Sometimes os:timestamp/0 is more appropriate than erlang:now/0. The
documentation for the former has a link to the latter; this patch adds
a link in the other direction to make os:timestamp/0 more visible.

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.

This reverts commit d4667d383964c1550e0a91d64b674e84f6d07e3b.
This commit was included by mistake, the correct patch will
be merged from maint.

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.

Update preloaded erlang.beam
Removed stray error in dialyzer test suite - different error message
with the new specs.
|
|
This involves exception BIF's, guar BIF's and some other complicated BIF's
Also some minor corrections to documentation and specs in erlang.erl
Added comment for each spec in erlang.erl shadowed by erl_bif_types.
Dialyzer test should now run well except for one or two cases.

Reintroduced setelement in erlang.erl and erlang.xml
Preloaded erlang.beam updated.

* sverk/packet_size-http/OTP-9389:
erts: Remove truncation of http packet parsing and return error instead
honor packet_size for http packet parsing to fix OTP-9389
|
|
This is a slight modification of previous commit by Steve Vinoski
For backward compatibility of old users of decode_packet, I think it's enough
to return error instead of keeping the old line truncation behaviour.

* rickard/deprecate-runtime-binding/OTP-9749:
Deprecate erlang:system_flag/2 arguments scheduler_bind_type and cpu_topology
|
|
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.

|
* rickard/default-unbound/OTP-9726:
Use unbound schedulers as default
|
|
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.

Funs are identified by a triple, <Module,Uniq,Index>, where Module is
the module name, Uniq is a 27 bit hash value of some intermediate
representation of the code for the fun, and index is a small integer.
When a fun is loaded, the triple for the fun will be compared to
previously loaded funs. If all elements in the triple in the newly
loaded fun are the same, the newly loaded fun will replace the previous
fun. The idea is that if Uniq are the same, the code for the fun is also
the same.
The problem is that Uniq is only based on the intermediate representation
of the fun itself. If the fun calls local functions in the same module,
Uniq may remain the same even if the behavior of the fun has been changed.
See
http://erlang.org/pipermail/erlang-bugs/2007-June/000368.htlm
for an example.
As a long-term plan to fix this problem, the NewIndex and NewUniq
fields was added to each fun in the R8 release (where NewUniq is the
MD5 of the BEAM code for the module). Unfortunately, it turns
out that the compiler does not assign unique value to NewIndex (if it
isn't tested, it doesn't work), so we cannot use the
<Module,NewUniq,NewIndex> triple as identification.
It would be possible to use <Module,NewUniq,Index>, but that seems
ugly. Therefore, fix the problem by making Uniq more unique by
taking 27 bits from the MD5 for the BEAM code. That only requires
a change to the compiler.
Also update a test case for cover, which now fails because of the
stronger Uniq calculation. (The comment in test case about why the
Pid2 process survived is not correct.)

For the subsection about process_flag(save_calls, N) there's an
unrelated paragraph about process priorities which was copied
from the preceeding subsection regarding process_flag(priority, Level).
