If number of conflict confirms cannot be determined, this means
that the block is still unknown or not yet part of the main chain,
for example during a reindex. Do nothing in that case,
instead of crash with an assertion.
Fixes#7234.
This test is no longer relevant.
It was introduced in 8c222dca4f to check
the switch to 1MB blocks after the BDB too-many-locks issue back in
2013. The switching code has been long since removed.
It also needs a specific data file that is hard to find. I've verified
in #6320 that it still passes, however I think there is zero reason to
keep it.
Closes#6320.

ProcessNewBlock would return failure early if CheckBlock failed, before
calling AcceptBlock. AcceptBlock also calls CheckBlock, and upon failure
would update mapBlockIndex to indicate that a block was failed. By returning
early in ProcessNewBlock, we were not marking blocks that fail a check in
CheckBlock as permanently failed, and thus would continue to re-request and
reprocess them.
This corrects a bug the case of tying group size where the code may
fail to select the group with the newest member. Since newest time
is the final selection criteria, failing to break ties on it
on the step before can undermine the final selection.
Tied netgroups are very common.

With automatic tor HS support in place we should probably not be providing
absolute protection for local peers, since HS inbound could be used to
attack pretty easily. Instead, this counts on the latency metric inside
AttemptToEvictConnection to privilege actually local peers.
(cherry picked from commit 46dbcd4833115401fecbb052365b4c7725874414)
Previously didn't make clear that the ContextualCheckBlock* functions
meant the block headers as context - not the UTXO set itself - and that
ConnectBlock() also did UTXO-related validity checks (in the future we
may split that functionality into a separate UTXO-specific contextual
check block function).
Also, reordered to put validity checks first for better readability.
Also renames whitelistalwaysrelay.
Nodes relay all transactions from whitelisted peers, this
gets in the way of some useful reasons for whitelisting
peers-- for example, bypassing bandwidth limitations.
The purpose of this forced relaying is for specialized gateway
applications where a node is being used as a P2P connection
filter and multiplexer, but where you don't want it getting
in the way of (re-)broadcast.
This change makes it configurable with whitelistforcerelay.

9e69717 Make wallet descendant searching more efficient (Alex Morcos)
Unconfirmed transactions that are not in your mempool either due to eviction or other means may be unlikely to be mined. abandontransaction gives the wallet a way to no longer consider as spent the coins that are inputs to such a transaction. All dependent transactions in the wallet will also be marked as abandoned.
Due to include ordering, defining in one place was not enough to ensure correct
usage. Use global defines so that we don't have to worry abou this ordering.
Also add a comment in configure about the test.

noexcept is default for destructors as of c++11. By throwing in reverselock's
destructor if it's lock has been tampered with, the likely result is
std::terminate being called. Indeed that happened before this change.
Once reverselock has taken another lock (its ctor didn't throw), it makes no
sense to try to grab or lock the parent lock. That is be broken/undefined
behavior depending on the parent lock's implementation, but it shouldn't cause
the reverselock to fail to re-lock when destroyed.
To avoid those problems, simply swap the parent lock's contents with a dummy
for the duration of the lock. That will ensure that any undefined behavior is
caught at the call-site rather than the reverse lock's destruction.
Barring a failed mutex unlock which would be indicative of a larger problem,
the destructor should now never throw.
This is ugly, but temporary. boost::filesystem will likely be dropped soon
after c++11 is enabled. Otherwise, we could simply roll our own copy_file. I've
fixed this at the buildsystem level for now in order to avoid mixing in
functional changes.
Explanation:
If boost (prior to 1.57) was built without c++11, it emulated scoped enums
using c++98 constructs. Unfortunately, this implementation detail leaked into
the abi. This was fixed in 1.57.
When building against that installed version using c++11, the headers pick up
on the native c++11 scoped enum support and enable it, however it will fail to
link. This can be worked around by disabling c++11 scoped enums if linking will
fail.
Add an autoconf test to determine incompatibility. At build-time, if native
enums are being used (a c++11 build), and force-disabling them causes a
successful link, we can be sure that there's an incompatibility and enable the
work-around.
Don't scan the wallet to see if the current key has been used if we're going to make a new key anyway.
Stop scanning the wallet as soon as we see that the current key has been used.
Don't call isValid() twice on the current key.
After discussion in #7164 I think this is better.
Max tip age was introduced in #5987 to make it possible to run
testnet-in-a-box. But associating this behavior with the testnet chain
is wrong conceptually, as it is not needed in normal usage.
Should aim to make testnet test the software as-is.
Replace it with a (debug) option `-maxtipage`, which can be
specified only in the specific case.

We used to have a trickle node, a node which was chosen in each iteration of
the send loop that was privileged and allowed to send out queued up non-time
critical messages. Since the removal of the fixed sleeps in the network code,
this resulted in fast and attackable treatment of such broadcasts.
This pull request changes the 3 remaining trickle use cases by random delays:
* Local address broadcast (while also removing the the wiping of the seen filter)
* Address relay
* Inv relay (for transactions; blocks are always relayed immediately)
The code is based on older commits by Patrick Strateman.
- Avoids string typos (by making the compiler check)
- Makes it easier to grep for handling/generation of a certain message type
- Refer directly to documentation by following the symbol in IDE
- Move list of valid message types to protocol.cpp:
protocol.cpp is a more appropriate place for this, and having
the array there makes it easier to keep things consistent.

Some extra bytes in libconsensus to get all the crypto (except for signing, which is in the common module) below the libconsensus future independent repo (that has libsecp256k1 as a subtree).
hmac_sha256.o seems to be the only thing libbitcoinconsensus doesn't depend on from crypto, some more bytes for the final libconsensus: I'm not personally worried.
A further pass over the available inputs has been added to ApproximateBestSubset after a candidate set has been found. It will prune any extraneous inputs in the selected subset, in order to decrease the number of input and the resulting change.
Mempool requests use a fair amount of bandwidth when the mempool is large,
disconnecting peers using them follows the same logic as disconnecting
peers fetching historical blocks.

One test in AcceptToMemoryPool was to compare a transaction's fee
agains the value returned by GetMinRelayFee. This value was zero for
all small transactions. For larger transactions (between
DEFAULT_BLOCK_PRIORITY_SIZE and MAX_STANDARD_TX_SIZE), this function
was preventing low fee transactions from ever being accepted.
With this function removed, we will now allow transactions in that range
with fees (including modifications via PrioritiseTransaction) below
the minRelayTxFee, provided that they have sufficient priority.
Redo the feerate index to be based on mining score, rather than fee.
Update mempool_packages.py to test prioritisetransaction's effect on
package scores.
- Add new translations (finally, after a long time)
- update-translation script was not considering new translations - oops
- fixed this, also remove (nearly) empty translations
- Update translation process, it was still describing the old repository
structure
Use the score index on the mempool to only add sorted txs in order. Remove much of the validation while building the block, relying on mempool to be consistent and only contain txs that can be mined.
The mempool is assumed to be consistent as far as not containing txs which spend non-existent outputs or double spends, and scripts are valid. Finality of txs is still checked (except not coinbase maturity, assumed in mempool).
Still TestBlockValidity in case mempool consistency breaks and return error state if an invalid block was created.
Unit tests are modified to realize that invalid blocks can now be constructed if the mempool breaks its consistency assumptions and also updated to have the right fees, since the cached value is now used for block construction.
Conflicts:
src/miner.cpp
The score index is meant to represent the order of priority for being included in a block for miners. Initially this is set to the transactions modified (by any feeDelta) fee rate. Index improvements and unit tests by sdaftuar.
Store sum of legacy and P2SH sig op counts. This is calculated in AcceptToMemory pool and storing it saves redoing the expensive calculation in block template creation.
But keep translating them in the GUI.
This - necessarily - requires duplication of a few messages.
Alternative take on #7134, that keeps the translations from being wiped.
Also document GetWarnings() input argument.
Fixes#5895.

Mruset setInventoryKnown was reduced to a remarkably small 1000
entries as a side effect of sendbuffer size reductions in 2012.
This removes setInventoryKnown filtering from merkleBlock responses
because false positives there are especially unattractive and
also because I'm not sure if there aren't race conditions around
the relay pool that would cause some transactions there to
be suppressed. (Also, ProcessGetData was accessing
setInventoryKnown without taking the required lock.)
This replaces using inv messages to announce new blocks, when a peer requests
(via the new "sendheaders" message) that blocks be announced with headers
instead of inv's.
Since headers-first was introduced, peers send getheaders messages in response
to an inv, which requires generating a block locator that is large compared to
the size of the header being requested, and requires an extra round-trip before
a reorg can be relayed. Save time by tracking headers that a peer is likely to
know about, and send a headers chain that would connect to a peer's known
headers, unless the chain would be too big, in which case we revert to sending
an inv instead.
Based off of @sipa's commit to announce all blocks in a reorg via inv,
which has been squashed into this commit.

This allows for much finer control of the transaction fees per kilobyte
as it prevent small transactions using a fee that is more appropriate
for one that is of a kilobyte.
This also allows controlling the fee per kilobyte over rpc such that:
bitcoin-cli settxfee `bitcoin-cli estimatefee 2`
would make sense, while currently it grossly fails often by a factor of x3
For each 'bit' in the filter we really maintain 2 bits, which store either:
0: not set
1-3: set in generation N
After (nElements / 2) insertions, we switch to a new generation, and wipe
entries which already had the new generation number, effectively switching
from the last 1.5 * nElements set to the last 1.0 * nElements set.
This is 25% more space efficient than the previous implementation, and can
(at peak) store 1.5 times the requested amount of history (though only
1.0 times the requested history is guaranteed).
The existing unit tests should be sufficient.
This switches the Merkle tree logic for blocks to one that runs in constant (small) space.
The old code is moved to tests, and a new test is added that for various combinations of
block sizes, transaction positions to compute a branch for, and mutations:
* Verifies that the old code and new code agree for the Merkle root.
* Verifies that the old code and new code agree for the Merkle branch.
* Verifies that the computed Merkle branch is valid.
* Verifies that mutations don't change the Merkle root.
* Verifies that mutations are correctly detected.

This makes sure that retransmits by a whitelisted peer also actually
result in a retransmit.
Further, this changes the logic to never relay in case we would assign
a DoS score, as we expect to get DoS banned ourselves as a result.
Adds 127.0.0.1:9050 for the .onion proxy if we can succesfully connect
to the control port.
Natural followup to creating hidden services automatically.
Previously all of these functions could return negative values (for different
readons). Large portions of the codebase currently assume that these
functions return positive values.
Previously peers which implement a protocol version less than NO_BLOOM_VERSION
would not be disconnected for sending a filter command, regardless of the
peerbloomfilter option.
Many node operators do not wish to provide expensive bloom filtering for SPV
clients, previously they had to cherry pick the commit which enabled the
disconnect logic.
The default should remain false until a sufficient percent of SPV clients
have updated.
