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.
These warnings are removed from autogen output:

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.

5a6d00c Permit disconnection of outbound peers on bad/slow chains (Suhas Daftuar)
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.

A peer could try to waste our resources by sending us unrequested blocks with
low work, eg to fill up our disk. Since
e2652002b6 we no longer request blocks until we
know we're on a chain with more than nMinimumChainWork (our anti-DoS
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
can create them by manually copying database files.

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()

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.

Sending a getheaders message with an empty locator and a stop hash

requests for headers on side branches that are too old.

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 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.

It essentially breaks up two wrapper functions for things only used in one place (ConnectSocketDirectly/ConnectThroughProxy) in favor of calling them directly. This allows us to fully handle resolves before attempting a connection, as is necessary for async connections.
As a bonus, I believe the logic is now much easier to follow than before.

8502b20 Unify help text for GetWarnings output in get*info RPCs (Andrew Chow)
f77f0e4 Add warnings field to getblockchaininfo (Andrew Chow)
Pull request description:
The `getblockchaininfo` output does not contain the `errors` field which the `getinfo`, `getmininginfo`, and `getnetworkinfo` RPCs have. It should have it as the errors pertain to the blockchain. This PR adds that field.
This PR also unifies the help text for the `errors` field and its output position so that all of the `get*info` commands are consistent.
`getnetworkinfo`'s `errors` field is named `warnings`. I did not change this even though it is inconsistent since this naming has been in use for a long time.

5e69a43 Add test for bitcoin-cli -getinfo (John Newbery)
3826253 rpc: Handle `getinfo` locally in bitcoin-cli w/ `-getinfo` (Wladimir J. van der Laan)
Pull request description:
Since @laanwj doesn't want to maintain these changes anymore, I will.
This PR is a revival of #8843. I have addressed @jnewbery's comments.
Regarding atomicity, I don't think that is a concern here. This is explicitly a new API and those who use it will know that this is different and that it is not atomic.

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.

Changes the errors field to warnings. To maintain compatibility,
the errors field is deprecated and enabled by starting bitcoind with
-deprecatedrpc=getmininginfo
048e0c3e2 [rpc] [tests] Add deprecated RPC test (Cristian Mircea Messel)
d4cdbd6fb [rpc] Deprecate estimatefee RPC (John Newbery)
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.
