[Webmacro-devel] New WM Package Structure

[Eric B. R. <eb...@tc...>]

I've modified the NextRelease page on the website include what we want 
our new package structure to be.  This is based on the (little bit of) 
discussion we've had here on this list.

If you have comments please add them to the page, or discuss them here.

[Webmacro-devel] Ignition progress

[Marc P. <ma...@an...>]

For those interested and sitting on the fence, I will periodically update:

http://www.webmacro.org/IgnitionApplication

With the current status of the app.

Once again... please download and try it out. It's not a pile of crap, I 
promise. It's not "alpha" quality really, it would be releasable now with a 
bit of testing and Transaction, Authentication and Validation support (in 
progress).

Sorry to go on about it... to download:

http://www.wangjammers.org/ignition

To see it running and read the (good) docs:

http://212.135.236.36:8080/ignition

[Webmacro-devel] Setting up SF tracker

[Marc P. <ma...@an...>]

Guys,

We have default SF trackers set up for:

* Bugs
* Support Requests
* Patches
* Feature Requests

We can create more if required (i.e. Ignition bugs / RFE etc. hint hint!).

I need to set up our "categories". For the "Bugs" tracker I'm thinking:

* Parser
* Template loading
* Caching
* Distribution
* Configuration
* Servlet Container Compatibility
* i18n

Anybody think of any more? You can't delete categories once added, so I 
need to be sure you're all happy with my choices.

I'm just nominating myself to do this as nobody else is doing it.

Marc

[Webmacro-devel] Wiki edits I've done

[Marc P. <ma...@an...>]

A couple of minor things:

1. http://www.webmacro.org/QuickStart - I have made it link to 
WebMacroScriptTrail instead of AllDirectives
2. http://www.webmacro.org/NoServlet - I have fixed the link to CVS 
/examples, to go to SF, and added some wording. In future I will add 
example code to this page showing the easiest way to load and render a 
template to System.out.

I'm afraid it's not that simple. In this kind of scenario you need to 
generate unique field names based on your data / field number i.e. <input 
name="field3_submit">.

Then your servlet parses all the request parameters to see which one has a 
value.

That's one way of doing it anyway.

Best wishes,
Marc

Solution: Put your templates in a .JAR file and sign the templates. Make 
your code check the signature of the templates at startup (because they are 
in a jar, they can't be modified while the code is running) and if the 
files have been modified, don't execute.

That's a serious complication compared to the existing code! You've got 
source-code generation or byte code generation to do in there.

I'm pretty sure this is beyond the scope of WM.

You will very quickly notice that this is a problem, because people will 
get StackOverflowError showing in the error response they get. If your 
admin doesn't fix it after users tell him that, then you should fire him!

Performance and more importantly don't want to deploy source tempates on
production server. There is no need to reload and don't want a someone/me to
open file and make a mistake.

["Harmeet Bedi" <ha...@ko...>]
No I haven't and looking at the source code it appears that WM developers
have spent good time on tuning.  Also WM seems very responsive.
It is more based on the gut feel that you are using Java interpreter and WM
interpretter on top of it, if you remove one layer the system becomes easier
to understand and profile. This is esp. important if one does not care about
reloading templates.

["Harmeet Bedi" <ha...@ko...>]
As a general rule, yes I agree templates don't need compilation and it robs
them of power, but as a user in one case I don't want the templates to be
modifiable. Structure to support dynamic reloading of templates is
unnecessary. A jar file with classes may be more comfortable than deploying
source templates. These classes could be generated from wm templates.
I am not sure why it would complicate things. I was thinking it would be a
translation into java objects from wm template and writing the restulting
structure on disk rather than executing when user hits a template.

["Harmeet Bedi" <ha...@ko...>]
True but WM could say a thread local variable which monitors start time of
interaction and check for threashold at different points and if the
execution time is more than allowed throw a runtime exception.

["Harmeet Bedi" <ha...@ko...>]
Thanks for the tip, will look into Ignition.
The one problem with wrapping a unsafe object is that often it is hard to
figure out what is safe and not. So it would be nice if WM folks could
provide a set of object wrapper with degrees of safety. So for instance
NoviceReadonlySafeHttpServletRequest for some templates and maybe a more
advanced
AdvancedRedirectAndContextAllowedSafeHttpServeletRequest
for a more power user.
I realize though that this is slippery slope and users may want different
things, but I also think some common safe objects could help a lot.

["Harmeet Bedi" <ha...@ko...>]
Sorry I ment that it shold not cause stack overflow. It has a bad impact on
CPU and can cause other requests to be less responsive. Assuming (a) model
and context varialbes exposed to templates is well thought out and safe, and
(b) anyone is allowed to add their templates, it would be really nice if
there can a way to prevent stack overflow condition. It would be harder to
debug these conditions for a end user and would have less than nice impact
on server, so would be nice to have way to prevent it.

[Webmacro-devel] How to get info from HTML

[gang w. <gan...@ho...>]

Hi,

I have a question on passing parameter from HTML to servlet. The situation 
is:

1. I can pass a ArrayList from servlet to HTML which is called company_list.

2. When HTML displayed it dynamically created a table with several buttons 
in it:

<table>
#foreach $entry in $company_list
{
<tr>
	<td>$entry.field1</td>
	<td>$entry.field2</td>
	<td>$entry.field3</td>
	<td><input type=submit name="???" value=Select></td>
</tr>
}
</table>

3. What I want to do next is: click any one of those buttons to invoke next 
HTML page. In between servlet need to know which button was clicked and get 
the information (field1 for example).

Could someone show me a few lines of servlet code on how to do it?

Thank you in advance.

Gang Wu

Hmm very strange. You can edit WEB-INF/classes/VLHDefaults.properties to 
set a Windoze-friendly location and see if it helps. No docs on that yet, 
waiting for Lane to pull that rabbit out of the hat.

Ah thanks. No problem I'll fix that, easy to do. It's on the todo list now.

Hmmm.  Strangely after a couple of restarts it is working again.  The filese
apparently existed all along, as they are dated from Friday.  Perhaps this
is a Windoze drive letter thing, like if I start the server from a different
drive it can't find the files?  I'll try to experiement.

Another little bug is with the anchor tags in the documentation.  I think
they need to be URL encoded.  For example:

<a name="sec_Example 2. A cleaner "Hello, World!"">

This obviously won't work because of the double quotes.  I'm not sure about
the blanks and other special characters, but $URLEncode($link) should fix
the problem.

This is (passing buck) Lane's code :-)

It's the filesystem-based VLH. It sounds like you did have the files (or it 
would never have worked) and you have deleted them while Ignition is 
running. They are auto-generated if they do not exist, but I suspect only 
at startup.

So, if you deleted/moved a directory (or your mounts/drive names changed) 
called /deploy then that would explain it.

Try restarting your servlet container.

Let me know how it goes. If you need any more help you can reach me on 
Yahoo as marcp_uk, AIM as HateAiOiL or ICQ 2930802.

No way, our mails are very uninformative to the outsider!

I have added some text to it:

"   <table>
     <!-- #foreach $User in $Users -->
     <tr><td>$User.Name</td><td>$User.Address</td></tr>
     <!-- #end -->
   </table>

This would render as a table, whereas without the comments it might not. 
The above workaround works in a way that may not be immediately obvious. 
Empty HTML comments are left in the output for each row (--> and <!--) and 
the outer comment open/close finish it all off so it is legal HTML."

[Marc P. <ma...@an...>]

Hi all,

I know that I released Ignition on the worst day possible, a Friday. Now 
you're all in work and really busy with Monday morning stuff.

However I would really like as many WM developers as possible to check out 
Ignition (http://www.wangjammers.org/ignition) and share their thoughts on 
it here.

Feedback is really appreciated, particularly on whether or not this should 
become part of the "WM project" as the "public face" of the WM library 
code, something people can use straight away with great effect.

Today I'm implementing a simple automatic transaction mechanism and doing 
some major refactoring to rationalise the configuration implementation and 
main servlet a lot.

Best wishes,
Marc

  good point. I have felt there was some headroom for getting a context

Haha yes you're right. Looks like it would. I don't know who wrote that.

Do anyone understand that comment about code within HTML comments? And

around??

By this I mean without requiring even an implicit FastWriter etc.

I have to say I agree with this sentiment. All the Broker and related 
baggage we carry is the only major criticism Velocity fanciers can still 
level at us.

I don't think we should get rid of it all, at all. We should just make our 
"baggage" optional, and use defaults implementations where possible. I know 
we do this in most places.

However, we simply -must-be able to do something like this:

    WebMacro wm = new WM();
    Context ctx = wm.getContext();
    Template t = new FileTemplate( myTemplate);
    ctx.put( "myVar", "myValue");
    wm.evaluate(t, ctx, System.out);

If we can't do something as simple as that, the WM barrier (to entry) is 
way too high.

Throw away FastWriter. Throw away the very strange buffering of the entire
page before output to the user. Throw away all those "performance hacks",
yes yes, and keep the -template engine-.

I'd like to have a template engine. One that takes a Template, a Context
and then renders the combined information to a stream. Could WM provide me
with that, without lots of stash, Threads, strange configs, weird search
