Bumps fmt from 12.2.0.bcr.1-codeql.1 to 12.2.0.bcr.1.

Release notes

Sourced from fmt's releases.

12.2.0

• Added a C11 API that brings fast, type-safe formatting to C. The new fmt-c library and fmt/fmt-c.h header use _Generic to dispatch on argument types and outperform printf/sprintf. For example:

  #include <fmt/fmt-c.h>
  fmt_print(stdout, "The answer is {}.\n", 42);

  (fmtlib/fmt#4663, fmtlib/fmt#4671, fmtlib/fmt#4696, fmtlib/fmt#4693, fmtlib/fmt#4694, fmtlib/fmt#4712, fmtlib/fmt#4789). Thanks @​Soumik15630m, @​Ferdi265 and @​localspook.

• Added a separate fmt::fmt-module CMake target for C++20 modules and a CI workflow that exercises module-based builds (fmtlib/fmt#4684, fmtlib/fmt#4685, fmtlib/fmt#4707, fmtlib/fmt#4708, fmtlib/fmt#4702, fmtlib/fmt#4709). Thanks @​MathewBensonCode.

• Enabled the full Dragonbox lookup cache by default for floating-point formatting unless optimizing for binary size (__OPTIMIZE_SIZE__), giving a ~10–25% speedup. Thanks Matthias Kretz for the suggestion. Average time per double on Apple M1 Pro (clang 17, random digits, smaller is better) measured with dtoa-benchmark:

  Method	Time (ns)
  fmt (full)	22.07
  fmt (compact)	29.55
  ryu	35.21
  double-conversion	81.81
  sprintf	726.27
  ostringstream	864.34

• Improved integer formatting performance by ~3% (fmtlib/fmt#4630). Thanks @​user202729.

• Optimized formatting into back-insert iterators by using bulk container append/insert methods (e.g. on std::vector<char> and custom string types) (fmtlib/fmt#4679). Thanks @​user202729.

• Reduced binary size of debug builds (~200k to ~85k in the bloat test) and improved compile speed when consteval is unavailable.

• Made path formatting lossless, preserving ill-formed UTF-16 sequences when converting std::filesystem::path to a narrow string.

• Added support for formatting std::unexpected (fmtlib/fmt#4675). Thanks @​17steen.

• Added overloads of fmt::println that take a fmt::text_style (fmtlib/fmt#4782). Thanks @​ahoarau.

• Added support for positional arguments as width and precision specifiers in fmt::printf (fmtlib/fmt#4643). Thanks @​KareemOtoum.

• Made FMT_STRING a no-op when FMT_USE_CONSTEVAL is enabled, since the consteval format-string constructor already provides compile-time validation (fmtlib/fmt#4611, fmtlib/fmt#4612). Thanks @​friedkeenan.

• Promoted fmt::detail::named_arg to the public API as fmt::named_arg and deprecated the detail alias (fmtlib/fmt#4683, fmtlib/fmt#4687). Thanks @​TPPPP72.

• Moved the std::byte formatter from fmt/format.h to fmt/std.h.

• Provided a default definition for fmt::is_contiguous (fmtlib/fmt#4731, fmtlib/fmt#4770). Thanks @​user202729 and @​phprus.

• Added the FMT_USE_FLOCKFILE macro to disable the use of flockfile (fmtlib/fmt#4646, fmtlib/fmt#4666). Thanks @​mvastola.

• Added include_guard(GLOBAL) so that {fmt} can be used in multiple submodules of the same project (fmtlib/fmt#4672). Thanks @​torsten48.

Changelog

Sourced from fmt's changelog.

12.2.1 - TBD

• Added a formatter for std::exception_ptr that formats the referenced exception (or none when null) (fmtlib/fmt#4808, fmtlib/fmt#4819). Thanks @​avikivity and @​Atlas-Zero.

• Added unwinding of nested exceptions created via std::throw_with_nested to the std::exception formatter, joining each level with ": " (fmtlib/fmt#4844). Thanks @​avikivity.

• Exported the ostream formatters (fmt::basic_ostream_formatter, fmt::ostream_formatter) and fmt::streamed from the C++20 module (fmtlib/fmt#4861). Thanks @​avikivity.

• Documented how to use the C++20 module with CMake, including the fmt::fmt-module target and compiler requirements (fmtlib/fmt#4237).

• Optimized 128-bit integer formatting by reducing the value to 64-bit chunks instead of doing repeated 128-bit division, giving a ~5x speedup on full-range values.

• Fixed handling of out-of-range floating-point durations in chrono formatting (fmtlib/fmt#4802). Thanks @​aizu-m.

• Fixed a hang and assertion failure when printing to a pipe whose read end is closed (fmtlib/fmt#4797). Thanks @​nikola-sh.

• Fixed formatting of out-of-range integers with the c presentation type, which previously mangled negative values and silently truncated out-of-range ones (fmtlib/fmt#4839). Thanks @​igoloe.

• Fixed an FMT_COMPILE failure for user-defined types formatted via format_as (fmtlib/fmt#4794, fmtlib/fmt#4836). Thanks @​mjerabek and @​upadhyay74aman.

• Fixed the fallback uint128 bitwise-not implementation (fmtlib/fmt#4813). Thanks @​Vcode2407.

• Fixed a false positive in fmt::is_contiguous by explicitly checking for operator[] on the container itself (fmtlib/fmt#4825). Thanks @​tearfur.

• Generated the build-tree CMake export set regardless of FMT_INSTALL,

🟡 Changes recommended

The proposed fmt version both drops the MSVC-specific fix needed for Windows builds and is unavailable in the repository’s prioritized local Bazel registry, causing build failure and module-resolution errors.

2 open issues

• Local Bazel registry cannot resolve the upstream fmt version · New
• Upstream fmt version drops the MSVC UTF-8 workaround · New

What changed in this PR

Updates the Bazel-managed fmt dependency from CodeQL’s patched 12.2.0.bcr.1-codeql.1 module to upstream 12.2.0.bcr.1.

Changes:

• Changes the declared fmt module version in MODULE.bazel.
• Removes reliance on the CodeQL-specific module overlay and its Windows compatibility workaround.
• The upstream version is not currently available through the repository’s prioritized local registry and may reintroduce Windows build failures.

This pull request requires changes.

File	Summary
MODULE.bazel	Updates the fmt Bazel module version, but should retain the CodeQL-patched dependency or update the local registry and upstream the required Windows compatibility fix before switching versions.

_{Review effort: Lite (auto)}

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
