| | | | | | | 00147 # Add a sys._debugmallocstats() function Based on patch 202 from RHEL 5's python.spec, with updates from rhbz#737198 Sent upstream as http://bugs.python.org/issue14785
* [2.7] bpo-32137: The repr of deeply nested dict now raises a RuntimeError ↵Serhiy Storchaka2018-02-021-3/+0
| | | | | | | | | (GH-4570) (#5493) instead of crashing due to a stack overflow. This perhaps will fix similar problems in other extension types. (cherry picked from commit 1fb72d2ad243c965d4432b4e93884064001a2607)

This can reduce the size of collections and therefore the garbage collection overhead on long-running programs, depending on their particular use of datatypes.

| | | | | | | | | | Python code; but it is possible from C. object.__str__ had the issue of not expecting a type to doing something within it's tp_str implementation that could trigger an infinite recursion, but it could in C code.. Both found thanks to BaseException and how it handles its repr. Closes issue #1686386. Thanks to Thomas Herve for taking an initial stab at coming up with a solution.

* Improve extended slicing support in builtin types and classes. Specifically:Thomas Wouters2007-08-281-0/+6
| | | | | | | | | | | | | | | | | | | | - Specialcase extended slices that amount to a shallow copy the same way as is done for simple slices, in the tuple, string and unicode case. - Specialcase step-1 extended slices to optimize the common case for all involved types. - For lists, allow extended slice assignment of differing lengths as long as the step is 1. (Previously, 'l[:2:1] = []' failed even though 'l[:2] = []' and 'l[:2:None] = []' do not.) - Implement extended slicing for buffer, array, structseq, mmap and UserString.UserString. - Implement slice-object support (but not non-step-1 slice assignment) for UserString.MutableString. - Add tests for all new functionality.
* PEP 3123: Provide forward compatibility with Python 3.0, while keepingMartin v. Löwis2007-07-211-40/+38
| | | | | backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and PyVarObject_HEAD_INIT.
* Variation of patch # 1624059 to speed up checking if an object is a subclassNeal Norwitz2007-02-251-1/+1
| | | | | | | | | | | | | | | | | | of some of the common builtin types. Use a bit in tp_flags for each common builtin type. Check the bit to determine if any instance is a subclass of these common types. The check avoids a function call and O(n) search of the base classes. The check is done in the various Py*_Check macros rather than calling PyType_IsSubtype(). All the bits are set in tp_flags when the type is declared in the Objects/*object.c files because PyType_Ready() is not called for all the types. Should PyType_Ready() be called for all types? If so and the change is made, the changes to the Objects/*object.c files can be reverted (remove setting the tp_flags). Objects/typeobject.c would also have to be modified to add conditions for Py*_CheckExact() in addition to each the PyType_IsSubtype check.

* Patch #1538606, Patch to fix __index__() clipping.Neal Norwitz2006-08-121-5/+2
| | | | | | | 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.
* Use Py_VISIT in all tp_traverse methods, instead of traversing manually orThomas Wouters2006-04-151-13/+5
| | | | | | | | using a custom, nearly-identical macro. This probably changes how some of these functions are compiled, which may result in fractionally slower (or faster) execution. Considering the nature of traversal, visiting much of the address space in unpredictable patterns, I'd argue the code readability and maintainability is well worth it ;P

* More low-hanging fruit. Still need to re-arrange some code (or find a betterAnthony Baxter2006-04-111-5/+5

* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-1/+1
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.
