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.

/*
Package storage provides an easy way to work with Google Cloud Storage.
Google Cloud Storage stores data in named objects, which are grouped into buckets.
More information about Google Cloud Storage is available at
https://cloud.google.com/storage/docs.
All of the methods of this package use exponential backoff to retry calls
that fail with certain errors, as described in
https://cloud.google.com/storage/docs/exponential-backoff.
Creating a Client
To start working with this package, create a client:
ctx := context.Background()
client, err := storage.NewClient(ctx)
if err != nil {
// TODO: Handle error.
}
The client will use your default application credentials.
If you only wish to access public data, you can create
an unauthenticated client with
client, err := storage.NewClient(ctx, option.WithoutAuthentication())
Buckets
A Google Cloud Storage bucket is a collection of objects. To work with a
bucket, make a bucket handle:
bkt := client.Bucket(bucketName)
A handle is a reference to a bucket. You can have a handle even if the
bucket doesn't exist yet. To create a bucket in Google Cloud Storage,
call Create on the handle:
if err := bkt.Create(ctx, projectID, nil); err != nil {
// TODO: Handle error.
}
Note that although buckets are associated with projects, bucket names are
global across all projects.
Each bucket has associated metadata, represented in this package by
BucketAttrs. The third argument to BucketHandle.Create allows you to set
the intial BucketAttrs of a bucket. To retrieve a bucket's attributes, use
Attrs:
attrs, err := bkt.Attrs(ctx)
if err != nil {
// TODO: Handle error.
}
fmt.Printf("bucket %s, created at %s, is located in %s with storage class %s\n",
attrs.Name, attrs.Created, attrs.Location, attrs.StorageClass)
Objects
An object holds arbitrary data as a sequence of bytes, like a file. You
refer to objects using a handle, just as with buckets. You can use the
standard Go io.Reader and io.Writer interfaces to read and write
object data:
obj := bkt.Object("data")
// Write something to obj.
// w implements io.Writer.
w := obj.NewWriter(ctx)
// Write some text to obj. This will overwrite whatever is there.
if _, err := fmt.Fprintf(w, "This object contains text.\n"); err != nil {
// TODO: Handle error.
}
// Close, just like writing a file.
if err := w.Close(); err != nil {
// TODO: Handle error.
}
// Read it back.
r, err := obj.NewReader(ctx)
if err != nil {
// TODO: Handle error.
}
defer r.Close()
if _, err := io.Copy(os.Stdout, r); err != nil {
// TODO: Handle error.
}
// Prints "This object contains text."
Objects also have attributes, which you can fetch with Attrs:
objAttrs, err := obj.Attrs(ctx)
if err != nil {
// TODO: Handle error.
}
fmt.Printf("object %s has size %d and can be read using %s\n",
objAttrs.Name, objAttrs.Size, objAttrs.MediaLink)
ACLs
Both objects and buckets have ACLs (Access Control Lists). An ACL is a list of
ACLRules, each of which specifies the role of a user, group or project. ACLs
are suitable for fine-grained control, but you may prefer using IAM to control
access at the project level (see
https://cloud.google.com/storage/docs/access-control/iam).
To list the ACLs of a bucket or object, obtain an ACLHandle and call its List method:
acls, err := obj.ACL().List(ctx)
if err != nil {
// TODO: Handle error.
}
for _, rule := range acls {
fmt.Printf("%s has role %s\n", rule.Entity, rule.Role)
}
You can also set and delete ACLs.
Conditions
Every object has a generation and a metageneration. The generation changes
whenever the content changes, and the metageneration changes whenever the
metadata changes. Conditions let you check these values before an operation;
the operation only executes if the conditions match. You can use conditions to
prevent race conditions in read-modify-write operations.
For example, say you've read an object's metadata into objAttrs. Now
you want to write to that object, but only if its contents haven't changed
since you read it. Here is how to express that:
w = obj.If(storage.Conditions{GenerationMatch: objAttrs.Generation}).NewWriter(ctx)
// Proceed with writing as above.
Signed URLs
You can obtain a URL that lets anyone read or write an object for a limited time.
You don't need to create a client to do this. See the documentation of
SignedURL for details.
url, err := storage.SignedURL(bucketName, "shared-object", opts)
if err != nil {
// TODO: Handle error.
}
fmt.Println(url)
Authentication
See examples of authorization and authentication at
https://godoc.org/cloud.google.com/go#pkg-examples.

# Azure Storage SDK for Go
The `github.com/Azure/azure-sdk-for-go/storage` package is used to perform REST operations against the [Azure Storage Service](https://docs.microsoft.com/en-us/azure/storage/). To manage your storage accounts (Azure Resource Manager / ARM), use the [github.com/Azure/azure-sdk-for-go/arm/storage](https://github.com/Azure/azure-sdk-for-go/tree/master/arm/storage) package. For your classic storage accounts (Azure Service Management / ASM), use [github.com/Azure/azure-sdk-for-go/management/storageservice](https://github.com/Azure/azure-sdk-for-go/tree/master/management/storageservice) package.
This package includes support for [Azure Storage Emulator](https://azure.microsoft.com/documentation/articles/storage-use-emulator/).
# Getting Started
1. Go get the SDK `go get -u github.com/Azure/azure-sdk-for-go/storage`
1. If you don't already have one, [create a Storage Account](https://docs.microsoft.com/en-us/azure/storage/storage-create-storage-account).
- Take note of your Azure Storage Account Name and Azure Storage Account Key. They'll both be necessary for using this library.
- This option is production ready, but can also be used for development.
1. (Optional, Windows only) Download and start the [Azure Storage Emulator](https://azure.microsoft.com/documentation/articles/storage-use-emulator/).
1. Checkout our existing [samples](https://github.com/Azure-Samples?q=Storage&language=go).
# Contributing
This project has adopted the [Microsoft Open Source Code of Conduct](https://opensource.microsoft.com/codeofconduct/). For more information see the [Code of Conduct FAQ](https://opensource.microsoft.com/codeofconduct/faq/) or contact [opencode@microsoft.com](mailto:opencode@microsoft.com) with any additional questions or comments.
When contributing, please conform to the following practices:
- Run [gofmt](https://golang.org/cmd/gofmt/) to use standard go formatting.
- Run [golint](https://github.com/golang/lint) to conform to standard naming conventions.
- Run [go vet](https://golang.org/cmd/vet/) to catch common Go mistakes.
- Use [GoASTScanner/gas](https://github.com/GoASTScanner/gas) to ensure there are no common security violations in your contribution.
- Run [go test](https://golang.org/cmd/go/#hdr-Test_packages) to catch possible bugs in the code: `go test ./storage/...`.
- This project uses HTTP recordings for testing.
- The recorder should be attached to the client before calling the functions to test and later stopped.
- If you updated an existing test, its recording might need to be updated. Run `go test ./storage/... -ow -check.f TestName` to rerecord the test.
- Important note: all HTTP requests in the recording must be unique: different bodies, headers (`User-Agent`, `Authorization` and `Date` or `x-ms-date` headers are ignored), URLs and methods. As opposed to the example above, the following test is not suitable for recording:
``` go
func (s *StorageQueueSuite) TestQueueExists(c *chk.C) {
cli := getQueueClient(c)
rec := cli.client.appendRecorder(c)
defer rec.Stop()
queue := cli.GetQueueReference(queueName(c))
ok, err := queue.Exists()
c.Assert(err, chk.IsNil)
c.Assert(ok, chk.Equals, false)
c.Assert(queue.Create(nil), chk.IsNil)
defer queue.Delete(nil)
ok, err = queue.Exists() // This is the very same request as the one 5 lines above
// The test replayer gets confused and the test fails in the last line
c.Assert(err, chk.IsNil)
c.Assert(ok, chk.Equals, true)
}
```
- On the other side, this test does not repeat requests: the URLs are different.
``` go
func (s *StorageQueueSuite) TestQueueExists(c *chk.C) {
cli := getQueueClient(c)
rec := cli.client.appendRecorder(c)
defer rec.Stop()
queue1 := cli.GetQueueReference(queueName(c, "nonexistent"))
ok, err := queue1.Exists()
c.Assert(err, chk.IsNil)
c.Assert(ok, chk.Equals, false)
queue2 := cli.GetQueueReference(queueName(c, "exisiting"))
c.Assert(queue2.Create(nil), chk.IsNil)
defer queue2.Delete(nil)
ok, err = queue2.Exists()
c.Assert(err, chk.IsNil)
c.Assert(ok, chk.Equals, true)
}
```

# Azure Active Directory library for Go
This project provides a stand alone Azure Active Directory library for Go. The code was extracted
from [go-autorest](https://github.com/Azure/go-autorest/) project, which is used as a base for
[azure-sdk-for-go](https://github.com/Azure/azure-sdk-for-go).
## Installation
```
go get -u github.com/Azure/go-autorest/autorest/adal
```
## Usage
An Active Directory application is required in order to use this library. An application can be registered in the [Azure Portal](https://portal.azure.com/) follow these [guidelines](https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-integrating-applications) or using the [Azure CLI](https://github.com/Azure/azure-cli).
### Register an Azure AD Application with secret
1. Register a new application with a `secret` credential
```
az ad app create \
--display-name example-app \
--homepage https://example-app/home \
--identifier-uris https://example-app/app \
--password secret
```
2. Create a service principal using the `Application ID` from previous step
```
az ad sp create --id "Application ID"
```
* Replace `Application ID` with `appId` from step 1.
### Register an Azure AD Application with certificate
1. Create a private key
```
openssl genrsa -out "example-app.key" 2048
```
2. Create the certificate
```
openssl req -new -key "example-app.key" -subj "/CN=example-app" -out "example-app.csr"
openssl x509 -req -in "example-app.csr" -signkey "example-app.key" -out "example-app.crt" -days 10000
```
3. Create the PKCS12 version of the certificate containing also the private key
```
openssl pkcs12 -export -out "example-app.pfx" -inkey "example-app.key" -in "example-app.crt" -passout pass:
```
4. Register a new application with the certificate content form `example-app.crt`
```
certificateContents="$(tail -n+2 "example-app.crt" | head -n-1)"
az ad app create \
--display-name example-app \
--homepage https://example-app/home \
--identifier-uris https://example-app/app \
--key-usage Verify --end-date 2018-01-01 \
--key-value "${certificateContents}"
```
5. Create a service principal using the `Application ID` from previous step
```
az ad sp create --id "APPLICATION_ID"
```
* Replace `APPLICATION_ID` with `appId` from step 4.
### Grant the necessary permissions
Azure relies on a Role-Based Access Control (RBAC) model to manage the access to resources at a fine-grained
level. There is a set of [pre-defined roles](https://docs.microsoft.com/en-us/azure/active-directory/role-based-access-built-in-roles)
which can be assigned to a service principal of an Azure AD application depending of your needs.
```
az role assignment create --assigner "SERVICE_PRINCIPAL_ID" --role "ROLE_NAME"
```
* Replace the `SERVICE_PRINCIPAL_ID` with the `appId` from previous step.
* Replace the `ROLE_NAME` with a role name of your choice.
It is also possible to define custom role definitions.
```
az role definition create --role-definition role-definition.json
```
* Check [custom roles](https://docs.microsoft.com/en-us/azure/active-directory/role-based-access-control-custom-roles) for more details regarding the content of `role-definition.json` file.
### Acquire Access Token
The common configuration used by all flows:
```Go
const activeDirectoryEndpoint = "https://login.microsoftonline.com/"
tenantID := "TENANT_ID"
oauthConfig, err := adal.NewOAuthConfig(activeDirectoryEndpoint, tenantID)
applicationID := "APPLICATION_ID"
callback := func(token adal.Token) error {
// This is called after the token is acquired
}
// The resource for which the token is acquired
resource := "https://management.core.windows.net/"
```
* Replace the `TENANT_ID` with your tenant ID.
* Replace the `APPLICATION_ID` with the value from previous section.
#### Client Credentials
```Go
applicationSecret := "APPLICATION_SECRET"
spt, err := adal.NewServicePrincipalToken(
oauthConfig,
appliationID,
applicationSecret,
resource,
callbacks...)
if err != nil {
return nil, err
}
// Acquire a new access token
err = spt.Refresh()
if (err == nil) {
token := spt.Token
}
```
* Replace the `APPLICATION_SECRET` with the `password` value from previous section.
#### Client Certificate
```Go
certificatePath := "./example-app.pfx"
certData, err := ioutil.ReadFile(certificatePath)
if err != nil {
return nil, fmt.Errorf("failed to read the certificate file (%s): %v", certificatePath, err)
}
// Get the certificate and private key from pfx file
certificate, rsaPrivateKey, err := decodePkcs12(certData, "")
if err != nil {
return nil, fmt.Errorf("failed to decode pkcs12 certificate while creating spt: %v", err)
}
spt, err := adal.NewServicePrincipalTokenFromCertificate(
oauthConfig,
applicationID,
certificate,
rsaPrivateKey,
resource,
callbacks...)
// Acquire a new access token
err = spt.Refresh()
if (err == nil) {
token := spt.Token
}
```
* Update the certificate path to point to the example-app.pfx file which was created in previous section.
#### Device Code
```Go
oauthClient := &http.Client{}
// Acquire the device code
deviceCode, err := adal.InitiateDeviceAuth(
oauthClient,
oauthConfig,
applicationID,
resource)
if err != nil {
return nil, fmt.Errorf("Failed to start device auth flow: %s", err)
}
// Display the authentication message
fmt.Println(*deviceCode.Message)
// Wait here until the user is authenticated
token, err := adal.WaitForUserCompletion(oauthClient, deviceCode)
if err != nil {
return nil, fmt.Errorf("Failed to finish device auth flow: %s", err)
}
spt, err := adal.NewServicePrincipalTokenFromManualToken(
oauthConfig,
applicationID,
resource,
*token,
callbacks...)
if (err == nil) {
token := spt.Token
}
```
#### Username password authenticate
```Go
spt, err := adal.NewServicePrincipalTokenFromUsernamePassword(
oauthConfig,
applicationID,
username,
password,
resource,
callbacks...)
if (err == nil) {
token := spt.Token
}
```
#### Authorization code authenticate
``` Go
spt, err := adal.NewServicePrincipalTokenFromAuthorizationCode(
oauthConfig,
applicationID,
clientSecret,
authorizationCode,
redirectURI,
resource,
callbacks...)
err = spt.Refresh()
if (err == nil) {
token := spt.Token
}
```
### Command Line Tool
A command line tool is available in `cmd/adal.go` that can acquire a token for a given resource. It supports all flows mentioned above.
```
adal -h
Usage of ./adal:
-applicationId string
application id
-certificatePath string
path to pk12/PFC application certificate
-mode string
authentication mode (device, secret, cert, refresh) (default "device")
-resource string
resource for which the token is requested
-secret string
application secret
-tenantId string
tenant id
-tokenCachePath string
location of oath token cache (default "/home/cgc/.adal/accessToken.json")
```
Example acquire a token for `https://management.core.windows.net/` using device code flow:
```
adal -mode device \
-applicationId "APPLICATION_ID" \
-tenantId "TENANT_ID" \
-resource https://management.core.windows.net/
```

/*
Package autorest implements an HTTP request pipeline suitable for use across multiple go-routines
and provides the shared routines relied on by AutoRest (see https://github.com/Azure/autorest/)
generated Go code.
The package breaks sending and responding to HTTP requests into three phases: Preparing, Sending,
and Responding. A typical pattern is:
req, err := Prepare(&http.Request{},
token.WithAuthorization())
resp, err := Send(req,
WithLogging(logger),
DoErrorIfStatusCode(http.StatusInternalServerError),
DoCloseIfError(),
DoRetryForAttempts(5, time.Second))
err = Respond(resp,
ByDiscardingBody(),
ByClosing())
Each phase relies on decorators to modify and / or manage processing. Decorators may first modify
and then pass the data along, pass the data first and then modify the result, or wrap themselves
around passing the data (such as a logger might do). Decorators run in the order provided. For
example, the following:
req, err := Prepare(&http.Request{},
WithBaseURL("https://microsoft.com/"),
WithPath("a"),
WithPath("b"),
WithPath("c"))
will set the URL to:
https://microsoft.com/a/b/c
Preparers and Responders may be shared and re-used (assuming the underlying decorators support
sharing and re-use). Performant use is obtained by creating one or more Preparers and Responders
shared among multiple go-routines, and a single Sender shared among multiple sending go-routines,
all bound together by means of input / output channels.
Decorators hold their passed state within a closure (such as the path components in the example
above). Be careful to share Preparers and Responders only in a context where such held state
applies. For example, it may not make sense to share a Preparer that applies a query string from a
fixed set of values. Similarly, sharing a Responder that reads the response body into a passed
struct (e.g., ByUnmarshallingJson) is likely incorrect.
Lastly, the Swagger specification (https://swagger.io) that drives AutoRest
(https://github.com/Azure/autorest/) precisely defines two date forms: date and date-time. The
github.com/Azure/go-autorest/autorest/date package provides time.Time derivations to ensure
correct parsing and formatting.
Errors raised by autorest objects and methods will conform to the autorest.Error interface.
See the included examples for more detail. For details on the suggested use of this package by
generated clients, see the Client described below.
