2014-03-05stdlib: Fix a Dets bug where files were deletedHans Bolinder
Instead of deleting the small file when opening it with dets:open_file/2 an error message is returned, mimicking the behaviour when the file is bigger. open_file/1 has been modified to return the same error message when the file is small as when the file is bigger. Thanks to Hakan Mattson for reporting this bug.

2014-03-05Add types for new HiPE BIFsKostis Sagonas
Commit 81c7db0e247a6ee1b7a5c2764aa9575d7f6fb88a broke apart hipe_bif:make_fe/3 into two BIFs but forgot to properly update the type information about HiPE BIFs in erl_bif_types.erl. This commit fixes this by taking out the types of hipe_bifs:make_fe/3 and adding types for the new BIFs hipe_bifs:get_fe/2 and hipe_bifs:hipe_bifs_set_native_address_in_fe/2.

2014-03-04Introduce compiler option 'nowarn_deprecated_type'Hans Bolinder
The deprecation of the built-in types dict/0 and so on had as side-effect that it was impossible to switch to dict:dict/2 and so on without getting warnings either in the the previous release (R16B) or the current one (17.0). By including the attribute -compile(nowarn_deprecated_type). in an Erlang source file warnings about deprecated types can be avoided in 17.0. The option can also be given as a compiler flag: erlc +nowarn_deprecated_type file.erl

2014-03-03Do not mark all calls to erlang:is_function/2 as safeAnthony Ramine
Calls to erlang:is_function/2 where the second is not a literal nonnegative integer can crash at runtime and thus can't be marked as safe.
2014-03-02Do not mark all calls to erlang:is_record/3 as safeAnthony Ramine
Calls to erlang:is_record/3 where the second and third arguments are not respectively a literal atom and a literal integer can't be transformed to guards and thus are not safe. Reported-by: Ulf Norell

2014-02-28Delay patching of closures to eliminate a race conditionBjörn Gustavsson
The loader of native code tries to avoid race condition by bringing down the system to a single scheduler. Unfortunately, that will not completely avoid race conditions beacuse other processes may still run while the code is being loaded. Therefore, we must still make sure that native code has been fully fixed up before it can be executed. Under unlucky circumstances, it was possible for the global name register process to call a fun in native code before the native code for the fun had been fully fixed up. The run-time system would crash when running the not-fully-fixed-up code. Here is a way to make the bug 100% reproducible. First add this function to the 'global' module: silly_looper(List) -> lists:foreach(fun(E) -> put(any_atom, E) end, List), silly_looper(List). Then insert the following code at the beginning of the init/1 function in the 'global' module: spawn_link(fun() -> silly_looper(lists:seq(1, 100)) end), The run-time system will crash during start up when the native code for the 'global' module is being loaded. What will happen is that lists:foreach/2 (which runs in native code) will call the native code for the fun in silly_looper/1 before the reference to 'any_atom' has been changed from a 0 to the proper tagged atom value. The put/2 BIF will exit when attempting to calculate the hash value for the illegal value 0 (it is not properly tagged). To eliminate this race condition, we must delay patching the native code addresses for a fun into the fun entry until the native code has been fully fixed up. We will use the new BIFs introduced in the previous commit. While we are at it, we will also make sure that we erase any temporary variables in the process dictionary used by the hipe_unified_loader module.
2014-02-28hipe: Break apart hipe_bif:make_fe/3 into two BIFsBjörn Gustavsson
This commit is a preparation for eliminating a race condition loading the native code for modules whose BEAM code has already been loaded. Here we introduce two new BIFs so that looking up a fun entry is separate from setting the native address in the fun entry.
2014-02-27erts: Fix Map cmp exact equal of an empty mapBjörn-Egil Dahlberg
The expression, #{} =:= M where M was any Map, would always result in 'true'. This commit fixes this issue by first comparing sizes for both terms and then checking for size zero.
