When -reincarnate-reexec is given we run execv to restart FS. If
argv[0] isn't a full pathname then execv is going to fail. While not
common for a FS system started by init, this is a common occurrence
when FS is started from the shell.
Now if execv fails, we'll try execvp. If that fails too then we'll
fall back on the normal reincarnation behavior.
Previously what would happen in that case is god would descend from
the heavens and become mortal. Leaving heaven absent, all hope for
reincarnation was lost.
(That is, we'd simply return from reincarnate_protect and the
supervisor process would become the new instance of FS, so the trick
would only work once.)
If you start freeswitch with -reincarnate or -reincarnate-reexec, FS
will restart automatically in the event of an unexpected exit.
Currently, you can cause FS to immediately call exit(0) with `fsctl
shutdown now`, or you can have it call abort() with `fsctl crash`.
Which are both nice, but if you have reincarnation engaged, you really
might want FS to call exit([non-zero]) so the great supervisor
immediately breathes life back into your system.
This is now available via `fsctl shutdown reincarnate now`.
For numbers with variable length, there should be a timeout to wait for
further digits before routing the number. This has been prepared with
the skinny-wait target, which waited forever. This patch implements the
digit timeout which routes the call after the timeout has elapsed. The
timeout can be configured in the mod_skinny XML settings
("digit-timeout") and defaults to 2 seconds.
This implementation has been requested and sponsored by Blackned GmbH.
