New structure for storing the state history of CFundDB entries. Those are stored in a map associating blockhash and state, allowing to directly revert state transitions when reorganizations are seen.
verifychainnow checks for the consistency of the CFundDB state hash when level 4 is specified.
This set of changes will require older clients to reindex on launch, keeping the node offline for some hours at best. In order to reduce downtime, node operators can proceed as follows if needed:
Close node with old version.
mkdir /tmp/reindexdata; cp -rf <data_folder>/blocks /tmp/reindexdata/; cp -rf <data_folder>/chainstate /tmp/reindexdata/
Reopen node with old version. It will be again online
Launch in parallel a second instance of the node, this time using the new version with the parameters
Once the reindex finishes, close both nodes and copy back the reindexed data.
rm -rf <data_folder>/blocks <data_folder>/chainstate; cp -rf /tmp/reindexdata/* <data_folder>
Relaunch new version of the node.
CFundDB extra log and ensure read before modify
