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

2020-10-14Determine wallet file type based on file magicAndrew Chow
2020-10-13wallet: remove db mode stringIvan Metlushko
We never need to open database in read-only mode as it's controlled separately for every batch. Also we can safely create database if it doesn't exist already because require_existing option is verified in MakeDatabase before creating a new WalletDatabase instance.
2020-09-10bugfix: make LoadWallet assigns status alwaysAkio Nakamura
Although loadwallet() in rpcwallet.cpp assumes LoadWallet() always assign some value to the 'status', but LoadWallet() does not do so in some situation. This fixes above and prevends loadwallet() returns ambiguous error code.
2020-09-03refactor: Pass wallet database into CWallet::CreateRussell Yanofsky
No changes in behavior
2020-09-03wallet: Remove Verify and IsLoaded methodsRussell Yanofsky
Checks are now consolidated in MakeBerkeleyDatabase function instead of happening in higher level code. This commit does not change behavior except for error messages which now include more complete information.
2020-09-03refactor: Use DatabaseStatus and DatabaseOptions typesRussell Yanofsky
No changes in behavior. Just replaces arguments and return types
2020-09-03wallet: Add MakeDatabase functionRussell Yanofsky
New function is not currently called but will be called in upcoming commits. It moves database path checking, and existence checking, and already-loaded checking, and verification into a single function so this logic does not need to be repeated all over higher level wallet code, and so higher level code does not need to change when SQLite support is added in https://github.com/bitcoin/bitcoin/pull/19077. This also lets higher level wallet code make fewer assumptions about the contents of wallet directories. This commit just adds the new function and does not change behavior in any way.

2020-05-25Move RecoverDatabaseFile and RecoverKeysOnlyFilter into salvage.{cpp/h}Andrew Chow
2020-05-25Make BerkeleyBatch::Recover and WalletBatch::RecoverKeysOnlyFilter standaloneAndrew Chow
Instead of having these be class static functions, just make them be standalone. Also removes WalletBatch::Recover which just passed through to BerkeleyBatch::Recover.
2020-05-25Move BerkeleyEnvironment::Salvage into BerkeleyBatch::RecoverAndrew Chow
2020-05-25walletdb: remove fAggressive from SalvageAndrew Chow

2020-05-01wallet: Avoid translating RPC errors when loading walletsMarcoFalke
Common errors and warnings should be translated when displayed in the GUI, but not translated when displayed elsewhere. The wallet method CreateWalletFromFile does not know its caller, so this commit changes it to return a bilingual_str to the caller.

expose the "version" record 35e60e790f2cd602d1bdd0be835d27f0ba37efa9 Remove ReadVersion and WriteVersion (Andrew Chow) b3d4f6c9619142948ab3d53551b4f3c0d7d73bde Log the actual wallet file version (Andrew Chow) c88e87c3b2be3f97b712107e04285d06dfef3878 Remove nFileVersion from CWalletScanState (Andrew Chow) Pull request description: The wallet file version is stored in the "minversion" record, not the "version" record. 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. ACKs for top commit: jb55: ACK 35e60e7, I compiled locally as a quick sanity check. ryanofsky: utACK 35e60e790f2cd602d1bdd0be835d27f0ba37efa9. This code still pretty confusing, but a little simpler now. And the previous log statement was really misleading and useless compared to the new one here. meshcollider: Looks good, thanks! utACK 35e60e790f2cd602d1bdd0be835d27f0ba37efa9 Tree-SHA512: f782b2f215d07fbc9b806322bda8085445b81c02b65ca674a8c6a3e1de505a0abd050669afe0ead4778816144a1c18462e13930071cedb7227a058aeb39493f7
2019-07-22Remove ReadVersion and WriteVersionAndrew Chow
The "version" record that these functions read and write are not used anywhere in the code except for one place. There is no reason to expose these functions publicly. Furthermore, this avoids potential confusion as developers may mistake these functions for actually reading and writing the wallet version when they do not.

2019-03-14wallet: Improve log output for errors during loadGlenn Willen
When loading the wallet, display the entire path in error messages, instead of the name (which, for the default wallet, is the empty string.) When an exception occurs during wallet loading, display e.what() if possible, instead of nothing.

This change was requested by @TheBlueMatt and makes code that sets up mock databases cleaner. The mock database environment will now go out of scope and be reset on destruction so there is no need to call BerkeleyEnvironment::Reset() during wallet construction to clear out prior state. This change does affect bitcoin behavior slightly. On startup, instead of same wallet environments staying open throughout VerifyWallets() and OpenWallets() calls, VerifyWallets() will open and close an environment once for each wallet, and OpenWallets() will create its own environment(s) later.

This change was requested by Matt Corallo <git@bluematt.me> and makes code that sets up mock databases cleaner. The mock database environment will now go out of scope and be reset on destruction so there is no need to call BerkeleyEnvironment::Reset() during wallet construction to clear out prior state.
