[New-bugs-announce] [issue37005] bz2 module doesn't write end-of-stream marker

[Dobatymo]

New submission from Dobatymo <the-real-hazzard at outlook.com>:

According to https://en.wikipedia.org/wiki/Bzip2 the reference implementation of bzip2 writes an end-of-stream marker (also called stream footer) with a magic number and a stream checksum to the file.

Python does not do so. The files can still be read by all bzip2 compatible software I tried. For completeness and better error detection however, writing this marker (optionally maybe) would be useful.
