Putenv and getenv needs to convert to the proper environment
strings in Unicode depending on platform and user settings for filename
encoding. Also erlexec needs to pass environment strings in an appropriate
way for kernel to pick up. All environment strings on the command
line, as well as home directory, is now passed in UTF8 on windows
and in whatever encoding you have on Unix, kernel tries to convert all
parameters and environments from UTF8 before making strings.

* rickard/proc-lock-queues/OTP-10163:
Use static allocation of process lock queues
|
|
* rickard/dealloc/OTP-10162:
Improve the enqueue operation of delayed dealloc
Implement delayed aux work wake up
|
|
By using statically allocated lock queues there is no longer
any need for locking corresponding pix lock when process
locks have been transferred after a wait. This costs us 3 words
extra in process structure, but improves performance during
contention.
|
|
The enqueue operation have been re-written to behave better
during heavy contention by spreading writes over multiple
locations. This enqueue operation also take advantage of the
delayed aux work wake up functionality and can by this omit
one memory barrier.
|
|
By using a delayed aux work wake up approach, a memory barrier
can be omitted in the delayed dealloc enqueue operation. The
amount of operations, on the potentially contended, wake up
structure is also reduced.

erts/emulator/hipe/hipe_arm.c started out as a clone of hipe_ppc.c,
with #ifdefs to select ARM-specific code. Somehow those #ifdefs
never got cleaned out, resulting in fairly ugly-looking code.
This eliminates the #ifdefs, deletes dead PowerPC-specific code, and
keeps only the ARM-specific code. I've verified that the exact same
assembly code is generated for hipe_arm.c before and after this patch
(if you compile without -g, with -g there are unavoidable changes to
the debug data).

* rickard/thr-prgr-use/OTP-10116:
Fix faulty use of thread progress in handle_aux_work()
|
|
As an optimization old thread progress data was kept and used in
handle_aux_work() in erl_process.c. This could cause memory to be
deallocated at a later time than intended, which is quite harmless.
This has, however, now been fixed.

dtrace doesn't print sender pid and receiver pid in message related
probe correctly, it truncates pid string to 7 characters on 64bit
platform(or 3 characters on 32bit platform). The dtrace related code
did not set the string length correctly, it sets the string length to
the length of a pointer rather than the buffer length.

The hybrid heap emulator was last working in the non-SMP R11B
run-time system. When the constant pools were introduced in R12B,
the hybrid heap emulator was not updated to handle them.
At this point, the harm from reduced readability of the code is
greater than any potential usefulness of keeping the code.

Ensure displayed sizes are not negative.

This significantly reduces latency for tcp servers
with high load, as we need not go into poll to get
the next message. Maximum throughput may increase
between 4 to 6 times compared to R15B.

This leak is harmless as the beam process is about to exit anyway.

When spawning OS (unix) processes with erlang:open_port, store the
resulting unix pid so that it can be queried later on using
erlang:port_info/1,2.
