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
