The generic test harness now uses a temporary directory for beets' various
files as well as $HOME. As one packager pointed out, there were various test
failures when $HOME did not exist. This is no longer the case.
* util.prune_dirs modified to accept glob patterns as clutter to determine emptiness.
* config option, 'clutter' (a list of filenames/glob patterns)
* ImportTask.prune passes this option's value to prune_dirs.
For example, catalogue numbers like "[REACT217]". This shouldn't bypass the
nested multi-disc detection and automatically include all subdirs.
Do nested multi-disc detection first, so that `collapse_pat` is only set for
flattened albums, and we can skip the ancestry check on subsequent folders.
- Remove "part", "volume", "vol." multi-disc markers. These are often
part of album titles, and not necessarily indicative of a multi-disc
album. Only look for "CD X" and "disc X" (case insensitive), ignoring
white space and other non-word characters.
- Don't only expect each disc to be in a subdirectory of a common parent
directory, with all siblings belonging to the same release. Also match
any consecutive siblings (even when the parent contains other albums)
that are named with the same prefix and multi-disc marker.
- The `albums_in_dir(path)` function now always yields a list of paths
along with each list of items. `ItemTask.path` is now always a list of
paths.
- The `displayable_path(path)` function now accepts a list of paths, and
will join them with "; " by default. This can be changed with the
`separator` argument.
- The `sorted_walk()` function now does a case insensitive sort on
directories, but still returns case sensitive results. This allows
better multi-disc album detection.
- The `art_for_album()` function now takes a list of paths as its second
argument, instead of a single path.
The changes introduced in rc1 caused paths to be syspath-ified before they were
passed to os.path.abspath. The magic prefix caused them to be interpreted as
absolute paths even if they were relative. The fix is, in this *isolated*
case, to use Unicode but prefix-free paths in calls to the os.path.* functions.
Those functions need to act on Unicode objects but seem to be purely syntactic
-- nothing is tripped up by using long filenames without the magic prefix.
These tests were written when I knew almost nothing about Python and even less
about unittest. The class-generating magic never worked with nose for a crazy
reason I won't get into here. This has a bit more copypasta but the workings
are more obvious and we no longer generate enormous numbers of independent
tests. There should be a more representative number of dots in the test runner
output now.
