HEAD
0.8.2 - 2020-04-19
- Examples: Update print_client_tls example to remove use of deprecated
OpenSSL functions.
- Compatibility: Removes the use of make_shared in a number of cases where
it would be incompatible with newer versions of ASIO. Thank you Stefan
Floeren for the patch. #810 #814 #862 #843 #794 #808
- CMake: Update cmake installer to better handle dependencies when using
g++ on MacOS. Thank you Luca Palano for reporting and a patch. #831
- CMake: Update cmake installer to use a variable for the include directory
improving the ability of the install to be customized. THank you Schrijvers
Luc and Gianfranco Costamanga for reporting and a patch. #842
0.8.1 - 2018-07-16
Note: This release does not change library behavior. It only corrects issues
in the installer and test system.
- Test Suite: Adjust test suite to match behavior introduced in 0.8.0. Thank
you Gianfranco Costamagna for reporting and a patch. #731
- CMake: Update cmake installer to only install library files globally.
Thank you Gianfraco Costamanga for reporting and a patch. #732
0.8.0 - 2018-07-12
- Examples: Add `print_client` example. This demonstrates a minimal non-TLS
client that connects to a server and prints out the messages it receives.
- Examples: Add `print_client_tls` example. This demonstrates a minimal TLS
client, including basic support via Asio+OpenSSL for certificate chain
and hostname verification.
- Feature: Add getter for all headers to the HTTP parsers. This allows a
wrapping library to enumerate all headers to send upstream. Thank you Jupp
Müller for reporting and an initial pull request.
- Improvement: Move the `socket_init_handler` to execute as a part of `init_asio`
rather than connection `pre_init`. This allows setting of socket options prior
to the bind/listen/accept system calls. Thank you ChristianRobl3D for
reporting #530.
- Improvement: Timers in transport integration tests should only fail if their
own test times out, rather than any test. #643 Thank you Alex Korotkin for
reporting and a patch.
- Improvement: Preserve transport layer error codes in more cases, particularly
during calls to `endpoint::listen`. #652 Thank you vadz for reporting and
patches.
- Compatibility: Make sure the chrono library used by Boost/Asio is in sync
with what the websocketpp is using. Thank you Flow86 for reporting and a
patch.
- Compatibility: Update `telemetry_client` to use a slightly more cross platform
method of sleeping. Should work on windows now. Thank you Meir Yanovich for
reporting.
- Compatibility: Updated permessage-deflate support to reflect that the zlib
library does not actually support a sliding window size of 256 bits.
WebSocket++ will no longer negotiate 256 bit deflate windows. If the user
of the library tries to request a 256 bit window a 512 bit window will be
specified instead (This was the previous behavior). #596 #653 Thank you
Vinnie Falco and Gianfranco Costamagna for reporting.
- Compatibility: Better error handling and logging in cases where extension
requests parse correctly but negotiation fails.
- Compatibility: Removed custom handling of `SSL_R_SHORT_READ` error condition.
This error code no longer exists in modern versions of OpenSSL and causes
a build error. It wasn't being used for anything particularly important
(slightly improving error reporting) and there isn't a great replacement.
#599 Thank you Gianfranco Costamagna for reporting.
- Compatibility: Add missing `<stdint>` headers. Fixes issues with g++ 5.4.0.
#638 Thank you Alex Korotkin for reporting and a patch.
- Compatibility: Remove the use of `std::auto_ptr` and `std::binary_function`
from builds with C++11 or later. These features are deprecated and were
removed entirely in C++17. This change allows building WebSocket++ on
C++17 compilers. #592 Thank you Michal Fojtak for reporting and a patch
- Compatibility: Add 1014 close code and adds missing descriptions for codes
1012 and 1013. #589 Thank you jbwdevries and ronneke1996 for reporting and
patches.
- Compatibility: Add hooks to support `mingw-std-threads` C++11 thread and mutex
polyfill library as an alternative to Boost. #608 Thank you Peter Taylor for
reporting and an initial patch.
- Compatibility: Changed the handshake connection token to 'Upgrade' from
'upgrade'. Technically this header is supposed to be processed case
insensitively. In practice, there are browsers (such as Edge) that don't do
this and they tend to use the uppercase value used as an example in RFC6455.
Thank you Johann Bauer for reporting and a patch. #727
- Bug: Store loggers in shared pointers to avoid crashes related to connections
trying to write logs entries after their respective endpoint has been
deallocated. Thank you Thalhammer for reporting and Jupp Müller for the
patch. #539 #501
- Bug: Change default listen backlog from 0 to `socket_base::max_connections`.
#549. Thank you derwassi and zwelab for reporting and na1pir for providing
access to hardware to debug the issue.
- Bug: Fix a crash in the accept loop when `get_connection` fails. #551 Thank you
Walter Gray for a patch.
- Bug/Documentation: Fix incorrect example code that used
`websocketpp::lib::error_code` instead of `websocketpp::exception`. Thank you
heretic13 for reporting
- Bug: Fix uninitialized shared pointer in Asio transport test suite. #647
Thank you Alex Korotkin for reporting and a patch.
- Bug: Fix a thread safety issue in the permessage-deflate extension that
caused message corruption when sending compressed messages from a different
thread than the main I/O thread. #615 Thank you KyleNyenhuis and Pieter De
Gendt for reporting and a patch.
- Bug: Fix an undefined behavior issue performing a 64 bit wide shift on a 64
bit value. #636 Thank you Gregor Jasny for reporting and a patch
- Bug: Fix some compile issues with ASIO_STANDALONE. #662 #665 Thank you
chronoxor and Guillaume Egles for reporting and patches.
0.7.0 - 2016-02-22
- MINOR BREAKING SOCKET POLICY CHANGE: Asio transport socket policy method
`cancel_socket` will now return `lib::asio::error_code` instead of `void`.
Custom Asio transport socket policies will need to be updated accordingly.
This does not affect anyone using the bundled socket policies.
- Feature: Basic support for the permessage-deflate extension. #344
- Feature: Allow accessing the local endpoint when using the Asio transport.
This allows inspection of the address and port in cases where they are chosen
by the operating system rather than the user. Thank you Andreas Weis and
Muzahid Hussain for reporting and related code. #458
- Feature: Add support for subprotocols in Hybi00. Thank you Lukas Obermann
for reporting and a patch. #518
- Feature: Adds `tcp_pre_bind handler` to Asio transport. This allows setting
arbitrary socket options after the listen acceptor has been created but before
the socket bind has been performed. #634 #439 Thank you Gregor Jasny for
the patch.
- Improvement: Better automatic std::chrono feature detection for Visual Studio
- Improvement: Major refactoring to bundled CMake build system. CMake can now be
used to build all of the examples and the test suite. Thank you Thijs Wenker
for a significant portion of this code. #378, #435, #449
- Improvement: In build environments where `lib::error_code` and
`lib::asio::error_code` match (such as using `boost::asio` with
`boost::system_error` or standalone asio with `std::system_error`, transport
errors are passed through natively rather than being reported as a translated
`pass_through` error type.
- Improvement: Add a `get_transport_error` method to Asio transport connections
to allow retrieving a machine readable native transport error.
- Improvement: Add `connection::get_response`, `connection::get_response_code`,
and `connection::get_response_msg` methods to allow accessing additional
information about the HTTP responses that WebSocket++ sends. #465 Thank you
Flow86 for reporting.
- Improvement: Removes use of empty strings ("") in favor of `string::clear()`
and `string::empty()`. This avoids generating unnecessary temporary objects.
#468 Thank you Vladislav Yaroslavlev for reporting and a patch.
- Documentation: Adds an example demonstrating the use of external `io_service`
- Documentation: Adds a simple `echo_client` example.
- Documentation: Begins migration of the web based user manual into Doxygen.
- Bug: Fix memory leak when `init_asio` produces an error. #454 Thank you Mark
Grimes for reporting and fixing.
- Bug: Fix crash when processing a specially crafted HTTP header. Thank you Eli
Fidler for reporting, test cases, and a patch. #456
- Bug: Fix an issue where standalone Asio builds that use TLS would not compile
due to lingering boost code. #448 Thank you mjsp for reporting
- Bug: Fix an issue where canceling a socket could throw an exception on some
older Windows XP platforms. It now prints an appropriate set of log messages
instead. Thank you Thijs Wenker for reporting and researching solutions. #460
- Bug: Fix an issue where deferred HTTP connections that start sending a very
long response before their HTTP handler ends would result in a second set of
HTTP headers being injected into the output. Thank you Kevin Smith for
reporting and providing test case details. #443
- Bug: Fix an issue where the wrong type of strand was being created. Thank you
Bastien Brunnenstein for reporting and a patch. #462
- Bug: Fix an issue where TLS includes were broken for Asio Standalone builds.
Thank you giachi and Bastien Brunnenstein for reporting. #491
- Bug: Remove the use of cached read and write handlers in the Asio transport.
This feature caused memory leaks when the `io_service` the connection was
running on was abruptly stopped. There isn't a clean and safe way of using
this optimization without global state and the associated locks. The locks
perform worse. Thank you Xavier Gibert for reporting, test cases, and code.
Fixes #490.
- Bug: Fix a heap buffer overflow when checking very short URIs. Thank you
Xavier Gibert for reporting and a patch #524
- Compatibility: Fixes a number of build & config issues on Visual Studio 2015
- Compatibility: Removes non-standards compliant masking behavior. #395, #469
- Compatibility: Replace deprecated use of `auto_ptr` on systems where
`unique_ptr` is available.
0.6.0 - 2015-06-02
- MINOR BREAKING TRANSPORT POLICY CHANGE: Custom transport policies will now be
required to include a new method `void set_uri(uri_ptr u)`. An implementation
is not required. The stub transport policy includes an example stub method
that can be added to any existing custom transport policy to fulfill this
requirement. This does not affect anyone using the bundled transports or
configs.
- MINOR BREAKING SOCKET POLICY CHANGE: Custom asio transport socket policies
will now be required to include a new method `void set_uri(uri_ptr u)`. Like
with the transport layer, an implementation is not required. This does not
affect anyone using the bundled socket policies.
- MINOR BREAKING DEPENDENCY CHANGE: When using Boost versions greater than or
equal to 1.49 in C++03 mode, `libboost-chrono` is needed now instead of
`libboost-date_time`. Users with C++11 compilers or using Boost versions 1.48
and earlier are not affected. Note: This change affects the bundled unit test
suite.
- Feature: WebSocket++ Asio transport policy can now be used with the standalone
version of Asio (1.8.0+) when a C++11 compiler and standard library are
present. This means that it is possible now to use WebSocket++'s Asio
transport entirely without Boost. Thank you Robert Seiler for proof of concept
code that was used as a guide for this implementation. Fixes #324
- Feature: Adds a vectored/scatter-gather write handler to the iostream
transport.
- Feature: Adds the ability to defer sending an HTTP response until sometime
after the `http_handler` is run. This allows processing of long running http
handlers to defer their response until it is ready without blocking the
network thread. references #425
- Improvement: `echo_server_tls` has been update to demonstrate how to configure
it for Mozilla's recommended intermediate and modern TLS security profiles.
- Improvement: `endpoint::set_timer` now uses a steady clock provided by
`boost::chrono` or `std::chrono` where available instead of the non-monotonic
system clock. Thank you breyed for reporting. fixes #241
- Improvement: Outgoing TLS connections to servers using the SNI extension to
choose a certificate will now work. Thank you moozzyk for reporting.
Fixes #400
- Improvement: Removes an unnecessary mutex lock in `get_con_from_hdl`.
- Cleanup: Asio transport policy has been refactored to remove many Boost
dependencies. On C++03 compilers the `boost::noncopyable` dependency has been
removed and the `boost::date_time` dependency has been replaced with the newer
`boost::chrono` when possible. On C++11 compilers the `boost::aligned_storage`
and `boost::date_time` dependencies are gone, replaced with equivalent C++11
standard library features.
- Bug: Fixes a potential dangling pointer and inconsistent error message
handling in `websocketpp::exception`. #432 Thank you Tom Swirly for the fix.
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 typo 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

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

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.

/** \page reference.config Config Reference
WebSocket++ uses a config template parameter to supply a number of compile type policy types and default numerical values for buffer sizes, timeouts, security behavior, etc. Swapping policies allows changing certain core library behavior designed to be pluggable.
A custom config can be made standalone or can subclass one of the bundled configs and just override a few things.
__Example__
```
// some config options may require additional includes or dependencies.
// syslog logging policy, for example, requires <syslog.h>,
// the permessage deflate settings require zlib.
#include <websocketpp/logger/syslog.hpp>
#include <websocketpp/extensions/permessage_deflate/enabled.hpp>
// Custom server config based on bundled asio config
struct custom_server_config : public websocketpp::config::asio {
// Replace default stream logger with a syslog logger
typedef websocketpp::log::syslog<concurrency_type, websocketpp::log::elevel> elog_type;
typedef websocketpp::log::syslog<concurrency_type, websocketpp::log::alevel> alog_type;
// Reduce read buffer size to optimize for small messages
static const size_t connection_read_buffer_size = 1024;
// enable permessage_compress extension
struct permessage_deflate_config {};
typedef websocketpp::extensions::permessage_deflate::enabled
<permessage_deflate_config> permessage_deflate_type;
};
typedef websocketpp::server<custom_server_config> server_endpoint_type;
```
Core Config Options
-------------------
### Policies
Policies are classes used to allow clean swapping of behavior without changing the core library
| Typedef Name | Effect |
| ------------------------- | -------------------------------------- |
| concurrency_type | Concurrency policy |
| elog_type | Error logger type |
| alog_type | Access logger type |
| request_type | HTTP request type |
| response_type | HTTP response type |
| message_type | Type to deliver recieved messages |
| con_msg_manager_type | Connection level message manager |
| endpoint_msg_manager_type | Endpoint level message manager |
| rng_type | Random Number Generation policy |
| transport_type | Transport policy to use |
| endpoint_base | User overridable Endpoint base class |
| connection_base | User overridable Connection base class |
### Timeouts Values
These represent the length of time (in ms) before the given operation is aborted
| Field | Type | Default | Operation |
| ----------------------- | ---- | ------- | --------------------------- |
| timeout_open_handshake | long | 5000 | Opening handshake |
| timeout_close_handshake | long | 5000 | Closing handshake |
| timeout_pong | long | 5000 | No pong recieved after ping |
### Performance tuning
| Field | Type | Default | Meaning |
| --------------------------- | ------ | -------- | ------------------------------------------------------------------ |
| connection_read_buffer_size | size_t | 16384 | Size of the per-connection read buffer |
| enable_multithreading | bool | true | Disabling may reduce locking overhead for single threaded programs |
#### Connection Read Buffer
Each connection has an internal buffer of this size. A larger value will result in fewer trips through the library and less CPU overhead at the expense of increased memory usage per connection.
If your application primarily deals in very large messages you may want to try setting this value higher.
If your application has a lot of connections or primarily deals in small messages you may want to try setting this smaller.
### Security settings
| Field | Type | Default | Effect |
| ---------------------- | ------ | ------- | -------------------------------------- |
| drop_on_protocol_error | bool | false | Omit close handshake on protocol error |
| silent_close | bool | false | Don't return close codes or reasons |
| max_message_size | size_t | 32MB | WebSocket max message size limit |
| max_http_body_size | size_t | 32MB | HTTP Parser's max body size limit |
#### Drop on protocol error
Drop connections on protocol error rather than sending a close frame. Off by default. This may result in legitimate messages near the error being dropped as well. It may free up resources otherwise spent dealing with misbehaving clients.
#### Silent Close
Silence close suppresses the return of detailed connection close information during the closing handshake. This information is useful for debugging and presenting useful errors to end users but may be undesirable for security reasons in some production environments. Close reasons could be used by an attacker to confirm that the endpoint is out of resources or be used to identify the WebSocket implementation in use.
Note: this will suppress *all* close codes, including those explicitly sent by local applications.
#### Max message size
Default value for the processor's maximum message size. Maximum message size determines the point at which the library will drop a connection with the message_too_big protocol error.
#### Max HTTP header size
Maximum body size determines the point at which the library will abort reading an HTTP message body and return the 413/request entity too large error.

/** \page faq FAQ
## General Library Usage
### Can a handler be changed after a connection is established? Can one be removed?
Yes, but not globally.
Handlers assigned to endpoints will be automatically copied to the connections created by that endpoint. Changing a handler on an endpoint will only affect future connections.
Once a particular connection is created, it's handlers can be changed individually by calling the `set_*_handler` methods. Once changed, all future events of that type for that connection will use the new handler.
To remove a handler that was previously set, call the set method with `nullptr` or `NULL`.
### Can I reject or conditionally accept a connection
Yes. The `validate` handler is called after the initial handshake has been recieved but before WebSocket++ has responded. This gives you the opportunity to inspect the incoming connection request, its headers, origin, subprotocols, and the remote endpoint IP. Return `true` from the validate handler to accept the connection and `false` to reject it.
To set a custom HTTP error message for your rejection, use `websocketpp::connection::set_status` and (optionally) `websocketpp::connection::set_body()` to set the HTTP status code and error message body text. If you do not set body text a message will be generated automatically based on the status code.
### How do I negotiate subprotocols?
WebSocket connections may offer a particular subprotocol they want to use. The WebSocket protocol does not define the meaning or interpretation of the subprotocol. This interpretation is left up to the individual application endpoints.
WebSocket++ servers can read the requested subprotocols during the `validate` handler by calling `websocketpp::connection::get_requested_subprotocols`. The list is ordered by client priority. You may optionally choose one of these subprotocols with `websocketpp::connection::select_subprotocol`. The handshake will then complete and let the client know which one was chosen. If you do not choose any, the "blank"/empty/none subprotocol will be used.
WebSocket++ clients can add a subprotocol to an outgoing connection by calling `websocketpp::connection::add_subprotocol` before calling `websocketpp::client::connect`. The order of adding will be interpreted as the order of preference.
In both caases, after the connection has been established, the selected subprotocol is available via the `websocketpp::connection::get_subprotocol` method.
Note: some browsers will allow the connection to continue if they requested a subprotocol and your server doesn't select one. Others will reject the connection.
### How do I cleanly exit an Asio transport based program
The Asio transport based clients and servers use the Asio library's underlying `io_service` to handle asyncronous networking operations. The standard behavior of the io_service is to run until there are no async operations left and then return. WebSocket++, when using the Asio transport, behaves like a standard Asio application. If you want your WebSocket++/Asio based program to stop network operations and cleanly close all sockets you will want to do the following:
- For servers, call `websocketpp::transport::asio::endpoint::stop_listening` to initiate the closing of the server listening socket.
- For clients, if you have engaged perpetual mode with `websocketpp::transport::asio::endpoint::start_perpetual`, disable it with `websocketpp::transport::asio::endpoint::stop_perpetual`.
- For both, run `websocketpp::endpoint::close` or `websocketpp::connection::close` on all currently outstanding connections. This will initiate the WebSocket closing handshake for these connections
- Wait. Asio is asyncronous. When the calls to the above methods (stop_listening, close, etc) complete the server *will still be listening*, the connections *will still be active* until the io_service gets around to asyncronously processing the socket and WebSocket protocol closing handshakes. The `io_service::run` method will exit cleanly and automatically when all operations are complete.
__WARNING__: Asio's `io_service` has a method called `stop`. WebSocket++ wraps this method as `websocketpp::transport::asio::endpoint::stop`. While this operation has a benign sounding name, it is a powerful and destructive operation that should only be used in special cases. If you are using `io_service::stop` or `endpoint::stop` without a very good reason your program is likely broken and may exhibit erratic behavior. Specifically, `io_service::stop` stops the processing of events entirely. This does not give current operations (such as socket closing handshakes) the opportunity to finish. It will leave your sockets in a dangling state that may invoke operating system level timeouts or other errors.
__Special cases__:
- If your client uses the `start_perpetual` method it will prevent the io_service from exiting even if it has nothing to do. This is useful if you want a client endpoint to idle in the background to allow new connections to be formed on demand rather than generating a new endpoint for each.
- If you are using an external io_service and/or are placing non-WebSocket++ operations on the `io_service` those operations may keep the `io_service` open even after all WebSocket++ operations have completed.
- If you are using `poll`/`poll_one`/`run_one` or otherwise manually driving the `io_service` event loop you may need to adjust usage to make sure you are correctly recognizing the "done with work" and "not done but idling / `io_service::work`" cases.
### Is there a way to check the validity of a `connection_hdl`?
Sometimes, not generally though, because there isn’t a way to check if a TCP connection is valid.
You can try upgrading your hdl to a full connection_ptr using `websocketpp::endpoint::get_con_from_hdl`. If this fails, the hdl is definitely invalid. If it succeeds it may or may not be. The only way to tell definitively is to try and send something (either a message or a ping).
If you handle errors from methods like send, ping, close, etc correctly then you shouldn’t have to worry about accidentally sending to dead connections. The send/ping/pong/close methods will set or throw a specific error in the case that you tried to send something but the connection was closed/gone/etc.
### How do I fix the "address is in use" error when trying to restart my server?
Normally, for security purposes, operating systems prevent programs from listening on sockets created by other programs. When your program crashes and restarts, the new instance is a different program from the perspective of the operating system. As such it can’t listen on the socket address/port that the previous program was using until after a timeout occurs to make sure the old program was done with it.
The first step for handling this is to make sure that you provide a method (signal handler, admin websocket message, etc) to perform a clean server shutdown. There is a question elsewhere in this FAQ that describes the steps necessary for this.
The clean close strategy won't help in the case of crashes or other abnormal closures. An option to consider for these cases is the use of the SO_REUSEADDR socket option. This instructs the OS to not request an exclusive lock on the socket. This means that after your program crashes the replacement you start can immediately listen on that address/port combo again.
__Please note__: how this works exactly depends on your operating system. Additionally, not exclusively locking your listening socket could allow hijacking by other programs if you are running in a shared resource environment. For development this is generally no problem. For a production environment, think carefully about the security model. `websocketpp::transport::asio::endpoint::set_reuse_addr` is the method to do this. You must specify this setting before calling `websocketpp::transport::asio::endpoint::listen`.
### How do I send and recieve binary messages?
When supported by the remote endpoint, WebSocket++ allows reading and sending messages in the two formats specified in RFC6455, UTF8 text and binary. WebSocket++ performs UTF8 validation on all outgoing text messages to ensure that they meet the specification. Binary messages do not have any additional processing and their interpretation is left entirely to the library user.
To determine the type of an incoming message, use `websocketpp::message_buffer::message::get_opcode`. The relevant return values are `websocketpp::frame::opcode::text` and `websocketpp::frame::opcode::binary`. There is no difference in how payloads are retrieved between these modes, only in how WebSocket++ validated the contents and how the library user is to interpret the data.
To specify the type of an outgoing message, use the frame opcode values listed above as the second op parameter for `websocketpp::connection::send`. There are two relevant overloads of send. One that takes a `std::string` and defaults to op=text. The other that takes a `void const *` and a `size_t` length and defaults to op=binary. Note: You can send binary messages via the string overload and text messages via the void * overload. In the case that you are manually building a message buffer rather than using the automatic send member functions, you can pass the opcode in as a parameter to the message buffer constructor or user the `websocketpp::message_buffer::message::set_opcode` member function to set or re-set it later.
## Dependency Management
### Can WebSocket++ be used without Boost?
Yes. WebSocket++ only uses Boost features as polyfills for C++11 language features and libraries. If you have a C++11 compiler and standard library you can use WebSocket++ without Boost. In most cases setting your build environment to use the C++11 (or later) language dialect is sufficient to enable this mode of use.
With less common compilers (and sometimes very recently release compilers) there may be specific issues with certain libraries that aren't automatically detected by the library. For these situations there are additional defines available to fine tune which C++11 libraries and features are used. TODO: more details about them.
For the iostream/raw transport the C++11 standard library is sufficient. For the Asio based transports, there is no C++11 library that provides the networking capabilaties that Asio does. As such even with a C++11 build system, you will need a standalone copy of Asio to use if Boost Asio is not available.
MinGW users who want to avoid Boost should also consult the nearby question about MinGW compatibility.
### Can WebSocket++ be used with standalone Asio
Yes. The process is the same as used with standalone Asio itself. Define `ASIO_STANDALONE` before including Asio or WebSocket++ headers. You will need to download a copy of the Asio headers separately (http://www.think-async.com) and make sure they are in your build system's include path.
### Can WebSocket++ be used without TLS or OpenSSL?
Yes. When using the iostream/raw transport, there are no TLS features and OpenSSL is not required. When using the Asio transport TLS features are optional. You only need OpenSSL if you want to use TLS. You can only make or recieve encrypted connections (https/wss) if you have enabled TLS features.
Whether an Asio endpoint uses TLS or not is determined by its config template parameter. The default bundled `websocketpp::config::asio` and `websocketpp::config::asio_client` configs do not support TLS, the `websocketpp::config::asio_tls` and `websocketpp::config::asio_tls_client` do.
The `<websocketpp/config/asio.hpp>` and `<websocketpp/config/asio_client.hpp>` headers will include both the TLS and non-TLS varients of their respective configs and require the presence of OpenSSL. The `<websocketpp/config/asio_no_tls.hpp>` and `<websocketpp/config/asio_no_tls_client.hpp>` headers will include only the non-TLS configs and do not require OpenSSL.
### Build issues with TLS on recent versions of OS X
Mac OS X ships a severely outdated version of the OpenSSL library. To securely use TLS with WebSocket++ on OS X you will need to install a modern version of OpenSSL via homebrew or compiling from source.
### Can WebSocket++ be used with MinGW
Generally, yes. Note that in C++11 mode MinGW does not currently support the C++11 STL `<thread>` library. WebSocket++ requires a thread/mutex library. Options include Boost thread (the default when a compatible C++11 `<thread>` can't be found) or `mingw-std-threads` (https://github.com/meganz/mingw-std-threads) by including those headers and defining `_WEBSOCKETPP_MINGW_THREAD_`.
## Compression
### How do I use permessage-deflate in version 0.6.0-permessagedeflate and 0.7.0?
These versions of the library require a custom config to use the permessage-deflate extension. Here is a minimal example of such a custom config. You can also integrate these lines into an existing custom config.
Note that in these versions there is no fine grained control over which connections are compressed or not. Clients will request compression with the default settings and use it if the server supports it. Servers will accept whatever parameters clients request.
Outgoing messages by default will be compressed if compression was auto-negotiated during the handshake. There is an option to force a specific message to be sent uncompressed even if compression was negotiated. This may be useful for sending data that you know to be compressed already (images, zip files, etc).
__Server Example__
```
#include <websocketpp/extensions/permessage_deflate/enabled.hpp>
struct deflate_server_config : public websocketpp::config::asio {
// ... additional custom config if you need it for other things
/// permessage_compress extension
struct permessage_deflate_config {};
typedef websocketpp::extensions::permessage_deflate::enabled
<permessage_deflate_config> permessage_deflate_type;
};
typedef websocketpp::server<deflate_server_config> server_endpoint_type;
```
__Client Example__
```
#include <websocketpp/extensions/permessage_deflate/enabled.hpp>
struct deflate_client_config : public websocketpp::config::asio_client {
// ... additional custom config if you need it for other things
/// permessage_compress extension
struct permessage_deflate_config {};
typedef websocketpp::extensions::permessage_deflate::enabled
<permessage_deflate_config> permessage_deflate_type;
};
typedef websocketpp::client<deflate_client_config> client_endpoint_type;
```
## Security
### Is it possible to terminate a malicious connection quickly, without tying up resources performing clean close steps,
Yes. The library will automatically detect and terminate connections that violate the WebSocket protocol. In cases where the library believes the remote endpoint to be malicious or sufficiently broken to be unlikely to understand or process the closing handshake, it will be omited.
If your application detects conditions above the protocol level that you believe to be malicious, for example, if you recognize an IP from a known denial of service attack, you can close the connection with two different levels of urgency. Use the standard `websocketpp::endpoint::close` or `websocketpp::connection::close` methods with one of the following special close codes:
- `websocketpp::close::status::omit_handshake`: Omits the closing handshake, but cleanly closes the TCP connection.
- `websocketpp::close::status::force_tcp_drop`: Forcibly drop the TCP connection.
Please note that usage of these disconnect methods results in a violation of the WebSocket protocol and may have negative reprocusions for the remote endpoint with respect to network timeouts. Please use caution when using them.
## Build Issues
### Getting compile errors related to `std::chrono`, `boost::chrono`, `waitable_timer`, or `steady_clock`
Your build system may be confused about whether it is supposed to be using `boost::chrono` or `std::chrono`. Boost automatically detects this setup on some compilers but not others. Defining `BOOST_ASIO_HAS_STD_CHRONO` can help. See http://www.boost.org/doc/libs/1_60_0/doc/html/boost_asio/overview/cpp2011/chrono.html for more details.

/** \page reference.handlers Handler Reference
Handlers allow WebSocket++ programs to receive notifications about events
that happen in relation to their connections. Some handlers also behave as
hooks that give the program a chance to modify state or adjust settings before
the connection continues.
Handlers are registered by calling the appropriate `set_*_handler` method on either an
endpoint or connection. The * refers to the name of the handler (as
specified in the signature field below). For example, to set the open handler,
call `set_open_handler(...)`.
Setting handlers on an endpoint will result in them being copied as the default
handler to all new connections created by that endpoint. Changing an endpoint's
handlers will not affect connections that are already in progress. This includes
connections that are in the listening state. As such, it is important to set any
endpoint handlers before you call `endpoint::start_accept` or else the handlers
will not be attached to your first connection.
Setting handlers on a connection will result in the handler being changed for
that connection only, starting at the next time that handler is called. This can
be used to change the handler during a connection.
Connection Handlers
-------------------
These handlers will be called at most once per connection in the order specified below.
### Socket Init Handler
| Event | Signature | Availability |
| --------------------- | ----------------------------------------------------- | -------------------- |
| Socket initialization | `socket_init(connection_hdl, asio::ip::tcp::socket&)` | 0.3.0 Asio Transport |
This hook is triggered after the socket has been initialized but before a connection is established.
It allows setting arbitrary socket options before connections are sent/recieved.
### TCP Pre-init Handler
| Event | Signature | Availability |
| ----------------------------- | ------------------------------ | -------------------- |
| TCP established, no data sent | `tcp_pre_init(connection_hdl)` | 0.3.0 Asio Transport |
This hook is triggered after the TCP connection is established, but before any pre-WebSocket-handshake
operations have been run. Common pre-handshake operations include TLS handshakes and proxy connections.
### TCP Post-init Handler
| Event | Signature | Availability |
| ----------------------- | ------------------------------------------ | ----------------------------- |
| Request for TLS context | `tls_context_ptr tls_init(connection_hdl)` | 0.3.0 Asio Transport with TLS |
This hook is triggered before the TLS handshake to request the TLS context to use. You must
return a pointer to a configured TLS conext to continue. This provides the opportuinity to
set up the TLS settings, certificates, etc.
### Validate Handler
| Event | Signature | Availability |
| ------------------------------------- | ------------------------------- | ---------------------------- |
| Hook to accept or reject a connection | `bool validate(connection_hdl)` | 0.3.0 Core, Server role only |
This hook is triggered for servers during the opening handshake after the request has been
processed but before the response has been sent. It gives a program the opportunity to inspect
headers and other connection details and either accept or reject the connection. Validate happens
before the open or fail handler.
Return true to accept the connection, false to reject. If no validate handler is registered,
all connections will be accepted.
### Open Connection Handler
| Event | Signature | Availability |
| ------------------------- | ---------------------- | ------------ |
| Successful new connection | `open(connection_hdl)` | 0.3.0 Core |
Either open or fail will be called for each connection. Never both. All
connections that begin with an open handler call will also have a matching
close handler call when the connection ends.
### Fail Connection Handler
| Event | Signature | Availability |
| ----------------------------------- | ---------------------- | ------------ |
| Connection failed (before opening) | `fail(connection_hdl)` | 0.3.0 Core |
Either open or fail will be called for each connection. Never both. Connections
that fail will never have a close handler called.
### Close Connection Handler
| Event | Signature | Availability |
| --------------------------------- | ----------------------- | ------------ |
| Connection closed (after opening) | `close(connection_hdl)` | 0.3.0 Core |
Close will be called exactly once for every connection that open was called for.
Close is not called for failed connections.
Message Handlers
----------------
These handers are called in response to incoming messages or message like events. They only will be called while the connection is in the open state.
### Message Handler
| Event | Signature | Availability |
| --------------------- | -------------------------------------- | ------------ |
| Data message recieved | `message(connection_hdl, message_ptr)` | 0.3.0 Core |
Applies to all non-control messages, including both text and binary opcodes. The
`message_ptr` type and its API depends on your endpoint type and its config.
### Ping Handler
| Event | Signature | Availability |
| ------------- | ---------------------------------------- | ------------ |
| Ping recieved | `bool ping(connection_hdl, std::string)` | 0.3.0 Core |
Second (string) argument is the binary ping payload. Handler return value
indicates whether or not to respond to the ping with a pong. If no ping handler
is set, WebSocket++ will respond with a pong containing the same binary data as
the ping (Per requirements in RFC6455).
### Pong Handler
| Event | Signature | Availability |
| ------------- | ----------------------------------- | ------------ |
| Pong recieved | `pong(connection_hdl, std::string)` | 0.3.0 Core |
Second (string) argument is the binary pong payload.
### Pong Timeout Handler
| Event | Signature | Availability |
| ---------------------------------- | ------------------------------------------- | ---------------------------------------- |
| Timed out while waiting for a pong | `pong_timeout(connection_hdl, std::string)` | 0.3.0 Core, transport with timer support |
Triggered if there is no response to a ping after the configured duration. The second
(string) argument is the binary payload of the unanswered ping.
### HTTP Handler
| Event | Signature | Availability |
| --------------------- | --------------------- | ---------------------------- |
| HTTP request recieved | `http(connection_hdl` | 0.3.0 Core, Server role only |
Called when HTTP requests that are not WebSocket handshake upgrade requests are
recieved. Allows responding to regular HTTP requests. If no handler is registered
a 426/Upgrade Required error is returned.
### Interrupt Handler
| Event | Signature | Availability |
| ----------------------------------- | --------------------------- | ------------ |
| Connection was manually interrupted | `interrupt(connection_hdl)` | 0.3.0 Core |
Interrupt events can be triggered by calling `endpoint::interrupt` or `connection::interrupt`.
Interrupt is similar to a timer event with duration zero but with lower overhead. It is useful
for single threaded programs to allow breaking up a very long handler into multiple parts and
for multi threaded programs as a way for worker threads to signale to the main/network thread
that an event is ready.
todo: write low and high watermark handlers

/** \page reference.logging Logging Reference
WebSocket++ has the capability of logging events during the lifetime of the connections that it processes. Each endpoint has two independent logging interfaces that are used by all connections created by that endpoint. The first is an access interface that allows logging routine events in the life of a connection (such as connect/disconnect and receipt of messages). The other is an error interface that allows logging non-routine problems or errors. Each interface has a number of different named channels that can be toggled on and off independently.
Exactly how these logs are processed and where they are written to depends on which logging policy is in use. Several logging policies are included by default and you can write your own policy if you need something more specialized. Selecting a policy is done via the \subpage reference.config "endpoint config".
Common functionality (all policies)
-----------------------------------
### Logging Channels
Each logging interface is divided into 32 named channels. Log messages are written to a specific interface on a specific channel. Which log messages are actually printed is determined by which channels are enabled or not. Channels can be enabled or disabled either at compile time or at runtime.
### Enabling and Disabling Channels
Channels disabled at compile time are removed from the code entirely (assuming correct compiler optimization settings) and are not available for runtime enabling or disabling. To disable channels at compile time, use the `alog_level` and `elog_level` values within your \subpage reference.config "endpoint config". Channels not disabled at compile time can be enabled or disabled at runtime using the `websocketpp::endpoint::set_access_channels()`, `websocketpp::endpoint::clear_access_channels()`, `websocketpp::endpoint::set_error_channels()`, and `websocketpp::endpoint::clear_error_channels()` methods.
The set and clear functions act only on the channels specified. `set_access_channels(log::alevel::connect)` will enable logging of new connections. Following this with `set_access_channels(log::alevel::disconnect)` will enable logging of disconnections in addition to connections. Use `clear*` functions to disable a specific channel. Channels may be combined using bitwise operations to create aggregate packages of channels that may be set or cleared at once. Default packages include `websocketpp::log::alevel::all`, `websocketpp::log::elevel::all`, `websocketpp::log::alevel::none`, `websocketpp::log::elevel::none`. These represent all possible access/error channels and no access/error channels respectively. For convenience, setting none is aliased to clearing all.
### Examples
__Disable all__
`clear_access_channels(log::alevel::all)`
__Disable all (alternative method)__
`set_access_channels(log::alevel::none)`
__Multiple channels at once__
`log::alevel::message_payload | log::alevel::message_payload`
__All except one__
`log::alevel::all ^ log::alevel::message_payload`
__Default settings__
By default, only debug/development logging is disabled.
### Access to underlying loggers
Logging interfaces may be directly accessed via their associated endpoint or connection using get_alog() and get_elog(). This allows access to methods specific to the chosen logging policy.
Basic Logging (Default Policy)
------------------------------
The basic logging policy (`websocketpp::log::basic`) writes logs to a std::ostream. By default, access logs are written to stdout and error logs are written to stderr. Each logging interface may be optionally redirected to an arbitrary C++ stream (including file streams) using the `websocketpp::log::basic::set_ostream()` method.
Syslog Logging
--------------
The syslog logging policy (`websocketpp::log::syslog`) logs to POSIX syslog. It is included in the header `<websocketpp/logger/syslog.hpp>`. It requires a system with `<syslog.h>`.
Stub Logging
------------
The stub logging policy (`websocketpp::log::stub`) implements the logging policy interface but ignores all input and provides no output. It can be used to stub out the logging system in tests or to completely disable and remove nearly all logging related code.
The stub logger also provides documentation for the minimal required interface to build a custom logging policy.
Log level reference
-------------------
### Error Logging Levels
Each of these channels is in the namespace `websocketpp::log::elevel`
| Level | Description |
| ------- | -------------------------------------------------------------------------------------------------------------------------- |
| none | Special aggregate value representing "no levels" |
| devel | Low level debugging information (warning: very chatty). Requires debug or custom config. |
| library | Information about unusual system states or other minor internal library problems, less chatty than devel. |
| info | Information about minor configuration problems or additional information about other warnings. |
| warn | Information about important problems not severe enough to terminate connections. |
| rerror | Recoverable error. Recovery may mean cleanly closing the connection with an appropriate error code to the remote endpoint. |
| fatal | Unrecoverable error. This error will trigger immediate unclean termination of the connection or endpoint. |
| all | Special aggregate value representing "all levels" |
### Access Logging Levels
Each of these channels is in the namespace `websocketpp::log::alevel`
| Level | Description |
| --------------- | -------------------------------------------------------------------------------------------------- |
| none | Special aggregate value representing "no levels" |
| connect | One line for each new connection that includes a host of information including: the remote address, websocket version, requested resource, http code, remote user agent |
| disconnect | One line for each connection that is closed. Includes closing codes and reasons |
| control | One line per control message |
| frame_header | One line per frame, includes the full frame header |
| frame_payload | One line per frame, includes the full message payload (warning: lots of output for large messages) |
| message_header | Reserved |
| message_payload | Reserved |
| endpoint | Reserved |
| debug_handshake | Extra information about opening handshakes |
| debug_close | Extra information about closing handshakes |
| devel | Development messages (warning: very chatty). Requires debug or custom config. |
| app | Special channel for application specific logs. Not used by the library. |
| all | Special aggregate value representing "all levels" |

/** \mainpage
WebSocket++ is a C++ library that can be used to implement WebSocket functionality. The goals of the project are to provide a WebSocket implementation that is portable, flexible, lightweight, low level, and high performance.
WebSocket++ does not intend to be used alone as a web application framework or full featured web services platform. As such the components, examples, and performance tuning are geared towards operation as a WebSocket client or server. There are some minimal convenience features that stray from this (for example the ability to respond to HTTP requests other than WebSocket Upgrades) but these are not the focus of the project. In particular WebSocket++ does not intend to implement any non-WebSocket related fallback options (ajax / long polling / comet / etc).
In order to remain compact and improve portability, the WebSocket++ project strives to reduce or eliminate external dependencies where possible and appropriate. WebSocket++ core has no dependencies other than the C++11 standard library. For non-C++11 compilers the Boost libraries provide drop in polyfills for the C++11 functionality used.
WebSocket++ implements a pluggable data transport component. The default component allows reduced functionality by using STL iostream or raw byte shuffling via reading and writing char buffers. This component has no non-STL dependencies and can be used in a C++11 environment without Boost. Also included is an Asio based transport component that provides full featured network client/server functionality. This component requires either Boost Asio or a C++11 compiler and standalone Asio. As an advanced option, WebSocket++ supports custom transport layers if you want to provide your own using another library.
In order to accommodate the wide variety of use cases WebSocket++ has collected, the library is built in a way that most of the major components are loosely coupled and can be swapped out and replaced. WebSocket++ will attempt to track the future development of the WebSocket protocol and any extensions as they are developed.

* case of connect and actually perform basic verification of server certs this
* example includes a basic implementation (using Asio and OpenSSL) of the
* following reasonable default settings and verification steps:
*
* - Disable SSLv2 and SSLv3
* - Load trusted CA certificates and verify the server cert is trusted.
* - Verify that the hostname matches either the common name or one of the
* subject alternative names on the certificate.
*
* This is not meant to be an exhaustive reference implimentation of a perfect
* TLS client, but rather a reasonable starting point for building a secure
* TLS encrypted WebSocket client.
*
* If any TLS, Asio, or OpenSSL experts feel that these settings are poor
* defaults or there are critically missing steps please open a GitHub issue
* or drop a line on the project mailing list.
*
* Note the bundled CA cert ca-chain.cert.pem is the CA cert that signed the
* cert bundled with echo_server_tls. You can use print_client_tls with this
* CA cert to connect to echo_server_tls as long as you use /etc/hosts or
* something equivilent to spoof one of the names on that cert

Checkout the project from git
At the top level, run cmake:
cmake -G 'Unix Makefiles' \
-D BUILD_EXAMPLES=ON \
-D WEBSOCKETPP_ROOT=/tmp/cm1 \
-D ENABLE_CPP11=OFF .
and then make the example:
make -C examples/sip_client
Now run it:
bin/sip_client ws://ws-server:80
It has been tested against the repro SIP proxy from reSIProcate

* The telemetry server accepts connections and sends a message every second to

*
* This example uses the timer based concurrency method and is self contained
* and singled threaded. Refer to telemetry client for an example of a similar
* telemetry setup using threads rather than timers.
*
* This example also includes an example simple HTTP server that serves a web
* dashboard displaying the count. This simple design is suitable for use
* delivering a small number of files to a small number of clients. It is ideal
* for cases like embedded dashboards that don't want the complexity of an extra
* HTTP server to serve static files.
*
* This design *will* fall over under high traffic or DoS conditions. In such

WebSocket++ (0.8.2)
==========================
WebSocket++ is a header only C++ library that implements RFC6455 The WebSocket
Protocol. It allows integrating WebSocket client and server functionality into
C++ programs. It uses interchangeable network transport modules including one
based on raw char buffers, one based on C++ iostreams, and one based on Asio
(either via Boost or standalone). End users can write additional transport
policies to support other networking or event libraries as needed.
Major Features
==============
* Full support for RFC6455
* Partial support for Hixie 76 / Hybi 00, 07-17 draft specs (server only)
* Message/event based interface
* Supports secure WebSockets (TLS), IPv6, and explicit proxies.
* Flexible dependency management (C++11 Standard Library or Boost)
* Interchangeable network transport modules (raw, iostream, Asio, or custom)
* Portable/cross platform (Posix/Windows, 32/64bit, Intel/ARM/PPC)
* Thread-safe
