gh-115961: Add name and mode attributes for compressed file-like objects (GH-116036)
...
* 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'.

No longer use len() to get the length of the input data. For some buffer protocol objects,
the length obtained by using len() is wrong.

bpo-43785: Improve BZ2File performance by removing RLock (GH-25299)
...
Remove `RLock` from `BZ2File`. It makes `BZ2File` to thread unsafe, but
gzip and lzma don't use it too.

See [PEP 597](https://www.python.org/dev/peps/pep-0597/ ).
* Add `-X warn_default_encoding` and `PYTHONWARNDEFAULTENCODING`.
* Add EncodingWarning
* Add io.text_encoding()
* open(), TextIOWrapper() emits EncodingWarning when encoding is omitted and warn_default_encoding is enabled.
* _pyio.TextIOWrapper() uses UTF-8 as fallback default encoding used when failed to import locale module. (used during building Python)
* bz2, configparser, gzip, lzma, pathlib, tempfile modules use io.text_encoding().
* What's new entry

bpo-39357: Remove buffering parameter of bz2.BZ2File (GH-18028)

Remove the buffering parameter of bz2.BZ2File. Since Python 3.0, it
was ignored and using it was emitting a DeprecationWarning. Pass an
open file object to control how the file is opened.
The compresslevel parameter becomes keyword-only.
