e60ef21b8a doc: Clang 8 or later is required with FORCE_USE_SYSTEM_CLANG (fanquake)
Pull request description:
The usage of pragmas within the macOS SDK requires LLVM Clang 8. This is
the same version as our prebuilt Clang, however the minimum is worth noting
here as they may diverge and/or expert users might expect they could use an
earlier version.
If you compile depends using `FORCE_USE_SYSTEM_CLANG=1` and Clang 7 you'll see output like:
```bash

I've got a [godbolt here](https://godbolt.org/z/j6r987) that contains a demo of the issue (based off the macOS SDK). It will compile with Clang 8 but not with Clang 7.

0103d6434e Introduce DummyDatabase and use it in the tests (Andrew Chow)
Pull request description:
In the unit tests, we use a dummy `WalletDatabase` which does nothing and always returns true. This is currently implemented by creating a `BerkeleyDatabase` in dummy mode. This PR instead adds a `DummyDatabase` class which does nothing and never fails for use in the tests. `CreateDummyWalletDatabase` is changed to return this `DummyDatabase` and `BerkeleyDatabase` is cleaned up to remove all of the checks for `IsDummy`.

4254cd9f8f p2p: add CInv transaction message helper methods (Jon Atack)
Pull request description:
Following the merge of wtxid relay in #18044, this is the first of three refactoring PRs (this one, #19610, and #19611) with no change in behavior, tightly scoped to ease review, to simplify the net processing code and improve encapsulation:
- add `CInv` transaction message helper methods, defined in the class
- use the new helpers in `net_processing.cpp` to simplify the code and improve encapsulation
Test coverage is provided by the functional p2p tests, notably (from seeing which tests failed when breaking things to test coverage) `p2p_segwit`, `p2p_tx_download`, `p2p_feefilter`, and `p2p_permissions`.

78c312c983 Replace current benchmarking framework with nanobench (Martin Ankerl)
Pull request description:
Replace current benchmarking framework with nanobench
This replaces the current benchmarking framework with nanobench [1], an
MIT licensed single-header benchmarking library, of which I am the
autor. This has in my opinion several advantages, especially on Linux:
* fast: Running all benchmarks takes ~6 seconds instead of 4m13s on
an Intel i7-8700 CPU @ 3.20GHz.
* accurate: I ran e.g. the benchmark for SipHash_32b 10 times and
calculate standard deviation / mean = coefficient of variation:
* 0.57% CV for old benchmarking framework
* 0.20% CV for nanobench
So the benchmark results with nanobench seem to vary less than with
the old framework.
* It automatically determines runtime based on clock precision, no need
to specify number of evaluations.
* measure instructions, cycles, branches, instructions per cycle,
branch misses (only Linux, when performance counters are available)
* output in markdown table format.
* Warn about unstable environment (frequency scaling, turbo, ...)
* For better profiling, it is possible to set the environment variable
NANOBENCH_ENDLESS to force endless running of a particular benchmark
without the need to recompile. This makes it to e.g. run "perf top"
and look at hotspots.

82dee87933 test: test decodepsbt fee calculation (count input value only once per UTXO) (Sebastian Falbesoner)
Pull request description:
Fixes#19523, adding a simple test to `rpc_psbt.py` that checks that the decodepsbt fee matches the one given by the wallet (`walletcreatefundedpsbt`). This is in particular important for PSBTs with segwit inputs that have both a witness- and a non-witness-UTXO type set.
Example test run after reverting commit 75122780e2 ("Increment input value sum only once per UTXO in decodepsbt"):

2c6a02e024 Clean message_count and last_message (Troy Giorshev)
Pull request description:
From #19580
This PR changes comments to clarify the intended usage of `message_count` and `last_message`. Additionally it changes the only usage of `message_count` to use `last_message` instead, bringing the code into alignment with the intended usage.
Note: Now `message_count` is completely unused. However, it is ready to be used (i.e. the supporting code works) and likely will be used in some test in the future.

Previously having no database handle could still be considered a success
when BerkeleyDatabase and BerkeleyBatch were used for dummy database
things. With dedicated DummyDatabase and DummyBatch classes now, these
should fail.

65fb8807ac Combine BerkeleyEnvironment::Verify into BerkeleyDatabase::Verify (Andrew Chow)
Pull request description:
`BerkeleyBatch` and `BerkeleyDatabase` are kind of messy. The goal of this is to clean up them up so that they are logically separated.
`BerkeleyBatch` currently handles the creation of the `BerkeleyDatabase`'s `Db` handle. This is instead moved into `BerkeleyDatabase` and is called by `BerkeleyBatch`.
Instead of having `BerkeleyEnvironment` track each database's usage, have `BerkeleyDatabase` track this usage itself with the `m_refcount` variable that is present in `WalletDatabase`.
Lastly, instead of having each `BerkeleyEnvironment` store the fileids of the databases open in it, have a global `g_fileids` to track those fileids. We were already checking fileid uniqueness globally (by checking the fileids in every environment when opening a database) so it's cleaner to do this with a global variable.
All of these changes allow us to make `BerkeleyBatch` and `BerkeleyDatabase` no longer be friend classes.

65d0f1a533 devtools: Add security check for separate_code (Wladimir J. van der Laan)
2e9e6377f1 build: add -Wl,-z,separate-code to hardening flags (fanquake)
Pull request description:
TLDR: We are generally explicit about the hardening related flags we use,
rather than letting the distro / toolchain decide via their defaults. This PR
adds `-z,separate-code` which has been enabled by default for Linux targets
since binutils 2.31. Ubuntu Bionic (currently used for gitian) ships with
binutils 2.30, so this will enable the option for those builds.
This flag was added to binutils/ld in the 2.30 release,
see commit c11c786f0b45617bb8807ab6a57220d5ff50e414:
> The new "-z separate-code" option will generate separate code LOAD
segment which must be in wholly disjoint pages from any other data.
It was made the default for Linux/x86 targets in the 2.31 release, see commit
f6aec96dce1ddbd8961a3aa8a2925db2021719bb:
> This patch adds --enable-separate-code to ld configure to turn on
-z separate-code by default and enables it by default for Linux/x86.
This avoids mixing code pages with data to improve cache performance
as well as security.
> To reduce x86-64 executable and shared object sizes, the maximum page
size is reduced from 2MB to 4KB when -z separate-code is turned on by
default. Note: -z max-page-size= can be used to set the maximum page
size.
> We compared SPEC CPU 2017 performance before and after this change on
Skylake server. There are no any significant performance changes.
Everything is mostly below +/-1%.
Support was also added to LLVMs lld: https://reviews.llvm.org/D64903, however
there it remains off by default.
There were concerns about an increase in binary size, however in our case, the
difference would seem negligible, given we are shipping a
multi-megabyte binary, which then downloads 100's of GBs of data.
Also note that most recent versions of distros are shipping a new enough version
of binutils that this is available and/or already on by default (assuming the distro
has not turned it off, I haven't checked everywhere):

bcfebb6d55 net: save the network type explicitly in CNetAddr (Vasil Dimov)
100c64a95b net: document `enum Network` (Vasil Dimov)
Pull request description:
(chopped off from https://github.com/bitcoin/bitcoin/pull/19031 to ease review)
Before this change, we would analyze the contents of `CNetAddr::ip[16]`
in order to tell which type is an address. Change this by introducing a
new member `CNetAddr::m_net` that explicitly tells the type of the
address.
This is necessary because in BIP155 we will not be able to tell the
address type by just looking at its raw representation (e.g. both TORv3
and I2P are "seemingly random" 32 bytes).
As a side effect of this change we no longer need to store IPv4
addresses encoded as IPv6 addresses - we can store them in proper 4
bytes (will be done in a separate commit). Also the code gets
somewhat simplified - instead of
`memcmp(ip, pchIPv4, sizeof(pchIPv4)) == 0` we can use
`m_net == NET_IPV4`.

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
---
In the assumeutxo implementation draft (#15056), once a UTXO snapshot is loaded, a new chainstate object is created after initialization. This means that we have to reclaim some of the cache that we've allocated to the original chainstate (per `dbcache=`) to repurpose for the snapshot chainstate.
Furthermore, it makes sense to have different cache allocations depending on which chainstate is more active. While the snapshot chainstate is working to get to the network tip (and the background validation chainstate is idle), it makes sense that the snapshot chainstate should have the majority of cache allocation. And contrariwise once the snapshot has reached network tip, most of the cache should be given to the background validation chainstate.
This set of changes (detailed in the commit messages) allows us to dynamically resize the various coins caches. None of the functionality introduced here is used at the moment, but will be in the next AU PR (which introduces `ActivateSnapshot`).
`ChainstateManager::MaybeRebalanceCaches()` defines the (somewhat normative) cache allocations between the snapshot and background validation chainstates. I'd be interested in feedback if anyone has thoughts on the proportions I've set there.

The usage of pragmas within the macOS SDK requires LLVM Clang 8. This is
the version as our prebuilt Clang, however the minimum is worth noting here
as they may diverge and/or expert users might expect they could use an
earlier version.
If you compile using Clang 7 you'll see output like:

Pull request description:
This didn't work for a few reasons (various toolchain compatibility issues) the last time I tested it, but after the last round of bumps it works with no apparent issues.
Note that this does not _enable_ LTO by default in any way, only hooks up the machinery for ```-flto``` to work correctly when specified.
Lines were split for an easier rebase after #17919 is merged.

fa5979d12f rpc: Avoid useless mempool query in gettxoutproof (MarcoFalke)
fa1f7f28cb rpc: Style fixups in gettxoutproof (MarcoFalke)
Pull request description:
`GetTransaction` implicitly and unconditionally asks the mempool global for a transaction. This is problematic for several reasons:
* `gettxoutproof` is for on-chain txs only and asking the mempool for on-chain txs is confusing and minimally wasteful
* Globals are confusing and make code harder to test with unit tests
Fix both issues by passing in an optional mempool. This also helps with #19556

This flag was added to binutils/ld in the 2.30 release,
see commit c11c786f0b45617bb8807ab6a57220d5ff50e414:
> The new "-z separate-code" option will generate separate code LOAD
segment which must be in wholly disjoint pages from any other data.
It was made the default for Linux/x86 targets in the 2.31 release, see commit
f6aec96dce1ddbd8961a3aa8a2925db2021719bb:
> This patch adds --enable-separate-code to ld configure to turn on
-z separate-code by default and enables it by default for Linux/x86.
This avoids mixing code pages with data to improve cache performance
as well as security.
> To reduce x86-64 executable and shared object sizes, the maximum page
size is reduced from 2MB to 4KB when -z separate-code is turned on by
default. Note: -z max-page-size= can be used to set the maximum page
size.
> We compared SPEC CPU 2017 performance before and after this change on
Skylake server. There are no any significant performance changes.
Everything is mostly below +/-1%.
Support was also added to LLVMs lld: https://reviews.llvm.org/D64903, however
there is remains off by default.
There were concerns about an increase in binary size, however in our case, the
increase (1 page worth of bytes) would seem negligible, given we are shipping a
multi-megabyte binary, which then downloads 100's of GBs of data.
Also note that most recent versions of distros are shipping a new enough version
of binutils that this is available and/or on by default (assuming the distro has
not turned it off, I haven't checked everywhere):

Before this change, we would analyze the contents of `CNetAddr::ip[16]`
in order to tell which type is an address. Change this by introducing a
new member `CNetAddr::m_net` that explicitly tells the type of the
address.
This is necessary because in BIP155 we will not be able to tell the
address type by just looking at its raw representation (e.g. both TORv3
and I2P are "seemingly random" 32 bytes).
As a side effect of this change we no longer need to store IPv4
addresses encoded as IPv6 addresses - we can store them in proper 4
bytes (will be done in a separate commit). Also the code gets
somewhat simplified - instead of
`memcmp(ip, pchIPv4, sizeof(pchIPv4)) == 0` we can use
`m_net == NET_IPV4`.

While this is not undefined behaviour, the memory aliasing trick is confusing when reading the code. Having `a.size()==0` and then access `a[0]` works in this particular case, but should probably be avoided to harden the code for the future.

Checks that the RPC decodepsbt calculates the fee correctly, in particular for
PSBTs with segwit inputs that have both a witness- and a non-witness-UTXO type
set. Before commit 75122780e2 ("Increment input
value sum only once per UTXO in decodepsbt") the values for those inputs were
double counted.
- Make const things const.
- Replace conditional return with assert.
- Don't log the peer's IP address.
- Log the name Misbehaving directly instead of relying on __func__.
Misbehaving() could optionally take a debug string for printing to the
log file. Make this mandatory and always provide the string.
A couple of additional minor changes:
- remove the unnecessary forward declaration of Misbehaving()
- don't include the nodeid or newline in the passed debug message.
Misbehaving() adds these itself.
