4a7a4ff1f1 developer-notes: add reference to snake_case and PascalCase
CamelCase is ambiguous as it refers to both lowerCamelCase and
UpperCamelCase, whereas PascalCase is only UpperCamelCase.

Merge #10865: Move CloseSocket out of SetSocketNonBlocking and pass socket as const reference
05e023f Move CloseSocket out of SetSocketNonBlocking and pass SOCKET by const reference in SetSocket* functions (Dag Robole)

Pull request description:

  Rationale:

  Readability, SetSocketNonBlocking does what it says on the tin.

  Consistency, More consistent with the rest of the API in this unit.

  Reusability, SetSocketNonBlocking can also be used by clients that may not want to close the socket on failure.

  This also moves the responsibility of closing the socket back to the caller that opened it, which in general should know better how and when to close it.

Merge #9622: [rpc] listsinceblock should include lost transactions when parameter is a reorg'd block
876e92b Testing: listsinceblock should display all transactions that were affected since the given block, including transactions that were removed due to a reorg. (Karl-Johan Alm)
f999c46 listsinceblock: optionally find and list any transactions that were undone due to reorg when requesting a non-main chain block in a new 'removed' array. (Karl-Johan Alm)

Pull request description:

  The following scenario will not notify the caller of the fact `tx0` has been dropped:

  1. User 1 receives BTC in tx0 from utxo1 in block aa1.
  2. User 2 receives BTC in tx1 from utxo1 (same) in block bb1
  3. User 1 sees 2 confirmations at block aa3.
  4. Reorg into bb chain.
  5. User 1 asks `listsinceblock aa3` and does not see that tx0 is now invalidated.

  See `listsinceblock.py` commit for related test.

  The proposed fix is to iterate from the given block down to the fork point, and to check each transaction in the blocks against the wallet, in addition to including all transactions from the fork point to the active chain tip (the current behavior). Any transactions that were present will now also be listed in the `listsinceblock` output in a new `replaced` array. This operation may be a bit heavy but the circumstances (and perceived frequency of occurrence) warrant it, I believe.

  Example output:
  ```Python
  {
    'transactions': [],
    'replaced': [
      {
        'walletconflicts': [],
        'vout': 1,
        'account': '',

  }
  ```

  I believe this addresses the comment by @luke-jr in https://github.com/bitcoin/bitcoin/pull/9516#issuecomment-274190081 but I could be wrong..

4d50f38 Support multi-block SHA256 transforms (Pieter Wuille)

Pull request description:

  This adds an SSE4 assembly version of the SHA256 transform by Intel, and uses it at run time if SSE4 instructions are available, and use a fallback C++ implementation otherwise. Nearly every x86_64 CPU supports SSE4. The feature is only enabled when compiled with `--enable-experimental-asm`.

  In order to avoid build dependencies and other complications, the original Intel YASM code was translated to GCC extended asm syntax.

  This gives around a 50% speedup on the SHA256 benchmark for me.

  It is based on an earlier patch by @laanwj, though only includes a single assembly version (for now), and removes the YASM dependency.

Merge #10775: nCheckDepth chain height fix
d9d1bd3 nCheckDepth chain height fix (romanornr)

Pull request description:

  ````
  if (nCheckDepth <= 0)
      nCheckDepth = 1000000000; // suffices until the year 19000
  if (nCheckDepth > chainActive.Height())
      nCheckDepth = chainActive.Height();
  ````

  These lines confuse me.
  Correct me if I am wrong, but we can't check any more blocks than we have right?
  If someone requests <= 0 it get set it into some huge number and then immediately limit it to the chain height in the following statement.
  ````
  if (nCheckDepth > chainActive.Height())
      nCheckDepth = chainActive.Height();
  ````
  when using ````--checkblocks=Z```` When Z is ````0```` or any other negative number, it will check all blocks.

  I think it should be changed to this maybe.
  ````
  if (nCheckDepth <= 0 || nCheckDepth > chainActive.Height())
      nCheckDepth = chainActive.Height();
  ````
  Which gets rid of that huge number which is confusing for any other altcoins that have a different block time.

Merge #10783: [RPC] Various rpc argument fixes
4dc1915 check for null values in rpc args and handle appropriately (Gregory Sanders)
999ef20 importmulti options are optional (Gregory Sanders)
a70d025 fixup some rpc param counting for rpc help (Gregory Sanders)

Pull request description:

  Audited where named args will fail to use correct default values or may fail when additional optional arguments are added.

  Previously for these parameters, it was fine to omit them as positional arguments, but it would trigger UniValue runtime errors to set them to null, or to omit them while passing named parameters with greater positions (which would internally set earlier missing arguments to null). Now null values are treated the same as missing values so these errors do not occur.

  Included a few other small fixes while working on it.

  I didn't bother fixing account-based rpc calls.

Merge #10817: Redefine Dust and add a discard_rate
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

  This partially reverts #9377. Would be nice to get this for 15 since its kinda crazy we have this option to begin with IMO, will need release notes as an RPC option is now ignored.

cf82a9e704 Do not allow users to get keys from keypool without reserving them
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.

Merge #10795: No longer ever reuse keypool indexes
1fc8c3d No longer ever reuse keypool indexes (Matt Corallo)

Pull request description:

  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.

  Builds on #10235, should probably get a 15 tag.

Merge #10707: Better API for estimatesmartfee RPC
06bcdb8da Convert named argument from nblocks to conf_target (Alex Morcos)
439c4e8ad Improve api to estimatesmartfee (Alex Morcos)

Pull request description:

  Through 0.14 branch, the estimatesmartfee API was tagged "WARNING: This interface is unstable and may disappear or change!" and this warning is removed for 0.15, so any wanted API updates should happen now.

  The changes here are to make the additional parameter for conservative estimates a more general estimate_mode string , to omit the feerate and include an error string instead of returning -1 on error, and to do better parameter checking initially.

  ~It is only the last 2 commits, but it's built on #10706 and #10543~.

  See https://github.com/bitcoin/bitcoin/pull/10707#issuecomment-314869251 for renaming of nblocks argument to conf_target.  Will need to be included before string freeze.

  PR description edited for clarity

Merge #9980: Fix mem access violation merkleblock
8276e70de Adding assert to avoid a memory access violation inside of PartialMerkleTree::CalcHash() (Chris Stewart)

Pull request description:

  Fixing a possible memory access violation in CPartialMerkleTree::CalcHash().

  This can happen if we some how a merkle tree with zero txids. I don't think this can happen in practice as we only send merkle block messages on the p2p network as of now -- we cannot receive them.

  This was found with #8469, specifically using this [generator](https://github.com/Christewart/bitcoin/blob/rapidcheck/src/test/gen/merkleblock_gen.h#L52-L77) which will cause a memory access violation on [this test case](https://github.com/Christewart/bitcoin/blob/rapidcheck/src/test/merkleblock_properties.cpp#L48).
