* bpo-36635: Change pyport.h for Py_BUILD_CORE_MODULE define (GH-12853)Victor Stinner2019-04-1726-56/+97
| | | | | | | | | | | | | | | | | | | | Change PyAPI_FUNC(type), PyAPI_DATA(type) and PyMODINIT_FUNC macros of pyport.h when Py_BUILD_CORE_MODULE is defined. The Py_BUILD_CORE_MODULE define must be now be used to build a C extension as a dynamic library accessing Python internals: export the PyInit_xxx() function in DLL exports on Windows. Changes: * Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE now imply Py_BUILD_CORE directy in pyport.h. * ceval.c compilation now fails with an error if Py_BUILD_CORE is not defined, just to ensure that Python is build with the correct defines. * setup.py now compiles _pickle.c with Py_BUILD_CORE_MODULE define. * setup.py compiles _json.c with Py_BUILD_CORE_MODULE define, rather than Py_BUILD_CORE_BUILTIN define * PCbuild/pythoncore.vcxproj: Add Py_BUILD_CORE_BUILTIN define.
* bpo-32849: Fix is_valid_fd() on FreeBSD (GH-12852)Victor Stinner2019-04-172-15/+25
| | | | | | | Fix Python Initialization code on FreeBSD to detect properly when stdin file descriptor (fd 0) is invalid. On FreeBSD, fstat() must be used to check if stdin (fd 0) is valid. dup(0) doesn't fail if stdin is invalid in some cases.

* bpo-35755: shutil.which() uses os.confstr("CS_PATH") (GH-12858)Victor Stinner2019-04-175-18/+155
| | | | | | | | | | | | | | | | shutil.which() and distutils.spawn.find_executable() now use os.confstr("CS_PATH") if available instead of os.defpath, if the PATH environment variable is not set. Don't use os.confstr("CS_PATH") nor os.defpath if the PATH environment variable is set to an empty string to mimick Unix 'which' command behavior. Changes: * find_executable() now starts by checking for the executable in the current working directly case. Add an explicit "if not path: return None". * Add tests for PATH='' (empty string), PATH=':' and for PATHEXT.

* bpo-27860: ipaddress: fix Interface missed some attributes (GH-12836)Inada Naoki2019-04-162-71/+56
| | | | | | | IPv4Interface and IPv6Interface did not has netmask and hostmask attributes when its argument is bytes or int. This commit extracts method for constructors of Network and Interface, and ensure Interface class always provides them.
* bpo-36348: IMAP4.logout() doesn't ignore exc (GH-12411)Victor Stinner2019-04-155-13/+28
| | | | | | | | | | | | The imap.IMAP4.logout() method no longer ignores silently arbitrary exceptions. Changes: * The IMAP4.logout() method now expects a "BYE" untagged response, rather than relying on _check_bye() which raises a self.abort() exception. * IMAP4.__exit__() now does nothing if the client already logged out. * Add more debug info if test_logout() tests fail.
* bpo-36389: Cleanup gc.set_threshold() (GH-12844)Victor Stinner2019-04-151-2/+2
| | | | Don't assign generations[2].threshold to generations[2].threshold: useless operation.

* bpo-36593: Fix isinstance check for Mock objects with spec executed under ↵Xtreak2019-04-133-1/+41
| | | | | tracing (GH-12790) In Python having a trace function in effect while mock is imported causes isinstance to be wrong for MagicMocks. This is due to the usage of super() in some class methods, as this sets the __class__ attribute. To avoid this, as a workaround, alias the usage of super .

Users can use _Py_IsFinalizing or sys.is_finalizing to check if the interpreter is in the process of being finalized before calling this function to avoid unwanted termination.

* bpo-36611: Disable serialno field of debug memory allocators (#12796)Victor Stinner2019-04-123-21/+61
| | | | | | | | | | | Omit serialno field from debug hooks on Python memory allocators to reduce the memory footprint by 5%. Enable tracemalloc to get the traceback where a memory block has been allocated when a fatal memory error is logged to decide where to put a breakpoint. Compile Python with PYMEM_DEBUG_SERIALNO defined to get back the field.
* bpo-36389: Add _PyObject_CheckConsistency() function (GH-12803)Victor Stinner2019-04-126-114/+158
| | | | | | Add a new _PyObject_CheckConsistency() function which can be used to help debugging. The function is available in release mode. Add a 'check_content' parameter to _PyDict_CheckConsistency().
* bpo-36618: Add -fmax-type-align=8 flag for clang (GH-12809)Victor Stinner2019-04-123-26/+65
| | | | | | | | | | | | | | Add -fmax-type-align=8 to CFLAGS when clang compiler is detected. The pymalloc memory allocator aligns memory on 8 bytes. On x86-64, clang expects alignment on 16 bytes by default and so uses MOVAPS instruction which can lead to segmentation fault. Instruct clang that Python is limited to alignemnt on 8 bytes to use MOVUPS instruction instead: slower but don't trigger a SIGSEGV if the memory is not aligned on 16 bytes. Sadly, the flag must be expected to CFLAGS and not just CFLAGS_NODIST, since third party C extensions can have the same issue.
