The files `unused`, `badunused` and `tmpunused` in `.git/annex/` do not have the correct permissions when the git repository is set to `--shared=group`. Such files are `600`, while they should be `660`, as other files in `.git/annex`.
For this reason, when those files are created, they are accessibile only to one user (the owner), triggering errors when other users in the group attempt things like `git annex unused` or `git annex dropunused`. At least this occurs with git-annex 6.20171018+gitgbb20b1ed3-1~ndall+1 .
To reproduce the problem:
git init --shared=group
git annex init
echo test > test
git annex add test
git commit -m test
git rm test
git commit -m removed
git annex unused
you get:
unused . (checking for unused data...) (checking master...)
Some annexed data is no longer used by any files:
NUMBER KEY
1 SHA256E-s5--f2ca1bb6c7e907d06dafe4687e579fce76b37e4e93b7605022da52e6ccc26fd2
(To see where data was previously used, try: git log --stat -S'KEY')
To remove unwanted data: git-annex dropunused NUMBER
ok
Conversely, from another user of the group you get:
> git annex unused
unused . (checking for unused data...) (checking master...)
Some annexed data is no longer used by any files:
NUMBER KEY
1 SHA256E-s5--f2ca1bb6c7e907d06dafe4687e579fce76b37e4e93b7605022da52e6ccc26fd2
(To see where data was previously used, try: git log --stat -S'KEY')
To remove unwanted data: git-annex dropunused NUMBER
git-annex: .git/annex/unused: openFile: permission denied (Permission denied)
failed
git-annex: unused: 1 failed
Moreover:
> git annex dropunused 1
git-annex: .git/annex/misctmp/mergedrefs.0: createDirectory: permission denied (Permission denied)
This is somewhat expected, because the permissions of `unused`, `badunused` and `tmpunused` are `600`:
> ll .git/annex/
total 40
drwxrwsr-x 5 ele testgroup 4096 dic 19 14:50 ./
drwxrwsr-x 9 ele testgroup 4096 dic 19 14:50 ../
-rw------- 1 ele testgroup 0 dic 19 14:50 badunused
-rw-rw-r-- 1 ele testgroup 345 dic 19 14:49 index
-rw-rw-r-- 1 ele testgroup 41 dic 19 14:49 index.lck
drwxrwsr-x 2 ele testgroup 4096 dic 19 14:49 journal/
-rw-rw---- 1 ele testgroup 0 dic 19 14:49 journal.lck
-rw-rw-r-- 1 ele testgroup 62 dic 19 14:49 mergedrefs
drwxrwsr-x 2 ele testgroup 4096 dic 19 14:49 misctmp/
drwxrwsr-x 3 ele testgroup 4096 dic 19 14:49 objects/
-rw-rw---- 1 ele testgroup 0 dic 19 14:49 precommit.lck
-rw-rw-r-- 1 ele testgroup 0 dic 19 14:49 sentinal
-rw-rw-r-- 1 ele testgroup 21 dic 19 14:49 sentinal.cache
-rw------- 1 ele testgroup 0 dic 19 14:50 tmpunused
-rw------- 1 ele testgroup 101 dic 19 14:50 unused
If this is the intended behavior, could you please explain me how to use `git annex unused` and `dropunused` in a shared repository?
