Add nonlocal_stmt to Grammar and Nonlocal node to AST. They both
parallel the definitions for globals. The symbol table treats
variables declared as nonlocal just like variables that are free
implicitly.
This change is missing the language spec changes, but makes some
decisions about what the spec should say via the unittests. The PEP
is silent on a number of decisions, so we should review those before
claiming that nonlocal is complete.
Thomas Wouters made the grammer and ast changes. Jeremy Hylton added
the symbol table changes and the tests. Pete Shinners and Neal
Norwitz helped review the code.

Update the encoding package's search function to use absolute imports when
calling __import__. This helps make the expected search locations for encoding
modules be more explicit.
One could use an explicit value for __path__ when making the call to __import__
to force the exact location searched for encodings. This would give the most
strict search path possible if one is worried about malicious code being
imported. The unfortunate side-effect of that is that if __path__ was modified
on 'encodings' on purpose in a safe way it would not be picked up in future
__import__ calls.

Add parameter sys_version to _sys_version().
Change the cache for _sys_version() to take the parameter into account.
Add support for parsing the IronPython 1.0.1 sys.version value - even
though it still returns '1.0.0'; the version string no longer includes
the patch level.

Add Python implementation to the machine details.
Pretty-print the Python version used for running PyBench.
Let the user know when calibration has finished.
[ 1563844 ] pybench support for IronPython:
Simplify Unicode version detection.
Make garbage collection and check interval settings optional if
the Python implementation doesn't support thess (e.g. IronPython).

Merged changes from standalone version 2.3.3. This should probably all be
merged into the 2.5 maintenance branch:
- self->statement was not checked while fetching data, which could
lead to crashes if you used the pysqlite API in unusual ways.
Closing the cursor and continuing to fetch data was enough.
- Converters are stored in a converters dictionary. The converter name
is uppercased first. The old upper-casing algorithm was wrong and
was replaced by a simple call to the Python string's upper() method
instead.
-Applied patch by Glyph Lefkowitz that fixes the problem with
subsequent SQLITE_SCHEMA errors.
- Improvement to the row type: rows can now be iterated over and have a keys()
method. This improves compatibility with both tuple and dict a lot.
- A bugfix for the subsecond resolution in timestamps.
- Corrected the way the flags PARSE_DECLTYPES and PARSE_COLNAMES are
checked for. Now they work as documented.
- gcc on Linux sucks. It exports all symbols by default in shared
libraries, so if symbols are not unique it can lead to problems with
symbol lookup. pysqlite used to crash under Apache when mod_cache
was enabled because both modules had the symbol cache_init. I fixed
this by applying the prefix pysqlite_ almost everywhere. Sigh.

number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
http://mail.python.org/pipermail/python-dev/2006-April/064051.html
Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:
test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs
test_multibytecodec
This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.
- IMPORT_NAME takes an extra argument from the stack: the relativeness of
the import. Only passed to __import__ when it's not -1.
- __import__() takes an optional 5th argument for the same thing; it
__defaults to -1 (old semantics: try relative, then absolute)
- 'from . import name' imports name (be it module or regular attribute)
from the current module's *package*. Likewise, 'from .module import name'
will import name from a sibling to the current module.
- Importing from outside a package is not allowed; 'from . import sys' in a
toplevel module will not work, nor will 'from .. import sys' in a
(single-level) package.
- 'from __future__ import absolute_import' will turn on the new semantics
for import and from-import: imports will be absolute, except for
from-import with dots.
Includes tests for regular imports and importhooks, parser changes and a
NEWS item, but no compiler-package changes or documentation changes.
This was started by Mike Bland and completed by Guido
(with help from Neal).
This still needs a __future__ statement added;
Thomas is working on Michael's patch for that aspect.
There's a small amount of code cleanup and refactoring
in ast.c, compile.c and ceval.c (I fixed the lltrace
behavior when EXT_POP is used -- however I had to make
lltrace a static global).
breaks the parser module, because it adds the if/else construct as well as
two new grammar rules for backward compatibility. If no one else fixes
parsermodule, I guess I'll go ahead and fix it later this week.
The TeX code was checked with texcheck.py, but not rendered. There is
actually a slight incompatibility:
>>> (x for x in lambda:0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: iteration over non-sequence
changes into
>>> (x for x in lambda: 0)
File "<stdin>", line 1
(x for x in lambda: 0)
^
SyntaxError: invalid syntax
Since there's no way the former version can be useful, it's probably a
bugfix ;)
Strip off leading dots and slash so the generated files are the same regardless
of whether you configure in the checkout directory or build.
If anyone configures in a different directory, we might want a cleaner
approach using os.path.*(). Hopefully this is good enough.
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.
The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.
