2022-08-04[doc] remove non-signaling mentions of BIP125glozow
Our RBF policy is different from the rules specified in BIP125. For example, the BIP does not mention Rule 6, and our Rule 4 uses the (configurable) incremental relay feerate (distinct from the minimum relay feerate). Those interested in our policy should refer to doc/policy/mempool-replacements.md instead. These rules may also continue to diverge with package RBF and other RBF improvements. Keep references to the BIP125 signaling wrt sequence numbers, since that is still correct and widely used. It is helpful to refer to this as "BIP125 signaling" since it is unambiguous and succint, especially if we have multiple ways to signal replaceability in the future. The rule numbers in doc/policy/mempool-replacements.md correspond largely to those of BIP 125, so we can still refer to them like "Rule 5."

4c9666bd73645b94ae81be1faf7a0b8237dd6e99 Mention `mempoolfullrbf` in policy/mempool-replacements.md (Antoine Riard) aae66ab43d794bdfaa2dade91760cc55861c9693 Update getmempoolinfo RPC with `mempoolfullrbf` (Antoine Riard) 3e27e317270fdc2dd02794fea9da016387699636 Introduce `mempoolfullrbf` node setting. (Antoine Riard) Pull request description: This is ready for review. Recent discussions among LN devs have brought back on the surface concerns about the security of multi-party funded transactions against pinnings attacks and other mempool-based nuisances. The lack of full-rbf transaction-relay topology connected to miners open the way to cheap and naive DoS against multi-party funded transactions (e.g coinjoins, dual-funded channels, on-chain DLCs, ...) without solutions introducing an overhead cost or centralization vectors afaik . For more details, see [0]. This PR implements a simple `fullrbf` setting, where the node always allows transaction replacement, ignoring BIP125 opt-in flag. The default value of the setting stays **false**, therefore opt-in replacement is still the default Bitcoin Core replacement policy. Contrary to a previous proposal of mine and listening to feedbacks collected since then [1], I think this new setting simply offers more flexibility in a node transaction-relay policy suiting one's application requirements, without arguing a change of the default behavior. I [posted](https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-June/020557.html) on the ML to invite operators with a bitcoin application sensitive to full-rbf (e.g dual-funded LN channels service providers) or mempool researchers to join a bootstrapped full-rbf activated peers network for experimentation and learning. If people have strong opinions against the existence of such full-rbf transaction-relay network, I'm proposing to express them on the future thread.

2022-07-06Introduce `mempoolfullrbf` node setting.Antoine Riard
This new node policy setting enables to accept replaced-by-fee transaction without inspection of the replaceability signaling as described in BIP125 "explicit signaling". If turns on, the node mempool accepts transaction replacement as described in `policy/mempool-replacements.md`. The default setting value is `false`, implying opt-in RBF is enforced.

2022-01-11test: MiniWallet: support default `from_node` for creating txsSebastian Falbesoner
If no `from_node` parameter is passed explicitely to the `create_self_transfer` method, the test node passed in the course of creating the MiniWallet instance is used. This seems to be the main use-case in most of the current functional tests, i.e. in many instances the calls can be shortened.

2021-12-08test: feature_rbf.py: check specified wallet type availabilitySebastian Falbesoner
The test currently leads to a failure if in general wallet support is compiled, but the library for the specified type (BDB/SQLite) is not, i.e. if started with the `--legacy-wallet` parameter, but bitcoind is compiled without BDB support. Fix this by checking if the specified wallet type (BDB for legacy wallet, SQLite for descriptor wallet) is available. Also move the helper `is_specified_wallet_compiled()` to the test framework's class BitcoinTestFramework first, so it can be reused.

In order to do that, the amounts for the utxos have to be scaled down in two sub-tests first (`test_doublespend_chain` and `test_doublespend_tree`, see first two commits), since we need amounts passed to `make_utxo` than can be funded by only one input. For creating UTXOs with a value of 50 BTC, we'd need to implement a method for consolidating multiple utxos into one first, which seems to be overkill. Note that after this PR's change, there is only one sub-test left (`test_rpc`) that needs the wallet compiled into bitcoind.

2019-10-14test: fix "tx-size-small" errors after default address changeSebastian Falbesoner
Addresses #17043, affects RBF and BIP68 functional tests. The "tx-size-small" policy rule rejects transactions with a non-witness size of smaller than 82 bytes (see src/validation.cpp:MemPoolAccept::PreChecks(...)), which corresponds to a transaction with 1 segwit input and 1 P2WPKH output. Through the default address change, the created test transactions have segwit inputs now and sending to short scriptPubKeys might violate this rule. By bumping the dummy scriptPubKey size to 22 bytes (= the size of a P2WPKH scriptPubKey), on all occurences the problem is solved. The dummy scriptPubKey has the format: 21 <21-byte-long string of 'a' or 1s> former commit messages, now squashed: test: rbf, bip68: use constant DUMMY_P2WPKH_SCRIPT for bumped scriptPubKey test: rbf, bip68: use constant DUMMY_P2WPKH_SCRIPT for dummy scriptPubKeys (b'a' * 35) test: rbf, bip68: comment DUMMY_P2WPKH_SCRIPT constant, put into common (new) module

At this point there is no reasonable excuse to disable opt-in RBF, and, unlike when this option was added, there are now significant issues created when disabling it (in the form of compact block reconstruction failures). Further, it breaks a lot of modern wallet behavior.
