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. ACKs for top commit: MarcoFalke: approach ACK 5f9c0b6360 laanwj: Code review ACK 5f9c0b6360215636cfa62a70d3a70f1feb3977ab jonatack: ACK 5f9c0b6360215636cfa62a70d3a70f1feb3977ab, approach seems fine, code review, only skimmed the test changes but they look well done, rebased on current master, debug built and verified the `wallet_upgradewallet.py` test runs green both before and after running `test/get_previous_releases.py -b v0.19.1 v0.18.1 v0.17.2 v0.16.3 v0.15.2` Tree-SHA512: 7c4ebf420850d596a586cb6dd7f2ef39c6477847d12d105fcd362abb07f2a8aa4f7afc5bfd36cbc8b8c72fcdd1de8d2d3f16ad8e8ba736b6f4f31f133fe5feba

In the source code, `WalletFeature::FEATURE_LATEST` has been modified to be large, so that the minversion is too high

for a current build of the wallet.

The wallet has then been created with the RPC `createwallet high_minversion true true`, so that a blank wallet with

Utilities for working directly with the wallet's BDB database file
|
||||
|
||||
This is specific to the configuration of BDB used in this project:
|
||||
- pagesize: 4096 bytes
|
||||
- Outer database contains single subdatabase named 'main'
|
||||
- btree
|
||||
- btree leaf pages
|
||||
|
||||
Each key-value pair is two entries in a btree leaf. The first is the key, the one that follows
|
||||
is the value. And so on. Note that the entry data is itself not in the correct order. Instead
|
||||
entry offsets are stored in the correct order and those offsets are needed to then retrieve
|
||||
the data itself.
|
||||
|
||||
Page format can be found in BDB source code dbinc/db_page.h
|
||||
This only implements the deserialization of btree metadata pages and normal btree pages. Overflow
|
||||
pages are not implemented but may be needed in the future if dealing with wallets with large
|
||||
transactions.
|
||||
|
||||
`db_dump -da wallet.dat` is useful to see the data in a wallet.dat BDB file
