Alexander Block 66a2cdeafc Properly handle conflicts between ChainLocks and InstantSend (#2904)
* Move code to write archived ISLOCKs into its own method

We'll need this from another method as well later.

* Return ISLOCK instead of conflicting txid in GetConflictingTx/GetConflictingLock

* Implement GetInstantSendLocksByParent and RemoveChainedInstantSendLocks

These allow to easily delete multiple chains (actually trees) of ISLOCKs
in one go.

* Implement RemoveConflictedTx and call it from RemoveMempoolConflictsForLock

Also add "retryChildren" parameter to RemoveNonLockedTx so that we can
skip retrying of non-locked children TXs.

* Properly handle/remove conflicted TXs (between mempool and new blocks)

* Track non-locked TXs by inputs

* Implement and call ResolveBlockConflicts

* Also call ResolveBlockConflicts from ConnectBlock

But only when a block is known to have a conflict and at the same time is
ChainLocked, which causes the ISLOCK to be pruned.

* Split out RemoveChainLockConflictingLock from ResolveBlockConflicts

* Implement "quorum getrecsig" RPC

* Include decoded TX data in result of create_raw_tx

* Implement support for CLSIG in mininode.py

* Fix condition for update of nonLockedTxs.pindexMined

* Only add entries to nonLockedTxsByInputs when AddNonLockedTx is called for the first time

* Implement support for ISLOCK in mininode.py

* Implement tests for ChainLock vs InstantSend lock conflict resolution

* Handle review comment

The pull-tester folder contains a script to call multiple tests from the rpc-tests folder.

Every pull request to the Dash Core repository is built and run through the regression test suite. You can also run all or only individual tests locally.

Test dependencies

Before running the tests, the following must be installed.

Unix

The python3-zmq library is required. On Ubuntu or Debian it can be installed via:

sudo apt-get install python3-zmq

OS X

pip3 install pyzmq

Running tests

You can run any single test by calling

qa/pull-tester/rpc-tests.py <testname>

Or you can run any combination of tests by calling

qa/pull-tester/rpc-tests.py <testname1> <testname2> <testname3> ...

Run the regression test suite with

qa/pull-tester/rpc-tests.py

Run all possible tests with

qa/pull-tester/rpc-tests.py --extended

By default, tests will be run in parallel. To specify how many jobs to run, append --jobs=n (default n=4).

If you want to create a basic coverage report for the RPC test suite, append --coverage.

Possible options, which apply to each individual test run:

  -h, --help            show this help message and exit
  --nocleanup           Leave dashds and test.* datadir on exit or error
  --noshutdown          Don't stop dashds after the test execution
  --srcdir=SRCDIR       Source directory containing dashd/dash-cli
                        (default: ../../src)
  --tmpdir=TMPDIR       Root directory for datadirs
  --tracerpc            Print out all RPC calls as they are made
  --coveragedir=COVERAGEDIR
                        Write tested RPC commands into this directory

If you set the environment variable PYTHON_DEBUG=1 you will get some debug output (example: PYTHON_DEBUG=1 qa/pull-tester/rpc-tests.py wallet).

A 200-block -regtest blockchain and wallets for four nodes is created the first time a regression test is run and is stored in the cache/ directory. Each node has 25 mature blocks (25*500=12500 DASH) in its wallet.

After the first run, the cache/ blockchain and wallets are copied into a temporary directory and used as the initial test state.

If you get into a bad state, you should be able to recover with:

rm -rf cache
killall dashd

Writing tests

You are encouraged to write tests for new or existing features. Further information about the test framework and individual RPC tests is found in qa/rpc-tests.
