Raymond Hettinger b423f02aa5 Let marshal build-up sets and frozensets one element at a time.
Saves the unnecessary creation of a tuple as intermediate container.

Amaury Forgeot d'Arc 16570f59ca #1920: when considering a block starting by "while 0", the compiler optimized the
whole construct away, even when an 'else' clause is present::

    while 0:
        print("no")
    else:
        print("yes")

did not generate any code at all.

Now the compiler emits the 'else' block, like it already does for 'if' statements.

Will backport.

Gregory P. Smith 2778c999e3 Provide a sanity check during PyThreadState_DeleteCurrent() and
PyThreadState_Delete() to avoid an infinite loop when the tstate list
is messed up and has somehow becomes circular and does not contain the
current thread.

I don't know how this happens but it does, *very* rarely.  On more than
one hardware platform.  I have not been able to reproduce it manually.

Attaching to a process where its happening: it has always been in an
infinite loop over a single element tstate list that is not the tstate
we're looking to delete.  It has been in t_bootstrap()'s call to
PyThreadState_DeleteCurrent() as a pthread is exiting.

Jeffrey Yasskin 9871d8fe22 Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
 * Revert round to its 2.6 behavior (half away from 0).
 * Because round, floor, and ceil always return float again, it's no
   longer necessary to have them delegate to __xxx___, so I've ripped
   that out of their implementations and the Real ABC. This also helps
   in implementing types that work in both 2.6 and 3.0: you return int
   from the __xxx__ methods, and let it get enabled by the version
   upgrade.
 * Make pow(-1, .5) raise a ValueError again.

Amaury Forgeot d'Arc e0b7695286 Partial port of r59682 from py3k.
On Windows, when import fails to load a dll module, the message says
"error code 193" instead of a more informative text.

It turns out that FormatMessage needs additional parameters for some error codes.
For example: 193 means "%1 is not a valid Win32 application".
Since it is impossible to know which parameter to pass, we use
FORMAT_MESSAGE_IGNORE_INSERTS to get the raw message, which is still better
than the number.

Jeffrey Yasskin 2f3c16be73 Backport PEP 3141 from the py3k branch to the trunk. This includes r50877 (just
the complex_pow part), r56649, r56652, r56715, r57296, r57302, r57359, r57361,
r57372, r57738, r57739, r58017, r58039, r58040, and r59390, and new
documentation. The only significant difference is that round(x) returns a float
to preserve backward-compatibility. See http://bugs.python.org/issue1689.

Raymond Hettinger fd7ed407d7 Give meaning to the oparg for BUILD_MAP: estimated size of the dictionary.
Allows dictionaries to be pre-sized (upto 255 elements) saving time lost
to re-sizes with their attendant mallocs and re-insertions.

Has zero effect on small dictionaries (5 elements or fewer), a slight
benefit for dicts upto 22 elements (because they had to resize once
anyway), and more benefit for dicts upto 255 elements (saving multiple
resizes during the build-up and reducing the number of collisions on
the first insertions).  Beyond 255 elements, there is no addional benefit.
2007-12-18 21:24:09 +00:00

Amaury Forgeot d'Arc 025c347d61 Issue #1402: PyInterpreterState_Clear() may still invoke user code
(in deallocation of running threads, for example), so the PyGILState_Release()
function must still be functional.
On the other hand, _PyGILState_Fini() only frees memory, and can be called later.

Backport candidate, but only after some experts comment on it.

Christian Heimes e8954f8ce7 Backport of the PCbuild9 directory from the py3k branch.
I've finished the last task for the PCbuild9 directory today. I don't think there is much left to do. Now you can all play around with the shiny new VS 2008 and try the PGO builds. I was able to get a speed improvement of about 10% on py3k.
Have fun! :)

Nick Coghlan 327a39b047 Patch #1739468: Directories and zipfiles containing __main__.py are now executable 2007-11-18 11:56:28 +00:00
Amaury Forgeot d'Arc 0d75f09177 Merge from py3k branch:
Correction for issue1265 (pdb bug with "with" statement).

When an unfinished generator-iterator is garbage collected, PyEval_EvalFrameEx
is called with a GeneratorExit exception set.  This leads to funny results
if the sys.settrace function itself makes use of generators.
A visible effect is that the settrace function is reset to None.
Another is that the eventual "finally" block of the generator is not called.

It is necessary to save/restore the exception around the call to the trace
function.

This happens a lot with py3k: isinstance() of an ABCMeta instance runs
    def __instancecheck__(cls, instance):
        """Override for isinstance(instance, cls)."""
        return any(cls.__subclasscheck__(c)
                   for c in {instance.__class__, type(instance)})
which lets an opened generator expression each time it returns True.

Backport candidate, even if the case is less frequent in 2.5.

Kristján Valur Jónsson f030394de3 Fix problems in x64 build that were discovered by the testsuite:
- Reenable modules on x64 that had been disabled aeons ago for Itanium.
- Cleared up confusion about compilers for 64 bit windows.  There is only Itanium and x64.  Added macros MS_WINI64 and MS_WINX64 for those rare cases where it matters, such as the disabling of modules above.
- Set target platform (_WIN32_WINNT and WINVER) to 0x0501 (XP) for x64, and 0x0400 (NT 4.0) otherwise, which are the targeted minimum platforms.
- Fixed thread_nt.h.  The emulated InterlockedCompareExchange function didn´t work on x64, probaby due to the lack of a "volatile" specifier.  Anyway, win95 is no longer a target platform.
- Itertools module used wrong constant to check for overflow in count()
- PyInt_AsSsize_t couldn't deal with attribute error when accessing the __long__ member.
- PyLong_FromSsize_t() incorrectly specified that the operand were unsigned.

With these changes, the x64 passes the testsuite, for those modules present.

Thomas Wouters afea529088 SF patch #1630975: Fix crash when replacing sys.stdout in sitecustomize
When running the interpreter in an environment that would cause it to set
stdout/stderr/stdin's encoding, having a sitecustomize that would replace
them with something other than PyFile objects would crash the interpreter.
Fix it by simply ignoring the encoding-setting for non-files.

This could do with a test, but I can think of no maintainable and portable
way to test this bug, short of adding a sitecustomize.py to the buildsystem
and have it always run with it (hmmm....)

Armin Rigo 7ccbca93a2 Forward-port of r52136,52138: a review of overflow-detecting code.
* unified the way intobject, longobject and mystrtoul handle
  values around -sys.maxint-1.

* 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...

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.

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.

an operation on a signed integral type overflows, and PyOS_strtol()
did several formally undefined things of that nature on signed
longs.  Some version of gcc apparently tries to exploit that now,
and PyOS_strtol() could fail to detect overflow then.

Tried to repair all that, although it seems at least as likely to me
that we'll get screwed by bad platform definitions for LONG_MIN
and/or LONG_MAX now.  For that reason, I don't recommend backporting
this.

Note that I have no box on which this makes a lick of difference --
can't really test it, except to note that it didn't break anything
on my boxes.

Silent change:  PyOS_strtol() used to return the hard-coded 0x7fffffff
in case of overflow.  Now it returns LONG_MAX.  They're the same only on
32-bit boxes (although C doesn't guarantee that either ...).

Tim Peters 112aad3630 SF bug 1524317: configure --without-threads fails to build
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.

Tim Peters 02f1d0dc78 _PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed.  In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)).  So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.
2006-06-06 00:25:07 +00:00
Brett Cannon 4f7a7220c1 Add 3 more bytes to a buffer to cover constants in string and null byte on top of 10 possible digits for an int.

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

followed by merging rev 46647 to the new branch.

Tim Peters 7df5e7f4b2 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.

Tim Peters b713ec2531 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.
