Why memcpy does not work? It was working recently. What version of node do
you use?

Hi,
I need to convert a Buffer to an ArrayBuffer and vice versa. Is it
possible to do so that without copying mem?
npm memcpy
BTW I have discovered that named pipes are working in Node under Windows
and give bigger transfer rates than tcp. Thought haven't tried it with
cluster.

And this is pretty low number - about 8 Mbit for me.

What is strange - that using Uint8Array to copy data from Buffer to
ArrayBuffer in a loop is much slower.

Yes I understand what is happening.

Is there something I have to do to use this in windows?

New group rules:
1. Your async code is incorect as you close file before all write operation
complete.
2. WriteStream buffers written data until other end is ready to consume
data. So you actually first fill memory with data and then write it to
file.

Hello,
I need to distribute about 100Mbit data stream among several applications
locally.
So I have decided to use UDP multicats on loopback interface.
In general this works except the data loss.
So I have created simple sending and receiving app.
Yes It was me who started the process:

Not really, it looks like it was
the code:
var buf = new Buffer(1024*1024);
setInterval(function(){
var ab = buf.toArrayBuffer();
var b = new Uint8Array(ab);
},10);
quickly eats memory and crashes node.
Invoking it every 20 or 100 ms just prolongates agony.

It looks like your problem is on client side.

I thought I could get away without streaming at first. Some browsers only
like streaming, so
I think you should create file
exportfb.js:
window.fb = require('node-firebird');
and then
browserify exportfb.js browser-index.js
then try exmaple w/o line
var fb = require(node-firebird);

Hi Paul,
You will not be able to use neither node-firebird-libfbclient nor
node-firebird directly from browser as these modules are designed to work
in nodejs, not in browser.

I have finally found what is wrong. Readable.push() may call _read again
synchrnously so whole thing becomes recursive and buffers are swapped as I
am adjusting position after call to push.

It looks like reading from growing file

How can I detect what part of file it is safe to read?

Yes return is missing before setTimeout. I have updated gist. But that
does not change result.

Looks like it is not solved.
Sometimes I get situation when fs.ReadStrem neither emit 'readable' nor
'end' when used on growing file in non flow mode. And I have no event to
resume reading. Except maybe some timeout.

Or maybe I understand it wrong.
When I call fs.ReadStream.read should I expect it will emit 'end' during
call?
Ok it is better to look in sources.

This is not funny now. I am not able to make such simple thing.
Now I am getting swapped chunks of data.
https://gist.github.com/xdenser/8887437
when new read stream starts first 2 chunks of data are swapped.
How is it possible?
