# Contributor Code of Conduct
As contributors and maintainers of this project,
and in the interest of fostering an open and welcoming community,
we pledge to respect all people who contribute through reporting issues,
posting feature requests, updating documentation,
submitting pull requests or patches, and other activities.
We are committed to making participation in this project
a harassment-free experience for everyone,
regardless of level of experience, gender, gender identity and expression,
sexual orientation, disability, personal appearance,
body size, race, ethnicity, age, religion, or nationality.
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery
* Personal attacks
* Trolling or insulting/derogatory comments
* Public or private harassment
* Publishing other's private information,
such as physical or electronic
addresses, without explicit permission
* Other unethical or unprofessional conduct.
Project maintainers have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct.
By adopting this Code of Conduct,
project maintainers commit themselves to fairly and consistently
applying these principles to every aspect of managing this project.
Project maintainers who do not follow or enforce the Code of Conduct
may be permanently removed from the project team.
This code of conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community.
Instances of abusive, harassing, or otherwise unacceptable behavior
may be reported by opening an issue
or contacting one or more of the project maintainers.
This Code of Conduct is adapted from the [Contributor Covenant](http://contributor-covenant.org), version 1.2.0,

Some packages can record the RPCs during integration tests to a file for
subsequent replay. To record, pass the `-record` flag to `go test`. The
recording will be saved to the _package_`.replay` file. To replay integration
tests from a saved recording, the replay file must be present, the `-short` flag
must be passed to `go test`, and the **GCLOUD_TESTS_GOLANG_ENABLE_REPLAY**

# CHANGELOG
## v10.12.0
### New Features
- Added field ServicePrincipalToken.MaxMSIRefreshAttempts to configure the maximun number of attempts to refresh an MSI token.
## v10.11.4
### Bug Fixes
- If an LRO returns http.StatusOK on the initial response with no async headers return the response body from Future.GetResult().
- If there is no "final GET URL" return an error from Future.GetResult().
## v10.11.3
### Bug Fixes
- In IMDS retry logic, if we don't receive a response don't retry.
- Renamed the retry function so it's clear it's meant for IMDS only.
- For error response bodies that aren't OData-v4 compliant stick the raw JSON in the ServiceError.Details field so the information isn't lost.
- Also add the raw HTTP response to the DetailedResponse.
- Removed superfluous wrapping of response error in azure.DoRetryWithRegistration().
## v10.11.2
### Bug Fixes
- Validation for integers handles int and int64 types.
## v10.11.1
### Bug Fixes
- Adding User information to authorization config as parsed from CLI cache.
## v10.11.0
### New Features
- Added NewServicePrincipalTokenFromManualTokenSecret for creating a new SPT using a manual token and secret
- Added method ServicePrincipalToken.MarshalTokenJSON() to marshall the inner Token
## v10.10.0
### New Features
- Most ServicePrincipalTokens can now be marshalled/unmarshall to/from JSON (ServicePrincipalCertificateSecret and ServicePrincipalMSISecret are not supported).
- Added method ServicePrincipalToken.SetRefreshCallbacks().
## v10.9.2
### Bug Fixes
- Refreshing a refresh token obtained from a web app authorization code now works.
## v10.9.1
### Bug Fixes
- The retry logic for MSI token requests now uses exponential backoff per the guidelines.
- IsTemporaryNetworkError() will return true for errors that don't implement the net.Error interface.
## v10.9.0

|Future.WaitForCompletion() | Future.WaitForCompletionRef()|
### New Features
- Added azure.NewFutureFromResponse() for creating a Future from the initial response from an async operation.
- Added Future.GetResult() for making the final GET call to retrieve the result from an async operation.
### Bug Fixes
- Some futures failed to return their results, this should now be fixed.
## v10.8.2
### Bug Fixes
- Add nil-gaurd to token retry logic.
## v10.8.1

### New Features
- Added endpoints for batch management.
## v10.1.3
### Bug Fixes
- In Client.Do() invoke WithInspection() last so that it will inspect WithAuthorization().

## Usage
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.
Package go-autorest provides an HTTP request client for use with [Autorest](https://github.com/Azure/autorest.go)-generated API client packages.
An authentication client tested with Azure Active Directory (AAD) is also
provided in this repo in the package
`github.com/Azure/go-autorest/autorest/adal`. Despite its name, this package
is maintained only as part of the Azure Go SDK and is not related to other
"ADAL" libraries in [github.com/AzureAD](https://github.com/AzureAD).
## Overview
Package go-autorest implements an HTTP request pipeline suitable for use across
multiple goroutines and provides the shared routines used by packages generated
by [Autorest](https://github.com/Azure/autorest.go).
The package breaks sending and responding to HTTP requests into three phases: Preparing, Sending,
and Responding. A typical pattern is:

# Azure Active Directory library for Go
# Azure Active Directory authentication 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).
This is a standalone package for authenticating with Azure Active
Directory from other Go libraries and applications, in particular the [Azure SDK
for Go](https://github.com/Azure/azure-sdk-for-go).
Note: Despite the package's name it is not related to other "ADAL" libraries
maintained in the [github.com/AzureAD](https://github.com/AzureAD) org. Issues
should be opened in [this repo's](https://github.com/Azure/go-autorest/issues)
or [the SDK's](https://github.com/Azure/azure-sdk-for-go/issues) issue
trackers.
## Installation
## Install
```
```bash
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).

# BTree implementation for Go
![Travis CI Build Status](https://api.travis-ci.org/google/btree.svg?branch=master)
This package provides an in-memory B-Tree implementation for Go, useful as
an ordered, mutable data structure.
The API is based off of the wonderful
http://godoc.org/github.com/petar/GoLLRB/llrb, and is meant to allow btree to
act as a drop-in replacement for gollrb trees.
See http://godoc.org/github.com/google/btree for documentation.

// Package btree implements in-memory B-Trees of arbitrary degree.
//
// btree implements an in-memory B-Tree for use as an ordered data structure.
// It is not meant for persistent storage solutions.
//
// It has a flatter structure than an equivalent red-black or other binary tree,
// which in some cases yields better memory usage and/or performance.
// See some discussion on the matter here:
// http://google-opensource.blogspot.com/2013/01/c-containers-that-save-memory-and-time.html
// Note, though, that this project is in no way related to the C++ B-Tree
// implementation written about there.
//
// Within this tree, each node contains a slice of items and a (possibly nil)
// slice of children. For basic numeric values or raw structs, this can cause
// efficiency differences when compared to equivalent C++ template code that
// stores values in arrays within the node:
// * Due to the overhead of storing values as interfaces (each
// value needs to be stored as the value itself, then 2 words for the
// interface pointing to that value and its type), resulting in higher
// memory use.
// * Since interfaces can point to values anywhere in memory, values are
// most likely not stored in contiguous blocks, resulting in a higher
// number of cache misses.
// These issues don't tend to matter, though, when working with strings or other
// heap-allocated structures, since C++-equivalent structures also must store
// pointers and also distribute their values across the heap.
//
// This implementation is designed to be a drop-in replacement to gollrb.LLRB
// trees, (http://github.com/petar/gollrb), an excellent and probably the most
// widely used ordered tree implementation in the Go ecosystem currently.
// Its functions, therefore, exactly mirror those of
// llrb.LLRB where possible. Unlike gollrb, though, we currently don't
// support storing multiple equivalent values.

httpcache
=========
[![Build Status](https://travis-ci.org/gregjones/httpcache.svg?branch=master)](https://travis-ci.org/gregjones/httpcache) [![GoDoc](https://godoc.org/github.com/gregjones/httpcache?status.svg)](https://godoc.org/github.com/gregjones/httpcache)
Package httpcache provides a http.RoundTripper implementation that works as a mostly [RFC 7234](https://tools.ietf.org/html/rfc7234) compliant cache for http responses.
It is only suitable for use as a 'private' cache (i.e. for a web-browser or an API-client and not for a shared proxy).
Cache Backends
--------------
- The built-in 'memory' cache stores responses in an in-memory map.
- [`github.com/gregjones/httpcache/diskcache`](https://github.com/gregjones/httpcache/tree/master/diskcache) provides a filesystem-backed cache using the [diskv](https://github.com/peterbourgon/diskv) library.
- [`github.com/gregjones/httpcache/memcache`](https://github.com/gregjones/httpcache/tree/master/memcache) provides memcache implementations, for both App Engine and 'normal' memcache servers.
- [`sourcegraph.com/sourcegraph/s3cache`](https://sourcegraph.com/github.com/sourcegraph/s3cache) uses Amazon S3 for storage.
- [`github.com/gregjones/httpcache/leveldbcache`](https://github.com/gregjones/httpcache/tree/master/leveldbcache) provides a filesystem-backed cache using [leveldb](https://github.com/syndtr/goleveldb/leveldb).
- [`github.com/die-net/lrucache`](https://github.com/die-net/lrucache) provides an in-memory cache that will evict least-recently used entries.
- [`github.com/die-net/lrucache/twotier`](https://github.com/die-net/lrucache/tree/master/twotier) allows caches to be combined, for example to use lrucache above with a persistent disk-cache.
- [`github.com/birkelund/boltdbcache`](https://github.com/birkelund/boltdbcache) provides a BoltDB implementation (based on the [bbolt](https://github.com/coreos/bbolt) fork).

distribute the Original Software (or portions thereof),
with or without Modifications, and/or as part of a Larger
Work; and
(b) under Patent Claims infringed by the making, using or
selling of Original Software, to make, have made, use,
practice, sell, and offer for sale, and/or otherwise
dispose of the Original Software (or portions thereof).
(c) The licenses granted in Sections 2.1(a) and (b) are
effective on the date Initial Developer first distributes
or otherwise makes the Original Software available to a
third party under the terms of this License.
(d) Notwithstanding Section 2.1(b) above, no patent license is
granted: (1) for code that You delete from the Original
Software, or (2) for infringements caused by: (i) the
modification of the Original Software, or (ii) the
combination of the Original Software with other software
or devices.
2.2. Contributor Grant.
Conditioned upon Your compliance with Section 3.1 below and
subject to third party intellectual property claims, each
Contributor hereby grants You a world-wide, royalty-free,
non-exclusive license:
(a) under intellectual property rights (other than patent or
trademark) Licensable by Contributor to use, reproduce,
modify, display, perform, sublicense and distribute the
Modifications created by such Contributor (or portions
thereof), either on an unmodified basis, with other
Modifications, as Covered Software and/or as part of a
Larger Work; and
(b) under Patent Claims infringed by the making, using, or
selling of Modifications made by that Contributor either
alone and/or in combination with its Contributor Version
(or portions of such combination), to make, use, sell,
offer for sale, have made, and/or otherwise dispose of:
(1) Modifications made by that Contributor (or portions
thereof); and (2) the combination of Modifications made by
that Contributor with its Contributor Version (or portions
of such combination).
(c) The licenses granted in Sections 2.2(a) and 2.2(b) are
effective on the date Contributor first distributes or
otherwise makes the Modifications available to a third
party.
(d) Notwithstanding Section 2.2(b) above, no patent license is
granted: (1) for any code that Contributor has deleted
from the Contributor Version; (2) for infringements caused
by: (i) third party modifications of Contributor Version,
or (ii) the combination of Modifications made by that
Contributor with other software (except as part of the
Contributor Version) or other devices; or (3) under Patent
Claims infringed by Covered Software in the absence of
Modifications made by that Contributor.
3. Distribution Obligations.
3.1. Availability of Source Code.
Any Covered Software that You distribute or otherwise make
available in Executable form must also be made available in Source
Code form and that Source Code form must be distributed only under
the terms of this License. You must include a copy of this
License with every copy of the Source Code form of the Covered
Software You distribute or otherwise make available. You must
inform recipients of any such Covered Software in Executable form
as to how they can obtain such Covered Software in Source Code
form in a reasonable manner on or through a medium customarily
used for software exchange.
3.2. Modifications.
The Modifications that You create or to which You contribute are
governed by the terms of this License. You represent that You
believe Your Modifications are Your original creation(s) and/or
You have sufficient rights to grant the rights conveyed by this
License.
3.3. Required Notices.
You must include a notice in each of Your Modifications that
identifies You as the Contributor of the Modification. You may
not remove or alter any copyright, patent or trademark notices
contained within the Covered Software, or any notices of licensing
or any descriptive text giving attribution to any Contributor or
the Initial Developer.
3.4. Application of Additional Terms.
You may not offer or impose any terms on any Covered Software in
Source Code form that alters or restricts the applicable version
of this License or the recipients' rights hereunder. You may
choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of
Covered Software. However, you may do so only on Your own behalf,
and not on behalf of the Initial Developer or any Contributor.
You must make it absolutely clear that any such warranty, support,
indemnity or liability obligation is offered by You alone, and You
hereby agree to indemnify the Initial Developer and every
Contributor for any liability incurred by the Initial Developer or
such Contributor as a result of warranty, support, indemnity or
liability terms You offer.
3.5. Distribution of Executable Versions.
You may distribute the Executable form of the Covered Software
under the terms of this License or under the terms of a license of
Your choice, which may contain terms different from this License,
provided that You are in compliance with the terms of this License
and that the license for the Executable form does not attempt to
limit or alter the recipient's rights in the Source Code form from
the rights set forth in this License. If You distribute the
Covered Software in Executable form under a different license, You
must make it absolutely clear that any terms which differ from
this License are offered by You alone, not by the Initial
Developer or Contributor. You hereby agree to indemnify the
Initial Developer and every Contributor for any liability incurred
by the Initial Developer or such Contributor as a result of any
such terms You offer.
3.6. Larger Works.
You may create a Larger Work by combining Covered Software with
other code not governed by the terms of this License and
distribute the Larger Work as a single product. In such a case,
You must make sure the requirements of this License are fulfilled
for the Covered Software.
4. Versions of the License.
4.1. New Versions.
Sun Microsystems, Inc. is the initial license steward and may
publish revised and/or new versions of this License from time to
time. Each version will be given a distinguishing version number.
Except as provided in Section 4.3, no one other than the license
steward has the right to modify this License.
4.2. Effect of New Versions.
You may always continue to use, distribute or otherwise make the
Covered Software available under the terms of the version of the
License under which You originally received the Covered Software.
If the Initial Developer includes a notice in the Original
Software prohibiting it from being distributed or otherwise made
available under any subsequent version of the License, You must
distribute and make the Covered Software available under the terms
of the version of the License under which You originally received
the Covered Software. Otherwise, You may also choose to use,
distribute or otherwise make the Covered Software available under
the terms of any subsequent version of the License published by
the license steward.
4.3. Modified Versions.
When You are an Initial Developer and You want to create a new
license for Your Original Software, You may create and use a
modified version of this License if You: (a) rename the license
and remove any references to the name of the license steward
(except to note that the license differs from this License); and
(b) otherwise make it clear that the license contains terms which
differ from this License.
5. DISCLAIMER OF WARRANTY.
COVERED SOFTWARE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS"
BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED
SOFTWARE IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR
PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE COVERED SOFTWARE IS WITH YOU. SHOULD ANY
COVERED SOFTWARE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE
INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY
NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF
WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
ANY COVERED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS
DISCLAIMER.
6. TERMINATION.
6.1. This License and the rights granted hereunder will terminate
automatically if You fail to comply with terms herein and fail to
cure such breach within 30 days of becoming aware of the breach.
Provisions which, by their nature, must remain in effect beyond
the termination of this License shall survive.
6.2. If You assert a patent infringement claim (excluding
declaratory judgment actions) against Initial Developer or a
Contributor (the Initial Developer or Contributor against whom You
assert such claim is referred to as "Participant") alleging that
the Participant Software (meaning the Contributor Version where
the Participant is a Contributor or the Original Software where
the Participant is the Initial Developer) directly or indirectly
infringes any patent, then any and all rights granted directly or
indirectly to You by such Participant, the Initial Developer (if
the Initial Developer is not the Participant) and all Contributors
under Sections 2.1 and/or 2.2 of this License shall, upon 60 days
notice from Participant terminate prospectively and automatically
at the expiration of such 60 day notice period, unless if within
such 60 day period You withdraw Your claim with respect to the
Participant Software against such Participant either unilaterally
or pursuant to a written agreement with Participant.
6.3. In the event of termination under Sections 6.1 or 6.2 above,
all end user licenses that have been validly granted by You or any
distributor hereunder prior to termination (excluding licenses
granted to You by any distributor) shall survive termination.
7. LIMITATION OF LIABILITY.
UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
(INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE
INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF
COVERED SOFTWARE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE
LIABLE TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR
CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT
LIMITATION, DAMAGES FOR LOST PROFITS, LOSS OF GOODWILL, WORK
STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL
INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT
APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO
NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR
CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY NOT
APPLY TO YOU.
8. U.S. GOVERNMENT END USERS.
The Covered Software is a "commercial item," as that term is
defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial
computer software" (as that term is defined at 48
C.F.R. 252.227-7014(a)(1)) and "commercial computer software
documentation" as such terms are used in 48 C.F.R. 12.212
(Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48
C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all
U.S. Government End Users acquire Covered Software with only those
rights set forth herein. This U.S. Government Rights clause is in
lieu of, and supersedes, any other FAR, DFAR, or other clause or
provision that addresses Government rights in computer software
under this License.
9. MISCELLANEOUS.
This License represents the complete agreement concerning subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. This License shall be governed
by the law of the jurisdiction specified in a notice contained
within the Original Software (except to the extent applicable law,
if any, provides otherwise), excluding such jurisdiction's
conflict-of-law provisions. Any litigation relating to this
License shall be subject to the jurisdiction of the courts located
in the jurisdiction and venue specified in a notice contained
within the Original Software, with the losing party responsible
for costs, including, without limitation, court costs and
reasonable attorneys' fees and expenses. The application of the
United Nations Convention on Contracts for the International Sale
of Goods is expressly excluded. Any law or regulation which
provides that the language of a contract shall be construed
against the drafter shall not apply to this License. You agree
that You alone are responsible for compliance with the United
States export administration regulations (and the export control
laws and regulation of any other countries) when You use,
distribute or otherwise make available any Covered Software.
10. RESPONSIBILITY FOR CLAIMS.
As between Initial Developer and the Contributors, each party is
responsible for claims and damages arising, directly or
indirectly, out of its utilization of rights under this License
and You agree to work with Initial Developer and Contributors to
distribute such responsibility on an equitable basis. Nothing
herein is intended or shall be deemed to constitute any admission
of liability.
--------------------------------------------------------------------
NOTICE PURSUANT TO SECTION 9 OF THE COMMON DEVELOPMENT AND
DISTRIBUTION LICENSE (CDDL)
For Covered Software in this distribution, this License shall
be governed by the laws of the State of California (excluding
conflict-of-law provisions).
Any litigation relating to this License shall be subject to the
jurisdiction of the Federal Courts of the Northern District of
California and the state courts of the State of California, with
venue lying in Santa Clara County, California.

# pty
Pty is a Go package for using unix pseudo-terminals.
## Install
go get github.com/kr/pty
## Example
### Command
```go
package main
import (
"github.com/kr/pty"
"io"
"os"
"os/exec"
)
func main() {
c := exec.Command("grep", "--color=auto", "bar")
f, err := pty.Start(c)
if err != nil {
panic(err)
}
go func() {
f.Write([]byte("foo\n"))
f.Write([]byte("bar\n"))
f.Write([]byte("baz\n"))
f.Write([]byte{4}) // EOT
}()
io.Copy(os.Stdout, f)
}
```
### Shell
```go
package main
import (
"io"
"log"
"os"
"os/exec"
"os/signal"
"syscall"
"github.com/kr/pty"
"golang.org/x/crypto/ssh/terminal"
)
func test() error {
// Create arbitrary command.
c := exec.Command("bash")
// Start the command with a pty.
ptmx, err := pty.Start(c)
if err != nil {
return err
}
// Make sure to close the pty at the end.
defer func() { _ = ptmx.Close() }() // Best effort.
// Handle pty size.
ch := make(chan os.Signal, 1)
signal.Notify(ch, syscall.SIGWINCH)
go func() {
for range ch {
if err := pty.InheritSize(os.Stdin, ptmx); err != nil {
log.Printf("error resizing pty: %s", err)
}
}
}()
ch <- syscall.SIGWINCH // Initial resize.
// Set stdin in raw mode.
oldState, err := terminal.MakeRaw(int(os.Stdin.Fd()))
if err != nil {
panic(err)
}
defer func() { _ = terminal.Restore(int(os.Stdin.Fd()), oldState) }() // Best effort.
// Copy stdin to the pty and the pty to stdout.
go func() { _, _ = io.Copy(ptmx, os.Stdin) }()
_, _ = io.Copy(os.Stdout, ptmx)
return nil
}
func main() {
if err := test(); err != nil {
log.Fatal(err)
}
}
