After I upgraded my Jira instance from v4.4.3 to v5.0.7 I found that the permissions on the $JIRA_HOME directory had changed to something I'd never seen before:
[13:20:40 lhawkes@]$ ls -lA /var/atlassian/jira_v422/data/ total 0 ?--------- ? ? ? ? ? avatars ?--------- ? ? ? ? ? attachments
The $JIRA_HOME directory is owned by user jiraapp. If I try the same command as user jiraapp I get a different result:
[13:27:14 lhawkes]$ sudo -u jiraapp ls -lA /var/atlassian/jira_v422/data/ total 8 drwx------ 21 jiraapp jiraapp 4096 Aug 21 16:29 attachments drwx------ 2 jiraapp jiraapp 4096 Jun 12 17:51 avatars
In the specific case, the parent folder (/var/atlassian/jira_v422/data/) gives read permissions to all users
[13:31:49 lhawkes@usindjira01t:jira_v422]$ ls -lA /var/atlassian/jira_v422/ total 76K drwxr--r-- 4 jiraapp jiraapp 4.0K Aug 29 19:35 caches/ drwxr--r-- 4 jiraapp jiraapp 4.0K Nov 14 2011 data/
Jira is hosted on a Red Hat Linux system. I'm familiar with unix permissions and the standard behavior when one doesn't have permissions for a specific directory. I've never seen this before. So far I haven't seen any problems that I can tie directly to this behavior, but it is odd.
Note: I realize that the directory is called jira_v422 and I'm talking about an upgrade from 4.4.3 to 5.0.7. The name is a relic from my original installation of Jira v4.2.2.
Oooh, pretty. The ?------- usually means "I, the operating system, either can't read the permissions, or I can, but I'm not going to tell you for some reason".
Last time I saw that, it was because I'd created the file system on another computer, with VMS, and later pulled the drive and whacked it in a Linux box. I was able to reset it with a simple "chmod" as root, and as soon as I had, all the files worked fine again (And still are). I don't know how you'd do it without swapping OSs though!
I suspect that could be a bit like my "did stuff to the disk with another operating system", but I'm not going to pretend I'm any form of Unix expert and claim that's the explanation!
Anyway, if you've changed permissions, could you check what you see with three different users? The owner you want to use, root, and some other user that isn't anything to do with Jira. I'm afraid I'm completely stuck (I use Linux a heck of a lot, but this is quite deep into "obscure stuff most people won't run into" territory), but I suspect someone here with more Unix experience would ask that question.
Addendum: I have tried changing the permissions of the affected files and I see the same behavior. The files' permissions change, but even if they are 777 (rwxrwxrwx), the files are still shown as having permissions
?--------- ? ? ? ?
This is the bit that's the most confusing to me, no pun intended.
