beets 2.3 doesn't like dots in the filename patterns

[cybersphinx]

Problem

Running beet import on any album with

paths:
    default: $albumartist/$album%aunique{}/$track. $title

in the configuration results in filenames like 01.flac, i.e. everything after the dot is missing.

Investigation

Looking for "path" in the git log brings up the very recently merged #5224, which introduced os.path.splitext in https://github.com/beetbox/beets/blob/master/beets/util/__init__.py#L767 and adding some prints for path, first_stage and second_stage shows what happens when you also change the configuration to

paths:
    default: $albumartist/$album%aunique{}/$track. $title.x.y

path is the filename without extension, first_stage removes the .y, and second_stage the .x.

Solutions?

Not sure. The above config is a workaround, adding a +suffix to the path passed to the three _legalize_stage calls kinda works but shows

Fell back to default replacements when naming file Artist/Album/01. Title.x.y. Configure replacements to avoid lengthening the filename.

Anyway, something in there expects a filename containing a dot to have an extension, but the filename used doesn't have the extension added.

Further to this I have the following defined in replace and still get the above warning

replace:
  '^\.\.\.': "…"
  '^\.\.': "‥"
  '^\.': "․"
  '\.\.\.': "…"
  '\.\.\.$': "…"
  '\.\.$': "‥"
  '\.\.': "‥"
  '\.$': "․"

Single U+002E at start or end is replaced with U+2024

Apologies, my bad! I will look at this later tonight.

Seems to work fine, didn't notice problems on the one album I tested so far. Thanks!

Made the changes and now it works just fine on the files I had issues with. Thank you!
