Thomas Kluyver f9169ce6b4 bpo-25532: Protect against infinite loops in inspect.unwrap() (#1717)
Some objects (like test mocks) auto-generate new objects on
attribute access, which can lead to an infinite loop in
inspect.unwrap().

Ensuring references are retained to otherwise temporary objects
and capping the size of the memo dict turns this case into a
conventional exception instead.

Nate fcfe80ec25 bpo-29822: Make inspect.isabstract() work during __init_subclass__. (#678)
At the time when an abstract base class' __init_subclass__ runs,
ABCMeta.__new__ has not yet finished running, so in the presence of
__init_subclass__, inspect.isabstract() can no longer depend only on
TPFLAGS_IS_ABSTRACT.

Meador Inge f98c35a816 Issue #24485: Function source inspection fails on closures.
The fix for Issue #21217 introduced a regression that caused
`inspect.getsource` to return incorrect results on nested
functions.  The root cause of the regression was due to
switching the implementation to analyze the underlying
bytecode instead of the source code.

This commit switches things back to analyzing the source code
in a more complete way.  The original bug and the regression
are both fixed by the new source code analysis.

Yury Selivanov fdbeb2b4b6 Issue #24400: Resurrect inspect.isawaitable()
collections.abc.Awaitable and collections.abc.Coroutine no longer
use __instancecheck__ hook to detect generator-based coroutines.

inspect.isawaitable() can be used to detect generator-based coroutines
and to distinguish them from regular generator objects.

Yury Selivanov a74b5e59af Issue #24400: Remove inspect.isawaitable().
isawaitable() was added before collections.abc.Awaitable; now,
with Awaitable, it is no longer needed (we don't have ishashable()
or isiterable() methods in the inspect module either).

Yury Selivanov 5376ba9630 Issue #24400: Introduce a distinct type for 'async def' coroutines.
Summary of changes:

1. Coroutines now have a distinct, separate from generators
   type at the C level: PyGen_Type, and a new typedef PyCoroObject.
   PyCoroObject shares the initial segment of struct layout with
   PyGenObject, making it possible to reuse existing generators
   machinery.  The new type is exposed as 'types.CoroutineType'.

   As a consequence of having a new type, CO_GENERATOR flag is
   no longer applied to coroutines.

2. Having a separate type for coroutines made it possible to add
   an __await__ method to the type.  Although it is not used by the
   interpreter (see details on that below), it makes coroutines
   naturally (without using __instancecheck__) conform to
   collections.abc.Coroutine and collections.abc.Awaitable ABCs.

   [The __instancecheck__ is still used for generator-based
   coroutines, as we don't want to add __await__ for generators.]

3. Add new opcode: GET_YIELD_FROM_ITER.  The opcode is needed to
   allow passing native coroutines to the YIELD_FROM opcode.

   Before this change, 'yield from o' expression was compiled to:

      (o)
      GET_ITER
      LOAD_CONST
      YIELD_FROM

   Now, we use GET_YIELD_FROM_ITER instead of GET_ITER.

   The reason for adding a new opcode is that GET_ITER is used
   in some contexts (such as 'for .. in' loops) where passing
   a coroutine object is invalid.

4. Add two new introspection functions to the inspec module:
   getcoroutinestate(c) and getcoroutinelocals(c).

5. inspect.iscoroutine(o) is updated to test if 'o' is a native
   coroutine object.  Before this commit it used abc.Coroutine,
   and it was requested to update inspect.isgenerator(o) to use
   abc.Generator; it was decided, however, that inspect functions
   should really be tailored for checking for native types.

6. sys.set_coroutine_wrapper(w) API is updated to work with only
   native coroutines.  Since types.coroutine decorator supports
   any type of callables now, it would be confusing that it does
   not work for all types of coroutines.

7. Exceptions logic in generators C implementation was updated
   to raise clearer messages for coroutines:

   Before: TypeError("generator raised StopIteration")
   After: TypeError("coroutine raised StopIteration")

Larry Hastings 581ee3618c Issue #20326: Argument Clinic now uses a simple, unique signature to
annotate text signatures in docstrings, resulting in fewer false
positives.  "self" parameters are also explicitly marked, allowing
inspect.Signature() to authoritatively detect (and skip) said parameters.

Issue #20326: Argument Clinic now generates separate checksums for the
input and output sections of the block, allowing external tools to verify
that the input has not changed (and thus the output is not out-of-date).

Larry Hastings 5c66189e88 Issue #20189: Four additional builtin types (PyTypeObject,

Larry Hastings 2a727916c5 Issue #20226: Major improvements to Argument Clinic.
* You may now specify an expression as the default value for a
  parameter!  Example: "sys.maxsize - 1".  This support is
  intentionally quite limited; you may only use values that
  can be represented as static C values.
* Removed "doc_default", simplified support for "c_default"
  and "py_default".  (I'm not sure we still even need
  "py_default", but I'm leaving it in for now in case a
  use presents itself.)
* Parameter lines support a trailing '\\' as a line
  continuation character, allowing you to break up long lines.
* The argument parsing code generated when supporting optional
  groups now uses PyTuple_GET_SIZE instead of PyTuple_GetSize,
  leading to a 850% speedup in parsing.  (Just kidding, this
  is an unmeasurable difference.)
* A bugfix for the recent regression where the generated
  prototype from pydoc for builtins would be littered with
  unreadable "=<object ...>"" default values for parameters
  that had no default value.
* Converted some asserts into proper failure messages.
* Many doc improvements and fixes.

Ethan Furman b0c84cdaac Issue #19030: final pieces for proper location of various class attributes located in the metaclass.
Okay, hopefully the very last patch for this issue.  :/

I realized when playing with Enum that the metaclass attributes weren't always displayed properly.

New patch properly locates DynamicClassAttributes, virtual class attributes (returned by __getattr__ and friends), and metaclass class attributes (if they are also in the metaclass __dir__ method).

Also had to change one line in pydoc to get this to work.

Added tests in test_inspect and test_pydoc to cover these situations.

Ethan Furman 63c141cacd Close #19030: inspect.getmembers and inspect.classify_class_attrs
Order of search is now:
  1. Try getattr
  2. If that throws an exception, check __dict__ directly
  3. If still not found, walk the mro looking for the eldest class that has
     the attribute (e.g. things returned by __getattr__)
  4. If none of that works (e.g. due to a buggy __dir__, __getattr__, etc.
     method or missing __slot__ attribute), ignore the attribute entirely.

Ethan Furman e03ea37a7b Close #19030: improvements to inspect and Enum.
inspect.getmembers and inspect.classify_class_attrs now search the metaclass
mro for types.DynamicClassAttributes (what use to be called
enum._RouteClassAttributeToGetattr); in part this means that these two
functions no longer rely solely on dir().

Besides now returning more accurate information, these improvements also
allow a more helpful help() on Enum classes.

Brett Cannon e4f41deccf Issue #17177: The imp module is pending deprecation.

Brett Cannon 4c14b5de1c #17115,17116: Have modules initialize the __package__ and __loader__
attributes to None.

The long-term goal is for people to be able to rely on these
attributes existing and checking for None to see if they have been
set. Since import itself sets these attributes when a loader does not
the only instances when the attributes are None are from someone
overloading __import__() and not using a loader or someone creating a
module from scratch.

This patch also unifies module initialization. Before you could have
different attributes with default values depending on how the module
object was created. Now the only way to not get the same default set
of attributes is to circumvent initialization by calling
ModuleType.__new__() directly.

Brett Cannon cb66eb0dec Issue #13959: Deprecate imp.get_suffixes() for new attributes on
importlib.machinery that provide the suffix details for import.
The attributes were not put on imp so as to compartmentalize
everything importlib needs for setting up imports in
importlib.machinery.

This also led to an indirect deprecation of inspect.getmoduleinfo() as
it directly returned imp.get_suffix's returned tuple which no longer
makes sense.
