From be04820c070d01d7565b936fa14efc2941055e0b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn=20Gustavsson?= Date: Wed, 16 Feb 2011 06:54:15 +0100 Subject: emulator: Add a fourth element in exception stacktraces This commit is a preparation for introducing location information (filename/line number) in stacktraces in exceptions. Currently a stack trace looks like: [{Mod1,Function1,Arity1}, . . . {ModN,FunctionN,ArityN}] Add a forth element to each tuple that can be used indication the filename and line number of the source file: [{Mod1,Function1,Arity1,Location1}, . . . {ModN,FunctionN,ArityN,LocationN}] In this commit, the fourth element will just be an empty list, and we will change all code that look at or manipulate stacktraces. --- lib/stdlib/src/c.erl | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/stdlib/src/c.erl') diff --git a/lib/stdlib/src/c.erl b/lib/stdlib/src/c.erl index febfdd6285..a920921a5e 100644 --- a/lib/stdlib/src/c.erl +++ b/lib/stdlib/src/c.erl @@ -797,7 +797,7 @@ appcall(App, M, F, Args) -> catch error:undef -> case erlang:get_stacktrace() of - [{M,F,Args}|_] -> + [{M,F,Args,_}|_] -> Arity = length(Args), io:format("Call to ~w:~w/~w in application ~w failed.\n", [M,F,Arity,App]); -- cgit v1.2.3
