* bjorn/kernel/on_load-bug/OTP-9875: Fix on_load handling in modules loaded by code:load_binary/3
2012-01-24beam_load.c: Allow stubs for BIFsBjörn Gustavsson
We want to be able to write type specifications for BIFs in the same way as for any other function. Currently, the type for BIFs need to be described in erl_bif_types. To avoid extending the compiler and Dialyzer with special directives for providing specifications for BIFs, we have decided to let the loader accept a local definition for a function which exists as a BIF. As an example, here is how a stub for lists:reverse/2 can be defined: -export([reverse/2]). -spec reverse([term()], term()) -> [term()]. reverse(_, _) -> erlang:nif_error(undef). Essentially, the loader will discard the local definition of reverse/2. Other functions in the same module must *not* do local calls to a BIF stub. If a local call to a BIF is found, the loader will refuse to load the module. That is, the following call is not allowed: reverse(List) -> reverse(List, []). but the following is: reverse(List) -> ?MODULE:reverse(List, []). A few words about the implementation. It turns out to be too complicated to actually discard the BIF stubs. Although it would be possibly with some jiggery pokery in ops.tab, the code would be difficult to maintain and it could slow down loading of modules that don't define BIFs (which are almost all modules). Therefore, the stub functions are kept in the loaded code, but their names in the func_info instruction are invalidated so that module_info(functions) can filter them out.

* maint: Correct two contracts in gen_sctp.erl
2012-01-23Fix on_load handling in modules loaded by code:load_binary/3Björn Gustavsson
In "13.4 Running a function when a module is loaded" in the Reference Manual, it is said that: A process that calls any function in a module whose on_load function has not yet returned will be suspended until the on_load function has returned. That did not work if the module was loaded using code:load_binary/3. Instead, the callers would get an 'undef' exception.

binary should be binary().

2011-12-21prim_file_SUITE: large_file success depends on wordsizeRaimo Niskanen
Check VM wordsize to see if a driver command with data larger than 32-bit size is supposed to succeed. On wordsize 4 machines (32-bit) {error,einval} is expected since the total size passed to a driver can not exceed sizeof(ErlDrvSizeT).
