* Add capability to get possible max and min values for a model * Change implementation to have return value in tree.cpp, change naming to upper and lower bound, move implementation to gdbt.cpp * Update include/LightGBM/c_api.h Co-Authored-By:
Nikita Titov <nekit94-08@mail.ru> * Change iteration to avoid potential overflow, add bindings to R and Python and a basic test * Adjust test values * Consider const correctness and multithreading protection * Put everything possible as const * Include shared_mutex, for now as unique_lock * Update test values * Put everything possible as const * Include shared_mutex, for now as unique_lock * Make PredictSingleRow const and share the lock with other reading threads * Update test values * Add test to check that model is exactly the same in all platforms * Try to parse the model to get the expected values * Try to parse the model to get the expected values * Fix implementation, num_leaves can be lower than the leaf_value_ size * Do not check for num_leaves to be smaller than actual size and get back to test with hardcoded value * Change test order * Add gpu_use_dp option in test * Remove helper test method * Remove TODO * Add preprocessing option to compile with c++17 * Update python-package/setup.py Co-Authored-By:

In the current implementation, the index is an int32, which will segfault with large data sets and a large number of estimators.

* [performance] Add Fast methods to C API for SingleRow Predictions * Add methods to C API to make single-row predictions faster: - LGBM_BoosterPredictForMatSingleRowFastInit (setup) - LGBM_BoosterPredictForMatSingleRowFast (predict) - LGBM_FastConfigFree (cleanup setup outputs) * Code syle cleanup * Fix lint errors * [performance] Revert FastConfig improvement to pass data at init This reduces optimization by 5% / 30% with this branch but makes it so it can be used for higher level wrappers in MMLSpark. And outside it as well. * [performance] Introduce Fast variants for SingleRow predictors. Although this already provides performance gains by itself for any callers, two new functions were added to Java's SWIG interfaces to exploit that AND the GetPrimitiveArrayCritical data fetches. * [tests/profiling] Profile Fast predict methods Build with -DBUILD_PROFILING_TESTS=ON and copy the default model trained on the Higgs dataset from the benchmarks repo https://github.com/guolinke/boosting_tree_benchmarks.git to LightGBM repo root and run the lightgbm_profile_* binaries. The single instance used is the first row from that dataset. * Update comment on CMakeLists. * Fix doxygen-introduced issue (#threads) * Fix conflicts due to new RowFunctionFromCSR signature in master * Change FastConfig ncol to int32_t. * Removed profiling folder * fix doxygen typo include/LightGBM/c_api.h Co-authored-by:

* [swig] Fix SWIG methods that return char** with StringArray. + [new] Add StringArray class to manage and manipulate arrays of fixed-length strings: This class is now used to wrap any char** parameters, manage memory and manipulate the strings. Such class is defined at swig/StringArray.hpp and wrapped in StringArray.i. + [API+fix] Wrap LGBM_BoosterGetFeatureNames it resulted in segfault before: Added wrapper LGBM_BoosterGetFeatureNamesSWIG(BoosterHandle) that only receives the booster handle and figures how much memory to allocate for strings and returns a StringArray which can be easily converted to String[]. + [API+safety] For consistency, LGBM_BoosterGetEvalNamesSWIG was wrapped as well: * Refactor to detect any kind of errors and removed all the parameters besides the BoosterHandle (much simpler API to use in Java). * No assumptions are made about the required string space necessary (128 before). * The amount of required string memory is computed internally + [safety] No possibility of undefined behaviour The two methods wrapped above now compute the necessary string storage space prior to allocation, as the low-level C API calls would crash the process irreversibly if they write more memory than which is passed to them. * Changes to C API and wrappers support char** To support the latest SWIG changes that enable proper char** return support that is safe, the C API was changed. The respecive wrappers in R and Python were changed too. * Cleanup indentation in new lightgbm_R.cpp code * Adress review code-style comments. * Update swig/StringArray.hpp Co-Authored-By:
