Pull request description:
All softforks that are active at the tip of mainnet, should also be active from genesis in regtest. Otherwise their rules might not be enforced in user testing, thus making their testing less useful.
To still allow tests to check pre-softfork rules, a runtime argument can change the activation height.

"""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
|
|
|
|
mine 83 blocks whose coinbases will be used to generate inputs for our tests
|
|
mine 344 blocks and seed block chain with the 83 inputs used 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
|
|
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
|
|
bip112tx_emptystack - test empty stack (= no argument) OP_CSV
