This commit adds set of BIP0009 (Version Bits) deployment parameters
for all networks detailing the activation parameters for the segwit
soft-fork.
Additionally, the BIP0009 integration test has been updated to test for
the proper transitioning of version bits state for the segwit soft
fork. Finally, the `getblockchaininfo` test has also been updated to
properly display the state of segwit.
The github markdown interpreter has been changed such that it no longer
allows spaces in between the brackets and parenthesis of links and now
requires a newline in between anchors and other formatting. This
updates all of the markdown files accordingly.
While here, it also corrects a couple of inconsistencies in some of the
README.md files.
This adds tests which exercise the BIP0009 state transitions using the
newly available soft fork status information in the getblockchaininfo
RPC.
The following is an overview of the tests added:
- Assert the chain height is 0 and the state is ThresholdDefined
- Generate 1 fewer blocks than needed to reach the first state
transition
- Assert chain height is expected and state is still ThresholdDefined
- Generate 1 more block to reach the first state transition
- Assert chain height is expected and state moved to ThresholdStarted
- Generate enough blocks to reach the next state transition window, but
only signal support in 1 fewer than the required number to achieve
ThresholdLockedIn
- Assert chain height is expected and state is still ThresholdStarted
- Generate enough blocks to reach the next state transition window with
only the exact number of blocks required to achieve locked in status
signalling support
- Assert chain height is expected and state moved to ThresholdLockedIn
- Generate 1 fewer blocks than needed to reach the next state transition
- Assert chain height is expected and state is still ThresholdLockedIn
- Generate 1 more block to reach the next state transition
- Assert chain height is expected and state moved to ThresholdActive
In addition, it updates the existing BIP0009 mining tests to include
extra assertions that the chain height is at the expected height in
addition to checking that the bits are correctly set according to the
expected state.
This introduces a new package to house tests which use the rpctest
package to programmatically drive end-to-end integration testing and
move the existing RPC integration tests into the new package.
