Tim Peters 8f422461b4 Fix for bug 113934. string*n and unicode*n did no overflow checking at
all, either to see whether the # of chars fit in an int, or that the
amount of memory needed fit in a size_t.  Checking these is expensive, but
the alternative is silently wrong answers (as in the bug report) or
core dumps (which were easy to provoke using Unicode strings).

Fredrik Lundh df84675f93 changed \x to consume exactly two hex digits, also for unicode
strings.  closes PEP-223.

also added \U escape (eight hex digits).

Guido van Rossum bb8be93a50 Rewritten some pieces of PyNumber_InPlaceAdd() for clarity. 2000-09-01 23:27:32 +00:00
Thomas Wouters cadd5b6b58 Fix grouping, again. This time properly :-) Sorry, guys. 2000-09-01 07:53:25 +00:00
Jeremy Hylton b709df3810 refactor __del__ exception handler into PyErr_WriteUnraisable
add sanity check to gc: if an exception occurs during GC, call
PyErr_WriteUnraisable and then call Py_FatalEror.

Guido van Rossum 04127de434 Add parens suggested by gcc -Wall. 2000-09-01 02:39:00 +00:00
Fred Drake 1bff34ab96 Slight performance hack that also avoids requiring the existence of thread
state for dictionaries that have only been indexed by string keys.

See the comments in SourceForge for more.

This closes SourceForge patch #101309.

Fred Drake c88b99ce06 Clear errors raised by PyObject_Compare() without losing any existing
exception context.  This avoids improperly propogating errors raised by
a user-defined __cmp__() by a subsequent lookup operation.

This patch does *not* include the performance enhancement patch for
dictionaries with string keys only; that will be checked in separately.

This closes SourceForge patch #101277 and bug #112558.
2000-08-31 19:04:07 +00:00
Thomas Wouters 6b958f7d7b Fix grouping: this is how I intended it, misguided as I was in boolean
operator associativity.

Fred Drake 8ce159aef5 Peter Schneider-Kamp <nowonder@nowonder.de>:
Remove some of GCC's warning in -Wstrict-prototypes mode.

This closes SourceForge patch #101342.
2000-08-31 05:18:54 +00:00
Fred Drake 562f62aa9b Removed compiler warning about wanting explicit grouping around &&
expression next to a || expression; this is a readability-inspired
warning from GCC.

Marc-André Lemburg 6ef68b5b01 Fix to bug [ Bug #111860 ] file.writelines() crashes.
file.writelines() now tries to emulate the behaviour of file.write()
as closely as possible. Due to the problems with releasing the
interpreter lock the solution isn't exactly optimal, but still better
than not supporting the file.write() semantics at all.

Thomas Wouters 1de2a79a48 Call PyErr_Clear() to clear the AttributeError raised by GetAttr. 2000-08-25 10:47:46 +00:00
Thomas Wouters e289e0bd0c Support for the in-place operations introduced by augmented assignment. Only
the list object supports this currently, but other candidates are
gladly accepted (like arraymodule and such.)
2000-08-24 20:08:19 +00:00
Thomas Wouters e266e42c9c Addendum to previous change: now that 'f' is not unconditionally
initialized in the 'if (..)', do so manually.
2000-08-23 23:31:34 +00:00
Thomas Wouters bf6cfa5f8e Add extra check on whether 'tp_as_number' is still non-NULL after coercion,
in the PyNumber_* functions. Also, remove unnecessary tests from
PyNumber_Multiply: after BINOP(), neither argument can be an instance.

Jack Jansen d49cbe1060 Added PyOS_CheckStack call to PyObject_Compare
Lowered the recursion limit on compares to 60 (one recursion depth can
take a whopping 2K of stack space when running test_b1!)

Barry Warsaw ce4dc41b1a PyUnicode_AsUTF8String(): /F picks up what I missed: the local var
`str' is no longer necessary.  Gotta turn on -Wall!
2000-08-18 19:30:40 +00:00
Barry Warsaw 2dd4abf277 PyUnicode_AsUTF8String(): Don't need to explicitly incref str since
PyUnicode_EncodeUTF8() already returns the created object with the
proper reference count.  This fixes an Insure reported memory leak.
2000-08-18 06:58:15 +00:00
Barry Warsaw 9d23a4eb03 make_pair(): When comparing the pointers, they must be cast to integer
types (i.e. Py_uintptr_t, our spelling of C9X's uintptr_t).  ANSI
specifies that pointer compares other than == and != to non-related
structures are undefined.  This quiets an Insure portability warning.
2000-08-18 05:01:19 +00:00
Barry Warsaw 67c1a04bbb PyFloat_FromString(): Move s_buffer[] up to the top-level function
scope.  Previously, s_buffer[] was defined inside the
PyUnicode_Check() scope, but referred to in the outer scope via
assignment to s.  This quiets an Insure portability warning.
2000-08-18 05:00:03 +00:00
Barry Warsaw dc55d715bb PyInstance_DoBinOp(): When comparing the pointers, they must be cast

Thomas Wouters 1d75a79c00 Apply SF patch #101029: call __getitem__ with a proper slice object if there
is no __getslice__ available. Also does the same for C extension types.
Includes rudimentary documentation (it could use a cross reference to the
section on slice objects, I couldn't figure out how to do that) and a test
suite for all Python __hooks__ I could think of, including the new
behaviour.

Barry Warsaw 4df762ff98 Insure properly identifies the `interned' dictionary as leaking at
shutdown time, but CVS log entry for revision 2.45 explains why this
is so.  Simply include a comment so we don't have to re-figure it out
again 5 years from now.

Tim Peters 39dce29365 Fix for http://sourceforge.net/bugs/?func=detailbug&bug_id=111866&group_id=5470.
This was a misleading bug -- the true "bug" was that hash(x) gave an error
return when x is an infinity.  Fixed that.  Added new Py_IS_INFINITY macro to
pyport.h.  Rearranged code to reduce growing duplication in hashing of float and
complex numbers, pushing Trent's earlier stab at that to a logical conclusion.
Fixed exceedingly rare bug where hashing of floats could return -1 even if there
wasn't an error (didn't waste time trying to construct a test case, it was simply
obvious from the code that it *could* happen).  Improved complex hash so that
hash(complex(x, y)) doesn't systematically equal hash(complex(y, x)) anymore.

Marc-André Lemburg b7520774e2 Fixed a couple of instances where a 0-length string was being
resized after creation. 0-length strings are usually shared
and _PyString_Resize() fails on these shared strings.

Fixes [ Bug #111667 ] unicode core dump.

Trent Mick 20abf573ef Clean up warning from Monterey compiler.
Properly end a comment block. It was terminated fine later but by a subsequent
block and. It was also in #if 0. This patch is so trivial I can't believe I am
talking about it. :)
2000-08-12 22:14:34 +00:00
Trent Mick a248fb605f Clean up a warning on Win64. The downcast of the strlen size_t
return value to int is safe here because it previously checked that
there will be no overflow.
2000-08-12 21:37:39 +00:00
Trent Mick 8a74e5fc2c Add the current Win64 compiler to the list of those that need the
huge switch statement broken up. This will probably not be necessary when
the Win64 compiler matures.
2000-08-12 19:37:27 +00:00
Trent Mick f29f47b38b Add largefile support for Linux64 and WIn64. Add test_largefile and some minor
change to regrtest.py to allow optional running of test_largefile ('cause it's
slow on Win64).

Guido van Rossum 164452cec4 Barry's patch to implement the new setdefault() method. 2000-08-08 16:12:54 +00:00
Marc-André Lemburg e5034378cc Removing UTF-16 aware Unicode comparison code. This kind of compare
function (together with other locale aware ones) should into a new collation
support module. See python-dev for a discussion of this removal.

Note: This patch should also be applied to the 1.6 branch.

Tim Peters 72d421b75c Boost buffer sizes in the absence of snprintf on Windows.
Ensure that # of args to sprintf always matches # of format specifiers.
2000-08-04 03:05:40 +00:00
Fred Drake c76e0e5679 snprintf() is not portable, so continue to use sprintf() until a portable
snprintf() is available.

Marc-André Lemburg bff879cabb This patch finalizes the move from UTF-8 to a default encoding in
the Python Unicode implementation.

The internal buffer used for implementing the buffer protocol
is renamed to defenc to make this change visible. It now holds the
default encoded version of the Unicode object and is calculated
on demand (NULL otherwise).

Since the default encoding defaults to ASCII, this will mean that
Unicode objects which hold non-ASCII characters will no longer
work on C APIs using the "s" or "t" parser markers. C APIs must now
explicitly provide Unicode support via the "u", "U" or "es"/"es#"
parser markers in order to work with non-ASCII Unicode strings.

(Note: this patch will also have to be applied to the 1.6 branch
 of the CVS tree.)

Fred Drake 2b83b4601f Remove the tp_print handler.
Revise the tp_repr handler to produce a more "minimal" presentation.
Make the tolist() method use PyArg_ParseTuple() and provide a docstring.

Guido van Rossum c4a19e7fe9 Remobe beopen/cnri/cwi copyrights, according to CNRI instructions.
This doesn't change the copyright status for these files -- just the
markings!  Doing it on the main branch for these three files for which
the HEAD revision was pushed back into 1.6.
2000-08-03 16:42:14 +00:00
Guido van Rossum 16b1ad9c7d Changing the CNRI copyright notice according to CNRI's instructions.
This is a notice without a date, which apparently is not a claim to
copyright but only advice to the reader.  IANAL. :-)
