightweight RPC tool written by Adam D'Angelo, and also by Google's protocol buffers.

Installation

If you are building from the first time out of the source repository, you will need to generate the configure scripts. (This is not necessary if you downloaded a tarball.) From the top directory, do:

./bootstrap.sh

Once the configure scripts are generated, thrift can be configured. From the top directory, do:

./configure

You may need to specify the location of the boost files explicitly. If you installed boost in /usr/local, you would run configure as follows:

./configure --with-boost=/usr/local

Note that by default the thrift C++ library is typically built with debugging symbols included. If you want to customize these options you should use the CXXFLAGS option in configure, as such:

./configure CXXFLAGS='-g -O2'
./configure CFLAGS='-g -O2'
./configure CPPFLAGS='-DDEBUG_MY_FEATURE'

To enable gcov required options -fprofile-arcs -ftest-coverage enable them:

./configure  --enable-coverage

Run ./configure --help to see other configuration options

Please be aware that the Python library will ignore the --prefix option and just install wherever Python's distutils puts it (usually along the lines of /usr/lib/pythonX.Y/site-packages/). If you need to control where the Python modules are installed, set the PY_PREFIX variable. (DESTDIR is respected for Python and C++.)

Make thrift:

make

From the top directory, become superuser and do:

make install

Note that some language packages must be installed manually using build tools better suited to those languages (at the time of this writing, this applies to Java, Ruby, PHP).

Look for the README.md file in the lib// folder for more details on the installation of each language library package.

Testing

There are a large number of client library tests that can all be run from the top-level directory.

      make -k check

This will make all of the libraries (as necessary), and run through the unit tests defined in each of the client libraries. If a single language fails, the make check will continue on and provide a synopsis at the end.

To run the cross-language test suite, please run:

      make cross

This will run a set of tests that use different language clients and servers.
