In commit b67d3e5447f4b2bca3ed92f3db84adb3f79f9b16 (which cleaned up
handling of error reasons), the test of the return value from
beam_make_current_old() in insert_new_code() was not updated, which
meant that it never was true and any number of versions of code could
be loaded for a module.

The second function erts_unblock_fpe is not needed in here.

Bug caused faulty result (big_SUITE:big_float_1)
and an unhandled floating point exception.

Nasty abs bug fixed in VM as well as type errors in allocator debug functions
Still one allocator test that fails, domain knowledge is needed to fix that.

Commit 8781932b3b8769b6f208ac7c00471122ec7dd055 broke
erlang:system_info(system_version) in the non-SMP emulator so
that it would typically dump core.
"rq:%d" was removed from the format string for erts_printf(),
but the corresponding argument in the argument list was not removed,
which ultimately caused "kernel-poll:%s" to be passed an integer
(typically 0).

Deprecate erlang:system_flag/2 arguments scheduler_bind_type and cpu_topology

Remove common run-queue in SMP case
Fix scheduler suspend bug
Conflicts:

The use of erlang:system_flag(scheduler_bind_type, _) and
erlang:system_flag(cpu_topology, _) have been deprecated and scheduled
for removal in erts-5.10/OTP-R16. For more information see the
documentation of erlang:system_flag/2.
|
|
The common run-queue implementation is removed since it is unused,
untested, undocumented, unsupported, and only complicates the code.
A spinlock used by the run-queue management sometimes got heavily
contended. This code has now been rewritten, and the spinlock
has been removed.
|
|
Calls to erlang:system_flag(schedulers_online, N) and/or
erlang:system_flag(multi_scheduling, block|unblock) could cause
internal data used by this functionality to get into an inconsistent
state. When this happened various problems occurred. This bug was
quite hard to trigger, so hopefully no-one has been effected by it.

The reload mechanism is an odd feature that does not harmonize
with how module upgrade is otherwise done. We do not want its presence
to hinder future development of code loading and upgrade.

* bjorn/erts/remove-useless-variable:
erl_process.c: Remove the redundant variable 'processes_busy'
Update primary bootstrap
otp_internal: Deprecate ssl:pid/1
|
|
There is a static variable called 'processes_busy' in erl_process.c,
which will be incremented but never used.
To confuse things, there is also a global variable with the same
name, but it it is only defined and used if BM_COUNTERS is defined.
In erl_process.c, the global version of 'processes_busy' will be
seen and incremented if BM_COUNTERS is defined.
Remove the static version of 'processes_busy' in erl_process.c,
but keep the global version if BM_COUNTERS is defined.

Add init_iff_file() for verifying the IFF header. Also let it handle
compressed BEAM files so that it will be done in one place. That means
that code:get_chunk/2 and code:module_md5/1 will now support compressed
BEAM files.
|
|
|
|
The undocumented code:get_chunk/2 BIF is supposed to be a fast way
to extract a chunk from a BEAM file when loading native code. In
practice, it might not have been faster because it happened to
calculate an MD5 checksum for the chunk it extracted because it
shared the scan_iff_file() function with the erlang:load_module/2
BIF.
Split scan_iff_file() into scan_iff_file() and verify_chunks(),
so that the unnecessary MD5 calculation can be avoided.
|
|
code:make_stub_module/3 leaked memory if given either a corrupt
BEAM file, or a compressed BEAM file and an error occurred, or
a binary not aligned on byte boundaries.
|
|
Inlining was not done in a portable way. clang follows the C99
semantics for inlining ('inline' essentially implies 'static' in
C99, but not in GCC), so bp_sched2ix() was not visible outside
beam_bp.c. Since the function need to be used from more than one
source file, put the function definition in the beam_bp.h header
file. Also, give it an 'erts_' prefix since it is globally visible.

gcc don't care about the type, but clang does and will issue
a warning.

As of ERTS version 5.9 (OTP-R15B) the runtime system will by default
not bind schedulers to logical processors.
If the Erlang runtime system is the only operating system process that
binds threads to logical processors, this improves the performance of
the runtime system. However, if other operating system processes (as
for example another Erlang runtime system) also bind threads to logical
processors, there might be a performance penalty instead. In some cases
this performance penalty might be severe. Due to this, we change the
default so that the user must make an active decision in order to bind
schedulers.

The spinlocks used implementing pix-locks have been replaced with
mutexes since they perform better during heavy contention.
