[Pharo-project] Zinc problems found

[Esteban Lorenzano]

Hi, 
I found some problems on Zinc implementation.

Take this example: 

HTTPSocket 
        httpGetDocument: 
'http://127.0.0.1:333/analytics/feeds/accounts/default' 
        args: (Dictionary new 
                at: 'prettyprint' put: #('true');
                yourself)
        accept: '*/*' 
        request: ('Authorization: GoogleLogin Auth={1}{2}' format: {self 
authenticationKey. String crlf}

this, if I have the correct authentication key, gives me the correct answer (an 
atom-xml response). 

Now, if I try: 

ZnHTTPSocketFacade
        httpGetDocument: 
'http://127.0.0.1:333/analytics/feeds/accounts/default' 
        args: (Dictionary new 
                at: 'prettyprint' put: #('true');
                yourself)
        accept: '*/*' 
        request: ('Authorization: GoogleLogin Auth={1}{2}' format: {self 
authenticationKey. String crlf}

(this should work, as the facade is for compatibility, I think)

I have two errors, one of them easily solvable, and the other... well... I 
couldn't solve it in the 15' I spent on it :)

1) arguments are not in the correct way. While HTTPSocket functions expect 
something like this: 

Dictionary new 
        at: 'prettyprint' put: #('true'); "<-- Parameter is an array"
        yourself.

ZnHTTPSocketFacade expects something like this: 

Dictionary new 
        at: 'prettyprint' put: 'true'; "<-- Parameter is a string"
        yourself.

2) This is the hard one. If you do the get request with parameter fixed, you 
should get the atom feed. 
But you don't. 
You get a  ZnResponse who is OK (status 200), but entity is empty. I followed 
the error until this method: 

canReadContent
        ^ self hasContentLength or: [ self isChunked or: [ self 
allowsReadingUpToEnd ] ]

who return false, because none of the questions is true. Then, no entity is 
filled, and I have no answer :(

Hope this help :)

Cheers,
Esteban
