* Perform the code length check earlier.
* Eliminate the extra PyMem_Free() upon hitting an EXTENDED_ARG.
* Assert that the NOP count used in jump retargeting matches the NOPs
eliminated in the final step.
* Add an XXX note to indicate that more work is being to done to
handle linenotab with intervals > 255.
* Make a pass to eliminate NOPs. Produce code that is more readable,
more compact, and a tiny bit faster. Makes the peepholer more flexible
in the scope of allowable transformations.
* With Guido's okay, bumped up the magic number so that this patch gets
widely exercised before the alpha goes out.
files and not re-optimized upon import. Saves a bit of startup time while
still remaining decoupled from the rest of the compiler.
As a side benefit, handcoded bytecode is not run through the optimizer
when new code objects are created. Hopefully, a handcoder has already
created exactly what they want to have run.
(Idea suggested by Armin Rigo and Michael Hudson. Initially avoided
because of worries about compiler coupling; however, only the nexus
point needed to be moved so there won't be a conflict when the AST
branch is loaded.)
[ 1009560 ] Fix @decorator evaluation order
From the description:
Changes in this patch:
- Change Grammar/Grammar to require
newlines between adjacent decorators.
- Fix order of evaluation of decorators
in the C (compile.c) and python
(Lib/compiler/pycodegen.py) compilers
- Add better order of evaluation check
to test_decorators.py (test_eval_order)
- Update the decorator documentation in
the reference manual (improve description
of evaluation order and update syntax
description)
and the comment:
Used Brett's evaluation order (see
http://mail.python.org/pipermail/python-dev/2004-August/047835.html)
(I'm checking this in for Anthony who was having problems getting SF to
talk to him)
because GNU/k*BSD uses gnu pth to provide pthreads, but will also happen on any
system that does the same.
python fails to build because it doesn't detect gnu pth in pthread
emulation. See C comments in patch for details.

[ 1005248 ] new.code() not cleanly checking its arguments
using the result of new.code() can still destroy the sun, but merely
calling the function shouldn't any more.
I also rewrote the existing tests of new.code() to use vastly less
un-bogus arguments, and added tests for the previous insane behaviours.
hack: it would resize *interned* strings in-place! This occurred because
their reference counts do not have their expected value -- stringobject.c
hacks them. Mea culpa.
interning were not clear here -- a subclass could be mutable, for
example -- and had bugs. Explicitly interning a subclass of string
via intern() will raise a TypeError. Internal operations that attempt
to intern a string subclass will have no effect.
Added a few tests to test_builtin that includes the old buggy code and
verifies that calls like PyObject_SetAttr() don't fail. Perhaps these
tests should have gone in test_string.
[ 991812 ] PyArg_ParseTuple can miss errors with warnings as exceptions
as suggested in the report.
This is definitely a 2.3 candidate (as are most of the checkins I've
made in the last month...)
have differing refcount semantics. If anyone sees a prettier way to
acheive the same ends, then please go for it.
I think this is the first time I've ever used Py_XINCREF.
* Fixes an incorrect variable in a PyDict_CheckExact.
* Allow general mapping locals arguments for the execfile() function
and exec statement.
* Add tests.
PyImport_ReloadModule(): restore the module to sys.modules in error cases.
load_package(): semantic-neutral refactoring from an earlier stab at
this patch; giving it a common error exit made the code
easier to follow, so retaining that part.
_RemoveModule(): new little utility to delete a key from sys.modules.
