* Don't rely on UTXO set in CheckCanLock
The UTXO set only works for TXs in the mempool and won't work when we try
to retroactively lock unlocked TXs from blocks.
This is safe as ProcessTx is only called when a TX was accepted into the
mempool or connected in a block, which means that all input checks were
good.
* Rename RetryLockMempoolTxs to RetryLockTxs and let it retry connected TXs
* Instead of manually calling ProcessTx, let SyncTransaction handle all cases
SyncTransaction is called from AcceptToMemoryPool and when transactions got
connected in a block. So this is the time we want to run TXs through
ProcessTx. This also enables retroactive signing of TXs that were unknown
before a new block appeared.
* Test retroactive signing and safe TXs in LLMQ ChainLocks tests
* Also test for retroactive signing of chained TXs
* Honor lockedParentTx when looking for TXs to retry signing
* Stop scanning for TXs to retry after a depth of 6
* Generate 6 block to avoid retroactive signing overloading Travis
* Avoid retroactive signing
* Don't rely on NewPoWValidBlock and use SyncTransaction to build blockTxs
NewPoWValidBlock is not guaranteed to be called when blocks come in fast.
When a block is accepted in AcceptBlock, NewPoWValidBlock is only called
when the new block is a successor of the currently active tip. This is not
the case when after the first block a second block is accepted immediately
as the first block is not connected yet.
This might be a bug actually in the handling of NewPoWValidBlock, so we
might need to check/fix this later, but currently I prefer to not touch
that part.
Instead, we now use SyncTransaction to gather TXs for blockTxs. This works
because SyncTransaction is called for all transactions in a freshly
connected block in one go. The call also happens before UpdatedBlockTip is
called, so it's fine with the existing logic.
* Use tx.IsCoinBase() instead of checking index 0
Also check for empty vin.
* Unify autoIS/send_smth functions
* Rename autoix-mempool.py -> autois-mempool.py
* Make sure create_raw_trx produces expected results
* Make sure sender has enough inputs and nodes are synced before starting the actual test
* Mine one block to clean mempool up
* 2 blocks is enough for IS on regtest
This also unifies it across different IS tests
* Allow wait_for_instantlock to be called on any node, not only on the one that has the tx in the wallet
* No need to query for tx this often in wait_for_instantlock
* Rename create_raw_trx -> create_raw_tx
* Fund sender with a single TX instead of 30
* Require only 3 out of 5 signatures for old InstantSend in regtest mode
* Use LLMQs of size 5 with threshold of 3 for regtest
* Fix wrong check for out-of-range bits in CFixedBitSet
* Reduce number of masternodes in masternode/LLMQ tests
* Add missing \n to LogPrintf call
* Use correct indexes for isolated/receiver/sender nodes
The way it was before resulted in nodes 1-3 being unused and 6-8 being used
for these 3 special nodes even though these are masternodes.
* Avoid stopping/starting isolated node in p2p-instantsend.py
It's enough to disable networking for this node.
* Fix remaining `print`s in tests
* use AssertLockHeld(cs) instead of relying on comments
* actually use `clsig` in `EnforceBestChainLock()`
* fix log output in `EnforceBestChainLock()`
* drop comments
* Implement copy_datadir to allow easy copying of state from one node to another
* Instead of starting with a fresh datadir for MNs, reuse a copy of the faucet
* Start masternodes in parallel instead of waiting for the previous to finish
* Allow specifying of window and threshold with -bip9params
* Implement -dip3activationheight for regtests
* Implement fast DIP3 activation in DashTestFramework
* Speed up activation of DIP3 in dip3-deterministicmns.py
* Update qa/rpc-tests/test_framework/test_framework.py

* Always assign fast_dip3_activation
* Speed up autoix-mempool tests by making the max mempool smaller
With this less TXs have to be created to fill up the mempool.
* Change DashTestFramework to use DIP3 MNs
* Don't assert disabled bip9 in p2p-autoinstantsend.py
* no `-debug` by default (it's too heavy)
* drop useless `sync_masternodes` calls and add a couple where they could be actually usefull
* change autoix-mempool.py test logic:
1. use separate nodes to send test txes
2. sync nodes while filling the mempool
* Add BIP9 parameters for DIP3 deployment on testnet
* Remove autoix BIP9 deployment and reuse DIP3 deployment
* Add BIP9CheckMasternodesUpgraded to chain params
This controls if miners should check for upgraded masternodes first before
adding BIP9 bits to the block version. This only makes sense in network
where masternodes are up and running before BIP9 activation, which is not
necessarely the case in regtest and devnet.
Also refactor ComputeBlockVersion to use fCheckMasternodesUpgraded instead
of the inverse fAssumeMasternodeIsUpgraded. It is set to false by default
and only set to true in CreateNewBlock.
* Check for upgraded masternodes for DIP3 activation (only mainnet and testnet)
* Bump PROTOCOL_VERSION and DMN_PROTO_VERSION
We probably have nodes with 70211 already running on testnet.
* create base class for dash-specific tests
* use common base class in p2p-autoinstantsend.py
* use common base class in p2p-instantsend.py
* rename check_IX_lock to wait_for_instantlock
* fix issue with trx amounts precision in autoix-mempool.py
* fix issue with trx amounts precision in p2p-autoinstantsend.py
* fix issue with trx amounts precision in p2p-instantsend.py
* Rallback adding empty line
* Rallback adding empty line
* fix CTxLockRequest::GetMinFee()
* Force regular IS txes to include MIN_FEE * n_inputs fee on creation regardless of auto-IS status
* set_autoix_spork_state should bump mocked time
* make sure IS fee matches the expected one
* turn off spork16 and test all types of txes again
* add locktransaction rpc call
* Remove special instantsend fee for simple transactions
* Function to check if trx is simple enough to be autolocked
* Automatic lock for all received from peers simple trxes
If we get a new transaction with CInv message and it is "simple" and
is accepted in mempool, we initiate its lock. We don't lock orphan trxes
that accepted in mempool after this trx because they are locked by other
peers.
* Automatically lock simple trxes in wallet
* protocol bump for InstantSend without special fee
* Add function to detect used mempool share
* Mempool threshold for auto IX locks
* Add SPORK_16_INSTANTSEND_AUTOLOCKS spork
* Make autolocks active only when spork SPORK_16_INSTANTSEND_AUTOLOCKS is active
* BIP9 autolocks activation
* revert increasing min peer protocol version for mn rank
* move IsTrxSimple check to CTxLockRequest class
* make MAX_INPUTS_FOR_AUTO_IX private member of CTxLockRequest class
* make AUTO_IX_MEMPOOL_THRESHOLD private member of CInstantSend class
* remove locktransaction RPC call
* tests for automatic IS locks
* fix mempool threshod calculation
* bump mocktime in activate_autoix_bip9
* set node times
* no need to spam the node with gettransaction rpc requests that often
* use `spork active` instead of leaking spork logic into tests
* codestyle fixes
* add test description in comments
* fix typo
* sync test nodes more often during BIP9 activation
* Use 4th bit in BIP9 activation
* Fix comments according codestyle guide
* Call AcceptLockRequest and Vote at the first node creating autoix lock
* fix mempool used memory calculation
* rallback not necessary change in CWallet::CreateTransaction
* test for stopping autolocks for full mempool
* Inject "simple autolockable" txes into txlockrequest logic
