Hi, first, sorry if this is an inappropriate place to ask.
I am spawning a detached child process and am able to communicate via IPC
just fine, I can shut down the master process and leave the child running.
What I need to do is restart the master and reconnect to the same IPC
channel.
I am creating the process like so:
var child = spawn('node',
['--harmony', '--use_strict', './src/screamer.js'],
{ detached: true, stdio: [process.stdin, process.stdout,
process.stderr, 'ipc'] });
Everything I've read, from the source to docs, seems that the fds for the
child process are created in relation to the order of the stdio options
array, eg, the ipc chanel should be fd 3 (stdio being 0,1,2)
When I attempt to open fd#3 on the child process, it doesn't appear that
this is the case as it seems the fd doesn't exist. (actually the fd shows
up in ls - perhaps it does exist and not accessible this way?) I tried
opening it for writing+read and got a ENOENT..
cat /proc/15745/fd/3
cat: /proc/15745/fd/3: No such device or address
I don't mind writing my own code to mimic child.send and such to make it
work but first I need to be able to reopen the fd socket and pass/read json
to/from it.
Do I just need to listen on a socket wired to that fd or something?
Help would be very much appreciated!!
