Because new nodes pull from the first connected node the load
balancing of the first connection is more important than it should
be. This change puts Pieter's seed first, because its probably
the best maintained right now.
Fixes#1452. Until we can make the logic water-tight *and* are notified in every
case the balance might have changed, remove the premature optimization and
simply recompute the balance every half a second when the number of blocks changed.
Compiling boost::interprocess::message_queue against
boost 1.50 macports with -arch i386 (how releases are built,
for minimum download size and maximum compatibility) is failing:
src/qt/qtipcserver.cpp:37: error: no matching function for call to ‘boost::interprocess::message_queue_t<boost::interprocess::offset_ptr<void, int, long unsigned int, 0u> >::timed_receive(char (*)[257], long unsigned int, size_t&, unsigned int&, boost::posix_time::ptime&)’
This is probably a boost or macports bug, but since interprocess::message_queue
is only used for URI support, which isn't implemented on OSX anyway, I fixed
the build by #ifdef'ing out that code.
- add signals signMessage() and verifyMessage() in addressbookpage.cpp
- connect to them in bitcoingui.cpp to switch to the corresponding tab in the Sign/Verify Message dialog
- make gotoSignMessageTab() and gotoVerifyMessageTab() private slots
- remove unused #include <QDebug> and lblBTC label
- update Bitcoin input field to a BitcoinAmountField to allow Bitcoin unit selection
- use BitcoinUnits::format for the resulting amount parameter in the generated URI (always use BTC as per BIP21)
- move MAX_URI_LENGTH and EXPORT_IMAGE_SIZE to guiconstants.h
- add OptionsModel in AddressBookPage and use it in on_showQRCode_clicked() to pass it to QRCodeDialog
- add OptionsModel in QRCodeDialog to enable display unit updates
- add updateDisplayUnit() slot to be able to imediately update currently set bitcoin unit
- make all labels in the UI-file plain text
- resize dialog to match for an updated layout (fields are now stacked and new field)
- remove unused parameters from private slots
- only enable save button, when QR Code was generated
- show message when entered amound is invalid
- add read-only QPlainTextEdit field to output generated URI
Adds CBlock::CURRENT_VERSION and CTransaction::CURRENT_VERSION
constants, and makes non-CURRENT_VERSION transactions nonstandard.
This will help make future upgrades smoother.
- add UI-feedback via QValidatedLineEdit
- copy button for generated signature was moved to the signature output field
- add an addressbook button to verify message tab
- input fields are now evenly ordered for sign and verify tabs
- update FIRST_CLASS_MESSAGING support to ensure a good UX
- add a button and context menu entry in addressbook for verify message (to be consistent with sign message)
- focus is now only set/changed, when clearing input fields or adding an address via addressbook
- re-work / update some strings
- ensure model gets initialized in the SignVerifyMessageDialog constructor
- add checks for a valid model to both addressbook buttons
- remove unneeded includes for Qt GUI elements that are listed in ui_signverifymessagedialog.h anyway
Implement listunspent / getrawtransaction / createrawtransaction /
signrawtransaction, to support creation and
signing-on-multiple-device multisignature transactions.
This PULL reworks new (post-0.6.*) features of the
gettransaction/getblock RPC calls as follows:
It removes the 'decompositions' object argument from getblock,
replacing it just a list of transaction hashes; equivalent
(I believe) of passing the {"tx":"hash"} decomposition.
It replaces the 'decompositions' object argument of
gettransaction with a boolean flag; if true, returns
the same stuff that the {"script":"obj"} decomposition
would return (txins/txouts as hex, disassembled, and bitcoin
addresses).
It adds a "rawtx" field to the output of gettransaction,
that is the entire transaction serialized and hex-encoded.
It removes the "size" field from gettransaction, since the size
is trivial to compute from the "rawtx" field (either take the
length after hex-decoding, or just compute it as hex-length/2).
If the top-level object is an array, it is assumed to be an array of
JSON-RPC requests. An array is returned, containing one response (error or
not) per request, in the order submitted.
In a slight change in semantics, batched requests -always- return
an HTTP 200 OK status, even ones full of invalid or incorrect requests.
- remove "#include <QString>" as this is included in the header
- add some missing plural forms that can be translated
- change "yours" into "own address", which is easier to understand and translate in that context
- cleanup translatable strings to not include HTML or unneeded chars (e.g. ":")
- resize TransactionDescDialog a little (remove unwanted line-breaks with non english translations)
Bitcoin will not make an outbound connection to a network group
(/16 for IPv4) that it is already connected to. This means that
if an attacker wants good odds of capturing all a nodes outbound
connections he must have hosts on a a large number of distinct
groups.
Previously both inbound and outbound connections were used to
feed this exclusion. The use of inbound connections, which can be
controlled by the attacker, actually has the potential of making
sibyl attacks _easier_: An attacker can start up hosts in groups
which house many honest nodes and make outbound connections to
the victim to exclude big swaths of honest nodes. Because the
attacker chooses to make the outbound connection he can always
beat out honest nodes for the consumption of inbound slots.
At _best_ the old behavior increases attacker costs by a single
group (e.g. one distinct group to use to fill up all your inbound
slots), but at worst it allows the attacker to select whole
networks you won't connect to.
This commit makes the nodes use only outbound links to exclude
network groups for outbound connections. Fancier things could
be done, like weaker exclusion for inbound groups... but
simplicity is good and I don't believe more complexity is
currently needed.
Useful for developers who need to refer to futher back in debug.log history, but who don't want to
enable the -debug option and all the verbosity that comes with that.

This commit adds support for .onion addresses (mapped into the IPv6
by using OnionCat's range and encoding), and the ability to connect
to them via a SOCKS5 proxy.
Prior to this change, each TX typically generated 3+ debug messages,
askfor tx 8644cc97480ba1537214 0
sending getdata: tx 8644cc97480ba1537214
askfor tx 8644cc97480ba1537214 1339640761000000

CTxMemPool::accept() : accepted 8644cc9748 (poolsz 6857)
After this change, there is only one message for each valid TX received
CTxMemPool::accept() : accepted 22a73c5d8c (poolsz 42)
and two messages for each orphan tx received
ERROR: FetchInputs() : 673dc195aa mempool Tx prev not found 1e439346fc

The -debugnet option, or its superset -debug, will restore the full debug
output.
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.
