VOL-1497 : Add more control to kv/memory access

- Added kv locking mechanism (etcd only)
- (watch) control path access whenever possible
- (watch) use a transaction for updates and merge with memory
- cleaned up vendoring
- misc changes to fix exceptions found along the way

Amendments:

- Copyright header got removed in auto-generated file
- Changed default locking to false for KV list operation
- Updated backend api to allow the passing of locking parameter

 Sinks

 The `metrics` package makes use of a `MetricSink` interface to support delivery
 to any type of backend. Currently the following sinks are provided:

 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:
 
-    func SlowMethod() {
-        // Profiling the runtime of a method
-        defer metrics.MeasureSince([]string{"SlowMethod"}, time.Now())
-    }
+```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)
+// Configure a statsite sink as the global metrics sink
+sink, _ := metrics.NewStatsiteSink("statsite:8125")

-    metrics.EmitKey([]string{"questions", "meaning of life"}, 42)
+// Emit a Key/Value pair

+# 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.
+

+
+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.

+go-immutable-radix [![Build Status](https://travis-ci.org/hashicorp/go-immutable-radix.png)](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")
+}
+```

+
+     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.
+
+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.
+

+# 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://ramcloud.stanford.edu/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

+## 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`.

+
+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://ramcloud.stanford.edu/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://ramcloud.stanford.edu/~ongaro/thesis.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.

-## App Engine
-
-In change 96e89be (March 2015), we removed the `oauth2.Context2` type in favor
-of the [`context.Context`](https://golang.org/x/net/context#Context) type from
-the `golang.org/x/net/context` package. Later replaced by the standard `context` package
-of the [`context.Context`](https://golang.org/pkg/context#Context) type.
-
-
-This means it's no longer possible to use the "Classic App Engine"
-`appengine.Context` type with the `oauth2` package. (You're using
-Classic App Engine if you import the package `"appengine"`.)
-
-To work around this, you may use the new `"google.golang.org/appengine"`
-package. This package has almost the same API as the `"appengine"` package,
-but it can be fetched with `go get` and used on "Managed VMs" and well as
-Classic App Engine.
-
-See the [new `appengine` package's readme](https://github.com/golang/appengine#updating-a-go-app-engine-app)
-for information on updating your app.
-
-If you don't want to update your entire app to use the new App Engine packages,
-you may use both sets of packages in parallel, using only the new packages
-with the `oauth2` package.
-
-```go
-import (
-	"context"
-	"golang.org/x/oauth2"
-	"golang.org/x/oauth2/google"
-	newappengine "google.golang.org/appengine"
-	newurlfetch "google.golang.org/appengine/urlfetch"

-// `HttpRule` defines the mapping of an RPC method to one or more HTTP
-// REST API methods. The mapping specifies how different portions of the RPC
-// request message are mapped to URL path, URL query parameters, and
-// HTTP request body. The mapping is typically specified as an
-// `google.api.http` annotation on the RPC method,
-// see "google/api/annotations.proto" for details.
-//
-// The mapping consists of a field specifying the path template and
-// method kind.  The path template can refer to fields in the request
-// message, as in the example below which describes a REST GET
-// operation on a resource collection of messages:
-//
-//
-//     service Messaging {
-//       rpc GetMessage(GetMessageRequest) returns (Message) {
-//         option (google.api.http).get = "/v1/messages/{message_id}/{sub.subfield}";
-//       }
-//     }
-//     message GetMessageRequest {
-//       message SubMessage {
-//         string subfield = 1;
-//       }
-//       string message_id = 1; // mapped to the URL
-//       SubMessage sub = 2;    // `sub.subfield` is url-mapped
-//     }
-//     message Message {
-//       string text = 1; // content of the resource
-//     }
-//
-// The same http annotation can alternatively be expressed inside the
-// `GRPC API Configuration` YAML file.
-//
-//     http:
-//       rules:
-//         - selector: <proto_package_name>.Messaging.GetMessage
-//           get: /v1/messages/{message_id}/{sub.subfield}
-//
-// This definition enables an automatic, bidrectional mapping of HTTP
-// JSON to RPC. Example:
-//
-// HTTP | RPC
-// -----|-----
-// `GET /v1/messages/123456/foo`  | `GetMessage(message_id: "123456" sub: SubMessage(subfield: "foo"))`
-//
-// In general, not only fields but also field paths can be referenced
-// from a path pattern. Fields mapped to the path pattern cannot be
-// repeated and must have a primitive (non-message) type.
-//
-// Any fields in the request message which are not bound by the path
-// pattern automatically become (optional) HTTP query
-// parameters. Assume the following definition of the request message:
-//
-//
-//     service Messaging {
-//       rpc GetMessage(GetMessageRequest) returns (Message) {
-//         option (google.api.http).get = "/v1/messages/{message_id}";
-//       }
-//     }
-//     message GetMessageRequest {
-//       message SubMessage {
-//         string subfield = 1;
-//       }
-//       string message_id = 1; // mapped to the URL
-//       int64 revision = 2;    // becomes a parameter
-//       SubMessage sub = 3;    // `sub.subfield` becomes a parameter
-//     }
-//
-//
-// This enables a HTTP JSON to RPC mapping as below:
-//
-// HTTP | RPC
-// -----|-----
-// `GET /v1/messages/123456?revision=2&sub.subfield=foo` | `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield: "foo"))`
-//
-// Note that fields which are mapped to HTTP parameters must have a
-// primitive type or a repeated primitive type. Message types are not
-// allowed. In the case of a repeated type, the parameter can be
-// repeated in the URL, as in `...?param=A&param=B`.
-//
-// For HTTP method kinds which allow a request body, the `body` field
-// specifies the mapping. Consider a REST update method on the
-// message resource collection:
-//
-//
-//     service Messaging {
-//       rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
-//         option (google.api.http) = {
-//           put: "/v1/messages/{message_id}"
-//           body: "message"
-//         };
-//       }
-//     }
-//     message UpdateMessageRequest {
-//       string message_id = 1; // mapped to the URL
-//       Message message = 2;   // mapped to the body
-//     }
-//
-//
-// The following HTTP JSON to RPC mapping is enabled, where the
-// representation of the JSON in the request body is determined by
-// protos JSON encoding:
-//
-// HTTP | RPC
-// -----|-----
-// `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" message { text: "Hi!" })`
-//
-// The special name `*` can be used in the body mapping to define that
-// every field not bound by the path template should be mapped to the
-// request body.  This enables the following alternative definition of
-// the update method:
-//
-//     service Messaging {
-//       rpc UpdateMessage(Message) returns (Message) {
-//         option (google.api.http) = {
-//           put: "/v1/messages/{message_id}"
-//           body: "*"
-//         };
-//       }
-//     }
-//     message Message {
-//       string message_id = 1;
-//       string text = 2;
-//     }
-//
-//
-// The following HTTP JSON to RPC mapping is enabled:
-//
-// HTTP | RPC
-// -----|-----
-// `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" text: "Hi!")`
-//
-// Note that when using `*` in the body mapping, it is not possible to
-// have HTTP parameters, as all fields not bound by the path end in
-// the body. This makes this option more rarely used in practice of
-// defining REST APIs. The common usage of `*` is in custom methods
-// which don't use the URL at all for transferring data.
-//
-// It is possible to define multiple HTTP methods for one RPC by using
-// the `additional_bindings` option. Example:
-//
-//     service Messaging {
-//       rpc GetMessage(GetMessageRequest) returns (Message) {
-//         option (google.api.http) = {
-//           get: "/v1/messages/{message_id}"
-//           additional_bindings {
-//             get: "/v1/users/{user_id}/messages/{message_id}"
-//           }
-//         };
-//       }
-//     }
-//     message GetMessageRequest {
-//       string message_id = 1;
-//       string user_id = 2;
-//     }
-//
-//
-// This enables the following two alternative HTTP JSON to RPC
-// mappings:
-//
-// HTTP | RPC
-// -----|-----
-// `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
-// `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id: "123456")`
-//
-// # Rules for HTTP mapping
-//
-// The rules for mapping HTTP path, query parameters, and body fields
-// to the request message are as follows:
-//
-// 1. The `body` field specifies either `*` or a field path, or is
-//    omitted. If omitted, it indicates there is no HTTP request body.
-// 2. Leaf fields (recursive expansion of nested messages in the
-//    request) can be classified into three types:
-//     (a) Matched in the URL template.
-//     (b) Covered by body (if body is `*`, everything except (a) fields;
-//         else everything under the body field)
-//     (c) All other fields.
-// 3. URL query parameters found in the HTTP request are mapped to (c) fields.
-// 4. Any body sent with an HTTP request can contain only (b) fields.
-//
-// The syntax of the path template is as follows:
-//
-//     Template = "/" Segments [ Verb ] ;
-//     Segments = Segment { "/" Segment } ;
-//     Segment  = "*" | "**" | LITERAL | Variable ;
-//     Variable = "{" FieldPath [ "=" Segments ] "}" ;
-//     FieldPath = IDENT { "." IDENT } ;
-//     Verb     = ":" LITERAL ;
-//
-// The syntax `*` matches a single path segment. The syntax `**` matches zero
-// or more path segments, which must be the last part of the path except the
-// `Verb`. The syntax `LITERAL` matches literal text in the path.
-//
-// The syntax `Variable` matches part of the URL path as specified by its
-// template. A variable template must not contain other variables. If a variable
-// matches a single path segment, its template may be omitted, e.g. `{var}`
-// is equivalent to `{var=*}`.
-//
-// If a variable contains exactly one path segment, such as `"{var}"` or
-// `"{var=*}"`, when such a variable is expanded into a URL path, all characters
-// except `[-_.~0-9a-zA-Z]` are percent-encoded. Such variables show up in the
-// Discovery Document as `{var}`.
-//
-// If a variable contains one or more path segments, such as `"{var=foo/*}"`
-// or `"{var=**}"`, when such a variable is expanded into a URL path, all
-// characters except `[-_.~/0-9a-zA-Z]` are percent-encoded. Such variables
-// show up in the Discovery Document as `{+var}`.
-//
-// NOTE: While the single segment variable matches the semantics of
-// [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2
-// Simple String Expansion, the multi segment variable **does not** match
-// RFC 6570 Reserved Expansion. The reason is that the Reserved Expansion
-// does not expand special characters like `?` and `#`, which would lead
-// to invalid URLs.
-//
-// NOTE: the field paths in variables and in the `body` must not refer to
-// repeated fields or map fields.

Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true.\n\nThe server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects.

If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the \"next key\".\n\nThis field is not supported when watch is true.

+How to use klog
+===============
+- Replace imports for `github.com/golang/glog` with `k8s.io/klog`
+- Use `klog.InitFlags(nil)` explicitly for initializing global flags as we no longer use `init()` method to register the flags
+- You can now use `log-file` instead of `log-dir` for logging to a single file (See `examples/log_file/usage_log_file.go`)
+- If you want to redirect everything logged using klog somewhere else (say syslog!), you can use `klog.SetOutput()` method and supply a `io.Writer`. (See `examples/set_output/usage_set_output.go`)
+- For more logging conventions (See [Logging Conventions](https://github.com/kubernetes/community/blob/master/contributors/devel/logging.md))
+
+### Coexisting with glog
+This package can be used side by side with glog. [This example](examples/coexist_glog/coexist_glog.go) shows how to initialize and syncronize flags from the global `flag.CommandLine` FlagSet. In addition, the example makes use of stderr as combined output by setting `alsologtostderr` (or `logtostderr`) to `true`.
