Compilation was broken on Windows since the introduction of Advanced String Formatting.
Only PCBuild (vs9) was really tested.
Changes for older compilers were done manually.

The UnicodeWarning can be filtered as desired using + the warning framework, e.g. silenced completely, turned into an + exception, logged, etc. + + Note that compare operators other than equal and unequal will still + raise UnicodeDecodeError exceptions as they've always done. + +- Fix segfault when doing string formatting on subclasses of long. + +- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines + with new-style classes. + +- Fix bug related to __len__ functions returning negative values with + classic classes. + +- Patch #1538606, Fix __index__() clipping. There were some problems + discovered with the API and how integers that didn't fit into Py_ssize_t + were handled.

Fixing this problem required changing the .pyc + magic number. This means that .pyc files generated before 2.5c1 + will be regenerated. + +- Bug #1333982: string/number constants were inappropriately stored + in the byte code and co_consts even if they were not used, ie + immediately popped off the stack. + +- Fixed a reference-counting problem in property(). + + +>>>>>>> .merge-right.r60878 Library ------- |
