If one of several alternatives configurations are required for
an Erlang module to compile, but none are available, it would
be useful to give a nice error message. For example:
-ifdef(CONFIG_A).
%% Some code if A is true.
-else.
-ifdef(CONFIG_B).
%% Some code if B is true.
-else.
-error("Neither CONFIG_A nor CONFIG_B are available").
-endif.
-endif.
If neither CONFIG_A nor CONFIG_B are defined, the error message
will be:
module.erl:10: -error("Neither CONFIG_A nor CONFIG_B are available").
That is basically the same behavior as for the #error directive in
GCC.
For symmetry with the -error directive, add the -warning
directive to generate a compiler warning. For example:
-ifdef(HAVE_COOL_FEATURE).
%% Code if we have Cool Feature.
-else.
%% Inefficient fallback code.
-warning("Using inefficient fallback").
-endif.
If HAVE_COOL_FEATURE is not defined, the warning message will
be:
module.erl:8: Warning: -warning("Using inefficient fallback").
That is basically the same behavior as for the #warning directive
in GCC.

scan_include_lib/4 uses a helper function find_lib_dir/1, which has a
strange interface. It takes a string and returns a tuple. The caller
must match the tuple and call fname_join/1 to obtain the desired
result. I assume that the strange interface was not noticed because
the function is only used in one place.
Replace the find_lib_dir/1 with a new expand_lib_dir/1 function which
does the entire job in one go. The new function is much easier to
reuse in other places, which we might want to do in a future commit.

If an on_load function had not yet returned, the code server
would only correctly handle calls to code:ensure_loaded/1. That
is, each process that called code:ensured_loaded/1 for the
module in question would be suspended until the on_load function
had returned.
The code server handled calls to code:load_binary/1, code:load_file/1,
and code:load_abs/1 in the same way as for code:ensure_loaded/1.
That means that if call to one those functions attempted to load
*different* code for the module, that code would not get loaded.
Note that code:finish_loading/1 (code:atomic_load/1) will still return
{error,pending_on_load} if there is a pending on_load function for one
of the modules that are about to be loaded. The reason is that
code:finish_loading/1 is meant to either succeed directly, or fail
quickly if there is any problem.

For historical reasons, the second argument in handle_call/3 is
{Pid,Tag}. The tag is always 'call' and is never used.
|
|
Load the module as old code; swap old and new code if the
-on_load function succeeds. That way, a failed update attempt
for a module that has an -on_load function will preserve the
previous version of the code.
