147492 – [PATCH] textproc/scim-bridge segfaults.

no flags

When trying to use scim-bridge with Emacs via scim-bridge.el[1], I got the following error:

SCIM: file-error: ("make client process failed" "no such file or directory" :name "scim-bridge" :service "/tmp/scim-bridge-0.3.0.socket-1001@localhost:0.0" :buffer " *scim-bridge(:0.0)*" :family local :server nil :noquery t)

On looking in the /tmp directory, I found following socket file created:

/tmp/scim-bridge-0.3.0.socket-1001@localhost:0.

And also it crashes sometimes due to this socket name mismatch
issue. The socket path created by scim-bridge is incomplete according
to other scim-bridge clients (e.g. scim-bridge.el).

After truss-ing, I figured out it is trying to create the socket with correct path name, but fails to create properly:

,---- an excerpt from: truss $(which scim-bridge)

The attached diff file fixes the issue. I don't use Qt4, but chances
are that textproc/scim-bridge-qt4 is buggy too, since they share same
distfile. Thus this diff also needs to be applied on
textproc/scim-bridge-qt4 .

I've filed a bug report[2] on their bug tracker.

How-To-Repeat: Make sure you're running in X11.

1. Install scim-bridge .

% sudo make -C /usr/ports/textproc/scim-bridge install

2. Execute scim-bridge.

% scim-bridge

3. Check the path name of the socket, iff scim-bridge is not crashed. 

% ls /tmp/scim-bridge*

You'll notice a path name ending with '0.' assuming your X11 DISPLAY is ":0.0".
