Summary0014354: Wi-Fi Sync: Editing tracks causes them to be deleted from Playlists / Playlists updated even when not changed
DescriptionI'm able to replicate this using MMW / MMA on an S5mini (Android 6) using Wi-Fi sync.

Repro steps:
1 Sync PlaylistA
2 Add 'Metal Skin' (by Sam Roberts Band, Album: Lo-Fantasy) to PlaylistA
3 Resync
-->MMA displays the track as expect as part of PlaylistA
4 Edit the Album name (for all tracks on the album) to Lo-Fantasy1
5 Resync
--> Track is removed from the playlist! (resyncing fails to get it to re-appear)

TagsNo tags attached.
Fixed in build729

I can't replicate with MMW / MMA
Wasn't the PlaylistA an auto-playlist defining album as a rule?

So I can't figure out how to replicate the problem--even though it was occurring consistently yesterday. :-(

The one strange thing that I'm noticing today, though, when testing on that device is that every time I sync (even without changing the playlist or editng tracks) MMA indicates 'Updated x playlist(s) from server'

The trigger seems to be to edit the contents of the playlist once--subsequently, every sync results in the 'Updated x playlist(s) from server' (where x depends on the number of playlists that have been edited).

MMW log posted to ftp.

Upon retesting, I can confirm that:
- After the initial sync of New Downloads, subsequent syncs don't cause the playlist to update.
- If New Downloads is modified by adding a track to it (in MMW), subsequent Wi-Fi syncs always result in 'Updated playlists from server'.
- An examination of the playlist file (by renaming it to .txt on the device) shows that it actually _does_ get modified correctly on sync when the track is first added to the playlist (which is surprising since the fact that MMA tries to update it on subsequent syncs would imply that it isn't correctly updated).

So the playlist New Donwloads is still updated on each subsequent sync ?

I retested this and found that the although the playlist was re-downloading, it never actually updated (neither in MMA nor in the M3U file), and in fact, in some cases, was deleted entirely as originally reported above (although I could have sworn that in earlier tests, the playlist did update in MMA):

1 Deleted playlists from MMA and m3u files from device
2 Initiated sync (of New Downloads playlist)
--> 'Downloaded 1 playlist' (5:46:43)

3 Wi-Fi Sync
--> 'Everything is in sync' (5:46:43-2)

4 In MMW, add 'Dreadlock Holiday' to the playlist
5 Wi-Fi Sync
File converts, 'Downloaded 1 track', 'Updated 1 playlist from server' (5:55:11)
BUT, the playlist didn't get updated with the new track in MMA (though the track did copy)! (afaik, this bug did not occur previously)

6 Wi-Fi Sync
-->'Updated 1 playlist from server' (5:46:43)
But the playlist still didn't get updated with the new track in MMA

7 In MMW, deleted 'Dreadlock Holiday' from the playlist
8 Wi-Fi Sync
'Updated 1 playlist from server'
BUT, the playlist didn't get updated with the new track in MMA (though the track did delete)!

9 USB Sync
--> No changes, except for the creation of a 0B New Downloads.pla file in /InternalMemory/Playlists

10 In MMW, add 'Shapeshifters' to the playlist
11 Wi-Fi sync
File converts, 'Downloaded 1 track', 'Updated 1 playlist from server' (6:15:29)
BUT, the playlist deleted from MMA! (6:15:29)
Note: this is the bug that was _originally_ reported at 0014354

12 Wi-Fi sync
--> Same as step 11!! i.e. the playlist is still missing :-(

The original issues seem to be fixed. However, there are now some other problems (debug log posted to ftp):

Bug 3): See line 6246 (and at least 2 sync operations prior to that): after removing and adding a track to a playlist, every Wi-Fi sync operation --> "Updated 1 track(s)" message!

Bug 4): Playlist edits in MMA don't sync to MMW (I thought that this worked previously, but perhaps I'm mistaken ?). e.g.:
1 Remove 2 tracks (under your thumb, London is bangin...) from 'New Downloads' playlist in MMA.
2 Initiate Wi-Fi sync (MMW line 6868)
New Downloads Playlist in MMA is missing the two tracks, but they're not deleted from the device (despite that 'delete unselected...' is enabled), while the same playlist in MMW has the missing 2 tracks!

Bug 3) MMA log is needed to find why "Updated 1 track" appeared

Bug 4) based on the MMW log the bidirectional sync was disabled so the playlist wasn't synced MMA -> MMW (as expected)

I've just replicated the problem twice and generated a log after each sync:

Bug 3) The artwork is missing in MMW. Each syncs, it tries to update metadata - it means it tries to download the artwork but MMW returns HTTP404. We do not have error message for this. I know that MMW DB contains deadlinks because it is not able to verify it. That is why it shows "Updated 1 track(s)"

re bug 3) As discussed offline: Fix is needed on MMA side, MMA shouldn't try to re-download artwork deadlinks on next sync.

As described at 0014358 I'm still occasionally seeing 'Updated 1 track' in some cases, but it is only occasionally and it seems to be related to making changes in playlists and/or the auto-sync list.

So I would consider the fix to this issue to be verified.

3) it is fixed in build 729. The remaining issue in 0014358 is about playlists, not tracks. That is different. This issue with artwork failure was already fixed.
