"Contribution" means:
Copyright (c) 2007, Eclipse Foundation, Inc. and its licensors.
a) in the case of the initial Contributor, the initial code and documentation distributed under this Agreement, and
All rights reserved.
b) in the case of each subsequent Contributor:
Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met:
i) changes to the Program, and
Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer.

IN NO EVENT SHALL THE COPYRIGHT OWNER OR CONTRIBUTORS BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO, PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.
where such changes and/or additions to the Program originate from and are distributed by that particular Contributor. A Contribution 'originates' from a Contributor if it was added to the Program by such Contributor itself or anyone acting on such Contributor's behalf. Contributions do not include additions to the Program which: (i) are separate modules of software distributed in conjunction with the Program under their own license agreement, and (ii) are not derivative works of the Program.
"Contributor" means any person or entity that distributes the Program.
"Licensed Patents" mean patent claims licensable by a Contributor which are necessarily infringed by the use or sale of its Contribution alone or when combined with the Program.
"Program" means the Contributions distributed in accordance with this Agreement.
"Recipient" means anyone who receives the Program under this Agreement, including all Contributors.
2. GRANT OF RIGHTS
a) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code form.
b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder.
c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise. As a condition to exercising the rights and licenses granted hereunder, each Recipient hereby assumes sole responsibility to secure any other intellectual property rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program.
d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to grant the copyright license set forth in this Agreement.
3. REQUIREMENTS
A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that:
a) it complies with the terms and conditions of this Agreement; and
b) its license agreement:
i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and fitness for a particular purpose;
ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, incidental and consequential damages, such as lost profits;
iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any other party; and
iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange.
When the Program is made available in source code form:
a) it must be made available under this Agreement; and
b) a copy of this Agreement must be included with each copy of the Program.
Contributors may not remove or alter any copyright notices contained within the Program.
Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows subsequent Recipients to identify the originator of the Contribution.
4. COMMERCIAL DISTRIBUTION
Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes the Program in a commercial product offering should do so in a manner which does not create potential liability for other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor ("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may participate in any such claim at its own expense.
For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, the Commercial Contributor must pay those damages.
5. NO WARRANTY
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the appropriateness of using and distributing the Program and assumes all risks associated with its exercise of rights under this Agreement , including but not limited to the risks and costs of program errors, compliance with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations.
6. DISCLAIMER OF LIABILITY
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
7. GENERAL
If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.
If Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such litigation is filed.
All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses granted by Recipient relating to the Program shall continue and survive.
Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the right to modify this Agreement. The Eclipse Foundation is the initial Agreement Steward. The Eclipse Foundation may assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.
This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause of action arose. Each party waives its rights to a jury trial in any resulting litigation.

Eclipse Paho MQTT Go client
===========================
This repository contains the source code for the [Eclipse Paho](http://eclipse.org/paho) MQTT Go client library.
This repository contains the source code for the [Eclipse Paho](https://eclipse.org/paho) MQTT 3.1/3.11 Go client library.
This code builds a library which enable applications to connect to an [MQTT](http://mqtt.org) broker to publish messages, and to subscribe to topics and receive published messages.
This code builds a library which enable applications to connect to an [MQTT](https://mqtt.org) broker to publish
messages, and to subscribe to topics and receive published messages.
This library supports a fully asynchronous mode of operation.
A client supporting MQTT V5 is [also available](https://github.com/eclipse/paho.golang).
Installation and Build
----------------------
This client is designed to work with the standard Go tools, so installation is as easy as:
The process depends upon whether you are using [modules](https://golang.org/ref/mod) (recommended) or `GOPATH`.
#### Modules
If you are using [modules](https://blog.golang.org/using-go-modules) then `import "github.com/eclipse/paho.mqtt.golang"`
and start using it. The necessary packages will be download automatically when you run `go build`.
Note that the latest release will be downloaded and changes may have been made since the release. If you have
encountered an issue, or wish to try the latest code for another reason, then run
`go get github.com/eclipse/paho.mqtt.golang@master` to get the latest commit.
#### GOPATH
Installation is as easy as:
```
go get github.com/eclipse/paho.mqtt.golang
```
The client depends on Google's [websockets](https://godoc.org/golang.org/x/net/websocket) and [proxy](https://godoc.org/golang.org/x/net/proxy) package,
also easily installed with the commands:

@ -35,27 +50,115 @@ Usage and API
-------------
Detailed API documentation is available by using to godoc tool, or can be browsed online
using the [godoc.org](http://godoc.org/github.com/eclipse/paho.mqtt.golang) service.
Make use of the library by importing it in your Go client source code. For example,
```
import "github.com/eclipse/paho.mqtt.golang"
```
using the [pkg.go.dev](https://pkg.go.dev/github.com/eclipse/paho.mqtt.golang) service.
Samples are available in the `cmd` directory for reference.
Note:
Runtime tracing
The library also supports using MQTT over websockets by using the `ws://` (unsecure) or `wss://` (secure) prefix in the
URI. If the client is running behind a corporate http/https proxy then the following environment variables `HTTP_PROXY`,
`HTTPS_PROXY` and `NO_PROXY` are taken into account when establishing the connection.
Troubleshooting
---------------
Tracing is enabled by assigning logs (from the Go log package) to the logging endpoints, ERROR, CRITICAL, WARN and DEBUG
If you are new to MQTT and your application is not working as expected reviewing the
[MQTT specification](https://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html), which this library implements,
is a good first step. [MQTT.org](https://mqtt.org) has some [good resources](https://mqtt.org/getting-started/) that answer many
common questions.
### Error Handling
The asynchronous nature of this library makes it easy to forget to check for errors. Consider using a go routine to
log these:
```go
t := client.Publish("topic", qos, retained, msg)
go func() {
_ = t.Wait() // Can also use '<-t.Done()' in releases > 1.2.0
if t.Error() != nil {
log.Error(t.Error()) // Use your preferred logging technique (or just fmt.Printf)
}
}()
```
### Logging
If you are encountering issues then enabling logging, both within this library and on your broker, is a good way to
begin troubleshooting. This library can produce various levels of log by assigning the logging endpoints, ERROR,
CRITICAL, WARN and DEBUG. For example:
```go
func main() {
mqtt.ERROR = log.New(os.Stdout, "[ERROR] ", 0)
mqtt.CRITICAL = log.New(os.Stdout, "[CRIT] ", 0)
mqtt.WARN = log.New(os.Stdout, "[WARN] ", 0)
mqtt.DEBUG = log.New(os.Stdout, "[DEBUG] ", 0)
// Connect, Subscribe, Publish etc..
}
```
### Common Problems
* Seemingly random disconnections may be caused by another client connecting to the broker with the same client
identifier; this is as per the [spec](https://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html#_Toc384800405).
* A `MessageHandler` (called when a new message is received) must not block. If you wish to perform a long-running task,
or publish a message, then please use a go routine (blocking in the handler is a common cause of unexpected `pingresp
not received, disconnecting` errors).
* When QOS1+ subscriptions have been created previously and you connect with `CleanSession` set to false it is possible that the broker will deliver retained
messages before `Subscribe` can be called. To process these messages either configure a handler with `AddRoute` or
set a `DefaultPublishHandler`.
* Loss of network connectivity may not be detected immediately. If this is an issue then consider setting
`ClientOptions.KeepAlive` (sends regular messages to check the link is active).
* Brokers offer many configuration options; some settings may lead to unexpected results. If using Mosquitto check
`max_inflight_messages`, `max_queued_messages`, `persistence` (the defaults may not be what you expect).
Reporting bugs
--------------
Please report bugs by raising issues for this project in github https://github.com/eclipse/paho.mqtt.golang/issues
*A limited number of contributors monitor the issues section so if you have a general question please consider the
resources in the [more information](#more-information) section (your question will be seen by more people, and you are
likely to receive an answer more quickly).*
We welcome bug reports, but it is important they are actionable. A significant percentage of issues reported are not
resolved due to a lack of information. If we cannot replicate the problem then it is unlikely we will be able to fix it.
The information required will vary from issue to issue but consider including:
* Which version of the package you are using (tag or commit - this should be in your go.mod file)
* A [Minimal, Reproducible Example](https://stackoverflow.com/help/minimal-reproducible-example). Providing an example
is the best way to demonstrate the issue you are facing; it is important this includes all relevant information
(including broker configuration). Docker (see `cmd/docker`) makes it relatively simple to provide a working end-to-end
example.
* A full, clear, description of the problem (detail what you are expecting vs what actually happens).
* Details of your attempts to resolve the issue (what have you tried, what worked, what did not).
* [Application Logs](#logging) covering the period the issue occurred. Unless you have isolated the root cause of the issue please include a link to a full log (including data from well before the problem arose).
* Broker Logs covering the period the issue occurred.
It is important to remember that this library does not stand alone; it communicates with a broker and any issues you are
seeing may be due to:
* Bugs in your code.
* Bugs in this library.
* The broker configuration.
* Bugs in the broker.
* Issues with whatever you are communicating with.
When submitting an issue, please ensure that you provide sufficient details to enable us to eliminate causes outside of
this library.
Contributing
------------
We welcome pull requests but before your contribution can be accepted by the project, you need to create and
electronically sign the Eclipse Contributor Agreement (ECA) and sign off on the Eclipse Foundation Certificate of Origin.
More information is available in the
[Eclipse Development Resources](http://wiki.eclipse.org/Development_Resources/Contributing_via_Git); please take special
note of the requirement that the commit record contain a "Signed-off-by" entry.

# Gorilla WebSocket
[![GoDoc](https://godoc.org/github.com/gorilla/websocket?status.svg)](https://godoc.org/github.com/gorilla/websocket)
[![CircleCI](https://circleci.com/gh/gorilla/websocket.svg?style=svg)](https://circleci.com/gh/gorilla/websocket)
Gorilla WebSocket is a [Go](http://golang.org/) implementation of the
[WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol.
### Documentation
* [API Reference](https://pkg.go.dev/github.com/gorilla/websocket?tab=doc)
* [Chat example](https://github.com/gorilla/websocket/tree/master/examples/chat)
* [Command example](https://github.com/gorilla/websocket/tree/master/examples/command)
* [Client and server example](https://github.com/gorilla/websocket/tree/master/examples/echo)
* [File watch example](https://github.com/gorilla/websocket/tree/master/examples/filewatch)
### Status
The Gorilla WebSocket package provides a complete and tested implementation of
the [WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol. The
package API is stable.
### Installation
go get github.com/gorilla/websocket
### Protocol Compliance
The Gorilla WebSocket package passes the server tests in the [Autobahn Test
Suite](https://github.com/crossbario/autobahn-testsuite) using the application in the [examples/autobahn
subdirectory](https://github.com/gorilla/websocket/tree/master/examples/autobahn).

Notes:
1. Large messages are fragmented in [Chrome's new WebSocket implementation](http://www.ietf.org/mail-archive/web/hybi/current/msg10503.html).
2. The application can get the type of a received data message by implementing
a [Codec marshal](http://godoc.org/golang.org/x/net/websocket#Codec.Marshal)
function.
3. The go.net io.Reader and io.Writer operate across WebSocket frame boundaries.
Read returns when the input buffer is full or a frame boundary is
encountered. Each call to Write sends a single frame message. The Gorilla
io.Reader and io.WriteCloser operate on a single WebSocket message.

// Package websocket implements the WebSocket protocol defined in RFC 6455.
//
// Overview
//
// The Conn type represents a WebSocket connection. A server application calls
// the Upgrader.Upgrade method from an HTTP request handler to get a *Conn:
//
// var upgrader = websocket.Upgrader{
// ReadBufferSize: 1024,
// WriteBufferSize: 1024,
// }
//
// func handler(w http.ResponseWriter, r *http.Request) {
// conn, err := upgrader.Upgrade(w, r, nil)
// if err != nil {
// log.Println(err)
// return
// }
// ... Use conn to send and receive messages.
// }
//
// Call the connection's WriteMessage and ReadMessage methods to send and
// receive messages as a slice of bytes. This snippet of code shows how to echo
// messages using these methods:
//
// for {
// messageType, p, err := conn.ReadMessage()
// if err != nil {
// log.Println(err)
// return
// }
// if err := conn.WriteMessage(messageType, p); err != nil {
// log.Println(err)
// return
// }
// }
//
// In above snippet of code, p is a []byte and messageType is an int with value
// websocket.BinaryMessage or websocket.TextMessage.
//
// An application can also send and receive messages using the io.WriteCloser
// and io.Reader interfaces. To send a message, call the connection NextWriter
// method to get an io.WriteCloser, write the message to the writer and close
// the writer when done. To receive a message, call the connection NextReader
// method to get an io.Reader and read until io.EOF is returned. This snippet
// shows how to echo messages using the NextWriter and NextReader methods:
//
// for {
// messageType, r, err := conn.NextReader()
// if err != nil {
// return
// }
// w, err := conn.NextWriter(messageType)
// if err != nil {
// return err
// }
// if _, err := io.Copy(w, r); err != nil {
// return err
// }
// if err := w.Close(); err != nil {
// return err
// }
// }
//
// Data Messages
//
// The WebSocket protocol distinguishes between text and binary data messages.
// Text messages are interpreted as UTF-8 encoded text. The interpretation of
// binary messages is left to the application.
//
// This package uses the TextMessage and BinaryMessage integer constants to
// identify the two data message types. The ReadMessage and NextReader methods
// return the type of the received message. The messageType argument to the
// WriteMessage and NextWriter methods specifies the type of a sent message.
//
// It is the application's responsibility to ensure that text messages are
// valid UTF-8 encoded text.
//
// Control Messages
//
// The WebSocket protocol defines three types of control messages: close, ping
// and pong. Call the connection WriteControl, WriteMessage or NextWriter
// methods to send a control message to the peer.
//
// Connections handle received close messages by calling the handler function
// set with the SetCloseHandler method and by returning a *CloseError from the
// NextReader, ReadMessage or the message Read method. The default close
// handler sends a close message to the peer.
//
// Connections handle received ping messages by calling the handler function
// set with the SetPingHandler method. The default ping handler sends a pong
// message to the peer.
//
// Connections handle received pong messages by calling the handler function
// set with the SetPongHandler method. The default pong handler does nothing.
// If an application sends ping messages, then the application should set a
// pong handler to receive the corresponding pong.
//
// The control message handler functions are called from the NextReader,
// ReadMessage and message reader Read methods. The default close and ping
// handlers can block these methods for a short time when the handler writes to
// the connection.
//
// The application must read the connection to process close, ping and pong
// messages sent from the peer. If the application is not otherwise interested
// in messages from the peer, then the application should start a goroutine to
// read and discard messages from the peer. A simple example is:
//
// func readLoop(c *websocket.Conn) {
// for {
// if _, _, err := c.NextReader(); err != nil {
// c.Close()
// break
// }
// }
// }
//
// Concurrency
//
// Connections support one concurrent reader and one concurrent writer.
//
// Applications are responsible for ensuring that no more than one goroutine
// calls the write methods (NextWriter, SetWriteDeadline, WriteMessage,
// WriteJSON, EnableWriteCompression, SetCompressionLevel) concurrently and
// that no more than one goroutine calls the read methods (NextReader,
// SetReadDeadline, ReadMessage, ReadJSON, SetPongHandler, SetPingHandler)
// concurrently.
//
// The Close and WriteControl methods can be called concurrently with all other
// methods.
//
// Origin Considerations
//
// Web browsers allow Javascript applications to open a WebSocket connection to
// any host. It's up to the server to enforce an origin policy using the Origin
// request header sent by the browser.
//
// The Upgrader calls the function specified in the CheckOrigin field to check
// the origin. If the CheckOrigin function returns false, then the Upgrade
// method fails the WebSocket handshake with HTTP status 403.
//
// If the CheckOrigin field is nil, then the Upgrader uses a safe default: fail
// the handshake if the Origin request header is present and the Origin host is
// not equal to the Host request header.
//
// The deprecated package-level Upgrade function does not perform origin
// checking. The application is responsible for checking the Origin header
// before calling the Upgrade function.
//
// Buffers
//
// Connections buffer network input and output to reduce the number
// of system calls when reading or writing messages.
//
// Write buffers are also used for constructing WebSocket frames. See RFC 6455,
// Section 5 for a discussion of message framing. A WebSocket frame header is
// written to the network each time a write buffer is flushed to the network.
// Decreasing the size of the write buffer can increase the amount of framing
// overhead on the connection.
//
// The buffer sizes in bytes are specified by the ReadBufferSize and
// WriteBufferSize fields in the Dialer and Upgrader. The Dialer uses a default
// size of 4096 when a buffer size field is set to zero. The Upgrader reuses
// buffers created by the HTTP server when a buffer size field is set to zero.
// The HTTP server buffers have a size of 4096 at the time of this writing.
//
// The buffer sizes do not limit the size of a message that can be read or
// written by a connection.
//
// Buffers are held for the lifetime of the connection by default. If the
// Dialer or Upgrader WriteBufferPool field is set, then a connection holds the
// write buffer only when writing a message.
//
// Applications should tune the buffer sizes to balance memory use and
// performance. Increasing the buffer size uses more memory, but can reduce the
// number of system calls to read or write the network. In the case of writing,
// increasing the buffer size can reduce the number of frame headers written to
// the network.
//
// Some guidelines for setting buffer parameters are:
//
// Limit the buffer sizes to the maximum expected message size. Buffers larger
// than the largest message do not provide any benefit.
//
// Depending on the distribution of message sizes, setting the buffer size to
// a value less than the maximum expected message size can greatly reduce memory
// use with a small impact on performance. Here's an example: If 99% of the
// messages are smaller than 256 bytes and the maximum message size is 512
// bytes, then a buffer size of 256 bytes will result in 1.01 more system calls
// than a buffer size of 512 bytes. The memory savings is 50%.
//
// A write buffer pool is useful when the application has a modest number
// writes over a large number of connections. when buffers are pooled, a larger
// buffer size has a reduced impact on total memory use and has the benefit of
// reducing system calls and frame overhead.
//
// Compression EXPERIMENTAL
//
// Per message compression extensions (RFC 7692) are experimentally supported
// by this package in a limited capacity. Setting the EnableCompression option
// to true in Dialer or Upgrader will attempt to negotiate per message deflate
// support.
//
// var upgrader = websocket.Upgrader{
// EnableCompression: true,
// }
//
// If compression was successfully negotiated with the connection's peer, any
// message received in compressed form will be automatically decompressed.
// All Read methods will return uncompressed bytes.
//
// Per message compression of messages written to a connection can be enabled
// or disabled by calling the corresponding Conn method:
//
// conn.EnableWriteCompression(false)
//
// Currently this package does not support compression with "context takeover".
// This means that messages must be compressed and decompressed in isolation,
// without retaining sliding window or dictionary state across messages. For
// more details refer to RFC 7692.
//
// Use of compression is experimental and may result in decreased performance.
