Add short sleep when killing slave nodes
[ct test] Do reload_config instead of get_config
|
|
slave_SUITE:t_start_link somtimes fails when checking that a slave is
dead. This commit add a short sleep before the check to allow the node
to terminate.

It is possible that '...' is added later (OTP 20.0), but for now we
are not sure of all details.

* josevalim/supervisor-get-callback-module/PR-1000/OTP-13619:
Return callback module in supervisor format_status
|
|
|
|
The previous implementation of supervisor:get_callback_module/1
used sys:get_status/1 to get the supervisor inner state and
retrieve the callback module. Such implementation forbids any
other supervisor implementation that has an internal state
different than the #state{} record in supervisor.erl.
This patch allows supervisors to return the callback module
as part of the sys:get_status/1 data, no longer coupling the
callback module implementation with the inner #state{} record.
Notice we have kept the clause matching the previous
sys:get_status/1 reply for backwards compatibility purposes.

Seems to be the growing meta tables that is causing increasing
failed memchecks after load factor was lowered.

Change ct:sleep to timer:sleep where scaling is not wanted
Don't generate ssh key files in netconf client test
Ignore data received in break mode in test telnet_server
Wait for process to die before next call
Retry ct_telnet:get_data if no data is received after short wait
Don't throw rest of line when NOP is received in test telnet_server
Change ct:sleep to timer:sleep in telnet_server

In particular, valgrind needs a lot of time for certain tests.
|
|
gen_server_SUITE:start often fails since a call which is expected to
give 'noproc' error instead gives 'stopped' error. This happens when
the call is done before the process is really dead. To overcome this
problem, we now wait for the process exit before doing the call.

Fix deprecated warnings

Add documentation
epp: Add the -error and -warning directives

In current deprecated warnings such as `crypto:rand_bytes/1 is deprecated
and will be removed in in a future release; use crypto:strong_rand_bytes/1`,
the word "in" is duplicated.

If one of several alternatives configurations are required for
an Erlang module to compile, but none are available, it would
be useful to give a nice error message. For example:
-ifdef(CONFIG_A).
%% Some code if A is true.
-else.
-ifdef(CONFIG_B).
%% Some code if B is true.
-else.
-error("Neither CONFIG_A nor CONFIG_B are available").
-endif.
-endif.
If neither CONFIG_A nor CONFIG_B are defined, the error message
will be:
module.erl:10: -error("Neither CONFIG_A nor CONFIG_B are available").
That is basically the same behavior as for the #error directive in
GCC.
For symmetry with the -error directive, add the -warning
directive to generate a compiler warning. For example:
-ifdef(HAVE_COOL_FEATURE).
%% Code if we have Cool Feature.
-else.
%% Inefficient fallback code.
-warning("Using inefficient fallback").
-endif.
If HAVE_COOL_FEATURE is not defined, the warning message will
be:
module.erl:8: Warning: -warning("Using inefficient fallback").
That is basically the same behavior as for the #warning directive
in GCC.

The use case is not cryptographical but we want to compare Erlang
implementation to c implementation so use crypto:strong_rand_bytes anyway.
|
|
Also move check of non-atom states in callback mode
state_functions to where the state function is called.
This gives homogenous diagnostics for state functions,
code_change/4 and system_replace_state StateFun.
Irregularities pointed out by James Fish.

Add a call which works much like string:join/2 but for arbitrary lists. Provide
the function itself, lifted from Haskells Data.List standard library, provide
documentation and provide tests for the function.

* lukas/stdlib/error_logger_SUITE/OTP-13471:
stdlib: Fix logfile testcase for hipelibs testrun
|

abnormal1/1 started failing sporadically when 22785cd1e21
changed using the messages_get/0 and using its own implementation:
get_messages() ->
receive
Msg -> [Msg|get_messages()]
after 1 -> []
end.
In test_server:messages_get/0, there was "after 0" instead of "after
1" as in this version.
We could change back to using "after 0", but it seems that the
test case just happened to work before the change.
Instead, read out the message that is guranteed to be in the message
queue, and *then* check that the message queue is empty.

In 8d7d5627, test_server:sleep/1 was changed to ct:sleep/1.
Change it to timer:sleep/1 to make the timing more exact
(ct:sleep/1 will call another process).
|
|
to make it kill and then wait for all spawned processes to exit.
