+go-metrics
+==========
+
+This library provides a `metrics` package which can be used to instrument code,
+expose application metrics, and profile runtime performance in a flexible manner.
+
+Current API: [](https://godoc.org/github.com/armon/go-metrics)
+
+Sinks
+-----
+
+The `metrics` package makes use of a `MetricSink` interface to support delivery
+to any type of backend. Currently the following sinks are provided:
+
+* StatsiteSink : Sinks to a [statsite](https://github.com/armon/statsite/) instance (TCP)
+* StatsdSink: Sinks to a [StatsD](https://github.com/etsy/statsd/) / statsite instance (UDP)
+* PrometheusSink: Sinks to a [Prometheus](http://prometheus.io/) metrics endpoint (exposed via HTTP for scrapes)
+* InmemSink : Provides in-memory aggregation, can be used to export stats
+* FanoutSink : Sinks to multiple sinks. Enables writing to multiple statsite instances for example.
+* BlackholeSink : Sinks to nowhere
+
+In addition to the sinks, the `InmemSignal` can be used to catch a signal,
+and dump a formatted output of recent metrics. For example, when a process gets
+a SIGUSR1, it can dump to stderr recent performance metrics for debugging.
+
+Labels
+------
+
+Most metrics do have an equivalent ending with `WithLabels`, such methods
+allow to push metrics with labels and use some features of underlying Sinks
+(ex: translated into Prometheus labels).
+
+Since some of these labels may increase greatly cardinality of metrics, the
+library allow to filter labels using a blacklist/whitelist filtering system
+which is global to all metrics.
+
+* If `Config.AllowedLabels` is not nil, then only labels specified in this value will be sent to underlying Sink, otherwise, all labels are sent by default.
+* If `Config.BlockedLabels` is not nil, any label specified in this value will not be sent to underlying Sinks.
+
+By default, both `Config.AllowedLabels` and `Config.BlockedLabels` are nil, meaning that
+no tags are filetered at all, but it allow to a user to globally block some tags with high
+cardinality at application level.
+
+Examples
+--------
+
+Here is an example of using the package:
+
+```go
+func SlowMethod() {
+ // Profiling the runtime of a method
+ defer metrics.MeasureSince([]string{"SlowMethod"}, time.Now())
+}
+
+// Configure a statsite sink as the global metrics sink
+sink, _ := metrics.NewStatsiteSink("statsite:8125")
+metrics.NewGlobal(metrics.DefaultConfig("service-name"), sink)
+
+// Emit a Key/Value pair
+metrics.EmitKey([]string{"questions", "meaning of life"}, 42)
+```
+
+Here is an example of setting up a signal handler:
+
+```go
+// Setup the inmem sink and signal handler
+inm := metrics.NewInmemSink(10*time.Second, time.Minute)
+sig := metrics.DefaultInmemSignal(inm)
+metrics.NewGlobal(metrics.DefaultConfig("service-name"), inm)
+
+// Run some code
+inm.SetGauge([]string{"foo"}, 42)
+inm.EmitKey([]string{"bar"}, 30)
+
+inm.IncrCounter([]string{"baz"}, 42)
+inm.IncrCounter([]string{"baz"}, 1)
+inm.IncrCounter([]string{"baz"}, 80)
+
+inm.AddSample([]string{"method", "wow"}, 42)
+inm.AddSample([]string{"method", "wow"}, 100)
+inm.AddSample([]string{"method", "wow"}, 22)
+
+....
+```
+

+# capnslog, the CoreOS logging package
+
+There are far too many logging packages out there, with varying degrees of licenses, far too many features (colorization, all sorts of log frameworks) or are just a pain to use (lack of `Fatalln()`?).
+capnslog provides a simple but consistent logging interface suitable for all kinds of projects.
+
+### Design Principles
+
+##### `package main` is the place where logging gets turned on and routed
+
+A library should not touch log options, only generate log entries. Libraries are silent until main lets them speak.
+
+##### All log options are runtime-configurable.
+
+Still the job of `main` to expose these configurations. `main` may delegate this to, say, a configuration webhook, but does so explicitly.
+
+##### There is one log object per package. It is registered under its repository and package name.
+
+`main` activates logging for its repository and any dependency repositories it would also like to have output in its logstream. `main` also dictates at which level each subpackage logs.
+
+##### There is *one* output stream, and it is an `io.Writer` composed with a formatter.
+
+Splitting streams is probably not the job of your program, but rather, your log aggregation framework. If you must split output streams, again, `main` configures this and you can write a very simple two-output struct that satisfies io.Writer.
+
+Fancy colorful formatting and JSON output are beyond the scope of a basic logging framework -- they're application/log-collector dependent. These are, at best, provided as options, but more likely, provided by your application.
+
+##### Log objects are an interface
+
+An object knows best how to print itself. Log objects can collect more interesting metadata if they wish, however, because text isn't going away anytime soon, they must all be marshalable to text. The simplest log object is a string, which returns itself. If you wish to do more fancy tricks for printing your log objects, see also JSON output -- introspect and write a formatter which can handle your advanced log interface. Making strings is the only thing guaranteed.
+
+##### Log levels have specific meanings:
+
+ * Critical: Unrecoverable. Must fail.
+ * Error: Data has been lost, a request has failed for a bad reason, or a required resource has been lost
+ * Warning: (Hopefully) Temporary conditions that may cause errors, but may work fine. A replica disappearing (that may reconnect) is a warning.
+ * Notice: Normal, but important (uncommon) log information.
+ * Info: Normal, working log information, everything is fine, but helpful notices for auditing or common operations.
+ * Debug: Everything is still fine, but even common operations may be logged, and less helpful but more quantity of notices.
+ * Trace: Anything goes, from logging every function call as part of a common operation, to tracing execution of a query.

+Package gogoproto provides extensions for protocol buffers to achieve:
+
+ - fast marshalling and unmarshalling.
+ - peace of mind by optionally generating test and benchmark code.
+ - more canonical Go structures.
+ - less typing by optionally generating extra helper code.
+ - goprotobuf compatibility
+
+More Canonical Go Structures
+
+A lot of time working with a goprotobuf struct will lead you to a place where you create another struct that is easier to work with and then have a function to copy the values between the two structs.
+You might also find that basic structs that started their life as part of an API need to be sent over the wire. With gob, you could just send it. With goprotobuf, you need to make a parallel struct.
+Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions.
+
+ - nullable, if false, a field is generated without a pointer (see warning below).
+ - embed, if true, the field is generated as an embedded field.
+ - customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128
+ - customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames.
+ - casttype (beta), Changes the generated fieldtype. All generated code assumes that this type is castable to the protocol buffer field type. It does not work for structs or enums.
+ - castkey (beta), Changes the generated fieldtype for a map key. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
+ - castvalue (beta), Changes the generated fieldtype for a map value. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
+
+Warning about nullable: According to the Protocol Buffer specification, you should be able to tell whether a field is set or unset. With the option nullable=false this feature is lost, since your non-nullable fields will always be set. It can be seen as a layer on top of Protocol Buffers, where before and after marshalling all non-nullable fields are set and they cannot be unset.
+
+Let us look at:
+
+ github.com/gogo/protobuf/test/example/example.proto
+
+for a quicker overview.
+
+The following message:
+
+ package test;
+
+ import "github.com/gogo/protobuf/gogoproto/gogo.proto";
+
+ message A {
+ optional string Description = 1 [(gogoproto.nullable) = false];
+ optional int64 Number = 2 [(gogoproto.nullable) = false];
+ optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
+ }
+
+Will generate a go struct which looks a lot like this:
+
+ type A struct {
+ Description string
+ Number int64
+ Id github_com_gogo_protobuf_test_custom.Uuid
+ }
+
+You will see there are no pointers, since all fields are non-nullable.
+You will also see a custom type which marshals to a string.
+Be warned it is your responsibility to test your custom types thoroughly.
+You should think of every possible empty and nil case for your marshaling, unmarshaling and size methods.
+
+Next we will embed the message A in message B.
+
+ message B {
+ optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
+ repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
+ }
+
+See below that A is embedded in B.
+
+ type B struct {
+ A
+ G []github_com_gogo_protobuf_test_custom.Uint128
+ }
+
+Also see the repeated custom type.
+
+ type Uint128 [2]uint64
+
+Next we will create a custom name for one of our fields.
+
+ message C {
+ optional int64 size = 1 [(gogoproto.customname) = "MySize"];
+ }
+
+See below that the field's name is MySize and not Size.
+
+ type C struct {
+ MySize *int64
+ }
+
+The is useful when having a protocol buffer message with a field name which conflicts with a generated method.
+As an example, having a field name size and using the sizer plugin to generate a Size method will cause a go compiler error.
+Using customname you can fix this error without changing the field name.
+This is typically useful when working with a protocol buffer that was designed before these methods and/or the go language were avialable.
+
+Gogoprotobuf also has some more subtle changes, these could be changed back:
+
+ - the generated package name for imports do not have the extra /filename.pb,
+ but are actually the imports specified in the .proto file.
+
+Gogoprotobuf also has lost some features which should be brought back with time:
+
+ - Marshalling and unmarshalling with reflect and without the unsafe package,
+ this requires work in pointer_reflect.go
+
+Why does nullable break protocol buffer specifications:
+
+The protocol buffer specification states, somewhere, that you should be able to tell whether a
+field is set or unset. With the option nullable=false this feature is lost,
+since your non-nullable fields will always be set. It can be seen as a layer on top of
+protocol buffers, where before and after marshalling all non-nullable fields are set
+and they cannot be unset.
+
+Goprotobuf Compatibility:
+
+Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers.
+Gogoprotobuf generates the same code as goprotobuf if no extensions are used.
+The enumprefix, getters and stringer extensions can be used to remove some of the unnecessary code generated by goprotobuf:
+
+ - gogoproto_import, if false, the generated code imports github.com/golang/protobuf/proto instead of github.com/gogo/protobuf/proto.
+ - goproto_enum_prefix, if false, generates the enum constant names without the messagetype prefix
+ - goproto_enum_stringer (experimental), if false, the enum is generated without the default string method, this is useful for rather using enum_stringer, or allowing you to write your own string method.
+ - goproto_getters, if false, the message is generated without get methods, this is useful when you would rather want to use face
+ - goproto_stringer, if false, the message is generated without the default string method, this is useful for rather using stringer, or allowing you to write your own string method.
+ - goproto_extensions_map (beta), if false, the extensions field is generated as type []byte instead of type map[int32]proto.Extension
+ - goproto_unrecognized (beta), if false, XXX_unrecognized field is not generated. This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields.
+ - goproto_registration (beta), if true, the generated files will register all messages and types against both gogo/protobuf and golang/protobuf. This is necessary when using third-party packages which read registrations from golang/protobuf (such as the grpc-gateway).
+
+Less Typing and Peace of Mind is explained in their specific plugin folders godoc:
+
+ - github.com/gogo/protobuf/plugin/<extension_name>
+
+If you do not use any of these extension the code that is generated
+will be the same as if goprotobuf has generated it.
+
+The most complete way to see examples is to look at
+
+ github.com/gogo/protobuf/test/thetest.proto
+
+Gogoprototest is a seperate project,
+because we want to keep gogoprotobuf independent of goprotobuf,
+but we still want to test it thoroughly.

+Package proto converts data structures to and from the wire format of
+protocol buffers. It works in concert with the Go source code generated
+for .proto files by the protocol compiler.
+
+A summary of the properties of the protocol buffer interface
+for a protocol buffer variable v:
+
+ - Names are turned from camel_case to CamelCase for export.
+ - There are no methods on v to set fields; just treat
+ them as structure fields.
+ - There are getters that return a field's value if set,
+ and return the field's default value if unset.
+ The getters work even if the receiver is a nil message.
+ - The zero value for a struct is its correct initialization state.
+ All desired fields must be set before marshaling.
+ - A Reset() method will restore a protobuf struct to its zero state.
+ - Non-repeated fields are pointers to the values; nil means unset.
+ That is, optional or required field int32 f becomes F *int32.
+ - Repeated fields are slices.
+ - Helper functions are available to aid the setting of fields.
+ msg.Foo = proto.String("hello") // set field
+ - Constants are defined to hold the default values of all fields that
+ have them. They have the form Default_StructName_FieldName.
+ Because the getter methods handle defaulted values,
+ direct use of these constants should be rare.
+ - Enums are given type names and maps from names to values.
+ Enum values are prefixed by the enclosing message's name, or by the
+ enum's type name if it is a top-level enum. Enum types have a String
+ method, and a Enum method to assist in message construction.
+ - Nested messages, groups and enums have type names prefixed with the name of
+ the surrounding message type.
+ - Extensions are given descriptor names that start with E_,
+ followed by an underscore-delimited list of the nested messages
+ that contain it (if any) followed by the CamelCased name of the
+ extension field itself. HasExtension, ClearExtension, GetExtension
+ and SetExtension are functions for manipulating extensions.
+ - Oneof field sets are given a single field in their message,
+ with distinguished wrapper types for each possible field value.
+ - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+When the .proto file specifies `syntax="proto3"`, there are some differences:
+
+ - Non-repeated fields of non-message type are values instead of pointers.
+ - Enum types do not get an Enum method.
+
+The simplest way to describe this is to see an example.
+Given file test.proto, containing
+
+ package example;
+
+ enum FOO { X = 17; }
+
+ message Test {
+ required string label = 1;
+ optional int32 type = 2 [default=77];
+ repeated int64 reps = 3;

+ // Let's look at just the field definition:
+ // optional string foo = 1;
+ // ^ ^^ ^^ ^ ^^^

+ // [g,h) [ 4, 0, 2, 0, 3 ] The number (1).
+ //
+ // Notes:
+ // - A location may refer to a repeated field itself (i.e. not to any
+ // particular index within it). This is used whenever a set of elements are
+ // logically enclosed in a single code segment. For example, an entire
+ // extend block (possibly containing multiple extension definitions) will
+ // have an outer location whose path refers to the "extensions" repeated
+ // field without an index.
+ // - Multiple locations may have the same path. This happens when a single
+ // logical declaration is spread out across multiple places. The most
+ // obvious example is the "extend" block again -- there may be multiple
+ // extend blocks in the same scope, each of which will have the same path.
+ // - A location's span is not always a subset of its parent's span. For
+ // example, the "extendee" of an extension declaration appears at the
+ // beginning of the "extend" block and is shared by all extensions within
+ // the block.
+ // - Just because a location's span is a subset of some other location's span
+ // does not mean that it is a descendent. For example, a "group" defines
+ // both a type and a field in a single declaration. Thus, the locations
+ // corresponding to the type and field and their components will overlap.
+ // - Code which tries to interpret locations should probably be designed to
+ // ignore those that it doesn't understand, as more types of locations could
+ // be recorded in the future.

+# uuid 
+The uuid package generates and inspects UUIDs based on
+[RFC 4122](http://tools.ietf.org/html/rfc4122)
+and DCE 1.1: Authentication and Security Services.
+
+This package is based on the github.com/pborman/uuid package (previously named
+code.google.com/p/go-uuid). It differs from these earlier packages in that
+a UUID is a 16 byte array rather than a byte slice. One loss due to this
+change is the ability to represent an invalid UUID (vs a NIL UUID).
+
+###### Install
+`go get github.com/google/uuid`
+
+###### Documentation
+[](http://godoc.org/github.com/google/uuid)
+
+Full `go doc` style documentation for the package can be viewed online without
+installing this package by using the GoDoc site here:

+
+2. License Grants and Conditions
+
+2.1. Grants
+
+ Each Contributor hereby grants You a world-wide, royalty-free,
+ non-exclusive license:
+
+ a. under intellectual property rights (other than patent or trademark)
+ Licensable by such Contributor to use, reproduce, make available,
+ modify, display, perform, distribute, and otherwise exploit its

+ or its Contributor Version.
+
+2.2. Effective Date
+
+ The licenses granted in Section 2.1 with respect to any Contribution become
+ effective for each Contribution on the date the Contributor first distributes
+ such Contribution.
+
+2.3. Limitations on Grant Scope
+
+ The licenses granted in this Section 2 are the only rights granted under this
+ License. No additional rights or licenses will be implied from the distribution
+ or licensing of Covered Software under this License. Notwithstanding Section
+ 2.1(b) above, no patent license is granted by a Contributor:
+
+ a. for any code that a Contributor has removed from Covered Software; or
+
+ b. for infringements caused by: (i) Your and any other third party’s
+ modifications of Covered Software, or (ii) the combination of its
+ Contributions with other software (except as part of its Contributor
+ Version); or
+
+ c. under Patent Claims infringed by Covered Software in the absence of its
+ Contributions.
+
+ This License does not grant any rights in the trademarks, service marks, or
+ logos of any Contributor (except as may be necessary to comply with the
+ notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+ No Contributor makes additional grants as a result of Your choice to
+ distribute the Covered Software under a subsequent version of this License
+ (see Section 10.2) or under the terms of a Secondary License (if permitted
+ under the terms of Section 3.3).
+
+2.5. Representation
+
+ Each Contributor represents that the Contributor believes its Contributions
+ are its original creation(s) or it has sufficient rights to grant the
+ rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+ This License is not intended to limit any rights You have under applicable
+ copyright doctrines of fair use, fair dealing, or other equivalents.
+
+2.7. Conditions
+
+ Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+ Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+ All distribution of Covered Software in Source Code Form, including any
+ Modifications that You create or to which You contribute, must be under the
+ terms of this License. You must inform recipients that the Source Code Form
+ of the Covered Software is governed by the terms of this License, and how
+ they can obtain a copy of this License. You may not attempt to alter or
+ restrict the recipients’ rights in the Source Code Form.
+
+3.2. Distribution of Executable Form
+
+ If You distribute Covered Software in Executable Form then:
+
+ a. such Covered Software must also be made available in Source Code Form,
+ as described in Section 3.1, and You must inform recipients of the
+ Executable Form how they can obtain a copy of such Source Code Form by
+ reasonable means in a timely manner, at a charge no more than the cost
+ of distribution to the recipient; and
+
+ b. You may distribute such Executable Form under the terms of this License,
+ or sublicense it under different terms, provided that the license for
+ the Executable Form does not attempt to limit or alter the recipients’
+ rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for the
+ Covered Software. If the Larger Work is a combination of Covered Software
+ with a work governed by one or more Secondary Licenses, and the Covered
+ Software is not Incompatible With Secondary Licenses, this License permits
+ You to additionally distribute such Covered Software under the terms of
+ such Secondary License(s), so that the recipient of the Larger Work may, at
+ their option, further distribute the Covered Software under the terms of
+ either this License or such Secondary License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices (including
+ copyright notices, patent notices, disclaimers of warranty, or limitations
+ of liability) contained within the Source Code Form of the Covered
+ Software, except that You may alter any license notices to the extent
+ required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on behalf
+ of any Contributor. You must make it absolutely clear that any such
+ warranty, support, indemnity, or liability obligation is offered by You
+ alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute, judicial
+ order, or regulation then You must: (a) comply with the terms of this License
+ to the maximum extent possible; and (b) describe the limitations and the code
+ they affect. Such description must be placed in a text file included with all
+ distributions of the Covered Software under this License. Except to the
+ extent prohibited by statute or regulation, such description must be
+ sufficiently detailed for a recipient of ordinary skill to be able to
+ understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing basis,
+ if such Contributor fails to notify You of the non-compliance by some
+ reasonable means prior to 60 days after You have come back into compliance.
+ Moreover, Your grants from a particular Contributor are reinstated on an
+ ongoing basis if such Contributor notifies You of the non-compliance by
+ some reasonable means, this is the first time You have received notice of
+ non-compliance with this License from such Contributor, and You become
+ compliant prior to 30 days after Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions, counter-claims,
+ and cross-claims) alleging that a Contributor Version directly or
+ indirectly infringes any patent, then the rights granted to You by any and
+ all Contributors for the Covered Software under Section 2.1 of this License
+ shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an “as is” basis, without
+ warranty of any kind, either expressed, implied, or statutory, including,
+ without limitation, warranties that the Covered Software is free of defects,
+ merchantable, fit for a particular purpose or non-infringing. The entire
+ risk as to the quality and performance of the Covered Software is with You.
+ Should any Covered Software prove defective in any respect, You (not any
+ Contributor) assume the cost of any necessary servicing, repair, or
+ correction. This disclaimer of warranty constitutes an essential part of this
+ License. No use of any Covered Software is authorized under this License
+ except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from such
+ party’s negligence to the extent applicable law prohibits such limitation.
+ Some jurisdictions do not allow the exclusion or limitation of incidental or
+ consequential damages, so this exclusion and limitation may not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts of
+ a jurisdiction where the defendant maintains its principal place of business
+ and such litigation shall be governed by laws of that jurisdiction, without
+ reference to its conflict-of-law provisions. Nothing in this Section shall
+ prevent a party’s ability to bring cross-claims or counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject matter
+ hereof. If any provision of this License is held to be unenforceable, such
+ provision shall be reformed only to the extent necessary to make it
+ enforceable. Any law or regulation which provides that the language of a
+ contract shall be construed against the drafter shall not be used to construe
+ this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+ Mozilla Foundation is the license steward. Except as provided in Section
+ 10.3, no one other than the license steward has the right to modify or
+ publish new versions of this License. Each version will be given a
+ distinguishing version number.
+
+10.2. Effect of New Versions
+
+ You may distribute the Covered Software under the terms of the version of
+ the License under which You originally received the Covered Software, or
+ under the terms of any subsequent version published by the license
+ steward.
+
+10.3. Modified Versions
+
+ If you create software not governed by this License, and you want to
+ create a new license for such software, you may create and use a modified
+ version of this License if you rename the license and remove any
+ references to the name of the license steward (except to note that such
+ modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
+ If You choose to distribute Source Code Form that is Incompatible With
+ Secondary Licenses under the terms of this version of the License, the
+ notice described in Exhibit B of this License must be attached.
+
+Exhibit A - Source Code Form License Notice

+Consul API client
+=================
+
+This package provides the `api` package which attempts to
+provide programmatic access to the full Consul API.
+
+Currently, all of the Consul APIs included in version 0.6.0 are supported.
+
+Documentation
+=============
+
+The full documentation is available on [Godoc](https://godoc.org/github.com/hashicorp/consul/api)
+
+Usage
+=====
+
+Below is an example of using the Consul client:
+
+```go
+package main
+
+import "github.com/hashicorp/consul/api"
+import "fmt"
+
+func main() {
+ // Get a new client
+ client, err := api.NewClient(api.DefaultConfig())
+ if err != nil {
+ panic(err)
+ }
+
+ // Get a handle to the KV API
+ kv := client.KV()
+
+ // PUT a new KV pair
+ p := &api.KVPair{Key: "REDIS_MAXCLIENTS", Value: []byte("1000")}
+ _, err = kv.Put(p, nil)
+ if err != nil {
+ panic(err)
+ }
+
+ // Lookup the pair
+ pair, _, err := kv.Get("REDIS_MAXCLIENTS", nil)
+ if err != nil {
+ panic(err)
+ }
+ fmt.Printf("KV: %v %s\n", pair.Key, pair.Value)
+}
+```
+
+To run this example, start a Consul server:
+
+```bash
+consul agent -dev
+```
+
+Copy the code above into a file such as `main.go`.
+
+Install and run. You'll see a key (`REDIS_MAXCLIENTS`) and value (`1000`) printed.
+
+```bash
+$ go get
+$ go run main.go
+KV: REDIS_MAXCLIENTS 1000
+```
+
+After running the code, you can also view the values in the Consul UI on your local machine at http://localhost:8500/ui/dc1/kv

+ non-exclusive license:
+
+ a. under intellectual property rights (other than patent or trademark)
+ Licensable by such Contributor to use, reproduce, make available,
+ modify, display, perform, distribute, and otherwise exploit its

+ Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+ The licenses granted in Section 2.1 with respect to any Contribution
+ become effective for each Contribution on the date the Contributor first
+ distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+ The licenses granted in this Section 2 are the only rights granted under
+ this License. No additional rights or licenses will be implied from the
+ distribution or licensing of Covered Software under this License.
+ Notwithstanding Section 2.1(b) above, no patent license is granted by a
+ Contributor:
+
+ a. for any code that a Contributor has removed from Covered Software; or
+
+ b. for infringements caused by: (i) Your and any other third party's
+ modifications of Covered Software, or (ii) the combination of its
+ Contributions with other software (except as part of its Contributor
+ Version); or
+
+ c. under Patent Claims infringed by Covered Software in the absence of
+ its Contributions.
+
+ This License does not grant any rights in the trademarks, service marks,
+ or logos of any Contributor (except as may be necessary to comply with
+ the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+ No Contributor makes additional grants as a result of Your choice to
+ distribute the Covered Software under a subsequent version of this
+ License (see Section 10.2) or under the terms of a Secondary License (if
+ permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+ Each Contributor represents that the Contributor believes its
+ Contributions are its original creation(s) or it has sufficient rights to
+ grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+ This License is not intended to limit any rights You have under
+ applicable copyright doctrines of fair use, fair dealing, or other
+ equivalents.
+
+2.7. Conditions
+
+ Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+ Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+ All distribution of Covered Software in Source Code Form, including any
+ Modifications that You create or to which You contribute, must be under
+ the terms of this License. You must inform recipients that the Source
+ Code Form of the Covered Software is governed by the terms of this
+ License, and how they can obtain a copy of this License. You may not
+ attempt to alter or restrict the recipients' rights in the Source Code
+ Form.
+
+3.2. Distribution of Executable Form
+
+ If You distribute Covered Software in Executable Form then:
+
+ a. such Covered Software must also be made available in Source Code Form,
+ as described in Section 3.1, and You must inform recipients of the
+ Executable Form how they can obtain a copy of such Source Code Form by
+ reasonable means in a timely manner, at a charge no more than the cost
+ of distribution to the recipient; and
+
+ b. You may distribute such Executable Form under the terms of this
+ License, or sublicense it under different terms, provided that the
+ license for the Executable Form does not attempt to limit or alter the
+ recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for
+ the Covered Software. If the Larger Work is a combination of Covered
+ Software with a work governed by one or more Secondary Licenses, and the
+ Covered Software is not Incompatible With Secondary Licenses, this
+ License permits You to additionally distribute such Covered Software
+ under the terms of such Secondary License(s), so that the recipient of
+ the Larger Work may, at their option, further distribute the Covered
+ Software under the terms of either this License or such Secondary
+ License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices
+ (including copyright notices, patent notices, disclaimers of warranty, or
+ limitations of liability) contained within the Source Code Form of the
+ Covered Software, except that You may alter any license notices to the
+ extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on
+ behalf of any Contributor. You must make it absolutely clear that any
+ such warranty, support, indemnity, or liability obligation is offered by
+ You alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute,
+ judicial order, or regulation then You must: (a) comply with the terms of
+ this License to the maximum extent possible; and (b) describe the
+ limitations and the code they affect. Such description must be placed in a
+ text file included with all distributions of the Covered Software under
+ this License. Except to the extent prohibited by statute or regulation,
+ such description must be sufficiently detailed for a recipient of ordinary
+ skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing
+ basis, if such Contributor fails to notify You of the non-compliance by
+ some reasonable means prior to 60 days after You have come back into
+ compliance. Moreover, Your grants from a particular Contributor are
+ reinstated on an ongoing basis if such Contributor notifies You of the
+ non-compliance by some reasonable means, this is the first time You have
+ received notice of non-compliance with this License from such
+ Contributor, and You become compliant prior to 30 days after Your receipt
+ of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions,
+ counter-claims, and cross-claims) alleging that a Contributor Version
+ directly or indirectly infringes any patent, then the rights granted to
+ You by any and all Contributors for the Covered Software under Section
+ 2.1 of this License shall terminate.

+
+Functions for accessing "clean" Go http.Client values
+
+-------------
+
+The Go standard library contains a default `http.Client` called
+`http.DefaultClient`. It is a common idiom in Go code to start with
+`http.DefaultClient` and tweak it as necessary, and in fact, this is
+encouraged; from the `http` package documentation:
+
+> The Client's Transport typically has internal state (cached TCP connections),
+so Clients should be reused instead of created as needed. Clients are safe for
+concurrent use by multiple goroutines.
+
+Unfortunately, this is a shared value, and it is not uncommon for libraries to
+assume that they are free to modify it at will. With enough dependencies, it
+can be very easy to encounter strange problems and race conditions due to
+manipulation of this shared value across libraries and goroutines (clients are
+safe for concurrent use, but writing values to the client struct itself is not
+protected).
+
+Making things worse is the fact that a bare `http.Client` will use a default
+`http.Transport` called `http.DefaultTransport`, which is another global value
+that behaves the same way. So it is not simply enough to replace
+`http.DefaultClient` with `&http.Client{}`.
+
+This repository provides some simple functions to get a "clean" `http.Client`
+-- one that uses the same default values as the Go standard library, but
+returns a client that does not share any state with other clients.

+ grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+ This License is not intended to limit any rights You have under
+ applicable copyright doctrines of fair use, fair dealing, or other
+ equivalents.
+
+2.7. Conditions
+
+ Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+ Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+ All distribution of Covered Software in Source Code Form, including any
+ Modifications that You create or to which You contribute, must be under
+ the terms of this License. You must inform recipients that the Source
+ Code Form of the Covered Software is governed by the terms of this
+ License, and how they can obtain a copy of this License. You may not
+ attempt to alter or restrict the recipients' rights in the Source Code
+ Form.
+
+3.2. Distribution of Executable Form
+
+ If You distribute Covered Software in Executable Form then:
+
+ a. such Covered Software must also be made available in Source Code Form,
+ as described in Section 3.1, and You must inform recipients of the
+ Executable Form how they can obtain a copy of such Source Code Form by
+ reasonable means in a timely manner, at a charge no more than the cost
+ of distribution to the recipient; and
+
+ b. You may distribute such Executable Form under the terms of this
+ License, or sublicense it under different terms, provided that the
+ license for the Executable Form does not attempt to limit or alter the
+ recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for
+ the Covered Software. If the Larger Work is a combination of Covered
+ Software with a work governed by one or more Secondary Licenses, and the
+ Covered Software is not Incompatible With Secondary Licenses, this
+ License permits You to additionally distribute such Covered Software
+ under the terms of such Secondary License(s), so that the recipient of
+ the Larger Work may, at their option, further distribute the Covered
+ Software under the terms of either this License or such Secondary
+ License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices
+ (including copyright notices, patent notices, disclaimers of warranty, or
+ limitations of liability) contained within the Source Code Form of the
+ Covered Software, except that You may alter any license notices to the
+ extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on
+ behalf of any Contributor. You must make it absolutely clear that any
+ such warranty, support, indemnity, or liability obligation is offered by
+ You alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute,
+ judicial order, or regulation then You must: (a) comply with the terms of
+ this License to the maximum extent possible; and (b) describe the
+ limitations and the code they affect. Such description must be placed in a
+ text file included with all distributions of the Covered Software under
+ this License. Except to the extent prohibited by statute or regulation,
+ such description must be sufficiently detailed for a recipient of ordinary
+ skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing
+ basis, if such Contributor fails to notify You of the non-compliance by
+ some reasonable means prior to 60 days after You have come back into
+ compliance. Moreover, Your grants from a particular Contributor are
+ reinstated on an ongoing basis if such Contributor notifies You of the
+ non-compliance by some reasonable means, this is the first time You have
+ received notice of non-compliance with this License from such
+ Contributor, and You become compliant prior to 30 days after Your receipt
+ of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions,
+ counter-claims, and cross-claims) alleging that a Contributor Version
+ directly or indirectly infringes any patent, then the rights granted to
+ You by any and all Contributors for the Covered Software under Section
+ 2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an "as is" basis,
+ without warranty of any kind, either expressed, implied, or statutory,
+ including, without limitation, warranties that the Covered Software is free
+ of defects, merchantable, fit for a particular purpose or non-infringing.
+ The entire risk as to the quality and performance of the Covered Software
+ is with You. Should any Covered Software prove defective in any respect,
+ You (not any Contributor) assume the cost of any necessary servicing,
+ repair, or correction. This disclaimer of warranty constitutes an essential
+ part of this License. No use of any Covered Software is authorized under
+ this License except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from
+ such party's negligence to the extent applicable law prohibits such
+ limitation. Some jurisdictions do not allow the exclusion or limitation of
+ incidental or consequential damages, so this exclusion and limitation may
+ not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts
+ of a jurisdiction where the defendant maintains its principal place of
+ business and such litigation shall be governed by laws of that
+ jurisdiction, without reference to its conflict-of-law provisions. Nothing
+ in this Section shall prevent a party's ability to bring cross-claims or
+ counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject
+ matter hereof. If any provision of this License is held to be
+ unenforceable, such provision shall be reformed only to the extent
+ necessary to make it enforceable. Any law or regulation which provides that
+ the language of a contract shall be construed against the drafter shall not
+ be used to construe this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+ Mozilla Foundation is the license steward. Except as provided in Section
+ 10.3, no one other than the license steward has the right to modify or
+ publish new versions of this License. Each version will be given a

+ If you create software not governed by this License, and you want to
+ create a new license for such software, you may create and use a
+ modified version of this License if you rename the license and remove
+ any references to the name of the license steward (except to note that
+ such modified license differs from this License).

+go-immutable-radix [](https://travis-ci.org/hashicorp/go-immutable-radix)
+=========
+
+Provides the `iradix` package that implements an immutable [radix tree](http://en.wikipedia.org/wiki/Radix_tree).
+The package only provides a single `Tree` implementation, optimized for sparse nodes.
+
+As a radix tree, it provides the following:
+ * O(k) operations. In many cases, this can be faster than a hash table since
+ the hash function is an O(k) operation, and hash tables have very poor cache locality.
+ * Minimum / Maximum value lookups
+ * Ordered iteration
+
+A tree supports using a transaction to batch multiple updates (insert, delete)
+in a more efficient manner than performing each operation one at a time.
+
+For a mutable variant, see [go-radix](https://github.com/armon/go-radix).
+
+Documentation
+=============
+
+The full documentation is available on [Godoc](http://godoc.org/github.com/hashicorp/go-immutable-radix).
+
+Example
+=======
+
+Below is a simple example of usage
+
+```go
+// Create a tree
+r := iradix.New()
+r, _, _ = r.Insert([]byte("foo"), 1)
+r, _, _ = r.Insert([]byte("bar"), 2)
+r, _, _ = r.Insert([]byte("foobar"), 2)
+
+// Find the longest prefix match
+m, _, _ := r.Root().LongestPrefix([]byte("foozip"))
+if string(m) != "foo" {
+ panic("should be foo")
+}
+```
+
+Here is an example of performing a range scan of the keys.
+
+```go
+// Create a tree
+r := iradix.New()
+r, _, _ = r.Insert([]byte("001"), 1)
+r, _, _ = r.Insert([]byte("002"), 2)
+r, _, _ = r.Insert([]byte("005"), 5)
+r, _, _ = r.Insert([]byte("010"), 10)
+r, _, _ = r.Insert([]byte("100"), 10)
+
+// Range scan over the keys that sort lexicographically between [003, 050)
+it := r.Root().Iterator()
+it.SeekLowerBound([]byte("003"))
+for key, _, ok := it.Next(); ok; key, _, ok = it.Next() {
+ if key >= "050" {
+ break
+ }
+ fmt.Println(key)
+}
+// Output:
+// 005
+// 010
+```

+ license for the Executable Form does not attempt to limit or alter the
+ recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for
+ the Covered Software. If the Larger Work is a combination of Covered
+ Software with a work governed by one or more Secondary Licenses, and the
+ Covered Software is not Incompatible With Secondary Licenses, this
+ License permits You to additionally distribute such Covered Software
+ under the terms of such Secondary License(s), so that the recipient of
+ the Larger Work may, at their option, further distribute the Covered
+ Software under the terms of either this License or such Secondary
+ License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices
+ (including copyright notices, patent notices, disclaimers of warranty, or
+ limitations of liability) contained within the Source Code Form of the
+ Covered Software, except that You may alter any license notices to the
+ extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on
+ behalf of any Contributor. You must make it absolutely clear that any
+ such warranty, support, indemnity, or liability obligation is offered by
+ You alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute,
+ judicial order, or regulation then You must: (a) comply with the terms of
+ this License to the maximum extent possible; and (b) describe the
+ limitations and the code they affect. Such description must be placed in a
+ text file included with all distributions of the Covered Software under
+ this License. Except to the extent prohibited by statute or regulation,
+ such description must be sufficiently detailed for a recipient of ordinary
+ skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing
+ basis, if such Contributor fails to notify You of the non-compliance by
+ some reasonable means prior to 60 days after You have come back into
+ compliance. Moreover, Your grants from a particular Contributor are
+ reinstated on an ongoing basis if such Contributor notifies You of the
+ non-compliance by some reasonable means, this is the first time You have
+ received notice of non-compliance with this License from such
+ Contributor, and You become compliant prior to 30 days after Your receipt
+ of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions,
+ counter-claims, and cross-claims) alleging that a Contributor Version
+ directly or indirectly infringes any patent, then the rights granted to
+ You by any and all Contributors for the Covered Software under Section
+ 2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an "as is" basis,
+ without warranty of any kind, either expressed, implied, or statutory,
+ including, without limitation, warranties that the Covered Software is free
+ of defects, merchantable, fit for a particular purpose or non-infringing.
+ The entire risk as to the quality and performance of the Covered Software
+ is with You. Should any Covered Software prove defective in any respect,
+ You (not any Contributor) assume the cost of any necessary servicing,
+ repair, or correction. This disclaimer of warranty constitutes an essential
+ part of this License. No use of any Covered Software is authorized under
+ this License except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from
+ such party's negligence to the extent applicable law prohibits such
+ limitation. Some jurisdictions do not allow the exclusion or limitation of
+ incidental or consequential damages, so this exclusion and limitation may
+ not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts
+ of a jurisdiction where the defendant maintains its principal place of
+ business and such litigation shall be governed by laws of that
+ jurisdiction, without reference to its conflict-of-law provisions. Nothing
+ in this Section shall prevent a party's ability to bring cross-claims or
+ counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject
+ matter hereof. If any provision of this License is held to be
+ unenforceable, such provision shall be reformed only to the extent
+ necessary to make it enforceable. Any law or regulation which provides that
+ the language of a contract shall be construed against the drafter shall not
+ be used to construe this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+ Mozilla Foundation is the license steward. Except as provided in Section
+ 10.3, no one other than the license steward has the right to modify or
+ publish new versions of this License. Each version will be given a

+# rootcerts
+
+Functions for loading root certificates for TLS connections.
+
+-----
+
+Go's standard library `crypto/tls` provides a common mechanism for configuring
+TLS connections in `tls.Config`. The `RootCAs` field on this struct is a pool
+of certificates for the client to use as a trust store when verifying server
+certificates.
+
+This library contains utility functions for loading certificates destined for
+that field, as well as one other important thing:
+
+When the `RootCAs` field is `nil`, the standard library attempts to load the
+host's root CA set. This behavior is OS-specific, and the Darwin
+implementation contains [a bug that prevents trusted certificates from the
+System and Login keychains from being loaded][1]. This library contains
+Darwin-specific behavior that works around that bug.
+
+[1]: https://github.com/golang/go/issues/14514
+
+## Example Usage
+
+Here's a snippet demonstrating how this library is meant to be used:
+
+```go
+func httpClient() (*http.Client, error)
+ tlsConfig := &tls.Config{}
+ err := rootcerts.ConfigureTLS(tlsConfig, &rootcerts.Config{
+ CAFile: os.Getenv("MYAPP_CAFILE"),
+ CAPath: os.Getenv("MYAPP_CAPATH"),
+ })
+ if err != nil {
+ return nil, err
+ }
+ c := cleanhttp.DefaultClient()
+ t := cleanhttp.DefaultTransport()
+ t.TLSClientConfig = tlsConfig
+ c.Transport = t
+ return c, nil
+}
+```

+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+ All distribution of Covered Software in Source Code Form, including any
+ Modifications that You create or to which You contribute, must be under
+ the terms of this License. You must inform recipients that the Source
+ Code Form of the Covered Software is governed by the terms of this
+ License, and how they can obtain a copy of this License. You may not
+ attempt to alter or restrict the recipients' rights in the Source Code
+ Form.
+
+3.2. Distribution of Executable Form
+
+ If You distribute Covered Software in Executable Form then:
+
+ a. such Covered Software must also be made available in Source Code Form,
+ as described in Section 3.1, and You must inform recipients of the
+ Executable Form how they can obtain a copy of such Source Code Form by
+ reasonable means in a timely manner, at a charge no more than the cost
+ of distribution to the recipient; and
+
+ b. You may distribute such Executable Form under the terms of this
+ License, or sublicense it under different terms, provided that the
+ license for the Executable Form does not attempt to limit or alter the
+ recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for
+ the Covered Software. If the Larger Work is a combination of Covered
+ Software with a work governed by one or more Secondary Licenses, and the
+ Covered Software is not Incompatible With Secondary Licenses, this
+ License permits You to additionally distribute such Covered Software
+ under the terms of such Secondary License(s), so that the recipient of
+ the Larger Work may, at their option, further distribute the Covered
+ Software under the terms of either this License or such Secondary
+ License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices
+ (including copyright notices, patent notices, disclaimers of warranty, or
+ limitations of liability) contained within the Source Code Form of the
+ Covered Software, except that You may alter any license notices to the
+ extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on
+ behalf of any Contributor. You must make it absolutely clear that any
+ such warranty, support, indemnity, or liability obligation is offered by
+ You alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute,
+ judicial order, or regulation then You must: (a) comply with the terms of
+ this License to the maximum extent possible; and (b) describe the
+ limitations and the code they affect. Such description must be placed in a
+ text file included with all distributions of the Covered Software under
+ this License. Except to the extent prohibited by statute or regulation,
+ such description must be sufficiently detailed for a recipient of ordinary
+ skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing
+ basis, if such Contributor fails to notify You of the non-compliance by
+ some reasonable means prior to 60 days after You have come back into
+ compliance. Moreover, Your grants from a particular Contributor are
+ reinstated on an ongoing basis if such Contributor notifies You of the
+ non-compliance by some reasonable means, this is the first time You have
+ received notice of non-compliance with this License from such
+ Contributor, and You become compliant prior to 30 days after Your receipt
+ of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions,
+ counter-claims, and cross-claims) alleging that a Contributor Version
+ directly or indirectly infringes any patent, then the rights granted to
+ You by any and all Contributors for the Covered Software under Section
+ 2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an "as is" basis,
+ without warranty of any kind, either expressed, implied, or statutory,
+ including, without limitation, warranties that the Covered Software is free
+ of defects, merchantable, fit for a particular purpose or non-infringing.
+ The entire risk as to the quality and performance of the Covered Software
+ is with You. Should any Covered Software prove defective in any respect,
+ You (not any Contributor) assume the cost of any necessary servicing,
+ repair, or correction. This disclaimer of warranty constitutes an essential
+ part of this License. No use of any Covered Software is authorized under
+ this License except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from
+ such party's negligence to the extent applicable law prohibits such
+ limitation. Some jurisdictions do not allow the exclusion or limitation of
+ incidental or consequential damages, so this exclusion and limitation may
+ not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts
+ of a jurisdiction where the defendant maintains its principal place of
+ business and such litigation shall be governed by laws of that
+ jurisdiction, without reference to its conflict-of-law provisions. Nothing
+ in this Section shall prevent a party's ability to bring cross-claims or
+ counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject
+ matter hereof. If any provision of this License is held to be
+ unenforceable, such provision shall be reformed only to the extent
+ necessary to make it enforceable. Any law or regulation which provides that
+ the language of a contract shall be construed against the drafter shall not
+ be used to construe this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+ Mozilla Foundation is the license steward. Except as provided in Section
+ 10.3, no one other than the license steward has the right to modify or
+ publish new versions of this License. Each version will be given a
+ distinguishing version number.
+
+10.2. Effect of New Versions
+
+ You may distribute the Covered Software under the terms of the version
+ of the License under which You originally received the Covered Software,
+ or under the terms of any subsequent version published by the license
+ steward.
+
+10.3. Modified Versions
+
+ If you create software not governed by this License, and you want to
+ create a new license for such software, you may create and use a
+ modified version of this License if you rename the license and remove
+ any references to the name of the license steward (except to note that
+ such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+ Licenses If You choose to distribute Source Code Form that is
+ Incompatible With Secondary Licenses under the terms of this version of

+ Each Contributor hereby grants You a world-wide, royalty-free,
+ non-exclusive license:
+
+ a. under intellectual property rights (other than patent or trademark)
+ Licensable by such Contributor to use, reproduce, make available,
+ modify, display, perform, distribute, and otherwise exploit its

+ effective for each Contribution on the date the Contributor first distributes
+ such Contribution.
+
+2.3. Limitations on Grant Scope
+
+ The licenses granted in this Section 2 are the only rights granted under this
+ License. No additional rights or licenses will be implied from the distribution
+ or licensing of Covered Software under this License. Notwithstanding Section
+ 2.1(b) above, no patent license is granted by a Contributor:
+
+ a. for any code that a Contributor has removed from Covered Software; or
+
+ b. for infringements caused by: (i) Your and any other third party’s
+ modifications of Covered Software, or (ii) the combination of its
+ Contributions with other software (except as part of its Contributor
+ Version); or
+
+ c. under Patent Claims infringed by Covered Software in the absence of its
+ Contributions.
+
+ This License does not grant any rights in the trademarks, service marks, or
+ logos of any Contributor (except as may be necessary to comply with the
+ notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+ No Contributor makes additional grants as a result of Your choice to
+ distribute the Covered Software under a subsequent version of this License
+ (see Section 10.2) or under the terms of a Secondary License (if permitted
+ under the terms of Section 3.3).
+
+2.5. Representation
+
+ Each Contributor represents that the Contributor believes its Contributions
+ are its original creation(s) or it has sufficient rights to grant the
+ rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+ This License is not intended to limit any rights You have under applicable
+ copyright doctrines of fair use, fair dealing, or other equivalents.
+
+2.7. Conditions
+
+ Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+ Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+ All distribution of Covered Software in Source Code Form, including any
+ Modifications that You create or to which You contribute, must be under the
+ terms of this License. You must inform recipients that the Source Code Form
+ of the Covered Software is governed by the terms of this License, and how
+ they can obtain a copy of this License. You may not attempt to alter or
+ restrict the recipients’ rights in the Source Code Form.
+
+3.2. Distribution of Executable Form
+
+ If You distribute Covered Software in Executable Form then:
+
+ a. such Covered Software must also be made available in Source Code Form,
+ as described in Section 3.1, and You must inform recipients of the
+ Executable Form how they can obtain a copy of such Source Code Form by
+ reasonable means in a timely manner, at a charge no more than the cost
+ of distribution to the recipient; and
+
+ b. You may distribute such Executable Form under the terms of this License,
+ or sublicense it under different terms, provided that the license for
+ the Executable Form does not attempt to limit or alter the recipients’
+ rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for the
+ Covered Software. If the Larger Work is a combination of Covered Software
+ with a work governed by one or more Secondary Licenses, and the Covered
+ Software is not Incompatible With Secondary Licenses, this License permits
+ You to additionally distribute such Covered Software under the terms of
+ such Secondary License(s), so that the recipient of the Larger Work may, at
+ their option, further distribute the Covered Software under the terms of
+ either this License or such Secondary License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices (including
+ copyright notices, patent notices, disclaimers of warranty, or limitations
+ of liability) contained within the Source Code Form of the Covered
+ Software, except that You may alter any license notices to the extent
+ required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on behalf
+ of any Contributor. You must make it absolutely clear that any such
+ warranty, support, indemnity, or liability obligation is offered by You
+ alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute, judicial
+ order, or regulation then You must: (a) comply with the terms of this License
+ to the maximum extent possible; and (b) describe the limitations and the code
+ they affect. Such description must be placed in a text file included with all
+ distributions of the Covered Software under this License. Except to the
+ extent prohibited by statute or regulation, such description must be
+ sufficiently detailed for a recipient of ordinary skill to be able to
+ understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing basis,
+ if such Contributor fails to notify You of the non-compliance by some
+ reasonable means prior to 60 days after You have come back into compliance.
+ Moreover, Your grants from a particular Contributor are reinstated on an
+ ongoing basis if such Contributor notifies You of the non-compliance by
+ some reasonable means, this is the first time You have received notice of
+ non-compliance with this License from such Contributor, and You become
+ compliant prior to 30 days after Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions, counter-claims,
+ and cross-claims) alleging that a Contributor Version directly or
+ indirectly infringes any patent, then the rights granted to You by any and
+ all Contributors for the Covered Software under Section 2.1 of this License
+ shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an “as is” basis, without
+ warranty of any kind, either expressed, implied, or statutory, including,
+ without limitation, warranties that the Covered Software is free of defects,
+ merchantable, fit for a particular purpose or non-infringing. The entire
+ risk as to the quality and performance of the Covered Software is with You.
+ Should any Covered Software prove defective in any respect, You (not any
+ Contributor) assume the cost of any necessary servicing, repair, or
+ correction. This disclaimer of warranty constitutes an essential part of this
+ License. No use of any Covered Software is authorized under this License
+ except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from such
+ party’s negligence to the extent applicable law prohibits such limitation.
+ Some jurisdictions do not allow the exclusion or limitation of incidental or
+ consequential damages, so this exclusion and limitation may not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts of
+ a jurisdiction where the defendant maintains its principal place of business
+ and such litigation shall be governed by laws of that jurisdiction, without
+ reference to its conflict-of-law provisions. Nothing in this Section shall
+ prevent a party’s ability to bring cross-claims or counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject matter
+ hereof. If any provision of this License is held to be unenforceable, such
+ provision shall be reformed only to the extent necessary to make it
+ enforceable. Any law or regulation which provides that the language of a
+ contract shall be construed against the drafter shall not be used to construe
+ this License against a Contributor.
+
+

+# go-homedir
+
+This is a Go library for detecting the user's home directory without
+the use of cgo, so the library can be used in cross-compilation environments.
+
+Usage is incredibly simple, just call `homedir.Dir()` to get the home directory
+for a user, and `homedir.Expand()` to expand the `~` in a path to the home
+directory.
+
+**Why not just use `os/user`?** The built-in `os/user` package requires
+cgo on Darwin systems. This means that any Go code that uses that package
+cannot cross compile. But 99% of the time the use for `os/user` is just to
+retrieve the home directory, which we can do for the current user without
+cgo. This library does that, enabling cross-compilation.

+# mapstructure [](https://godoc.org/github.com/mitchellh/mapstructure)
+
+mapstructure is a Go library for decoding generic map values to structures
+and vice versa, while providing helpful error handling.
+
+This library is most useful when decoding values from some data stream (JSON,
+Gob, etc.) where you don't _quite_ know the structure of the underlying data
+until you read a part of it. You can therefore read a `map[string]interface{}`
+and use this library to decode it into the proper underlying native Go
+structure.
+
+## Installation
+
+Standard `go get`:
+
+```
+$ go get github.com/mitchellh/mapstructure
+```
+
+## Usage & Example
+
+For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/mapstructure).
+
+The `Decode` function has examples associated with it there.
+
+## But Why?!
+
+Go offers fantastic standard libraries for decoding formats such as JSON.
+The standard method is to have a struct pre-created, and populate that struct
+from the bytes of the encoded format. This is great, but the problem is if
+you have configuration or an encoding that changes slightly depending on
+specific fields. For example, consider this JSON:
+
+```json
+{
+ "type": "person",
+ "name": "Mitchell"
+}
+```
+
+Perhaps we can't populate a specific structure without first reading
+the "type" field from the JSON. We could always do two passes over the
+decoding of the JSON (reading the "type" first, and the rest later).
+However, it is much simpler to just decode this into a `map[string]interface{}`
+structure, read the "type" key, then use something like this library
+to decode it into the proper structure.

+# etcd/clientv3
+
+[](https://etcd.io/docs)
+[](https://godoc.org/go.etcd.io/etcd/clientv3)
+
+`etcd/clientv3` is the official Go etcd client for v3.
+
+## Install
+
+```bash
+go get go.etcd.io/etcd/clientv3
+```
+
+## Get started
+
+Create client using `clientv3.New`:
+
+```go
+cli, err := clientv3.New(clientv3.Config{
+ Endpoints: []string{"localhost:2379", "localhost:22379", "localhost:32379"},
+ DialTimeout: 5 * time.Second,
+})
+if err != nil {
+ // handle error!
+}
+defer cli.Close()
+```
+
+etcd v3 uses [`gRPC`](https://www.grpc.io) for remote procedure calls. And `clientv3` uses
+[`grpc-go`](https://github.com/grpc/grpc-go) to connect to etcd. Make sure to close the client after using it.
+If the client is not closed, the connection will have leaky goroutines. To specify client request timeout,
+pass `context.WithTimeout` to APIs:
+
+```go
+ctx, cancel := context.WithTimeout(context.Background(), timeout)
+resp, err := cli.Put(ctx, "sample_key", "sample_value")
+cancel()
+if err != nil {
+ // handle error!
+}
+// use the response
+```
+
+For full compatibility, it is recommended to vendor builds using etcd's vendored packages, using tools like `golang/dep`, as in [vendor directories](https://golang.org/cmd/go/#hdr-Vendor_Directories).
+
+## Error Handling
+
+etcd client returns 2 types of errors:
+
+1. context error: canceled or deadline exceeded.
+2. gRPC error: see [api/v3rpc/rpctypes](https://godoc.org/go.etcd.io/etcd/etcdserver/api/v3rpc/rpctypes).
+
+Here is the example code to handle client errors:
+
+```go
+resp, err := cli.Put(ctx, "", "")
+if err != nil {
+ switch err {
+ case context.Canceled:
+ log.Fatalf("ctx is canceled by another routine: %v", err)
+ case context.DeadlineExceeded:
+ log.Fatalf("ctx is attached with a deadline is exceeded: %v", err)
+ case rpctypes.ErrEmptyKey:
+ log.Fatalf("client-side error: %v", err)
+ default:
+ log.Fatalf("bad cluster endpoints, which are not etcd servers: %v", err)
+ }
+}
+```
+
+## Metrics
+
+The etcd client optionally exposes RPC metrics through [go-grpc-prometheus](https://github.com/grpc-ecosystem/go-grpc-prometheus). See the [examples](https://github.com/etcd-io/etcd/blob/master/clientv3/example_metrics_test.go).
+
+## Namespacing
+
+The [namespace](https://godoc.org/go.etcd.io/etcd/clientv3/namespace) package provides `clientv3` interface wrappers to transparently isolate client requests to a user-defined prefix.
+
+## Request size limit
+
+Client request size limit is configurable via `clientv3.Config.MaxCallSendMsgSize` and `MaxCallRecvMsgSize` in bytes. If none given, client request send limit defaults to 2 MiB including gRPC overhead bytes. And receive limit defaults to `math.MaxInt32`.
+
+## Examples
+
+More code examples can be found at [GoDoc](https://godoc.org/go.etcd.io/etcd/clientv3).

+// and consists of three components:
+// 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check
+// for the absence or presence of a value, or compare with a given value. Two different tests in the guard
+// may apply to the same or different entries in the database. All tests in the guard are applied and
+// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
+// it executes f op (see item 3 below).
+// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
+// lookup operation, and applies to a single database entry. Two different operations in the list may apply
+// to the same or different entries in the database. These operations are executed
+// if guard evaluates to
+// true.
+// 3. A list of database operations called f op. Like t op, but executed if guard evaluates to false.

+// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
+// it executes f op (see item 3 below).
+// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
+// lookup operation, and applies to a single database entry. Two different operations in the list may apply
+// to the same or different entries in the database. These operations are executed

+# Raft library
+
+Raft is a protocol with which a cluster of nodes can maintain a replicated state machine.
+The state machine is kept in sync through the use of a replicated log.
+For more details on Raft, see "In Search of an Understandable Consensus Algorithm"
+(https://raft.github.io/raft.pdf) by Diego Ongaro and John Ousterhout.
+
+This Raft library is stable and feature complete. As of 2016, it is **the most widely used** Raft library in production, serving tens of thousands clusters each day. It powers distributed systems such as etcd, Kubernetes, Docker Swarm, Cloud Foundry Diego, CockroachDB, TiDB, Project Calico, Flannel, and more.
+
+Most Raft implementations have a monolithic design, including storage handling, messaging serialization, and network transport. This library instead follows a minimalistic design philosophy by only implementing the core raft algorithm. This minimalism buys flexibility, determinism, and performance.
+
+To keep the codebase small as well as provide flexibility, the library only implements the Raft algorithm; both network and disk IO are left to the user. Library users must implement their own transportation layer for message passing between Raft peers over the wire. Similarly, users must implement their own storage layer to persist the Raft log and state.
+
+In order to easily test the Raft library, its behavior should be deterministic. To achieve this determinism, the library models Raft as a state machine. The state machine takes a `Message` as input. A message can either be a local timer update or a network message sent from a remote peer. The state machine's output is a 3-tuple `{[]Messages, []LogEntries, NextState}` consisting of an array of `Messages`, `log entries`, and `Raft state changes`. For state machines with the same state, the same state machine input should always generate the same state machine output.
+
+A simple example application, _raftexample_, is also available to help illustrate how to use this package in practice: https://github.com/etcd-io/etcd/tree/master/contrib/raftexample
+
+# Features
+
+This raft implementation is a full feature implementation of Raft protocol. Features includes:
+
+- Leader election
+- Log replication
+- Log compaction
+- Membership changes
+- Leadership transfer extension
+- Efficient linearizable read-only queries served by both the leader and followers
+ - leader checks with quorum and bypasses Raft log before processing read-only queries
+ - followers asks leader to get a safe read index before processing read-only queries
+- More efficient lease-based linearizable read-only queries served by both the leader and followers
+ - leader bypasses Raft log and processing read-only queries locally
+ - followers asks leader to get a safe read index before processing read-only queries
+ - this approach relies on the clock of the all the machines in raft group
+
+This raft implementation also includes a few optional enhancements:
+
+- Optimistic pipelining to reduce log replication latency
+- Flow control for log replication
+- Batching Raft messages to reduce synchronized network I/O calls
+- Batching log entries to reduce disk synchronized I/O
+- Writing to leader's disk in parallel
+- Internal proposal redirection from followers to leader
+- Automatic stepping down when the leader loses quorum
+- Protection against unbounded log growth when quorum is lost

+
+## Usage
+
+The primary object in raft is a Node. Either start a Node from scratch using raft.StartNode or start a Node from some initial state using raft.RestartNode.
+
+To start a three-node cluster
+```go
+ storage := raft.NewMemoryStorage()
+ c := &Config{
+ ID: 0x01,
+ ElectionTick: 10,
+ HeartbeatTick: 1,
+ Storage: storage,
+ MaxSizePerMsg: 4096,
+ MaxInflightMsgs: 256,
+ }
+ // Set peer list to the other nodes in the cluster.
+ // Note that they need to be started separately as well.
+ n := raft.StartNode(c, []raft.Peer{{ID: 0x02}, {ID: 0x03}})
+```
+
+Start a single node cluster, like so:
+```go
+ // Create storage and config as shown above.
+ // Set peer list to itself, so this node can become the leader of this single-node cluster.
+ peers := []raft.Peer{{ID: 0x01}}
+ n := raft.StartNode(c, peers)
+```
+
+To allow a new node to join this cluster, do not pass in any peers. First, add the node to the existing cluster by calling `ProposeConfChange` on any existing node inside the cluster. Then, start the node with an empty peer list, like so:
+```go
+ // Create storage and config as shown above.
+ n := raft.StartNode(c, nil)
+```
+
+To restart a node from previous state:
+```go
+ storage := raft.NewMemoryStorage()
+
+ // Recover the in-memory storage from persistent snapshot, state and entries.
+ storage.ApplySnapshot(snapshot)
+ storage.SetHardState(state)
+ storage.Append(entries)
+
+ c := &Config{
+ ID: 0x01,
+ ElectionTick: 10,
+ HeartbeatTick: 1,
+ Storage: storage,
+ MaxSizePerMsg: 4096,
+ MaxInflightMsgs: 256,
+ }
+
+ // Restart raft without peer information.
+ // Peer information is already included in the storage.
+ n := raft.RestartNode(c)
+```
+
+After creating a Node, the user has a few responsibilities:
+
+First, read from the Node.Ready() channel and process the updates it contains. These steps may be performed in parallel, except as noted in step 2.
+
+1. Write Entries, HardState and Snapshot to persistent storage in order, i.e. Entries first, then HardState and Snapshot if they are not empty. If persistent storage supports atomic writes then all of them can be written together. Note that when writing an Entry with Index i, any previously-persisted entries with Index >= i must be discarded.
+
+2. Send all Messages to the nodes named in the To field. It is important that no messages be sent until the latest HardState has been persisted to disk, and all Entries written by any previous Ready batch (Messages may be sent while entries from the same batch are being persisted). To reduce the I/O latency, an optimization can be applied to make leader write to disk in parallel with its followers (as explained at section 10.2.1 in Raft thesis). If any Message has type MsgSnap, call Node.ReportSnapshot() after it has been sent (these messages may be large). Note: Marshalling messages is not thread-safe; it is important to make sure that no new entries are persisted while marshalling. The easiest way to achieve this is to serialise the messages directly inside the main raft loop.
+
+3. Apply Snapshot (if any) and CommittedEntries to the state machine. If any committed Entry has Type EntryConfChange, call Node.ApplyConfChange() to apply it to the node. The configuration change may be cancelled at this point by setting the NodeID field to zero before calling ApplyConfChange (but ApplyConfChange must be called one way or the other, and the decision to cancel must be based solely on the state machine and not external information such as the observed health of the node).
+
+4. Call Node.Advance() to signal readiness for the next batch of updates. This may be done at any time after step 1, although all updates must be processed in the order they were returned by Ready.
+
+Second, all persisted log entries must be made available via an implementation of the Storage interface. The provided MemoryStorage type can be used for this (if repopulating its state upon a restart), or a custom disk-backed implementation can be supplied.
+
+Third, after receiving a message from another node, pass it to Node.Step:
+
+```go
+ func recvRaftRPC(ctx context.Context, m raftpb.Message) {
+ n.Step(ctx, m)
+ }
+```
+
+Finally, call `Node.Tick()` at regular intervals (probably via a `time.Ticker`). Raft has two important timeouts: heartbeat and the election timeout. However, internally to the raft package time is represented by an abstract "tick".
+
+The total state machine handling loop will look something like this:
+
+```go
+ for {
+ select {
+ case <-s.Ticker:
+ n.Tick()
+ case rd := <-s.Node.Ready():
+ saveToStorage(rd.HardState, rd.Entries, rd.Snapshot)
+ send(rd.Messages)
+ if !raft.IsEmptySnap(rd.Snapshot) {
+ processSnapshot(rd.Snapshot)
+ }
+ for _, entry := range rd.CommittedEntries {
+ process(entry)
+ if entry.Type == raftpb.EntryConfChange {
+ var cc raftpb.ConfChange
+ cc.Unmarshal(entry.Data)
+ s.Node.ApplyConfChange(cc)
+ }
+ }
+ s.Node.Advance()
+ case <-s.done:
+ return
+ }
+ }
+```
+
+To propose changes to the state machine from the node to take application data, serialize it into a byte slice and call:
+
+```go
+ n.Propose(ctx, data)
+```
+
+If the proposal is committed, data will appear in committed entries with type raftpb.EntryNormal. There is no guarantee that a proposed command will be committed; the command may have to be reproposed after a timeout.
+
+To add or remove node in a cluster, build ConfChange struct 'cc' and call:
+
+```go
+ n.ProposeConfChange(ctx, cc)
+```
+
+After config change is committed, some committed entry with type raftpb.EntryConfChange will be returned. This must be applied to node through:
+
+```go
+ var cc raftpb.ConfChange
+ cc.Unmarshal(data)
+ n.ApplyConfChange(cc)
+```
+
+Note: An ID represents a unique node in a cluster for all time. A
+given ID MUST be used only once even if the old node has been removed.
+This means that for example IP addresses make poor node IDs since they
+may be reused. Node IDs must be non-zero.
+
+## Implementation notes
+
+This implementation is up to date with the final Raft thesis (https://github.com/ongardie/dissertation/blob/master/stanford.pdf), although this implementation of the membership change protocol differs somewhat from that described in chapter 4. The key invariant that membership changes happen one node at a time is preserved, but in our implementation the membership change takes effect when its entry is applied, not when it is added to the log (so the entry is committed under the old membership instead of the new). This is equivalent in terms of safety, since the old and new configurations are guaranteed to overlap.
+
+To ensure there is no attempt to commit two membership changes at once by matching log positions (which would be unsafe since they should have different quorum requirements), any proposed membership change is simply disallowed while any uncommitted change appears in the leader's log.
+
+This approach introduces a problem when removing a member from a two-member cluster: If one of the members dies before the other one receives the commit of the confchange entry, then the member cannot be removed any more since the cluster cannot make progress. For this reason it is highly recommended to use three or more nodes in every cluster.

+## Progress
+
+Progress represents a follower’s progress in the view of the leader. Leader maintains progresses of all followers, and sends `replication message` to the follower based on its progress.
+
+`replication message` is a `msgApp` with log entries.
+
+A progress has two attribute: `match` and `next`. `match` is the index of the highest known matched entry. If leader knows nothing about follower’s replication status, `match` is set to zero. `next` is the index of the first entry that will be replicated to the follower. Leader puts entries from `next` to its latest one in next `replication message`.
+
+A progress is in one of the three state: `probe`, `replicate`, `snapshot`.
+
+```
+ +--------------------------------------------------------+
+ | send snapshot |
+ | |
+ +---------+----------+ +----------v---------+
+ +---> probe | | snapshot |
+ | | max inflight = 1 <----------------------------------+ max inflight = 0 |
+ | +---------+----------+ +--------------------+
+ | | 1. snapshot success
+ | | (next=snapshot.index + 1)
+ | | 2. snapshot failure
+ | | (no change)
+ | | 3. receives msgAppResp(rej=false&&index>lastsnap.index)
+ | | (match=m.index,next=match+1)
+receives msgAppResp(rej=true)
+(next=match+1)| |
+ | |
+ | |
+ | | receives msgAppResp(rej=false&&index>match)
+ | | (match=m.index,next=match+1)
+ | |
+ | |
+ | |
+ | +---------v----------+
+ | | replicate |
+ +---+ max inflight = n |
+ +--------------------+
+```
+
+When the progress of a follower is in `probe` state, leader sends at most one `replication message` per heartbeat interval. The leader sends `replication message` slowly and probing the actual progress of the follower. A `msgHeartbeatResp` or a `msgAppResp` with reject might trigger the sending of the next `replication message`.
+
+When the progress of a follower is in `replicate` state, leader sends `replication message`, then optimistically increases `next` to the latest entry sent. This is an optimized state for fast replicating log entries to the follower.
+
+When the progress of a follower is in `snapshot` state, leader stops sending any `replication message`.
+
+A newly elected leader sets the progresses of all the followers to `probe` state with `match` = 0 and `next` = last index. The leader slowly (at most once per heartbeat) sends `replication message` to the follower and probes its progress.
+
+A progress changes to `replicate` when the follower replies with a non-rejection `msgAppResp`, which implies that it has matched the index sent. At this point, leader starts to stream log entries to the follower fast. The progress will fall back to `probe` when the follower replies a rejection `msgAppResp` or the link layer reports the follower is unreachable. We aggressively reset `next` to `match`+1 since if we receive any `msgAppResp` soon, both `match` and `next` will increase directly to the `index` in `msgAppResp`. (We might end up with sending some duplicate entries when aggressively reset `next` too low. see open question)
+
+A progress changes from `probe` to `snapshot` when the follower falls very far behind and requires a snapshot. After sending `msgSnap`, the leader waits until the success, failure or abortion of the previous snapshot sent. The progress will go back to `probe` after the sending result is applied.
+
+### Flow Control
+
+1. limit the max size of message sent per message. Max should be configurable.
+Lower the cost at probing state as we limit the size per message; lower the penalty when aggressively decreased to a too low `next`
+
+2. limit the # of in flight messages < N when in `replicate` state. N should be configurable. Most implementation will have a sending buffer on top of its actual network transport layer (not blocking raft node). We want to make sure raft does not overflow that buffer, which can cause message dropping and triggering a bunch of unnecessary resending repeatedly.

+Package raft sends and receives messages in the Protocol Buffer format
+defined in the raftpb package.
+
+Raft is a protocol with which a cluster of nodes can maintain a replicated state machine.
+The state machine is kept in sync through the use of a replicated log.
+For more details on Raft, see "In Search of an Understandable Consensus Algorithm"
+(https://raft.github.io/raft.pdf) by Diego Ongaro and John Ousterhout.
+
+A simple example application, _raftexample_, is also available to help illustrate
+how to use this package in practice:
+https://github.com/etcd-io/etcd/tree/master/contrib/raftexample
+
+Usage
+
+The primary object in raft is a Node. You either start a Node from scratch
+using raft.StartNode or start a Node from some initial state using raft.RestartNode.
+
+To start a node from scratch:
+
+ storage := raft.NewMemoryStorage()
+ c := &Config{
+ ID: 0x01,
+ ElectionTick: 10,
+ HeartbeatTick: 1,
+ Storage: storage,
+ MaxSizePerMsg: 4096,
+ MaxInflightMsgs: 256,
+ }
+ n := raft.StartNode(c, []raft.Peer{{ID: 0x02}, {ID: 0x03}})
+
+To restart a node from previous state:
+
+ storage := raft.NewMemoryStorage()
+
+ // recover the in-memory storage from persistent
+ // snapshot, state and entries.
+ storage.ApplySnapshot(snapshot)
+ storage.SetHardState(state)
+ storage.Append(entries)
+
+ c := &Config{
+ ID: 0x01,
+ ElectionTick: 10,
+ HeartbeatTick: 1,
+ Storage: storage,
+ MaxSizePerMsg: 4096,
+ MaxInflightMsgs: 256,
+ }
+
+ // restart raft without peer information.
+ // peer information is already included in the storage.
+ n := raft.RestartNode(c)
+
+Now that you are holding onto a Node you have a few responsibilities:
+
+First, you must read from the Node.Ready() channel and process the updates
+it contains. These steps may be performed in parallel, except as noted in step
+2.
+
+1. Write HardState, Entries, and Snapshot to persistent storage if they are
+not empty. Note that when writing an Entry with Index i, any
+previously-persisted entries with Index >= i must be discarded.
+
+2. Send all Messages to the nodes named in the To field. It is important that
+no messages be sent until the latest HardState has been persisted to disk,
+and all Entries written by any previous Ready batch (Messages may be sent while
+entries from the same batch are being persisted). To reduce the I/O latency, an
+optimization can be applied to make leader write to disk in parallel with its
+followers (as explained at section 10.2.1 in Raft thesis). If any Message has type
+MsgSnap, call Node.ReportSnapshot() after it has been sent (these messages may be
+large).
+
+Note: Marshalling messages is not thread-safe; it is important that you
+make sure that no new entries are persisted while marshalling.
+The easiest way to achieve this is to serialize the messages directly inside
+your main raft loop.
+
+3. Apply Snapshot (if any) and CommittedEntries to the state machine.
+If any committed Entry has Type EntryConfChange, call Node.ApplyConfChange()
+to apply it to the node. The configuration change may be cancelled at this point
+by setting the NodeID field to zero before calling ApplyConfChange
+(but ApplyConfChange must be called one way or the other, and the decision to cancel
+must be based solely on the state machine and not external information such as
+the observed health of the node).
+
+4. Call Node.Advance() to signal readiness for the next batch of updates.
+This may be done at any time after step 1, although all updates must be processed
+in the order they were returned by Ready.
+
+Second, all persisted log entries must be made available via an
+implementation of the Storage interface. The provided MemoryStorage
+type can be used for this (if you repopulate its state upon a
+restart), or you can supply your own disk-backed implementation.
+
+Third, when you receive a message from another node, pass it to Node.Step:
+
+ func recvRaftRPC(ctx context.Context, m raftpb.Message) {
+ n.Step(ctx, m)
+ }
+
+Finally, you need to call Node.Tick() at regular intervals (probably
+via a time.Ticker). Raft has two important timeouts: heartbeat and the
+election timeout. However, internally to the raft package time is
+represented by an abstract "tick".
+
+The total state machine handling loop will look something like this:
+
+ for {
+ select {
+ case <-s.Ticker:
+ n.Tick()
+ case rd := <-s.Node.Ready():
+ saveToStorage(rd.State, rd.Entries, rd.Snapshot)
+ send(rd.Messages)
+ if !raft.IsEmptySnap(rd.Snapshot) {
+ processSnapshot(rd.Snapshot)
+ }
+ for _, entry := range rd.CommittedEntries {
+ process(entry)
+ if entry.Type == raftpb.EntryConfChange {
+ var cc raftpb.ConfChange
+ cc.Unmarshal(entry.Data)
+ s.Node.ApplyConfChange(cc)
+ }
+ }
+ s.Node.Advance()
+ case <-s.done:
+ return
+ }
+ }
+
+To propose changes to the state machine from your node take your application
+data, serialize it into a byte slice and call:
+
+ n.Propose(ctx, data)
+
+If the proposal is committed, data will appear in committed entries with type
+raftpb.EntryNormal. There is no guarantee that a proposed command will be
+committed; you may have to re-propose after a timeout.
+
+To add or remove a node in a cluster, build ConfChange struct 'cc' and call:
+
+ n.ProposeConfChange(ctx, cc)
+
+After config change is committed, some committed entry with type
+raftpb.EntryConfChange will be returned. You must apply it to node through:
+
+ var cc raftpb.ConfChange
+ cc.Unmarshal(data)
+ n.ApplyConfChange(cc)
+
+Note: An ID represents a unique node in a cluster for all time. A
+given ID MUST be used only once even if the old node has been removed.
+This means that for example IP addresses make poor node IDs since they
+may be reused. Node IDs must be non-zero.
+
+Implementation notes
+
+This implementation is up to date with the final Raft thesis
+(https://github.com/ongardie/dissertation/blob/master/stanford.pdf), although our
+implementation of the membership change protocol differs somewhat from
+that described in chapter 4. The key invariant that membership changes
+happen one node at a time is preserved, but in our implementation the
+membership change takes effect when its entry is applied, not when it
+is added to the log (so the entry is committed under the old
+membership instead of the new). This is equivalent in terms of safety,
+since the old and new configurations are guaranteed to overlap.
+
+To ensure that we do not attempt to commit two membership changes at
+once by matching log positions (which would be unsafe since they
+should have different quorum requirements), we simply disallow any
+proposed membership change while any uncommitted change appears in
+the leader's log.
+
+This approach introduces a problem when you try to remove a member
+from a two-member cluster: If one of the members dies before the
+other one receives the commit of the confchange entry, then the member
+cannot be removed any more since the cluster cannot make progress.
+For this reason it is highly recommended to use three or more nodes in
+every cluster.
+
+MessageType
+
+Package raft sends and receives message in Protocol Buffer format (defined
+in raftpb package). Each state (follower, candidate, leader) implements its
+own 'step' method ('stepFollower', 'stepCandidate', 'stepLeader') when
+advancing with the given raftpb.Message. Each step is determined by its
+raftpb.MessageType. Note that every step is checked by one common method
+'Step' that safety-checks the terms of node and incoming message to prevent
+stale log entries:
+
+ 'MsgHup' is used for election. If a node is a follower or candidate, the
+ 'tick' function in 'raft' struct is set as 'tickElection'. If a follower or
+ candidate has not received any heartbeat before the election timeout, it
+ passes 'MsgHup' to its Step method and becomes (or remains) a candidate to
+ start a new election.
+
+ 'MsgBeat' is an internal type that signals the leader to send a heartbeat of
+ the 'MsgHeartbeat' type. If a node is a leader, the 'tick' function in
+ the 'raft' struct is set as 'tickHeartbeat', and triggers the leader to
+ send periodic 'MsgHeartbeat' messages to its followers.
+
+ 'MsgProp' proposes to append data to its log entries. This is a special
+ type to redirect proposals to leader. Therefore, send method overwrites
+ raftpb.Message's term with its HardState's term to avoid attaching its
+ local term to 'MsgProp'. When 'MsgProp' is passed to the leader's 'Step'
+ method, the leader first calls the 'appendEntry' method to append entries
+ to its log, and then calls 'bcastAppend' method to send those entries to
+ its peers. When passed to candidate, 'MsgProp' is dropped. When passed to
+ follower, 'MsgProp' is stored in follower's mailbox(msgs) by the send
+ method. It is stored with sender's ID and later forwarded to leader by
+ rafthttp package.
+
+ 'MsgApp' contains log entries to replicate. A leader calls bcastAppend,
+ which calls sendAppend, which sends soon-to-be-replicated logs in 'MsgApp'
+ type. When 'MsgApp' is passed to candidate's Step method, candidate reverts
+ back to follower, because it indicates that there is a valid leader sending
+ 'MsgApp' messages. Candidate and follower respond to this message in
+ 'MsgAppResp' type.
+
+ 'MsgAppResp' is response to log replication request('MsgApp'). When
+ 'MsgApp' is passed to candidate or follower's Step method, it responds by
+ calling 'handleAppendEntries' method, which sends 'MsgAppResp' to raft
+ mailbox.
+
+ 'MsgVote' requests votes for election. When a node is a follower or
+ candidate and 'MsgHup' is passed to its Step method, then the node calls
+ 'campaign' method to campaign itself to become a leader. Once 'campaign'
+ method is called, the node becomes candidate and sends 'MsgVote' to peers
+ in cluster to request votes. When passed to leader or candidate's Step
+ method and the message's Term is lower than leader's or candidate's,
+ 'MsgVote' will be rejected ('MsgVoteResp' is returned with Reject true).
+ If leader or candidate receives 'MsgVote' with higher term, it will revert
+ back to follower. When 'MsgVote' is passed to follower, it votes for the
+ sender only when sender's last term is greater than MsgVote's term or
+ sender's last term is equal to MsgVote's term but sender's last committed
+ index is greater than or equal to follower's.
+
+ 'MsgVoteResp' contains responses from voting request. When 'MsgVoteResp' is
+ passed to candidate, the candidate calculates how many votes it has won. If
+ it's more than majority (quorum), it becomes leader and calls 'bcastAppend'.
+ If candidate receives majority of votes of denials, it reverts back to
+ follower.
+
+ 'MsgPreVote' and 'MsgPreVoteResp' are used in an optional two-phase election
+ protocol. When Config.PreVote is true, a pre-election is carried out first
+ (using the same rules as a regular election), and no node increases its term
+ number unless the pre-election indicates that the campaigning node would win.
+ This minimizes disruption when a partitioned node rejoins the cluster.
+
+ 'MsgSnap' requests to install a snapshot message. When a node has just
+ become a leader or the leader receives 'MsgProp' message, it calls
+ 'bcastAppend' method, which then calls 'sendAppend' method to each
+ follower. In 'sendAppend', if a leader fails to get term or entries,
+ the leader requests snapshot by sending 'MsgSnap' type message.
+
+ 'MsgSnapStatus' tells the result of snapshot install message. When a
+ follower rejected 'MsgSnap', it indicates the snapshot request with
+ 'MsgSnap' had failed from network issues which causes the network layer
+ to fail to send out snapshots to its followers. Then leader considers
+ follower's progress as probe. When 'MsgSnap' were not rejected, it
+ indicates that the snapshot succeeded and the leader sets follower's
+ progress to probe and resumes its log replication.
+
+ 'MsgHeartbeat' sends heartbeat from leader. When 'MsgHeartbeat' is passed
+ to candidate and message's term is higher than candidate's, the candidate
+ reverts back to follower and updates its committed index from the one in
+ this heartbeat. And it sends the message to its mailbox. When
+ 'MsgHeartbeat' is passed to follower's Step method and message's term is
+ higher than follower's, the follower updates its leaderID with the ID
+ from the message.
+
+ 'MsgHeartbeatResp' is a response to 'MsgHeartbeat'. When 'MsgHeartbeatResp'
+ is passed to leader's Step method, the leader knows which follower
+ responded. And only when the leader's last committed index is greater than
+ follower's Match index, the leader runs 'sendAppend` method.
+
+ 'MsgUnreachable' tells that request(message) wasn't delivered. When
+ 'MsgUnreachable' is passed to leader's Step method, the leader discovers
+ that the follower that sent this 'MsgUnreachable' is not reachable, often
+ indicating 'MsgApp' is lost. When follower's progress state is replicate,
+ the leader sets it back to probe.

+// attach an action on the state machine to the application of the config change
+// proposal. Note that contrary to Joint Consensus as outlined in the Raft
+// paper[1], configuration changes become active when they are *applied* to the
+// state machine (not when they are appended to the log).
+//
+// The simple protocol can be used whenever only a single change is made.
+//
+// Non-simple changes require the use of Joint Consensus, for which two
+// configuration changes are run. The first configuration change specifies the
+// desired changes and transitions the Raft group into the joint configuration,
+// in which quorum requires a majority of both the pre-changes and post-changes
+// configuration. Joint Consensus avoids entering fragile intermediate
+// configurations that could compromise survivability. For example, without the

+// replication factor of three, it is not possible to replace a voter without
+// entering an intermediate configuration that does not survive the outage of
+// one availability zone.

+// is used, and assigns the task of leaving the joint configuration either to
