* 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.
|
|
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! ***
Noticed-by: Aleksei Magusev

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.

Introduced when changing state from tuple to record.

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.

* howleysv/stdlib/compiled-unicode/OTP-12977:
stdlib: Fix bug with unicode detection in re
|
|
|
|
Fix bug with unrecognised 'unicode' option in re:split/2,3 &
re:replace/3,4 when using pre-compiled regex.
|
|
We'll need a way to limit the size of the crash report produced
by proc_lib:format(). Add format/3, where the third argument is
a depth argument.
|
|
Add the possibility to truncate big messages to avoid running out
of memory.

Report handlers are not automatically removed. That means
that the report handler will remain installed until the entire
running of the stdlib test suite finishes. That could potentially
cause problems.
|
|
The unzip_to_binary/1 and zip_to_binary/1 test cases need the
test_server's priv_dir to be empty. On Windows, file system
pecularities can prevent us from emptying priv_dir.
Since the point of this test case is not to test file operations
on Windows, simplify things by working in a newly created sub
directory of priv_dir.

As pointed out by roowe, qlc does not handle errors in early compiler
(scanner, parser) well in OTP 18.0.
