2018-07-13erts: Fix bug where break would not trigger on windowsLukas Larsson
This bug was introduced in 988f5f5e8061ce2. The aux_thread needs to be poked as it is the thread that handles all break actions.

2018-07-13Fix a rare crash when matching on literal mapsJohn Högberg
When matching on a literal map, the map is placed into the general scratch register first. This is fine in isolation, but when the key to be matched was in a Y register it would also be placed in the scratch register, overwriting the map and crashing the emulator.

2018-07-12erts: Fix bug in crash dump generationSverker Eriksson
Symptom: emulator core dumps during crash dump generation. Problem: erts_dump_lit_areas did not grow correctly to always be equal or larger than number of loaded modules. The comment about twice the size to include both curr and old did not seem right. The beam_ranges structure contains *all* loaded module instances until they are removed when purged.

2018-07-03Use fallback pollset for stdin and friends when using kqueueJohn Högberg
This is a hack to make the "noshell" option work; kqueue can poll these fds but will not report EV_EOF. This may be common to all all pipes but we have no way to tell whether an fd is a pipe or not.

2018-06-28Fix a race condition when generating async operation idsJohn Högberg
The counter used for generating async operation ids was a plain int shared between all ports, which was incorrect but mostly worked fine since the ids only had to be unique on a per-port basis. However, some compilers (notably GCC 8.1.1) generated code that assumed that this value didn't change between reads. Using a shortened version of enq_async_w_tmo as an example: int id = async_ref++; op->id = id; //A return id; //B In GCC 7 and earlier, `async_ref` would be read once and assigned to `id` before being incremented, which kept the values at A and B consistent. In GCC 8, `async_ref` was read when assigned at A and read again at B, and then incremented, which made them inconsistent if we raced with another port. This commit fixes the issue by removing `async_ref` altogether and replacing it with a per-port counter which makes it impossible to race with someone else.
2018-06-27Move to a dirty scheduler even when we have pending system tasksJohn Högberg
When a system task was enqueued on a process between being scheduled and the check altered in this commit, we'd run dirty code on a normal scheduler as the RUNNING_SYS flag wasn't set and we wouldn't migrate back. This change migrates us to a dirty scheduler instead, which will immediately bounce us back to a normal scheduler where RUNNING_SYS will be set appropriately. This is caught fairly reliably by process_SUITE:system_task_failed_enqueue on machines with a lot of cores.
