* Don't crash when spork15 is enabled but no MNs have been registered
* Don't bail out when no masternode payee is found
We should pay superblocks even if no masternode payee is found.
* Add missing newline to LogPrint call
* Handle review comments
* 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.
* Implement RemoveAskFor to indicate that we're not interested in an item anymore
When an INV item is received from the first node, the item is requested
immediately. If the same item is received from another node, an entry is
added to mapAskFor which marks the item for re-requesting in case the first
node did not respond. When the item is received from the first node,
the item was previously never removed from mapAskFor. Only the later getdata
loop in SendMessages would then gradually remove items from the map. This
is quite delayed however as the entries in mapAskFor have a timeout value.
RemoveAskFor allows to remove all entries from mapAskFor and setAskFor
when we are not interested in the item anymore (e.g. because we received
it already).
* Call RemoveAskFor whenever we receive a message
* Only pass hash instead of CInv object to RemoveAskFor
* Add pooled_secure_allocator and mt_pooled_secure_allocator
* Use mt_pooled_secure_allocator for BLS secure allocation
The old solution relied on thread-local-storage and was thus not compatible
to libc6 2.11 (which is the minimum supported version we use).
Also, the old solution turned out to be erroneous. It would have crashed
or memory leaked when ownership of CBLSPrivateKey would be handled over
to another thread.
* Add new header files to Makefile.am
* Fix copyright headers of new files
* Bail out early from secure deallocation
* Clean up global BLS keys when shutting down
* Remove global fDIP0003ActiveAtTip flag and always use VersionBitsState
fDIP0003ActiveAtTip was used much more often when introduced but turned out
to be not very useful in most places. Always use VersionBitsState now.
* Fix wrong use of VersionBitsState auto IX
* Make sure isAutoLockBip9Active flag is reset in case of chain reorgs
* Pass CCoinsView reference to special TX handling methods
* Allow referencing other TX outputs for ProRegTx collateral
* Remove "collateralAmount" from "protx register"
* Rename "protx register" to "protx fund_register"
* Remove UpdateSpork15Value from CDeterministicMNManager
Was not used/implemented anymore
* Lock masternode collaterals after chain/DIP3 is fully initialized
Otherwise detection of collaterals does not work.
* Implement new "protx register" RPC which uses existing collaterals
* Remove "masternode info" RPC
It is not consistent with other "masternode" RPCs anymore as it requires
the ProRegTx hash while all other RPCs work with the collateral.
* Load sporks from disk cache before initializing the chain
Otherwise spork15 is not loaded when we check it for the first time.
* Implement "protx info" RPC
* Use "protx info" instead of "masternode info" in DIP3 tests
* Test external collaterals for ProTx
* Handle review comments
* Don't pass CCoinView reference when it's not used
* Revert "Pass CCoinsView reference to special TX handling methods"
This reverts commit 28688724e112c8fe18e44aef055768dbbc068d7d.
* Use GetUTXOCoin instead of now removed coinsView
Also remove collateral height check as GetUTXOCoin only returns confirmed
coins.
* Add conflict handling for external collaterals to mempool
* Handle review comments (squashed Github suggestions)
Co-Authored-By: codablock <ablock84@gmail.com>
* Clear devNetParams and mimic behavior of other param types
Mainnet, testnet and regtest params are global and thus zero initialized,
we should mimic the same for devnet params.
Not doing so results in all kinds of issues on devnet.
* Remove unnecessary <string.h> includein chainparamsbase.cpp
* Allow to use low difficulty and higher block rewards for devnet
Configurable through -minimumdifficultyblocks, -highsubsidyblocks and -highsubsidyfactor
* Fix review comments
* Handle review comments
* Remove nProtocolVersion fields from deterministic masternode lists
This field was part of my initial implementation from DIP3. One of the last
changes of DIP3 was then to remove this field, which I did not bring back
into code yet. This commit removes it now.
We use PROTOCOL_VERSION now in cases were compatibility in the the pre-DIP3
list is needed.
* Add type and mode fields in DIP3 special TXs
These were added to DIP3 but not in-code yet.
* Add DMN_PROTO_VERSION
* Use BLS keys for operator keys
* Add "bls generate" RPC to generate BLS keys
* Use unique_ptr to store blsKeyOperator and blsPubKeyOperator
Needed because the Chia BLS library crashes when keys are created before
the library is initialized, even if keys are not used. This is the case here
as we have static instances here.
* Remove unnecessary CheckSignature calls
This seems to be some garbage I left in by mistake.
* Fixed review comments
* Fix rpc help for operator keys
All keys that are used as examples are random. None of the secret keys
belongs to any of the public keys.
* Use .GetHash() instead of ::SerializeHash() for BLS pubkeys in txmempool.cpp
* Rename mapProTxBlsPubKeys to mapProTxBlsPubKeyHashes
* Move handling of size >= SerSize into SetBuf/GetBuf
Instead of performing this in the individual implementations of
InternalSetBuf and InternalGetBuf
* Assert that size if GetBuf is always SerSize
* 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
* Alternative solution: pick rounds with the most inputs available to mix first
* randomly skip some inputs when we have at least one of this denom already
* More randomization in PrepareDenominate
* fix `vecSteps[nBit] >= 1 ?` and adjust speed/privacy ratio for more speed i.e. `GetRandInt(5) == 0`
* fix typos
* no comments
* remove vector, extra loop in cleanup function
This commit removes 2 loops and a vector which I don't believe are necessary in
CMasternode::FlagGovernanceItemsAsDirty. I could be missing something, but
can't think of any good reason why this was implemented this way.
* use range operator to range over vectors
* remove deprecated wire message types
* mn: simplify govobj map mgmt a bit
* remove extra semicolons
* invert if/else condition and drop else
* remove if/else logic from Qt
This is the entire purpose of the Get<X>String methods on MNP class.
* Revert "remove deprecated wire message types"
This reverts commit 9de88a3fda999555c00cb829d60e322b2fd3800d.
* Revert "remove if/else logic from Qt"
This reverts commit c0f43c9b85274b13a3ac9625775817bc5b53bb9d.
These cause crashes when used in for loops. Reason is very likely that
temporary CDeterministicMNList objects are destroyed before entering the
loop while the adaptors rely on these objects.
Discovered in one of our devnets while calling "protx list"

* rename vars in mnsync to make more sense
nRequestedMasternodeAssets -> nCurrentAsset
nRequestedMasternodeAttempt -> nPeerCount
* rename var to nTriedPeerCount
* 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

* removes replace-by-fee.py
* remove help text related to rbf
* remove comment text relating to rbf
* remove "-mempoolreplacement" cli option
* Remove (effectively dead) RBF code which would never have been called anyway and some assosiated variables
* since `setConflicts` is always empty, this is dead code
* Since we don't have RBF, don't have to do this check. Also, since `setConflicts` is always empty this is dead code
* removes unneccesary if as it will always be true
* remove unused `set<uint256> setConflicts`
* Removes replacement of conflicting txs, as conflicting txs are never accepted
* removes RBF from `validForFeeEstimation`

* fix typo in 82898b0
* remove unused fEnableReplacement in validation.h
* remove the removal reason REPLACED in txmempool.h
* removed unused variable
* comment typo
* Fix crash bug with duplicate inputs within a transaction
Introduced by #9049
* Remove redundant parameter fCheckDuplicateInputs from CheckTransaction
While importing, IsInitialBlockDownload always returns true, meaning that
the call to UpdatedBlockTip will also receive true as fInitialDownload.
UpdatedBlockTip is never called again unless a block is mined.
Mining of new blocks in regtest however only starts after mnsync has
finished, which will never happen as it waits for the next call to
UpdatedBlockTip.
* Don't use GetTransaction in CheckProUpRegTx
GetTransaction locks mempool.cs internally. This brings messes up the locking
order of cs_main, mempool.cs and CCheckQueue::ControlMutex.
* Lock cs_main in TestChainSetup::CreateBlock when updating CbTx
* Implement IS Double spend notifications in zmq
* copy/paste error
* typo
* Send both conflicting and conflicts against as ZMQ notifications
* CTransaction based not hash based
* @UdjinM6 requested changes
* Implement temporary solution to allow voting with owner keys from your wallet
Will later be removed and properly reimplemented when cleaning up
legacy masternode code
* When MN keys from masternode.conf are used, only allow voting when they match with keyIDVoting
* Implement dip3 integration tests
This tests the full upgrade path from legacy MNs to deterministic MNs
* Invoke UpdatedBlockTip signal when invalidateblock RPC is called
Currently, UpdatedBlockTip would only be called if the invalidation resulted
in another chain becoming the longest one. This is inconsistent behavior
and was spotted when running dip3 integration tests.
* Lean towards "from high to low" branch but still mix via "from low to high" one someties
* Try to mix non-duplicate txids only
* Lean towards edges but still mix starting from the middle sometimes
If failed when started from the middle try mixing from the edges right away.
Note: liqudity providers always start from 0
* map -> set
* Refactor nRoundStart calculations
1. Enforce payment to masternodes in IsBlockPayeeValid even if superblocks
are triggered. This new rule only gets activated when spork15 activates.
2. Always enforce masternode payments when spork15 is activated and ignore
spork8 in that case. spork8 can be removed after spork15 activation
and hardening of the spork15 height into consensus params.
* Cleaned up brackets on if, while, for, BOOST_FOREACH. Some whitespace fixes
* gov, mn and mining cleanup
* Revert "Cleaned up brackets on if, while, for, BOOST_FOREACH. Some whitespace fixes"
This reverts commit 4a2a1b0645c5195025d0c7e6dad2e01a93efbfd6.
* Revert "gov, mn and mining cleanup"
This reverts commit 7cb91aabc67df0ab60db4ee84e3aaaf6cf6b7881.
* cleanup some dash specific
* "if(" -> "if (" "for(" -> "for (" + corrected some else blocks
* Split PS into Manager and Session
* Adjust log messages accordingly
* add -privatesendsessions cmd-line option
* address review comments
* bump MAX_OUTBOUND_MASTERNODE_CONNECTIONS to 30
+10 for parallel mixing
* protect vecSessions
* constructors
* Rewrite CMasternodeMan::ProcessMasternodeConnections() to use CPrivateSendClientManager::GetMixingMasternodesInfo().
This should solve potential deadlock cs_vecqueue vs cs_vNodes.
* Drop no longer used IsMixingMasternode()
* lock cs_wallet when mixing uses balance related functions
* Split keyIDMasternode into keyIDOwner/keyIDOperator/keyIDVoting
keyIDOwner is the key used for things which should stay in control of the
collateral owner, like proposal voting.
keyIDOperator is the key used for operational things, like signing network
messages, signing trigger/watchdog objects and trigger votes.
keyIDVoting is the key used for proposal voting
Legacy masternodes will always have the same key for all 3 to keep
compatibility.
Using different keys is only allowed after spork15 activation.
* Forbid reusing collateral keys for operator/owner keys and vice versa
* Bump SERIALIZATION_VERSION_STRING in CMasternodeMan
* Support help for masternode rpc call subcommands
* Support help for gobject rpc call subcommands
* squash ifs for conditions to show help
* remove code duplication for masternode list and masternodelist help calls
* Pass consensus params to ContextualCheckTransaction
As we do with ContextualCheckBlock
* Use ContextualCheckTransaction in ContextualCheckBlock instead of duplicating the check
* Fix pindexPrev parameter signature in ContextualCheckTransaction
The SporkMessage is a lower-level construct which shouldn't be aware of
SporkManager. This commit moves the `sporkManager.IsSporkActive()` calls
outside the SporkMessage functions. This follows the dependency injection
pattern and makes it easier to test SporkMessage as well.
* adds rpc calls for `setprivatesendrounds` and `setprivatesendamount`
* tabs -> spaces
* @gladcow change request
* Whops tab -> spaces
* @Udjin changes, not the CAmount -> int
* int stuff
* Throw error when rounds / amount isn't within range
* Prepare for DIP3 operator reward payments and switch to array in getblocktemplate
This commit allows to later split MN rewards into multiple recipients, e.g.
the owner reward and operator reward. It also updates the getblocktemplate
output to return an array of MN payments instead of a single entry.
This should allow MN miners and pool operators to prepare themself for the
upcoming changes in regard to operator rewards.
* txoutsMasternode -> voutMasternode
* More renaming
* Consider all masternode payments when looking for a known masternode
* Add stdin, stdout, stderr to ignored export list
* Merge #13171: Change gitian-descriptors to use bionic instead
c1afe3232fa10e290fb355cf37ea4c7bc1084065 Change gitian-descriptors to use bionic instead (Chun Kuan Lee)
Pull request description:
I have tested this with Ubuntu Bionic host with lxc 3.0.0, the gitian-build for Windows and MacOSX work fine, but there is an issue about it for Linux. Failed at check-symbol:
```
test/test_bitcoin: symbol __divmoddi4 from unsupported version GCC_7.0.0
test/test_bitcoin: symbol log2f from unsupported version GLIBC_2.27
qt/bitcoin-qt: symbol __divmoddi4 from unsupported version GCC_7.0.0
qt/bitcoin-qt: symbol log2f from unsupported version GLIBC_2.27
```
I think this should be fixed in `./configure --enable-glibc-back-compat`
Should not be merged before #13177devrandom/gitian-builder#178Close#12511
Tree-SHA512: 257d75d5b6864e105279f7a7b992fbbd7903cdbe3300b66dacec0a783d267707d9dbbfe0e64a36983ca1eca50a2a5e1cdb222b6d3745ccc3e5fc5636c88b581f
* Use IN6ADDR_ANY_INIT instead of in6addr_any
This is the same fix as fc6a9f2ab1
Couldn't backport the original commit as we are missing some refactorings.
* CSporkManager class serialization
* Read/write sporks.dat file
* Move mapSporks into CSporkManager and serialize it
* fix GetSporkByHash
* spork tests
* add missed cs lock
* clear mapSporksByHash in CSporkManager::Clear
* use spork active rpc call to hide spork inner logic
* set small pause between rpc calls in cycles
* Refactor block payee filling/validation
1. Move out old budget validation into it's own function (IsOldBudgetBlockValueValid)
2. Refactor IsBlockValueValid to bail out early instead of using deep
nested if/else blocks. IMHO, I feel that this makes the code much easier
to read and less error prone.
3. Refactor/rename CreateSuperblock and CMasternodePayments::FillBlockPayee
to be getters without actually modifying the coinbase TX. The coinbase
is now only modified from the global FillBlockPayments function. Makes
later changes in DIP3 easier (allowing superblock and MN rewards in same block)
* Use __func__ for logging in block payee code
* Fix code style nit
* Split CActiveMasternode into CActiveMasternodeInfo and CLegacyActiveMasternodeManager
* Use CKeyID instead of CPubKey whenever possible in masternode code
* Rename activeMasternode to activeMasternodeInfo and make it a struct
* Rename pubKeyIDXXX to keyIDXXX
* Bump SERIALIZATION_VERSION_STRING
* Fix build error after rebase
* Fix compilation warning/error with clang
* Allow changing budget parameters for regtest
* Lift some limitations for local addresses for masternodes in regtest
Needed to make masternodes works in regtest mode
* Add "masternode check" RPC to force invocation of CheckAndRemove
Useful in integration tests where MN lists must be predictable
* remove instandsenddepth option
* remove CInstantSend::GetConfirmations
* Explicit IXlocks processing in the code using GetDepthInMainChain
* remove dummy confirmations for IX locks
* remove unused constant
* Track IS status in TransactionStatus
* Highlight IS in tx list

* Drop `swap` and `=` in GovernanceObject
Were used for shuffling, no longer needed
* Replace Dash-specific threads with scheduled tasks
* Fix rare crash when trying to shutdown wallet during mixing
Should stop PS and release all keys _before_ wallet is destroyed.
* fix nowallet
* update doc
* GCC-7 and glibc-2.27 compat code
* Statically link libstdc++ for GCC based builds
Makes sure binaries which are built on a newer build host still work
on older distros.
* Use python3 when installing MacOS native tools
* Move actual build logic out of Travis and upgrade to gcc-7
Travis will now simply call a few scripts which do the actual work.
These scripts will first create a "builder image" which contains the
necessary environment for the actual build. Then scripts are called
inside this builder image to do the build.
This should make us more independant from Travis and also allows us
to do local CI testing.
The build matrix is also moved out of .travis.yml and instead moved
into ci/matrix.sh. This script is sourced with only "BUILD_TARGET" being
set so that it internally can figure out which other environment
variables need to be set.
This commit also upgrades the used GCC version to 7. This is due to the
use of ubuntu:bionic as base image for the builder image.
* Add Jenkinsfiles for regular CI and nightly gitian builds
* Automatically download OSX SDK in gitian-build.sh
* Remove bogus "export MAKEJOBS=-j5"
* Forward cache/src dirs into builder container
Fixes caching issues on Travis.
* fix
* Fail build immediately when building depends took too long
* replace map count/insert w/emplace in instantx.cpp
This feels like an optimization, something about:
```
if map.count(key)
return false
else
insert(pair)
return true
```
... just feels icky. Plus, `vote.GetMasternodeOutpoint()` is only called
once. The previous version might be slightly more readable, however.
* use std::pair template constructor shortcut
* fix whitespace
* added zmq stuff for governance objects and votes
it seems that zmq is currently not in a working state, need to figure that out.
Need to:
plug in the new methods added
possibly plug in the old methods, as it doesn't look like they are.
* formatting fix. Will probably need to revert for this PR
* continue linking new zmq messages in
* added comment, might need to revert
* fixes error of it not knowing about the classes
* Actually link in, all new govobjects and govvotes should be broadcast over zmq now.

* Allows a user to mix up to 16 rounds
All codebase appears to accept up to 16 rounds, however this form was capped at 8; restricting users to 2-8 rounds. This commit allows a user to actually use up to 16 rounds in practice. This will greatly enhance the privacy of those very worried about their privacy, as well as possibly increasing liquidity and increasing the privacy of all users.
* Up the default for PS mixing to 4 rounds.
* replace boost casts in dash-specific code
Specifically for spork.cpp : this should be temporary until all spork
sigs are based on hash and not string serialization format, after which
I expect the old signatures (else branch) should go away altogether. But
I still think it's worth it to get pieces of the boost dependency
removed, and this is an easy win, and could be merged now or in a patch
release w/o issue.
* replace boost::shared_ptr w/std::shared_ptr
