From b681cb20ee6bfc31b8ba23ec321140aae6e53e9d Mon Sep 17 00:00:00 2001 From: danpetry Date: Wed, 23 May 2018 14:09:17 +0200 Subject: [PATCH 1/1] Remove dependency on nonexistent RIOT syscalls Os.rename and os.clock, in Lua, now always return an error message. Also, l_randomizePivot, which is used by table.sort, will always supply 0 rather than a pseudorandom number. --- loslib.c | 7 ++----- ltablib.c | 4 +++- 2 files changed, 5 insertions(+), 6 deletions(-) diff --git a/loslib.c b/loslib.c index dd2bb378..f9e5cbd2 100644 --- a/loslib.c +++ b/loslib.c @@ -157,9 +157,7 @@ static int os_remove (lua_State *L) { static int os_rename (lua_State *L) { - const char *fromname = luaL_checkstring(L, 1); - const char *toname = luaL_checkstring(L, 2); - return luaL_fileresult(L, rename(fromname, toname) == 0, NULL); + return luaL_error(L, "This function is not implemented in RIOT yet"); } @@ -181,8 +179,7 @@ static int os_getenv (lua_State *L) { static int os_clock (lua_State *L) { - lua_pushnumber(L, ((lua_Number)clock())/(lua_Number)CLOCKS_PER_SEC); - return 1; + return luaL_error(L, "This function is not implemented in RIOT yet"); } diff --git a/ltablib.c b/ltablib.c index 588bf40d..8895b653 100644 --- a/ltablib.c +++ b/ltablib.c @@ -235,13 +235,15 @@ static int unpack (lua_State *L) { /* type for array indices */ typedef unsigned int IdxT; - /* ** Produce a "random" 'unsigned int' to randomize pivot choice.
