go.mod: switch to Go modules (#20311) 

* go.mod, vendor: switch to Go modules

* travis: explicitly enable go modules in Go 1.11 and 1.12

* accounts/abi/bind: switch binding test to go modules

* travis, build: aggregate and upload go mod dependencies for PPA

* go.mod: tidy up the modules to avoid xgo writes to go.sum

* build, internal/build: drop own file/folder copier

* travis: fake build ppa only for go module dependencies

* mobile: fix CopyFile switch to package cp

* build, travis: use ephemeral debsrc GOPATH to get mod deps

/*
Package pipeline implements an HTTP request/response middleware pipeline whose
policy objects mutate an HTTP request's URL, query parameters, and/or headers before
the request is sent over the wire.
Not all policy objects mutate an HTTP request; some policy objects simply impact the
flow of requests/responses by performing operations such as logging, retry policies,
timeouts, failure injection, and deserialization of response payloads.
Implementing the Policy Interface
To implement a policy, define a struct that implements the pipeline.Policy interface's Do method. Your Do
method is called when an HTTP request wants to be sent over the network. Your Do method can perform any
operation(s) it desires. For example, it can log the outgoing request, mutate the URL, headers, and/or query
parameters, inject a failure, etc. Your Do method must then forward the HTTP request to next Policy object
in a linked-list ensuring that the remaining Policy objects perform their work. Ultimately, the last Policy
object sends the HTTP request over the network (by calling the HTTPSender's Do method).
When an HTTP response comes back, each Policy object in the linked-list gets a chance to process the response
(in reverse order). The Policy object can log the response, retry the operation if due to a transient failure
or timeout, deserialize the response body, etc. Ultimately, the last Policy object returns the HTTP response
to the code that initiated the original HTTP request.
Here is a template for how to define a pipeline.Policy object:
type myPolicy struct {
node PolicyNode
// TODO: Add configuration/setting fields here (if desired)...
}
func (p *myPolicy) Do(ctx context.Context, request pipeline.Request) (pipeline.Response, error) {
// TODO: Mutate/process the HTTP request here...
response, err := p.node.Do(ctx, request) // Forward HTTP request to next Policy & get HTTP response
// TODO: Mutate/process the HTTP response here...
return response, err // Return response/error to previous Policy
}
Implementing the Factory Interface
Each Policy struct definition requires a factory struct definition that implements the pipeline.Factory interface's New
method. The New method is called when application code wants to initiate a new HTTP request. Factory's New method is
passed a pipeline.PolicyNode object which contains a reference to the owning pipeline.Pipeline object (discussed later) and
a reference to the next Policy object in the linked list. The New method should create its corresponding Policy object
passing it the PolicyNode and any other configuration/settings fields appropriate for the specific Policy object.
Here is a template for how to define a pipeline.Policy object:
// NOTE: Once created & initialized, Factory objects should be goroutine-safe (ex: immutable);
// this allows reuse (efficient use of memory) and makes these objects usable by multiple goroutines concurrently.
type myPolicyFactory struct {
// TODO: Add any configuration/setting fields if desired...
}
func (f *myPolicyFactory) New(node pipeline.PolicyNode) Policy {
return &myPolicy{node: node} // TODO: Also initialize any configuration/setting fields here (if desired)...
}
Using your Factory and Policy objects via a Pipeline
To use the Factory and Policy objects, an application constructs a slice of Factory objects and passes
this slice to the pipeline.NewPipeline function.
func NewPipeline(factories []pipeline.Factory, sender pipeline.HTTPSender) Pipeline
This function also requires an object implementing the HTTPSender interface. For simple scenarios,
passing nil for HTTPSender causes a standard Go http.Client object to be created and used to actually
send the HTTP response over the network. For more advanced scenarios, you can pass your own HTTPSender
object in. This allows sharing of http.Client objects or the use of custom-configured http.Client objects
or other objects that can simulate the network requests for testing purposes.
Now that you have a pipeline.Pipeline object, you can create a pipeline.Request object (which is a simple
wrapper around Go's standard http.Request object) and pass it to Pipeline's Do method along with passing a
context.Context for cancelling the HTTP request (if desired).
type Pipeline interface {
Do(ctx context.Context, methodFactory pipeline.Factory, request pipeline.Request) (pipeline.Response, error)
}
Do iterates over the slice of Factory objects and tells each one to create its corresponding
Policy object. After the linked-list of Policy objects have been created, Do calls the first
Policy object passing it the Context & HTTP request parameters. These parameters now flow through
all the Policy objects giving each object a chance to look at and/or mutate the HTTP request.
The last Policy object sends the message over the network.
When the network operation completes, the HTTP response and error return values pass
back through the same Policy objects in reverse order. Most Policy objects ignore the
response/error but some log the result, retry the operation (depending on the exact
reason the operation failed), or deserialize the response's body. Your own Policy
objects can do whatever they like when processing outgoing requests or incoming responses.
Note that after an I/O request runs to completion, the Policy objects for that request
are garbage collected. However, Pipeline object (like Factory objects) are goroutine-safe allowing
them to be created once and reused over many I/O operations. This allows for efficient use of
memory and also makes them safely usable by multiple goroutines concurrently.
Inserting a Method-Specific Factory into the Linked-List of Policy Objects
While Pipeline and Factory objects can be reused over many different operations, it is
common to have special behavior for a specific operation/method. For example, a method
may need to deserialize the response's body to an instance of a specific data type.
To accommodate this, the Pipeline's Do method takes an additional method-specific
Factory object. The Do method tells this Factory to create a Policy object and
injects this method-specific Policy object into the linked-list of Policy objects.
When creating a Pipeline object, the slice of Factory objects passed must have 1
(and only 1) entry marking where the method-specific Factory should be injected.
The Factory marker is obtained by calling the pipeline.MethodFactoryMarker() function:
func MethodFactoryMarker() pipeline.Factory
Creating an HTTP Request Object
The HTTP request object passed to Pipeline's Do method is not Go's http.Request struct.
Instead, it is a pipeline.Request struct which is a simple wrapper around Go's standard
http.Request. You create a pipeline.Request object by calling the pipeline.NewRequest function:
func NewRequest(method string, url url.URL, options pipeline.RequestOptions) (request pipeline.Request, err error)
To this function, you must pass a pipeline.RequestOptions that looks like this:
type RequestOptions struct {
// The readable and seekable stream to be sent to the server as the request's body.
Body io.ReadSeeker
// The callback method (if not nil) to be invoked to report progress as the stream is uploaded in the HTTP request.
Progress ProgressReceiver
}
The method and struct ensure that the request's body stream is a read/seekable stream.
A seekable stream is required so that upon retry, the final Policy object can seek
the stream back to the beginning before retrying the network request and re-uploading the
body. In addition, you can associate a ProgressReceiver callback function which will be
invoked periodically to report progress while bytes are being read from the body stream
and sent over the network.
Processing the HTTP Response
When an HTTP response comes in from the network, a reference to Go's http.Response struct is
embedded in a struct that implements the pipeline.Response interface:
type Response interface {
Response() *http.Response
}
This interface is returned through all the Policy objects. Each Policy object can call the Response
interface's Response method to examine (or mutate) the embedded http.Response object.
A Policy object can internally define another struct (implementing the pipeline.Response interface)
that embeds an http.Response and adds additional fields and return this structure to other Policy
objects. This allows a Policy object to deserialize the body to some other struct and return the
original http.Response and the additional struct back through the Policy chain. Other Policy objects
can see the Response but cannot see the additional struct with the deserialized body. After all the
Policy objects have returned, the pipeline.Response interface is returned by Pipeline's Do method.
The caller of this method can perform a type assertion attempting to get back to the struct type
really returned by the Policy object. If the type assertion is successful, the caller now has
access to both the http.Response and the deserialized struct object.*/

##### Fixed Issues
- https://github.com/Azure/azure-sdk-for-go/issues/196
- https://github.com/Azure/azure-sdk-for-go/issues/213
------
## v0.1.0-beta
This release addresses the issues raised against the alpha release and adds more features. Most
notably, to address the challenges of encoding JSON
(see the [comments](https://github.com/Azure/go-autorest#handling-empty-values) in the
[go-autorest](https://github.com/Azure/go-autorest) package) by using pointers for *all* structure
fields (with the exception of enumerations). The
[go-autorest/autorest/to](https://github.com/Azure/go-autorest/tree/master/autorest/to) package
provides helpers to convert to / from pointers. The examples demonstrate their usage.
Additionally, the packages now align with Go coding standards and pass both `golint` and `govet`.
Accomplishing this required renaming various fields and parameters (such as changing Url to URL).
##### Changes
- Changed request / response structures to use pointer fields.
- Changed methods to return `error` instead of `autorest.Error`.
- Re-divided methods to ease asynchronous requests.
- Added paged results support.
- Added a UserAgent string.
- Added changes necessary to pass golint and govet.
- Updated README.md with details on asynchronous requests and paging.
- Saved package dependencies through Godep (for the entire SDK).
##### Fixed Issues:
- https://github.com/Azure/azure-sdk-for-go/issues/205
- https://github.com/Azure/azure-sdk-for-go/issues/206
- https://github.com/Azure/azure-sdk-for-go/issues/211
- https://github.com/Azure/azure-sdk-for-go/issues/212
-----
## v0.1.0-alpha
This release introduces the Azure Resource Manager packages generated from the corresponding
[Swagger API](http://swagger.io) [definitions](https://github.com/Azure/azure-rest-api-specs).

/*
Package azblob allows you to manipulate Azure Storage containers and blobs objects.
URL Types
The most common types you'll work with are the XxxURL types. The methods of these types make requests
against the Azure Storage Service.
- ServiceURL's methods perform operations on a storage account.
- ContainerURL's methods perform operations on an account's container.
- BlockBlobURL's methods perform operations on a container's block blob.
- AppendBlobURL's methods perform operations on a container's append blob.
- PageBlobURL's methods perform operations on a container's page blob.
- BlobURL's methods perform operations on a container's blob regardless of the blob's type.
Internally, each XxxURL object contains a URL and a request pipeline. The URL indicates the endpoint where each HTTP
request is sent and the pipeline indicates how the outgoing HTTP request and incoming HTTP response is processed.
The pipeline specifies things like retry policies, logging, deserialization of HTTP response payloads, and more.
Pipelines are threadsafe and may be shared by multiple XxxURL objects. When you create a ServiceURL, you pass
an initial pipeline. When you call ServiceURL's NewContainerURL method, the new ContainerURL object has its own
URL but it shares the same pipeline as the parent ServiceURL object.
To work with a blob, call one of ContainerURL's 4 NewXxxBlobURL methods depending on how you want to treat the blob.
To treat the blob as a block blob, append blob, or page blob, call NewBlockBlobURL, NewAppendBlobURL, or NewPageBlobURL
respectively. These three types are all identical except for the methods they expose; each type exposes the methods
relevant to the type of blob represented. If you're not sure how you want to treat a blob, you can call NewBlobURL;
this returns an object whose methods are relevant to any kind of blob. When you call ContainerURL's NewXxxBlobURL,
the new XxxBlobURL object has its own URL but it shares the same pipeline as the parent ContainerURL object. You
can easily switch between blob types (method sets) by calling a ToXxxBlobURL method.
If you'd like to use a different pipeline with a ServiceURL, ContainerURL, or XxxBlobURL object, then call the XxxURL
object's WithPipeline method passing in the desired pipeline. The WithPipeline methods create a new XxxURL object
with the same URL as the original but with the specified pipeline.
Note that XxxURL objects use little memory, are goroutine-safe, and many objects share the same pipeline. This means that
XxxURL objects share a lot of system resources making them very efficient.
All of XxxURL's methods that make HTTP requests return rich error handling information so you can discern network failures,
transient failures, timeout failures, service failures, etc. See the StorageError interface for more information and an
example of how to do deal with errors.
URL and Shared Access Signature Manipulation
The library includes a BlobURLParts type for deconstructing and reconstructing URLs. And you can use the following types
for generating and parsing Shared Access Signature (SAS)
- Use the AccountSASSignatureValues type to create a SAS for a storage account.
- Use the BlobSASSignatureValues type to create a SAS for a container or blob.
- Use the SASQueryParameters type to turn signature values in to query parameres or to parse query parameters.
To generate a SAS, you must use the SharedKeyCredential type.
Credentials
When creating a request pipeline, you must specify one of this package's credential types.
- Call the NewAnonymousCredential function for requests that contain a Shared Access Signature (SAS).
- Call the NewSharedKeyCredential function (with an account name & key) to access any account resources. You must also use this
to generate Shared Access Signatures.
HTTP Request Policy Factories
This package defines several request policy factories for use with the pipeline package.
Most applications will not use these factories directly; instead, the NewPipeline
function creates these factories, initializes them (via the PipelineOptions type)
and returns a pipeline object for use by the XxxURL objects.
However, for advanced scenarios, developers can access these policy factories directly
and even create their own and then construct their own pipeline in order to affect HTTP
requests and responses performed by the XxxURL objects. For example, developers can
introduce their own logging, random failures, request recording & playback for fast
testing, HTTP request pacing, alternate retry mechanisms, metering, metrics, etc. The
possibilities are endless!
Below are the request pipeline policy factory functions that are provided with this
package:
- NewRetryPolicyFactory Enables rich retry semantics for failed HTTP requests.
- NewRequestLogPolicyFactory Enables rich logging support for HTTP requests/responses & failures.
- NewTelemetryPolicyFactory Enables simple modification of the HTTP request's User-Agent header so each request reports the SDK version & language/runtime making the requests.
- NewUniqueRequestIDPolicyFactory Adds a x-ms-client-request-id header with a unique UUID value to an HTTP request to help with diagnosing failures.
Also, note that all the NewXxxCredential functions return request policy factory objects which get injected into the pipeline.

# BigCache [![Build Status](https://travis-ci.org/allegro/bigcache.svg?branch=master)](https://travis-ci.org/allegro/bigcache)&nbsp;[![Coverage Status](https://coveralls.io/repos/github/allegro/bigcache/badge.svg?branch=master)](https://coveralls.io/github/allegro/bigcache?branch=master)&nbsp;[![GoDoc](https://godoc.org/github.com/allegro/bigcache?status.svg)](https://godoc.org/github.com/allegro/bigcache)&nbsp;[![Go Report Card](https://goreportcard.com/badge/github.com/allegro/bigcache)](https://goreportcard.com/report/github.com/allegro/bigcache)
Fast, concurrent, evicting in-memory cache written to keep big number of entries without impact on performance.
BigCache keeps entries on heap but omits GC for them. To achieve that operations on bytes arrays take place,
therefore entries (de)serialization in front of the cache will be needed in most use cases.
## Usage
### Simple initialization
```go
import "github.com/allegro/bigcache"
cache, _ := bigcache.NewBigCache(bigcache.DefaultConfig(10 * time.Minute))
cache.Set("my-unique-key", []byte("value"))
entry, _ := cache.Get("my-unique-key")
fmt.Println(string(entry))
```
### Custom initialization
When cache load can be predicted in advance then it is better to use custom initialization because additional memory
allocation can be avoided in that way.
```go
import (
"log"
"github.com/allegro/bigcache"
)
config := bigcache.Config {
// number of shards (must be a power of 2)
Shards: 1024,
// time after which entry can be evicted
LifeWindow: 10 * time.Minute,
// rps * lifeWindow, used only in initial memory allocation
MaxEntriesInWindow: 1000 * 10 * 60,
// max entry size in bytes, used only in initial memory allocation
MaxEntrySize: 500,
// prints information about additional memory allocation
Verbose: true,
// cache will not allocate more memory than this limit, value in MB
// if value is reached then the oldest entries can be overridden for the new ones
// 0 value means no size limit
HardMaxCacheSize: 8192,
// callback fired when the oldest entry is removed because of its expiration time or no space left
// for the new entry, or because delete was called. A bitmask representing the reason will be returned.
// Default value is nil which means no callback and it prevents from unwrapping the oldest entry.
OnRemove: nil,
// OnRemoveWithReason is a callback fired when the oldest entry is removed because of its expiration time or no space left
// for the new entry, or because delete was called. A constant representing the reason will be passed through.
// Default value is nil which means no callback and it prevents from unwrapping the oldest entry.
// Ignored if OnRemove is specified.
OnRemoveWithReason: nil,
}
cache, initErr := bigcache.NewBigCache(config)
if initErr != nil {
log.Fatal(initErr)
}
cache.Set("my-unique-key", []byte("value"))
if entry, err := cache.Get("my-unique-key"); err == nil {
fmt.Println(string(entry))
}
```
## Benchmarks
Three caches were compared: bigcache, [freecache](https://github.com/coocood/freecache) and map.
Benchmark tests were made using an i7-6700K with 32GB of RAM on Windows 10.
### Writes and reads
```bash
cd caches_bench; go test -bench=. -benchtime=10s ./... -timeout 30m
BenchmarkMapSet-8 3000000 569 ns/op 202 B/op 3 allocs/op
BenchmarkConcurrentMapSet-8 1000000 1592 ns/op 347 B/op 8 allocs/op
BenchmarkFreeCacheSet-8 3000000 775 ns/op 355 B/op 2 allocs/op
BenchmarkBigCacheSet-8 3000000 640 ns/op 303 B/op 2 allocs/op
BenchmarkMapGet-8 5000000 407 ns/op 24 B/op 1 allocs/op
BenchmarkConcurrentMapGet-8 3000000 558 ns/op 24 B/op 2 allocs/op
BenchmarkFreeCacheGet-8 2000000 682 ns/op 136 B/op 2 allocs/op
BenchmarkBigCacheGet-8 3000000 512 ns/op 152 B/op 4 allocs/op
BenchmarkBigCacheSetParallel-8 10000000 225 ns/op 313 B/op 3 allocs/op
BenchmarkFreeCacheSetParallel-8 10000000 218 ns/op 341 B/op 3 allocs/op
BenchmarkConcurrentMapSetParallel-8 5000000 318 ns/op 200 B/op 6 allocs/op
BenchmarkBigCacheGetParallel-8 20000000 178 ns/op 152 B/op 4 allocs/op
BenchmarkFreeCacheGetParallel-8 20000000 295 ns/op 136 B/op 3 allocs/op
BenchmarkConcurrentMapGetParallel-8 10000000 237 ns/op 24 B/op 2 allocs/op
```
Writes and reads in bigcache are faster than in freecache.
Writes to map are the slowest.
### GC pause time
```bash
cd caches_bench; go run caches_gc_overhead_comparison.go
Number of entries: 20000000
GC pause for bigcache: 5.8658ms
GC pause for freecache: 32.4341ms
GC pause for map: 52.9661ms
```
Test shows how long are the GC pauses for caches filled with 20mln of entries.
Bigcache and freecache have very similar GC pause time.
It is clear that both reduce GC overhead in contrast to map
which GC pause time took more than 10 seconds.
## How it works
BigCache relies on optimization presented in 1.5 version of Go ([issue-9477](https://github.com/golang/go/issues/9477)).
This optimization states that if map without pointers in keys and values is used then GC will omit its content.
Therefore BigCache uses `map[uint64]uint32` where keys are hashed and values are offsets of entries.
Entries are kept in bytes array, to omit GC again.
Bytes array size can grow to gigabytes without impact on performance
because GC will only see single pointer to it.
## Bigcache vs Freecache
Both caches provide the same core features but they reduce GC overhead in different ways.
Bigcache relies on `map[uint64]uint32`, freecache implements its own mapping built on
slices to reduce number of pointers.
Results from benchmark tests are presented above.
One of the advantage of bigcache over freecache is that you don’t need to know
the size of the cache in advance, because when bigcache is full,
it can allocate additional memory for new entries instead of
overwriting existing ones as freecache does currently.
However hard max size in bigcache also can be set, check [HardMaxCacheSize](https://godoc.org/github.com/allegro/bigcache#Config).
## HTTP Server
This package also includes an easily deployable HTTP implementation of BigCache, which can be found in the [server](/server) package.

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the

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.

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

## areflect
Helper functions to work with the `reflect` package. Contains
`ForceExport()`, which bypasses the check in `reflect.Value` that
prevents accessing unexported attributes.
## monotime
Provides access to a fast monotonic clock source, to fill in the gap in the
[Go standard library, which lacks one](https://github.com/golang/go/issues/12914).
Don't use `time.Now()` in code that needs to time things or otherwise assume
that time passes at a constant rate, instead use `monotime.Now()`.
## cmd
See the [cmd](cmd) directory.
## dscp
Provides `ListenTCPWithTOS()`, which is a replacement for `net.ListenTCP()`
that allows specifying the ToS (Type of Service), to specify DSCP / ECN /
class of service flags to use for incoming connections.
## key
Provides a common type used across various Arista projects, named `key.Key`,
which is used to work around the fact that Go can't let one
use a non-hashable type as a key to a `map`, and we sometimes need to use
a `map[string]interface{}` (or something containing one) as a key to maps.
As a result, we frequently use `map[key.Key]interface{}` instead of just
`map[interface{}]interface{}` when we need a generic key-value collection.
## lanz
A client for [LANZ](https://eos.arista.com/latency-analyzer-lanz-architectures-and-configuration/)
streaming servers. It connects to a LANZ streaming server,
listens for notifications, decodes them and sends the LANZ protobuf on the
provided channel.
## monitor
A library to help expose monitoring metrics on top of the
[`expvar`](https://golang.org/pkg/expvar/) infrastructure.
## netns
`netns.Do(namespace, cb)` provides a handy mechanism to execute the given
callback `cb` in the given [network namespace](https://lwn.net/Articles/580893/).
## pathmap
A datastructure for mapping keys of type string slice to values. It
allows for some fuzzy matching.
## test
This is a [Go](http://golang.org/) library to help in writing unit tests.
## Examples
TBD
