(Code contributed by Jiwon Seo.)
The documentation portion of the patch is being re-worked and will be
checked-in soon. Likewise, PEP 289 will be updated to reflect Guido's
rationale for the design decisions on binding behavior (as described in
in his patch comments and in discussions on python-dev).
The test file, test_genexps.py, is written in doctest format and is
meant to exercise all aspects of the the patch. Further additions are
welcome from everyone. Please stress test this new feature as much as
possible before the alpha release.

A variety of changes from Michael Hudson to get the compiler working
with 2.3. The primary change is the handling of SET_LINENO:
# The set_lineno() function and the explicit emit() calls for
# SET_LINENO below are only used to generate the line number table.
# As of Python 2.3, the interpreter does not have a SET_LINENO
# instruction. pyassem treats SET_LINENO opcodes as a special case.
A few other small changes:
- Remove unused code from pycodegen and pyassem.
- Fix error handling in parsermodule. When PyParser_SimplerParseString()
fails, it sets an exception with detailed info. The parsermodule
was clobbering that exception and replacing it was a generic
"could not parse string" exception. Keep the original exception.

bound.
When a Yield() node is visited, assign to the generator attribute of
the scope, not the visitor.
|
| |
|
|
|
| |
Fix bug in handling of statements like "l[x:y] = 2". The visitor was
treating this as assignments to l, x, and y!

(Hard to believe these were never handled before)
Add misc.mangle() that mangles based on the rules in compile.c.
XXX Need to test the corner cases
Update CodeGenerator with a class_name attribute bound to None. If a
particular instance is created within a class scope, the instance's
class_name is bound to that class's name.
Add mangle() method to CodeGenerator that mangles if the class_name
has a class_name in it.
Modify the FunctionCodeGenerator family to handle an extra argument--
the class_name.
Wrap all name ops and attrnames in calls to self.mangle()

Evan Simpson's fix. And his explanation:
If you defined two nested functions in a row that refer to the
same non-global variable, the second one will be generated as
though the variable were global.

Fix func arg processing to handle args in tuples.
In test code, skip names beginning with '.'.

Add mangling support
Add get_children() and add_child() methods to Scope
Skip nodes when If test is a false constant
Add test code that checks results against symtable module
