* feat(emqx_conf): move conf manager for emqx_machine to emqx_conf
* chore(emqx_conf): change emqx:get_config/2 to emqx_conf:get/2
* fix: common test failed
* fix: badmatch by typo wrong key
* fix(emqx_conf): get the wrong core nodes
* fix(emqx_conf): get core node's tnx_id not latest tnx_id
* fix: add ro_transation when copy conf file
* fix: delete debug info
* fix: change ekka_rlog to mria_rlog
* fix: remove cluster_rpc from emqx_machine.
* fix: don't call ekka:start/0 explicitly
* fix: ekka should be start in emqx_machine
prior to this cahnge emqx node shutdown is done by init:stop
which might have undesired stop order of the applications
in this change, emqx_machine_terminator is added to stop apps
in defined order and then terminate the node in infinite loop
prior to this fix the logger message (syslog) has the name and pid
missing.
with this change, the programe name, and its boot command is logged
to syslog, so the console boot is cleaner
* fix(hocon): fail on hocon command errors
call_hocon bash function respects exit code
* fix(bin/emax): get dist_port config from hocon
after config file refactoring (to hocon format) the grep pattern
no longer works
* fix(bin/emqx): set -o pipefail
* feat(bin/emqx): add a DEBUG option
nodetool has all lib paths set up correctly by reading the
persisted RELEASES file
calling hocon escript directly has two problems:
1. it may not be able to find the beams compiled
2. if we use ERL_LIBS, it may find the version after hot beam upgrade
previously we supports skipping config generation if USE_CUTTLEFISH
not set to true.
it has never been tested (at least not in automated tests)
now it's time to drop it.
