This was a long-standing and annoying problem.
If autogen.sh was not manually run after touching configure.ac,
bitcoin-config.h would not be properly regenerated. This causes very subtle
problems when configure appears to enable a new value, but it does not end up
reflected in the build.

This removes another callback from block connection logic, making it
easier to reason about the wallet-RPCs-returns-stale-info issue.
UpdatedTransaction was previously used by the GUI to display
coinbase transactions only after they have a block built on top of
them. This worked fine for in most cases, but only worked due to a
corner case if the user received a coinbase payout in a block
immediately prior to restart. In that case, the normal process of
caching the most recent coinbase transaction's hash would not work,
and instead it would only work because of the on-load -checkblocks
calling DisconnectBlock and ConnectBlock on the current tip.
In order to make this more robust, a full mapWallet loop after the
first block which is connected after restart was added.

This simplifies fixing the wallet-returns-stale-info issue as we
can now hold cs_wallet across an entire block instead of only
per-tx (though we only actually do so in the next commit).
This change also removes the NOT_IN_BLOCK constant in favor of only
passing the CBlockIndex* parameter to SyncTransactions when a new
block is being connected, instead of also when a block is being
disconnected.
This change adds a parameter to BlockConnectedDisconnected which
lists the transactions which were removed from mempool due to
confliction as a result of this operation. While its somewhat of a
shame to make block-validation-logic generate a list of mempool
changes to be included in its generated callbacks, fixing this isnt
too hard.
Further in this change-set, CValidationInterface starts listening
to mempool directly, placing it in the middle and giving it a bit
of logic to know how to route notifications from block-validation,
mempool, etc (though not listening for conflicted-removals yet).

This changes the logging categories to boolean flags instead of strings.
This simplifies the acceptance testing by avoiding accessing a scoped
static thread local pointer to a thread local set of strings. It
eliminates the only use of boost::thread_specific_ptr outside of
lockorder debugging.
This change allows log entries to be directed to multiple categories
and makes it easy to change the logging flags at runtime (e.g. via
an RPC, though that isn't done by this commit.)
It also eliminates the fDebug global.
Configuration of unknown logging categories now produces a warning.
Since we are more accurately measuring pcoinsTip peak usage at twice the current in dynamic usage, it makes sense to double the default (this will lead to the same effective usage and peak usage as previously).
We should also double the buffer used to avoid flushing if above 90% but still sufficient space remaining.

e141aa4 Add mallocinfo mode to `getmemoryinfo` RPC (Wladimir J. van der Laan)
Tree-SHA512: e778631765c29b3b5fb94eb66e5f50a8f108a234891bdcc4883f1e6e2fdd223f7660fad987eb2d7cbda5b800482d78adc1a309a3f6f83a84c556af43ebee2ed7
This adds a mode argument to `getmemoryinfo`. By default the output
will remain the same. However if a mode argument of `mallocinfo` is
provided the result of glibc `malloc_info` (if available) will
be returned as a string, as-is.
This is useful for tracking heap usage over time or troubleshooting
memory fragmentation issues.

Instead of having an exception propagate into the program when an

We previously would block waiting for a CSemaphoreGrant in
ThreadOpenAddedConnections, when we did not need to. This would
block as the posts in CConnman shutdown were both to the wrong
semaphore and in the wrong location.
RPC_INVALID_REQUEST and RPC_METHOD_NOT_FOUND are mapped internally to
HTTP error codes and should not be used for application-layer errors.
This commit adds commenting around those definitions to warn not to use
them for application errors.
On msvc14, int literal '-2147483648' is invalid, because '2147483648' is unsigned type and cant't apply minus operator to unsigned type.
To define the int literal correctly, use '-2147483647 - 1' formula that is also used to define INT_MIN in limits.h.
The fundrawtransaction() RPC was returning misleading or incorrect error
codes (for example RPC_INTERNAL_ERROR when funding the transaction
failed). This commit fixes those error codes:
- RPC_INTERNAL_ERROR should not be returned for application-level
errors, only for genuine internal errors such as corrupted data.
That error code has been replaced with RPC_WALLET_ERROR.
This commit also updates the test cases to explicitly test the error code.
The setban() RPC was returning misleading or incorrect error
codes (for example RPC_CLIENT_NODE_ALREADY_ADDED when an invalid IP
address was entered). This commit fixes those error codes:
- RPC_CLIENT_INVALID_IP_OR_SUBNET should be returned if the client
enters an invalid IP address or subnet.
This commit also updates the test cases to explicitly test the error code.
This commit also adds a testcase for trying to setban on an invalid subnet.
The removeprunedfunds() RPC was returning misleading or incorrect error
codes (for example RPC_INTERNAL_ERROR when the transaction was
not found in the wallet). This commit fixes those error codes:
- RPC_INTERNAL_ERROR should not be returned for application-level
errors, only for genuine internal errors such as corrupted data.
This error code has been replaced with RPC_WALLET_ERROR.
This commit also updates the test cases to explicitly test the error code.
RPCs in blockchain.cpp were returning misleading or incorrect error
codes (for example getblock() returning RPC_INTERNAL_ERROR when the
block had been pruned). This commit fixes those error codes:
- RPC_INTERNAL_ERROR should not be returned for application-level
errors, only for genuine internal errors such as corrupted data.
- RPC_METHOD_NOT_FOUND should not be returned in response to a
JSON request for an existing method.
Those error codes have been replaced with RPC_MISC_ERROR or
RPC_INVALID_PARAMETER as appropriate.
The bumpfee() RPC was returning misleading or incorrect error codes
(for example RPC_INVALID_ADDRESS_OR_KEY when the transaction was not
BIP125 replacable). This commit fixes those error codes:
- RPC_INVALID_ADDRESS_OR_KEY if an invalid address was provided:
- Invalid change address given
- RPC_INVALID_PARAMETER if a single (non-address/key) parameter is incorrect
- confTarget and totalFee options should not both be set.
- Invalid confTarget
- Insufficient totalFee (cannot be less than required fee)
- RPC_WALLET_ERROR for any other error
- Transaction has descendants in the wallet
- Transaction has descendants in the mempool
- Transaction has been mined, or is conflicted with a mined transaction
- Transaction is not BIP 125 replaceable
- Transaction has already been bumped
- Transaction contains inputs that don't belong to the wallet
- Transaction has multiple change outputs
- Transaction does not have a change output
- Fee is higher than maxTxFee
- New fee rate is less than the minimum fee rate
- Change output is too small.
This commit also updates the test cases to explicitly test the error code.
On msvc14, the compiler error C4146 (unary minus operator applied to unsigned type, result still unsigned) had been occured.

`u_int` is not available on some platforms (not sure what standard it's
supposed to be part of), we don't use it anywhere else, and it doesn't
hurt to simply write `unsigned int` out here.
Define MSG_DONTWAIT and MSG_NO_SIGNAL in the implementation files that
use them (`net.cpp` and `netbase.cpp`), instead of compat.h which is
included all over the place.
This avoids putting them in the global namespace, as defining them as 0
is a hack that works for our specific usage, but it is not a general
solution.
Also makes sure they are defined only once so the `!defined(MSG_x)` guard can go.
Instead of the WIN32-specific workaround, detect lack of `MSG_DONTWAIT`
in the build system. This allows other platforms without `MSG_DONTWAIT`
to work too.
Setting minrelaytxfee to 0 will allow all transactions regardless of fee to enter your mempool until it reaches its size limit. However now that mempool limiting is governed by a separate incrementalrelay fee, it is an unnecessary restriction to prevent a minrelaytxfee of 0.
This a breaking API change to the prioritisetransaction RPC call which previously required exactly three arguments and now requires exactly two (hash and feeDelta). The function prioritiseTransaction is also updated.
"startingpriority" and "currentpriority" are no longer returned in the JSON information about a mempool entry. This affects getmempoolancestors, getmempooldescendants, getmempooolentry, and getrawmempool.
Remove -limitfreerelay and always enforce minRelayTxFee in the mempool (except from disconnected blocks)
Remove -relaypriority, the option was only used for the ability to allow free transactions to be relayed regardless of their priority. Both notions no longer apply.
Previously if an existing watch only key was reimported with a new timestamp,
the new timestamp would not be saved in the key metadata, and would not be used
to update the wallet nTimeFirstKey value (which could cause rescanning to start
at the wrong point and miss transactions).

Change ScanForWalletTransactions return value so it is possible to distinguish
scans that skip reading every block (due to the nTimeFirstKey optimization)
from scans that fail while reading the chainActive.Tip() block. Return value is
now non-null in the non-failing case.
This change doesn't affect any user-visible behavior, it is only an internal
API improvement. The only code currently using the ScanForWalletTransactions
return value is in importmulti, and importmulti always calls
ScanForWalletTransactions with a pindex pointing to the first block in
chainActive whose block time is >= (nLowestTimestamp - 7200), while
ScanForWalletTransactions would only return null without reading blocks when
pindex and every block after it had a block time < (nTimeFirstKey - 7200).
These conditions could never happen at the same time because nTimeFirstKey <=
nLowestTimestamp.
I'm planning to make a more substantial API improvement in the future (making
ScanForWalletTransactions private and exposing a higher level rescan method to
RPC code), but Matt Corallo <git@bluematt.me> pointed out this odd behavior
introduced by e2e2f4c "Return errors from importmulti if complete rescans are
not successful" yesterday, so I'm following up now to get rid of badness
introduced by that merge.
Prior to this commit pindexRescan was initialized to a chainActive.Tip().
However, the value of pindexRescan set at time of initialization was never
read before pindexRescan was being set to either chainActive.Genesis()
(case 1), FindForkInGlobalIndex(chainActive, locator) (case 2) or
chainActive.Genesis() (case 3). Thus, the initialization was redundant.
This commit a.) removes the redundant initialization and b.) simplifies
this logic so that pindexRescan is initialized to chainActive.Genesis()
(case 1 and 3), and set to FindForkInGlobalIndex(chainActive, locator)
(case 2) as needed.
In the case that the branch ...
if (itInFlight != mapBlocksInFlight.end() && itInFlight->second.first == nodeid) {
... is taken, there was prior to this commit an implicit assumption that
MarkBlockAsInFlight(...) was being called with its fifth and optional
argument (pit) being present (and non-NULL).

This removes the option from the wallet to not pay a fee on "small"
transactions which spend "old" inputs.
This code is no longer worth keeping around, as almost all miners
prefer not to include transactions which pay no fee at all.
Use of `sprintf` is seen as a red flag as many of its uses are insecure.
OpenBSD warns about it while compiling, and some modern platforms, e.g.
[cloudlibc from cloudabi](https://github.com/NuxiNL/cloudlibc) don't
even provide it anymore.
Although our uses of these functions are secure, it can't hurt to
replace them anyway. There are only 3 occurences left, all in the
tests.
- Change initializeResult(int) to initializeResult(bool) to avoid
implicit type conversion.
- Use EXIT_FAILURE and EXIT_SUCCESS instead of magic numbers.
- Remove the argument from shutdownResult(int); it was called with a
constant argument.

CWallet wallet;
An effort to reduce the size of AppInitMain().
The removed code upgrades the location of the block files when
upgrading to 0.8. 0.8 seems to be the oldest version still in use.
If the code was compiled with newer (>=3.17) kernel headers but executed
on a system without the system call, every use of random would crash the
program. Add a fallback for that case.
Move the OS random test to a sanity check function that is called every
time bitcoind is initialized.
Keep `src/test/random_tests.cpp` for the case that later random tests
are added, and keep a rudimentary test that just calls the sanity check.
These are available in sandboxes without access to files or
devices. Also [they are safer and more straightforward](https://en.wikipedia.org/wiki/Entropy-supplying_system_calls)
to use than `/dev/urandom` as reading from a file has quite a few edge
cases:
- Linux: `getrandom(buf, buflen, 0)`. [getrandom(2)](http://man7.org/linux/man-pages/man2/getrandom.2.html)
was introduced in version 3.17 of the Linux kernel.
- OpenBSD: `getentropy(buf, buflen)`. The [getentropy(2)](http://man.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man2/getentropy.2)
function appeared in OpenBSD 5.6.
- FreeBSD and NetBSD: `sysctl(KERN_ARND)`. Not sure when this was added
but it has existed for quite a while.
Alternatives:
- Linux has sysctl `CTL_KERN` / `KERN_RANDOM` / `RANDOM_UUID`
which gives 16 bytes of randomness. This may be available
on older kernels, however [sysctl is deprecated on Linux](https://lwn.net/Articles/605392/)
and even removed in some distros so we shouldn't use it.
Add tests for `GetOSRand()`:
- Test that no error happens (otherwise `RandFailure()` which aborts)
- Test that all 32 bytes are overwritten (initialize with zeros, try multiple times)
Discussion:
- When to use these? Currently they are always used when available.
Another option would be to use them only when `/dev/urandom` is not
available. But this would mean these code paths receive less testing,
and I'm not sure there is any reason to prefer `/dev/urandom`.

methods missing it. I chose the second.

7a8c251901 made this logic hard to follow. After that change, messages would
not be sent to a peer via SendMessages() before the handshake was complete, but
messages could still be sent as a response to an incoming message.
For example, if a peer had not yet sent a verack, we wouldn't notify it about
new blocks, but we would respond to a PING with a PONG.
This change makes the behavior straightforward: until we've received a verack,
never send any message other than version/verack/reject.
The behavior until a VERACK is received has always been undefined, this change
just tightens our policy.
This also makes testing much easier, because we can now connect but not send
version/verack, and anything sent to us is an error.
Prior to this change, all messages were ignored until a VERSION message was
received, as well as possibly incurring a ban score.
Since REJECT messages can be sent at any time (including as a response to a bad
VERSION message), make sure to always parse them.
Moving this parsing up keeps it from being caught in the
if (pfrom->nVersion == 0) check below.
7a8c251901 made a change to avoid getting into SendMessages() until the
version handshake (VERSION + VERACK) is complete. That was done to avoid
leaking out messages to nodes who could connect, but never bothered sending
us their version/verack.
Unfortunately, the ban tally and possible disconnect are done as part of
SendMessages(). So after 7a8c251901, if a peer managed to do something
bannable before completing the handshake (say send 100 non-version messages
before their version), they wouldn't actually end up getting
disconnected/banned. That's fixed here by checking the banscore as part of
ProcessMessages() in addition to SendMessages().

When importing a watch-only address over importmulti with a specific timestamp,
the wallet's nTimeFirstKey is currently set to 1. After this change, the
provided timestamp will be used and stored as metadata associated with
watch-only key. This can improve wallet performance because it can avoid the
need to scan the entire blockchain for watch only addresses when timestamps are
provided.
Also adds timestamp to validateaddress return value (needed for tests).
Fixes#9034.
Additionally, accept a "now" timestamp, to allow avoiding rescans for keys
which are known never to have been used.
Note that the behavior when "now" is specified is slightly different than the
previous behavior when no timestamp was specified at all. Previously, when no
timestamp was specified, it would avoid rescanning during the importmulti call,
but set the key's nCreateTime value to 1, which would not prevent future block
reads in later ScanForWalletTransactions calls. With this change, passing a
"now" timestamp will set the key's nCreateTime to the current block time
instead of 1.
Fixes#9491
These are (afaik) all long-standing races or concurrent accesses. Going
forward, we can clean these up so that they're not all individual atomic
accesses.

- Make some vars atomic.

Minimum boost version was bumped to 1.47.0 in #8920, which
means the configure step won't even pass with older boost.
This version has boost filesystem v3, which means the
(crappy) fallbacks for older versions can go.
If a timeout happens while reading the proxy response, this effectively
means we timed out while connecting to the remote node. This is very
common for Tor, so do not print an error message.

Preserve comment, order form, and account strings from the original wallet
transaction. Also set fTimeReceivedIsTxTime and fFromMe fields for consistency
with CWallet::CreateTransaction. The latter two fields don't influence current
wallet behavior, but do record that the transaction originated in the wallet
instead of coming from the network or sendrawtransaction.
This silently skips trying to merge signatures from inputs which
do not exist from transactions provided to signrawtransaction,
instead of hitting an assert.
Since ForEach* are can be used to send messages to all nodes, the caller may
end up sending a message before the version handshake is complete. To limit
this, filter out these nodes. While we're at it, may as well filter out
disconnected nodes as well.
Delete unused methods rather than updating them.
This avoids having some vars set if the version negotiation fails.
Also copy it all into CNode at the same site. nVersion and
fSuccessfullyConnected are set last, as they are the gates for the other vars.
Make them atomic for that reason.
Once the CNode has been added to vNodes, it is possible that it is
disconnected+deleted in the socket handler thread. However, after
that we now call InitializeNode, which accesses the pnode.
helgrind managed to tickle this case (somehow), but I suspect it
requires in immensely braindead scheduler.
More accurate than simply adding one byte per input, and properly handles the
case where the original transaction happened to have very small signatures

5b15870 Use incrementalRelayFee for BIP 125 replacement (Alex Morcos)
The result value indicates the actual fee on the transaction that was replaced. But there is an error message which uses the description 'oldfee' to refer to the original fee rate applied to the new transaction's estimated max size. It was confusing that two different uses of 'oldfee' had two different numeric values.
Have wallet's default bump value be higher than the default incrementalRelayFee to future proof against changes to incremental relay fee. Only applies when not setting the fee rate directly.
Use the wallet's fee calculation logic to properly clamp fee against minimums and maximums when calculating the fee for a bumpfee transaction. Unless totalFee is explictly given, in which case, manually check against min, but do nothing to adjust given fee.
In all cases do a final check against maxTxFee (after adding any incremental amount).
Before this commit, the checkbox would always start off unchecked. After this
commit it will respect the -walletrbf setting (which is currently false by
default).
The use of mocktime in test logic means that comparisons between
GetTime() and GetTimeMicros()/1000000 are unreliable since the former
can use mocktime values while the latter always gets the system clock;
this changes the networking code's inactivity checks to consistently
use the system clock for inactivity comparisons.
Also remove some hacks from setmocktime() that are no longer needed,
now that we're using the system clock for nLastSend and nLastRecv.

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

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.

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 [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

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.

87c35f5 Remove orphan state wipe from UnloadBlockIndex. (Matt Corallo)
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.

this needs testing.
Also remove connection to non-existing slot "test".
This was used for testing if the signal arrived. It is no
longer necessary.

This creates a slight window for a race condition to happen, however this condition is harmless: it
will at most make us exit without printing a message to console.

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

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

Make ownership of the QThread object clear, so that the RPCConsole

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.

- Do sorting for date, amount and confirmations column as longlong, not

- 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.

GetTotalBlocksEstimate is no longer used and it was the only thing
the checkpoint tests were testing.
Since checkpoints are on their way out it makes more sense to remove
the test file than to cook up a new pointless test.
This introduces a 'minimum chain work' chainparam which is intended
to be the known amount of work in the chain for the network at the
time of software release. If you don't have this much work, you're
not yet caught up.
This is used instead of the count of blocks test from checkpoints.
This criteria is trivial to keep updated as there is no element of
subjectivity, trust, or position dependence to it. It is also a more
reliable metric of sync status than a block count.
Fixes newly initialized bloom filters being
constructed with isEmpty(false), which still
works but loses the possible speedup when
checking for key membership in an empty filter.
This will result in many more calls to CheckBlockIndex when
connecting a list of headers (eg in ::HEADERS messages processing)
but its only enabled in debug mode, and that should mostly just be
during IBD, so it should be OK.
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.
Additionally, the initialization of the recentRejects set is moved
to InitPeerLogic.
This splits the output comparison for `bitcoin-tx` into two steps:
- First, check for data mismatch, parsing the data as json or hex
depending on the extension of the output file
- Then, check if the literal string matches
For either of these cases give a different error.
This prevents wild goose chases when e.g. a trailing space doesn't match
exactly, and makes sure that both test output and examples are valid
data of the purported format.
Recent discussion (in IRC meetings, and e.g. #8989) has shown a
preference for the default confirm target for smartfees to be 6 instead
of 2, to avoid overpaying fees for questionable gain.
6 is also a compromise between the GUI's pre-#8989 value of 25 and the
bitcoind `-txconfirmtarget` default of 2. These were unified in #8989,
but this has made the (overly expensive) default of 2 as GUI default.
```
getmemoryinfo
Returns an object containing information about memory usage.
Result:
{
"locked": { (json object) Information about locked memory manager
"used": xxxxx, (numeric) Number of bytes used
"free": xxxxx, (numeric) Number of bytes available in current arenas
"total": xxxxxxx, (numeric) Total number of bytes managed
"locked": xxxxxx, (numeric) Amount of bytes that succeeded locking. If this number is smaller than total, locking pages failed at some point and key data could be swapped to disk.
}
}
Examples:
> bitcoin-cli getmemoryinfo
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getmemoryinfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/
```
Add a pool for locked memory chunks, replacing LockedPageManager.
This is something I've been wanting to do for a long time. The current
approach of locking objects where they happen to be on the stack or heap
in-place causes a lot of mlock/munlock system call overhead, slowing
down any handling of keys.
Also locked memory is a limited resource on many operating systems (and
using a lot of it bogs down the system), so the previous approach of
locking every page that may contain any key information (but also other
information) is wasteful.
This change is needed to prevent sync_blocks timeouts in the mempool_reorg
test after the sync_blocks update in the upcoming commit
"[qa] Change sync_blocks to pick smarter maxheight".
This change was initially suggested by Suhas Daftuar <sdaftuar@chaincode.com>
in https://github.com/bitcoin/bitcoin/pull/8680#r78209060
