The old Bitcoin alert system has long since been retired.
( See also: https://bitcoin.org/en/alert/2016-11-01-alert-retirement )
This change causes each node to send any old peers that
it connects with a copy of the final alert.
The alert it hardcode cancels all other alerts including
other final alerts.
376b3c2 Make the cs_sendProcessing a LOCK instead of a TRY_LOCK (Matt Corallo)
d7c58ad Split CNode::cs_vSend: message processing and message sending (Matt Corallo)
This command allows a user to increase the fee on a wallet transaction T, creating a "bumper" transaction B.
T must signal that it is BIP-125 replaceable.
T's change output is decremented to pay the additional fee. (B will not add inputs to T.)
T cannot have any descendant transactions.
Once B bumps T, neither T nor B's outputs can be spent until either T or (more likely) B is mined.
Includes code by @jonasschnelli and @ryanofsky
This forces the message handling thread to make another full
iteration of SendMessages prior to going back to sleep, ensuring
we announce the new block to all peers before sleeping.

Technically cs_sendProcessing is entirely useless now because it
is only ever taken on the one MessageHandler thread, but because
there may be multiple of those in the future, it is left in place
cs_vSend is used for two purposes - to lock the datastructures used
to queue messages to place on the wire and to only call
SendMessages once at a time per-node. I believe SendMessages used
to access some of the vSendMsg stuff, but it doesn't anymore, so
these locks do not need to be on the same mutex, and also make
deadlocking much more likely.

This disentangles the script validation skipping from checkpoints.
A new option is introduced "assumevalid" which specifies a block whos
ancestors we assume all have valid scriptsigs and so we do not check
them when they are also burried under the best header by two weeks
worth of work.
Unlike checkpoints this has no influence on consensus unless you set
it to a block with an invalid history. Because of this it can be
easily be updated without risk of influencing the network consensus.
This results in a massive IBD speedup.
This approach was independently recommended by Peter Todd and Luke-Jr
since POW based signature skipping (see PR#9180) does not have the
verifiable properties of a specific hash and may create bad incentives.
The downside is that, like checkpoints, the defaults bitrot and older
releases will sync slower. On the plus side users can provide their
own value here, and if they set it to something crazy all that will
happen is more time will be spend validating signatures.
Checkblocks and checklevel are also moved to the hidden debug options:
Especially now that checkblocks has a low default there is little need
to change these settings, and users frequently misunderstand them as
influencing security or IBD speed. By hiding them we offset the
space added by this new option.
vRecvMsg is now only touched by the socket handler thread.
The accounting vars (nRecvBytes/nLastRecv/mapRecvBytesPerMsgCmd) are also
only used by the socket handler thread, with the exception of queries from
rpc/gui. These accesses are not threadsafe, but they never were. This needs to
be addressed separately.
Also, update comment describing data flow
Similar to the recv flag, but this one indicates whether or not the net's send
buffer is full.
The socket handler checks the send queue when a new message is added and pauses
if necessary, and possibly unpauses after each message is drained from its buffer.
Messages are dumped very quickly from the socket handler to the processor, so
it's the depth of the processing queue that's interesting.
The socket handler checks the process queue's size during the brief message
hand-off and pauses if necessary, and the processor possibly unpauses each time
a message is popped off of its queue.
In order to sleep accurately, the message handler needs to know if _any_ node
has more processing that it should do before the entire thread sleeps.
Rather than returning a value that represents whether ProcessMessages
encountered a message that should trigger a disconnnect, interpret the return
value as whether or not that node has more work to do.
Also, use a global fProcessWake value that can be set by other threads,
which takes precedence (for one cycle) over the messagehandler's decision.
Note that the previous behavior was to only process one message per loop
(except in the case of a bad checksum or invalid header). That was changed in
PR #3180.
The only change here in that regard is that the current node now falls to the
back of the processing queue for the bad checksum/invalid header cases.
In spite of the name FindLatestBefore used std::lower_bound to try
to find the earliest block with a nTime greater or equal to the
the requested value. But lower_bound uses bisection and requires
the input to be ordered with respect to the comparison operation.
Block times are not well ordered.
I don't know what lower_bound is permitted to do when the data
is not sufficiently ordered, but it's probably not good.
(I could construct an implementation which would infinite loop...)
To resolve the issue this commit introduces a maximum-so-far to the
block indexes and searches that.
For clarity the function is renamed to reflect what it actually does.
An issue that remains is that there is no grace period in importmulti:
If a address is created at time T and a send is immediately broadcast
and included by a miner with a slow clock there may not yet have been
any block with at least time T.
The normal rescan has a grace period of 7200 seconds, but importmulti
does not.

There is still a call to ActivateBestChain with cs_main if a peer
requests the block prior to it being validated, but this one is
more specifically-gated, so should be less of an issue.
AcceptToMemoryPool has several classes of return false statements.
- return state.Invalid or state.DoS directly itself
- return false and set fMissingInputs (state is valid)
- return false and state is set by failed CheckTransaction
- return false and state is set by failed CheckInputs.
This commit patches the last case where the state variable was reused for additional calls to CheckInputs to identify witness stripping as cause of validation failure. After this commit, it should be the case that if !fMissingInputs, state is always Invalid if AcceptToMemoryPool returns false.

20449ef Don't overpay fee if we have selected new coins that result in a smaller transaction. (Alex Morcos)

032ba3f RPC help documentation for addnode peerinfo. (Gregory Maxwell)
90f13e1 Add release notes for addnode changes. (Gregory Maxwell)
50bd12c Break addnode out from the outbound connection limits. (Gregory Maxwell)
On repeated calls to SelectCoins we try to meet the fee necessary for the last transaction, the new fee required might be smaller, so increase our change by the difference if we can.
Once we've picked coins and dummy-signed the transaction to calculate fee, if we don't have sufficient fee, then try to meet the fee by reducing change before resorting to picking new coins.
Previously addnodes were in competition with outbound connections
for access to the eight outbound slots.
One result of this is that frequently a node with several addnode
configured peers would end up connected to none of them, because
while the addnode loop was in its two minute sleep the automatic
connection logic would fill any free slots with random peers.
This is particularly unwelcome to users trying to maintain links
to specific nodes for fast block relay or purposes.
Another result is that a group of nine or more nodes which are
have addnode configured towards each other can become partitioned
from the public network.
This commit introduces a new limit of eight connections just for
addnode peers which is not subject to any of the other connection
limitations (including maxconnections).
The choice of eight is sufficient so that under no condition would
a user find themselves connected to fewer addnoded peers than
previously. It is also low enough that users who are confused
about the significance of more connections and have gotten too
copy-and-paste happy will not consume more than twice the slot
usage of a typical user.
Any additional load on the network resulting from this will likely
be offset by a reduction in users applying even more wasteful
workaround for the prior behavior.
The retry delays are reduced to avoid nodes sitting around without
their added peers up, but are still sufficient to prevent overly
aggressive repeated connections. The reduced delays also make
the system much more responsive to the addnode RPC.
Ban-disconnects are also exempted for peers added via addnode since
the outbound addnode logic ignores bans. Previously it would ban
an addnode then immediately reconnect to it.
A minor change was also made to CSemaphoreGrant so that it is
possible to re-acquire via an object whos grant was moved.
Performing signing in the inner loop has terrible performance
when many passes through are needed to complete the selection.
Signing before the algorithm is complete also gets in the way
of correctly setting the fee (e.g. preventing over-payment when
the fee required goes down on the final selection.)
Use of the dummy might overpay on the signatures by a couple bytes
in uncommon cases where the signatures' DER encoding is smaller
than the dummy: Who cares?
In order to do this, we must call ActivateBestChain prior to
responding getdata requests for blocks which we announced using
compact blocks.
For getheaders responses we dont need code changes, but do note
that we must reset the bestHeaderSent so that the SendMessages call
re-announces the header in question.
While we could do something smarter for getblocks, calling
ActivateBestChain is simple and more obviously correct, instead of
doing something more similar to getheaders.

The meaning is clear from the context, and we're inconsistent here.

The [JSON-RPC specification](http://www.jsonrpc.org/specification) allows passing parameters as an Array, for by-position
arguments, or an Object, for by-name arguments.
This implements by-name arguments, but preserves full backwards compatibility. API using by-name arguments are
easier to extend, and easier to use (no need to guess which argument goes where).
Named are mapped to positions by a per-call structure, provided through the RPC command table.
Missing arguments will be replaced by null, except if at the end, then the argument is left out completely.
Currently calls fail (though not crash) on intermediate nulls, but this should be improved on a per-call basis later.

Make a more conservative notion of whether the node is caught up to the rest of the network and only count transactions as fee estimation data points if the node is caught up.
All decisions about whether the transactions are valid data points are made at the time the transaction arrives. Updating on blocks all the time will now cause stale fee estimates to decay quickly when we restart a node.
Fee estimation can just check its own mapMemPoolTxs to determine the same information. Note that now fee estimation for block processing must happen before those transactions are removed, but this shoudl be a speedup.
This was an oversight, where blocks and mempool tracking were ignored during IBD, but transactions that arrived during IBD but were included in blocks after IBD were not ignored.
Once priority estimation was removed, not all transactions in the mempool are tracked in the fee estimation mempool tracking. So there is no error if a transaction is not found for removal.
We were marking coins FRESH before being sure they were not overwriting dirty undo data. This condition was never reached in existing code because undo data was always flushed before UpdateCoins was called with new transactions, but could have been exposed in an otherwise safe refactor.
Clarify in the comments the assumptions made in ModifyNewCoins.
Add ability to undo transactions to UpdateCoins unit test.
Thanks to Russ Yanofsky for suggestion on how to make logic clearer and fixing up the ccoins_modify_new test cases.
Surprisingly this hasn't been causing me any issues while testing, probably
because it requires lots of large blocks to be flying around.

If the mempool is not completely full, treat the difference between
the maximum size and the actual usage as available for the coin cache.
This also changes the early flush trigger from (usage > 0.9 * space)
to (usage > 0.9 * space && usage > space - 100MB). This means we're not
permanently leaving 10% of the space unused when the space is large.

297cc20 qt: layoutAboutToChange signal is called layoutAboutToBeChanged (Wladimir J. van der Laan)
This resolves an issue where a wallet transaction which failed to
relay previously because it couldn't make it into the mempool
will not try again until restart, even though mempool conditions
may have changed.
Abandoned and known-conflicted transactions are skipped.
Some concern was expressed that there may be users with many
unknown conflicts would waste a lot of CPU time trying to
add them to their memory pools over and over again. But I am
doubtful these users exist in any number, if they do exist
they have worse problems, and they can mitigate any performance
issue this might have by abandoning the transactions in question.
This is another violation of the one definition rule, as the type
for mapOrphanTransactionsByPrev did not match the one in
net_processing.cpp anymore. As it now depends on a custom Iterator,
it seems too much hassle to correctly expose it to the tests.
Instead, this commit just removes the one test it was referenced in.
Add more comprehensive unit tests for CCoinsViewCache. Right now it is hard to
refactor caching code or fix bugs in the caching logic because you have to try
to mentally enumerate all the different states the cache might be in to make
sure a change doesn't cause unintended consequences. The new tests explicitly
enumerate relevant cache states, documenting and verifying the behavior in each
state, so it will be safer and easier to make changes to the caching code in
the future.

Sorry for the churn on this, but the current message (introduced in #9073)
isn't acceptable:
$ src/bitcoin-cli getinfo
rpc: couldn't connect to server
(make sure server is running and you are connecting to the correct RPC port: -1 unknown)
Putting the error code after the words "RPC port" made me wonder whether
there was a port configuration issue.
This changes it to:
$ src/bitcoin-cli getinfo
error: couldn't connect to server: unknown (code -1)
(make sure server is running and you are connecting to the correct RPC port)
As orphan state is now "network state", like in
d6ea737be1,
UnloadBlockIndex is only used during init if we end up reindexing
to clear our block state so that we can start over. However, at
that time no connections have been brought up as CConnman hasn't
been started yet, so all of the network processing state logic is
empty when its called.

that will come with ed25519 keys, until it does, we depend on the old
hidden service type so make this explicit.
See #9214.

fedea8a net: don't send any messages before handshake or after requested disconnect (Cory Fields)
d74e352 net: Set feelers to disconnect at the end of the version message (Cory Fields)
This fixes one of the last major layer violations in the networking stack.
The network side is no longer in charge of message serialization, so it is now
decoupled from Bitcoin structures. Only the header is serialized and attached
to the payload.
CVectorWriter is useful for overwriting or appending an existing byte vector.
CNetMsgMaker is a shortcut for creating messages on-the-fly which are suitable
for pushing to CConnman.

Also, send reject messages earlier in SendMessages(), so that disconnections are
processed earlier.
These changes combined should ensure that no message is ever sent after
fDisconnect is set.
This way we're not relying on messages going out after fDisconnect has been
set.
This should not cause any real behavioral changes, though feelers should
arguably disconnect earlier in the process. That can be addressed in a later
functional change.

Make splash screen queue its own deletion when it receives the finished
command, instead of relying on WA_DeleteOnClose which doesn't work under
these circumstances.
Make ownership of the QThread object clear, so that the RPCConsole
can wait for the executor thread to quit before shutdown is called. This
increases overall thread safety, and prevents some objects from leaking
on exit.
None of these are very serious, and are leaks in objects that are
created at most one time.
In most cases this means properly using the QObject parent hierarchy,
except for BanTablePriv/PeerTablePriv which are not QObject,
so use a std::unique_ptr instead.
f004e67 Minor change to comment above new NODE_WITNESS service flag to keep it consitent with existing comment structure. Helps with readability. (Greg Walker)
Make sure that the count is a zero modulo the new mask before
scaling, otherwise the next time until a measure triggers
will take only 1/2 as long as accounted for. This caused
the 'min time' to be potentially off by as much as 100%.
When a BIP152 HB-mode peer is in the least preferred position and
disconnects, they will not be by ForNode on the next loop. They
will continue to sit in that position and prevent deactivating
HB mode for peers that are still connected.
There is no reason for them to stay in the list if already gone,
so drop the first element unconditionally if there are too many.
Fixes issue #9163.

d768f15 [qa] Make comptool push blocks instead of relying on inv-fetch (mrbandrews)
- Do sorting for date, amount and confirmations column as longlong, not
unsigned longlong.
- Use `UserRole` to store our own data. This makes it treated as
ancillary data prevents it from being displayed.
- Get rid of `getMappedColumn` `strPad` - these are no longer necessary.
- Get rid of hidden `_INT64` columns.
- Start enumeration from 0 (otherwise values are undefined).
In 0.13 orphan transactions began being treated as implicit
INVs for their parents. But the resulting getdata were
not getting the witness flag.
This fixes issue #9182 reported by chjj and roasbeef on IRC.
Make a copy of the boost time-point to wait for, otherwise the head of
the queue may be deleted by another thread while this one is waiting,
while the boost function still has a reference to it.
Although this problem is in non-test code, this is not an actual problem
outside of the tests because we use the thread scheduler with only one
service thread, so there will never be threads fighting at the head of
the queue.
The old boost fallback escapes this problem because it passes a scalar
value to wait_until instead of a const object reference.
Found by running the tests in LLVM-4.0-master asan.
This further decouples "main" and "net" processing logic by moving
orphan processing out of the chain-connecting cs_main lock and
into its own cs_main lock, beside all of the other chain callbacks.
Once further decoupling of net and main processing logic occurs,
orphan handing should move to its own lock, out of cs_main.
Note that this will introduce a race if there are any cases where
we assume the orphan map to be consistent with the current chain
tip, however I am confident there is no such case (ATMP will fail
without DoS score in all such cases).

c93beac [qa] Test that invalid compactblocks don't result in ban (Suhas Daftuar)
Dbwrapper used GetSerializeSize() to compute the size of the buffer
to preallocate. For some cases (specifically: CCoins) this requires
a costly compression call. Avoid this by just using fixed size
preallocations instead.
To get the advantages of faster GetSerializeSize() implementations
back that were removed in "Make GetSerializeSize a wrapper on top of
CSizeComputer", reintroduce them in the few places in the form of a
specialized Serialize() implementation. This actually gets us in a
better state than before, as these even get used when they're invoked
indirectly in the serialization of another object.
The CSerAction's ForRead() method does not depend on any runtime
data, so guarantee that requests to it can be optimized out by
making it constexpr.
Suggested by Cory Fields.
Remove the nType and nVersion as parameters to all serialization methods
and functions. There is only one place where it's read and has an impact
(in CAddress), and even there it does not impact any of the recursively
invoked serializers.
Instead, the few places that need nType or nVersion are changed to read
it directly from the stream object, through GetType() and GetVersion()
methods which are added to all stream classes.
Given that in default GetSerializeSize implementations created by
ADD_SERIALIZE_METHODS we're already using CSizeComputer(), get rid
of the specialized GetSerializeSize methods everywhere, and just use
CSizeComputer. This removes a lot of code which isn't actually used
anywhere.
For CCompactSize and CVarInt this actually removes a more efficient
size computing algorithm, which is brought back in a later commit.
The current getblocktxn implementation drops and ignores requests for old
blocks, which causes occasional sync_block timeouts during the
p2p-compactblocks.py test as reported in
https://github.com/bitcoin/bitcoin/issues/8842.
The p2p-compactblocks.py test setup creates many new blocks in a short
period of time, which can lead to getblocktxn requests for blocks below the
hardcoded depth limit of 10 blocks. This commit changes the getblocktxn
handler not to ignore these requests, so the peer nodes in the test setup
will reliably be able to sync.
The protocol change is documented in BIP-152 update "Allow block responses
to getblocktxn requests" at https://github.com/bitcoin/bips/pull/469.
The protocol change is not expected to affect nodes running outside the test
environment, because there shouldn't normally be lots of new blocks being
rapidly added that need to be synced.
The stream implementations had two cascading layers (the upper one
with operator<< and operator>>, and a lower one with read and write).
The lower layer's functions are never cascaded (nor should they, as
they should only be used from the higher layer), so make them return
void instead.

- `--help`, `--version` etc should exit with `0` i.e. no error ("not enough args" case should still trigger an error)
- error reading config file should exit with `1`
Slightly refactor AppInitRPC/AppInitRawTx to return standard exit codes (EXIT_FAILURE/EXIT_SUCCESS) or CONTINUE_EXECUTION (-1)
The changes here are dense and subtle, but hopefully all is more explicit
than before.
- CConnman is now in charge of sending data rather than the nodes themselves.
This is necessary because many decisions need to be made with all nodes in
mind, and a model that requires the nodes calling up to their manager quickly
turns to spaghetti.
- The per-node-serializer (ssSend) has been replaced with a (quasi-)const
send-version. Since the send version for serialization can only change once
per connection, we now explicitly tag messages with INIT_PROTO_VERSION if
they are sent before the handshake. With this done, there's no need to lock
for access to nSendVersion.
Also, a new stream is used for each message, so there's no need to lock
during the serialization process.
- This takes care of accounting for optimistic sends, so the
nOptimisticBytesWritten hack can be removed.
- -dropmessagestest and -fuzzmessagestest have not been preserved, as I suspect
they haven't been used in years.
This allows future software that would relay compact blocks before
full validation to announce only to peers that will not ban if the
block turns out to be invalid.
