Victor Stinner 52aee85613 Issue #22156: simplify _tracemalloc.c, use an int for the MAX_NFRAME constant 2014-08-16 15:44:02 +02:00
Victor Stinner 706768c687 Issue #22156: Fix some "comparison between signed and unsigned integers"
compiler warnings in the Modules/ subdirectory.

Victor Stinner d8f0d922d5 Issue #21233: Rename the C structure "PyMemAllocator" to "PyMemAllocatorEx" to
make sure that the code using it will be adapted for the new "calloc" field
(instead of crashing).

Victor Stinner aa0e7afa43 Issue #21639: Fix a division by zero in tracemalloc on calloc(0, 0). The
regression was introduced recently with the introduction of the new "calloc"
functions (PyMem_RawCalloc, PyMem_Calloc, PyObject_Calloc).

Add also a unit test to check for the non-regression.

Victor Stinner 45e8e2f218 Issue #21490: Add new C macros: Py_ABS() and Py_STRINGIFY()
Keep _Py_STRINGIZE() in PC/pyconfig.h to not introduce a dependency between
pyconfig.h and pymacros.h.

Victor Stinner db067af12a Issue #21233: Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(),
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).

Victor Stinner dd382ef8ec Issue #20354: Fix alignment issue in the tracemalloc module on 64-bit
platforms. Bug seen on 64-bit Linux when using "make profile-opt".

Only align the "frame_t" structure on 32-bit when Visual Studio is used. Before
the alignment to 32-bit was applied to the whole file any compiler supporting
"#pragma pack(4)" which includes GCC.

Victor Stinner 711e27cd50 tracemalloc: fix usage of strtol(), value can be LONG_MIN or LONG_MAX on ERANGE 2013-12-16 23:06:19 +01:00
Victor Stinner 4d8c29cd57 tracemalloc: only use unsigned types to compute hash
Commit to simplify the backport to python 2.7 and to make the code more
consistent.

Victor Stinner 590cebe391 Issue #19787: PyThread_set_key_value() now always set the value
In Python 3.3, PyThread_set_key_value() did nothing if the key already exists
(if the current value is a non-NULL pointer).

When _PyGILState_NoteThreadState() is called twice on the same thread with a
different Python thread state, it still keeps the old Python thread state to
keep the old behaviour. Replacing the Python thread state with the new state
introduces new bugs: see issues #10915 and #15751.

test_capi is failing and the fix is not trivial, I prefer to revert

Victor Stinner cd0cb8ccd3 Close #19787: PyThread_set_key_value() now always set the value. In Python 3.3,
the function did nothing if the key already exists (if the current value is a
non-NULL pointer).

_testcapi.run_in_subinterp() now correctly sets the new Python thread state of
the current thread when a subinterpreter is created.

Victor Stinner 88c29877c7 Close #19741: tracemalloc_realloc() does not release the table lock anymore
between tracemalloc_remove_trace() and tracemalloc_add_trace() to reduce the
risk of race condition.

tracemalloc_add_trace() cannot fail anymore in tracemalloc_realloc() when
tracemalloc_realloc() resizes a memory block.

Victor Stinner 1511680b79 Close #19757: Cleanup tracemalloc, move
PyGILState_Ensure()/PyGILState_Release() calls to the raw wrappers to simplify
the code.

Rename also tracemalloc_log_alloc/log_free() to
tracemalloc_add_trace/remove_trace().

Victor Stinner be0708f066 Closes #19831: Stop tracemalloc later at Python shutdown to be able to use
tracemalloc in objects destructor

Replace atexit handler with an harcoded C function _PyTraceMalloc_Fini().

Victor Stinner f28ce60441 Closes #19786: tracemalloc, remove the arbitrary limit of 100 frames
The limit is now 178,956,969 on 64 bit (it is greater on 32 bit because
structures are smaller).

Use int instead of Py_ssize_t to store the number of frames to have smaller
traceback_t objects.

Victor Stinner 3c0481d426 Close #19798: replace "maximum" term with "peak" in get_traced_memory()
documentation. Use also the term "current" for the current size.
