Since the minimum signed integer cannot be represented as positive so long as its type is signed, and it's not well-defined what happens if you make it unsigned before negating it, we instead increment the negative integer by 1, convert it, then increment the (now positive) unsigned integer by 1 to compensate
Implement the following rules:
* Interpret [X]:Y as host=X port=Y, if Y is an integer
* Interpret X:Y as host=X port=Y, if Y is an integer and X contains no colon
* Interpret X:Y as host=X:Y port=default otherwise
On Linux/Mac the command-line options were printed to stderr when the button
was pressed in the debug window, resulting in confusion. This is fixed
in this commit by adding a separate method.
The current order of menu options in the tray menu doesn't really match expected usage patterns, this commit changes it to more logical order.
- Toggle show/hide first (unchanged)
- Then, send/receive coins actions, which are the critical functionality of bitcoin
- Then, sign/verify message
- Then finally the options, and closing with the debug window
This is necessary as any strings have changed since last time.
Also the python script used to extract bitcoinstrings.cpp, extract_strings_qt.py
now sorts the strings before generating the output file. This results in more
deterministic output and thus smaller diffs.
- extend network options with a SOCKS version selection
- changing "Unit to show amounts in:" now also updates the unit used in the transaction fee box
- string updates
- link Apply button and OK button when enabling or disabling them
- use LookupNumeric() from netbase to verify proxy address (via an EventFilter)
- change proxy address field to QValidatedLineEdit and add visual feedback
- add a status label used for displaying a message for invalid proxy addresses
- allow usage of IPv6 address as proxy address
- added warning message when enabling / disabling SOCKS proxy
The option to open the debug logfile from the debug window was implemented only for
windows. By using `QDesktopServices::openUrl` it now works on any platform.
AvailableCoins() makes a vector of available outputs which is then passed to SelectCoinsMinConf(). This allows unit tests to test the coin selection algorithm without having the whole blockchain available.
Newlines in JSON strings are against the JSON spec,
so remove them from the script*.json unit tests to
make python's jsonrpc happy (json::spirit didn't care).
This adds a field labelled 'Immature' in the overview section under the 'unconfirmed' field, which shows mined
income that has not yet matured (which is currently not displayed anywhere, even though the transactions
exist in the transaction list). To do that I added a 'GetImmatureBalance' method to the wallet, and connected
that through to the GUI as per the 'GetBalance' and 'GetUnconfirmedBalance' methods. I did a small 'no-op'
change to make the code in adjacent functions a little more readable (imo); it was a change I had made in my
repo earlier...but I thought it wouldn't hurt so left it in. Immature balance comes from mined income that is
at least two blocks deep in the chain (same logic as displayed transactions).
My reasoning is:
- as a miner, it's a critical stat I want to see
- as a miner, and taking into account the label 'immature', the uncertainty is pretty clearly implied
- those numbers are already displayed in the transaction list
- this makes the overview numbers add up to what's in the transaction list
- it's not displayed if the immature balance is 0, so won't bother non-miners
I also 'cleaned' the overview UI a little, moving code to the XML and removing HTML.
Using this modification it should be relatively easy to, at a later
time, listen on multiple addresses (even Unix domain sockets should be
possible).

The RPC server now listens for, and handles, incoming connections on
both IPv4 as well as IPv6.
If available (and usable) it uses a dual IPv4/IPv6 socket on systems
that support it (e.g. Linux and BSDs) and falls back to separate
IPv4/IPv6 sockets on systems that don't (e.g. Windows).

This allows more flexibility in the RPC code, e.g. making it easier to
handle multiple simultaneous connections later on.
Currently asynchronous I/O is only used to listen for and accept
incoming connections. Asynchronous reading/writing is more involved.

This introduces internal types:
* CKeyID: reference (hash160) of a key
* CScriptID: reference (hash160) of a script
* CTxDestination: a boost::variant of the former two
CBitcoinAddress is retrofitted to be a Base58 encoding of a
CTxDestination. This allows all internal code to only use the
internal types, and only have RPC and GUI depend on the base58 code.
Furthermore, the header dependencies are a lot saner now. base58.h is
at the top (right below rpc and gui) instead of at the bottom. For the
rest: wallet -> script -> keystore -> key. Only keystore still requires
a forward declaration of CScript. Solving that would require splitting
script into two layers.

Any problems seen during deserialization will throw an uncaught
exception, crashing the entire bitcoin process. Properly return an
error instead, so that we may at least log the error and gracefully
shutdown other portions of the app.
More than doubles the speed of verifying already-cached signatures
that use compressed pubkeys:
Before: ~200 microseconds
After: ~80 microseconds
(no caching at all: ~3,300 microseconds per signature)
Also encapsulates the signature cache code in a class
and fixes a signed/unsigned comparison warning.
Satoshi's commits fdbf76d and c8ad9b8 (SVN import) removed the
DB_PRIVATE flag from the environment. In part, this enables processes
other than bitcoind to examine the active database environment.
However, this incurs a slight performance penalty versus working
entirely within application memory (DB_PRIVATE). Because bitcointools
and other direct-BDB-accessing tools are not used by the vast
majority of users, prefer to default with DB_PRIVATE with the option
of disabling it if needed via -privdb=0.
- Signals now go directly from the core to WalletModel/ClientModel.
- WalletModel subscribes to signals on CWallet: Prepares for multi-wallet support, by no longer assuming an implicit global wallet.
- Gets rid of noui.cpp, the few lines that were left are merged into init.cpp
- Rename wxXXX message flags to MF_XXX, to make them UI indifferent.
- ThreadSafeMessageBox no longer returns the value `4` which was never used, converted to void.
Gets rid of `MainFrameRepaint` in favor of specific update functions that tell the UI exactly what changed.
This improves the efficiency of various handlers. Also fixes problems with mined transactions not showing up until restart.
The following notifications were added:
- `NotifyBlocksChanged`: Block chain changed
- `NotifyKeyStoreStatusChanged`: Wallet status (encrypted, locked) changed.
- `NotifyAddressBookChanged`: Address book entry changed.
- `NotifyTransactionChanged`: Wallet transaction added, removed or updated.
- `NotifyNumConnectionsChanged`: Number of connections changed.
- `NotifyAlertChanged`: New, updated or cancelled alert. As this finally makes it possible for the UI to know when a new alert arrived, it can be shown as OS notification.
These notifications could also be useful for RPC clients. However, currently, they are ignored in bitcoind (in noui.cpp).
Also brings back polling with timer for numBlocks in ClientModel. This value updates so frequently during initial download that the number of signals clogs the UI thread and causes heavy CPU usage. And after initial block download, the value changes so rarely that a delay of half a second until the UI updates is unnoticable.
Cleans up and organizes several scattered functions and variables related to
the BDB env. Class CDBInit() existed to provide a
guaranteed-via-C++-destructor cleanup of the db environment.
A formal CDBEnv class provides all of this inside a single wrapper.
If Reorganize() fails, then its caller, CBlock::SetBestChain(),
will call TxnAbort().
Redundant TxnAbort() calls are harmless. The second will return an
error return value, with no other side effects. TxnAbort() return
values are generally never checked. The impact is nil.
