Package: src:plastex

Severity: important
Hi!
While rebuilding the python related packages against the Python 3.15rc2
version we found that plastex fails to build from source:
https://debusine.debian.net/debian/r-python-python3.15/artifact/4856615/
There are a lot of tests that are failing with errors like this one:
def test_colorparser_next():
c = ColorParser()
c.scan('1 2 3 4')
unittests/Packages/xcolor.py:5:
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _
plasTeX/Packages/xcolor.py:524: in scan
scanner = Scanner([
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _
self = <re.Scanner object at 0x7efc938870e0>
lexicon = [(',\\s*', <function ColorParser.scan.<locals>.<lambda> at
0x7efc93a11380>),
('RGB|rgb|cmyk|cmy|HSB|hsb|Gray|gray|HTML...als>.<lambda> at
0x7efc93a135e0>), ('[-+]?\\d+', <function
ColorParser.scan.<locals>.<lambda> at 0x7efc93a13690>), ...]
flags = 0
def __init__(self, lexicon, flags=0):
from ._constants import BRANCH, SUBPATTERN
if isinstance(flags, RegexFlag):
flags = flags.value
self.lexicon = lexicon
# combine phrases into a compound pattern
p = []
s = _parser.State()
s.flags = flags
for phrase, action in lexicon:
sub_pattern = _parser.parse(phrase, flags)
if sub_pattern.state.groups != 1:
raise ValueError("Cannot use capturing groups in
re.Scanner")
E ValueError: Cannot use capturing groups in re.Scanner
This was a change in behaviour in Python 3.15 and the code needs to get
adapted:
https://github.com/python/cpython/issues/140797
Setting the severity to important for now. Once Python 3.15 is released
and later added to python3-defaults, this bug will become release
critical.
