Fix SyntaxWarning in regex patterns (Bug #1085657)

Gonzalo Silvalde Blancorequested to merge
gonzaloSilvalde/jube:fix-bug-1085657 into main

This merge request fixes a trivial but annoying bug in the jube package (version 2.7.1-2). During piuparts tests, SyntaxWarnings were emitted due to invalid escape sequences in two regex patterns:

  • In jube/benchmark.py, the regex used for splitting filenames was causing a warning because the escape sequence '\.' was not interpreted literally.
  • In jube/util/util.py, a similar warning occurred for the pattern '\$'.

To resolve these warnings, this patch adds the raw string prefix (r"") to both regex patterns. This change ensures that backslashes are treated as literal characters, thus eliminating the SyntaxWarnings.
