This serves to made the context representation more useful (the names in
match the names out).
Removed the link to ReXX. That document did not shed add anything to
information already in the spec.
Further tighten the public API to improve usability:
* Emax and Emin are set through Context(). Their defaults are set in the
DefaultContext, so there is no need to expose DEFAULT_MAX_EXPONENT
and DEFAULT_MIN_EXPONENT.
* The string functions isnan() and isinfinity() were only used internal to
the module and were not among the test cases. External use cases are
served by the Decimal constructor. So, made these private.
and format the warning similarly to an exception for both that check and for
warnings raised in the subprocess.

* delete temporary globals immediately after use
* move a global into a class variable
* Rename BasicDefaultContext and ExtendedDefaultContext
to BasicContext and ExtendedContext.
Added error checking to log() to check that level is an integer, and raise a TypeError if not (as long as raiseExceptions is set).
Minor documentation corrections.
* Added test for pickling contexts
* Renamed ExceptionList to Signals (to match wording in the spec)
* Simplified Context constructor by allowing flags=None to automatically
generate a zeroed-out flags dictionary.
* inlined _convertString() which was used only once
* _rounding_decision is private, so excluded its contants from __all__.
* added an XXX comment with concerns about subclassing signals results in
a deviation from the spec (maybe important, maybe not).
* Taught the test_suite to determine its own directory (modeled after code
in regrtest.py). Enables it to be run when the current directory is not
the test directory.
* Added a clear_flags() method to the Context API to make it easier to do
a common operation with flags.
* Fixed the trap_enablers defaults in BasicDefaultContext to match the spec.
during interpreter shutdown instead of masking it with another traceback about
accessing a NoneType when trying to print the exception out in the first place.
Closes bug #754449 (using patch #954922).

* When enumerating the Python versions found, also remember the HKEY
they were found under.
* When installing, if Python was installed under HKCU, we will too.
If Python was installed under HKLM, we check the permissions of
the current user, and install where we can.
* The "root" key we use is a global variable - all registry setting and
delete functions use this global rather than a hardcoded HKLM.
* A new entry is written to the install log, indicating the key we used.
Uninstallation is based on this key.
* 'tempnam()' is used rather than 'tmpnam()' - 'tmpnam' creates a temp
file on the root of the current drive, and if this is readonly would
explain the 'freopen' errors occasionally reported. 'tempnam'
creates the temp file in the %TEMP% directory.
- weakref.ref and weakref.ReferenceType will become aliases for each
other
- weakref.ref will be a modern, new-style class with proper __new__
and __init__ methods
- weakref.WeakValueDictionary will have a lighter memory footprint,
using a new weakref.ref subclass to associate the key with the
value, allowing us to have only a single object of overhead for each
dictionary entry (currently, there are 3 objects of overhead per
entry: a weakref to the value, a weakref to the dictionary, and a
function object used as a weakref callback; the weakref to the
dictionary could be avoided without this change)
- a new macro, PyWeakref_CheckRefExact(), will be added
- PyWeakref_CheckRef() will check for subclasses of weakref.ref
This closes SF patch #983019.
table' of the dll, to make sure that the dll really was build for the
correct Python version. It does this by looking for an entry
'pythonXY.dll' (X.Y is the Python version number).
The code now checks the size of the dll's import table before reading
entries from it. Before this patch, the code crashed trying to read
the import table when the size was zero (as in Win2k's wmi.dll, for
example).
Look for imports of 'pythonXY_d.dll' in a debug build instead of
'pythonXY.dll'.
Fixes SF 951851: Crash when reading "import table" of certain windows dlls.
Already backported to the 2.3 branch.
The builtin eval() function now accepts any mapping for the locals argument.
Time sensitive steps guarded by PyDict_CheckExact() to keep from slowing
down the normal case. My timings so no measurable impact.
char *`` instead of just ``char *``. Also added the mentioning of "const" in
some places where it was left out even when the signature already stated the
fact.
Closes bug #980925.
[ 924301 ] A leak case with cmd.py & readline & exception
by ensuring that the readline completion function is always reset
even in the case of an exception being raised. As a bonus, this
makes the documentation for pre & postloop accurate again.
