Force network to be mixed into DbConfig rather than DbConfig to be mixed into the network * Add ammonite to db-commons, remove noisy logs * remove mixin for DbConfig that required a NetworkDb. Now networkDb is just a field on 'DbConfig', this simplifies things downstream type wise when interacting with the projects AppConfig. This commit also removes a parameter from AppConfig, now only a DbConfig needs to be passed in, and we can derive the network and chain params from the DbConfig. The only exemption is UnitTestDbConfig as it is sometimes handy to specify a different network (i.e. mainnet) when testing * Turn DbConfig objects to case objects, wrap those case objects in their parent type companion object * remove cast in Wallet.scala * Add EnhancedEither class for 2.11 compat (#437) Add implicit conversion from Either to 2.11-compatible Either-wrapper. Also remove trailing comma in WalletTestUtil that breaks 2.11 build. * Fix CI tests hanging (#438) * Execute wallet tests sequentially to avoid SQLite deadlocks * Refactor logback config to reduce duplication * Use in-memory SQLite DB for unit tests * Debug prints for DatabaseConfig.forConfig * Fork JVMs in test to ensure proper in-memory DBs * Pass in Akka config to Eclair tests, avoid cluttering Akka log output * Don't fork JVM on node tests' * Move things out of ChainUnitTest (#448) * Move things out of ChainUnitTest * Remove printlns * 2019 04 29 client test (#449) * Bump timeout on connect to node test * Change from isConnected -> isInitialized to avoid the error trying to disconnect before we are fully initialized * Wrote tests for POW difficulty change calculation and header processing (#429) Fixed BitcoinPowTest Rebased onto AppConfig code Rewrote ChainHandler integration test Made chain handler test synchronous Fixed a couple test bugs Implmented a more efficient getAncestorByHeight Fixed ChainHandler integration test by using the correct starting conditions Responded to code review Responded to more code review Deleted redundant Pow test Made BlockHeaderDAO.getAncestorAtHeight use a List for its loop to improve performance * WIP: Create ChainSync, BitcoindChainHandlerViaRpc, add simple ChainSyncTes… (#450) * Create ChainSync, BitcoindChainHandlerViaRpc, add simple ChainSyncTest to sync one block from a external bitcoind instance via rpc * Add check for having the best block hash in our chain state already * Fix prev block hash to be empty hash if genesis block header * BlockchainBuilder (#439) * First commit for implementing a BlockchainBuilder * use Builder rather than ReusableBuilder to be compatible with scala 2.11.x * Decouple Blockchain & BlockHeaderDAO * Rebase onto node, incorporate changes in #429 * Add more comments * Reverse order of headers in builder * rebase onot node branch, refactor apis * DB: Add utility method for listing tables in a DB (#447) * Node rebase (#458) * Implement BIP32 path diffing * Rebase node onto newest HD changes in master * Fix 2.11 compile errors * 2019 05 01 wallet ammonite scripts pt2 (#452) * wip -- not finding testkit in doc worksheet Wip -- classdef not found for create-wallet.sc zmq bug Clean up some logs nest zmq start in bitcoindF update jeromq to 0.5.2-SNAPSHOT to get rid of annoying log to stdout Rebase onto node branch with new configs Successfully running ammonite script create-wallet.sc 2019 05 01 wallet ammonite scripts pt2 (#25) * Refactor Ammonite dep * Add basic error handling in AmmoniteBridge * Add very basic README for doc project Fix compile issues after rebasing onto master Add code to sync our wallet code with bitcoind after creating a tx * refactor ZMQSubscriber to _hopefully_ avoid hanging when we call context.term(). We do this by closing the socket before calling context.term() and using socket.setLinger() * Update doc/src/main/scala/org/bitcoins/doc/wallet/create-wallet.sc Co-Authored-By: Christewart <stewart.chris1234@gmail.com> * 2019 05 05 sync chain (#460) * Add code to sync our wallet code with bitcoind after creating a tx Add script to illustrate how the chain persisted and how to sync against a running bitcoind instance on regtest * fix bug relating to subtraction operator not being communative in Pow.getNextWorkRequired(). This kept us from being able to switch proof of work intervals correctly * rename script from persist-chain.sc -> sync-chain.sc * fix 2.11.x compile issues * Refactor chain, node, wallet config (#463) * Refactor chain, node, wallet config Get rid of NetworkDb, DbConfig Add proper structure to conf system, moving everything under the bitcoin-s root key. * Remove Scalacheck from node project * Add doc on configuration * Add override feature to AppConfig * Address code review in #463 * Throw if default data dir is used in tests, add Scaladoc to AppConfig * Add explanations for withOverrides, link to configuration.md from AppConfig * Fix compile error * Moves chain fixtures to testkit project (#475) reset node files * Store encrypted mnemonic to disk (#462) * Add WalletStorage object * Add encrypted mnemonic storage, locked wallet Add lock and unlock operations to wallet. Separate between locked and unlock wallet. * Handle non-existant seed file * Respond to code review from Chris * Use val instead of import * Add doc on how mnemonics are encrypted/stored * 2019 05 15 spv sync headers (#479) * Implement SpvNode skeleton, create NodeUnitTest and move it to the testkit * Implement test case to sync a header via spv into bitcoin-s * Fix compiler errors * Make node project Main runnable (#26) * Add logging configuration to node project * Make default config workable in non-test environments * Add more logging of config in BH DAO and AppConfig * Make Peer id optional * Make node Main.scala runnable * Implement Main.scala to sync with a locally running bitcoind instance. You can now run with 'bloop run node' and sync the node if you adjust the parameters inside of Main.scala. This also reworks the structure of 'AppConfig'. It turns the *AppConfig into a case class intead of case objects. This allows us to pass custom configs into those case classes * Address code review from torkel * Reintroduce withOverrides (#29) * Turn off chain validation logs * Make datadir a parameter to bitcoind config rather than having it implicitly written to the bitcoin.conf file. This was a difference that was occurring in the node branch which had a parameter for the datadir and master which was implicitly writing it to bitcoin.conf * Add ability to overrwrite conf file except in the case of overwriting the DEFAULT_DATADIR & DEFAULT_CONF * remove extra Bitcoind.stopServers in WalletIntegrationTest

### db-commons
This is a project that is meant to contain re-usable database related infrastructure for bitcoin-s. This project is a dependency of [`wallet`](../wallet/) and [`node`](../node).
The library that bitcoin-s currently uses for database related things is called [`Slick`](http://slick.lightbend.com/doc/3.3.0/).
The most important file in this project is [`DbConfig`](src/main/scala/org/bitcoins/db/DbConfig.scala). This provides a
common way for databases to be accessed from configuration files. For more information on how Slick configuration files
work please see this [reference](http://slick.lightbend.com/doc/3.3.0/gettingstarted.html#database-configuration).
This project expects the following keys for databases
- mainnetDb
- testnet3Db
- regtestDb
- unittestDb
This will be read by [`DbConfig`](src/main/scala/org/bitcoins/db/DbConfig.scala) to specify database information related
to a specific project. You can look at the database configuration for the [`node`](../node/src/main/resources/application.conf) project for an example
of how this works.
