* 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.

2014-03-14erts: Add distribution capability flag for maps DFLAG_MAP_TAGSverker Eriksson
This is just a preparation to allow detection of older nodes that do not understand maps (R16 and older).
2014-03-14erts: Change external format for mapsSverker Eriksson
to be: 116,Arity, K1,V1,K2,V2,...,Kn,Vn instead of: 116,Arity, K1,K2,...,Kn, V1,V2,....,Vn We think this will be better for future internal map structures like HAMT. Would be bad if we need to iterate twice over HAMT in term_to_binary, one for keys and one for values.

The comment in the code state that the tree is traversed to the left, when in fact it is traversed to the right.

2014-02-28hipe: Break apart hipe_bif:make_fe/3 into two BIFsBjörn Gustavsson
This commit is a preparation for eliminating a race condition loading the native code for modules whose BEAM code has already been loaded. Here we introduce two new BIFs so that looking up a fun entry is separate from setting the native address in the fun entry.
2014-02-27erts: Fix Map cmp exact equal of an empty mapBjörn-Egil Dahlberg
The expression, #{} =:= M where M was any Map, would always result in 'true'. This commit fixes this issue by first comparing sizes for both terms and then checking for size zero.

2014-02-24erts: Fix unix efile assertLukas Larsson
If writev return an error (eg ENOSPC) we do not want to abort here but instead propagate upwards into erlang.

2014-02-24erts: Fix sys_msg_dispatcher assertLukas Larsson
Schedulers is too restrictive. Managed threads should be able to clean this up.
2014-02-24ose: Thread priorities configurable from lmconfLukas Larsson
The pattern used for getting the priority from the lmconf is based on the name of the process created. The pattern is: ERTS_%%PROCESS_NAME%%_PRIO with the %%PROCESS_NAME%% replaced by the prefix of the process the priority applies to. eg: ERTS_SCHEDULER_PRIO=24 applies to processes with name SCHEDULER_1, SCHEDULER_2 etc.
2014-02-24ose: Cleanup POLL_SCHED_1 codeLukas Larsson
Now schedulers 2..N make sure to wake sched 1 if they find that all io has been consumed and sched 1 is sleeping. Before sched 1 was spinning in sys_schedule waiting for sched 2..N to finish consuming io jobs
2014-02-24ose: Added Enea copyright header to lcf files.Robert Paal
Also removed softkernel lcf files.
2014-02-24ose: Eliminating delays when trying to open filesRobert Paal
When opening filers on not mounted volumes the default timeout on OSE is quite big and since at startup we load something like 20 beam files this slows down startup by as much as 50 seconds.
2014-02-24ose: Update ddll interface after rebase to 17.0-rc1Lukas Larsson
Also deleted all the copy-paste stuff
2014-02-24ose: Add fair scheduling yieldsLukas Larsson
This is needed on OSs that do not do round robin scheduling of threads.
2014-02-24ose: Port run_erl and to_erlLukas Larsson
2014-02-24ose: Rewrite resolve_signal API for ose driversLukas Larsson
This new API has less impact on the check_io code and also removes the callback from ErlDrvEntry. The downside is that you have to give the resolve function when creating each event. Also the mode if the resolve was removed as this mimics the win32 code and decreases complexity.
2014-02-24ose: Fix starting with pm_createLukas Larsson
For some reason starting with pm_create offsets the input argument list by one, so we have to adjust them before calling erl_start.

2014-02-24ose: OSE port related cleanup and fixesJonas Karlsson
Some OSE cross-chains have problems with system includes being used, so for atleast OSE specific parts we use "" instead of <>.

2014-02-24erts: configure number of write_concurrency locksLukas Larsson
Make it possible to change the number of write_concurrency locks to use. This is usefull to change when you for some reason want to use more/less locks per write_concurrency ets table. eg. OSs with a limit on how many mutexes can exist at once.
