bpo-34066: Disabled interruption before SETUP_WITH and BEFORE_ASYNC_WITH. (GH-8159)
This will prevent emitting a resource warning when the execution was
interrupted by Ctrl-C between calling open() and entering a 'with' block
in "with open()".

Benjamin Peterson 95f1a7bb09 remove support for splitting the ceval switch into multiple switches (#4099)
This kludge is from 1992. Any C99 compiler is going to be able to handle the
ceval dispatch switch.

Anyway, we have much bigger switches than the ceval dispatch one around. (See,
e.g., Objects/unicodetype_db.h.)

Eric Snow 3f9eee6eb4 bpo-28411: Support other mappings in PyInterpreterState.modules. (#3593)
The concrete PyDict_* API is used to interact with PyInterpreterState.modules in a number of places. This isn't compatible with all dict subclasses, nor with other Mapping implementations. This patch switches the concrete API usage to the corresponding abstract API calls.

We also add a PyImport_GetModule() function (and some other helpers) to reduce a bunch of code duplication.

Nathaniel J. Smith ab4413a7e9 bpo-30039: Don't run signal handlers while resuming a yield from stack (#1081)
If we have a chain of generators/coroutines that are 'yield from'ing
each other, then resuming the stack works like:

- call send() on the outermost generator
- this enters _PyEval_EvalFrameDefault, which re-executes the
  YIELD_FROM opcode
- which calls send() on the next generator
- which enters _PyEval_EvalFrameDefault, which re-executes the
  YIELD_FROM opcode
- ...etc.

However, every time we enter _PyEval_EvalFrameDefault, the first thing
we do is to check for pending signals, and if there are any then we
run the signal handler. And if it raises an exception, then we
immediately propagate that exception *instead* of starting to execute
bytecode. This means that e.g. a SIGINT at the wrong moment can "break
the chain" – it can be raised in the middle of our yield from chain,
with the bottom part of the stack abandoned for the garbage collector.

The fix is pretty simple: there's already a special case in
_PyEval_EvalFrameEx where it skips running signal handlers if the next
opcode is SETUP_FINALLY. (I don't see how this accomplishes anything
useful, but that's another story.) If we extend this check to also
skip running signal handlers when the next opcode is YIELD_FROM, then
that closes the hole – now the exception can only be raised at the
innermost stack frame.

This shouldn't have any performance implications, because the opcode
check happens inside the "slow path" after we've already determined
that there's a pending signal or something similar for us to process;
the vast majority of the time this isn't true and the new check
doesn't run at all.

INADA Naoki 93fac8dd35 bpo-29676: fix lsprof can't profile C method call. (GH523)
When LOAD_METHOD is used for calling C mehtod, PyMethodDescrObject
was passed to profilefunc from 5566bbb.
But lsprof traces only PyCFunctionObject. Additionally, there can be
some third party extension which assumes passed arg is
PyCFunctionObject without calling PyCFunction_Check().

So make PyCFunctionObject from PyMethodDescrObject when
tstate->c_profilefunc is set.

Martijn Pieters d7e64337ef bpo-28598: Support __rmod__ for RHS subclasses of str in % string formatting operations (#51)
When you use `'%s' % SubClassOfStr()`, where `SubClassOfStr.__rmod__` exists, the reverse operation is ignored as normally such string formatting operations use the `PyUnicode_Format()` fast path. This patch tests for subclasses of `str` first and picks the slow path in that case.
