de9a1db Acquire cs_main lock before cs_wallet during wallet initialization (Russell Yanofsky) Pull request description: `CWallet::MarkConflicted` may acquire the `cs_main` lock after `CWalletDB::LoadWallet` acquires the `cs_wallet` lock during wallet initialization. (`CWalletDB::LoadWallet` calls `ReadKeyValue` which calls `CWallet::LoadToWallet` which calls `CWallet::MarkConflicted`). This is the opposite order that `cs_main` and `cs_wallet` locks are acquired in the rest of the code, and so leads to `POTENTIAL DEADLOCK DETECTED` errors if bitcoin is built with `-DDEBUG_LOCKORDER`. This commit changes `CWallet::LoadWallet` (which calls `CWalletDB::LoadWallet`) to acquire both locks in the standard order.

(Alex Morcos) a54c7b9 Fix rounding errors in calculation of minimum change size (Alex Morcos) Pull request description: Thanks to @juscamarena for reporting this. Please backport to 0.15. There was a potential rounding error where the fee for the change added to the fee for the original tx could be less than the fee for the tx including change. This is fixed in the first commit. The second commit adds one more snippet of information in the fee calculation report. I actually realized that there is more information that would be nice to report, but we can add that post 0.15. An open question is whether we should be returning failure if the test in line 2885 is hit or just resetting pick_new_inputs and continuing. Originally I made it a failure to avoid any possible infinite loops. But the case hit here is an example of where that logic possibly backfired.

This change is desirable because wallet.h/cpp are monolithic and hard to navigate, so pulling things out and grouping together pieces of related functionality should improve the organization. Another motivation is the wallet process separation work in https://github.com/bitcoin/bitcoin/pull/10973, where (at least initially) parameter parsing and fee estimation are still done in the main process rather than the wallet process, and having functions that run in different processes scrambled up throughout wallet.cpp is unnecessarily confusing.

e53615b Remove vchDefaultKey and have better first run detection (Andrew Chow) Pull request description: Removes vchDefaultKey which was only used for first run detection. Improves wallet first run detection by checking to see if any keys were read from the database. This also fixes a (rather contrived) case where an encrypted non-HD wallet has corruption such that the default key is no longer valid and is loaded into a Core version that supports HD wallets. This causes a runtime exception since a new hd master key is generated as the software believes the wallet file is newly created but cannot add the generated key to the wallet since it is encrypted. I was only able to replicate this error by creating a non-hd wallet, encrypting it, then editing the wallet using `db_dump` and `db_load` before loading the wallet with hd enabled. This problem has been reported by [two](https://bitcointalk.org/index.php?topic=1993244.0) [users](https://bitcointalk.org/index.php?topic=1746976.msg17511261#msg17511261) so it is something that can happen, although that raises the question of "what corrupted the default key". ~P.S.

Dust is redefined to be the value of an output such that it would cost that value in fees to (create and) spend the output at the dust relay rate. The previous definition was that it would cost 1/3 of the value. The default dust relay rate is correspondingly increased to 3000 sat/kB so the actual default dust output value of 546 satoshis for a non-segwit output remains unchanged. This commit is a refactor only unless a dustrelayfee is passed on the commandline in which case that number now needs to be increased by a factor of 3 to get the same behavior. -dustrelayfee is a hidden command line option. Note: It's not exactly a refactor due to edge case changes in rounding as evidenced by the required change to the unit test. A discard_rate is added which defaults to 10,000 sat/kB Any change output which would be dust at the discard_rate you are willing to discard completely and add to fee (as well as continuing to pay the fee that would have been needed for creating the change) This would be a nice addition for 0.15 and I think will remain useful for 0.16 with the new coin selection algorithms in discussion, but its not crucial.

2017-07-18Do not allow users to get keys from keypool without reserving themMatt Corallo
fundrawtransaction allows users to add a change output and then not have it removed from keypool. While it would be nice to have users follow the normal CreateTransaction/CommitTransaction process we use internally, there isnt much benefit in exposing this option, especially with HD wallets, while there is ample room for users to misunderstand or misuse this option. This could be particularly nasty in some use-cases (especially pre-HD-split) - eg a user might fundrawtransaction, then call getnewaddress, hand out the address for someone to pay them, then sendrawtransaction. This may result in the user thinking they have received payment, even though it was really just their own change! This could obviously result in needless key-reuse.

This fixes an issue where you could reserve a keypool entry, then top up the keypool, writing out a new key at the given index, then return they key from the pool. This isnt likely to cause issues, but given there is no reason to ever re-use keypool indexes (they're 64 bits...), best to avoid it alltogether.

This speeds up adding keys by well over 10x on my laptop (actually something like 17x), I wouldn't be surprised if it were an even bigger speedup on spinning rust. Then it increases the keypool size to 1000. I would have preferred to use 10,000 but in the case where the user creates a new wallet and then turns on encryption it seems kind of dumb to have >400KB of marked-used born unencrypted keys just laying around.
