It ends up spawning test/fixtures/recvfd.js -// as a child to test desired behavior. What happens is -// -// 1. Create an in-memory pipe via pipe(2). These two file descriptors -// are not visible to any other process, and so make a good test-case -// for sharing. -// 2. Create a a UNIX socket at SOCK_PATH. When a client connects to this -// path, they are sent the write end of the pipe from above. -// 3. The client is sent n JSON representations of the DATA variable, each -// with a different ordinal. We send these delimited by '\n' strings -// so that the receiving end can avoid any coalescing that happens -// due to the stream nature of the socket (e.g. '{}{}' is not a valid -// JSON string). -// 4. The child process receives file descriptors and JSON blobs and, -// whenever it has at least one of each, writes a modified JSON blob -// to the FD. The blob is modified to include the child's process ID. -// 5. Once the child process has sent n responses, it closes the write end -// of the pipe, which signals to the parent that there is no more data -// coming. -// 6. The parent listens to the read end of the pipe, accumulating JSON -// blobs (again, delimited by '\n') and verifying that a) the 'pid' -// attribute belongs to the child and b) the 'ord' field has not been -// seen in a response yet. This is intended to ensure that all blobs -// sent out have been relayed back to us. - -const common = require('../common'); -const assert = require('assert'); - -const child_process = require('child_process'); -const fs = require('fs'); -const net = require('net'); -var netBinding = process.binding('net'); -const path = require('path'); - -var DATA = { - 'ppid' : process.pid, - 'ord' : 0 -}; - -var SOCK_PATH = path.join(__dirname, - '..', - path.basename(__filename, '.js') + '.sock'); - -var logChild = function(d) { - if (typeof d == 'object') { - d = d.toString(); - } - - d.split('\n').forEach(function(l) { - if (l.length > 0) { - console.error('CHILD: ' + l); - } - }); -}; - -// Create a pipe -// -// We establish a listener on the read end of the pipe so that we can -// validate any data sent back by the child.
