Subject: global_send_sigint
Date: Wed, 24 Feb 2010 19:47:46 -0800 [thread overview]
Message-ID: <20100225034746.GA18829@us.ibm.com> (raw)
global_send_sigint is -1 by default.
If it is -1, we either send SIGKILL or SIGINIT depending on whether
we started "new pidns with init" or "new pidns without init".
If global_send_sigint is explicitly set to 0 by user (--signal is set).
no signal is sent.
Given that we are making restart() available in libcheckpoint.a, would
it make sense to switch the behaviors of 0 and -1 ?
i.e if global_send_sigint is 0, send the default signal (SIGINT or SIGKILL).
If it is -1, then don't send any signal.
That way, applications of restart() (i.e LXC) can simply
memset(&args, 0, sizeof(args))
and get the default behavior. Now they have to explicitly set to -1.
