| | | | | | | | | | | | | | Initial patch by Merlijn van Deen. I've added a few unrelated docstring fixes in the patch while I was at it, which makes the documentation for pickle a bit more consistent.

* | Remove explicit empty tuple reuse in cpickle.Alexandre Vassalotti2013-11-281-12/+6
| | | | | | | | | | | | PyTuple_New(0) always returns the same empty tuple from its free list anyway, so we are not saving much here. Plus, the code where this was used is on uncommon run paths.
* | Remove the tuple reuse optimization in _Pickle_FastCall.Alexandre Vassalotti2013-11-281-30/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I have noticed a race-condition occurring on one of the buildbots because of this optimization. The function called may release the GIL which means multiple threads may end up accessing the shared tuple. I could fix it up by storing the tuple to the Pickler and Unipickler object again, but honestly it really not worth the trouble. I ran many benchmarks and the only time the optimization helps is when using a fin-memory file, like io.BytesIO on which reads are super cheap, combined with pickle protocol less than 4. Even in this contrived case, the speedup is a about 5%. For everything else, this optimization does not provide any noticable improvements.
* | Encapsulate cpickle global state in a dedicated object.Alexandre Vassalotti2013-11-281-270/+426
| | | | | | | | | | This implements PEP 3121 module finalization as well. This change does not cause any significant impact on performance.
* | Combine the FastCall functions in cpickle.Alexandre Vassalotti2013-11-271-90/+42
| | | | | | | | | | I fixed the bug that was in my previous attempt of this cleanup. I ran the full test suite to verify I didn't introduce any obvious bugs.

* | Use Clinic to process arguments in cpickle.Alexandre Vassalotti2013-11-241-257/+672
| | | | | | | | | | | | This doesn't make any functional changes to the exisiting implementation. The conversion did help however uncover documentation bugs. The best thing about this conversion is less C code to maintain by hand.

* | Make framing optional in pickle protocol 4.Alexandre Vassalotti2013-11-241-126/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will allow us to control in the future whether to use framing or not. For example, we may want to turn it off for tiny pickle where it doesn't help. The change also improves performance slightly: ### fastpickle ### Min: 0.608517 -> 0.557358: 1.09x faster Avg: 0.798892 -> 0.694738: 1.15x faster Significant (t=3.45) Stddev: 0.17145 -> 0.12704: 1.3496x smaller Timeline: http://goo.gl/3xQE1J ### pickle_dict ### Min: 0.669920 -> 0.615271: 1.09x faster Avg: 0.733633 -> 0.645058: 1.14x faster Significant (t=5.05) Stddev: 0.12041 -> 0.02961: 4.0662x smaller Timeline: http://goo.gl/LpLSXI ### pickle_list ### Min: 0.397583 -> 0.368112: 1.08x faster Avg: 0.412784 -> 0.397223: 1.04x faster Significant (t=2.78) Stddev: 0.01518 -> 0.03653: 2.4068x larger Timeline: http://goo.gl/v39E59 ### unpickle_list ### Min: 0.692935 -> 0.594870: 1.16x faster Avg: 0.730012 -> 0.628395: 1.16x faster Significant (t=17.76) Stddev: 0.02720 -> 0.02995: 1.1012x larger Timeline: http://goo.gl/2P9AEt The following not significant results are hidden, use -v to show them: fastunpickle.
