This slightly speeds up the queries and there's a nice side-effect where
`singleton:1` and `singleton:0` now work fine!
This is ultimately building towards replacing as many python-only
queries with SQL equivalents.
- Remove initial comment around playlist entry condition (which is better
suited for user docs anyway, and stated there already)
- Add explanation above the items_paths playlist contents creation list
comprehension.
- M3UFile.read() method reads in rb mode.
- M3UFile.read() method handles removal of (platform specific) line endings.
- Playlist contents and EXTM3U header is handled as bytes.
- Fix test_playlist*read* tests to encode playlist UTF-8 assert strings to
bytes using bytestring_path() before comparision.
- Fixture playlist_windows.m3u8 is now actually Windows formatted (\r\n + BOM)
Make sure we stay with the beets standard of handling everything internally as
bytes.
- M3UFile.write() method writes in wb mode.
- Playlist contents and EXTM3U header is handled as bytes.
- item.destination() gives us unicode string paths, we tranlate to bytes
using util.bytestring_path().
- Fix test_playlist*write* tests to encode UTF-8 assert strings as bytes using
bytestring_path() before comparision.
The M3UFile.write() method now creates potential parent directories in a passed
playlist path.
util.mkdirall() handles errors nicely already and would exit the mainprogram
before potential subsequent failures could happen (it raises
util.FilesystemError).
Add test_playlist_write_and_read_unicode_windows: Writes 2 media file
paths containing unicode characters, reads them in using M3UFile class
again and tests if the contents is correct.
- Add and Exception class called EmptyPlaylistError ought to be raised
when playlists without files are loaded or saved.
- Add a test for it in test_m3ufile
- Fix media_files vs. media_list attribute name.
- Move the creation of the playlist file to the very end, right after
self._parallel_convert, in the convert plugin's main function.
- In the test code, the destination directory is created when the
conversion happens, thus this fixes test_playlist and doesn't hurt the
feature - The playlist creation can as well be the very last step in
the process.
