This can cause core dumps when Python runs. Python relies on the 754-
(and C99-) mandated default "non-stop" mode for FP exceptions. This
patch from Ben Laurie disables at least one FP exception on FreeBSD at
Python startup time.
HTML tarball and use it to create a documentation tree readable and
searchable with Apple Help Viewer. The documentation also shows up in
Project Builder (if you add Python.framework to your project).
SF 560379: Karatsuba multiplication.
Lots of things were changed from that. This needs a lot more testing,
for correctness and speed, the latter especially when bit lengths are
unbalanced. For now, the Karatsuba code gets invoked if and only if
envar KARAT exists.
explicit comparison function case: use PyObject_Call instead of
PyEval_CallObject. Same thing in context, but gives a 2.4% overall
speedup when sorting a list of ints via list.sort(__builtin__.cmp).
In a fresh interpreter, type.mro(tuple) would segfault, because
PyType_Ready() isn't called for tuple yet. To fix, call
PyType_Ready(type) if type->tp_dict is NULL.
Due to the bizarre definition of _PyLong_Copy(), creating an instance
of a subclass of long with a negative value could cause core dumps
later on. Unfortunately it looks like the behavior of _PyLong_Copy()
is quite intentional, so the fix is more work than feels comfortable.
This fix is almost, but not quite, the code that Naofumi Honda added;
in addition, I added a test case.
rexec.
When using a restricted environment, imports of copy will fail with an
AttributeError when trying to access types.CodeType.
Bugfix candidate (all the way back to 1.5.3, but at least 2.1.3 and
2.2.1).
A file-static "threads" dict mapped thread IDs to Windows handles, but
was never referenced, and entries never got removed. This gets rid of
the YAGNI-dict entirely.
Bugfix candidate.
Instead of sending the real user and host, use "anonymous@" (i.e. no
host name at all!) as the default anonymous FTP password. This avoids
privacy violations.
binascii_b2a_base64(): We didn't allocate enough buffer space for very
short inputs (e.g., a 1-byte input can produce a 5-byte output, but we
only allocated 2 bytes). I expect that malloc overheads absorbed the
overrun in practice, but computing a correct upper bound is a very simple
change.
type.__module__ behavior.
This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this). Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right. Apologies if they're
not. This also touches the weakref docs, which contains a sample type
object initializer. It also touches the mmap test output, because the
mmap type's repr is included in that output. It touches object.h to
put the correct description in a comment.
Anthony Roach.
Release the global interpreter lock around platform spawn calls.
Bugfix candidate? Hard to say; I favor "yes, bugfix".
These clearly *should* have been releasing the GIL all along, if for no
other reason than compatibility with the similar os.system(). But it's
possible some program out there is (a) multithreaded, (b) calling a spawn
function with P_WAIT, and (c) relying on the spawn call to block all their
threads until the spawned program completes. I think it's very unlikely
anyone is doing that on purpose, but someone may be doing so by accident.
Bugfix candidate.
tb_displayline(): the sprintf format was choking off the file name, but
used plain %s for the function name (which can be arbitrarily long).
Limit both to 500 chars max.
Removed "#undef HAVE_HYPOT" line from Borland config, as suggested.
Whether this will break some other Borland usage is a good question I
can't answer.
Replace some tortuous code that was trying to be clever but forgot to
DECREF the key and value, by more longwinded but obviously correct
code.
(Inspired by but not copying the fix from SF patch #475033.)
The C-code in fileobject.readinto(buffer) which parses
the arguments assumes that size_t is interchangeable
with int:
size_t ntodo, ndone, nnow;
if (f->f_fp == NULL)
return err_closed();
if (!PyArg_Parse(args, "w#", &ptr, &ntodo))
return NULL;
This causes a problem on Alpha / Tru64 / OSF1 v5.1
where size_t is a long and sizeof(long) != sizeof(int).
The patch I'm proposing declares ntodo as an int. An
alternative might be to redefine w# to expect size_t.
[We can't change w# because there are probably third party modules
relying on it. GvR]
1. configure doesn't handle HP-UX release numbers
(e.g., B.11.00), resulting in MACHDEP = "hpuxB".
2. After checking for wchar.h, configure doesn't
include it when checking the size of wchar_t.
(Python 2.2b1 on HP-UX 11.00)
Generalize PyLong_AsLongLong to accept int arguments too. The real point
is so that PyArg_ParseTuple's 'L' code does too. That code was
undocumented (AFAICT), so documented it.
LettError, Erik van Blokland, http://www.letterror.com/
the Python Windows installer finally has an attractive Pythonic bitmap
to delight the senses and dampen the fears of the millions and millions of
eager new Windows users anticipating their first Python programming joy.
Always knew Mac users secretly wanted to switch to Windows <wink>.
Armin Rigo pointed out that the way the line-# table got built didn't work
for lines generating more than 255 bytes of bytecode. Fixed as he
suggested, plus corresponding changes to pyassem.py, plus added some
long overdue docs about this subtle table to compile.c.
Bugfix candidate (line numbers may be off in tracebacks under -O).
SF patch #103683: Alternative dll version resources.
Changes similar to the patch. MarkH should review.
File version and Product version text strings now 2.1a2.
64-bit file and product version numbers are now
PY_MAJOR_VERSION, PY_MINOR_VERSION, messy, PYTHON_API_VERSION
where
messy = PY_MICRO_VERSION*1000 + PY_RELEASE_LEVEL*10 + PY_RELEASE_SERIAL
Updated company name to "Digital Creations 2".
Copyright now lists Guido; "C in a circle" symbol used instead of (C).
Comments added so this is less likely to get flubbed again, and
#if/#error guys added to trigger if the version number manipulations
above overflow.
