fa0540cd46eaf44d9e1a9f91c3a937986826c4fa net: Extract download permission from noban (MarcoFalke) Pull request description: It should be possible to grant nodes in a local network (e.g. home, university, enterprise, ...) permission to download blocks even after the maxuploadtarget is hit. Currently this is only possible by setting the `noban` permission, which has some adverse effects, especially if the peers can't be fully trusted. Fix this by extracting a `download` permission from `noban`.

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. Also change the name of this mechanism to "discouraged" to better reflect reality.

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.

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.

from appveyor config 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.

2020-07-03Replace automatic bans with discouragement filterPieter Wuille
This patch improves performance and resource usage around IP addresses that are banned for misbehavior. They're already not actually banned, 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. Also change the name of this mechanism to better reflect reality; they're not banned, just discouraged. Contains release notes and several interface improvements by John Newbery.

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".

cross-compiling 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](https://github.com/llvm/llvm-project/blob/89de0d8dfbb9a6ff1f8b141ed70b563ecc094878/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, https://github.com/llvm/llvm-project/commit/628fcf4e3b79ba9f41dd1b49b1aba7a20b68fc0e, 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](https://github.com/llvm/llvm-project/blob/89de0d8dfbb9a6ff1f8b141ed70b563ecc094878/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`](https://github.com/llvm/llvm-project/blob/89de0d8dfbb9a6ff1f8b141ed70b563ecc094878/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.

Simply allowing that option makes the code confusing and review harder than it needs to be. * To make review even harder, `CHANGE_AUTO` requires `-Wswitch` to be disabled for `OutputType` Fix both issues by removing `CHANGE_AUTO` and then enabling `-Wswitch` for `OutputType` ACKs for top commit: promag: Code review ACK fa927ff884ae373c676deed63180a8d238872cdc. laanwj: Code review ACK fa927ff884ae373c676deed63180a8d238872cdc Tree-SHA512: 24fd809757aa343866c94dafe9a7130b50cda4f77c97666d407f99b813f75b115a7d8e688a6bc2a737e87cba64ddd4e43f2b3c5538fd35fabb5845807bb39134

I know that C++17 is not "officially" supported yet, especially not with all boost versions, since C++17 is meant to replace boost, but some of my systems can no longer compile Bitcoin Core and upstreaming the patches avoids others running into the same issue.
