| 26 | * |
|---|
| 27 | * 1. Put all the arguments to pass in to a string list. |
|---|
| 28 | * |
|---|
| 29 | * 2. Connect to the proxy (this will be our primary control |
|---|
| 30 | * socket). |
|---|
| 31 | * |
|---|
| 32 | * 3. Read this string list and write the following to the socket: |
|---|
| 33 | * (a) The PROC_INFO command. |
|---|
| 34 | * (b) Integer sized data with the number of arguments to |
|---|
| 35 | * follow. |
|---|
| 36 | * (c) For each argument to pass, first send an integer which |
|---|
| 37 | * tells the proxy how many bytes are coming in that |
|---|
| 38 | * argument. |
|---|
| 39 | * |
|---|
| 40 | * 4. Open two new sockets and connect them to the proxy. |
|---|
| 41 | * |
|---|
| 42 | * 5. On the first new socket, send USE_AS_STDOUT and the second |
|---|
| 43 | * send USE_AS_STDERR. |
|---|
| 44 | * |
|---|
| 45 | * 6. For the first process, open a separate socket and send the |
|---|
| 46 | * USE_AS_STDIN command on it. |
|---|
| 47 | * |
|---|
| 48 | * 7. We need to figure out what to do with the LAUNCH_JOB |
|---|
| 49 | * command; since it's going on a different socket, it might go |
|---|
| 50 | * out-of-order. Maybe a state machine on the proxy to see if |
|---|
| 51 | * it got all the information it needs to launch the job would |
|---|
| 52 | * work. |
