FYI: the develop branch of feedparser does not work with current version of libxml2 (2.13.3)

To make a long story short, I discovered that the develop branch of feedparser does not work with the current release of libxml2. More discussion is here: lemon24/reader#350

This is problematic because feedparser explicitly prefers using the libxml2 driver, if available:

feedparser/feedparser/api.py

Line 49 in 11990ea

PREFERRED_XML_PARSERS = ["drv_libxml2"]

The master branch (which corresponds to the current release) does not have this problem, as it always callssource.setByteStream() and never source.setByteStream():

feedparser/feedparser/api.py

Line 261 in 6cdc208

source.setByteStream(io.BytesIO(data))

I tracked the cause down to libxml2's handling of text streams (instead of binary streams) and filed an issue upstream here: https://gitlab.gnome.org/GNOME/libxml2/-/issues/790. Fortunately this issue was promptly fixed! But the develop branch of feedparser should not be released until that fix in libxml2 has been released, because otherwise, feedparser won't work when libxml2 is installed.

To follow up: the bug fix was released in libxml2 v2.13.4, so I'll close this issue.
