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)
normalize() in Draft 1.06 (9 October 2002):
The normalize operation has been added; it reduces a number to a
canonical form. (This replaces the trim operator, which only
removed trailing fractional zeros.)
(version 1.45):
The max and min operations follow the rules in the current IEEE 754 revision draft:
if one operand is a quiet NaN and the other is number, then the number is always returned
if both operands are finite and equal in numerical value then an ordering is applied:
if the signs differ then max returns the operand with the positive sign and
min returns the operand with the negative sign; if the signs are the same then
the exponent is used to select the result.
version 2.39 of dectest.zip adds some new test files and because
some existing test files were getting skipped).
* Remove two docstrings which cluttered unittest's output.
* Simplify a for-loop with a list comprehension.
Document a nuance of super(). It is designed to work well with dotted
attribute lookup but not with equivalent implicit lookups using operators
or statements.
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.

* Expand the example to show a join.
* Mention the use case of I/O running concurrent with a computational
thread.
* Be a tad more forceful about recommending Queue over other approaches
to synchonization.
* Eliminate discussion around having a single interpreter. This is a
more advanced discussion that belongs in the library reference and
in a section on extending and embedding.
* Discuss representation error versus loss of significance.
* Document special values including qNaN, sNaN, +0, -0.
* Show the suprising display of non-normalized zero values.
path, as normalizing the path may alter the meaning of the path if it contains
symlinks.
Also add tests for infinite symlink loops and parent symlinks that need to be
resolved.
