Pull request description:
This is an alternative approach to #11534. Rather than disconnect an outbound peer when our tip looks stale, instead try to connect to an additional outbound peer.
Periodically, check to see if we have more outbound peers than we target (ie if any extra peers are in use), and if so, disconnect the one that least recently announced a new block (breaking ties by choosing the newest peer that we connected to).

720d9e8fa [Wallet] always show help-line of wallet encryption calls (Jonas Schnelli)
Pull request description:
We do currently show/hide the wallet encryption RPC calls from the help if the current wallet.
In case of an encrypted wallet, `encryptwallet` is hidden and `walletpassphrasechange`, `walletpassphrasechange` and `walletlock` do appear in the help.
This is no longer ideal in case of multiwallet due to the fact that one may want help infos in order to target a specific wallet.
IMO its preferable to have a static help screen (show everything always). The currently show/hidden calls do handle the possible invalid encryption-state fine.

If our tip hasn't updated in a while, that may be because our peers are
not relaying blocks to us that we would consider valid. Allow connection
to an additional outbound peer in that circumstance.
Also, periodically check to see if we are exceeding our target number of
outbound peers, and disconnect the one which has least recently
announced a new block to us (choosing the newest such peer in the case
of tie).

Pull request description:
@sdaftuar pointed out that the version in #11487 was somewhat DoS-able as someone could feed you a valid chain that forked off the the last checkpoint block and force you to do lots of work just walking backwards across blocks for each new block they gave you. We came up with a few proposals but settled on the one implemented here as likely the simplest without obvious DoS issues. It uses our existing on-load mapBlockIndex walk to make sure everything that descends from an invalid block is marked as such, and then simply caches blocks which we attempted to connect but which were found to be invalid. To avoid DoS issues during IBD, this will need to depend on #11458.
Includes tests from #11487.

b296bf1 Init: Remove redundant exit(EXIT_FAILURE) instances and replace with return false (donaloconnor)
Pull request description:
While reviewing the bitcoin code I noticed that there are a few exit(EXIT_FAILURE) at various places in the AppInit function.
This function returns to main() which will return/exit with EXIT_FAILURE so returning false instead of an explicit exit(EXIT_FAILURE) seems to be cleaner.
This PR attempts to make things a bit more consistent.
There is a subtle difference between exit() and return from main in that the exit() will not clean up any local vars but I don't think this makes a difference in this case. Using exit() might even lead to bugs in the future where the dtor of local objects are expected to be called.

This tracks the set of all known invalid-themselves blocks (ie
blocks which we attempted to connect but which were found to be
invalid). This is used to cheaply check if new headers build on an
invalid chain.
While we're at it we also resolve an edge-case in invalidateblock
on pruned nodes which results in them needing a reindex if they
fail to reorg.
This is a simple change that makes our accept requirements the
same as our request requirements, (ever so slightly) further
decoupling our consensus logic from our FindNextBlocksToDownload
logic in net_processing.
There is no reason to wish to store blocks on disk always just
because a peer is whitelisted. This appears to be a historical
quirk to avoid breaking things when the accept limits were added.
Nowhere else in the protocol do we send headers which are for
blocks we have not fully validated except in response to getheaders
messages with a null locator. On my public node I have not seen any
such request (whether for an invalid block or not) in at least two
years of debug.log output, indicating that this should have minimal
impact.
Reading the variable mapBlockIndex requires holding the mutex cs_main.
The new "Disconnect outbound peers relaying invalid headers" code
added in commit 37886d5e2f and merged
as part of #11568 two days ago did not lock cs_main prior to accessing
mapBlockIndex.

cc5c39d [Build] Add AM_OBJCXXFLAGS and QT_PIE_FLAGS to OBJCXXFLAGS to future-proof darwin targets (fanquake)
f8c6697 Fix automake warnings when running autogen.sh (Evan Klitzke)
Pull request description:
Adjusted @eklitzke's commit to completely remove GZIP_ENV.
Added a commit to address OBJCXXFLAGS.
Rebased on master.
Relevant info from @theuni & #11013 below.
--------
GZIP_ENV was indeed added for determinism, but gitian exports this as needed, so it's not really necessary. I'd rather just remove it.
The mm.o rule was added to support XCode 4.2's ancient version of automake. That's irrelevant now, so it makes sense to remove that too.
All darwin targets are PIE by default, so we don't technically need the flags, but I'd be more comfortable if we hooked up the OBJCXXFLAGS in case future ones are added.
--------
The second commit addresses the last point, but could probably use a better commit message.

37886d5e2 Disconnect outbound peers relaying invalid headers (Suhas Daftuar)
4637f1852 moveonly: factor out headers processing into separate function (Suhas Daftuar)
Pull request description:
Alternate to #11446.
Disconnect outbound (non-manual) peers that serve us block headers that are already known to be invalid, but exempt compact block announcements from such disconnects.
We restrict disconnection to outbound peers that are using up an outbound connection slot, because we rely on those peers to give us connectivity to the honest network (our inbound peers are not chosen by us and hence could all be from an attacker/sybil). Maintaining connectivity to peers that serve us invalid headers is sometimes desirable, eg after a soft-fork, to protect unupgraded software from being partitioned off the honest network, so we prefer to only disconnect when necessary.
Compact block announcements are exempted from this logic to comply with BIP 152, which explicitly permits nodes to relay compact blocks before fully validating them.

c60fd71 Disconnecting from bad outbound peers in IBD (Suhas Daftuar)
Pull request description:
The first commit will disconnect an outbound peer that serves us a headers chain with insufficient work while we're in IBD.
The second commit introduces a way to disconnect outbound peers whose chains fall out of sync with ours:
For a given outbound peer, we check whether their best known block (which is known from the blocks they announce to us) has at least as much work as our tip. If it doesn't, we set a 20 minute timeout, and if we still haven't heard about a block with as much work as our tip had when we set the timeout, then we send a single getheaders message, and wait 2 more minutes. If after two minutes their best known block has insufficient work, we disconnect that peer.
We protect 4 of our outbound peers (who provide some "good" headers chains, ie a chain with at least as much work as our tip at some point) from being subject to this logic, to prevent excessive network topology changes as a result of this algorithm, while still ensuring that we have a reasonable number of nodes not known to be on bogus chains.
We also don't require our peers to be on the same chain as us, to prevent accidental partitioning of the network in the event of a chain split. Note that if our peers are ever on a more work chain than our tip, then we will download and validate it, and then either reorg to it, or learn of a consensus incompatibility with that peer and disconnect. This PR is designed to protect against peers that are on a less work chain which we may never try to download and validate.
Tree-SHA512: 2e0169a1dd8a7fb95980573ac4a201924bffdd724c19afcab5efcef076fdbe1f2cec7dc5f5d7e0a6327216f56d3828884f73642e00c8534b56ec2bb4c854a656
Currently we have no rotation of outbound peers. If an outbound peer
stops serving us blocks, or is on a consensus-incompatible chain with
less work than our tip (but otherwise valid headers), then we will never
disconnect that peer, even though that peer is using one of our 8
outbound connection slots. Because we rely on our outbound peers to
find an honest node in order to reach consensus, allowing an
incompatible peer to occupy one of those slots is undesirable,
particularly if it is possible for all such slots to be occupied by such
peers.
Protect against this by always checking to see if a peer's best known
block has less work than our tip, and if so, set a 20 minute timeout --
if the peer is still not known to have caught up to a chain with as much
work as ours after 20 minutes, then send a single getheaders message,
wait 2 more minutes, and if a better header hasn't been received by then,
disconnect that peer.
Note:
- we do not require that our peer sync to the same tip as ours, just an
equal or greater work tip. (Doing otherwise would risk partitioning the
network in the event of a chain split, and is also unnecessary.)
- we pick 4 of our outbound peers and do not subject them to this logic,
to be more conservative. We don't wish to permit temporary network
issues (or an attacker) to excessively disrupt network topology.

low work, eg to fill up our disk. Since

threshold), but we would still process unrequested blocks that had more work
than our tip. This commit fixes that behavior.

Make sure wallet databases have unique fileids. If they don't, throw an error.
BDB caches do not work properly when more than one open database has the same
fileid, because values written to one database may show up in reads to other
databases.
Bitcoin will never create different databases with the same fileid, but users

258d33b41 [mempool] Mark unaccepted txs present in mempool as 'already there'. (Karl-Johan Alm)
Pull request description:
I was investigating the reasons for failed imports in mempool and noticed that `LoadMempool()` and `pwallet->postInitProcess()` (for all wallets) are executed concurrently. The wallet will end up importing transactions that `LoadMempool()` later tries to import; the latter will fail due to the tx already being in the mempool.
This PR changes the log message, adding an additional "already there" entry. For transactions not accepted into mempool, a check if they are in the mempool is done first, and if found, they are counted as 'already there', otherwise counted as 'failed'.
Also slight rewording for consistency (successes, failed, expired, ... -> succeeded, failed, expired).

Now using a std::unique_ptr, the Db instance is correctly released
when CDB initialization fails.
The internal CDB state and mapFileUseCount are only mutated when
the CDB initialization succeeds.
Note that UpdatedBlockTip is also used in net_processing to
announce new blocks to peers. As this may need additional review,
this change is included in its own commit.
This runs Block{Connected,Disconnected}, SetBestChain, Inventory,
and TransactionAddedToMempool on the background scheduler thread.
Of those, only BlockConnected is used outside of Wallet/ZMQ, and
is used only for orphan transaction removal in net_processing,
something which does not need to be synchronous with anything
else.
This partially reverts #9583, re-enabling some of the gains from
#7946. This does not, however, re-enable the gains achieved by
repeatedly releasing cs_main between each transaction processed.
This avoid calling out to mempool state during coin selection,
balance calculation, etc. In the next commit we ensure all wallet
callbacks from CValidationInterface happen in the same queue,
serialized with each other. This helps to avoid re-introducing one
of the issues described in #9584 [1] by further disconnecting
wallet from current chain/mempool state.
Thanks to @morcos for the suggestion to do this.
Note that there are several race conditions introduced here:
* If a user calls sendrawtransaction from RPC, adding a
transaction which is "trusted" (ie from them) and pays them
change, it may not be immediately used by coin selection until
the notification callbacks finish running. No such race is
introduced in normal transaction-sending RPCs as this case is
explicitly handled.
* Until Block{Connected,Disconnected} and
TransactionAddedToMempool calls also run in the CSceduler
background thread, there is a race where
TransactionAddedToMempool might be called after a
Block{Connected,Disconnected} call happens.
* Wallet will write a new best chain from the SetBestChain
callback prior to having processed the transaction from that
block.
[1] "you could go to select coins, need to use 0-conf change, but
such 0-conf change may have been included in a block who's
callbacks have not yet been processed - resulting in thinking they
are not in mempool and, thus, not selectable."
This prevents the wallet-RPCs-return-stale-info issue from being
re-introduced when new-block callbacks no longer happen in the
block-connection cs_main lock
This is both good practice (we want to move all such callbacks
into a background thread eventually) and prevents a lock inversion
when we go to use this in wallet (mempool.cs->cs_wallet and
cs_wallet->mempool.cs would otherwise both be used).
This is currently unused, but will by used by wallet to cache when
transactions are in the mempool, obviating the need for calls to
mempool from CWalletTx::InMempool()

Pull request description:
This was mostly written as a way to clean things up so that the NETWORK_LIMITED PR (#10387) can be simplified a ton, but its also a nice standalone cleanup that will also require a bit of review because it tweaks a lot of stuff across net. The new functions are fine in protocol.h right now since they're straight-forward, but after NETWORK_LIMITED will really want to move elsewhere after @theuni moves the nServices-based selection to addrman from connman.
Adds HasAllRelevantServices and GetRelevantServices, which check
for NETWORK|WITNESS.
This changes the following:
* Removes nRelevantServices from CConnman, disconnecting it a bit
more from protocol-level logic.
* Replaces our sometimes-connect-to-!WITNESS-nodes logic with
simply always requiring WITNESS|NETWORK for outbound non-feeler
connections (feelers still only require NETWORK).
* This has the added benefit of removing nServicesExpected from
CNode - instead letting net_processing's VERSION message
handling simply check HasAllRelevantServices.
* This implies we believe WITNESS nodes to continue to be a
significant majority of nodes on the network, but also because
we cannot sync properly from !WITNESS nodes, it is strange to
continue using our valuable outbound slots on them.
* In order to prevent this change from preventing connection to
-connect= nodes which have !WITNESS, -connect nodes are now
given the "addnode" flag. This also allows outbound connections
to !NODE_NETWORK nodes for -connect nodes (which was already true
of addnodes).
* Has the (somewhat unintended) consequence of changing one of the
eviction metrics from the same
sometimes-connect-to-!WITNESS-nodes metric to requiring
HasRelevantServices.
This should make NODE_NETWORK_LIMITED much simpler to implement.

~Locally, all the checkqueue tests ran 3.2X faster on my machine. The worst offender, `test_CheckQueue_Correct_Random` ran 3.4X faster.~
1. ~Removes `GetRand()` and replaces it with a single deterministic FastRandomContext instance.~ #10321 replicated this

d601f16 Fix invalid memory access in CScript::operator+= (Anthony Towns)
Pull request description:
This is a fix for #11114 -- invoking "s += s" gets turned into "s.insert(s.end(), s.begin(), s.end())" which can result in an invalid memory access is s.capacity() < 2*s.size() (because s gets resized and possibly moved, so s.begin() and s.end() become invalid references when reading the values to be appended).
The fix is straightforward: reserve enough space in advance, so that insert() doesn't need to resize and thus its arguments remain valid.
A simple test case is added as well; though you probably need to run it via valgrind to actually catch the problem when it's not fixed...

This fixes an issue where estimatesmartfee which matches at the min relay fee will return 999 sat/byte instead of 1000 sat/byte due to a float rounding issue. I went ahead and made all float <-> int conversion outside of test/qt explicit (test only had one or two more, Qt had quite a few, including many in the Qt headers themselves) and added overloads to CFeeRate to force callers to do an explicit round themselves. Easy to test with -Wfloat-conversion.

Second commit finally fixes the fact that we're not meant to reject based on mempool min fee when adding a transaction from a disconnected block during a reorg as mentioned [here](https://github.com/bitcoin/bitcoin/pull/9602#issue-202197849)

Pull request description:
Builds on top of #11117.
This adds support for:
* Creating BIP173 addresses for testing (through `addwitnessaddress`, though by default it still produces P2SH versions)
* Sending to BIP173 addresses (including non-v0 ones)
* Analysing BIP173 addresses (through `validateaddress`)
It includes a reformatted version of the [C++ Bech32 reference code](https://github.com/sipa/bech32/tree/master/ref/c%2B%2B) and an independent implementation of the address encoding/decoding logic (integrated with CTxDestination). All BIP173 test vectors are included.
Not included (and intended for other PRs):
* Full wallet support for SegWit (which would include automatically adding witness scripts to the wallet during automatic keypool topup, SegWit change outputs, ...) [see #11403]
* Splitting base58.cpp and tests/base58_tests.cpp up into base58-specific code, and "address encoding"-code [see #11372]
* Error locating in UI for BIP173 addresses.

In the SignatureHash function, the input index must refer to a valid
index. This is not enforced equally in the segwit/non-segwit branches
and should be an assertion rather than returning a error hash.
This adds the infrastructure `BaseRequestHandler` class that takes care
of converting bitcoin-cli arguments into a JSON-RPC request object, and
converting the reply into a JSON object that can be shown as result.
This is subsequently used to handle the `-getinfo` option, which sends
a JSON-RPC batch request to the RPC server with
`["getnetworkinfo", "getblockchaininfo", "getwalletinfo"]`,
and after reply combines the result into what looks like a `getinfo`
result.
There have been some requests for a client-side `getinfo` and this
is my PoC of how to do it. If this is considered a good idea
some of the logic could be moved up to rpcclient.cpp and
used in the GUI console as well.

Pull request description:
Deprecates estimatefee in v0.16, for final removal in v0.17.
This commit introduces a phased removal of RPC methods. RPC method is
disabled by default in version x, but can be enabled by using the
`-deprecatedrpc=<methodname>` argument. RPC method is removed entirely in version
(x+1).
This gives users fair warning that an RPC is to be removed, and time to change client software if necessary. Deprecation warnings in RPC return values or release notes are easily ignored.
This is a more generic version of the approach I tried to use in #10841, which too late to make it into v0.15.

df10edf More user-friendly error message when partially signing (MeshCollider)
Pull request description:
When partially signing a transaction using `signrawtransaction`, if the wallet doesn't have access to a key, it will output a scary error message `"error": "Operation not valid with the current stack size"`, yet it will partially sign the transaction anyway. This puts a lot of users off, because they don't realise the signing actually succeeded for some inputs. This catches that specific error when signing, and outputs a friendlier message which says `Unable to sign input, invalid stack size (possibly missing key)`.
This is the best way I could think of to fix the issue, but please let me know if you come up with a better way to do it :)

Pull request description:
Alternative to https://github.com/bitcoin/bitcoin/pull/11208, closes https://github.com/bitcoin/bitcoin/issues/11207
According to the [Qt documentation](https://doc.qt.io/qt-4.8/qwidget.html#restoreGeometry), restoreGeometry does all the checks we need, so it would be better to rely on them instead of doing it ourselves.
~Haven't tested this properly yet, hence the WIP.~
Gives expected behavior exactly as the other system apps do based on my tests. Only potential issue is the case when the GUI is almost entirely offscreen with only a single strip of pixels, its not really possible to see the GUI, but if you know it's there you can bring it back onscreen with just the mouse. And that's exactly how notepad behaves on Windows so I don't think its a real issue.
This also gives much better behavior when closing a maximized window, currently (0.15.0 release) a maximized window will save the window size on close, and then reopen as a not-maximized but still that size, which is really annoying. This reopens as maximized.

A C-style cast is equivalent to try casting in the following order:
1. const_cast(...)
2. static_cast(...)
3. const_cast(static_cast(...))
4. reinterpret_cast(...)
5. const_cast(reinterpret_cast(...))
By using static_cast<T>(...) explicitly we avoid the possibility
of an unintentional and dangerous reinterpret_cast. Furthermore
static_cast<T>(...) allows for easier grepping of casts.
In the case of CKey's destructor, it seems to have been an oversight in
f4d1fc259 not to delete it. At this point, it results in the move

This was added in order to help OpenNetworkConnection avoid creating a
connection that it would end up aborting. It was necessary because resolving
was done as part of the connection process.
Now that resolving is separated from connecting, this case is detected before
the connection is attempted.
ConnectSocketByName handled resolves as necessary, obscuring the connection
process. With them separated, each can be handled asynchronously.
Also, since proxies must be considered now anyway, go ahead and eliminate the
ConnectSocket wrapper and use ConnectSocketDirectly... directly.

std::unordered_map::erase( const_iterator pos ) returns an iterator to the element following the removed one. Use that to optimize (probably minor-performance-wise, and definitely code-structure-wise) the implementation of CCoinsViewCache::BatchWrite().
Use C++11's better capability of expressing an interface of a non-copyable class by publicly deleting its copy ctor and assignment operator instead of just declaring them private.

Make the non-const overload of CBlockIndex::GetAncestor() reuse the const overload implementation instead of the other way around. This way, the constness of the const overload implementation is guaranteed. The other way around, it was possible to implement the non-const overload in a way which mutates the object, and since that implementation would be called even for const objects (due to the reuse), we would get undefined behavior.

Pull request description:
`QButtonGroup->button()` may return a nullptr.
Accessing the object directly with `setChecked` seems fragile.
This is a simple fix to ensure to never call a button out of bounds (nullptr).
There are probably other places where a sanity check for `QSettings` are required.

Combine fLimitFree and fOverrideMempoolLimit into a single boolean:
bypass_limits. This is used to indicate that mempool limiting based on feerate
should be bypassed. It is used when readding transactions from a reorg and then
the mempool is trimmed to size after all transactions are added and they can be
evaluated in the context of their descendants. No changes to behavior.

This resolves an issue where estimatesmartfee would return 999
sat/byte instead of 1000, due to floating point loss of precision
Thanks to sipa for suggesting is_integral.
We were saving a div by caching the inverse as a float, but this
ended up requiring a int -> float -> int conversion, which takes
almost as much time as the difference between float mul and div.
There are lots of other more pressing issues with the bench
framework which probably require simply removing the adaptive
iteration count stuff anyway.
No sensible user will ever keep the default settings here, so not
having sensible defaults only serves to screw users who are
paying less attention, which makes for terrible defaults.
* This removes block-size-limiting code in favor of GBT clients
doing the limiting themselves (if at all).
* -blockmaxsize is deprecated and only used to calculate an implied
blockmaxweight, addressing confusion from multiple users.
* getmininginfo's currentblocksize return value was returning
garbage values, and has been removed, also removing a
GetSerializeSize call in some block generation inner loops and
potentially addressing some performance edge cases.

864cd2787 Move CBitcoinAddress to base58.cpp (Pieter Wuille)
5c8ff0d44 Introduce wrappers around CBitcoinAddress (Pieter Wuille)
Pull request description:
This patch removes the need for the intermediary Base58 type `CBitcoinAddress`, by providing {`Encode`,`Decode`,`IsValid`}`Destination` functions that directly operate on the conversion between `std::string`s and `CTxDestination`.
As a side, it also fixes a number of indentation issues, and removes probably several unnecessary implicit `CTxDestination`<->`CBitcoinAddress` conversions.
This change is far from complete. In follow-ups I'd like to:
* Split off the specific address and key encoding logic from base58.h, and move it to a address.h or so.
* Replace `CTxDestination` with a non-`boost::variant` version (which can be more efficient as `boost::variant` allocates everything on the heap, and remove the need for `boost::get<...>` and `IsValidDestination` calls everywhere).
* Do the same for `CBitcoinSecret`, `CBitcoinExtKey`, and `CBitcoinExtPubKey`.
However, I've tried to keep this patch to be minimally invasive, but still enough to support non-Base58 addresses. Perhaps a smaller patch is possible to hack Bech32 support into `CBitcoinAddress`, but I would consider that a move in the wrong direction.

1. The RPC help text should use the constant `CURRENCY_UNIT` defined in `policy/feerate.cpp` instead of the literal `'BTC'`.
In the following 2 RPC commands, `'BTC'` is written directly in the help text.
This commit changes them to use that constant.
1) `estimatesmartfee`
2) `estimaterawfee`
2. Some RPC command use `'satoshis'` as the unit.
It should be written as `'satoshis'` instead of `'Satoshis'` in the RPC help text.
So, this commit fixes this typo in `getblocktemplate`.

I can understand wanting a general util file for tests to use, but if there's nothing in it, we might as well remove it, it can always be added back later when it's put to use.

1. The RPC help text should use the constant CURRENCY_UNIT defined in
policy/feerate.cpp instead of the literal 'BTC'. In the following
2 RPC commands, 'BTC' is written directly in the help text.
1) estimatesmartfee
2) estimaterawfee
And also, for these help strings, the notation
'fee-per-kilobyte (in BTC)' is somewhat ambiguous.
To write more precisely, this commit changes to 'fee rate in BTC/kB'
with using the constant CURRENCY_UNIT.
2. Some RPC command use 'satoshis' as the unit. It should be written
as 'satoshis' instead of 'Satoshis' in the RPC help text.
So, this commit fixes this typo in getblocktemplate.
3. The phrase that '... feerate (BTC per KB) ...' is used to explain
the fee rate in the help text of following 2 RPC commands.
1) getmempoolinfo
2) fundrawtransaction
But they are different from other similar help text of the RPCs.
And also, 'KB' implies Kibibyte (2^10 byte).
To unify and to clarify, this commit changes these phrase to
'... fee rate in BTC/kB ...'.
(BTC references the constant 'CURRENCY_UNIT')

On startup, the wallets will start pumping wallet transactions into the mempool in a different thread while LoadMempool() is running.
This will sometimes result in transactions "failing" to be accepted into mempool, but only for the reason that they were already
put there by a wallet. The log message for mempool load would note this as a 'failure' to import, which was misleading; it should
instead mark it as the transaction already being in the mempool.
Replace witness-stripped wallet transactions with full transactions;
this can happen when upgrading from a pre-segwit wallet to a segwit-
aware wallet.
All the other files in the repo which include bitcoin-config.h do so with the appropriate subfolder prefixed: config/bitcoin-config.h
The header should be included with the appropriate subfolder here as well.
This canonicalization also allows getting rid of a bit of extra configuration in Makefile.am.

de9a1db Acquire cs_main lock before cs_wallet during wallet initialization (Russell Yanofsky)
Pull request description:
`CWallet::MarkConflicted` may acquire the `cs_main` lock after `CWalletDB::LoadWallet` acquires the `cs_wallet` lock during wallet initialization. (`CWalletDB::LoadWallet` calls `ReadKeyValue` which calls `CWallet::LoadToWallet` which calls `CWallet::MarkConflicted`). This is the opposite order that `cs_main` and `cs_wallet` locks are acquired in the rest of the code, and so leads to `POTENTIAL DEADLOCK DETECTED` errors if bitcoin is built with `-DDEBUG_LOCKORDER`.
This commit changes `CWallet::LoadWallet` (which calls `CWalletDB::LoadWallet`) to acquire both locks in the standard order.

a54c7b9 Fix rounding errors in calculation of minimum change size (Alex Morcos)
Pull request description:
Thanks to @juscamarena for reporting this.
Please backport to 0.15.
There was a potential rounding error where the fee for the change added to the fee for the original tx could be less than the fee for the tx including change.
This is fixed in the first commit. The second commit adds one more snippet of information in the fee calculation report. I actually realized that there is more information that would be nice to report, but we can add that post 0.15.
An open question is whether we should be returning failure if the test in line 2885 is hit or just resetting pick_new_inputs and continuing. Originally I made it a failure to avoid any possible infinite loops. But the case hit here is an example of where that logic possibly backfired.

d97fe20 Move some static functions out of wallet.h/cpp (Russell Yanofsky)
Pull request description:
This just moves some static wallet fee and init functions out of `wallet/wallet.cpp` and into new `wallet/fees.cpp` and `wallet/init.cpp` source files. There is one commit updating declarations and callers, followed by two MOVEONLY commits actually moving the function bodies.
This change is desirable because wallet.h/cpp are monolithic and hard to navigate, so pulling things out and grouping together pieces of related functionality should improve the organization.
Another motivation is the wallet process separation work in https://github.com/bitcoin/bitcoin/pull/10973, where (at least initially) parameter parsing and fee estimation are still done in the main process rather than the wallet process, and having functions that run in different processes scrambled up throughout wallet.cpp is unnecessarily confusing.

1. Calculate nblocks more adaptive.
If not specify nblocks-parameter, illegal parameter error
will happen when target block height is below blocks for 1 month.
To avoid this error, set default nblocks to
min(blocks for 1 month, target block's height - 1)
And allowing 0 so that this RPC works good even if target block is
genesis block or 1st block.
2. Correct error message.
nblocks accepts [0 .. block's height -1] . so fix as following:
"Invalid block count: should be between 0 and the block's height - 1"
3. Add check 0-divide.
If nTimeDiff = 0 then returns {... "txrate":} and
bitcoin-cli cannot handle the response.
To avoid this error, do not return "txrate" if nTimeDiff = 0.
4. Add following 3 elements to the return object.
1) 'window_block_count' : Size of the window in number of blocks.
2) 'window_tx_count' : The number of transactions in the window.
3) 'window_interval' : The elapsed time in the window.

Add attribute `[[noreturn]]` (C++11) to functions that will not return.
Rationale:
* Reduce the number of false positives/false negatives from static analyzers with regards to things such as unused or unreachable code
* Potentially enable additional compiler optimizations

e067673 Avoid treating null RPC arguments different from missing arguments (Russell Yanofsky)
e666efc Get rid of redundant RPC params.size() checks (Russell Yanofsky)
Pull request description:
This is a followup to #10783.
- The first commit doesn't change behavior at all, just simplifies code.
- The second commit just changes RPC methods to treat null arguments the same as missing arguments instead of throwing type errors.
- The third commit updates developer notes after the cleanup.
- The forth commit does some additional code cleanup in `getbalance`.
Followup changes that should happen in future PRs:
- [ ] Replace uses of `.isTrue()` with calls to `.get_bool()` so numbers, objects, and strings cause type errors instead of being interpreted as false. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133850525
- [ ] Add braces around if statements. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133851133
- [ ] Maybe improve UniValue type error exceptions and eliminate RPCTypeCheck and RPCTypeCheckArgument functions. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133829303

4aa2508 Bugfix: Use testnet RequireStandard for -acceptnonstdtxn default (Luke Dashjr)
Pull request description:
Fixes a bug introduced in #8855
`-acceptnonstdtxn` is a valid option only for testnet/regtest (in Core), and the help message reflects that. Currently, however, it is buggy in two ways:
1. It uses mainnet to get the default value, which doesn't make sense since the option is never available for mainnet, and the only time the option is available, is when the default is the opposite.
2. It uses the value of "require standard" directly as the default for "accept non-standard transactions", but these concepts are opposites: a negation must be performed to transform one to the other.
Note the combination of these bugs results in the correct boolean output, but the logic to get there is completely wrong.

e53615b Remove vchDefaultKey and have better first run detection (Andrew Chow)
Pull request description:
Removes vchDefaultKey which was only used for first run detection. Improves wallet first run detection by checking to see if any keys were read from the database.
This also fixes a (rather contrived) case where an encrypted non-HD wallet has corruption such that the default key is no longer valid and is loaded into a Core version that supports HD wallets. This causes a runtime exception since a new hd master key is generated as the software believes the wallet file is newly created but cannot add the generated key to the wallet since it is encrypted. I was only able to replicate this error by creating a non-hd wallet, encrypting it, then editing the wallet using `db_dump` and `db_load` before loading the wallet with hd enabled. This problem has been reported by [two](https://bitcointalk.org/index.php?topic=1993244.0) [users](https://bitcointalk.org/index.php?topic=1746976.msg17511261#msg17511261) so it is something that can happen, although that raises the question of "what corrupted the default key".

Removes vchDefaultKey which was only used for first run detection.
Improves wallet first run detection by checking to see if any keys
were read from the database.
This will now also check for a valid defaultkey for backwards
compatibility reasons and to check for any corruption.
Keys will stil be generated on the first one, but there won't be
any shown in the address book as was previously done.
Only change in behavior is that unsupported combinations of parameters now
trigger more specific error messages instead of the vague "JSON value is not a
string as expected" error.

This changes RPC methods to treat null arguments the same as missing arguments,
instead of throwing type errors. Specifically:
- `getbalance` method now returns the wallet balance when the `account` param
is null instead of throwing a type error (same as when parameter is missing).
It is still an error to supply `minconf` or `watchonly` options when the
account is null.
- `addnode` and `setban` methods now return help text instead of type errors if
`command` params are null (same as when params are missing).
- `sendrawtransaction`, `setaccount`, `movecmd`, `sendfrom`,
`addmultisigaddress`, `listaccounts`, `lockunspent` methods accept null
default values where missing values were previously allowed, and treat them
the same.
This commit just moves a few function declarations and updates callers.
Function bodies are moved in two followup MOVEONLY commits.
This change is desirable because wallet.h/cpp are monolithic and hard to
navigate, so pulling things out and grouping together pieces of related
functionality should improve the organization.
Another proximate motivation is the wallet process separation work in
https://github.com/bitcoin/bitcoin/pull/10973, where (at least initially)
parameter parsing and fee estimation are still done in the main process rather
than the wallet process, and having functions that run in different processes
scrambled up throughout wallet.cpp is unnecessarily confusing.
90d4d89 scripted-diff: Use the C++11 keyword nullptr to denote the pointer literal instead of the macro NULL (practicalswift)
Pull request description:
Since C++11 the macro `NULL` may be:
* an integer literal with value zero, or
* a prvalue of type `std::nullptr_t`
By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.
For a more thorough discussion, see "A name for the null pointer: nullptr" (Sutter &
Stroustrup), http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf
With this patch applied there are no `NULL` macro usages left in the repo:
```
$ git grep NULL -- "*.cpp" "*.h" | egrep -v '(/univalue/|/secp256k1/|/leveldb/|_NULL|NULLDUMMY|torcontrol.*NULL|NULL cert)' | wc -l
0
```
The road towards `nullptr` (C++11) is split into two PRs:
* `NULL` → `nullptr` is handled in PR #10483 (scripted, this PR)
* `0` → `nullptr` is handled in PR #10645 (manual)

This PR contains the first part of #10882 :
- if a key from the keypool is used, mark all keys up to that key as used, and then try to top up the keypool
- top up the keypool on startup
Notably, it does not stop the node or prevent the best block from advancing if the keypool drops below a threshold (which means that transactions may be missed and funds lost if restoring from an old HD wallet backup).

With this, the amounts returned in `decoderawtransaction` will be padded to 8 digits like anywhere else in the API.
This is accomplished by using `ValueFromAmount` in `TxToUniv`, instead of `FormatMoney` which it currently (mistakingly) uses. The `FormatMoney` function is only for debugging/logging use!
To avoid dependency issues, `ValueFromAmount` is moved to `core_write.cpp`, where it also fits better. I don't move `AmountFromValue` to `core_read.cpp` at the same time, as this would have more impact due to the RPCError dependency there.
(n.b.: large number of changed files is solely due to the util_tests JSONs needing update)

This is necessary because core_write has to write amounts in
TxToUniv, and mistakingly uses FormatMoney for that
(which is only for debugging).
We don't move AmountFromValue at the same time, as
this is more challenging due to the RPCError depencency
there.

Pull request description:
Immediately disconnect peers that use service bits 6 and 8 until August 1st, 2018
These bits have been used as a flag to indicate that a node is running incompatible
consensus rules instead of changing the network magic, so we're stuck disconnecting
based on the service bits, at least for a while.
Staying connected to nodes on other networks only prevents both sides from reaching consensus quickly, wastes network resources on both sides, etc.
Didn't add constants to protocol.h as the code there notes that "service bits should be allocated via the BIP process".

This fixes a few cases where we should be treating a restart-after-
coinsviewdb-reset identically to a just-reset-coinsviewdb.
Thanks to @morcos for identifying the bug.
This more clearly uses fReindex vs fReset to make sure we're not
clearing our coinsdb needlessly when restarting after a reindex.
It also makes it so that restarting after shutting down mid-reindex
isn't treates specially at all during txdb loading code, as it
shouldn't be.
This resolves a possible-assert-on-shutdown race introduced in
1f668b6468 when early shutdown
occurs.
Previously this was not done to avoid any cases where the
threadGroup might not exit due to a blocking thread, but at this
point the threadGroup isn't used all that much, plus Qt already
does this, and its good to keep their init/shutdown consistent.
For those curious, the threadGroup is only used in a few places:
* Its used to run the CCheckQueues in script validation, but these
use the boost mutex/condition variable primitives, so they
respect the interrupt pretty trivially.
* Its used for the import thread, which should exit rather quickly
as mostly it just calls LoadExternalBlockFile, which has an
interruption_point right before each block loaded.
* Its used in the scheduler thread, which is only used for:
* validationinterface has an effectively-dummy reference to it.
* wallet compaction, which should not last long
* addr/banlist dumping from CConnman, which should also be fast

This is to fix cases where we don't have all of the private keys (for something like a multisig address) but have the redeemscript so we can witnessify it.

efeb273 Force on-the-fly compaction during pertxout upgrade (Pieter Wuille)
Pull request description:
It seems that LevelDB tends to leave the old "per txid" UTXO entries in the database lying around for a significant amount of time during and after the per-txout upgrade. This introduces a `CompactRange` function in the database wrapper, and invokes it after every batch of updates in `CCoinsViewDB::Upgrade()`. This lowers temporary disk usage during and after the upgrade.

eda888e Fix some LoadChainTip-related init-order bugs. (Matt Corallo)
Pull request description:
This does a number of things to clean up chainstate init order,
fixing some issues as it goes:
* Order chainstate init more logically - first all of the
blocktree-related loading, then coinsdb, then
pcoinsTip/chainActive. Only create objects as needed.
* More clearly document exactly what is and isn't called in
-reindex and -reindex-chainstate both with comments noting
calls as no-ops and by adding if guards.
* Move the writing of fTxIndex to LoadBlockIndex - this fixes a
bug introduced in d6af06d68a where
InitBlockIndex was writing to fTxIndex which had not yet been
checked (because LoadChainTip hadn't yet initialized the
chainActive, which would otherwise have resulted in
InitBlockIndex being a NOP), allowing you to modify -txindex
without reindex, potentially corrupting your chainstate!
* Rename InitBlockIndex to LoadGenesisBlock, which is now a more
natural name for it. Also check mapBlockIndex instead of
chainActive, fixing a bug where we'd write the genesis block out
on every start.
* Move LoadGenesisBlock further down in init. This is a more logical
location for it, as it is after all of the blockindex-related
loading and checking, but before any of the UTXO-related loading
and checking.
* Give LoadChainTip a return value - allowing it to indicate that
the UTXO DB ran ahead of the block DB. This just provides a nicer
error message instead of the previous mysterious
assert(!setBlockIndexCandidates.empty()) error.
* Calls ActivateBestChain in case we just loaded the genesis
block in LoadChainTip, avoiding relying on the ActivateBestChain
in ThreadImport before continuing init process.
* Move all of the VerifyDB()-related stuff into a -reindex +
-reindex-chainstate if guard. It couldn't do anything useful
as chainActive.Tip() would be null at this point anyway.

Instead of using ismine to check whether an address can be spent by us,
make the witness version of the script or address first and then use
ProduceSignature with the DummySignatureCreator to check if we can
solve for the script.
Also fixes test cases to reflect this change.
* Order chainstate init more logically - first all of the
blocktree-related loading, then coinsdb, then
pcoinsTip/chainActive. Only create objects as needed.
* More clearly document exactly what is and isn't called in
-reindex and -reindex-chainstate both with comments noting

* Move LoadGenesisBlock further down in init. This is a more logical
location for it, as it is after all of the blockindex-related

and checking.
* Move all of the VerifyDB()-related stuff into a -reindex +
-reindex-chainstate if guard. It couldn't do anything useful
as chainActive.Tip() would be null at this point anyway.
RewindBlockIndex works over both chainActive - disconnecting blocks
from the tip that need witness verification - and mapBlockIndex -
requiring redownload of blocks missing witness data.
It should never have been the case that the second half is skipped
if we're about to run -reindex-chainstate.
This gives LoadChainTip a return value - allowing it to indicate that
the UTXO DB ran ahead of the block DB. This just provides a nicer
error message instead of the previous mysterious
assert(!setBlockIndexCandidates.empty()) error.
This also calls ActivateBestChain in case we just loaded the genesis
block in LoadChainTip, avoiding relying on the ActivateBestChain
in ThreadImport before continuing init process.
* Move the writing of fTxIndex to LoadBlockIndex - this fixes a
bug introduced in d6af06d68a where
InitBlockIndex was writing to fTxIndex which had not yet been

`setenv` function is not available from the Microsoft runtime library. Need to use `_putenv_s` instead.
This solution tells the compiler to use `_putenv_s` on `WIN32` compilation (Note: this also works on 64-bit Windows instances.) and `setenv` everywhere else.
I've tested builds on Windows 10 x64 and Ubuntu 16.04 with this code.

9737572 [Qt] Use wallet 0 in rpc console if running with multiple wallets (Jonas Schnelli)
Pull request description:
Current master with multiwallet results in accessing wallet 0 in QT (send / receive / tx history / etc.), **but** the RPC console cannot access that wallet (only non-wallet commands work).
This is a quick solution to re-allow accessing the same wallet (Index 0) via RPC console in multiwallet.
The solutions design is not "state of the art" (should go over WalletModel). Ideally we work on an overall multiwallet support for the GUI (which then would remove this change).
I think we should consider this as a bugfix.

Rationale:
Readability, SetSocketNonBlocking does what it says on the tin.
Consistency, More consistent with the rest of the API in this unit.
Reusability, SetSocketNonBlocking can also be used by clients that may not want to close the socket on failure.
This also moves the responsibility of closing the socket back to the caller that opened it, which in general should know better how and when to close it.

f999c46 listsinceblock: optionally find and list any transactions that were undone due to reorg when requesting a non-main chain block in a new 'removed' array. (Karl-Johan Alm)
Pull request description:
The following scenario will not notify the caller of the fact `tx0` has been dropped:
1. User 1 receives BTC in tx0 from utxo1 in block aa1.
2. User 2 receives BTC in tx1 from utxo1 (same) in block bb1
3. User 1 sees 2 confirmations at block aa3.
4. Reorg into bb chain.
5. User 1 asks `listsinceblock aa3` and does not see that tx0 is now invalidated.
See `listsinceblock.py` commit for related test.
The proposed fix is to iterate from the given block down to the fork point, and to check each transaction in the blocks against the wallet, in addition to including all transactions from the fork point to the active chain tip (the current behavior). Any transactions that were present will now also be listed in the `listsinceblock` output in a new `replaced` array. This operation may be a bit heavy but the circumstances (and perceived frequency of occurrence) warrant it, I believe.

Pull request description:
This adds an SSE4 assembly version of the SHA256 transform by Intel, and uses it at run time if SSE4 instructions are available, and use a fallback C++ implementation otherwise. Nearly every x86_64 CPU supports SSE4. The feature is only enabled when compiled with `--enable-experimental-asm`.
In order to avoid build dependencies and other complications, the original Intel YASM code was translated to GCC extended asm syntax.
This gives around a 50% speedup on the SHA256 benchmark for me.
It is based on an earlier patch by @laanwj, though only includes a single assembly version (for now), and removes the YASM dependency.

These lines confuse me.
Correct me if I am wrong, but we can't check any more blocks than we have right?
If someone requests <= 0 it get set it into some huge number and then immediately limit it to the chain height in the following statement.
````
if (nCheckDepth > chainActive.Height())
nCheckDepth = chainActive.Height();
````
when using ````--checkblocks=Z```` When Z is ````0```` or any other negative number, it will check all blocks.
I think it should be changed to this maybe.
````
if (nCheckDepth <= 0 || nCheckDepth > chainActive.Height())
nCheckDepth = chainActive.Height();
````
Which gets rid of that huge number which is confusing for any other altcoins that have a different block time.

Previously for these parameters, it was fine to omit them as positional arguments, but it would trigger UniValue runtime errors to set them to null, or to omit them while passing named parameters with greater positions (which would internally set earlier missing arguments to null). Now null values are treated the same as missing values so these errors do not occur.

f4d00e6 Add a discard_rate (Alex Morcos)
b138585 Remove factor of 3 from definition of dust. (Alex Morcos)
Pull request description:
The definition of dust is redefined to remove the factor of 3.
Dust is redefined to be the value of an output such that it would
cost that value in fees to (create and) spend the output at the dust
relay rate. The previous definition was that it would cost 1/3 of the
value. The default dust relay rate is correspondingly increased to
3000 sat/kB so the actual default dust output value of 546 satoshis
for a non-segwit output remains unchanged. This commit is a refactor
only unless a dustrelayfee is passed on the commandline in which case
that number now needs to be increased by a factor of 3 to get the same
behavior. -dustrelayfee is a hidden command line option.
Note: It's not exactly a refactor due to edge case changes in rounding
as evidenced by the required change to the unit test.
A discard_rate is added which defaults to 10,000 sat/kB

cf82a9e Do not allow users to get keys from keypool without reserving them (Matt Corallo)
Pull request description:
fundrawtransaction allows users to add a change output and then
not have it removed from keypool. While it would be nice to have

misunderstand or misuse this option.
This partially reverts #9377. Would be nice to get this for 15 since its kinda crazy we have this option to begin with IMO, will need release notes as an RPC option is now ignored.

This could be particularly nasty in some use-cases (especially
pre-HD-split) - eg a user might fundrawtransaction, then call
getnewaddress, hand out the address for someone to pay them, then
sendrawtransaction. This may result in the user thinking they have
received payment, even though it was really just their own change!
This could obviously result in needless key-reuse.

Pull request description:
This carries the walletdb object from top-up through GenerateNewKey/DeriveNewChildKey/CWallet::AddKeyPubKey, which allows us to avoid the flush on destruction until the top up finishes instead of flushing the wallet for every key.
This speeds up adding keys by well over 10x on my laptop (actually something like 17x), I wouldn't be surprised if it were an even bigger speedup on spinning rust.
Then it increases the keypool size to 1000. I would have preferred to use 10,000 but in the case where the user creates a new wallet and then turns on encryption it seems kind of dumb to have >400KB of marked-used born unencrypted keys just laying around.

This redefines dust to be the value of an output such that it would
cost that value in fees to (create and) spend the output at the dust
relay rate. The previous definition was that it would cost 1/3 of the
value. The default dust relay rate is correspondingly increased to
3000 sat/kB so the actual default dust output value of 546 satoshis
for a non-segwit output remains unchanged. This commit is a refactor
only unless a dustrelayfee is passed on the commandline in which case
that number now needs to be increased by a factor of 3 to get the same
behavior. -dustrelayfee is a hidden command line option.
Note: It's not exactly a refactor due to edge case changes in rounding
as evidenced by the required change to the unit test.

Pull request description:
This builds on #10589 (first 5 commits from that PR, last 5 commits are new)
The first couple commits refactor to use the CCoinControl class to pass fee calculation parameters around.
This allows for fixing the buggy interaction in QT between the global payTxFee which can be modified by the RPC call settxfee or temporarily modified by the QT custom fee settings. Before these changes the GUI could sometimes send a transaction with a recently set payTxFee and not respect the settings displayed in the GUI. After these changes, using the GUI does not involve the global transaction confirm target or payTxFee.
The prospective fee displays in the smart fee slider and the coin control dialog are changed to use the fee calculation from GetMinimumFee, this simplifies the code and makes them slightly more correct in edge cases.
Maxing the fee calculation with the mempool min fee is move from estimateSmartFee to GetMinimumFee.
This fixes a long standing bug, and should be tagged for 0.15 as it is holding up finalizing the estimatesmartfee RPC API before release.

Pull request description:

zapwallettxes would cause wallet transactions to be zapped, but they
would then be reloaded from the mempool on startup. This commit softsets
persistmempool to false if zapwallettxes is enabled so transactions are
actually zapped.
This PR also fixes the zapwallettxes.py functional test, which did not properly test this feature. The test line:
```py
assert_raises(JSONRPCException, self.nodes[0].gettransaction, [txid3])
#there must be a expection because the unconfirmed wallettx0 must be gone by now
```
is not actually testing the presence of the transaction since the RPC is being called incorrectly (with an array instead of a string). The `assert_raises()` passes since an assert is raised, but it's not the one the test writer had in mind!
Fixes#9710 .

should now be equivalent to
`bitcoin-cli -rpcconnect=::1 <command>`

This check has been moved to the wallet logic GetMinimumFee. The rpc call to
estimatesmartfee will now no longer return a result maxed with the mempool min
fee, but automated fee calculations from the wallet will produce the same result
as before and coincontrol and sendcoins dialogs in the GUI will correctly
display the right prospective fee.
changes to policy/fees.cpp include a big whitespace indentation change.
Remove helper function (CalculateEstimateType) for determining whether
estimates should be conservative or not, now that this is only called
once from GetMinimumFee and incorporate the logic directly there.
This fixes buggy behavior where we were temporarily setting and unsetting the
global payTxFee when trying to send a transaction with a custom fee from the
GUI. The previous behavior was inconsistent depending on the order of using the
RPC call settxfee and clicking various radio buttons in the sendcoinsdialog.
The new behavior is that transactions sent with the GUI will always use either
the smartfee slider value or the custom fee set on the GUI and they will not
affect the global defaults which are only for RPC and initial GUI values.

Some people keep thinking that MAX_BLOCK_BASE_SIZE is a separate
size limit from the weight limit when it fact it is superfluous,
and used in early tests before the witness data has been
validated or just to compute worst case sizes. The size checks
that use it would not behave any differently consensus wise
if they were eliminated completely.
Its correct value is not independently settable but is a function
of the weight limit and weight formula.
This patch just eliminates it and uses the scale factor as
required to compute the worse case constants.
It also moves the weight factor out of primitives into consensus,
which is a more logical place for it.

Adding comment to assert in PartialMerkleTree::CalcHash()
Adding comment on CMerkleBlock indicating it calls something that contains an assert
Removing EOL whitespace
Due to the iterative process of selecting new coins in each loop a new fee is
calculated that needs to be met each time. In the typical case if the most
recent iteration of the loop produced a much smaller transaction and we have now
gathered inputs with too many fees, we can just reduce the change. However in
the case where there is no change output, it is possible to end up with a
transaction which drastically overpays fees. This commit addresses that case,
by creating a change output if the overpayment is large enough to support it,
this is accomplished by rerunning the transaction creation loop without
selecting new coins.
Thanks to instagibbs for working on this as well

That OP_NOP10 is the last executable opcode is a bit of a obscure trivia, and the MAX_OPCODE constant already exists. This merely standardizes use of MAX_OPCODE over OP_NOP10 where it makes sense and is more clear.

Add support for setting each of these attributes on a per RPC call basis to sendtoaddress, sendmany, fundrawtransaction (already had RBF), and bumpfee (already had RBF and conf target).
Note that the CScheduler thread cant be running at this point,
it has already been stopped with the rest of the init threadgroup.
Thus, just calling any remaining loose callbacks during Shutdown()
is sane.
This will be used by CValidationInterface soon.
This requires a bit of work as we need to ensure that most of our
callbacks happen in-order (to avoid synchronization issues in
wallet) - we keep our own internal queue and push things onto it,
scheduling a queue-draining function immediately upon new
callbacks.

Use __func__ macro in std::runtime_exception to:
1. fix method name in CWalletTx::GetAvailableWatchOnlyCredit()
2. refactor CWalletTx::GetAvailableCredit()
(by hiding boost::signals stuff in the .cpp)
This allows us to give it a bit more intelligence as we move
forward, including routing some signals through CScheduler. While
the introduction of a "internals" pointer in the class is pretty
ugly, the fact that we no longer need to include boost/signals
directly from validationinterface.h is very much worth the loss.

This makes it possible to mine to any wallet when multi-wallet mode is added.
Solves the same problem as #10649, but IMO in a cleaner way.
It also gets rid of the circuitous `ScriptForMining` method on
`CValidationInterface`, which really doesn't belong there.
After this change it's still possible to mine without wallet through
`generatetoaddress`.

Check that cached script execution results are only valid for the same
script flags; that script execution checks are returned for non-cached
transactions; and that cached results are only valid for transactions
with the same witness hash.
Checking for the existence in the CCoinsViewCache of the outputs of a new tx
will result in a disk hit for every output since they will not be found. On the
other hand if those outputs exist already, then the inputs must also have been
missing, so we can move this check inside the input existence check so in the
common case of a new tx it doesn't need to run.
The purpose of the check is to avoid spamming the orphanMap with slightly old
txs which we have already seen in a block, but it is already only optimistic
(depending on the outputs not being spent), so make it even more efficient by
only checking the cache and not the entire pcoinsTip.
c074752 [RPC] Add an uptime command that displays the amount of time that bitcoind has been running (Ricardo Velhote)

This removes the possibility for GetCoin/HaveCoin/HaveCoinInCache to return
true while the respective coin is spent. By doing it across all calls, some
extra checks can be eliminated.
coins_tests is modified to call HaveCoin sometimes before and sometimes
after AccessCoin. A further change is needed because the semantics for
GetCoin slightly changed, causing a pruned entry in the parent cache to not
be pulled into the child in FetchCoin.
Adds new functional test, dbcrash.py, which uses -dbcrashratio to exercise the
logic for recovering from a crash during chainstate flush.
dbcrash.py is added to the extended tests, as it may take ~10 minutes to run
Use _Exit() instead of exit() for crash simulation
This eliminates stderr output such as:
terminate called without an active exception
or
Assertion failed: (!pthread_mutex_destroy(&m)), function ~recursive_mutex, file /usr/local/include/boost/thread/pthread/recursive_mutex.hpp, line 104.
Eliminating the stderr output on crash simulation allows testing with
test_runner.py, which reports a test as failed if stderr is produced.
This requires that we not access pcoinsTip in InitBlockIndex's
FlushStateToDisk (so we just skip it until later in AppInitMain)
and the LoadChainTip in LoadBlockIndex (which there is already one
later in AppinitMain, after ReplayBlocks, so skipping it there is
fine).
Includes some simplifications by Suhas Daftuar and Pieter Wuille.

In order to prevent mixups, our internal range is never allowed as a resolve
result. This means that no user-provided string will ever be confused with an
internal address.
We currently do two resolves for dns seeds: one for the results, and one to
serve in addrman as the source for those addresses.
There's no requirement that the source hostname resolves to the stored
identifier, only that the mapping is unique. So rather than incurring the
second lookup, combine a private subnet with a hash of the hostname.
The resulting v6 ip is guaranteed not to be publicy routable, and has only a
negligible chance of colliding with a user's internal network (which would be
of no consequence anyway).
Since cfe77ef41 the global nTxConfirmTarget wasn't being updated by the smart
fee slider and thus the coin control dialog and labels were not being updated.

In Olaoluwa Osuntokun's recent protocol proposal they were using a
mod in an inner loop. I wanted to suggest a normative protocol
change to use the trick we use here, but to find an explanation
of it I had to dig up the PR on github. After I posted about it
several other developers commented that it was very interesting
and they were unaware of it.
I think ideally the code should be self documenting and help
educate other contributors about non-obvious techniques that
we use. So I've written a description of the technique with
citations for future reference.

While the current implementation is pretty free, there is a lot
of possibility for this to blow up in our face with future changes,
especially as the backing map gets tweaked.
There are some similar asserts which are left removed in policy

Previously it was possible for HaveCoinInCache to return true for a spent
coin. It is more clear to keep the semantics the same. HaveCoinInCache is
used for two reasons:
- tracking coins we may want to uncache, in which case it is unlikely there
would be spent coins we could uncache (not dirty)
- optimistically checking whether we have already included a tx in the
blockchain, in which case a spent coin is not a reliable indicator that we have.

We can call gettxoutproof() with a list of transactions. Currently, if
the first transaction is unspent (and all other transactions are in the
same block), then the call will succeed. If the first transaction has
been spent, then the call will fail. The means that the following two
calls will return different results:
gettxoutproof(unspent_tx1, spent_tx1)
gettxoutproof(spent_tx1, unspent_tx1)
This commit makes behaviour independent of transaction ordering by looping
through all transactions provided and trying to find which block they're in.
This commit also increases the test coverage and tests more failure
cases for gettxoutproof()
Added an option to configure to allow for branch coverage statistics gathering.
Disabled logprint macro when coverage testing is on so that unnecessary branches are not analyzed.
The implementation of base_uint::operator++(int) and base_uint::operator--(int) is now safer.
Array pn is accessed via index i after bounds checking has been performed on the index, rather than before.
The logic of the while loops has also been made more clear.
A compile time assertion has been added in the class constructors to ensure that BITS is a positive multiple of 32.
CCoinsViewCache doesn't actually support cursor iteration returning the
current contents of the cache, so raise an error when the cursor method is
called instead of returning a cursor that iterates over stale data.
Also update the gettxoutsetinfo RPC which was relying on the old behavior to be
explicit about which view it is returning data about.
This adds a new CuckooCache in validation, caching whether all of a
transaction's scripts were valid with a given set of script flags.
Unlike previous attempts at caching an entire transaction's
validity, which have nearly universally introduced consensus
failures, this only caches the validity of a transaction's
scriptSigs. As these are pure functions of the transaction and
data it commits to, this should be much safer.
This is somewhat duplicative with the sigcache, as entries in the
new cache will also have several entries in the sigcache. However,
the sigcache is kept both as ATMP relies on it and because it
prevents malleability-based DoS attacks on the new higher-level
cache. Instead, the -sigcachesize option is re-used - cutting the
sigcache size in half and using the newly freed memory for the
script execution cache.
Transactions which match the script execution cache never even have
entries in the script check thread's workqueue created.
Note that the cache is indexed only on the script execution flags
and the transaction's witness hash. While this is sufficient to
make the CScriptCheck() calls pure functions, this introduces
dependancies on the mempool calculating things such as the
PrecomputedTransactionData object, filling the CCoinsViewCache, etc
in the exact same way as ConnectBlock. I belive this is a reasonable
assumption, but should be noted carefully.
In a rather naive benchmark (reindex-chainstate up to block 284k
with cuckoocache always returning true for contains(),
-assumevalid=0 and a very large dbcache), this connected blocks
~1.7x faster.

Prior to per-utxo CCoins, we checked that no other in-mempool tx
spent any of the given transaction's outputs, as we don't want to
uncache that entire tx in such a case. However, we now are checking
only that there exists no other mempool spends of the same output,
which should clearly be impossible after we removed the transaction
which was spending said output (barring massive mempool
inconsistency).
Thanks to @sdaftuar for the suggestion.
At startup, we choose one peer to serve us the headers chain, until
our best header is close to caught up. Disconnect this peer if more
than 15 minutes + 1ms/expected_header passes and our best header
is still more than 1 day away from current time.
This change has no effect on wallet behavior.
On wallet startup, the transaction scan avoids reading any blocks with
timestamps older than the wallet birthday (less than nTimeFirstKey -
TIMESTAMP_WINDOW). This block skipping code currently resides in
CWallet::ScanForWalletTransactions but it doesn't really belong there because
it makes the implementation unnecessarily fragile and hard to understand, and
it never has any effect except at startup (because all other callers do their
rescans based on timestamps other than, but always greater or equal to,
nTimeFirstKey).
This adds the listening address on which incoming connections were received to the
CNode and CNodeStats structures.
The address is reported in `getpeerinfo`.
This can be useful for distinguishing connections received on different listening ports
(e.g. when using a different listening port for Tor hidden service connections)
or different networks.

As the maximum amount of data that can be pulled into the cache due to
a block validation is much lower now (at most one CCoin entry per input
and per output), reduce the conservative estimate used to determine
flushing time.
This patch makes several related changes:
* Changes the CCoinsView virtual methods (GetCoins, HaveCoins, ...)
to be COutPoint/Coin-based rather than txid/CCoins-based.
* Changes the chainstate db to a new incompatible format that is also
COutPoint/Coin based.
* Implements reconstruction code for hash_serialized_2.
* Adapts the coins_tests unit tests (thanks to Russell Yanofsky).
A side effect of the new CCoinsView model is that we can no longer
use the (unreliable) test for transaction outputs in the UTXO set
to determine whether we already have a particular transaction.
This clarifies a bit more the ways in which the new script execution
cache could break consensus in the future if additional data from
the CCoins object were to be used as a part of script execution.
After this change, any such consensus breaks should be very visible
to reviewers, hopefully ensuring no such changes can be made.
The new functions are:
* CCoinsViewCache::AddCoin: Add a single COutPoint/Coin pair.
* CCoinsViewCache::SpendCoin: Remove a single COutPoint.
* AddCoins: utility function that invokes CCoinsViewCache::AddCoin for
each output in a CTransaction.
* AccessByTxid: utility function that searches for any output with
a given txid.
* CCoinsViewCache::AccessCoin: retrieve the Coin for a COutPoint.
* CCoinsViewCache::HaveCoins: check whether a non-empty Coin exists
for a given COutPoint.
The AddCoin and SpendCoin methods will eventually replace ModifyCoins
and ModifyNewCoins, AddCoins will replace CCoins::FromTx, and the new
AccessCoins and HaveCoins functions will replace their per-txid
counterparts.
Note that AccessCoin for now returns a copy of the Coin object. In a
later commit it will be change to returning a const reference (which
keeps working in all call sites).
The earlier CTxInUndo class now holds the same information as the Coin
class. Instead of duplicating functionality, replace CTxInUndo with a
serialization adapter for Coin.

Previously, transaction metadata (height, coinbase or not, and before
the previous commit also nVersion) was only stored for undo records
that correspond to the last output of a transaction being spent.
This only saves 2 bytes per undo record. Change this to storing this
information for every undo record, and stop complaining for having it
in non-last output spends. This means that undo dat written with
this patch won't be readable by older versions anymore.
This makes the following changes:
* In undo data and the chainstate database, the transaction nVersion
field is removed from the data structures, always written as 0, and
ignored when reading.
* The definition of hash_serialized in gettxoutsetinfo is changed to no
longer incude the nVersion field. It is renamed to hash_serialized_2
to avoid confusion. The new definition also includes transaction
height and coinbase information, as this information was missing
before.
This depends on having a CHashVerifier-based undo data checksum
verifier.
Apart from changing the definition of serialized_hash, downgrading
after using this patch is supported, as no release ever used the value
of nVersion field in UTXO entries.
This is necessary later, when we drop the nVersion field from the undo
data. At that point deserializing and reserializing the data won't
roundtrip anymore, and thus that approach can't be used to verify
checksums anymore.
With this CHashVerifier approach, we can deserialize while hashing the
exact serialized form that was used. This is both more efficient and
more correct in that case.
The error() function unconditionally reports an error. It should only
be used for actually exception situations, and not for the type of
inconsistencies that ApplyTxInUndo/DisconnectBlock can graciously deal
with.
This also makes a subtle semantics change: in ApplyTxInUndo, when a
record with metadata is encountered (indicating it is the last spend
from a tx), don't wipe the CCoins record if it wasn't empty at that
point. This makes sure that UTXO operations never affect any other
UTXOs (including those from the same tx).

A few code changes were needed to accompany the test:
* Adding setObjectName() calls for a few Qt controls to make them easily
accessible from the test.
* Calling contextMenu->popup() instead of contextMenu->exec() to open
the transaction list context menu without blocking the test thread.
* Opening the context menu at the contextualMenu event point rather than
the cursor position (this change was not strictly needed to make the test
work, but is more correct).
* Updating the bumped transaction row with showTransaction=true instead of
false. This is needed to prevent the bumped tx from being hidden, so the last
part of the test which attempts to bump the bumped tx can work. (Technically
this change is a more general bugfix not limited to the testing environment,
but the bug doesn't happen outside of the testing environment because in the
full Qt client, a queued NotifyTransactionChanged notification causes the row
to be updated twice, first with showTransaction=false, then immediately after
with showTransaction=true.)

Start importwallet rescans at the first block with timestamp greater or equal
to the wallet birthday instead of the last block with timestamp less or equal.
This fixes an edge case bug where importwallet could fail to start the rescan
early enough if there are blocks with decreasing timestamps or multiple blocks
with the same timestamp.

An off-by-one-block bug in importmulti rescan logic could cause it to return
success in an edge case even when a rescan was not successful. The case where
this would happen is if there were multiple blocks in a row with the same
GetBlockTimeMax() value, and the last block was scanned successfully, but one
or more of the earlier blocks was not readable.
Verbose is changed to an int. This can have values from 0-2 for each level of verbosity.
Verbosity level 2 has transaction details displayed in the results.
For the per confirmation number tracking of data, introduce a scale factor so that in the longer horizones confirmations are bucketed together at a resolution of the scale. (instead of 1008 individual data points for each fee bucket, have 42 data points each covering 24 different confirmation values.. (1-24), (25-48), etc.. )
Store in fee estimate file the block span for which we were tracking estimates, so we know what targets we can successfully evaluate with the data in the file. When restarting use either this historical block span to set valid range of targets until our current span of tracking estimates is just as long.
Track the first time we seen txs in a block that we have been tracking in our mempool. Used to evaluate validity of fee estimates for different targets.
Change the logic of estimateSmartFee to check a 60% threshold at half the target, a 85% threshold at the target and a 95% threshold at double the target. Always check the shortest time horizon possible and ensure that estimates are monotonically decreasing. Add a conservative mode, which makes sure that the 95% threshold is also met at longer time horizons as well.
Track information the ranges of fee rates that were used to calculate the fee estimates (the last range of fee rates in which the data points met the threshold and the first to fail) and provide an RPC call to return this information.
Instead of stopping if it encounters a "sufficient" number of transactions which don't meet the threshold for being confirmed within the target, it keeps looking to add more transactions to see if there is a temporary blip in the data. This allows a smaller number of required data points.

Rather than re-add disconnected block transactions back to the mempool
immediately, store them in a separate disconnectpool for later processing,
because we expect most such transactions to reappear in the chain that is
still to be connected (and thus we can avoid the work of reprocessing those
transactions through the mempool altogether).

CWalletDB now contains a CDB instead of inheriting from it.
This makes it easier to replace the internal transaction with a different
database, without leaking through internals.
Instead, CWalletDB() with a dummy handle will just give you a no-op
database in which writes always succeeds and reads always fail. CDB
already had functionality for this, so just use that.
Abstract database handle from explicit strFilename into
CWalletDBWrapper.
Also move CWallet::Backup to db.cpp - as it deals with representation
details this is a database specific operation.

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.

glibc-specific: On 32-bit systems set the number of arenas to 1. By
default, since glibc 2.10, the C library will create up to two heap
arenas per core. This is known to cause excessive virtual address space
usage in our usage. Work around it by setting the maximum number of
arenas to 1.

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.

Instead of having an exception propagate into the program when an
error happens while formatting a log message, just print a message to
the log.
Addresses #9423.
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.

`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`.

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

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

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.

ff25c32 mempool: add notification for added/removed entries (Wladimir J. van der Laan)
Analogue to ConnectTrace that tracks transactions that have been removed from the mempool due to conflicts and then passes them through SyncTransaction at the end of its scope.
Add notification signals to make it possible to subscribe to mempool
changes:
- NotifyEntryAdded(CTransactionRef)>
- NotifyEntryRemoved(CTransactionRef, MemPoolRemovalReason)>
Also add a mempool removal reason enumeration, which is passed to the
removed notification based on why the transaction was removed from
the mempool.

Prior to this commit the err variable was not guaranteed to be set before
the check ...
BOOST_CHECK_MESSAGE(err != SCRIPT_ERR_OK, ScriptErrorString(err));
This adds a comment to the new logic for setting HB peers based
on block validation (and aligns the code below to reflect the comment).
It's not obvious why we're checking mapBlocksInFlight. Add a comment to
explain.
The additional initializer is for the named arguments, which are unused
in the test (and unfilled global fields will be initialized to 0
anyhow), so this is a no-op apart from the warning.

( 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.

to (usage > 0.9 * space && usage > space - 100MB). This means we're not

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

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.

Before daemonization, just probe the data directory lock and print an

After daemonization get the data directory lock again and hold on to it until exit
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.
Bring up the modal progress overlay when the user clicks the spinner

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

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.

- 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).

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.
