9bd3f35003 build: adds switch for disabling random base addresses in MSVC (Ethan Heilman)
Pull request description:
In m4 builds we have the --disable-hardening switch that can be given in `./configure` to turn off randomized addresses. This PR provides a simple way of turning off randomized addresses in MSVC builds.
This PR:
* Adds this option the common-init project file so that it can be globally set across the project
* Documents this switch in msvc build readme
I have run the following test to verify this works
I ran the msvc build with `<RandomizedBaseAddress>true</RandomizedBaseAddress>` then checked `bitcoind.exe` and `bitcoin-cli.exe` with `dumpbin.exe`:
bitcoind
```
> .\dumpbin.exe /headers src/bitcoind.exe

Then I built with `<RandomizedBaseAddress>false</RandomizedBaseAddress>` then checked `bitcoind.exe` and `bitcoin-cli.exe` with `dumpbin.exe` and observed that `Dynamic base` was longer listed in `OPTIONAL HEADER VALUES`

Tidied up debug and release configuration blocks in common project file to avoid duplication.
Updated appveyor config to use latest Visual Studio 2019 image.
Changed appveyor config file hash to use a new version of Qt pre-compiled binaries built for Visual Studio 2019 v16.8.1.
Bumped vcpkg version to tag '2020.11-1' for binary caching feature.
See #20392 for related discussion.
The vcpkg tool has introduced a proper way to use manifests, https://devblogs.microsoft.com/cppblog/vcpkg-accelerate-your-team-development-environment-with-binary-caching-and-manifests/. This PR replaces the custom text file mechanism with the new manifest approach.
It is planned that vckpg manifests will include the ability to version dependencies in the future. Dependency versions would solve a number of issues that currently require workarounds with the appveyor CI.
Set vcpkg manifest version to 1 to avoid any perception it's related to any release or other version numbering.
- Update Visual Studio instructions.
- Remove x64 platform conditional from bitcoin-qt project configuration.
- Set use native environment toolset to fix linker warning.
- Ignore linker warning about precompiled type information missing for test_bitcoin_qt.
msvc warning C4834 for the Bitcoin Core build was introduced by Visual Studio 16.4.0. This PR adds an ignore rule for the warning (it's related to the nodiscard attribute and is not considered relevant).
An additional side effect of the msvc compiler update is the prebuilt Qt5.9.8 libraries cannot be linked due to being built with an earlier version of the compiler. To fix this a new Qt5.9.8 version has been compiled and the appveyor job updated to use them. The GitHub Actions job needs to continue to use the original Qt5.9.8 libraries until the latest GitHub Windows image also updates to >= Visual Studio 2019 v16.4.
- Update build image from Visual Studio 2017 to Visual Studio 2019.
- Updated Qt static library from Qt5.9.7 to Qt5.9.8.
- Added commands to update vcpkg port files (this does not update already installed packages).
- Updated vcpkg package list as per #17309.
- Removed commands setting common project file options. Now done via common.init.vcxproj include.
- Changed msbuild verbosity from normal to quiet. Normal rights a LOT of logs and impacts appveyor job duration.
Updated msvc project configs:
- Updated platform toolset from v141 to v142.
- Updated Qt static library from Qt5.9.7 to Qt5.9.8.
- Added ignore for linker warning building bitcoin-qt program.
- Added missing util/str.cpp class file to test_bitcoin project file.
