fix#123fix#154fix#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
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.
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.
fix#261
This fixes a rare condition when responding to a ping or
close frame where the wr_block_ stream variable is not
correctly set for a short window of time.
fix#257
This fixes a problem when doing split parsing (header then body).
The problem arises when the first buffer passed to the header
parser contains exactly the full header and nothing more. The
symptom is that when parsing the body, the parse will erroneously
be considered complete.
* Add handler_ptr test and increase coverage
* Add test for prepare_buffer
* Move is_call_possible tests to a .cpp file
* Tidy up docs and declarations
