* bpo-38282: Rewrite getsockaddrarg() helper function (GH-16698)Victor Stinner2019-10-102-39/+25
| | | | | | | | Rewrite getsockaddrarg() helper function of socketmodule.c (_socket module) to prevent a false alarm when compiling codde using GCC with _FORTIFY_SOURCE=2. Pass a pointer of the sock_addr_t union, rather than passing a pointer to a sockaddr structure. Add "struct sockaddr_tipc tipc;" to the sock_addr_t union.

| | | | | | | PR #4906 changed the typing.Generic class hierarchy, leaving an outdated comment in the library reference. User-defined Generic ABCs now must get a abc.ABCMeta metaclass from something other than typing.Generic inheritance.

* bpo-38379: don't claim objects are collected when they aren't (#16658)Tim Peters2019-10-093-6/+75
| | | | | | * bpo-38379: when a finalizer resurrects an object, nothing is actually collected in this run of gc. Change the stats to relect that truth.

* bpo-37531: regrtest ignores output on timeout (GH-16659)Victor Stinner2019-10-083-28/+42
| | | | | | | | | | | bpo-37531, bpo-38207: On timeout, regrtest no longer attempts to call `popen.communicate() again: it can hang until all child processes using stdout and stderr pipes completes. Kill the worker process and ignores its output. Reenable test_regrtest.test_multiprocessing_timeout(). bpo-37531: Change also the faulthandler timeout of the main process from 1 minute to 5 minutes, for Python slowest buildbots.

* bpo-38395: Fix ownership in weakref.proxy methods (GH-16632)Pablo Galindo2019-10-083-31/+111
| | | | | | | | | | | | | The implementation of weakref.proxy's methods call back into the Python API using a borrowed references of the weakly referenced object (acquired via PyWeakref_GET_OBJECT). This API call may delete the last reference to the object (either directly or via GC), leaving a dangling pointer, which can be subsequently dereferenced. To fix this, claim a temporary ownership of the referenced object when calling the appropriate method. Some functions because at the moment they do not need to access the borrowed referent, but to protect against future changes to these functions, ownership need to be fixed in all potentially affected methods.
* bpo-38118: Ignore Valgrind false alarm in PyUnicode_Decode() (GH-16651)Victor Stinner2019-10-082-0/+13
| | | | | | | Valgrind emits "Conditional jump or move depends on uninitialised value(s)" false alarms on GCC builtin strcmp() function. The GCC code is correct. Valgrind bug: https://bugs.kde.org/show_bug.cgi?id=264936
* bpo-38407: Add docstrings for typing.SupportsXXX classes. (GH-16644)Serhiy Storchaka2019-10-081-0/+7

| | | | | | | stderr. (GH-16583) It now escapes them with a backslash, as the regular Python interpreter. Added the "errors" field to the standard streams.
* bpo-38371: Tkinter: deprecate the split() method. (GH-16584)Serhiy Storchaka2019-10-084-4/+23

* bpo-38070: Enhance visit_decref() debug trace (GH-16631)Victor Stinner2019-10-081-4/+5
| | | | | | | | 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.
* bpo-38400 Don't check for NULL linked list pointers in _PyObject_IsFreed ↵Pablo Galindo2019-10-081-1/+4
| | | | | | | | | (GH-16630) Some objects like Py_None are not initialized with conventional means that prepare the circular linked list pointers, leaving them unlinked from the rest of the objects. For those objects, NULL pointers does not mean that they are freed, so we need to skip the check in those cases.
* bpo-38392: PyObject_GC_Track() validates object in debug mode (GH-16615)Victor Stinner2019-10-084-4/+27
| | | | | | | | In debug mode, PyObject_GC_Track() now calls tp_traverse() of the object type to ensure that the object is valid: test that objects visited by tp_traverse() are valid. Fix pyexpat.c: only track the parser in the GC once the parser is fully initialized.
* bpo-36389: Add newline to _PyObject_AssertFailed() (GH-16629)Victor Stinner2019-10-071-0/+3
| | | | Add a newline between the verbose object dump and the Py_FatalError() logs for readability.
* bpo-38344: Fix syntax in activate.bat (GH-16533)James Abel2019-10-072-1/+2

* bpo-38294: Add list of no-longer-escaped chars to re.escape documentation. ↵Ricardo Bánffy2019-10-073-3/+7
| | | | | | | | | (GH-16442) Prior to 3.7, re.escape escaped many characters that don't have special meaning in Python, but that use to require escaping in other tools and languages. This commit aims to make it clear which characters were, but are no longer escaped.
* bpo-36389: Fix _PyBytesWriter in release mode (GH-16624)Victor Stinner2019-10-073-47/+48
| | | | Fix _PyBytesWriter API when Python is built in release mode with assertions.
* bpo-36389: _PyObject_CheckConsistency() available in release mode (GH-16612)Victor Stinner2019-10-0714-133/+148
| | | | | | | | | | | | | | | | | | | | | 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.
