6b25f29a91 Use std::vector API for construction of test data. (Daniel Kraft)
Pull request description:
For constructing test scripts, use `std::vector` and, in particular, `std::vector::insert` to insert 20 zero bytes rather than listing the full array of bytes explicitly. This makes the code easier to read and makes it immediately obvious what the structure of the data is, without having to count the zeros to understand it.
Of course, that is a matter of taste - so if you disagree that the change makes the code easier to read, let me know.
This has been split out of #14752.

Pull request description:
Motivated by https://github.com/bitcoin/bitcoin/pull/11913#discussion_r157798157, this pull makes `blockToJSON` and `blockheaderToJSON` free of `cs_main` locks.
Locking `cs_main` was required to access `chainActive` in order to check if the block was in the chain and to retrieve the next block index.
With the this approach, `CBlockIndex::GetAncestor()` is used in a way to check if the block belongs to the specified chain tip and, at the same time, get the next block index.

Instead I run it with PROTOCOL_VERSION and 0 separately, as the original

version 0.

8db0c3d42b Removed implicit CTransaction conversion from benchmaks (lucash-dev)
ed61abedb2 Removed implicit CTransaction constructor from tests (lucash-dev)
Pull request description:
This PR was split from #14906 and is a prerequisite for it.
It updates tests and benchmarks, removing all implicit calls to `CTransaction(CMutableTransaction&)` constructors. This will make possible making the constructor explicit in the next PR.
The original rationale for making the constructor explicit:
- Conversion constructors should not be explicit unless there's a strong reason for it (in the opinion of, for example, https://google.github.io/styleguide/cppguide.html, and https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Ro-conversion. Let me know your take on this).
- This particular conversion is very costly -- it implies a serialization plus hash of the transaction.
- Even though `CTransaction` and `CMutableTransaction` represent the same data, they have very different use cases and performance properties.
- Making it explicit allows for easier reasoning of performance trade-offs.
- There has been previous performance issues caused by unneeded use of this implicit conversion.
- This PR creates a map for places to look for possible refactoring and performance gains (this benefit still holds if the PR is not merged).

6be0fb4b3 [refactor] Add a base DescriptorImpl with most common logic (Pieter Wuille)
Pull request description:
This patch modifies the internal `Descriptor` class to optionally construct and use an "expansion cache". Such a cache is a byte array that encodes all information necessary to expand a `Descriptor` a second time without access to private keys, and without the need to perform expensive BIP32 derivations. For all currently defined descriptors, the cache simply contains a concatenation of all public keys used.
This is motivated by the goal of importing a descriptor into the wallet and using it as a replacement for the keypool, where it would be impossible to expand descriptors if they use hardened derivation.

bf2e01097 uint256: Remove unnecessary crypto/common.h use (Karl-Johan Alm)
Pull request description:
This is an alternative to #13242 which keeps the `ReadLE64` part, but moves the `crypto/common.h` dependency into `crypto/common.h` as a function outside of `uint256`.
**Reason:** this change will remove dependencies for `uint256` to `crypto/common.h`, `compat/endian.h`, and `compat/byteswap.h`.
This PR removes the need to update tests to be endian-aware/-independent, but keeps the (arguably dubious) `ReadLE64` part (which was only introduced to fix the tests, not for any functionality).

Pull request description:
This PR adds functionality to convert a script to a descriptor, given a `SigningProvider` with the relevant information about public keys and redeemscripts/witnessscripts.
The feature is exposed in `listunspent`, `getaddressinfo`, and `scantxoutset` whenever these calls are applied to solvable outputs/addresses.
This is not very useful on its own, though when we add RPCs to import descriptors, or sign PSBTs using descriptors, these strings become a compact and standalone way of conveying everything necessary to sign an output (excluding private keys).
Unit tests and rudimentary RPC tests are included (more relevant tests can be added once RPCs support descriptors).
Fixes#14503.

Reachable from either place where SetIP is used when all of:

- the peer tells us it's reaching us at an IPv6 address
- NET logging is enabled
In that case, SetIP turns an IPv4 address into an IPv6 address without
setting the scopeId, which is subsequently read in GetSockAddr during
CNetAddr::ToStringIP and passed to getnameinfo. Fix by ensuring every
constructor initializes the scopeId field with something.

Pull request description:
Based on conversation in #13462, it seems the serialization `GetType` has very narrow use/effect. In every case except for `CAddress`, which specifically relates to a network peer's address, not a wallet address etc., the serialized representation of an object is irrespective of its destination / type.
This removes the unused `GetType` method from `CSizeComputer` as a step to further narrowing that use.

Pull request description:
Remove unreferenced local variables:
Increase signal to noise in appveyor build output by reducing the MSVC warning count from 12 to 4. 12 is the number of MSVC warnings under our current appveyor setup assuming the changes in #14086 are also implemented.
This makes it easier to spot errors or more important warnings in the verbose appveyor output. MSVC warnings are good, so having access to them in a noise free way (read: without trivial warnings) via appveyor without having to use Windows is really valuable.

Call sync.h primitives "locks" and "mutexes" instead of "blocks" and "waitable
critical sections" to match current coding conventions and c++11 standard
names.
This PR does not rename the "CCriticalSection" class (though this could be done
as a followup) because it is used everywhere and would swamp the other changes
in this PR. Plain mutexes should mostly be preferred instead of recursive
mutexes in new code anyway.

These assertions were introduced quite recently (in #14069 which was merged two days ago) and since this is a recurring thing (see #13534 – "Don't assert(foo()) where foo() has side effects" from May) I added a simple regression test for the most obvious common side effect.

7a208d9fad Implements custom tolower and toupper functions. (251)
e2ba043b8d Implements ParseNetwork unit test. (251)
Pull request description:
This pull request removes the `boost/algorithm/string/case_conv.hpp` dependency from the project.
`boost/algorithm/string/case_conv.hpp` is included for the `boost::to_lower` and `boost::to_upper` template functions.
We can replace the calls to these functions with straightforward alternative implementations that use the C++ Standard Library, because the functions are called with `std::string` objects that use standard 7-bit ASCII characters as argument.
The refactored implementation should work without the explicit `static_cast<unsigned char>` cast and `unsigned char` lambda return type. Both have been added defensively and to be explicit. Especially in case of the former, behaviour is undefined (potentially result in a crash) if the `std::toupper` argument is not an `unsigned char`.
A potential alternative, maybe even preferred, implementation to address the `boost::to_lower` function call in `ParseNetwork(std::string)` could have been:
```c++
if (net == "ipv4" || net == "IPv4") return NET_IPV4;
if (net == "ipv6" || net == "IPv6") return NET_IPV6;
```
This alternative implementation would however change the external behaviour of `ParseNetwork(std::string)`.
This pull requests includes a unit test to validate the implementation of `ParseNetwork(std::string)` prior and after the removal of the `case_conv.hpp` dependency.
`boost/algorithm/string/case_conv.hpp` has been removed from the `EXPECTED_BOOST_INCLUDES` in `test/lint/lint-includes.sh` because it is no longer required.

This commit implements custom equivalents for the C and C++ `tolower` and `toupper` Standard Library functions.
In addition it implements a utility function to capitalize the first letter of a string.

Pull request description:
This implements the compact block filter construction in [BIP 158](https://github.com/bitcoin/bips/blob/master/bip-0158.mediawiki). The code is not used anywhere in the Bitcoin Core code base yet. The next step towards [BIP 157](https://github.com/bitcoin/bips/blob/master/bip-0157.mediawiki) support would be to create an indexing module similar to `TxIndex` that constructs the basic and extended filters for each validated block.
### Filter Sizes
[Here](https://gateway.ipfs.io/ipfs/QmRqaAAQZ5ZX5eqxP7J2R1MzFrc2WDdKSWJEKtQzyawqog) is a CSV of filter sizes for blocks in the main chain.
As you can see below, the ratio of filter size to block size drops after the first ~150,000 blocks:
The reason for the relatively large filter sizes is that Golomb-coded sets only achieve good compression with a sufficient number of elements. Empirically, the average element size with 100 elements is 14% larger than with 10,000 elements.
The ratio of filter size to block size is computed without witness data for basic filters. Here is a summary table of filter size ratios *for blocks after height 150,000*:
| Stat | Filter Type |
|-------|--------------|
| Weighted Size Ratio Mean | 0.0198 |
| Size Ratio Mean | 0.0224 |
| Size Ratio Std Deviation | 0.0202 |
| Mean Element Size (bits) | 21.145 |
| Approx Theoretical Min Element Size (bits) | 21.025 |

This PR instead uses the value of the 50th percentile weight unit in the block, and also calculates the feerate at the 10th, 25th, 75th, and 90th percentiles. This more accurately corresponds with what is generally meant by median feerate.

48b1473c89 Use 71 byte signature for DUMMY_SIGNATURE_CREATOR (Andrew Chow)
18dfea0dd0 Always create 70 byte signatures with low R values (Andrew Chow)
Pull request description:
When creating signatures for transactions, always make one which has a 32 byte or smaller R and 32 byte or smaller S value. This results in signatures that are always less than 71 bytes (32 byte R + 32 byte S + 6 bytes DER + 1 byte sighash) with low R values. In most cases, the signature will be 71 bytes.
Because R is not mutable in the same way that S is, a low R value can only be found by trying different nonces. RFC 6979 for deterministic nonce generation has the option to specify additional entropy, so we simply use that and add a uin32_t counter which we increment in order to try different nonces. Nonces are sill deterministically generated as the nonce used will the be the first one where the counter results in a nonce that results in a low R value. Because different nonces need to be tried, time to produce a signature does increase. On average, it takes twice as long to make a signature as two signatures need to be created, on average, to find one with a low R.
Having a fixed size signature makes size calculations easier and also saves half a byte of transaction size, on average.
DUMMY_SIGNATURE_CREATOR has been modified to produce 71 byte dummy signatures instead of 72 byte signatures.

Removes medianfeerate result from getblockstats.
Adds feerate_percentiles which give the feerate of the 10th, 25th, 50th,
75th, and 90th percentile weight unit in the block.
When extra entropy is not specified by the caller, CKey::Sign will
now always create a signature that has a low R value and is at most
70 bytes. The resulting signature on the stack will be 71 bytes when
the sighash byte is included.
Using low R signatures means that the resulting DER encoded signature
will never need to have additional padding to account for high R
values.

Pull request description:
As discussed in #13023 I've split this test out into a separate pr
This test (and documentation update) makes explicit the guarantee (previously undefined, but implied by the 'SingleThreaded' in `SingleThreadedSchedulerClient()`) - that callbacks pushed to the `SingleThreadedSchedulerClient()` obey the single threaded model for memory and execution - specifically, the callbacks are executed fully and in order, and even in cases where a subsequent callback is executed by a different thread, sequential consistency of memory for all threads executing these callbacks is maintained.
Maintaining memory consistency should make the api more developer friendly - especially for users of the validationinterface. To the extent that there are performance implications from this decision, these are not currently present in practice because all use of this scheduler happens on a single thread currently, furthermore the lock should guarantee consistency across callback executions even when callbacks are executed by multiple threads (as the test does).

e3245f2e7b Removes Boost predicate.hpp dependency (251)
Pull request description:
This pull request removes the `boost/algorithm/string/predicate.hpp` dependency from the project.
To replace the the `predicate.hpp` dependency from the project the function calls to `boost::algorithm::starts_with` and `boost::algorithm::ends_with` have been replaced with respectively C++11's `std::basic_string::front` and `std::basic_string::back` function calls.
Refactors that were not required, but have been done anyways:
- The Boost function `all` was implicitly made available via the `predicate.hpp` header. Instead of including the appropriate header, function calls to `all` have been replaced with function calls to `std::all_of`.
- The `boost::algorithm::is_digit` predicate has been replaced with a custom `IsDigit` function that is locale independent and ASCII deterministic.

Because false is synonymous with TX_NONSTANDARD, this conveys the same
information and makes the handling explicitly based on script type,
simplifying each call site.
Prior to this change it was common for the return value to be ignored,
or for the return value and TX_NONSTANDARD to be redundantly handled.
This is a squashed commit that squashes the following commits:
This commit removes the `boost/algorithm/string/predicate.hpp` dependenc
from the project by replacing the function calls to `boost::algorithm::starts_with`
`boost::algorithm::ends_with` and `all` with respectively C++11'
`std::basic_string::front`, `std::basic_string::back`, `std::all_of` function calls
This commit replaces `boost::algorithm::is_digit` with a locale independent isdigi
function, because the use of the standard library's `isdigit` and `std::isdigit
functions is discoraged in the developer notes
417b6c1d29 bitcoinconsensus: invalid flags should be set to bitcoinconsensus_error type, add test cases covering bitcoinconsensus error codes (Thomas Kerin)
Pull request description:
A check was added to the bitcoinconsensus verify_script codepath to ensure that callers only used _exposed_ interpreter flags. I think this error should be written to `bitcoinconsensus_err* err` and not returned by verify_script?
I modified the check so it indicates the error using *err like the others, and added tests covering the error codes.

Pull request description:
As part of a larger effort to decouple net_processing and validation a bit, these are a bunch of simple scope cleanups. I've moved things out of the header file that are only referenced in net_processing and added static (or anonymous namespace) modifiers to everything possible in net_processing.
There are a handful of functions which could be static except that they are exposed for the sake of unit testing - these are explicitly commented. There has been some discussion of a compile time annotation, but no conclusion has been reached on that yet.
This is somewhat related to other prs #12934#13413#13407 and will be followed by prs that reduce reliance on cs_main to synchronize data structures which are translation unit local to net_processing

ed94c8b55 Replace CombineSignatures with ProduceSignature (Andrew Chow)
0422beb9b Make SignatureData able to store signatures and scripts (Andrew Chow)
b6edb4f5e Inline Sign1 and SignN (Andrew Chow)
Pull request description:
Currently CombineSignatures is used to create the final scriptSig or an input. However ProduceSignature is capable of doing this itself. Using both CombineSignatures and ProduceSignature results in code duplication which is unnecessary.
To move the scriptSig construction to ProduceSignatures, the SignatureData class contains two maps to hold pubkeys mapped to signatures, and script ids mapped to scripts. DataFromTransaction is extended to be able to extract signatures, their public keys, and scripts from existing ScriptSigs.
The SignaureData are then passed down to SignStep which can use the aforementioned maps to get the signatures, pubkeys, and scripts that it needs, falling back to the actual SigningProvider and SignatureCreator if the data are not available in the SignatureData.
Additionally, Sign1 and SignN have been removed and their functionality inlined into SignStep since Sign1 is really just a wrapper around CreateSig.
Since ProduceSignature can produce the final scriptSig or scriptWitness by using SignatureData which has extracted data from the transaction, CombineSignatures is unnecessary as ProduceSignature is able to replicate all of CombineSignatures' functionality.
This also furthers BIP 174 support and begins moving towards a BIP 174 style backend.
The tests have also been updated to use the new combining methodology.

07c493f2d scripted-diff: Replace NET_TOR with NET_ONION (wodry)
Pull request description:
This is a follow-up to #13532, where @promag already asked if this renaming would make sense.
If network shall be named _Onion_ instead of _Tor_ (like in the option `onlynet`), renaming the network enum NET_TOR to NET_ONION maybe would make sense and be stringent.
Change was produced with the following script:
```
#!/bin/bash
for file in $(grep --exclude-dir='.git' --files-with-matches --binary-files=without-match --recursive NET_TOR bitcoin/)
do
sed --in-place --expression='s/NET_TOR/NET_ONION/g' $file
done
```
_Tor_ is used at many other places in the code, though.

* In https://github.com/bitcoin/bitcoin/pull/13142#issuecomment-386396975 it was suggested to merge `isInvalid` into the return status. This PR takes a different approach, and removes the `isInvalid` entirely. It was only ever used inside tests, as normal users of IsMine don't care about the reason for non-mine-ness, only whether it is or not. As the unit tests are extensive enough, it seems sufficient to have a black box text (with tests for both compressed and uncompressed keys).
Some addition code simplification is done as well.

In addition to having the scriptSig and scriptWitness, have SignatureData
also be able to store just the signatures (pubkeys mapped to sigs) and
scripts (script ids mapped to scripts).
Also have DataFromTransaction be able to extract signatures and scripts
from the scriptSig and scriptWitness of an input to put them in SignatureData.
Adds a new SignatureChecker which takes a SignatureData and puts pubkeys
and signatures into it when it successfully verifies a signature.
Adds a new field in SignatureData which stores whether the SignatureData
was complete. This allows us to also update the scriptSig and
scriptWitness to the final one when updating a SignatureData with another
one.

This presumably slows down rescan, which uses a `CTransaction` and its `GetHash`, but never uses the `GetWitnessHash`. The slow down is proportional to the number of witness transactions in the rescan window. I.e. early in the chain there should be no measurable slow down. Later in the chain, there should be a slow down, but acceptable given the speedups in the modules mentioned above.

Pull request description:
Originally this PR was just to add tests around concurrency in block validation - those tests seem to have uncovered another bug in ActivateBestChain - this now fixes that bug and adds tests.
ActivateBestChain (invoked after a new block is validated) proceeds in steps - acquiring and releasing cs_main while incrementally disconnecting and connecting blocks to sync to the most work chain known (FindMostWorkChain()). Every time cs_main is released the result of FindMostWorkChain() can change - but currently that value is cached across acquisitions of cs_main and only refreshed when an invalid chain is explored. It needs to be refreshed every time cs_main is reacquired. The test added in 6094ce7304 will occasionally fail without the commit fixing this issue 26bfdbaddb
Original description below
--
After a bug discovered where UpdatedBlockTip() notifications could be triggered out of order (#12978), these unit tests check certain invariants about these signals.
The scheduler test asserts that a SingleThreadedSchedulerClient processes callbacks fully and sequentially.
The block validation test generates a random chain and calls ProcessNewBlock from multiple threads at random and in parallel. ValidationInterface callbacks verify that the ordering of BlockConnected BlockDisconnected and UpdatedBlockTip events occur as expected.

Pull request description:
Currently our wallet code will treat bare multisig outputs (meaning scriptPubKeys with multiple public keys + `OP_CHECKMULTISIG` operator in it) as ours without the user asking for it, as long as all private keys in it are in our wallet.
This is a pointless feature. As it only works when all private keys are in one place, it's useless compared to single key outputs (P2PK, P2PKH, P2WPKH, P2SH-P2WPKH), and worse in terms of space, cost, UTXO size, and ability to test (due to lack of address format for them).
Furthermore, they are problematic in that producing a list of all `scriptPubKeys` we accept is not tractable (it involves all combinations of all public keys that are ours). In further wallet changes I'd like to move to a model where all scriptPubKeys that are treated as ours are explicit, rather than defined by whatever keys we have. The current behavior of the wallet is very hard to model in such a design, so I'd like to get rid of it.
I think there are two options:
* Remove it entirely (do not ever accept bare multisig outputs as ours, unless watched)
* Only accept bare multisig outputs in situations where the P2SH version of that output would also be acceptable
This PR implements the first option. The second option was explored in #12874.

This PR moves `FindAndDelete` and `GetOp2` out of CScript (the first is only used inside the interpreter and moved there, the second does not actually depend on any script specifics and works on any vector). Furthermore, all non-const-iterator versions of GetOp are replaced by const ones, removing a number of methods in the process.
The longer term goal here is making the script interpreter independent from the CScript representation.
Note for reviewers: both `FindAndDelete` and `GetScriptOp` are consensus critical.

Such outputs can still be watched, and signed for, but they aren't treated as valid payments.
That means they won't cause transactions to appear in listtransactions, their outputs to be
shown under listunspent, or affect balances.
Seems providing at least minimal visibility to the failure is a good practice.
The only remaining ignored state is in LoadExternalBlockFile, where logging
would likely be spammy.

The weekly meeting on [2017-12-07](http://www.erisian.com.au/meetbot/bitcoin-core-dev/2017/bitcoin-core-dev.2017-12-07-19.00.log.html) discussed allowing options to bitcoin to have some sensitivity to what network is in use. @theuni suggested having sections in the config file:
<cfields> an alternative to that would be sections in a config file. and on the
cmdline they'd look like namespaces. so, [testnet] port=5. or -testnet::port=5.
This approach is (more or less) supported by `boost::program_options::detail::config_file_iterator` -- when it sees a `[testnet]` section with `port=5`, it will treat that the same as "testnet.port=5". So `[testnet] port=5` (or `testnet.port=5` without the section header) in bitcoin.conf and `-testnet.port=5` on the command line.
The other aspect to this question is possibly limiting some options so that there is no possibility of accidental cross-contamination across networks. For example, if you're using a particular wallet.dat on mainnet, you may not want to accidentally use the same wallet on testnet and risk reusing keys.
I've set this up so that the `-addnode` and `-wallet` options are `NETWORK_ONLY`, so that if you have a bitcoin.conf:
wallet=/secret/wallet.dat
upnp=1
and you run `bitcoind -testnet` or `bitcoind -regtest`, then the `wallet=` setting will be ignored, and should behave as if your bitcoin.conf had specified:
upnp=1
[main]
wallet=/secret/wallet.dat
For any `NETWORK_ONLY` options, if you're using `-testnet` or `-regtest`, you'll have to add the prefix to any command line options. This was necessary for `multiwallet.py` for instance.
I've left the "default" options as taking precedence over network specific ones, which might be backwards. So if you have:
maxmempool=200
[regtest]
maxmempool=100
your maxmempool will still be 200 on regtest. The advantage of doing it this way is that if you have `[regtest] maxmempool=100` in bitcoin.conf, and then say `bitcoind -regtest -maxmempool=200`, the same result is probably in line with what you expect...
The other thing to note is that I'm using the chain names from `chainparamsbase.cpp` / `ChainNameFromCommandLine`, so the sections are `[main]`, `[test]` and `[regtest]`; not `[mainnet]` or `[testnet]` as might be expected.

When a -nofoo option is seen, instead of adding it to a separate
set of negated args, set the arg as being an empty vector of strings.
This changes the behaviour in some ways:
- -nofoo=0 still sets foo=1 but no longer treats it as a negated arg
- -nofoo=1 -foo=2 has GetArgs() return [2] rather than [2,0]
- "foo=2 \n -nofoo=1" in a config file no longer returns [2,0], just [0]
- GetArgs returns an empty vector for negated args

Pull request description:
This runs the unit tests (`src/test/test_bitcoin`) in 4 separate simultaneous processes, significantly speeding up some Travis runs (over 2x for win32).
This uses an approach by @theuni that relies on `make` as the mechanism for distributing tests over processes (through `-j`). For every test .cpp file, we search for `BOOST_FIXTURE_TEST_SUITE` or `BOOST_AUTO_TEST_SUITE`, and then invoke the test binary for just that suite (using `-t`). The (verbose) output is stored in a temporary file, and only shown in the case of failure.
Some makefile reshuffling is necessary to avoid trying to run tests from `src/test/test_bitcoin.cpp` for example, which contains framework/utility code but no real tests.
Finally, order the Travis jobs from slow to fast (apart from the arm/doc job which goes first, for fast failure). This should help reducing the total wall clock time before opening a PR and finishing Travis, in case where not all jobs are started simultaneously.
This is an alternative to #12831.

f7683cba7b Track negated arguments in the argument paser. (Evan Klitzke)
4f872b2450 Add additional tests for GetBoolArg() (Evan Klitzke)
Pull request description:
This change explicitly enable tracking negated options in the option parser. A negated option is one passed with a `-no` prefix. For example, `-nofoo` is the negated form of `-foo`. Negated options were originally added in the 0.6 release.
The change here allows code to explicitly distinguish between cases like `-nofoo` and `-foo=0`, which was not possible previously. The option parser does not have any changed semantics as a result of this change, and existing code will parse options just as it did before.
The motivation for this change is to provide a way to disable options that are otherwise not boolean options. For example, the `-debuglogfile` option is normally interpreted as a string, where the value is the log file name. With this change a user can pass in `-nodebuglogfile` and the code can see that it was explicitly negated, and use that to disable the log file.
This change originally split out from #12689.

> * conventional enums export their enumerators to the surrounding scope, causing name clashes.
> * the underlying type of an enum cannot be specified, causing confusion, compatibility problems, and makes forward declaration impossible.

> The new enums are "enum class" because they combine aspects of traditional enumerations (names values) with aspects of classes (scoped members and absence of conversions).

Using VARINT with signed types is dangerous because negative values will appear
to serialize correctly, but then deserialize as positive values mod 128.
This commit changes the VARINT macro to trigger an error by default if called
with an signed value, and updates broken uses of VARINT to pass a special flag
that lets them keep working with no change in behavior.

* A dictionary does not guarantee that keys are sorted. Again, a user needs to keep this in mind, as it could eventually lead to excessive tx fees.

e68172ed9 Add test-before-evict discipline to addrman (Ethan Heilman)
Pull request description:
This change implement countermeasures 3 (test-before-evict) suggested in our paper: ["Eclipse Attacks on Bitcoin’s Peer-to-Peer Network"](http://cs-people.bu.edu/heilman/eclipse/).
# Design:
A collision occurs when an address, addr1, is being moved to the tried table from the new table, but maps to a position in the tried table which already contains an address (addr2). The current behavior is that addr1 would evict addr2 from the tried table.
This change ensures that during a collision, addr1 is not inserted into tried but instead inserted into a buffer (setTriedCollisions). The to-be-evicted address, addr2, is then tested by [a feeler connection](https://github.com/bitcoin/bitcoin/pull/8282). If addr2 is found to be online, we remove addr1 from the buffer and addr2 is not evicted, on the other hand if addr2 is found be offline it is replaced by addr1.
An additional small advantage of this change is that, as no more than ten addresses can be in the test buffer at once, and addresses are only cleared one at a time from the test buffer (at 2 minute intervals), thus an attacker is forced to wait at least two minutes to insert a new address into tried after filling up the test buffer. This rate limits an attacker attempting to launch an eclipse attack.
# Risk mitigation:
- To prevent this functionality from being used as a DoS vector, we limit the number of addresses which are to be tested to ten. If we have more than ten addresses to test, we drop new addresses being added to tried if they would evict an address. Since the feeler thread only creates one new connection every 2 minutes the additional network overhead is limited.
- An address in tried gains immunity from tests for 4 hours after it has been tested or successfully connected to.
# Tests:
This change includes additional addrman unittests which test this behavior.
I ran an instance of this change with a much smaller tried table (2 buckets of 64 addresses) so that collisions were much more likely and observed evictions.

# Security Benefit
This is was originally posted in PR #8282 see [this comment for full details](https://github.com/bitcoin/bitcoin/pull/8282#issuecomment-237255215).
To determine the security benefit of these larger numbers of IPs in the tried table I modeled the attack presented in [Eclipse Attacks on Bitcoin’s Peer-to-Peer Network](https://eprint.iacr.org/2015/263).
**Default node:** 595 attacker IPs for ~50% attack success.
**Default node + test-before-evict:** 620 attacker IPs for ~50% attack success.
**Feeler node:** 5540 attacker IPs for ~50% attack success.
**Feeler node + test-before-evict:** 8600 attacker IPs for ~50% attack success.
The node running feeler connections has 10 times as many online IP addresses in its tried table making an attack 10 times harder (i.e. requiring the an attacker require 10 times as many IP addresses in different /16s). Adding test-before-evict increases resistance of the node by an additional 3000 attacker IP addresses.
Below I graph the attack over even greater attacker resources (i.e. more attacker controled IP addresses). Note that test-before-evict maintains some security far longer even against an attacker with 50,000 IPs. If this node had a larger tried table test-before-evict could greatly boost a nodes resistance to eclipse attacks.

9ad6746ccd Use static_cast instead of C-style casts for non-fundamental types (practicalswift)
Pull request description:
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.
For a more thorough discussion, see ["ES.49: If you must use a cast, use a named cast"](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#es49-if-you-must-use-a-cast-use-a-named-cast) in the C++ Core Guidelines (Stroustrup & Sutter).

0c8ea6380 Abstract out IsSolvable from Witnessifier (Pieter Wuille)
Pull request description:
This implements a minimum viable implementation of SegWit wallet support, based on top of #11389, and includes part of the functionality from #11089.
Two new configuration options are added:
* `-addresstype`, with options `legacy`, `p2sh`, and `bech32`. It controls what kind of addresses are produced by `getnewaddress`, `getaccountaddress`, and `createmultisigaddress`.
* `-changetype`, with the same options, and by default equal to `-addresstype`, that controls what kind of change is used.
All wallet private and public keys can be used for any type of address. Support for address types dependent on different derivation paths will need a major overhaul of how our internal detection of outputs work. I expect that that will happen for a next major version.
The above also applies to imported keys, as having a distinction there but not for normal operations is a disaster for testing, and probably for comprehension of users. This has some ugly effects, like needing to associate the provided label to `importprivkey` with each style address for the corresponding key.
To deal with witness outputs requiring a corresponding redeemscript in wallet, three approaches are used:
* All SegWit addresses created through `getnewaddress` or multisig RPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a witness address will work, as long as the wallet file is up to date.
* All SegWit keys in the wallet get an _implicit_ redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software.
* All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a witness address will work.
These approaches correspond to solutions 3a, 1a, and 5a respectively from https://gist.github.com/sipa/125cfa1615946d0c3f3eec2ad7f250a2. As argued there, there is no full solution for dealing with the case where you both downgrade and restore a backup, so that's also not implemented.
`dumpwallet`, `importwallet`, `importmulti`, `signmessage` and `verifymessage` don't work with SegWit addresses yet. They're remaining TODOs, for this PR or a follow-up. Because of that, several tests unexpectedly run with `-addresstype=legacy` for now.

3e1ee31 [Tests] Adding unit tests for GetDifficulty in blockchain.cpp. (sean)
Pull request description:
blockchain.cpp has low unit test coverage. This commit is intended
to start improving its code coverage to reasonable levels. One or more
follow up commits will complete the task that this commit is starting
(though the usefulness of this commit is not dependent upon later
commits).
Note that these tests were not written based upon a specification of how
GetDifficulty *should* work, but rather how it actually *does* work. As
a result, if there are any bugs in the current GetDifficulty
implementation, these unit tests serve to lock them in rather than
expose them.
-- Why has blockchain.cpp been modified if this is a unit testing change?
Since the existing GetDifficulty function relies on a global variable,
chainActive, it was not suitable for unit testing purposes. Both the
existing GetDifficulty function and the unit tests now call through to
a new, more modular version of GetDifficulty that can work on any chain,
not just chainActive.
-- Why does blockchain_tests.cpp directly include blockchain.cpp instead
of blockchain.h?
While the new GetDifficulty function's signature is arguably better than
the old one's, it still isn't great, and doesn't seem to warrant inclusion
as part of the blockchain.h API, especially since only test code is
directly using it. If a better way of exposing the new GetDifficulty
function to unit tests exists, please mention it and the commit will be
updated accordingly.
-- Why is the test fixture named blockchain_difficulty_tests rather than
blockchain_tests?
The Bitcoin Core policy for naming unit test files is to match the the
file under test ("blockchain" becomes "blockchain_tests"). While this
commit complies with that, blockchain.cpp is a massive file, such that
having all of the unit tests in one file will tend towards disorder.
Since there will be a lot more tests added to this file, the intention
is to divide up different types of tests into different test fixtures
within the same file.

2862b56 [tests] remove redundant univalue_tests.cpp (John Newbery)
Pull request description:
univalue unit tests were added in #4730 , and exist at `/src/test/univalue_tests.cpp` (outside the univalue tree). That test was brought into the univalue repository in https://github.com/bitcoin-core/univalue/pull/4 , which was pulled into the github repository in https://github.com/bitcoin/bitcoin/pull/11420.
That means that the univalue test exists in two places:
1. `/src/test/univalue_tests.cpp`
2. `/src/univalue/test/object.cpp`
(2) is a strict superset of (1). It adds some macros to work around boost not being a univalue dependency, and adds a few extra lines of test.
Therefore remove `/src/test/univalue_tests.cpp`

12781db [Tests] check specific validation error in miner tests (Sjors Provoost)
Pull request description:
## Problem
`BOOST_CHECK_THROW` merely checks that some `std::runtime_error` is
thrown, but not which one.
Here's an example of how this can cause a test to pass when a developer
introduces a consensus bug. The test for the sigops limit assumes
that `CreateNewBlock` fails with `bad-blk-sigops`. However it can
also fail with bad-txns-vout-negative, if a naive developer lowers
`BLOCKSUBSIDY` to `1*COIN`.
## Solution
`BOOST_CHECK_EXCEPTION` allows an additional predicate function. This
commit uses this for all exceptions that are checked for in
`miner_tets.cpp`:
* `bad-blk-sigops`
* `bad-cb-multiple`
* `bad-txns-inputs-missingorspent`
* `block-validation-failed`
If the function throws a different error, the test will fail. Although the message produced by Boost is a bit [confusing](http://boost.2283326.n4.nabble.com/Test-BOOST-CHECK-EXCEPTION-error-message-still-vague-tt4683257.html#a4683554), it does show which error was actually thrown. Here's what the above `1*COIN` bug would result in:
<img width="1134" alt="schermafbeelding 2017-09-02 om 23 42 29" src="https://user-images.githubusercontent.com/10217/29998976-815cabce-9038-11e7-9c46-f5f6cfb0ca7d.png">
## Other considerations
A more elegant solution in my opinion would be to subclass `std::runtime_error` for each `INVALID_TRANSACTION` type, but this would involve touching consensus code.
I put the predicates in `test_bitcoin.h` because I assume they can be reused in other test files. However [serialize_tests.cpp](https://github.com/bitcoin/bitcoin/blob/v0.15.0rc3/src/test/serialize_tests.cpp#L245) also uses `BOOST_CHECK_EXCEPTION` and it defines the predicate in the test file itself.
Instead of four `IsRejectInvalidReasonX(std::runtime_error const& e)` functions, I'd prefer something reusable like `bool IsRejectInvalidReason(String reason)(std::runtime_error const& e)`, which would be used like `BOOST_CHECK_EXCEPTION(functionThatThrows(), std::runtime_error, IsRejectInvalidReason("bad-blk-sigops")`. I couldn't figure out how to do that in C++.

2dd6f80 Add a test that all flags are softforks (Pieter Wuille)
2851b77 Make all script verification flags softforks (Pieter Wuille)
Pull request description:
This change makes `SCRIPT_VERIFY_UPGRADABLE_NOPS` not apply to `OP_CHECKLOCKTIMEVERIFY` and `OP_CHECKSEQUENCEVERIFY`. This is a no-op as `UPGRADABLE_NOPS` is only set for mempool transactions, and those always have `SCRIPT_VERIFY_CHECKLOCKTIMEVERIFY` and `SCRIPT_VERIFY_CHECKSEQUENCEVERIFY` set as well. The advantage is that setting more flags now always results in a reduction in acceptable scripts (=softfork).
This results in a nice and testable property for validation, for which a new test is added.
This also means that the introduction of a new definition for a NOP or witness version will likely need the following procedure (example OP_NOP8 here)
* Remove OP_NOP8 from being affected by `SCRIPT_VERIFY_DISCOURAGE_UPGRADABLE_NOPS`.
* Add a `SCRIPT_VERIFY_DISCOURAGE_NOP8`, which only applies to `OP_NOP8`.
* Add a `SCRIPT_VERIFY_NOP8` which implements the new consensus logic.
* Before activation, add `SCRIPT_VERIFY_DISCOURAGE_NOP8` to the mempool flags.
* After activation, add `SCRIPT_VERIFY_NOP8` to both the mempool and consensus flags.

blockchain.cpp has low unit test coverage. This commit is intended
to start improving its code coverage to reasonable levels. One or more
follow up commits will complete the task that this commit is starting
(though the usefulness of this commit is not dependent upon later
commits).
Note that these tests were not written based upon a specification of how
GetDifficulty *should* work, but rather how it actually *does* work. As
a result, if there are any bugs in the current GetDifficulty
implementation, these unit tests serve to lock them in rather than
expose them.
-- Why has blockchain.cpp been modified if this is a unit testing change?
Since the existing GetDifficulty function relies on a global variable,
chainActive, it was not suitable for unit testing purposes. Both the
existing GetDifficulty function and the unit tests now call through to
a new, more modular version of GetDifficulty that can work on any chain,
not just chainActive.
-- Why does blockchain_tests.cpp directly include blockchain.cpp instead
of blockchain.h?
While the new GetDifficulty function's signature is arguably better than
the old one's, it still isn't great, and doesn't seem to warrant inclusion
as part of the blockchain.h API, especially since only test code is
directly using it. If a better way of exposing the new GetDifficulty
function to unit tests exists, please mention it and the commit will be
updated accordingly.
-- Why is the test fixture named blockchain_difficulty_tests rather than
blockchain_tests?
The Bitcoin Core policy for naming unit test files is to match the the
file under test ("blockchain" becomes "blockchain_tests"). While this
commit complies with that, blockchain.cpp is a massive file, such that
having all of the unit tests in one file will tend towards disorder.
Since there will be a lot more tests added to this file, the intention
is to divide up different types of tests into different test fixtures
within the same file.
BOOST_CHECK_THROW merely checks that some std::runtime_error is
thrown, but not which one.
One example of how this could lead to a test passing when a developer
introduces a consensus bug: the test for the sigops limit assumes
that CreateNewBlock fails with bad-blk-sigops. However it can
also fail with bad-txns-vout-negative, e.g. if a naive developer lowers
BLOCKSUBSIDY to 1*COIN in the test.
BOOST_CHECK_EXCEPTION allows an additional predicate function. This
commit uses this for all exceptions that are checked for in
miner_tets.cpp:
* bad-blk-sigops
* bad-cb-multiple
* bad-txns-inputs-missingorspent
* block-validation-failed
An instance of the CheckRejectInvalid class (for a given validation string)
is passed to BOOST_CHECK_EXCEPTION.

Pull request description:
Most tests shouldn't have to deal with the now-historical SegWit activation transition (and other deployments, but SegWit is certainly the hardest one to accomodate).
This PR makes a versionbits starttime of -1 equal to "always active", and enables it by default for SegWit on regtest. Individual tests can override this by using the existing `-vbparams` option.
A few unit tests and functional tests are adapted to indeed override vbparams, as they specifically test the transition.
This is in preparation for wallet SegWit support, but I thought having earlier eyes on it would be useful.

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).

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...

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.
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

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.

`make` rebuilds the entire project. This is quite slow if e.g. you're making changes to one file and only wish to run the bitcoind tests.
This commit adds an instruction to run `make -C src/test` (as opposed to `make src/test` and `make src/test/test_bitcoin`).
In this test, `nTime` is used for all the calls to `Mine()`, each time being set to the correct time beforehand, except for in the last few calls to `Mine()` where `nStartTime` is used directly, even though `nTime` is still set to `nStartTime` beforehand. `nTime` just remains unused for these last few calls to `Mine()`.
Changed the last few calls to `Mine()` to use `nTime` instead, improving consistency. This also fixes an unused value static analyzer warning about `nTime` being set to a value which is never used.

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:

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)

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 +

* 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.

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.

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:
bitcoin-cli's `-rpcconnect` can accept ipv6 addresses (as long as the libevent version is new enough), but fails to parse ipv6 with square brackets. This PR makes `bitcoin-cli` parse ipv6 in square brackets correctly.
`bitcoin-cli -rpcconnect=[::1] <command>`
should now be equivalent to
`bitcoin-cli -rpcconnect=::1 <command>`
This is useful so the `bitcoin-cli` option can now be in the same format as the `bitcoind` option.
Doesn't include tests. I have a branch that fully tests `bitcoin-cli`, but that's queued behind several intermediate PRs.
- first commit moves `SplitHostPort()` from libbitcoin_common into libbitcoin_util
- second commit adds proper ipv6 parsing to bitcoin-cli

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.
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.
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.

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.
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.
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.

Removed duplicate words such as "the the".
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).

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.
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.
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 earlier CTxInUndo class now holds the same information as the Coin
class. Instead of duplicating functionality, replace CTxInUndo with a
serialization adapter for Coin.
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.
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).

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.. )
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.
