Changes for the datadir chooser have made it impossible to specify
the network (testnet/regtest) in the configuration file for the GUI.
Reorganize the initialization sequence to make this possible again.
- Moves the "datadir" QSetting so that is no longer dependent on the
network-specific application name (doing otherwise would create a
chicken-and-egg problem).
- Re-initialize translations after choosing network. There may be a
different language configured in network-specific settings
(slim chance, but handle it for sanity).
Fixes point 1 of #3840.

This resolves a case in which a mismatch could be used to bloat up the
mempool by sending transactions that pay enough fee to relay, but not
to be mined, with the default policies.

Last Transifex pull (064a690) introduced a few control characters
into the Korean translation, which sometimes causes the build to fail.
Manually remove these characters for now to get the build working --
they should still be removed at Transifex too.

When bitcoind can't bind, bitcoin server (or Bitcoin Core Daemon) is
probably already running. Add the missing word "server". Bitcoin itself
is definitely running ;-)
Add _(...) so the string can be localized.

These days we regard transactions with one confirmation to be
'Confirmed'.
Waiting for 6 confirmations is a recommendation but should not
keep the transaction shown as unconfirmed.
Misc code sanity:
- Merge maturity/status enums, they had become completely disjunct
- 'confirmed' flag is now called 'countsForBalance' for clarity
By default tinyformat errors such as 'wrong number of conversion
specifiers in format string' cause an assertion failure.
Raise an exception instead so that error handling can recover or can
show an appropriate error.
IIRC this was the case with 0.8.6, so let's keep this to avoid the risk
of losing connectable nodes with 0.9 release.
Also our miniupnpc library was recently updated and I've heard
reports that it works better than before now.
Just a pet peeve.
(PrintException has exactly the same body as PrintExceptionContinue but
does a re-throw at the end. Move these re-throws to the call
site, this aids understanding what is going on as well as eliminates a
bit of code duplication in util.cpp)
While building protobuf in different environments we noticed that
the host tool protoc was slightly different between builds (a symbol table
sorting issue).
Add a deterministic seed as well as disable zlib support.

No effect on final executables so no version bump.
This was a bad idea. This can't be solved with macros as any
other library that includes inttypes.h will get in the way.
The parent commit has removed all usages from the source, this commit
removes the definition.
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)
Boost iostreams was picking up libz-dev in VirtualBox, as the recommended
way to build is now to make a VM with all dependency packages installed.
This caused a divergence between KVM/LXC build and VirtualBox
build results.
Fix this in the simplest possible way: add the libz-dev package.
We were losing information about sent/received by overriding the
category in case of a conflicted transaction.
Hence, remove the "conflicted" category.
Conflicted status of a transaction can still be determined by looking
for confirmations<0.
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.
- DecodeDumpTime was passing a statically allocated facet object to
std::locale. However, "The constructed locale object takes over
responsibility for deleting this facet object." causing a free()
crash on scope exit. Fixes#3670.
- EncodeDumpTime was using the wrong format character for dates
(appears accidentally introduced in 51ed9ec9)

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.
- Exclamation mark icon for conflicted transactions
- Show mouseover status for conflicted transactions as "conflicted"
- Don't show inactive transactions on overview page overview
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.
Reworked send.sh, so it works properly on my Mac (killall send.sh
doesn't work, because the process name is 'bash' not 'send.sh').
So now send.sh writes a .send.pid file, and invoking it as
send.sh -STOP (as the bitcoind -walletnotify) signals that PID.
This allows getting raw transaction data from the wallet even if the
transaction is no longer in the blockchain / mempool (for example if it
got orphaned due to malleability abuse).

The FTP server what we get libpng from only keeps the latest version in its main folder. Older versions are in the "history" folder. Apparently version 1.6.9 has been released, so 1.6.8 has moved to the history folder.
It appears that the output was different every time.
This doesn't affect the final bitcoind/bitcoin-qt, but is confusing
nevertheless.
Fix it by using FAKETIME and zipping files in deterministic order.
OpenSSL was embedding a timestamp causing its build to be
non-deterministic.
Change deps-linux to be deterministic by using FAKETIME
as needed and disabling it when it gets in the way.

In case the total number of orphan blocks in memory exceeds a limit

- remove btc address length from address validator
- add an optional btc address check in validated line edit that defaults

- an isAcceptable() check is added to validated line edit on focus out
which only kicks in, when a validator is used with that widget
- remove an isAcceptable() check from sendcoinsentry.cpp
- remove obsolete attributes from ui files, which are set by calling
GUIUtil::setupAddressWidget()
- move some more things to GUIUtil::setupAddressWidget() and remove them
from normal code e.g. placeholder text
This changes the block processing logic from "try to atomically switch
to a new block" to a continuous "(dis)connect a block, aiming for the
assumed best chain".
This means the smallest atomic operations on the chainstate become
individual block connections or disconnections, instead of entire
reorganizations. It may mean that we try to reorganize to one block,
fail, and rereorganize again to the old block. This is slower, but
doesn't require unbounded RAM.
It also means that a ConnectBlock which fails may be no longer called
from the ProcessBlock which knows which node sent it. To deal with that,
a mapBlockSource is kept, and invalid blocks cause asynchronous "reject"
messages and banning (if necessary).
Previously CreateNewBlock() didn't take into account the fact that
IsFinalTx() without any arguments tests if the transaction is considered
final in the *current* block, when both those functions really needed to
know if the transaction would be final in the *next* block.
Additionally the UI had a similar misunderstanding.
Also adds some basic tests to check that CreateNewBlock() is in fact
mining nLockTime-using transactions correctly.
Thanks to Wladimir J. van der Laan for rebase.
Unit tests would fail if compiled with -DDEBUG_LOCKORDER (AssertLockHeld()
would fail; AssertLockHeld() relies on the DEBUG_LOCKORDER code to keep
track of locks held).
Fixed by LOCK'ing the wallet mutex in the unit tests that manipulate the
wallet.
After the tinyformat switch sprintf() family functions support passing
actual std::string objects.
Remove unnecessary c_str calls (236 of them) in logging and formatting.

Currently it is only possible to use `walletpassphrase` to unlock the
wallet when bitcoin is started in server mode.
Almost everything that manipulates the wallet in the RPC console
needs the wallet to be unlocked and is thus unusable without -server.
This is pretty unintuitive to me, and I'm sure it's even more confusing
to users.
Solve this with a very minimal change: by making the GUI start a
dummy RPC thread just to handle timeouts.
- as a proxy set via GUI can be overridden via -proxy, directly query the
core to get active proxy
- give a warning, if active proxy is not SOCKS5 (needs to be SOCKS5 for
the Qt networking code to work)
- also remove an obsolete connect() call from optionsdialog.cpp and a
reference to Bitcoin-Qt (now just GUI)
Instead of using the boost provided by Ubuntu 12.04, build our own
dependency like we do for Windows.
This allows using a much newer version (1.55 versus 1.46) as well as
building with `-fPIC` so that `-pie` can be used in the x86-64 build.
Build only the mt-s (multithreaded, static runtime link)
variant of the library.
This cuts the build time in half.
Also prevent unpacked boost from ending up in output directory,
checking and hashing all the source files as output files this
takes a lot of time and is pointless.

Also hide the debug console during shutdown as it is useless without
a core to connect to.
Remove the need for global references `guiref` and
`splashref` by making the BitcoinGUI and SplashScreen
classes register for the UI interface signals themselves.
Move AppInit2 and Shutdown to a thread.
This allows a more responsive splash screen, prevents 'process does not respond'
messages from the window system and will allow for showing a user friendly
window while shutting down.

Since we're now properly linking against static plugins for qt binaries,
we need to ensure that they're Imported properly.
Without these Imports, the linker drops some of the unused linked libs, causing
undefined symbols in QtCore.
At least Debian/Ubuntu use 'qtchooser' for switching between qt4/qt5 binaries.
It is a wrapper for all qt tools, and calls the named tool of the default
version unless overridden by the -qt= option or QT_SELECT environment variable.
QT_SELECT is set by configure once the qt version has been chosen.
Take for example, moc.
$ which moc
/usr/bin/moc
$ ls -go /usr/bin/moc
lrwxrwxrwx 1 9 Jul 3 21:33 /usr/bin/moc -> qtchooser
$ qtchooser -print-env
QT_SELECT="default"
QTTOOLDIR="/usr/lib/x86_64-linux-gnu/qt4/bin"
QTLIBDIR="/usr/lib/x86_64-linux-gnu"
$ QT_SELECT=qt5 qtchooser -print-env
QT_SELECT="qt5"
QTTOOLDIR="/usr/lib/x86_64-linux-gnu/qt5/bin"
QTLIBDIR="/usr/lib/x86_64-linux-gnu"
$ moc -v
Qt Meta Object Compiler version 63 (Qt 4.8.4)
$ QT_SELECT=qt5 moc -v
Qt Meta Object Compiler version 67 (Qt 5.0.1)
This should be harmless elsewhere.
In the win32 gitian descriptor the C*FLAGS are being overridden on
`configure`, which causes the built-in optimization flags to be removed.
Add `-O2` manually (but not `-g` as we're not doing anything with the

Improves performance of win32 gitian builds.
As a bonus, fixes issue #3497.
- remove unused and unmentioned file notsynced.png (we use an animation
for this)
- add missing coincontroldialog.ui to bitcoin-qt.pro
- also unify formating in assets-attribution.md
Update current translations, and add new languages:
- es_MX: Spanish (Mexico)
- pam: Kapampangan
Also update translation process for autoconf-based build system.
- add new options for database cache and script verification threads
- add label which displays options that are overridden by command-line
parameters
- proxy settings are not applied on-the-fly anymore and require a client
restart (ApplyProxySettings() was removed and was not working very well
anyway)
- re-work options reset and require a client shutdown (as it is much
easier to do it this way without having to mess with what can be changed
on-the-fly and what needs a restart anyway)
- options reset now writes default values for every single option
- when changing an option which requires a client restart display a 10
second warning message in statusLabel (via a QTimer)
- when applying the changes via ok change that to a persistent message,
which is displayed even after closing optionsdialog and re-open it, when
no client restart was made
- remove dialog boxes used when changing language or proxy settings
- add setRestartRequired() and isRestartRequired() to OptionsModel and
use the set function when updating options to signal OptionsDialog
when a restart is needed
- resize optionsdialog a little and add some min sizes for certain GUI
elements
- remove apply button from optionsdialog
- save and restore optionsdialog window position
- update nTransactionFee in QSettings with a set -paytxfee value when
opening optionsdialog (I'm not sure about this yet, perhaps revert to
not updating QSettings and just display current -paytxfee value in
optionsdialog.)

Splits and documents the phases:
1. Parse command-line options. These take precedence over anything else.
2. Basic Qt initialization (not dependent on parameters or configuration)
3. Application identification
4. Initialization of translations
5. Now that settings and translations are available, ask user for data directory
6. Determine availability of data directory and parse bitcoin.conf
7. URI IPC sending
8. Main GUI initialization
Splits command line parsing logic from ipcSendCommandLine into
ipcParseCommandLine, as isTestNet() can only be overridden in the early
stages before choosing a data directory. Sending however needs to happen
after choosing a data directory.
Pressing <tab> after entering a label now brings the focus to the
address entry, instead of the row of buttons. In my experience this
is more useful, as I usually want to paste an address after
entering the label.
The buttons are mostly useless anyway:
- Choosing a previously used address should be discouraged
- When I'm already using the keyboard the 'paste address' button is
useless - just use the Ctrl-V. Maybe it would be an idea to remove it
completely
- I usually don't want to remove the entry I'm typing now! So makes
sense to have it at the end of the tab chain.
Unit tests for uint256.h. The file uint160_tests.cpp is no longer
needed. The ad-hoc tests which were in uint256.h are also no longer
needed. The new tests achieve 100% coverage.
The function Get64(.) has a bug in case the width is not divisible by 64.
Since it is only ever used as Get64(0) this simply changes it to this
special case. Additionally, an assert is added, and a cast to prevent
a compiler error.
Add a function `WaitBlocks` to wait for blocks to propagate to all three

Allow running bitcoind without server.
- Default to -server mode (of course) for bitcoind with SoftSetBoolArg
- Remove fForceServer argument from AppInit2
- Move fDaemon to a static variable in bitcoind
- re-work change address handling so that default is CNoDestination(),
until a verified and known change address was entered (easier code flow)
- add a missing NULL pointer check for adresstablemodel
- add a missing text when opening coin control address selection for
priority and ensure the label is black
- add a missing . at the end of a sentence

The current transaction loading code is not exception safe.
An exception during deserialization causes an empty transaction
to be left behind in the wallet.
Fix this by building the transaction separately and adding
it only to the wallet at the end.
Fixes#3333.
Seperate out the wallet options in HelpMessage, and
don't show them if compiled with --disable-wallet.
Also add documentation for `-disablewallet` option.
0205abd Improve unit test code not to compare with explanatory messages for each platform. Instead, use have an exception object to check if the string returned by what() on the raised exception matches the string returned by what() on the expected exception instance. This way, we do not need to list all different possible explanatory strings for different platforms in the test code, and make it simple. (The idea is by Cory Fields.) (Kangmo)

Before the fix, there were 6 errors such as :
serialize_tests.cpp:77: error in "noncanonical": incorrect exception std::ios_base::failure is caught
It turns out that ex.what() returns following string instead of "non-canonical ReadCompactSize()"
"non-canonical ReadCompactSize(): unspecified iostream_category error"
After the fix, unit test passed.
The test ran using Apple LLVM v5.0 on OSX 10.9 and the unit test error happened because of different error messages by different compilers.

`-logtodebugger` is a strange, obscure, WIN32-only (mostly MSVC) thing.
Let's clean up the options a bit get rid of it.
test_bitcoin was using fLogToDebugger as a way to prevent logging to
debug.log. For this, add a boolean (not exposed as option) fLogToDebugLog that
defaults to true and is disabled in the tests.
ThreadSafeAskFee is effectively unused. It is only called
when the fAskFee parameter on SendMoney or SendMoneyToDestination
is true, which never happens. Remove it.
`getinfo` is a general info method which shows information
from multiple sources, it doesn't belong in rpcnet.cpp or
any of the other current RPC implementation files.
Only messages for now, executable names and other file names
can be changed later if necessary and safe.
Do not do an all-sweeping change. Some occurences of Bitcoin-Qt need to
be kept:
- Applicationname: this is used to determine the registry entry names,
we don't want to lose settings over a silly name change.
- Where it refers to the executable name instead of the product name.

Solution is to use the raw boost mutex instead of a CCriticalSection.
- replaces a pwalletMain->IsLocked() check
- in keypoolrefill init kpSize to 0 as we have the logic to determine max
kpSize in pwalletMain->TopUpKeyPool() anyway
- cleanup Info.plist.in and specify high DPI mode enable command as per
http://blog.qt.digia.com/blog/2013/04/25/retina-display-support-for-mac-os-ios-and-x11/
- move setting of QApplication::setAttribute() to bitcoin.cpp and add
attribute for enabling use of high DPI pixmaps for Qt >= 5.1
- add missing setWindowTitle() on Mac
- cleanup Mac / non-Mac setup in bitcoingui.cpp
Use a fixed script instead of a CReserveKey from the wallet.
This does not affect the functionality or result of the tests as they never
check the state of the wallet in the first place.
The following mining-related RPC calls don't use the wallet:
- getnetworkhashps
- getmininginfo
- getblocktemplate
- submitblock
Enable them when compiling with --disable-wallet.

- make eventFilter() private and pass events on to QObject::eventFilter()
instead of just returning false
- re-work paymentservertest.cpp to correctly handle the event test
after the above change (rewrite test_main to allow usage of
QCoreApplication:: in the tests)
- delete socket when we were unable to connect in ipcSendCommandLine()
- show a message to the user if we fail to start-up (instead of just a
debug.log entry)
- misc small comment changes
Versions of bitcoin before 0.8.6 have a bug that inserted
empty transactions into the vtxPrev in the wallet, which will cause the node to be
banned when retransmitted, hence add a check for !tx.vin.empty()
before RelayTransaction.
CWalletTx::AddSupportingTransactions() was adding empty transaction
to vtxPrev in some cases. Skip over these.
Part one of the solution to #3190. This prevents invalid vtxPrev from
entering the wallet, but not current ones being transmitted.
This was a leftover from the times in which
peers.dat depended in BDB.
Other functions in db.cpp still depend on BerkelyDB,
to be able to compile without BDB this (small)
functionality needs to be moved to another file.
Where to place `getinfo` is a difficult issue
as it shows information from the wallet, net and
block chain. However, I moved it out of rpcwallet
as the command needs also to be available without
wallet.
Use deleteLater() instead of delete, as it is not allowed
to delete widgets directly in an event handler.
Should solve the MacOSX random crashes on send with coincontrol.
Remove unnecessary dependencies for bitcoin-cli
(leveldb, berkelydb, wallet, RPC server)
Build system changes:
- split libbitcoin.a into libbitcoin_common.a, libbitcoin_server.a and
libbitcoin_cli.a
Code changes (movement only):
- split up HelpMessage into HelpMessage in init.cpp and HelpMessageCli
in rpcclient.cpp
- move uiInterface from init.cpp to util.cpp
There were quite a few places where assert() was used with side effects,
making operation with NDEBUG non-functional. This commit fixes all the
cases I know about, but also adds an #error on NDEBUG because the code
is untested without assertions and may still have vulnerabilities if
used without assert.
- remove style sheets from ui files and use Qt attributes instead
- make some more strings untranslatable, to make life for translators
easier
- split up long tooltips an rework the texts a little
- remove monospace labels from sendcoinsdialog also
- use a validated line edit for the change address
- add a tooltip to change address switch
- ensure we have a valid change address in
CoinControlDialog::coinControl->destChange or just CNoDestination()
- some small ui file changes
bae6c7e Fix a rare crash on Mac OS X, by removing a setFocus on the payTo field that was not necessary, as the field still receives focus without it. (Ryan Niebur)
This dead code can be resurrected from git history if
transaction replacement is ever implemented. Keeping
dead code in the source is a bad idea, because it implies
it was tested and worked at some point, which is not true.
The SelectParamsFromCommandLine call was missing in bitcoin-cli,
which caused `-testnet` and `-regtest` to be ignored. Add this
call just like in bitcoind.cpp.
Split bitcoinrpc up into
- rpcserver: bitcoind RPC server
- rpcclient: bitcoin-cli RPC client
- rpcprotocol: shared common HTTP/JSON-RPC protocol code
One step towards making bitcoin-cli independent from the rest
of the code, and thus a smaller executable that doesn't have to
be linked against leveldb.
This commit only does code movement, there are no functional changes.
qa/rpc-tests/wallet.sh runs a three-node -regtest network,
generates a fresh blockchain, and then exercises basic wallet
sending/receiving functionality using command-line RPC.
The last fee drop was by 5x (from 50k satoshis to 10k satoshis)
in the 0.8.2 release which was about 6 months ago.
The current fee is (assuming a $500 exchange rate) about 5 dollar
cents. The new fee after this patch is 0.5 cents.
Miners who prefer the higher fees are obviously still able to
use the command line flags to override this setting. Miners who
choose to create smaller blocks will select the highest-fee paying
transactions anyway.
This would hopefully be the last manual adjustment ever required
before floating fees become normal.
After discussing with BlueMatt, this appears to be harmless in its
current state since it's always set before it's used. Initialize it
anyway for readability and future safety.
- this adds a delete button for insecure and secure payment requests in
the sendcoins dialog
- it also enables the delete button even for single and empty entries, as
this is much easier to handle and doesn't need to special case single
entries
- big parts of the ui file were changed, because I copied the delete
button and had to delete the layout too and created it from scratch
(which seems to cleanup the rows and colums in the layout also, which is
nice IMHO)
I'm writing some wallet regression tests using -regtest mode, and
need to generate an initial multi-hundred-block chain. Repeatedly
calling setgenerate to generate one block is slow and doesn't
work properly, because block creation happens asynchronously.
This adds two features to setgenerate in -regtest mode:
1) Instead of being interpreted as number of threads to start, the
third argument is the number of blocks to generate.
2) setgenerate will not return until the block creation threads
have created the requested number of blocks.
When building from tarball (i.g. not from git source tree or when git
is not available) `genbuild.sh` write undefined $TIME to "build/build.h".
Even worse, when TIME is set in the environment then its value
is written instead of a date.
For me this change fixed FTBFS which I got because I had
TIME enviroment variable set with format for time(1) utility.
Keep a list of requested payments in the Receive tab so that a user can
recall previously created requests after closing their windows.
Currently this list is not stored between bitcoin-qt sessions. This can
be implemented later, but it is not clear where it should be stored as
I don't think it belongs in the wallet (maybe in QSettings?)
- Fixed cut-and-paste error.
- See http://savannah.gnu.org/patch/?7576 for further details.
- Use 'ls -r' rather than non-portable tool 'tac'.
- Simplify filepattern in ls expression so dylib (on OSX) are also detected.
- add missing license headers
- make compatible with Qt5
- enforce header cleanup style
- small code style cleanups
- rename Coin Control dialog into Coin Control Address Selection
- use default font for the windows labels (no monospace)
Make users accustomed to the other subdivision units (mBTC, muBTC)
by showing the total amount in all units in the confirmation dialog.
This was recently raised on the mailing list and could be a preparation
for switching over the default unit eventually.
I was merging change this every time before generation of
the doxygen developer docs (https://dev.visucore.com/bitcoin/doxygen/)
but there's no reason why it can't just be merged upstream.
We already have the exact same funtionality in /contrib/bitrpc/bitrpc.py
If we really do need standalone scripts, then I'll write something to
pull it from that file, rather than having duplicate code.
Forgot to remove wallet tools from index.
Wallet Tools Follow Up Info
- remove default value for parent variable in dialogs, which should appear
centered over main GUI and pass appropriate value
- add some addition NULL pointer checks
Adds three new languages:
- de_AT: German (Austria)
- gl: Galician
- sl_SI: Slovenian (Slovenia)
Updates many others.
Thanks to the translators contributing on Transifex!
Don't require lupdate to build with Qt. Like xgettext it is only
needed to update translations, not for normal builds.
This fixes the gitian build (broken by fcfbf547d).
Based on the proposal, update the help message of rpc methods
- strings arguments are in double quotes rather than square brackets
- numeric arguments have no quotes (and no default value)
- optional parameters are surrounded by round brackets
- json arguments are strings but don't use double quotes
Added 3 sections for the details
- Arguments: lists each argument, it's type, required or not, a default, and a description
- Result: The method result, with json format if applicable, type, and a description
- Examples: examples calls using bitcoin-cli and curl for json rpc call
Problems
- maybe this is too verbose
- lines might be too long
- description are not good or complete
- examples may be too much
- remove explicit init of netManager as this is done in the constructor
anyway
- move initNetManager() call to uiReady(), which removes an assert() and
allows us to use message() in initNetManager() (currently unused but
could be necessary because of proxy related messages)
- make initNetManager() private
- update paymentservertests.cpp
I regenerated the alert test data; now alerts are tested
against a protocol version way above the current protocol
version.
So we won't have to regenerate them every time we bump
PROTOCOL_VERSION in the future.
Use misc methods of avoiding unnecesary header includes.
Replace int typedefs with int##_t from stdint.h.
Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h.
Normalize QT_VERSION ifs where possible.
Resolve some indirect dependencies as direct ones.
Remove extern declarations from .cpp files.
- rework window title to not include Bitcoin - in front, as no other
dialog does this
- favor a connect() call over an own function for clearing the traffic
graph
- write monospace lowercase (seems to be correct after some web search)

As block index entries have a flag for marking invalid blocks, the
'best invalid work' information can be derived from there. In addition,
remove the global from main.h
- this shows insecure (unsecured) payment requests in a new yellowish
colored UI (based on the secure payment request UI) instead of our
normal payment UI
- allows us to receive paymentACK messages for insecure payment requests
- allows us to handle expirations for insecure payment request
- changed walletmodel, so that all types of payment requests don't touch
the addressbook
- add new processSendCoinsReturn() function, which parses the
status of WalletModel::SendCoinsReturn and generates a pair consisting
of a message and message flags
- result is we only need one emit message() call
- this change ensures that the GUI is shown for warnings/errors in
sendcoinsdialog, because of message() taking care of that for modal
messages
- changes 2 warning message into error messages and removed "Error:"
in front of the actual error message string
- re-work -debug help message text
- make -debug log every debugging information again (even all categories)
- remove unneeded fDebug checks in front of LogPrint()/qDebug(), as that
check is done in LogPrintf() when category is != NULL (true for all
LogPrint() calls
- remove fDebug ONLY in code which is NOT performance-critical
- harmonize addrman category name
- deprecate -debugnet usage, should be used via -debug=net and remove the
corresponding global
Changed CDataStream::GetAndClear() to use the most obvious
get get and clear instead of a tricky swap().
Added a unit test for CDataStream insert/erase/GetAndClear.
Note: GetAndClear() is not performance critical, it is used only
by the send-a-message-to-the-network code. Bug was not noticed
before now because the send-a-message code never erased from the
stream.
Instead of explicitly testing for the presence of any output, and
dealing with this case specially, just interpret it as an empty
CCoins.
The case previously caught using the HaveCoins check, is now handled
by the generic outs != outsBlock test.
class template base_uint had its own private lookup table.
This is saving 256 bytes per instantiation.
The result is not spectacular as bitcoin-qt has only shrinked of
about 1Kb but it is still valid improvement.
Also, I have replaced a for loop with a memset() call.
Made CBigNum::SetHex() use the new HexDigit() function.

Use proper signals everywhere.
Removes the need to store a pointer to the BitcoinGUI object in
the walletview.
Also removes the interdependence between setWalletModel / setBitcoinGUI.
* Use the latest version, with limited memory usage, and path to
on-disk db (try mouting qa/tmp on a tmpfs)\
* enable -debug=net
* re-enable BitcoindComparisonTool in pull-tester
- remove 2 unneeded windowTitle attributes, which bloat our translations
- cleanup some unneeded .cpp/.h includes and class usages
- use a more generic string for clearing sendcoinsdialog and
requestpaymentdialog
- edit 2 strings in BitcoinGUI and replace "edit" with "show" as this
seems more clear in the context where it is used
This seems to cause problems on recent clang, and looks totally
redundant and unused.
The const_iterator version is identical to the vector::const_iterator
one (which is a typedef thereof). Marking it private (instead of
removing) compiles fine, so this version is effectively unused even.
This required some code movement (what was CWalletTx::AcceptToMemoryPool
doing in main?), and adding a few explicit includes that used to be
implicit through init.h.
INIT_PROTO_VERSION is the initial version, after a succesful version/verack it is increased to a negotiated version.
MIN_PEER_PROTO_VERSION could be a different value to disconnect from peers older than a specified version.
Changes the response to the 'mempool' command so that if
the memory pool has more than MAX_INV_SZ transactions (50,000)
it will respond with multiple 'inv' messages.
They're supposed to be children of the walletview, and are added with
addWidget later on.
Inconsequential change because the object passed was already 0.
- changes some strings that were forgotton or made no sense in the conext
they are used
- remove an orphan file from the qt project file
- revert a small change in signverifymessagedialog.ui
- guard #include "bitcoin-config.h" with #if defined(HAVE_CONFIG_H)
- remove windowTitle from addressbookpage.ui
- this allows us to use emit message() over MessageBox:: or gui->message()
calls in sendcoinsdialog and walletview
- move main handlePaymentRequest() functionality back to BitcoinGUI
- move a showNormalIfMinimized() before gotoSendCoinsPage()
- We no longer have an address book, but "address lists", update message
accordingly
- Add tooltips here and there
- Clarify text on buttons
- add Copy Address button to receive request dialog
- add new slot handlePaymentACK() to paymentserver, which handles
paymentACK messages (currently we just display them)
- make paymentACK message a modal information dialog
- change some QObject::tr() to just tr()
- clarify the processPaymentRequest() error, when IsDust()
- small string change to prevent a tripple + usage with QString
Previously bitcoin-qt's -debug transaction info was showing CTxOut([error])
It is valid for a scriptPubKey to be any size, for example simply
OP_RETURN is valid and can be used to destroy a TXOUT to mining fees.
- fix crash with walletpassphrase by checking if RPC server is running and
give a friendly error message how to fix this (fixes#3100)
- add 3 new RPCErrorCodes RPC_SERVER_NOT_STARTED, RPC_NODE_ALREADY_ADDED
and RCP_NODE_NOT_ADDED (I checked the source to not use a number already
in use for RPC_SERVER_NOT_STARTED)
- use the new codes where needed / missing
- add missing use of RPC_INVALID_PARAMETER
Just-in-case sanity test for JSON spirit and AmountFromValue.
Also update rpc_format_monetary_values test to use ValueFromAmount,
so that ValueFromAmount is also tested.
Simplifies the dialog (makes it look less crowded) as well
as the code and makes it possible to copy multiple fields at once.
Also format bitcoin URI as URI, add copy button for URI.
Also update URI parsing to fill in this field.
Note that the message is not currently used in any way with the client.
It should be stored with the transaction.
These no longer make sense in the new workflow. It's less
clicks to reach sign/verify message from the menu. And sending
from the address book is one kind of automatic address reuse
we're trying to avoid.
The existing CNode::addrLocal member is revealed to the user,
as an address string, similar to the existing "addr" field.
Instead of showing garbage or empty string,
it simply will not appear in the output if local address not known yet.
This adds an executable `bitcoin-rpc` that only serves as a Bitcoin RPC
client.
The commit does not remove RPC functionality from the `bitcoind` yet,
this functionality should be deprecated but is left for a later version
to give users some time to switch.
This ensures the allocator is ready no matter when it's needed (as
some STL implementations allocate in constructors -- i.e., MSVC's STL
in debug builds).
Using boost::call_once to guarantee thread-safe static initialization.
Adding some comments describing why the change was made.
Addressing deinitialization of the LockedPageManager object
by initializing it in a local static initializer and adding
an assert in the base's destructor.
Selecting the button for a pages was going through bitcoingui->walletframe->walletview->bitcoingui.
Because of this, the actions for the pages had to be exposed on the BitcoinGUI object.
- rename reportError() into message() to be in line with our default
message() signal/slot naming (and can be used for all types of messages)
- rename some QStrings to not collide with message() function
- add a missing message for malformed URIs that IS also used in BitcoinGUI
- fix / extend some comments and misc style fixes
There were too many levels of indirection here, and the functionality of
walletframe and walletstack can easily be merged. This commit
merges the two which cuts a lot of lines of boilerplate code.
- this extends the accepted ciphersuites with TLSv1.2 ones
- also removes !AH, as I could not find documentation on it and the change
did not result in a changed ciphersuite list (checked via openssl
ciphers -v)
- closes#3096 (which also contains more details)
SendMessages() tries to acquire a cs_main lock now, but this isn't nessecary
for much of its functionality. Move those parts out of the locked section,
so they can always be performed, and we hold cs_main for a shorter time.
This removes a few unused CBlockLocator methods, and moves the
construction and fork-finding logic to CChain (which can do these
more efficiently, as it has a height-indexable chain available).
It also makes CBlockLocator independent from the validation code.
Seems like there are a lot of advertised testnet HS nodes that
don't actually work. Lack of the testnet port on the example
HS config might be one reason.
971bb3e Added ping time measurement. New RPC "ping" command to request ping. Implemented "pong" message handler. New "pingtime" field in getpeerinfo, to provide results to user. New "pingwait" field, to show pings still in flight, to better see newly lagging peers. (Josh Lehan)
- I observed a massive amount of redefinition warnings after #3071, which
are silenced by this patch
- uses the same style as we do in other places, where we define _WIN32_WINNT
- make processPaymentRequest() use our own HTML-escaping function from
GUIUtil
- make string "application/bitcoin-payment" a constant (below similar
constant strings in the .cpp file)
- clear(): clear all UI elements (for secure and insecure payments)
- setValue(): only modify UI elements, which need to be set (for secure
or insecure payments)
Re-organize the pull-tester scripts a bit.
And disables running the blockchain tester, it is not working properly

Create an allocators.cpp, and move all of the #ifdef WIN32
code and the #include of windows.h into it.
Two motives for this cleanup:
1. I'm getting a weird error in windows.h in my smartfee branch.
2. allocators.h is included (indirectly) just about everywhere, so
this should speed up Windows compiles quite a lot.

- added a comment for the if (!fRet) case
- when closing the client with an open debug window, that window could
become stuck/unsuable (it was still shown wherea the main window was
hidden already)
- fix this by hiding the debug window, when quitting the the client
Changes the maximum size of a free transaction that will be created
from 10,000 bytes to 1,000 bytes.
The idea behind this change is to make the free transaction area
available to a greater number of people; with the default 27K-per-block,
just three very-large very-high-priority transactions could fill the space.
Remove the (relay/mempool) rule that all outputs of free transactions
must be greater than 0.01 XBT. Dust spam is now taken care of by making
dusty outputs non-standard.
New RPC "ping" command to request ping.
Implemented "pong" message handler.
New "pingtime" field in getpeerinfo, to provide results to user.
New "pingwait" field, to show pings still in flight, to better see newly lagging peers.
This commit adds a step, which is to git checkout the version to be
built. This ensures that the gitian-descriptors for said version will be
the correct ones. In addition, it updates the links for several
dependencies, where the previously existing links were dead.
- remove some unneeded translatable strings from sendcoinsentry.ui file and
rename some elements for better readability
- optimize string prorcessing in SendCoinsDialog::on_sendButton_clicked()
- make all UI labels for secure payments plain text and move the settings
to sendcoinsentry.ui file
- remove unneeded button and default button definiton from warning message
boxes
- remove fixed font-size when sending coins to an address with label and
use monospace font for addresses

Removing wine as a win32 build dep is beneficial to fixing Gitian LXC,
which would enable many more people to join in the gitian.sigs process
by being able to build with a linux VM instead of a virt capable host.
The final revision of PR 3029 incorporated a review suggestion of replacing

minimal changes necessary to fix the qt-win32.yml build.

- small code formatting changes
Instead of building a full copy of a CTransaction being signed, and
then modifying bits and pieces until its fits the form necessary
for computing the signature hash, use a wrapper serializer that
only serializes the necessary bits on-the-fly.
This makes it easier to see which data is actually being hash,
reduces load on the heap, and also marginally improves performances
(around 3-4us/sigcheck here). The performance improvements are much
larger for large transactions, though.
The old implementation of SignatureHash is moved to a unit tests,
to test whether the old and new algorithm result in the same value
for randomly-constructed transactions.

1. Check in CPPFLAGS, as a user might have manually passed a path to check.
2. Ensure the value is not empty before setting BDB_CPPFLAGS to "-I value"
This changes the priority calculation to not include the size of per-txin
data including up to 110 bytes of scriptsig so that transactions which
sweep up extra UTXO don't lose priority relative to ones that don't.
I'd toyed with some other variations, but it seems like any formulation
which results in an incentive stronger than making them not count will
sometimes create incentives to add extra outputs so that you have
extra inputs to consume later. The maximum credit is limited so that
users don't lose the disincentive to stuff random data in their
transactions, the limit of 110 is based on the size of a P2SH
redemption with a compressed public key.
This shouldn't need a staged deployment because the priority is not
used as a relay criteria, only a mining criteria.
This change moves test data into the binaries rather than reading them from
the disk at runtime.
Advantages:
- Tests become distributable
- Cross-compile friendly. Build on one machine and execute in an arbitrary
location on another.
- Easier testing for backports. Users can verify that tests pass without having
to track down corresponding test data.
- More trustworthy test results and easier quality assurance as tests make
fewer assumptions about their environment.
- Tests could theoretically run at client/daemon startup and exit on failure.
Disadvantages:
- Required 'hexdump' build-dependency. This is a standard bsd tool that should
be usable everywhere. It is likely already installed on all build-machines.
- Tests can no longer be fudged after build by altering test-data.
libleveldb.a and libmemenv.a should be able to build in parallel, but in
practice calling the leveldb makefile ends up rewriting build_config.mk. If
one target tries to build while the other is halfway through writing the
.mk, the make ends up in an undefined state.
Fix that by making one depend on the other. This also reorders the variables
to be passed by param rather than via the environment, and combines the targets
into a single rule to avoid needless duplication.
As we'd previously learned, OSX's fsync is a data eating lie.
Since 0.8.4 we're still getting some reports of disk corruption on
OSX but now all of it looks like the block files have gotten out of
sync with the database. It turns out that we were still using fsync()
on the block files, so this isn't surprising.
- ensure message boxes are shown in center of our main window, not
centered on the users desktop
- always prefer user supplied titles for message boxes over the functions
defaults (fixes a bug, where transaction info messages did not contain
information, if it was incoming or outgoing)
- rename URL into URI in paymentserver where correct
- add some missing Qt-coding-stuff in paymentserver
- change QSpinBox to QLineEdit as base for BitcoinAmountField in .ui files
(as this is the result when converting the BAF back into base)
- remove some c_str() and replace with QString::fromStdString()
- remove several new-lines
- remove unneeded spaces
- indentation fixes
This also makes negative transaction versions non-standard.
This avoids an issue triggered in block 256818 where transactions with
negative version numbers were incorrectly serialized into the UTXO set.
On restart nodes detect the inconsistency and refuse to start so long as
a block with these transactions is inside the self-consistency check
window, logging "coin database inconsistencies found". The software
recommends reindexing, but reindexing does not correct the problem.
This should be fixed by changing the chainstate serialization, but
working around it seems harmless for now because the version is not
used by any network rule currently.
A patch free workaround is to start with -checklevel=2 which skips
the consistency checks, but the IsStandard change is important for
miners in order to protect unpatched nodes.
I've seen users confused multiple times thinking they
should be using -tor to set their tor proxy and then
finding in horror that they were still connecting to
the IPv4 internet.
Even Jeff guesses wrong about what the knob does, so
I think we should rename it. This leaves the old
knob working, we can pull it out completely in a
later release.
- prepend "Bitcoin-Qt" in front of debug.log entries, which come from Qt
- move DebugMessageHandler installation upwards to the event handler
installation, which fits much better
Correctly use the purpose of addresses that are added after the start
of the client. Addresses with purpose "refund" and "change" should not
be visible in the GUI. This is now handled correctly.
- extend PaymentServer with setOptionsModel() and rework initNetManager()
to make use of that
- fix all other places in the code to use display unit from options and no
hard-coded unit
There have been several incidents where mainnet experimentation with
raw transactions resulted in insane fees. This is hard to prevent
in the raw transaction api because the inputs may not be known.
Since sending doesn't work if the inputs aren't known, we can catch
it there.
This rejects fees > than 10000 * nMinRelayTxFee or 1 BTC with the
defaults and can be overridden with a bool at the rpc.
We're not seeing large reorgs that would justify waiting a large
amount past the rule required maturity, and the extra three
hours is just a nuisance. Take one more block to at least give
the 100th block time to propagate.
Seems it was forgotten about when IsPushOnly() and the unittests were
written. A particular oddity is that OP_RESERVED doesn't count towards
the >201 opcode limit unlike every other named opcode.
getblocktemplate only uses certain portions of the coinbase transaction,
notably ignoring the coinbase TX output entirely.
Use CreateNewBlock() rather than CreateNewBlockWithKey(), eliminating
the needless key passing.
Should be zero behavior changes.
With an encrypted wallet the GUI was prompting for a passphrase every time
the user requested a new address. This is unnecessary, increases the
exposure to keyboard sniffers, and discourages using fresh addresses for
every transaction.
Instead only prompt for a passphrase when the keypool runs out, also call
the new address function with the flag that prevents reuse.
Thanks to AlexNagy on IRC for pointing this out and who wouldn't take any
lip from a curmudgeonly developer and insisted on what he knew to be true.
WalletView:
- add new signal showNormalIfMinimized()
- emit the new signal in handleURI() to fix a bug, preventing the main
window to show up when using bitcoin: URIs
WalletStack:
- connect the showNormalIfMinimized() signal from WalletView with the
showNormalIfMinimized() slot in BitcoinGUI
- rework setCurrentWallet() to return a bool
- add check for valid walletModel in addWallet()
- add missing gui attribute initialisation in constructor
WalletFrame:
- remove unused or unneded class attributes gui and clientModel
- add a check for valid clientModel in setClientModel()
General:
- small code formatting changes
Add support for a Payment Protocol to Bitcoin-Qt.
Payment messages are protocol-buffer encoded and communicated over
http(s), so this adds a dependency on the Google protocol buffer
library, and requires Qt with OpenSSL support.
- move SelectParamsFromCommandLine() from init.cpp to bitcoin.cpp to allow
to use TestNet() for Bitcoin-Qt instead of GetBoolArg("-testnet", false)
- change order in bitcoind.cpp to match bitcoin.cpp functionality
- hamonize error message strings for missing datadir and failing
SelectParamsFromCommandLine() in bitcoin.cpp and bitcoind.cpp
- use TestNet() call in splashscreen.cpp
Straight refactor, so mapAddressBook stores a CAddressBookData
(which just contains a std::string) instead of a std::string.
Preparation for payment protocol work, which will add the notion
of refund addresses to the address book.
Replaces the validation check for "amount == 0" with an isDust check,
so very small output amounts are caught before the wallet
is unlocked, a transaction is created, etc.
- update translation master files
- include current translations from Transifex
- add several new languages
- fix a bug in bitcoin.qrc, which prevents some languages from beeing used
(wrong file extension .ts instead of .qm was used)

This reduces a peer's ability to attack network resources by
using a full bloom filter, but without reducing the usability
of bloom filters. It sets a default match everything filter
for peers and it generalizes a prior optimization to
cover more cases.

To fix a minor malleability found by Sergio Lerner (reported here:
https://bitcointalk.org/index.php?topic=8392.msg1245898#msg1245898)
The problem is that if (R,S) is a valid ECDSA signature for a given
message and public key, (R,-S) is also valid. Modulo N (the order
of the secp256k1 curve), this means that both (R,S) and (R,N-S) are
valid. Given that N is odd, S and N-S have a different lowest bit.
We solve the problem by forcing signatures to have an even S value,
excluding one of the alternatives.
This commit just changes the signing code to always produce even S
values, and adds a verification mode to check it. This code is not
enabled anywhere yet. Existing tests in key_tests.cpp verify that
the produced signatures are still valid.
The length of vectors, maps, sets, etc are serialized using
Write/ReadCompactSize -- which, unfortunately, do not use a
unique encoding.
So deserializing and then re-serializing a transaction (for example)
can give you different bits than you started with. That doesn't
cause any problems that we are aware of, but it is exactly the type
of subtle mismatch that can lead to exploits.
With this pull, reading a non-canonical CompactSize throws an
exception, which means nodes will ignore 'tx' or 'block' or
other messages that are not properly encoded.
Please check my logic... but this change is safe with respect to
causing a network split. Old clients that receive
non-canonically-encoded transactions or blocks deserialize
them into CTransaction/CBlock structures in memory, and then
re-serialize them before relaying them to peers.
And please check my logic with respect to causing a blockchain
split: there are no CompactSize fields in the block header, so
the block hash is always canonical. The merkle root in the block
header is computed on a vector<CTransaction>, so
any non-canonical encoding of the transactions in 'tx' or 'block'
messages is erased as they are read into memory by old clients,
and does not affect the block hash. And, as noted above, old
clients re-serialize (with canonical encoding) 'tx' and 'block'
messages before relaying to peers.
Fixes issue#2838; this is a tweaked version of pull#2845 that
should not leak the length of the password and is more generic,
in case we run into other situations where we need
timing-attack-resistant comparisons.
Orphan transactions were stored as a CDataStream pointer;
this changes the mapOrphanTransactions data structures to
store orphans as a CTransaction.
This also fixes CVE-2013-4627 by always re-serializing
transactions before relaying them.
- move the code for saving and restoring window positions from BitcoinGUI
to GUIUtil, make it more generic and also use it for saving/restoring
debug window positions
- it was possible to trigger an infinite loop in FreespaceChecker::check() by
simply removing the drive letter on Windows (which leads to an infinite
loop in the FreespaceChecker thread)
- this was caused by not checking if we make progress with
parentDir.parent_path()
- remove an unneded include for mswsock.h as we use winsock2.h anyway
- move typedef u_int SOCKET; into the #ifndef WIN32 part
- remove typedef int socklen_t; as this is defined in ws2tcpip.h
- fixes src\net.cpp:1601: Error:invalid conversion from 'void*' to
'const char*' [-fpermissive] in a setsockopt() call on Win32 that was
found by using MinGW 4.8.1 compiler suite
The key refactor changed the way unencrypted private keys with compressed
public key are stored in the wallet. Apparently older versions relied on
this to verify the correctness of stored keys.
Note that earlier pre-release versions do risk creating wallets that can
not be opened by 0.8.3 and earlier.
use std::string instead of psz for WalletFile

dumpwallet: produce a dump of all keys in a wallet, in a format
compatible with Bitcoin Wallet for Android and Multibit.
importwallet: import such a dump
Compute safe lower bounds on the birth times of all wallet keys. For
pool keys or keys with metadata, the actually stored birth time is
used. For all others, the birth times are inferred from the wallet
transactions.
This function finds all keys affected by a particular output script,
supporting everything ExtractDestinations supports (pay-to-pubkey,
pay-to-pubkeyhash, multisig) and recurses into subscripts (P2SH).
In case no database exists yet, and -txindex(=1) is passed, we currently first
check whether fTxIndex differs from -txindex (and ask the user to reindex in
that case), and only afterwards initialize the database. By swapping these
around (the initialization is a no-op in case the database already exists),
we allow it to be born in txindex mode, without warning.
That also means we don't need to check -reindex anymore, as the wiping/reinit
of the databases happens before checking.
Refactor keytime:
* Key metadata is kept in a CWallet::mapKeyMetadata (std::map<CKeyId,CKeyMetadata>).
* When generating a new key, time is put in that map, and new key is written.
* AddKeyPubKey and AddCryptedKey do not take a creation time argument, but instead
pull it from that map, if it exists there.
Bugfix:
* AddKeyPubKey and AddCryptedKey in CWallet didn't override the CKeyStore
definition anymore. This is fixed, as they no longed need the nCreationTime
argument now.
Also a few related other changes:
* Metadata can be overwritten.
* Only GenerateNewKey calls GetTime(), as it's the only place where we know for
sure a key was not constructed earlier.
* When the nTimeFirstKey is known to be inaccurate, it is set to the value 1
(instead of 0, which would mean unknown).
* Use CPubKey instead of std::vector<unsigned char> where possible.
The new class is accessed via the Params() method and holds
most things that vary between main, test and regtest networks.
The regtest mode has two purposes, one is to run the
bitcoind/bitcoinj comparison tool which compares two separate
implementations of the Bitcoin protocol looking for divergence.
The other is that when run, you get a local node which can mine
a single block instantly, which is highly convenient for testing
apps during development as there's no need to wait 10 minutes for
a block on the testnet.
This adds an introduction screen that is shown when the client is first
started in which the user can choose a data directory.
It is also possible to force the intro screen to appear using command
line argument `-choosedatadir`.
The user is warned that the client will download and store 10Gb of data.
The intro screen shows how much space is available on the device that
contains the chosen directory and warns if this is less than the 10Gb.
To make it possible to translate the introduction dialog, the initialization
sequence is changed so that translations are
loaded before the data directory. This has the by-effect that it is
no longer possible to specify a language in bitcoin.conf inside the data
directory.
This (nearly) doesn't change fee rules at all:
* To make it into the fee transaction area, the dPriority comparison
changed from < to <=
* We now just ignore transactions > MAX_BLOCK_SIZE/4 instead of
doing some calculations to require increasingly large fees as
size increases.
Without this include, sometimes BOOST_VERSION was defined and sometimes
it was not, depending on which includes came before it. The result was a
random mix of sleep or sleep_for for boost versions >= 1.50.
- removes our NewThread() function an replaces remaining calls with
boost::thread with our TraceThread template
- remove ExitThread() function
- fix THREAD_PRIORITY_ABOVE_NORMAL for non Windows OSes
- adds a reindex dialog for Bitcoin-Qt to change -txindex without the need
to supply -reindex
- now also does a -reindex, when removing the -txindex switch
- add new bitcoind.cpp to OTHER_FILES to be able to see it in the Qt
Creator IDE
- remove a Mac-only header from the general HEADERS, as it is already in
macx:HEADERS
Removed AreInputsStandard from CTransaction, made it a regular function in main.
Moved CTransaction::GetOutputFor to CCoinsViewCache.
Moved GetLegacySigOpCount and GetP2SHSigOpCount out of CTransaction into regular functions in main.
Moved GetValueIn and HaveInputs from CTransaction into CCoinsViewCache.
Moved AllowFree, ClientCheckInputs, CheckInputs, UpdateCoins, and CheckTransaction out of CTransaction and into main.
Moved IsStandard and IsFinal out of CTransaction and put them in main as IsStandardTx and IsFinalTx. Moved GetValueOut out of CTransaction into main. Moved CTxIn, CTxOut, and CTransaction into core.
Added minimum fee parameter to CTxOut::IsDust() temporarily until CTransaction is moved to core.h so that CTxOut needn't know about CTransaction.
Added explicit include of main.h in init.cpp, changed include of init.h to include of main.h in net.cpp.
Added function registration for net.cpp in init.cpp's network initialization.
Removed protocol.cpp's dependency on main.h.
TODO: Remove main.h include in net.cpp.
This will allow each to have its own main(), meaning that we can build a common
base client and simply link in the correct startup object to create the
appropriate binary.
- harmonize BitcoinGUI::setClientModel() and RPCConsole::setClientModel()

This commit adds a Linux script that uses tc and iptables to
limit outgoing bandwidth to Bitcoin nodes. All tcp connections with
a source or destination port of 8333 are limited to the chosen rate.
It does not alter the incoming bandwidth. Additionally, outgoing
bandwidth to a host on a local LAN (defined by the LOCALNET variable)
is not limited.
- this directly sets up all GUI elements that have testnet special-casing
without first setting up main net stuff and changing afterwards (titles,
icons etc.)
- also fixes 2 wrong icons shown during testnet usage on our toolbar
- explicitly set the default of all GetBoolArg() calls
- rework getarg_test.cpp and util_tests.cpp to cover this change
- some indentation fixes
- move macdockiconhandler.h include in bitcoin.cpp to the "our headers"
section

This commit decouples the pMiningKey initialization and shutdown from the RPC
threads.
`getwork` and `getblocktemplate` rely on pMiningKey, and can also be ran
from the debug window in the UI even when the RPC server is not running.
Solves issue #2706.
Write bestblock records in wallets:
* Every 20160 blocks synced, no matter what (before: none during IBD)
* Every 144 blocks after IBD (before: for every block, slow)
* When creating a new wallet
* At shutdown
This should result in far fewer spurious rescans.

Remove the pnext pointer in CBlockIndex, and replace it with a
vBlockIndexByHeight vector (no effect on memory usage). pnext can
now be replaced by vBlockIndexByHeight[nHeight+1], but
FindBlockByHeight becomes constant-time.
This also means the entire mapBlockIndex structure and the block
index entries in it become purely blocktree-related data, and
independent from the currently active chain, potentially allowing
them to be protected by separate mutexes in the future.
At startup, check that the expected genesis is loaded. This should prevent
cases where accidentally a datadir from the wrong network is loaded
(testnet vs mainnet, e.g.).
Compiling on my OSX 10.6 build machine, I get:

Linking against the boost_chrono fixes the issue.
Windows builds already link against boost_chrono; Linux doesn't, but compiles (on pull-tester / gitian, at least).
A base_uint used to be made of an array of unsigned ints. This works
fine on most platforms, but might not work on certain present or future
platforms. The code breaks if an unsigned int is 16 or 64 bits, so it's
important to be specific. Also changed "u" to "you".
New method in bitcoinrpc: RunLater, that uses a map of deadline
timers to run a function later.
Behavior of walletpassphrase is changed; before, calling
walletpassphrase again before the lock timeout passed
would result in: Error: Wallet is already unlocked.
You would have to call lockwallet before walletpassphrase.
Now: the last walletpassphrase with correct password
wins, and overrides any previous timeout.
Fixes issue# 1961 which was caused by spawning too many threads.

So we stop getting pull requests (like #2604) fixing problems with disabled Script opcodes.
A hard fork would be required to re-enable these, and if we ever did that we'd require extensive review and testing.
When debugging another issue, I found a hang-during-startup race condition due to
LoadWallet calling SetMinVersion (via LoadCryptedKey).
Writing to the file that you're in the process of reading is a bad idea.
Bitcoin-Qt could core dump if application initialization failed in certain ways.
I double-fixed this:
1) qt/bitcoin.cpp now shuts down core threads cleanly if AppInit2 returns false
2) init.cpp now exits before StartNode() if strErrors is set (no reason to StartNode if we're just going to exit immediately anyway).
Tested by triggering all of the various ways AppInit2 can fail, either by passing bogus command-line arguments or just recompiling tweaked code to simulate failure.
This is a partial fix for #2480
Instead of killing a connection when the receive buffer overflows,
just temporarily halt receiving before that happens. Also, no
matter what, always allow at least one full message in the receive
buffer (otherwise blocks larger than the configured buffer size
would pause indefinitely).
It is possible to have a wallet.dat file without any bestblock
record at all (if created offline, for example), which - when
loaded into a client with a up-to-date chain - does no rescan and
shows no transactions.
Also make sure to write the current best block after a rescan, so
it isn't necessary twice.
* Bugfix: output the correct best block hash (during IBD, it can
differ from the actual current best block)
* Add height to output
* Add hash_serialized, which is a hash of the entire UTXO state.
Can be useful to compare two nodes.
* Add total_amount, the sum of all UTXOs' values.
Previously, JSON-RPC clients accessed URI "/", and the JSON-RPC server
did not care about the URI at all, and would accept any URI as valid.
Change the JSON-RPC server to require URI "/" for all current accesses.
This changes enables the addition of future interfaces at different
URIs, such as pull request #1982 which demonstrates HTTP REST wallet
download.
Or, a future, breaking change in JSON-RPC interface could be introduced
by serving JSON-RPC calls from new URI "/v2/".
This value gets stale really quickly, do not hardcode it into a message.
Completely remove it for now.
Later on, a mechanism will be added to determine fees based on the mempool.

why:
- the current splash-screen has no referring to official images on - https://en.bitcoin.it/wiki/Promotional_graphics
- the current splash screen only exists in a low res jpg
- current splash screen looks dark and "hackish"
- new splash screen should generate positive, "trust-emotions".
- new splash screen gives the user infos about the running client.
- new splash screen can handle long messages (in a lot of - languages the text is cropped in current release)
- new size (x2) 400x312
- contains textual information about the client
- textinfos are dynamicly written to the pixmap
when -testnet is switch on, the splashscreen will show the bitcoin logo in testnet-color (as well as a text [testnet])

Having the export button at the top was confusing people into thinking
the entire wallet was exported.
This commit moves the export button to the address book, receiving
addresses and transaction tabs separately.
Every block index entry currently requires a separately-allocated
CBigNum. By replacing them with uint256, it's just 32 bytes extra
in CBlockIndex itself.
This should save us a few megabytes in RAM, and less allocation
overhead.
- updates ClientModel::getBlockSource() to return all available states and
sorts enum BlockSource in order of usage cases (none default, then reindex,
import and network)
- updates BitcoinGUI::setNumBlocks() to better use getBlockSource() and
also adds a message, when we have NO block source available
- continue the mac behavior of clearing button icons (because it's unusual on mac apps)
- fix: new button variable names, new buttons (verifyMessage, signMessage)

This introduces the concept of the 'sync node', which is the one we
asked for missing blocks. In case the sync node goes away, a new one
will be selected.
For now, the heuristic is very simple, but it can easily be extended
later to add better policies.
- added languages in bitcoin.qrc: bs, ca, cy, eo, gu_IN, hi_IN, ja, la,
lv_LV and th_TH (some translations files were already in src/qt/locale
but not added in the .qrc file
- new windows .ico contains multiple resolutions up to 256px
- new testnet (green) icon
- new png icon for llinux, etc.
- new doxygen icon
- changed the assets-attribution.txt

- this allows us to use the progressbar and the label independently (if
needed) and still prevents setStatusTip() to use them, if one of the 2
is active
- expand the description for updating the translations
- sort the paths/files, which need to have the version number updated, in
alphabetical order
- use a more current version number in git tag and git shortlog
- instead of parsing the project file by using $$_PRO_FILE_ just use
$$TRANSLATIONS, which contains a list of all needed files, to build
our *.qm translation files
It seems there were two mechanisms for assessing whether a CNode
was still in use: a refcount and a release timestamp. The latter
seems to have been there for a long time, as a safety mechanism.
However, this timer also keeps CNode objects alive for far longer
than necessary after disconnects, potentially opening up a DoS
window.
This commit removes the timestamp-based mechanism, and replaces
it with an assert(nRefCount >= 0), to verify that the refcounting
is indeed correctly working.
As these were not updated when 'backporting' the 225430 checkpoint
into head.
Additionally, also report verification progress in debug.log, and
tweak the sigcheck-verification-speed-factor a bit.
- use labelExplanation for sending and receiving tab and move the string
from the ui-file to the source
- ensure that the table holding the label and address is resized so that
the address column fits the address and the label column is stretched to
fit the window size
- rename some stuff for much easier readbility in the code (I find it hard
to get the meaning of stuff like labels or buttons)
Two reasons for this change:
1. Need to always use boost::thread's sleep, even on Windows, so the
sleeps can be interrupted (prior code used Windows' built-in Sleep).
2. I always forgot what units the old Sleep took.
Create a boost::thread_group object at the qt/bitcoind main-loop level
that will hold pointers to all the main-loop threads.
This will replace the vnThreadsRunning[] array.
For testing, ported the BitcoinMiner threads to use its
own boost::thread_group.
- adds 6 methods in BitcoinGUI to access some actions needed by the new
WalletView class
- updates WalletView class to use these instead of trying to duplicate
these
- cleanup walletview.{cpp/h} and remove all unneeded stuff
- this fixes problems with tabs toolbar (#2451) and export broken (#2436)
- more details in #2447

- as QClipboard::Selection isn't available on Windows ensure that the
correct mode is called, but sill allow selection for e.g. X11
- start conversion from QCoreApplication::instance() to qApp in
guiutil.cpp (I intend to harmonize this all over the source with my Qt5
compatibility pull)
This will result in re-requesting invs if we are under heavy inv
load, however as long as we get no more than 16,000 invs in two
minutes, this should have no effect on runtime behavior.
- the send coins context menu entry was not working anymore, because
a non current version of #2220 was merged onto current master
- also removes some unneeded spaces and adds a comment to
WalletModel::getNumTransactions()
Tabs don't fits in line in Spanish/German/Russian when they has two words.
Wallet has limited functionality. It can send & receive coins. So we can
safely rename "Send coins" to "Send" and "Receive coins" to "Receive".
Address book is just stored addresses.
There exists a per-message-processed send buffer overflow protection,
where processing is halted when the send buffer is larger than the
allowed maximum.
This protection does not apply to individual items, however, and
getdata has the potential for causing large amounts of data to be
sent. In case several hundreds of blocks are requested in one getdata,
the send buffer can easily grow 50 megabytes above the send buffer
limit.
This commit breaks up the processing of getdata requests, remembering
them inside a CNode when too many are requested at once.
- this should prevent GUI issues on Mac that were observed before (disappearing
GUI - see #1522)
- the patch ensures, that createTrayIconMenu() is always called on Mac to
process and use our MacDockIconHandler
* Change CNode::vRecvMsg to be a deque instead of a vector (less copying)
* Make sure to acquire cs_vRecvMsg in CNode::CloseSocketDisconnect (as it
may be called without that lock).
1) "optimistic write": Push each message to kernel socket buffer immediately.
2) If there is write data at select time, that implies send() blocked
during optimistic write. Drain write queue, before receiving
any more messages.
This avoids needlessly queueing received data, if the remote peer
is not themselves receiving data.
Result: write buffer (and thus memory usage) is kept small, DoS
potential is slightly lower, and TCP flow control signalling is
properly utilized.
The kernel will queue data into the socket buffer, then signal the
remote peer to stop sending data, until we resume reading again.
Replaces CNode::vRecv buffer with a vector of CNetMessage's. This simplifies
ProcessMessages() and eliminates several redundant data copies.
Overview:
* socket thread now parses incoming message datastream into
header/data components, as encapsulated by CNetMessage
* socket thread adds each CNetMessage to a vector inside CNode
* message thread (ProcessMessages) iterates through CNode's CNetMessage vector
Message parsing is made more strict:
* Socket is disconnected, if message larger than MAX_SIZE
or if CMessageHeader deserialization fails (latter is impossible?).
Previously, code would simply eat garbage data all day long.
* Socket is disconnected, if we fail to find pchMessageStart.
We do not search through garbage, to find pchMessageStart. Each
message must begin precisely after the last message ends.
ProcessMessages() always processes a complete message, and is more efficient:
* buffer is always precisely sized, using CDataStream::resize(),
rather than progressively sized in 64k chunks. More efficient
for large messages like "block".
* whole-buffer memory copy eliminated (vRecv -> vMsg)
* other buffer-shifting memory copies eliminated (vRecv.insert, vRecv.erase)
-dbcache was originally used to set the maximum buffer size in the
BDB environment, and was later changed to set the chainstate cache
and leveldb caches. No need to use it for BDB now that only the
wallet remains there.
This should reduce memory allocation (but not necessarily memory
usage) a bit.
Step for buttons 'up' and 'down' - 0.001. With BTC and mBTC all ok, but
0.001 uBTC is lower than minimal value (satoshi)
User should press 10 times on 'up' button to get 0.01 uBTC

This fixes test_bitcoin failures on openbsd reported by dhill on IRC.
On some systems rand() is a simple LCG over 2^31 and so it produces
an even-odd sequence. ApproximateBestSubset was only using the least
significant bit and so every run of the iterative solver would be the
same for some inputs, resulting in some pretty dumb decisions.
Using something other than the least significant bit would paper over
the issue but who knows what other way a system's rand() might get us
here. Instead we use an internal RNG with a period of something like
2^60 which is well behaved. This also makes it possible to make the
selection deterministic for the tests, if we wanted to implement that.
Switch to using Qt's QLocalServer/QLocalSocket to handle bitcoin
payment links (bitcoin:... URIs)
Reason for switch: the boost::interprocess mechanism seemed flaky,
and doesn't mesh as well with "The Qt Way"
qtipcserver.cpp/h is replaced by paymentserver.cpp/h
Click-to-pay now also works on OSX, with a custom Info.plist
that registers Bitcoin-Qt as a handler for bitcoin: URLs and
an event listener on the main QApplication that handles
QFileOpenEvents (Qt translates 'url clicked' AppleEvents into
QFileOpenEvents automagically).
Two changes:
Use IsConfirmed() instead of IsFinal(), so 'getbalance "*" 0' uses the same
'is this output spendable' criteria as 'getbalance'. Fixes issue #172.
And a tiny refactor to CWallet::GetBalance() (redundant call to IsFinal -- IsConfirmed
calls IsFinal).
getbalance with no arguments and 'getbalance "*" 0' could return different different results,
* Pass txid's to CCoinsView functions by reference instead of by value
* Add a method to swap CCoins, and use it in some places to avoid a
allocating copy + destruct.
* Optimize CCoinsViewCache::FetchCoins to do only a single search
through the backing map.

This is a Linux bash script that will set up tc to limit the outgoing bandwidth for connections to the Bitcoin network. It limits outbound TCP traffic with a source or destination port of 8333, but not if the destination IP is within a LAN (defined as 192.168.x.x).
This means one can have an always-on bitcoind instance running, and another local bitcoind/bitcoin-qt instance which connects to this node and receives blocks from it.
This script attempts to download the signature file `SHA256SUMS.asc` from SourceForge.
It first checks if the signature passes, and then downloads the files specified in the file, and checks if the hashes of these files match those that are specified in the signature file.
The script returns 0 if everything passes the checks. It returns 1 if either the signature check or the hash check doesn't pass. If an error occurs the return value is 2.
[Bitcoin Core](http://bitcoin.org/en/download) is the original Bitcoin client and it builds the backbone of the network. However, it downloads and stores the entire history of Bitcoin transactions (which is currently several GBs); depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more. Thankfully you only have to do this once. If you would like the process to go faster you can [download the blockchain directly](https://bitcointalk.org/index.php?topic=145386.0).
Running
---------------------
The following are some helpful notes on how to run Bitcoin on your native platform.
### Unix
You need the Qt4 run-time libraries to run Bitcoin-Qt. On Debian or Ubuntu:
sudo apt-get install libqtgui4
Unpack the files into a directory and run:
- bin/32/bitcoin-qt (GUI, 32-bit) or bin/32/bitcoind (headless, 32-bit)
- bin/64/bitcoin-qt (GUI, 64-bit) or bin/64/bitcoind (headless, 64-bit)
### Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
### OSX
Drag Bitcoin-Qt to your applications folder, and then run Bitcoin-Qt.
### Need Help?

Note: After you have installed the dependencies, you should check that the Homebrew installed version of OpenSSL is the one available for compilation. You can check this by typing
openssl version
into Terminal. You should see OpenSSL 1.0.1f 6 Jan 2014.
If not, you can ensure that the Homebrew OpenSSL is correctly linked by running
brew link openssl --force
Rerunning "openssl version" should now return the correct version.
### Building `bitcoind`
1. Clone the github tree to get the source code and go into the directory.
git clone https://github.com/bitcoin/bitcoin.git
cd bitcoin
2. Build bitcoind:
./autogen.sh
./configure
make
3. It is a good idea to build and run the unit tests, too:
make check
Creating a release build
------------------------
You can ignore this section if you are building `bitcoind` for your own use.
bitcoind/bitcoin-cli binaries are not included in the Bitcoin-Qt.app bundle.
If you are building `bitcoind` or `Bitcoin-Qt` for others, your build machine should be set up
as follows for maximum compatibility:
All dependencies should be compiled with these flags:
In order to support loading of multiple wallets in bitcoin-qt, a few changes in the UI architecture will be needed.
Fortunately, only four of the files in the existing project are affected by this change.
Two new classes have been implemented in two new .h/.cpp file pairs, with much of the functionality that was previously
implemented in the BitcoinGUI class moved over to these new classes.
The two existing files most affected, by far, are bitcoingui.h and bitcoingui.cpp, as the BitcoinGUI class will require
some major retrofitting.
Only requiring some minor changes is bitcoin.cpp.
Finally, two new headers and source files will have to be added to bitcoin-qt.pro.
Changes to class BitcoinGUI
---------------------------
The principal change to the BitcoinGUI class concerns the QStackedWidget instance called centralWidget.
This widget owns five page views: overviewPage, transactionsPage, addressBookPage, receiveCoinsPage, and sendCoinsPage.
A new class called *WalletView* inheriting from QStackedWidget has been written to handle all renderings and updates of
these page views. In addition to owning these five page views, a WalletView also has a pointer to a WalletModel instance.
This allows the construction of multiple WalletView objects, each rendering a distinct wallet.
A second class called *WalletFrame* inheriting from QFrame has been written as a container for embedding all wallet-related
controls into BitcoinGUI. At present it contains the WalletView instances for the wallets and does little more than passing on messages
from BitcoinGUI to the currently selected WalletView. It is a WalletFrame instance
that takes the place of what used to be centralWidget in BitcoinGUI. The purpose of this class is to allow future
refinements of the wallet controls with minimal need for further modifications to BitcoinGUI, thus greatly simplifying
merges while reducing the risk of breaking top-level stuff.
Changes to bitcoin.cpp
----------------------
bitcoin.cpp is the entry point into bitcoin-qt, and as such, will require some minor modifications to provide hooks for
multiple wallet support. Most importantly will be the way it instantiates WalletModels and passes them to the
singleton BitcoinGUI instance called window. Formerly, BitcoinGUI kept a pointer to a single instance of a WalletModel.
The initial change required is very simple: rather than calling `window.setWalletModel(&walletModel);` we perform the
following two steps:
window.addWallet("~Default", &walletModel);
window.setCurrentWallet("~Default");
The string parameter is just an arbitrary name given to the default wallet. It's been prepended with a tilde to avoid name collisions in the future with additional wallets.
The shutdown call `window.setWalletModel(0)` has also been removed. In its place is now:
To use UPnP for port forwarding behind a NAT router (recommended, as more connections overall allow for a faster and more stable bitcoin experience), pass the following argument to qmake:
::
qmake "USE_UPNP=1"
(in **Qt Creator**, you can find the setting for additional qmake arguments under "Projects" -> "Build Settings" -> "Build Steps", then click "Details" next to **qmake**)
This requires miniupnpc for UPnP port mapping. It can be downloaded from
http://miniupnp.tuxfamily.org/files/. UPnP support is not compiled in by default.
Set USE_UPNP to a different value to control this:
A warning for people using the *static binary* version of Bitcoin on a Linux/UNIX-ish system (tl;dr: **Berkely DB databases are not forward compatible**).
The static binary version of Bitcoin is linked against libdb4.8 (see also `this Debian issue`_).
Now the nasty thing is that databases from 5.X are not compatible with 4.X.
If the globally installed development package of Berkely DB installed on your system is 5.X, any source you
build yourself will be linked against that. The first time you run with a 5.X version the database will be upgraded,
and 4.X cannot open the new format. This means that you cannot go back to the old statically linked version without
* json-rpc errors return a more standard error object. (thanks to Gavin Andresen)
* json-rpc command line returns exit codes.
* json-rpc "backupwallet" command.
* Recovers and continues if an exception is caused by a message you received. Other nodes shouldn't be able to cause an exception, and it hasn't happened before, but if a way is found to cause an exception, this would keep it from being used to stop network nodes.
If you have json-rpc code that checks the contents of the error string, you need to change it to expect error objects of the form {"code":<number>,"message":<string>}, which is the standard. See this thread:
Version 0.3.13 is now available. You should upgrade to prevent potential problems with 0/unconfirmed transactions. Note: 0.3.13 prevents problems if you haven't already spent a 0/unconfirmed transaction, but if that already happened, you need 0.3.13.2.
Changes:
* Don't count or spend payments until they have 1 confirmation.
* Internal version number from 312 to 31300.
* Only accept transactions sent by IP address if -allowreceivebyip is specified.
* Dropped DB_PRIVATE Berkeley DB flag.
* Fix problem sending the last cent with sub-cent fractional change.
* Auto-detect whether to use 128-bit 4-way SSE2 on Linux.
Gavin Andresen:
* Option -rpcallowip= to accept json-rpc connections from another machine.
You can still control the SSE2 use manually with -4way and -4way=0.
Version 0.3.13.2 (SVN rev 161) has improvements for the case where you already had 0/unconfirmed transactions that you might have already spent. Here's a Windows build of it:
* Fixed a wallet.dat compatibility problem if you downgraded from 0.3.17 and then upgraded again
* IsStandard() check to only include known transaction types in blocks
* Jgarzik's optimisation to speed up the initial block download a little
The main addition in this release is the Accounts-Based JSON-RPC commands that Gavin's been working on (more details at http://www.bitcoin.org/smf/index.php?topic=1886.0).
There's more work to do on DoS, but I'm doing a quick build of what I have so far in case it's needed, before venturing into more complex ideas. The build for this is version 0.3.19.
- Added some DoS controls
As Gavin and I have said clearly before, the software is not at all resistant to DoS attack. This is one improvement, but there are still more ways to attack than I can count.
I'm leaving the -limitfreerelay part as a switch for now and it's there if you need it.
- Removed "safe mode" alerts
"safe mode" alerts was a temporary measure after the 0.3.9 overflow bug. We can say all we want that users can just run with "-disablesafemode", but it's better just not to have it for the sake of appearances. It was never intended as a long term feature. Safe mode can still be triggered by seeing a longer (greater total PoW) invalid block chain.
If you have already downloaded version 0.3.20.1, please either add this to your bitcoin.conf file:
maxsendbuffer=10000
maxreceivebuffer=10000
... or download the new version.
