Subject dealing with empty field names in query
Date Fri, 06 Feb 2009 18:27:02 GMT
Hi mod_perl list,

We're using more and more javascript to do clever things with forms, and 
I think we broke the Apache2::Request parser, but wanted to check before 
reporting it as a bug.  (and tell me if this should go to the apreq list)

With the following request body:

i1=drnk4&basket%3A_new_de9a792da0f5127d72d7c6a5f6b2d4c5%3Aquan
tity=1&basket%3A_new_de9a792da0f5127d72d7c6a5f6b2d4c5%3Aid=de9a792da0f5127d72d7c6a5f
6b2d4c5&i2=clth12&basket%3A_new_7acf9602cd6ab0ee86f77efeaaffefff%3Aquantity=1&basket
%3A_new_7acf9602cd6ab0ee86f77efeaaffefff%3Aid=7acf9602cd6ab0ee86f77efeaaffefff&i3=&=
&=&i4=&=&=&i5=&=&=&i6=&=&=&action=insert&x=46&y=17

When I create a new Apache2::Request object and loop through the 
parameters, I get this: (output from Data::Dumper of a hash of the params)

  'basket:_new_7acf9602cd6ab0ee86f77efeaaffefff:id' => 
'7acf9602cd6ab0ee86f77efeaaff
efff',
  'basket:_new_7acf9602cd6ab0ee86f77efeaaffefff:quantity' => '1',
  'basket:_new_de9a792da0f5127d72d7c6a5f6b2d4c5:id' => 
'de9a792da0f5127d72d7c6a5f6b2
d4c5',
  'basket:_new_de9a792da0f5127d72d7c6a5f6b2d4c5:quantity' => '1',
  'i1' => 'drnk4',
  'i2' => 'clth12',
  'i3' => ''

So it stops parsing when it gets an '=' straight after an ampersand.

I looked up the spec and it doesn't seem to explicitly say, so I don't 
think we should just stop parsing.

Spec:

thanks
John
