Pull request description:
We no longer send BIP 61 REJECT messages, so there's no need to set
a REJECT code in the CValidationState object.
Note that there is a minor bug fix in p2p behaviour here. Because the
call to `MaybePunishNode()` in `PeerLogicValidation::BlockChecked()` only
previously happened if the REJECT code was > 0 and < `REJECT_INTERNAL`,
then there are cases were `MaybePunishNode()` can get called where it
wasn't previously:
- when `AcceptBlockHeader()` fails with `CACHED_INVALID`.
- when `AcceptBlockHeader()` fails with `BLOCK_MISSING_PREV`.
Note that `BlockChecked()` cannot fail with an 'internal' reject code. The
only internal reject code was `REJECT_HIGHFEE`, which was only set in
ATMP.
This reverts a minor bug introduced in 5d08c9c579.

P2P and network changes
|
|
-----------------------
|
|
|
|
#### Removal of reject network messages from Dash Core (BIP61)
|
|
|
|
The command line option to enable BIP61 (`-enablebip61`) has been removed.
|
|
|
|
This feature has been disabled by default since Dash Core version 0.19.0.
|
|
Nodes on the network can not generally be trusted to send valid ("reject")
|
|
messages, so this should only ever be used when connected to a trusted node.
|
|
|
|
Since Dash Core version 0.20.0 there are extra changes:
|
|
|
|
The removal of BIP61 REJECT message support also has the following minor RPC
|
|
and logging implications:
|
|
|
|
* `testmempoolaccept` and `sendrawtransaction` no longer return the P2P REJECT
|
|
code when a transaction is not accepted to the mempool. They still return the
|
|
verbal reject reason.
|
|
|
|
* Log messages that previously reported the REJECT code when a transaction was
|
|
not accepted to the mempool now no longer report the REJECT code. The reason
|
|
for rejection is still reported.
|
|
|
|
Updated RPCs
|
|
------------
|
|
|
|
- `testmempoolaccept` and `sendrawtransaction` no longer return the P2P REJECT
|
|
code when a transaction is not accepted to the mempool. See the Section
|
|
_Removal of reject network messages from Bitcoin Core (BIP61)_ for details on
|
|
the removal of BIP61 REJECT message support.
