Kinda related to this old thread https://groups.google.com/forum/#!searchin/v8-users/isolate$20memory|sort:date/v8-users/C_CzX8nSbDU/c4FR8-j6BQAJ
Basically, I'd imagine if I instantiate an isolate and immediately "Dispose" it inside a loop, all memory used by the isolated should be released therefore the loop could go on forever. In reality however, doing this would consume all available memories and doesn't seem to release any memory back to the os at all. It is not a "leak" in the sense that it can be caught by valgrind, it appears something is actually hogging the memory. I am really curious of what is holding onto the memory. I really hope I am just missing something obvious and any help is appreciated. I test the following code on a MBP #include "v8/include/v8.h" #include "v8/include/libplatform/libplatform.h" int main(int argc, char* argv[]) { v8::V8::InitializeICUDefaultLocation(V8_LIB_FULL_PATH); v8::V8::InitializeExternalStartupData(V8_LIB_FULL_PATH); std::unique_ptr<v8::Platform> platform = v8::platform::NewDefaultPlatform(); v8::V8::InitializePlatform(platform.get()); v8::V8::Initialize(); for (auto i = 0; i < 1000000000; ++i) { v8::Isolate::CreateParams create_params; create_params.array_buffer_allocator = v8::ArrayBuffer::Allocator::NewDefaultAllocator(); v8::Isolate* isolate = v8::Isolate::New(create_params); isolate->Dispose(); delete create_params.array_buffer_allocator; } v8::V8::Dispose(); v8::V8::ShutdownPlatform(); } It will run until all memory is gone and macOS will just be unresponsive. I was using v8 version 6.5 and with the following build args is_debug = false target_cpu = "x64" use_drfuzz = false use_libfuzzer = false v8_enable_test_features = "" v8_experimental_extra_library_files = [] v8_extra_library_files = [] symbol_level = 1 is_component_build = false use_sysroot = false use_glib = false use_custom_libcxx = false use_custom_libcxx_for_host = false v8_enable_i18n_support = false icu_use_data_file = false v8_static_library = true v8_enable_gdbjit = false Thanks -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
