Subject: [99s-extend] tring to understand ranch_conns_sup
Message-ID: <op.xievlal52w9y7f@zgc-201309221420>

Ranch uses a tcp acceptor pool to accept connections concurrently. But the  
acceptor process
needs to wait for the *only one* ranch_conns_sup spawning the protocol  
process.

Is ranch_conns_sup maybe a bottleneck?

Thanks.

Have you observed ranch_conns_sup be a bottleneck? In practice it 
shouldn't be.

Subject: [99s-extend] [cowboy REST] returning {true, URL} to PUT
Message-ID: <CAH2nEUgJj1f8_RnXqeKqB1tFaDh=qzztOo9XF94S9auQ93dskg@mail.gmail.com>

Hi,

According to the documentation I should be able to return a new
location when handling a PUT request when using cowboy_rest protocol:

    The AcceptResource value is the name of the callback that will be
called if the
    content-type matches. It is defined as follow.

    Value type: true | {true, URL} | false

That works for "true" and "false" but not for "{true, URL}", in that
case the Ranch listener crashes badly[1].

Looking into cowboy_rest.erl I see that the {true, URL} form is
restricted to POST requests:
https://github.com/extend/cowboy/blob/master/src/cowboy_rest.erl#L784

Is that intentional or should I submit a patch to add at least PUT and
PATCH to that condition (or remove all of them if that is not guarding
against something horrible)?

Regards

It's not enabled for PATCH or PUT because it makes little sense for 
them. PATCH and PUT are typically used directly on the URI of the 
resource, even when creating it. While you can return a "better URI" for 
the created resource for them, this should be seen as a special case 
rather than the norm. You can still do it by setting the location header 
manually and Cowboy will react accordingly.

Ok, thanks. That should probably be mentioned in the documentation of
content_types_accepted, as it says {true, URI} is a valid output for
the provided function.

Just out of curiosity from a non-so-expert in REST. The API spec
(which I am not the author of) says the PUT call should create a
resource with a unique id and return the URI of the created resource
in the Location header. That is something like PUT /some/resource
should return /some/resource/1234 in the Location. some/resource is
fixed but 1234 would be generated for each instance of /some/resource.
Is that considered nonsensical?

That's what POST should do.

Compare:

PUT /some/resource/1234 -> no redirect needed
POST /some/resource -> creates /some/resource/1234, redirects

If /some/resource is a collection then PUT on that collection is 
supposed to replace it entirely.

Again it's possible for PUT to create a resource elsewhere, but 
typically the redirect would be from something like 
http://api.yourservice.com/resource/1234 to 
http://cloudthingy.server137.yourservice.com/whatever/resource/1234 and 
not to do what POST is intended for.

Great, thanks for the explanation. I'll try to discuss that with the

Message-ID: <CA+dV7cS+1dfOHFZrMyognVSbVEdX45Rf264ndo0N8nCb1BmnmA@mail.gmail.com>

Hello, y'all.

I'm using HTTP Basic Auth in my API. While calling
cowboy_req:parse_header(<<"authorization>>", ... with an _invalid_
Authorization header such as "Authorization: Basic Test1" I get an error
500 back and an error log message on the server.

1. Is this the expected behavior? [if I understand correctly, my request is
going through authorization(UserPass, Type = <<"basic">>) and this has no
check for the string being correctly encoded]

2. what would be the best way to guard against this "error"?

Thanks.

Parsing of any header may crash. Some may also return an error tuple, 
though that behavior slowly changes and it will always crash in 2.0. So 
just wrap the call around a try/catch if you need to handle the error.

Note that at this exact moment I'm working on returning 400 instead of 
500 automatically when parsing headers end up crashing (and possibly 
other situations later on).

Great, thanks.

I saw some changes "from 422 to 400" in recent versions (PUT and POST).
Thanks for the heads up. As long as they're document, no harm shall come of
these changes.

In any case, if I see it happen very often live I'll "protect" it agains
the _bad_ header :-).

Cheers.

Hi, everybody.

After Erlang updated to 17.1,
when I run q(). command on erlang console, cowboy couldn't quitted but print series of messages..

(after ok signal printed)

?...
=ERROR REPORT==== 26-Jul-2014::15:23:33 ===
Error in process <0.334.0> on node ?...my node name...' with exit value: {{case_clause,{error,closed}},[{ranch_acceptor,loop,3,[{file,"src/ranch_acceptor.erl"},{line,28}]}]}
?.

Before erlang updated (in 17.0), application could be normally quitted exactly same codes and environments.

This is only appeared when I only use ssl(https).
But when use only http with same dispatch rules, cowboy normally quitted.

What?s wrong? or Normal ?

my environment : 
OS : Mac OS X Mavricks
Erlang/OTP : 17.1 from Homebrew
release tool : relx
Cowboy and others : latest
