fanquake 335bd7f8bc build: use patch rather than sed in Boost package
The depends comment is actually incorrect, and this can be dropped once
we move to 1.71.0 or later.

1ccb9f30c0 Move Win32 defines to configure.ac to ensure they are globally defined (Luke Dashjr)

Pull request description:

  #9245 no longer needs this, since the main `_WIN32_WINNT` got bumped by something else.

  So rather than just lose it, might as well get it merged in independently.

  I'm not aware of any practical effects, but it seems safer to use the same API versions everywhere.

366913e307 build: AX_BOOST_THREAD serial 33 (Igor Cota)
cf0681133a build: disable D-Bus on Android by default (Igor Cota)

Pull request description:

  I've been trying to build for Android on different OSes/Gitian with varying success. Build system is quite the beast and sometimes it doesn't get it right. To make sure it does these three little tweaks make the Android build more robust:

  - disable D-Bus (Android doesn't support it and has its own way to trigger notifications)
  - don't flag `-lpthread` when linking Boost, [Bionic has built-in support](https://stackoverflow.com/questions/30801752/android-ndk-and-pthread)
  - ~~add `-static-libstdc++` to linker flags. This avoids having to bundle `libc++_shared` with CLI apps, still necessary with `bitcoin-qt` though (thanks Sjors)~~

  I think these are small and fairly straightforward so I put them all into this one PR.

Pull request description:

  Enable some commonly enabled compiler diagnostics as discussed in #17344.

  | Compiler diagnostic | no# of emitted unique GCC warnings in `master` | no# of emitted unique Clang warnings in `master` |
  | ------------- | ------------- | ------------- |
  | `-Wduplicated-branches`: Warn if `if`/`else` branches have duplicated code  | 0 | Not supported |
  | `-Wduplicated-cond`: Warn if `if`/`else` chain has duplicated conditions  | 0 | Not supported |
  | `-Wlogical-op`: Warn about logical operations being used where bitwise were probably wanted  | 0 | Not supported |
  | `-Woverloaded-virtual`: Warn if you overload (not `override`) a virtual function  | 0 | 0 |
  | ~~`-Wunused-member-function`: Warn on unused member function~~  | Not supported | 2 |
  | ~~`-Wunused-template`: Warn on unused template~~ | Not supported | 1 |

  There is a large overlap between this list and [Jason Turner's list of recommended compiler diagnostics in the Collaborative Collection of C++ Best Practices (`cppbestpractices`) project](https://github.com/lefticus/cppbestpractices/blob/master/02-Use_the_Tools_Available.md#gcc--clang). There is also an overlap with the recommendations given in the [C++ Core Guidelines](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines) (with editors Bjarne Stroustrup and Herb Sutter).

fanquake c0b1706964 Merge #19568: Wallet should not override signing errors
e7448d6680 wallet: Don't override signing errors (Fabian Jahr)

Pull request description:

  While reviewing #17204 I noticed that the errors in `input_errors` from `::SignTransaction` where being overridden by `CWallet::SignTransaction`. For example, a Script related error led to incomplete signature data which led to `CWallet::SignTransaction` reporting that keys were missing, which was a less precise error than the original one.

  Additionally, the error `"Input not found or already spent"` is [duplicated in `sign.cpp`](https://github.com/bitcoin/bitcoin/blob/c7b4968552c704f1e2e9a046911e1207f5af5fe0/src/script/sign.cpp#L481), so the error here is redundant at the moment. So technically the whole error block could be removed, I think. However, this code is affected by the ongoing work on the wallet so there might be a reason why these errors are here. But even if there is a reason to keep them, I don't think existing, potentially more precise errors should be overridden here unless we want to hide them from the users. I am looking for feedback if this is a work in progress state where these errors could be more useful in the future or if they can be removed.

  On testing: even though [the errors in `CWallet` are covered](https://marcofalke.github.io/btc_cov/total.coverage/src/wallet/wallet.cpp.gcov.html), all tests still pass after removing them. I am not sure if there is a desire to cover these specific error messages, tests in `test/functional/rpc_signrawtransaction.py` seem to aim for a more generic approach.

Pull request description:

  **This is part 1 of #19315, which enables the ability to test `outbound` and `block-relay-only` connections from the functional tests.** Please see that PR for more information of overall functionality.

  **This PR simplifies how we manage different connection types.** It introduces an enum with the various types of connections so we can explicitly define the connection type. The existing system relies on a series of independent flags, then has asserts scattered around to ensure that conflicting flags are not enabled at the same time. I find this approach to be both brittle and confusing. While making these changes, I found a small bug due to the silent assumptions.

  This PR also proposes a rename from `OneShot` to `AddrFetch`. I find the name `OneShot` to be very confusing, especially when we also have `onetry` manual connections. Everyone I've talked to offline has agreed that the name is confusing, so I propose a potential alternative. I think this is a good opportunity for a rename since I'm creating an enum to explicitly define the connection types.
  (some context for the unfamiliar: `oneshot` or `addrfetch` connections are short-lived connections created on startup. They connect to the seed peers, send a `getaddr` to solicit addresses, then close the connection.)

  Overview of this PR:
  * rename `oneshot` to `addrfetch`
  * introduce `ConnectionType` enum
  * one by one, add different connection types to the enum
  * expose the `conn_type` on CNode, and use this to reduce reliance on flags (& asserts)
  * fix the bug in counting different type of connections
  * some additional cleanup to simplify logic and make expectations explicit/inclusive rather than implicit/exclusive.

fanquake cb1ee1551c Merge #19674: refactor: test: use throwaway _ variable for unused loop counters
dac7a111bd refactor: test: use _ variable for unused loop counters (Sebastian Falbesoner)

Pull request description:

  This tiny PR substitutes Python loops in the form of `for x in range(N): ...` by `for _ in range(N): ...` where applicable. The idea is indicating to the reader that a block (or statement, in list comprehensions) is just repeated N times, and that the loop counter is not used in the body, hence using the throwaway variable. This is already done quite often in the current tests (see e.g. `$ git grep "for _ in range("`). Another alternative would be using `itertools.repeat` (according to Python core developer Raymond Hettinger it's [even faster](https://twitter.com/raymondh/status/1144527183341375488)), but that doesn't seem to be widespread in use and I'm not sure about a readability increase.

  The only drawback I see is that whenever one wants to debug loop iterations, one would need to introduce a loop variable again. Reviewing this is basically a no-brainer, since tests would fail immediately if a a substitution has taken place on a loop where the variable is used.

  Instances to replace were found by `$ git grep "for.*in range("` and manually checked.

9f88ded82b test addition of unknown segwit spends to txid reject filter (Gregory Sanders)
7989901c7e Add txids with non-standard inputs to reject filter (Suhas Daftuar)

Pull request description:

  Our policy checks for non-standard inputs depend only on the non-witness
  portion of a transaction: we look up the scriptPubKey of the input being
  spent from our UTXO set (which is covered by the input txid), and the p2sh
  checks only rely on the scriptSig portion of the input.

  Consequently it's safe to add txids of transactions that fail these checks to
  the reject filter, as the witness is irrelevant to the failure. This is helpful
  for any situation where we might request the transaction again via txid (either
  from txid-relay peers, or if we might fetch the transaction via txid due to
  parent-fetching of orphans).

  Further, in preparation for future witness versions being deployed on the
  network, ensure that WITNESS_UNKNOWN transactions are rejected in
  AreInputsStandard(), so that transactions spending v1 (or greater) witness
  outputs will fall into this category of having their txid added to the reject
  filter.

Pull request description:

  This is based on https://github.com/bitcoin/bitcoin/pull/18044#discussion_r450687076.

  A new type `GenTxid` is added to protocol.h, which represents a tagged txid-or-wtxid. The tx request logic is updated to use these instead of uint256s, permitting per-announcement distinguishing of txid/wtxid (instead of assuming that everything we want to request from a wtxid peer is wtx). Then the restriction of orphan-parent requesting to non-wtxid peers is lifted.

  Also document BIP339 in doc/bips.md.

This also aligns our code more closely with what is being done in leveldb.

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

fanquake 2e9e6377f1 build: add -Wl,-z,separate-code to hardening flags
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):

c0f09c2c9d fuzz: add missing overrides to signature_checker (Jon Atack)

Pull request description:

  These functions in `fuzz/signature_checker.cpp` override virtual member functions and should be marked `override` instead of `virtual`, which is for introducing a new virtual function. The overridden virtual functions are in `script/interpreter.h:151/156/161`.

  Also, per MarcoFalke suggestion, add missing parentheses in `fuzz/scriptnum_ops.cpp` and remove useless `unsigned int >= 0` conditional in `fuzz/script.cpp`.

  These changes fix 5 compile warnings in gcc 10 and 3 in clang 11/12.

fanquake 2a701a1c42 build: pass -fcommon when building genisoimage
Starting with the 10.1 release, GCC defaults to -fno-common. This causes
linking issues when building genisoimage:
```bash
[ 98%] Building C object genisoimage/CMakeFiles/genisoimage.dir/checksum.o
[100%] Linking C executable genisoimage
/usr/bin/ld: CMakeFiles/genisoimage.dir/apple.o:(.bss+0x0): multiple definition of `outfile'; CMakeFiles/genisoimage.dir/genisoimage.o:(.bss+0x0): first defined here

```

Rather than patching genisoimage further, pass -fcommon to preserve the
legacy GCC behaviour.

  This replaces: #17099

  -----

  This patchset allows us to force depends to use system clang.

  Previously, #17099 removes our dependency on a specific clang we download from llvm.org, but theuni pointed out that since OSX builds are only ever built with a version of clang that is chosen and "blessed" by Apple, it is more likely that the user will encounter problems if they use their system clang. This patchset forces the user to set `FORCE_USE_SYSTEM_CLANG=1` in order to use their system clang (when they know what they're doing)

Debian GCC ignores -Wformat-security, without -Wformat, which
means when we test for it, it currently fails:

```bash
checking whether C++ compiler accepts -Wformat-security... no
...
configure:15907: checking whether C++ compiler accepts -Wformat-security
configure:15926: g++ -std=c++11 -c -g -O2 -Werror -Wformat-security  conftest.cpp >&5
cc1plus: error: '-Wformat-security' ignored without '-Wformat' [-Werror=format-security]
cc1plus: all warnings being treated as errors
```

Fix this by just combining the -Wformat and -Wformat-security checks
together.

Pull request description:

  This implements the follow-up suggested here: https://github.com/bitcoin/bitcoin/pull/18861#issuecomment-627630111 . Instead of checking `setInventoryTxToSend`, maintain an explicit bloom filter with the 3500 most recently announced invs, and permit fetching any of these as long as they're in the relay pool or the mempool. In addition, permit relay from the mempool after just 2 minutes instead of 15.

  This:

  * Fixes the brief opportunity an attacker has to request unannounced invs just after the connection is established (pointed out by naumenkogs, see https://github.com/bitcoin/bitcoin/pull/18861#issuecomment-627627010).
  * Guarantees that locally resubmitted invs after `filterInventoryKnown` rolls over can still be requested (pointed out by luke-jr, see https://github.com/bitcoin/bitcoin/pull/18861#discussion_r419695831).

  It adds 37 KiB of filter per peer.

  This is also a step towards dropping the relay pool entirely and always relaying from the mempool directly (see #17303), but that is still blocked by dealing properly with NOTFOUNDs (see #18238).

fanquake f61019f5a2 Merge #19407: doc: explain why passing -mlinker-version is required when cross-compiling
a8d39b8840 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.

  Note: To add a little more confusion, you wont see `-mlinker-version X` in your compile flags, you'll see [`-target-linker-version X`](https://github.com/llvm/llvm-project/blob/431daedee4dcce0c096c400dbf8e64dfe7254fb6/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(...)` :)

  Ok, I have been convinced that I was too clever with the refactor and I have removed it. Now it's just the tiny change to fix the build on my local machine.

  ---

  On OS X, when searching Homebrew keg-only packages for BDB 4.8, if we find it,
  use BDB_CPPFLAGS and BDB_LIBS instead of CFLAGS and LIBS for the result. This
  is (1) more correct, and (2) necessary in order to give this location
  priority over other directories in the include search path, which may include
  system include directories with other versions of BDB.

fanquake 9952242c03 build: improve builtin_clz* detection
The way we currently test with AC_CHECK_DECLS do not work with Clang:
```bash
configure:21492: clang++-10 -std=c++11 -c -g -O2  -DHAVE_BUILD_INFO -D__STDC_FORMAT_MACROS conftest.cpp >&5
conftest.cpp:100:10: error: builtin functions must be directly called
  (void) __builtin_clz;
         ^
1 error generated.
```

This also removes the __builtin_clz() check, as we don't actually use
it anywhere, and it's trvial to re-add detection if we do start using
it at some point.

b3394ab235 contrib: macdeploy: Correctly generate macOS SDK (Carl Dong)

Pull request description:

  This PR achieves 3 main things:
  1. It simplifies the macOS SDK generation by putting the logic inside a (semi-)portable python3 script `gen-sdk`
  2. It transitions us to using `libc++` headers extracted from the `Xcode.app`, which is more correct as those headers better match the `.tbd` library stubs we use from the `MacOSX.sdk` (located under the same `Xcode.app`). Previously, we used `libc++` headers copied from our downloaded, pinned clang (see `native_cctools.mk`).
  3. It bumps the macOS toolchain in a way that fulfills all of the following constraints:
      1. The new SDK should support compiling with C++17 (our current one doesn't)
      2. The new toolchain should not change our minimum supported macOS version (`-mmacosx-version-min`)
      3. The new toolchain should expect to use a version of `cctools` that is supported by https://github.com/tpoechtrager/cctools-port

  For the constraints in (3), you can reference [this chart](https://en.wikipedia.org/wiki/Xcode#Xcode_7.0_-_11.x_(since_Free_On-Device_Development)) to see that the newest toolchain we can use with our `cctools-port` is `11.3.1`, and the rest of the constraints were tested with local builds.

  #### But [the other Wikipedia chart](https://en.wikipedia.org/wiki/Xcode#Xcode_11.x_(since_SwiftUI_framework)) says that the "min macOS to run" for Xcode 11.3.1 is 10.14.4, doesn't that violate constraint (ii)?

  This confused me at first too, but the "min macOS to run" is for the Xcode.app App itself. The SDK still supports 10.12, as evident in a few plist files and as proven through local builds.

  #### Why bundle all of this together in a single PR?

  We need (1) and (2) together, because if we don't, manually adding the `libc++` headers and writing that out in a `README.md` is going to result in a lot of user error, so it's great to have these together to be more correct and also make it easier on the user at the same time.

  We need (3) together with everything else because bumping (or in the case of (1), renaming) the SDK requires some human coordination and may break some builds. And since it's not that complicated a change, it makes sense to do it together with the rest.

f52d403b81 [net] split PushInventory() (John Newbery)

Pull request description:

  PushInventory() is currently called with a CInv object, which can be a
  MSG_TX or MSG_BLOCK. PushInventory() only uses the type to determine
  whether to add the hash to setInventoryTxToSend or
  vInventoryBlockToSend.

  Since the caller always knows what type of inventory they're pushing,
  the CInv is wastefully constructed and thrown away, and tx/block relay
  is being split out, we split the function into PushTxInventory() and
  PushBlockInventory().

ff8c430c65 [test] test disconnect for filterclear (gzhao408)
1c6b787e03 [netprocessing] disconnect node that sends filterclear (gzhao408)

Pull request description:

  Nodes that don't have bloomfilters turned on (i.e. no `NODE_BLOOM` service) should disconnect peers that send them `filterclear` P2P messages.

  Non-bloomfilter nodes already disconnect peers for [`filteradd` and `filterload`](https://github.com/bitcoin/bitcoin/blob/19e919217e6d62e3640525e4149de1a4ae04e74f/src/net_processing.cpp#L2218), but #8709 removed `filterclear` so it could be used to reset tx relay. This isn't needed now because using `feefilter` message is much better for this purpose (See #19204).

  Also refactors existing disconnect logic for `filteradd` and `filterload` into respective message handlers and removes banning for them.

Pull request description:

  This PR makes `bitcoin_qt.m4` to use `pkg-config` for all hosts and removes non-pkg-config paths from it. This is a step towards the idea which was clear [stated](https://github.com/bitcoin/bitcoin/pull/8314#issue-76644643) by Cory Fields:
  > I believe the consensus is to treat Windows like the others and require pkg-config across the board. We can drop all of the non-pkg-config paths, and simply AC_REQUIRE(PKG_PROG_PKG_CONFIG)

  There are two unsolved problems with this PR. If depends is built with `DEBUG=1` the `configure` script fails to pickup Qt:
  - for macOS host (similar to, but not the same as #16391)
  - for Windows host (regression)

  The fix is ~on its way~ submitted in #18298 (as a followup).

  Also this PR picks some small improvements from #17820.

fanquake c4ffcf07af build: remove BIP70 configure option
This was left in after #17165, so that anyone who had been compiling
with (already disabled by default) BIP70 would realise that support
had been completely removed in 0.20.0. However we should be able to
remove it for 0.21.0.

Pull request description:

  There are predefined interruption points for `boost::thread`: https://www.boost.org/doc/libs/1_71_0/doc/html/thread/thread_management.html#interruption_points

  However, non-boost threads such as `std::thread` or the `main()` thread can obviously not be interrupted. So remove all unused boost/thread from methods that are never executed in a `boost::thread`.

  Most of them were accompanied by a `ShutdownRequested` anyway. So even if the current thread was a `boost::thread`, the interruption point would be redundant. (We only interrupt threads during shutdown)

fanquake 234fabab90 Merge #18210: test: type hints in Python tests
bd7e530f01 This PR adds initial support for type hints checking in python scripts. (Kiminuo)

Pull request description:

  This PR adds initial support for type hints checking in python scripts.

  Support for type hints was introduced in Python 3.5. Type hints make it easier to read and review code in my opinion. Also an IDE may discover a potential bug sooner. Yet, as PEP 484 says: "It should also be emphasized that Python will remain a dynamically typed language, and the authors have no desire to ever make type hints mandatory, even by convention."

  [Mypy](https://mypy.readthedocs.io/en/latest/index.html) is used in `lint-python.sh` to do the type checking. The package is standard so there is little chance that it will be abandoned. Mypy checks that type hints in source code are correct when they are not, it fails with an error.

  **Notes:**

  * [--ignore-missing-imports](https://mypy.readthedocs.io/en/latest/command_line.html#cmdoption-mypy-ignore-missing-imports) switch is passed on to `mypy` checker for now. The effect of this is that one does not need `# type: ignore` for `import zmq`. More information about import processing can be found [here](https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports). This can be changed in a follow-up PR, if it is deemed useful.
  * We are stuck with Python 3.5 until 04/2021 (see https://packages.ubuntu.com/xenial/python3). When Python version is bumped to 3.6+, one can change:
      ```python
      _opcode_instances = []  # type: List[CScriptOp]
      ```
      to
      ```python
      _opcode_instances:List[CScriptOp] = []
      ```
      for type hints that are **not** function parameters and function return types.

  **Useful resources:**

  * https://docs.python.org/3.5/library/typing.html
  * https://www.python.org/dev/peps/pep-0484/

ACKs for top commit:
  fanquake:
    ACK bd7e530f01 - the type checking is not the most robust (there are things it fails to detect), but I think this is worth adopting (in a limited capacity while we maintain 3.5 compat).
