Purify) being caused by a bug in the readline library. Nothing we can
do about it.
Cause: readline_initialize_everything() throws away the return value
from rl_read_init_file(), but that happens to be the last reference to
a dynamically allocated char*.
decompressor object. This required adding a flag to the struct which is
true if initialisation was completed; on object destruction, deflateEnd()
is only called if the flag is true.
NOTE: There is still a bug of some sort in the behavior of zlib. In
at least one case, inflate returns Z_OK (which is typically
interpreted to mean that more output space is needed) when it has
finished inflating a buffer. This has been reported as a bug to the
zlib maintainers; we may need to change the Python interface.

Caused by using just 'char' where 'unsigned char' should have been used.
But IMHO, this problem really reveals an annoyance in Python's
makesetup. makesetup puts the global include directories "$(INCLUDEPY)
$(EXECINCLUDEPY)" in front of the directories defined by the module in
Setup. Therefore global (potentially older) header files are preferred
over the ones set by the module, which makes it hard to compile new
versions of modules when the old versions are installed. AFAIK, the
other way around is common practice for most other software.
This patch to makesetup would be an potential fix for this problem,
though I don't know if it breaks anything else.
- New copyright. (Open source)
- Added new protocol for binary string pickles that
takes out unneeded puts:
p=Pickler()
p.dump(x)
p.dump(y)
thePickle=p.getvalue()
This has little or no impact on pickling time, but
often reduces unpickling time and pickle size, sometimes
significantly.
- Changed unpickler to use internal data structure instead
of list to reduce unpickling times by about a third.
- Many cleanups to get rid of obfuscated error handling
involving 'goto finally' and status variables.
- Extensive reGuidofication. (formatting :)
- Fixed binary floating-point pickling bug. 0.0 was not
pickled correctly.
- Now use binary floating point format when saving
floats in binary mode.
- Fixed some error message spelling error.
- New copyright. (Open source)
- Fixed problem in seek method. The seek method should (and now does)
fill with nulls when seeking past the end of the "file".
