Color label not written to sidecars

[rekcodocker]

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

I just labeled 700+ files with star ratings and color labels.
Now I find DT did not write the color label to a single file.
I don't know how to reproduce

Steps to reproduce

Go to light table
Color label an image

XMP file has a line "xmp:Label="NoColor" " Which is incorrect because it does have a color.

Close and re-open DT.
The image has the correct color label but it's not in the sidecar file.
The rating is in the sidecar.

Expected behavior

Write the correct color label to the sidecar

Is you sidecar writing set to after edit?

[rekcodocker]

Is you sidecar writing set to after edit?

Yes it is set to 'after edit'
It stores the star-rating in the xmp file, as well as the edit. But it does not write the color label.

I ran into the problem when I re-imported files which were edited before but are not in my database. This information is lost while other info (the edit, star rating) is maintained.

Cannot reproduce:

   <darktable:colorlabels>
    <rdf:Seq>
     <rdf:li>1</rdf:li>
     <rdf:li>3</rdf:li>
    </rdf:Seq>
   </darktable:colorlabels>

Note that the color labels are not written in xmp:Label but in darktable:colorlabels as we need a list for supporting multiple labels on the same image.

Ah so they're in a different spot in the XMP?
This is what happened:

I had a typo in a directory name.
I deleted the files from DT knowing the edits would be preserved in the XMP.
I then renamed the directory outside of DT
Then I reimported the lot.

That is when the color label was lost.

[rekcodocker]

I can reproduce it now.
I see it's lost on importing xmp files.

1. I assign a color label to an image.
2. I remove it from DT (not from disk)
3. I re-import it again.
   The color label is lost on imoprt.

I have attached detailed XMP files so you can see it getting lost from file 6 to 7. The color label starts at line 99.

@rekcodocker : Still cannot reproduce with the scenario above. Question, do you have a Lr sidecar file next to the image?
