* Start the process of refactoring our ChainHandler to be able to avoid database calls on TipValidation
WIP: Begin explicity passing state back and forth in return types of PeerMessageReceiver, P2PClient, , DataMessageHandler. This commit also implements the ability to keep our blockchain completely in memory. Previously when we were updating the tip of the chain, we had to make a database read to figure out what the best tips are. This is suboptimal for performance because a database read needs to be done for every block header we see, now we just keep the chain in memory
Fix bug in DataMessageHandler that pre-emptively sent a getheadersmsg to our peer. Make 'chainApiF' internal to our spvNode (not a parameter). This forces the chainApi to be created from disk everytime a new SpvNode is spun up. This keeps us in sync with the blockchain at disk at the cost of disk access and less modularity of SpvNode
Address torkel code review
Fix rebase issues
Address code review
Address nadav code review
* Rebase onto master, fix api changes
* Address issue #673, also refactor fixture stuff to be in companion objects rather than traits so they can be re-used without extending the trait itself. This allows for more modularity with our fixtures
* fix bugs in unit tests, address #675 to make MerkleBufferTests faster
* Refactor test timeout in UpdateBloomFitlerTest
* fix callback logic bug on matching unrelated txs/addresses in UpdateBloomFilterTest, re-order broadcasting of things to avoid async bugs hopefully
* Make a def in NodeUnitTest, this keeps tests in the same suite from using the same config. This allows us to write multiple tests per suite, instead of just one. This also adds implicit parameters to our fixture constructors/destructors to properly create and destroy this config. The long term goal here also should be getting rid of config.initialize() we are calling everywhere as this is a anti-pattern, fixtures should take care of construction and destruction of things
* Broadcast tx earlier in test case for UpdateBloomFilterTest
* Rework NodeWithWalletTest to use the new fixtures we have in the node project, now use SpvNodeFundedWalletBitcoind
* Add functionality for updating SPV node bloom filter
* Add SPV node shutdown to exit hook
* Clean up traits/case classes
* Change fixture in WalletBloomTest
* Fix logging bug in TransactionProcessing
* Add MerkleBuffers
In this commit we add MerkleBuffers, which is an object
that lets us aggreagate merkleblocks with their corresponding
transactions before sending them out. This is global, mutable
state (bad!) but it's a working solution for now;
* Use TestAsyncUtil
* Add MerkleBuffers test
* Send getdata if receiving single header
* Change awaitSync to use block count
* Fix UpdateBloomFilterTest
* Add more logging of chain/headers validation
* Send getdata for all blocks
* Nits: Scaladocs, comments toString
* Add logging to data directory
In this commit we add the ability for the node, chain
and wallet projects (+ the server) to log to the users
data directory instead of whatever directory the
binaries was launched from. This is inherently a bit
more complicated than our previous setup, because
we need to read the user directory before we can create
loggers. As a result of this, some files/methods were
moved around, so the relevant app config could be
found in scope.
We also introduce several logging categories that can be
tuned individually through user configuration. These logggers
are exposed both as traits that give a field `logger`, or
as methods that return the required logger.
* Add datadir configuration to AppConfig
In this commit we add support for AppConfig to pick up
the data directory configuration file. We also add
a section to the contributing guide on how to tune
logging levels.
* Pass data directories explicitly for configuration
* This PR is attempting to remove the publishing errors when publish
locally many of which are incorrectly linked things in scaladocs which
there are some differences in formatting. Hopefully this removes alot
if not all of the "link not found for ..." warning messages that show
up.
* Implement missing branch on POW validation for testnet, implement BlockHeaderDAO.find
* implement second special case for if we are allowing min difficulty blocks, but are at a POW change interval. If we are at a POW change interval, we return that block
* Address code review
In this commit we move the error handling part of bitcoind responses
closer to the source of where they will happen, hopefully
giving better error messages.
* Add functionality for broadcasting TXs to node
In this commit we add functionality and tests
for broadcasting a TX from our node. To accomplish
this we introduce a table over broadcastable TXs
that's added to when the externally facing method
broadcastTransaction(tx) withing SpvNode is called.
We send out a inv message for the TX we just added,
and upon receiving a getdata message we search in
the previously mentioned table for entries where
the hashes match up.
* Broadcast TX from server to SPV node
* Perform assertions on the balance of bitcoind after sending a TX
* Remove typeclass from broadcast TX
* Refactor withFundedWalletAndBitcoind
* Match on BitcoindExecption instead of throwable
* Clean up broadcast functionality after code review
Due to how bloom filters work (they give false
positives) it's meaningless to assert on _not_
receiving a transaction from our peer. In most
cases we're not going to receive an irrelevant
TX, but if it happens we can't be sure if it's
because we did something wrong or because we
just hit a false positive.
In this commit we
1) Add the notion of address types in the wallet, and remove
the emphasis on account types. Users now just request
a segwit/nested-segwit/legacy address, and we take care
of querying for the correct account
2) Fix a bug where a wallet could only get addresses for
its default address type. This was a pretty minor bug,
where a few values that should have been dynamic was
hard coded.
* Cleanup
In this commit we cleanup a few Scaladocs and change some
trait/impl pairs into just a case class.
* Node cleanup
In this commit we
1) Rename Client to P2PClient. Client is a very generic name.
2) Clean up some Scaladocs
3) Remove some unecessary objects/traits/classes and replace them
with case classes
4) Add trace logging of bytes received in P2PClient
