Fix logging in tests (#6853)

Summary

• Add a CLI logging handler that resolves sys.stderr when each log
  record is emitted.
• Keep CLI logs attached to the current stderr stream when callers
  temporarily replace it for capture or redirection.
• Avoid retaining pytest's closed per-test capture stream across
  repeated CLI invocations.

Problem

The issue is that the first CLI command run under pytest can install a
StreamHandler bound to pytest's temporary stderr capture stream.
Pytest later closes that stream, but the global beets logger keeps the
handler around for the next CLI invocation.

This was introduced by #6755, which removed logging setup as an import
side effect and moved CLI logging bootstrap into command startup.

Before #6755, the handler was created when beets.ui was imported. In
tests, that usually happened before pytest swapped in its per-test
stderr capture stream. After #6755, the handler is created when
_raw_main() runs, which means it can be created while pytest capture
is active.

The important bit is that logging.StreamHandler() stores the stream it
sees at creation time. So it ends up holding on to pytest's temporary
stderr stream from the first command. Once pytest closes that stream,
later debug/info logs try to write to a closed file and Python's logging
module prints the huge --- Logging error --- blocks.

This keeps the useful part of #6755 - no logging setup as an import side
effect - but avoids retaining whichever stderr stream happened to be
active during the first CLI run.

Before

I include the output I'm seeing where I have two failing tests in
test_convert.py. See the amount of noise this generates - this also
hides the actual test failures under repeated logging-internal
tracebacks and captured debug logs.

Remote Changes:

use pathlib in tests: use only Path-based attributes on PathsMixin/TestHelper (#6847)

Part of #6807

• This change standardizes the test helper path API around
  pathlib.Path. Main shared helpers now use temp_path, lib_path, and
  import_path instead of older mixed names like temp_dir,
  temp_dir_path, libdir, and import_dir.

• Architecturally, path handling is pushed toward one clear model: use
  Path objects inside helpers and tests, and only encode to bytes at
  boundaries that still require it, like importer session setup.

• beets.dbcore.types also now accepts Path values for item.path,
  so code can pass Path objects directly without manual conversion.

• High-level impact: the test infrastructure becomes more consistent,
  path-related code gets easier to read, and there is less
  bytes/string/path conversion scattered across the suite. This is mostly
  a cleanup and API consistency change, not a behavior change.

typing: add types to beets.dbcore (#6820)

What changed

• This PR is mainly a typing pass over beets.dbcore, especially in
  db.py, query.py, sort.py, and types.py.
• The main architecture change is in db.py: model materialization is
  now centralized in Database._make_model(), while Results only
  handles lazy row iteration and uses a materializer callback.
• Reloading is also cleaner now: Model.get_fresh_from_db() goes
  through Database._reload(), which keeps database lookup logic in the
  database layer and preserves the model's concrete type.
• Along the way, a few runtime mismatches found by typing were corrected
  instead of just adjusting annotations.

Why

• The goal is to make the typed API match the real behavior of dbcore.
• This improves separation of responsibilities: querying and result
  iteration stay in Results, while row-to-model construction and reload
  behavior live in Database.

High-level impact

• dbcore has a clearer internal structure and a more explicit API
  surface.
• Type information is more accurate across queries, sorting, models, and
  field types, which should make future refactors safer.
• A few small correctness fixes are included:
  • DurationType.format() now always returns str.
• PathType.from_sql() only expands paths when the normalized value is
  actually bytes.
• Several __eq__ implementations now use explicit isinstance(...)
  checks.
• Reload behavior now has regression coverage in
  test/dbcore/test_db.py.
• Overall, this is a low-risk cleanup: mostly typing and API-shape
  improvements, with a few small behavior fixes discovered during the
  work.

typing: type beets.library (#6825)

• This PR finishes a broad typing pass across beets.library, mainly in
  beets/library/models.py and beets/library/library.py, and tightens a
  few related plugin and dbcore interfaces.

• Architecturally, the change makes the Library, Item, Album,
  query parsing, and template helper layers agree on clearer contracts:
  nullable values are explicit, collection and query return types are
  defined, and cross-layer APIs now use more precise types.

• The main behavioral surface is still the same, but several weak spots
  are now modeled directly in the code, such as optional albums on items,
  optional art paths, library-backed template memoization, and query
  objects flowing through Library._fetch().

• The PR also cleans up how template uniqueness helpers work by giving
  _memotable and related keys a stable shape, and by tightening the
  logic around album-aware formatting and disambiguation.

• A small architectural rename in dbcore changes Database._fetch()
  to Database.get_results(), which makes the lower-level database API
  clearer and avoids confusion with Library._fetch().

• High-level impact: better static type safety, clearer boundaries
  between database, library, model, and templating code, and less
  ambiguity for future refactors without intentionally changing
  user-facing behavior.

discogs: refactor _coalesce_tracks around more specific track types (#6818)

• beetsplug/discogs/types.py now models Discogs tracklist entries as
  distinct shapes: AudioTrack, IndexTrack, and HeadingTrack. This
  shifts the plugin from "guessing by position" to handling each entry
  by its declared type_.

• beetsplug/discogs/__init__.py refactors _coalesce_tracks() into
  smaller helpers for flat subtracks and index tracks. The normalization
  flow is now type-driven, which makes the rules for "one physical track"
  vs "many physical tracks" more explicit.

• beetsplug/discogs/states.py now advances track state only for real
  audio entries (type_ == "track"), so structural entries no longer
  affect track counting through indirect position checks.

• Tests now use dedicated Discogs track factories and add coverage for
  logical index tracks. This gives the refactor a clearer test model and
  protects the new coalescing behavior.

• High-level impact: Discogs imports should now treat headings, index
  containers, and subtracks more consistently, especially for releases
  where one displayed work contains multiple logical parts but maps to a
  single playable track.

This change is based on the following research (thanks, Codex!):

Discogs track coalescing

DiscogsPlugin._coalesce_tracks() handles three distinct notions all
called
"subtracks." This is the main source of its complexity.

Discogs distinguishes:

• track: an audio entry.
• index: a titled container whose sub_tracks are parts or movements.
• heading: descriptive text applying to following tracks.

That distinction is documented in the current
Discogs tracklisting
guidelines.
Positions such as 3.1, 3.2 or 3a, 3b separately indicate
multiple
musical pieces inside one physical track.

Observed input shapes

Case	API shape	Current result	Example
Normal track	type_="track", nonempty position	Passed through
Most releases
Flat virtual subtracks	Multiple top-level track entries with
1.1, 1.2 or 22a, 22b	Merged into a copy of the first track
This Is Not, [Eclectic Beatz
8](https://www.discogs.com/release/2885582)
Nested logical subtracks	index with nested children sharing one
physical position	Parent index becomes the physical track; children
discarded	[Defqon.1 Weekend
Festival](https://www.discogs.com/release/7168134)
Nested physical subtracks	index with children numbered as
independent tracks	Index discarded; children promoted	[Classical
Hollywood III](https://www.discogs.com/release/3647530)
Heading	heading, empty position, no sub_tracks	Passed through
as structural metadata	Defqon.1 CD headings
Ambiguous/nonstandard index	index with positions the regex cannot
classify	Usually promoted incorrectly as separate tracks	[King
Crimson - Lizard](https://www.discogs.com/release/1156598)

Flat virtual subtracks

This Is Not returns nine top-level entries:

{"type_": "track", "position": "1.1", "title": "Intro", "duration": "1:49"}
{"type_": "track", "position": "1.2", "title": "Untitled", "duration": "6:31"}
# ...
{"type_": "track", "position": "1.9", "title": "2 Bad ...", "duration": "10:18"}

There is no index container. _coalesce_tracks() detects the suffixes
and
_add_merged_subtracks() produces:

{
    "type_": "track",
    "position": "1.1",
    "title": "Intro / Untitled / ... / 2 Bad ...",
    "duration": "1:49",
    "artists": ["Unknown Artist"],
}

It copies all metadata from the first entry and only combines titles.
This
explains the incorrect duration and artist.

Eclectic Beatz 8 has the same flat shape:

{"type_": "track", "position": "22a", "title": "Amplifier", "artists": ["Fedde Le Grand"]}
{"type_": "track", "position": "22b", "title": "Autograph ...", "artists": ["Hatiras", "MC Flipside"]}

Those become one track, retaining only the first artist.

Nested logical subtracks

Defqon.1 contains:

{
    "type_": "index",
    "position": "",
    "title": "Eat This / God! What The Hell!",
    "duration": "3:06",
    "sub_tracks": [
        {"type_": "track", "position": "2-20A", "title": "Eat This"},
        {"type_": "track", "position": "2-20B", "title": "God! What The Hell!"},
    ],
}

Because 2-20A has a parsed subindex, the helper changes the parent to:

{
    "type_": "index",
    "position": "2-20",
    "title": "Eat This / God! What The Hell!",
    "duration": "3:06",
}

The children disappear. Downstream code treats this as audio solely
because
its position is now nonempty. It never checks that type_ remains
"index".

Nested physical subtracks

Classical Hollywood III contains index containers such as:

{
    "type_": "index",
    "position": "",
    "title": "Auld Lang Syne Variations For Piano Quartet",
    "sub_tracks": [
        {"type_": "track", "position": "1", "title": "Eine Kleine Nichtmusik ..."},
        {"type_": "track", "position": "2", "title": "L.V.B. - Adagio"},
        {"type_": "track", "position": "3", "title": "Chaconne ..."},
        {"type_": "track", "position": "4", "title": "Homage ..."},
    ],
}

Because position 1 has no subindex:

• the index container is removed;
• its children become top-level physical tracks;
• parent artists are copied to children missing artists;
• when index_tracks is enabled, the parent title prefixes every child
  title.

This behavior was added for
issue #2318 by
PR #2355.

Headings

Defqon.1 also contains:

{
    "type_": "heading",
    "position": "",
    "title": "CD2 ⚡ Mixed By Partyraiser",
    "duration": "",
}

This is not coalesced. It passes through, but TracklistState
subsequently
treats every positionless object as structural metadata without checking
type_.

The code therefore cannot distinguish:

position == "" and type_ == "heading"
position == "" and type_ == "index"

Worse, _add_merged_subtracks() identifies a parent using only:

tracklist and not tracklist[-1]["position"]

A heading can therefore theoretically be mistaken for an index parent.

History

• Issue #1543 reported
  flat
  positions such as 22a and 22b representing one CD track.
• PR #2222 added both flat
  and
  nested subtrack support. Its author explicitly noted that type_ might
  identify index tracks robustly, but avoided the larger refactor.
• Issue #2318
  demonstrated that
  nested sub_tracks can instead be independent physical tracks.
• PR #2355 added the current heuristic:
  • parsed child subindex means logical fragments of one physical track;
  • no parsed child subindex means independent physical tracks.
• That PR documented the heuristic as imperfect. Lizard, with Ba,
  Bb,
  Bc, and related positions, was already a known failure.

Test data does not match the API shapes

The current test helper always creates:

"type_": "track"

Consequently, test inputs such as:

_track("TRACK GROUP TITLE", sub_tracks=[...])

are not realistic. Real API data uses:

"type_": "index"

Likewise, test medium titles are manufactured as positionless track
objects
rather than heading or index objects.

Recommended direction

Before refactoring production code, introduce accurate input types and
factories:

TrackEntry = AudioTrack | IndexTrack | HeadingTrack

With approximate shapes:

class AudioTrack(TypedDict):
    type_: Literal["track"]
    position: str
    title: str
    duration: str
    artists: NotRequired[list[Artist]]


class IndexTrack(TypedDict):
    type_: Literal["index"]
    position: Literal[""]
    title: str
    duration: str
    sub_tracks: list[AudioTrack]
    artists: NotRequired[list[Artist]]


class HeadingTrack(TypedDict):
    type_: Literal["heading"]
    position: Literal[""]
    title: str
    duration: str

Then test using _track(), _index(), and _heading() factories.

The eventual normalization can dispatch structurally:

1. track without subindex: pass through.
2. Flat subindexed track group: apply the flat-fragment policy.
3. index: normalize its children as logical or physical.
4. heading: preserve as structural metadata.
5. Never infer an index merely from position == "".

This removes the most dangerous ambiguity while preserving the
positional
heuristic where Discogs genuinely requires it.

replaygain: add metaflac backend (#6800)

Fixes #1203.

The replaygain plugin can't compute ReplayGain when metaflac is the only
tool available. The existing backends (command, gstreamer, audiotools,
ffmpeg) each need something heavier installed, which doesn't work on
minimal setups like a NAS where those won't install. Issue #1203 asks
for a metaflac based option so FLAC users on those setups can still tag
ReplayGain.

This adds a metaflac backend for that case. It runs metaflac --add-replay-gain to compute the gain and reads the values back with
metaflac --show-tag. I modeled it on the existing CommandBackend
since both wrap an external tool. It only handles FLAC, skips other
formats, and shifts the gain to the configured targetlevel like the
other backends.

One limitation: metaflac scans a whole album in one pass, so the files
of an album need the same sample rate and channel layout.

Before, selecting the metaflac backend failed:

$ beet replaygain
UserError: Selected ReplayGain backend metaflac is not supported.

After, the backend works and the plugin tests pass:

$ python -m pytest test/plugins/test_replaygain.py
7 passed, 4 skipped

The 4 skipped are the Opus R128 cases, which don't apply to the metaflac
path.
