1. Test an Online Database Utility

I need some people to go to

   http://www.cklester.com/dbtest/

and play around with the site. Make some databases. Make some tables. Make
some records. Delete some or all of the above.

Also, how would one make a page so a user could upload a graphic?

Thanks!

Hey, rudy... thanks for testing it for me.

As you can see, for this test the input is pretty limited: one text item for
the key and one string of text for the data. I'll see about delimiting fields
in the next iteration. :)

Uploading a file with CGI came up once before.
Here's what I said then:

Yes, I didn't want you guys creating a billion databases/tables/records. :)

One interesting note: somebody created a database called *. When it was
deleted, all the databases got deleted (*.edb)... Clever! Glad I patched
that up quickly, although the slashes weren't getting converted from their
html equivalent (../ became ..%2N (or something)).

Anybody got code for receiving a file via upload? I'll check all of Rob's
web code. :)

Yeah, I intend to use fields next iteration...

Bernie, where is it required?

I just uploaded two CGI libraries to the archive (in one zip file)
that I've been using for years. I didn't realize they weren't in the
Archive any more. LibCGI has excellent support for multi-part forms
(which include file uploads).

And actually, as long as you don't use any of the 'RDS Incompatible' features,
(var_id, eval, goto) you can pre-process the code so that it will run with 
the standard RDS interpreter.

I'm in the process right now of adding constructors.  It's pretty simple.
You just create a member function with the same name as the class.  In fact,
as long as the parameters are different, you can create multiple constructors.
Here's a simple example from one of the demos (just a part of the full demo):

euclass ECircle( EShape c )
	-- This is a shape defined by its center and a radius.
	-- Note that the Center is an EPoint.
	EPoint Center
	atom Radius
	
	-- The constructor isn't very interesting, but it
	-- does initialize the sequence.
	function ECircle( EPoint center, atom radius )
		ECircle this
		this = repeat( 0, ECircle.Radius )
		this.Name = "Circle"
		this.Center = center
		this.Radius = radius
		return this
	end function
	
	-- This is an alternate form of creation, in case you'd rather
	-- supply two atoms rather than a sequence.
	function ECircle( atom x, atom y, atom radius )
		return ECircle( {x,y}, radius )
	end function
end euclass

ECircle c
c = ECircle( 0, 1, 1 )

I think it makes creating euclass type objects more intuitive, and the
modifications are fairly simple.

In fact, I could bug this site all night...
http://www.cklester.com/dbtest/?db=@.edb doesn't even work.  You need to check
invalid characters and character limits all of the way down the line.

After you do that, I'll try to break it again. ;)
