Package: debmake
Version: 4.4.0-3
Severity: minor
Dear Maintainer,
Using debmake on unstable with Python 3.12 installed. While installing
debmake with apt-get, a long series of warnings were produced similar to
this:
Setting up debmake (4.4.0-3) ...
/usr/lib/python3/dist-packages/debmake/__main__.py:304: SyntaxWarning: invalid escape sequence '\/'
+ ' -type f 2>&1 | sed -e "s/^debian\/'
/usr/lib/python3/dist-packages/debmake/__main__.py:306: SyntaxWarning: invalid escape sequence '\/'
+ '\///" | sort >../{0}.install.log'.format(para["package"])
The package should install cleanly without warnings. These warnings do
not seem to affect the functionality as Python 3.12 simply falls back to
3.11 behavior after producing the warning.

Hi,
As I checked https://docs.python.org/3/whatsnew/3.12.html
A backslash-character pair that is not a valid escape sequence now generates
a SyntaxWarning, instead of DeprecationWarning. For example,
re.compile("\d+\.\d+") now emits a SyntaxWarning ("\d" is an invalid escape
sequence, use raw strings for regular expression: re.compile(r"\d+\.\d+")).
In a future Python version, SyntaxError will eventually be raised, instead of
SyntaxWarning. (Contributed by Victor Stinner in gh-98401.)
I suppose I need to use raw string explicitly.
This is nasty change which affects many code out there. Sigh.
Osamu
