* Patch by Tim Peters:Guido van Rossum1999-06-222-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new builtin exception, UnboundLocalError, raised when ceval.c tries to retrieve or delete a local name that isn't bound to a value. Currently raises NameError, which makes this behavior a FAQ since the same error is raised for "missing" global names too: when the user has a global of the same name as the unbound local, NameError makes no sense to them. Even in the absence of shadowing, knowing whether a bogus name is local or global is a real aid to quick understanding. Example: D:\src\PCbuild>type local.py x = 42 def f(): print x x = 13 return x f() D:\src\PCbuild>python local.py Traceback (innermost last): File "local.py", line 8, in ? f() File "local.py", line 4, in f print x UnboundLocalError: x D:\src\PCbuild> Note that UnboundLocalError is a subclass of NameError, for compatibility with existing class-exception code that may be trying to catch this as a NameError. Unfortunately, I see no way to make this wholly compatible with -X (see comments in bltinmodule.c): under -X, [UnboundLocalError is an alias for NameError --GvR]. [The ceval.c patch differs slightly from the second version that Tim submitted; I decided not to raise UnboundLocalError for DELETE_NAME, only for DELETE_LOCAL. DELETE_NAME is only generated at the module level, and since at that level a NameError is raised for referencing an undefined name, it should also be raised for deleting one.]
* CRITICAL PATCH!Guido van Rossum1999-06-181-5/+23
| | | | | | | | | | | | | | We occasionally received reports from people getting "invalid tstate" crashes (this is a fatal error in PyThreadState_Delete()). Finally several people were able to reproduce it reliably and Tim Peters discovered that there is a race condition when multiple threads are calling this function without holding the global interpreter lock (the function may be called without holding that). Solved the race condition by adding a lock around the mutating uses of interp->tstate_head. Tim and Jonathan Giddy have run tests that make it likely that this fixes the crashes -- although Tim hasn't heard from the person who reported the original problem.

* Patch by Jim Fulton (code style tweaked a bit) to supportGuido van Rossum1999-06-161-17/+94
| | | | | | | | | | | | | | | | ExtensionClasses in isinstance() and issubclass(). - abstract instance and class protocols are used *only* in those cases that would generate errors before the patch. That is, there's no penalty for the normal case. - instance protocol: an object smells like an instance if it has a __class__ attribute that smells like a class. - class protocol: an object smells like a class if it has a __bases__ attribute that is a tuple with elements that smell like classes (although not all elements may actually get sniffed ;).

| | | | | | | | | The following patches (relative to 1.5.2b1) enable Python dynamic loading to work on NetBSD platforms that use ELF (presnetly mips and alpha systems). They automaticly determine wether the system is ELF or a.out rather than using astatic list of platforms so that when other NetBSD platforms move to ELF, python will continue to work without change.
