Package cloud is the root of the packages used to access Google Cloud
Services. See https://godoc.org/cloud.google.com/go for a full list
of sub-packages.
Client Options
All clients in sub-packages are configurable via client options. These options are
described here: https://godoc.org/google.golang.org/api/option.
Authentication and Authorization
All the clients in sub-packages support authentication via Google Application Default
Credentials (see https://cloud.google.com/docs/authentication/production), or
by providing a JSON key file for a Service Account. See the authentication examples
in this package for details.
Timeouts and Cancellation
By default, all requests in sub-packages will run indefinitely, retrying on transient
errors when correctness allows. To set timeouts or arrange for cancellation, use
contexts. See the examples for details.
Do not attempt to control the initial connection (dialing) of a service by setting a
timeout on the context passed to NewClient. Dialing is non-blocking, so timeouts
would be ineffective and would only interfere with credential refreshing, which uses
the same context.
Connection Pooling
Connection pooling differs in clients based on their transport. Cloud
clients either rely on HTTP or gRPC transports to communicate
with Google Cloud.
Cloud clients that use HTTP (bigquery, compute, storage, and translate) rely on the
underlying HTTP transport to cache connections for later re-use. These are cached to
the default http.MaxIdleConns and http.MaxIdleConnsPerHost settings in
http.DefaultTransport.
For gRPC clients (all others in this repo), connection pooling is configurable. Users
of cloud client libraries may specify option.WithGRPCConnectionPool(n) as a client
option to NewClient calls. This configures the underlying gRPC connections to be
pooled and addressed in a round robin fashion.
Using the Libraries with Docker
Minimal docker images like Alpine lack CA certificates. This causes RPCs to appear to
hang, because gRPC retries indefinitely. See https://github.com/googleapis/google-cloud-go/issues/928
for more information.
Debugging
To see gRPC logs, set the environment variable GRPC_GO_LOG_SEVERITY_LEVEL. See
https://godoc.org/google.golang.org/grpc/grpclog for more information.
For HTTP logging, set the GODEBUG environment variable to "http2debug=1" or "http2debug=2".
Client Stability
Clients in this repository are considered alpha or beta unless otherwise
marked as stable in the README.md. Semver is not used to communicate stability
of clients.
Alpha and beta clients may change or go away without notice.
Clients marked stable will maintain compatibility with future versions for as
long as we can reasonably sustain. Incompatible changes might be made in some
situations, including:
- Security bugs may prompt backwards-incompatible changes.
- Situations in which components are no longer feasible to maintain without
making breaking changes, including removal.
- Parts of the client surface may be outright unstable and subject to change.
These parts of the surface will be labeled with the note, "It is EXPERIMENTAL
and subject to change or removal without notice."

## Stackdriver Logging [![GoDoc](https://godoc.org/cloud.google.com/go/logging?status.svg)](https://godoc.org/cloud.google.com/go/logging)
- [About Stackdriver Logging](https://cloud.google.com/logging/)
- [API documentation](https://cloud.google.com/logging/docs)
- [Go client documentation](https://godoc.org/cloud.google.com/go/logging)
- [Complete sample programs](https://github.com/GoogleCloudPlatform/golang-samples/tree/master/logging)
### Example Usage
First create a `logging.Client` to use throughout your application:
[snip]:# (logging-1)
```go
ctx := context.Background()
client, err := logging.NewClient(ctx, "my-project")
if err != nil {
// TODO: Handle error.
}
```
Usually, you'll want to add log entries to a buffer to be periodically flushed
(automatically and asynchronously) to the Stackdriver Logging service.
[snip]:# (logging-2)
```go
logger := client.Logger("my-log")
logger.Log(logging.Entry{Payload: "something happened!"})
```
Close your client before your program exits, to flush any buffered log entries.
[snip]:# (logging-3)
```go
err = client.Close()
if err != nil {
// TODO: Handle error.
}
```

Grouping Logs by Request
To group all the log entries written during a single HTTP request, create two
Loggers, a "parent" and a "child," with different log IDs. Both should be in the same
project, and have the same MonitoredResouce type and labels.
- Parent entries must have HTTPRequest.Request populated. (Strictly speaking, only the URL is necessary.)
- A child entry's timestamp must be within the time interval covered by the parent request (i.e., older
than parent.Timestamp, and newer than parent.Timestamp - parent.HTTPRequest.Latency, assuming the
parent timestamp marks the end of the request.
- The trace field must be populated in all of the entries and match exactly.
You should observe the child log entries grouped under the parent on the console. The
parent entry will not inherit the severity of its children; you must update the
parent severity yourself.

Name *string `protobuf:"bytes,1,opt,name=name" json:"name,omitempty"`
// If non-empty, indicates that the named file should already exist, and the
// content here is to be inserted into that file at a defined insertion
// point. This feature allows a code generator to extend the output
// produced by another code generator. The original generator may provide
// insertion points by placing special annotations in the file that look
// like:
// @@protoc_insertion_point(NAME)
// The annotation can have arbitrary text before and after it on the line,
// which allows it to be placed in a comment. NAME should be replaced with
// an identifier naming the point -- this is what other generators will use
// as the insertion_point. Code inserted at this point will be placed
// immediately above the line containing the insertion point (thus multiple
// insertions to the same point will come out in the order they were added).
// The double-@ is intended to make it unlikely that the generated code
// could contain things that look like insertion points by accident.
//
// For example, the C++ code generator places the following line in the
// .pb.h files that it generates:
// // @@protoc_insertion_point(namespace_scope)
// This line appears within the scope of the file's package namespace, but
// outside of any particular class. Another plugin can then specify the
// insertion_point "namespace_scope" to generate additional classes or
// other declarations that should be placed in this scope.
//
// Note that if the line containing the insertion point begins with
// whitespace, the same whitespace will be added to every line of the
// inserted text. This is useful for languages like Python, where
// indentation matters. In these languages, the insertion point comment
// should be indented the same amount as any inserted code will need to be
// in order to work correctly in that context.
//
// The code generator that generates the initial file and the one which
// inserts into it must both run as part of a single invocation of protoc.
// Code generators are executed in the order in which they appear on the
// command line.
//
// If |insertion_point| is present, |name| must also be present.

// insertion points by placing special annotations in the file that look
// like:
// @@protoc_insertion_point(NAME)
// The annotation can have arbitrary text before and after it on the line,
// which allows it to be placed in a comment. NAME should be replaced with
// an identifier naming the point -- this is what other generators will use
// as the insertion_point. Code inserted at this point will be placed
// immediately above the line containing the insertion point (thus multiple
// insertions to the same point will come out in the order they were added).
// The double-@ is intended to make it unlikely that the generated code
// could contain things that look like insertion points by accident.
//
// For example, the C++ code generator places the following line in the
// .pb.h files that it generates:
// // @@protoc_insertion_point(namespace_scope)
// This line appears within the scope of the file's package namespace, but
// outside of any particular class. Another plugin can then specify the
// insertion_point "namespace_scope" to generate additional classes or
// other declarations that should be placed in this scope.
//
// Note that if the line containing the insertion point begins with
// whitespace, the same whitespace will be added to every line of the
// inserted text. This is useful for languages like Python, where
// indentation matters. In these languages, the insertion point comment
// should be indented the same amount as any inserted code will need to be
// in order to work correctly in that context.
//
// The code generator that generates the initial file and the one which
// inserts into it must both run as part of a single invocation of protoc.
// Code generators are executed in the order in which they appear on the
// command line.
//
// If |insertion_point| is present, |name| must also be present.

Google API Extensions for Go
============================
[![Build Status](https://travis-ci.org/googleapis/gax-go.svg?branch=master)](https://travis-ci.org/googleapis/gax-go)
[![Code Coverage](https://img.shields.io/codecov/c/github/googleapis/gax-go.svg)](https://codecov.io/github/googleapis/gax-go)
[![GoDoc](https://godoc.org/github.com/googleapis/gax-go?status.svg)](https://godoc.org/github.com/googleapis/gax-go)
Google API Extensions for Go (gax-go) is a set of modules which aids the
development of APIs for clients and servers based on `gRPC` and Google API
conventions.
Application code will rarely need to use this library directly,
To install the API extensions, use:
```
go get -u github.com/googleapis/gax-go
```
**Note:** Application code will rarely need to use this library directly,
but the code generated automatically from API definition files can use it
to simplify code generation and to provide more convenient and idiomatic API surface.
**This project is currently experimental and not supported.**
Go Versions
===========
This library requires Go 1.6 or above.

# Go Tools
This subrepository holds the source for various packages and tools that support
the Go programming language.
Some of the tools, `godoc` and `vet` for example, are included in binary Go
distributions.
Others, including the Go `guru` and the test coverage tool, can be fetched with
`go get`.
Packages include a type-checker for Go and an implementation of the
Static Single Assignment form (SSA) representation for Go programs.
## Download/Install
The easiest way to install is to run `go get -u golang.org/x/tools/...`. You can
also manually git clone the repository to `$GOPATH/src/golang.org/x/tools`.
## Report Issues / Send Patches
This repository uses Gerrit for code changes. To learn how to submit changes to
this repository, see https://golang.org/doc/contribute.html.
The main issue tracker for the tools repository is located at
https://github.com/golang/go/issues. Prefix your issue with "x/tools/(your
subdir):" in the subject line, so it is easy to find.
