2012-01-26call_trace_SUITE: Skip test cases if libraries are native-compiledBjörn Gustavsson
Skip test cases that trace lists or filename if those modules are native-compiled. While we are at it, also eliminate two compilation warnings.

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.

2012-01-11beam_load.c: Don't show unnecessary context in errorsBjörn Gustavsson
For errors that occur after reading the code chunking, saying that the error occurred in the last function in the module and in the instruction int_code_end/0 is just confusing.
2012-01-11beam_load.c: Remove useless call to next_heap_size()Björn Gustavsson
The idea was probably to cause less fragmentation. Even if that would be true, it is irrelevant because the short-lived allocator that is used does not have any problems with fragmentation. In CodeNeed() we will simply double the size of the area used for code instead of using the next heap size.
2012-01-11beam_load.c: apply/2 does not need a special caseBjörn Gustavsson
It is wrongly assumed in the BEAM loader that apply/2 is a BIF and must be treated specially. Also make it clearer in ops.tab that apply/3 is a BIF, but apply/2 is not.

2012-01-04Fix returned error from gen_tcp:accept/1,2 when running out of portsPer Hedeland
The {error, enfile} return value is badly misleading and confusing for this case, since the Posix ENFILE errno value has a well-defined meaning that has nothing to do with Erlang ports. The fix changes the return value to {error, system_limit}, which is consistent with e.g. various file(3) functions. inet:format_error/1 has also been updated to support system_limit in the same manner as file:format_error/1.

2011-12-27Include wakeup pipe in /dev/poll poll-set also on non-SMPRickard Green
I/O events could potentially be delayed for ever when enabling kernel-poll on a non-SMP runtime system executing on Solaris. When also combined with async-threads the runtime system hung before completing the boot phase. This bug was introduced in erts-5.9/OTP-R15B.

2011-12-20Remove bad assertRickard Green
It is possible also in non-SMP case: 1. The process receives an exit signal and is set in status exiting and inserted into the run queue. 2. The distribution port exits before the process has been selected for execution and cannot remove the link half on the process since it is in status exiting. 3. Process is selected for execution and when removing this link half the distribution channel is gone!
