* Remove an unused variable after bpo-35444. (GH-11117)Serhiy Storchaka2018-12-111-1/+0
|
* bpo-35444: Unify and optimize the helper for getting a builtin object. ↵Serhiy Storchaka2018-12-111-17/+0
| | | | | | | | (GH-11047) This speeds up pickling of some iterators. This fixes also error handling in pickling methods when fail to look up builtin "getattr".
* bpo-9263: Fix _PyObject_Dump() for freed object (#10661)Victor Stinner2018-11-221-0/+5
| | | | | | | If _PyObject_Dump() detects that the object is freed, don't try to dump it (exit immediately). Enhance also _PyObject_IsFreed(): it now detects if the pointer itself looks like freed memory.
* bpo-35059: Enhance _PyObject_AssertFailed() (GH-10642)Victor Stinner2018-11-211-10/+14
| | | | | | Enhance _PyObject_AssertFailed() * Exchange 'expr' and 'msg' parameters * 'expr' and 'func' arguments can now be NULL
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-121-1/+1
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-33462: Add __reversed__ to dict and dict views (GH-6827)Rémi Lapeyre2018-11-061-0/+9

* bpo-35081: Add _PyThreadState_GET() internal macro (GH-10266)Victor Stinner2018-11-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | If Py_BUILD_CORE is defined, the PyThreadState_GET() macro access _PyRuntime which comes from the internal pycore_state.h header. Public headers must not require internal headers. Move PyThreadState_GET() and _PyInterpreterState_GET_UNSAFE() from Include/pystate.h to Include/internal/pycore_state.h, and rename PyThreadState_GET() to _PyThreadState_GET() there. The PyThreadState_GET() macro of pystate.h is now redefined when pycore_state.h is included, to use the fast _PyThreadState_GET(). Changes: * Add _PyThreadState_GET() macro * Replace "PyThreadState_GET()->interp" with _PyInterpreterState_GET_UNSAFE() * Replace PyThreadState_GET() with _PyThreadState_GET() in internal C files (compiled with Py_BUILD_CORE defined), but keep PyThreadState_GET() in the public header files. * _testcapimodule.c: replace PyThreadState_GET() with PyThreadState_Get(); the module is not compiled with Py_BUILD_CORE defined. * pycore_state.h now requires Py_BUILD_CORE to be defined.
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-2/+2
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
* bpo-35059: Convert _Py_Dealloc() to static inline function (GH-10223)Victor Stinner2018-10-301-15/+9
| | | | | Convert _Py_Dealloc() macro into a static inline function. Moreover, it is now also defined as a static inline function if Py_TRACE_REFS is defined.
* bpo-35064 prefix smelly symbols that appear with COUNT_ALLOCS with _Py_ ↵Pablo Galindo2018-10-281-11/+11
| | | | | | | (GH-10152) Configuring python with ./configure --with-pydebug CFLAGS="-D COUNT_ALLOCS -O0" makes "make smelly" fail as some symbols were being exported without the "Py_" or "_Py" prefixes.
* bpo-9263: Use _PyObject_ASSERT() in object.c (GH-10110)Victor Stinner2018-10-261-18/+22
| | | | Replace assert() with _PyObject_ASSERT() in Objects/object.c to dump the faulty object on assertion failure to ease debugging.
* bpo-9263: _Py_NegativeRefcount() use _PyObject_AssertFailed() (GH-10109)Victor Stinner2018-10-261-8/+5
| | | | _Py_NegativeRefcount() now uses _PyObject_AssertFailed() to dump the object to help debugging.
* bpo-9263: Dump Python object on GC assertion failure (GH-10062)Victor Stinner2018-10-251-0/+52
| | | | | | | | | | | | | | | | | | | | | | | Changes: * Add _PyObject_AssertFailed() function. * Add _PyObject_ASSERT() and _PyObject_ASSERT_WITH_MSG() macros. * gc_decref(): replace assert() with _PyObject_ASSERT_WITH_MSG() to dump the faulty object if the assertion fails. _PyObject_AssertFailed() calls: * _PyMem_DumpTraceback(): try to log the traceback where the object memory has been allocated if tracemalloc is enabled. * _PyObject_Dump(): log repr(obj). * Py_FatalError(): log the current Python traceback. _PyObject_AssertFailed() uses _PyObject_IsFreed() heuristic to check if the object memory has been freed by a debug hook on Python memory allocators. Initial patch written by David Malcolm. Co-Authored-By: David Malcolm <dmalcolm@redhat.com>
* bpo-35059: Add Py_STATIC_INLINE() macro (GH-10093)Victor Stinner2018-10-251-2/+2
| | | | | | | | | * Add Py_STATIC_INLINE() macro to declare a "static inline" function. If the compiler supports it, try to always inline the function even if no optimization level was specified. * Modify pydtrace.h to use Py_STATIC_INLINE() when WITH_DTRACE is not defined. * Add an unit test on Py_DECREF() to make sure that _Py_NegativeRefcount() reports the correct filename.
* bpo-35053: Enhance tracemalloc to trace free lists (GH-10063)Victor Stinner2018-10-251-0/+3
| | | | | | | | | | | | tracemalloc now tries to update the traceback when an object is reused from a "free list" (optimization for faster object creation, used by the builtin list type for example). Changes: * Add _PyTraceMalloc_NewReference() function which tries to update the Python traceback of a Python object. * _Py_NewReference() now calls _PyTraceMalloc_NewReference(). * Add an unit test.
* bpo-9263: _PyObject_Dump() detects freed memory (GH-10061)Victor Stinner2018-10-231-23/+55
| | | | | | | | | _PyObject_Dump() now uses an heuristic to check if the object memory has been freed: log "<freed object>" in that case. The heuristic rely on the debug hooks on Python memory allocators which fills the memory with DEADBYTE (0xDB) when memory is deallocated. Use PYTHONMALLOC=debug to always enable these debug hooks.
* bpo-34910: Ensure that PyObject_Print() always returns -1 on error. (GH-9733)Zackery Spytz2018-10-061-2/+3
|
* closes bpo-34646: Remove PyAPI_* macros from declarations. (GH-9218)Benjamin Peterson2018-09-121-1/+1
|
* bpo-34301: Add _PyInterpreterState_Get() helper function (GH-8592)Victor Stinner2018-08-031-1/+1
| | | | sys_setcheckinterval() now uses a local variable to parse arguments, before writing into interp->check_interval.
* bpo-33597: Reduce PyGC_Head size (GH-7043)INADA Naoki2018-07-101-6/+7
|
* Replace _PyGC_REFS macros with higher level macros (GH-6852)INADA Naoki2018-05-171-5/+3
| | | | Only gcmodule.c uses _PyGC_REFS* macros now. This makes easy to read GC code.
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-2/+2
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
* closes bpo-32898: Fix debug build crash with COUNT_ALLOCS (GH-5800)Eddie Elizondo2018-02-221-1/+2
|
* bpo-32571: Fix reading uninitialized memory (GH-5332)INADA Naoki2018-01-261-0/+5
| | | Reported by Coverity Scan.
* bpo-32571: Avoid raising unneeded AttributeError and silencing it in C code ↵Serhiy Storchaka2018-01-251-27/+49
| | | | | (GH-5222) Add two new private APIs: _PyObject_LookupAttr() and _PyObject_LookupAttrId()
* bpo-32436: Implement PEP 567 (#5027)Yury Selivanov2018-01-231-0/+1
|
* bpo-32544: Speed up hasattr() and getattr() (GH-5173)INADA Naoki2018-01-161-6/+50
| | | | | AttributeError was raised always when attribute is not found. This commit skip raising AttributeError when `tp_getattro` is `PyObject_GenericGetAttr`. It makes hasattr() and getattr() about 4x faster when attribute is not found.
* bpo-32137: The repr of deeply nested dict now raises a RecursionError (#4570)Serhiy Storchaka2017-12-031-0/+5
| | | | | instead of crashing due to a stack overflow. This perhaps will fix similar problems in other extension types.
* bpo-32030: Add more options to _PyCoreConfig (#4485)Victor Stinner2017-11-211-20/+3
| | | | | | Py_Main() now handles two more -X options: * -X showrefcount: new _PyCoreConfig.show_ref_count field * -X showalloccount: new _PyCoreConfig.show_alloc_count field
* bpo-30860: Fix a refleak. (#3567)Eric Snow2017-09-141-12/+15
| | | | | Resolves bpo-31420. (This was accidentally reverted when in #3565.)
* bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)Eric Snow2017-09-141-15/+12
| | | PR #1638, for bpo-28411, causes problems in some (very) edge cases. Until that gets sorted out, we're reverting the merge. PR #3506, a fix on top of #1638, is also getting reverted.
* bpo-30860: Fix a refleak. (#3506)Eric Snow2017-09-121-12/+15

* Issue #26110: Add LOAD_METHOD/CALL_METHOD opcodes.Yury Selivanov2016-12-141-1/+89
| | | | | | | Special thanks to INADA Naoki for pushing the patch through the last mile, Serhiy Storchaka for reviewing the code, and to Victor Stinner for suggesting the idea (originally implemented in the PyPy project).
* Use _PyObject_CallNoArg()Victor Stinner2016-12-061-2/+2

* Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-2/+2
| | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-2/+2
| | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.
