* [3.8] bpo-36389: Backport debug enhancements from master (GH-16796)Victor Stinner2019-10-151-18/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * bpo-36389: _PyObject_CheckConsistency() available in release mode (GH-16612) bpo-36389, bpo-38376: The _PyObject_CheckConsistency() function is now also available in release mode. For example, it can be used to debug a crash in the visit_decref() function of the GC. Modify the following functions to also work in release mode: * _PyDict_CheckConsistency() * _PyObject_CheckConsistency() * _PyType_CheckConsistency() * _PyUnicode_CheckConsistency() Other changes: * _PyMem_IsPtrFreed(ptr) now also returns 1 if ptr is NULL (equals to 0). * _PyBytesWriter_CheckConsistency() now returns 1 and is only used with assert(). * Reorder _PyObject_Dump() to write safe fields first, and only attempt to render repr() at the end. (cherry picked from commit 6876257eaabdb30f27ebcbd7d2557278ce2e5705) * bpo-36389: Fix _PyBytesWriter in release mode (GH-16624) Fix _PyBytesWriter API when Python is built in release mode with assertions. (cherry picked from commit 60ec6efd96d95476fe5e38c491491add04f026e5) * bpo-38070: Enhance visit_decref() debug trace (GH-16631) subtract_refs() now pass the parent object to visit_decref() which pass it to _PyObject_ASSERT(). So if the "is freed" assertion fails, the parent is used in debug trace, rather than the freed object. The parent object is more likely to contain useful information. Freed objects cannot be inspected are are displayed as "<object at xxx is freed>" with no other detail. (cherry picked from commit 4d5f94b8cd20f804c7868c5395a15aa6032f874c) * Fix also a typo in PYMEM_DEADBYTE macro comment * bpo-36389: Add newline to _PyObject_AssertFailed() (GH-16629) Add a newline between the verbose object dump and the Py_FatalError() logs for readability. (cherry picked from commit 7775349895088a7ae68cecf0c74cf817f15e2c74)
* [3.8] bpo-37206: Unrepresentable default values no longer represented as ↵Serhiy Storchaka2019-09-141-1/+1
| | | | | | | | | | None. (GH-13933) (GH-16141) In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values (like in the optional third parameter of getattr). "None" should be used if None is accepted as argument and passing None has the same effect as not passing the argument at all. (cherry picked from commit 279f44678c8b84a183f9eeb85e0b086228154497) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* Remove unneeded assignment in PyBytes_Concat() (GH-15274)Miss Islington (bot)2019-09-101-1/+0
| | | | | | The `wb.len = -1` assignment is unneeded since its introduction in 161d695fb0455ce52530d4f43a9eac4c738f64bb as `PyObject_GetBuffer` always fills it in. (cherry picked from commit afdeb189e97033b54cef44a7490d89d2013cb4e5) Co-authored-by: Sergey Fedoseev <fedoseev.sergey@gmail.com>

* bpo-22385: Support output separators in hex methods. (#13578)Gregory P. Smith2019-05-291-8/+26
| | | | | | | | | | | | | | | | | | * bpo-22385: Support output separators in hex methods. Also in binascii.hexlify aka b2a_hex. The underlying implementation behind all hex generation in CPython uses the same pystrhex.c implementation. This adds support to bytes, bytearray, and memoryview objects. The binascii module functions exist rather than being slated for deprecation because they return bytes rather than requiring an intermediate step through a str object. This change was inspired by MicroPython which supports sep in its binascii implementation (and does not yet support the .hex methods). https://bugs.python.org/issue22385

| | | | | | | The final addition (cur += step) may overflow, so use size_t for "cur". "cur" is always positive (even for negative steps), so it is safe to use size_t here. Co-Authored-By: Martin Panter <vadmium+py@gmail.com>

* bpo-35064 prefix smelly symbols that appear with COUNT_ALLOCS with _Py_ ↵Pablo Galindo2018-10-281-5/+5
| | | | | | | (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.

| | | | | | | | | (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.

This change is part of the fastcall project. The change on listsort() is related to the issue #23507.
