From f7717260d3146cd1136f994193b8c6d659965706 Mon Sep 17 00:00:00 2001 From: Eric Curtin Date: Mon, 11 Nov 2024 23:21:58 +0000 Subject: [PATCH] Refactor: Replace manual memory management with smart pointers Replaced all `malloc`/`free` calls with `std::unique_ptr` to leverage RAII for memory management. Used custom deleters where needed to handle specific free functions, such as `stbi_image_free` and `free_sd_ctx`. Simplified resource cleanup by removing explicit `free` calls, reducing the risk of memory leaks and improving code readability. Adjusted function calls to align with smart pointer usage, ensuring compatibility and preventing raw pointer access Signed-off-by: Eric Curtin --- CMakeLists.txt | 2 +- examples/cli/main.cpp | 261 ++++++++++++++---------------------------- 2 files changed, 87 insertions(+), 176 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index c993e7c9..59d13e1c 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -119,7 +119,7 @@ add_subdirectory(thirdparty) target_link_libraries(${SD_LIB} PUBLIC ggml zip) target_include_directories(${SD_LIB} PUBLIC . thirdparty) -target_compile_features(${SD_LIB} PUBLIC cxx_std_11) +target_compile_features(${SD_LIB} PUBLIC cxx_std_14) if (SD_BUILD_EXAMPLES) diff --git a/examples/cli/main.cpp b/examples/cli/main.cpp index f1bdc698..4719a067 100644 --- a/examples/cli/main.cpp +++ b/examples/cli/main.cpp @@ -160,7 +160,7 @@ void print_params(SDParams params) { printf(" sample_steps: %d\n", params.sample_steps); printf(" strength(img2img): %.2f\n", params.strength); printf(" rng: %s\n", rng_type_to_str[params.rng_type]); - printf(" seed: %ld\n", params.seed); + printf(" seed: %lld\n", params.seed); printf(" batch_count: %d\n", params.batch_count); printf(" vae_tiling: %s\n", params.vae_tiling ?
