SF bug #574132: Major GC related performance regression
"The regression" is actually due to that 2.2.1 had a bug that prevented
the regression (which isn't a regression at all) from showing up. "The
regression" is actually a glitch in cyclic gc that's been there forever.
As the generation being collected is analyzed, objects that can't be
collected (because, e.g., we find they're externally referenced, or
are in an unreachable cycle but have a __del__ method) are moved out
of the list of candidates. A tricksy scheme uses negative values of
gc_refs to mark such objects as being moved. However, the exact
negative value set at the start may become "more negative" over time
for objects not in the generation being collected, and the scheme was
checking for an exact match on the negative value originally assigned.
As a result, objects in generations older than the one being collected
could get scanned too, and yanked back into a younger generation. Doing
so doesn't lead to an error, but doesn't do any good, and can burn an
unbounded amount of time doing useless work.
A test case is simple (thanks to Kevin Jacobs for finding it!):
x = []
for i in xrange(200000):
x.append((1,))
Without the patch, this ends up scanning all of x on every gen0 collection,
scans all of x twice on every gen1 collection, and x gets yanked back into
gen1 on every gen0 collection. With the patch, once x gets to gen2, it's
never scanned again until another gen2 collection, and stays in gen2.
Bugfix candidate, although the code has changed enough that I think I'll
need to port it by hand. 2.2.1 also has a different bug that causes
bound method objects not to get tracked at all (so the test case doesn't
burn absurd amounts of time in 2.2.1, but *should* <wink>).

NOTE: about the counting of long-lived objects.
|
|
|
|
|
|
|
|
To limit the cost of garbage collection, there are two strategies;
|
|
|
|
- make each collection faster, e.g. by scanning fewer objects
|
|
|
|
- do less collections
|
|
|
|
This heuristic is about the latter strategy.
|
|
|
|
|
|
|
|
In addition to the various configurable thresholds, we only trigger a
|
|
|
|
full collection if the ratio
|
2010-05-09 23:52:27 +08:00
|
|
|
long_lived_pending / long_lived_total
|
2009-01-10 06:27:08 +08:00
|
|
|
is above a given value (hardwired to 25%).
|
|
|
|
|
|
|
|
The reason is that, while "non-full" collections (i.e., collections of
|
|
|
|
the young and middle generations) will always examine roughly the same
|
|
|
|
number of objects -- determined by the aforementioned thresholds --,
|
|
|
|
the cost of a full collection is proportional to the total number of
|
|
|
|
long-lived objects, which is virtually unbounded.
|
|
|
|
|
|
|
|
Indeed, it has been remarked that doing a full collection every
|
|
|
|
<constant number> of object creations entails a dramatic performance
|
|
|
|
degradation in workloads which consist in creating and storing lots of
|
|
|
|
long-lived objects (e.g. building a large list of GC-tracked objects would
|
|
|
|
show quadratic performance, instead of linear as expected: see issue #4074).
|
|
|
|
|
|
|
|
Using the above ratio, instead, yields amortized linear performance in
|
|
|
|
the total number of objects (the effect of which can be summarized
|
|
|
|
thusly: "each full garbage collection is more and more costly as the
|
|
|
|
number of objects grows, but we do fewer and fewer of them").
|
|
|
|
|
|
|
|
This heuristic was suggested by Martin von Löwis on python-dev in
|
|
|
|
June 2008. His original analysis and proposal can be found at:

|
NOTE: about untracking of mutable objects.
|
|
|
|
|
|
|
|
Certain types of container cannot participate in a reference cycle, and
|
|
|
|
so do not need to be tracked by the garbage collector. Untracking these
|
|
|
|
objects reduces the cost of garbage collections. However, determining
|
|
|
|
which objects may be untracked is not free, and the costs must be
|
|
|
|
weighed against the benefits for garbage collection.
|
|
|
|
|
|
|
|
There are two possible strategies for when to untrack a container:
|
|
|
|
|
|
|
|
i) When the container is created.
|
|
|
|
ii) When the container is examined by the garbage collector.
|
|
|
|
|
|
|
|
Tuples containing only immutable objects (integers, strings etc, and
|
|
|
|
recursively, tuples of immutable objects) do not need to be tracked.
|
|
|
|
The interpreter creates a large number of tuples, many of which will
|
|
|
|
not survive until garbage collection. It is therefore not worthwhile
|
|
|
|
to untrack eligible tuples at creation time.
|
|
|
|
|
|
|
|
Instead, all tuples except the empty tuple are tracked when created.
|
|
|
|
During garbage collection it is determined whether any surviving tuples
|
|
|
|
can be untracked. A tuple can be untracked if all of its contents are
|
|
|
|
already not tracked. Tuples are examined for untracking in all garbage
|
|
|
|
collection cycles. It may take more than one cycle to untrack a tuple.
|
|
|
|
|
|
|
|
Dictionaries containing only immutable objects also do not need to be
|
|
|
|
tracked. Dictionaries are untracked when created. If a tracked item is
|
|
|
|
inserted into a dictionary (either as a key or value), the dictionary
|
|
|
|
becomes tracked. During a full garbage collection (all generations),
|
|
|
|
the collector will untrack any dictionaries whose contents are not
|
|
|
|
tracked.
|
|
|
|
|
|
|
|
The module provides the python function is_tracked(obj), which returns
|
|
|
|
the CURRENT tracking status of the object. Subsequent garbage
|
|
|
|
collections may change the tracking status of the object.
|
|
|
|
|
|
|
|
Untracking of certain containers was introduced in issue #4688, and
|
|
|
|
the algorithm was refined in response to issue #14775.

SF bug #1473760 TempFile can hang on Windows.
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.

Add Gregory K. Johnson's revised version of mailbox.py (funded by
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.)

Move the PEP 343 documentation and implementation closer to the
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.

Define MAXPATHLEN to be at least PATH_MAX, if that's defined. Python uses
MAXPATHLEN-sized buffers for various output-buffers (like to realpath()),
and that's correct on BSD platforms, but not Linux (which uses PATH_MAX, and
does not define MAXPATHLEN.) Cursory googling suggests Linux is following a
newer standard than BSD, but in cases like this, who knows. Using the
greater of PATH_MAX and 1024 as a fallback for MAXPATHLEN seems to be the
most portable solution.

Rev 45706 renamed stuff in contextlib.py, but didn't rename
uses of it in test_with.py. As a result, test_with has been skipped

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.

After the patch (45590) to add extra debug stats to the gc module, Python
was crashing on OpenBSD due to:

as package, if only it'd had an __init__.py. This swaps two tests (for

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

because Modules/ (which is added to sys.path for Setup-created modules)

Teach PyString_FromFormat, PyErr_Format, and PyString_FromFormatV
about "%u", "%lu" and "%zu" formats.
Since PyString_FromFormat and PyErr_Format have exactly the same rules
(both inherited from PyString_FromFormatV), it would be good if someone
with more LaTeX Fu changed one of them to just point to the other.
Their docs were way out of synch before this patch, and I just did a
mass copy+paste to repair that.
Not a backport candidate (this is a new feature).

Rework the build system for osx applications:
* Don't use xcodebuild for building PythonLauncher, but use a normal unix
makefile. This makes it a lot easier to use the same build flags as for the
rest of python (e.g. make a universal version of python launcher)
* Convert the mac makefile-s to makefile.in-s and use configure to set makefile
variables instead of forwarding them as command-line arguments
* Add a C version of pythonw, that we you can use '#!/usr/local/bin/pythonw'
* Build IDLE.app using bundlebuilder instead of BuildApplet, that will allow
easier modification of the bundle contents later on.

Bug #1334662 / patch #1335972: int(string, base) wrong answers.
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.

for more on the algorithm, see:

if you get weird results, you can disable the new algoritm by undefining

Added a slew of test for string replace, based various corner cases from
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.

Heavily fiddled variant of patch #1442927: PyLong_FromString optimization.
``long(str, base)`` is now up to 6x faster for non-power-of-2 bases. The
largest speedup is for inputs with about 1000 decimal digits. Conversion
from non-power-of-2 bases remains quadratic-time in the number of input
digits (it was and remains linear-time for bases 2, 4, 8, 16 and 32).
Speedups at various lengths for decimal inputs, comparing 2.4.3 with
current trunk. Note that it's actually a bit slower for 1-digit strings:

Fixed problem identified by Georg. The special-case in-place code for replace
made a copy of the string using PyString_FromStringAndSize(s, n) and modify
the copied string in-place. However, 1 (and 0) character strings are shared
from a cache. This cause "A".replace("A", "a") to change the cached version
of "A" -- used by everyone.
Now may the copy with NULL as the string and do the memcpy manually. I've
added regression tests to check if this happens in the future. Perhaps
there should be a PyString_Copy for this case?

Changes to string.split/rsplit on whitespace to preallocate space in the
results list.
Originally it allocated 0 items and used the list growth during append. Now
it preallocates 12 items so the first few appends don't need list reallocs.
("Here are some words ."*2).split(None, 1) is 7% faster
("Here are some words ."*2).split() is is 15% faster
(Your milage may vary, see dealership for details.)
File parsing like this
for line in f:
count += len(line.split())
is also about 15% faster. There is a slowdown of about 3% for large
strings because of the additional overhead of checking if the append is
to a preallocated region of the list or not. This will be the rare case.
It could be improved with special case code but we decided it was not
useful enough.
There is a cost of 12*sizeof(PyObject *) bytes per list. For the normal
case of file parsing this is not a problem because of the lists have
a short lifetime. We have not come up with cases where this is a problem
in real life.
I chose 12 because human text averages about 11 words per line in books,
one of my data sets averages 6.2 words with a final peak at 11 words per
line, and I work with a tab delimited data set with 8 tabs per line (or
9 words per line). 12 encompasses all of these.
Also changed the last rstrip code to append then reverse, rather than
doing insert(0). The strip() and rstrip() times are now comparable.

substring split now uses /F's fast string matching algorithm.
(If compiled without FAST search support, changed the pre-memcmp test
to check the last character as well as the first. This gave a 25%
speedup for my test case.)
Rewrote the split algorithms so they stop when maxsplit gets to 0.
Previously they did a string match first then checked if the maxsplit
was reached. The new way prevents a needless string search.

Patch 1145039.
set_exc_info(), reset_exc_info(): By exploiting the
likely (who knows?) invariant that when an exception's
`type` is NULL, its `value` and `traceback` are also NULL,
save some cycles in heavily-executed code.
This is a "a kronar saved is a kronar earned" patch: the
speedup isn't reliably measurable, but it obviously does
reduce the operation count in the normal (no exception
raised) path through PyEval_EvalFrameEx().
The tim-exc_sanity branch tries to push this harder, but
is still blowing up (at least in part due to pre-existing
subtle bugs that appear to have no other visible
consequences!).
Not a bugfix candidate.

gc_refs values.
|
|
|
|
|
|
|
|
Between collections, every gc'ed object has one of two gc_refs values:
|
|
|
|
|
|
|
|
GC_UNTRACKED
|
|
|
|
The initial state; objects returned by PyObject_GC_Malloc are in this
|
|
|
|
state. The object doesn't live in any generation list, and its
|
|
|
|
tp_traverse slot must not be called.
|
|
|
|
|
|
|
|
GC_REACHABLE
|
|
|
|
The object lives in some generation list, and its tp_traverse is safe to
|
|
|
|
call. An object transitions to GC_REACHABLE when PyObject_GC_Track
|
|
|
|
is called.
|
|
|
|
|
|
|
|
During a collection, gc_refs can temporarily take on other states:
|
|
|
|
|
|
|
|
>= 0
|
|
|
|
At the start of a collection, update_refs() copies the true refcount
|
|
|
|
to gc_refs, for each object in the generation being collected.
|
|
|
|
subtract_refs() then adjusts gc_refs so that it equals the number of
|
|
|
|
times an object is referenced directly from outside the generation
|
|
|
|
being collected.
|
2002-11-10 03:54:06 +08:00
|
|
|
gc_refs remains >= 0 throughout these steps.
|
2002-07-03 02:12:35 +08:00
|
|
|
|
|
|
|
GC_TENTATIVELY_UNREACHABLE
|
|
|
|
move_unreachable() then moves objects not reachable (whether directly or
|
|
|
|
indirectly) from outside the generation into an "unreachable" set.
|
|
|
|
Objects that are found to be reachable have gc_refs set to GC_REACHABLE
|
|
|
|
again. Objects that are found to be unreachable have gc_refs set to
|
|
|
|
GC_TENTATIVELY_UNREACHABLE. It's "tentatively" because the pass doing
|
|
|
|
this can't be sure until it ends, and GC_TENTATIVELY_UNREACHABLE may
|
|
|
|
transition back to GC_REACHABLE.
|
|
|
|
|
|
|
|
Only objects with GC_TENTATIVELY_UNREACHABLE still set are candidates
|
|
|
|
for collection. If it's decided not to collect such an object (e.g.,
|
|
|
|
it has a __del__ method), its gc_refs is restored to GC_REACHABLE again.

OK, I couldn't stand it <0.5 wink>: removed all uncertainty about what's
in gc_refs, even at the cost of putting back a test+branch in
visit_decref.
The good news: since gc_refs became utterly tame then, it became
clear that another special value could be useful. The move_roots() and
move_root_reachable() passes have now been replaced by a single
move_unreachable() pass. Besides saving a pass over the generation, this
has a better effect: most of the time everything turns out to be
reachable, so we were breaking the generation list apart and moving it
into into the reachable list, one element at a time. Now the reachable
stuff stays in the generation list, and the unreachable stuff is moved
instead. This isn't quite as good as it sounds, since sometimes we
guess wrongly that a thing is unreachable, and have to move it back again.
Still, overall, it yields a significant (but not dramatic) boost in
collection speed.

SF bug #574132: Major GC related performance regression
"The regression" is actually due to that 2.2.1 had a bug that prevented
the regression (which isn't a regression at all) from showing up. "The
regression" is actually a glitch in cyclic gc that's been there forever.
As the generation being collected is analyzed, objects that can't be
collected (because, e.g., we find they're externally referenced, or
are in an unreachable cycle but have a __del__ method) are moved out
of the list of candidates. A tricksy scheme uses negative values of
gc_refs to mark such objects as being moved. However, the exact
negative value set at the start may become "more negative" over time
for objects not in the generation being collected, and the scheme was
checking for an exact match on the negative value originally assigned.
As a result, objects in generations older than the one being collected
could get scanned too, and yanked back into a younger generation. Doing
so doesn't lead to an error, but doesn't do any good, and can burn an
unbounded amount of time doing useless work.
A test case is simple (thanks to Kevin Jacobs for finding it!):
x = []
for i in xrange(200000):
x.append((1,))
Without the patch, this ends up scanning all of x on every gen0 collection,
scans all of x twice on every gen1 collection, and x gets yanked back into
gen1 on every gen0 collection. With the patch, once x gets to gen2, it's
never scanned again until another gen2 collection, and stays in gen2.
Bugfix candidate, although the code has changed enough that I think I'll
need to port it by hand. 2.2.1 also has a different bug that causes
bound method objects not to get tracked at all (so the test case doesn't
burn absurd amounts of time in 2.2.1, but *should* <wink>).

SF bug #574132: Major GC related performance regression
"The regression" is actually due to that 2.2.1 had a bug that prevented
the regression (which isn't a regression at all) from showing up. "The
regression" is actually a glitch in cyclic gc that's been there forever.
As the generation being collected is analyzed, objects that can't be
collected (because, e.g., we find they're externally referenced, or
are in an unreachable cycle but have a __del__ method) are moved out
of the list of candidates. A tricksy scheme uses negative values of
gc_refs to mark such objects as being moved. However, the exact
negative value set at the start may become "more negative" over time
for objects not in the generation being collected, and the scheme was
checking for an exact match on the negative value originally assigned.
As a result, objects in generations older than the one being collected
could get scanned too, and yanked back into a younger generation. Doing
so doesn't lead to an error, but doesn't do any good, and can burn an
unbounded amount of time doing useless work.
A test case is simple (thanks to Kevin Jacobs for finding it!):
x = []
for i in xrange(200000):
x.append((1,))
Without the patch, this ends up scanning all of x on every gen0 collection,
scans all of x twice on every gen1 collection, and x gets yanked back into
gen1 on every gen0 collection. With the patch, once x gets to gen2, it's
never scanned again until another gen2 collection, and stays in gen2.
Bugfix candidate, although the code has changed enough that I think I'll
need to port it by hand. 2.2.1 also has a different bug that causes
bound method objects not to get tracked at all (so the test case doesn't
burn absurd amounts of time in 2.2.1, but *should* <wink>).

/* Move objects that are reachable from finalizers, from the unreachable set

Reworked has_finalizer() to use the new _PyObject_Lookup() instead
of PyObject_HasAttr(); the former promises never to execute
arbitrary Python code. Undid many of the changes recently made to
worm around the worst consequences of that PyObject_HasAttr() could
execute arbitrary Python code.
Compatibility is hard to discuss, because the dangerous cases are
so perverse, and much of this appears to rely on implementation
accidents.
To start with, using hasattr() to check for __del__ wasn't only
dangerous, in some cases it was wrong: if an instance of an old-
style class didn't have "__del__" in its instance dict or in any
base class dict, but a getattr hook said __del__ existed, then
hasattr() said "yes, this object has a __del__". But
instance_dealloc() ignores the possibility of getattr hooks when
looking for a __del__, so while object.__del__ succeeds, no
__del__ method is called when the object is deleted. gc was
therefore incorrect in believing that the object had a finalizer.
The new method doesn't suffer that problem (like instance_dealloc(),
_PyObject_Lookup() doesn't believe __del__ exists in that case), but
does suffer a somewhat opposite-- and even more obscure --oddity:
if an instance of an old-style class doesn't have "__del__" in its
instance dict, and a base class does have "__del__" in its dict,
and the first base class with a "__del__" associates it with a
descriptor (an object with a __get__ method), *and* if that
descriptor raises an exception when __get__ is called, then
(a) the current method believes the instance does have a __del__,
but (b) hasattr() does not believe the instance has a __del__.
While these disagree, I believe the new method is "more correct":
because the descriptor *will* be called when the object is
destructed, it can execute arbitrary Python code at the time the
object is destructed, and that's really what gc means by "has a
finalizer": not specifically a __del__ method, but more generally
the possibility of executing arbitrary Python code at object
destruction time. Code in a descriptor's __get__() executed at
destruction time can be just as problematic as code in a
__del__() executed then.
So I believe the new method is better on all counts.
Bugfix candidate, but it's unclear to me how all this differs in
the 2.2 branch (e.g., new-style and old-style classes already
took different gc paths in 2.3 before this last round of patches,
but don't in the 2.2 branch).

OK, I couldn't stand it <0.5 wink>: removed all uncertainty about what's
in gc_refs, even at the cost of putting back a test+branch in
visit_decref.
The good news: since gc_refs became utterly tame then, it became
clear that another special value could be useful. The move_roots() and
move_root_reachable() passes have now been replaced by a single
move_unreachable() pass. Besides saving a pass over the generation, this
has a better effect: most of the time everything turns out to be
reachable, so we were breaking the generation list apart and moving it
into into the reachable list, one element at a time. Now the reachable
stuff stays in the generation list, and the unreachable stuff is moved
instead. This isn't quite as good as it sounds, since sometimes we
guess wrongly that a thing is unreachable, and have to move it back again.
Still, overall, it yields a significant (but not dramatic) boost in
collection speed.

Reworked has_finalizer() to use the new _PyObject_Lookup() instead
of PyObject_HasAttr(); the former promises never to execute
arbitrary Python code. Undid many of the changes recently made to
worm around the worst consequences of that PyObject_HasAttr() could
execute arbitrary Python code.
Compatibility is hard to discuss, because the dangerous cases are
so perverse, and much of this appears to rely on implementation
accidents.
To start with, using hasattr() to check for __del__ wasn't only
dangerous, in some cases it was wrong: if an instance of an old-
style class didn't have "__del__" in its instance dict or in any
base class dict, but a getattr hook said __del__ existed, then
hasattr() said "yes, this object has a __del__". But
instance_dealloc() ignores the possibility of getattr hooks when
looking for a __del__, so while object.__del__ succeeds, no
__del__ method is called when the object is deleted. gc was
therefore incorrect in believing that the object had a finalizer.
The new method doesn't suffer that problem (like instance_dealloc(),
_PyObject_Lookup() doesn't believe __del__ exists in that case), but
does suffer a somewhat opposite-- and even more obscure --oddity:
if an instance of an old-style class doesn't have "__del__" in its

* tricky business as the lists can be changing and we don't know which
|
OK, I couldn't stand it <0.5 wink>: removed all uncertainty about what's
in gc_refs, even at the cost of putting back a test+branch in
visit_decref.
The good news: since gc_refs became utterly tame then, it became
clear that another special value could be useful. The move_roots() and
move_root_reachable() passes have now been replaced by a single
move_unreachable() pass. Besides saving a pass over the generation, this
has a better effect: most of the time everything turns out to be
reachable, so we were breaking the generation list apart and moving it
into into the reachable list, one element at a time. Now the reachable
stuff stays in the generation list, and the unreachable stuff is moved
instead. This isn't quite as good as it sounds, since sometimes we
guess wrongly that a thing is unreachable, and have to move it back again.
Still, overall, it yields a significant (but not dramatic) boost in
collection speed.

x**2 should about equal x*x (including for a float x such that the result is
inf) but didn't; added a test to test_float to verify that, and ignored the
ERANGE value for errno in the pow operation to make the new test pass (with
help from Marilyn Davis at the Google Python Sprint -- thanks!).

Bug fixes large and small for tokenize.
Small: Always generate a NL or NEWLINE token following
a COMMENT token. The old code did not generate an NL token if
the comment was on a line by itself.
Large: The output of untokenize() will now match the
input exactly if it is passed the full token sequence. The
old, crufty output is still generated if a limited input
sequence is provided, where limited means that it does not
include position information for tokens.
Remaining bug: There is no CONTINUATION token (\) so there is no way
for untokenize() to handle such code.
Also, expanded the number of doctests in hopes of eventually removing
the old-style tests that compare against a golden file.
Bug fix candidate for Python 2.5.1. (Sigh.)

Reverting the patch that tried to fix the issue whereby x**2 raises
OverflowError while x*x succeeds and produces infinity; apparently
these inconsistencies cannot be fixed across ``all'' platforms and
there's a widespread feeling that therefore ``every'' platform
should keep suffering forevermore. Ah well.

"Conceptual" merge of rev 51711 from the 2.5 branch.
i_divmod(): As discussed on Python-Dev, changed the overflow
checking to live happily with recent gcc optimizations that
assume signed integer arithmetic never overflows.
This differs from the corresponding change on the 2.5 and 2.4
branches, using a less obscure approach, but one that /may/
tickle platform idiocies in their definitions of LONG_MIN.
The 2.4 + 2.5 change avoided introducing a dependence on
LONG_MIN, at the cost of substantially goofier code.

Bug #1520864 (again): unpacking singleton tuples in list comprehensions and
generator expressions (x for x, in ... ) works again.
Sigh, I only fixed for loops the first time, not list comps and genexprs too.
I couldn't find any more unpacking cases where there is a similar bug lurking.
This code should be refactored to eliminate the duplication. I'm sure
the listcomp/genexpr code can be refactored. I'm not sure if the for loop
can re-use any of the same code though.

Building with HP's cc on HP-UX turned up a couple of problems.
_PyGILState_NoteThreadState was declared as static inconsistently.
Make it static as it's not necessary outside of this module.
Some tests failed because errno was reset to 0. (I think the tests
that failed were at least: test_fcntl and test_mailbox).
Ensure that errno doesn't change after a call to Py_END_ALLOW_THREADS.

Fix %zd string formatting on Mac OS X so it prints negative numbers.
In addition to testing positive numbers, verify negative numbers work in configure.
In order to avoid compiler warnings on OS X 10.4, also change the order of the check
for the format character to use (PY_FORMAT_SIZE_T) in the sprintf format
for Py_ssize_t. This patch changes PY_FORMAT_SIZE_T from "" to "l" if it wasn't
defined at configure time. Need to verify the buildbot results.

Forward-port of r52136,52138: a review of overflow-detecting code.
* unified the way intobject, longobject and mystrtoul handle

* in general, trying to entierely avoid overflows in any computation
involving signed ints or longs is extremely involved. Fixed a few
simple cases where a compiler might be too clever (but that's all
guesswork).
* more overflow checks against bad data in marshal.c.
* 2.5 specific: fixed a number of places that were still confusing int
and Py_ssize_t. Some of them could potentially have caused
"real-world" breakage.
* list.pop(x): fixing overflow issues on x was messy. I just reverted
to PyArg_ParseTuple("n"), which does the right thing. (An obscure
test was trying to give a Decimal to list.pop()... doesn't make
sense any more IMHO)
* trying to write a few tests...

Remove file-locking in MH.pack() method.
This change looks massive but it's mostly a re-indenting after
removing some try...finally blocks.
Also adds a test case that does a pack() while the mailbox is locked; this
test would have turned up bugs in the original code on some platforms.
In both nmh and GNU Mailutils' implementation of MH-format mailboxes,
no locking is done of individual message files when renaming them.
The original mailbox.py code did do locking, which meant that message
files had to be opened. This code was buggy on certain platforms
(found through reading the code); there were code paths that closed
the file object and then called _unlock_file() on it.
Will backport to 25-maint once I see how the buildbots react to this patch.

Documentation for ctypes.
I think that 'generic operating system services' is the best category.
Note that the Doc/lib/libctypes.latex file is generated from reST sources.
You are welcome to make typo fixes, and I'll try to keep the reST sources
in sync, but markup changes would be lost - they should be fixed in the tool
that creates the latex file.
The conversion script is external/ctypes/docs/manual/mkpydoc.py.

SF bug #1473760 TempFile can hang on Windows.
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.

Make copy of test_mailbox.py. We'll still want to check the backward
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.

Add Gregory K. Johnson's revised version of mailbox.py (funded by
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.)

Move the PEP 343 documentation and implementation closer to the
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.

SF bug/patch #1433877: string parameter to ioctl not null terminated
The new char-array used in ioctl calls wasn't explicitly NUL-terminated;

has been somewhat elusive to start with.)

Define MAXPATHLEN to be at least PATH_MAX, if that's defined. Python uses
MAXPATHLEN-sized buffers for various output-buffers (like to realpath()),
and that's correct on BSD platforms, but not Linux (which uses PATH_MAX, and
does not define MAXPATHLEN.) Cursory googling suggests Linux is following a
newer standard than BSD, but in cases like this, who knows. Using the
greater of PATH_MAX and 1024 as a fallback for MAXPATHLEN seems to be the
most portable solution.

Rev 45706 renamed stuff in contextlib.py, but didn't rename
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.

After the patch (45590) to add extra debug stats to the gc module, Python
was crashing on OpenBSD due to:
Fatal Python error: Interpreter not initialized (version mismatch?)
This seems to occur due to calling collect() when initialized (in pythonrun.c)
is set to 0. Now, the import will occur in the init function which
shouldn't suffer this problem.

- 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.

about "%u", "%lu" and "%zu" formats.
Since PyString_FromFormat and PyErr_Format have exactly the same rules

with more LaTeX Fu changed one of them to just point to the other.
Their docs were way out of synch before this patch, and I just did a
mass copy+paste to repair that.

Rework the build system for osx applications:
* Don't use xcodebuild for building PythonLauncher, but use a normal unix
makefile. This makes it a lot easier to use the same build flags as for the
rest of python (e.g. make a universal version of python launcher)
* Convert the mac makefile-s to makefile.in-s and use configure to set makefile
variables instead of forwarding them as command-line arguments
* Add a C version of pythonw, that we you can use '#!/usr/local/bin/pythonw'
* Build IDLE.app using bundlebuilder instead of BuildApplet, that will allow
easier modification of the bundle contents later on.

Bug #1334662 / patch #1335972: int(string, base) wrong answers.
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.

speedup on the stringbench search/find/contains test, compared to 2.5a2.
for more on the algorithm, see:
http://effbot.org/zone/stringlib.htm
if you get weird results, you can disable the new algoritm by undefining
USE_FAST in Objects/unicodeobject.c.

Added a slew of test for string replace, based various corner cases from
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.

Heavily fiddled variant of patch #1442927: PyLong_FromString optimization.
``long(str, base)`` is now up to 6x faster for non-power-of-2 bases. The
largest speedup is for inputs with about 1000 decimal digits. Conversion
from non-power-of-2 bases remains quadratic-time in the number of input
digits (it was and remains linear-time for bases 2, 4, 8, 16 and 32).
Speedups at various lengths for decimal inputs, comparing 2.4.3 with
current trunk. Note that it's actually a bit slower for 1-digit strings:

Fixed problem identified by Georg. The special-case in-place code for replace
made a copy of the string using PyString_FromStringAndSize(s, n) and modify
the copied string in-place. However, 1 (and 0) character strings are shared
from a cache. This cause "A".replace("A", "a") to change the cached version
of "A" -- used by everyone.
Now may the copy with NULL as the string and do the memcpy manually. I've
added regression tests to check if this happens in the future. Perhaps
there should be a PyString_Copy for this case?

Changes to string.split/rsplit on whitespace to preallocate space in the
results list.
Originally it allocated 0 items and used the list growth during append. Now
it preallocates 12 items so the first few appends don't need list reallocs.
("Here are some words ."*2).split(None, 1) is 7% faster
("Here are some words ."*2).split() is is 15% faster
(Your milage may vary, see dealership for details.)
File parsing like this
for line in f:
count += len(line.split())
is also about 15% faster. There is a slowdown of about 3% for large
strings because of the additional overhead of checking if the append is
to a preallocated region of the list or not. This will be the rare case.
It could be improved with special case code but we decided it was not
useful enough.
There is a cost of 12*sizeof(PyObject *) bytes per list. For the normal
case of file parsing this is not a problem because of the lists have
a short lifetime. We have not come up with cases where this is a problem
in real life.
I chose 12 because human text averages about 11 words per line in books,
one of my data sets averages 6.2 words with a final peak at 11 words per
line, and I work with a tab delimited data set with 8 tabs per line (or
9 words per line). 12 encompasses all of these.
Also changed the last rstrip code to append then reverse, rather than
doing insert(0). The strip() and rstrip() times are now comparable.

substring split now uses /F's fast string matching algorithm.
(If compiled without FAST search support, changed the pre-memcmp test
to check the last character as well as the first. This gave a 25%
speedup for my test case.)
Rewrote the split algorithms so they stop when maxsplit gets to 0.
Previously they did a string match first then checked if the maxsplit
was reached. The new way prevents a needless string search.

Patch 1145039.
set_exc_info(), reset_exc_info(): By exploiting the
likely (who knows?) invariant that when an exception's
`type` is NULL, its `value` and `traceback` are also NULL,
save some cycles in heavily-executed code.
This is a "a kronar saved is a kronar earned" patch: the
speedup isn't reliably measurable, but it obviously does
reduce the operation count in the normal (no exception
raised) path through PyEval_EvalFrameEx().
The tim-exc_sanity branch tries to push this harder, but
is still blowing up (at least in part due to pre-existing
subtle bugs that appear to have no other visible
consequences!).
Not a bugfix candidate.
