when done by enif_free_env or enif_clear_env. Do check before we free heap fragments.
2017-11-13Remove invalid EINTR loop around close(2)John Högberg
Retrying close(2) on anything other than HP-UX is likely to close something entirely different. POSIX says that the state of the file descriptor is unspecified, and Linux/BSD guarantee that it's closed on return.

2017-11-09Fix deflateParams on zlib 1.2.11John Högberg
1.2.11 started bailing when avail_out==0 regardless of whether there's anything to flush or not, and there's no point in adapting the old method since it was vulnerable to bugs in other zlib versions which updated the deflate parameters even on failure. The api_deflateParams test has been expanded accordingly, and two white-box cases in zip_usage has been updated to make fewer assumptions about the output; the validity of the compressed data is what matters, not whether it's exactly the same as the test vector.

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.
2017-11-06erts: Fix bug in systask schedulingSverker Eriksson
when request id is an immediate. Ex: erlang:garbage_collect(P, [{async,Immediate}]). may crash the VM.
2017-11-05fix output formatting in hipe_bifs:show_heap/1Mikael Pettersson
When the code switches from printf() to erts_printf() the output becomes garbled. Fixed by fflush()ing stdout first. Fixed formatting of the "H E A P" banner for 64-bit systems.

by introducing new primop 'is_unicode' with no exception (ab)use and no GC. Replaces bs_validate_unicode which is kept for backward compat for now.
2017-11-03Prevent hipe_bs_validate_unicode from doing GCSverker Eriksson
Fix for x86_64 only. The calling native code can not handle a GC as it has a raw pointer where to write the binary data. If a GC happens the data (utf32) will be written to the old deallocated heap.

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).

2017-10-23erts: 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.

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.
