Package: xfstt
Version: 1.10-1
Severity: grave
Tags: upstream
During its start-up, xfstt creates the `/tmp/.font-unix/` directory in order to
place its socket there.
If, however, the above directory already exists, xfstt:
- doesn't create the unix socket there if the socket file doesn't exist,
- doesn't re-use the existing socket file, and
- fails to listen at a TCP socket even if configured so.
STR:
1. Make sure xfstt isn't running or stop it first.
2. As root, create the /tmp/.font-unix/ directory.
3. Delete /tmp/.font-unix/fs7101 (the socket file).
4. Start xfstt.
5. The daemon will start w/o any error:
> # service xfstt status
> [ ok ] xfstt is running.
>
> # ps -ef | grep xfstt | grep -v grep
> root 31878 1 0 02:00 ? 00:00:00 /usr/bin/xfstt --daemon
> --port 7101 --unstrap --encoding iso8859-1
6. In spite of the above, the socket file won't be re-created:
> # ls -l /tmp/.font-unix/
> total 0
7. Additionally, xfstt will no longer be listening at TCP port 7101:
> # lsof -p 31878

Normally, I'm also expecting 3 sockets in lsof output:
> xfstt 1663 root 0u unix 0xffff8838fffb7800 0t0 4774342
> /tmp/.font-unix/fs7101 type=STREAM
> xfstt 1663 root 1u IPv4 4774346 0t0 TCP *:7101
> (LISTEN)
> xfstt 1663 root 2u IPv6 4774347 0t0 TCP *:7101
> (LISTEN)
If I re-start xfstt, it'll remove and re-create the /tmp/.font-unix/ directory,
but this directory
shouldn't be managed by xfstt alone as it may be shared between multiple X font
servers (e. g.: xfs).
The problem stems from the following fragment in xfstt.cc:
> if (mkdir(sockdir, 01777) < 0) {
> error(_("cannot make socket directory %s!\n"),
> sockdir);
> close(sd);
> return -1;
> }
If the directory already exists and has the right permissions, xfstt should
just proceed.
If the directory already exists but lacks some permissions, xfstt should
attempt to change those (when running as root).
BTW, /etc/init.d/x11-common script from x11-common already does the job of
creating X11 socket directories,
so it could be enhanced to take care of /tmp/.font-unix, too.
