• STINGER directory structure and CMakeLists.txt have changed to support parallel build
  • lib/ directory houses the STINGER libraries
  • src/ directory houses the supporting binaries
  • external/ directory houses external dependencies
  • Can now build with make -j8 after performing cmake in the build directory
• Prevent remapping of graph on each batch sent over protobuf (fixing a memory leak)
• STINGER management web interface merged in
  • Hosted under the util/management directory
  • Flask API merged with the management console flask API and is now in util/flask
  • Old STINGER web interface now in util/graph_explorer
• Flask API improvements
  • Fix for empty batches
  • Optimization on sending batches
  • Flask is fully aware of directedness and is consistent with STINGER
  • Added a Swagger UI documentation to the Flask API
  • Added requirements.txt for easy dependency installation (Use pip install -r requirements.txt)
• PageRank changes
  • A PageRank that works on a directed graph was added
  • A PageRank that works over a subset of vertices was added. A JSON RPC call was also added to call this method
• stinger_alg
  • Most algorithms are now in the lib/stinger_alg directory
  • Algorithms are now uniformly used between the client applications and the JSON RPC server
• netflow_stream
  • Bug fixes
• Adamic Adar
  • Bug fix to the calculation to now be right for undirected graphs
• Numerous whitespace fixes (removing tabs)
• Refactored array_to_json_monolithic to reduce code redundancy
• Added type filtering to JSON requests on get_data_array_*
• Betweenness Centrality
  • Uses a BFS style solving approach now that is compatible with directed graphs and has a near identical runtime to old version
• Changed the default STINGER to be 3/4 of the specified memory size
• Added a configuration file option to the server that uses libconfig
  • Can be used to specify number of vertices, edge types, memory size, etc.
  • Can pre-map edge type strings and vertex type strings
  • stinger_new_full and stinger_shared_new_full API changed to support a robust config parameter
• Traversal macros had several bugs that were squashed
• Updated Readme.md to reference config file changes
• Added Testing infrastructure
  • Using googletest for tests
  • Added rule to CMake for make check that runs all unit tests
  • Updated travis.yml to automatically run make check on any new PRs
• travis.yml
  • Fixed travis to run in a docker container allowing for faster CI tests
