test_queue has failed occasionally for years, and there's more than one
cause.

The primary cause in the SF report appears to be that the test driver
really needs entirely different code for thread tests that expect to
raise exceptions than for thread tests that are testing non-exceptional
blocking semantics.  So gave them entirely different code, and added a
ton of explanation.

Another cause is that the blocking thread tests relied in several places
on the difference between sleep(.1) and sleep(.2) being long enough for
the trigger thread to do its stuff sot that the blocking thread could make
progress.  That's just not reliable on a loaded machine.  Boosted the 0.2's
to 10.0's instead, which should be long enough under any non-catastrophic
system conditions.  That doesn't make the test take longer to run, the 10.0
is just how long the blocking thread is *willing* to wait for the trigger
thread to do something.  But if the Queue module is plain broken, such
tests will indeed take 10 seconds to fail now.

For similar (heavy load) reasons, changed threaded-test termination to
be willing to wait 10 seconds for the signal thread to end too.

updates as bugfixes.

* Check the found object for a None value during a contains/has_key
  lookup.  Perhaps it will help the OP who is likely suffering from an
  occassional GC or threading object deletion after self.data is checked.

* Complete the previous patch by removing the unnecessary indirection
  for weak dict iterators.  Makes the code cleaner and more readable.

It's redundant, since no output is written anyway: DebugRunner doesn't
generate any output for failures and unexpected exceptions, and since
verbose=False, it won't generate any output for non-failures either.

constant defined by the module (except the test*() functions, which
should be integrated into test/test_doctest.py, anyway).

matches to be symmetric.  This makes the algorithm easier to understand.

appeared at the end of a line.  Repaired that.  Also noted that it's
too easy to provoke this implementation into requiring exponential
time, and especially when a test fails.  I'll replace the implementation
with an always-efficient one later.

error based on decorating with staticmethod too soon for the code to execute.
This meant that if the test didn't pass it just errored out.  Now if the test
doesn't pass it leads to a failure instead.

The make_head_and_body() function used a hardcoded value for the
<link> element for the index; this patch causes the proper output
filename to be captured during the transformation phase so it can be
used during the page assembly phase.

this (which are rather ugly, but it'll have to do until test_inspect gets a
major overhaul and a conversion to unittest). Thanks Simon Percivall!

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.)

Per Guido, sys.exitfunc will be kept around for backwards compatability
but atexit will become the one preferred way to do it.

[ 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)
