Seems in the past the copy of builtins was not made in some scenarios,
and the error was silenced. Write it now to stderr, so we have a chance
to see it.

Make _struct.Struct a GC type

This fixes a memory leak in the _struct module, where as soon
as a Struct object is stored in the cache, there's a cycle from
the _struct module to the cache to Struct objects to the Struct
type back to the module. If _struct.Struct is not gc-tracked, that
cycle is never collected.

This PR makes _struct.Struct GC-tracked, and adds a regression test.

`tarfile` already accepts a compressionlevel argument for creating
files. This patch adds the same for stream-based tarfile usage.
The default is 9, the value that was previously hard-coded.

…ramSpec, etc (GH-31148)

The existing test covering this case passed only incidentally. We
explicitly disallow doing this and add a proper error message.

Sync up co_code changes with 3.11 commit 852b4d4.

…scription (#92761)

The urllib.request no longer uses the deprecated check_hostname
parameter of the http.client module.

Add private http.client._create_https_context() helper to http.client,
used by urllib.request.

Remove the now redundant check on check_hostname and verify_mode in
http.client: the SSLContext.check_hostname setter already implements
the check.

…h tests (GH-94206)

- c_longlong and c_longdouble need experimental WASM bigint.
- Skip tests that need threading
- Define ``CTYPES_MAX_ARGCOUNT`` for Emscripten. libffi-emscripten 2022-06-23 supports up to 1000 args.

The message was only emitted when the build succeeded _and_ there were
missing modules.

gzip: Remove the filename attribute of gzip.GzipFile,
deprecated since Python 2.6, use the name attribute instead. In write
mode, the filename attribute added '.gz' file extension if it was not
present.

Remove the ssl.RAND_pseudo_bytes() function, deprecated in Python
3.6: use os.urandom() or ssl.RAND_bytes() instead.

Remove io.OpenWrapper and _pyio.OpenWrapper, deprecated in Python
3.10: just use :func:`open` instead. The open() (io.open()) function
is a built-in function. Since Python 3.10, _pyio.open() is also a
static method.

…RequestHandler (GH-31985)

* Add an index_pages default list to SimpleHTTPRequestHandler and an
optional constructor parameter that allows the default indexes pages
list to be overridden.  This makes it easy to set a new index page name
without having to override send_head.

Make sure statements that have run to completion or errored are
reset and cleared off the cursor for all paths in execute() and
executemany().

…ypes (GH-91457)

When used with plain Enum, auto() returns the last numeric value assigned, skipping any incompatible member values (such as strings); starting in 3.13 the default auto() for plain Enums will require all the values to be of compatible types, and will return a new value that is 1 higher than any existing value.
