From 6b1d701387077a61dadc929782195a3cbd3867a9 Mon Sep 17 00:00:00 2001 From: Cuong Manh Le Date: Sun, 15 Nov 2020 03:27:15 +0700 Subject: [PATCH] Fix all invalid usages of unsafe.Pointer Most of the invalid usages due to the conversion from uintptr to unsafe.Pointer. In general, unsafe.Pointer(p) where p of type uintptr is considered unsafe. To fix that, use &p instead of p, then introduce another dereference. Example, the invalid usage: *(*int)(unsafe.Pointer(p)) = int(v) wil become: **(**int)(unsafe.Pointer(&p)) = int(v) Closes #53 --- decode.go | 4 +- decode_bool.go | 8 +- decode_compile.go | 24 ++--- decode_interface.go | 30 +++--- decode_map.go | 8 +- decode_ptr.go | 4 +- decode_slice.go | 8 +- decode_string.go | 4 +- decode_unmarshal_json.go | 4 +- decode_unmarshal_text.go | 4 +- encode.go | 2 +- encode_vm.go | 216 ++++++++++++++++++++++----------------- 12 files changed, 173 insertions(+), 143 deletions(-) diff --git a/decode.go b/decode.go index 56b9c24..71c7d1b 100644 --- a/decode.go +++ b/decode.go @@ -85,7 +85,7 @@ func (d *Decoder) decode(src []byte, header *interfaceHeader) error { typeptr := uintptr(unsafe.Pointer(typ)) // noescape trick for header.typ ( reflect.*rtype ) -
