Antoine Pitrou f8387af262 Issue #4688: Add a heuristic so that tuples and dicts containing only 
untrackable objects are not tracked by the garbage collector. This can
reduce the size of collections and therefore the garbage collection overhead
on long-running programs, depending on their particular use of datatypes.

(trivia: this makes the "binary_trees" benchmark from the Computer Language
Shootout 40% faster)

Mark Dickinson f35f8044e4 Rewrite Py_ARITHMETIC_RIGHT_SHIFT so that it's valid for all signed 
integer types T, not just those for which "unsigned T" is legal.

Mark Dickinson efc82f7e8e Issue #4258: Use 30-bit digits for Python longs, on 64-bit platforms. 
Backport of r70459.
 2009-03-20 15:51:55 +00:00
Jeffrey Yasskin 68d6852006 Backport r69961 to trunk, replacing JUMP_IF_{TRUE,FALSE} with 
POP_JUMP_IF_{TRUE,FALSE} and JUMP_IF_{TRUE,FALSE}_OR_POP. This avoids executing
a POP_TOP on each conditional and sometimes allows the peephole optimizer to
skip a JUMP_ABSOLUTE entirely. It speeds up list comprehensions significantly.

Benjamin Peterson 5781f32b4f remove some PyBytes_* aliases that are not in 3.x 2009-02-16 21:09:09 +00:00
Mark Dickinson bcf6b18eb7 A few more minor fixes in longobject.c 2009-02-15 15:48:39 +00:00
Mark Dickinson 2ffb26fb83 Issue #5260: Various portability and standards compliance fixes, optimizations 
and cleanups in Objects/longobject.c.  The most significant change is that
longs now use less memory:  average savings are 2 bytes per long on 32-bit
systems and 6 bytes per long on 64-bit systems.  (This memory saving already
exists in py3k.)

Hirokazu Yamamoto bcd3ea86a3 Issue #5204: Define _PyVerify_fd on VC6 to make 
test_fdopen (test_os.py) pass.

Kristján Valur Jónsson 6a743d3694 Issue 4804. Add a function to test the validity of file descriptors on Windows, and stop using global runtime settings to silence the warnings / assertions. 2009-02-10 13:32:24 +00:00
Mark Dickinson c97c9096ed Issue #4575: fix Py_IS_INFINITY macro to work correctly on x87 FPUs. 
It now forces its argument to double before testing for infinity.

Raymond Hettinger b516370bcb Issue 1242657: list(obj) can swallow KeyboardInterrupt. 2009-02-02 21:50:13 +00:00
Amaury Forgeot d'Arc a40d573664 #3720: Interpreter crashes when an evil iterator removes its own next function. 
Now the slot is filled with a function that always raises.

Will not backport: extensions compiled with 2.6.x would not run on 2.6.0.

Jeffrey Yasskin d89f5b20b2 Fix issue 4884, preventing a crash in the socket code when python is compiled 
with llvm-gcc and run with a glibc <2.10.

Marc-André Lemburg 3741bfdd3c Fix #4846 (Py_UNICODE_ISSPACE causes linker error) by moving the declaration 
into the extern "C" section.

Add a few more comments and apply some minor edits to make the file contents
fit the original structure again.

Mark Dickinson 1bf6401ab2 Use C99 'isfinite' macro in preference to BSD-derived 'finite' function. 2009-01-04 19:53:00 +00:00
Mark Dickinson 0ebfedf38e Fix HAVE_DECL_ISINF/ISNAN test (again). 2009-01-04 17:02:05 +00:00
Mark Dickinson 41fbae1ac9 Oops. Need to check not only that HAVE_DECL_ISINF is defined, but also 
that it's equal to 1.  (If isinf isn't defined, HAVE_DECL_ISINF is
defined to be 0, rather than being undefined.)
 2009-01-04 16:06:40 +00:00
Mark Dickinson d181e3a246 isinf and isnan are macros, not functions; fix configure script 
to use AC_CHECK_DECLS instead of AC_CHECK_FUNCS for these.
(See discussion in issue #4506)

Antoine Pitrou d4ae97bc38 #3668: When PyArg_ParseTuple correctly parses a s* format, but raises an 
exception afterwards (for a subsequent parameter), the user code will
not call PyBuffer_Release() and memory will leak.

Antoine Pitrou 0668c62677 Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to 
match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
mechanism. In the process, fix a bug where isinstance() and issubclass(),
when given a tuple of classes as second argument, were looking up
__instancecheck__ / __subclasscheck__ on the tuple rather than on each
type object.

Gregory P. Smith 0470bab697 Issue #2620: Overflow checking when allocating or reallocating memory 
was not always being done properly in some python types and extension
modules.  PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
all been updated to perform better checks and places in the code that
would previously leak memory on the error path when such an allocation
failed have been fixed.
