Had to increase c++ version from c++17 to c++20 to use std::format Updated 38459f1 -> 6fb6897 ( |
Contributor
std::format isn't available in g++12, or clang-16 either, so this could lead to issues later on? |

Thanks, this is good to know. Can revert std::format changes if needed later. They are definitely non-essential. |

Partially revert bitcoin-core#156 due to lack of compiler support for std::format, as reported bitcoin-core#156 (comment) and bitcoin/bitcoin#31741 (comment) Technically it means this code is using locale dependent functions again, though I think in practice results will not be locale dependent because these are just integers not floating point numbers being formatted. This code could be written to use std::to_chars and be more independent, at the cost being slightly more complicated. Could be considered for a followup.

There was a problem hiding this comment.
Not sure std::format works with current Bitcoin Core head:
https://github.com/bitcoin/bitcoin/blob/fb0ada982a73687520c43b8fde480fa5d456f3e1/doc/dependencies.md
Clang 16 < 17 which is required for the full "Texture Formatting" feature set according to https://en.cppreference.com/w/cpp/compiler_support/20#C.2B.2B20_library_features
Seems to check out on Godbolt: https://godbolt.org/z/9Ybd65f4d

Bump libmultiprocess library to include bugfix bitcoin-core/libmultiprocess#159 which should fix intermittent CI failure reported bitcoin#31921 This change is bumping the libmultiprocess version instead of cherry picking the bugfix. It could cherry-pick the bugfix instead, but there are reasons to prefer just bumping the version: - Bugfix might interact with earlier PRs, and the latest version is better tested with testing done in many CI configurations in bitcoin#30975 and bitcoin#31802 - Even though we are in feature freeze for a release, the MULTIPROCESS=1 option is currently not enabled for release, so this PR only affect CI builds and local builds, not the release build. bitcoin-core/libmultiprocess#140 build: don't clobber user/superproject c++ version bitcoin-core/libmultiprocess#142 build: add option for external mpgen binary bitcoin-core/libmultiprocess#143 cleanup: initialize vars in the EventLoop constructor in the correct order bitcoin-core/libmultiprocess#146 cmake: Suppress compiler warnings from capnproto headers bitcoin-core/libmultiprocess#147 cmake: EXTERNAL_MPGEN cleanups bitcoin-core/libmultiprocess#148 util: fix -Wpessimizing-move warning bitcoin-core/libmultiprocess#145 CTest: Module must be included at the top level bitcoin-core/libmultiprocess#149 Avoid `-Wundef` compiler warnings bitcoin-core/libmultiprocess#152 refactor: Fix compiler and clang-tidy warnings bitcoin-core/libmultiprocess#155 scripted-diff: s/Libmultiprocess_EXTERNAL_MPGEN/MPGEN_EXECUTABLE/g bitcoin-core/libmultiprocess#156 refactor: Remove locale-dependent function calls bitcoin-core/libmultiprocess#157 refactor: Avoid using std::format bitcoin-core/libmultiprocess#159 bugfix: Do not lock EventLoop::mutex after EventLoop is done bitcoin-core/libmultiprocess#161 cmake: Avoid including CTest if not top level project bitcoin-core/libmultiprocess#164 Bump minimum required cmake to 3.12
