Allows the user to pass null as the second or third parameter
to signrawtransaction, in case you need to (for example) fetch
private keys from the wallet but want to specify the hash type.
This does two things:
1) Now does not output to debug.log if -printtodebugger flag is passed
2) Unit tests set -printtodebugger so only test results are output to stdout
Note that -printtodebugger only actually prints to the debugger on Windows.
If 950 of the last 1,000 blocks are nVersion=2, reject nVersion=1
(or zero, but no bitcoin release has created block.nVersion=0) blocks
-- 75 of last 100 on testnet3.
This rule is being put in place now so that we don't have to go
through another "express support" process to get what we really
want, which is for every single new block to include the block height
in the coinbase.
"Version 2" blocks are blocks that have nVersion=2 and
have the block height as the first item in their coinbase.
Block-height-in-the-coinbase is strictly enforced when
version=2 blocks are a supermajority in the block chain
(750 of the last 1,000 blocks on main net, 51 of 100 for
testnet). This does not affect old clients/miners at all,
which will continue producing nVersion=1 blocks, and
which will continue to be valid.
- extend bitcoin-qt.rc to include meta information, which is displayed on
Windows, when looking in the executable properties and selecting

This is the last time for 0.7.0. We should avoid message changes
until the release. Translators can use the remaining time to update their languages on
Transifex.
The other languages need to be merged from Transifex just before release.
Signrawtransaction rpc was crashing when some inputs were unknown,
and even with that fixed was failing to handle all the known inputs
if there were unknown inputs in front of them. This commit instead
attempts to fetch inputs one at a time.
- this enables DEP on all Windows version which support the
SetProcessDEPPolicy() call in Kernel32.dll
- use a dynamic approach via GetProcAddress() to not rely on headers or
compiler libs
- this is the same way the Tor-project does it
- add enableApplyButton() and disableApplyButton() to optionsdialog.{h/cpp}
- they are used to ensure the Ok button does not get disabled, when Apply needs to be disabled (standard UX should allow Ok always to dismiss the dialog and only disable it, when we have a faulty proxy IP)
- disable Apply after initially loading the settings, as nothing new needs to be saved
- remove orphan settings from optionsdialog.ui that are default anyway
- If the height is in the first half, start at the genesis block and go up, rather than at the top
- Cache the last lookup and use it as a reference point if it's close to the next request, to make linear lookups always fast
- ensure warnings always start with "Warning:" and that the first
character after ":" is written uppercase
- ensure the first sentence in warnings ends with an "!"
- remove unneeded spaces from Warning-strings
- add missing Warning-string translation
- remove a "\n" and replace with untranslatable "<br><br>"
- place "-?" option at first
- re-work description and "\n" usage for Gavins new block creation options
to better match current description syntax
- ensure no "\n" is in translated strings, which is better for Transifex
The new bytes are based on "11" to appeal to Gavin's 11 fetish.
This breaks existing testnet3 nodes as the blockchain files
are also versioned. To upgrade a node delete everything
except wallet.dat from your .bitcoin/testnet3 folder.
Modify CreateNewBlock so that instead of processing all transactions
in priority order, process the first 27K of transactions in
priority order and then process the rest in fee-per-kilobyte
order.
This is the first, minimal step towards better a better fee-handling
system for both miners and end-users; this patch should be easy
to backport to the old versions of Bitcoin, and accomplishes the
most important goal-- allow users to "buy their way in" to blocks
using transaction fees.
- remove duplicate includes, that are already present in ui_optionsdialog.h
- change QIntValidator to not allow 0 as port-number
- re-order some function calls to match the Ui element order, for better readbility and to prepare for the addition of further IPv6 and Tor proxy options
- restat warning for the language selection is only shown, when the language was changed (not on simply activating the Ui element)
- split check for object == ui->proxyIp into seperate if-clause
- micro-optimize the code in the above mentioned if-clause
- unify used format for comments in the code
- introduce handleProxyIpValid() function, which handles UI elements and the
save button states for valid/invalid proxy IPs
- add IMPLEMENT_RANDOMIZE_STACK for ipcThread()
- log / print boost interprocess exceptions
- use MAX_URI_LENGTH in guiconstants.h (also used in qrcodedialog.cpp)
- remove unneeded includes and ipcShutdown() from qtipcserver.cpp
- fix a small mem-leak by deleting mq before re-using it
- make ipcThread() and ipcThread2() static functions
- add some more comments

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

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

to them via a SOCKS5 proxy.
Prior to this change, each TX typically generated 3+ debug messages,
askfor tx 8644cc97480ba1537214 0

and two messages for each orphan tx received

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

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

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

The best log rotation method formerly available was to configure
logrotate with the copytruncate option. As described in the logrotate
documentation, "there is a very small time slice between copying the
file and truncating it, so some logging data might be lost".
By sending SIGHUP to the server process, one can now reopen the debug
log file without losing any data.
Acquire an exclusive, advisory lock before sending output to debug.log
and release it when we're done. This should avoid output from multiple
threads being interspersed in the log file.
We can't use CRITICAL_SECTION machinery for this because the debug log
is written during startup and shutdown when that machinery is not
available.
(Thanks to Gavin for pointing out the CRITICAL_SECTION problems based
on his earlier work in this area)
Create a maximum-10MB signature verification result cache.
This should almost double the number of transactions that
can be processed on a given CPU, because before this change
ECDSA signatures were verified when transactions were added
to the memory pool and then again when they appeared in
a block.
Loop over all inputs doing inexpensive validity checks first,
and then loop over them a second time doing expensive signature
checks. This helps prevent possible CPU exhaustion attacks
where an attacker tries to make a victim waste time checking
signatures for invalid transactions.
Remove orphan transactions from memory once
all of their parent transactions are received
and they're still not valid.
Thanks to Sergio Demian Lerner for suggesting this fix.

Also, trim a few trailing whitespace in main.cpp.
Immediately issue a "getblocks", instead of a "getdata" (which will

As noticed by sipa (Pieter Wuille), this can happen when CBigNum::setint64() is
called with an integer value of INT64_MIN (-2^63).
When compiled with -ftrapv, the program would crash. Otherwise, it would
execute an undefined operation (although in practice, usually the correct one).
One of the test cases currently aborts when using gcc's flag -ftrapv, due to
negating an INT64_MIN int64 variable, which is an undefined operation.
This will be fixed in a subsequent commit.
CBigNum::setint64() does 'n <<= 8', where n is of type "long long".
This leads to shifting onto and past the sign bit, which is undefined
behavior in C++11 and can cause problems in the future.
This prevents an undefined operation in main.cpp, when shifting the hash value
left by 32 bits.
Shifting a signed int left into the sign bit is undefined in C++11.

Introduce a boolean variable for each "network" (ipv4, ipv6, tor, i2p),
and track whether we are likely to able to connect to it. Addresses in
"addr" messages outside of our network get limited relaying and are not
stored in addrman.
There are plans to let Bitcoin function as Tor/I2P hidden service.
To do so, we could use the established encoding provided by OnionCat
and GarliCat (without actually using those tools) to embed Tor/I2P
addresses in IPv6.
This patch makes these addresses considered routable, so they can
travel over the Bitcoin network in 'addr' messages. This will hopefully
make it easier to deploy real hidden service support later.
This will make bitcoin relay valid routable IPv6 addresses, and when
USE_IPV6 is enabled, listen on IPv6 interfaces and attempt connections
to IPv6 addresses.
FetchInputs already logs failures internally. This commit makes the logging

After this commit, only one line is logged:

Pull request #948 introduced a fix for nodes stuck on a long side branch

-externalip=<ip> can be used to explicitly set the public IP address
of your node. -discover=0 can be used to disable the automatic public

Add an option -detachdb (and entry in OptionDialog), without which no
lsn_reset is called on addr.dat and blkindex.dat. That means these
files cannot be moved to a new environment, but shutdown can be
significantly faster. The wallet file is always lsn_reset'ed.
-detachdb corresponds to the old behaviour, though it is off by
default now to speed up shutdowns.
Rather than storing ftell(3)'s return value -- a long -- in an

non-negative value, we store in nBlockPosRet.
C++ STL ::size() generally returns unsigned, which implies that "int idx"

correctly defined as unsigned.

In ISO C++, the signedness of 'char' is undefined. On some platforms (e.g.
ARM), 'char' is an unsigned type, but some of the code relies on 'char' being
signed (as it is on x86). This is indicated by compiler warnings like this:
bignum.h: In constructor 'CBigNum::CBigNum(char)':
bignum.h:81:59: warning: comparison is always true due to limited range of data type [-Wtype-limits]
util.cpp: In function 'bool IsHex(const string&)':
util.cpp:427:28: warning: comparison is always false due to limited range of data type [-Wtype-limits]
In particular, IsHex erroneously returned true regardless of the input
characters, as long as the length of the string was a positive multiple of 2.
Note: For testing, it's possible using GCC to force char to be unsigned by
adding the -funsigned-char parameter to xCXXFLAGS.
This commit removes the dependency of serialize.h on PROTOCOL_VERSION,
and makes this parameter required instead of implicit. This is much saner,
as it makes the places where changing a version number can have an
influence obvious.
Conflict:
* cs_main in ProcessMessages() (before calling ProcessMessages)
* cs_vSend in CNode::BeginMessage
versus:
* cs_vSend in ThreadMessageHandler2 (before calling SendMessages)
* cs_main in SendMessages
Even though cs_vSend is a try_lock, if it succeeds simultaneously with
the locking of cs_main in ProcessMessages(), it could cause a deadlock.
Since auto-remove-db-logs was enabled, each time a CTxDB was closed
outside of the initial download window, it causes a checkpoint + log
cleanup. This is overkill, so reduce the sync frequency to once per
minute at most.
This is more clear to users than when the program simply disappears (usually during initialization). It still logs the message to the console and debug log as well.
- Move scripts/qt to share/qt, to clean up toplevel directories
- Update english ts file which is used to source messages for Transifex
- In extract_strings_qt.py use a glob *.h *.cpp, this is safe now that the Wx UI files are removed
Open database once per "tx" message, rather than multiple times,
in the case of orphan transaction presence.
As a side effect, a now-unused CTransaction::AcceptToMemoryPool()
variant is removed.
Reference miner exists for testnet-in-a-box type situations, and as a
reference. We don't care enough about highly optimized internal
mining to keep workarounds like this.
* move PROTOCOL_VERSION to version.h
* move CLIENT_VERSION* to version.h, make available past cpp stage
* clearly separate client, network version portions of version.h
Add a pong message that is sent in reply to a ping. It echoes back a nonce
field that is now added to the ping message. Send a nonce of zero in ping
messages.

Modified Mike's change to introduce a mild form of protocol documentation in
version.h.
Where possible, use boost::filesystem::path instead of std::string or
char* for filenames. This avoids a lot of manual string tinkering, in
favor of path::operator/.
GetDataDir is also reworked significantly, it now only keeps two cached
directory names (the network-specific data dir, and the root data dir),
which are decided through a parameter instead of pre-initialized global
variables.
Finally, remove the "upgrade from 0.1.5" case where a debug.log in the
current directory has to be removed.
For Qt builds, the build.h file is moved to build/build.h. For regular
builds, it is moved to obj/build.h. This allows the Qt build to be done
in a different directory than the source, and without interfering with
other builds.
All client version information is moved to version.cpp, which optionally
(-DHAVE_BUILD_INFO) includes build.h. build.h is automatically generated
on supporting platforms via contrib/genbuild.sh, using git describe.
The git export-subst attribute is used to put the commit id statically
in version.cpp inside generated archives, and this value is used if no
build.h is present.
The gitian descriptors are modified to use git archive instead of a
copy, to create the src/ directory in the output. This way,
src/src/version.cpp will contain the static commit id. To prevent
gitian builds from getting the "-dirty" marker in their git-describe
generated identifiers, no touching of files or running sed on the
makefile is performed anymore. This does not seem to influence
determinism.
- converted openBictoinAction to toggleHideAction
- put GUIUtil functions into a namespace instead of a class
- put window-related functions together in optionsdialog
Reasoning:
- toggle is more typical behaviour
- it's more functional
- better UX
The typical issue with toggling visibility is that when a window
is obscured by other windows but in the 'shown' state, hiding it
isn't what you want. I've added an 'isObscured' function to GUIUtil
that checks several pixels in the window to see if they are visible
on the desktop so that an obscured but shown window can be raised.

Keep a global counter for nOutbound, protected with its own waitable
critical section, and wait when all outbound slots are filled, rather
than polling.
This removes the (on average) 1 second delay between a lost connection
and a new connection attempt, and may speed up shutdowns.
This commit simplifies the locking system: CCriticalSection becomes a
simple typedef for boost::interprocess::interprocess_recursive_mutex,
and CCriticalBlock and CTryCriticalBlock are replaced by a templated
CMutexLock, which wraps boost::interprocess::scoped_lock.
By making the lock type a template parameter, some critical sections
can now be changed to non-recursive locks, which support waiting via
condition variables. These are implemented in CWaitableCriticalSection
and WAITABLE_CRITICAL_BLOCK.
CWaitableCriticalSection is a wrapper for a different Boost mutex,
which supports waiting/notification via condition variables. This
should enable us to remove much of the used polling code. Important
is that this mutex is not recursive, so functions that perform the
locking must not call eachother.
Because boost::interprocess::scoped_lock does not support assigning
and copying, I had to revert to the older CRITICAL_BLOCK macros that
use a nested for loop instead of a simple if.
- rename wxMessageBox, remove redundant arguments to noui/qtui calls
- also, add flag to force blocking, modal dialog box for disk space warning etc
- clarify function naming
- no more special MessageBox needed from AppInit2, as window object is created before calling AppInit2
- Overall, this is better design
- This fixes problems with the address book UI not updating when the address book is changed through RPC
- Move Statusbar change detection responsibility to ClientModel
It was too hyperactive.
gmaxwell: I mean that right now when the block gap goes over an hour it starts showing synchronizing. Increasing that to 90 minutes or so would make it only happen about 6.4 times per year
