A bug fix: limited maps end with "...", not "...=>...".
A modification: wW separate pairs with " => ", not "=>".
When the output is limited on number of characters, the term is
balanced by wW the same way as is done with pP (see commit bc38638).
|
|
The name of the io_lib_pretty:print/2 option 'max_chars' is changed to
'line_max_chars' (used by module shell only).
The new option for limiting the number of returned characters of
io_lib_pretty:print() is called 'chars_limit'.

Implementation of true asynchronous signaling between processes
|
|
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The previously used message queue partitioned into two halves has been
replaced by a more general signal queue partitioned into three parts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.

stdlib: Add function lists:search/2

|
Allow multiple modifier characters in io:format control sequences
OTP-14971
|
|
This makes it possible to print unicode atoms at the same time as
suppressing detection of printable lists.
|
|
This is essentially PR 102, https://github.com/erlang/otp/pull/102.
The OTP Technical Board decided to change the name of the function to
search/2.
