37ae687f95 Add tests for CPubKey serialization/unserialization (Elichai Turkel)
9b8907fade Check size after Unserializing CPubKey (Elichai Turkel)
Pull request description:
Found by practicalswift, closes#19235
Currently all the public API(except the pointer-like API) in CPubKey that sets/constructs a pubkey goes through `CPubKey::Set` which checks if that the length and size match and if not invalidates the key.
This adds the same check to `CPubKey::Unserialize`, sadly I don't see an easy way to just push this to the existing checks in `CPubKey::Set` but it's only a simple condition.
The problem with not invalidating is that if you write a pubkey like: `{0x02,0x00}` it will think the actual length is 33(because of `size()`) and will access uninitialized memory if you call any of the functions on CPubKey.

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.

f1d21ef1c3 doc: add C++17 release note for 0.21.0 (fanquake)
Pull request description:
TLDR: Mention that the codebase is now compatible with C++17, and that the
intention is to require C++17 starting with 0.22.0.
Following some discussion with Cory/Carl, and in #16684, I think this is the next step in the C++17 migration.
While #16684 mentions a gitian/Guix release with C++17, it's not yet clear how that would be done. Are we just going to pass `--enable-c++17` in gitian/Guix?. Are we changing our default in configure.ac?
According to the [last comment](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-643778757) in #16684, we wouldn't be changing anything in depends:
> No, everything (including depends) will stay at C++11.
However I don't think we want to be mixing C++11 built dependencies, with a C++17 built bitcoind, if there is any potential for compatibility issues.
Instead, I'd suggest we build the 0.21.0 release as C++11, and do a complete switch to C++17 for 0.22.0. Also, if we actually wanted to use C++17 in depends for 0.21.0, we couldn't without breaking C++11 compat (Qt). See below.
Here is a potential timeline/TODOs for the migration:
Potential Timeline
* 17 / 6 / 2020 - Today
* Some time prior to split-off:
* Confirm that compiling with C++17 works.
* Confirm that C++11 compatibility has not been broken.
* 1 / 11 / 2020
* [0.21.0 split off happens](https://github.com/bitcoin/bitcoin/issues/18947).
* 2 / 11 / 2020
* Merge an "incompatible with C++11" change into master.
* Switch configure to use C++17 mode by default.
* Update minimum compiler requirements. At least:
* Clang 5: https://clang.llvm.org/cxx_status.html#cxx17
* GCC 7: https://gcc.gnu.org/projects/cxx-status.html#cxx17
* While GCC has some support from 5, it seems a more complete support landed in GCC 7.
* https://gcc.gnu.org/gcc-7/changes.html#cxx
* Switch depends packages to use C++17 where applicable.
* Bump Qt from 5.9.x (no c++17 mode) to, likely, 5.15.x (LTS).
* Drop support for macOS < 10.14.x
* The c++ dylib shipped with macOS [doesn't support c++17, prior to macOS 10.14](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-643722538).
* Building Qt 5.12 or 5.15 in C++17 mode will also require a minimum macOS deployment target of 10.14. https://codereview.qt-project.org/c/qt/qtbase/+/283832.
* Begin merging PRs like #19183 and #19245.
* I've left some comments in #19183 if the macOS runtime issue interests anyone.
* 3 / 12 / 2020
* 0.21.0 released.
* Built as C++11.
* Contains warning in release notes that compiling 0.22.0 will require C++17.
* 3 / 6 / 2021
* 0.22.0 released.
* Full of C++17 code.
One thing worth noting, is that we cannot bump our Qt to a newer LTS for 0.21.0, without breaking C++11 compatibility. Qt 5.12 is not compilable in C++11 mode, as the project has started using C++14 features throughout at least the macOS portions of it's codebase, and seemingly "forgotten" that the release is meant to be C++11 compatible.
Upstream bug here: https://bugreports.qt.io/browse/QTBUG-77310.
> Building Qt requires C+11, at a minimum, but in practice we use later features, usually under a feature define, or with a fallback of some kind. On platforms that support > C11, we've (apparently) not considered the fallback necessary, under the assumption C+14 is always available.

Pull request description:
Add a "PSBT Operations" dialog, reached from the "Load PSBT..." menu item, giving options to sign or broadcast the loaded PSBT as appropriate, as well as copying the result to the clipboard or saving it to a file.
This is based on Sjors' #17509, and depends on that PR going in first. (It effectively replaces the small "load PSBT" dialog from that PR with a more feature-rich one.)
Some notes:
* The way I display status information is maybe unusual (a status bar, rather than messageboxes.) I think it's helpful to have the information in it be persistent rather than transitory. But if people dislike it, I would probably move the "current state of the transaction" info to the top line of the main label, and the "what action just happened, and did it succeed" info into a messagebox.
* I don't really know much about the translation/localization stuff. I put tr() in all the places it seemed like it ought to go. I did not attempt to translate the result of TransactionErrorString (which is shared by GUI and non-GUI code); I don't know if that's correct, but it matches the "error messages in logs should be googleable in English" heuristic. I don't know whether there are things I should be doing to reduce translator effort (like minimizing the total number of distinct message strings I use, or something.)
* I don't really know how (if?) automated testing is applied to GUI code. I can make a list of PSBTs exercising all the codepaths for manual testing, if that's the right approach. Input appreciated.

Pull request description:
This PR continues and completes the work begun in #17700 working on issue #16000 to create a client-side version of RPC `generate`.
Basically, `bitcoin-cli -generate` wraps calling `generatenewaddress` followed by `generatetoaddress [nblocks] [maxtries]` and prints the following:
```
$ bitcoin-cli -generate
{
"address": "bcrt1qn4aszr2y2xvpa70y675a76wsu70wlkwvdyyln6"
"blocks": [
"01d2ebcddf663da90b28da7f6805115e2ba7818f16fe747258836646a43a0bb5",
]
}
$ bitcoin-cli -rpcwallet=wallet-name -generate 3 100
{
"address": "bcrt1q4cunfw0gnsj7g7e6mk0v0uuvvau9mwr09dj45l",
"blocks": [
"7a6650ca5e0c614992ee64fb148a7e5e022af842e4b6003f81abd8baf1e75136",
"01d2ebcddf663da90b28da7f6805115e2ba7818f16fe747258836646a43a0bb5",
"3f8795ec40b1ad812b818c177680841be319a3f6753d4e32dc7dfb5bafe5d00e"
]
}
```
Help doc:
```
$ bitcoin-cli -h | grep -A5 "\-generate"
-generate
Generate blocks immediately, equivalent to RPC generatenewaddress
followed by RPC generatetoaddress. Optional positional arguments
are number of blocks to generate (default: 1) and maximum
iterations to try (default: 1000000), equivalent to RPC
generatetoaddress nblocks and maxtries arguments. Example:
bitcoin-cli -generate 4 1000
```
Quite a bit of test coverage turned out to be needed to cover the change and the different cases (arguments, multiwallet mode) and error-handling.
This PR also improves some things that working on these changes brought to light.
Credit to Harris Brakmić for the initial work in #17700.
