In rare circumstances, there can be a race when the crypto key server
is started by beam_lib:crypto_key_fun/1 shortly after stopping it
using beam_lib:clear_crypto_key_fun/0. The race occurs because
the crypto key server first sends back the reply to the calling
process, then terminates. (The race is probably more likely to happen
on CPUs with hyper threading.)

tar_SUITE: Work around limited pathname length on Windows
|
|
* pan/erl-bif-types/OTP-9496:
Cleanup ETS bif's in hipe:erl_bif_types.erl (for dialyzer)
|
|
Ever since the test suites were converted to the common_test
convention, the tests for long names started to fail on Windows. The
reason is that those test cases depend on the current working
directory, and that the current working directory in common_test test
cases is usually set to a directory with a longer pathname than in
test_server test suites.
Since neither Erlang/OTP nor common_test provides a portable way
to create a temporary directory with a short name, we will have to
abuse priv_dir by going upwards from it. For further information,
see the comment in run_in_short_tempdir/2.

Add a high value to test data to catch type cast truncation errors

Running Dialyzer on the test suites revealed a few type errors.

In the current implementation of supervisors, temporary children
should never be restarted. However, when a temporary child is
restarted as part of a one_for_all or rest_for_one strategy where
the failing process is not the temporary child, the supervisor
still tries to restart it.
Because the supervisor doesn't keep some of the MFA information
of temporary children, this causes the supervisor to hit its
restart limit and crash.
This patch fixes the behaviour by inserting a clause in
terminate_children/2-3 (private function) that will omit temporary
children when building a list of killed processes, to avoid having
the supervisor trying to restart them again.
Only supervisors in need of restarting children used the list, so
the change should be of no impact for the functions that called
terminate_children/2-3 only to kill all children.
The documentation has been modified to make this behaviour
more explicit.

zip:zip_open/1,2 did not accept binary archives.
Also corrected the contracts of t/1 and tt/1.

Replace the count_children_allocator_test with try erlang:memory in
order to make sure there is no attempt at running this test case if
erlang:memory is not supported.

Since initial arguments of temporary children under simple_one_for_one
supervisors are not saved, only a list of pids was stored in such
supervisors. When adding/deleting many children, this would scale
badly. To avoid this the list is now changed to a set.

'siri/stdlib/supervisor-terminate_child-simple_one_for_one/OTP-9201' into dev

Add terminate_child(Sup, Pid) for simple_one_for_one
Allow supervisor:terminate_child(SupRef,Pid) for simple_one_for_one

supervisor:terminate_child/2 was not allowed if the supervisor used
restart strategy simple_one_for_one. This is now changed so that
children of this type of supervisors can be terminated by specifying
the child's Pid.

terminates" and improved test suite
The bug fix supplied by Filipe David Manana <[email protected]>
did not cover all possible ways that a process may be terminated
as for instance with supervisor:terminate_child. Also there
was a bug in the base case of the patch returning a list of a list instead
of only the list.
Added a timeout for the test cases, eliminated unnecessary sleeps,
improved code.

In the following code:
m(<<Sz:8,_:Sz/binary>>) ->
Sz = wrong.
the Sz variable is supposed to be bound in the function header and the
matching "Sz = wrong" should cause a badarg exception. But what
happens is that the Sz variables seems to be unbound and the matching
succeds and the m/1 function returns 'wrong'.
If the Sz variable is used directly (not matched), it will have
the expected value. Thus the following code:
m(<<Sz:8,_:Sz/binary>>) ->
Sz.
will correctly return the value of Sz that was matched out from
the binary.

The default value 'undefined' was added to records field types in such
a way that the result was not always a well-formed type. This bug has
been fixed.
---
erl_pp has since OTP-8150 formatted types so that 'undefined' was
removed from union types assigned to record fields. Since one cannot
distinguish between 'undefined' added by the parser or supplied by the
user, a side effect was that user supplied 'undefined's were also
removed.
Now the pretty printer shows 'undefined' even if added by the parser.
This is a minor issue.

This new feature adds the missing week number function to the calendar module
of the stdlib application. The implementation conforms to the ISO 8601 standard.
The new feature has been implemented tested and documented.

dialyzer spec.
|

Previous commit changed the supervisor to not save
parameter lists for temporary processes supervised by simple-one-for-one
supervisors. But it is unnecessary to save them for any
temporary processes as they should not be restarted. Proably the
biggest gain is in the simple-one-for-one case.
Also changed the test case count_children_memory so it does
not test that which_children will produce garbage that must
be reclaimed later. This is a strange thing to test and it is no
longer true for all invocations of which_children.
