Public bug reported:
Ubuntu version: Ubuntu 24.04.1 LTS
hplib package: Installed: 3.23.12+dfsg0-0ubuntu5
The hplip package has errors in the regular expression patterns where
the strings are not raw strings and therefore has invalid escape
sequences.
These were reported by an an apt-upgrade. I expected it to pass without
errors, but this happened:
Setting up python3 (3.12.3-0ubuntu2) ...
running python rtupdate hooks for python3.12...
/usr/share/hplip/base/imagesize.py:186: SyntaxWarning: invalid escape sequence
'\#'
re.compile('\#define\s+\S+\s+\d+') : ('image/x-xbitmap', xbmsize),
/usr/share/hplip/base/imagesize.py:187: SyntaxWarning: invalid escape sequence
'\/'
re.compile('\/\* XPM \*\/') : ('image/x-xpixmap', xpmsize),
/usr/share/hplip/base/imagesize.py:189: SyntaxWarning: invalid escape sequence
'\*'
re.compile('^II\*\x00') : ('image/tiff', tiffsize),
/usr/share/hplip/fax/ledmfax.py:46: SyntaxWarning: invalid escape sequence '\d'
http_result_pat = re.compile(b"""HTTP/\d.\d\s(\d+)""", re.I)
The consequences of this is unknown, but it will likely make the code
unable to provide the correct image size for XBM images and possibly
some more.
