Vinnie Falco 1eb673dd7d Add read, async_read for message_headers: 
fix #172, fix #173

This provides overloads of read and async_read to allow
reading message_headers objects.
 2017-07-20 08:12:13 -07:00
Vinnie Falco 8035dac88c Add write, async_write, operator<< for message_headers: 
fix #155

This adds overloads of write, async_write, and operator<<
for message_headers.

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.

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.

Andrew Whatson ed23fd5811 Fix unused parameter warnings and missing includes: 
fix #127

* Added beast::detail::ignore_unused based on boost::ignore_unused
* Added -Wextra compilation flag when building with gcc
* Fixed all unused parameter warnings with ignore_unused
* Fixed all missing includes when building each .hpp separately
 2017-07-20 08:12:13 -07:00
Vinnie Falco f3b22f74b2 Add headers_parser: 
This allows just the HTTP headers to be parsed, and
the choice of body to be deferred to a subsequent
call to parse.

Vinnie Falco 4ded6cff76 Fix handling of body_what::pause in basic_parser_v1 2017-07-20 08:12:13 -07:00

Vinnie Falco 83556937f6 Add on_body_what parser callback (API Change): 
These changes support parsing the headers separately from the body.

* on_headers now returns void
* on_body_what is a new required callback which returns body_what
 2017-07-20 08:12:13 -07:00
Vinnie Falco ac07d0c3ed Fix parser traits detection (API Change): 
basic_parser_v1 now requires that all callbacks appropriate
to the message are present and have the correct signatures.
Compile errors will result from compiling parsers which are
missing callbacks.
 2017-07-20 08:12:13 -07:00
Vinnie Falco e45a6418ee Tidy up documentation: 
fix #135

* Fix broken references
* Move doc debug headers to extras/
* Add rfc7230 utility classes to quick reference

Vinnie Falco a4d8a154b1 Refine message class hierarchy: 
Two new objects, request_headers and response_headers,
represent the portion of HTTP messages excluding the body.
 2017-07-20 08:12:13 -07:00
Vinnie Falco 056d6b94c2 Rework HTTP concepts (API Change): 
fix #139, fix #140

* Writer uses write instead of operator()
* Refactor traits to use void_t

* Add has_reader, has_writer, is_Reader, is_Writer
* More friendly compile errors on failed concept checks

Vinnie Falco f110e51dd1 HTTP Reader (API Change): 
fix #114, fix #117, fix #136

* Added init() to Reader requirements
* Reader must be nothrow constructible

  - The message passed on construction is filled in

Vinnie Falco 52be0dd06e Tidying: 
fix #85

* handler_alloc doc update
 2017-07-20 08:12:13 -07:00
Vinnie Falco 0eb3605232 Refactor base_parser_v1 callback traits: 
When the derived class provides a member function with the
corresponding callback name, but the signature is different,
a compile error will be generated instead of silently ignoring
the member function.
 2017-07-20 08:12:13 -07:00
Vinnie Falco 2106f364f6 Add pause option to on_headers interface:

Radoslaw Zarzynski bc665ee1ec Fix handling empty HTTP headers in parser_v1.hpp 
This patch rectifies flush() of beast::http::parser_v1
to properly handle the case when an HTTP header has
empty value.

Without the fix an empty-valued HTTP header is being
concatenated with the header directly following it.
This situation can be replicated using eg. curl:

  curl <url> -H "X-First;" -H "X-Second: bla"

What Beast's client would see is a single header named
as "X-FirstX-Second".

Vinnie Falco c17f467601 Restyle sources 2017-07-20 08:12:09 -07:00
Vinnie Falco 1947cb4e30 Fix rfc2616 Section 4.2 compliance: 
basic_headers no longer combines fields with the same name by appending
a comma and concatenating the two values together. This was breaking
certain header fields which expect each value to be distinct, such as
the "Set-Cookie" header.

Now the container behaves more like a multi set with respect to insertion
of multiple values with the same field name. Additional member functions
are provided to provide extra functionality.

Vinnie Falco 64206b5612 Qualify some calls: 
This fixes a problem where a call to read() is ambiguous because
the argument list contains objects from both boost::asio and
beast::http.

Users invoking read may need to do so fully qualified, by writing:
    beast::http::read(...);
 2017-07-20 08:12:07 -07:00
Vinnie Falco 62219add69 Initialize Writer in prepare: 
Writer requires a call to Writer::init to call content_length. This
changes prepare to correctly call init. A consequences is that
prepare can now throw unexpectedly for user-defined writers that
can fail their initialization.
 2017-07-20 08:12:07 -07:00
Vinnie Falco 589e18c199 rfc7230 compliance, limits, and tests for basic_parser_v1: 
New parser set_option function for controlling independent size limits
on headers and body. By default request and response parsers are set up
with reasonable limits to prevent resource exhaustion attacks.

* Parser adheres strictly to rfc7230
* Increased test coverage
* Headers and body maximum size limit options
 2017-07-20 08:12:07 -07:00
Vinnie Falco 6c30ee1a98 Rename concept to DynamicBuffer (API change): 
Conform to the Networking TS by renaming the Streambuf concept
to DynamicBuffer in all places. Values of types meeting the
requirements of DynamicBuffer are renamed to dynabuf.

See:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4478.html#requirements.dynamic_buffers

* Headers renamed
* Formal parameter names renamed
* Template argument types renamed
* Documentation updated

Vinnie Falco db68ce4d97 Add HTTP field value parsers: 
ext_list:
    Iterable container of comma separated extensions, where each extension
    is a token followed an optional list of semicolon delimited parameters,
    with each parameter consisting of a name / value pair. The value can
    be a token or quoted-string.

param_list:
    Iterable container of semicolon delimited parameters, where each parameter
    is a name / value pair. The value can be a token or quoted-string.

token_list
    Iterable container of comma delimited tokens.

* Remove obsolete rfc2616 functions

* Refactor and consolidate case-insensitive string helpers
