From d2b1ddd1a3bc8f3d91cb931b4e08b35c946a4af8 Mon Sep 17 00:00:00 2001 From: Matt Corallo Date: Fri, 15 Apr 2022 16:11:46 +0000 Subject: [PATCH] Convert primitives before passing to host language This resolves an issue where we map unsigned primitives to their signed variants, and occasionally pass the unsigned variant (which is outside the bounds of the signed variant) to the host language. In Java this can cause a panic as the VM sees an int outside the range of a short (for example with network ports). --- gen_type_mapping.py | 14 +++++++++++--- 1 file changed, 11 insertions(+), 3 deletions(-) diff --git a/gen_type_mapping.py b/gen_type_mapping.py index ad7d46fc..9aeee615 100644 --- a/gen_type_mapping.py +++ b/gen_type_mapping.py @@ -260,11 +260,19 @@ class TypeMappingGenerator: return ConvInfo(ty_info = ty_info, arg_name = ty_info.var_name, arg_conv = None, arg_conv_name = "arg", arg_conv_cleanup = None, ret_conv = None, ret_conv_name = None, to_hu_conv = "TODO 8", to_hu_conv_name = None, from_hu_conv = None) - elif ty_info.is_native_primitive: + elif ty_info.is_native_primitive and ty_info.c_ty != "void": assert not is_nullable return ConvInfo(ty_info = ty_info, arg_name = ty_info.var_name, - arg_conv = None, arg_conv_name = ty_info.var_name, arg_conv_cleanup = None, - ret_conv = None, ret_conv_name = None, to_hu_conv = None, to_hu_conv_name = None, from_hu_conv = None) + arg_conv = None, arg_conv_name = ty_info.var_name, arg_conv_cleanup = None, + ret_conv = (ty_info.c_ty + " " + ty_info.var_name + "_conv = ", ";"), ret_conv_name = ty_info.var_name + "_conv", + to_hu_conv = None, to_hu_conv_name = None, from_hu_conv = None) + elif ty_info.c_ty == "void": + assert ty_info.is_native_primitive + assert not is_nullable + return ConvInfo(ty_info = ty_info, arg_name = ty_info.var_name, + arg_conv = None, arg_conv_name = ty_info.var_name, arg_conv_cleanup = None, + ret_conv = None, ret_conv_name = ty_info.var_name, + to_hu_conv = None, to_hu_conv_name = None, from_hu_conv = None) else: if ty_info.var_name == "": ty_info.var_name = "ret" -- 2.39.5
