Subject: Zero-length array fix impact

Hello,

 

I would like to confirm my understanding of this issue: the 7.0.5 release notes say that “Since these changes affect the Channel Access client-side API they will require rebuilding any CA Gateways against this version or Base to properly handle zero-length arrays.”.

I assume that the gateways would still work without rebuild, but handle the zero-length arrays in the old buggy way. Which is of course not a desirable situation (behavior depends if the access was over a gateway or not) but the gateway would not crash.

 

Is this correct? Eventually we of course need to rebuild the CA gateways (or drop them and use only p4p.gw), this just has some potential implications on our version update planning.

 

Cheers,

 

Timo
