* Use PyDict_GetItemWithError instead of PyDict_GetItem in cpickle.Alexandre Vassalotti2013-11-291-12/+35

* 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.
* | Closes #19786: tracemalloc, remove the arbitrary limit of 100 framesVictor Stinner2013-11-271-21/+34
| | | | | | | | | | | | | | | | The limit is now 178,956,969 on 64 bit (it is greater on 32 bit because structures are smaller). Use int instead of Py_ssize_t to store the number of frames to have smaller traceback_t objects.

| | | | | | | | | | 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.

| | | | | | | | | | | | | | | | Regression introduced by the implementation of the PEP 446 (non-inheritable file descriptors by default). master_fd must be set non-inheritable after the creation of the slave_fd, otherwise grantpt(master_fd) fails with EPERM (errno 13).

| | | | | | | | | | | | 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.

For example, we may want to turn it off for tiny pickle where it doesn't help.
