From 9bdb82ef6b3147662ffc6b6435c6bd376c60e19e Mon Sep 17 00:00:00 2001 From: stijn Date: Fri, 22 Jul 2016 11:54:26 +0200 Subject: [PATCH] mpy-cross: Use binary file translation mode for creating mpy files on windows This is a fix for https://github.com/micropython/micropython/issues/2209: by default a file created using open() uses text translation mode so writing \n to it will result in the file having \r\n. This is obviously problematic for binary .mpy files, so provide functions for setting the open mode and use binary mode in mpy-cross' main(). --- mpy-cross/Makefile | 4 ++++ mpy-cross/main.c | 6 ++++++ windows/fmode.c | 49 ++++++++++++++++++++++++++++++++++++++++++++++ windows/fmode.h | 38 +++++++++++++++++++++++++++++++++++ 4 files changed, 97 insertions(+) create mode 100644 windows/fmode.c create mode 100644 windows/fmode.h diff --git a/mpy-cross/Makefile b/mpy-cross/Makefile index 71b78c27c8..ecf26ee317 100644 --- a/mpy-cross/Makefile +++ b/mpy-cross/Makefile @@ -49,6 +49,10 @@ SRC_C = \ main.c \ gccollect.c \ +ifeq ($(OS),Windows_NT) +SRC_C += windows/fmode.c +endif + OBJ = $(PY_O) OBJ += $(addprefix $(BUILD)/, $(SRC_C:.c=.o)) diff --git a/mpy-cross/main.c b/mpy-cross/main.c index 4393d00ff0..5e5bc73304 100644 --- a/mpy-cross/main.c +++ b/mpy-cross/main.c @@ -35,6 +35,9 @@ #include "py/runtime.h" #include "py/gc.h" #include "py/stackctrl.h" +#ifdef _WIN32 +#include "windows/fmode.h" +#endif // Command line options, with their defaults STATIC uint emit_opt = MP_EMIT_OPT_NONE; @@ -185,6 +188,9 @@ MP_NOINLINE int main_(int argc, char **argv) { gc_init(heap, heap + heap_size); mp_init(); +#ifdef _WIN32 + set_fmode_binary(); +#endif mp_obj_list_init(mp_sys_path, 0); mp_obj_list_init(mp_sys_argv, 0); diff --git a/windows/fmode.c b/windows/fmode.c new file mode 100644 index 0000000000..33ba24ed1f --- /dev/null +++ b/windows/fmode.c @@ -0,0 +1,49 @@ +/* + * This file is part of the MicroPython project, http://micropython.org/ + * + * The MIT License (MIT) + * + * Copyright (c) 2013-2016 Damien P.
