TUN-7227: Migrate to devincarr/quic-go 

The lucas-clemente/quic-go package moved namespaces and our branch
went stale, this new fork provides support for the new quic-go repo
and applies the max datagram frame size change.

Until the max datagram frame size support gets upstreamed into quic-go,
this can be used to unblock go 1.20 support as the old
lucas-clemente/quic-go will not get go 1.20 support.

# genny - Generics for Go
[![Build Status](https://travis-ci.org/cheekybits/genny.svg?branch=master)](https://travis-ci.org/cheekybits/genny) [![GoDoc](https://godoc.org/github.com/cheekybits/genny/parse?status.png)](http://godoc.org/github.com/cheekybits/genny/parse)
Install:
```
go get github.com/cheekybits/genny
```
=====
(pron. Jenny) by Mat Ryer ([@matryer](https://twitter.com/matryer)) and Tyler Bunnell ([@TylerJBunnell](https://twitter.com/TylerJBunnell)).
Until the Go core team include support for [generics in Go](http://golang.org/doc/faq#generics), `genny` is a code-generation generics solution. It allows you write normal buildable and testable Go code which, when processed by the `genny gen` tool, will replace the generics with specific types.
* Generic code is valid Go code
* Generic code compiles and can be tested
* Use `stdin` and `stdout` or specify in and out files
* Supports Go 1.4's [go generate](http://tip.golang.org/doc/go1.4#gogenerate)
* Multiple specific types will generate every permutation
* Use `BUILTINS` and `NUMBERS` wildtype to generate specific code for all built-in (and number) Go types
* Function names and comments also get updated
## Library
We have started building a [library of common things](https://github.com/cheekybits/gennylib), and you can use `genny get` to generate the specific versions you need.
For example: `genny get maps/concurrentmap.go "KeyType=BUILTINS ValueType=BUILTINS"` will print out generated code for all types for a concurrent map. Any file in the library may be generated locally in this way using all the same options given to `genny gen`.
## Usage
```
genny [{flags}] gen "{types}"
gen - generates type specific code from generic code.
get <package/file> - fetch a generic template from the online library and gen it.
{flags} - (optional) Command line flags (see below)
{types} - (required) Specific types for each generic type in the source
{types} format: {generic}={specific}[,another][ {generic2}={specific2}]
Examples:
Generic=Specific
Generic1=Specific1 Generic2=Specific2
Generic1=Specific1,Specific2 Generic2=Specific3,Specific4
Flags:
-in="": file to parse instead of stdin
-out="": file to save output to instead of stdout
-pkg="": package name for generated files
```
* Comma separated type lists will generate code for each type
### Flags
* `-in` - specify the input file (rather than using stdin)
* `-out` - specify the output file (rather than using stdout)
### go generate
To use Go 1.4's `go generate` capability, insert the following comment in your source code file:
```
//go:generate genny -in=$GOFILE -out=gen-$GOFILE gen "KeyType=string,int ValueType=string,int"
```
* Start the line with `//go:generate `
* Use the `-in` and `-out` flags to specify the files to work on
* Use the `genny` command as usual after the flags
Now, running `go generate` (in a shell) for the package will cause the generic versions of the files to be generated.
* The output file will be overwritten, so it's safe to call `go generate` many times
* Use `$GOFILE` to refer to the current file
* The `//go:generate` line will be removed from the output
To see a real example of how to use `genny` with `go generate`, look in the [example/go-generate directory](https://github.com/cheekybits/genny/tree/master/examples/go-generate).
## How it works
Define your generic types using the special `generic.Type` placeholder type:
```go
type KeyType generic.Type
type ValueType generic.Type
```
* You can use as many as you like
* Give them meaningful names
Then write the generic code referencing the types as your normally would:
```go
func SetValueTypeForKeyType(key KeyType, value ValueType) { /* ... */ }
```
* Generic type names will also be replaced in comments and function names (see Real example below)
Since `generic.Type` is a real Go type, your code will compile, and you can even write unit tests against your generic code.
#### Generating specific versions
Pass the file through the `genny gen` tool with the specific types as the argument:
```
cat generic.go | genny gen "KeyType=string ValueType=interface{}"
```
The output will be the complete Go source file with the generic types replaced with the types specified in the arguments.
## Real example
Given [this generic Go code](https://github.com/cheekybits/genny/tree/master/examples/queue) which compiles and is tested:
```go
package queue
import "github.com/cheekybits/genny/generic"
// NOTE: this is how easy it is to define a generic type
type Something generic.Type
// SomethingQueue is a queue of Somethings.
type SomethingQueue struct {
items []Something
}
func NewSomethingQueue() *SomethingQueue {
return &SomethingQueue{items: make([]Something, 0)}
}
func (q *SomethingQueue) Push(item Something) {
q.items = append(q.items, item)
}
func (q *SomethingQueue) Pop() Something {
item := q.items[0]
q.items = q.items[1:]
return item
}
```
When `genny gen` is invoked like this:
```
cat source.go | genny gen "Something=string"
```
It outputs:
```go
// This file was automatically generated by genny.
// Any changes will be lost if this file is regenerated.
// see https://github.com/cheekybits/genny
package queue
// StringQueue is a queue of Strings.
type StringQueue struct {
items []string
}
func NewStringQueue() *StringQueue {
return &StringQueue{items: make([]string, 0)}
}
func (q *StringQueue) Push(item string) {
q.items = append(q.items, item)
}
func (q *StringQueue) Pop() string {
item := q.items[0]
q.items = q.items[1:]
return item
}
```
To get a _something_ for every built-in Go type plus one of your own types, you could run:
```
cat source.go | genny gen "Something=BUILTINS,*MyType"
```
#### More examples
Check out the [test code files](https://github.com/cheekybits/genny/tree/master/parse/test) for more real examples.
## Writing test code
Once you have defined a generic type with some code worth testing:
```go
package slice
import (
"log"
"reflect"
"github.com/stretchr/gogen/generic"
)
type MyType generic.Type
func EnsureMyTypeSlice(objectOrSlice interface{}) []MyType {
log.Printf("%v", reflect.TypeOf(objectOrSlice))
switch obj := objectOrSlice.(type) {
case []MyType:
log.Println(" returning it untouched")
return obj
case MyType:
log.Println(" wrapping in slice")
return []MyType{obj}
default:
panic("ensure slice needs MyType or []MyType")
}
}
```
You can treat it like any normal Go type in your test code:
```go
func TestEnsureMyTypeSlice(t *testing.T) {
myType := new(MyType)
slice := EnsureMyTypeSlice(myType)
if assert.NotNil(t, slice) {
assert.Equal(t, slice[0], myType)
}
slice = EnsureMyTypeSlice(slice)
log.Printf("%#v", slice[0])
if assert.NotNil(t, slice) {
assert.Equal(t, slice[0], myType)
}
}
```
### Understanding what `generic.Type` is
Because `generic.Type` is an empty interface type (literally `interface{}`) every other type will be considered to be a `generic.Type` if you are switching on the type of an object. Of course, once the specific versions are generated, this issue goes away but it's worth knowing when you are writing your tests against generic code.

(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

// This file is a simple protocol buffer encoder and decoder.

// A protocol message must implement the message interface:

# A QUIC implementation in pure Go

[![PkgGoDev](https://pkg.go.dev/badge/github.com/lucas-clemente/quic-go)](https://pkg.go.dev/github.com/lucas-clemente/quic-go)
[![Code Coverage](https://img.shields.io/codecov/c/github/lucas-clemente/quic-go/master.svg?style=flat-square)](https://codecov.io/gh/lucas-clemente/quic-go/)
quic-go is an implementation of the QUIC protocol ([RFC 9000](https://datatracker.ietf.org/doc/html/rfc9000), [RFC 9001](https://datatracker.ietf.org/doc/html/rfc9001), [RFC 9002](https://datatracker.ietf.org/doc/html/rfc9002)) in Go, including the [Unreliable Datagram Extension, RFC 9221](https://datatracker.ietf.org/doc/html/rfc9221). It has support for HTTP/3 [RFC 9114](https://datatracker.ietf.org/doc/html/rfc9114).
In addition the RFCs listed above, it currently implements the [IETF QUIC draft-29](https://tools.ietf.org/html/draft-ietf-quic-transport-29). Support for draft-29 will eventually be dropped, as it is phased out of the ecosystem.

### QUIC without HTTP/3
Take a look at [this echo example](example/echo/echo.go).
## Usage
### As a server
See the [example server](example/main.go). Starting a QUIC server is very similar to the standard lib http in go:
```go
http.Handle("/", http.FileServer(http.Dir(wwwDir)))
http3.ListenAndServeQUIC("localhost:4242", "/path/to/cert/chain.pem", "/path/to/privkey.pem", nil)
```
### As a client
See the [example client](example/client/main.go). Use a `http3.RoundTripper` as a `Transport` in a `http.Client`.
```go
http.Client{
Transport: &http3.RoundTripper{},
}
```
