Vinnie Falco e8be3fd7d3 New HTTP interfaces (API Change): 
fix #123
fix #154
fix #265

This completely replaces the HTTP parser used to read and
parse incoming messages. The new version is faster than
the old one, and written in fewer lines. A summary of
changes:

* parse and async_parse renamed to read and async_read

* basic_parser is optimized for linear buffers,
  use flat_streambuf for the best performance with these
  functions:

  - http::read
  - http::read_some
  - http::async_read
  - http::async_read_some

* The overloads of read() and async_read() which take
  just a header have been removed, since they would
  throw away important parse metadata.

* The derived class callbacks for basic_parser have
  been streamlined. All strings passed to callbacks
  are presented in their entirety, instead of being
  provided in pieces.

These changes allow use-cases that were previously
difficult or impossible, such as:

- Efficient relaying

- Late body type commitment

- Expect: 100-continue handling

Vinnie Falco e7319aade1 Add flat_streambuf: 
Objects of this type meet the requirements of DynamicBuffer
and offer an additional invariant: buffer sequences returned
by data() and prepare() are always of length one.

Vinnie Falco 0ec9e8c4af Allow concurrent websocket async ping and writes: 
fix #271

This modifies the websocket stream implementation's composed
operations to allow caller-initiated asynchronous pings and
frame/message writes to take place at the same time.

Vinnie Falco 765cb22b48 Invoke callback on pings and pongs (API Change): 
fix #248

This additionally invokes the pong callback for received pings, allowing
callers to more efficiently detect when a connection is still lively:

* pong_callback renamed to ping_callback
* Callback signature has an extra `bool` to indicate if the received
  control frame is a ping or pong.

Vinnie Falco 911617c43f Add permessage-deflate WebSocket extension: 
This implements the permessage-deflate WebSocket
extension as described in HyBi Working Group
draft-ietf-hybi-permessage-compression-28:
https://tools.ietf.org/html/draft-ietf-hybi-permessage-compression-28

This extension allows messages to be compressed using
the raw "deflate" algorithm described in RFC 1951,
"DEFLATE Compressed Data Format Specification version 1.3":
https://www.ietf.org/rfc/rfc1951.txt

Vinnie Falco 01e1fa2dc9 Implement asio dealloc-before-invoke guarantee: 
fix #215

This change guarantees that temporary memory allocated
through the asio hooks by the Beast implementation is
deallocated before invoking the final handler when performing
composed operations.

The change is accomplished by replacing std::shared_ptr with
a thread-safe custom container handler_ptr to manage composed
operation state. The container tracks other instances which
manage the same object and resets them in a safe way before
invoking the final handler.

handler_ptr is provided as a public interface so that users of
this library can utilize the same idiom to write their own
composed operations.

Vinnie Falco e3848e7281 Refactor HTTP identifier names (API Change): 
fix #171

Several names and  HTTP identifiers are renamed to be
more consistent, self-explanatory, and concise:

* "Fields" is a collection of HTTP header fields (rfc7230 section 3.2)
* "Header" is the Start Line plus Fields. Another way to look at it is,
  the HTTP message minus the body.
* `basic_fields` replaces `basic_headers`
* `fields` replaces `headers`
* `Fields` replaces `Headers` in template parameter lists
* `header` replaces `message_headers`
* `header::fields` replaces `message_headers::fields`

The changes are cosmetic and do not affect run-time behavior.

Vinnie Falco 6afa6afc98 Fix consuming_buffers value_type (API Change): 
This fixes a bug where instantiations of consuming_buffers with
buffer sequence types whose value_type is not const_buffer or
mutable_buffer can cause compilation errors.

The function consumed_buffers is removed.

Vinnie Falco f98ec17121 Make chunk_encode public: 
fix #154, fix #156

This adds public interfaces for transforming buffer
sequences into their chunk-encoded equivalents. The
transformations are O(1) in space and time.
 2017-07-20 08:12:13 -07:00
Vinnie Falco 50bc9a58cd Refactor message and message_headers declarations: 
message_headers is now a set of partial class template
specializations instead of a template class alias. This solves
a problem where template functions taking message_headers as a
parameter could not deduce argument types, since std::conditional
obscured the deduced context.

Both classes are refactored to share declarations using an #ifdef,
to eliminate an ugly set of extra declarations needed when building
the documentation.

Copy and move class special members are added.

A new function message::base() is provided which returns the
message_headers portion of a message.
