+ 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,
+ 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.

+// # gRPC Transcoding
+//
+// gRPC Transcoding is a feature for mapping between a gRPC method and one or
+// more HTTP REST endpoints. It allows developers to build a single API service
+// that supports both gRPC APIs and REST APIs. Many systems, including [Google
+// APIs](https://github.com/googleapis/googleapis),
+// [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
+// Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
+// and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
+// and use it for large scale production services.
+//
+// `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
+// how different portions of the gRPC request message are mapped to the URL
+// path, URL query parameters, and HTTP request body. It also controls how the
+// gRPC response message is mapped to the HTTP response body. `HttpRule` is
+// typically specified as an `google.api.http` annotation on the gRPC method.
+//
+// Each mapping specifies a URL path template and an HTTP method. The path
+// template may refer to one or more fields in the gRPC request message, as long
+// as each field is a non-repeated field with a primitive (non-message) type.
+// The path template controls how fields of the request message are mapped to
+// the URL path.
+//
+// Example:
+//
+// service Messaging {
+// rpc GetMessage(GetMessageRequest) returns (Message) {
+// option (google.api.http) = {
+// get: "/v1/{name=messages/*}"
+// };
+// }
+// }
+// message GetMessageRequest {
+// string name = 1; // Mapped to URL path.
+// }
+// message Message {
+// string text = 1; // The resource content.
+// }
+//
+// This enables an HTTP REST to gRPC mapping as below:
+//
+// HTTP | gRPC
+// -----|-----
+// `GET /v1/messages/123456` | `GetMessage(name: "messages/123456")`
+//
+// Any fields in the request message which are not bound by the path template
+// automatically become HTTP query parameters if there is no HTTP request body.
+// For example:
+//
+// 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 URL path.
+// int64 revision = 2; // Mapped to URL query parameter `revision`.
+// SubMessage sub = 3; // Mapped to URL query parameter `sub.subfield`.
+// }
+//
+// This enables a HTTP JSON to RPC mapping as below:
+//
+// HTTP | gRPC
+// -----|-----
+// `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 URL query parameters must have a
+// primitive type or a repeated primitive type or a non-repeated message type.
+// In the case of a repeated type, the parameter can be repeated in the URL
+// as `...?param=A¶m=B`. In the case of a message type, each field of the
+// message is mapped to a separate parameter, such as
+// `...?foo.a=A&foo.b=B&foo.c=C`.
+//
+// For HTTP methods that 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) = {
+// patch: "/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 | gRPC
+// -----|-----
+// `PATCH /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) = {
+// patch: "/v1/messages/{message_id}"
+// body: "*"
+// };
+// }
+// }
+// message Message {
+// string message_id = 1;
+// string text = 2;
+// }
+//
+//
+// The following HTTP JSON to RPC mapping is enabled:
+//
+// HTTP | gRPC
+// -----|-----
+// `PATCH /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 when
+// 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 | gRPC
+// -----|-----
+// `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
+//
+// 1. Leaf request fields (recursive expansion nested messages in the request
+// message) are classified into three categories:
+// - Fields referred by the path template. They are passed via the URL path.
+// - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+// request body.
+// - All other fields are passed via the URL query parameters, and the
+// parameter name is the field path in the request message. A repeated
+// field can be represented as multiple query parameters under the same
+// name.
+// 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+// are passed via URL path and HTTP request body.
+// 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+// fields are passed via URL path and URL query parameters.
+//
+// ### Path template syntax
+//
+// Template = "/" Segments [ Verb ] ;
+// Segments = Segment { "/" Segment } ;
+// Segment = "*" | "**" | LITERAL | Variable ;
+// Variable = "{" FieldPath [ "=" Segments ] "}" ;
+// FieldPath = IDENT { "." IDENT } ;
+// Verb = ":" LITERAL ;
+//
+// The syntax `*` matches a single URL path segment. The syntax `**` matches
+// zero or more URL path segments, which must be the last part of the URL path
+// except the `Verb`.
+//
+// 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=*}`.
+//
+// The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+// contains any reserved character, such characters should be percent-encoded
+// before the matching.
+//
+// If a variable contains exactly one path segment, such as `"{var}"` or
+// `"{var=*}"`, when such a variable is expanded into a URL path on the client
+// side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+// server side does the reverse decoding. Such variables show up in the
+// [Discovery
+// Document](https://developers.google.com/discovery/v1/reference/apis) as
+// `{var}`.
+//
+// If a variable contains multiple path segments, such as `"{var=foo/*}"`
+// or `"{var=**}"`, when such a variable is expanded into a URL path on the
+// client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+// The server side does the reverse decoding, except "%2F" and "%2f" are left
+// unchanged. Such variables show up in the
+// [Discovery
+// Document](https://developers.google.com/discovery/v1/reference/apis) as
+// `{+var}`.
+//
+// ## Using gRPC API Service Configuration
+//
+// gRPC API Service Configuration (service config) is a configuration language
+// for configuring a gRPC service to become a user-facing product. The
+// service config is simply the YAML representation of the `google.api.Service`
+// proto message.
+//
+// As an alternative to annotating your proto file, you can configure gRPC
+// transcoding in your service config YAML files. You do this by specifying a
+// `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+// effect as the proto annotation. This can be particularly useful if you
+// have a proto that is reused in multiple services. Note that any transcoding
+// specified in the service config will override any matching transcoding
+// configuration in the proto.
+//
+// Example:
+//
+// http:
+// rules:
+// # Selects a gRPC method and applies HttpRule to it.
+// - selector: example.v1.Messaging.GetMessage
+// get: /v1/messages/{message_id}/{sub.subfield}
+//
+// ## Special notes
+//
+// When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+// proto to JSON conversion must follow the [proto3
+// specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+//
+// While the single segment variable follows the semantics of
+// [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+// Expansion, the multi segment variable **does not** follow RFC 6570 Section
+// 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+// does not expand special characters like `?` and `#`, which would lead
+// to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+// for multi segment variables.
+//
+// The path variables **must not** refer to any repeated or mapped field,
+// because client libraries are not capable of handling such variable expansion.
+//
+// The path variables **must not** capture the leading "/" character. The reason
+// is that the most common use case "{var}" does not capture the leading "/"
+// character. For consistency, all path variables must share the same behavior.
+//
+// Repeated message fields must not be mapped to URL query parameters, because
+// no client library can support such complicated mapping.
+//
+// If an API needs to use a JSON array for request or response body, it can map
+// the request or response body to a repeated field. However, some gRPC
+// Transcoding implementations may not support this feature.

+// A simple descriptor of a resource type.
+//
+// ResourceDescriptor annotates a resource message (either by means of a
+// protobuf annotation or use in the service config), and associates the
+// resource's schema, the resource type, and the pattern of the resource name.
+//
+// Example:
+//
+// message Topic {
+// // Indicates this message defines a resource schema.
+// // Declares the resource type in the format of {service}/{kind}.
+// // For Kubernetes resources, the format is {api group}/{kind}.
+// option (google.api.resource) = {
+// type: "pubsub.googleapis.com/Topic"
+// name_descriptor: {
+// pattern: "projects/{project}/topics/{topic}"
+// parent_type: "cloudresourcemanager.googleapis.com/Project"
+// parent_name_extractor: "projects/{project}"
+// }
+// };
+// }
+//
+// The ResourceDescriptor Yaml config will look like:
+//
+// resources:
+// - type: "pubsub.googleapis.com/Topic"
+// name_descriptor:
+// - pattern: "projects/{project}/topics/{topic}"
+// parent_type: "cloudresourcemanager.googleapis.com/Project"
+// parent_name_extractor: "projects/{project}"
+//
+// Sometimes, resources have multiple patterns, typically because they can
+// live under multiple parents.
+//
+// Example:
+//
+// message LogEntry {
+// option (google.api.resource) = {
+// type: "logging.googleapis.com/LogEntry"
+// name_descriptor: {
+// pattern: "projects/{project}/logs/{log}"
+// parent_type: "cloudresourcemanager.googleapis.com/Project"
+// parent_name_extractor: "projects/{project}"
+// }
+// name_descriptor: {
+// pattern: "folders/{folder}/logs/{log}"
+// parent_type: "cloudresourcemanager.googleapis.com/Folder"
+// parent_name_extractor: "folders/{folder}"
+// }
+// name_descriptor: {
+// pattern: "organizations/{organization}/logs/{log}"
+// parent_type: "cloudresourcemanager.googleapis.com/Organization"
+// parent_name_extractor: "organizations/{organization}"
+// }
+// name_descriptor: {
+// pattern: "billingAccounts/{billing_account}/logs/{log}"
+// parent_type: "billing.googleapis.com/BillingAccount"
+// parent_name_extractor: "billingAccounts/{billing_account}"
+// }
+// };
+// }
+//
+// The ResourceDescriptor Yaml config will look like:
+//
+// resources:
+// - type: 'logging.googleapis.com/LogEntry'
+// name_descriptor:
+// - pattern: "projects/{project}/logs/{log}"
+// parent_type: "cloudresourcemanager.googleapis.com/Project"
+// parent_name_extractor: "projects/{project}"
+// - pattern: "folders/{folder}/logs/{log}"
+// parent_type: "cloudresourcemanager.googleapis.com/Folder"

+// - pattern: "organizations/{organization}/logs/{log}"
+// parent_type: "cloudresourcemanager.googleapis.com/Organization"

+// - pattern: "billingAccounts/{billing_account}/logs/{log}"
+// parent_type: "billing.googleapis.com/BillingAccount"
+// parent_name_extractor: "billingAccounts/{billing_account}"
+//
+// For flexible resources, the resource name doesn't contain parent names, but
+// the resource itself has parents for policy evaluation.
+//
+// Example:
+//
+// message Shelf {
+// option (google.api.resource) = {
+// type: "library.googleapis.com/Shelf"

+# How to contribute
+
+We definitely welcome your patches and contributions to gRPC! Please read the gRPC
+organization's [governance rules](https://github.com/grpc/grpc-community/blob/master/governance.md)
+and [contribution guidelines](https://github.com/grpc/grpc-community/blob/master/CONTRIBUTING.md) before proceeding.
+
+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.
+
+- 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](https://godoc.org/google.golang.org/grpc?imports), you need a
+ discussion with gRPC-Go authors and consultants.
+
+- 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

+ 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

+# gRPC-Go
+
+[](https://travis-ci.org/grpc/grpc-go)
+[][API]
+[](https://goreportcard.com/report/github.com/grpc/grpc-go)
+
+The [Go][] implementation of [gRPC][]: A high performance, open source, general
+RPC framework that puts mobile and HTTP/2 first. For more information see the
+[Go gRPC docs][], or jump directly into the [quick start][].
+
+## Prerequisites
+
+- **[Go][]**: any one of the **three latest major** [releases][go-releases].
+
+## Installation
+
+With [Go module][] support (Go 1.11+), simply add the following import
+
+```go
+import "google.golang.org/grpc"
+```
+
+to your code, and then `go [build|run|test]` will automatically fetch the
+necessary dependencies.
+
+Otherwise, to install the `grpc-go` package, run the following command:
+
+```console
+$ go get -u google.golang.org/grpc
+```
+
+> **Note:** If you are trying to access `grpc-go` from **China**, see the
+> [FAQ](#FAQ) below.
+
+## Learn more
+
+- [Go gRPC docs][], which include a [quick start][] and [API
+ reference][API] among other resources
+- [Low-level technical docs](Documentation) from this repository
+- [Performance benchmark][]
+- [Examples](examples)
+
+## FAQ
+
+### I/O Timeout Errors
+
+The `golang.org` domain may be blocked from some countries. `go get` usually
+produces an error like the following when this happens:
+
+```console
+$ go get -u google.golang.org/grpc
+package google.golang.org/grpc: unrecognized import path "google.golang.org/grpc" (https fetch: Get https://google.golang.org/grpc?go-get=1: dial tcp 216.239.37.1:443: i/o timeout)
+```
+
+To build Go code, there are several options:
+
+- Set up a VPN and access google.golang.org through that.
+
+- Without Go module support: `git clone` the repo manually:
+
+ ```sh
+ git clone https://github.com/grpc/grpc-go.git $GOPATH/src/google.golang.org/grpc
+ ```
+
+ You will need to do the same for all of grpc's dependencies in `golang.org`,
+ e.g. `golang.org/x/net`.
+
+- With Go module support: it is possible to use the `replace` feature of `go
+ mod` to create aliases for golang.org packages. In your project's directory:
+
+ ```sh
+ go mod edit -replace=google.golang.org/grpc=github.com/grpc/grpc-go@latest
+ go mod tidy
+ go mod vendor
+ go build -mod=vendor
+ ```
+
+ Again, this will need to be done for all transitive dependencies hosted on
+ golang.org as well. For details, refer to [golang/go issue #28652](https://github.com/golang/go/issues/28652).
+
+### Compiling error, undefined: grpc.SupportPackageIsVersion
+
+#### If you are using Go modules:
+
+Ensure your gRPC-Go version is `require`d at the appropriate version in
+the same module containing the generated `.pb.go` files. For example,
+`SupportPackageIsVersion6` needs `v1.27.0`, so in your `go.mod` file:
+
+```go
+module <your module name>
+
+require (
+ google.golang.org/grpc v1.27.0
+)
+```
+
+#### If you are *not* using Go modules:
+
+Update the `proto` package, gRPC package, and rebuild the `.proto` files:
+
+```sh
+go get -u github.com/golang/protobuf/{proto,protoc-gen-go}
+go get -u google.golang.org/grpc
+protoc --go_out=plugins=grpc:. *.proto
+```
+
+### How to turn on logging
+
+The default logger is controlled by environment variables. Turn everything on
+like this:
+
+```console
+$ export GRPC_GO_LOG_VERBOSITY_LEVEL=99
+$ export 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
+ 1. Keepalive parameters caused connection shutdown, for example if you have configured
+ your server to terminate connections regularly to [trigger DNS lookups](https://github.com/grpc/grpc-go/issues/3170#issuecomment-552517779).
+ If this is the case, you may want to increase your [MaxConnectionAgeGrace](https://pkg.go.dev/google.golang.org/grpc/keepalive?tab=doc#ServerParameters),
+ to allow longer RPC calls to finish.
+
+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.

+// for m in md.Messages: yield m
+// for x in md.Extensions: yield x
+// for m in md.Messages: yield from VisitMessageDecls(m)

+// Binary serialization
+//
+// This package contains functions to convert to and from the wire format,
+// an efficient binary serialization of protocol buffers.
+//
+// • Size reports the size of a message in the wire format.
+//
+// • Marshal converts a message to the wire format.
+// The MarshalOptions type provides more control over wire marshaling.
+//
+// • Unmarshal converts a message from the wire format.
+// The UnmarshalOptions type provides more control over wire unmarshaling.
+//
+//
+// Basic message operations
+//
+// • Clone makes a deep copy of a message.
+//
+// • Merge merges the content of a message into another.
+//
+// • Equal compares two messages. For more control over comparisons
+// and detailed reporting of differences, see package
+// "google.golang.org/protobuf/testing/protocmp".
+//
+// • Reset clears the content of a message.
+//
+// • CheckInitialized reports whether all required fields in a message are set.
+//
+//
+// Optional scalar constructors
+//
+// The API for some generated messages represents optional scalar fields
+// as pointers to a value. For example, an optional string field has the
+// Go type *string.
+//
+// • Bool, Int32, Int64, Uint32, Uint64, Float32, Float64, and String
+// take a value and return a pointer to a new instance of it,
+// to simplify construction of optional field values.
+//
+// Generated enum types usually have an Enum method which performs the
+// same operation.
+//
+// Optional scalar fields are only supported in proto2.
+//
+//
+// Extension accessors
+//
+// • HasExtension, GetExtension, SetExtension, and ClearExtension
+// access extension field values in a protocol buffer message.
+//
+// Extension fields are only supported in proto2.
+//
+//
+// Related packages
+//
+// • Package "google.golang.org/protobuf/encoding/protojson" converts messages to
+// and from JSON.
+//
+// • Package "google.golang.org/protobuf/encoding/prototext" converts messages to
+// and from the text format.
+//
+// • Package "google.golang.org/protobuf/reflect/protoreflect" provides a
+// reflection interface for protocol buffer data types.
+//
+// • Package "google.golang.org/protobuf/testing/protocmp" provides features
+// to compare protocol buffer messages with the "github.com/google/go-cmp/cmp"
+// package.
+//
+// • Package "google.golang.org/protobuf/types/dynamicpb" provides a dynamic
+// message type, suitable for working with messages where the protocol buffer
+// type is only known at runtime.
+//
+// This module contains additional packages for more specialized use cases.

+// Package protoreflect provides interfaces to dynamically manipulate messages.
+//
+// This package includes type descriptors which describe the structure of types
+// defined in proto source files and value interfaces which provide the
+// ability to examine and manipulate the contents of messages.
+//
+//
+// Protocol Buffer Descriptors
+//
+// Protobuf descriptors (e.g., EnumDescriptor or MessageDescriptor)
+// are immutable objects that represent protobuf type information.
+// They are wrappers around the messages declared in descriptor.proto.
+// Protobuf descriptors alone lack any information regarding Go types.
+//
+// Enums and messages generated by this module implement Enum and ProtoMessage,
+// where the Descriptor and ProtoReflect.Descriptor accessors respectively
+// return the protobuf descriptor for the values.
+//
+// The protobuf descriptor interfaces are not meant to be implemented by
+// user code since they might need to be extended in the future to support
+// additions to the protobuf language.
+// The "google.golang.org/protobuf/reflect/protodesc" package converts between
+// google.protobuf.DescriptorProto messages and protobuf descriptors.
+//
+//
+// Go Type Descriptors
+//
+// A type descriptor (e.g., EnumType or MessageType) is a constructor for
+// a concrete Go type that represents the associated protobuf descriptor.
+// There is commonly a one-to-one relationship between protobuf descriptors and
+// Go type descriptors, but it can potentially be a one-to-many relationship.
+//
+// Enums and messages generated by this module implement Enum and ProtoMessage,
+// where the Type and ProtoReflect.Type accessors respectively
+// return the protobuf descriptor for the values.
+//
+// The "google.golang.org/protobuf/types/dynamicpb" package can be used to
+// create Go type descriptors from protobuf descriptors.
+//
+//
+// Value Interfaces
+//
+// The Enum and Message interfaces provide a reflective view over an
+// enum or message instance. For enums, it provides the ability to retrieve
+// the enum value number for any concrete enum type. For messages, it provides
+// the ability to access or manipulate fields of the message.
+//
+// To convert a proto.Message to a protoreflect.Message, use the
+// former's ProtoReflect method. Since the ProtoReflect method is new to the
+// v2 message interface, it may not be present on older message implementations.
+// The "github.com/golang/protobuf/proto".MessageReflect function can be used
+// to obtain a reflective view on older messages.
+//
+//
+// Relationships
+//
+// The following diagrams demonstrate the relationships between
+// various types declared in this package.

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

+ // the root FileDescriptorProto to the place where the definition. For
+ // example, this path:
+ // [ 4, 3, 2, 7, 1 ]
+ // refers to:
+ // file.message_type(3) // 4, 3
+ // .field(7) // 2, 7
+ // .name() // 1
+ // This is because FileDescriptorProto.message_type has field number 4:
+ // repeated DescriptorProto message_type = 4;
+ // and DescriptorProto.field has field number 2:
+ // repeated FieldDescriptorProto field = 2;
+ // and FieldDescriptorProto.name has field number 1:
+ // optional string name = 1;
+ //
+ // Thus, the above path gives the location of a field name. If we removed
+ // the last element:
+ // [ 4, 3, 2, 7 ]
+ // this path refers to the whole field declaration (from the beginning
+ // of the label to the terminating semicolon).

+ // and column numbers are zero-based -- typically you will want to add
+ // 1 to each before displaying to a user.

+ // A series of line comments appearing on consecutive lines, with no other

+ //
+ // leading_detached_comments will keep paragraphs of comments that appear

+ // separated by empty lines, will be one comment element in the repeated
+ // field.

+ // Only the comment content is provided; comment markers (e.g. //) are

+ // optional string baz = 3;

+
+// Package anypb contains generated types for google/protobuf/any.proto.
+//
+// The Any message is a dynamic representation of any other message value.
+// It is functionally a tuple of the full name of the remote message type and
+// the serialized bytes of the remote message value.
+//
+//
+// Constructing an Any
+//
+// An Any message containing another message value is constructed using New:
+//
+// any, err := anypb.New(m)
+// if err != nil {
+// ... // handle error
+// }
+// ... // make use of any
+//
+//
+// Unmarshaling an Any
+//
+// With a populated Any message, the underlying message can be serialized into
+// a remote concrete message value in a few ways.
+//
+// If the exact concrete type is known, then a new (or pre-existing) instance
+// of that message can be passed to the UnmarshalTo method:
+//
+// m := new(foopb.MyMessage)
+// if err := any.UnmarshalTo(m); err != nil {
+// ... // handle error
+// }
+// ... // make use of m
+//
+// If the exact concrete type is not known, then the UnmarshalNew method can be
+// used to unmarshal the contents into a new instance of the remote message type:
+//
+// m, err := any.UnmarshalNew()
+// if err != nil {
+// ... // handle error
+// }
+// ... // make use of m
+//
+// UnmarshalNew uses the global type registry to resolve the message type and
+// construct a new instance of that message to unmarshal into. In order for a
+// message type to appear in the global registry, the Go type representing that
+// protobuf message type must be linked into the Go binary. For messages
+// generated by protoc-gen-go, this is achieved through an import of the
+// generated Go package representing a .proto file.
+//
+// A common pattern with UnmarshalNew is to use a type switch with the resulting
+// proto.Message value:
+//
+// switch m := m.(type) {
+// case *foopb.MyMessage:
+// ... // make use of m as a *foopb.MyMessage
+// case *barpb.OtherMessage:
+// ... // make use of m as a *barpb.OtherMessage
+// case *bazpb.SomeMessage:
+// ... // make use of m as a *bazpb.SomeMessage
+// }
+//
+// This pattern ensures that the generated packages containing the message types
+// listed in the case clauses are linked into the Go binary and therefore also
+// registered in the global registry.
+//
+//
+// Type checking an Any
+//
+// In order to type check whether an Any message represents some other message,
+// then use the MessageIs method:
+//
+// if any.MessageIs((*foopb.MyMessage)(nil)) {
+// ... // make use of any, knowing that it contains a foopb.MyMessage
+// }
+//
+// The MessageIs method can also be used with an allocated instance of the target
+// message type if the intention is to unmarshal into it if the type matches:
+//
+// m := new(foopb.MyMessage)
+// if any.MessageIs(m) {
+// if err := any.UnmarshalTo(m); err != nil {
+// ... // handle error
+// }
+// ... // make use of m
+// }

+// `Any` contains an arbitrary serialized protocol buffer message along with a
+// URL that describes the type of the serialized message.
+//
+// Protobuf library provides support to pack/unpack Any values in the form
+// of utility functions or additional generated methods of the Any type.
+//
+// Example 1: Pack and unpack a message in C++.
+//
+// Foo foo = ...;
+// Any any;
+// any.PackFrom(foo);
+// ...
+// if (any.UnpackTo(&foo)) {
+// ...
+// }
+//
+// Example 2: Pack and unpack a message in Java.
+//
+// Foo foo = ...;
+// Any any = Any.pack(foo);
+// ...
+// if (any.is(Foo.class)) {
+// foo = any.unpack(Foo.class);
+// }
+//
+// Example 3: Pack and unpack a message in Python.
+//
+// foo = Foo(...)
+// any = Any()
+// any.Pack(foo)
+// ...
+// if any.Is(Foo.DESCRIPTOR):
+// any.Unpack(foo)
+// ...
+//
+// Example 4: Pack and unpack a message in Go
+//
+// foo := &pb.Foo{...}
+// any, err := anypb.New(foo)
+// if err != nil {
+// ...
+// }
+// ...
+// foo := &pb.Foo{}
+// if err := any.UnmarshalTo(foo); err != nil {
+// ...
+// }
+//
+// The pack methods provided by protobuf library will by default use
+// 'type.googleapis.com/full.type.name' as the type URL and the unpack
+// methods only use the fully qualified type name after the last '/'
+// in the type URL, for example "foo.bar.com/x/y.z" will yield type
+// name "y.z".
+//
+//
+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+// package google.profile;
+// message Person {
+// string first_name = 1;
+// string last_name = 2;
+// }
+//
+// {
+// "@type": "type.googleapis.com/google.profile.Person",
+// "firstName": <string>,
+// "lastName": <string>
+// }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+// {
+// "@type": "type.googleapis.com/google.protobuf.Duration",
+// "value": "1.212s"
+// }
+//
+type Any struct {
+ state protoimpl.MessageState
+ sizeCache protoimpl.SizeCache
+ unknownFields protoimpl.UnknownFields
+
+ // A URL/resource name that uniquely identifies the type of the serialized
+ // protocol buffer message. This string must contain at least
+ // one "/" character. The last segment of the URL's path must represent
+ // the fully qualified name of the type (as in
+ // `path/google.protobuf.Duration`). The name should be in a canonical form
+ // (e.g., leading "." is not accepted).
+ //
+ // In practice, teams usually precompile into the binary all types that they
+ // expect it to use in the context of Any. However, for URLs which use the
+ // scheme `http`, `https`, or no scheme, one can optionally set up a type
+ // server that maps type URLs to message definitions as follows:
+ //
+ // * If no scheme is provided, `https` is assumed.
+ // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+ // value in binary format, or produce an error.
+ // * Applications are allowed to cache lookup results based on the
+ // URL, or have them precompiled into a binary to avoid any
+ // lookup. Therefore, binary compatibility needs to be preserved
+ // on changes to types. (Use versioned type names to manage
+ // breaking changes.)
+ //
+ // Note: this functionality is not currently available in the official
+ // protobuf release, and it is not used for type URLs beginning with

+// The Duration message represents a signed span of time.

+//
+// Conversion to a Go Duration
+//
+// The AsDuration method can be used to convert a Duration message to a
+// standard Go time.Duration value:
+//
+// d := dur.AsDuration()
+// ... // make use of d as a time.Duration
+//
+// Converting to a time.Duration is a common operation so that the extensive
+// set of time-based operations provided by the time package can be leveraged.
+// See https://golang.org/pkg/time for more information.
+//
+// The AsDuration method performs the conversion on a best-effort basis.
+// Durations with denormal values (e.g., nanoseconds beyond -99999999 and
+// +99999999, inclusive; or seconds and nanoseconds with opposite signs)
+// are normalized during the conversion to a time.Duration. To manually check for
+// invalid Duration per the documented limitations in duration.proto,
+// additionally call the CheckValid method:
+//
+// if err := dur.CheckValid(); err != nil {
+// ... // handle error
+// }
+//
+// Note that the documented limitations in duration.proto does not protect a
+// Duration from overflowing the representable range of a time.Duration in Go.
+// The AsDuration method uses saturation arithmetic such that an overflow clamps
+// the resulting value to the closest representable value (e.g., math.MaxInt64
+// for positive overflow and math.MinInt64 for negative overflow).
+//
+//
+// Conversion from a Go Duration
+//

+// The Timestamp message represents a timestamp,
+// an instant in time since the Unix epoch (January 1st, 1970).
+//
+//
+// Conversion to a Go Time
+//
+// The AsTime method can be used to convert a Timestamp message to a
+// standard Go time.Time value in UTC:
+//
+// t := ts.AsTime()
+// ... // make use of t as a time.Time
+//
+// Converting to a time.Time is a common operation so that the extensive
+// set of time-based operations provided by the time package can be leveraged.
+// See https://golang.org/pkg/time for more information.
+//
+// The AsTime method performs the conversion on a best-effort basis. Timestamps
+// with denormal values (e.g., nanoseconds beyond 0 and 99999999, inclusive)
+// are normalized during the conversion to a time.Time. To manually check for
+// invalid Timestamps per the documented limitations in timestamp.proto,
+// additionally call the CheckValid method:
+//
+// if err := ts.CheckValid(); err != nil {
+// ... // handle error
+// }
+//
+//
+// Conversion from a Go Time
+//
+// The timestamppb.New function can be used to construct a Timestamp message
+// from a standard Go time.Time value:
+//
+// ts := timestamppb.New(t)
+// ... // make use of ts as a *timestamppb.Timestamp
+//
+// In order to construct a Timestamp representing the current time, use Now:
+//
+// ts := timestamppb.Now()
+// ... // make use of ts as a *timestamppb.Timestamp
+//

+// A Timestamp represents a point in time independent of any time zone or local
+// calendar, encoded as a count of seconds and fractions of seconds at
+// nanosecond resolution. The count is relative to an epoch at UTC midnight on
+// January 1, 1970, in the proleptic Gregorian calendar which extends the
+// Gregorian calendar backwards to year one.
+//
+// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
+// second table is needed for interpretation, using a [24-hour linear
+// smear](https://developers.google.com/time/smear).
+//
+// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
+// restricting to that range, we ensure that we can convert to and from [RFC
+// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
+//
+// # Examples
+//
+// Example 1: Compute Timestamp from POSIX `time()`.
+//
+// Timestamp timestamp;
+// timestamp.set_seconds(time(NULL));
+// timestamp.set_nanos(0);
+//
+// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+//
+// struct timeval tv;
+// gettimeofday(&tv, NULL);
+//
+// Timestamp timestamp;
+// timestamp.set_seconds(tv.tv_sec);
+// timestamp.set_nanos(tv.tv_usec * 1000);
+//
+// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+//
+// FILETIME ft;
+// GetSystemTimeAsFileTime(&ft);
+// UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+//
+// // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+// // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+// Timestamp timestamp;
+// timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+// timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+//
+// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+//
+// long millis = System.currentTimeMillis();
+//
+// Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+// .setNanos((int) ((millis % 1000) * 1000000)).build();
+//
+//
+// Example 5: Compute Timestamp from Java `Instant.now()`.
+//
+// Instant now = Instant.now();
+//
+// Timestamp timestamp =
+// Timestamp.newBuilder().setSeconds(now.getEpochSecond())
+// .setNanos(now.getNano()).build();
+//
+//
+// Example 6: Compute Timestamp from current time in Python.
+//
+// timestamp = Timestamp()
+// timestamp.GetCurrentTime()
+//
+// # JSON Mapping
+//
+// In JSON format, the Timestamp type is encoded as a string in the
+// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+// where {year} is always expressed using four digits while {month}, {day},
+// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+// is required. A proto3 JSON serializer should always use UTC (as indicated by
+// "Z") when printing the Timestamp type and a proto3 JSON parser should be
+// able to accept both UTC and other timezones (as indicated by an offset).
+//
+// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+// 01:30 UTC on January 15, 2017.
+//
+// In JavaScript, one can convert a Date object to this format using the
+// standard
+// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+// method. In Python, a standard `datetime.datetime` object can be converted
+// to this format using
+// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
+// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
+// the Joda Time's [`ISODateTimeFormat.dateTime()`](
+// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
+// ) to obtain a formatter capable of generating timestamps in this format.
