Brett Cannon 5cd0fca9d8 Complete deprecation of BaseException.message. Some subclasses were directly
accessing the message attribute instead of using the descriptor.

Brett Cannon 229cee2d3d Deprecate BaseException.message as per PEP 352. 2007-05-05 01:34:02 +00:00
Georg Brandl c02e13122b Add some missing NULL checks which trigger crashes on low-memory conditions.
Found by Victor Stinner. Will backport when 2.5 branch is unfrozen.

Neal Norwitz ee3a1b5244 Variation of patch # 1624059 to speed up checking if an object is a subclass
of some of the common builtin types.

Use a bit in tp_flags for each common builtin type.  Check the bit
to determine if any instance is a subclass of these common types.
The check avoids a function call and O(n) search of the base classes.
The check is done in the various Py*_Check macros rather than calling
PyType_IsSubtype().

All the bits are set in tp_flags when the type is declared
in the Objects/*object.c files because PyType_Ready() is not called
for all the types.  Should PyType_Ready() be called for all types?
If so and the change is made, the changes to the Objects/*object.c files
can be reverted (remove setting the tp_flags).  Objects/typeobject.c
would also have to be modified to add conditions
for Py*_CheckExact() in addition to each the PyType_IsSubtype check.

Thomas Heller df08f0b9a0 WindowsError.str should display the windows error code,
not the posix error code; with test.
Fixes #1576174.

Will backport to release25-maint.

Georg Brandl 3267d28f9d Bug #1566800: make sure that EnvironmentError can be called with any
number of arguments, as was the case in Python 2.4.

Brett Cannon f6aa86e33b Allow exceptions to be directly sliced again
(e.g., ``BaseException(1,2,3)[0:2]``).

Discovered in Python 2.5.0 by Thomas Heller and reported to python-dev.  This
should be backported to 2.5 .

Brett Cannon ca2ca79d23 Remove the __unicode__ method from exceptions. Allows unicode() to be called
on exception classes.  Would require introducing a tp_unicode slot to make it
work otherwise.

Fixes bug #1551432 and will be backported.

Georg Brandl 38f6237dfe Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
Also make sure that every exception class has __module__ set to
'exceptions'.

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.

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
Kristján Valur Jónsson f608317061 Fix the CRT argument error handling for VisualStudio .NET 2005. Install a CRT error handler and disable the assertion for debug builds. This causes CRT to set errno to EINVAL.
This update fixes crash cases in the test suite where the default CRT error handler would cause process exit.

Thomas Wouters c1282eef0c Make last patch valid C89 so Windows compilers can deal with it. 2006-05-28 21:32:12 +00:00

subclasses.

Georg Brandl 43ab100cdc Fix refleaks in UnicodeError get and set methods. 2006-05-28 20:57:09 +00:00
Michael W. Hudson 96495ee6dd Quality control, meet exceptions.c, round two.
Make some functions that should have been static static.

Fix a bunch of refleaks by fixing the definition of
MiddlingExtendsException.

Remove all the __new__ implementations apart from
BaseException_new.  Rewrite most code that needs it to cope with
NULL fields (such code could get excercised anyway, the
__new__-removal just makes it more likely).  This involved
editing the code for WindowsError, which I can't test.

This fixes all the refleaks in at least the start of a regrtest
-R :: run.

Michael W. Hudson 22a80e7cb0 Quality control, meet exceptions.c.
Fix a number of problems with the need for speed code:

One is doing this sort of thing:

    Py_DECREF(self->field);
    self->field = newval;
    Py_INCREF(self->field);

without being very sure that self->field doesn't start with a
value that has a __del__, because that almost certainly can lead
to segfaults.

As self->args is constrained to be an exact tuple we may as well
exploit this fact consistently.  This leads to quite a lot of
simplification (and, hey, probably better performance).

Add some error checking in places lacking it.

Fix some rather strange indentation in the Unicode code.

Delete some trailing whitespace.

More to come, I haven't fixed all the reference leaks yet...
