2016-09-29Fix minor soft purge bugRickard Green
A process calling a fun from a module currently being soft-purged could race with failure of the soft purge. When this happened the call triggered loading of the module which erroneously would load new code for the module in the case no new generation was currently loaded.

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

Thread progress leader update did not cache current unmanaged index when waiting for unmanaged threads. This caused erts_thr_progress_unmanaged_delay() to stop working until a new leader took over.
