If a child of a simple_one_for_one returns ignore from its start
function no longer store the child for any restart type. It is not
possible to restart or delete the child because the supervisor is a
simple_one_for_one.
Previously a simple_one_for_one would crash, potentially without
shutting down all of its children, when it tried to shutdown a child
with undefined pid.
Previous only one undefined pid child was stored in a simple_one_for_one
supervisor no matter how many times the child start function returned
ignore.

Correct filename:split(<<"">>)
|
|
* dgud/stdlib/rand/OTP-12586:
stdlib: Document and add normal distributed random value function
stdlib: Add new random functionality/module
|

Ensure db_has_variable is tested for large Maps as well.
|
|
Strengthen tests of large Maps in ETS.
|
|
The additional tests in match_object focus on ordered sets.
|
|
|
|
filename:split("") returns [], while filename:split(<<"">>) returns
[<<"/">>].
Since the support in the filename module for binary arguments is
much more recent than support for strings, change
filename:split(<<"">>) so that it returns [].

It is needed in various tests. It uses the Ziggurat algorithm, which
is the fastest that I know.

As long as the Erlang Compiler and qlc do not agree on the location of
LC warnings, qlc's own warnings about patterns and filters that always
fail have been silenced.

|

Introduce erl_anno, an abstraction of the second element of tokens and
tuples in the abstract format. The convention that negative line
numbers can be used for silencing compiler warnings will no longer
work in OTP 19; instead the annotation 'generated' is to be used.

The old random module contains an old algorithm which have flaws
and the api requires the user to invoke seed and or checking if seed have
been invoked, if a non constant seed is to be used.
The api contains the following features:
- The user can invoke rand:unform/[0|1] directly and get a non constant seeding.
- The api is split in functional and non functional functions,
i.e. usage of _s functions will not affect the process dictionary.
- The api contains several algorithms with different characteristics and
can be extended with new algorithms in the future.
- Contains state of the art random number generators.
- Default algorithm is taylor made for erlang to be fast on 64bits machines.

fbaa0bec replaced the use of now/0 with erlang:monotonic_time/1 but at
the same time introduced a bug in inPeriod/3 so that it would always
return 'true' (the subtraction Time - Now would always result in
a non-positive number that would always be less than Period).
The symptoms of the bug is that when a child has been restarted the
maximum number of times allowed, the supervisor will terminate,
regardless of how much time that elapses between the restarts.
There was no test case that detected this problem. Add the missing
test case to ensure that this bug stays killed.

According to EEP-43 for maps, a 'badmap' exception should be
generated when an attempt is made to update non-map term such as:
<<>>#{a=>42}
That was not implemented in the OTP 17.
José Valim suggested that we should take the opportunity to
improve the errors coming from map operations:
http://erlang.org/pipermail/erlang-questions/2015-February/083588.html
This commit implement better errors from map operations similar
to his suggestion.
When a map update operation (Map#{...}) or a BIF that expects a map
is given a non-map term, the exception will be:
{badmap,Term}
This kind of exception is similar to the {badfun,Term} exception
from operations that expect a fun.
When a map operation requires a key that is not present in a map,
the following exception will be raised:
{badkey,Key}
José Valim suggested that the exception should be
{badkey,Key,Map}. We decided not to do that because the map
could potentially be huge and cause problems if the error
propagated through links to other processes.
For BIFs, it could be argued that the exceptions could be simply
'badmap' and 'badkey', because the bad map and bad key can be found in
the argument list for the BIF in the stack backtrace. However, for the
map update operation (Map#{...}), the bad map or bad key will not be
included in the stack backtrace, so that information must be included
in the exception reason itself. For consistency, the BIFs should raise
the same exceptions as update operation.
If more than one key is missing, it is undefined which of
keys that will be reported in the {badkey,Key} exception.

Rewrite the code to measure and print elapsed time instead of just
printing timestamps for the start and stop of each operation.
|
|
Use erlang:unique_integer/1 instead.
|
|
Use erlang:monotonic_time/1 instead of now/0.

Use erlang:timestamp/0 instead now/0 when seeding the random
number generator.

In big_test/1, there is 9 seconds sleep before spawning any timers.
Why? Before the sleep nrev processes are started, but they are likely
to finish running before the 9 seconds have elapsed.
Since I see no reason at all for the sleep, I will remove it.

The single test case in timer_SUITE is annoyingly slow. On average,
its running time is about 4 minutes (estimated by a
back-of-the-envelope calculation).
Scale down the delay times in the main loop and the length of timers
started. The running average time should now be around 80 seconds.

The running time for gen_server_SUITE:hibernate/1 is about 12 seconds
because of 1000 ms sleeps in the test case. Introduce a helper
function to avoid sleeping more than necessary.
While we are it, also remove all ?line macros in the test case.

The running time for gen_event_SUITE:hibernate/1 is about 20 seconds

The running time for gen_fsm_SUITE:hibernate/1 is almost 30 seconds
