Special changes were required to enable PyPy +support because PyPy has a non-deterministic garbage collector that does +not rely on reference counting unlike the CPython garbage collector. + +The changes to the codebase involved changes to the library code as well +as changes to the tests and scripts in the test infrastructure which +resulted in both the library as well as the testing infrastructure being +Python 3.x and PyPy compatible. + +The list of merged commits, as of 22.08.2016 23:59 CEST, is summarized +here for the perusal of those interested: + +- [Enable py35 and py36 testing](https://github.com/grpc/grpc/commit/c478214e475e103c5cdf477f0adc18bba2c03903) +- [Make testing toolchain python 3.x compliant](https://github.com/grpc/grpc/commit/0589e533cd65a2ca9e0e610cc1b284d016986572) +- [Add .idea folder to .gitignore](https://github.com/grpc/grpc/commit/365ef40947e22b5438a63f123679ae9a5474c47c) +- [Fix the ThreadPoolExecutor: max_workers can't be 0](https://github.com/grpc/grpc/commit/de84d566b8fad6808e5263a25a17fa231cb5713c) +- [Add PyPy to testing toolchain](https://github.com/grpc/grpc/commit/2135a1b557f8b992186d5317cb767ac4dbcdfe5c) +- [Switch init/shutdown: lib-wide -> per-object](https://github.com/grpc/grpc/commit/9eedb4ffd74aed8d246a07f8007960b2bc167f55) +- [Skip test run if running with pypy](https://github.com/grpc/grpc/commit/f0f58e68738abbc317f7f449c5104f7fbbff26bd) + +The list of unmerged pull requests is as follows: + +- [Add PyPy 5.3.1 to dockerfile and template](https://github.com/grpc/grpc/pull/7763) +- [remove skipIf from TypeSmokeTest (issue 7672)](https://github.com/grpc/grpc/pull/7831) + +The list of tasks that have pending unsubmitted pull requests is as follows: + +- Modify run_tests.py to enable testing of new languages without + affecting old branches. + + +Project Details +=============== +- Title: GRPC Python compatibility support +- Student: [Siddharth Shukla](https://github.com/thunderboltsid) +- Mentors: [Nathaniel Manista](https://github.com/nathanielmanistaatgoogle), [Masood Malekghassemi](https://github.com/soltanmm) +- Duration: May 23 - August 23 +- Hat tip: [Ken Payson](https://github.com/kpayson64), [Jan Tattermusch](https://github.com/jtattermusch), [Nicolas Noble](https://github.com/nicolasnoble) + + |
