/// - If needed, use set_implicit_grant() to enable implicit grant flow.
/// 2. Build authorization URI with build_authorization_uri() and open this in web browser/control.

HEAD
0.5.1 - 2015-02-27
- Bug: Fixes an issue where some frame data was counted against the max header
size limit, resulting in connections that included a lot of frame data
immediately after the opening handshake to fail.
- Bug: Fix a type in the name of the set method for `max_http_body_size`. #406
Thank you jplatte for reporting.
0.5.0 - 2015-01-22
- BREAKING UTILITY CHANGE: Deprecated methods `http::parser::parse_headers`,
`http::response::parse_complete`, and `http::request::parse_complete` have
been removed.
- Security: Disabled SSLv3 in example servers.
- Feature: Adds basic support for accessing HTTP request bodies in the http
handler. #181
- Feature: Adds the ability to register a shutdown handler when using the
iostream transport. This provides a clean interface for triggering the shut
down of external sockets and other cleanup without hooking in to higher level
WebSocket handlers.
- Feature: Adds the ability to register a write handler when using the iostream
transport. This handler can be used to handle transport output in place of
registering an ostream to write to.
- Feature: Adds a new logging policy that outputs to syslog. #386 Thank you Tom
Hughes for submitting the initial version of this policy.
- Improvement: Message payload logging now prints text for text messages rather
than binary.
- Improvement: Overhaul of handshake state machine. Should make it impossible
for exceptions to bubble out of transport methods like `io_service::run`.
- Improvement: Overhaul of handshake error reporting. Fail handler error codes
will be more detailed and precise. Adds new [fail] and [http] logging channels
that log failed websocket connections and successful HTTP connections
respectively. A new aggregate channel package, `alevel::access_core`, allows
enabling connect, disconnect, fail, and http together. Successful HTTP
connections will no longer trigger a fail handler.
- Improvement: Ability to terminate connection during an http handler to cleanly
suppress the default outgoing HTTP response.
- Documentation: Add Sending & Receiving Messages step to chapter one of the
`utility_client` tutorial. Update `utility_client` example to match.
- Cleanup: Removes unused files & STL includes. Adds required STL includes.
Normalizes include order.
- Bug: Fixes a fatal state error when a handshake response is completed
immediately after that handshake times out. #389
- Bug: MinGW fixes; C++11 feature detection, localtime use. #393 Thank you
Schebb for reporting, code, and testing.
- Bug: Fixes an issue where `websocketpp::exception::what()` could return an out
of scope pointer. #397 Thank you fabioang for reporting.
- Bug: Fixes an issue where endpoints were not reset properly after a call to
`endpoint::listen` failed. #390 Thank you wyyqyl for reporting.
0.4.0 - 2014-11-04
- BREAKING API CHANGE: All WebSocket++ methods now throw an exception of type
`websocketpp::exception` which derives from `std::exception`. This normalizes
all exception types under the standard exception hierarchy and allows
WebSocket++ exceptions to be caught in the same statement as others. The error
code that was previously thrown is wrapped in the exception object and can be
accessed via the `websocketpp::exception::code()` method.
- BREAKING API CHANGE: Custom logging policies have some new required
constructors that take generic config settings rather than pointers to
std::ostreams. This allows writing logging policies that do not involve the
use of std::ostream. This does not affect anyone using the built in logging
policies.
- BREAKING UTILITY CHANGE: `websocketpp::lib::net::htonll` and
`websocketpp::lib::net::ntohll` have been prefixed with an underscore to avoid
conflicts with similarly named macros in some operating systems. If you are
using the WebSocket++ provided 64 bit host/network byte order functions you
will need to switch to the prefixed versions.
- BREAKING UTILITY CHANGE: The signature of `base64_encode` has changed from
`websocketpp::base64_encode(unsigned char const *, unsigned int)` to
`websocketpp::base64_encode(unsigned char const *, size_t)`.
- BREAKING UTILITY CHANGE: The signature of `sha1::calc` has changed from
`websocketpp::sha1::calc(void const *, int, unsigned char *)` to
`websocketpp::sha1::calc(void const *, size_t, unsigned char *)`
- Feature: Adds incomplete `minimal_server` and `minimal_client` configs that
can be used to build custom configs without pulling in the dependencies of
`core` or `core_client`. These configs will offer a stable base config to
future-proof custom configs.
- Improvement: Core library no longer has std::iostream as a dependency.
std::iostream is still required for the optional iostream logging policy and
iostream transport.
- Bug: C++11 Chrono support was being incorrectly detected by the `boost_config`
header. Thank you Max Dmitrichenko for reporting and a patch.
- Bug: use of `std::put_time` is now guarded by a unique flag rather than a
chrono library flag. Thank you Max Dmitrichenko for reporting.
- Bug: Fixes non-thread safe use of std::localtime. #347 #383
- Compatibility: Adjust usage of std::min to be more compatible with systems
that define a min(...) macro.
- Compatibility: Removes unused parameters from all library, test, and example
code. This assists with those developing with -Werror and -Wunused-parameter
#376
- Compatibility: Renames ntohll and htonll methods to avoid conflicts with
platform specific macros. #358 #381, #382 Thank you logotype, unphased,
svendjo
- Cleanup: Removes unused functions, fixes variable shadow warnings, normalizes
all whitespace in library, examples, and tests to 4 spaces. #376
0.3.0 - 2014-08-10
- Feature: Adds `start_perpetual` and `stop_perpetual` methods to asio transport
These may be used to replace manually managed `asio::io_service::work` objects
- Feature: Allow setting pong and handshake timeouts at runtime.
- Feature: Allows changing the listen backlog queue length.
- Feature: Split tcp init into pre and post init.
- Feature: Adds URI method to extract query string from URI. Thank you Banaan
for code. #298
- Feature: Adds a compile time switch to asio transport config to disable
certain multithreading features (some locks, asio strands)
- Feature: Adds the ability to pause reading on a connection. Paused connections
will not read more data from their socket, allowing TCP flow control to work
without blocking the main thread.
- Feature: Adds the ability to specify whether or not to use the `SO_REUSEADDR`
TCP socket option. The default for this value has been changed from `true` to
`false`.
- Feature: Adds the ability to specify a maximum message size.
- Feature: Adds `close::status::get_string(...)` method to look up a human
readable string given a close code value.
- Feature: Adds `connection::read_all(...)` method to iostream transport as a
convenience method for reading all data into the connection buffer without the
end user needing to manually loop on `read_some`.
- Improvement: Open, close, and pong timeouts can be disabled entirely by
setting their duration to 0.
- Improvement: Numerous performance improvements. Including: tuned default
buffer sizes based on profiling, caching of handler binding for async
reads/writes, non-malloc allocators for read/write handlers, disabling of a
number of questionably useful range sanity checks in tight inner loops.
- Improvement: Cleaned up the handling of TLS related errors. TLS errors will
now be reported with more detail on the info channel rather than all being
`tls_short_read` or `pass_through`. In addition, many cases where a TLS short
read was in fact expected are no longer classified as errors. Expected TLS
short reads and quasi-expected socket shutdown related errors will no longer
be reported as unclean WebSocket shutdowns to the application. Information
about them will remain in the info error channel for debugging purposes.
- Improvement: `start_accept` and `listen` errors are now reported to the caller
either via an exception or an ec parameter.
- Improvement: Outgoing writes are now batched for improved message throughput
and reduced system call and TCP frame overhead.
- Bug: Fix some cases of calls to empty lib::function objects.
- Bug: Fix memory leak of connection objects due to cached handlers holding on to
reference counted pointers. #310 Thank you otaras for reporting.
- Bug: Fix issue with const endpoint accessors (such as `get_user_agent`) not
compiling due to non-const mutex use. #292 Thank you logofive for reporting.
- Bug: Fix handler allocation crash with multithreaded `io_service`.
- Bug: Fixes incorrect whitespace handling in header parsing. #301 Thank you
Wolfram Schroers for reporting
- Bug: Fix a crash when parsing empty HTTP headers. Thank you Thingol for
reporting.
- Bug: Fix a crash following use of the `stop_listening` function. Thank you
Thingol for reporting.
- Bug: Fix use of variable names that shadow function parameters. The library
should compile cleanly with -Wshadow now. Thank you giszo for reporting. #318
- Bug: Fix an issue where `set_open_handshake_timeout` was ignored by server
code. Thank you Robin Rowe for reporting.
- Bug: Fix an issue where custom timeout values weren't being propagated from
endpoints to new connections.
- Bug: Fix a number of memory leaks related to server connection failures. #323
#333 #334 #335 Thank you droppy and aydany for reporting and patches.
reporting.
- Compatibility: Fix compile time conflict with Visual Studio's MIN/MAX macros.
Thank you Robin Rowe for reporting.
- Documentation: Examples and test suite build system now defaults to clang on
OS X
0.3.0-alpha4 - 2013-10-11
- HTTP requests ending normally are no longer logged as errors. Thank you Banaan
for reporting. #294
- Eliminates spurious expired timers in certain error conditions. Thank you
Banaan for reporting. #295
- Consolidates all bundled library licenses into the COPYING file. #294
- Updates bundled sha1 library to one with a cleaner interface and more
straight-forward license. Thank you lotodore for reporting and Evgeni Golov
for reviewing. #294
- Re-introduces strands to asio transport, allowing `io_service` thread pools to
be used (with some limitations).
- Removes endpoint code that kept track of a connection list that was never used
anywhere. Removes a lock and reduces connection creation/deletion complexity
from O(log n) to O(1) in the number of connections.
- A number of internal changes to transport APIs
- Deprecates iostream transport `readsome` in favor of `read_some` which is more
consistent with the naming of the rest of the library.
- Adds preliminary signaling to iostream transport of eof and fatal transport
errors
- Updates transport code to use shared pointers rather than raw pointers to
prevent asio from retaining pointers to connection methods after the
connection goes out of scope. #293 Thank you otaras for reporting.
- Fixes an issue where custom headers couldn't be set for client connections
Thank you Jerry Win and Wolfram Schroers for reporting.
- Fixes a compile error on visual studio when using interrupts. Thank you Javier
Rey Neira for reporting this.
- Adds new 1012 and 1013 close codes per IANA registry
- Add `set_remote_endpoint` method to iostream transport.
- Add `set_secure` method to iostream transport.
- Fix typo in .gitattributes file. Thank you jstarasov for reporting this. #280
- Add missing locale include. Thank you Toninoso for reporting this. #281
- Refactors `asio_transport` endpoint and adds full documentation and exception
free varients of all methods.
- Removes `asio_transport` endpoint method cancel(). Use `stop_listen()` instead
- Wrap internal `io_service` `run_one()` method
- Suppress error when trying to shut down a connection that was already closed
0.3.0-alpha3 - 2013-07-16
- Minor refactor to bundled sha1 library
- HTTP header comparisons are now case insensitive. #220, #275
- Refactors URI to be exception free and not use regular expressions. This
eliminates the dependency on boost or C++11 regex libraries allowing native
C++11 usage on GCC 4.4 and higher and significantly reduces staticly built
binary sizes.
- Updates handling of Server and User-Agent headers to better handle custom
settings and allow suppression of these headers for security purposes.
- Fix issue where pong timeout handler always fired. Thank you Steven Klassen
for reporting this bug.
- Add ping and pong endpoint wrapper methods
- Add `get_request()` pass through method to connection to allow calling methods
specific to the HTTP policy in use.
- Fix issue compile error with `WEBSOCKETPP_STRICT_MASKING` enabled and another
issue where `WEBSOCKETPP_STRICT_MASKING` was not applied to incoming messages.
Thank you Petter Norby for reporting and testing these bugs. #264
- Add additional macro guards for use with boost_config. Thank you breyed
for testing and code. #261
0.3.0-alpha2 - 2013-06-09
- Fix a regression that caused servers being sent two close frames in a row
to end a connection uncleanly. #259
- Fix a regression that caused spurious frames following a legitimate close
frames to erroneously trigger handlers. #258
- Change default HTTP response error code when no http_handler is defined from
500/Internal Server Error to 426/Upgrade Required
- Remove timezone from logger timestamp to work around issues with the Windows
implementation of strftime. Thank you breyed for testing and code. #257
- Switch integer literals to char literals to improve VCPP compatibility.
Thank you breyed for testing and code. #257
- Add MSVCPP warning suppression for the bundled SHA1 library. Thank you breyed
for testing and code. #257
0.3.0-alpha1 - 2013-06-09
- Initial Release
