This assertion will occur any time that the client quits without
shutting down properly due to an error condition. As the user will
report this error instead of the error that was the root cause, it is
better to remove it.
Create a monitoring task that counts how many blocks have been found in the last four hours.
If very few or too many have been found, an alert is triggered.
"Very few" and "too many" are set based on a false positive rate of once every fifty years of constant running with constant hashing power, which works out to getting 5 or fewer or 48 or more blocks in four hours (instead of the average of 24).
Only one alert per day is triggered, so if you get disconnected from the network (or are being Sybil'ed) -alertnotify will be triggered after 3.5 hours but you won't get another -alertnotify for 24 hours.
Tested with a new unit test and by running on the main network with -debug=partitioncheck
Run test/test_bitcoin --log_level=message to see the alert messages:
WARNING: check your network connection, 3 blocks received in the last 4 hours (24 expected)
WARNING: abnormally high number of blocks generated, 60 blocks received in the last 4 hours (24 expected)
The -debug=partitioncheck debug.log messages look like:
ThreadPartitionCheck : Found 22 blocks in the last 4 hours
ThreadPartitionCheck : likelihood: 0.0777702

2a6b844 [QT] change transaction amount and height in overview page (Jonas Schnelli)
Instead of only checking height to decide whether to disable script checks,
actually check whether a block is an ancestor of a checkpoint, up to which
headers have been validated. This means that we don't have to prevent
accepting a side branch anymore - it will be safe, just less fast to
do.
We still need to prevent being fed a multitude of low-difficulty headers
filling up our memory. The mechanism for that is unchanged for now: once
a checkpoint is reached with headers, no headers chain branching off before
that point are allowed anymore.
This class groups transactions that have been confirmed in blocks into buckets, based on either their fee or their priority. Then for each bucket, the class calculates what percentage of the transactions were confirmed within various numbers of blocks. It does this by keeping an exponentially decaying moving history for each bucket and confirm block count of the percentage of transactions in that bucket that were confirmed within that number of blocks.
-Eliminate txs which didn't have all inputs available at entry from fee/pri calcs
-Add dynamic breakpoints and tracking of confirmation delays in mempool transactions
-Remove old CMinerPolicyEstimator and CBlockAverage code
-New smartfees.py
-Pass a flag to the estimation code, using IsInitialBlockDownload as a proxy for when we are still catching up and we shouldn't be counting how many blocks it takes for transactions to be included.
-Add a policyestimator unit test
We don't want to erase orphans that still have missing inputs, they should still be tracked as orphans. Also, the transaction thats being accepted can't be an orphan otherwise it would have previously been accepted, so doesn't need to be added to the erase queue.
When the internal miner is enabled at the start of a new node, there
is an near instant assert in TestBlockValidity because its attempting
to mine a block before the top checkpoint.
Also avoids a data race around vNodes.

Add an init message to inform the user what is happening.
libsecp256k1's API changed, so update key.cpp to use it.
Libsecp256k1 now has explicit context objects, which makes it completely thread-safe.
In turn, keep an explicit context object in key.cpp, which is explicitly initialized
destroyed. This is not really pretty now, but it's more efficient than the static
initialized object in key.cpp (which made for example bitcoin-tx slow, as for most of
its calls, libsecp256k1 wasn't actually needed).
This also brings in the new blinding support in libsecp256k1. By passing in a random
seed, temporary variables during the elliptic curve computations are altered, in such
a way that if an attacker does not know the blind, observing the internal operations
leaks less information about the keys used. This was implemented by Greg Maxwell.
bba2216 RPC test for "#5418 Report missing inputs in sendrawtransaction" (Jonas Schnelli)
de8e801 Report missing inputs in sendrawtransaction (Pieter Wuille)
Use a probabilistic bloom filter to keep track of which addresses
we think we have given our peers, instead of a list.
This uses much less memory, at the cost of sometimes failing to
relay an address to a peer-- worst case if the bloom filter happens
to be as full as it gets, 1-in-1,000.
Measured memory usage of a full mruset setAddrKnown: 650Kbytes
Constant memory usage of CRollingBloomFilter addrKnown: 37Kbytes.
This will also help heap fragmentation, because the 37K of storage
is allocated when a CNode is created (when a connection to a peer
is established) and then there is no per-item-remembered memory
allocation.
I plan on testing by restarting a full node with an empty peers.dat,
running a while with -debug=addrman and -debug=net, and making sure
that the 'addr' message traffic out is reasonable.
(suggestions for better tests welcome)
For when you need to keep track of the last N items
you've seen, and can tolerate some false-positives.

This commit adds several tests to the script_invalid.json data which
exercise some edge conditions that are not currently being tested.
These are mainly being added to cover several cases a branch coverage
analysis of btcd showed are not already being covered, but given more
tests of edge conditions are always a good thing, I'm contributing
them upstream.
The test which is intended to prove that the script engine is properly
rejecting non-minimally encoded PUSHDATA4 data is using the wrong
opcode and value. The test is using 0x4f, which is OP_1NEGATE instead
of the desired 0x4e, which is OP_PUSHDATA4. Further, the push of data
is intended to be 256 bytes, but the value the test is using is
0x00100000 (4096), instead of the desired 0x00010000 (256).
This commit fixes both issues.
This was found while examining the branch coverage in btcd against only
these tests to help find missing branch coverage.
This adds a -prune=N option to bitcoind, which if set to N>0 will enable block
file pruning. When pruning is enabled, block and undo files will be deleted to
try to keep total space used by those files to below the prune target (N, in
MB) specified by the user, subject to some constraints:
- The last 288 blocks on the main chain are always kept (MIN_BLOCKS_TO_KEEP),
- N must be at least 550MB (chosen as a value for the target that could
reasonably be met, with some assumptions about block sizes, orphan rates,
etc; see comment in main.h),
- No blocks are pruned until chainActive is at least 100,000 blocks long (on
mainnet; defined separately for mainnet, testnet, and regtest in chainparams
as nPruneAfterHeight).
This unsets NODE_NETWORK if pruning is enabled.
Also included is an RPC test for pruning (pruning.py).
Thanks to @rdponticelli for earlier work on this feature; this is based in
part off that work.
has parts of @mhearn #4351
* allows querying the utxos over REST
* same binary input and outputs as mentioned in Bip64
* input format = output format
* various rpc/rest regtests
Ever since #5957 there has been the problem that older RPC test cases
(as can be found plenty in open pulls) use setgenerate() on regtest,
assuming a different interpretation of the arguments. Directly
generating a number of blocks has been split off into a new method
`generate` - however using `setgenerate` with the previous arguments will
result in spawning an unreasonable number of threads, and well, simply
not work as expected without clear indication of the error.
Add an error to point the user at the right method.

On hosts that had spent some time with a failed internet connection their
nAttempts penalty was going through the roof (e.g. thousands for all peers)
and as a result the connect search was pegging the CPU and failing to get
more than a 4 connections after days of running (because it was taking so
long per try).
According to Tor's extensions to the SOCKS protocol
(https://gitweb.torproject.org/torspec.git/tree/socks-extensions.txt)
it is possible to perform stream isolation by providing authentication
to the proxy. Each set of credentials will create a new circuit,
which makes it harder to correlate connections.
This patch adds an option, `-proxyrandomize` (on by default) that randomizes
credentials for every outgoing connection, thus creating a new circuit.

Compare the block download timeout to what the timeout would be if calculated

present conditions is shorter, then set that to be the time after which we

SendMessages will now call getheaders on both inbound and outbound peers,
once the headers chain is close to synced. It will also try downloading
blocks from inbound peers once we're out of initial block download (so
inbound peers will participate in parallel block fetching for the last day
or two of blocks being downloaded).
This adds more tests to CheckBlockIndex:

- BLOCK_VALID_TRANSACTIONS is true iff nTx > 0
- BLOCK_VALID_TRANSACTIONS is true for a block and all parents iff
nChainTx > 0

This is an advanced feature which will disable any kind of automatic
transaction broadcasting in the wallet. This gives the user full control
of how the transaction is sent.
For example they can broadcast new transactions through some other
mechanism themselves, after getting the transaction hex through `gettransaction`.
This just adds the option `-walletbroadcast=<0,1>`. Right now these
transactions will get the status
Status: conflicted, has not been successfully broadcast yet
They shouldn't be shown as conflicted at all (`walletconflicts` is empty). This status
will go away when the transaction is received through the network.

This adds a -checkblockindex (defaulting to true for regtest), which occasionally
does a full consistency check for mapBlockIndex, setBlockIndexCandidates, chainActive, and
mapBlocksUnlinked.
The scope of `std::locale::global` appears to be smaller than `setenv("LC_ALL", ...)` and insufficient to fix messed up locale settings for the whole application.
This fixes a subtle bug involving block re-orgs and non-standard transactions.
Start with a block containing a non-standard transaction, and
one or more transactions spending it in the memory pool.
Then re-org away from that block to another chain that does
not contain the non-standard transaction.
Result before this fix: the dependent transactions get stuck
in the mempool without their parent, putting the mempool
in an inconsistent state.
Tested with a new unit test.

Adds a regression test for the wallet's ResendWalletTransactions function, which uses a new, hidden RPC command "resendwallettransactions."
I refactored main's Broadcast signal so it is passed the best-block time, which let me remove a global variable shared between main.cpp and the wallet (nTimeBestReceived).
I also manually tested the "rebroadcast unconfirmed every half hour or so" functionality by:
1. Running bitcoind -connect=0.0.0.0:8333
2. Creating a couple of send-to-self transactions
3. Connect to a peer using -addnode
4. Waited a while, monitoring debug.log, until I see:
```2015-03-23 18:48:10 ResendWalletTransactions: rebroadcast 2 unconfirmed transactions```
One last change: don't bother putting ResendWalletTransactions messages in debug.log unless unconfirmed transactions were actually rebroadcast.

It is also more efficient.
During startup, when adding pending wallet transactions, which spend outputs of
other pending wallet transactions, back to the memory pool, and when they are
added out of order, it appears as if they are orphans with missing inputs.
Those transactions are then rejected and flagged as "conflicting" (= not in the
memory pool, not in the block chain).
To prevent this, transactions are explicitly sorted.

When re-indexing, there are a few cases where garbage data may be skipped in
the block files. In these cases, the indices are correctly written to the index
db, however the pointer to the next position for writing in the current block
file is calculated by adding the sizes of the valid blocks found.
As a result, when the re-index is finished, the index db is correct for all
existing blocks, but the next block will be written to an incorrect offset,
likely overwriting existing blocks.
Rather than using the sum of all valid blocks to determine the next write
position, use the end of the last block written to the file. Don't assume that
the current block is the last one in the file, since they may be read
out-of-order.
UNITTEST parameter are not used by any current tests, and the model
(modifyable parameters) is inconvenient when unit-testing. As
they are stored in a global structure eevery test
would have to (re)set up its own parameters.
For consistency it is also better to test with MAIN parameters.

We've chosen to htons/ntohs explicitly on reading and writing
(I do not know why). But as READWRITE already does an endian swap
on big endian, this means the port number gets switched around,
which was what we were trying to avoid in the first place. So
to make this compatible, serialize it as FLATDATA.
- Detect endian instead of stopping configure on big-endian
- Add `byteswap.h` and `endian.h` header for compatibility with
Windows and other operating systems that don't come with them
- Update `crypto/common.h` functions to use compat
endian header
This was added a while ago for testing purposes, but was never intended to be

These dialogs will be something that people occasionally open, not keep
open during their session, so just popping it up in a sensible place
is good enough. Remembering only creates potential issues, like spawning
it outside the current screen area.
On Ubuntu this causes the dialogs to be positioned in the
middle of the main dialog, so I didn't add code for that. YMMV.

Split GetNextWorkRequired() into two functions to allow the difficulty calculations to
be tested without requiring a full blockchain.
Add unit tests to cover basic difficulty calculation, plus each of the min/max actual
time, and maximum difficulty target conditions.
This makes it easier for us to replace it if desired, since it's now only in
one spot. Also, it avoids the openssl include from allocators.h, which
essentially forced openssl to be included from every compilation unit.
The fix to NegateSignatureS caused a test which had been failing
in IsValidSignatureEncoding to then fail in IsLowDERSignature.

Normally bitcoin core does not display any network originated strings without

The only time when a client sends a "getaddr" message is when he
esatblishes an Outbound connection (see ProcessMessage() in
src/main.cpp). Another bitcoin client is expected to receive a
"getaddr" message only on Inbound connection. Ignoring "gettaddr"
requests on Outbound connections can resolve potential privacy issues
(and as was said such request normally do not happen anyway).

of that we need to verify that single and accumulated amounts are
in a valid range and no variable overflow has happened.
- fixes#5624 (#5622)
Thanks @SergioDemianLerner for reporting that issue and also supplying us
with a possible solution.
- add static verifyAmount() function to PaymentServer and move the logging
on error into the function
- also add a unit test to paymentservertests.cpp
c++11 (libc++'s stdlib implementation anyway) doesn't allow for map types to be
forward-declared. for example:
class foo;
std::map<int, foo> bar; // error, foo has not been defined.
class foo{};
Since CWallet and CWalletTx are inter-dependent, but only std::map<*,CWalletTx>
is used, forward-declare CWallet instead and define CWalletTx first.
Despite the mangled git diff, this change only amounts to moving ~320 lines in
a single chunk.
Instead, create a separate function that applies the undo operation of a
CTxInUndo object onto a CCoinsViewCache. This method is used from
DisconnectBlock.
This fixes a potential race condition in the CCheckQueueControl constructor,
which was looking directly at data in CCheckQueue without acquiring its lock.
Remove the now-unnecessary friendship for CCheckQueueControl
Note that this will also require translation changes in Transifex for the key
"A fee higher than %1 is considered an insanely high fee." which is now

- update for RPC methods added since 84d13ee: setmocktime,
invalidateblock, reconsiderblock. Only the first, setmocktime, required a change,
the other two are thread safe.
The main thread spends time waiting for the DetectShutdownThread.
So why not just run this waiting loop function in the main thread?
One thread-stack less saves 4MB of virtual memory on 32-bit, and 8MB on
64-bit.
The default font changed again.
The real fix is to compile qt against a >= 10.8 sdk, but this is simple enough
to backport to 0.10 to avoid having to do that there.
Note: NSAppKitVersionNumber is a double and there's no official value for
NSAppKitVersionNumber10_10. Since == isn't reliable for doubles, use Apple's
guidelines for testing versions here:
https://developer.apple.com/library/mac/releasenotes/AppKit/RN-AppKit/
Chinese and Japanese fonts have been hard-coded as well, otherwise they fail to
show up at all.
This avoids a regression for issues like #334 where high speed
repeated connections eventually run the HTTP client out of
sockets because all of theirs end up in time_wait.
Maybe the trade-off here is suboptimal, but if both choices will
fail then we prefer fewer changes until the root cause is solved.
- now logs if -rootcertificates="" was used to disable payment request
authentication via X.509 certificates
- also logs which file is used as trusted root cert, if -rootcertificates
is set

16a5c18 Add a -rpckeepalive and disable RPC use of HTTP persistent connections. (Gregory Maxwell)
- this is based on #4122 (which can be closed)
Currently a payment request is only checked for expiration upon receipt.
It should be checked again immediately before sending coins to prevent
the user from paying to an expired invoice which would then require a
customer service interaction.
- add static verifyExpired() function to PaymentServer to be able to use
the same validation code in GUI and unit-testing code
- extend unit tests to use that function and also add an unit test which
overflows, because payment requests allow expires as uint64, whereas we
use int64_t for verification of expired payment requests
It turns out that some miners have been staying with old versions of
Bitcoin Core because their software behaves poorly with persistent
connections and the Bitcoin Core thread and connection limits.
What happens is that underlying HTTP libraries leave connections open
invisibly to their users and then the user runs into the default four
thread limit. This looks like Bitcoin Core is unresponsive to RPC.
There are many things that should be improved in Bitcoin Core's behavior
here, e.g. supporting more concurrent connections, not tying up threads
for idle connections, disconnecting kept-alive connections when limits
are reached, etc. All are fairly big, risky changes.
Disabling keep-alive is a simple workaround. It's often not easy to turn
off the keep-alive support in the client where it may be buried in some
platform library.
If you are one of the few who really needs persistent connections you
probably know that you want them and can find a switch; while if you
don't and the misbehavior is hitting you it is hard to discover the
source of your problems is keepalive related. Given that it is best
to default to off until they're handled better.
- verify that payment request network matches client network
- add static verifyNetwork() function to PaymentServer to be able to use
the same validation code in GUI and unit-testing code
- add a second PaymentRequest Test CA certificate to paymentrequestdata.h
(serial number f0:da:97:e4:38:d7:64:16) as caCert2_BASE64
- rename existing Test CA certificate to caCert1_BASE64
- rename existing payment request data to know they belong to
caCert1_BASE64
- update comments to reflect the changes and add a missing comment to one
of the payment requests
b468e81 Qt: Clarify sign/verify dialog text to specifically state that these messages only prove one receives with the address in question, and makes no claim to sender of transactions (Luke Dashjr)
This harmonizes the block fetch timeout with the existing ping timeout
and eliminates a guaranteed eventual failure from congestion collapse
for a network operating right at its limit.
It's unlikely that we wouldn't suffer other failures if we were really
anywhere near the network's limit, and a complete avoidance of congestion
collapse risk requires (I think) an exponential back-off. So this isn't
a major concern, but I think it's also useful for reducing the complexity
of understanding out timeouts.
- it is helpful to be able to test and verify payment request processing
by allowing self signed root certificates (e.g. generated by Gavins
"certificate authority in a box")
- This option is just shown in the UI options, if -help-debug is enabled.
- before it was possible to use the steps to change e.g. amouns of
authenticated or unauthenticated payment requests (AmountSpinBox is
already set to read-only here) - this is now fixed
- also move the reimplemented stepEnabled() function to the
protected section of our class, where it belongs (see Qt doc)
New versions of OpenSSL will reject non-canonical DER signatures. However,
it'll happily decode them. Decode then re-encode before verification in order
to ensure that it is properly consumed.
Makes it possible to compactly provide a delibrately invalid signature
for use with CHECK(MULTI)SIG. For instance with BIP19 if m != n invalid
signatures need to be provided in the scriptSig; prior to this change
those invalid signatures would need to be large DER-encoded signatures.
Note that we may want to further expand on this change in the future by
saying that only OP_0 is a "valid" invalid signature; BIP19 even with
this change is inherently malleable as the invalid signatures can be any
validly encoded DER signature.

This will disconnect peers that do not transfer a block in 10 minutes, plus
5 minutes for every previously queued block with validated headers
(accomodating downstream bandwidth down to a few kilobytes per second - below
that the node would have trouble staying synchronized anyway).
on rare occasions, rand() was returning duped values, causing duplicate
transactions.
BuildMerkleTree happily used these, but CPartialMerkleTree caught them and
returned a null merkle root.
Rather than taking changes with rand(), use the loop counter to guarantee
unique values.
At sipa's request, also remove the remaining uses of rand().

Instead of using a fixed-width font in a label, which virtually
guarentees a horizontal scrollbar, use a proper text-document
that can re-layout based on user input.
Remove initialization from vector (as this is only used in the tests).
Also implement SetHex and GetHex in terms of uint256, to avoid
duplicate code as well as avoid endianness issues (as they
work in term of bytes).
- Methods that access the guts of arith_uint256 are removed,
as these are incompatible between endians. Use uint256 instead
- Serialization is no longer needed as arith_uint256's are never
read or written
- GetHash is never used on arith_uint256
If uint256() constructor takes a string, uint256(0) will become
dangerous when uint256 does not take integers anymore (it will go
through std::string(const char*) making a NULL string, and the explicit
keyword is no help).
SignatureHash and its test function SignatureHashOld
return uint256(1) as a special error signaling value.
Return a local static constant with the same value instead.
Previous behavior with IsFinalTx() being an IsStandard() rule was rather
confusing and interferred with testing of protocols that depended on
nLockTime.
Otherwise, if CCoinsViewCache::ModifyCoins throws an exception in between
setting hasModifier and constructing the CCoinsModifier, the cache ends up
in an inconsistent state, resulting in an assert failure in the next
modification.

It is easily confused with CCoinsViewCache(CCoinsView*), which creates a sub-cache, but instead of creating a sub-cache, the copy constructor would copy the original and use that original's base, defeating the intended isolation.
