Code Review ACK f59959e
The reasoning for this change, as far as I understood this PR, is this:
- In the
GetWalletForJSONRPCRequestfunction, we only needed the wallet shared pointer if the number of context wallets equals one. In other cases, we would like to return an error. - So for this, we would not like this function to have information about all the wallets corresponding to context.
- That is why this PR suggests moving this process of unloading all wallets and returning a single one to a function in the wallet.cpp file.
I have checked that the changed code is clean and clear to reason with. And if my original understanding of this PR is correct, I think this PR can be merged. And in case my analysis was erroneous, please do correct me.

What do you mean by "unload" in this context? |
|
The actual wallet unload, which occurs on the last shared pointer. |
|
Oh, I see. Is there a scenario where this could actually happen, and if so, can we test for it? |
|
Could happen when an explicit unload races with other call of any wallet. I don't think we can test without code changes. |

ACK f59959e |
