6d1f51343c [rpc] fundrawtransaction, walletcreatefundedpsbt lock manually selected coins (Sjors Provoost)
Pull request description:
When using `fundrawtransaction` and `walletcreatefundedpsbt` with `lockUnspents`, it would only lock automatically selected coins, not manually selected coins. That doesn't make much sense to me if the goal is to prevent accidentally double-spending yourself before you broadcast a transaction.
Note that when creating a transaction, manually selected coins are automatic "unlocked" (or more accurately: the lock is ignored). Earlier versions of this PR introduced an error when a locked coin is manually selected, but this idea was abandoned after some discussion. An application that uses this RPC should either rely on automatic coin selection (with `lockUnspents`) or handle lock concurrency itself with manual coin selection. In particular it needs to make sure to avoid/pause calls with automatic coin selection between calling `lockunspent` and the subsequent spending RPC.
See #7518 for historical background.

d841301010 test: Add docstring to wait_until() in util.py to warn about its usage (Seleme Topuz)
1343c86c7c test: Update wait_until usage in tests not to use the one from utils (Seleme Topuz)
Pull request description:
Replace global (from [test_framework/util.py](https://github.com/bitcoin/bitcoin/blob/master/test/functional/test_framework/util.py#L228)) `wait_until()` usages with the ones provided by `BitcoinTestFramework` and `P2PInterface` classes.
The motivation behind this change is that the `util.wait_until()` expects a timeout, timeout_factor and lock and it is not aware of the context of the test framework. `BitcoinTestFramework` offers a `wait_until()` which has an understandable amount of default `timeout` and a shared `timeout_factor`. Moreover, on top of these, `mininode.wait_until()` also has a shared lock.

9e2897d020 scripted-diff: Rename mininode_lock to p2p_lock (John Newbery)
Pull request description:
New contributors are often confused by the terminology in the test framework, and what the difference between a _node_ and a _peer_ is. To summarize:
- a 'node' is a bitcoind instance. This is the thing whose behavior is being tested. Each bitcoind node is managed by a python `TestNode` object which is used to start/stop the node, manage the node's data directory, read state about the node (eg process status, log file), and interact with the node over different interfaces.
- one of the interfaces that we can use to interact with the node is the p2p interface. Each connection to a node using this interface is managed by a python `P2PInterface` or derived object (which is owned by the `TestNode` object). We can open zero, one or many p2p connections to each bitcoind node. The node sees these connections as 'peers'.
For historic reasons, the word 'mininode' has been used to refer to those p2p interface objects that we use to connect to the bitcoind node (the code was originally taken from the 'mini-node' branch of https://github.com/jgarzik/pynode/tree/mini-node). However that name has proved to be confusing for new contributors, so rename the remaining references.

02fbe3ae0b net: add nLastBlockTime/TXTime to CNodeStats, CNode::copyStats (Jon Atack)
Pull request description:
This PR adds inbound peer eviction criteria `nLastBlockTime` and `nLastTXTime` to `CNodeStats` and `CNode::copyStats`, which then allows exposing them in the next commit as `last_transaction` and `last_block` Unix Epoch Time fields in RPC `getpeerinfo`.
This may be useful for writing missing eviction tests. I'd also like to add `lasttx` and `lastblk` columns to the `-netinfo` dashboard as described in https://github.com/bitcoin/bitcoin/pull/19643#issuecomment-671093420.

<jonatack> i'm running bitcoin locally with nLastBlockTime and nLastTXTime added to getpeerinfo for my peer connections dashboard
<jonatack> sipa: is there a good reason why that (eviction criteria) data is not exposed through getpeerinfo currently?

As I was playing with indices a I was missing an RPC that gives information about the active indices in the node. I think this can be helpful for many users, especially since there are some new index candidates coming up (#14053, #18000) that can give a quick overview without the user having to parse the logs.
Feature summary:
- Adds new RPC `listindices` (placed in Util section)
- That RPC only lists the actively running indices
- For each index it gives the name, whether it is synced and up to which block height it is synced

7f13dfb587 test: test the implicit avoid partial spends functionality (Karl-Johan Alm)
b82067bf69 wallet: try -avoidpartialspends mode and use its result if fees are below threshold (Karl-Johan Alm)
Pull request description:
The `-avoidpartialspends` feature is normally disabled, as it may affect the optimal fee for payments. This PR introduces a new parameter `-maxapsfee` (max avoid partial spends fee) which acts on the following values:
* -1: disable partial spend avoidance completely (do not even try it)
* 0: only do partial spend avoidance if fees are the same or better as the regular coin selection
* 1..∞: use APS variant if the absolute fee difference is less than or equal to the max APS fee
For values other than -1, the code will now try partial spend avoidance once, and if that gives a value within the accepted range, it will use that.
Example: -maxapsfee=0.00001000 means the wallet will do regular coin select, APS coin select, and then pick AKS iff the absolute fee difference is <= 1000 satoshi.
Edit: updated this to reflect the fact we are now using a max fee.

Pull request description:
This PR gives some love to the functional test `p2p_feefilter.py` by introducing the following changes:
* add missing log messages for the `test_feefilter` subtest (the main one)
* deduplicate code by using the utility function `wait_until` (already using the [recently introduced version](12410b1feb)) instead of a manual condition checking loop with `time.sleep`
* improve naming of the function `matchAllInvs` (more expressive name, snake_case) and moving it from global namespace to the connection class `FeefilterConn`
* speeding up the test significantly by the good ol' method of activating immediate tx relay (as seen on e.g. https://github.com/bitcoin/bitcoin/pull/17121, https://github.com/bitcoin/bitcoin/pull/17124, https://github.com/bitcoin/bitcoin/pull/17340, https://github.com/bitcoin/bitcoin/pull/17362, ...):

A rebase of #13084 which additionally modifies the test code (unaddressed in the original, assuming sipa is too busy to deal with this at the moment).
Relatively simple bugfix so it'd be good to have merged soon.
Turning OP_1NEGATE into 0x0181 results in a larger-than-necessary data push instead of just actually using the OP_1NEGATE opcode (0x4f). This fails the minimal push rule of BIP 62 and makes the result non-standard.

fa89ca9b5b refactor: Use C++11 range based for loops to simplify rpc code (MarcoFalke)
fa459bdc87 rpc: Treat all args after a hidden arg as hidden as well (MarcoFalke)
Pull request description:
This is split out from #18531 to just touch the RPC methods in misc. Description from the main pr:
### Motivation
RPCArg names in the rpc help are currently only used for documentation. However, in the future they could be used to teach the server the named arguments. Named arguments are currently registered by the `CRPCCommand`s and duplicate the RPCArg names from the documentation. This redundancy is fragile, and has lead to errors in the past (despite having linters to catch those kind of errors). See section "bugs found" for a list of bugs that have been found as a result of the changes here.
### Changes
The changes here add an assert in the `CRPCCommand` constructor that the RPCArg names are identical to the ones in the `CRPCCommand`.
### Future work
> Here or follow up, makes sense to also assert type of returned UniValue?
Sure, but let's not get ahead of ourselves. I am going to submit any further works as follow-ups, including:
* Removing the CRPCCommand arguments, now that they are asserted to be equal and thus redundant
* Removing all python regex linters on the args, now that RPCMan can be used to generate any output, including the cli.cpp table
* Auto-formatting and sanity checking the RPCExamples with RPCMan
* Checking passed-in json in self-check. Removing redundant checks
* Checking returned json against documentation to avoid regressions or false documentation
* Compile the RPC documentation at compile-time to ensure it doesn't change at runtime and is completely static
### Bugs found
* The assert identified issue #18607
* The changes itself fixed bug #19250

c133cdcdc3 Cap listsinceblock target_confirmations param (Adam Stein)
Pull request description:
This addresses an issue brought up in #19587.
Currently, the `target_confirmations` parameter to `listsinceblock` is not checked for being too large. When `target_confirmations` is greater than one more than the current number of blocks, `listsinceblock` fails with error code -1. In comparison, when `target_confirmations` is less than 1, a -8 "Invalid parameter" error code is thrown.
This PR fixes the issue by returning a -8 "Invalid parameter" error if the `target_confirmations` value corresponds to a block with more confirmations than the genesis block. This happens if `target_confirmations` exceeds one more than the number of blocks.

Previously, listsinceblock would fail with error code -1 when the
target_confirmations exceeded the number of confirmations of the genesis
block. This commit allows target_confirmations to refer to a lastblock
hash with more confirmations than exist in the chain by setting the
lastblock hash to the genesis hash in this case. This allows for
`listsinceblock "" 6` to not fail if the block count is less than 5
which may happen on regtest.
Includes update to the functional test for listsinceblock to test for
this case.
Most of the test time is spent in wait_for_invs() after sending to addresses,
i.e. the bottleneck is in relaying transactions. By whitelisting the peers via
-whitelist, the inventory is transmissioned immediately rather than on average
every 5 seconds, speeding up the test significantly:

37a480e0cd [net] Add addpeeraddress RPC method (John Newbery)
ae8051bbd8 [test] Test that getnodeaddresses() can return all known addresses (John Newbery)
f26502e9fc [addrman] Specify max addresses and pct when calling GetAddresses() (John Newbery)
Pull request description:
Currently addrman only allows a maximum of 1000 records or 23% of all records to be returned in a call to `GetAddr()`. Relax this limit and have the client specify the max records they want. For p2p, behaviour is unchanged (but the rate limiting is set inside net_processing, where it belongs). For RPC, `getnodeaddresses` can now return the complete addrman, which is helpful for testing and monitoring.
Also add a test-only RPC `addpeeraddress`, which adds an IP address:port to addrman. This is helpful for testing (eg #18991).

dac7a111bd refactor: test: use _ variable for unused loop counters (Sebastian Falbesoner)
Pull request description:
This tiny PR substitutes Python loops in the form of `for x in range(N): ...` by `for _ in range(N): ...` where applicable. The idea is indicating to the reader that a block (or statement, in list comprehensions) is just repeated N times, and that the loop counter is not used in the body, hence using the throwaway variable. This is already done quite often in the current tests (see e.g. `$ git grep "for _ in range("`). Another alternative would be using `itertools.repeat` (according to Python core developer Raymond Hettinger it's [even faster](https://twitter.com/raymondh/status/1144527183341375488)), but that doesn't seem to be widespread in use and I'm not sure about a readability increase.
The only drawback I see is that whenever one wants to debug loop iterations, one would need to introduce a loop variable again. Reviewing this is basically a no-brainer, since tests would fail immediately if a a substitution has taken place on a loop where the variable is used.
Instances to replace were found by `$ git grep "for.*in range("` and manually checked.

9f88ded82b test addition of unknown segwit spends to txid reject filter (Gregory Sanders)
7989901c7e Add txids with non-standard inputs to reject filter (Suhas Daftuar)
Pull request description:
Our policy checks for non-standard inputs depend only on the non-witness
portion of a transaction: we look up the scriptPubKey of the input being
spent from our UTXO set (which is covered by the input txid), and the p2sh
checks only rely on the scriptSig portion of the input.
Consequently it's safe to add txids of transactions that fail these checks to
the reject filter, as the witness is irrelevant to the failure. This is helpful
for any situation where we might request the transaction again via txid (either
from txid-relay peers, or if we might fetch the transaction via txid due to
parent-fetching of orphans).
Further, in preparation for future witness versions being deployed on the
network, ensure that WITNESS_UNKNOWN transactions are rejected in
AreInputsStandard(), so that transactions spending v1 (or greater) witness
outputs will fall into this category of having their txid added to the reject
filter.

Pull request description:
This is a very simple code change with a big p2p privacy benefit.
It’s currently trivial to scrape any reachable node’s AddrMan (a database of all nodes known to them along with the timestamps).
We do have a limit of one GETADDR per connection, but a spy can disconnect and reconnect even from the same IP, and send GETADDR again and again.
Since we respond with 1,000 random records at most, depending on the AddrMan size it takes probably up to 100 requests for an spy to make sure they scraped (almost) everything.
I even have a script for that. It is totally doable within couple minutes.
Then, with some extra protocol knowledge a spy can infer the direct peers of the victim, and other topological stuff.
I suggest to cache responses to GETADDR on a daily basis, so that an attacker gets at most 1,000 records per day, and can’t track the changes in real time. I will be following up with more improvements to addr relay privacy, but this one alone is a very effective. And simple!
I doubt any of the real software does *reconnect to get new addrs from a given peer*, so we shouldn’t be cutting anyone.
I also believe it doesn’t have any negative implications on the overall topology quality. And the records being “outdated” for at most a day doesn’t break any honest assumptions either.

Pull request description:
`BerkeleyBatch` and `BerkeleyDatabase` are kind of messy. The goal of this is to clean up them up so that they are logically separated.
`BerkeleyBatch` currently handles the creation of the `BerkeleyDatabase`'s `Db` handle. This is instead moved into `BerkeleyDatabase` and is called by `BerkeleyBatch`.
Instead of having `BerkeleyEnvironment` track each database's usage, have `BerkeleyDatabase` track this usage itself with the `m_refcount` variable that is present in `WalletDatabase`.
Lastly, instead of having each `BerkeleyEnvironment` store the fileids of the databases open in it, have a global `g_fileids` to track those fileids. We were already checking fileid uniqueness globally (by checking the fileids in every environment when opening a database) so it's cleaner to do this with a global variable.
All of these changes allow us to make `BerkeleyBatch` and `BerkeleyDatabase` no longer be friend classes.

Pull request description:
Using txids (a transaction's hash, without witness) for transaction relay is problematic, post-segwit -- if a peer gives us a segwit transaction that fails policy checks, it could be because the txid associated with the transaction is definitely unacceptable to our node (regardless of the witness), or it could be that the transaction was malleated and with a different witness, the txid could be accepted to our mempool.
We have a bloom filter of recently rejected transactions, whose purpose is to help us avoid redownloading and revalidating transactions that fail to be accepted, but because of this potential for witness malleability to interfere with relay of valid transactions, we do not use the filter for segwit transactions. This issue is discussed at some length in #8279. The effect of this is that whenever a segwit transaction that fails policy checks is relayed, a node would download that transaction from every peer announcing it, because it has no way presently to cache failure. Historically this hasn't been a big problem, but if/when policy for accepting segwit transactions were to change (eg taproot, or any other change), we could expect older nodes talking to newer nodes to be wasting bandwidth because of this.
As discussed in that issue, switching to wtxid-based relay solves this problem -- by using an identifier for a transaction that commits to all the data in our relay protocol, we can be certain if a transaction that a peer is announcing is one that we've already tried to process, or if it's something new. This PR introduces support for wtxid-based relay with peers that support it (and remains backwards compatible with peers that use txids for relay, of course).
Apart from code correctness, one issue to be aware of is that by downloading from old and new peers alike, we should expect there to be some bandwidth wasted, because sometimes we might download the same transaction via txid-relay as well as wtxid-relay. The last commit in this PR implements a heuristic I want to analyze, which is to just delay relay from txid-relay peers by 2 seconds, if we have at least 1 wtxid-based peer. I've just started running a couple nodes with this heuristic so I can measure how well it works, but I'm open to other ideas for minimizing that issue. In the long run, I think this will be essentially a non-issue, so I don't think it's too big a concern, we just need to bite the bullet and deal with it during upgrade.
Finally, this proposal would need a simple BIP describing the changes, which I haven't yet drafted. However, review and testing of this code in the interim would be welcome.
To do items:
- [x] Write BIP explaining the spec here (1 new p2p message for negotiating wtxid-based relay, along with a new INV type)
- [ ] Measure and evaluate a heuristic for minimizing how often a node downloads the same transaction twice, when connected to old and new nodes.

At Marco's suggestion, cherry-picked part of #19134 to nicely simplify using `wait_until`.

Using both txid and wtxid-based relay with peers means that we could sometimes
download the same transaction twice, if announced via two different hashes from
different peers.
Use a heuristic of delaying txid-peer-getdata requests by 2 seconds, if we have
at least one wtxid-based peer.
This adds a field to CNodeState that tracks whether to relay transactions with
that peer via wtxid, instead of txid. As of this commit the field will always
be false, but in a later commit we will add a way to negotiate turning this on
via p2p messages exchanged with the peer.

Pull request description:
This is a followup to #19204 which uses `minfeefilter=MAX_MONEY` to effectively shut off txrelay, thereby reducing inv traffic, when nodes are in IBD. It was [missing](https://github.com/bitcoin/bitcoin/pull/19204#issuecomment-644040070) a functional test.

970de70bdd Dump transaction version as an unsigned integer in RPC/TxToUniv (Matt Corallo)
Pull request description:
Consensus-wise we already treat it as an unsigned integer (the
only rules around it are in CSV/locktime handling), but changing
the underlying data type means touching consensus code for a
simple cleanup change, which isn't really worth it.
