## 2023.2.2
### Notices
- Legacy tunnels were officially deprecated on December 1, 2022. Starting with this version, cloudflared no longer supports connecting legacy tunnels.
- h2mux tunnel connection protocol is no longer supported. Any tunnels still configured to use this protocol will alert and use http2 tunnel protocol instead. We recommend using quic protocol for all tunnels going forward.
## 2023.2.1
### Bug fixes
- Fixed a bug in TCP connection proxy that could result in the connection being closed before all data was written.
- cloudflared now correctly aborts body write if connection to origin service fails after response headers were sent already.
- Fixed a bug introduced in the previous release where debug endpoints were removed.
## 2022.12.0
### Improvements
- cloudflared now attempts to try other edge addresses before falling back to a lower protoocol.

## TOML parser and encoder for Go with reflection
TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
reflection interface similar to Go's standard library `json` and `xml`
packages. This package also supports the `encoding.TextUnmarshaler` and
`encoding.TextMarshaler` interfaces so that you can define custom data
representations. (There is an example of this below.)

Compatible with TOML version [v1.0.0](https://toml.io/en/v1.0.0).
Compatible with TOML version

Documentation: https://godocs.io/github.com/BurntSushi/toml
Documentation: https://godoc.org/github.com/BurntSushi/toml
See the [releases page](https://github.com/BurntSushi/toml/releases) for a
changelog; this information is also in the git tag annotations (e.g. `git show
v0.4.0`).
Installation:
This library requires Go 1.13 or newer; add it to your go.mod with:
```bash
go get github.com/BurntSushi/toml
```
% go get github.com/BurntSushi/toml@latest
Try the toml validator:
It also comes with a TOML validator CLI tool:
```bash
go get github.com/BurntSushi/toml/cmd/tomlv
tomlv some-toml-file.toml
```

### Testing
This package passes all tests in
[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
and the encoder.
% go install github.com/BurntSushi/toml/cmd/tomlv@latest
% tomlv some-toml-file.toml
### Examples
This package works similarly to how the Go standard library handles `XML`
and `JSON`. Namely, data is loaded into Go values via reflection.
For the simplest example, consider some TOML file as just a list of keys
and values:

### Using the `encoding.TextUnmarshaler` interface
Beware that like other decoders **only exported fields** are considered when
encoding and decoding; private fields are silently ignored.
Here's an example that automatically parses duration strings into
`time.Duration` values:
### Using the `Marshaler` and `encoding.TextUnmarshaler` interfaces
Here's an example that automatically parses values in a `mail.Address`:
```toml
[[song]]
name = "Thunder Road"
duration = "4m49s"
[[song]]
name = "Stairway to Heaven"
duration = "8m03s"
```
Which can be decoded with:
```go
type song struct {
Name string
Duration duration
}
type songs struct {
Song []song
}
var favorites songs
if _, err := toml.Decode(blob, &favorites); err != nil {
log.Fatal(err)
}
for _, s := range favorites.Song {
fmt.Printf("%s (%s)\n", s.Name, s.Duration)
}
```
And you'll also need a `duration` type that satisfies the
`encoding.TextUnmarshaler` interface:
```go
type duration struct {
time.Duration
}
func (d *duration) UnmarshalText(text []byte) error {
var err error
d.Duration, err = time.ParseDuration(string(text))
return err
}
```
### More complex usage
Here's an example of how to load the example from the official spec page:
```toml
# This is a TOML document. Boom.
title = "TOML Example"
[owner]
name = "Tom Preston-Werner"
organization = "GitHub"
bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
dob = 1979-05-27T07:32:00Z # First class dates? Why not?
[database]
server = "192.168.1.1"
ports = [ 8001, 8001, 8002 ]
connection_max = 5000
enabled = true
[servers]
# You can indent as you please. Tabs or spaces. TOML don't care.
[servers.alpha]
ip = "10.0.0.1"
dc = "eqdc10"
[servers.beta]
ip = "10.0.0.2"
dc = "eqdc10"
[clients]
data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
# Line breaks are OK when inside arrays
hosts = [
"alpha",
"omega"
contacts = [
"Donald Duck <donald@duckburg.com>",
"Scrooge McDuck <scrooge@duckburg.com>",
]
```
And the corresponding Go types are:
Can be decoded with:
```go
type tomlConfig struct {
Title string
Owner ownerInfo
DB database `toml:"database"`
Servers map[string]server
Clients clients
// Create address type which satisfies the encoding.TextUnmarshaler interface.
type address struct {
*mail.Address
}
type ownerInfo struct {
Name string
Org string `toml:"organization"`
Bio string
DOB time.Time
func (a *address) UnmarshalText(text []byte) error {
var err error
a.Address, err = mail.ParseAddress(string(text))
return err
}
type database struct {
Server string
Ports []int
ConnMax int `toml:"connection_max"`
Enabled bool
// Decode it.
func decode() {
blob := `
contacts = [
"Donald Duck <donald@duckburg.com>",
"Scrooge McDuck <scrooge@duckburg.com>",
]
`
var contacts struct {
Contacts []address
}
type server struct {
IP string
DC string
_, err := toml.Decode(blob, &contacts)
if err != nil {
log.Fatal(err)
}
type clients struct {
Data [][]interface{}
Hosts []string
for _, c := range contacts.Contacts {
fmt.Printf("%#v\n", c.Address)
}
// Output:
// &mail.Address{Name:"Donald Duck", Address:"donald@duckburg.com"}
// &mail.Address{Name:"Scrooge McDuck", Address:"scrooge@duckburg.com"}
}
```
Note that a case insensitive match will be tried if an exact match can't be
found.
To target TOML specifically you can implement `UnmarshalTOML` TOML interface in
a similar way.
A working example of the above can be found in `_examples/example.{go,toml}`.
### More complex usage
See the [`_example/`](/_example) directory for a more complex example.

/*
Package toml provides facilities for decoding and encoding TOML configuration
files via reflection. There is also support for delaying decoding with
the Primitive type, and querying the set of keys in a TOML document with the
MetaData type.
Package toml implements decoding and encoding of TOML files.
The specification implemented: https://github.com/toml-lang/toml
This package supports TOML v1.0.0, as listed on https://toml.io
The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
whether a file is a valid TOML document. It can also be used to print the
type of each key in a TOML document.
There is also support for delaying decoding with the Primitive type, and
querying the set of keys in a TOML document with the MetaData type.
Testing
There are two important types of tests used for this package. The first is
contained inside '*_test.go' files and uses the standard Go unit testing
framework. These tests are primarily devoted to holistically testing the
decoder and encoder.
The second type of testing is used to verify the implementation's adherence
to the TOML specification. These tests have been factored into their own
project: https://github.com/BurntSushi/toml-test
The reason the tests are in a separate project is so that they can be used by
any implementation of TOML. Namely, it is language agnostic.
The github.com/BurntSushi/toml/cmd/tomlv package implements a TOML validator,
and can be used to verify if TOML document is valid. It can also be used to
print the type of each key.

A '\' inside a "-delimited string is interpreted as an escape character.
The following escape sequences are supported:
\b, \t, \n, \f, \r, \", \\, \uXXXX, and \UXXXXXXXX
To prevent a '\' from being recognized as an escape character, use either:
- a ' or '''-delimited string; escape characters aren't processed in them; or
- write two backslashes to get a single backslash: '\\'.
If you're trying to add a Windows path (e.g. "C:\Users\martin") then using '/'
instead of '\' will usually also work: "C:/Users/martin".
`
const usageInlineNewline = `
Inline tables must always be on a single line:
table = {key = 42, second = 43}
It is invalid to split them over multiple lines like so:
# INVALID

Use regular for this:

`
const usageStringNewline = `

This number is too large; this may be an error in the TOML, but it can also be a

int refers to int32 on 32-bit systems and int64 on 64-bit systems.

const usageDuration = `
A duration must be as "number<unit>", without any spaces. Valid units are:
ns nanoseconds (billionth of a second)
us, µs microseconds (millionth of a second)
ms milliseconds (thousands of a second)
s seconds
m minutes
h hours
You can combine multiple units; for example "5m10s" for 5 minutes and 10

**DURATION** defaults to 1m. Prefetching will happen when the TTL drops below **PERCENTAGE**,
which defaults to `10%`, or latest 1 second before TTL expiration. Values should be in the range `[10%, 90%]`.
Note the percent sign is mandatory. **PERCENTAGE** is treated as an `int`.
* `serve_stale`, when serve\_stale is set, cache always will serve an expired entry to a client if there is one
available. When this happens, cache will attempt to refresh the cache entry after sending the expired cache
entry to the client. The responses have a TTL of 0. **DURATION** is how far back to consider
stale responses as fresh. The default duration is 1h.
* `serve_stale`, when serve\_stale is set, cache will always serve an expired entry to a client if there is one
available as long as it has not been expired for longer than **DURATION** (default 1 hour). By default, the _cache_ plugin will
attempt to refresh the cache entry after sending the expired cache entry to the client. The
responses have a TTL of 0. **REFRESH_MODE** controls the timing of the expired cache entry refresh.
`verify` will first verify that an entry is still unavailable from the source before sending the expired entry to the client.
`immediate` will immediately send the expired entry to the client before
checking to see if the entry is available from the source. **REFRESH_MODE** defaults to `immediate`. Setting this
value to `verify` can lead to increased latency when serving stale responses, but will prevent stale entries
from ever being served if an updated response can be retrieved from the source.
* `servfail` cache SERVFAIL responses for **DURATION**. Setting **DURATION** to 0 will disable caching of SERVFAIL
responses. If this option is not set, SERVFAIL responses will be cached for 5 seconds. **DURATION** may not be
greater than 5 minutes.
* `disable` disable the success or denial cache for the listed **ZONES**. If no **ZONES** are given, the specified
cache will be disabled for all zones.

# metadata
## Name
*metadata* - enables a metadata collector.
## Description
By enabling *metadata* any plugin that implements [metadata.Provider
interface](https://godoc.org/github.com/coredns/coredns/plugin/metadata#Provider) will be called for
each DNS query, at the beginning of the process for that query, in order to add its own metadata to
context.
The metadata collected will be available for all plugins, via the Context parameter provided in the
ServeDNS function. The package (code) documentation has examples on how to inspect and retrieve
metadata a plugin might be interested in.
The metadata is added by setting a label with a value in the context. These labels should be named
`plugin/NAME`, where **NAME** is something descriptive. The only hard requirement the *metadata*
plugin enforces is that the labels contain a slash. See the documentation for
`metadata.SetValueFunc`.
The value stored is a string. The empty string signals "no metadata". See the documentation for
`metadata.ValueFunc` on how to retrieve this.
## Syntax
~~~
metadata [ZONES... ]
~~~
* **ZONES** zones metadata should be invoked for.
## Plugins
`metadata.Provider` interface needs to be implemented by each plugin willing to provide metadata
information for other plugins. It will be called by metadata and gather the information from all
plugins in context.
Note: this method should work quickly, because it is called for every request.
## Examples
The *rewrite* plugin uses meta data to rewrite requests.

// Package metadata provides an API that allows plugins to add metadata to the context.
// Each metadata is stored under a label that has the form <plugin>/<name>. Each metadata
// is returned as a Func. When Func is called the metadata is returned. If Func is expensive to
// execute it is its responsibility to provide some form of caching. During the handling of a
// query it is expected the metadata stays constant.
//
// Basic example:
//
// Implement the Provider interface for a plugin p:
//
// func (p P) Metadata(ctx context.Context, state request.Request) context.Context {
// metadata.SetValueFunc(ctx, "test/something", func() string { return "myvalue" })
// return ctx
// }
//
// Basic example with caching:
//
// func (p P) Metadata(ctx context.Context, state request.Request) context.Context {
// cached := ""
// f := func() string {
// if cached != "" {
// return cached
// }
// cached = expensiveFunc()
// return cached
// }
// metadata.SetValueFunc(ctx, "test/something", f)
// return ctx
// }
//
// If you need access to this metadata from another plugin:
//
// // ...
// valueFunc := metadata.ValueFunc(ctx, "test/something")
// value := valueFunc()
// // use 'value'

With *prometheus* you export metrics from CoreDNS and any plugin that has them.
The default location for the metrics is `localhost:9153`. The metrics path is fixed to `/metrics`.
The following metrics are exported:
In addition to the default Go metrics exported by the [Prometheus Go client](https://prometheus.io/docs/guides/go-application/),
the following metrics are exported:
* `coredns_build_info{version, revision, goversion}` - info about CoreDNS itself.
* `coredns_panics_total{}` - total number of panics.
* `coredns_dns_requests_total{server, zone, proto, family, type}` - total query count.
* `coredns_dns_request_duration_seconds{server, zone, type}` - duration to process each query.
* `coredns_dns_request_size_bytes{server, zone, proto}` - size of the request in bytes.
* `coredns_dns_do_requests_total{server, zone}` - queries that have the DO bit set
* `coredns_dns_response_size_bytes{server, zone, proto}` - response size in bytes.
* `coredns_dns_responses_total{server, zone, rcode, plugin}` - response per zone, rcode and plugin.
* `coredns_plugin_enabled{server, zone, name}` - indicates whether a plugin is enabled on per server and zone basis.
* `coredns_dns_requests_total{server, zone, view, proto, family, type}` - total query count.
* `coredns_dns_request_duration_seconds{server, zone, view, type}` - duration to process each query.
* `coredns_dns_request_size_bytes{server, zone, view, proto}` - size of the request in bytes.
* `coredns_dns_do_requests_total{server, view, zone}` - queries that have the DO bit set
* `coredns_dns_response_size_bytes{server, zone, view, proto}` - response size in bytes.
* `coredns_dns_responses_total{server, zone, view, rcode, plugin}` - response per zone, rcode and plugin.
* `coredns_dns_https_responses_total{server, status}` - responses per server and http status code.
* `coredns_plugin_enabled{server, zone, view, name}` - indicates whether a plugin is enabled on per server, zone and view basis.

* `type` which holds the query type. It holds most common types (A, AAAA, MX, SOA, CNAME, PTR, TXT,
NS, SRV, DS, DNSKEY, RRSIG, NSEC, NSEC3, HTTPS, IXFR, AXFR and ANY) and "other" which lumps together all
other types.
* `status` which holds the https status code. Possible values are:
* 200 - request is processed,
* 404 - request has been rejected on validation,
* 400 - request to dns message conversion failed,
* 500 - processing ended up with no response.
* the `plugin` label holds the name of the plugin that made the write to the client. If the server
did the write (on error for instance), the value is empty.
If monitoring is enabled, queries that do not enter the plugin chain are exported under the fake
name "dropped" (without a closing dot - this is never a valid domain name).
Other plugins may export additional stats when the _prometheus_ plugin is enabled. Those stats are documented in each
plugin's README.
This plugin can only be used once per Server Block.
