Bug ID: 422015 Summary: Canon THM files (and likely others) are ignored by Sidecar management unless named very specifically Product: digikam Version: 7.0.0 Platform: Compiled Sources OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: Metadata-Sidecar Assignee: digikam-bugs-n...@kde.org Reporter: griffiths_a...@icloud.com Target Milestone: --- SUMMARY Tested in 7.0.0-rc3, compiled as Arch AUR 'digikam-git' http://commits.kde.org/digikam/2a389849c15fb0fd5257c823e58e84822c34842e I specified .THM files as a sidecar in Configure/Metadata/Sidecars. When I moved the main photo between albums I find that the THM file does not travel like the xmp or pp3 files do (checked on command line). As the original extensions are upper case I specified it as upper case, but find on-rechecking the configure dialog has made it lower case. So I thought maybe it ignored them thru case sensitivity. So I renamed the extension of my test file from .THM to .thm (matching the sidecar list), but I find that it is still ignored. I noticed earlier that switching on commercial compatibility changes the filename of new sidecars to e.g. CRW_0930.CRW.xmp so I have tested that as below with the THM also, and found that Digikam recognises it and moves it, but in this case compatibility was still switched off. This makes me question what compatibility is doing? I've seen https://bugs.kde.org/show_bug.cgi?id=193232 STEPS TO REPRODUCE 1. Add THM as sidecar extension. Commercial compatibility = OFF. Note that the dialog has changed THM to thm. Entered 'pp3 THM'. Changed to 'pp3 thm' 2. Import an album, 'Test THM 1', of Canon CRW xmp and THM. File modification dates are irrelevant for the CRW and THM, the original photos were taken in 2005.

One last test to see if xmp file moves are case-insensitive. Rename THM to thm, xmp to XMP. XMP metadata is no longer visible in Digikam (first clue to how this ends..).

OBSERVED RESULT THM files do not accompany main file when moved, even though they're specified in sidecar list. This is for 2 reasons: 1. When entering THM in sidecar list, Digikam changes case to thm. The Sidecar list is case-sensitive. This ignores all my THM files. 2. Regardless of commercial compatibility setting, only THM files named as e.g. CRW_NNNN.CRW.thm are recognised, and moved. This appears not to be that case with existing xmp files. EXPECTED RESULT 1. THM files should accompany main file when moved, as they are specified in sidecar list. Sidecar list should not translate upper to lower case, as that is an assumption, and does not match the users data. As an aside, I entered 'pp3 thm THM' as my sidecar list, and when checked it, THM was removed giving 'pp3 thm'. 2. Sidecar files should be recognised in all cases, as there should be no assumptions on the filenaming of the user's data, which could come from many sources. 3. The commercial software compatibility naming should not apply to non xmp files. They originate in the chain well before the DAM. I should not need to rename files away from the camera standard.
