[Pharo-project] zinc incompatibilities with gemstone

[Esteban Lorenzano]

Hi,
I'm trying to load Zinc on gemstone. It more or less loads fine, but there are 
some fixes needed, I'm attaching the problems I found, hoping some benevolent 
soul will integrate to gemstone zinc code :)
 
This are the problems found: 
        
ZnUrl>>scheme: symbol
        symbol isNil 
                ifTrue: [ scheme := nil ]
                ifFalse: [ 
                        (#(#http #https) includes: symbol) "<== they need to be 
strings (symbols ~= strings in gemstone)"
                                ifTrue: [ scheme := symbol asSymbol ]
                                ifFalse: [ (ZnUnknowScheme scheme: symbol) 
signal ] ]
                                
                                
ZnNetworkingUtils>>isProxySet
        "Should a proxy be used ?"
        
        ^ NetworkSystemSettings useHTTPProxy "<== This class does not exists." 
        
ZnNetworkingUtils>>socketStreamTimeout
        "Access the current timeout in seconds for SocketStream IO"
        
        ^ ZnConnectionTimeout value "<== DynamicVariable class (parent of 
ZnConnectionTimeout) does not exists."

best,
Esteban
