I did not find any legitimate use of "can not", however skipped
changing e.g RFCs archived in the source tree.

Communication between Erlang processes has conceptually always been
performed through asynchronous signaling. The runtime system
implementation has however previously preformed most operation
synchronously. In a system with only one true thread of execution, this
is not problematic (often the opposite). In a system with multiple threads
of execution (as current runtime system implementation with SMP support)
it becomes problematic. This since it often involves locking of structures
when updating them which in turn cause resource contention. Utilizing
true asynchronous communication often avoids these resource contention
issues.
The case that triggered this change was contention on the link lock due
to frequent updates of the monitor trees during communication with a
frequently used server. The signal order delivery guarantees of the
language makes it hard to change the implementation of only some signals
to use true asynchronous signaling. Therefore the implementations
of (almost) all signals have been changed.
Currently the following signals have been implemented as true
asynchronous signals:
- Message signals
- Exit signals
- Monitor signals
- Demonitor signals
- Monitor triggered signals (DOWN, CHANGE, etc)
- Link signals
- Unlink signals
- Group leader signals
All of the above already defined as asynchronous signals in the
language. The implementation of messages signals was quite
asynchronous to begin with, but had quite strict delivery constraints
due to the ordering guarantees of signals between a pair of processes.
The previously used message queue partitioned into two halves has been
replaced by a more general signal queue partitioned into three parts
that service all kinds of signals. More details regarding the signal
queue can be found in comments in the erl_proc_sig_queue.h file.
The monitor and link implementations have also been completely replaced
in order to fit the new asynchronous signaling implementation as good
as possible. More details regarding the new monitor and link
implementations can be found in the erl_monitor_link.h file.

There are still some query residues used as a keyword. Remove them.
query was no longer a keyword since the commit 0dc3a29744bed0b7f483ad72e19773dc0982ea50 2012-11-19.

typer.c is re-introduced in the OTP-repository, so the typer
executable should still be listed in default exclude filters in
reltool.

For applications that are not included in a 'rel' spec in the reltool
config, dependencies in the .app file are not followed. This is now
corrected.
|
|
For applications that are included in a 'rel' spec in the reltool
config, some dependency chains are not followed. E.g.
* Application x has y as included application, and y in turn has z as
included application. Then z is not included.
* Application x has y in its 'applications' tag in the .app file, and
y in turn has z as included application. Then z is not included.
This is now corrected - all app-file dependencies are recusively
followed for all applications that are included in a 'rel' spec in the
reltool config.

For applications that are explicitly included in the reltool config,
but that are not included in a 'rel' spec, dependencies in the .app
file are not followed (only xref dependencies are taken care of).
