Update dependencies

[thejohnfreeman]

This change updates our dependencies to the most recent versions in Conan Center. cassandra-cpp-driver cannot compile as C++20. I don't know how the Clio team is doing it.

The only code changes required are related to (a) missing includes and (b) multiple string_views in Boost. rippled uses Boost.Beast which now uses a boost::core::string_view that is different from boost::utility::string_view. boost::core::string_view was added to Boost on Oct 4, 2021, after the release of 1.77 which we had been using, and before the release of 1.78. It is missing the to_string() method that boost::utility::string_view has and that we had been calling.

FWIW, this branch does not build for me on my local machine. I'm using clang on macOS. Conan is apparently using boost 1.77. I made a commit that does build on my local machine. Basically I turned selected implicit conversions to std::string into explicit conversions to std::string. However I can't swear it will build for anybody else. The commit is topmost here, just in case it is useful: https://github.com/scottschurr/rippled/commits/john-deps

[scottschurr]

Okay, that last comment was not accurate since I did not clear the ~/.conan/data cache. I still have two build problems using macOS, clang 13 and boost 1.82.0. The top-most commit here fixes the two build errors that I saw: https://github.com/scottschurr/rippled/commits/john-deps

Those fixes worked for me on macOS 12.6.3, Clang 14.0.0, Boost 1.82.0. I copied them over. Let's see how they do in CI. CI uses Clang 16. I'm installing that in my VM for testing now.

[thejohnfreeman]

Clang 16 fails because of a compiler regression involving -std=c++20 and concept template parameters. There is a workaround patch for the Boost.Beast source, but I am testing a compiler flag workaround.

[thejohnfreeman]

Compiler flag worked. No errors, but have some residual warnings. Will work on eliminating them.

[scottschurr]

Latest version is working for me. Thanks for doing this!

I'm seeing the following error:

ERROR: Conflict in googleapis/cci.20221108:
    'googleapis/cci.20221108' requires 'protobuf/3.21.4' while 'googleapis/cci.20221108' requires 'protobuf/3.21.9'.
    To fix this conflict you need to override the package 'protobuf' in your root package.

I haven't looked into this yet, just posting the issue in case anyone knows of a quick fix.

[scottschurr]

@seelabs, I saw that error. As I recall it was cleaned up when I cleared my ~/.conan/data directory. Something to try if you haven't done that yet.

[seelabs]

@scottschurr Thanks! That got me past that error.

RocksDB 6.x.x is not ready for GCC 13 (facebook/rocksdb#11157). I'll try adapting a recipe for RocksDB 8.x.x Monday and test compile our code against it.

[seelabs]

I was able to build and test this with gcc 13, but only by manually editing some files in .conan/data for both rocksdb and boost (both required adding a new #include <cstdint>). I don't think this is a reason to hold up the PR though. We can add patches to support gcc13 in a different PRl

[ximinez]

Builds fine in Windows. I'm curious to see how this interacts with #4596

[intelliot]

for next week: if this is ready to merge, go ahead and bring it up-to-date with the base branch (preferably with a merge commit).

(I don't have permission to push to the PR branch)

Suggested commit message:

Update dependencies (#4595)

Use the most recent versions in ConanCenter.

* Due to a bug in Clang 16, you may get a compile error:
  "call to 'async_teardown' is ambiguous"
  * A compiler flag workaround is documented in `BUILD.md`.
* At this time, building this with gcc 13 may require editing some files
  in `.conan/data`
  * A patch to support gcc13 may be added in a later PR.

After this commit, you may need to:

1. Remove or empty your build directory.
2. Remove the Conan cache, i.e. rm -rf ~/.conan/data
