This resurrects the regression test network that was removed before
initial launch although it really should not have been. The simulation
test network and the regression test network do not serve the same
purpose. Specifically, the regression test network is intended for unit
tests, RPC server tests, and consensus tests. On the other hand, the
simulation test network is intended for private use within a group of
individuals doing simulation testing and full integration tests between
different applications such as wallets, voting service providers, mining
pools, block explorers, and other services that build on Decred.
Keeping the concerns separate will allow the simulation test network to
be modified in ways such as activating consensus changes that have been
successfully voted into mainnet without also needing to vote them in on
the simulation test network while still preserving the ability for the
unit tests to properly test the voting semantics and handling to help
prevent regressions.
In addition to resurrecting the regression test network, this also fully
fleshes out new values for the various addresses prefixes (Rk, Rs, Re,
etc), HD key prefixes (rprv, rpub), and treasury multisig details.
As a part of resurrecting the network, a new CLI flag `--regnet` is
added to allow the RPC test harness connect to a running instance, the
areas of the code which involve votes have been modified to allow the
votes to apply to the new network, and tests have been added to the
relevant modules.
This bumps the affected module versions as follows:
- github.com/decred/dcrd/wire@v1.2.0
- github.com/decred/dcrd/chaincfg@v1.2.0
- github.com/decred/dcrd/dcrutil@v1.2.0
- github.com/decred/dcrd/hdkeychain@v1.1.1
The blockchain module is also affected, but since its version has
already been bumped since the last release tag, it is not bumped again.
Finally, this does not include switching unit tests or the RPC test
harness over the new network since that will be done in a separate
commit.
main: add address encoding magic constants test
Ensures address encoding magics and NetworkAddressPrefix are consistent
with each other. This test will light red when a new network is started
with incorrect values.
This adds a new testnet3 network with new genesis block, block one
ledger, treasury address, and network magic.
All consensus rules that were voted in by testnet2 are automatically
active on the new testnet3 without having to vote them in again.
Consequently, there are no consensus vote agendas defined for it.
