[Wxlua-users] wxLua with wxSocket ReadMsg() problem and work around.

[Steve K. <ha...@ya...>]

Hi everyone,

I have problem when using wxSocket in wxLua, ReadMsg
return some garbage at the end of the string. The
senario is:

c. WriteMsg(luastr, luastr:len())
s. ReadMsg(80)  // 80 is assured to be much bigger
than luastr:len() 

If using in C++ (wxWidgets) the buffer returned by
ReadMsg (even the nbytes is much bigger than the len
actually written to socket) is the correct len. Have
looked at the wxWidget source code and verify this.
However if using it in Lua, I get garbage string at
the end.

So I propose to change this line:

lua_pushlstring(L, (const char *)buffer, nbytes);

to 

lua_pushlstring(L, (const char *)buffer,
self->LastCount()); // skieu

in 
wxLua_wxSocketBase_Read(lua_State *L) and
wxLua_wxSocketBase_ReadMsg(lua_State *L)

I am not sure of the side effect of that change but it
worked for me, I never get any garbage since then :-)

Any comment?

Cheers
