Exact amounts are now allocated directly to denominated
funds then submitted to the pool. This improves anonymity
by never having non-denomination inputs enter or exit the pool.
Randomness has also been added to the amount of each session to
improve anonymity.
- Fixed a few issues when calculating progress including some variables that should be limited to 1 (a and b). GetDenominatedBalance also seemed to be giving bad results so I rewrote it to be cleaner, not sure if that was a part of the problem.
- Progress bar is only recalculated when all inputs in wallet have been confirmed (will stop the progress from jumping around)
More info regarding KeePass: http://keepass.info/
KeePass integration will use KeePassHttp (https://github.com/pfn/keepasshttp/) to facilitate communications between the client and KeePass. KeePassHttp is a plugin for KeePass 2.x and provides a secure means of exposing KeePass entries via HTTP for clients to consume.
The implementation is dependent on the following:
- crypter.h for AES encryption helper functions.
- rpcprotocol.h for handling RPC communications. Could only be used partially however due some static values in the code.
- OpenSSL for base64 encoding. regular util.h libraries were not used for base64 encoding/decoding since they do not use secure allocation.
- JSON Spirit for reading / writing RPC communications
The following changes were made:
- Added CLI options in help
- Added RPC commands: keepass <genkey|init|setpassphrase>
- Added keepass.h and keepass.cpp which hold the integration routines
- Modified rpcwallet.cpp to support RPC commands
The following new options are available for darkcoind and darkcoin-qt:
-keepass Use KeePass 2 integration using KeePassHttp plugin (default: 0)
-keepassport=<port> Connect to KeePassHttp on port <port> (default: 19455)
-keepasskey=<key> KeePassHttp key for AES encrypted communication with KeePass
-keepassid=<name> KeePassHttp id for the established association
-keepassname=<name> Name to construct url for KeePass entry that stores the wallet passphrase
The following rpc commands are available:
- keepass genkey: generates a base64 encoded 256 bit AES key that can be used for the communication with KeePassHttp. Only necessary for manual configuration. Use init for automatic configuration.
- keepass init: sets up the association between darkcoind and keepass by generating an AES key and sending an association message to KeePassHttp. This will trigger KeePass to ask for an Id for the association. Returns the association and the base64 encoded string for the AES key.
- keepass setpassphrase <passphrase>: updates the passphrase in KeePassHttp to a new value. This should match the passphrase you intend to use for the wallet. Please note that the standard RPC commands walletpassphrasechange and the wallet encrption from the QT GUI already send the updates to KeePassHttp, so this is only necessary for manual manipulation of the password.
Sample initialization flow from darkcoin-qt console (this needs to be done only once to set up the association):
- Have KeePass running with an open database
- Start darkcoin-qt
- Open console
- type: "keepass init" in darkcoin-qt console
- (keepass pops up and asks for an association id, fill that in). Example: mydrkwallet
- response: Association successful. Id: mydrkwalletdarkcoin - Key: AgQkcs6cI7v9tlSYKjG/+s8wJrGALHl3jLosJpPLzUE=
- Edit darkcoin.conf and fill in these values
keepass=1
keepasskey=AgQkcs6cI7v9tlSYKjG/+s8wJrGALHl3jLosJpPLzUE=
keepassid=mydrkwallet
keepassname=testwallet
- Restart darkcoin-qt
At this point, the association is made. The next action depends on your particular situation:
- current wallet is not yet encrypted. Encrypting the wallet will trigger the integration and stores the password in KeePass (Under the 'KeePassHttp Passwords' group, named after keepassname.
- current wallet is already encrypted: use "keepass setpassphrase <passphrase>" to store the passphrase in KeePass.
At this point, the passphrase is stored in KeePassHttp. When Unlocking the wallet, one can use keepass as the passphrase to trigger retrieval of the password. This works from the RPC commands as well as the GUI.
Darksend is now capable of taking queue objects (which show who wants to mix what)
and looking at it's own inputs to see if it's at all possible to join their mixing
session. This plus other improvements should make Darksend much faster for mixing
coins.
- Progress bar is far more accurate now. It only takes into account the inputs that could possibly go into Darksend and ignores the rest.
- Darksend can support down to 1.5DRK now.
- New "masternode outputs" command for start-many
Size specifiers are no longer needed now that we use typesafe tinyformat
for string formatting, instead of the system's sprintf.
No functional changes.
This continues the work in #3735.

55a1db4 Solve chainActive-related locking issues (Wladimir J. van der Laan)
e07c943 Add AssertLockHeld for cs_main to ChainActive-using functions (Wladimir J. van der Laan)
- In wallet and GUI code LOCK cs_main as well as cs_wallet when
necessary
- In main.cpp SendMessages move the TRY_LOCK(cs_main) up, to encompass the call
to IsInitialBlockDownload.
- Make ActivateBestChain, AddToBlockIndex, IsInitialBlockDownload,
InitBlockIndex acquire the cs_main lock
Fixes#3997
Now that AddToWallet is called when loading transactions from the
wallet database, BindWallet can be integrated into that and does not
need to be an extra step.
Leaves behaviour unchanged, but makes the
fFromLoadWallet/!fFromLoadWallet paths in AddToWallet a bit more
symmetric.
Amend to d5f1e72. It turns out that BerkelyDB was including inttypes.h
indirectly, so we cannot fix this with just macros.
Trivial commit: apply the following script to all .cpp and .h files:
# Middle
sed -i 's/"PRIx64"/x/g' "$1"
sed -i 's/"PRIu64"/u/g' "$1"
sed -i 's/"PRId64"/d/g' "$1"
# Initial
sed -i 's/PRIx64"/"x/g' "$1"
sed -i 's/PRIu64"/"u/g' "$1"
sed -i 's/PRId64"/"d/g' "$1"
# Trailing
sed -i 's/"PRIx64/x"/g' "$1"
sed -i 's/"PRIu64/u"/g' "$1"
sed -i 's/"PRId64/d"/g' "$1"
After this commit, `git grep` for PRI.64 should turn up nothing except
the defines in util.h.
As the tinyformat-based formatting system (introduced in b77dfdc) is
type-safe, no special format characters are needed to specify sizes.
Tinyformat can support (ignore) the C99 prefixes such as "ll" but
chokes on MSVC's inttypes.h defines prefixes such as "I64X". So don't
include inttypes.h and define our own for compatibility.
(an alternative would be to sweep the entire codebase using sed -i to
get rid of the size specifiers but this has less diff impact)
Compiling with -DDEBUG_LOCKORDER and running the qa/rpc-test/ regression
tests uncovered a couple of wallet methods that should (but didn't)
acquire the cs_wallet mutext.
I also changed the AssertLockHeld() routine print to stderr and
abort, instead of printing to debug.log and then assert()'ing.
It is annoying to look in debug.log to find out which
AssertLockHeld is failing.
5770254 Copyright header updates s/2013/2014 on files whose last git commit was done in 2014. contrib/devtools/fix-copyright-headers.py script to be able to perform this maintenance task with ease during the rest of the year, every year. Modifications to contrib/devtools/README.md to document what fix-copyright-headers.py does. (gubatron)
Adds a "walletconflicts" array to transaction info; if
a wallet transaction is mutated, the alternate transaction id
or ids are reported there (usually the array will be empty).
Metadata from the original transaction is copied to the mutant,
so the transaction time and "from" account of the mutant are
reported correctly.
Extend CMerkleTx::GetDepthInMainChain with the concept of
a "conflicted" transaction-- a transaction generated by the wallet
that is not in the main chain or in the mempool, and, therefore,
will likely never be confirmed.
GetDepthInMainChain() now returns -1 for conflicted transactions
(0 for unconfirmed-but-in-the-mempool, and >1 for confirmed).
This makes getbalance, getbalance '*', and listunspent all agree when there are
mutated transactions in the wallet.
Before:
listunspent: one 49BTC output
getbalance: 96 BTC (change counted twice)
getbalance '*': 46 BTC (spends counted twice)
After: all agree, 49 BTC available to spend.
