clang's MemorySanitizer understand getc() but does not understand getc_unlocked(). Workaround: Don't use it on msan builds.

The warnings module now suggests to enable tracemalloc if the source is specified, tracemalloc module is available, but tracemalloc is not tracing memory allocations.

Adds configure flags for msan and ubsan builds to make it easier to enable. These also encode the detail that address sanitizer and memory sanitizer should disable pymalloc. Define MEMORY_SANITIZER when appropriate at build time and adds workarounds to existing code to mark things as initialized where the sanitizer is otherwise unable to determine that. This lets our build succeed under the memory sanitizer. not all tests pass without sanitizer failures yet but we're in pretty good shape after this.

Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h

* universal_newlines defaulting to False would suggest, that not specifying universal_newlines explicitly and setting text to True should cause an error, which is not the case. * The run function didn't have the universal_newlines parameter documented * The check_output function didn't have its text parameter documented

The documentation was not covering multiple targets enclosed by parenthesis nor multiple targets enclosed by brackets, adding them all would be heavy, an else cover them all and is lighter to read.

* ast.h now includes Python-ast.h and node.h * parsetok.h now includes node.h and grammar.h * symtable.h now includes Python-ast.h * Modify asdl_c.py to enhance Python-ast.h: * Add #ifndef/#define Py_PYTHON_AST_H to be able to include the header twice * Add "extern { ... }" for C++ * Undefine "Yield" macro conflicting with winbase.h * Remove "#undef Yield" from C files, it's now done in Python-ast.h * Remove now useless includes in C files

This function may access memory which is mapped but is considered free by libc allocator. It behaves so by design, therefore we need to suppress sanitizer reports. GCC doesn't support MSan, so disable only TSan for it.

* _PyTuple_ITEMS() gives access to the tuple->ob_item field and cast the first argument to PyTupleObject*. This internal macro is only usable if Py_BUILD_CORE is defined. * Replace &PyTuple_GET_ITEM(ob, 0) with _PyTuple_ITEMS(ob). * Replace PyTuple_GET_ITEM(op, 1) with &_PyTuple_ITEMS(ob)[1].

* All internal header files now require Py_BUILD_CORE or Py_BUILD_CORE_BUILTIN to be defined. * _json.c is now compiled with Py_BUILD_CORE_BUILTIN to access pycore_accu.h header. * Add an example to Modules/Setup to show how to build _json as a built-in module; it requires non trivial compiler options.

Currently, the *n* and *total* variables get converted to floats each time they are multiplied by random(). This minor tweak does the conversion just once and gets a small speedup (approx 3%).

Gives approx 20% speed-up using clang depending on the number of elements in the set (the less dense the set, the more the speed-up). Uses the same entry++ logic used elsewhere in the setobject.c code.

1) Convert weird field name "typ" to the more standard "type". 2) For the NUMBER type, convert the value to an int() or float(). 3) Simplify ``group(kind)`` to the shorter and faster ``group()`` call. 4) Simplify logic go a single if-elif chain to make this easier to extend. 5) Reorder the tests to match the order the tokens are specified. This isn't necessary for correctness but does make the example easier to follow. 6) Move the "column" calculation before the if-elif chain so that users have the option of using this value in error messages.

Since the n==1 case just returns *max*, it cannot be larger than the magnitude of the vector entry.

This typo doesn't affect the result because wrong bits are discarded on implicit conversion to unsigned char, but it trips UBSan with -fsanitize=implicit-integer-truncation. https://bugs.python.org/issue35194

Fix an off by one error in the peephole optimizer when checking for unreachable code beyond a return. Do a bounds check within find_op so it can return before going past the end as a safety measure. https://github.com/python/cpython/commit/7db3c488335168993689ddae5914a28e16188447#diff-a33329ae6ae0bb295d742f0caf93c137 introduced this off by one error while fixing another one nearby. This bug was shipped in all Python 3.6 and 3.7 releases. The included unittest won't fail unless you do a clang msan build.

The call to `_untrack_reader` is performed too soon, causing the protocol to forget about the reader before `connection_lost` can run and feed the EOF to the reader. See bpo-35065.

Current support for hash-based bytecode files in `zipimport` is rather sparse, which leads to test failures when the test suite is ran with the ``SOURCE_DATE_EPOCH`` environment variable set. This teaches zipimport to handle hash-based pycs properly.
