* Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as toAntoine Pitrou2008-08-261-1/+0
| | | | | | | | | | match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__ mechanism. In the process, fix a bug where isinstance() and issubclass(), when given a tuple of classes as second argument, were looking up __instancecheck__ / __subclasscheck__ on the tuple rather than on each type object. Reviewed by Benjamin Peterson and Raymond Hettinger.

| | | | | | | http://mail.python.org/pipermail/python-dev/2008-June/079988.html Python 2.6 should stick with PyString_* in its codebase. The PyBytes_* names in the spirit of 3.0 are available via a #define only. See the email thread.

| | | | | | | | | 'warnings' code in places where it was previously not possible (e.g., the parser). It could also potentially lead to a speed-up in interpreter start-up if the C version of the code (_warnings) is imported over the use of the Python version in key places. Closes issue #1631171.

* Forward-port of r52136,52138: a review of overflow-detecting code.Armin Rigo2006-10-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | * unified the way intobject, longobject and mystrtoul handle values around -sys.maxint-1. * in general, trying to entierely avoid overflows in any computation involving signed ints or longs is extremely involved. Fixed a few simple cases where a compiler might be too clever (but that's all guesswork). * more overflow checks against bad data in marshal.c. * 2.5 specific: fixed a number of places that were still confusing int and Py_ssize_t. Some of them could potentially have caused "real-world" breakage. * list.pop(x): fixing overflow issues on x was messy. I just reverted to PyArg_ParseTuple("n"), which does the right thing. (An obscure test was trying to give a Decimal to list.pop()... doesn't make sense any more IMHO) * trying to write a few tests...

* Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().Neal Norwitz2006-07-301-2/+13
| | | | | | This provides the proper warning for struct.pack(). PyErr_Warn() is now deprecated in favor of PyErr_WarnEx(). As mentioned by Tim Peters on python-dev.

| | | | | | | | | | | exceptions that can't be raised any further, because (for instance) they occur in __del__ methods. The coroutine tests in test_generators was triggering this leak. Remove the leakers' testcase, and add a simpler testcase that explicitly tests this leak to test_generators. test_generators now no longer leaks at all, on my machine. This fix may also solve other leaks, but my full refleakhunting run is still busy, so who knows?
* spread the extern "C" { } magic pixie dust around. Python itself builds nowAnthony Baxter2006-04-131-0/+10

| | | | | | | | | added message attribute compared to the previous version of Exception. It is also a new-style class, making all exceptions now new-style. KeyboardInterrupt and SystemExit inherit from BaseException directly. String exceptions now raise DeprecationWarning. Applies patch 1104669, and closes bugs 1012952 and 518846.
* Updates to the with-statement:Guido van Rossum2006-02-281-0/+1
| | | | | | | | | | | | | | | | - New semantics for __exit__() -- it must re-raise the exception if type is not None; the with-statement itself doesn't do this. (See the updated PEP for motivation.) - Added context managers to: - file - thread.LockType - threading.{Lock,RLock,Condition,Semaphore,BoundedSemaphore} - decimal.Context - Added contextlib.py, which defines @contextmanager, nested(), closing(). - Unit tests all around; bot no docs yet.
* PyErr_ProgramText(): Grrrrrr.Tim Peters2006-02-271-1/+1
| | | | | | | | | | | In a Windows debug build, trying to open a file using an empty string as the name causes assertion death inside MS's C runtime code. We probably need to worm around that in many places. I'm worming around it here to stop the new test_with.py from assert-dying in the Windows debug build (it calls compile() with an empty string for "the file name", which indirectly leads to C-level code in Python trying to fopen("", "r")).

* Fix [ 771097 ] frozen programs fail due to implicit import of "warnings".Mark Hammond2003-07-151-3/+4
| | | | | | If the initial import of warnings fails, clear the error. When the module is actually needed, if the original import failed, see if it has managed to find its way to sys.modules yet and if so, remember it.
* PyErr_NormalizeException(): in the type==NULL test, we should simplyGuido van Rossum2003-04-101-3/+2
| | | | | | | | return. Setting an exception can mess with the exception state, and continuing is definitely wrong (since type is dereferenced later on). Some code that calls this seems to be prepared for a NULL exception type, so let's be safe rather than sorry and simply assume there's nothing to normalize in this case.

| | | | | | | | | | PyErr_SetExcFromWindowsErr(), PyErr_SetExcFromWindowsErrWithFilename(). Similar to PyErr_SetFromWindowsErrWithFilename() and PyErr_SetFromWindowsErr(), but they allow to specify the exception type to raise. Available on Windows. See SF patch #576458.

* Mass checkin of universal newline support.Jack Jansen2002-04-141-2/+2
| | | | | | | | Highlights: import and friends will understand any of \r, \n and \r\n as end of line. Python file input will do the same if you use mode 'U'. Everything can be disabled by configuring with --without-universal-newlines. See PEP278 for details.

* Patch #50002: Display line information for bad \x escapes:Martin v. Löwis2002-03-031-1/+23
| | | | | | - recognize "SyntaxError"s by the print_file_and_line attribute. - add the syntaxerror attributes to all exceptions in compile.c. Fixes #221791
* SF bug [#467265] Compile errors on SuSe Linux on IBM/s390.Tim Peters2001-10-021-1/+1
| | | | | | | Unknown whether this fixes it. - stringobject.c, PyString_FromFormatV: don't assume that va_list is of a type that can be copied via an initializer. - errors.c, PyErr_Format: add a va_end() to balance the va_start().
* PyErr_NormalizeException()Jeremy Hylton2001-09-261-1/+12
| | | | | | | | | | | | | | | | | | If a new exception occurs while an exception instance is being created, try harder to make sure there is a traceback. If the original exception had a traceback associated with it and the new exception does not, keep the old exception. Of course, callers to PyErr_NormalizeException() must still be prepared to have tb set to NULL. XXX This isn't an ideal solution, but it's better than no traceback at all. It occurs if, for example, the exception occurs when the call to the constructor fails before any Python code is executed. Guido suggests that it there is Python code that was about to be executed -- but wasn't, say, because it was called with the wrong number of arguments -- then we should point at the first line of the code object anyway.
* PyErr_Format(): Factor out most of this code intoBarry Warsaw2001-08-241-114/+1
| | | | | PyString_FromFormat() since it's much more generally useful than just for exceptions.
