* Issue #23611: Serializing more "lookupable" objects (such as unbound methodsSerhiy Storchaka2015-03-311-15/+18

* Issue #18473: Fixed 2to3 and 3to2 compatible pickle mappings.Serhiy Storchaka2015-03-311-2/+2
| | | | | | | | Fixed ambigious reverse mappings. Added many new mappings. Import mapping is no longer applied to modules already mapped with full name mapping. Added tests for compatible pickling and unpickling and for consistency of _compat_pickle mappings.

* Issue #6784: Strings from Python 2 can now be unpickled as bytes objects.Alexandre Vassalotti2013-12-071-29/+42
| | | | | | | 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.

* | Make framing optional in pickle protocol 4.Alexandre Vassalotti2013-11-241-71/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Make C and Python implementations of pickle load STRING opcodes the same way.Alexandre Vassalotti2013-04-161-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | The C version tried to remove trailing whitespace between the last quote and the newline character. I am not sure why it had this because pickle never generated such pickles---for this to happen repr(some_string) would need to return trailing whitespace. It was maybe there to make it easier for people to write pickles in text editors. Anyhow, the Python version doesn't do this so there is no point keeping this around anymore. Also, I've changed the exception raised when a bad pickle is encountered. Again this unlikely to make much difference to anyone though it does make testing slightly nicer for us.
