2016-09-22file_SUITE: Test file:write_file/3Björn Gustavsson
Extend file_SUITE:read_write_file/1 to test file:write_file/3 which was not tested at all. While we are it, remove the superfluous roundtrips tests of term_to_binary/1 and binary_to_term/1. Those BIFs are tested in detail in other test suites (for example, binary_SUITE in emulator_test).

2016-09-19Use more correct delimiters for erl_nif.h includeTuncer Ayaz
Anywhere but the beam sources we shouldn't #include "erl_nif.h", because what "erl_nif.h" does is: (1) fail to find it outside of -I dirs, (2) then treat it as if it was written like <erl_nif.h>. Using <erl_nif.h> skips (1). More information can be found in 6.10.2 of the C standard. Because the examples use "erl_nif.h", NIF projects in the Erlang ecosystem copy this verbatim and make the same mistake.

2016-09-14Don't leak old code when loading a modules with an on_load functionBjörn Gustavsson
Normally, calling code:delete/1 before re-loading the code for a module is unnecessary but causes no problem. But there will be be problems if the new code has an on_load function. Code with an on_load function will always be loaded as old code to allowed it to be easily purged if the on_load function would fail. If the on_load function succeeds, the old and current code will be swapped. So in the scenario where code:delete/1 has been called explicitly, there is old code but no current code. Loading code with an on_load function will cause the reference to the old code to be overwritten. That will at best cause a memory leak, and at worst an emulator crash (especially if NIFs are involved). To avoid that situation, we will put the code with the on_load function in a special, third slot in Module. ERL-240

When printing the error term from on_load, insert a newline because the term is never short and will produce hard to read/copy output that is just hanging off to the right.

2016-08-29Fix purge of codeRickard Green
Ensure that we cannot get any dangling pointers into code that has been purged. This is done by a two phase purge. At first phase all fun entries pointing into the code to purge are marked for purge. All processes trying to call these funs will be suspended and by this we avoid getting new direct references into the code. When all processes has been checked, these processes are resumed. The new purge strategy now also completely ignore the existence of indirect references to the code (funs). If such exist, they will cause bad fun exceptions to the caller, but will not prevent a soft purge or cause a kill of a process having such live references during a hard purge. This since it is impossible to give any guarantees that no processes in the system have such indirect references. Even when the system is completely clean from such references, new ones can appear via distribution and/or disk.

2016-08-12erts/kernel: Fix code loading deadlock during init:stopLukas Larsson
When init:stop is called it walks the application hierarchy and terminates each process. Some of these processes may do something while terminating and sometimes that something needs to load some new code in order to work. When this happens the code_server could just be in the process of terminating or the erl_prim_loader could be active. In both these cases the request to load the new code would cause a deadlock in the termination of the system. This commit fixes this by init rejecting attempts to load new code when init:stop has been called and fixing a termination race in the code_server. This however means that the process that tried to do something when told to terminate (for instance logging that it is terminating) will crash instead of loading the code.
