* sverk/bad_printable_range:
stdlib: Fix io_SUITE:bad_printable_range for windows
|
|
Since Windows 8 we are not allowed (in non elevated mode) to
write to hklm.
|
|
avoid os:cmd as it treats stderr different on windows.

On a computer which is fast, but with timers with low resolution,
the measured time for an empty queue could be zero, which could
cause the test case to fail.
Add a calibration function to scale up the amount the amount of
work so that the measured time will not be lower than 50 ms.

Removing events from the internal queues is not necessary with
the choosen semantics of the event queue vs. hibernate.
In an early implementation it was possible by combining
hibernate with e.g. postpone to get an event in the queue
that you would not see before processing the postponed event,
and therefore should you decide to cancel a timer it was
essential to be able to remove that unseen event from the queue.
With the choosen semantics you will have to postpone or generate
an event for it to be in the event queue, and if you e.g. postpone
a timeout event and then cancel the timer it is your mistake.
You have seen the event and should know better than to try to
cancel the timer.
So, the actions: remove_event, cancel_timer, demonitor and unlink
are now removed.
There have also been some cleanup of the timer handling code.

For a long time, users have asked for one or more macros that would
return the name and arity of the current function.
We could define a single ?FUNCTION macro that would return
a {Name,Arity} tuple. However, to access just the name or
just the arity for the function, element/2 must be used.
That would limit its usefulness, because element/2 is not
allowed in all contexts.
Therefore, it seems that we will need two macros.
?FUNCTION_NAME that expands to the name of the current function
and ?FUNCTION_ARITY that expands to arity of the current
function.
Converting the function name to a string can be done like this:
f() ->
atom_to_list(?FUNCTION_NAME) ++ "/" ++
integer_to_list(?FUNCTION_ARITY).
f/0 will return "f/0". The BEAM compiler will evaluate the
entire expression at compile-time, so there will not be
any run-time penalty for the function calls.
The implementation is non-trivial because the preprocessor is
run before the parser.
One way to implement the macros would be to replace them with some
placeholder and then let the parser or possibly a later pass replace
the placeholder with correct value. That could potentially slow
down the compiler and cause incompatibilities for parse transforms.
Another way is to let the preprocessor do the whole job. That means
that the preprocessor will have to scan the function head to find
out the name and arity. The scanning of the function head can be
delayed until the first occurrence of a ?FUNCTION_NAME or
?FUNCTION_ARITY.
I have chosen the second way because it seems less likely to cause
weird compatibility problems.

Problem: The types of record fields have since R12B been put in a
separate form by epp:parse_file(), leaving the record declaration form
untyped. The separate form, however, does not follow the syntax of
type declarations, and parse transforms inspecting -type() attributes
need to know about the special syntax. Since the compiler stores the
return value of epp:parse_file() as debug information in the abstract
code chunk ("Abst" or 'abstract_code'), tools too need to know about
the special syntax, if they inspect -type() attributes in abstract
code.
Solution: As of this commit no separate form is created by
epp:parse_file(), but the type information kept in the record fields.
This means that all parse transforms and all tools inspecting
-record() declarations need to recognize {typed_record_field, Field,
Type}.
We recommend that all parse transforms and tools be updated as to
recognize typed record fields.
Discussion: As of OTP 19.0, the abstract form of type declarations and
function specifications is documented. An (unsatisfactory) alternative
to the above solution is to document two formats of the abstract form
of typed record fields: one if returned by epp:parse_file(); and one
if returned by, for example, epp:parse_erl_form(). Yet another (bad)
alternative is to not document the format returned by epp:erl_parse(),
but instead document the idempotent function
epp:restore_typed_record_fields/1, and urge authors of parse transform
and tools to always call this function.

Since no test suites includede test_server.hrl, there is no need
to have test_server in the include path or code path.
|
|
As a first step to removing the test_server application as
as its own separate application, change the inclusion of
test_server.hrl to an inclusion of ct.hrl and remove the
inclusion of test_server_line.hrl.

|
The two bad record usage test cases in compile_SUITE do not
belong there, as the errors are detected in erl_lint. Move the
test to the erl_lint_SUITE.

Speed up supervisor:count_children/1 for simple_one_for_one
supervisors. This is achieved by avoiding looping through all the
child process and verifying that each one is alive.
For a supervisor with 100,000 'temporary' children the count-time will
drop from approx 25ms to about 0.005ms.
For a supervisor with 100,000 'permanent' or 'transient' children the
count-time will drop from approx 30ms to about 0.005ms.
This avoids having the supervisor block for an extended period while
the count takes place. Under normal circumstances the accuracy of the
result should also improve since the duration is too short for many
processes to die during the count.

The Dets server pretends the file is open before internal_open()
has been called, which means that unless the internal_open
message is applied first, other processes can find the pid by
calling dets_server:get_pid() and do things before Head has been
initialized properly.
|
|
The new time warp safe option is safe_fixed_monotonic_time which
gives erlang:monotonic_time().
The safe_fixed option was also slightly changed. It now gives
erlang:timestamp() instead of erlang:now(). This has however
not been documented, so it is considered a compatible change.
The above effects both ets, and dets.
This commit also include the bugfix OTP-13239 for
dets:info(Tab, safe_fixed). The timestamp in the result returned
by dets:info(Tab, safe_fixed) was unintentionally broken as a
result of the time API rewrites in OTP 18.0.
