* Add "enough data" stop conditions for gov sync
* fix:
- make sure condition is checked only once per tick
- let condition be fully used on resync (reset nTimeNoObjectsLeft)
* fix verification network behaviour:
- use up to 10 connections only
- save state (do not ask same nodes after restart)
- initiate on time based intervals (every 5 minutes), based not on new blocks (should keep connections alive longer)
* revert mWeAskedForVerification serialization
* send verify requests using MAX_POSE_CONNECTIONS as a step
* fix watchdogs:
- do not accept if CreationTime is out of bounds (using CreationTime, not local time now)
- do not sync expired
- fix disk serialization
* drop watchdogs early, avoid adding//removing
* clean mapWatchdogObjects when object is deleted via votes
* Few networking fixes:
- skip "masternode"/inbound connections for sync related processes
- do not sync gov data to other nodes until fully synced ourselves
- do not accept incoming connections until fully synced
* inbound connections could be harmful only if our node is a masternode
* same for CGovernanceManager::Sync
* Update for OpenSSL 1.1 API.
* Update qt/paymentrequestplus.cpp for OpenSSL 1.1 API.
* Fix missing # in if for qt/paymentrequestplus.cpp fix for OpenSSL 1.1 API change.
* Fix indentation in src/qt/paymentrequestplus.cpp.
* Fix crash on initial mixing step:
- skip nodes marked to be disconnected
- add/release ref to make sure pnode is not deleted in the middle of the process
* - fix copy/paste mistake (nTries)
- let ConnectNode manage ref for non-mn pnodeFound
* Add last ping time to masternode_info_t
* Use thread safe functions to access mnodeman in masternodelist.cpp
* Fix masternodelist widget locking
* Protect access to widget data from StartAlias button
- vote should be removed when corresponding orphan vote expires
- fix CInstantSend::SyncTransaction: mapTxLockVotes is indexed by vote hash, not by tx hash (use votes from candidates and from orhpan vote map to avoid looping through the whole vote map)
* Adjust gov sync:
- simulate mainnet gov obj sync conditions on testnet
- add redundancy: ask up to 3 peers for the same obj
* stop loop if max number of peers per obj was asked
* 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
* Flag governance items when MN's are removed
* Remove old broken update mechanism
* Do not flag MN state changes which are irrelevant to validity
* Call AddGovernanceVote
* Remove vote count check from IsValidLocally
* Do not check voted validity flag when syncing
* Do not send objects marked for deletion during syncing
* Remove node penalty for unrequested objects.
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).
* On gov sync first sync objs, then ask for votes on per-obj basis from different peers.
This should help to sync obj list initially and split the load among many peers. Also adds ability to catch up votes later after the sync.
* ask for all objects, do this in cycles
* Fix Sync() code, better readability
* ask multiple nodes at once when possible, perf boost for large numper of objs
* Addressed comments: pass reference, more peer version check
Verification creates new conections, which we also use to sync but then we disconnect on ProcessMasternodeConnections every minute which at least could lead to excessive node load (for our peers). But could also interfere with sync process itself and we'd better keep them separate.
* Fix for incorrect locking in GetPubKey() (keystore.cpp)
* Fix Cmd-Q / Menu Quit shutdown on OSX
* Addition of ImmatureCreditCached to MarkDirty()
To protect against possible invalidation and to bring conformity to the code.
Fixing this https://bitslog.wordpress.com/2017/01/08/a-bitcoin-transaction-that-takes-5-hours-to-verify/
* Unit test for CScript::FindAndDelete
* Replace memcmp with std::equal in CScript::FindAndDelete
Function is stl; std::equal just makes more sense.
* Replace c-style cast with c++ style static_cast.
* Improve worst-case behavior of CScript::FindAndDelete
Thanks to Sergio Lerner for identifying this issue and suggesting this kind of solution.
* 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
* Few mn list sync changes:
- add more mn states
- only remove spent
- send mn ping in addition to mn announce on sync
- manage mn announces more carefully
- expire mns created from broadcasts with invalid ping
- old fWaitForPing logic for old nodes, should be helpful during migration period
This also adjusts active mn auto-start logic accordingly.
Should also store/check node we asked for mn list entry, not outpoint only. This should help to get mn list in sync when some nodes refuse to answer thus blocking such requests for the same outpoint for the next 3h and increasing mn list inconsistency.
- 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
* Make local address discovery more robust in CActiveMasternode
* parameter interaction: -masternode=1 -> setting -listen=1
* slightly postpone first run to give net thread a chance to connect to some peers
* make sure local address detected in CActiveMasternode::ManageStateInitial is valid
* Simplified address detection logic
- added description for 'deserialize'
- added 'type' filter to 'list'
- added 'count' command (changed CGovernanceManager::ToString to output a bit more detailed info)
* Change rate check logic to avoid DoS attacks
* Convert rate check to use object timestamp instead of arrival time
* Update cached variables before checking for superblocks
* Ensure that last times are monotonically non-decreasing
* Bump governance manager serialization format
* Improved rate check error reporting
