This updates all code in the main module to use the latest major modules
versions to pull in the latest updates.
A more general high level overview of the changes is provided below,
however, there is one semantic change worth calling out independently.
The verifymessage RPC will now return an error when provided with
an address that is not for the current active network and the RPC server
version has been bumped accordingly.
Previously, it would return false which indicated the signature is
invalid, even when the provided signature was actually valid for the
other network. Said behavior was not really incorrect since the
address, signature, and message combination is in fact invalid for the
current active network, however, that result could be somewhat
misleading since a false result could easily be interpreted to mean the
signature is actually invalid altogether which is distinct from the case
of the address being for a different network. Therefore, it is
preferable to explicitly return an error in the case of an address on
the wrong network to cleanly separate these cases.
The following is a high level overview of the changes:
- Replace all calls to removed blockchain merkle root, pow, subsidy, and
coinbase funcs with their standalone module equivalents
- Introduce a new local func named calcTxTreeMerkleRoot that accepts
dcrutil.Tx as before and defers to the new standalone func
- Update block locator handling to match the new signature required by
the peer/v2 module
- Introduce a new local func named chainBlockLocatorToHashes which
performs the necessary conversion
- Update all references to old v1 chaincfg params global instances to
use the new v2 functions
- Modify all cases that parse addresses to provide the now required
current network params
- Include address params with the wsClientFilter
- Replace removed v1 chaincfg constants with local constants
- Create subsidy cache during server init and pass it to the relevant
subsystems
- blockManagerConfig
- BlkTmplGenerator
- rpcServer
- VotingWallet
- Update mining code that creates the block one coinbase transaction to
create the output scripts as defined in the v2 params
- Replace old v2 dcrjson constant references with new types module
- Fix various comment typos
- Update fees module to use the latest major module versions and bump it v2

// Package chaincfg defines chain configuration parameters.
|
|
//
|
|
// In addition to the main Decred network, which is intended for the transfer
|
|
// of monetary value, there also exists two currently active standard networks:
|
|
// regression test and testnet (version 0). These networks are incompatible
|
|
// with each other (each sharing a different genesis block) and software should
|
|
// handle errors where input intended for one network is used on an application
|
|
// instance running on a different network.
|
|
//
|
|
// For library packages, chaincfg provides the ability to lookup chain
|
|
// parameters and encoding magics when passed a *Params. Older APIs not updated
|
|
// to the new convention of passing a *Params may lookup the parameters for a
|
|
// wire.DecredNet using ParamsForNet, but be aware that this usage is
|
|
// deprecated and will be removed from chaincfg in the future.
|
|
//
|
|
// For main packages, a (typically global) var may be assigned the address of
|
|
// one of the standard Param vars for use as the application's "active" network.
|
|
// When a network parameter is needed, it may then be looked up through this
|
|
// variable (either directly, or hidden in a library call).
|
|
//
|
|
// package main

|

// import (

// "fmt"
|

// "log"

|
|
// "github.com/decred/dcrd/dcrutil/v2"
|
|
// "github.com/decred/dcrd/chaincfg/v2"
|
|
// )
|
|
//
|
|
// var testnet = flag.Bool("testnet", false, "operate on the testnet Decred network")
|
|
//
|

// // By default (without -testnet), use mainnet.

// addr, err := dcrutil.NewAddressPubKeyHash(pubKeyHash, chainParams)
|

// log.Fatal(err)
|
|
// }

// fmt.Println(addr)
|
|
// }
|
|
//
|
|
// If an application does not use one of the standard Decred networks, a new
|
|
// Params struct may be created which defines the parameters for the
|
|
// non-standard network. As a general rule of thumb, all network parameters
|
|
// should be unique to the network, but parameter collisions can still occur.
