e5468a19d1 Remove unreachable help conditions (lutangar)
Pull request description:
These conditions on `request.fHelp`, which appears in the body of the following functions are never reached:
* `walletpassphrase`
* `walletpassphrasechange`
* `encryptwallet`
```
...
if (request.fHelp || request.params.size() != 0) {
throw std::runtime_error("");
}
...
if (request.fHelp)
return true;
...
```
The first condition would throw if `request.fHelp` evaluates to `true`.

Pull request description:
This is an implementation of the [Branch and Bound coin selection algorithm written by Murch](http://murch.one/wp-content/uploads/2016/11/erhardt2016coinselection.pdf) (@xekyo). I have it set so this algorithm will run first and if it fails, it will fall back to the current coin selection algorithm. The coin selection algorithms and tests have been refactored to separate files instead of having them all in wallet.cpp.
I have added some tests for the new algorithm and a test for all of coin selection in general. However, more tests may be needed, but I will need help with coming up with more test cases.
This PR uses some code borrowed from #10360 to use effective values when selecting coins.

b4bc32a451 [wallet] Get rid of CWalletTx default constructor (Russell Yanofsky)
a128bdc9e1 [wallet] Construct CWalletTx objects in CommitTransaction (Russell Yanofsky)
Pull request description:
Two commits:
- `Construct CWalletTx objects in CommitTransaction` moves a bunch of CWalletTx initialization into CWallet::CommitTransaction to dedup some code and avoid future inconsistencies in how wallet transactions are created.
- `Get rid of CWalletTx default constructor` does what is described and eliminates the possibility of empty transaction entries being inadvertently created by mapWallet[hash] accesses.
Both of these changes were originally part of #9381

Failure looks like:
Entering test case "ComputeTimeSmart"
test_bitcoin: sync.cpp:100: void potential_deadlock_detected(const std::pair<void*, void*>&, const LockStack&, const LockStack&): Assertion `false' failed.
unknown location(0): fatal error in "ComputeTimeSmart": signal: SIGABRT (application abort requested)
wallet/test/wallet_tests.cpp(566): last checkpoint
Reproducible with:
./configure --enable-debug
make -C src test/test_bitcoin && src/test/test_bitcoin --log_level=test_suite --run_test=wallet_tests/ComputeTimeSmart
Happens due to "92fabcd443 Add LookupBlockIndex function" which acquires
cs_main from inside CWallet::ComputeTimeSmart.

42343c748 Split up and sanitize CAccountingEntry serialization (Pieter Wuille)
029ecac1b Split up and sanitize CWalletTx serialization (Pieter Wuille)
Pull request description:
This is a small subset of changes taken from #10785, fixing a few of the craziest constness violations in the serialization code.
`CWalletTx` currently serializes some of its fields by embedding them in a key-value `mapValue`, which is modified (and then fixed up) even from the `Serialize` method (for which `mapValue` is const). `CAccountingEntry` goes even further in that it stores such a map by appending it into `strComment` after a null char, which is again later fixed up again.
Fix this by splitting the serialization and deserialization code, and making the serialization act on a copy of `mapValue` / `strComment`.

Allows SelectCoinsMinConf and SelectCoins be able to switch between
using BnB or Knapsack for choosing coins.
Has SelectCoinsMinConf do the preprocessing necessary to support either
BnB or Knapsack. This includes calculating the filtering the effective
values for each input.
Uses BnB in CreateTransaction to find an exact match for the output.
If BnB fails, it will fallback to the Knapsack solver.
|
|
|
|
|
|
Moves the current coin selection algorithm out of SelectCoinsMinConf
and puts it in coinselection.{cpp,h}. The new function, KnapsackSolver,
instead of taking a vector of COutputs, will take a vector of CInputCoins
that is prepared by SelectCoinsMinConf.
|
|
|
|
Changes CInputCoin to coinselection and to use CTransactionRef in
order to avoid a circular dependency. Also moves other coin selection
specific variables out of wallet.h to coinselectoin.h
|
|
Instead of specifying 3 parameters, use a struct for those parameters
in order to reduce the number of arguments to SelectCoinsMinConf.
|
|
|
|
Create a new file for coin selection logic and implement the BnB algorithm in it.

Have CInputCOin store effective value information. This includes the effective
value itself, the fee, and the long term fee for the input

* Z is the zone designator for the zero UTC offset.
* T is the delimiter used to separate date and time.
This makes it clear for the end-user that the date/time logged is
specified in UTC and not in the local time zone.

No change in behavior in the normal case. But buggy mapWallet lookups with
invalid txids will now throw exceptions instead of inserting dummy entries into
the map, and potentially causing segfaults and other failures.
This also makes it a compiler error to use the mapWallet[hash] syntax which
could create dummy entries.
|
|
Construct CWalletTx objects in CWallet::CommitTransaction, instead of having
callers do it. This ensures CWalletTx objects are constructed in a uniform way
and all fields are set.
This also makes it possible to avoid confusing and wasteful CWalletTx copies in
https://github.com/bitcoin/bitcoin/pull/9381
There is no change in behavior.

be8ab7d08 Create new wallet databases as directories rather than files (Russell Yanofsky)
26c06f24e Allow wallet files not in -walletdir directory (Russell Yanofsky)
d8a99f65e Allow wallet files in multiple directories (Russell Yanofsky)
Pull request description:
This change consists of three commits:
* The first commit is a pure refactoring that removes the restriction that two wallets can only be opened at the same time if they are contained in the same directory.
* The second commit removes the restriction that `-wallet` filenames can only refer to files in the `-walletdir` directory.
* The third commit makes second commit a little safer by changing bitcoin to create wallet databases as directories rather than files, so they can be safely backed up.
All three commits should be straightforward:
* The first commit adds around 20 lines of new code and then updates a bunch of function signatures (generally updating them to take plain fs::path parameters, instead of combinations of strings, fs::paths, and objects like CDBEnv and CWalletDBWrapper).
* The second commit removes two `-wallet` filename checks and adds some test cases to the multiwallet unit test.
* The third commit just changes the mapping from specified wallet paths to bdb environment & data paths.

**Note:** For anybody looking at this PR for the first time, I think you can skip the comments before _20 Nov_ and start reading at https://github.com/bitcoin/bitcoin/pull/11687#issuecomment-345625565. Comments before _20 Nov_ were about an earlier version of the PR that didn't include the third commit, and then confusion from not seeing the first commit.

ebfe217b1 Stop using CBase58Data for ext keys (Pieter Wuille)
32e69fa0d Replace CBitcoinSecret with {Encode,Decode}Secret (Pieter Wuille)
Pull request description:
This PR contains some of the changes left as TODO in #11167 (and built on top of that PR). They are not intended for backporting.
This removes the `CBase58`, `CBitcoinSecret`, `CBitcoinExtKey`, and `CBitcoinExtPubKey` classes, in favor of simple `Encode`/`Decode` functions. Furthermore, all Bitcoin-specific logic (addresses, WIF, BIP32) is moved to `key_io.{h,cpp}`, leaving `base58.{h,cpp}` as a pure utility that implements the base58 encoding/decoding logic.

2736c9e05 Avoid unintentional unsigned integer wraparounds in tests (practicalswift)
Pull request description:
Avoid unintentional unsigned integer wraparounds in tests.
This is a subset of #11535 as suggested by @MarcoFalke :-)
Tree-SHA512: 4f4ee8a08870101a3f7451aefa77ae06aaf44e3c3b2f7555faa2b8a8503f97f34e34dffcf65154278f15767dc9823955f52d1aa7b39930b390e57cdf2b65e0f3

This change should make it easier for users to make complete backups of wallets
because they can now just back up the specified `-wallet=<path>` path directly,
instead of having to back up the specified path as well as the transaction log
directory (for incompletely flushed wallets).
Another advantage of this change is that if two wallets are located in the same
directory, they will now use their own BerkeleyDB environments instead using a
shared environment. Using a shared environment makes it difficult to manage and
back up wallets separately because transaction log files will contain a mix of
data from all wallets in the environment.
|
|
Remove restriction that -wallet filenames can only refer to files in the
-walletdir directory.
|
|
Remove requirement that two wallet files can only be opened at the same time if
they are contained in the same directory.
This change mostly consists of updates to function signatures (updating
functions to take fs::path arguments, instead of combinations of strings,
fs::path, and CDBEnv / CWalletDBWrapper arguments).
|

New global variables were introduced in #11882 and not setting them causes:
wallet/test/wallet_tests.cpp(638): error in "ListCoins": check wallet->CreateTransaction({recipient}, wtx, reservekey, fee, changePos, error, dummy) failed
wallet/test/wallet_tests.cpp(679): error in "ListCoins": check list.begin()->second.size() == 2 failed [1 != 2]
wallet/test/wallet_tests.cpp(686): error in "ListCoins": check available.size() == 2 failed [1 != 2]
wallet/test/wallet_tests.cpp(705): error in "ListCoins": check list.begin()->second.size() == 2 failed [1 != 2]
It's possible to reproduce the failure reliably by running:
src/test/test_bitcoin --log_level=test_suite --run_test=wallet_tests/ListCoins
Failures happen nondeterministically because boost test framework doesn't run
tests in a specified order, and tests that run previously can set the global
variables and mask the bug.

90ba2df11 Fix missing cs_main lock for GuessVerificationProgress() (Jonas Schnelli)
Pull request description:
`GuessVerificationProgress()` needs `cs_main` due to accessing the `pindex->nChainTx`.
This adds a `AssertLockHeld` in `GuessVerificationProgress()` and adds the missing locks in...
* `LoadChainTip()`
* `ScanForWalletTransactions()` (got missed in #11281)
* GUI, `ClientModel::getVerificationProgress()` <--- **this may have GUI performance impacts**, but could be relaxed later with a cache or something more efficient.
