Thanks @tuxcanfly. I'll go through and review this as time permits. It's obviously a huge change. |

Please add a TODO here to load the number of accounts from the db first and create the slice with enough space for them all at once. Otherwise, it's hard on the GC because it has to grow the backing array multiple times.
Also, super nit picky, but every other function has the bucket := ... line as the first one in the function, so I'd prefer that be consistent.

I'm now using a 'meta' bucket to store metadata like no of accounts, no of addrs etc and using it to create sized slices.
Moved bucket := ... to the first line.

I'm still reviewing, but one thing in general I want to bring up that we should discuss is how to avoid loading all of the addresses into a slice at once. That will not scale to millions/billions of addresses. |

I know that Go doesn't really care where the functions are placed, but the rest of code base strives to define functions before they are used. Please move this before NewAccount which is the first (and only) thing that uses it.

This should be exported since it's used in the Confg struct. It'll need a comment too once exported.

I think that the account names should not be set in the RPC handlers for gettransaction and listtransactions. These fields are deprecated in recent bitcoind wallet versions (which makes sense, since account balances there can change without an on-chain transaction) and we have plans for a proper ledger RPC to report credits and debits across accounts that is intentionally incompatible with bitcoind. |

@jrick Agreed, that would simplify some hoops I had to jump through to make the RPC results compat with core. |

This is not safe. The field is optional and this may be nil.

@jrick Thanks, updated. |
|
Alright, this looks good to go! Please squash it down to a single commit and rebase to the latest master. |
|
Done. |
NOTE: This pull request requires #147
Updated
waddrmgrto support account names and integrated with wallet RPC calls.
