1abcecc40c518a98b7d17880657ec0247abdf125 Tests: Use self.chain instead of 'regtest' in almost all current tests (Jorge Timón) Pull request description: Simply avoiding the hardcoded string in more places for consistency. It can also allow for more easily reusing tests for other chains other than regtest. Separated from #8994 . Continues #16509 . It is still not complete (ie to be complete, we need the -chain parameter in #16680 and make whether acceptnonstdtxs is allowed for that chain or not customizable for regtest [or for custom chains like in #8994 ] ). But while being incomplete like #16509 , it's quite simple to review and another step forward IMO. ACKs for top commit: Sjors: re-ACK 1abcecc. I think it's an improvement even if incomplete and if some PR's might accidentally bring "regtest" back. Subsequent improvements hopefully don't have to touch 16 files. elichai: Code review ACK 1abcecc40c518a98b7d17880657ec0247abdf125 ryanofsky: Code review ACK 1abcecc40c518a98b7d17880657ec0247abdf125. ryanofsky: Code review ACK 1abcecc40c518a98b7d17880657ec0247abdf125 Tree-SHA512: 5620de6dab235ca8bd8670d6366c7b9f04f0e3ca9c5e7f87765b38e16ed80c17d7d1630c0d5fd7c5526f070830d94dc74cc2096d8ede87dc7180ed20569509ee

"""Test tx status in case of reorgs while wallet being shutdown.
|
|
|
|
Wallet txn status rely on block connection/disconnection for its
|
|
accuracy. In case of reorgs happening while wallet being shutdown
|
|
block updates are not going to be received. At wallet loading, we
|
|
check against chain if confirmed txn are still in chain and change
|
|
their status if block in which they have been included has been
|
|
disconnected.
