Add RPC test for BIP 68/112/113 soft fork.
This RPC test will test both the activation mechanism of the first versionbits soft fork as well as testing many code branches of the consensus logic for BIP's 68, 112, and 113.

|

This test is meant to exercise activation of the first version bits soft fork
|
||||
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)
|
||||
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
|
||||
Mine 1 block so next height is 582 and test BIP 68 now passes time and height
|
||||
Test that BIP 112 is enforced
|
||||
|
||||
Various transactions will be used to test that the BIPs rules are not enforced before the soft fork activates
|
||||
And that after the soft fork activates transactions pass and fail as they should according to the rules.
|
||||
For each BIP, transactions of versions 1 and 2 will be tested.
|
||||
----------------
|
||||
BIP 113:
|
||||
bip113tx - modify the nLocktime variable
|
||||
|
||||
BIP 68:
|
||||
bip68txs - 16 txs with nSequence relative locktime of 10 with various bits set as per the relative_locktimes below
|
||||
|
||||
BIP 112:
|
||||
bip112txs_vary_nSequence - 16 txs with nSequence relative_locktimes of 10 evaluated against 10 OP_CSV OP_DROP
|
||||
bip112txs_vary_nSequence_9 - 16 txs with nSequence relative_locktimes of 9 evaluated against 10 OP_CSV OP_DROP
|
||||
bip112txs_vary_OP_CSV - 16 txs with nSequence = 10 evaluated against varying {relative_locktimes of 10} OP_CSV OP_DROP
|
||||
bip112txs_vary_OP_CSV_9 - 16 txs with nSequence = 9 evaluated against varying {relative_locktimes of 10} OP_CSV OP_DROP
|
||||
bip112tx_special - test negative argument to OP_CSV
