* bjorn/erts/cuddle-with-tests:
time_SUITE: Make consistency/1 work in any timezone
|
|
This merge is actually only some left overs.
The bulk work for hipe-amd64-code-alloc has already been
merge (without ticket number) at 42a1166b47721cd444.

* mikpe/otp-19-erts-integer-truncation-bugs/PR-1045/OTP-13606:
erl_unicode.c: fix integer truncation problems
do not limit heap fragments to 4 giga-words
erts_new_mso_binary(): do not truncate len

The OpenBSD 5.8 gcc compiler emits erroneous code
which results in the re:run function behaving badly,
though strangely enough it does not segfault the vm.
This fix moves code around a bit in order to make gcc
emit correct code.

time_SUITE:consistency/1 would only work in CET, which was
reasonable when the test suites were always run in Stockholm.
Nowadays it is expected that you can run the test suite in any
timezone. Therefore, only make sure that that difference between
localtime/1 and universaltime/1 is "reasonable".

* lukas/trace-fix:
erts: Only allow remove from trace_status callback

|
* rickard/ds-proc-exit/OTP-13123:
Add dirty_heap_access test case
Add dirty_call_while_terminated test case
Move dirty nif test cases into dirty_nif_SUITE
Add better support for communication with a process executing dirty NIF
Remove conditional dirty schedulers API
|
|
Make it so that it is only possible to remove a tracer via
returning remove from an erl_tracer. This limition is put in
place in order to avoid a lot of lock checking and taking
in various places, especially in regards to trace events
happening on dirty schedulers.

The max_heap_size process flag can be used to limit the
growth of a process heap by killing it before it becomes
too large to handle. It is possible to set the maximum
using the `erl +hmax` option, `system_flag(max_heap_size, ...)`,
`spawn_opt(Fun, [{max_heap_size, ...}])` and
`process_flag(max_heap_size, ...)`.
It is possible to configure the behaviour of the process
when the maximum heap size is reached. The process may be
sent an untrappable exit signal with reason kill and/or
send an error_logger message with details on the process
state. A new trace event called gc_max_heap_size is
also triggered for the garbage_collection trace flag
when the heap grows larger than the configured size.
If kill and error_logger are disabled, it is still
possible to see that the maximum has been reached by
doing garbage collection tracing on the process.
The heap size is defined as the sum of the heap memory
that the process is currently using. This includes
all generational heaps, the stack, any messages that
are considered to be part of the heap and any extra
memory the garbage collector may need during collection.
In the current implementation this means that when a process
is set using on_heap message queue data mode, the messages
that are in the internal message queue are counted towards
this value. For off_heap, only matched messages count towards
the size of the heap. For mixed, it depends on race conditions
within the VM whether a message is part of the heap or not.
Below is an example run of the new behaviour:
Eshell V8.0 (abort with ^G)
1> f(P),P = spawn_opt(fun() -> receive ok -> ok end end, [{max_heap_size, 512}]).
<0.60.0>
2> erlang:trace(P, true, [garbage_collection, procs]).
1
3> [P ! lists:duplicate(M,M) || M <- lists:seq(1,15)],ok.
ok
4>

- use Sint for 'left' and Uint for 'pos'
- cost_to_proc(): adjust types, remove unused return value
- copy_utf8_bin(): return Uint
- characters_to_utf8_trap(): remove harmful cast
- unicode_characters_to_binary_2(): correct types in debug code
- erts_convert_filename_to_encoding(): remove useless cast

- struct erl_heap_fragment: use Uint for sizes
- erl_nif.c: use size_t for sizes

'on_load' is a call trace.

This is the easy way out to avoid difficult locking
