Description Daniel Augustin 2014-06-10 10:48:16 UTC
The currently stable timezone-data-2014a installs a symlink

/usr/share/zoneinfo/posix -> .

which causes some programs to hang, because they loop endlessly through the zoneinfo directories.

I have found this symlink on all my gentoo boxes, some really old with a lot of updates, some rather new.

I have not found this symlink on any other distribution, I checked archlinux, Ubuntu and Fedora.

On Fedora this is a actual directory.

Of course the programs are at fault here too for their endless loops, but as no other distribution is using this symlink, I assume it could be removed.

Program not working here:

When removing the symlink "SecureCRT" works fine and I didn't encounter any issue with other programs yet.

Reproducible: Always

What programs?
Comment 2 Daniel Augustin 2014-06-10 13:37:51 UTC
Like mentioned above I found this in SecureCRT:

If needed, I can reproduce an strace showing the endloss loop of "posix" directories in the syscalls.
Comment 3 Jeroen Roovers (RETIRED) gentoo-dev 2014-06-10 20:21:54 UTC
"SecureCRT" is not under our control. It is not a Gentoo project or even a package in the tree.
Comment 4 Ian Stakenvicius (RETIRED) gentoo-dev 2015-04-07 16:15:45 UTC
postgresql also suffers from such an issue.  IIRC there is a bug about it (and I believe upstream doesn't see it as a valid bug, too), but this bug still has not been resolved at this time, ie, a new postgresql[server] install with default 'emerge --config' will still fail to launch:

# /etc/init.d/postgresql-9.1 start
 * /run/postgresql: correcting mode
 * Starting PostgreSQL ...
 * start-stop-daemon: did not create a valid pid in `/var/lib/postgresql/9.1/data/'
 * Check the log for a possible explanation of the above error. The log may be
 *     /var/lib/postgresql/9.1/data/postmaster.log
 * Or wherever you configured PostgreSQL 9.1 log messages to be sent.                                                     [ !! ]
 * ERROR: postgresql-9.1 failed to start

# tail /var/lib/postgresql/9.1/data/postmaster.log
FATAL:  exceeded maxAllocatedDescs (16) while trying to open directory "/usr/share/zoneinfo"

If 'posix' was a directory containing simlinks to all of the other files in /usr/share/zoneinfo (except itself) , instead of a symlink-to-. , we wouldn't get any such infinite loops.  Maybe not the most ideal setup but it would work.
