Subject: [Kss-devel] ree-demoload branch merged to kss.demo/trunk
Message-ID: <pan.2007.09.30.22.00.29@ree.hu>


I merged the ree-demoload branch to kss.demo trunk.

kss.demo issues
---------------

As a result all actual demos are moved to the "demo" subdirectory. This 
directory is now placeless, so after a little testing we can just move it 
over to the core plugin under kss.core/plugins/core . After that kss.demo 
does not need to be touched any more if we make a new plugin or change 
the demo of an existing one.

The point is that all the plugins should have their demos as part of the 
plugin. The kss.template package provides a plugin skeleton that can be 
used with paster. You need to use the kss_zope_plugin template. The 
generated plugin comes with a simple but functional (!) demo page, and it 
immediately appears and becomes testable in the demo index page, if you 
include the zcml of the new plugin. So it'"s a great starting point if 
someone creates a new plugin.

Selenium tests are also supported by the new mechanism. However the 
createpythontests.py script cannot be used as before, instead the 
@@kss_demo_registry_admin/createSeleniumTests view needs to be called, 
and it generates out the seltest_all.py file exactly as the script did it 
previously previously (the result is placed under the selenium_utils 
directory). A new test only needs to be dropped as .html into the plugin 
demo's selenium_tests directory, to be included in the tests. 

I mainly wrote the abowe paragraph because the kissbot will need to be 
changed to call the view on the zope instance instead of the script, and 
use the results from selenium_utils directory. (Godefroid will make this 
as we agreed.) Other then this it will not be important for developers, 
the kissbot will do everything.

At a later point the original createpythontests.py will return to work 
again. This will happen when we switch to kss base and all the kss 
registry will move to plain pythonland. At this time, plugins will need 
to be touched a little (to move the kss registry to plain python) but the 
structure and logic will remain similar.


Zope3 issues
-------------

In addition to the above changes, I also made some fixes in kss.core and 
as a result now both kss.core and kss.demo trunk *works fully* on Zope3 
as well.

Only known issue is: zope unittests have never been made working on 
zope3. So part of the tests are failing with import errors. We still need 
to do this once.


Further actions
---------------

If everything is tested to work fine, I will:

- also backport kss.demo changes to 1.2 branch. There is no big risk 
since kss.demo is not part of any running application, but it will allow 
the paster template to be used immediately under Plone 3.0.

- move the actual demos and selenium tests to kss.core, under the core 
plugin where they really belong to. Further restructuring will be 
possible after that. (This will only happen on trunk, I won't touch 
kss.core 1.2 branch.)

- the zope3 fixes should go to kss.core 1.2 branch as well.

Subject: [Kss-devel] Weird behaviour with kssSubmitForm and empty selects
Message-ID: <fe17a2$pm8$1@sea.gmane.org>

Hi,

I have this TAL in oi.plum:

<select size="1" name="stream" id="addDeliverableStream">
                         <option
                             value=""
                             i18n:translate="stream_select_header"
                             style="font-weight: bold; border-bottom: 
solid black 1px;"
                             >Stream</option>

                         <option tal:repeat="stream view/streams"
                             tal:content="stream/title"
                             tal:attributes="value stream/cmf_uid;
                                             selected 
python:request.get('stream', None) == stream.cmf_uid() and 'selected' or 
None"
                             />
                     </select>

That first <option /> is a "label" (no space for an actual label) that 
submits an empty string. You're meant to pick something else in the list.

This works fine with the non-KSS form handler, which gets 
self.request.form['stream'] == "".

I then have this KSS:

#addDeliverableButton:click {
     evt-click-preventdefault: true;

     action-server: addNewDeliverable;
     addNewDeliverable-kssSubmitForm: currentForm();
}

In the addNewDeliverable action, I get self.request.form['stream'] == 
'Stream'. It works fine if I select a value, but when the value is "", 
it seems I get the select *label* and not the value.

I suspect there's some code like:

  if not value:
      value = label

but ... that's wrong. ;-)

Or no?

There is indeed some code in there which does this. I am guessing it is 
there for the case when there is no value specified on an option. This 
seems to have the unfortunate side effect you described. It would be 
nice to be able to detect an empty value. We will need to look into if 
this could made to work. There is a hasAttribute method on the DOM. 
Unfortunately IE 6 does not support this:

http://www.quirksmode.org/dom/w3c_core.html

Maybe there is some workaround for this in IE.

Subject: [Kss-devel] browser history
Message-ID: <ef1d3f8e0710160413x568b4ac8gf23af87d6ab3ca5@mail.gmail.com>

hi all,

during the sprint I worked on the browser history. I started the
integration of ReallySimpleHistory in kss as suggested by Jeroen.
I did a plugin as described in jeroen's presentation. then, for
testing purposes i did a mockup: on click event kss call my mockup and
it tells the client to add the anchor href url the the browser
history.

I needed also to modify the RSH library, I will talk about it in
another post later.

Actually I think that things start working, but I cannot test it
completely. I tried to add my
"self.getCommandSet('history').historify(url)" command at the end of
replaceContentRegion but it doesnt run as I expected.

even without my code, the @kssaction replaceContentRegion is not
called when I click on the "view"/"edit" tabs as I expect.
On every click it reloads the whole page..
is it the normal use case?

I tried also to figure out another case into add my command:
actions and workflow: it's better not to implement there.
inline editing: the same
calendar "<<" and ">>": it does not take the url as parameter, I may
change it, or rebuild it from the date..
the replaceContentRegion was the better solution in my opinion.
any hint?

more, jeroen told me to create an adapter that analyzes every url
request to plone and if it as a defined pattern in, it does some work,
otherwise it send it to plone as usually.
I'm not able to do that by myself. If someone could give me an empty
skeleton I would be very pleased :D

thanks, bye

Message-ID: <1192540537.12835.8.camel@gogolaptop>

Hi,
I started working on an open source live chat product for plone3.
There is a working prototype ready, however I would like to report the
following seeking for some advice...

1) While I can set a document:load on my kss there seems to be no
document:unload. That would be good to have for this use case as I would
like to know when a user leaves the chat room... Now I periodically try
to see if there was no user ping for a while to detect quitters, which
is not so nice...

2) I also use document:timeout to do the polling client-side. Is there a
way to set evt-timeout-delay at run-time rather than have it fixed? When
my product was using a custom js that I wrote, I used to set the ping
interval as a property of the chat room. Is is possible to set this
parameter somehow?

3) Doing a self.core.focus("#msgInput") seems to work fine on firefox
and the rest but not IE.

Thanks and keep up the good work...

Can you add a feature request/bug in the bug tracker of kssproject.org ?

You could store the value in HTML and access it as a KssAttr.

I thought this was working on IE. Can you file another bug and include 
IE version ?

There is one browser event (window.onbeforeunload) that could be 
implemented as document:unload (or, as a matter of fact, as 
document:beforeunload). This can even be done as a few lines plugin.

However there is no guarantee that it will be called. The client can just 
"go away". So you need to periodically check the presence of your clients 
anyway, in a chat application, or you may end up with clients stuck for 
infinity.

Subject: [Kss-devel] KSS in Plone 2.5 - replaceInnerHTML
Message-ID: <ffff2b$sgg$1@ger.gmane.org>

Hi all,

I'm trying to use KSS in Plone 2.5 (at least some basic functions of 
KSS). I'm using azax 1.1 and PloneAzax 1.1 branches. The major problem 
was, function replaceInnerHTML worked only if plaintext result was 
returned from action script (view class in my case). As soon as there 
was some HTML code, nothing happens on client side.

I was pretty sure this works some time ago (simple onclick event with 
replaceInnerHTML action), so I tried to use older version of kukit.js 
package. As I'v discovered, 
http://codespeak.net/svn/kukit/kukit.js/trunk in revision 46020 is 
working fine, but:
- revision 46026 displays error message on javascript console (Unhandled 
error during command execution: Bad payload, expected a text or a CDATA 
node)
- revision 46031 is the same
- .... there is a lot of "Replace string exceptions with proper ones" 
commits
- revision 46140 does not show the error message but silently "does not 
work" at all (spinner displays and hidesm but node contents is not 
replaced).

so I'm stuck on revision 46020.

Has anybody idea, if it is possible to fix replaceInnerHTML in kukit.js 
trunk to work properly in Plone 2.5 (Zope 2.9.8, Five 1.4.4, Firefox)?

Thanks in advance,

If you need kukit.js trunk, you'll have to fix PloneAzax as there has 
been some protocol changes.

Look at addHtmlParam in

http://codespeak.net/svn/kukit/kss.core/trunk/kss/core/commands.py

used by ''replaceInnerHTML'' in

http://codespeak.net/svn/kukit/kss.core/trunk/kss/core/plugins/core/commands.py

I'm not sure, whether I need kukit.js trunk or not. I'm using it, 
because trunk is mentioned in azax 1.1 EXTERNALS:

http://codespeak.net/svn/kukit/azax/branch/1.1/EXTERNALS.TXT

I suggest you don't spend time on fixing the azax/PloneAzax branches. 
Those branches are retired and will eventually be removed. They actually 
have been obsolate a year ago already, and no development was done on 
them since the azax -> kss namespace change.

We still currently run kss on a 2.5 branch in production, but it is 
heavily customized and we will migrate it asap.

If you really need kss on Plone 2.5 / Zope 2.9, it would be possible to 
backport kss.core 1.2 to Zope 2.9. We planned that originally, but there 
seems to be less and less interest in it, since Plone 3.0 is quite stable 
for production use.

May I ask why you are using the obsolete branch? To fix the branch you 
are using is hopeless and I strongly discourage you from doing so. To do 
the backport of 1.2 to Plone 2.5 would lead to a managable solution (just 
kss and no Plone support) but would be a lot of work for nothing. Why not 
simply upgrade your portal to 3.0? You would save an infinitely lot of 
time this way.

I'm using azax 1.1 because it seems as only one "working" solution for 
Plone 2.5/Zope 2.9. Your advice about upgrading to 3.0 is nice, but the 
project I'm trying to KSS-ize is pretty huge and in phase of customer 
acceptance. Customer wants "faster edits" and shortcuts and KSS is very 
good for it.

I don't want to spend a lot of time with migrating application few 
days/weeks before final acceptance. I need to close the mouth of my 
customer.

I know, "azax is dead", but I don't know any other, at least partialy 
working, solution for KSS in plone 2.5.

Thank you all for KSS,

I see. I understand your situation but you've been warned (you use 
unsupported code etc etc). However if you really want to use KSS on Plone 
2.5 on the long term, the solution would be to do the backport of version 
1.4.

In this case I suggest you try these branches:

http://codespeak.net/svn/kukit/azax/branch/1.1-ree-binding-improvements
https://svn.plone.org/svn/collective/plonekss/PloneAzax/branches/1.1

Again, no support but this "works on my machine", ie currently running on 
a live deployment.

Subject: [Kss-devel] How is the KSS context determined?
Message-ID: <ffm0nl$q7k$1@ger.gmane.org>

Hi guys,

How is the KSS context determined? That is, what is the base URL used 
when submitting a server-side request?

I think it's failing on namespace traversal adapters. I tried to use 
some KSS in a portlet, which is edited as e.g.

http://localhost:8080/test/++contextportlets++plone.rightcolumn/+/collective.portlet.tal.TALPortlet

KSS thinks the context here is the Plone site (/test), not 
/test/++contextportlets++plone.rightcolumn/+ (the adding view).

The same happens on edit:

http://localhost:8080/test/++contextportlets++plone.rightcolumn/Assignment/edit

This also gets the context as the site root, even though 
++contextportlets++plone.rightcolumn/Assignment is a persistent object.

Thi sis becoming a pretty big problem, as we're trying to make use of 
KSS in formlib widgets, which are used for things like portlets and 
content rules. :)

Subject: [Kss-devel] Escaping of replaceInnerHTML() output
Message-ID: <ffm58j$5iv$1@ger.gmane.org>

Hi guys,

I'm working on inline editing for content that uses formlib-based edit 
forms. It's actually working now in 
http://dev.plone.org/plone/browser/plone.app.form/branches/fschulze-optilude-usw

The approach is a bit different to the Archetypes version, though. One 
difference is that instead of calling a macro to render the output I get 
the raw output value as a string (from an IDisplayWidget) and then use 
replaceInnerHTML to place it into the correct node in the page.

However, I need to escape HTML properly. If you enter some HTML during 
inline editing, it shouldn't be rendered verbatim (as if it were 
inserted with structure:). This could potentially cause XSS type 
attacks, for example (even if it will be fixed once the page is reloaded 
and the normal view logic is used in this case). Only in some 
circumstances, such as for Text fields, should it come out that way.

Now, the IDisplayWidget actually takes care of this. I get a string such 
as '&lt;b&gt;Bold title&lt;/b&gt;' if I enter '<b>Bold title</b>' into 
the inline edit box. I then pass that to replaceInnerHTML() in the core 
command set.

Unfortunately, by the time this hits the DOM, it's been un-escaped. I 
can't exactly see how or where, but it seems that somethings translates 
those entities into proper characters again.

Digging around, I see that 
kss.core.plugins.core.commands.KssCoreCommands has this code:

def replaceInnerHTML(self, selector, new_value, withKssSetup='True'):
         new_value = HtmlParser(new_value)().encode('ascii', 
'xmlcharrefreplace')
         command = self.commands.addCommand('replaceInnerHTML', selector)
         data = command.addParam('html', new_value)
         data = command.addParam('withKssSetup', withKssSetup)

So, let's say the title I entered was "<b>Bold title</b>" as the input. 
The method is called with new_value = '&lt;b&gt;Bold title&lt;/b&gt;'. 
The first line of that function turns it into '&#60;b&#62;Bold 
title&#60;/b&#62;'.

In kss.core.parsesr.HtmlParser, we have:

     def __call__(self):
         value = unicode(self.soup)
         # Replace named HTML entitied in each case.
         # This is necessary for two reasons:
         # 1. Fixes an IE bug.
         # 2. Needed for the alternate transport mechanism to work.
         value = replace_html_named_entities(value)

         return value

Funnily enough, the last line turns this into u'&#60;b&#62;Bold 
title&#60;/b&#62;'. I don't know what the signifiance of the the two 
comments are.

This is the relevant part of the KSS reponse sent to the client:

<kukit:command selector="title-display"
                name="replaceInnerHTML" selectorType="htmlid">

     <kukit:param name="html">&#60;b&#62;Bold 
title&#60;/b&#62;</kukit:param>

     <kukit:param name="withKssSetup">True</kukit:param>

</kukit:command>

At this point, I'm not quite sure what happens. The plugin code looks 
like this:

kukit.actionsGlobalRegistry.register('replaceInnerHTML', function(oper) {
/*
*  accepts both string and dom.
*/
;;; oper.componentName = '[replaceInnerHTML] action';
     oper.evaluateParameters(['html'], {'withKssSetup': true});
     oper.evalBool('withKssSetup');
     var node = oper.node;
     var insertedNodes;
     if (typeof(oper.parms.html) == 'string') {
         node.innerHTML = oper.parms.html;
         insertedNodes = [];
         for (var i=0; i<node.childNodes.length; i++) {
             insertedNodes.push(node.childNodes[i]);
         }
     } else {
         oper.parms.html = kukit.dom.forceToDom(oper.parms.html);
         kukit.dom.clearChildNodes(node);
         insertedNodes = kukit.dom.appendChildren(
             oper.parms.html.childNodes, node);
     }
;;; kukit.logDebug(insertedNodes.length + ' nodes inserted.');
     if (oper.parms.withKssSetup) {
         kukit.engine.setupEvents(insertedNodes);
     }
});
kukit.commandsGlobalRegistry.registerFromAction('replaceInnerHTML',
     kukit.cr.makeSelectorCommand);

I assume there's something dodgy going on when you call node.innerHTML.

Is this a bug in KSS?

Before I go deeper into this I would like to ask something.

please try with version 1.4 (Plone trunk) as well and see if you have the

Between the two versions we changed the marshalling of html content. We 
were forced to do this by what we believed is a Firefox bug in handling 
namespaces / xpath queries. However we realized that actually the new way 
is the more correct way and besides it fixed some other problems as well 
it also made our code more simple and free from subtle xml/html issues. 
It may affect this issue, and if a fix is needed it should happen on the 
new version.

I switched to KSS trunk, and indeed it works now. Tags are properly 
escaped. I now need to test the opposite - having stuff *not* be escaped 
when explicitly requested, but I assume that'll work.

Will you backport this to the 1.2 branch? It seems like an important 
bugfix thing, with potential security implications.

*bump* - I'm happy to debug what goes on inside the namespace traversal 
adapters, but I need to know where to start looking. How does KSS know 
which base URL to submit to for an action-server?

The base url is decided in the file kukit.js, in the function 
kukit.Engine.prototype.calculateBase . It is pretty complicated, and I 
actually have no remembering of neither a description of the supported 
use cases nor a written discussion about it.

As I read from the code it tries to fetch the base in the following order:

1. if there is a link with rel="kss-base-url", it is using the href of 
that as base. This allows a manual override from the template. I cannot 
tell you why/when this is needed or used, since point 2. is meant to do 
exactly the same.

2. if there is a "base" tag in the html, it is using its href. In 
addition it strips the trailing "/" from it, if there is one. This is 
what happens normally, I believe also in your case.

3. If this is not present it uses window.location from javascript.

I hope this helps something, please contact me when you want about this 
issue, I'd try to look at it deeper as well. We may need to improve this 
algorithm to cover the case you are using.

Best wishes

Let's say I have a piece of javascript that does something like

mybutton has an event attached to it thanks to my KSS rule:

button#someid:click {

I want the azax event handler to also fire, but it does not since events 
are not generated when doing a click through Javascript.

Question: how do I force that event to fire?

I've been through kukit.js and it seems that in one of the rules or 
rule_processors arrays lies the callable objects. Is this correct?

There is no way of firing a browser event manually. There will however be 
a way of firing all the actions bound by a given kss rule, on a given 
node (which ends up at the same result).

Currently the following methods can be used. They are both methods on an 
_event binder_ instance in javascript.

  binderinstance.__continueEvent__(eventname, node, defaultParameters)

This executes the actions bound on the binder instance, for the given 
eventname, on the given node.

  binderinstance.__continueEvent_allNodes__(eventname, defaultParameters)

This executes the actions bound on the binder instance, for the given 
eventname, on all the nodes bound in this instance.

These were made to cover use cases for continuation events. There are 
examples in kss.demo for this as well as in the upcoming 
kss.plugin.livesearch plugin. There are also some comments to explain the 
call signature of these methods in the eventreg.js file.

There is currently no commodity method for calling up all the events on 
all the necessary binder instances (or on the singleton binder instance 
as in case of click), on a given node - this is what you would like to 
have. We will take care of providing a clean API for this task in the 
next version of kss.

I cannot go into deeper explanation here about what an event binder 
instance is or how you would look it up from the registry. I will, 
however, try to write a small recipee page on kssproject.org about this, 
which will enable you to use this even before the cleaner API arrives. No 
deadline promised though.:(

Best wishes,
