Title: Undo?
Post by: varoomba on December 09, 2010, 12:08:38 AM
I am loving Music Bee.  A few times my heart has stopped for a few seconds when I thought I accidentally selected my whole music library rather than just a speific album and changed the genere.  That would be REALLY bad since I've spent a huge amount of time categorizing my music. 

So the good thing is that I haven't done this.  My concern, however, is that I don't see an undo function - so I suspect that one of these days I will do something globally - or even to 50 or 60 albums that will wipe out a ton of work and be unfixable. 

I could back up my music library at intervals and then restore from last backup point...  or is there an undo function that I'm just missing?

Thanks,

Keith

Currently there's "Undo changes" feature in tag editor. But once the file is saved, there's no way to undo the changes and go back to the previous state. Would be nice if that's possible.

Heads up... one sec... an undo feature across the board, although sounding nice, is actually a challenging development. Not to mention a resource hog depending on the type of undos - think about an infinite buffer for undoing artworks - ewwww!

Therefore, perhaps a slight shift to an out of the box thinking is more suited to help with the OPs train of thought.

So, perhaps something like,

If operation about to be committed will affect more than 20 tracks, then aggressively warn the user.

Would be far far quicker for Steven to implement.

Mp3tag says it supports unlimited undo feature. How does that work? Anybody familiar to that?

In terms of resource, there are two ways...
1) RAM
2) HDD/SDD etc. storage

If you change 100,000 photos in one operation, that is quite some resource penalty.

Often, a hybrid of both are implemented. So after say x number of operations, the rest are saved to a more permanent storage e.g. db.

mp3tag is a tool that is loaded, used and then closed, therefore, the used resource is quickly recovered. Conversely, MB is often minimised, therefore, such a hit on resource is a certain consideration. Saying that, I am not likely to change 100,000 photos, but I am thinking of the community use rather than my own.

There are many +1s so @Steven if you do implement this feature, can you add a configurable limit on the impact this has on resources (say a max of 10 undo steps by default) Then watch people later complain and wonder how MB is using 1 Gb ram.

Post by: redwing on September 15, 2013, 06:28:35 PM
A compromising way would be:

1. Exclude artwork completely from undo feature: still better than not having undo feature at all

2. Resize artwork universally to, say, 100x100, in db: still better than having nothing since you get at least a clue to what to search

3. Give an option to include/exclude artwork and configure resizing dimensions for undo

I don't want to be warned politely when I'm editing tags, let alone aggressively. I'd hate this to become another pop-up dialog that gets inflicted every time when it's only needed one time in a million. The "Tags have changed. Do you want to save changes?" message is bad enough.

mp3tag is a tool that is loaded, used and then closed, therefore, the used resource is quickly recovered.
Not on my computer. It's almost always open. And I've been using it for the last three hours and it's still only using 15MB of RAM.

...if you do implement this feature, can you add a configurable limit on the impact this has on resources (say a max of 10 undo steps by default)
I think one level of undo would be enough. It's only to recover from a single "Whoops!" moment that affects a lot of files at once, as opposed to editing documents where you're always making incremental changes.

3. Give an option to include/exclude artwork and configure resizing dimensions for undo
For an undo function, that doesn't sound very useful. "Undo" should completely revert changes files to their previous state or not at all. I can't think of a single other program that implements a partial undo like that. It feels like lying to the user.

-edit-
As noted below, it seems Mp3tag doesn't undo changes to artwork. I feel lied to!
Title: Re: Undo?
Post by: Zak on September 15, 2013, 08:44:28 PM
Just tried a few things in Mp3tag and realised its undo feature actually doesn't support changes to artwork, which explains why it can offer unlimited undo but still retain a small memory footprint.

When it says unlimited, does that mean unlimited number of changes during one instance of program running from opening and closing down?
Title: Re: Undo?
Post by: Zak on September 15, 2013, 09:11:39 PM
I don't actually know if it is unlimited - I was just going by what you said earlier.  :P

I've shutdown my computer so can't check, but I'm sure it doesn't work between application sessions.


Title: Re: Undo?
Post by: redwing on September 15, 2013, 09:15:08 PM
Yeah, I was just wondering if it records every tag changes done by the app somewhere. Can't be, right? Has to be during each session.

<Edit>
But then, this is not a good choice. If you close down the app, there's no way to go back even if that's the last change you made. Regardless of the maximum supported number of tag changes, MB should support, if this gets implemented, undoing changes done during previous sessions.
Title: Re: Undo?
Post by: Steven on September 15, 2013, 10:21:35 PM
if i was to do this extra RAM memory being used wouldnt be a problem as it would cache the changes to disc.
I know this is a very popular request as it has been asked before but the reason it hasnt been implemented is i felt it would be quite a bit of effort to implement and test. I will probably do this time around though.
Perhaps only 1 undo for the most recent edit action only would suffice? - that would keep the UI simple
Title: Re: Undo?
Post by: redwing on September 15, 2013, 10:26:25 PM
That'be wonderful!

What about artwork? For one undo, can it support undoing full artwork regardless of track numbers, or what?

Great news, thanks!  I would really like it if Undo could include any playlist changes and soft deletes, but if that's too complicated I'll survive.  I haven't felt the need for undo very often, but usually it was over something like that.

Edit: Now that I think about it, accidentally loving/banning groups of tracks has been an issue for me.  I once accidentally banned my entire library and had to go through fixing it track by track.

What? You can adjust them with a single click from main panel. Add the field to main panel, select files, click for love, shift-click for ban over the icon.

Then go through re-banning each of the tracks that were banned in the first place, I guess...
Title: Re: Undo?
Post by: redwing on September 16, 2013, 07:34:26 PM
Sort by the field, select tracks with love(or ban), and a single click deletes the value from all selected tracks.
Title: Re: Undo?
Post by: psychoadept on September 16, 2013, 11:37:45 PM
The problem was that I had the field displayed in the main panel and accidentally selected all before I banned the track I was trying to ban (actually, it's coming back to me that it was just everything down to the track I was working on, because MB has a tendency to grab everything from the top down when I shift-click).  Then I had to try to remember which tracks I had loved and which I hadn't.  At least I wasn't connected to last.fm.
Title: Re: Undo?
Post by: redwing on September 16, 2013, 11:55:53 PM
Right, now I got what you meant. Then modified date would be the same too for all files. Can't think of any way to recover that aside from this requested undo feature.
Title: Re: Undo?
Post by: Steven on September 28, 2013, 09:34:55 PM
this has the Tag Undo functionality (Edit/ Undo/ File Tags) - it undoes tag & artwork changes but not rating changes

i did a lot of testing to make sure it was working, so could you give me a few more details eg. how you did the editing, how you verified it wasnt working?

edit:
trying again using the tag editor then undoing title and album restore as expected. However if the song is playing it doesnt refresh the player control panel - the file is still restored
Title: Re: Undo?
Post by: psychoadept on September 29, 2013, 08:37:59 AM
It works for me!  The only issue I see so far is that when I have the tag editor in the main panel, save a change and then undo it, the contents of the tag editor don't go back until I refresh or rescan the file.

I trust it will be possible to assign this to a hotkey once it's been tested for a while?  (Is there a hotkey for saving changes in the tag editor?  If not, that would be awfully nice, too.)

It doesn't sound like you're doing anything different from me.  I tried it both ways, too, just to be sure.  Hmm.  Just trying to think what else might be different.  Node, view...?

before i do that can you confirm by re-editing the file and checking with the tag inspector that the tags really are not restored? I am having trouble seeing how it could not work other than a display bug perhaps
Title: Re: Undo?
Post by: redwing on September 29, 2013, 09:38:59 AM
Confirmed with several tests after the tag was edited (changed) and after running undo (no changes).
Title: Re: Undo?
Post by: redwing on September 29, 2013, 09:44:21 AM
BTW this is what I see from the menu UI.

- "Edit - No files"
- Edited one file. Now it says "Edit - 1 file"
- Run undo, no changes in the tag, and it still says "Edit - 1 file"
- Once again running undo, no changes in the tag, and now it says "Edit - No files"

Title: Re: Undo?
Post by: redwing on September 29, 2013, 10:57:09 AM
Look at this.

I changed "Someone like You" to "Someone like You You." But it's logged as follows.

9/29/2013 10:50:12 AM - E:\Music Files\Pop\A\Adele\21\11 Someone like You.mp3,save title=Someone like You

At this point, when looked from mp3tag, the filename is already "Someone like You You.mp3", but MB logged wrong info.

Now doing undo.

9/29/2013 10:50:47 AM - undo batch count=1
9/29/2013 10:50:47 AM - E:\Music Files\Pop\A\Adele\21\11 Someone like You.mp3,current title=
9/29/2013 10:50:47 AM - E:\Music Files\Pop\A\Adele\21\11 Someone like You.mp3,restoring title=Someone like You
9/29/2013 10:50:47 AM - E:\Music Files\Pop\A\Adele\21\11 Someone like You.mp3,restored title=Someone like You
9/29/2013 10:50:47 AM - saving 1
9/29/2013 10:50:47 AM - saved

No changes in title, it's still "Someone like You You."

Now I edited the title to "Someone like You"

It's logged as follows:
9/29/2013 10:51:11 AM - E:\Music Files\Pop\A\Adele\21\11 Someone like You You.mp3,save title=Someone like You You

So it's always one step behind.

Title: Re: Undo?
Post by: Steven on September 29, 2013, 11:15:20 AM
ok, so you have your library auto-organised, so the filename changes because the title has changed.
If you do run the new debug version from above that could confirm it but it sounds a likely reason

Title: Re: Undo?
Post by: redwing on September 29, 2013, 01:35:32 PM
You're right. Some fields were changed but now I remember it said updated with error. Tried again with the fully updated file, and undoing it worked like a charm. Thanks!

<edit> I thought about that, and probably that's the moment the user really needs undo when auto-tag ended up with partial updating and errors. If that can't be supported, that's fine. But please have a look.
Title: Re: Undo?
Post by: Steven on September 29, 2013, 02:16:43 PM
any files that have been updated, even if it updated one file only and then the auto-tag operation failed, you should still be able to undo the changes. The undo list updates at the same time as when a file is updated. I would expect in your test none of the files were updated in that case.
I have updated the link so it excludes auto-tag operations with no updates.
Title: Re: Undo?
Post by: redwing on September 29, 2013, 03:13:50 PM
I would expect in your test none of the files were updated in that case.

Did some more tests, and, you're right, the file was not updated.

When auto-tag by track ended up with a message "Auto-tag completed with errors," often it updates some field only for main panel and/or tag editor. But tag inspector shows that's not a real value. Select file> right-click> Send to> File Rescan reverts it to the previous, real value for main panel and/or tag editor. Is this a bug?

If I run undo with the fake value displayed, MB says the file is no longer existent. If I remove the dead link, a right one shows up. So undo is working fine even in such cases.

i can see how the file is only updated in memory would happen and i need to fix that. It would be helpful if you are able to let me know the artist, title and album in question the next time you get some sort of error with the autotag so i can also fix that specfic error

Simply I did that with Adele's tracks after editing title to something else and running Auto-tag by track.

i cant reproduce any musicbrainz error that you got but i have changed it so it only updates the cache when the entire auto-tag for a file is sucessfully complete. Its in the next v2.2 update
If you do get errors in the auto-tag, it longs some more info in the error log to help me solve that

actually would you mind running this version, and if you do get auto-tag errors, let me know the "releaseId" that is now included in the error log

Undo is currently not working for love/ban changes.  Can that be included?

And if I may have a wish too, Rating and Album rating: It's so easy to change both accidentally, and especially if you'd like to change the album rating after having rated all songs individually but hit instead the individual ratings... 10 to 20 ratings lost within 1/10sec, happend more than once...
