* Implement BIP 9 GBT changes
- BIP9DeploymentInfo struct for static deployment info
- VersionBitsDeploymentInfo: Avoid C++11ism by commenting parameter names
- getblocktemplate: Make sure to set deployments in the version if it is LOCKED_IN
- In this commit, all rules are considered required for clients to support
* qa/rpc-tests: bip9-softforks: Add tests for getblocktemplate versionbits updates
* getblocktemplate: Explicitly handle the distinction between GBT-affecting softforks vs not
* getblocktemplate: Use version/force mutation to support pre-BIP9 clients
* Don't use floating point

* Send tip change notification from invalidateblock
This change is needed to prevent sync_blocks timeouts in the mempool_reorg
test after the sync_blocks update in the upcoming commit
"[qa] Change sync_blocks to pick smarter maxheight".
This change was initially suggested by Suhas Daftuar <sdaftuar@chaincode.com>
in https://github.com/bitcoin/bitcoin/pull/8680#r78209060

* torcontrol: Explicitly request RSA1024 private key
When generating a new service key, explicitly request a RSA1024 one.
The bitcoin P2P protocol has no support for the longer hidden service names
that will come with ed25519 keys, until it does, we depend on the old
hidden service type so make this explicit.
See #9214.

* protect mapRejectedBlocks by cs_main
* few block reprocessing fixes:
- DisconnectBlock should fail on DisconnectTip failure
- ResolveConflicts should fail on DisconnectBlock failure
- ReprocessBlocks cleanup
* don't ban on IsBlockValueValid/IsBlockPayeeValid failure
* Multi-quorum InstantSend, complete refactoring
+ cleanup for IS and partial protobump
* more changes:
- allow InstantSend tx to have 10 inputs max
- store many unique tx hashes in mapVotedOutpoints
- more checks in AcceptToMemoryPoolWorker (moved from ProcessMessage + CTxLockRequest(tx).IsValid() )
* More changes:
- let multiple lock candidates compete for votes
- fail to vote on the same outpoint twice early
* More changes:
- notify CInstantSend on UpdatedBlockTip -> remove cs_main from CheckAndRemove()
- notify CInstantSend on SyncTransaction -> count expiration block starting from the block corresponding tx was confirmed instead of the block lock candidate/vote was created
- fixed few locks
* add comments about nConfirmedHeight
* Fix "Block vs Lock" edge case
* Fix "Block vs Lock" edge case, p2
* Fix issues:
- fix logic for locking inputs and notifying - see UpdateLockedTransaction, TryToFinalizeLockCandidate
- add missing hash inserting in ProcessTxLockVote
- add nMaxBlocks param to ResolveConflicts to limit max depth allowed to disconnect blocks recursively
- fix false positive mempool conflict
- add missing mutex locks
- fix fRequireUnspent logic in CTxLockRequest::IsValid
We should remove hash from setAskFor when the message corresponding to previous inv arrives, otherwise it's stays there forever and setAskFor overflows (i.e. AskFor returns immediately without processing).
* Store time we saw mnb last time, bump sync timeout
if we received seen mnb but we are too close to MASTERNODE_NEW_START_REQUIRED_SECONDS
* Reset blockchain sync status if new blocks were accepted during sync
* Add some debug log output
* wait for at least one new block to be accepted
* bump CGovernanceManager-Version
- some were not used, some were included twice, some were in the wrong place, some were missing (but it compiled because some were in the wrong place)
- organized a bit better, grouped dash specific includes in original bitcoin files, should save some time solving conflicts when/if merging patches later
* Revert behaviour introduced in 5e1a6afe7f, make nLastDsq local variable instead of being network-wide one. Should fix mixing for new clients and for those who was offline for too long.
* fix docs
- avoid processing same vote multiple times
- do not relay votes until synced
- do not ban for wrong signature of old votes
- do not check masternode ranks for old votes on regular (non-MN) nodes
* refactor IsBlockValueValid to return actual error string, use it in error message for bad-cb-amount
* make error messages in IsBlockValueValid even more verbose
* locks in PS
* lock in governance
* locks in IS
* lock in ProcessGetData
* locks in CMasternodeSync
* centralize mnodeman.Check call
* locks order in mnpayments
* use current block chainTip when possible (less locks)
* add missing lock in CountInputsWithAmount
* fix deadlock RequestLowDataPaymentBlocks/IsTransactionValid
* LOCK2 in CheckMnbAndUpdateMasternodeList, CheckAndUpdate, SendVerifyRequest
* LOCK(cs) is not needed here
* Decouple governance init actions from serialization
Should fix this:
```
Assertion failed: lock governance.cs not held in governance-classes.cpp:117; locks held:
cs_Shutdown init.cpp:200 (TRY)
cs ./governance.h:195
cs governance.cpp:835
Abort trap: 6
```
- TXLOCKREQUEST should be processed as normal tx plus some custom logic, should not "fake" inventory
- should not create "fake" local lock, should instead keep track of orphan votes and reprocess them when corresponding TXLOCKREQUEST arrives
- orphan vote time map should be indexed by full outpoint, not by txid of mn collateral
bump MIN_INSTANTSEND_PROTO_VERSION
* slightly refactor IS:
- the only place where logic is changed: `ProcessTxLockVote()` - it should first try to find mn and fail if none was found and only then try to call `GetMasternodeRank()` (which is heavy)
- fixed few `cs_main`
- slightly optimized number of `tx.GetHash()` calls
- lots of `const` (fixed few related functions in main.cpp)
- few smaller fixes: iterators, log output, comments, etc
- use thread safe methods of mnodeman
- safety check in GetAverageUnknownVoteTime
* Added net logging messages in main.cpp
* Added logging for trigger removal
* Improved log message for CGovernanceManager::UpdatedBlockTip
* Improved log messages in CGovernanceManager::UpdateCachesAndClean
* Added more logging to CGovernanceTriggerManager
* Check vote validity before pushing inventory during sync
* Add triggers to map after loading governance.dat file
* fix dstx acceptance
* two more fixes:
- do not re-verify dstx once accepted
- fix dstx prioritization
* return early for dstx conditions, more log verbosity
Followup for the recent winner_block PR (#1028) and name confusion discovered during code review.
"Mostly" because also:
- CMasternodeBlockPayees::GetPayee -> CMasternodeBlockPayees::GetBestPayee which describes what this function is actually doing a bit better imo;
- fixing constructor CMasternodePaymentVote empty constructor
* store vote hashes in CMasternodePayee and use them in CMasternodePayments::Sync
* Request low data payment blocks in batches directly from some node instead of/after preliminary Sync.
* remove nVotes
- rename all 3 instantsend sporks
- remove SPORK_7_MASTERNODE_SCANNING (not used anymore)
- change `_DEFAULT` for spork 2 and 3, adjust comments for for them
- fix GetSporkNameByID() (should not return smth_DEFAULT)
b6b6d6c Added nSuperblockStartBlock, adjusted testnet/regtest params
15a3c64 More for governance block checks, p1 (non-compilable):
- add GetPaymentsLimit() and GetPaymentsTotalAmount()
- IsValidBlockHeight() should check nSuperblockStartBlock
- CSuperblock::IsValid should check payment limit and miner payout
- no cs_main
- slightly refactored related things
e8f9e5d More for governance checks, p2 (compilable):
- IsBlockValueValid(), IsBlockPayeeValid() and FillBlockPayee() rewritten, no cs_main for them
- CreateNewBlock adjusted, need more work on CBlockTemplate (see TODO)
- moved (and simplified) IsBlockPayeeValid() call from CheckBlock() to ConnectBlock()
51434cf Add ability to calculate only superblock part of subsidy in GetBlockSubsidy()
aa74200 Fix GetPaymentsLimit()
f7b6234 braces and comment
ade8f64 more checks for IsValidBlockHeight()
068c178 Added DBG macro in util.h to facilitate debugging
- This macro allows debugging statements (typically printf's or cout's) to
be activated or deactivated with a single comment. Uncomment the line:
//#define ENABLE_DASH_DEBUG
in util.h to enable debugging statements.
- When commented any code wrapped with the DBG() macro will simply be removed
by the preprocessor. When not commented all such wrapped statements will
be present.
- For maximum effectiveness it is best that util.h be the first effective include
in all source files. It is also possible to enable the macro for a single file
by temporarily adding #define ENABLE_DASH_DEBUG to the top of the file.
- Code committed to non-development branches should always have the define
commented.
d125d9b V0.12.1.x -- merging trigger/generic object/superblock changes for testnet phase II
- This commit contains the core governance system changes for 0.12.1. Any unrelated
changes have either been removed or moved to separate commits.
120724c File mode fixes
- Changed mode 0755->0644 on several source files.
c7f9e11 Updated todo reminders
- Added reminder to revert temporary reduction of number of votes
required to trigger superblock to 1 for testing
92adc98 Made CSuperblockManager::IsValidSuperblockHeight an inline function
- This is for efficiency since this function is called often and is
only 1 line of code.
c050ed7 Added comment explaining rationale for no LOCK(cs) in CSuperblock::IsValid
dc933fe Removed unused CSuperblockManager::IsBlockValid function
decec88 Moved calls to SuperblockManager::IsValidSuperblockHeight into IsSuperblockTriggered.
- Since calls to the later function are always protected by the former there's
no reason to keep these separate and this simplifies the code in
masternode-payments.cpp.
8672885 Reestablished expected value check for non-superblocks in IsBlockValueValid
b01cbe0 Changes to IsBlockValueValid to fix rpc test failure
a937c76 Changed include order to allow per file activation of the DBG macro
d116aa5 Fixed IsValidSuperblockHeight logic
- Note this has an effect on testing because we can now only create
1 superblock per day. Devs may need to temporarily change testnet params
for easier testing.
2d0c2de Convert superblock payments to CAmount
- We assume that payment values in JSON are in units of DASH
for consistency with other RPC functions, such as
createrawtransaction.
376b833 Revert temporary testing value for nAbsVoteReq
- Also ensure that number of votes required is never smaller than 1
8c89f4b Cleaned up CSuperblock error handling
- Exceptions are now thrown consistently rather than using a mix of
exceptions and return code checking. Exceptions are now caught only
in AddNewTrigger when the CSuperblock constructor is called. Unnecessary object
status members have been removed.
d7c8a6b Removed utilstrencodings header
- This appears to help with travis tests, for unknown reasons.
c4dfc7a Fixed some minor code review issues
63c3580 Reverted locking change in miner.
- This should have been done in the original PR but was overlooked.
4ab72de Fixed variable name to match common practice and bracket formatting
886a678 Improvements to vote conversion code
- Replaced redundantly defined function with inclusion of governance-vote.h
- Replaced magic numbers with their corresponding constant symbols
0a37966 Reordered governance message handling
86d8505 Refactor CActiveMasternode
+ move strMasterNodeAddr to CActiveMasternode
a005c79 Refactor InstantSend
+ new lock cs_instantsend to protect maps on CleanTransactionLocksList()
+ new DEFAULT_INSTANTSEND_DEPTH constant
+ rename MIN_INSTANTX_PROTO_VERSION to MIN_INSTANTSEND_PROTO_VERSION and bump it
d24182c Refactor Privatesend
+ decouple from util.h and version.h
+ more functions for CDarksendBroadcastTx: constructors, signing, serialization
+ move from rand() to insecure_rand() in general but to GetRand() for session id
+ fix defaults
- mn hash compatibility with 70103
- ignore some requests while syncing
- fix locking/initializing in sync
- do not ban for old mnw
- split budget/governance messages/invs
42bdf42 Refactor/fix spork:
- move ProcessSpork, GetSporkValue, IsSporkActive, ExecuteSpork and mapSporksActive to CSporkManager
- move Sign, CheckSignature, Relay to CSporkMessage
- move ReprocessBlocks out of sporks to main.cpp / rename DisconnectBlocksAndReprocess to DisconnectBlocks
- rename SporkKey to SporkPubKey
- bugfix: only set strMasterPrivKey if spork signature produced by that key was verified successfully
- few log format changes, cleaned up includes
