wallet: No BDB creation, unless -deprecatedrpc=create_bdb #28597

   maflcko commented at 1:50 pm on October 5, 2023: member

   With BDB being removed soon, it seems confusing and harmful to allow users to create fresh BDB wallets going forward, as it would load them with an additional burden of having to migrate them soon after.

   Also, it would be good to allow for one release for test (and external) scripts to adapt.

   Fix all issues by introducing the -deprecatedrpc=create_bdb setting.

   Concept ACK.

   Maybe add a small test creating a legacy wallet without the “create_bdb” flag? asserting the error is being properly thrown.

   Yes, happy to push a commit or patch, if someone writes one. Otherwise, it should be possible to test locally:

   0$ ./src/bitcoin-cli -datadir=/tmp -regtest createwallet name false false "" false false
   1error code: -4
   2error message:
   3BDB wallet creation is deprecated and will be removed in a future release. In this release it can be re-enabled temporarily with the -deprecatedrpc=create_bdb setting.

    On a second thought, probably better to call it “create_legacy_wallet” instead of “create_bdb”. Users might not be aware of the legacy wallet db engine name.

    Users might not be aware of the legacy wallet db engine name.

    I think BDB is mentioned in all compile docs, as well as the GUI. Maybe not in the RPC interface, but it is explained in this pull.

    Though, happy to change.
