bpo-21016, bpo-1294959: The pydoc and trace modules now use the
sysconfig module to get the path to the Python standard library, to
support uncommon installation path like /usr/lib64/python3.9/ on
Fedora.

This is the converse of GH-15353 -- in addition to plenty of
scripts in the tree that are marked with the executable bit
(and so can be directly executed), there are a few that have
a leading `#!` which could let them be executed, but it doesn't
do anything because they don't have the executable bit set.
Here's a command which finds such files and marks them. The
first line finds files in the tree with a `#!` line *anywhere*;
the next-to-last step checks that the *first* line is actually of
that form. In between we filter out files that already have the
bit set, and some files that are meant as fragments to be
consumed by one or another kind of preprocessor.
$ git grep -l '^#!' \
| grep -vxFf <( \
git ls-files --stage \
| perl -lane 'print $F[3] if (!/^100644/)' \
) \
| grep -ve '\.in$' -e '^Doc/includes/' \
| while read f; do
head -c2 "$f" | grep -qxF '#!' \
&& chmod a+x "$f"; \
done
Previously, it was hard to tell whether a function should be awaited. It was also incorrect (per PEP 484) to put this in the type hint for coroutine functions. Added this info to the output of builtins.help and pydoc.

Replace time.time() with time.monotonic() in tests to measure time
delta.
test_zipfile64: display progress every minute (60 secs) rather than
every 5 minutes (5*60 seconds).
For builtin types with builtin subclasses, help() on the type now shows up
to 4 of the subclasses. This partially replaces the exception hierarchy
information previously displayed in Python 2.7.
The pydoc CLI assumed -m pydoc would add the empty string
to sys.path, and hence got confused when it switched to
adding the full initial working directory instead.
This refactors the pydoc CLI path manipulation to be
more testable, and ensures it won't accidentally
remove the standard library directory containing
pydoc itself from sys.path.
* bpo-31238: pydoc ServerThread.stop() now joins itself
ServerThread.stop() now joins itself to wait until
DocServer.serve_until_quit() completes and then explicitly sets
its docserver attribute to None to break a reference cycle.
* Add NEWS.d entry
The concept of .pyo files no longer exists. Now .pyc files have an
optional `opt-` tag which specifies if any extra optimizations beyond
the peepholer were applied.
The previous patch only dealt with KeyboardInterrupt when all of the
data had been consumed by the pager. This deals with the interrupt
when some data is still pending.
Previously, if you hit ctl-c while the pager was active, the python that
launched the subprocess for the pager would see the KeyboardInterrupt in the
__exit__ method of the subprocess context manager where it was waiting for the
subprocess to complete, ending the wait. This would leave the pager running,
while the interactive interpreter, after handling the exception by printing
it, would go back to trying to post a prompt...but the pager would generally
have the terminal in raw mode, and in any case would be still trying to read
from stdin. On some systems, even exiting python at that point would not
restore the terminal mode. The problem with raw mode could also happen if
ctl-C was hit when pydoc was called from the shell command line and the pager
was active.
Instead, we now wait on the subprocess in a loop, ignoring KeyboardInterrupt
just like the pager does, until the pager actually exits.
(Note: this was a regression relative to python2...in python2 the pager
is called via system, and system does not return until the pager exits.)
Along the way, dismantle importlib._bootstrap._SpecMethods as it was
no longer relevant and constructing the new function required
partially dismantling the class anyway.
for bound methods. Previous to this change, it displayed "self" for methods
implemented in Python but not methods implemented in C; it is now both
internally consistent and consistent with inspect.Signature.
PyMethodDescr_Type, _PyMethodWrapper_Type, and PyWrapperDescr_Type)
have been modified to provide introspection information for builtins.
Also: many additional Lib, test suite, and Argument Clinic fixes.
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.
ImportError.
The exception is raised by import when a module could not be found.
Technically this is defined as no viable loader could be found for the
specified module. This includes ``from ... import`` statements so that
the module usage is consistent for all situations where import
couldn't find what was requested.
This should allow for the common idiom of::
try:
import something
except ImportError:
pass
to be updated to using ModuleNotFoundError and not accidentally mask
ImportError messages that should propagate (e.g. issues with a
loader).
This work was driven by the fact that the ``from ... import``
statement needed to be able to tell the difference between an
ImportError that simply couldn't find a module (and thus silence the
exception so that ceval can raise it) and an ImportError that
represented an actual problem.
This fixes a regression relative to Python2. (In 2, methods on a class were
unbound methods and matched the inspect queries being done, in 3 they are just
functions and so were missed).
This is an undocumented function that pydoc itself does not use, but
I found that numpy at least uses it in its documentation generator.
