Alex Martelli 348dc88097 Reverting the patch that tried to fix the issue whereby x**2 raises
OverflowError while x*x succeeds and produces infinity; apparently
these inconsistencies cannot be fixed across ``all'' platforms and
there's a widespread feeling that therefore ``every'' platform
should keep suffering forevermore.  Ah well.
2006-08-23 22:17:59 +00:00
Alex Martelli 20362a820b x**2 should about equal x*x (including for a float x such that the result is
inf) but didn't; added a test to test_float to verify that, and ignored the
ERANGE value for errno in the pow operation to make the new test pass (with
help from Marilyn Davis at the Google Python Sprint -- thanks!).

Neal Norwitz 17753ecbfa Patch #1541585: fix buffer overrun when performing repr() on
a unicode string in a build with wide unicode (UCS-4) support.

This code could be improved, so add an XXX comment.

Neal Norwitz 076d1e0c0b Fix a couple of ssize-t issues reported by Alexander Belopolsky on python-dev 2006-08-21 18:20:10 +00:00
Neal Norwitz 7fd9607bad Move initialization to after the asserts for non-NULL values.
Klocwork 286-287.

(I'm not backporting this, but if someone wants to, feel free.)

Neal Norwitz 6cbb726539 Move initialization of interned strings to before allocating the
object so we don't leak op.  (Fixes an earlier patch to this code)

Marc-André Lemburg 3a457790c7 Correct an accidentally removed previous patch. 2006-08-14 12:57:27 +00:00
Marc-André Lemburg 040f76b79c Slightly revised version of patch #1538956:
Replace UnicodeDecodeErrors raised during == and !=
compares of Unicode and other objects with a new
UnicodeWarning.

All other comparisons continue to raise exceptions.
Exceptions other than UnicodeDecodeErrors are also left
untouched.

Neal Norwitz af33f2d571 Can't return NULL from a void function. If there is a memory error,
about the best we can do is call PyErr_WriteUnraisable and go on.
We won't be able to do the call below either, so verify delstr is valid.

Neal Norwitz 1872b1c01f Fix a couple of bugs exposed by the new __index__ code. The 64-bit buildbots
were failing due to inappropriate clipping of numbers larger than 2**31
with new-style classes. (typeobject.c)  In reviewing the code for classic
classes, there were 2 problems.  Any negative value return could be returned.
Always return -1 if there was an error.  Also make the checks similar
with the new-style classes.  I believe this is correct for 32 and 64 bit
boxes, including Windows64.

Add a test of classic classes too.

Neal Norwitz 8a87f5d37e Patch #1538606, Patch to fix __index__() clipping.
I modified this patch some by fixing style, some error checking, and adding
XXX comments.  This patch requires review and some changes are to be expected.
I'm checking in now to get the greatest possible review and establish a
baseline for moving forward.  I don't want this to hold up release if possible.

Neal Norwitz 421c1319ad Whoops, how did that get in there. :-) Revert all the parts of 51227 that were not supposed to go it. Only Modules/_ctypes/cfields.c was supposed to be changed 2006-08-12 02:12:30 +00:00

2006-08-12 02:06:34 +00:00
Neal Norwitz 6f5ff3f3eb Klocwork made another run and found a bunch more problems.
This is the first batch of fixes that should be easy to verify based on context.

This fixes problem numbers: 220 (ast), 323-324 (symtable),
321-322 (structseq), 215 (array), 210 (hotshot), 182 (codecs), 209 (etree).

Martin v. Löwis ab2f8f7bd5 __hash__ may now return long int; the final hash
value is obtained by invoking hash on the long int.
Fixes #1536021.

Thomas Heller ab1049c046 memcmp() can return values other than -1, 0, and +1 but tp_compare

Georg Brandl b0061c8e93 Remove "non-mapping" and "non-sequence" from TypeErrors raised by
PyMapping_Size and PySequence_Size.

Because len() tries first sequence, then mapping size, it will always
raise a "non-mapping object has no len" error which is confusing.

Neal Norwitz 101bac205d Closure can't be NULL at this point since we know it's a tuple.

Neal Norwitz e1fdb32ff2 Handle allocation failures gracefully. Found with failmalloc.
Many (all?) of these could be backported.
2006-07-21 05:32:28 +00:00
Neal Norwitz 1adbb50701 Move the initialization of some pointers earlier. The problem is
that if we call Py_DECREF(frame) like we do if allocating locals fails,
frame_dealloc() will try to use these bogus values and crash.

Neal Norwitz 48808a1d6c Add some asserts that we got good params passed 2006-07-21 05:29:58 +00:00
Neal Norwitz 04e39ec815 otherset is known to be non-NULL based on checks before and DECREF after.
DECREF otherset rather than XDECREF in error conditions too.

Reported by Klockwork #154.

Neal Norwitz b337bb541b Stop INCREFing name, then checking if it's NULL. name (f_name) should never
be NULL so assert it.  Fix one place where we could have passed NULL.

Reported by Klocwork #66.
2006-07-17 00:55:45 +00:00
Neal Norwitz ee4cc698ca PyFunction_SetDefaults() is documented as taking None or a tuple.
A NULL would crash the PyTuple_Check().  Now make NULL return a SystemError.

Neal Norwitz 4b0a315c31 Use sizeof(buffer) instead of duplicating the constants to ensure they won't
be wrong.

The real change is to pass (bufsz - 1) to PyOS_ascii_formatd and 1
to strncat.  strncat copies n+1 bytes from src (not dest).

Reported by Klocwork #58.

Neal Norwitz ef02b9e144 a & b were dereffed above, so they are known to be valid pointers.
z is known to be NULL, nothing to DECREF.

Kristján Valur Jónsson 74c3ea0a0f Fix build problems with the platform SDK on windows. It is not sufficient to test for the C compiler version when determining if we have the secure CRT from microsoft. Must test with an undocumented macro, __STDC_SECURE_LIB__ too. 2006-07-03 14:59:05 +00:00

Armin Rigo 53c1692f6a Fix for an obscure bug introduced by revs 46806 and 46808, with a test.
The problem of checking too eagerly for recursive calls is the
following: if a RuntimeError is caused by recursion, and if code needs
to normalize it immediately (as in the 2nd test), then
PyErr_NormalizeException() needs a call to the RuntimeError class to
instantiate it, and this hits the recursion limit again...  causing
PyErr_NormalizeException() to never finish.

Moved this particular recursion check to slot_tp_call(), which is not
involved in instantiating built-in exceptions.

Backport candidate.
