Re: [Lift] Re: Call it Lift 2.0
Interesting - this is something i've not actually thought about: If we were to compile a list of all the breaking changes in 1.1, perhaps that would give some focus to this discussion... as josh points out, there are most likely quite a few now and 1.0 - 1.1 is a fairly short jump. Loc and LocParam Actor - LiftActor Full,Box etc have moved packages JSON parsing alterations and changes in JsExp Im probably missing a number of others, but we are talking about some fairly significant breaks here, right?

If not, I would argue a bigger version jump than 1.1. The current Lift is not source compatible with 1.0.x, just consider Box moved from ...util to ...common. Hence you would go for 2.0, right? Also, there is the possibility of taking the version system and adding a functionality milestone version at the begginning. In this case, you can use that number for marketting purposes (e.g. Lift goes 1.0!). Your version number would then be Marketing.SourceCompatability.All but Trait BinaryCompatability.Binary Compatibility. I am all against using versioning policy for marketing!

Folks,
The 280_port of Lift properly compiles and runs the Lift demo application
against the Scala 2.8.0 nightly.
I spent most of today tracking down a bug that I can't reproduce in
isolation, but it seems that the ensureCapacity method in Scala's
StringBuilder method has an infinite:
def ensureCapacity(n: Int) {
117http://lampsvn.epfl.ch/trac/scala/browser/scala/trunk/src/library/scala/collection/mutable/StringBuilder.scala?view=markup#L117
if (n array.length) {
118http://lampsvn.epfl.ch/trac/scala/browser/scala/trunk/src/library/scala/collection/mutable/StringBuilder.scala?view=markup#L118
var newsize = array.length * 2
119http://lampsvn.epfl.ch/trac/scala/browser/scala/trunk/src/library/scala/collection/mutable/StringBuilder.scala?view=markup#L119
while (n newsize)
120http://lampsvn.epfl.ch/trac/scala/browser/scala/trunk/src/library/scala/collection/mutable/StringBuilder.scala?view=markup#L120
newsize = newsize * 2
121http://lampsvn.epfl.ch/trac/scala/browser/scala/trunk/src/library/scala/collection/mutable/StringBuilder.scala?view=markup#L121
val newar = new Array[Char](newsize)
122http://lampsvn.epfl.ch/trac/scala/browser/scala/trunk/src/library/scala/collection/mutable/StringBuilder.scala?view=markup#L122
arraycopy(array, 0, newar, 0, count)
123http://lampsvn.epfl.ch/trac/scala/browser/scala/trunk/src/library/scala/collection/mutable/StringBuilder.scala?view=markup#L123
array = newar
124http://lampsvn.epfl.ch/trac/scala/browser/scala/trunk/src/library/scala/collection/mutable/StringBuilder.scala?view=markup#L124
}
125http://lampsvn.epfl.ch/trac/scala/browser/scala/trunk/src/library/scala/collection/mutable/StringBuilder.scala?view=markup#L125
}
I saw an infinite loop in lines 119/120 (it was line 115 in the version I
was testing against). I replaced Scala's StringBuilder with the Java native
code and all worked just fine. It might be worth a gander at the byte-code
for StringBuilder to see how an infinite loop could happen.
Anyway, I'm looking forward to the next drop of a stable 2.8.0 so I can
compile against Specs and get a more complete (read: passes tests... right
now the tests are commented out because I don't have the
Specs/ScalaCheck/etc. chain in the 2.8.0 nightly).
Thanks,
David

Re: [Lift] Re: session variable question
Jack, No, you don't call that yourself - I was meaning that Lift initiates the session for you, thats not your worry :-) My point really was that comet actors and other lift infrastructure initiate the session, but normal scala actors would require you to start the session scope manually using S.initIfUninited ;-) Basically, dont worry about it - just use the SessionVar extension and you should be good to go.

I saw an infinite loop in lines 119/120 (it was line 115 in the
version I was testing against). I replaced Scala's StringBuilder
with the Java native code and all worked just fine. It might be
worth a gander at the byte-code for StringBuilder to see how an
infinite loop could happen.
Anyway, I'm looking forward to the next drop of a stable 2.8.0 so
I can compile against Specs and get a more complete (read: passes
tests... right now the tests are commented out because I don't
have the Specs/ScalaCheck/etc. chain in the 2.8.0 nightly).
Thanks,
David

It should be just fine. You can tell lift to not use Ajax or any JS at all. There are some flags in LiftRules to do that.

[Lift] Combined primary key?
Hi all I can't seem to find a way to use a combined primary key. The use case I'm looking at would be something like a bug tracker where you can comment on each bug. Each comment would have a number (only unique within each bug report). In SQL I'd write something like: CREATE TABLE bug_comments ( bugid integer REFERENCES bugs (id), number integer, comment text, PRIMARY KEY (bugid, number) ) I've seen that I can enforce the uniqueness of (bugid, number) with def dbIndexes = Index (bugid, number) :: super.dbIndexes I'd like to have the comments numbered 1..n in each bug so they can be easily referenced. What is the common way to do this in Lift? Should I try to go that way or would you abandon the combined primary key and simply use a synthetic primary key with LongKeyedMapper with IdPK?

Nginx only comes with a round-robin balancer and a hash-based balancer, so if a request takes a while to load, Nginx will start routing requests to backends that are already processing requests -- as a result, some backends will be queueing up requests while some backends will remain idle. You will get an uneven load distribution, and the unevenness will increase with the amount of load subject to the load-balancer. Haproxy as a LB can: 1: Plenty of load-balancing algorithms, including a least connections strategy that picks the backend with the fewest pending connections. Which happens to be just what we want. 2: Backends can be sanity- and health-checked by URL to avoid routing requests to brain-damaged backends. (It can even stagger these checks to avoid spikes.) 3: Requests can be routed based on all sorts of things: cookies, URL substrings, client IP, etc. So, I use nginx + haproxy + tomcat(jetty).

Hi All,
Yet another question: I need to make Ajax calls when a page is
loaded
or resized. The call would need to pass some local client
information
(browser size). The return should be javascript code that
populates a
div on that page (in particular: an image that is scaled on the
server
to match the browser size). Actually, local js code is in place
that
makes the call only after the user has stopped resizing (using a
timeout).
I guess I have to use AjaxCall, providing an expression that puts
the
window dimensions in an array or list, then return the
javascript to
add an img tag that downloads the scaled image from a generated
url.
Given the level of success I achieved so far, I thought I better
ask
if this would work our before I start trying endlessly.
Thanks for any suggestions,

If not, I would argue a bigger version jump than 1.1. The current Lift is not source compatible with 1.0.x, just consider Box moved from ...util to ...common. Hence you would go for 2.0, right? Also, there is the possibility of taking the version system and adding a functionality milestone version at the begginning. In this case, you can use that number for marketting purposes (e.g. Lift goes 1.0!).

Re: [Lift] NPE in S.?! if used outside a request
I am okay with an NPE thrown from using S outside a request. Yeah, it'd be
nicer to have a more polite error message, but there should be no creep
towards being able to call S outside a request/session scope.
Also, except for tests or actors, one should never think about initializing
S.

2) but if you have one that works app-wide then it should work -- but

It would be nice to catch uses of S.? outside of a request context when
your intended behavior is that you only have per-request locales, so I guess
if that is the desire then one should make their locale calculator log the
error text, and the change to lift should be something more like:
def resourceBundles: List[ResourceBundle] = {
-_resBundle.value match {

+ case _ = {

).openOr(
NamedPF.applyBox((name, locale),
LiftRules.resourceBundleFactories.toList).map(List(_)) openOr Nil
)))
_resBundle.value
}
- case bundles = bundles
}
}
That is, if the _resBundle ThreadGlobal has not been initialized yet, or
it's been initialized with the empty list, then do resource bundle loading.
If it has been initialized with a non-empty list then use that.
I don't think this should interact badly with S.init, since S.init uses
_resBundle.doWith(Nil) ... which will both overwrite any loaded app-level
bundles with the empty list, but also restore them upon completion of the S

Re: [Lift] Working with legacy databases
I think scalajpa is a very good option if your database is supported by the underlying jpa provider. - according to https://www.hibernate.org/80.html, the hibernate / sybase supported version is Sybase 12.5 (JConnect 5.5) - according to https://www.hibernate.org/120.html, there is some Batch update issue with Sybase If you have another database version, you can customize the generated sql writing your own custom Dialect class. A few issues I had : - hibernate + cglib + scala : using a lot of permgen memory, exhausted PermGen memory can cause OutOfMemoryException (solution : add some more PermGen memory with -XX:MaxPermSize) - hibernate + c3po + mysql : issue with connection pool, connections with timeout are reused and issue errors (solution : review code and always call cleanup when necessary) Maybe someone else will provide some info about other JPA providers. You can generate your first scala/jpa web application using the lift-archetype-jpa-basic / 1.1-SNAPSHOT archetype. Don't forget to use http://scala-tools.org/repo-snapshots repository.

has an app wide setting and there is nothing to say that that a user
must implement their locale calculator in a particular way... This is
one of the great things about lift ;-)
So the issue here seems to be the lazy / eager evaluation of bald
rather than localization out of request context? I'm all for getting
rid of these NPE scenarios though :-)

the entire site, I guess), but the NPE seems uglier than providing
an error log explaining the problem.

This is apparently due to S._resBundle being null because S.init has

enclosing scope, and so:
private def ?!(str: String, resBundle: List[ResourceBundle]):

Blows up with NPE. resBundle is passed in from S.? by calling
S.resourceBundles, which is defined thus:

[Lift] Improving lift-flot
I've been working with lift-flot a lot recently and I'd like to share some thoughts and suggest some improvements. It's a very useful interface to a great Javascript plotting library, so consider these as small suggestions from a fan. First, the fact that FlotSerie's data property is a List[Pair[Double, Double]] means that detail about what you're charting can get lost. If you're plotting more than one line and want to refer to a certain FlotSerie later, you have to rely upon the FlotSerie's label and the order of the List[FlotSerie] used by Flot.render and JsFlotAppendData. This can be addressed either by having a parallel list of your own more expressive data instances, which is what I'm doing, or by only having this more expressive list and having an implicit conversion to a Pair[Double, Double] (I just thought of this and haven't tested it). I can't think of a better way to do this, since everyone's data source will be different and so the generic Pair[Double, Double] is needed – this is just a comment on how the library works. There is a general reliance on List[Pair[Double, Double]] throughout lift-flot and it is an actual annoyance when you are updating an existing graph, for instance via a Comet actor. Speaking of the List [FlotSerie] I mentioned earlier, if you are updating your chart you need to keep this list of series around and update it as you have new data to plot. This is fine except for the fact that JsFlotAppendData requires you to pass it both the updated List[FlotSerie] and a List [Pair[Double, Double]] with one and only one new data point for each FlotSerie. This means that you need to hard-code the list order so that the order of the List[Pair[Double, Double]] matches that of the List[FlotSerie], so that the correct series is updated with the correct new point. I assume you need to give it the new data twice so it knows which FlotSeries have new points and which don't, but this is something the library could do behind the scenes to make the developers' lives easier. More importantly, I don't like the fact that the method replies upon two lists being in the exact same order. So, what would I like to see with lift-flot? Mainly I'd like to see the whole situation with the List[Pair[Double, Double]]'s improved. I don't know if another Flot class, such as a FlotPoint, would help or maybe just making better use of the List[FlotSeries], but I think there definitely is room for improvement. If someone else has been using lift-flot I'd love to hear their suggestions, as perhaps I've been making it more complicated than it actually is. I think a lot of the annoyances I described only crop up when using the JsFlotAppendData method, so I don't won't to propose anything that ends up being a regression for the majority of the library's users. Please let me know if you're doing static charts and anything suggested would make your work more complicated. Since I am using lift-flot a lot (perhaps more than anyone else, seeing how little it's been discussed here recently), I'm more than happy to take the lead and contribute some code if others agree that my suggestions are reasonable (please convince me otherwise!). I guess that the first thing I could do would be to write a tutorial on using the library. Would that be appreciated? Peter Robinett PS I've been working with 1.1-M5 and 1.1-M6, but I don't think there have been any changes to lift-flot since then, let alone any that would invalidate my comments. -- You received this message because you are subscribed to the Google Groups Lift group.

Re: [Lift] Problem with issue 182
OK, thinking about this a little further, technically it would be a breaking
change to remove the menus method from MetaMegaProtoUser. Would it be better
to simply introduce a MenuGenerator trait, a la
trait MenuGenerator {
def menus : List[Menu]
}
And add that to CRUDify and MetaMegaProtoUser?

On 11月22日, 上午4時46分, Ross Mellgren dri...@gmail.com wrote:
In the recent thread, a couple people asked for the ability to create
dynamic menu items per request from the database. David suggested
Loc.supplimentalKidMenuItems which works fine for dynamic children of a
static menu, but doesn't support the ability to make the top level menu
dynamic.
Menu has a method called makeMenuItem which gives a Box of MenuItem. What
about a new method makeMenuItems that gives a possible plurality of
MenuItems whose default implementation deferred to the existing makeMenuItem
in the case where it's not overridden? I made this change to my local copy
of lift and it seems to work alright.
Example Menu:
case class DynMenu() extends Menu(Loc(dynmenu, Link(List(dynmenu), true,
/dynmenu), Dynamic Menu)) {
override def makeMenuItems(path: List[Loc[_]]): Iterable[MenuItem] =
DynMenuItem.findAll.map(dmi = {
MenuItem(Text(dmi.label.is), Text(dmi.link.is), Nil, false,
false, Nil)
})
}
That is, a Menu can generate 0 or more MenuItems when the menu is being
generated. The disadvantage I see is similar to the one with
supplimentalKidMenuItems -- that is, you have to manually compute the
attributes of MenuItem such as current. However, it does give you the full
power to make whatever kind of menu items you want.
I looked briefly at seeing if it would be feasible to use a function
Box[Req] = SiteMap on LiftRules, but I think the RewritePF auto detection
thing in LiftRules.setSiteMap prevents this from being the right thing.

Give me a few days to respond please.

In the recent thread, a couple people asked for the ability to create
dynamic menu items per request from the database. David suggested
Loc.supplimentalKidMenuItems which works fine for dynamic children of a
static menu, but doesn't support the ability to make the top level menu
dynamic.
Menu has a method called makeMenuItem which gives a Box of MenuItem.
What about a new method makeMenuItems that gives a possible plurality of
MenuItems whose default implementation deferred to the existing makeMenuItem
in the case where it's not overridden? I made this change to my local copy
of lift and it seems to work alright.
Example Menu:
case class DynMenu() extends Menu(Loc(dynmenu, Link(List(dynmenu),
true, /dynmenu), Dynamic Menu)) {
override def makeMenuItems(path: List[Loc[_]]): Iterable[MenuItem] =
DynMenuItem.findAll.map(dmi = {
MenuItem(Text(dmi.label.is), Text(dmi.link.is), Nil, false,
false, Nil)
})
}
That is, a Menu can generate 0 or more MenuItems when the menu is being
generated. The disadvantage I see is similar to the one with
supplimentalKidMenuItems -- that is, you have to manually compute the
attributes of MenuItem such as current. However, it does give you the full
power to make whatever kind of menu items you want.
I looked briefly at seeing if it would be feasible to use a function
Box[Req] = SiteMap on LiftRules, but I think the RewritePF auto detection
thing in LiftRules.setSiteMap prevents this from being the right thing.

[Lift] Need for lift application to coexist with spring in the same webapp
Hi David, Thank for all the help so far. My lift application needs to coexist with the spring servlet in the same web application. I have configured the web.xml file for both of the spring servlet and lift filter. Hence I need to configure the url pattern in such a way that /grid/* request will be handled by lift application and other urls will be processed by spring. What I need to understand is how to set up the rules such that this can be achieved. -- You received this message because you are subscribed to the Google Groups Lift group.

Re: [Lift] Feature Request: deleteMenuLocParams in CRUDify
Added an issue for you:
http://github.com/dpp/liftweb/issues#issue/205
and it's on review board:
http://reviewboard.liftweb.net/r/121/
So it will (probably) be in 1.1-SNAPSHOT in a day or two, assuming the change
isn't unacceptable for whatever reason.

HI,
I generate a form with .toForm and want some fields to not appear in the

I have tried to subclass fieldOrder in the MetaMapper but while it controls

the list returned by the overrided fieldOrder methods.
I have tried other methods but with no luck.
