macOS filesystem metadata files included on import

[maartenbrakkee]

Update 25-02-2022 15:22:

Describe the bug/issue
MacOS filesystem metadata files are included on import. These files start with ._. Because the files end with the original file's extension, Darktable sees them as images and imports them. However, in Darktable they can't be opened and give an error.

Original report:

Describe the bug/issue
TIF files created by Epson Stylus SX420W/SX425 cannot be displayed in Darktable. Photos do work in macOS file explorer.

Magick: Not a TIFF or MDI file, bad magic number 1280 (0x500). (/Volumes/Elements_02/Foto/2000 Divers/._00 Divers 062.tif).
[GraphicsMagick_open] image `._00 Divers 062.tif' not found
[dt_imageio_export_with_flags] mipmap allocation for `unused' failed
[dt_imageio_export_with_flags] mipmap allocation for `unused' failed
[dt_imageio_export_with_flags] mipmap allocation for `unused' failed
[rawspeed] (._00 Divers 062.tif) virtual std::unique_ptr<RawDecoder> rawspeed::RawParser::getDecoder(const rawspeed::CameraMetaData *), line 91: No decoder found. Sorry.

To Reproduce
Import the attached image.

Expected behavior
Show the image.

Weird, it's trying to open ._00 Divers 062.tif (some macOS temporary artifact?) instead of the real 00 Divers 062.tif...

Can you try copying the actual file and importing from another folder? Or removing those temporary files and re-importing?

Edit: The attached file works just fine w/ dt 3.8.1 on Windows btw...

It seems that you are correct. The ._-files seem to be related to the macOS file explorer. On my first import, I didn't see the files as I imported a lot of images recursively.

However, importing the ._ files is still unwanted. Anything that can be done about it? I'm importing a lot of folders, importing them one by one and deselecting the ._-files would take a lot of time.

Dunno, not a Mac user/developer...

In any case, now you can and should change the title of the issue to be more accurate so it can hopefully attract appropriate attention.

I guess it makes sense not to import hidden files (at least by default).

The import filter lua framework is meant to deal with such issues, see https://darktable-org.github.io/luadocs/lua.scripts.manual/scripts/official/import_filter_manager/.
