* bpo-43950: optimize column table assembling with pre-sizing object (GH-26997)Batuhan Taskaya2021-07-021-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | The new resizing system works like this; ``` $ cat t.py a + a + a + b + c + a + a + a + b + c + a + a + a + b + c + a + a + a + b + c [repeated 99 more times] $ ./python t.py RESIZE: prev len = 32, new len = 66 FINAL SIZE: 56 ----------------------------------------------------- RESIZE: prev len = 32, new len = 66 RESIZE: prev len = 66, new len = 134 RESIZE: prev len = 134, new len = 270 RESIZE: prev len = 270, new len = 542 RESIZE: prev len = 542, new len = 1086 RESIZE: prev len = 1086, new len = 2174 RESIZE: prev len = 2174, new len = 4350 RESIZE: prev len = 4350, new len = 8702 FINAL SIZE: 8004 ``` So now we do considerably lower number of `_PyBytes_Resize` calls.

* bpo-43950: Add code.co_positions (PEP 657) (GH-26955)Pablo Galindo2021-07-026-5138/+7118
| | | | | | | | | | | | | | | This PR is part of PEP 657 and augments the compiler to emit ending line numbers as well as starting and ending columns from the AST into compiled code objects. This allows bytecodes to be correlated to the exact source code ranges that generated them. This information is made available through the following public APIs: * The `co_positions` method on code objects. * The C API function `PyCode_Addr2Location`.

| | | | | | | | | (GH-26809) A TypeError is now raised instead of an AttributeError in "with" and "async with" statements for objects which do not support the context manager or asynchronous context manager protocols correspondingly.

| | | | | | All uses of this flag are either setting it or in doc or tests for it. So we should be able to get rid of it completely.

| | | | | Py_RunMain() now resets PyImport_Inittab to its initial value at exit. It must be possible to call PyImport_AppendInittab() or PyImport_ExtendInittab() at each Python initialization.

* bpo-44466: Faulthandler now detects the GC (GH-26823)Victor Stinner2021-06-211-0/+4
| | | | The faulthandler module now detects if a fatal error occurs during a garbage collector collection (only if all_threads is true).

* bpo-43693: Eliminate unused "fast locals". (gh-26587)Eric Snow2021-06-154-4011/+4096
| | | | | Currently, if an arg value escapes (into the closure for an inner function) we end up allocating two indices in the fast locals even though only one gets used. Additionally, using the lower index would be better in some cases, such as with no-arg `super()`. To address this, we update the compiler to fix the offsets so each variable only gets one "fast local". As a consequence, now some cell offsets are interspersed with the locals (only when an arg escapes to an inner function). https://bugs.python.org/issue43693
