"""Test activation of the first version bits soft fork.
"""Test CSV soft fork activation.
This soft fork will activate the following BIPS:
BIP 68 - nSequence relative lock times
BIP 112 - CHECKSEQUENCEVERIFY
BIP 113 - MedianTimePast semantics for nLockTime
regtest lock-in with 108/144 block signalling
activation after a further 144 blocks
mine 82 blocks whose coinbases will be used to generate inputs for our tests
mine 61 blocks to transition from DEFINED to STARTED
mine 144 blocks only 100 of which are signaling readiness in order to fail to change state this period
mine 144 blocks with 108 signaling and verify STARTED->LOCKED_IN
mine 140 blocks and seed block chain with the 82 inputs will use for our tests at height 572
mine 3 blocks and verify still at LOCKED_IN and test that enforcement has not triggered
mine 1 block and test that enforcement has triggered (which triggers ACTIVE)
mine 345 blocks and seed block chain with the 82 inputs will use for our tests at height 427
mine 2 blocks and verify soft fork not yet activated
mine 1 block and test that soft fork is activated (rules enforced for next block)
Test BIP 113 is enforced
Mine 4 blocks so next height is 580 and test BIP 68 is enforced for time and height
Mine 1 block so next height is 581 and test BIP 68 now passes time but not height
