* Conversion of exceptions over from faked-up classes to new-style C types.Richard Jones2006-05-271-2/+66
|
* needforspeed: backed out the Py_LOCAL-isation of ceval; the massive in-Fredrik Lundh2006-05-271-8/+15
| | | | | lining killed performance on certain Intel boxes, and the "aggressive" macro itself gives most of the benefits on others.
* Patch 1145039.Tim Peters2006-05-261-0/+9
| | | | | | | | | | | | | | | | | | | 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.

* needforspeed: added PY_LOCAL_AGGRESSIVE macro to enable "aggressive"Fredrik Lundh2006-05-261-0/+8
| | | | LOCAL inlining; also added some missing whitespace
* use Py_LOCAL also for string and unicode objectsFredrik Lundh2006-05-261-2/+7
|
* needforspeed: added Py_LOCAL macro, based on the LOCAL macro usedFredrik Lundh2006-05-261-0/+17
| | | | | for SRE and others. applied Py_LOCAL to relevant portion of ceval, which gives a 1-2% speedup on my machine. ymmv.
* needforspeed: partition implementation, part two.Fredrik Lundh2006-05-261-0/+9
| | | | feel free to improve the documentation and the docstrings.
* A new table to help string->integer conversion was added yesterday toTim Peters2006-05-251-0/+1
| | | | | | both mystrtoul.c and longobject.c. Share the table instead. Also cut its size by 64 entries (they had been used for an inscrutable trick originally, but the code no longer tries to use that trick).

* Added a new macro, Py_IS_FINITE(X). On windows there is an intrinsic for ↵Kristján Valur Jónsson2006-05-251-0/+9

* Merge from rjones-funccall branch.Richard Jones2006-05-231-0/+1
| | | | | | Applied patch zombie-frames-2.diff from sf patch 876206 with updates for Python 2.5 and also modified to retain the free_list to avoid the 67% slow-down in pybench recursion test. 5% speed up in function call pybench.

* Patch #1492356: Port to Windows CE (patch set 1).Martin v. Löwis2006-05-222-0/+14
|
* - Add new Warning class, ImportWarningThomas Wouters2006-04-271-0/+1
| | | | | | | | | | | | | | - Warn-raise ImportWarning when importing would have picked up a directory as package, if only it'd had an __init__.py. This swaps two tests (for case-ness and __init__-ness), but case-test is not really more expensive, and it's not in a speed-critical section. - Test for the new warning by importing a common non-package directory on sys.path: site-packages - In regrtest.py, silence warnings generated by the build-environment because Modules/ (which is added to sys.path for Setup-created modules) has 'zlib' and '_ctypes' directories without __init__.py's.

* Define MAXPATHLEN to be at least PATH_MAX, if that's defined. Python usesThomas Wouters2006-04-251-0/+4
| | | | | | | | | MAXPATHLEN-sized buffers for various output-buffers (like to realpath()), and that's correct on BSD platforms, but not Linux (which uses PATH_MAX, and does not define MAXPATHLEN.) Cursory googling suggests Linux is following a newer standard than BSD, but in cases like this, who knows. Using the greater of PATH_MAX and 1024 as a fallback for MAXPATHLEN seems to be the most portable solution.

* frame_traverse(): Use the standard Py_VISIT macro.Tim Peters2006-04-151-7/+7
| | | | | | | Py_VISIT: cast the `op` argument to PyObject* when calling `visit()`. Else the caller has to pay too much attention to this silly detail (e.g., frame_traverse needs to traverse `struct _frame *` and `PyCodeObject *` pointers too).

As note in Python.asdl says, we might want to rethink how attributes are handled. Perhaps they should be the same as other fields, with the primary difference being how they are defined for all types within a sum. Also fix asdl_c so that constructors with int fields don't fail when passed a zero value.

* Years in the making.Tim Peters2006-03-262-16/+9
| | | | | | | | | | | | | | | | | | | | | | | | objimpl.h, pymem.h: Stop mapping PyMem_{Del, DEL} and PyMem_{Free, FREE} to PyObject_{Free, FREE} in a release build. They're aliases for the system free() now. _subprocess.c/sp_handle_dealloc(): Since the memory was originally obtained via PyObject_NEW, it must be released via PyObject_FREE (or _DEL). pythonrun.c, tokenizer.c, parsermodule.c: I lost count of the number of PyObject vs PyMem mismatches in these -- it's like the specific function called at each site was picked at random, sometimes even with memory obtained via PyMem getting released via PyObject. Changed most to use PyObject uniformly, since the blobs allocated are predictably small in most cases, and obmalloc is generally faster than system mallocs then. If extension modules in real life prove as sloppy as Python's front end, we'll have to revert the objimpl.h + pymem.h part of this patch. Note that no problems will show up in a debug build (all calls still go thru obmalloc then). Problems will show up only in a release build, most likely segfaults.
