- Without this, recvMsg can be invoked before the event emitter gets a
chance to run. In this case, recvMsg.fd will be overwritten and the
original caller can end up emitting null.
- Adds new dgram module, for all data-gram type transports
- Supports both UDP client and servers
- Supports Unix Daemon sockets in DGRAM mode too (think syslog)
- Uses a shared Buffer and slices that as needed to be reasonably
performant.
- One supplied test program so far, test-dgram-pingpong
- Passes test cases on osx 10.6 and ubuntu 9.10u
This is needed in case the provided socket is not the default 'tcp4' type
(i.e. and needs different read/write/etc methods). With this patch, one can
call listenFD(sock, 'unix') to bind to existing UNIX domain sockets.
Now that FD passing is in master, it'd be great to be able to use a received
socket (which has already had bind(2) and listen(2) called on it) to fire up a
new net.Server instance. This patch adds a net.Server.listenFD() method which
will start up the accept watcher on the provided FD.
The fs.readFile bug was hiding another bug that was causing this test
to pass, even so it was broken:
require.async("../fixtures/throws_error1") in test-module-loading.js
This patch fixes the original test by running _compile within a
try..catch block for _loadScript.
_loadScriptSync also had some useless (deprecated?) code for dealing
with module entry point exceptions. This code was also removed for
greater clarity.
fs.readFile was executing a callback in a try..catch context, which is
a problem in itself. To make matters worse, it would re-execute the
same callback if there was an execution.
This patch fixes both of these problems.
a) create a layer of indirection in net.Stream to allow swapping in
different read/write implementations and
b) emit an 'fd' event when file descriptors are received over a UNIX pipe,
as finally as a tangential benefit
c) remove a bunch of conditionals from the primary codepaths for
ease-of-reading.
Notes:
- Currently only accepts numeric user and group ids.
- No tests, as tests depend on getpwuid and getgrgid.
- No documentation, as there is no tests and this is experimental.
