Re: Images in server folder (store and access)

ClientBundle; Best Practices
While planning a new Application I'm trying to figure out how to best
design it to get the most out of the whole ClientBundle thing.
But I'm trying to figure out how to use the bundles in ways that they
(1) were intended to be and (2) that fit my needs;
* Is the goal to have a single Resource class at the top-level
that inherits all the resources used by that application?
Is there some penalty to having separate resources created with
GWT.create?
* For CSS, should my app inject the CSS or should the users of
the resource do that themselves using #ensureInjected() ?
* Is there a good way of styling a Widget in different ways,
but still using a single top-level resource?
Think a WindowPanel and a DialogPanel, both inherits a popup
panel but wants to style it differently;
interface WindowResources extends PopupResources {
}
interface DialogResources extends PopupResources {
}
interface AppResources extends WindowResources,
DialogResources {
...
}
If a top-level resource like AppResource can't inherit
both WindowResources and DialogResources, how would one
structure the resources so that WindowPanel and DialogPanel
can have their separate looks?
* If you want to style your application differently than
the default GWT look, you fork the theme module and alter
the CSS to fit your needs. Possible you add some extra
style-names to some of your widgets. All and all, it's
quite simple to change the appearance of the standard
widgets.
How will this work with client bundles in the future?
Will all standard Widgets accept a Resource class as
first constructor argument? And if you want a different
look to your application, you need always to pass
resources around?
Thanks

Using external styles with UiBinder error
I started using the UiBinder for various forms in my application. I
have created a UiStyles.css (with a CssResource interface called Css)
under the main client package and would like to use that in all
packages across the application. The problem is I am using a sprite in
the stylesheet for a background image as:
@sprite .datebox { gwt-image:calendar; width : 150px !important;
height : 24px !important; padding : 2px; background-position : right
center !important; }
and I refer to the stylesheet in the ui.xml as:
ui:style src='../UiStyles.css' /
and for the sprite I have the following line in the ui.xml :
ui:image field=calendar src='../StaticResources/images/
calendar.png' /
Now I thought I should only need this in the ui.xml file that is using
the .datebox style. But I see that if I refer to the UiStyles.css in
any ui.xml (even if it does use the above sprite), it requires the
ui:image field=calendar src='../StaticResources/images/
calendar.png' /
otherwise it fails to compile

Re: Getting error $doc.getBoxObjectFor is not a function in Firefox 3.6
Resolved this in GWT 1.4 (we're version locked due to WAS 6.0) by modifying the com/google/gwt/user/client/impl/DOMImplMozilla.java file in gwt-user.jar. I assume a similar strategy would work in later versions of GWT. Replace the implementations of the getAbsoluteLeft and getAbsoluteTop methods with: return elem.getBoundingClientRect().left - $doc.documentElement.getBoundingClientRect().left; and return elem.getBoundingClientRect().top - $doc.documentElement.getBoundingClientRect().top; respectively.

Re: Local events dispatch/handling. Don't wanna go through the EventBus...
I don't see any reason why the TabPresenter can't listen for events on the main event bus. People talk about not wanting to crowd the event bus. I'm not sure what they mean by this, though I can think of three things: 1. Volume of events 2. Diversity of event types 3. Number of registered event handlers For the first one, you have to remember that you're running in Javascript in a web browser. When you post an event to the event bus, it gets processed and all listeners are notified immediately, in series. The event bus isn't holding on to events until some processing thread wakes up to process them, so there's never a backlog of events to process. Incidentally, you also have to keep this in mind when choosing the order of events when you have multiple events to fire. When it comes to diversity of event types, handlers are registered for particular event types and are put into different buckets based on that type. When the event bus goes to choose the handlers, it knows the event type and can locate them quickly. Before moving to HandlerManager, I wrote my own event bus that was simply a HashMap of event type to Collection of handlers. Looking at the source for HandlerManager, that's exactly what it does as well. Assuming GWT's Javascript implementation of HashMap is reasonably efficient, having handlers for many different types of events shouldn't be a problem. As for the number of event handlers registered, that shouldn't actually get too out of control in practice. No matter how large the application is, the scope of what the event bus needs to handle at any one time is limited to what's displayed in the browser at one time. If a view is hidden, it shouldn't have any handlers registered (aside from maybe a place change handler). This is addressed during the Q A of Ray Ryan's Google I/O talk (around 46:00 - 49:00) and Ray's answers are excellent. To reiterate one very important part of that (as I don't feel it's emphasized enough): you always have to be careful to unregister any handlers when they become irrelevant (such as when a view is dismissed or replaced with a different view). As long as you do that, the size of the application becomes largely irrelevant. There are two cases I can think of where having a separate event bus might be useful: 1. Prioritizing event delivery 2. Automatic clean-up of event handlers When using a single HandlerManager, you don't have much control over the order that event handlers are notified; it depends entirely on the order in which they were added and whether the HandlerManager instance is configured to fire handlers in reverse order. If you have a local event and you want to make sure that, for example, the related view gets first stab at it, you could create a local event bus that will automatically propagate the event to the global event bus where the less important handlers are registered. I think that these cases would be rare, and you can get the same effect by chaining two events/ handlers rather than two event busses. Finally, it would be nice if you could create a local HandlerManager that would clean up all of its handlers automatically when the view changes. I don't think that the current HandlerManager implementation does anything like this. It could probably be done, but would still require discipline to explicitly deconstruct HandlerManager instances when they're no longer needed. Plus, it could be confusing for the object owning the handler for it to be implicitly unregistered. -Brian On Jan 29, 5:05 am, Abdullah Shaikh abdullah.shaik...@gmail.com wrote: Hi Thomas, I understand EventBus is for decoupling things .. but I guess there are sometimes where you would want to use multiple (local) event bus. I don't know may be I am missing something .. let me explain you my case I have a DockPanel where I have added Widgets (panels) on West, Center East directions. The panel on the west side contains navigation links and when clicked the content is displayed on the center panel. I was able to do the above navigation displaying because the DockPanel was the part of main presenter/view and I could easily access the DockPanel and change the content of center panel. But there is a time when I have a TabPresenter (which has a Tabpanel) into my center panel, and in the first panel of TabPanel there is a button which should fetch some data from server and display it in the second panel of TabPanel. Now if I do this using the app wide EventBus bus, I won't have access to the TabPanel because it's inside of TabPresenter, in the app wide EventBus I could only create TabPresenter and add it to center panel but cant access TabPanel. or should I have getTabPanel in Dispay of TabPresenter and manipulate it in app wide eventbus ? I don't think this should be done like this. a local EventBus which will be a part of TabPresenter will be good for this case I guess. - Abdullah On Fri, Jan 29, 2010 at 3:00 PM, Thomas Broyer

Re: Source code availability to the GWT Compiler
We also use the Maven sources JAR approach. The .class and .java do NOT have to be in the same JAR file. The GWT compiler will just need the sources JAR on the classpath, which you can accomplish via Maven dependency management, as you have stated. The only problem I found using the Maven provided scope is that provided scope is currently not transitive. So if you have project A depend on project B, which depends on project C, and project C builds a sources JAR for GWT, then you can't use provided scope if you want the GWT compile to happen with project A. To work around this, we simply use excludes to prevent the sources JARs from being included in the final WAR. Also note that if you build test JARs, test dependencies are not transitive. There is a JIRA issue to fix this: http://jira.codehaus.org/browse/MNG-1378. -Richard On Feb 5, 4:09 pm, Micah mkwhita...@gmail.com wrote: I acknowledge that the source needs to be available for the gwt compiler but I still question if the source needs to be in the same jar as the compiled endstates you'd ship to a client.

I guess I'm asking in general as opposed to specifically using the gwt-maven-plugin. I'm still testing this out but it seems like it should work as long as a jar with the source code is on the classpath. The approach I'm trying to take is to follow themavenstandard of producing a *-sources.jar during the build of the first module. Then all consuming modules will list the standard jar as a compile scoped dependency and thesourcesjar as a provided scoped dependency.

Generalpath
I have an AWT application that draws some products using lines and arcs, fills, etc (java2d stuff) and creates a GeneralPath that ultimately gets drawn in the Swing JPanel (presentation layer). If the UI of the application is all written in GWT (instead of swing, and use GWT RPC for communication with the server side AWT services), can the server side (awt code) still create the same GeneralPath and have the GWT UI draw it (similar to d.draw(myDrawing))? If not what would the solution be? I need to see how easy will this be before jumping into a GWT conversion project. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Local events dispatch/handling. Don't wanna go through the EventBus...
I also don't like the EventBus approach. In my opinion, it decouples exactly the wrong things: While it acts like something you can just throw events onto, and you don't have to care who will handle them, in the end you actually do care. So the coupling is invisible, but logically it's still there. Things get really nasty, as soon as event handlers have to be coordinated (meaning they're not 100% independent). The 'fireInReverseOrder' field of the HandlerManager class is symptomatic. What we've got here is basically a publisher subscriber pattern, which is a great pattern, if and only if the publisher and all subscribers are absolutely independent (like in a message feed). But with GUIs that's very often not the case. So instead of using an EventBus, I'd do the following: Introduce an 'Operation' interface, and inject operations into your presenters. The presenter then binds these operations. So you get decoupling, testability [*], and allows for much better static analysis of your code. In the projects that I've tried both approaches (non-GWT projects), I found the difference is huge, especially when you encounter a bug. Chris [*] Note: Avoids the ServiceLocator pattern, so it doesn't violate the law of demeter http://en.wikipedia.org/wiki/Law_Of_Demeter . The EventBus basically plays the role of a ServiceLocator from the sender's and receiver's point of view. You don't really know what's in there, and you use the EventBus to get the thing that you actually want indirectly. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT 2.0.1 + Low Level API of GAE
Hi. GWT is not directly related to the GAE datastore, but I assume you mean that you want to be able to pass entities between client and server.

Re: ScrollPanel (scrollbar) CSS
It's simply because there's no style in standard .css.
Anyway a scroll panel is simply a div with overflow set to scroll.
It's not css standard to be able to customize it... I didn't pay attention
to what widget you wanted to customize, I simply explained how we customize
a widget in general.

Right.So this is how ClickHandler implementation can be registered.
Ok, suppose I use TextBox instad of button. HOW will the framework

How this thing work? It's NOT based on same type of method argument of

it?
Well, almost.
In brief, ClickEvent links to ClickHandler (it extends
DomEventClickHandler), so UiBinder makes a call to addClickHandler
(yes, AFAICT, it just prepends an add in front of the handler's
class name).

My UI will now throw exceptions regularly, although not consistently, nevertheless leading me to a situation where I have to wrap every widget creation code in try/catch to prevent the Javascript interpreter from falling over.

Re: Facebook
Yes, I have. You can play with it: http://www.mobca.st/ There are two sides to a facebook webapp, the client and the server. On the GWT side you will not be using facebook-java-api or any other java http-based client. You will use the facebook connect library through JSNI. The new api library is quite easy to use from GWT: http://github.com/facebook/connect-js On the server side, throw facebook-java-api in the trash. It's horrid. The Facebook API, while kludgy as hell, is actually pretty straightforward. Just make HTTP requests and parse the results with your favorite JSON or XML parser (I use Jackson).

Firefox ONPASTE: Get the text to be pasted?
I'm in the process of implementing a text control from Swing
(JFormattedTextField) to GWT. One of the requirements is that when
the user pastes in a block of text, I can't just let the default
action occur; I have to filter the text through a mask. Given that
requirement, I need to be able to intercept the text the user is about
to paste into a TextBox.
I've got a solution that seems to be working perfectly in IE and
WebKit (Chrome/Safari). There's an open Mozilla bug requesting this
feature (https://bugzilla.mozilla.org/show_bug.cgi?id=407983), but
it's not clear when it will be resolved.
Here's what I have so far, plugged in to the StockWatcher sample app
for ease of testing. Does anyone know of a reliable way to make this
work in Firefox?
(1) Create the nameField TextBox like this:
final TextBox nameField = new TextBox()
{
@Override
public void onBrowserEvent(Event event)
{
super.onBrowserEvent(event);
switch (event.getTypeInt())
{
case Event.ONPASTE:
{
event.preventDefault();
String text = getPastedText(event);
if (text.length() 0)
{
Window.alert(Pasted: +text);
}
break;
}
}
}
};
nameField.sinkEvents(Event.ONPASTE);
(2) Add this methodt:
public static native String getPastedText(Event event)
/*-{
var text = ;
if (event.clipboardData) // WebKit/Chrome/Safari
{
try
{
text = event.clipboardData.getData(Text);
return text;
}
catch (e)
{
// Hmm, that didn't work.
}
}
if ($wnd.clipboardData) // IE
{
try
{
text = $wnd.clipboardData.getData(Text);
return text;
}
catch (e)
{
// Hmm, that didn't work.
}
}
// Ok, last chance. Firefox refuses to make this easy:
// https://bugzilla.mozilla.org/show_bug.cgi?id=407983
// And this ridiculous approach is unlikely to work.
// But try it anyway; we have nothing to lose.
// We can ignore Opera; it doesn't even fire ONPASTE.
try
{
if (netscape.security.PrivilegeManager.enablePrivilege)
{
netscape.security.PrivilegeManager.enablePrivilege(UniversalXPConnect);
}
else
{
return ;
}
}
catch (ex)
{
return ;
}
var clip = Components.classes[@mozilla.org/widget/clipboard;
1].getService(Components.interfaces.nsIClipboard);
if (!clip) return ;
var trans = Components.classes[@mozilla.org/widget/
transferable;
1].createInstance(Components.interfaces.nsITransferable);
if (!trans) return ;
trans.addDataFlavor(text/unicode);
clip.getData(trans, clip.kGlobalClipboard);
var str = new Object();
var strLength = new Object();
trans.getTransferData(text/unicode, str, strLength);
if (str) str =
str.value.QueryInterface(Components.interfaces.nsISupportsString);
if (str) text = str.data.substring(0, strLength.value / 2);
return text;
}-*/;

[ANN] Objectify-Appengine 2.0, easily use GWT with the GAE datastore
A couple days ago the Objectify team released version 2.0 of Objectify-Appengine, a mid-level open-source data persistence tier for Google App Engine. It's a comfortable level of abstraction somewhere between JDO's too complicated and the Low-Level API's too simple, allowing you to easily put(), get(), delete(), and query() your own typed objects. Why am I posting about it here? One of Objectify's goals has been to make it easier to work with GWT. In Objectify v2, all of the datastore basic types (Key, Email, Link, GeoPt, Category, Rating, etc) are made available to your GWT code. So: * You can pass your entity classes back and forth through GWT-RPC without DTOs, detaching, or any other magic. Even if you choose to use JDO or other persistence APIs, you can still use the Objectify GWT module to GWT-enable the datastore types. Objectify is a ~100k jar with no dependencies. Just add the jar to your project and this to your module: inherits name=com.googlecode.objectify.Objectify / You can find more information about Objectify here: http://code.google.com/p/objectify-appengine/ You can find specific information about using Objectify with GWT here: http://code.google.com/p/objectify-appengine/wiki/ObjectifyWithGWT Thanks, The Objectify-Appengine Team -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Using external styles with UiBinder error
Why not reference your styles from a CssResource that itself is wrapped in a
ClientBundle? Something like:
*Resources.java*
public interface Resources extends ClientBundle {
public static final Resources INSTANCE = GWT.create(Resources.class);
@Source(UiStyles.css)
public MyUiStyles uiStylesCss();
@Source(calendar.png)
public ImageResource calendar();
}
*MyUiStyles.java*
*
public interface ImagesDialogCss extends CssResource {
public String datebox();
}
*
*
*
*MyDialog.ui.xml*
ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'
ui:with field='resources' type='com.google.gwt.sample.client.Resources'/
g:VerticalPanel
g:Image addStyleNames='{resources.uiStylesCss.datebox}'
ui:field='someFieldId' /
/g:VerticalPanel
/ui:UiBinder
I might be overlooking some details, but you should be able to use the above
to share your UiStyles.css w/o having to declare an associated ui:image
element all over the place.

Re: Generalpath
You would need to look at the graphics solutions for GWT (svg/canvas/ vml/flash). As there is no native (nonFlash/plugin) corssbrowser methods you would need to either look at a gwt library or wrap an existing javascript solution for graphics. But I would instead inspect your ui, because a lot of your code may be done with CSS or html. You probably will not be able to maintain the same structure as awt, swt, swing, etc are not compatible with GWT (as in not implemented).

Building GWT apps that support adjustable font sizes
Hi, I need to build an app that also works well (meaning: looks acceptable and is still usable) with different font sizes. Eg. a user with impaired vision might increase the default font size of the browser to make web pages easier readable for him. For me as a developer this means removing as many fixed sizes in my layout as possible. This seems kind of hard as a lot of the layouts, also the new ones like LayoutPanel and DockLayoutPanel use fixed sizes and do not dynamically adjust to the size of their content. As a test I increased the default font size and looked at the mail sample and it looks very unpleasant and unusable (overlapping elements). Do you have some tips/guidelines/rules how to achieve such a task? Which layouts to use, which to avoid? How to avoid overlappings? Any other tricks?

RPC with ArrayList, another hapless Ray Ryan groupie reaches out for help
Hi
Trying to build out the Ray Ryan best practices sample in GWT 2.0 ,
having trouble with the action(command)/response objects, containing
array list instances. This is Ray's sample
package com.play.client;
import java.util.ArrayList;
public class GetDetails implements ActionGetDetailsResponse {
private final ArrayListContactDetailId ids;
public GetDetails(ArrayListContactDetailId ids){
this.ids = ids;
}
public ArrayListContactDetailId getIds(){
return ids;
}
}
This is my latest try..
public class GetDetailsAction implements ActionGetDetailsResponse,
IsSerializable {
private ArrayListContactDetailId ids;
public GetDetailsAction(){
}
public GetDetailsAction(ArrayListContactDetailId ids){
this.ids = ids;
}
public ArrayListContactDetailId getIds(){
return ids;
}
}
public class ContactDetailId implements IsSerializable{
private String id;
public ContactDetailId(String id){
this.id = id;
}
public String getId(){
return id;
}
}
To Explain my changes, I have:-
* Changed the name because I felt like it
* Added a no-parameter constructor because [ERROR] [testgwt]
com.play.client.ActionT has no available instantiable subtypes.
(reached via com.play.client.ActionT)
* Removed the final modifier from the id's intance member because
'[WARN] [testgwt] Field 'private final
java.util.ArrayListcom.play.client.ContactDetailId ids' will not be
serialized because it is final'
My sample runs but I now get a
com.google.gwt.user.client.rpc.SerializationException when I try to
pass an action instance via RPC as per the talk...
Any Clues? Have I missed some embarrassing and obvious point? All of
the 'reference' implementations pass simple types and skirt the
ArrayList thing.

[gwt-contrib] GWT 2.0.2
Hi, Any idea when there will be a GWT 2.0.2 ? The 2.0.1 contains a few issues that stops us from migrating (already reported and fixed), the 2.0 contains issues that were fixed in 2.0.1 ... so we must migrate. building our own version is not immediatly possible. David -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
Re: [gwt-contrib] Re: Add the ability to change the default HandlerManager of a Widget
Thinking outload... What about allowing ctors to take a HM. The other ctors use the default implementation. If you dont care for a HM then use the ctors without HM in the parameter list. That way The problem with this is that you then have to add HM to the ctor for every extension of Widget (which are many). you dont pollute the widget method list with gets/creates and sets Well, I think the current consensus is that gets and sets won't happen/aren't necessary for the use case in question. As far as polluting the Widget method list with createHM()... It is a protected method with a default implementation, so 1) You would have to extend Widget (or one of widget's subclasses) to see it. 2) You probably wouldn't see it unless you were purposefully looking for things to extend about Widget which prolly dont make sense once the thing is built. Since the HandlerManager is lazy loading (with good reason, too) the only way this sort of flexible API makes sense is to (1) provide a factory method or (2) allow for a HMFactory in the constructor. I tend towards the factory method because it is a less complex change and because of the problems with constructor extensions mentioned above. -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
[gwt-contrib] Re: Add the ability to change the default HandlerManager of a Widget
Updated the patch to only add a createHandlerManager which gets called
by ensureHandlers.

Alright, lets go with createHandlerManager() for now. Thanks for all the
feedback.
@sven -
Would you like to update the patch by reverting the getHandlerManager()
method back to a package protected method? If you don't get to it for a few
days, I'll can do it for you.
Thanks,

I'd say that if you wanted to implement a HandlerManager stack, it
would probably be best to do that internal to the HandlerManager,
rather than forcing a Widget to know how events are handled.
Assuming that is possible given the current Widget implementations
(others more expert than I would know this, probably), the only API I
would want is createHandlerManager(). I could then manage how that
more complex HandlerManager is dealt with.
While we're on the subject... if you're providing this factory method,
I would rather see a well-documented interface to implement rather
than a semi-documented implementation of which I would probably be
overriding every method.

This conversation keeps getting complicated by discussions of policy. I'm
just trying to make it possible for widgets we haven't thought of yet to
define policies of their own.
E.g., to temporarily switch between modes that change the set of events
they
source, copying some handlers or not if that's appropriate (perhaps in
mode
B I simply am not a source of the events that would happen in mode A.
Perhaps I am. Let me choose). E.g., to implement an HM stack. E.g., to
try
out a singleton HM (I wouldn't, but why should I stop you from trying it
out).
I think JohnL has hit the sweet spot with:
/**
* Called by default implementation of {...@link #getHM}
* to lazily instantiate the HM for this widget.
*/
protected HM createHM();
/**
* All access to the widget's HM must be made through this method.
* It is an error to cache the object returned. The default
implementation
* returns the result of {...@link #createHM} the first time it is called.
*/
protected HM getHM();
If I override getHM(), I have the option to call the normal createHM() to
get whatever HM the widget normally uses. Or not. If I override
createHM() I
can provide a custom implementation, or wrap the normal one, without
having
to re-implement the lazy instantiation mechanism.
Am I trying to provide flexibility that no one is asking for?

[gwt-contrib] Re: RFC: sharded linking
Where can I read a description of what -XshardPrecompile, or see the code for it, it sounds very useful to me personally? It's not in 2.0.0 as far as I can see. My concerns about the sharded linking proposal came from what I understood the original flow to be from my looking at it and from the original sharded linkin proposal. current Precompile: - parse Java and run generators - output: number of permutations, AST, generated artifacts current CompilePerms: - input: permutation id, AST - compile one permutation to JavaScript - output: JavaScript, generated artifacts current Link: - input: JavaScript from all permutations, generated artifacts - run linkers on all artifacts - emit EmittedArtifacts into the final output If this isn't what the the current flow is then what is the current flow and how does sharded linking fit into that? On Feb 11, 6:43 pm, Scott Blum sco...@google.com wrote: I have a few comments, but first I wanted to raise the point that I'm not sure why we're having this argument about maximally sharded Precompiles at all. For one thing, it's already implemented, and optional, via -XshardPrecompile. I can't think of any reason to muck with this, or why it would have any relevance to sharded linking. Can we just table that part for now, or is there something I'm missing? Okay, so now on to sharded linking itself. Here's what I love: - Love the overall goals: do more work in parallel and eliminate serialization overhead. - Love the idea of simulated sharding because it enforces consistency. - Love that the linkers all run in the same order. Here's what I don't love: - I'm not sure why development mode wouldn't run a sharded link first. Wouldn't it make sense if development mode works just like production compile, it just runs a single development mode permutation shard link before running the final link? - I dislike the whole transition period followed by having to forcibly update all linkers, unless there's a really compelling reason to do so. Maybe I'm missing some use cases, but I don't see what problems result from having some linkers run early and others run late. As Lex noted, all the linkers are largely independent of each other and mostly won't step on each other's toes. - It seems unnecessary to have to annotate Artifacts to say which ones are transferable, because I thought we already mandated that all Artifacts have to be transferable. I have in mind a different proposal that I believe addresses the same goals, but in a less-disruptive fashion. Please feel free to poke holes in it: 1) Linker was made an abstract class specifically so that it could be extended later. I propose simply adding a new method linkSharded() with the same semantics as link(). Linkers that don't override this method would simply do nothing on the shards and possibly lose out on the opportunity to shard work. Linkers that can effectively do some work on shards would override this method to do so. (We might also have a relinkSharded() for development mode.) 2) Instead of trying to do automatic thinning, we just let the linkers themselves do the thinning. For example, one of the most serialization-expensive things we do is serialize/deserialze symbolMaps. To avoid this, we update SymbolMapsLinker to do most of its work during sharding, and update IFrameLinker (et al) to remove the CompilationResult during the sharded link so it never gets sent across to the final link. The pros to this idea are (I think) that you don't break anyone... instead you opt-in to the optimization. If you don't do anything, it should still work, but maybe slower than it could. The cons are... well maybe it's too simplistic and I'm missing some of the corner cases, or ways this could break down. Thoughts?

Cells are typed based on the type of data that the cell represents, and
they must implement a {{{render}}} method that renders the typed value as

act as a flyweight that handles events that are fired on elements that were

[gwt-contrib] conditional linkers and the primary.linker property
Reviewers: robertvawter, Description: This patch adds a way that deferred bindings can be differ depending on the choice of primary linker. This general functionality is necessary to get runAsync working for the cross-site linker, because doing so requires compiler rewrites that do not apply to the standard linker. After discussing the problem with Bob, a good-looking strategy is to have the add-linker tag take conditions as an argument. For example, it could look like this: add-linker name=xs when-property-is name=primary.linker value=xs / /add-linker This tag adds the xs linker if and only if the primary.linker is set for all permutations. To help users understand how this works, if they try to enable a linker for some but not all permutations, an error message is emitted. An example error message is as follows: Linker 'xs' is enabled for some permutations but not all of them In addition to allawing linkers to be added conditionally, the recommended way to set a primary linker will change. Currently, users do this: !-- DEPRECATED -- add-linker name=xs / The new style is like this: set-property name=primary.linker value=xs / The old style will still work for any application it already works for, but will be deprecated. An example deprecation message is as follows: [WARN] Linker 'test1' is primary but was not added via primary.linker Instead of add-linker, use: set-property name='primary.linker' value='test1' / If that doesn't work, contact the linker's maintainer IMPLEMENTATION ModuleDef used to have a list of linker classes that build up as the module is parsed. Now, it has a list of conditional linkers. Once parsing is complete, ModuleDef.finalizeLinkers should be called, which makes the final choice of which linkers are enabled.

As a use case, I'm working on a PRE linker that (currently) removes CompilationResults, alters them based on information collected from across all permutations, and then emits new ones. Obviously this isn't ideal--its expensive and CompilationResults were written to be (mostly) immutable--but it's also perfectly acceptable within the current design of the artifactSet/linker chain. The primary linker only cares about the set of compilation results it receives, and if an earlier linker altered them, it need never know. Hey, Brendan, it sounds like you are already pressing the limits of what is doable with linkers.Can you describe in more detail what this linker accomplishes? For this linker to be used in distributed builds, I believe you'd really want to come up with a way to do the JS rewrites on the sharded part. Otherwise, the final link node is going to have to do the JS rewrites for the whole build sequentially. What exact information is used as input to the rewrites? It seems (and I could definitely be misinterpreting here) that in both the simulated sharding procedure and Scott's alternate proposal, there will be sections of primary and post linkers running before a non- shardable pre linker. If that's true, then neither will be able to fully honor the ordering of linkers when shardable and non-shardable linkers are mixed. That's a large part of why I suggested that we phase out non-sharded linkers. In mixed mode, there isn't a perfect ordering to choose. With all sharded linkers, the order is simple and predictable. All sharded parts run before all final parts, and within either of those groups, PRE/PRIMARY/POST are respected. Continuing to think out loud, it seems that the way to alter my linker is probably either to statically derive what all permutations will need in every shard (as opposed to just having each triggered generator emit an artifact and collecting them at the end), or keeping that the same and creating a custom primary linker, which I was hoping not to do as it would tend to limit adoption. It might help to know that both generators and linkers have access to the full set of *possible* values of a deferred binding, not just the values for the current permutation. As an example, the LocaleListLinker reads off all possible values of locale and generates a file containing them: http://code.google.com/p/google-web-toolkit-incubator/source/browse/trunk/src/com/google/gwt/libideas/linker/LocaleListLinker.java Lex -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
Re: [gwt-contrib] RFC: sharded linking
On Thu, Feb 11, 2010 at 7:43 PM, Scott Blum sco...@google.com wrote: I have a few comments, but first I wanted to raise the point that I'm not sure why we're having this argument about maximally sharded Precompiles at all. For one thing, it's already implemented, and optional, via -XshardPrecompile. I can't think of any reason to muck with this, or why it would have any relevance to sharded linking. Can we just table that part for now, or is there something I'm missing? There are still two modes, but there's no more need for an explicit argument. For Compiler, precompile is never sharded. For the three-stage entry points, full sharding happens iff all linkers are shardable. - I'm not sure why development mode wouldn't run a sharded link first. Wouldn't it make sense if development mode works just like production compile, it just runs a single development mode permutation shard link before running the final link? Sure, we can do that. Note, though, that they will be running against an empty ArtifactSet, because there aren't any compiles for them to look at. Thus, they won't typically do anything. 2) Instead of trying to do automatic thinning, we just let the linkers themselves do the thinning. For example, one of the most serialization-expensive things we do is serialize/deserialze symbolMaps. To avoid this, we update SymbolMapsLinker to do most of its work during sharding, and update IFrameLinker (et al) to remove the CompilationResult during the sharded link so it never gets sent across to the final link. In addition to the other issues pointed out, note that this adds ordering constraints among the linkers. Any linker that deletes something must run after every linker that wants to look at it. Your example wouldn't work as is, because it would mean no POST linker can look at CompilationResults. It also wouldn't work to put the deletion in a POST linker, for the same reason. We'd have to work out a way for the deletions to happen last, after all the normal linkage activity. Suppose, continuing that idea, we add a POSTPOST order that is used only for deletion. If it's really only for deletion, then the usual link() API is overly general, because it lets linkers both add and remove artifacts during POSTPOST, which is not desired. So, we want a POSTPOST API that is only for deletion. Linkers somehow or another mark artifacts for deletion, but not anything else. At this point, though, isn't it pretty much the same as the automated thinning in the initial proposal? The pros to this idea are (I think) that you don't break anyone... instead you opt-in to the optimization. If you don't do anything, it should still work, but maybe slower than it could. The proposal that started this thread also does not break anyone. Lex -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
