Re: [nodejs] Re: Is it a good idea for me to learn node.js?
Rails is a framework on top of Ruby. So you can't compare Rails to Node.JS. You can do CRUD with Node.JS. You can do in Nodejs everything that can be done in Ruby. Only the default paradigm is different. One is synchronous, blocking and the other is asynchronous, non-blocking by default. You can use libraries like EventMachine for nonblocking I/O in Ruby, but that also means you need to write your own libraries for HTTP, TCP, File I/O, Database wrappers etc (There are many available now like em-http-request, em-websocket etc). The reason to use NodeJS is the fact that its Javascript and all the modules written for Node are inherently asynchronous, non-blocking. If you want Rails in Node.JS you have Geddyhttp://geddyjs.org/features.html. Geddy http://geddyjs.org/features.html is an MVC framework.

Re: [nodejs] [Ann] UglifyJS 2.0
Yeah I understand the purpose of maintaining comments; I've actually written a lot of source-to-source transformations myself. The reason I ask is that I always found it cumbersome to stick non-AST information on the AST itself. For instance, for /* this is my loop */ (/* this is my initializer */ var ii = 0 /* there it is! */;;). I tortured myself for a long time messing with maintaining comments and whitespace when I found that the solution is actually implicit in the token start/end positions. If you're rendering the AST to string and you've got the source tokens attached to each node, you can just look at the original source string to find the comments and whitespace. Like I said, you should check out the fibers transformation in Streamline. It does a source-to-source transformation while maintaining *all* non-semantic source data (whitespace comments). The other solution I've seen is to maintain a lastDocBlock variable in your tokenizer state. Then when the parser parses a function, you just attach `lastDocBlock` to the node that way. That's a pretty simple and easy to implement solution and it handles concerns about maintaining copyright information, but it won't maintain whitespace or esoteric comments which is desirable in many situations. On Wed, Aug 29, 2012 at 8:07 PM, Scott Taylor sc...@railsnewbie.com wrote: Obviously it depends what you are trying to do.

[nodejs] HTTP Server Throttling
I've been working on a web server framework of my own using a cluster of workers sharing a single listener. The documentation for clusters just says that workers workers sharing a listener will just automagically throttle themselves, but I find that unacceptable. I want to be able to tell a listener in one of the workers to not accept new connections until I unblock it. I have found only one way of doing this and it's much less than satisfactory. You can call the close method on the server which will stop the server from accepting new connections, but the only way to restart it is to create a new server! This works, but a) it's creating a new server instance when all I really want to do is allow new connections to be accepted again, and b) I'm not sure how the backlog works in a node HTTP server. Is there a way to tell how large the backlog is? is there some way to just configure the maximum number of concurrent connections per listener? Is the backlog shared across all of the shared listeners in all of the workers? Is there documentation somewhere on the underlying implementation? -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups nodejs group.

[nodejs] Re: Async: When it is usefull?
In JavaScript you most of the time don't really have a choice whether to make something async or sync. When there are only synchronous operations in a function there is no purpose in using callbacks. However when you use async operations like I/O you have to use callbacks. The things is that callbacks are only relevant for functions that give the main thread free to other operations and wait for something external to happen.

Re: [nodejs] problem with socket.io
My guess is that you are directly opening your HTML file from the file
system in a browser instead of via a localhost URL. I think you need an
HTTP server that works with Socket.IO and serves your static HTML file. You
can use Express or Strata for that. I can send you an example of setting
that up if you need it.

[nodejs] How cluster master pass data to workers ondata listener
Hi guys, I need your help
As how node cluster module works, the workers works like normal Socket
Server, also it can listen to a public port, and handle the data client
pass it.
I have couple question about cluster.
1. listening
The master process listen at the public port, but what those workers with
the code `listen(port)` does? did the worker listen at somewhere, or it
just a fake listen?
2. receive data
If I am not misunderstanding, the data from client is send to the master
process, and the master process send an internalMessage like
worker.send(data), if so, the worker should handle data at
process.on('message',..) but not socket.on('data', ...), so we have to
change our workers code not like what cluster module did.
I notice there is a method called cluster._getServer, which would give the
worker a `handle` object which set to `socket._handle`.
3. send data back to client
When send to client, the worker process should send data to master process,
we need call `process.send` to the master process, and the master send data
back to client.
I know few thing about multi-process binding on a same port.

Re: [nodejs] Re: Restricted static files
A quick and dirty way is to wrap express.static middleware. You can try
something like:
app.use(function(req, res, next){
// do authentication
if(authorized){
express.static(/private)(req, res, next);
} else {
next();
}

Re: [nodejs] How to use soap client over HTTPS with a self-signed certificate?
Don't forget to specify an agent of explicitly set agent = false. If you
don't the global agent will be used and your certificate will be ignored.
There's a note about that behavior in
http://nodejs.org/api/https.html#https_https_request_options_callback but I
recently overlooked that and it took me a while to figure out what was
going wrong.

Re: [nodejs] [Ann] UglifyJS 2.0
Well, the good news is that I'm maintaining both start/end tokens in all AST nodes, and inside tokens I maintain line/col/pos/endpos too. And on top of this, there's a comments_before array in all tokens which tell what comments were found before that token (though that's not so useful for perfect reconstitution of whitespace). Cheers, -M. On Thu, Aug 30, 2012 at 10:03 AM, Marcel Laverdet mar...@laverdet.com wrote: Yeah I understand the purpose of maintaining comments; I've actually written a lot of source-to-source transformations myself. The reason I ask is that I always found it cumbersome to stick non-AST information on the AST itself. For instance, for /* this is my loop */ (/* this is my initializer */ var ii = 0 /* there it is! */;;). I tortured myself for a long time messing with maintaining comments and whitespace when I found that the solution is actually implicit in the token start/end positions. If you're rendering the AST to string and you've got the source tokens attached to each node, you can just look at the original source string to find the comments and whitespace. Like I said, you should check out the fibers transformation in Streamline. It does a source-to-source transformation while maintaining *all* non-semantic source data (whitespace comments). The other solution I've seen is to maintain a lastDocBlock variable in your tokenizer state. Then when the parser parses a function, you just attach `lastDocBlock` to the node that way. That's a pretty simple and easy to implement solution and it handles concerns about maintaining copyright information, but it won't maintain whitespace or esoteric comments which is desirable in many situations.

Re: [nodejs] How cluster master pass data to workers ondata listener
nice to meet you too.
all workers listen to the same address, why no problem like address
already bind.
why i care about how it works because the i need dispatch connection to
workers manually, and the connections need communication, you know like a

Hi guys, I need your help
As how node cluster module works, the workers works like normal Socket
Server, also it can listen to a public port, and handle the data client
pass it.
I have couple question about cluster.
1. listening
The master process listen at the public port, but what those workers with
the code `listen(port)` does? did the worker listen at somewhere, or it
just a fake listen?
2. receive data
If I am not misunderstanding, the data from client is send to the master
process, and the master process send an internalMessage like
worker.send(data), if so, the worker should handle data at
process.on('message',..) but not socket.on('data', ...), so we have to
change our workers code not like what cluster module did.
I notice there is a method called cluster._getServer, which would give
the worker a `handle` object which set to `socket._handle`.
3. send data back to client
When send to client, the worker process should send data to master
process, we need call `process.send` to the master process, and the master
send data back to client.
I know few thing about multi-process binding on a same port.

[nodejs] How is the cache supposed to work
Hi all I am doing an investigation which relates to the npm cache. I though I understood how the cache worked, but Iam seeing behavior in recent builds that is different than what I expected. It may be however that I am misunderstanding how the cache is used. I have not walked the code yet (which I can do if necessary) but I assumed there's enough folks here that are familiar. My current understanding / expectation 1. If a module is retrieved from the npm registry it will be stored in the cache. 2. If I manually call 'npm cache add on a module it will add it to the cache such that when retrieved the cached version is used. 3. If I retrieve that module either directly via npm install or via being specified in an app/module package.json then it will be retrieved from the cache. This includes native modules - My assumption here is that if I specify a version explicitly that does not match what is in the cache it will be downloaded - If I don't specify a version it will use whatever is in the cache. - If I specify a range and the version in the cache matches the range then it will be used. I appreciate any clarification you can give.
