Lots of warnings in command line utility

Since version 3.6 the command line utility prints out quite a few of these warnings:

QVariant::load: unknown user type with name Ms::MuseScoreStyleType.

Is that a bug? Or my system configuration?

Probably leftover debug messages.
Do you have more context?

What version exactly and from where, on what operating system?

Interesting... none of that in the Windows version. These messages seem to come directly from Qt, not from MuseScore itself though, see https://github.com/qt/qtbase/blob/2f9a3352b25417845375c47382f6e5fe931c1…
Even more intersting: something like "MuseScoreStyleType" doesn't exist within the MuseScore source code.
Is this some plugin of your's maybe?

Workaround:
mscore -o test.pdf test.mscz > test.out 2>/dev/null

Only message we could be doing something about is that
ZoomBox::setLogicalZoom(): Formatting logical zoom level as 100% (rounded from 1.000000)
which is a qDebug() statement in the MuseScore code

No such warnings on Linux either.

kontrafuss

Without looking into the code – it's been a while since I've messed with Qt – but I think this warning comes from the QVariant constructor, or possibly from deserialization code. Could also be related to QML. The warnings do not appear if I use the command line tool to invoke the GUI, like so:

mscore test.mscz

Jojo-Schmitz

• Mar 10, 2021 - 11:35

See above for the exact location that message comes from

I too suspect some QML, probably a plugin

kontrafuss

• Mar 10, 2021 - 11:37

Nope, not plugins. I just wiped my plugins folder and did a restart. Same messages.

Jojo-Schmitz

• Mar 10, 2021 - 11:43

Some custom palettes?
Any of the plugins that come as part of MuseScore?

MuseScoreStyleType was used for the theme preference setting up to 3.5.2 and replaced by MuseScorePreferredStyleType and MuseScoreEffectiveStyleType for 3.6+ (see https://github.com/musescore/MuseScore/commit/beaf03cabf0f87537c10b5d6f… )

Thus these messages come from loading an old preferences file with a newer release and should disappear as soon as your preferences have been saved with the new version.

Jojo-Schmitz

• Mar 14, 2021 - 12:15

Ah, thanks for digging that up!

kontrafuss

• Mar 19, 2021 - 05:39

That makes sense, since these warnings started appearing in 3.6. However, I still haven't found out what I can do to stop them. What preference file is it you're talking about? I've been working with 3.6 for a while now, and my style files (mss) have been updated with 3.6. Or is this some other preference file?

Check MuseScore3.ini

kontrafuss

• Mar 19, 2021 - 06:40

I don't think I have an ini file. This is on a mac. I checked the preference file ~/Library/Preferences/org.musescore.MuseScore3.plist, but cannot see any suspicious entry. Also, should be up to date by now.

grep -r MuseScoreStyleType Library/Application\ Support/MuseScore/ doesn't give any results.

Jojo-Schmitz

• Mar 19, 2021 - 07:04

Indeed Macs don't have .ini files, it should be in ~/Library/Preferences/org.musescore.MuseScore3.plist, see https://musescore.org/en/handbook/3/revert-factory-settings#instruction…

Jojo-Schmitz

• Mar 19, 2021 - 07:08

You can try to see whether reverting MuseScore to factory settings gets rid of that debug message

kontrafuss

• Mar 19, 2021 - 07:48

I did mscore -F and that cleared the warnings. Still wondering what went wrong, though.

Thanks for help and support!

Jojo-Schmitz

• Mar 19, 2021 - 07:50

There got to have been a remnant of that old preference setting somewhere

I have done the Factory Reset (several times) and I am still getting this problem.

I am on Mac OS 11.5.1, MuseScore 3.6.2 (recently upgraded from 3.2)

$ /Applications/MuseScore\ 3.app/Contents/MacOS/mscore --version
dlopen error : dlopen(libjack.0.dylib, 1): no suitable image found.  Did find:
    .: not a file 
dlopen error : dlopen(/usr/local/lib/libjack.0.dylib, 1): image not found 
MuseScore3 3.6.2

Also, I do not know if it is relevant, but the plist file is pretty weird:

$ cat ~/Library/Preferences/org.musescore.MuseScore3.plist
bplist00?6

And it's even weirder if I try to edit it directly in vi (see attached).

Is it supposed to look like that?
I tried deleting it and letting MuseScore recreate it on load. Same result.

That "b" in the "bplist" marker at the start of the file indicates that it is a binary format plist file; so yes, opening it straight up with a text editor won't make much sense to most.

See the plutil man page on how to convert between the binary format and an xml or JSON format.
