The OSE port is no longer supported and this commit removed it
and any changes related to it. The things that were general
improvements have been left in the code.

Save IO bytes in scheduler specific data

Try write directly to process heap (as before)
if the term is guaranteed not to contain any
big maps that may break the initial size estimation.
|
|
by adding a dynamic heap factory.
"binary_to_term" is now a hybrid solution with both
a call to decoded_size() to calculate needed heap space
AND possible dynamic allocation of more heap space
if needed for big maps.
The heap size returned from decoded_size() is guaranteed
to be sufficient for all term heap data except for hashmap
nodes. All hashmap nodes are created at the end of dec_term()
by invoking the heap factory interface that may allocate more
heap space on process heap or in fragments.
With this commit it is no longer guaranteed that a message
is confined to only one heap fragment.

The old time API is based on erlang:now/0. The major issue with
erlang:now/0 is that it was intended to be used for so many
unrelated things. This tied these unrelated operations together
and unnecessarily caused performance, scalability as well as
accuracy, and precision issues for operations that do not need
to have such issues. The new API spreads different functionality
over multiple functions in order to improve on this.
The new API consists of a number of new BIFs:
- erlang:convert_time_unit/3
- erlang:monotonic_time/0
- erlang:monotonic_time/1
- erlang:system_time/0
- erlang:system_time/1
- erlang:time_offset/0
- erlang:time_offset/1
- erlang:timestamp/0
- erlang:unique_integer/0
- erlang:unique_integer/1
- os:system_time/0
- os:system_time/1
and a number of extensions of existing BIFs:
- erlang:monitor(time_offset, clock_service)
- erlang:system_flag(time_offset, finalize)
- erlang:system_info(os_monotonic_time_source)
- erlang:system_info(time_offset)
- erlang:system_info(time_warp_mode)
- erlang:system_info(time_correction)
- erlang:system_info(start_time)
See the "Time and Time Correction in Erlang" chapter of the
ERTS User's Guide for more information.

Adding ERTS_SWORD_MAX to a pointer does not work
as a way to disable a bound check.
Remove the hp_end from ErtsHeapFactory as it isn't really used anyway.
|
|
This variable hold the values returned by erlang:port_info/1 and
shouldn't be static.

Fix DTrace/SystemTap-related formatting
|
|
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.

* paulgray/dtrace_snprintf_fix/OTP-11816:
Pass full strings to DTrace probes
|
|
Whenever string is passed as an argument to a DTrace probe, its length
should be properly computed. Until now in order to get length of the
input buffer size_of(char *) was used - which evalutes to 4 or 8
(depending on the architecture). To get a proper length,
size_of(DTRACE_CHARBUF_NAME(buffer_name)) should be used.
|
|
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.
|
|
This simplified debugging on OSE and also limits the number of ppdata
keys that are created when beam is restarted.
