f4d00e6 Add a discard_rate (Alex Morcos)
b138585 Remove factor of 3 from definition of dust. (Alex Morcos)
Pull request description:
The definition of dust is redefined to remove the factor of 3.
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.
It does add translation strings, but we could (should?) avoid that by hiding the option

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.

Pull request description:
This carries the walletdb object from top-up through GenerateNewKey/DeriveNewChildKey/CWallet::AddKeyPubKey, which allows us to avoid the flush on destruction until the top up finishes instead of flushing the wallet for every key.
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.

Pull request description:
This builds on #10589 (first 5 commits from that PR, last 5 commits are new)
The first couple commits refactor to use the CCoinControl class to pass fee calculation parameters around.
This allows for fixing the buggy interaction in QT between the global payTxFee which can be modified by the RPC call settxfee or temporarily modified by the QT custom fee settings. Before these changes the GUI could sometimes send a transaction with a recently set payTxFee and not respect the settings displayed in the GUI. After these changes, using the GUI does not involve the global transaction confirm target or payTxFee.
The prospective fee displays in the smart fee slider and the coin control dialog are changed to use the fee calculation from GetMinimumFee, this simplifies the code and makes them slightly more correct in edge cases.
Maxing the fee calculation with the mempool min fee is move from estimateSmartFee to GetMinimumFee.
This fixes a long standing bug, and should be tagged for 0.15 as it is holding up finalizing the estimatesmartfee RPC API before release.

Remove helper function (CalculateEstimateType) for determining whether
estimates should be conservative or not, now that this is only called
once from GetMinimumFee and incorporate the logic directly there.
GetMinimumFee now passes the conservative argument into estimateSmartFee.
Call CalculateEstimateType(mode) before calling GetMinimumFee or estimateSmartFee to determine the value of this argument.
CCoinControl can now be used to control this mode.

It also gets rid of the circuitous `ScriptForMining` method on

No change in behavior. Get rid of specifiedConfirmTarget if/else block and
rename specifiedConfirmTarget and ignoreUserSetFee variables to
ignoreGlobalPayTxFee.
Motivation for moving these is to make supporting IPC simpler (#10102), so
these lookups can be one-shot IPC requests, instead of back-and-forth
interactions over the IPC channel.
Also these functions are potentially useful outside of the bitcoin GUI (e.g.
for RPCs).

Instead, CWalletDB() with a dummy handle will just give you a no-op
database in which writes always succeeds and reads always fail. CDB
already had functionality for this, so just use that.
Abstract database handle from explicit strFilename into
CWalletDBWrapper.
Also move CWallet::Backup to db.cpp - as it deals with representation
details this is a database specific operation.
608bbcc [qt] Stop treating coinbase outputs differently: show them at 1conf (Matt Corallo)

This makes SetHDMasterKey responsible for maintinaing the CHDChain
version instead of always creating it with the latest version and
making EncryptWallet responsible for keeping the version from
changing.
This removes another callback from block connection logic, making it
easier to reason about the wallet-RPCs-returns-stale-info issue.
UpdatedTransaction was previously used by the GUI to display
coinbase transactions only after they have a block built on top of
them. This worked fine for in most cases, but only worked due to a
corner case if the user received a coinbase payout in a block
immediately prior to restart. In that case, the normal process of
caching the most recent coinbase transaction's hash would not work,
and instead it would only work because of the on-load -checkblocks
calling DisconnectBlock and ConnectBlock on the current tip.
In order to make this more robust, a full mapWallet loop after the
first block which is connected after restart was added.

This simplifies fixing the wallet-returns-stale-info issue as we
can now hold cs_wallet across an entire block instead of only
per-tx (though we only actually do so in the next commit).
This change also removes the NOT_IN_BLOCK constant in favor of only
passing the CBlockIndex* parameter to SyncTransactions when a new
block is being connected, instead of also when a block is being
disconnected.
This change adds a parameter to BlockConnectedDisconnected which
lists the transactions which were removed from mempool due to
confliction as a result of this operation. While its somewhat of a
shame to make block-validation-logic generate a list of mempool
changes to be included in its generated callbacks, fixing this isnt
too hard.
Further in this change-set, CValidationInterface starts listening
to mempool directly, placing it in the middle and giving it a bit
of logic to know how to route notifications from block-validation,
mempool, etc (though not listening for conflicted-removals yet).
This removes the option from the wallet to not pay a fee on "small"
transactions which spend "old" inputs.
This code is no longer worth keeping around, as almost all miners
prefer not to include transactions which pay no fee at all.
Because it is used inconsistently at least version 5.4.0 of g++ to
complains about methods that don't use override. There is two ways to go
about this: remove override from the methods having it, or add it to the
methods missing it. I chose the second.
When importing a watch-only address over importmulti with a specific timestamp,
the wallet's nTimeFirstKey is currently set to 1. After this change, the
provided timestamp will be used and stored as metadata associated with
watch-only key. This can improve wallet performance because it can avoid the
need to scan the entire blockchain for watch only addresses when timestamps are
provided.
Also adds timestamp to validateaddress return value (needed for tests).

This command allows a user to increase the fee on a wallet transaction T, creating a "bumper" transaction B.
T must signal that it is BIP-125 replaceable.
T's change output is decremented to pay the additional fee. (B will not add inputs to T.)
T cannot have any descendant transactions.
Once B bumps T, neither T nor B's outputs can be spent until either T or (more likely) B is mined.
Includes code by @jonasschnelli and @ryanofsky
Once we've picked coins and dummy-signed the transaction to calculate fee, if we don't have sufficient fee, then try to meet the fee by reducing change before resorting to picking new coins.

This change removes a mapValue.erase("version") statement which deletes a

865c3a2383 in 2010 and is harmless but confusing.
Remove the nType and nVersion as parameters to all serialization methods
and functions. There is only one place where it's read and has an impact
(in CAddress), and even there it does not impact any of the recursively
invoked serializers.
Instead, the few places that need nType or nVersion are changed to read
it directly from the stream object, through GetType() and GetVersion()
methods which are added to all stream classes.
Recent discussion (in IRC meetings, and e.g. #8989) has shown a
preference for the default confirm target for smartfees to be 6 instead
of 2, to avoid overpaying fees for questionable gain.
6 is also a compromise between the GUI's pre-#8989 value of 25 and the
bitcoind `-txconfirmtarget` default of 2. These were unified in #8989,
but this has made the (overly expensive) default of 2 as GUI default.

Assume that when a wallet transaction has a valid block hash and transaction position
in it, the transaction is actually there. We're already trusting wallet data in a
much more fundamental way anyway.
To prevent backward compatibility issues, a new record is used for storing the
block locator in the wallet. Old wallets will see a wallet file synchronized up
to the genesis block, and rescan automatically.

CTransAction::IsEquivalentTo was introduced in #5881.
This functionality is only useful to the wallet, and should never have
been added to the primitive transaction type.
It's reasonable that automatic coin selection will not pick a zero
value txout, but they're actually spendable; and you should know
if you have them. Listing also makes them available to tools like
dust-b-gone.
This is an advanced feature which will disable any kind of automatic
transaction broadcasting in the wallet. This gives the user full control
of how the transaction is sent.
For example they can broadcast new transactions through some other
mechanism themselves, after getting the transaction hex through `gettransaction`.
This just adds the option `-walletbroadcast=<0,1>`. Right now these
transactions will get the status
Status: conflicted, has not been successfully broadcast yet
They shouldn't be shown as conflicted at all (`walletconflicts` is empty). This status
will go away when the transaction is received through the network.
Adds a regression test for the wallet's ResendWalletTransactions function, which uses a new, hidden RPC command "resendwallettransactions."
I refactored main's Broadcast signal so it is passed the best-block time, which let me remove a global variable shared between main.cpp and the wallet (nTimeBestReceived).
I also manually tested the "rebroadcast unconfirmed every half hour or so" functionality by:
1. Running bitcoind -connect=0.0.0.0:8333
2. Creating a couple of send-to-self transactions
3. Connect to a peer using -addnode
4. Waited a while, monitoring debug.log, until I see:
```2015-03-23 18:48:10 ResendWalletTransactions: rebroadcast 2 unconfirmed transactions```
One last change: don't bother putting ResendWalletTransactions messages in debug.log unless unconfirmed transactions were actually rebroadcast.
