"""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 |
