Subject: supervisor doesn't like abstract modules
Message-ID: <425690F5.8030802@cisco.com>


Starting a child using a module instance as the module fails:

** exited: {{nocatch,{error,{invalid_mfa,
                                 {{foo,bar,baz},
                                  start_link,
                                  [one,two,three]}}}}

Turns out there are some checks in supervisor.erl that expect a module to be an atom:

validFunc({M, F, A}) when atom(M), atom(F), list(A) -> true;
validFunc(Func)                                 -> throw({invalid_mfa, Func}).


and

validMods(dynamic) -> true;
validMods(Mods) when list(Mods) ->
     lists:foreach(fun(Mod) ->
             if
             atom(Mod) -> ok;
             true -> throw({invalid_module, Mod})
             end
           end,
           Mods);
validMods(Mods) -> throw({invalid_modules, Mods}).


I changed them to the following and all is well (so far):

validMods(dynamic) -> true;
validMods(Mods) when list(Mods) -> true;
validMods(Mods) -> throw({invalid_modules, Mods}).

validFunc({M, F, A}) when atom(F), list(A) -> true;
validFunc(Func)                                 -> throw({invalid_mfa, Func}).


Mark.

Subject: Emacs support: erlang-man-module brings up the wrong man file
Message-ID: <e3fb311d0504060140325097a8@mail.gmail.com>

If I invoke erlang-man-module with the module name "file" then for me it 
brings up the CosFileTransfer_File(3) manual page.

In the function erlang-man-module the pattern for matching the relevant man 
file is constructed like this

(pat (concat "\\b" (regexp-quote module) "\\.[^.]$"))

thiis is faulty, because \b matches the beginning of a word, but the 
character '_' is not a word constituent in Erlang mode, so it matches 
CosFileTransfer_File too.

The simplest fix is to change \b to /, so that file name part after the 
slash is matched:

(pat (concat "/" (regexp-quote module) "\\.[^.]$"))

After installation, Erlang is added to the "uninstall programs" list
*twice*.  I've tried this on two different machines, including a brand new
one that never had Erlang on it before.
