... unless they're UNCONDITIONAL_RELAY_DELAY old, or there has been
a response to a MEMPOOL request in the mean time.
This is accomplished using a rolling Bloom filter for the last
3500 announced transactions. The probability of seeing more than 100
broadcast events (which can be up to 35 txids each) in 2 minutes for
an outbound peer (where the average frequency is one per minute), is
less than 1 in a million.
This constant is set to 2 minutes, rather than 15. This is still many times
larger than the transaction broadcast interval (2s for outbound, 5s for
inbound), so it should be acceptable for peers to know what our contents of
the mempool was that long ago.

This patch improves performance and resource usage around IP addresses that are banned for misbehavior. They're already not actually banned since #14929, as connections from them are still allowed, but they are preferred for eviction if the inbound connection slots are full.
Stop treating these like manually banned IP ranges, and instead just keep them in a rolling Bloom filter of misbehaving nodes, which isn't persisted to disk or exposed through the ban framework. The effect remains the same: preferred for eviction, avoided for outgoing connections, and not relayed to other peers.

Pull request description:
This is another intermediate part of the Coinstats Index (tracked in #18000).
Sjors suggested [here](https://github.com/bitcoin/bitcoin/pull/18000#issuecomment-641423019) that the part of the changes in #19145 that don't rely on the new `hash_type` muhash, i.e. that are for `hash_type=none`, could be merged separately from everything involving muhash. So these changes are extracted from #19145 here and can be merged without any other requirements.
Building the index with no UTXO set hash is still valuable because `gettxoutsetinfo` can still be used to audit the `total_amount` for example. By itself this PR is not a huge improvement, `hash_type=none` is speeding up `gettxoutsetinfo` by about 10%, but it enables the implementation of an index on top of it in a follow-up and that means large parts of the index code of Coinstats Index can be merged while reviews for the hashing algorithm might take longer.

Pull request description:
The `BerkeleyBatch` class has 4 static functions that operate on `BerkeleyDatabase` or `BerkeleyEnvironment`. It doesn't make sense for these to be standalone nor for them to be static functions. So instead, move them from `BerkeleyBatch` into `BerkeleyDatabase` and make them member functions instead of static.
`BerkeleyBatch::VerifyEnvironment` and `BerkeleyBatch::VerifyDatabaseFile` are combined into a single `BerkeleyDatabase::Verify` function that operates on that `BerkeleyDatabase` object.
`BerkeleyBatch::Rewrite` and `BerkeleyBatch::PeriodicFlush` both took a `BerkeleyDatabase` as an argument and did stuff on it. So we just make it a member function so it doesn't need to take a database as an argument.

961e667600441c35845fcb36b120500c813cd3ed Remove cached directories and associated script blocks from appveyor CI configuration. (Aaron Clauson)
Pull request description:
Appveyor CI jobs have been failing in the last 24 hours due to a seemingly corrupted cache, see #19440.
It's possible that the appveyor cache issue is related to the[ recent update](https://www.appveyor.com/updates/2020/07/03/) of the Visual Studio 2019 image
PR #19431 changes the "save cache or error" to false in an attempt to avoid a failing CI job from potentially corrupting the cache. In theory the only way a PR could affect the cache is if the `vcpkg` install list changed. That happens very rarely and did not happen in the last 24 hours and so was not the cause of the current cache problems.
I have done some testing with appveyor build jobs on my own fork and found that installing the `vcpkg` dependencies from scratch and doing a full build can now be done in just under 60 minutes. This is the first time in over 5 months I have been able to build Bitcoin Core on appveyor. Either the new Visual Studio 2019 image has dramatically reduced the build time or appveyor images have had their CPU increased.
This PR removes all use of dependency caching from the appveyor CI config. The trade-off is the 15 minutes saved on each build from having the dependencies cached versus the hours maintainers need to spend investigating when the CI jobs start failing.

Contains release notes and several interface improvements by
John Newbery.
When loading descriptor caches, we would accidentally reinitialize the
descriptor cache when seeing that one already exists. This should have
only been initializing the cache when one does not exist. However this
code itself is unnecessary as the act of looking up the cache to add to
it will initialize it if it didn't already exist.
This issue could be hit by trying to load a wallet that had imported a
multisig descriptor. The wallet would fail to load.
A test has been added to wallet_importdescriptors.py to catch this case.
Another test case has also been added to check that loading a wallet
with only single key descriptors works.
fa8e6df282af0d396d75b03721f1b59a520ced19 ci: Run tsan ci config on cirrus (MarcoFalke)
Pull request description:
Fixes bitcoin-core/gui#12
Copied description from #19321:
Currently it is not possible to use travis in forked repositories due to the 50 minute limit on builds. A fresh build (uncached) of the thread sanitizer config takes more than 50 minutes.
One approach to fix this could be to throw away tests until the run time is less than 50 minutes. However, the risk of being blind of failures in the thrown away tests is not worth the gain. Also, to detect them, one has to run the tsan configuration nightly and failures could only be detected post-merge.
Another approach would be to ask travis support to raise the limit for a forked repository. This is a tedious and manual one-by-one process, so I'd rather not.
Finally, a different ci provider can be used, since the config files are designed to be platform-agnostic. This is what I picked.
I kept all settings identical to the travis machine for now. Both providers run in the google cloud, so this should be a "move-only".

fa0dfdf447d5b84a1849dc823d8508463600136a refactor: Remove confusing BlockIndex global (MarcoFalke)
Pull request description:
The global `::BlockIndex()` is problematic for several reasons:
* It returns a mutable reference to the block tree, without the appropriate lock annotation (`m_block_index` is guarded by `cs_main`). The current code is fine, but in the future this might lead to accidental races and data corruption.
* The rpc server shouldn't rely on node globals, but rather a context that is passed in to the RPC method.
* Tests might want to spin up their own block tree, and thus should also not rely on a single global.
Fix all issues by removing the global

a8d39b88406e2047746366355666b5f603105a2e doc: explain why passing -mlinker-version is required (fanquake)
Pull request description:
I have been down a 🐇 hole. Closes#19359.
When Clang is compiled, [a check is run](https://github.com/llvm/llvm-project/blob/release/8.x/clang/CMakeLists.txt#L353) to define `HOST_LINK_VERSION` as the output of `$CMAKE_LINKER -v`. Note the this is the version of the linker being used to compile Clang itself.. and this check is only run when compiling Clang for macOS.
In the Clang driver, if `HOST_LINK_VERSION` has been defined, there is some additional runtime functionality. An `-mlinker-version` argument, with the value of `HOST_LINK_VERSION` [will be added to the linker arguments](89de0d8dfb/clang/lib/Driver/Driver.cpp (L382)), if `-mlinker-version` has not been passed in by the user.
This is a bit weird, as by default, you are setting `-mlinker-version` to the version of the linker that was used to build the Clang binary, not the linker which will be used when compiling. The commit which introduced the functionality, 628fcf4e3b, described it as a "hack", that should be replaced. However, that was 10 years ago, and the behaviour is still here.
In the Darwin driver, [a check is done](89de0d8dfb/clang/lib/Driver/ToolChains/Darwin.cpp (L208)) for the `-mlinker-version` argument. If there is no argument, the version will default to `0`. Given the above, this should never happen when using Clang for macOS. A series of comparisons are then performed, to check whether the linker version is modern enough to enable certain features, like [`-demangle`](89de0d8dfb/clang/lib/Driver/ToolChains/Darwin.cpp (L215)).
### What this means
#### macOS
A Clang compiled for macOS, i.e `clang+llvm-8.0.0-x86_64-apple-darwin`, will have `HOST_LINKER_VERSION` set to the version of the linker used to compile Clang itself.
At runtime, `-mlinker-version=HOST_LINKER_VERSION` will be added to the linker args, if `-mlinker-version` wasn't passed in. In the Darwin driver, additional arguments, like `-demangle`, will be added to the linker arguments, because `HOST_LINKER_VERSION` was likely some very modern version of `lld` or `ld64`.
#### Linux (cross compilation in depends)
A Clang compiled for Linux, i.e `clang+llvm-8.0.0-x86_64-linux-gnu-ubuntu-14.04`, which we now use for macOS builds in depends, will behave differently. As it's built for Linux, `HOST_LINKER_VERSION` was not defined at compile time, and there will be no default behaviour of appending `-mlinker-version=HOST_LINKER_VERSION` to the linker args. Thus, unless you pass in `-mlinker-version` yourself, when the version checks are done in the Darwin driver, no modern linker features will be enabled, as the version will have defaulted to `0`.
Therefore, it's important that we continue to pass `-mlinker-version="our LD64 version"` as part of our compilation flags, if we want to have "modern" linker features enabled for our macOS builds.
#### Summary
[Clang 8](https://releases.llvm.org/download.html#8.0.0). Building a macOS binary. Link line with path arguments trimmed.
| | default behaviour | `-mlinker-version=100` (`-demangle threshold`) | `-mlinker-version=530` |
| - | --------------- | --------------------- | ---------------------- |
| macOS Clang | `-demangle -lto_library ../libLTO.dylib -no_deduplicate -dynamic -arch x86_64 -macosx_version_min 10.15.0 -o a.out ../test-b8b9b3.o -lc++ -lSystem ../libclang_rt.osx.a` | `-demangle -dynamic -arch x86_64 -macosx_version_min 10.15.0 -o a.out ../test-a66966.o -lc++ -lSystem ../libclang_rt.osx.a` | same as default |
| Linux Clang | `-dynamic -arch x86_64 -macosx_version_min 10.12.0 -o a.out ../test-bfce57.o -lc++ -lSystem` | `-demangle -dynamic -arch x86_64 -macosx_version_min 10.12.0 -o a.out ../test-a846a3.o -lc++ -lSystem` | `-demangle -lto_library ../libLTO.dylib -no_deduplicate -dynamic -arch x86_64 -macosx_version_min 10.12.0 -o a.out ../test-de0280.o -lc++ -lSystem` |
Note: Most links here are pointing to the 8.x branch of LLVM/Clang, as we are using that version in depends.
Note: To add a little more confusion, you wont see `-mlinker-version X` in your compile flags, you'll see [`-target-linker-version X`](431daedee4/clang/lib/Driver/ToolChains/Clang.cpp (L4777)).

Add `std::locale::global` to list of locale dependent functions in `lint-locale-dependence.sh`.
We currently flag `setlocale(...)` as locale dependent, but prior to this commit we didn't flag
`std::locale::global(...)` as such.
In addition to setting the global C++ locale `std::locale::global(...)` also does the equivalent of `std::setlocale(LC_ALL, ...);`.
Thus the functionality of `std::locale::global(...)` is a superset of `setlocale(...)` :)

Pull request description:
Due to recent changes to hardware wallets, the full previous transaction will need to be provided for segwit inputs. Since some software may be checking for the existence of a `witness_utxo` to determine whether to produce a segwit signature, we keep that field to ease the transition.
Because all of the sanity checks implemented by the `IsSane` functions were related to having mixed segwit and non-segwit data in a PSBT, those functions are removed as those checks are no longer proper.
Some tests are updated/removed to accommodate this and a simple test added to check that both UTXOs are being added to segwit inputs.
As discussed in the wallet IRC meeting, our own signer will not require `non_witness_utxo` for segwit inputs.

utACK 84d295e51341a126a6c3cbeea7a8caa04c7b5bc3 (didn't retest compared to 836d6fc, but fortunately HWI's CI tracks our master branch, with a bunch of hardware wallet simulators)

Code review re-ACK 84d295e51341a126a6c3cbeea7a8caa04c7b5bc3. No changes since last review, but now I understand the context better. I think it would good to improve the comments as suggested https://github.com/bitcoin/bitcoin/pull/19215#discussion_r447889473 and maybe refer to

Pull request description:
Add MemorySanitizer (MSan) in Travis to detect use of uninitialized memory.
First UBSan, then ASan followed by TSan... and now: yes, the wait is over -- **MSan is finally here!** :)
Some historical context:
* 2017: Continuous compilation with Clang Thread Safety analysis enabled (#10866, #10923)
* 2018: Continuous testing with trapping on signed integer overflows (`-ftrapv`) (#12686)
* 2018: Continuous testing of use of locale dependent functions (#13041)
* 2018: Continuous testing of format strings (#13705)
* 2018: Continuous compilation with MSVC `TreatWarningAsError` (#14151)
* 2018: Continuous testing under UndefinedBehaviorSanitizer – UBSan (#14252, #14673, #17006)
* 2018: Continuous testing under AddressSanitizer – ASan (#14794, #17205, #17674)
* 2018: Continuous testing under ThreadSanitizer – TSan (#14829)
* 2019: Continuous testing in an unsigned char environment (`-funsigned-char`) (#15134)
* 2019: Continuous compile-time testing of assumptions we're making (#15391)
* 2019: Continuous testing of fuzz test cases under Valgrind (#17633, #18159, #18166)
* 2020: Finally... MemorySanitizer – MSAN! :)
What is the next step? What tools should we add to CI to keep bugs from entering `master`? :)
