* bpo-31499, xml.etree: Fix xmlparser_gc_clear() crash (#3641)Victor Stinner2017-09-181-1/+5
| | | | | | | | | | * bpo-31499, xml.etree: Fix xmlparser_gc_clear() crash xml.etree: xmlparser_gc_clear() now sets self.parser to NULL to prevent a crash in xmlparser_dealloc() if xmlparser_gc_clear() was called previously by the garbage collector, because the parser was part of a reference cycle. Co-Authored-By: Serhiy Storchaka <storchaka@gmail.com>
* bpo-31455: Fix an assertion failure in ElementTree.XMLParser(). (#3545)scoder2017-09-141-2/+33
| | | | | | * Avoid calling "PyObject_GetAttrString()" (and potentially executing user code) with a live exception set. * Ignore only AttributeError on attribute lookups in ElementTree.XMLParser() and propagate all other exceptions.
* bpo-31428: Prevent raising a SystemError in case the memo arg of ↵Oren Milman2017-09-121-4/+5
| | | | ElementTree.Element.__deepcopy__() isn't a dictionary. (#3512)

* bpo-30892: Fix _elementtree module initialization (#2647)Victor Stinner2017-07-101-0/+5
| | | | Handle getattr(copy, 'deepcopy') error in _elementtree module initialization.
* bpo-29464: Rename METH_FASTCALL to METH_FASTCALL|METH_KEYWORDS and make (#1955)Serhiy Storchaka2017-07-031-1/+1
| | | | | the bare METH_FASTCALL be used for functions with positional-only parameters.
* bpo-30061: Check if PyObject_Size()/PySequence_Size()/PyMapping_Size() (#1096)Serhiy Storchaka2017-04-191-2/+2

* bpo-29204: Emit warnings for already deprecated ElementTree features. (#773)Serhiy Storchaka2017-03-301-2/+37
| | | | | | | | Element.getiterator() and the html parameter of XMLParser() were deprecated only in the documentation (since Python 3.2 and 3.4 correspondintly). Now using them emits a deprecation warning. * Don’t need check_warnings any more.
* bpo-27863: Fixed multiple crashes in ElementTree. (#765)Serhiy Storchaka2017-03-301-48/+52

* Run Argument Clinic: METH_VARARGS=>METH_FASTCALLVictor Stinner2017-01-171-1/+1
| | | | | | | | Issue #29286. Run Argument Clinic to get the new faster METH_FASTCALL calling convention for functions using "boring" positional arguments. Manually fix _elementtree: _elementtree_XMLParser_doctype() must remain consistent with the clinic code.

* | | Use PyObject_CallFunctionObjArgs()Victor Stinner2016-12-091-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #28915: Replace PyObject_CallFunction() with PyObject_CallFunctionObjArgs() when the format string was only made of "O" formats, PyObject* arguments. PyObject_CallFunctionObjArgs() avoids the creation of a temporary tuple and doesn't have to parse a format string.
* | | Use _PyObject_CallMethodIdObjArgs() in _elementtreeVictor Stinner2016-12-091-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #28915: Replace _PyObject_CallMethodId() with _PyObject_CallMethodIdObjArgs() when the format string was only made of "O" formats, PyObject* arguments. _PyObject_CallMethodIdObjArgs() avoids the creation of a temporary tuple and doesn't have to parse a format string.
* | | Issue #28858: Remove _PyObject_CallArg1() macroVictor Stinner2016-12-051-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace _PyObject_CallArg1(func, arg) with PyObject_CallFunctionObjArgs(func, arg, NULL) Using the _PyObject_CallArg1() macro increases the usage of the C stack, which was unexpected and unwanted. PyObject_CallFunctionObjArgs() doesn't have this issue.
* | | Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-1/+1
| | | | | | | | | | | | | | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* | | Replace PyObject_CallFunction() with fastcallVictor Stinner2016-12-011-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace PyObject_CallFunction(func, "O", arg) and PyObject_CallFunction(func, "O", arg, NULL) with _PyObject_CallArg1(func, arg) Replace PyObject_CallFunction(func, NULL) with _PyObject_CallNoArg(func) _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack.
* | | Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.
