2014-04-29Fix race between ETS table deletion and unfixationSverker Eriksson
Symptom: VM crash running mnesia_SUITE Scenario: Process A terminates while still having fixed table T and process B "at the same time" deletes table T with ets:delete/1 or by terminating. Problem: A table scheduled for deallocation do only have a valid 'common' part. The unfix-table-at-process-exit code tried to read the hash-specific part of such a table. Solution: Must back off if DB_DELETE flag is set. Since: R16B

2014-03-28prevent NIF purge during dirty NIF executionSteve Vinoski
Reference-count the NIF before and after invoking a NIF on dirty schedulers to prevent having the NIF purged during the call.
2014-03-28fix dirty NIF invalid memory readSteve Vinoski
Dirty NIF support used an Export structure to facilitate calls to dirty NIFs and finalizers, but Export isn't large enough to hold all necessary data. This was causing an invalid memory read in beam_emu.c past the end of the Export object. Add a local extended Export struct to erl_nif.c that can hold all the necessary data.

2014-03-27erts: Fix bug of scheduling a suspended processSverker Eriksson
This is a race that can cause RUNNING (instead of RUNNING_SYS) set on a SUSPENDED process. The effect of this race happening is probably quite benign. The bug was discovered by process_SUITE:processes_gc_trap on debug VM crashing on last assert in schedule(): /* Never run a suspended process */ ASSERT(!(ERTS_PSFLG_SUSPENDED & erts_smp_atomic32_read_nob(&p->state)));
2014-03-27erts: Adjust is_external_header() for new map tagSverker Eriksson
to not mistake a map for an external term (pid, port or ref).
2014-03-26Change the subtag used for maps from 0xB to 0xFKostis Sagonas
The subtag chosen for maps breaks crucial assumptions in other parts of the system, in particular the native code generation scheme used in the HiPE compiler. Therefore it is better to use 'the other' unused subtag. The main change here is the use of 0xF subtag for maps instead of 0xB. The rest of the differences are changes to and additions of comments. One more comment from my part. I noticed that the file contains the following two lines: The comment of the second line is most certainly a copy and paste error and should be appropriately fixed by the OTP developers. More importantly, it would be great if that subtag (0x7) turned out to be unused and could be used for maps instead of the 0xF one. This might turn out very handy in the future. I can elaborate on this, if needed.

2014-03-25Fix DTrace/SystemTap-related formattingScott Lystig Fritchie
Thanks to Michał Ptaszek for bringing this embarrassing formatting error to my attention. Many DTrace/SystemTap trace strings are incorrectly truncated at 4/8 bytes, depending on the CPU word size. This patch expands the work from commit d032e097 by zheng siyao.

* bjorn/erts/fix-lingering-tracer: Teach the call_time trace to notice when the trace dies (non-SMP system)
2014-03-20Teach the call_time trace to notice when the trace dies (non-SMP system)Björn Gustavsson
The call_time trace is a special kind of tracing that requires a tracer process just like ordinary call trace, but it never actually sends anything to the tracer. It merely use the existence of a trace process (and call trace flags) as an indication that call_time tracing is active for the process. If the tracer dies in a non-SMP run-time system, processes with call_time tracing would not notice that the tracer had died. Furthermore, if the set_on_spawn flag was active, the dead tracer could be propagaged to newly spawned processes. Before accumulating trace information in a non-SMP system, always validate the tracer process. (In an SMP system, a reference to a dead tracer will be cleared away each time a process is scheduled.) While we could put all of the new code beam_bp.c, we have chosen to make a function call from beam_bp.c to a function in erl_trace.c for clarity's sake and to ease further maintenance. In the future, we might want to handle tracing in more similar ways in the SMP and non-SMP system.
