Subject: Create socket link for debug mode
X-Git-Tag: accepted/tizen/common/20170203.161757~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F68%2F112668%2F5;p=platform%2Fcore%2Fappfw%2Faul-1.git

Create socket link for debug mode

When the application is launched by the debugger,
the socket link should be created for re-launching the application.
Until now, the running application by the debugger could not
get the re-launch request.

Requires:
 - https://review.tizen.org/gerrit/#/c/112729/
