* Fix LightGBM models locale sensitivity and improve R/W performance. When Java is used, the default C++ locale is broken. This is true for Java providers that use the C API or even Python models that require JEP. This patch solves that issue making the model reads/writes insensitive to such settings. To achieve it, within the model read/write codebase: - C++ streams are imbued with the classic locale - Calls to functions that are dependent on the locale are replaced - The default locale is not changed! This approach means: - The user's locale is never tampered with, avoiding issues such as https://github.com/microsoft/LightGBM/issues/2979 with the previous approach https://github.com/microsoft/LightGBM/pull/2891 - Datasets can still be read according the user's locale - The model file has a single format independent of locale Changes: - Add CommonC namespace which provides faster locale-independent versions of Common's methods - Model code makes conversions through CommonC - Cleanup unused Common methods - Performance improvements. Use fast libraries for locale-agnostic conversion: - value->string: https://github.com/fmtlib/fmt - string->double: https://github.com/lemire/fast_double_parser (10x faster double parsing according to their benchmark) Bugfixes: - https://github.com/microsoft/LightGBM/issues/2500 - https://github.com/microsoft/LightGBM/issues/2890 - https://github.com/ninia/jep/issues/205 (as it is related to LGBM as well) * Align CommonC namespace * Add new external_libs/ to python setup * Try fast_double_parser fix #1 Testing commit e09e5aad828bcb16bea7ed0ed8322e019112fdbe If it works it should fix more LGBM builds * CMake: Attempt to link fmt without explicit PUBLIC tag * Exclude external_libs from linting * Add exernal_libs to MANIFEST.in * Set dynamic linking option for fmt. * linting issues * Try to fix lint includes * Try to pass fPIC with static fmt lib * Try CMake P_I_C option with fmt library * [R-package] Add CMake support for R and CRAN * Cleanup CMakeLists * Try fmt hack to remove stdout * Switch to header-only mode * Add PRIVATE argument to target_link_libraries * use fmt in header-only mode * Remove CMakeLists comment * Change OpenMP to PUBLIC linking in Mac * Update fmt submodule to 7.1.2 * Use fmt in header-only-mode * Remove fmt from CMakeLists.txt * Upgrade fast_double_parser to v0.2.0 * Revert "Add PRIVATE argument to target_link_libraries" This reverts commit 3dd45dde7b92531b2530ab54522bb843c56227a7. * Address James Lamb's comments * Update R-package/.Rbuildignore Co-authored-by:
