check_process_code: Sweep HiPE stack for literals

We have to do an extra check if the return_to trace is enabled here
as it may have been cleared by the bif after the flags where
created by the call_trace.
|
|
Because check_process_code neglected checking the HiPE stack for
references to the literal area, such references would survive the purge
and subsequent deletion of a module and its literal area. These dangling
references would then cause incorrect behaviour or even hard crashes of
the VM.
By simply adding a scan of the HiPE stack to check_process_code and
erts_garbage_collect_literals, this problem is fixed.
In order to support full stack walks without deleting the graylimit
trap, a new stack walking interface function,
nstack_walk_init_sdesc_ignore_trap() was introduced.

This makes the time that the tests execute longer, which means
that on systems with low resolution on timers (e.g. windows)
the test is less likely to fail.
|
|
The granualarity of the windows time sometimes makes timer:tc
return 0 as the time taken for the test. Change this to use
the most common time instead.
|
|
|
|
if node fails to start, just skip testcase
|
|
It has to be possible to send trace messages to a port
from non-schedulers threads (specifically from the
sys_msg_dispatcher).

* kvakvs/erts/monitor_port/OTP-11384:
erts: Add port monitors
|
|
* erlang:monitor/2 with port argument is added, erlang:demonitor, using port task API and avoiding locking;
* port_info and process_info support for monitored ports (with named port monitors support);
* Exit signals contain type 'process' or 'port';
* Propagation of port exit signals;
* Self-cleaning when origin process dies with monitor on;
* 8 test cases + testcase for port driver crashing;
* Documentation for all of the above (monitor, demonitor, port_info and process_info) updated

Replace enif_is_on_dirty_scheduler() with enif_thread_type()
No GC on dirty IO schedulers

From 'com_ericsson_otp' to 'org_erlang_otp'.
This domain name is more suitable.

|
* vinoski/dirty_process_main/OTP-13123:
Add dirty_process_main function
|
|
Dirty schedulers only execute NIFs, so having them execute the full
process_main function isn't necessary. Add dirty_process_main for
dirty schedulers to execute instead.
Add erts_pre_dirty_nif(), called when preparing to execute a dirty
nif.
Add more dirty NIF tests to verify that activities requiring the
process main lock can succeed when the process is executing a dirty
NIF.

Removed in f9cb80861f169743 when changed impl from C to Erlang.
But seems they are needed to keep dialyzer tests happy.
Also improved bif_SUITE:shadow_comments to include all exported
in module erlang, not just the "snifs".
...which detected that apply/2 was missing Shadowed comment as well.

* egil/erts/fix-purge_code-literals:
erts: Refactor ERTS_MSG_COMBINED_HFRAG to heap fragment
erts: Copy literals in messages on module purge
erts: Add testcase for purge of literals
|
|
The extra trace data has been moved to the opts map in order
for the tracer to be able to distinguish inbetween extra
trace data 'undefined' and no extra trace data. In the same
commit all opts associations have been changed so that if
the tracer should not use them, the key is left unassicated
instead of being sent to undefined. This should be give a
small performance gain and also makes the API easier to work
with.
|
|
Specifically t_copy_literals_frags/1 tries to test literals
in message heap fragments.

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.
