+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,

+
+OpenCensus Go is a Go implementation of OpenCensus, a toolkit for
+collecting application performance and behavior monitoring data.
+Currently it consists of three major components: tags, stats and tracing.
+
+## Installation
+
+```
+$ go get -u go.opencensus.io
+```
+
+The API of this project is still evolving, see: [Deprecation Policy](#deprecation-policy).
+The use of vendoring or a dependency management tool is recommended.
+
+## Prerequisites
+
+OpenCensus Go libraries require Go 1.8 or later.
+
+## Getting Started
+
+The easiest way to get started using OpenCensus in your application is to use an existing
+integration with your RPC framework:
+
+* [net/http](https://godoc.org/go.opencensus.io/plugin/ochttp)
+* [gRPC](https://godoc.org/go.opencensus.io/plugin/ocgrpc)
+* [database/sql](https://godoc.org/github.com/opencensus-integrations/ocsql)
+* [Go kit](https://godoc.org/github.com/go-kit/kit/tracing/opencensus)
+* [Groupcache](https://godoc.org/github.com/orijtech/groupcache)
+* [Caddy webserver](https://godoc.org/github.com/orijtech/caddy)
+* [MongoDB](https://godoc.org/github.com/orijtech/mongo-go-driver)
+* [Redis gomodule/redigo](https://godoc.org/github.com/orijtech/redigo)
+* [Redis goredis/redis](https://godoc.org/github.com/orijtech/redis)
+* [Memcache](https://godoc.org/github.com/orijtech/gomemcache)
+
+If you're using a framework not listed here, you could either implement your own middleware for your
+framework or use [custom stats](#stats) and [spans](#spans) directly in your application.
+
+## Exporters
+
+OpenCensus can export instrumentation data to various backends.
+OpenCensus has exporter implementations for the following, users
+can implement their own exporters by implementing the exporter interfaces
+([stats](https://godoc.org/go.opencensus.io/stats/view#Exporter),
+[trace](https://godoc.org/go.opencensus.io/trace#Exporter)):
+
+* [Prometheus][exporter-prom] for stats
+* [OpenZipkin][exporter-zipkin] for traces
+* [Stackdriver][exporter-stackdriver] Monitoring for stats and Trace for traces
+* [Jaeger][exporter-jaeger] for traces
+* [AWS X-Ray][exporter-xray] for traces
+* [Datadog][exporter-datadog] for stats and traces
+* [Graphite][exporter-graphite] for stats
+* [Honeycomb][exporter-honeycomb] for traces
+
+## Overview
+
+![OpenCensus Overview](https://i.imgur.com/cf4ElHE.jpg)
+
+In a microservices environment, a user request may go through
+multiple services until there is a response. OpenCensus allows
+you to instrument your services and collect diagnostics data all
+through your services end-to-end.
+
+## Tags
+
+Tags represent propagated key-value pairs. They are propagated using `context.Context`
+in the same process or can be encoded to be transmitted on the wire. Usually, this will
+be handled by an integration plugin, e.g. `ocgrpc.ServerHandler` and `ocgrpc.ClientHandler`
+for gRPC.
+
+Package `tag` allows adding or modifying tags in the current context.
+
+[embedmd]:# (internal/readme/tags.go new)
+```go
+ctx, err = tag.New(ctx,
+	tag.Insert(osKey, "macOS-10.12.5"),
+	tag.Upsert(userIDKey, "cde36753ed"),
+)
+if err != nil {
+	log.Fatal(err)
+}
+```
+
+## Stats
+
+OpenCensus is a low-overhead framework even if instrumentation is always enabled.
+In order to be so, it is optimized to make recording of data points fast
+and separate from the data aggregation.
+
+OpenCensus stats collection happens in two stages:
+
+* Definition of measures and recording of data points
+* Definition of views and aggregation of the recorded data
+
+### Recording
+
+Measurements are data points associated with a measure.
+Recording implicitly tags the set of Measurements with the tags from the
+provided context:
+
+[embedmd]:# (internal/readme/stats.go record)
+```go
+stats.Record(ctx, videoSize.M(102478))
+```
+
+### Views
+
+Views are how Measures are aggregated. You can think of them as queries over the
+set of recorded data points (measurements).
+
+Views have two parts: the tags to group by and the aggregation type used.
+
+Currently three types of aggregations are supported:
+* CountAggregation is used to count the number of times a sample was recorded.
+* DistributionAggregation is used to provide a histogram of the values of the samples.
+* SumAggregation is used to sum up all sample values.
+
+[embedmd]:# (internal/readme/stats.go aggs)
+```go
+distAgg := view.Distribution(0, 1<<32, 2<<32, 3<<32)
+countAgg := view.Count()
+sumAgg := view.Sum()
+```
+
+Here we create a view with the DistributionAggregation over our measure.
+
+[embedmd]:# (internal/readme/stats.go view)
+```go
+if err := view.Register(&view.View{
+	Name:        "example.com/video_size_distribution",
+	Description: "distribution of processed video size over time",
+	Measure:     videoSize,
+	Aggregation: view.Distribution(0, 1<<32, 2<<32, 3<<32),
+}); err != nil {
+	log.Fatalf("Failed to register view: %v", err)
+}
+```
+
+Register begins collecting data for the view. Registered views' data will be
+exported via the registered exporters.
+
+## Traces
+
+A distributed trace tracks the progression of a single user request as
+it is handled by the services and processes that make up an application.
+Each step is called a span in the trace. Spans include metadata about the step,
+including especially the time spent in the step, called the span’s latency.
+
+Below you see a trace and several spans underneath it.
+
+![Traces and spans](https://i.imgur.com/7hZwRVj.png)
+
+### Spans
+
+Span is the unit step in a trace. Each span has a name, latency, status and
+additional metadata.
+
+Below we are starting a span for a cache read and ending it
+when we are done:
+
+[embedmd]:# (internal/readme/trace.go startend)
+```go
+ctx, span := trace.StartSpan(ctx, "cache.Get")
+defer span.End()
+
+// Do work to get from cache.
+```
+
+### Propagation
+
+Spans can have parents or can be root spans if they don't have any parents.
+The current span is propagated in-process and across the network to allow associating
+new child spans with the parent.
+
+In the same process, `context.Context` is used to propagate spans.
+`trace.StartSpan` creates a new span as a root if the current context
+doesn't contain a span. Or, it creates a child of the span that is
+already in current context. The returned context can be used to keep
+propagating the newly created span in the current context.
+
+[embedmd]:# (internal/readme/trace.go startend)
+```go
+ctx, span := trace.StartSpan(ctx, "cache.Get")
+defer span.End()
+
+// Do work to get from cache.
+```
+
+Across the network, OpenCensus provides different propagation
+methods for different protocols.
+
+* gRPC integrations use the OpenCensus' [binary propagation format](https://godoc.org/go.opencensus.io/trace/propagation).
+* HTTP integrations use Zipkin's [B3](https://github.com/openzipkin/b3-propagation)
+  by default but can be configured to use a custom propagation method by setting another
+  [propagation.HTTPFormat](https://godoc.org/go.opencensus.io/trace/propagation#HTTPFormat).
+
+## Execution Tracer
+
+With Go 1.11, OpenCensus Go will support integration with the Go execution tracer.
+See [Debugging Latency in Go](https://medium.com/observability/debugging-latency-in-go-1-11-9f97a7910d68)
+for an example of their mutual use.
+
+## Profiles
+
+OpenCensus tags can be applied as profiler labels
+for users who are on Go 1.9 and above.
+
+[embedmd]:# (internal/readme/tags.go profiler)
+```go
+ctx, err = tag.New(ctx,
+	tag.Insert(osKey, "macOS-10.12.5"),
+	tag.Insert(userIDKey, "fff0989878"),
+)
+if err != nil {
+	log.Fatal(err)
+}
+tag.Do(ctx, func(ctx context.Context) {
+	// Do work.
+	// When profiling is on, samples will be
+	// recorded with the key/values from the tag map.
+})
+```
+

+![CPU profile](https://i.imgur.com/jBKjlkw.png)
+
+## Deprecation Policy
+
+Before version 1.0.0, the following deprecation policy will be observed:
+
+No backwards-incompatible changes will be made except for the removal of symbols that have
+been marked as *Deprecated* for at least one minor release (e.g. 0.9.0 to 0.10.0). A release
+removing the *Deprecated* functionality will be made no sooner than 28 days after the first
+release in which the functionality was marked *Deprecated*.

+
+A measure represents a type of data point to be tracked and recorded.
+For example, latency, request Mb/s, and response Mb/s are measures
+to collect from a server.
+
+Measure constructors such as Int64 and Float64 automatically
+register the measure by the given name. Each registered measure needs
+to be unique by name. Measures also have a description and a unit.
+
+Libraries can define and export measures. Application authors can then
+create views and collect and break down measures by the tags they are
+interested in.
+
+Recording measurements
+
+Measurement is a data point to be collected for a measure. For example,
+for a latency (ms) measure, 100 is a measurement that represents a 100ms
+latency event. Measurements are created from measures with
+the current context. Tags from the current context are recorded with the
+measurements if they are any.
+
+Recorded measurements are dropped immediately if no views are registered for them.
+There is usually no need to conditionally enable and disable
+recording to reduce cost. Recording of measurements is cheap.
+
+Libraries can always record measurements, and applications can later decide
+on which measurements they want to collect by registering views. This allows
+libraries to turn on the instrumentation by default.
+
+Exemplars
+
+For a given recorded measurement, the associated exemplar is a diagnostic map
+that gives more information about the measurement.
+
+When aggregated using a Distribution aggregation, an exemplar is kept for each
+bucket in the Distribution. This allows you to easily find an example of a
+measurement that fell into each bucket.
+
+For example, if you also use the OpenCensus trace package and you
+record a measurement with a context that contains a sampled trace span,
+then the trace span will be added to the exemplar associated with the measurement.
+
+When exported to a supporting back end, you should be able to easily navigate
+to example traces that fell into each bucket in the Distribution.

+// Package view contains support for collecting and exposing aggregates over stats.
+//
+// In order to collect measurements, views need to be defined and registered.
+// A view allows recorded measurements to be filtered and aggregated.
+//
+// All recorded measurements can be grouped by a list of tags.
+//
+// OpenCensus provides several aggregation methods: Count, Distribution and Sum.
+//
+// Count only counts the number of measurement points recorded.
+// Distribution provides statistical summary of the aggregated data by counting
+// how many recorded measurements fall into each bucket.
+// Sum adds up the measurement values.
+// LastValue just keeps track of the most recently recorded measurement value.
+// All aggregations are cumulative.
+//
+// Views can be registerd and unregistered at any time during program execution.
+//
+// Libraries can define views but it is recommended that in most cases registering
+// views be left up to applications.
+//
+// Exporting
+//
+// Collected and aggregated data can be exported to a metric collection
+// backend by registering its exporter.
+//
+// Multiple exporters can be registered to upload the data to various
+// different back ends.

+Package trace contains support for OpenCensus distributed tracing.
+
+The following assumes a basic familiarity with OpenCensus concepts.
+See http://opencensus.io
+
+
+Exporting Traces
+
+To export collected tracing data, register at least one exporter. You can use
+one of the provided exporters or write your own.
+
+    trace.RegisterExporter(exporter)
+
+By default, traces will be sampled relatively rarely. To change the sampling
+frequency for your entire program, call ApplyConfig. Use a ProbabilitySampler
+to sample a subset of traces, or use AlwaysSample to collect a trace on every run:
+
+    trace.ApplyConfig(trace.Config{DefaultSampler: trace.AlwaysSample()})
+
+Be careful about using trace.AlwaysSample in a production application with
+significant traffic: a new trace will be started and exported for every request.
+
+Adding Spans to a Trace
+
+A trace consists of a tree of spans. In Go, the current span is carried in a
+context.Context.
+
+It is common to want to capture all the activity of a function call in a span. For
+this to work, the function must take a context.Context as a parameter. Add these two
+lines to the top of the function:
+
+    ctx, span := trace.StartSpan(ctx, "example.com/Run")
+    defer span.End()
+
+StartSpan will create a new top-level span if the context
+doesn't contain another span, otherwise it will create a child span.

+// Package publicsuffix provides a public suffix list based on data from
+// https://publicsuffix.org/
+//
+// A public suffix is one under which Internet users can directly register
+// names. It is related to, but different from, a TLD (top level domain).
+//
+// "com" is a TLD (top level domain). Top level means it has no dots.
+//
+// "com" is also a public suffix. Amazon and Google have registered different
+// siblings under that domain: "amazon.com" and "google.com".
+//
+// "au" is another TLD, again because it has no dots. But it's not "amazon.au".
+// Instead, it's "amazon.com.au".
+//
+// "com.au" isn't an actual TLD, because it's not at the top level (it has
+// dots). But it is an eTLD (effective TLD), because that's the branching point
+// for domain name registrars.
+//
+// Another name for "an eTLD" is "a public suffix". Often, what's more of
+// interest is the eTLD+1, or one more label than the public suffix. For
+// example, browsers partition read/write access to HTTP cookies according to
+// the eTLD+1. Web pages served from "amazon.com.au" can't read cookies from
+// "google.com.au", but web pages served from "maps.google.com" can share
+// cookies from "www.google.com", so you don't have to sign into Google Maps
+// separately from signing into Google Web Search. Note that all four of those
+// domains have 3 labels and 2 dots. The first two domains are each an eTLD+1,
+// the last two are not (but share the same eTLD+1: "google.com").
+//
+// All of these domains have the same eTLD+1:
+//  - "www.books.amazon.co.uk"
+//  - "books.amazon.co.uk"
+//  - "amazon.co.uk"
+// Specifically, the eTLD+1 is "amazon.co.uk", because the eTLD is "co.uk".
+//
+// There is no closed form algorithm to calculate the eTLD of a domain.
+// Instead, the calculation is data driven. This package provides a
+// pre-compiled snapshot of Mozilla's PSL (Public Suffix List) data at
+// https://publicsuffix.org/

+Package trace implements tracing of requests and long-lived objects.
+It exports HTTP interfaces on /debug/requests and /debug/events.
+
+A trace.Trace provides tracing for short-lived objects, usually requests.
+A request handler might be implemented like this:
+
+	func fooHandler(w http.ResponseWriter, req *http.Request) {
+		tr := trace.New("mypkg.Foo", req.URL.Path)
+		defer tr.Finish()
+		...
+		tr.LazyPrintf("some event %q happened", str)
+		...
+		if err := somethingImportant(); err != nil {
+			tr.LazyPrintf("somethingImportant failed: %v", err)
+			tr.SetError()
+		}
+	}
+
+The /debug/requests HTTP endpoint organizes the traces by family,
+errors, and duration.  It also provides histogram of request duration
+for each family.
+
+A trace.EventLog provides tracing for long-lived objects, such as RPC
+connections.
+
+	// A Fetcher fetches URL paths for a single domain.
+	type Fetcher struct {
+		domain string
+		events trace.EventLog
+	}

+			return "", err

+		...
+	}
+
+	func (f *Fetcher) Close() error {

+		return nil
+	}
+
+The /debug/events HTTP endpoint organizes the event logs by family and

-// Package google provides support for making OAuth2 authorized and authenticated
-// HTTP requests to Google APIs. It supports the Web server flow, client-side
-// credentials, service accounts, Google Compute Engine service accounts, and Google
-// App Engine service accounts.

-// A brief overview of the package follows. For more information, please read
-// https://developers.google.com/accounts/docs/OAuth2
-// and
-// https://developers.google.com/accounts/docs/application-default-credentials.
-//
-// OAuth2 Configs
-//
-// Two functions in this package return golang.org/x/oauth2.Config values from Google credential
-// data. Google supports two JSON formats for OAuth2 credentials: one is handled by ConfigFromJSON,
-// the other by JWTConfigFromJSON. The returned Config can be used to obtain a TokenSource or
-// create an http.Client.
-//
-//
-// Credentials
-//
-// The DefaultCredentials type represents Google Application Default Credentials, as
-// well as other forms of credential.
-//
-// Use FindDefaultCredentials to obtain Application Default Credentials.
-// FindDefaultCredentials looks in some well-known places for a credentials file, and
-// will call AppEngineTokenSource or ComputeTokenSource as needed.
-//
-// DefaultClient and DefaultTokenSource are convenience methods. They first call FindDefaultCredentials,
-// then use the credentials to construct an http.Client or an oauth2.TokenSource.
-//
-// Use CredentialsFromJSON to obtain credentials from either of the two JSON
-// formats described in OAuth2 Configs, above. (The DefaultCredentials returned may
-// not be "Application Default Credentials".) The TokenSource in the returned value
-// is the same as the one obtained from the oauth2.Config returned from
-// ConfigFromJSON or JWTConfigFromJSON, but the DefaultCredentials may contain
-// additional information that is useful is some circumstances.

+This program reads a file containing function prototypes
+(like syscall_aix.go) and generates system call bodies.
+The prototypes are marked by lines beginning with "//sys"
+and read like func declarations if //sys is replaced by func, but:
+	* The parameter lists must give a name for each argument.
+	  This includes return parameters.
+	* The parameter lists must give a type for each argument:
+	  the (x, y, z int) shorthand is not allowed.
+	* If the return parameter is an error number, it must be named err.
+	* If go func name needs to be different than its libc name,
+	* or the function is not in libc, name could be specified
+	* at the end, after "=" sign, like
+	  //sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
+
+
+This program will generate three files and handle both gc and gccgo implementation:
+  - zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
+  - zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
+  - zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
+
+ The generated code looks like this
+
+zsyscall_aix_ppc64.go

+	 // Pointer Creation
+	 r1, e1 := callasyscall(...)
+	 // Type Conversion

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,

+
+// The `Status` type defines a logical error model that is suitable for different
+// programming environments, including REST APIs and RPC APIs. It is used by
+// [gRPC](https://github.com/grpc). The error model is designed to be:
+//
+// - Simple to use and understand for most users
+// - Flexible enough to meet unexpected needs
+//
+// # Overview
+//
+// The `Status` message contains three pieces of data: error code, error message,
+// and error details. The error code should be an enum value of
+// [google.rpc.Code][google.rpc.Code], but it may accept additional error codes if needed.  The
+// error message should be a developer-facing English message that helps
+// developers *understand* and *resolve* the error. If a localized user-facing
+// error message is needed, put the localized message in the error details or
+// localize it in the client. The optional error details may contain arbitrary
+// information about the error. There is a predefined set of error detail types
+// in the package `google.rpc` that can be used for common error conditions.
+//
+// # Language mapping
+//
+// The `Status` message is the logical representation of the error model, but it
+// is not necessarily the actual wire format. When the `Status` message is
+// exposed in different client libraries and different wire protocols, it can be
+// mapped differently. For example, it will likely be mapped to some exceptions
+// in Java, but more likely mapped to some error codes in C.
+//
+// # Other uses
+//
+// The error model and the `Status` message can be used in a variety of
+// environments, either with or without APIs, to provide a
+// consistent developer experience across different environments.
+//
+// Example uses of this error model include:
+//
+// - Partial errors. If a service needs to return partial errors to the client,
+//     it may embed the `Status` in the normal response to indicate the partial
+//     errors.
+//
+// - Workflow errors. A typical workflow has multiple steps. Each step may
+//     have a `Status` message for error reporting.
+//
+// - Batch operations. If a client uses batch request and batch response, the
+//     `Status` message should be used directly inside batch response, one for
+//     each error sub-response.
+//
+// - Asynchronous operations. If an API call embeds asynchronous operation
+//     results in its response, the status of those operations should be
+//     represented directly using the `Status` message.
+//
+// - Logging. If some API errors are stored in logs, the message `Status` could
+//     be used directly after any stripping needed for security/privacy reasons.

+// `FieldMask` represents a set of symbolic field paths, for example:
+//
+//     paths: "f.a"
+//     paths: "f.b.d"
+//
+// Here `f` represents a field in some root message, `a` and `b`
+// fields in the message found in `f`, and `d` a field found in the
+// message in `f.b`.
+//
+// Field masks are used to specify a subset of fields that should be
+// returned by a get operation or modified by an update operation.
+// Field masks also have a custom JSON encoding (see below).
+//
+// # Field Masks in Projections
+//
+// When used in the context of a projection, a response message or
+// sub-message is filtered by the API to only contain those fields as
+// specified in the mask. For example, if the mask in the previous
+// example is applied to a response message as follows:
+//
+//     f {
+//       a : 22
+//       b {
+//         d : 1
+//         x : 2
+//       }
+//       y : 13
+//     }
+//     z: 8
+//
+// The result will not contain specific values for fields x,y and z
+// (their value will be set to the default, and omitted in proto text
+// output):
+//
+//
+//     f {
+//       a : 22
+//       b {
+//         d : 1
+//       }
+//     }
+//
+// A repeated field is not allowed except at the last position of a
+// paths string.
+//
+// If a FieldMask object is not present in a get operation, the
+// operation applies to all fields (as if a FieldMask of all fields
+// had been specified).
+//
+// Note that a field mask does not necessarily apply to the
+// top-level response message. In case of a REST get operation, the
+// field mask applies directly to the response, but in case of a REST
+// list operation, the mask instead applies to each individual message
+// in the returned resource list. In case of a REST custom method,
+// other definitions may be used. Where the mask applies will be
+// clearly documented together with its declaration in the API.  In
+// any case, the effect on the returned resource/resources is required
+// behavior for APIs.
+//
+// # Field Masks in Update Operations
+//
+// A field mask in update operations specifies which fields of the
+// targeted resource are going to be updated. The API is required
+// to only change the values of the fields as specified in the mask
+// and leave the others untouched. If a resource is passed in to
+// describe the updated values, the API ignores the values of all
+// fields not covered by the mask.
+//
+// If a repeated field is specified for an update operation, new values will
+// be appended to the existing repeated field in the target resource. Note that
+// a repeated field is only allowed in the last position of a `paths` string.
+//
+// If a sub-message is specified in the last position of the field mask for an
+// update operation, then new value will be merged into the existing sub-message
+// in the target resource.
+//
+// For example, given the target message:
+//
+//     f {
+//       b {
+//         d: 1
+//         x: 2
+//       }
+//       c: [1]
+//     }
+//
+// And an update message:
+//
+//     f {
+//       b {
+//         d: 10
+//       }
+//       c: [2]
+//     }
+//
+// then if the field mask is:
+//
+//  paths: ["f.b", "f.c"]
+//
+// then the result will be:
+//
+//     f {
+//       b {
+//         d: 10
+//         x: 2
+//       }
+//       c: [1, 2]
+//     }
+//
+// An implementation may provide options to override this default behavior for
+// repeated and message fields.
+//
+// In order to reset a field's value to the default, the field must
+// be in the mask and set to the default value in the provided resource.
+// Hence, in order to reset all fields of a resource, provide a default
+// instance of the resource and set all fields in the mask, or do
+// not provide a mask as described below.
+//
+// If a field mask is not present on update, the operation applies to
+// all fields (as if a field mask of all fields has been specified).
+// Note that in the presence of schema evolution, this may mean that
+// fields the client does not know and has therefore not filled into
+// the request will be reset to their default. If this is unwanted
+// behavior, a specific service may require a client to always specify
+// a field mask, producing an error if not.
+//
+// As with get operations, the location of the resource which
+// describes the updated values in the request message depends on the
+// operation kind. In any case, the effect of the field mask is
+// required to be honored by the API.
+//
+// ## Considerations for HTTP REST
+//
+// The HTTP kind of an update operation which uses a field mask must
+// be set to PATCH instead of PUT in order to satisfy HTTP semantics
+// (PUT must only be used for full updates).
+//
+// # JSON Encoding of Field Masks
+//
+// In JSON, a field mask is encoded as a single string where paths are
+// separated by a comma. Fields name in each path are converted
+// to/from lower-camel naming conventions.
+//
+// As an example, consider the following message declarations:
+//
+//     message Profile {
+//       User user = 1;
+//       Photo photo = 2;
+//     }
+//     message User {
+//       string display_name = 1;
+//       string address = 2;
+//     }
+//
+// In proto a field mask for `Profile` may look as such:
+//
+//     mask {
+//       paths: "user.display_name"
+//       paths: "photo"
+//     }
+//
+// In JSON, the same mask is represented as below:
+//
+//     {
+//       mask: "user.displayName,photo"
+//     }
+//
+// # Field Masks and Oneof Fields
+//
+// Field masks treat fields in oneofs just as regular fields. Consider the
+// following message:
+//
+//     message SampleMessage {
+//       oneof test_oneof {
+//         string name = 4;
+//         SubMessage sub_message = 9;
+//       }
+//     }
+//
+// The field mask can be:
+//
+//     mask {
+//       paths: "name"
+//     }
+//
+// Or:
+//
+//     mask {
+//       paths: "sub_message"
+//     }
+//
+// Note that oneof type names ("test_oneof" in this case) cannot be used in
+// paths.
+//
+// ## Field Mask Verification
+//
+// The implementation of any API method which has a FieldMask type field in the
+// request should verify the included field paths, and return an
+// `INVALID_ARGUMENT` error if any path is duplicated or unmappable.

+# How to contribute
+
+We definitely welcome your patches and contributions to gRPC!
+
+If you are new to github, please start by reading [Pull Request howto](https://help.github.com/articles/about-pull-requests/)
+
+## Legal requirements
+
+In order to protect both you and ourselves, you will need to sign the
+[Contributor License Agreement](https://identity.linuxfoundation.org/projects/cncf).
+
+## Guidelines for Pull Requests
+How to get your contributions merged smoothly and quickly.
+ 
+- Create **small PRs** that are narrowly focused on **addressing a single concern**. We often times receive PRs that are trying to fix several things at a time, but only one fix is considered acceptable, nothing gets merged and both author's & review's time is wasted. Create more PRs to address different concerns and everyone will be happy.
+ 
+- For speculative changes, consider opening an issue and discussing it first. If you are suggesting a behavioral or API change, consider starting with a [gRFC proposal](https://github.com/grpc/proposal). 
+ 
+- Provide a good **PR description** as a record of **what** change is being made and **why** it was made. Link to a github issue if it exists.
+ 
+- Don't fix code style and formatting unless you are already changing that line to address an issue. PRs with irrelevant changes won't be merged. If you do want to fix formatting or style, do that in a separate PR.
+ 
+- Unless your PR is trivial, you should expect there will be reviewer comments that you'll need to address before merging. We expect you to be reasonably responsive to those comments, otherwise the PR will be closed after 2-3 weeks of inactivity.
+ 
+- Maintain **clean commit history** and use **meaningful commit messages**. PRs with messy commit history are difficult to review and won't be merged. Use `rebase -i upstream/master` to curate your commit history and/or to bring in latest changes from master (but avoid rebasing in the middle of a code review).
+ 
+- Keep your PR up to date with upstream/master (if there are merge conflicts, we can't really merge your change).
+ 
+- **All tests need to be passing** before your change can be merged. We recommend you **run tests locally** before creating your PR to catch breakages early on.
+  - `make all` to test everything, OR
+  - `make vet` to catch vet errors
+  - `make test` to run the tests
+  - `make testrace` to run tests in race mode
+
+- Exceptions to the rules can be made if there's a compelling reason for doing so.

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+# gRPC-Go
+
+[![Build Status](https://travis-ci.org/grpc/grpc-go.svg)](https://travis-ci.org/grpc/grpc-go) [![GoDoc](https://godoc.org/google.golang.org/grpc?status.svg)](https://godoc.org/google.golang.org/grpc) [![GoReportCard](https://goreportcard.com/badge/grpc/grpc-go)](https://goreportcard.com/report/github.com/grpc/grpc-go)
+
+The Go implementation of [gRPC](https://grpc.io/): A high performance, open source, general RPC framework that puts mobile and HTTP/2 first. For more information see the [gRPC Quick Start: Go](https://grpc.io/docs/quickstart/go.html) guide.
+
+Installation
+------------
+
+To install this package, you need to install Go and setup your Go workspace on your computer. The simplest way to install the library is to run:
+
+```
+$ go get -u google.golang.org/grpc
+```
+
+Prerequisites
+-------------
+
+gRPC-Go requires Go 1.9 or later.
+
+Constraints
+-----------
+The grpc package should only depend on standard Go packages and a small number of exceptions. If your contribution introduces new dependencies which are NOT in the [list](http://godoc.org/google.golang.org/grpc?imports), you need a discussion with gRPC-Go authors and consultants.
+
+Documentation
+-------------
+See [API documentation](https://godoc.org/google.golang.org/grpc) for package and API descriptions and find examples in the [examples directory](examples/).
+
+Performance
+-----------
+See the current benchmarks for some of the languages supported in [this dashboard](https://performance-dot-grpc-testing.appspot.com/explore?dashboard=5652536396611584&widget=490377658&container=1286539696).
+
+Status
+------
+General Availability [Google Cloud Platform Launch Stages](https://cloud.google.com/terms/launch-stages).
+
+FAQ
+---
+
+#### Compiling error, undefined: grpc.SupportPackageIsVersion
+
+Please update proto package, gRPC package and rebuild the proto files:
+ - `go get -u github.com/golang/protobuf/{proto,protoc-gen-go}`
+ - `go get -u google.golang.org/grpc`
+ - `protoc --go_out=plugins=grpc:. *.proto`
+
+#### How to turn on logging
+
+The default logger is controlled by the environment variables. Turn everything
+on by setting:
+
+```
+GRPC_GO_LOG_VERBOSITY_LEVEL=99 GRPC_GO_LOG_SEVERITY_LEVEL=info
+```
+
+#### The RPC failed with error `"code = Unavailable desc = transport is closing"`
+
+This error means the connection the RPC is using was closed, and there are many
+possible reasons, including:
+ 1. mis-configured transport credentials, connection failed on handshaking
+ 1. bytes disrupted, possibly by a proxy in between
+ 1. server shutdown
+
+It can be tricky to debug this because the error happens on the client side but
+the root cause of the connection being closed is on the server side. Turn on
+logging on __both client and server__, and see if there are any transport
+errors.
