See #6896 for the bug that this PR is addressing.
These changes intend to make BSim more friendly for querying binaries that have multiple overlay address spaces. It accomplishes this by adding the
spaceidfield to a number of objects that are used by BSim, such as theFunctionDescriptionandCallRecord. Thisspaceidfield represents the Address Space ID and it is used to retrieve the original Address Space of the function. By combining the Address Space with the longoffset(the address that is currently being stored) we now have all the information we need to reliably retrieve functions for comparison.Backwards Compatibility
I want to note that this solution creates an issue of backwards compatibility with existing BSim servers. This is because I added a new column to the
desctableto store the address space id with the functions offset. Querying a database that has not been created by the updated version of the client would cause errors as that column would be missing. I'm unsure of the best step forward to resolve this concern, but I would be interested in speaking about potential options like using theDatabaseInformationobject to check for compatibility.
