0000a0c7e9 Remove confusing and almost useless "unexpected version" warning (MarcoFalke)
Pull request description:
It is useless because it isn't displayed for most users:
* It isn't displayed in normal operation (because the validation debug category is disabled by default)
* It isn't displayed for users that sync up their nodes intermittently, e.g. once a day or once a week (because it is disabled for IBD)
* It is only displayed in the debug log (as opposed to the versionbits warning, which is displayed more prominently)
It is confusing because it doesn't have a use case:
Despite the above, if a user *did* see the warning, it would most likely be a false positive (like it has been in the past). Even if it wasn't, there is nothing they can do about it. The only thing they could do is to check for updates and hope that a fixed version is available. But why would the user be so scrupulously precise in enabling the warning and reading the log, but then fail to regularly check update channels for updated software?

0bfce9dc46 [addrman] Fix Connected() comment (John Newbery)
eefe194718 [net] Consolidate logic around calling CAddrMan::Connected() (John Newbery)
Pull request description:
Currently, the logic around whether we called CAddrMan::Connected() for
a peer is spread between verack processing (where we discard inbound
peers) and FinalizeNode (where we discard misbehaving and
block-relay-only peers). Consolidate that logic to a single place.
Also remove the CNode.fCurrentlyConnected bool, which is now
redundant. We can rely on CNode.fSuccessfullyConnected, since the two
bools were only ever flipped to true in the same place.

### 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 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

7486e2771e Tests: Unit test related to WalletDB ReadKeyValue (Bushstar)
32def8d1c2 Catch ios_base::failure specifically (Peter Bushnell)
Pull request description:
In https://github.com/bitcoin/bitcoin/pull/2950 a hash of the pubkey and private was added to speed up key import, this was made backwards compatible by reading the hash in a try block with an ellipses catch all in case the hash was not present.
CDataStream::read() specifically throws std::ios_base::failure, backwards compatibility expects only that error to be thrown, if something else gets thrown we should not be catching it. The change in this commit is to catch that exception only. If any other exception is thrown other than std::ios_base::failure it will be caught by the wider try block and an error written to the log and/or console.
CDataStream::read() throwing std::ios_base::failure.

fa7eed5be7 doc: Clarify that vpindexToConnect is in reverse order (MarcoFalke)
fa62304c97 Remove dead CheckForkWarningConditionsOnNewFork (MarcoFalke)
Pull request description:
The function has several code and logic bugs, which prevent it from working at all:
* `vpindexToConnect.back()` is passed to `CheckForkWarningConditionsOnNewFork`, which is the earliest connected block (least work block), *not* the new fork tip
* `ActivateBestChainStep` will never try to connect a block that descends from an invalid block, so the invalid fork will only ever be of height 1, never hitting the 7 block minimum condition
Instead of dragging the dead and wrong code around through every change in validation, remove it. In the future it could make sense to add a fork detection somewhere outside of the `ActivateBestChainStep` logic (maybe net_processing).

- allow non-actionable conf_target value of `0` and estimate_mode value of `""` to be passed to use `fee_rate` as a positional argument, in addition to as a named argument
- fix a bug in the experimental send RPC described in https://github.com/bitcoin/bitcoin/pull/20220#discussion_r513789526 where args were not being passed correctly into the options values
- update the feerate error message units for these RPCs from BTC/kB to sat/vB
- update the test coverage, help docs, doxygen docs, and some of the RPC examples
- other changes to address the excellent review feedback

It's lightly inspired by #77. It would be better if those changes made it into the upcoming release, but this PR is a good start imo.
* wallet encryption is no longer checked by default, because such a change in the default needs a separate discussion (fwiw, I suspect it increases the number of users losing access to coins)
* watch-only and descriptor wallet stuff is moved to advanced, so new users know they can safely ignore these check boxes
* bonus: when you click on "disable private keys" it disables encrypt wallet and checks blank wallet
* label changes: see screenshot
* tooltip changes: see code diff
Note that a blank wallet name isn't allowed in the dialog; I haven't addressed that.

842ae3842d wallet: Add utility method for CanSupportFeature (Andrew Chow)
Pull request description:
This PR cleans up the wallet upgrade mechanism a bit, fixes some probably bugs, and adds more test cases.
The `nWalletMaxVersion` member variable has been removed as it made `CanSupportFeature` unintuitive and was causing a couple of bugs. The reason this was introduced originally was to allow a wallet upgrade to only occur when the new feature is first used. While this makes sense for the old `-upgradewallet` option, for an RPC, this does not quite make sense. It's more intuitive for an upgrade to occur if possible if the `upgradewallet` RPC is used as that's an explicit request to upgrade a particular wallet to a newer version. `nWalletMaxVersion` was only relevant for upgrades to `FEATURE_WALLETCRYPT` and `FEATURE_COMPRPUBKEY` both of which are incredibly old features. So for such wallets, the behavior of `upgradewallet` will be that the feature is enabled immediately without the wallet needing to be encrypted at that time (note that `FEATURE_WALLETCRYPT` indicates support for encryption, not that the wallet is encrypted) or for a new key to be generated.
`CanSupportFeature` would previously indicate whether we could upgrade to `nWalletMaxVersion` not just whether the current wallet version supported a feature. While this property was being used to determine whether we should upgrade to HD and HD chain split, it was also causing a few bugs. Determining whether we should upgrade to HD or HD chain split is resolved by passing into `ScriptPubKeyMan::Upgrade` the version we are upgrading to and checking against that. By removing `nWalletMaxVersion` we also fix a bug where you could upgrade to HD chain split without the pre-split keypool.
`nWalletMaxVersion` was also the version that was being reported by `getwalletinfo` which meant that the version reported was not always consistent across restarts as it depended on whether `upgradewallet` was used. Additionally to make the wallet versions consistent with actually supported versions, instead of just setting the wallet version to whatever is given to `upgradewallet`, we normalize the version number to the closest supported version number. For example, if given 150000, we would store and report 139900.
Another bug where CHDChain was not being upgraded to the version supporting HD chain split is also fixed by this PR.
Lastly several more tests have been added. Some refactoring to the test was made to make these tests easier. These tests check specific upgrading scenarios, such as from non-HD (version 60000) to HD to pre-split keypool. Although not specifically related to `upgradewallet`, `UpgradeKeyMetadata` is now being tested too.
Part of the new tests is checking that the wallet files are identical before and after failed upgrades. To facilitate this, a utility function `sha256sum_file` has been added. Another part of the tests is to examine the wallet file itself to ensure that the records in the wallet.dat file have been correctly modified. So a new `bdb.py` module has been added to deserialize the BDB db of the wallet.dat file. This format isn't explicitly documented anywhere, but the code and comments in BDB's source code in file `dbinc/db_page.h` describe it. This module just dumps all of the fields into a dict.

38ada892ed addrman: ensure old versions don't parse peers.dat (Vasil Dimov)
Pull request description:
Even though the format of `peers.dat` was changed in a backwards
incompatible way, it is not guaranteed that old versions will fail to
parse it. There is a chance that old versions parse its contents as
garbage and use it.
Old versions expect the "key size" field to be 32 and fail the parsing
if it is not. Thus, we put something other than 32 in it. This will make
versions between 0.11.0 and 0.20.1 deterministically fail on the new
format. Versions prior to https://github.com/bitcoin/bitcoin/pull/5941
will still parse it as garbage.
Also, introduce a way to increment the `peers.dat` format in a way that
does not necessary make older versions refuse to read it.

989e579d07 qt: Make transaction notification queue wallet specific (João Barbosa)
7b3b2303f4 move-only: Define TransactionNotification before TransactionTablePriv (João Barbosa)
Pull request description:
Currently `vQueueNotifications` holds transactions of any wallet, but the queue is dispatched on a given wallet and it assumes notifications are of that wallet.
This means that some transactions can be missed if multiple wallets are loaded.
Fix this by having a queue for each wallet.

5e146022da wallet: fix scanning progress calculation for single block range (Sebastian Falbesoner)
Pull request description:
If the blockchain is rescanned for a single block (i.e. start and stop hashes are equal, and with that also the estimated start/stop verification progress values) the progress calculation could lead to a NaN value caused by a division by zero (0.0/0.0), resulting in an invalid JSON result for the `getwalletinfo` RPC. This PR fixes this behaviour by setting the progress to zero in that special case. Fixes#20297.
The behaviour can easily be reproduced by continuously running single block rescans in an endless loop, e.g. via
```bash
#!/bin/bash
while true
do
bitcoin-cli rescanblockchain $(bitcoin-cli getblockcount)
done
```
and at the same time perform some `getwalletinfo` RPCs.
On the master branch, this leads to frequent invalid responses (tested on mainchain):
```
$ bitcoin-cli getwalletinfo
error: couldn't parse reply from server
$ curl --user `cat ~/.bitcoin/.cookie` --data-binary '{"jsonrpc": "1.0", "id": "curltest", "method": "getwalletinfo", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:8332/
{"result":{"walletname":"","walletversion":169900,"format":"bdb","balance":0.00000000,"unconfirmed_balance":0.00000000,"immature_balance":0.00000000,"txcount":0,"keypoololdest":1603677276,"keypoolsize":1000,"hdseedid":"3196e33ecb47c7130e6ca60f2f895f9259860dca","keypoolsize_hd_internal":1000,"paytxfee":0.00000000,"private_keys_enabled":true,"avoid_reuse":false,"scanning":{"duration":0,"progress":},"descriptors":false},"error":null,"id":"curltest"}
```
(note that missing value for "progress" in the JSON result).
On the PR branch, the behaviour doesn't occur anymore.
