b17e91d842 refactoring: introduce CChainState::GetCoinsCacheSizeState (James O'Beirne)
Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
This pulls out the routine for detection of how full the coins cache is from
FlushStateToDisk. We use this logic independently when deciding when to flush
the coins cache during UTXO snapshot activation ([see here](231fb5f17e (diff-24efdb00bfbe56b140fb006b562cc70bR5275))).

Instead of using /16 netgroups to bucket nodes in Addrman for connection
diversification, ASN, which better represents an actor in terms
of network-layer infrastructure, is used.
For testing, asmap.raw is used. It represents a minimal
asmap needed for testing purposes.

Pull request description:
Now that #17165 has been merged, removing our remaining OpenSSL usage is possible.
That remaining usage was a call to [`RAND_bytes`](https://www.openssl.org/docs/manmaster/man3/RAND_bytes.html) during the ::SLOW path of [ProcRand](https://github.com/bitcoin/bitcoin/blob/master/src/random.cpp#L616). As well as feeding output from our RNG back into OpenSSL via [`RAND_add`](https://www.openssl.org/docs/manmaster/man3/RAND_add.html) during the ::SLOW and ::SLEEP paths.
Optimistically tagged for `0.20.0`. Needs discussion, potentially in an upcoming weekly meeting?
Closes#12530.

dcef9a2922 logs: add timing information to FlushStateToDisk() (James O'Beirne)
41edaf227a logs: add BCLog::Timer and related macros (James O'Beirne)
Pull request description:
It's currently annoying to detect FlushStateToDisk() calls when benchmarking since they have to be inferred from a drop in coins count from the `UpdateTip: ` log messages. This adds a new logging utility, `BCLog::Timer`, and some related macros that are generally useful for printing timing-related logging messages, and a message that is unconditionally written when the coins cache is flushed to disk.

Pull request description:
This introduces a new BlockFilterIndex class, which is required for BIP 157 support.
The index is uses the asynchronous BaseIndex infrastructure driven by the ValidationInterface callbacks. Filters are stored sequentially in flat files and the disk location of each filter is indexed in LevelDB along with the filter hash and header. The index is designed to ensure persistence of filters reorganized out of the main chain to simplify the BIP 157 net implementation.
Stats (block height = 565500):
- Syncing the index from scratch takes 45m
- Total index size is 3.8 GiB

Link against BasicTestingSetup in the fuzz tests, so we can fuzz against validation.
Also include a commit to remove test_bitcoin_main.cpp. That file may or may not overwrite globals in the link stage depending on the link order. This is confusing and useless anyway: The unit tests should never `std::exit` in the middle of the run (especially with success as exit code), since it will skip all test modules afterward.
Also include a commit to remove some unused forward declarations and move the main_tests to validation_tests, since main was long ago split into net_processing and validation.

f1f4bb7345 Free BerkeleyEnvironment instances when not in use (Russell Yanofsky)
Pull request description:
Instead of adding BerkeleyEnvironment objects permanently to the g_dbenvs map, use reference counted shared pointers and remove map entries when the last BerkeleyEnvironment reference goes out of scope.
This change was requested by @TheBlueMatt and makes code that sets up mock databases cleaner. The mock database environment will now go out of scope and be reset on destruction so there is no need to call BerkeleyEnvironment::Reset() during wallet construction to clear out prior state.
This change does affect bitcoin behavior slightly. On startup, instead of same wallet environments staying open throughout VerifyWallets() and OpenWallets() calls, VerifyWallets() will open and close an environment once for each wallet, and OpenWallets() will create its own environment(s) later.

41c607f09b Implement PSBT Structures and un/serialization methods per BIP 174 (Andrew Chow)
Pull request description:
This Pull Request fully implements the [updated](https://github.com/bitcoin/bips/pull/694) BIP 174 specification. It is based upon #13425 which implements the majority of the signing logic.
BIP 174 specifies a binary transaction format which contains the information necessary for a signer to produce signatures for the transaction and holds the signatures for an input while the input does not have a complete set of signatures.
This PR contains structs for PSBT, serialization, and deserialzation code. Some changes to `SignatureData` have been made to support detection of UTXO type and storing public keys.
***
Many RPCs have been added to handle PSBTs.
`walletprocesspsbt` takes a PSBT format transaction, updates the PSBT with any inputs related to this wallet, signs, and finalizes the transaction. There is also an option to not sign and just update.
`walletcreatefundedpsbt` creates a PSBT from user provided data in the same form as createrawtransaction. It also funds the transaction and takes an options argument in the same form as `fundrawtransaction`. The resulting PSBT is blank with no input or output data filled in. It is analogous to a combination of `createrawtransaction` and `fundrawtransaction`
`decodepsbt` takes a PSBT and decodes it to JSON. It is analogous to `decoderawtransaction`
`combinepsbt` takes multiple PSBTs for the same tx and combines them. It is analogous to `combinerawtransaction`
`finalizepsbt` takes a PSBT and finalizes the inputs. If all inputs are final, it extracts the network serialized transaction and returns that instead of a PSBT unless instructed otherwise.
`createpsbt` is like `createrawtransaction` but for PSBTs instead of raw transactions.
`convertpsbt` takes a network serialized transaction and converts it into a psbt. The resulting psbt will lose all signature data and an explicit flag must be set to allow transactions with signature data to be converted.
***
This supersedes #12136

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.

66f3255 tests: split up actual tests and helper files (Cory Fields)
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.

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.

Pull request description:
Currently `./configure && make check` will look for python3, then python2. As long as we support python2 (and use it as fallback), `make check` should run fine with both python2 and python3.

Pull request description:
What started as a simple task to add test coverage ended up giving way to a light refactoring. This consolidates the mostly-identical `CMerkleBlock` constructors into one (using C++11 constructor delegation) and adds coverage for the by-txids construction case.

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`.
