* bpo-35134: Add Include/cpython/pymem.h (GH-12840)Victor Stinner2019-04-151-95/+7
| | | | Move unstable CPython API from Include/pymem.h into a new Include/cpython/pymem.h header file.
* bpo-36389: _PyObject_IsFreed() now also detects uninitialized memory (GH-12770)Victor Stinner2019-04-111-2/+0
| | | | | | | | | Replace _PyMem_IsFreed() function with _PyMem_IsPtrFreed() inline function. The function is now way more efficient, it became a simple comparison on integers, rather than a short loop. It detects also uninitialized bytes and "forbidden bytes" filled by debug hooks on memory allocators. Add unit tests on _PyObject_IsFreed().
* bpo-35081: Move Py_BUILD_CORE code to internal/mem.h (GH-10249)Victor Stinner2018-10-311-10/+0
| | | | | * Add #include "internal/mem.h" to C files using _PyMem_SetDefaultAllocator(). * Include/internal/mem.h now requires Py_BUILD_CORE to be defined.
* bpo-9263: Dump Python object on GC assertion failure (GH-10062)Victor Stinner2018-10-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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-35053: Add Include/tracemalloc.h (GH-10091)Victor Stinner2018-10-251-37/+3
| | | | | | | * Modify object.h to ensure that pymem.h is included, to get _Py_tracemalloc_config variable. * Move _PyTraceMalloc_XXX() functions to tracemalloc.h, they need PyObject type. Break circular dependency between pymem.h and object.h.
* bpo-35053: Enhance tracemalloc to trace free lists (GH-10063)Victor Stinner2018-10-251-0/+38
| | | | | | | | | | | | 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 Stinner2018-10-231-1/+3
| | | | | | | | | _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-32030: Add pymain_get_global_config() (#4735)Victor Stinner2017-12-061-4/+0
| | | | | | | | | | | | | * Py_Main() now starts by reading Py_xxx configuration variables to only work on its own private structure, and then later writes back the configuration into these variables. * Replace Py_GETENV() with pymain_get_env_var() which ignores empty variables. * Add _PyCoreConfig.dump_refs * Add _PyCoreConfig.malloc_stats * _PyObject_DebugMallocStats() is now responsible to check if debug hooks are installed. The function returns 1 if stats were written, or 0 if the hooks are disabled. Mark _PyMem_PymallocEnabled() as static.
* bpo-32030: Rework memory allocators (#4625)Victor Stinner2017-11-291-1/+9
| | | | | | | | | | | | | | | | | | | | * Fix _PyMem_SetupAllocators("debug"): always restore allocators to the defaults, rather than only caling _PyMem_SetupDebugHooks(). * Add _PyMem_SetDefaultAllocator() helper to set the "default" allocator. * Add _PyMem_GetAllocatorsName(): get the name of the allocators * main() now uses debug hooks on memory allocators if Py_DEBUG is defined, rather than calling directly malloc() * Document default memory allocators in C API documentation * _Py_InitializeCore() now fails with a fatal user error if PYTHONMALLOC value is an unknown memory allocator, instead of failing with a fatal internal error. * Add new tests on the PYTHONMALLOC environment variable * Add support.with_pymalloc() * Add the _testcapi.WITH_PYMALLOC constant and expose it as support.with_pymalloc(). * sysconfig.get_config_var('WITH_PYMALLOC') doesn't work on Windows, so replace it with support.with_pymalloc(). * pythoninfo: add _testcapi collector for pymem
* bpo-32030: Add _PyMainInterpreterConfig_ReadEnv() (#4542)Victor Stinner2017-11-241-0/+6
| | | | | | | | | | | | | | | | | | Py_GetPath() and Py_Main() now call _PyMainInterpreterConfig_ReadEnv() to share the same code to get environment variables. Changes: * Add _PyMainInterpreterConfig_ReadEnv() * Add _PyMainInterpreterConfig_Clear() * Add _PyMem_RawWcsdup() * _PyMainInterpreterConfig: rename pythonhome to home * Rename _Py_ReadMainInterpreterConfig() to _PyMainInterpreterConfig_Read() * Use _Py_INIT_USER_ERR(), instead of _Py_INIT_ERR(), for decoding errors: the user is able to fix the issue, it's not a bug in Python. Same change was made in _Py_INIT_NO_MEMORY(). * Remove _Py_GetPythonHomeWithConfig()
* bpo-32030: Split Py_Main() into subfunctions (#4399)Victor Stinner2017-11-151-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Don't use "Python runtime" anymore to parse command line options or to get environment variables: pymain_init() is now a strict separation. * Use an error message rather than "crashing" directly with Py_FatalError(). Limit the number of calls to Py_FatalError(). It prepares the code to handle errors more nicely later. * Warnings options (-W, PYTHONWARNINGS) and "XOptions" (-X) are now only added to the sys module once Python core is properly initialized. * _PyMain is now the well identified owner of some important strings like: warnings options, XOptions, and the "program name". The program name string is now properly freed at exit. pymain_free() is now responsible to free the "command" string. * Rename most methods in Modules/main.c to use a "pymain_" prefix to avoid conflits and ease debug. * Replace _Py_CommandLineDetails_INIT with memset(0) * Reorder a lot of code to fix the initialization ordering. For example, initializing standard streams now comes before parsing PYTHONWARNINGS. * Py_Main() now handles errors when adding warnings options and XOptions. * Add _PyMem_GetDefaultRawAllocator() private function. * Cleanup _PyMem_Initialize(): remove useless global constants: move them into _PyMem_Initialize(). * Call _PyRuntime_Initialize() as soon as possible: _PyRuntime_Initialize() now returns an error message on failure. * Add _PyInitError structure and following macros: * _Py_INIT_OK() * _Py_INIT_ERR(msg) * _Py_INIT_USER_ERR(msg): "user" error, don't abort() in that case * _Py_INIT_FAILED(err)

* Add PYTHONMALLOC env varVictor Stinner2016-03-141-0/+9
| | | | | | | | | | | | | Issue #26516: * Add PYTHONMALLOC environment variable to set the Python memory allocators and/or install debug hooks. * PyMem_SetupDebugHooks() can now also be used on Python compiled in release mode. * The PYTHONMALLOCSTATS environment variable can now also be used on Python compiled in release mode. It now has no effect if set to an empty string. * In debug mode, debug hooks are now also installed on Python memory allocators when Python is configured without pymalloc.

* Issue #21233: Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(),Victor Stinner2014-05-021-0/+5
| | | | | | PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) and bytearray(int) are now using ``calloc()`` instead of ``malloc()`` for large objects which is faster and use less memory (until the bytearray buffer is filled with data).

The tests that are expected to break are: test_codecencodings_cn test_codecencodings_hk test_codecencodings_jp test_codecencodings_kr test_codecencodings_tw test_codecs test_multibytecodec This merge fixes an actual test failure (test_weakref) in this branch, though, so I believe merging is the right thing to do anyway.

* Moving pymalloc along.Tim Peters2002-04-281-37/+42
| | | | | | | | | | As threatened, PyMem_{Free, FREE} also invoke the object deallocator now when pymalloc is enabled (well, it does when pymalloc isn't enabled too, but in that case "the object deallocator" is plain free()). This is maximally backward-compatible, but it leaves a bitter aftertaste. Also massive reworking of comments.
* Moving pymalloc along.Tim Peters2002-04-221-13/+9
| | | | | | | | | | | | | | | | | | + Redirect PyMem_{Del, DEL} to the object allocator's free() when pymalloc is enabled. Needed so old extensions can continue to mix PyObject_New with PyMem_DEL. + This implies that pgen needs to be able to see the PyObject_XYZ declarations too. pgenheaders.h now includes Python.h. An implication is that I expect obmalloc.o needs to get linked into pgen on non-Windows boxes. + When PYMALLOC_DEBUG is defined, *all* Py memory API functions now funnel through the debug allocator wrapper around pymalloc. This is the default in a debug build. + That caused compile.c to fail: it indirectly mixed PyMem_Malloc with raw platform free() in one place. This is verbotten.
* First stab at rationalizing the PyMem_ API. Mixing PyObject_xyz withTim Peters2002-04-121-40/+55
| | | | | | | | | | | | | | | | | | | | | | | | PyMem_{Del, DEL} doesn't work yet (compilation problems). pyport.h: _PyMem_EXTRA is gone. pmem.h: Repaired comments. PyMem_{Malloc, MALLOC} and PyMem_{Realloc, REALLOC} now make the same x-platform guarantees when asking for 0 bytes, and when passing a NULL pointer to the latter. object.c: PyMem_{Malloc, Realloc} just call their macro versions now, since the latter take care of the x-platform 0 and NULL stuff by themselves now. pypcre.c, grow_stack(): So sue me. On two lines, this called PyMem_RESIZE to grow a "const" area. It's not legit to realloc a const area, so the compiler warned given the new expansion of PyMem_RESIZE. It would have gotten the same warning before if it had used PyMem_Resize() instead; the older macro version, but not the function version, silently cast away the constness. IMO that was a wrong thing to do, and the docs say the macro versions of PyMem_xyz are deprecated anyway. If somebody else is resizing const areas with the macro spelling, they'll get a warning when they recompile now too.

| | | | | | | | | | | | | This displays stats about the # of arenas, pools, blocks and bytes, to stderr, both used and reserved but unused. CAUTION: Because PYMALLOC_DEBUG is on, the debug malloc routine adds 16 bytes to each request. This makes each block appear two size classes higher than it would be if PYMALLOC_DEBUG weren't on. So far, playing with this confirms the obvious: there's a lot of activity in the "small dict" size class, but nothing in the core makes any use of the 8-byte or 16-byte classes.

* Give Python a debug-mode pymalloc, much as sketched on Python-Dev.Tim Peters2002-03-231-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug allocator. This can be done independent of build type (release or debug). A debug build automatically defines PYMALLOC_DEBUG when pymalloc is enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc isn't enabled. Two debugging entry points defined only under PYMALLOC_DEBUG: + _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb) to sanity-check a memory block obtained from pymalloc. It sprays info to stderr (see next) and dies via Py_FatalError if the block is detectably damaged. + _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info about a debug memory block to stderr. A tiny start at implementing "API family" checks isn't good for anything yet. _PyMalloc_DebugRealloc() has been optimized to do little when the new size is <= old size. However, if the new size is larger, it really can't call the underlying realloc() routine without either violating its contract, or knowing something non-trivial about how the underlying realloc() works. A memcpy is always done in this case. This was a disaster for (and only) one of the std tests: test_bufio creates single text file lines up to a million characters long. On Windows, fileobject.c's get_line() uses the horridly funky getline_via_fgets(), which keeps growing and growing a string object hoping to find a newline. It grew the string object 1000 bytes each time, so for a million-character string it took approximately forever (I gave up after a few minutes). So, also: fileobject.c, getline_via_fgets(): When a single line is outrageously long, grow the string object at a mildly exponential rate, instead of just 1000 bytes at a time. That's enough so that a debug-build test_bufio finishes in about 5 seconds on my Win98SE box. I'm curious to try this on Win2K, because it has very different memory behavior than Win9X, and test_bufio always took a factor of 10 longer to complete on Win2K. It *could* be that the endless reallocs were simply killing it on Win2K even in the release build.
* Arrange to export the _PyMalloc_{Malloc, Realloc, Free} entry points. OnTim Peters2002-03-201-3/+3
| | | | | | | | | | | | | Windows some modules are considered (by me, and I don't care what anyone else thinks about this <wink>) to be part of "the core" despite that they happen to be compiled into separate DLLs (the "to DLL or not to DLL?" question on Windows is nearly arbitrary). Making the pymalloc entry points available to them allows the Windows build to complete without incident when WITH_PYMALLOC is #define'd. Note that this isn't unprecedented. Other "private API" functions we export include _PySequence_IterSearch, _PyEval_SliceIndex, _PyCodec_Lookup, _Py_ZeroStruct, _Py_TrueStruct, _PyLong_New and _PyModule_Clear.
