I'm sorry to keep picking on this but i want to undertand, why would MappedPassword have a default value that i can't override and that is shown to user with ProtoUser if i don't override the full signup form's xhtml? I would like to think that i can start any project, extend proto user and have a register/login system that is very easy to undertand for all user and i know that having a pre-filled value seems to be a non- important issue, still is one of the most voted things in my uservoice!

[Lift] Rendering a template bit
I want to do the following pattern, i don't know how(or if its possible) to do it in lift: - I want any part of my code to call a Site.render() where site is a model and render is a function inside that model that will print it the information - I want the xhtml to be in a html file so that any designer/html guy can play with it and its css/html. (also they won't have to compile and/or scala:cc after every change). Is this possible? I was playing with the lift:embed what=/commons/site / and sending parameters, but i didn't know how to catch those params in the xml, has anyone done this pattern?

If you do not like the way a particular feature is implemented in Lift, you can copy the source code and change the implementation (Lift's Apache 2 license allows for that). Lift is layered. You can change out pieces that don't suit your needs. You don't like the issues related to MegaProtoUser (like the whole templates in code thing), then copy the code into your user class and change the template calls to load the templates however you want. If you don't like how MappedPassword is implemented, then do your own implementation.

The thing is that i want the NodeSeq to reside in a html file, not
inside the model.

What you want can be done with very basic usage of snippets (the way
that templates interface with code in Lift). In your template:
lift:YourSnippet.foo/
Then in YourSnippet.scala:
class YourSnippet {
def foo(xhtml: NodeSeq) = Site.render()

Make sure render returns a NodeSeq.

[Lift] Re: Question about megaprotouser S.error
well that seems great! I use the snapshot so if you finish that and want to make someone very happy, you can send me an example of how it ended up working and i will be very very thankful! The last piece of the puzzle is the ** default value of the mappedPassword, since its part of the mappedPassword and not of the ProtoUser. And its a val, i don't know how to override it. What is the reason of this default value?

You can override these, but not on a single key base, you have to replace all. But obviously this is a bug! The core lift properties should contain an entry. But they do not. Well, they do, but the key is password.must.be.set which is a ways better key IMHO. So the bug is in the Scala code of ProtoUser.

testSignup, but did not see any obvious cause for this trouble in:
def testSignup() {
theUser.validate match {

[Lift] API data linked to a user
I'm doing a prototype (learning a little bit more of everything) just for fun using lift and a Firefox extension to understand the usual infrastructure of a delicious api kinda thing. Right now i have the communication from the FFext to a restApi in scala (and it was painless to do it =) ), but right now im sending the username and password in each request so the api can decide if the information should be stored and if so, linked to what user. Analyzing a little bit of code of other firefox extensions and some network behaviour i realize most of them are not sending that auth information in every request, but the server already have a way to associate a session with the FFext(im not sure). So the options i have so far are: -keep sending the username and password(not a good idea) -keep sending the username and password encripted(any ideas what algorithm to use here?) -Generate a token after the login and after that handshake trust that token(any guideline on the use of this tokens? possible security issues?) -Use a OAuth server/cliente industry standard bullet-proof handshack Also, i would like to know how important is to encrypt the bjax (browser ajax) post information? Im sending information i would like to know its secure. I just wanted to bring this ideas to the table to know a little bit more of the best practices and security involved in this kind of projects and if someone has a very simple solution to trusting a input received like this and/or how to link this to a user, help me brainstorm pls =) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Comet Actors - single browser, multiple tabs, same URL - out of control GET problem
That seems like a logical reason why this is like this, but if i open 2 tabs of http://demo.liftweb.net/, both tabs start to send ajax request every 100ms, that is 20 ajax request per second, 72k per hour, so if an app had 100 crazy users who happen to open 2 tabs of the app (this happens to me a lot, im messy with my tabs) that means 7.2 million request per hour to the server? isnt that something we might want to avoid somehow? I'm guessing we can't really fight the connection limit, but we should be able to specify a frequency to the js if we are going to enter to a polling policy (instead of long poll)?

When we go to the same URL in two tabs in the same browser, we see that the long polls (GET requests) return immediately in rapid fire succession and this behavior continues until we exit one of the tabs. We thought maybe we did something wrong in our code, so we tried the same thing using demo.liftweb.net. We saw the same behavior in the demo site that we see in our site. If you try this with something else like Gmail, it does not show this behavior. It's not a bug. There is a 2 connection per server per browser limit (in most browsers although Chrome and FF 3.5 apparently have relaxed this limit). If there is a long polling operation in progress and a second request comes into the same session, Lift will immediately end the long polling operation in order not to starve the connections.

[Lift] Crazy idea for lift's mega proto user: admin panel.
I was thinking about how wonderful it is to get a login/register/ forgotPassword functionality with mega proto user and how it could become even better with a good tool for creating an admin section. I'm just adding the idea here so maybe if other people find value it could be considered for development(or probably it already is, i don't know). Adding an admin panel to mega proto user where the moderators/admins could change some options(like the way a user is validated, if gzip is enabled, etc) would be great for the end users of our apps, since it would be easier to change and maintain the site. Being a administrator at a Invision Power Board forum and having a couple of wordpress blogs, i see a lot of potential on this as a admin/ dev tool! Listing some of the things that i can imagine in this panel are: -phpMyAdmin-type of DB admin(browse your data easily, remove/change/ add stuff to it without having to create a CRUD for each thing) -execute queries -List the actor(and comet actors) with possibility to kill/reset them -Memory use analysis. -Statistics of use(hits, referrals, etc) -Options (any object/class/trait could have a val foo = adminPanel.option(category,optionName,description,defaultValue, otherValues[]) and be included in this place, of course the categories could create different menus. -User management(ban, authorize, give admin-rights). -Simple to-do list that all admins can edit -Log of errors/warnings/exceptions -Css editor -Easy-logo changer -File Manager(upload your images and stuff here) -String editor (you can change any default string from the megaprotouser forms and the index?) Also, a very polemic(and i think bad idea, but its common to see this in admin panels): -Installable plug-ins for this panel I know this seems like one step away from being a full blown CMS, forum, blog, etc. But if its extensible while we are building an app, it will be very useful for the different moments of development and use. Of course i don't expect any of this to be done right now, i understand there are a couple of integrations and bigger things going on but i really wanted to brainstorm on this with you guys! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Post form and return file?
I'm guessing that the easier one would be the way to go. If the user clicks on agree to these terms and get a new screen with a link, that link must only be accessible after agreeing in the last screen. If it could be the other way(click and get the file), it seems like there would be no perma link to the file, and that would accomplish the there's no other way to get this file but to agree to the terms Right now I'm playing with the StreamingResponse but can't figure out how that code is called, do i create a menu item that will be accessible from a view and in the view i have that code? or what is the usual pattern for using that code?

In the above example we are returning a head node as well which will
be merged by Lift automatically in the real page head. Then I'm
using Lift's JavaScript abstractions to call on load function
myStartupFunction. Instead of
head{Script(OnLoad(Call(myStartupFunction)))}/head you can also
use

[Lift] Re: Getting Started tutorial - not understanding some syntax
Viktor, that was a great explanation, im sure ben will apraciate that
kind of teaching =)
A follow up question that just made me wonder, what is the diference
between
val square = (x : Int) = x * x
and
def square(x:Int):Int = x * x
?
On Jul 30, 1:49 pm, Viktor Klang viktor.kl...@gmail.com wrote:
Hello Ben!
the following:
val square = (x:Int) = x * x
val square is the equivalent of a final reference in Java.
(x : Int) = x * x
This constructs a Function instance that takes an Int and returns that Int
squared.
The equivalent Java code would be something like:
interface FunctionR,P //We're ignoring variance here, as to not confuse
{
public R call(P p);
}
final FunctionInteger,Integer square = new FunctionInteger,Integer() {
public Integer call(Integer i)
{
return i * i;
}
}
And then you can do:
square.call(2) // 4
So, back to Scala:
val square = (x : Int) = x * x
square(2) // 4

Hi,
I feel I must apologise for this post ... I've only been doing scala
for a week, and lift for 3 days, but I'm stuck.
I'm coming from an experienced java background, just struggling with
some scala constructs.
I feel I understand the basics of lambda and function literals - but
I'm blown away by some of the syntax in the lift Getting Started
tutorial.
For example, given :
val mylist = Array(1,2,3)
mylist..foreach(v = println(v)
Here I understand where v comes from - its each int in the list.
In the tutorial (http://liftweb.net/docs/getting_started/
mod_master.htmlhttp://liftweb.net/docs/getting_started/%0Amod_master.html
)
there is a function desc (Listing 15) :
private def desc(td: ToDo, reDraw: () = JsCmd) =
swappable(span{td.desc}/span,
span{ajaxText(td.desc,
v = {td.desc(v).save; reDraw()})}
/span)
For my own brain to try and break it down, I have :
private def desc(td: ToDo, reDraw: () = JsCmd) = {
val myFunctionLiteral = (xxx: String) = {td.desc(xxx).save;
println(!Desc function : + xxx); reDraw()}
swappable(span{td.desc}/span,
span{ajaxText(td.desc, myFunctionLiteral)}/span)
}
This is called from the doList method :
private def doList(reDraw: () = JsCmd)(html: NodeSeq): NodeSeq =
toShow.
flatMap(td =
bind(todo, html,
desc - desc(td, reDraw)
))
I understand where the ToDo object td is coming from, and how the
reDraw thing works, and how they are passed to the desc function,
but what I don't understand at all is where the val xxx in
myFunctionLiteral comes from ?
How is it passed into the function ? Is it currying ?
I'm sorry for such a vague question, I'm totally at sea here.
Thankyou for reading this, and for any help you may provide !
Ben

The problem of loading big Xml files in Scala is already a challenge but for now i assume i have unlimited memory. The problem i have how to test it. Test it? like automated testing or test it want to know it works. If its the second, how about making a simple html file with a file submit form, add a sitemap entry to a lift application and create a snippet that parses that file and print the time it takes to crunch it! =) If you have no idea how to do this I would recomend buying the Lift book ( http://www.apress.com/book/view/9781430224211 which is not quite easy or polished but its a great way to go head first into the liftworld) Using scala interpreter mode i could test the Xml loading and parsing, now i need to load it into database and i have Mapper setup for my schema. Calling this job from simple Web snippet is my only choice?

I hope if there is, someone will point you in the right direction, all I can do is point you to that parser: http://technically.us/git?p=dispatch.git;a=blob;f=src/main/scala/dispatch/Json.scala;h=776da7b6c399d2985dfbed74bd31a197568360f9;hb=HEAD On Jul 9, 10:35 am, Jeppe Nejsum Madsen je...@ingolfs.dk wrote: Hi, Has anyone made a typesafe JSON builder?

[Lift] Speeding load time; liftAjax.js and other javascript minified?
I dont know how liftAjax.js is generated, or if it changes or not, also I have no idea (if it regenerated) how it could be minified, and I know that minification seem like a micro-optimization but... With just GZipping and Javascript minification working together, the load time dropped from 16 seconds to just under 10 seconds. I was absolutely extactic at the progress I was making so for and so was my client! http://www.site-reference.com/articles/Website-Development/YSlow-Helping-slow-web-pages-load-faster.html For Google an increase in page load time from 0.4 second to 0.9 seconds decreased traffic and ad revenues by 20%. For Amazon every 100 ms increase in load times decreased sales with 1%. http://www.svennerberg.com/2008/12/page-load-times-vs-conversion-rates/ So, analyzing a couple of lift apps with YSlow I find a couple of things that could be done to improve the average load time. Of course there's a lot of impact on how you do your css, where you host css and images(and how), compresion, server configuration, javascript and css performance and a lot of things on the application side; but it would be nice to make everything possible on the framework side to create that culture around every lift app =) So I wanted to throw that idea here and see how to help in this matter.

[Lift] Re: Actor and clusters?
Refering to why i want to know this: Im using stax because it's free, they are pretty cool and lift/scala worked out of the box pretty fast(i was having some issues getting some hosting for whatever i do in my free time with lift/scala). They have a cluster option right now(still, free) so, they are not the best machines in the world but it allowed me to play with cluster information. No, I don't have a production application that needs to scale to many boxes ATM... but I sure have a lot of curiosity of how things work! Once you get to the 100+ pages per second range, call me and we'll figure out how to distribute your app across more than 1 server. I will keep this mail stored in my secure mail secret location as insurance! hahaha On Jul 10, 6:58 am, David Pollak feeder.of.the.be...@gmail.com wrote: On Fri, Jul 10, 2009 at 6:50 AM, David Pollak feeder.of.the.be...@gmail.com wrote: On Fri, Jul 10, 2009 at 12:40 AM, DFectuoso santiago1...@gmail.comwrote: Thanks, that was very useful, to enable sticky variables i would do something like (explain here http://wiki.stax.net/w/index.php/Application_Clustering ) that? So bottom line? An actor can send a message an actor that is living in another JVM Scala's remote actors are very, very fragile and have not been used in any kind of production or load environment to my knowledge. They rely of Java's serialization mechanism which has a series of problems (fragile in the face of different class versions on different nodes, the tendency to serialize the world because of references to globals, and the unsolved problem of serializing Scala singleton objects). I'm addressing these issues with Goat Rodeo (http://goatrodeo.org), but it won't be ready for other people to mess with for a couple of months. And a follow up... what kind of application do you have that requires more throughput than a single JVM can handle? In benchmarks that I've done, a big RDBMS gets saturated around the same time that a single Lift app gets saturated. A big RDBMS can handle about 10K requests per second if most of those requests are reads and they come from cache. If you have ACID enabled (so every write goes to disk), best case is 2K writes per second. A well tuned Lift app can serve 2K dynamically generated pages on a quad core box. If each page has a couple of read queries and a write query, you're pretty close to saturating you RDBMS. So, unless you're at Twitter/Facebook/LinkedIn levels of traffic, you'd be best designing your app for a single JVM.

[Lift] Pick n random elements from a list?
Hi!
I have a list, lets say its List.range(1,100) and i want to pick n
random elements from it.
Basicly I know that i can create n diferente randon numbers inside the
limits and pick each element, but that would look something like this
store List.range(1,100);
store randonNumbers generated by a function;
foreach(randonNumber){
get number from the list into a new list
So before I started coding that, i decided I need to stop thinking in
php and start thinking in scala, i want a code that looks like
List.range(1,100).shuffle take n
So i did some poking around in scala and found that scala 2.8 theres a
util.Random.shuffle so i could do
util.Random.shuffle(List.range(1,100)) take 3
Close enought... but... it doesnt work in lift using scala 2.7.5
So before spending more time I wanted to check if you guys had a quick
way to do this the scala way
Thanks!

}
Compiler:

Finally, dropping the lazzy:

}
Compiler:
(fragment of overrideTest.scala):10: error: error overriding lazy

So this is my trouble(i get all this cases if i try to override

drop the lazy, i cant use super in lazy so what am I doing something
wrong?

If I do something like:

The compiler tells me that super cannot be used in this context. If I
dont user super, then it says that its a recursive declaration(and it
seems to be). How can you achieve this overriding?

[Lift] So, how to get from format to hosting a lift app?
I'm having a lot of trouble getting some code into production in my wiredtree VPS where i use apache and other stuff; so I decided to leave that host alone. I started playing with comet and some dispatch hacks that dont work on the GAE; so I decided to leave GAE alone. So I need a new hosting to run a couple of lift apps that I will be creating in the next weeks! I checked out SliceHost and it seems pretty cool, cheap and hard to configure, so... David said he prefers to use nginx and then jetty. I have no idea how to install, configure and deploy multiple apps in multiple domains in a webserver that only haves the OS installed(which I think is the case of slicehost). So, my first question would be if you know of a better hosting than slicehost. Anyway if I go with slicehost, what OS should I use? What do i need to install to have nginx and jetty running all the time with multiple apps and domains? How do I deploy? (ssh?, ftp? what?)

Well i went ahead and learn a lot from the lift-openId implementation and understand what I would need to do have lift-OAuth working It seems like i could do two things: 1) Get a OAuth java library that allows me to post, get, login and logout then create a OAuth.scala file where i create a trait of the OAuth Handler that would access to this methods, then create a object that extends from that trait; Then create a OAuthProtoUser.scala where I would have a trait for the MetaOAuthProtoUser with the Xhtml for login, override the menus that i would not use and perform the login and logout of the user as well as the post and get methods. Finally create a trait for the OAuthProtoUser that would allow me to store information about the user. 2) Go ahead and have the login,logout, post and get methods on the OAuth.scala actually do the logic to get the tokens without a java library, this would mean creating some way of signing a url and body to post and get stuff from the request, access and user-auth Token Url or an url in the service. I have absolutely no experience with scala, java or lift but I really want to get some(by doing this type of stuff). So what do you think is better(for me to learn, for lift and for you). Also, what part of this abstraction(and how) is the one to set the consumer_key, secret_key and the request urls? Finally; a uber noob question, what is the equivalent of curl(php) or urllib/urlopen(python) that i would use in the second option to actually make the http request to ther other site? I think its a servlet but some trivial example on this would really help me =) On Jun 21, 7:18 am, marius d. marius.dan...@gmail.com wrote: OAuth is not implemented yet in Lift still the project folder is there.

[Lift] Re: So where is that OAuth?
Well i will start working on that tonight(after work of course) and keep you guys updated! Cheers!

Essentially a wrapper over their Java library. 2) Go ahead and have the login,logout, post and get methods on the OAuth.scala actually do the logic to get the tokens without a java library, this would mean creating some way of signing a url and body to post and get stuff from the request, access and user-auth Token Url or an url in the service.

I think it would be a good exercise. Once you're done with it we could probably review it and maybe it'll get its way into Lift if some committer doesn't implement it in the mean time, but regardless would be a good exercise for you. Also, what part of this abstraction(and how) is the one to set the consumer_key, secret_key and the request urls? In OAuth world consumer secret and consumer key are somehow invariants as they impersonate a trusted service. So I would put them into a Scala object where user can just set these quantities from Boot. Finally; a uber noob question, what is the equivalent of curl(php) or urllib/urlopen(python) that i would use in the second option to actually make the http request to ther other site? I think its a servlet but some trivial example on this would really help me =) You can just use HttpUrlConnection, or Apache Http client.

[Lift] Re: Jetty and Apache
Thank you very much, i will look into nginx! I admire how fast you answer everything in here =) ... o yea and thanks for creating this great community! How about the java container, do you strongly recommend jetty or is there anything better? (Specially what do you think of tomcat?)

[Lift] Re: Jetty and Apache
Actually... what can I do to help you create a good tutorial on how to take any off the shelf vpn server running a LAMP stack to have nginx, jetty and apache running(and still using cpanel and everything else for php sites). I think that having a step by step tutorial on how to deploy to the GAE(i know you dont like it but hey), vpn, and Amazon EC2 would be great; I know there are some stuff out there but for people who have not used any java container its pretty hard to undertand what going on with all this softwares Kudos On Jun 20, 6:27 pm, David Pollak feeder.of.the.be...@gmail.com wrote: Apache does not deal well with long polling or lots of open connections.

[Lift] Very basic questions
Hi! I'm starting to use lift/scala(I don't know either) and already I have a couple of (very very basic) questions. I'm reading The definitive guide to lift and even tho it's been enough to actually understand some of the key elements of a lift application I am having some problems understanding some of the code and how you people work with Lift. 1.- What tools do you use to program, debug and run the website? At this moment I'm using text mate to program and the terminal to run yetti; It's very slow to run yetti every time and its hard to understand the errors so i tried eclipse but I had trouble installing the maven plug-in so... what is your toolbox? 2.- What is _ and Full in different places? I see that in a binding name - SHtml.text(name, name = _) or when checking for cases there's a case for Full(_) and for _ ; what does _ means and what does Full mean; and whats the difference between Full (_) and _. 3.-Reading about the flow from request to response; i cant avoid to ask: How many times does the Boot(or bootloader) run? Once when i run the app(or web server; yetti in my case) or once every time there's a request?
