on each iteration. I'm not positive this is the best way to handle
this. I'm also not sure that there aren't other cases where
the lnotab is generated incorrectly. It would be great if people
that use pdb or tracing could test heavily.
Also:
* Remove dead/duplicated code that wasn't used/necessary
because we already handled the docstring prior to entering the loop.
* add some debugging code into the compiler (#if 0'd out).
Patch by Douglas Greiman.
The test_run_abort() testcase produces a core file on Unix systems,
even though the test is successful. This can be confusing or alarming
to someone who runs 'make test' and then finds that the Python
interpreter apparently crashed.
These problems may mask more important, real problems.
One or both methods are known to fail on: Solaris, OpenBSD, Debian, Ubuntu.
They pass on Windows and some Linux boxes.

inspect.py, and pydoc.py. Specifically, this allows for querying the type of
an object against these built-in C types and more importantly, for getting
their docstrings printed in the interactive interpreter's help() function.
This patch includes a new built-in module called _types which provides
definitions of getset and member descriptors for use by the types.py module.
These types are exposed as types.GetSetDescriptorType and
types.MemberDescriptorType. Query functions are provided as
inspect.isgetsetdescriptor() and inspect.ismemberdescriptor(). The
implementations of these are robust enough to work with Python implementations
other than CPython, which may not have these fundamental types.
The patch also includes documentation and test suite updates.
I commit these changes now under these guiding principles:
1. Silence is assent. The release manager has not said "no", and of the few
people that cared enough to respond to the thread, the worst vote was "0".
2. It's easier to ask for forgiveness than permission.
3. It's so dang easy to revert stuff in svn, that you could view this as a
forcing function. :)
Windows build patches will follow.
When a node number disagrees, keep track of all sources & the
node numbers they reported, and stick all that in the error message.
Changed all callers to supply a non-empty "source" argument; made
the "source" argument non-optional.
On my box, test_uuid still fails, but with the less confusing output:
AssertionError: different sources disagree on node:

from source 'getnode2', node was 00038a000015

The latter is overwhelming most likely, but not guaranteed,

that a 2.93 sec audio file will always take 3.1 sec (as it did on the

Moved the code for _PyThread_CurrentFrames() up, so it's no longer
in a huge "#ifdef WITH_THREAD" block (I didn't realize it /was/ in
one).
Changed test_sys's test_current_frames() so it passes with or without
thread supported compiled in.
Note that test_sys fails when Python is compiled without threads,
but for an unrelated reason (the old test_exit() fails with an
indirect ImportError on the `thread` module). There are also
other unrelated compilation failures without threads, in extension
modules (like ctypes); at least the core compiles again.
Do we really support --without-threads? If so, there are several
problems remaining.
of values in the time tuple passed in. Unfortunately people came to rely on
undocumented behaviour of setting unneeded values to 0, regardless of if it was
within the valid range. Now those values force the value internally to the
minimum value when 0 is passed in.
The hppa ubuntu box sometimes hangs forever in these tests. My guess
is that the wait is failing for some reason. Use WNOHANG, so we won't
wait until the buildbot kills the test suite.
I haven't been able to reproduce the failure, so I'm not sure if
this will help or not. Hopefully, this change will cause the test
to fail, rather than hang. That will be better since we will get
the rest of the test results. It may also help us debug the real problem.
*** The reason this originally failed was because there were many
zombie children outstanding before rev 47158 cleaned them up.
There are still hangs in test_subprocess that need to be addressed,
but that will take more work. This should close some holes.
str() or repr()) would work, just not multi-value tuples. Probably not a

should be called from regrtest instead?). This will hopefully prevent
some of the unexplained failures in the buildbots (hppa and alpha)
during tests that spawn children. The problems were not reproducible.
There were many zombies that remained at the end of several tests.
In the worst case, this shouldn't cause any more problems,
though it may not help either. Time will tell.
(modified patch by Sam Ruby; changed to use separate REs for start and end
tags to reduce matching cost for end tags; extended tests; updated to avoid
breaking previous changes to support IPv6 addresses in unquoted attribute

consistent with os.wait() returning immediately because some other
subprocess had previously exited; the test suite then immediately
tries to lock the mailbox and gets an error saying it's already
locked.
To fix this, do a waitpid() so the test suite only continues once
the intended child process has exited.

- cleaned up tests of character and entity reference decoding so the

both a subclass of Warning and a subclass of types.ClassType. The latter is no

Closes bug #1510580. Thanks to AMK for the test.
The problem of checking too eagerly for recursive calls is the
following: if a RuntimeError is caused by recursion, and if code needs
to normalize it immediately (as in the 2nd test), then
PyErr_NormalizeException() needs a call to the RuntimeError class to
instantiate it, and this hits the recursion limit again... causing
PyErr_NormalizeException() to never finish.
Moved this particular recursion check to slot_tp_call(), which is not
involved in instantiating built-in exceptions.
Backport candidate.

means using the 'message' attribute won't work (until Py3K comes around),
and so one must grab from 'arg' to get the error number.
os.environ (setting envar COLUMNS), which at least caused
test_float_default() to fail if the tests were run more than once.
This repairs the test_optparse -R failures Neal reported on
python-dev. It also explains some seemingly bizarre test_optparse
failures we saw a couple weeks ago on the buildbots, when
test_optparse failed due to test_file failing to clean up after
itself, and then test_optparse failed in an entirely different
way when regrtest's -w option ran test_optparse a second time.
It's now obvious that make_parser() permanently changing os.environ
was responsible for the second half of that.

of this test. It probably still requires more disk space
than most buildbots have, and in any case is still so
intrusive that if we don't find another way to test this I'm
taking my buildbot offline permanently ;-)
This will hopefully get the buildbots to pass. Not sure this
test will be feasible or even work. But everything is red now,
so it can't get much worse.

when running with -O.
test_simple_validation_error still fails under -O. That appears to be because
wsgiref's validate.py uses `assert` statements all over the place to check
arguments for sanity. That should all be changed (it's not a logical error
in the software if a user passes bogus arguments, so this isn't a reasonable
use for `assert` -- checking external preconditions should generally raise
ValueError or TypeError instead, as appropriate).
a search path setup, some of these hosts resolve to the wrong address.
By appending a period to the hostname, the hostname should only resolve
to what we want it to resolve to. Hopefully this doesn't break different bots.

New functions runtest_inner() and cleanup_test_droppings() in

run immediately after test_file. At least 8 buildbot
boxes passed since the underlying problem got fixed,
and they all failed before the fix, so there's no point
to this anymore.
test clean up after itself appears to fix the test failures
when test_optparse follows test_file.
test_main(): Get rid of TESTFN no matter what. That's
also enough to fix the mystery failures. Doesn't hurt
to fix them twice :-)
Since test_file is implicated in mysterious test failures
when followed by test_optparse, if I had any brains I'd
look at the checkin that last changed test_file ;-)
the char buffer was requested. Now it actually returns the char buffer if
available or raises a TypeError if it isn't (as is raised for the other buffer
types if they are not present but requested).
Not a backport candidate since it does change semantics of the buffer object
(although it could be argued this is enough of a bug to bother backporting).
Give a consistent behavior for comparison and hashing of method objects

The hash was already asking for the hash of 'self'.

the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).
Found them using::
find . -name '*.py' | while read i ; do grep 'def[^(]*( ' $i /dev/null ; done
find . -name '*.py' | while read i ; do grep ' ):' $i /dev/null ; done
(I was doing this all over my own code anyway, because I'd been using spaces in
all defs, so I thought I'd make a run on the Python code as well. If you need
to do such fixes in your own code, you can use xx-rename or parenregu.el within
emacs.)
string_reverse(): Simplify.
assertRaises(): Raise TestFailed on failure.
test_unpack_from(), test_pack_into(), test_pack_into_fn(): never
use `assert` to test for an expected result (it doesn't test anything
when Python is run with -O).
Move the long-winded, multiply-nested -R support out
of runtest() and into some module-level helper functions.
This makes runtest() and the -R code easier to follow.
That in turn allowed seeing some opportunities for code
simplification, and made it obvious that reglog.txt
never got closed.

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like

* pack_to -> pack_into
* recv_buf -> recv_into

- Converted some ints into the appropriate -- I hope -- ssize_t and size_t.
the output required more than one line. "Small" dicts got
displayed in seemingly random order (the hash-induced order
produced by dict.__repr__). None of this was documented.
Now pprint functions always sort dicts by key, and the docs
promise it.
This was proposed and agreed to during the PyCon 2006 core

The `warnings` module needs an advertised way to save/restore
its internal filter list.
Renames functional extension module to _functools and adds a Python
functools module so that utility functions like update_wrapper can be

Remove various dependencies on dictionary order in the standard library
tests, and one (clearly an oversight, potentially critical) in the
standard library itself - base64.py.
Remaining open issues:
* test_extcall is an output test, messy to make robust
* tarfile.py has a potential bug here, but I'm not familiar
enough with this code. Filed in as SF bug #1496501.
* urllib2.HTTPPasswordMgr() returns a random result if there is more
than one matching root path. I'm asking python-dev for
clarification...
failures on Windows buildbots, but it's hard to know how since the regrtest
failure output is useless here, and it never fails when a buildbot slave runs
test_tarfile the second time in verbose mode.
The new split functions use a preallocated list. Added tests which exceed
the preallocation size, to exercise list appends/resizes.
Also added more edge case tests.
* Added socket.recv_buf() and socket.recvfrom_buf() methods, that use the buffer
protocol (send and sendto already did).
* Added struct.pack_to(), that is the corresponding buffer compatible method to
unpack_from().
* Fixed minor typos in arraymodule.
the Need For Speed sprint coding. Includes commented out overflow tests
which will be uncommented once the code is fixed.
This test will break the 8-bit string tests because
"".replace("", "A") == "" when it should == "A"
We have a fix for it, which should be added tomorrow.
In rare cases of strings specifying true values near sys.maxint,
and oddball bases (not decimal or a power of 2), int(string, base)
could deliver insane answers. This repairs all such problems, and
also speeds string->int significantly. On my box, here are %
speedups for decimal strings of various lengths:
length speedup
------ -------
1 12.4%
2 15.7%
3 20.6%
4 28.1%
5 33.2%
6 37.5%
7 41.9%
8 46.3%
9 51.2%
10 19.5%
11 19.9%
12 23.9%
13 23.7%
14 23.3%
15 24.9%
16 25.3%
17 28.3%
18 27.9%
19 35.7%
Note that the difference between 9 and 10 is the difference between
short and long Python ints on a 32-bit box. The patch doesn't
actually do anything to speed conversion to long: the speedup is
due to detecting "unsigned long" overflow more quickly.
This is a bugfix candidate, but it's a non-trivial patch and it
would be painful to separate the "bug fix" from the "speed up" parts.

The Windows buildbot slaves shouldn't swap themselves to death

temp directory left behind from a previous failing run.
Windows buildbot owners may need to remove that directory

Patch #1464708 from William McVey: fixed handling of nested comments in mail
addresses. E.g.

Fixes for both rfc822.py and email package. This patch needs to be back

Printing to stdout, doesn't mean the data was actually written.
It depends on the buffering, so we need to flush. This will hopefully
really fix the buildbots getting killed due to no output on the slow bots.
- Warn-raise ImportWarning when importing would have picked up a directory
as package, if only it'd had an __init__.py. This swaps two tests (for
case-ness and __init__-ness), but case-test is not really more expensive,
and it's not in a speed-critical section.
- Test for the new warning by importing a common non-package directory on
sys.path: site-packages
- In regrtest.py, silence warnings generated by the build-environment
because Modules/ (which is added to sys.path for Setup-created modules)
has 'zlib' and '_ctypes' directories without __init__.py's.

something to play with in 2.5 alpha 2, and hopefully get more people to
write these tests.

not a test failure -- you have to pay attention to the

It's likely that more renaming in test_with.py would be desirable.
The new char-array used in ioctl calls wasn't explicitly NUL-terminated;
quite probably the cause for the test_pty failures on Solaris that we
circumvented earlier. (I wasn't able to reproduce it with this patch, but it
has been somewhat elusive to start with.)
terminology in the alpha 1 documentation.
- "context manager" reverts to its alpha 1 definition
- the term "context specifier" goes away entirely
- contextlib.GeneratorContextManager is renamed GeneratorContext
There are still a number of changes relative to alpha 1:
- the expression in the with statement is explicitly called the
"context expression" in the language reference
- the terms 'with statement context', 'context object' or 'with
statement context' are used in several places instead of a bare
'context'. The aim of this is to avoid ambiguity in relation to the
runtime context set up when the block is executed, and the context
objects that already exist in various application domains (such as
decimal.Context)
- contextlib.contextmanager is renamed to contextfactory
This best reflects the nature of the function resulting from the
use of that decorator
- decimal.ContextManager is renamed to WithStatementContext
Simple dropping the 'Manager' part wasn't possible due to the
fact that decimal.Context already exists and means something
different. WithStatementContext is ugly but workable.
A technically unrelated change snuck into this commit:
contextlib.closing now avoids the overhead of creating a

context manager directly.
the 2005 Summer of Code).
The revision adds a number of new mailbox classes that support adding
and removing messages; these classes also support mailbox locking and
default to using email.Message instead of rfc822.Message.
The old mailbox classes are largely left alone for backward compatibility.
The exception is the Maildir class, which was present in the old module
and now inherits from the new classes. The Maildir class's interface
is pretty simple, though, so I think it'll be compatible with existing
code.
(The change to the NEWS file also adds a missing word to a different
news item, which unfortunately required rewrapping the line.)
compatibility classes in the new mailbox.py that I'll be committing in
a few minutes.
One change has been made: the tests use len(mbox) instead of len(mbox.boxes).
The 'boxes' attribute was never documented and contains some internal state
that seems unlikely to have been useful.
Python 2.4 changed ntpath.abspath to do an import
inside the function. As a result, due to Python's
import lock, anything calling abspath on Windows
(directly, or indirectly like tempfile.TemporaryFile)
hung when it was called from a thread spawned as a
side effect of importing a module.
This is a depressingly frequent problem, and
deserves a more general fix. I'm settling for
a micro-fix here because this specific one accounts
for a report of Zope Corp's ZEO hanging on Windows,
and it was an odd way to change abspath to begin
with (ntpath needs a different implementation
depending on whether we're actually running on
Windows, and the _obvious_ way to arrange for that
is not to bury a possibly-failing import _inside_
the function).
Note that if/when other micro-fixes of this kind
get made, the new Lib/test/threaded_import_hangers.py
is a convenient place to add tests for them.
