E.g OpenBSD's (5.0) patched named does not allow itself to be
started without privilige separation, which is only allowed
for the superuser so test suites can not use that named.
Fix the shell script that starts named to detect early exit
from named and inform the Erlang code test suite what happened.

Common file target.mk now passes the TARGET value through config.sub
for canonification.
Toplevel Makefile now calls target.mk so it handles TARGET like
all sub-makefiles.
Build script otp_build no longer creates a target specific directory
that a long time ago was used for target specific configure cache file.

When a node is shutting down, application_controller will do
exit(Pid,shutdown) on all application masters, and wait for
{'EXIT',Pid,_}. If, for some reason, the application master does not
terminate then application_controller will hang forever waiting for
this 'EXIT' message.
To overcome this problem, a configurable timer is added to kernel -
the enviroment variable 'shutdown_timeout'. If this variable is set to
a positive integer T, application_controller will do exit(Pid,kill)
after T milli seconds if no 'EXIT' message is received.

ets:next needs an explicit safe_fixtable call to be safe, we
rather use ets:foldl and throw to get out of it when we find the
correct entry.

Added session status "new" to mark sessions that are
in the session database to reserve the session id
but not resumable yet and that we want to separate from
sessions that has been invalidated for further reuse.
|
|
The time_stamp filed is now initated in the connection process
init function, so that invalidations of sessions due to handshake failiures,
will not cause sessions in the session table to have
an uninitiated time_stamp field.

If parallel make is used, several instance of 'erlc' is likely to
be invoked at once. Therefore, the default binding of schedulers
to CPU cores will do no good. (With this change, the build of
Erlang/OTP with six threads finished in about 7 minutes; without in
about 11 minutes.)

Break apart code loading into the three functions:
erts_alloc_loader_state()
erts_prepare_loading()
erts_finish_loading()
The erts_alloc_loader_state() and erts_prepare_loading() can be
executed with all schedulers running. Only erts_finish_loading()
needs to be run in a single-scheduling system.
|
|
|
|
There is no reason to have erts_load_module() return integer values,
only to have the caller convert the values to atoms. Return the
appropriate atom directly from the place where the error is generated
instead. Return NIL if the module was successfully loaded.

Calls to global:whereis_name/1 have been substituted for calls to
global:safe_whereis_name/1 since the latter is not safe at all.
The reason for not doing this earlier is that setting a global lock
masked out a bug concerning the restart of supervised children. The
bug has now been fixed by a modification of global:whereis_name/1.
(Thanks to Ulf Wiger for code contribution.)

The -l option used to print information about modules being loaded,
but now it prints very little information.

Remove the special-case handling of the bs_put_string_II
instruction; simply use the string patch mechanism that is already
used for the i_bs_match_string_* instructions.

Fixed a minor race conditions in gen_fsm:start*: if one of these
functions returned {error,Reason} or ignore, the name could still be
registered (either locally or in global.
This is the same modification as was done for gen_server in OTP-7669.

The runtime system crashed if more than one thread tried to exit
the runtime system at the same time.
|
|
Windows native critical sections are now used internally in the
runtime system as mutex implementation. This since they perform
better under extreme contention than our own implementation.
|
|
Queues used for communication between async threads and scheduler threads
have been replaced with lock-free queues.
Drivers using the driver_async functionality are not automatically locked
to the system anymore, and can be unloaded as any dynamically linked in
driver.
Scheduling of ready async jobs is now also interleaved in between other
jobs. Previously all ready async jobs was performed at once.

The implementation of an ERTS internal, generic, many to one, lock-free
queue for communication between threads. The many to one scenario is
very common in ERTS, so it can be used in a lot of places in the future.
Changing to this queue from a lock based queue, however, often requires
some redesigning. This since we have often used the lock of the queue
to protect other information too.
|
|
The ERTS internal system block functionality has been replaced by
new functionality for blocking the system. The old system block
functionality had contention issues and complexity issues. The
new functionality piggy-backs on thread progress tracking functionality
needed by newly introduced lock-free synchronization in the runtime
system. When the functionality for blocking the system isn't used
there is more or less no overhead at all. This since the functionality
for tracking thread progress is there and needed anyway.
|

A number of memory allocation optimizations have been implemented. Most
optimizations reduce contention caused by synchronization between
threads during allocation and deallocation of memory. Most notably:
* Synchronization of memory management in scheduler specific allocator
instances has been rewritten to use lock-free synchronization.
* Synchronization of memory management in scheduler specific
pre-allocators has been rewritten to use lock-free synchronization.
* The 'mseg_alloc' memory segment allocator now use scheduler specific
instances instead of one instance. Apart from reducing contention
this also ensures that memory allocators always create memory
segments on the local NUMA node on a NUMA system.
