There are two places of documentation that still mention __context__:
Doc/lib/libstdtypes.tex -- I wasn't quite sure how to rewrite that without
spending a whole lot of time thinking about it; and whatsnew, which Andrew
usually likes to change himself.
Patch #1464708 from William McVey: fixed handling of nested comments in mail
addresses. E.g.
"Foo ((Foo Bar)) <foo@example.com>"
Fixes for both rfc822.py and email package. This patch needs to be back
ported to Python 2.3 for email 2.5.
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.
tuples. Lots to be added, still, but this will give big-memory people
something to play with in 2.5 alpha 2, and hopefully get more people to
write these tests.
uses of it in test_with.py. As a result, test_with has been skipped
(due to failing imports) on all buildbot boxes since. Alas, that's
not a test failure -- you have to pay attention to the
1 skip unexpected on PLATFORM:
test_with
kinds of output at the ends of test runs to notice that this got
broken.
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
generator, since it's trivial to implement that particular
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.
bottom of the file. Restored that, and added a comment
explaining why this is necessary. Hint: on my box, and
yours, it's not :-(
Also added an __all__ list.
and provide a substitute if the import fails, because pyclbr sees the
class definition. Changed to ignore such cases' base classes and methods,
since they will not match.
to share common PEP 302 support code, as described here:
http://mail.python.org/pipermail/python-dev/2006-April/063724.html
pydoc now supports PEP 302 importers, by way of utility functions in
pkgutil, such as 'walk_packages()'. It will properly document
modules that are in zip files, and is backward compatible to Python
2.3 (setuptools installs for Python <2.5 will bundle it so pydoc
doesn't break when used with eggs.)
What has not changed is that pydoc command line options do not support
zip paths or other importer paths, and the webserver index does not
support sys.meta_path. Those are probably okay as limitations.
Tasks remaining: write docs and Misc/NEWS for pkgutil/pydoc changes,
and update setuptools to use pkgutil wherever possible, then add it
to the stdlib.
much convolution <0.5 wink>. Simplified to the point that it works,
and test_threading_local no longer reports leaks under -R. Thanks
to Thomas Wouters for initial analysis.
to share common PEP 302 support code, as described here:
http://mail.python.org/pipermail/python-dev/2006-April/063724.html
This revision strips all the PEP 302 emulation code from runpy,
replacing it with published API classes and functions in pkgutil,
mostly using setuptools' implementation of common functionality,
but adding features from runpy, and doing some refactoring to make
the layer pydoc needs easier to implement on top of this.
One step down, four to go, although step #4 (adding C versions of
the new APIs to 'imp') may not be able to make it in time for
alpha 2. We'll see how that goes.
configure time. The current check is too strict and doesn't allow building
extensions that can only run on newer versions of the OS than the version
python was build for, that is python build for 10.3 or later and an extension
for 10.4. This patch relaxes this check.
This turned out to be a reimplementation of patch 1193190.
/path/to/uninstalled/python setup.py build_ext

the above command did not look for pyconfig.h, but the
bug is really in the look-up code: expecting to find it
in os.curdir is a rather fragile idea.
'python.org' when deciding what server to use for the timeout tests; getting
tired of seeing the test fail on all my boxes ;P This'll still allow the
test to fail for hosts in the XS4ALL network that don't have an 'xs4all'
hostname, so maybe it should use a fallback scheme instead.
exceptions that can't be raised any further, because (for instance) they
occur in __del__ methods. The coroutine tests in test_generators was
triggering this leak. Remove the leakers' testcase, and add a simpler
testcase that explicitly tests this leak to test_generators.
test_generators now no longer leaks at all, on my machine. This fix may also
solve other leaks, but my full refleakhunting run is still busy, so who
knows?
not be tracked by GC. This fixes 254 of test_generators' refleaks on my
machine, but I'm sure something else will make them come back :>
Not adding a separate test for this kind of cycle, since the existing
fib/m235 already test them in more extensive ways than any 'minimal' test
has been able to manage.
examples no longer require any explicit closing to avoid
leaking.
That the tee-based examples still do is (I think) still a
mystery. Part of the mystery is that gc.garbage remains
empty: if it were the case that some generator in a trash
cycle said it needed finalization, suppressing collection
of that cycle, that generator _would_ show up in gc.garbage.
So this is acting more like, e.g., some tp_traverse slot
isn't visiting all the pointers it should (in which case
the skipped pointer(s) would act like an external root,
silently suppressing collection of everything reachable
from it(them)).
problems: first, PyGen_NeedsFinalizing() had an off-by-one bug that
prevented it from ever saying a generator didn't need finalizing, and
second, frame objects cleared themselves in a way that caused their
owning generator to think they were still executable, causing a double
deallocation of objects on the value stack if there was still a loop
on the block stack. This revision also removes some unnecessary
close() operations from test_generators that are now appropriately
handled by the cycle collector.
an incremental encoder that must retain part of the data between calls
to the encode() method.
Fix the incremental encoder and decoder for the IDNA encoding.
This closes SF patch #1453235.
The test case came from test_generators, not test_itertools.
Ensure there's no cyclic garbage we are counting.
This is weird because it leaks, then reaches a limit:

instance as part of cleanup(). Also cleanup() before running the
first test repetition (the test was run once before we get into
the -R branch).
This may be causing the debian sparc buildbot to fail.
Print a little message to let the user ^w buildbot know it's still thinking.
We may want to adjust the time period which is currently 5 minutes.
Will backport.
prepends the exception's module name to non-builtin exceptions, like
the interpreter itself does.

discussion on python-dev).
bsddb.*open() methods cachesize parameter wouldn't work (raised an
internal bsddb.db exception when it was given). The set_cachesize
call needed to be moved from the DB object to the DBEnv since the env
was introduced to allow for threading.

Using None for a filename with the 'n' flag when calling bsddb.btopen

use the 'c' flag in the first place.
"x86 OpenBSD trunk" buildbot due to changing Python so that
Python-exposed addresses are always non-negative.
test_int_pointer_arg(): This line failed now whenever the
box happened to assign an address to `ci` "with the sign
bit set":
self.failUnlessEqual(addressof(ci), func(byref(ci)))
The problem is that the ctypes addressof() inherited "all
addresses are non-negative now" from changes to
PyLong_FromVoidPtr(), but byref() did not inherit that
change and can still return a negative int.
I don't know whether, or what, the ctypes implementation wants
to do about that (possibly nothing), but in the meantime
the test fails frequently.
So, introduced a Python positive_address() function in
the test module, that takes a purported machine address and,
if negative, converts it to a non-negative value "with the
same bits". This should leave the test passing under all
versions of Python.
Belated thanks to Armin Rigo for teaching me the sick trick ;-)
for determining the # of bits in a machine pointer via abuse
of the struct module.
tests. Alas, because only the "x86 OpenBSD trunk" buildbot fails
these tests, and test_descr stops after the first failure, there's
no sane way for me to fix these short of fixing one and then
waiting for the buildbot to reveal the next one.
to that id() can now return a Python long on a 32-bit box that allocates
addresses "with the sign bit set".
test_set.py test_subclass_with_custom_hash(): it's never been portably
legal for a __hash__() method to return id(self), but on 32-bit boxes
that never caused a problem before it became possible for id() to
return a Python long. Changed __hash__ here to return a Python int
regardless of platform.
test_descr.py specials():
vereq(hash(c1), id(c1))
has never been a correct test -- just removed it (hash() is always
a Python int; id() may be a Python long).
