2017-11-15erts: Fix NIF debug readonly check of binariesSverker Eriksson
when done by enif_free_env or enif_clear_env. Do check before we free heap fragments.

2017-11-07Ignore empty binaries in enif_inspect_iovecJohn Högberg
2017-11-07Emasculate writable binaries on entering an iovecJohn Högberg
The lack of this caused serious data corruption when a binary was altered after entering the queue. This went unnoticed because it was never used without erlang:iolist_to_iovec, which always emasculates binaries.

when request id is an immediate. Ex: erlang:garbage_collect(P, [{async,Immediate}]). may crash the VM.
2017-10-30erl_process_dump: Don't assume that literals can be foundBjörn Gustavsson
Native code does not register its literals in the code header for the loaded code. Therefore, a literal created by native code can not be found by mark_literal(). Ignore literals that can't be found instead of crashing (the crasdump_viewer will report such literals as incomplete heap data, but will not crash).
2017-10-25Stop assuming that all schedulers are managed when updating msaccJohn Högberg
This fixes statistics_SUITE:msacc when dirty schedulers are used during the test.

2017-10-23erts: Fix so that bind correct schedulersLukas Larsson
When the cpu ids and scheduler ids don't match, the end schedulers could end up not being bound when they should be. example: > taskset -c 1-3 erl +S 4 +sbts > erlang:system_info(scheduler_bindings). {1,2,3,unbound} This fix makes it so that all cores are used to bind schedulers.

2017-10-18Don't dump literal areas that are not referenced at allBjörn Gustavsson
2017-10-18Dump literals separately to avoid incomplete heap dataBjörn Gustavsson
When a literal was used from several processes, the literal would be dumped in only one of the processes. The other processes that referenced the literals would have incomplete heap data.
2017-10-18Implement dumping of maps in crash dumpsBjörn Gustavsson
Maps would be dumped as the atom 'undefined', which is not very informative.
2017-10-18Buffer writing of crash dumpsBjörn Gustavsson
Writing of crash dumps were done using unbuffered IO. This is slow since many small writes are done. Use a FILE* with an allocated buffer to obtain buffered IO. I wrote a small test program that created 50000 binaries of 200 bytes each and then created a crash dump. The crash dumping was an order of magnitude faster with buffered IO than without.

2017-10-09erts: Fix caller trace for apply bifsLukas Larsson
Bifs that are called through the export entry using i_call_last could have their cp set to return_trace, just like any other call. So we have to unwind the trace stack to get the correct cp. Not doing this creates a lot of issues for fprof.

2017-10-02erts: Fix bug when detecting bad dist messageSverker Eriksson
We can't just leave it in queue with dist_ext=NULL. Two symptoms seen: 1. 'receive' trying to deref dist_ext as NULL. 2. GC think it's a term and put THE_NON_VALUE in root set.

2017-09-22Correctly append sub-binaries in iolist_to_iovecJohn Högberg
The byte_offset of sub-binaries wasn't taken into account for ProcBins, subtly ruining the results. The test suite didn't catch it since it didn't check for sub-binaries in particular, and only checked for equality between variations -- not whether the output was equal to the input.

2017-09-13erts: Fix 'on_load' tracing bug for modules with -on_loadSverker Eriksson
Symptom: VM crash when erlang:trace_pattern(on_load, ..) is set and module with -on_load is loaded. Problem: Tracing and -on_load clash in their use of Export.beam[1] Solution: Do not do call set_default_trace_pattern in finish_loading_1 for modules with -on_load. finish_after_on_load_2 will do that anyway.
