* This reverts r63675 based on the discussion in this thread:Gregory P. Smith2008-06-091-47/+47
| | | | | | | 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.

* Give meaning to the oparg for BUILD_MAP: estimated size of the dictionary.Raymond Hettinger2007-12-181-1/+1
| | | | | | | | | | | Allows dictionaries to be pre-sized (upto 255 elements) saving time lost to re-sizes with their attendant mallocs and re-insertions. Has zero effect on small dictionaries (5 elements or fewer), a slight benefit for dicts upto 22 elements (because they had to resize once anyway), and more benefit for dicts upto 255 elements (saving multiple resizes during the build-up and reducing the number of collisions on the first insertions). Beyond 255 elements, there is no addional benefit.
* Speed-up dictionary constructor by about 10%.Raymond Hettinger2007-12-181-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | New opcode, STORE_MAP saves the compiler from awkward stack manipulations and specializes for dicts using PyDict_SetItem instead of PyObject_SetItem.

* Merge from py3k branch:Amaury Forgeot d'Arc2007-11-131-7/+12
| | | | | | | | | | | | | | | | | | | | | | Correction for issue1265 (pdb bug with "with" statement). When an unfinished generator-iterator is garbage collected, PyEval_EvalFrameEx is called with a GeneratorExit exception set. This leads to funny results if the sys.settrace function itself makes use of generators. A visible effect is that the settrace function is reset to None. Another is that the eventual "finally" block of the generator is not called. It is necessary to save/restore the exception around the call to the trace function. This happens a lot with py3k: isinstance() of an ABCMeta instance runs def __instancecheck__(cls, instance): """Override for isinstance(instance, cls).""" return any(cls.__subclasscheck__(c) for c in {instance.__class__, type(instance)}) which lets an opened generator expression each time it returns True. Backport candidate, even if the case is less frequent in 2.5.

| | | | | | | I can't think of an easy way to test this behavior. It only occurs when the file system default encoding and the interpreter default encoding are different, such that you can open the file but not decode its name.
* No more raising of string exceptions!Brett Cannon2007-01-301-13/+34
| | | | | | | The next step of PEP 352 (for 2.6) causes raising a string exception to trigger a TypeError. Trying to catch a string exception raises a DeprecationWarning. References to string exceptions has been removed from the docs since they are now just an error.

| | | | | | | 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.

* Patch 1145039.Tim Peters2006-05-261-41/+56
| | | | | | | | | | | | | | | | | | | set_exc_info(), reset_exc_info(): By exploiting the likely (who knows?) invariant that when an exception's `type` is NULL, its `value` and `traceback` are also NULL, save some cycles in heavily-executed code. This is a "a kronar saved is a kronar earned" patch: the speedup isn't reliably measurable, but it obviously does reduce the operation count in the normal (no exception raised) path through PyEval_EvalFrameEx(). The tim-exc_sanity branch tries to push this harder, but is still blowing up (at least in part due to pre-existing subtle bugs that appear to have no other visible consequences!). Not a bugfix candidate.
