46640 Patch #1454481:  Make thread stack size runtime tunable.
46647 Markup fix

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

svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH

followed by merging rev 46647 to the new branch.

Tim Peters 9b10f7e0cb Convert relevant dict internals to Py_ssize_t.
I don't have a box with nearly enough RAM, or an OS,
that could get close to tickling this, though (requires
a dict w/ at least 2**31 entries).

Fredrik Lundh 80f8e80c15 needforspeed: added Py_MEMCPY macro (currently tuned for Visual C only),
and use it for string copy operations.  this gives a 20% speedup on some
string benchmarks.

Richard Jones 7b9558d37d Conversion of exceptions over from faked-up classes to new-style C types. 2006-05-27 12:29:24 +00:00
Fredrik Lundh 7a83089c06 needforspeed: backed out the Py_LOCAL-isation of ceval; the massive in-
lining killed performance on certain Intel boxes, and the "aggressive"
macro itself gives most of the benefits on others.

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.

Fredrik Lundh 57640f5c57 needforspeed: added PY_LOCAL_AGGRESSIVE macro to enable "aggressive"

Fredrik Lundh 95e2a91615 use Py_LOCAL also for string and unicode objects 2006-05-26 11:38:15 +00:00
Fredrik Lundh b8b3c8e276 needforspeed: added Py_LOCAL macro, based on the LOCAL macro used
for SRE and others.  applied Py_LOCAL to relevant portion of ceval,
which gives a 1-2% speedup on my machine.  ymmv.

Tim Peters da53afa1b0 A new table to help string->integer conversion was added yesterday to
both mystrtoul.c and longobject.c.  Share the table instead.  Also
cut its size by 64 entries (they had been used for an inscrutable
trick originally, but the code no longer tries to use that trick).

Kristján Valur Jónsson f94323fbb4 Added a new macro, Py_IS_FINITE(X). On windows there is an intrinsic for this and it is more efficient than to use !Py_IS_INFINITE(X) && !Py_IS_NAN(X). No change on other platforms 2006-05-25 15:53:30 +00:00

Richard Jones 7c88dcc5ab Merge from rjones-funccall branch.
Applied patch zombie-frames-2.diff from sf patch 876206 with updates for
Python 2.5 and also modified to retain the free_list to avoid the 67%
slow-down in pybench recursion test. 5% speed up in function call pybench.

Martin v. Löwis a43190bc78 Patch #1492356: Port to Windows CE (patch set 1). 2006-05-22 09:15:18 +00:00
Thomas Wouters 9df4e6f673 - Add new Warning class, ImportWarning
- 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.

Thomas Wouters 1ddba60e3d 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.

Skip Montanaro 54e964d253 C++ compilation cleanup: Migrate declaration of
_PyObject_Call(Function|Method)_SizeT into Include/abstract.h.  This gets
them under the umbrella of the extern "C" { ... } block in that file.

Tim Peters de2acf6512 frame_traverse(): Use the standard Py_VISIT macro.
Py_VISIT:  cast the `op` argument to PyObject* when calling
`visit()`.  Else the caller has to pay too much attention to
this silly detail (e.g., frame_traverse needs to traverse
`struct _frame *` and `PyCodeObject *` pointers too).

Tim Peters 9d2ced8fa0 There were no comments explaining what Py_CLEAR() did or
why it's important.  Now there are ;-)

If someone else hasn't already, I'll add a Py_CLEAR cleanup
task to the TODO Wiki next.

Anthony Baxter 1cf3964fd1 C++ already defines a perfectly good 'bool'. Use that. 2006-04-11 07:23:05 +00:00
Phillip J. Eby 2ba96610bf SF Patch #1463867: Improved generator finalization to allow generators
that are suspended outside of any try/except/finally blocks to be
garbage collected even if they are part of a cycle.  Generators that
suspend inside of an active try/except or try/finally block (including
those created by a ``with`` statement) are still not GC-able if they
are part of a cycle, however.
