inets: Fix handling of 'Content-Type' (httpc)
Change-Id: I8c9f48d8474dba7a83e4ecba6b8146faffb559fc
|

'Content-Type' is sent when it is explicitly set as a header or
there is a non-empty body in the request.
Former implementation dropped the explicit 'Content-Type' when
the request had an empty body.

RFC7230 3.3.2
A sender MUST NOT send a 'Content-Length' header field in any message
that contains a 'Transfer-Encoding' header field.

Strict REST APIs does not accept HTTP requests that have no body
but still include a 'Content-Type' header. RFC7231 does not
forbid this corner case but as it causes interoperatbility
problems in client software we opt to not send the 'Content-Type'
header when the body is not present.

Proxies want absolut URIs, but once a TLS tunnel is set up
it is like talking direct to the server.

httpc manager crashes.When a request results in a retry, the request
id will be "reused" in the previous implementation a race condition
could occur causing the manager to crash. This is now avoided by using
proc_lib:init_ack and gen_server:enter_loop to allow more advanced
initialization of httpc_handlers without blocking the httpc_manger
and eliminating extra processes that can cause race conditions.

Also fixed some of the documentation (types).

This is a must when uploading large bodies that are to large to store
in a string or binary.
Besides a string or binary, a body can now be a function and
an accumulator.
Example:
-module(httpc_post_stream_test).
-compile(export_all).
-define(LEN, 1024 * 1024).
prepare_data() ->
{ok, Fd} = file:open("test_data.dat", [binary, write]),
ok = file:write(Fd, lists:duplicate(?LEN, "1")),
ok = file:close(Fd).
test() ->
inets:start(),
ok = prepare_data(),
{ok, Fd1} = file:open("test_data.dat", [binary, read]),
BodyFun = fun(Fd) ->
case file:read(Fd, 512) of
eof ->
eof;
{ok, Data} ->
{ok, Data, Fd}
end
end,
{ok, {{_,200,_}, _, _}} = httpc:request(post, {"http://localhost:8888",
[{"content-length", integer_to_list(?LEN)}], "text/plain", {BodyFun, Fd1}}, [], []),
ok = file:close(Fd1).

between the httpc manager and request handler was synchronous.
When the manager starts a new request handler, this is no longer
a synchronous operation. Previously, the new request handler made
the connection to the server and issuing of the first request
(the reason for starting it) in the gen_server init function. If
the connection for some reason "took some time", the manager
hanged, leaving all other activities by that manager also
hanging. As a side-effect of these changes, some modules was also
renamed, and a new api module, httpc, has been introduced (the
old module, http, is *not* removed, but is now just wrapper for
httpc).
