Overview

What was previously Lib/_compression.py is now Lib/compression/_common/_streams.py, and the original file has been removed. During this update process, test files also needed updating, and related compression module files were changed as of version 3.14.2.

As a note: The test_zstd file has been newly added, but since _zstd is not yet supported, it is automatically skipped so the test will not fail.

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.

Are you also interested in xz and zstd support?

@youknowone I'm not very familiar with compression algorithms, so if I get the chance to study them, I'd be really happy. However, due to other personal things to do, I won't be able to look into this issue for at least three days. So if the issue is still open in a few days, I'll take a look at it one by one.

I've also created a zstd issue! #6793
