2013-02-09Fix unsafe optimization of funsBjörn Gustavsson
Commits 53bd4974a101 and 726f6e4c7afe simplified the handling of match_fail (used to generated exceptions such as 'function_clause') by first rewriting them to a call to erlang/error{1,2} and later rewriting them to specialized BEAM instructions (to reduce the code size). There was one flaw, though, which only was exposed when more aggressive optimizations were added in c3b60f86c622. Here is an example to explain it: t(V) -> fun(get) -> V end. The following BEAM code will be initially generated for the fun: {function, '-t/1-fun-0-', 2, 5}. {label,1}. {line,[{location,"t.erl",5}]}. {func_info,{atom,t},{atom,'-t/1-fun-0-'},2}. {label,2}. {test,is_eq_exact,{f,2},[{x,0},{atom,get}]}. {move,{x,1},{x,0}}. return. {label,2}. {test_heap,2,1}. {put_list,{x,0},nil,{x,1}}. {move,{atom,function_clause},{x,0}}. {line,[{location,"t.erl",5}]}. {call_ext_only,2,{extfunc,erlang,error,2}}. Translating back to Erlang code, that would be roughly: '-t/1-fun-0-'(get, V) -> V; '-t/1-fun-0-'(Arg1, _) -> erlang:error(function_clause, [Arg1]). Note that the second argument (the free variable V) is not included in the call to erlang:error/2. The beam_except pass will simplify the code to: {function, '-t/1-fun-0-', 2, 8}. {label,1}. {line,[{location,"t.erl",5}]}. {func_info,{atom,t},{atom,'-t/1-fun-0-'},2}. {label,2}. {test,is_eq_exact,{f,1},[{x,0},{atom,get}]}. {move,{x,1},{x,0}}. return. The code has been shortened by jumping to the func_info/3 instruction. Translating back to Erlang: '-t/1-fun-0-'(get, V) -> V; '-t/1-fun-0-'(Arg1, Arg2) -> erlang:error(function_clause, [Arg1,Arg2]). it is clear that both arguments are now included in the 'function_clause' exception, even though the initially generated code only included the first argument. That is no problem in this particular case, but for some more complex funs, optimizing the first version based on variable usage could make the second version unsafe. I rejected the following potential solutions: - Including the free arguments in the call to erlang:error/2: '-t/1-fun-0-'(get, V) -> V; '-t/1-fun-0-'(Arg1, Arg2) -> erlang:error(function_clause, [Arg1,Arg2]). Unfortunately, that is tricky. The free variables are only known after the second pass in v3_kernel when variable usage has been calculated. We would need to add a third pass (only for funs) that would the free arguments to the second argument for erlang:error/2 *and* update the variable usage information. - Calling beam_except earlier, from within beam_block before any optimizations based on variable usages are done. But means that the problem could reappear in some other form in the future when other updates are done to the code generator and/or optimization passes. The solution I have chosen is to modify beam_except to only replace a call to erlang:error(function_class, Args) if the length of Args is the same as the arity in the func_info/3 instruction. The code will be slightly larger. Also, the free variables for funs and list comprehensions will no longer be included in the function_clause exception (that could be less confusing, but it also means less information during debugging).

2013-02-06erts: Increase length of well formed header names from {packet,http}Sverker Eriksson
To ease matching of unrecognized header field names we convert them from case insensitive to the format Sec-Websocket-Version with capital letters only first and after hyphens. Earlier only header names up to 20 characters were converted to this format due to internal buffer limitation. Raising this limit to 50 is a pragmatic solution for existing long header names such as Sec-Websocket-Version, while valid header names longer than 50 characters are not very probable.

2013-02-06beam_validator: Eliminate dialyzer warnings for unmatched returnsBjörn Gustavsson
The assert_fls/2 and assert_type/3 functions both return the Vst passed to them, but all callers ignore the return value. Given the name of the functions, they are not expected to return anything. Make it so by changing the return value to 'ok'. There are two calls to bsm_get_context/2 used only to validate that the match context is valid. Call bsm_validate_context/2 instead. In bsm_validate_context/2, explicitly match the return value of bsm_get_context/2 to '_' to make it clear that it is not used.
