Hello.
I have a well localized problem with Ranch that raises several basic
questions about OTP, which i need to understand in order to solve the
problem.
i have got the following applications running on a single isolated node:
1> application:which_applications().
[{online37,"My Application","0.1.0"},
{cowboy,"Small, fast, modular HTTP server.","1.0.0"},
{ssl,"Erlang/OTP SSL application","5.3.6"},
{public_key,"Public key infrastructure","0.22.1"},
{cowlib,"Support library for manipulating Web protocols.",
"1.0.0"},
{mnesia,"MNESIA CXC 138 12","4.12.3"},
{crypto,"CRYPTO","3.4.1"},
{asn1,"The Erlang ASN1 compiler version 3.0.2","3.0.2"},
{ranch,"Socket acceptor pool for TCP protocols.","1.0.0"},
{stdlib,"ERTS CXC 138 10","2.2"},
{kernel,"ERTS CXC 138 10","3.0.3"}]
Q1: does this list represent the starting order of these applications
listed?
Q2: may i deduce from this list that 'ssl' will be stopped before
'ranch'? (should be called init:stop/0)
the main problem is that during init:stop/0
'ranch' *DELIBERATELY* crashes with the reason: "socket closed"
(in src/ranch_acceptor.erl:28)
(which in my opinion most probably is caused by preliminary shut down of
'ssl')
Q3: am i right in respect of 'ranch' that 'ssl' shall not be stopped
before 'ranch'?
my .app.src file (which corresponds to the applications listing above) is:
{application, online37, [
{description, "My Application"},
{vsn, "0.1.0"},
{modules, []},
{registered, []},
{applications, [
kernel,
stdlib,
ssl,
mnesia,
cowboy
]},
{mod, {online37_app, []}},
{env, []}
]}.
Q4: how could i affect the starting order of the applications? (provided
i am using erlang.mk + relx)
