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.

* bjorn/stdlib/rand-export_seed/OTP-13162:
Correct rand:export_seed/0 when there is no prior seed
|
|
According to the documentation, rand:export_seed/0 should return
'undefined' if the seed has not been intialized. However, it will
create and return a seed. That means that the following code
will not work as expected:
case rand:export_seed() of
undefined -> rand:seen({1,2,3});
_ -> ok
end,
rand:uniform(Range)
|
|
Add parentheses around annotated type union elements in map pair
types. The bug was introduced in Erlang/OTP 18.0.
|
|
Print constraints as 'V :: T' rather than 'is_subtype(V, T)'.

erl_lint:format_error/1 would crash with a function error if
conflicting types were given. That was most easily noticed in the
shell:
Eshell V7.0.3 (abort with ^G)
1> <<0/integer-binary>>.
*** ERROR: Shell process terminated! ***

The test suite depended on the compiler to call
erl_lint:format_error/1 to ensure that format_error/1 was
covered. Unfortunately, though, if format_error/1 crashed
the compiler would catch the exception so that the test suite
would not notice it.
Add a smoke test of format_error/1 that will crash if there is
any problem with erl_lint:format_error/1.

The shell command 'rp' prints strings as lists of integers
when pretty printing of lists is 'false'.

beam_lib:all_chunks/1 and beam_lib:build_module/1 can be useful
for special-purpose stripping, for example to remove the "Line"
chunk.

Prior to this patch, the following code would not eval:
X = key,
(fun(#{X := value}) -> true end)(#{X => value})
That's because the key evaluation was using the new
list of bindings introduced on every anonymous fun.
Since keys only match on values defined prior to the
pattern and do not introduce any new binding, we must
use the full and original list of binding.

Refactor basic_stats/1 into three separate test cases that can be
run in parallel.
|
|
Refactor roundtrip/1 into 4 test cases that can be run in parallel.
Assuming that there are 4 cores available, the group of 4 test
cases will run at roughly one fourth of the time for the original
test case.

On my computer, this will shave off more than one second of the
runnning time and about 4 seconds when cover is being run.

The test that was supposed to call lists:flatten/2 called
lists:flatten/1!
|
|
Remove handling of Clearcase; remove ?line macros.
|
|
Use getline_pred action that fails fast if the shell is not
the oldshell, to avoid having to wait for the timeout.
|
|
Introduce a new {getline_pred, Fun, Msg} action that is useful
in itself, but can also be used to share more code for
{getline, Match} and {getline_re, Match}.
Also get rid of the ?line macros in rtnode() so that we can
somewhat reduce the ridculous indentation level.
|
|
The calls to test_server:sleep/1 are unnecessary as the swapping
of handlers happens in a single process. Even though the
{swap_info,...} message is sent asynchronously, the
gen_event:which_handlers/1 call will not have a chance to
execute until the handlers have been swapped.
|
|
First refactor the entire test case using helper functions
to facilitate further maintenance. Then test that proc_lib
can handle that the process dictionary has been erased
(that will cover more code in proc_lib).
We can also shave off 2 seconds of the execution time by
testing the 'shutdown' exit reasons at beginning of the
test case instead of doing it at the end.
|
|
Use error/1 instead of forcing a badmatch.
|
|
|
|
|
|
Move the test for a bad +pc option to its own test case for
cleanliness. Use the os:cmd/1 function to avoid the annyoying
30 seconds time-out in test_server:start_node/3.
