This follows GNU gzip, which defaults to using 0 as the mtime
for compressing stdin, where no file mtime is involved.
This makes the output of gzip.compress() deterministic by default,
greatly helping reproducible builds.

This matches the output behavior in 3.10 and earlier; the optimization in 3.11 allowed the zlib library's "os" value to be filled in instead in the circumstance when mtime was 0. this keeps things consistent.
* Add name and mode attributes for compressed and archived file-like objects
in modules bz2, lzma, tarfile and zipfile.
* Change the value of the mode attribute of GzipFile from integer (1 or 2)
to string ('rb' or 'wb').
* Change the value of the mode attribute of ZipExtFile from 'r' to 'rb'.
* Fix Sphinx warning in library/xml.rst
Direct use of the pyexpat module is deprecated, but this is how to check the version for security purposes
* Fix Sphinx warning in library/importlib.resources.rst
* Use italics for parameters
* Link to the exception
* Fix Sphinx warning in library/gzip.rst
* Document message and header defect base classes to fix Sphinx warning in library/email.headerregistry.rst
* Restore feed_eof() doc to fix Sphinx warning in library/asyncio-stream.rst
* Fix Sphinx warning in extending/newtypes.rst
* Fix Sphinx warning in c-api/set.rst
On stdtypes.rst, set and frozenset are documented together and the frozenset has the working refs
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.
Without setting mtime, time.time() will be used as the timestamp which will
end up in the compressed data and each invocation of the compress() function
will vary over time.
This changes the main documentation, doc strings, source code comments, and a
couple error messages in the test suite. In some cases the word was removed
or edited some other way to fix the grammar.
GzipFile, BZ2File or LZMAFile. This defeats denial of service attacks
using compressed bombs (i.e. compressed payloads which decompress to a huge
size).
Patch by Martin Panter and Nikolaus Rath.
- Remove duplicated list of links to the other modules from each
module’s doc (people can already go up to library/archiving and
there they can see the list).
- Link to shutil high-level operations.
