Update a folder works. Several times.

But after reboot Update a folder gives the "Library update is already in progress." message.

Does this present new information?

I don't see anything suspicious in the log.

I'm not able to reproduce the issue but here's some log output from one of my test collections for successful "Update this folder" and "Update library".

Your log should look similar if the library updates are completing successfully. Note that the Thumbnail Generator and MPD database update run parallel to one another so one may complete before the other and thats fine.

Another troubleshooting approach is to look at the GLOBAL flags in the front-end (WebUI) that determine whether it thinks a Library update is still running.

- Open your Browsers Javascript console
- At the prompt type in GLOBAL.libLoading; <return> and GLOBAL.libRendered; <return>
- They will either be true or false depending on whether the front-end thinks the Library update and Library rendering in the WebUI are complete.

The function below in file /var/www/js/playerlib.js is responsible for displaying "Library update in progress".

Code:
function submitLibraryUpdate (path = '') {

    if (GLOBAL.libLoading == false) {

        GLOBAL.libLoading = true;

        // DEBUG:

        //console.log('submitLibraryUpdate(): GLOBAL.libLoading: ' + GLOBAL.libLoading);

        GLOBAL.libRendered = false;

        $.getJSON('command/music-library.php?cmd=update_library', {'path': path}, function(data) {

            //console.log(data);

        });

        notify(NOTIFY_TITLE_INFO, 'update_library', (path == '' ? '' : '<br>' + path));

    }

    else {

        notify(NOTIFY_TITLE_ALERT, 'library_updating');

    }

}

The function submits the command 'update_library' and and optional path to /var/www/command/music-library.php. This script in turn submits the 'update_library' job to /var/www/daemon/worker.php which starts MPD database update and thumbnail generator. If those complete successfully log entries are written to the moode log and the GlOBAL flags are set appropriately.

If this code in the function never returns or bombs then the GLOBAL flags prolly won't be set correctly. I'm not able to get this to fail in my environment so I have no insights.

Code:
       $.getJSON('command/music-library.php?cmd=update_library', {'path': path}, function(data) {

            //console.log(data);

        });

Food for thought :-)

And it returns flags like this

Code:
GLOBAL.libLoading;

true

GLOBAL.libRendered;

false

Is it possible to somehow reset the GLOBAL.libLoading flag?

I have a guess that in version 8 the Refresh command from the main menu reset these flags

3. take note of the pattern of those suspicious folders names, then, with a very powerful Linux tool by the name of "find" you can scan (and get rid of) all those nasties is a matter of seconds; like:

find <root folder of your library> -iname "file/folder pattern" -exec rm -rf "{}" \;

If you just want to see how many they are, but take no immediate action, just end the command at "file/folder pattern" and you are free to go.
But I don't know what to look for, what sample

It is a music library containing music you acquired, any thing that isn't music or related (cover images, folders, etc) can go. You know what should be in there, it's your library.

In my Browsers Javascript console immediately shows an error -

Code:
Uncaught TypeError: (e.album_artist || e.artist).toLowerCase is not a function at keyAlbum (scripts-library.js:506:81) at scripts-library.js:248:23 at Array.map (<anonymous>) at groupLib (scripts-library.js:246:21) at renderLibrary (scripts-library.js:128:2) at Object.success (scripts-library.js:111:3) at u (jquery-1.8.2.js:974:30) at Object.fireWith [as resolveWith] (jquery-1.8.2.js:1082:7) at N (jquery-1.8.2.js:7788:14) at XMLHttpRequest.n (jquery-1.8.2.js:8500:8)

And it returns flags like this

Code:
GLOBAL.libLoading; true GLOBAL.libRendered; false

Is it possible to somehow reset the GLOBAL.libLoading flag?

I have a guess that in version 8 the Refresh command from the main menu reset these flags

Menu > Refresh is the same as a Browser reload or refresh. Theres nothing special about it.

That specific Javascript error at that line in the function could happen with poorly tagged music files that are missing the basic tags like Artist, Title, Album, Track etc, or the files could have some sort of other metadata corruption. If the script blows up the globals and all other state variables won't be set correctly. The only way to prevent the error is to fix the data in the music files.

Generally moode is not the best player software for untagged or sparsely tagged collections. Something like PiCorePlayer (LMS/Squeezelite) I think has more exception handling for things like missing tags or corrupt files but you might be able to work around the data triggered error in moode by setting Prefs > Library > Album key to Folder path or Folder path@AlbumID.

Using the script, I deleted all unnecessary folders and files from the disk.
I left only music(dsf, flac, wav) and picture files(jpg, png).
I regenerated the library - all useless. The problem remained.

How to find this damaged album?

I am not aware of a program which can scan for all possible music tracks, no matter their encoding and container (e.g., file type), verify their metadata, and report out all files which are problematic. If anyone else is, I'd like to hear about it.

I'm not a JavaScript expert but I believe the specific error you reported means either an album_artist tag or an artist tag in some file did not contain a string value. The function .toLowerCase requires a string input, so it failed. I suppose a savvy JS coder could modify the routine to identify the file it was working from, but that person certainly isn't me.

Since you've now "cleaned" your library of extraneous files, you could try using the .mpdignore directive to narrow down the list of suspect files.

1. clear the MPD and related databases (I'm not sure what is the best way to do this.)

2. at the highest-level directory in your library collection, place a text file named .mpdignore. In it, place the text lines

Code:
*.dsd

*.wav

This means that MPD should scan your entire library for only .flac files. (I chose them first only because I like their tagging scheme best).

3. use the usual moOde webUI methods to update your library.

4. does this succeed in all the ways you expect?
- if yes, then go to next step.
- if not, you at least now know you have one or more FLAC files to fix. Go fix* them and then repeat.

5. repeat the above, but this time using a .mpdignore file containing

Code:
*.flac

*.wav

6. same as 3.

7. Same as 4. except now you know you have one or more .dsd files to fix.

8. Do it all again but this time with a .mpdignore file containing

Code:
*.dsd

*.flac

You can guess where this is heading. As an aside, I dislike WAV files the most because of their lack of prescriptive metadata tagging. People do all sorts of wild things to add metadata to them.

In summary, yes, this is tedious, but with a huge un-proctored collection of putative music files, you have to start somewhere.

Obviously, the same approach could be taken at a subdirectory level but not knowing your file organization (and I don't really want to!!!) I don't know what to suggest.

All this is just my 2 cents worth.

Good hunting.

Regards,
Kent

*''fix" means different things for different file types. I suppose you could turn programs like mp3tag, easytag, or kid3 loose on them but I prefer using FLAC-specific command-line tools when dealing with FLAC files, and so forth.

Thank you very much, I will definitely try it on Monday

Just think though, how much more intimately you will know your music collection after this, how much more pleasurable it will be knowing it is clean and nicely tagged. You might even start to enjoy views other than the folder view Smile

@Tim Curtis
Couldn't it be helpful to have (e.album_artist || e.artist || "missing tags") solve the issue for those "poorly tagged files"? As IMHO both tags are missing, resulting in undefined.toLowerCase() which of course does not exist...
