First and foremost: yes, you can still use Cowboy as a rebar dependency.
This commit only removes the use of rebar when *developing* Cowboy, not
when *using* Cowboy.
Over the past two years I went from very happy with rebar to unsatisfied
and most recently found it counter productive in many ways, from having
insane default configuration to various unefficient operations. The earlier
reversal from 'rebar ct' to 'ct_run' made my workflow much more natural,
as I always needed to look at 'logs/raw.log' to find out what was wrong,
anyway. Why not let 'ct_run' output it directly instead? Removing rebar
made my life easier.
If you wonder why I don't patch rebar, there's two reasons. First is that
the direction taken by rebar isn't compatible with my views, and this
would be a huge fight to steer it in another direction. I got other,
more important fights to make. Second is that I'd rather patch OTP so
that everyone benefits from it, not just users of rebar.
Anyway this isn't my personal blog so I will stop babbling here. There's
a few important things to note relative to this commit:
* You don't need rebar to work on Cowboy anymore
* The eunit tests are now ran through common_test
Ping me if it doesn't work out for you.

Small tweak to the autobahn test file, we look for the python2
executable now. It'll make my life easier.

|
Middlewares allow customizing the request processing.
All existing Cowboy project are incompatible with this commit.
You need to change `{dispatch, Dispatch}` in the protocol options
to `{env, [{dispatch, Dispatch}]}` to fix your code.

This commit prevents erlang messages from keeping a websocket connection
alive. Previously, the timer was canceled upon any activity. Now, the
timeout is only canceled when actual data is sent from the client. The
handler_loop_timeout/1 function is called from websocket_data/4 instead
of handler_before_loop/4. It is also called after every successful reply
in handler_call/4.

Add the function cowboy_clock:rfc1123/1 that formats the given
date to the RFC1123 format.
|

We can now reply empty close, ping and pong frames, or close
frames with a payload.
This means that we can send a frame and then close the connection
in a single operation.
If a close packet is sent, the connection is closed immediately,
even if there was frames that remained to be sent. Cowboy will
silently drop any extra frames in the list given as a reply.

Instead of returning {text, Data}, you can now return
[{text, Data}, {text, Data2}, ...].
|
|
All tests still pass! (Excluding UTF-8 of course.)
|
|
As suggested by @prof3ta.
|
|
We do not always provide the body however. It is not available
when using chunked replies, or when using set_resp_body_fun.
|
|
It is only enforced when Cowboy needs to wait for more data.
Also fix a few types and a few status codes.
|
|
* #state{} changes are avoided where possible
* #state{} is now smaller and use less memory
* the Req object is created only after the whole request is parsed
* parsing makes use of a single binary match context
* external calls are avoided in the critical path
* URL fragment is now extracted properly (retrieval API next commit)
* argument orders to local functions modified to avoid extra operations
* dispatching waits as long as possible before tokenizing host/path
* handler opts are no longer shown in the error messages except in init
The code may not look as beautiful as it was before. But it really
is, for parsing code. The parsing section of the file may be skipped
if your eyes start to burn.

The internal host_tokens value now has host tokens in reverse order
compared to before. This allows us to remove one lists:reverse call.
|
|
Here we do not remove decode_packet yet, we just lowercase the
header name and transform it into a binary if needed, to fix
the consistency issue.
|
|
Header names are now binaries. Since header names are case insensitive
they are all converted to lowercase. For example: <<"content-length">>.
The max_line_length option was removed. Three new options have been
added instead:
* max_request_line_length (defaults to 4096)
* max_header_name_length (defaults to 64)
* max_header_value_length (defaults to 4096)
|
|
First step in making all methods and header names binaries to
get rid of many inconsistencies caused by decode_packet/3.
Methods are all binary now. Note that since they are case
sensitive, the usual methods become <<"GET">>, <<"POST">> and so on.
|
|
The signature of parse_header, body_qs, multipart_data and
the set_resp_* functions has changed.
See the cowboy_req module edoc for more details.
|
|
The latter is much more useful than the former, which ends up
being removed.

This effectively drops the R14B compatibility.
The cowboy_req:req() type will be introduced in a future commit.
It refers to the #http_req{} record.
|
|
This is the first of many API incompatible changes.
You have been warned.
|
|
Also update the CHANGELOG and copyright years.
|
|
|
|
Fix alphabetical order since @klaar seems to have issues with it. ;)

This new protocol option is a fun.
It expects 3 args: the Status code used in the reply (this is the
cowboy_http:status() type, it can be an integer or a binary), the
headers that will be sent in the reply, and the Req. It should
only return a possibly modified Req. This can be used for many
things like error logging or custom error pages.
If a reply is sent inside the hook, then Cowboy will discard the
reply initially sent. Extra caution must be used in the handlers
making use of inline chunked replies as they will throw an error.
This fun cannot be used as a filter, you can either observe the
reply sent or discard it to send a different one instead.
The hook will not be called for replies sent from inside the hook.

Use a proper HTTP client to run all tests. This client is currently
undocumented and should not be used.
Includes a few fixes:
* Fix a bug in the max_keepalive test
* Fix a bug with max_keepalive handling
* Fix a bug in stream_body/1 where data was lost under some conditions
The tests now run quite faster than before.
All the tests now run twice: once for TCP, once for SSL.

Introduces 3 low level functions and updates the existing higher
levels functions. The new primitives are has_body/1, body_length/1
and stream_body/1. In addition to that, a helper function
init_stream/4 has been added.
Streaming a body implies to decode the Transfer-Encoding and
Content-Encoding used for the body. By default, Cowboy will try
to figure out what was used and decode them properly. You can
override this if you want to disable this behavior or simply
support more encodings by calling the init_stream/4 function
before you start streaming the body.
|
|
This new protocol option is a fun.
It expects a single arg, the Req, and should only return a possibly
modified Req. This can be used for many things like URL rewriting,
access logging or listener-wide authentication.
If a reply is sent inside the hook, then Cowboy will consider the
request handled and will move on to the next one.

Fixes compatibility issue #140 reported by @majek.
