%% ranch_conns_sup is a custom supervisor (special process),
|
|
%% not an OTP supervisor. When "supervisor" is used, the
|
|
%% module is always loaded before calling system_code_change,
|
|
%% for both upgrade and downgrade operations. This is so that
|
|
%% the supervisor's init callback of the upgraded/downgraded
|
|
%% module gets called. But the custom supervisors in Ranch
|
|
%% do not have an init callback and therefore can function
|
|
%% like other special processes: when upgrading, load the
|
|
%% module then call system_code_change; and when downgrading,
|
|
%% call system_code_change and then load the module.
