2021-10-29refactor: get wallet path relative to wallet_dirMichael Dietz
Now that boost has been updated > 1.60, we can simplify how we get wallet path relative to wallet_dir by using: `boost::filesystem::lexically_relative`
2021-10-05refactor: Block unsafe fs::path std::string conversion callsRussell Yanofsky
There is no change in behavior. This just helps prepare for the transition from boost::filesystem to std::filesystem by avoiding calls to methods which will be unsafe after the transaction to std::filesystem to due lack of a boost::filesystem::path::imbue equivalent and inability to set a predictable locale.

directory d44a261acff40c1c8727d3cc0106bde65a6416d0 Fix issues when `walletdir` is root directory (unknown) Pull request description: + Remove one character less from wallet path + After testing lot of random strings with special chars in `wallet_name`, I found that the issue was not related to special characters in the name. Reviewing PR https://github.com/bitcoin/bitcoin/pull/21907 helped me resolve the issue. **Real issue**: If the path mentioned in `walletdir` is a root directory, first character of the wallet name or path is removed **Solution**: `if` statement to check `walletdir` is a root directory Fixes: https://github.com/bitcoin/bitcoin/issues/21510 https://github.com/bitcoin/bitcoin/issues/21501 Related PR: https://github.com/bitcoin/bitcoin/pull/20080 Consider the wallet directories `w1` and `w2` saved in `D:\`.

2020-12-04wallet: List all wallets in non-SQLite or non-BDB buildsRussell Yanofsky
This commit does not change behavior when bitcoin is built normally with both the SQLite and BDB libraries. It just makes non-SQLite and non-BDB builds more similar to the normal build. Specifically: - It makes wallet directory lists always include all wallets so wallets don't appear missing depending on the build. - It now triggers specific "Build does not support SQLite database format" and "Build does not support Berkeley DB database format" errors if a wallet can't be loaded instead of the more ambiguous and scary "Data is not in recognized format" error.
2020-12-04refactor: Consolidate redundant wallet database path and exists functionsRussell Yanofsky
No change in behavior. Just remove a little bit of code, reduce macro usage, remove duplicative functions, and make BDB and SQLite implementations more consistent with each other.
2020-12-04refactor: Replace ListWalletDir() function with ListDatabases()Russell Yanofsky
No change to behavior. This is just cleanup after previous MOVEONLY commit to make db.h list function fit conventions of surrounding functions.
2020-12-04MOVEONLY: Move IsBDBFile, IsSQLiteFile, and ListWalletDirRussell Yanofsky
This commit does not change to any code and behavior. It it is easily reviewed with the --color-moved=dimmed_zebra git diff option. Motivation for this change is to: - Consolidate redundant functions IsBDBFile /ExistsBerkeleyDatabase / SplitWalletPath, and IsSQLiteFile / ExistsSQLiteDatabase in the next commits - Detect SQLite wallets consistently regardless whether bitcoin is built with SQLite support in the next commits - Avoid attempting to open SQLite databases with the BDB library when bitcoin is built without SQLite support in the next commits

[1] Remove them from the wallet because they are either unused or useless. The feature to interrupt a periodic flush is useless because all wallets have just been flushed https://github.com/bitcoin/bitcoin/blob/9ccaee1d5e2e4b79b0a7c29aadb41b97e4741332/src/init.cpp#L194 and another flush should be a noop. Also, they will be flushed again shortly after https://github.com/bitcoin/bitcoin/blob/9ccaee1d5e2e4b79b0a7c29aadb41b97e4741332/src/init.cpp#L285, so even if repeated flushes weren't a noop, doing 3 instead of 2 shouldn't matter too much at this point. Also, the wallet is flushed every two seconds in the worst case, so if this is an expensive operation, that period should be readjusted. (Or bdb should be removed altogether #18916) [1] Replacement of `boost::thread` with `std::thread` should happen because: * The boost thread dependency is slow to compile * Boost thread is less maintained than the standard lib * Boost thread is mostly redundant to the standard lib * Global interruption points via exceptions are hard to keep track of during review and easy to get wrong during runtime (e.g. accidental `catch (...)`) ACKs for top commit: fanquake: ACK fa1c74fd0342b74d44cc4e41fff3890c1434e8f7 Tree-SHA512: b166619256de2ef4325480fa1367f68bc9371ad785ec503aed61eab41ba61f1a9807aab25451a24efda3db64855c9ba0025645b98bc58557bc3ec56c5b3297d0

However "version" is no longer used anywhere except to record the highest versioned client which has opened a wallet file (which is currently only used to check whether this was most recently opened by a 0.4.0 or 0.5.0rc1 client which had a broken wallet encryption implementation). Furthermore, "version" was logged to the debug.log which is confusing because it is not the actual wallet file version. This PR changes it so that this confusion largely no longer exists. The wallet file version logging is changed to use "minversion" and reading and writing the "version" record is no longer publicly exposed to prevent potential confusion about whether the actual file version is being read or written. Lastly, in the one place it is actually used, the variable name is changed from nFileVersion to last_client to better reflect what that record actually represents.
