bpo-41731: Make test_cmd_line_script pass with -vv (GH-22206)
Argument script_exec_args is usually an absolute file name,
but twice has form ['-m', 'module_name'].

bpo-40612: Fix SyntaxError edge cases in traceback formatting (GH-20072)
This fixes both the traceback.py module and the C code for formatting syntax errors (in Python/pythonrun.c). They now both consistently do the following:

- Suppress caret if it points left of text
- Allow caret pointing just past end of line
- If caret points past end of line, clip to *just* past end of line

The syntax error formatting code in traceback.py was mostly rewritten; small, subtle changes were applied to the C code in pythonrun.c.

There's still a difference when the text contains embedded newlines. Neither handles these very well, and I don't think the case occurs in practice.

bpo-40334: Fix error location upon parsing an invalid string literal (GH-19962)
When parsing a string with an invalid escape, the old parser used to
point to the beginning of the invalid string. This commit changes the new
parser to match that behaviour, since it's currently pointing to the
end of the string (or to be more precise, to the beginning of the next
token).

bpo-20443: No longer make sys.argv[0] absolute for script (GH-17534)
In Python 3.9.0a1, sys.argv[0] was made an asolute path if a filename
was specified on the command line. Revert this change, since most
users expect sys.argv to be unmodified.

bpo-20443: _PyConfig_Read() gets the absolute path of run_filename (GH-14053)
Python now gets the absolute path of the script filename specified on
the command line (ex: "python3 script.py"): the __file__ attribute of
the __main__ module, sys.argv[0] and sys.path[0] become an absolute
path, rather than a relative path.

* Add _Py_isabs() and _Py_abspath() functions.
* _PyConfig_Read() now tries to get the absolute path of
  run_filename, but keeps the relative path if _Py_abspath() fails.
* Reimplement os._getfullpathname() using _Py_abspath().
* Use _Py_isabs() in getpath.c.

Elvis Pranskevichus a6e956bcb0 bpo-34726: Fix handling of hash-based pycs in zipimport. (GH-10327)
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.

Alexey Izbyshev a2670565d8 bpo-32236: open() emits RuntimeWarning if buffering=1 for binary mode (GH-4842)
If buffering=1 is specified for open() in binary mode, it is silently
treated as buffering=-1 (i.e., the default buffer size).
Coupled with the fact that line buffering is always supported in Python 2,
such behavior caused several issues (e.g., bpo-10344, bpo-21332).

Warn that line buffering is not supported if open() is called with
binary mode and buffering=1.

bpo-34783: Fix test_nonexisting_script() (GH-9896)
Fix test_cmd_line_script.test_nonexisting_script(): the test must not
rely on sys.executable, since main.c uses config->program which can
be different than sys.executable in many cases (for example, on macOS
when using the framework).

bpo-34783: Disable test_nonexisting_script for macOS framework builds (GH-9831)
With macOS framework builds, test case test_nonexisting_script in
test_nonexisting_script fails because the test case assumes that
the file name in sys.executable will appear in the error message.
For macOS framework builds, sys.executable is the file name of the
stub launcher and its file name bears no relationship to the file
name of the actual python executable.  For now, skip the test in
this case.

bpo-33053: -m now adds *starting* directory to sys.path (GH-6231)
Historically, -m added the empty string as sys.path
zero, meaning it resolved imports against the current
working directory, the same way -c and the interactive
prompt do.

This changes the sys.path initialisation to add the
*starting* working directory as sys.path[0] instead,
such that changes to the working directory while the
program is running will have no effect on imports
when using the -m switch.

Previously AttributeError was raised, but that's not very reflective of the fact that the requested module can't be found since the specified parent isn't actually a package.

Nick Coghlan d2977a3ae2 bpo-29723: Consistently configure sys.path[0] (#575)
Directory and zipfile execution previously added
the parent directory of the directory or zipfile
as sys.path[0] and then subsequently overwrote
it with the directory or zipfile itself.

This caused problems in isolated mode, as it
overwrote the "stdlib as a zip archive" entry
in sys.path, as the parent directory was
never added.

The attempted fix to that issue in bpo-29319
created the opposite problem in *non*-isolated
mode, by potentially leaving the parent
directory on sys.path instead of overwriting it.

This change fixes the root cause of the problem
by removing the whole "add-and-overwrite" dance
for sys.path[0], and instead simply never adds
the parent directory to sys.path in the first
place.

Issue #26100:

* Add subprocess._optim_args_from_interpreter_flags()
* Add test.support.optim_args_from_interpreter_flags()
* Use new functions in distutils, test_cmd_line_script, test_compileall and
  test_inspect

The change enables test_details() test of test_inspect when -O or -OO command
line option is used.

and document and test that the module name must be absolute.

Martin Panter 657257edb6 Issue #14285: Do not catch __init__.py exceptions in runpy
Initialize package before calling find_spec() for __main__, so that we do not
incorrectly handle exceptions from __init__.py. When runpy is used from the
Python CLI, use an internal exception rather than ImportError, to avoid
catching unexpected exceptions.

Also remove exception message rewriting in _run_module_as_main(), because it
seems to be redundant with the _get_main_module_details() function.
