Barry Warsaw fa5c315afa PyErr_GivenExceptionMatches(): Check for err==NULL and exc==NULL and
return 0 (exceptions don't match).  This means that if an ImportError
is raised because exceptions.py can't be imported, the interpreter
will exit "cleanly" with an error message instead of just core
dumping.

PyErr_SetFromErrnoWithFilename(), PyErr_SetFromWindowsErrWithFilename():
Don't test on Py_UseClassExceptionsFlag.

Guido van Rossum 0b55670968 Mark discovered a bug in his patch: he didn't *use* PyExc_WindowsError
in PyErr_SetFromWindowsErrWithFilename() like he intended to... :-)

Guido van Rossum 584b16a1f3 Mark pointed out a buglet in his patch: i < _sys_nerr isn't strong
enough, it could be negative.  Add i > 0 test.  (Not i >= 0; zero isn't
a valid error number.)

Guido van Rossum 795e189d28 Patch by Mark Hammond:
* Changes to a recent patch by Chris Tismer to errors.c.  Chris' patch
always used FormatMessage() to get the error message passing the error code
from errno - but errno and FormatMessage use a different numbering scheme.
The main reason the patch looked OK was that ENOFILE==ERROR_FILE_NOT_FOUND -
but that is about the only shared error code :-).  The MS CRT docs tell you
to use _sys_errlist()/_sys_nerr.  My patch does also this, and adds a very
similar function specifically for win32 error codes.

Guido van Rossum 743007d2fe Patch by Christian Tismer for Win32, to use FormatMessage() instead of
strerror().  This improves the quality of the error messages.

Guido van Rossum 885553e8d3 Use PyThreadState_GET() macro. 1998-12-21 18:33:30 +00:00
Guido van Rossum e0e59829e0 When errno is zero, avoid calling strerror() and use "Error" for the
message.

Barry Warsaw 97d951533e PyErr_SetFromErrnoWithFilename(): New function which supports setting
an exception from errno, with a supplied filename (primarily used by
IOError and OSError).  If class exceptions are used then the exception
is instantiated with a 3-tuple: (errno, strerror, filename).  For
backwards compatibility reasons, if string exceptions are used,
filename is ignored.

PyErr_SetFromErrno(): Implement in terms of
PyErr_SetFromErrnoWithFilename().

Guido van Rossum 19b55f2d17 Fix subtle bug in cleanup code in PyErr_NormalizeException(), detected
by Marc Lemburg.  There's a path through the code where *val is NULL,
but value isn't, and value should be DECREF'ed.

Guido van Rossum 2ac650f385 New version of PyErr_NewException() that is compatible with -X option. 1997-10-03 19:50:55 +00:00
Barry Warsaw 3a74993118 PyErr_NormalizeException(): If the exception's type is a class and the
instance's class is a subclass of this, then use the instance's class
as the exception type.
1997-09-30 15:00:18 +00:00
Guido van Rossum 7617e05a9b New API PyErr_NewException(name, base, dict) to create simple new exceptions. 1997-09-16 18:43:50 +00:00
Barry Warsaw 2d8adff10a PyErr_NoMemory(): If the pre-instantiated memory exception is non-null
(PyExc_MemoryErrorInst) raise this instead of PyExc_MemoryError.  This
only happens when exception classes are enabled (e.g. when Python is
started with -X).

Barry Warsaw c0dc92af7d Three new C API functions:
- int PyErr_GivenExceptionMatches(obj1, obj2)

  Returns 1 if obj1 and obj2 are the same object, or if obj1 is an
  instance of type obj2, or of a class derived from obj2

- int PyErr_ExceptionMatches(obj)

  Higher level wrapper around PyErr_GivenExceptionMatches() which uses
  PyErr_Occurred() as obj1.  This will be the more commonly called
  function.

- void PyErr_NormalizeException(typeptr, valptr, tbptr)

  Normalizes exceptions, and places the normalized values in the
  arguments.  If type is not a class, this does nothing.  If type is a
  class, then it makes sure that value is an instance of the class by:

  1. if instance is of the type, or a class derived from type, it does
     nothing.

  2. otherwise it instantiates the class, using the value as an
     argument.  If value is None, it uses an empty arg tuple, and if
     the value is a tuple, it uses just that.

Guido van Rossum e5b4026881 Use strerror on the mac if using MSL (Jack). 1997-08-12 14:51:52 +00:00
Guido van Rossum a027efa5bf Massive changes for separate thread state management.
All per-thread globals are moved into a struct which is manipulated
separately.

Guido van Rossum 373c869a6a Quickly renamed. Also removed the long comment explaining why this is
better than the old error API.

Guido van Rossum 1ae940a587 Lots of changes, most minor (fatal() instead of abort(), use of
err_fetch/err_restore and so on).  But...
NOTE: import.c has been rewritten and all the DL stuff is now in the
new file importdl.c.
