I’m on a Mac and they don’t always behave as you would expect coming
from a Linux system. For instance, Bas’ tar command doesn’t fly with
my particular brand of tar:

tar: Option -a is not permitted in mode -t
-a is likely a GNU tar specific option. I'm remember cursing grep on
Solaris not supporting -A/-B/-C back in the day.
`tar tzvf proj-data-1.17RC2.tar.gz` does work on Mac, but it ignores the
._ files, they are also not present after unpacking the archive.
Unpacking the file surprisingly doesn’t reveal anything either. You’d
think this sort of thing was easy to figure out but here we are. I am
not the release manager you deserve but the one you got. Sorry.
Apparently the ._ files are an Mac thing for extended attributes:
https://unix.stackexchange.com/questions/282055/a-lot-of-files-inside-a-tar
The attributes in question:
% xattr /tmp/proj-data/*_README.txt
/tmp/proj-data/fr_ign_README.txt:
com.apple.metadata:kMDItemKeyphraseConfidences
/tmp/proj-data/fr_ign_README.txt: com.apple.metadata:kMDItemKeyphraseLabels
/tmp/proj-data/fr_ign_README.txt: com.apple.metadata:kMDItemKeyphraseVersion
/tmp/proj-data/fr_ign_README.txt:
com.apple.metadata:kMDItemTextContentLanguage
/tmp/proj-data/no_kv_README.txt:
com.apple.metadata:kMDItemKeyphraseConfidences
/tmp/proj-data/no_kv_README.txt: com.apple.metadata:kMDItemKeyphraseLabels
/tmp/proj-data/no_kv_README.txt: com.apple.metadata:kMDItemKeyphraseVersion
/tmp/proj-data/no_kv_README.txt:
com.apple.metadata:kMDItemTextContentLanguage
Removing them:
% xattr -c /tmp/proj-data/*_README.txt
% xattr /tmp/proj-data/*_README.txt
%
The *_README.txt files in the git repo don't seem to have these attributes.
Kind Regards,
Bas
