# Contributing
1. Sign one of the contributor license agreements below.
1. `go get golang.org/x/review/git-codereview` to install the code reviewing
tool.
1. You will need to ensure that your `GOBIN` directory (by default
`$GOPATH/bin`) is in your `PATH` so that git can find the command.
1. If you would like, you may want to set up aliases for git-codereview,
such that `git codereview change` becomes `git change`. See the
[godoc](https://godoc.org/golang.org/x/review/git-codereview) for details.
1. Should you run into issues with the git-codereview tool, please note
that all error messages will assume that you have set up these aliases.
1. Get the cloud package by running `go get -d cloud.google.com/go`.
1. If you have already checked out the source, make sure that the remote
git origin is https://code.googlesource.com/gocloud:
```
git remote set-url origin https://code.googlesource.com/gocloud
```
1. Make sure your auth is configured correctly by visiting
https://code.googlesource.com, clicking "Generate Password", and following the
directions.
1. Make changes and create a change by running `git codereview change <name>`,
provide a commit message, and use `git codereview mail` to create a Gerrit CL.
1. Keep amending to the change with `git codereview change` and mail as your
receive feedback. Each new mailed amendment will create a new patch set for
your change in Gerrit.
## Integration Tests
In addition to the unit tests, you may run the integration test suite. These
directions describe setting up your environment to run integration tests for
_all_ packages: note that many of these instructions may be redundant if you
intend only to run integration tests on a single package.
#### GCP Setup
To run the integrations tests, creation and configuration of two projects in
the Google Developers Console is required: one specifically for Firestore
integration tests, and another for all other integration tests. We'll refer to
these projects as "general project" and "Firestore project".
After creating each project, you must [create a service account](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount)
for each project. Ensure the project-level **Owner**
[IAM role](console.cloud.google.com/iam-admin/iam/project) role is added to
each service account. During the creation of the service account, you should
download the JSON credential file for use later.
Next, ensure the following APIs are enabled in the general project:
- BigQuery API
- BigQuery Data Transfer API
- Cloud Dataproc API
- Cloud Dataproc Control API Private
- Cloud Datastore API
- Cloud Firestore API
- Cloud Key Management Service (KMS) API
- Cloud Natural Language API
- Cloud OS Login API
- Cloud Pub/Sub API
- Cloud Resource Manager API
- Cloud Spanner API
- Cloud Speech API
- Cloud Translation API
- Cloud Video Intelligence API
- Cloud Vision API
- Compute Engine API
- Compute Engine Instance Group Manager API
- Container Registry API
- Firebase Rules API
- Google Cloud APIs
- Google Cloud Deployment Manager V2 API
- Google Cloud SQL
- Google Cloud Storage
- Google Cloud Storage JSON API
- Google Compute Engine Instance Group Updater API
- Google Compute Engine Instance Groups API
- Kubernetes Engine API
- Stackdriver Error Reporting API
Next, create a Datastore database in the general project, and a Firestore
database in the Firestore project.
Finally, in the general project, create an API key for the translate API:
- Go to GCP Developer Console.
- Navigate to APIs & Services > Credentials.
- Click Create Credentials > API Key.
- Save this key for use in `GCLOUD_TESTS_API_KEY` as described below.
#### Local Setup
Once the two projects are created and configured, set the following environment
variables:
- `GCLOUD_TESTS_GOLANG_PROJECT_ID`: Developers Console project's ID (e.g.
bamboo-shift-455) for the general project.
- `GCLOUD_TESTS_GOLANG_KEY`: The path to the JSON key file of the general
project's service account.
- `GCLOUD_TESTS_GOLANG_FIRESTORE_PROJECT_ID`: Developers Console project's ID
(e.g. doorway-cliff-677) for the Firestore project.
- `GCLOUD_TESTS_GOLANG_FIRESTORE_KEY`: The path to the JSON key file of the
Firestore project's service account.
- `GCLOUD_TESTS_GOLANG_KEYRING`: The full name of the keyring for the tests,
in the form
"projects/P/locations/L/keyRings/R". The creation of this is described below.
- `GCLOUD_TESTS_API_KEY`: API key for using the Translate API.
- `GCLOUD_TESTS_GOLANG_ZONE`: Compute Engine zone.
Install the [gcloud command-line tool][gcloudcli] to your machine and use it to
create some resources used in integration tests.
From the project's root directory:
``` sh
# Sets the default project in your env.
$ gcloud config set project $GCLOUD_TESTS_GOLANG_PROJECT_ID
# Authenticates the gcloud tool with your account.
$ gcloud auth login
# Create the indexes used in the datastore integration tests.
$ gcloud datastore create-indexes datastore/testdata/index.yaml
# Creates a Google Cloud storage bucket with the same name as your test project,
# and with the Stackdriver Logging service account as owner, for the sink
# integration tests in logging.
$ gsutil mb gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID
$ gsutil acl ch -g cloud-logs@google.com:O gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID
# Creates a PubSub topic for integration tests of storage notifications.
$ gcloud beta pubsub topics create go-storage-notification-test
# Next, go to the Pub/Sub dashboard in GCP console. Authorize the user
# "service-<numberic project id>@gs-project-accounts.iam.gserviceaccount.com"
# as a publisher to that topic.
# Creates a Spanner instance for the spanner integration tests.
$ gcloud beta spanner instances create go-integration-test --config regional-us-central1 --nodes 10 --description 'Instance for go client test'
# NOTE: Spanner instances are priced by the node-hour, so you may want to
# delete the instance after testing with 'gcloud beta spanner instances delete'.
$ export MY_KEYRING=some-keyring-name
$ export MY_LOCATION=global
# Creates a KMS keyring, in the same location as the default location for your
# project's buckets.
$ gcloud kms keyrings create $MY_KEYRING --location $MY_LOCATION
# Creates two keys in the keyring, named key1 and key2.
$ gcloud kms keys create key1 --keyring $MY_KEYRING --location $MY_LOCATION --purpose encryption
$ gcloud kms keys create key2 --keyring $MY_KEYRING --location $MY_LOCATION --purpose encryption
# Sets the GCLOUD_TESTS_GOLANG_KEYRING environment variable.
$ export GCLOUD_TESTS_GOLANG_KEYRING=projects/$GCLOUD_TESTS_GOLANG_PROJECT_ID/locations/$MY_LOCATION/keyRings/$MY_KEYRING
# Authorizes Google Cloud Storage to encrypt and decrypt using key1.
gsutil kms authorize -p $GCLOUD_TESTS_GOLANG_PROJECT_ID -k $GCLOUD_TESTS_GOLANG_KEYRING/cryptoKeys/key1
```
#### Running
Once you've done the necessary setup, you can run the integration tests by
running:
``` sh
$ go test -v cloud.google.com/go/...
```
#### Replay
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`
environment variable must have a non-empty value.

# Google Cloud Client Libraries for Go
[![GoDoc](https://godoc.org/cloud.google.com/go?status.svg)](https://godoc.org/cloud.google.com/go)
Go packages for [Google Cloud Platform](https://cloud.google.com) services.
``` go
import "cloud.google.com/go"
```
To install the packages on your system, *do not clone the repo*. Instead use
```
$ go get -u cloud.google.com/go/...
```
**NOTE:** Some of these packages are under development, and may occasionally
make backwards-incompatible changes.
**NOTE:** Github repo is a mirror of [https://code.googlesource.com/gocloud](https://code.googlesource.com/gocloud).

## News
_7 August 2018_
As of November 1, the code in the repo will no longer support Go versions 1.8
and earlier. No one other than AppEngine users should be on those old versions,
and AppEngine
[Standard](https://groups.google.com/forum/#!topic/google-appengine-go/e7oPNomd7ak)
and
[Flex](https://groups.google.com/forum/#!topic/google-appengine-go/wHsYtxvEbXI)
will stop supporting new deployments with those versions on that date.
Changes have been moved to [CHANGES](https://github.com/GoogleCloudPlatform/google-cloud-go/blob/master/CHANGES.md).

>
> **Beta status**: the API is largely complete, but still has outstanding
> features and bugs to be addressed. There may be minor backwards-incompatible
> changes where necessary.
>
> **Stable status**: the API is mature and ready for production use. We will
> continue addressing bugs and feature requests.

https://godoc.org/cloud.google.com/go
Visit or join the
[google-api-go-announce group](https://groups.google.com/forum/#!forum/google-api-go-announce)
for updates on these packages.
## Go Versions Supported
We support the two most recent major versions of Go. If Google App Engine uses
an older version, we support that as well.
## Authorization
By default, each API will use [Google Application Default Credentials][default-creds]
for authorization credentials used in calling the API endpoints. This will allow your
application to run in many environments without requiring explicit configuration.
[snip]:# (auth)
```go
client, err := storage.NewClient(ctx)
```
To authorize using a
[JSON key file](https://cloud.google.com/iam/docs/managing-service-account-keys),
pass
[`option.WithCredentialsFile`](https://godoc.org/google.golang.org/api/option#WithCredentialsFile)
to the `NewClient` function of the desired package. For example:
[snip]:# (auth-JSON)
```go
client, err := storage.NewClient(ctx, option.WithCredentialsFile("path/to/keyfile.json"))
```
You can exert more control over authorization by using the
[`golang.org/x/oauth2`](https://godoc.org/golang.org/x/oauth2) package to
create an `oauth2.TokenSource`. Then pass
[`option.WithTokenSource`](https://godoc.org/google.golang.org/api/option#WithTokenSource)
to the `NewClient` function:
[snip]:# (auth-ts)
```go
tokenSource := ...
client, err := storage.NewClient(ctx, option.WithTokenSource(tokenSource))
```

type Post struct {
Title string
Body string `datastore:",noindex"`
PublishedAt time.Time
}
keys := []*datastore.Key{
datastore.NameKey("Post", "post1", nil),
datastore.NameKey("Post", "post2", nil),
}
posts := []*Post{
{Title: "Post 1", Body: "...", PublishedAt: time.Now()},
{Title: "Post 2", Body: "...", PublishedAt: time.Now()},
}
if _, err := client.PutMulti(ctx, keys, posts); err != nil {
log.Fatal(err)
}

if err != nil {
log.Fatal(err)
}
```
[snip]:# (storage-2)
```go
// Read the object1 from bucket.
rc, err := client.Bucket("bucket").Object("object1").NewReader(ctx)
if err != nil {
log.Fatal(err)
}
defer rc.Close()
body, err := ioutil.ReadAll(rc)
if err != nil {
log.Fatal(err)
}
```

- [About Cloud Pubsub][cloud-pubsub]
- [API documentation][cloud-pubsub-docs]
- [Go client documentation](https://godoc.org/cloud.google.com/go/pubsub)
- [Complete sample programs](https://github.com/GoogleCloudPlatform/golang-samples/tree/master/pubsub)
### Example Usage
First create a `pubsub.Client` to use throughout your application:
[snip]:# (pubsub-1)
```go
client, err := pubsub.NewClient(ctx, "project-id")
if err != nil {
log.Fatal(err)
}
```
Then use the client to publish and subscribe:
[snip]:# (pubsub-2)
```go
// Publish "hello world" on topic1.
topic := client.Topic("topic1")
res := topic.Publish(ctx, &pubsub.Message{
Data: []byte("hello world"),
})
// The publish happens asynchronously.
// Later, you can get the result from res:
...
msgID, err := res.Get(ctx)
if err != nil {
log.Fatal(err)
}
// Use a callback to receive messages via subscription1.
sub := client.Subscription("subscription1")
err = sub.Receive(ctx, func(ctx context.Context, m *pubsub.Message) {
fmt.Println(m.Data)
m.Ack() // Acknowledge that we've consumed the message.
})
if err != nil {
log.Println(err)
}
```
## BigQuery [![GoDoc](https://godoc.org/cloud.google.com/go/bigquery?status.svg)](https://godoc.org/cloud.google.com/go/bigquery)
- [About BigQuery][cloud-bigquery]
- [API documentation][cloud-bigquery-docs]
- [Go client documentation][cloud-bigquery-ref]
- [Complete sample programs](https://github.com/GoogleCloudPlatform/golang-samples/tree/master/bigquery)
### Example Usage
First create a `bigquery.Client` to use throughout your application:
[snip]:# (bq-1)
```go
c, err := bigquery.NewClient(ctx, "my-project-ID")
if err != nil {
// TODO: Handle error.
}
```
Then use that client to interact with the API:
[snip]:# (bq-2)
```go
// Construct a query.
q := c.Query(`
SELECT year, SUM(number)
FROM [bigquery-public-data:usa_names.usa_1910_2013]
WHERE name = "William"
GROUP BY year
ORDER BY year
`)
// Execute the query.
it, err := q.Read(ctx)
if err != nil {
// TODO: Handle error.
}
// Iterate through the results.
for {
var values []bigquery.Value
err := it.Next(&values)
if err == iterator.Done {
break
}
if err != nil {
// TODO: Handle error.
}
fmt.Println(values)
}
```

[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.
}
```

spanner.Insert("Users",
[]string{"name", "email"},
[]interface{}{"alice", "a@example.com"})})
if err != nil {
log.Fatal(err)
}

spanner.Key{"alice"}, []string{"email"})
if err != nil {
log.Fatal(err)
}

# How to Create a New Release
## Prerequisites
Install [releasetool](https://github.com/googleapis/releasetool).
## Create a release
1. `cd` into the root directory, e.g., `~/go/src/cloud.google.com/go`
1. Checkout the master branch and ensure a clean and up-to-date state.
```
git checkout master
git pull --tags origin master
```
1. Run releasetool to generate a changelog from the last version. Note,
releasetool will prompt if the new version is a major, minor, or patch
version.
```
releasetool start --language go

_February 14, 2017_
Release of a client library for Spanner. See
the
[blog post](https://cloudplatform.googleblog.com/2017/02/introducing-Cloud-Spanner-a-global-database-service-for-mission-critical-applications.html).
Note that although the Spanner service is beta, the Go client library is alpha.
_December 12, 2016_
Beta release of BigQuery, DataStore, Logging and Storage. See the
[blog post](https://cloudplatform.googleblog.com/2016/12/announcing-new-google-cloud-client.html).
Also, BigQuery now supports structs. Read a row directly into a struct with
`RowIterator.Next`, and upload a row directly from a struct with `Uploader.Put`.
You can also use field tags. See the [package documentation][cloud-bigquery-ref]
for details.
_December 5, 2016_
More changes to BigQuery:
* The `ValueList` type was removed. It is no longer necessary. Instead of
```go
var v ValueList
... it.Next(&v) ..
```
use
```go
var v []Value
... it.Next(&v) ...
```
* Previously, repeatedly calling `RowIterator.Next` on the same `[]Value` or
`ValueList` would append to the slice. Now each call resets the size to zero first.
* Schema inference will infer the SQL type BYTES for a struct field of
type []byte. Previously it inferred STRING.
* The types `uint`, `uint64` and `uintptr` are no longer supported in schema
inference. BigQuery's integer type is INT64, and those types may hold values
that are not correctly represented in a 64-bit signed integer.
* The SQL types DATE, TIME and DATETIME are now supported. They correspond to
the `Date`, `Time` and `DateTime` types in the new `cloud.google.com/go/civil`
package.
_November 17, 2016_
Change to BigQuery: values from INTEGER columns will now be returned as int64,
not int. This will avoid errors arising from large values on 32-bit systems.
_November 8, 2016_
New datastore feature: datastore now encodes your nested Go structs as Entity values,
instead of a flattened list of the embedded struct's fields.
This means that you may now have twice-nested slices, eg.
```go
type State struct {
Cities []struct{
Populations []int
}
}
```
See [the announcement](https://groups.google.com/forum/#!topic/google-api-go-announce/79jtrdeuJAg) for
more details.
_November 8, 2016_
Breaking changes to datastore: contexts no longer hold namespaces; instead you
must set a key's namespace explicitly. Also, key functions have been changed
and renamed.
* The WithNamespace function has been removed. To specify a namespace in a Query, use the Query.Namespace method:
```go
q := datastore.NewQuery("Kind").Namespace("ns")
```
* All the fields of Key are exported. That means you can construct any Key with a struct literal:
```go
k := &Key{Kind: "Kind", ID: 37, Namespace: "ns"}
```
* As a result of the above, the Key methods Kind, ID, d.Name, Parent, SetParent and Namespace have been removed.
* `NewIncompleteKey` has been removed, replaced by `IncompleteKey`. Replace
```go
NewIncompleteKey(ctx, kind, parent)
```
with
```go
IncompleteKey(kind, parent)
```
and if you do use namespaces, make sure you set the namespace on the returned key.
* `NewKey` has been removed, replaced by `NameKey` and `IDKey`. Replace
```go
NewKey(ctx, kind, name, 0, parent)
NewKey(ctx, kind, "", id, parent)
```
with
```go
NameKey(kind, name, parent)
IDKey(kind, id, parent)
```
and if you do use namespaces, make sure you set the namespace on the returned key.
* The `Done` variable has been removed. Replace `datastore.Done` with `iterator.Done`, from the package `google.golang.org/api/iterator`.
* The `Client.Close` method will have a return type of error. It will return the result of closing the underlying gRPC connection.
See [the announcement](https://groups.google.com/forum/#!topic/google-api-go-announce/hqXtM_4Ix-0) for
more details.
_October 27, 2016_
Breaking change to bigquery: `NewGCSReference` is now a function,
not a method on `Client`.
New bigquery feature: `Table.LoaderFrom` now accepts a `ReaderSource`, enabling
loading data into a table from a file or any `io.Reader`.
_October 21, 2016_
Breaking change to pubsub: removed `pubsub.Done`.
Use `iterator.Done` instead, where `iterator` is the package
`google.golang.org/api/iterator`.
_October 19, 2016_
Breaking changes to cloud.google.com/go/bigquery:
* Client.Table and Client.OpenTable have been removed.
Replace
```go
client.OpenTable("project", "dataset", "table")
```
with
```go
client.DatasetInProject("project", "dataset").Table("table")
```
* Client.CreateTable has been removed.
Replace
```go
client.CreateTable(ctx, "project", "dataset", "table")
```
with
```go
client.DatasetInProject("project", "dataset").Table("table").Create(ctx)
```
* Dataset.ListTables have been replaced with Dataset.Tables.
Replace
```go
tables, err := ds.ListTables(ctx)
```
with
```go
it := ds.Tables(ctx)
for {
table, err := it.Next()
if err == iterator.Done {
break
}
if err != nil {
// TODO: Handle error.
}
// TODO: use table.
}
```
* Client.Read has been replaced with Job.Read, Table.Read and Query.Read.
Replace
```go
it, err := client.Read(ctx, job)
```
with
```go
it, err := job.Read(ctx)
```
and similarly for reading from tables or queries.
* The iterator returned from the Read methods is now named RowIterator. Its
behavior is closer to the other iterators in these libraries. It no longer
supports the Schema method; see the next item.
Replace
```go
for it.Next(ctx) {
var vals ValueList
if err := it.Get(&vals); err != nil {
// TODO: Handle error.
}
// TODO: use vals.
}
if err := it.Err(); err != nil {
// TODO: Handle error.
}
```
with
```
for {
var vals ValueList
err := it.Next(&vals)
if err == iterator.Done {
break
}
if err != nil {
// TODO: Handle error.
}
// TODO: use vals.
}
```
Instead of the `RecordsPerRequest(n)` option, write
```go
it.PageInfo().MaxSize = n
```
Instead of the `StartIndex(i)` option, write
```go
it.StartIndex = i
```
* ValueLoader.Load now takes a Schema in addition to a slice of Values.
Replace
```go
func (vl *myValueLoader) Load(v []bigquery.Value)
```
with
```go
func (vl *myValueLoader) Load(v []bigquery.Value, s bigquery.Schema)
```
* Table.Patch is replace by Table.Update.
Replace
```go
p := table.Patch()
p.Description("new description")
metadata, err := p.Apply(ctx)
```
with
```go
metadata, err := table.Update(ctx, bigquery.TableMetadataToUpdate{
Description: "new description",
})
```
* Client.Copy is replaced by separate methods for each of its four functions.
All options have been replaced by struct fields.
* To load data from Google Cloud Storage into a table, use Table.LoaderFrom.
Replace
```go
client.Copy(ctx, table, gcsRef)
```
with
```go
table.LoaderFrom(gcsRef).Run(ctx)
```
Instead of passing options to Copy, set fields on the Loader:
```go
loader := table.LoaderFrom(gcsRef)
loader.WriteDisposition = bigquery.WriteTruncate
```
* To extract data from a table into Google Cloud Storage, use
Table.ExtractorTo. Set fields on the returned Extractor instead of
passing options.
Replace
```go
client.Copy(ctx, gcsRef, table)
```
with
```go
table.ExtractorTo(gcsRef).Run(ctx)
```
* To copy data into a table from one or more other tables, use
Table.CopierFrom. Set fields on the returned Copier instead of passing options.
Replace
```go
client.Copy(ctx, dstTable, srcTable)
```
with
```go
dst.Table.CopierFrom(srcTable).Run(ctx)
```
* To start a query job, create a Query and call its Run method. Set fields
on the query instead of passing options.
Replace
```go
client.Copy(ctx, table, query)
```
with
```go
query.Run(ctx)
```
* Table.NewUploader has been renamed to Table.Uploader. Instead of options,
configure an Uploader by setting its fields.
Replace
```go
u := table.NewUploader(bigquery.UploadIgnoreUnknownValues())
```
with
```go
u := table.NewUploader(bigquery.UploadIgnoreUnknownValues())
u.IgnoreUnknownValues = true
```
_October 10, 2016_
Breaking changes to cloud.google.com/go/storage:
* AdminClient replaced by methods on Client.
Replace
```go
adminClient.CreateBucket(ctx, bucketName, attrs)
```
with
```go
client.Bucket(bucketName).Create(ctx, projectID, attrs)
```
* BucketHandle.List replaced by BucketHandle.Objects.
Replace
```go
for query != nil {
objs, err := bucket.List(d.ctx, query)
if err != nil { ... }
query = objs.Next
for _, obj := range objs.Results {
fmt.Println(obj)
}
}
```
with
```go
iter := bucket.Objects(d.ctx, query)
for {
obj, err := iter.Next()
if err == iterator.Done {
break
}
if err != nil { ... }
fmt.Println(obj)
}
```
(The `iterator` package is at `google.golang.org/api/iterator`.)
Replace `Query.Cursor` with `ObjectIterator.PageInfo().Token`.
Replace `Query.MaxResults` with `ObjectIterator.PageInfo().MaxSize`.
* ObjectHandle.CopyTo replaced by ObjectHandle.CopierFrom.
Replace
```go
attrs, err := src.CopyTo(ctx, dst, nil)
```
with
```go
attrs, err := dst.CopierFrom(src).Run(ctx)
```
Replace
```go
attrs, err := src.CopyTo(ctx, dst, &storage.ObjectAttrs{ContextType: "text/html"})
```
with
```go
c := dst.CopierFrom(src)
c.ContextType = "text/html"
attrs, err := c.Run(ctx)
```
* ObjectHandle.ComposeFrom replaced by ObjectHandle.ComposerFrom.
Replace
```go
attrs, err := dst.ComposeFrom(ctx, []*storage.ObjectHandle{src1, src2}, nil)
```
with
```go
attrs, err := dst.ComposerFrom(src1, src2).Run(ctx)
```
* ObjectHandle.Update's ObjectAttrs argument replaced by ObjectAttrsToUpdate.
Replace
```go
attrs, err := obj.Update(ctx, &storage.ObjectAttrs{ContextType: "text/html"})
```
with
```go
attrs, err := obj.Update(ctx, storage.ObjectAttrsToUpdate{ContextType: "text/html"})
```
* ObjectHandle.WithConditions replaced by ObjectHandle.If.
Replace
```go
obj.WithConditions(storage.Generation(gen), storage.IfMetaGenerationMatch(mgen))
```
with
```go
obj.Generation(gen).If(storage.Conditions{MetagenerationMatch: mgen})
```
Replace
```go
obj.WithConditions(storage.IfGenerationMatch(0))
```
with
```go
obj.If(storage.Conditions{DoesNotExist: true})
```
* `storage.Done` replaced by `iterator.Done` (from package `google.golang.org/api/iterator`).
_October 6, 2016_
Package preview/logging deleted. Use logging instead.
_September 27, 2016_
Logging client replaced with preview version (see below).
_September 8, 2016_
* New clients for some of Google's Machine Learning APIs: Vision, Speech, and
Natural Language.
* Preview version of a new [Stackdriver Logging][cloud-logging] client in
[`cloud.google.com/go/preview/logging`](https://godoc.org/cloud.google.com/go/preview/logging).
This client uses gRPC as its transport layer, and supports log reading, sinks
and metrics. It will replace the current client at `cloud.google.com/go/logging` shortly.

// Package cloud implements a more golang friendly interface to the GCE compute
// API. The code in this package is generated automatically via the generator
// implemented in "gen/main.go". The code generator creates the basic CRUD
// actions for the given resource: "Insert", "Get", "List" and "Delete".
// Additional methods by customizing the ServiceInfo object (see below).
// Generated code includes a full mock of the GCE compute API.
//
// Usage
//
// The root of the GCE compute API is the interface "Cloud". Code written using
// Cloud can be used against the actual implementation "GCE" or "MockGCE".
//
// func foo(cloud Cloud) {
// igs, err := cloud.InstanceGroups().List(ctx, "us-central1-b", filter.None)
// ...
// }
// // Run foo against the actual cloud.
// foo(NewGCE(&Service{...}))
// // Run foo with a mock.
// foo(NewMockGCE())
//
// Rate limiting and routing
//
// The generated code allows for custom policies for operation rate limiting
// and GCE project routing. See RateLimiter and ProjectRouter for more details.
//
// Mocks
//
// Mocks are automatically generated for each type implementing basic logic for
// resource manipulation. This eliminates the boilerplate required to mock GCE
// functionality. Each method will also have a corresponding "xxxHook"
// function generated in the mock structure where unit test code can hook the
// execution of the method.
//
// Mocks for different versions of the same service will share the same set of
// objects, i.e. an alpha object will be visible with beta and GA methods.
// Note that translation is done with JSON serialization between the API versions.
//
// Changing service code generation
//
// The list of services to generate is contained in "meta/meta.go". To add a
// service, add an entry to the list "meta.AllServices". An example entry:
//
// &ServiceInfo{
// Object: "InstanceGroup", // Name of the object type.
// Service: "InstanceGroups", // Name of the service.
// Resource: "instanceGroups", // Lowercase resource name (as appears in the URL).
// version: meta.VersionAlpha, // API version (one entry per version is needed).
// keyType: Zonal, // What kind of resource this is.
// serviceType: reflect.TypeOf(&alpha.InstanceGroupsService{}), // Associated golang type.
// additionalMethods: []string{ // Additional methods to generate code for.
// "SetNamedPorts",
// },
// options: <options> // Or'd ("|") together.
// }
//
// Read-only objects
//
// Services such as Regions and Zones do not allow for mutations. Specify
// "ReadOnly" in ServiceInfo.options to omit the mutation methods.
//
// Adding custom methods
//
// Some methods that may not be properly handled by the generated code. To enable
// addition of custom code to the generated mocks, set the "CustomOps" option
// in "meta.ServiceInfo" entry. This will make the generated service interface
// embed a "<ServiceName>Ops" interface. This interface MUST be written by hand
// and contain the custom method logic. Corresponding methods must be added to
// the corresponding Mockxxx and GCExxx struct types.
//
// // In "meta/meta.go":
// &ServiceInfo{
// Object: "InstanceGroup",
// ...
// options: CustomOps,
// }
//
// // In the generated code "gen.go":
// type InstanceGroups interface {
// InstanceGroupsOps // Added by CustomOps option.
// ...
// }
//
// // In hand written file:
// type InstanceGroupsOps interface {
// MyMethod()
// }
//
// func (mock *MockInstanceGroups) MyMethod() {
// // Custom mock implementation.
// }
//
// func (gce *GCEInstanceGroups) MyMethod() {
// // Custom implementation.
// }
//
// Update generated codes
//
// Run hack/update-cloudprovider-gce.sh to update the generated codes.

// From the compute API description:
//
// Sets a filter {expression} for filtering listed resources. Your {expression}
// must be in the format: field_name comparison_string literal_string.
//
// The field_name is the name of the field you want to compare. Only atomic field
// types are supported (string, number, boolean). The comparison_string must be
// either eq (equals) or ne (not equals). The literal_string is the string value
// to filter to. The literal value must be valid for the type of field you are
// filtering by (string, number, boolean). For string fields, the literal value is
// interpreted as a regular expression using RE2 syntax. The literal value must
// match the entire field.
//
// For example, to filter for instances that do not have a name of
// example-instance, you would use name ne example-instance.
//
// You can filter on nested fields. For example, you could filter on instances
// that have set the scheduling.automaticRestart field to true. Use filtering on
// nested fields to take advantage of labels to organize and search for results
// based on label values.
//
// To filter on multiple expressions, provide each separate expression within
// parentheses. For example, (scheduling.automaticRestart eq true)
// (zone eq us-central1-f). Multiple expressions are treated as AND expressions,
// meaning that resources must match all expressions to pass the filters.

---
layout: code-of-conduct
version: v1.0
---
This code of conduct outlines our expectations for participants within the **NYTimes/gziphandler** community, as well as steps to reporting unacceptable behavior. We are committed to providing a welcoming and inspiring community for all and expect our code of conduct to be honored. Anyone who violates this code of conduct may be banned from the community.
Our open source community strives to:
* **Be friendly and patient.**
* **Be welcoming**: We strive to be a community that welcomes and supports people of all backgrounds and identities. This includes, but is not limited to members of any race, ethnicity, culture, national origin, colour, immigration status, social and economic class, educational level, sex, sexual orientation, gender identity and expression, age, size, family status, political belief, religion, and mental and physical ability.
* **Be considerate**: Your work will be used by other people, and you in turn will depend on the work of others. Any decision you take will affect users and colleagues, and you should take those consequences into account when making decisions. Remember that we're a world-wide community, so you might not be communicating in someone else's primary language.
* **Be respectful**: Not all of us will agree all the time, but disagreement is no excuse for poor behavior and poor manners. We might all experience some frustration now and then, but we cannot allow that frustration to turn into a personal attack. It’s important to remember that a community where people feel uncomfortable or threatened is not a productive one.
* **Be careful in the words that we choose**: we are a community of professionals, and we conduct ourselves professionally. Be kind to others. Do not insult or put down other participants. Harassment and other exclusionary behavior aren't acceptable.
* **Try to understand why we disagree**: Disagreements, both social and technical, happen all the time. It is important that we resolve disagreements and differing views constructively. Remember that we’re different. The strength of our community comes from its diversity, people from a wide range of backgrounds. Different people have different perspectives on issues. Being unable to understand why someone holds a viewpoint doesn’t mean that they’re wrong. Don’t forget that it is human to err and blaming each other doesn’t get us anywhere. Instead, focus on helping to resolve issues and learning from mistakes.
## Definitions
Harassment includes, but is not limited to:
- Offensive comments related to gender, gender identity and expression, sexual orientation, disability, mental illness, neuro(a)typicality, physical appearance, body size, race, age, regional discrimination, political or religious affiliation
- Unwelcome comments regarding a person’s lifestyle choices and practices, including those related to food, health, parenting, drugs, and employment
- Deliberate misgendering. This includes deadnaming or persistently using a pronoun that does not correctly reflect a person's gender identity. You must address people by the name they give you when not addressing them by their username or handle
- Physical contact and simulated physical contact (eg, textual descriptions like “*hug*” or “*backrub*”) without consent or after a request to stop
- Threats of violence, both physical and psychological
- Incitement of violence towards any individual, including encouraging a person to commit suicide or to engage in self-harm
- Deliberate intimidation
- Stalking or following
- Harassing photography or recording, including logging online activity for harassment purposes
- Sustained disruption of discussion
- Unwelcome sexual attention, including gratuitous or off-topic sexual images or behaviour
- Pattern of inappropriate social contact, such as requesting/assuming inappropriate levels of intimacy with others
- Continued one-on-one communication after requests to cease
- Deliberate “outing” of any aspect of a person’s identity without their consent except as necessary to protect others from intentional abuse
- Publication of non-harassing private communication
Our open source community prioritizes marginalized people’s safety over privileged people’s comfort. We will not act on complaints regarding:
- ‘Reverse’ -isms, including ‘reverse racism,’ ‘reverse sexism,’ and ‘cisphobia’
- Reasonable communication of boundaries, such as “leave me alone,” “go away,” or “I’m not discussing this with you”
- Refusal to explain or debate social justice concepts
- Communicating in a ‘tone’ you don’t find congenial
- Criticizing racist, sexist, cissexist, or otherwise oppressive behavior or assumptions
### Diversity Statement
We encourage everyone to participate and are committed to building a community for all. Although we will fail at times, we seek to treat everyone both as fairly and equally as possible. Whenever a participant has made a mistake, we expect them to take responsibility for it. If someone has been harmed or offended, it is our responsibility to listen carefully and respectfully, and do our best to right the wrong.
Although this list cannot be exhaustive, we explicitly honor diversity in age, gender, gender identity or expression, culture, ethnicity, language, national origin, political beliefs, profession, race, religion, sexual orientation, socioeconomic status, and technical ability. We will not tolerate discrimination based on any of the protected
characteristics above, including participants with disabilities.
### Reporting Issues
If you experience or witness unacceptable behavior—or have any other concerns—please report it by contacting us via **code@nytimes.com**. All reports will be handled with discretion. In your report please include:
- Your contact information.
- Names (real, nicknames, or pseudonyms) of any individuals involved. If there are additional witnesses, please
include them as well. Your account of what occurred, and if you believe the incident is ongoing. If there is a publicly available record (e.g. a mailing list archive or a public IRC logger), please include a link.
- Any additional information that may be helpful.
After filing a report, a representative will contact you personally, review the incident, follow up with any additional questions, and make a decision as to how to respond. If the person who is harassing you is part of the response team, they will recuse themselves from handling your incident. If the complaint originates from a member of the response team, it will be handled by a different member of the response team. We will respect confidentiality requests for the purpose of protecting victims of abuse.

Gzip Handler
============
This is a tiny Go package which wraps HTTP handlers to transparently gzip the
response body, for clients which support it. Although it's usually simpler to
leave that to a reverse proxy (like nginx or Varnish), this package is useful
when that's undesirable.
## Usage
Call `GzipHandler` with any handler (an object which implements the
`http.Handler` interface), and it'll return a new handler which gzips the
response. For example:
```go
package main
import (
"io"
"net/http"
"github.com/NYTimes/gziphandler"
)
func main() {
withoutGz := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "text/plain")
io.WriteString(w, "Hello, World")
})
withGz := gziphandler.GzipHandler(withoutGz)
http.Handle("/", withGz)
http.ListenAndServe("0.0.0.0:8000", nil)
}
```
## Documentation

# Purell
Purell is a tiny Go library to normalize URLs. It returns a pure URL. Pure-ell. Sanitizer and all. Yeah, I know...
Based on the [wikipedia paper][wiki] and the [RFC 3986 document][rfc].
[![build status](https://secure.travis-ci.org/PuerkitoBio/purell.png)](http://travis-ci.org/PuerkitoBio/purell)
## Install
`go get github.com/PuerkitoBio/purell`
## Changelog
* **2016-11-14 (v1.1.0)** : IDN: Conform to RFC 5895: Fold character width (thanks to @beeker1121).
* **2016-07-27 (v1.0.0)** : Normalize IDN to ASCII (thanks to @zenovich).
* **2015-02-08** : Add fix for relative paths issue ([PR #5][pr5]) and add fix for unnecessary encoding of reserved characters ([see issue #7][iss7]).
* **v0.2.0** : Add benchmarks, Attempt IDN support.
* **v0.1.0** : Initial release.
## Examples
From `example_test.go` (note that in your code, you would import "github.com/PuerkitoBio/purell", and would prefix references to its methods and constants with "purell."):
```go
package purell
import (
"fmt"
"net/url"
)
func ExampleNormalizeURLString() {
if normalized, err := NormalizeURLString("hTTp://someWEBsite.com:80/Amazing%3f/url/",
FlagLowercaseScheme|FlagLowercaseHost|FlagUppercaseEscapes); err != nil {
panic(err)
} else {
fmt.Print(normalized)
}
// Output: http://somewebsite.com:80/Amazing%3F/url/
}
func ExampleMustNormalizeURLString() {
normalized := MustNormalizeURLString("hTTpS://someWEBsite.com:443/Amazing%fa/url/",
FlagsUnsafeGreedy)
fmt.Print(normalized)
// Output: http://somewebsite.com/Amazing%FA/url
}
func ExampleNormalizeURL() {
if u, err := url.Parse("Http://SomeUrl.com:8080/a/b/.././c///g?c=3&a=1&b=9&c=0#target"); err != nil {
panic(err)
} else {
normalized := NormalizeURL(u, FlagsUsuallySafeGreedy|FlagRemoveDuplicateSlashes|FlagRemoveFragment)
fmt.Print(normalized)
}
// Output: http://someurl.com:8080/a/c/g?c=3&a=1&b=9&c=0
}
```
## API
As seen in the examples above, purell offers three methods, `NormalizeURLString(string, NormalizationFlags) (string, error)`, `MustNormalizeURLString(string, NormalizationFlags) (string)` and `NormalizeURL(*url.URL, NormalizationFlags) (string)`. They all normalize the provided URL based on the specified flags. Here are the available flags:
```go
const (
// Safe normalizations
FlagLowercaseScheme NormalizationFlags = 1 << iota // HTTP://host -> http://host, applied by default in Go1.1
FlagLowercaseHost // http://HOST -> http://host
FlagUppercaseEscapes // http://host/t%ef -> http://host/t%EF
FlagDecodeUnnecessaryEscapes // http://host/t%41 -> http://host/tA
FlagEncodeNecessaryEscapes // http://host/!"#$ -> http://host/%21%22#$
FlagRemoveDefaultPort // http://host:80 -> http://host
FlagRemoveEmptyQuerySeparator // http://host/path? -> http://host/path
// Usually safe normalizations
FlagRemoveTrailingSlash // http://host/path/ -> http://host/path
FlagAddTrailingSlash // http://host/path -> http://host/path/ (should choose only one of these add/remove trailing slash flags)
FlagRemoveDotSegments // http://host/path/./a/b/../c -> http://host/path/a/c
// Unsafe normalizations
FlagRemoveDirectoryIndex // http://host/path/index.html -> http://host/path/
FlagRemoveFragment // http://host/path#fragment -> http://host/path
FlagForceHTTP // https://host -> http://host
FlagRemoveDuplicateSlashes // http://host/path//a///b -> http://host/path/a/b
FlagRemoveWWW // http://www.host/ -> http://host/
FlagAddWWW // http://host/ -> http://www.host/ (should choose only one of these add/remove WWW flags)
FlagSortQuery // http://host/path?c=3&b=2&a=1&b=1 -> http://host/path?a=1&b=1&b=2&c=3
// Normalizations not in the wikipedia article, required to cover tests cases
// submitted by jehiah
FlagDecodeDWORDHost // http://1113982867 -> http://66.102.7.147
FlagDecodeOctalHost // http://0102.0146.07.0223 -> http://66.102.7.147
FlagDecodeHexHost // http://0x42660793 -> http://66.102.7.147
FlagRemoveUnnecessaryHostDots // http://.host../path -> http://host/path
FlagRemoveEmptyPortSeparator // http://host:/path -> http://host/path
// Convenience set of safe normalizations
FlagsSafe NormalizationFlags = FlagLowercaseHost | FlagLowercaseScheme | FlagUppercaseEscapes | FlagDecodeUnnecessaryEscapes | FlagEncodeNecessaryEscapes | FlagRemoveDefaultPort | FlagRemoveEmptyQuerySeparator
// For convenience sets, "greedy" uses the "remove trailing slash" and "remove www. prefix" flags,
// while "non-greedy" uses the "add (or keep) the trailing slash" and "add www. prefix".
// Convenience set of usually safe normalizations (includes FlagsSafe)
FlagsUsuallySafeGreedy NormalizationFlags = FlagsSafe | FlagRemoveTrailingSlash | FlagRemoveDotSegments
FlagsUsuallySafeNonGreedy NormalizationFlags = FlagsSafe | FlagAddTrailingSlash | FlagRemoveDotSegments
// Convenience set of unsafe normalizations (includes FlagsUsuallySafe)
FlagsUnsafeGreedy NormalizationFlags = FlagsUsuallySafeGreedy | FlagRemoveDirectoryIndex | FlagRemoveFragment | FlagForceHTTP | FlagRemoveDuplicateSlashes | FlagRemoveWWW | FlagSortQuery
FlagsUnsafeNonGreedy NormalizationFlags = FlagsUsuallySafeNonGreedy | FlagRemoveDirectoryIndex | FlagRemoveFragment | FlagForceHTTP | FlagRemoveDuplicateSlashes | FlagAddWWW | FlagSortQuery
// Convenience set of all available flags
FlagsAllGreedy = FlagsUnsafeGreedy | FlagDecodeDWORDHost | FlagDecodeOctalHost | FlagDecodeHexHost | FlagRemoveUnnecessaryHostDots | FlagRemoveEmptyPortSeparator
FlagsAllNonGreedy = FlagsUnsafeNonGreedy | FlagDecodeDWORDHost | FlagDecodeOctalHost | FlagDecodeHexHost | FlagRemoveUnnecessaryHostDots | FlagRemoveEmptyPortSeparator
)
```
For convenience, the set of flags `FlagsSafe`, `FlagsUsuallySafe[Greedy|NonGreedy]`, `FlagsUnsafe[Greedy|NonGreedy]` and `FlagsAll[Greedy|NonGreedy]` are provided for the similarly grouped normalizations on [wikipedia's URL normalization page][wiki]. You can add (using the bitwise OR `|` operator) or remove (using the bitwise AND NOT `&^` operator) individual flags from the sets if required, to build your own custom set.
The [full godoc reference is available on gopkgdoc][godoc].
Some things to note:
* `FlagDecodeUnnecessaryEscapes`, `FlagEncodeNecessaryEscapes`, `FlagUppercaseEscapes` and `FlagRemoveEmptyQuerySeparator` are always implicitly set, because internally, the URL string is parsed as an URL object, which automatically decodes unnecessary escapes, uppercases and encodes necessary ones, and removes empty query separators (an unnecessary `?` at the end of the url). So this operation cannot **not** be done. For this reason, `FlagRemoveEmptyQuerySeparator` (as well as the other three) has been included in the `FlagsSafe` convenience set, instead of `FlagsUnsafe`, where Wikipedia puts it.
* The `FlagDecodeUnnecessaryEscapes` decodes the following escapes (*from -> to*):
- %24 -> $
- %26 -> &
- %2B-%3B -> +,-./0123456789:;
- %3D -> =
- %40-%5A -> @ABCDEFGHIJKLMNOPQRSTUVWXYZ
- %5F -> _
- %61-%7A -> abcdefghijklmnopqrstuvwxyz
- %7E -> ~
* When the `NormalizeURL` function is used (passing an URL object), this source URL object is modified (that is, after the call, the URL object will be modified to reflect the normalization).
* The *replace IP with domain name* normalization (`http://208.77.188.166/ → http://www.example.com/`) is obviously not possible for a library without making some network requests. This is not implemented in purell.
* The *remove unused query string parameters* and *remove default query parameters* are also not implemented, since this is a very case-specific normalization, and it is quite trivial to do with an URL object.
### Safe vs Usually Safe vs Unsafe
Purell allows you to control the level of risk you take while normalizing an URL. You can aggressively normalize, play it totally safe, or anything in between.
Consider the following URL:
`HTTPS://www.RooT.com/toto/t%45%1f///a/./b/../c/?z=3&w=2&a=4&w=1#invalid`
Normalizing with the `FlagsSafe` gives:
`https://www.root.com/toto/tE%1F///a/./b/../c/?z=3&w=2&a=4&w=1#invalid`
With the `FlagsUsuallySafeGreedy`:
`https://www.root.com/toto/tE%1F///a/c?z=3&w=2&a=4&w=1#invalid`
And with `FlagsUnsafeGreedy`:
`http://root.com/toto/tE%1F/a/c?a=4&w=1&w=2&z=3`
## TODOs
* Add a class/default instance to allow specifying custom directory index names? At the moment, removing directory index removes `(^|/)((?:default|index)\.\w{1,4})$`.

#### Support
If you do have a contribution to the package, feel free to create a Pull Request or an Issue.
#### What to contribute
If you don't know what to do, there are some features and functions that need to be done
- [ ] Refactor code
- [ ] Edit docs and [README](https://github.com/asaskevich/govalidator/README.md): spellcheck, grammar and typo check
- [ ] Create actual list of contributors and projects that currently using this package
- [ ] Resolve [issues and bugs](https://github.com/asaskevich/govalidator/issues)
- [ ] Update actual [list of functions](https://github.com/asaskevich/govalidator#list-of-functions)
- [ ] Update [list of validators](https://github.com/asaskevich/govalidator#validatestruct-2) that available for `ValidateStruct` and add new
- [ ] Implement new validators: `IsFQDN`, `IsIMEI`, `IsPostalCode`, `IsISIN`, `IsISRC` etc

A package of validators and sanitizers for strings, structs and collections. Based on [validator.js](https://github.com/chriso/validator.js).
#### Installation
Make sure that Go is installed on your computer.
Type the following command in your terminal:
go get github.com/asaskevich/govalidator
or you can get specified release of the package with `gopkg.in`:
go get gopkg.in/asaskevich/govalidator.v4
After it the package is ready to use.
#### Import package in your project
Add following line in your `*.go` file:
```go
import "github.com/asaskevich/govalidator"
```
If you are unhappy to use long `govalidator`, you can do something like this:
```go
import (
valid "github.com/asaskevich/govalidator"
)
```
#### Activate behavior to require all fields have a validation tag by default
`SetFieldsRequiredByDefault` causes validation to fail when struct fields do not include validations or are not explicitly marked as exempt (using `valid:"-"` or `valid:"email,optional"`). A good place to activate this is a package init function or the main() function.
`SetNilPtrAllowedByRequired` causes validation to pass when struct fields marked by `required` are set to nil. This is disabled by default for consistency, but some packages that need to be able to determine between `nil` and `zero value` state can use this. If disabled, both `nil` and `zero` values cause validation errors.
```go
import "github.com/asaskevich/govalidator"
func init() {
govalidator.SetFieldsRequiredByDefault(true)
}
```
Here's some code to explain it:
```go
// this struct definition will fail govalidator.ValidateStruct() (and the field values do not matter):
type exampleStruct struct {
Name string ``
Email string `valid:"email"`
}
// this, however, will only fail when Email is empty or an invalid email address:
type exampleStruct2 struct {
Name string `valid:"-"`
Email string `valid:"email"`
}
// lastly, this will only fail when Email is an invalid email address but not when it's empty:
type exampleStruct2 struct {
Name string `valid:"-"`
Email string `valid:"email,optional"`
}
```
#### Recent breaking changes (see [#123](https://github.com/asaskevich/govalidator/pull/123))
##### Custom validator function signature
A context was added as the second parameter, for structs this is the object being validated – this makes dependent validation possible.
```go
import "github.com/asaskevich/govalidator"
// old signature
func(i interface{}) bool
// new signature
func(i interface{}, o interface{}) bool
```
##### Adding a custom validator
This was changed to prevent data races when accessing custom validators.
```go
import "github.com/asaskevich/govalidator"
// before
govalidator.CustomTypeTagMap["customByteArrayValidator"] = CustomTypeValidator(func(i interface{}, o interface{}) bool {
// ...
})
// after
govalidator.CustomTypeTagMap.Set("customByteArrayValidator", CustomTypeValidator(func(i interface{}, o interface{}) bool {
// ...
}))
```

#### Examples
###### IsURL

```
###### ToString
```go
type User struct {
FirstName string
LastName string
}
str := govalidator.ToString(&User{"John", "Juan"})
println(str)
```
###### Each, Map, Filter, Count for slices
Each iterates over the slice/array and calls Iterator for every item
```go
data := []interface{}{1, 2, 3, 4, 5}
var fn govalidator.Iterator = func(value interface{}, index int) {
println(value.(int))
}
govalidator.Each(data, fn)
```
```go
data := []interface{}{1, 2, 3, 4, 5}
var fn govalidator.ResultIterator = func(value interface{}, index int) interface{} {
return value.(int) * 3
}
_ = govalidator.Map(data, fn) // result = []interface{}{1, 6, 9, 12, 15}
```
```go
data := []interface{}{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
var fn govalidator.ConditionIterator = func(value interface{}, index int) bool {
return value.(int)%2 == 0
}
_ = govalidator.Filter(data, fn) // result = []interface{}{2, 4, 6, 8, 10}
_ = govalidator.Count(data, fn) // result = 5
```
###### ValidateStruct [#2](https://github.com/asaskevich/govalidator/pull/2)
If you want to validate structs, you can use tag `valid` for any field in your structure. All validators used with this field in one tag are separated by comma. If you want to skip validation, place `-` in your tag. If you need a validator that is not on the list below, you can add it like this:
```go
govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
return str == "duck"
})
```
For completely custom validators (interface-based), see below.
Here is a list of available validators for struct fields (validator - used function):
```go
"email": IsEmail,
"url": IsURL,
"dialstring": IsDialString,
"requrl": IsRequestURL,
"requri": IsRequestURI,
"alpha": IsAlpha,
"utfletter": IsUTFLetter,
"alphanum": IsAlphanumeric,
"utfletternum": IsUTFLetterNumeric,
"numeric": IsNumeric,
"utfnumeric": IsUTFNumeric,
"utfdigit": IsUTFDigit,
"hexadecimal": IsHexadecimal,
"hexcolor": IsHexcolor,
"rgbcolor": IsRGBcolor,
"lowercase": IsLowerCase,
"uppercase": IsUpperCase,
"int": IsInt,
"float": IsFloat,
"null": IsNull,
"uuid": IsUUID,
"uuidv3": IsUUIDv3,
"uuidv4": IsUUIDv4,
"uuidv5": IsUUIDv5,
"creditcard": IsCreditCard,
"isbn10": IsISBN10,
"isbn13": IsISBN13,
"json": IsJSON,
"multibyte": IsMultibyte,
"ascii": IsASCII,
"printableascii": IsPrintableASCII,
"fullwidth": IsFullWidth,
"halfwidth": IsHalfWidth,
"variablewidth": IsVariableWidth,
"base64": IsBase64,
"datauri": IsDataURI,
"ip": IsIP,
"port": IsPort,
"ipv4": IsIPv4,
"ipv6": IsIPv6,
"dns": IsDNSName,
"host": IsHost,
"mac": IsMAC,
"latitude": IsLatitude,
"longitude": IsLongitude,
"ssn": IsSSN,
"semver": IsSemver,
"rfc3339": IsRFC3339,
"rfc3339WithoutZone": IsRFC3339WithoutZone,
"ISO3166Alpha2": IsISO3166Alpha2,
"ISO3166Alpha3": IsISO3166Alpha3,
```
Validators with parameters
```go
"range(min|max)": Range,
"length(min|max)": ByteLength,
"runelength(min|max)": RuneLength,
"matches(pattern)": StringMatches,
"in(string1|string2|...|stringN)": IsIn,
```
And here is small example of usage:
```go
type Post struct {
Title string `valid:"alphanum,required"`
Message string `valid:"duck,ascii"`
AuthorIP string `valid:"ipv4"`
Date string `valid:"-"`
}
post := &Post{
Title: "My Example Post",
Message: "duck",
AuthorIP: "123.234.54.3",
}
// Add your own struct validation tags
govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
return str == "duck"
})
result, err := govalidator.ValidateStruct(post)
if err != nil {
println("error: " + err.Error())
}
println(result)
```
###### WhiteList
```go
// Remove all characters from string ignoring characters between "a" and "z"
println(govalidator.WhiteList("a3a43a5a4a3a2a23a4a5a4a3a4", "a-z") == "aaaaaaaaaaaa")
```
###### Custom validation functions
Custom validation using your own domain specific validators is also available - here's an example of how to use it:
```go
import "github.com/asaskevich/govalidator"
type CustomByteArray [6]byte // custom types are supported and can be validated
type StructWithCustomByteArray struct {
ID CustomByteArray `valid:"customByteArrayValidator,customMinLengthValidator"` // multiple custom validators are possible as well and will be evaluated in sequence
Email string `valid:"email"`
CustomMinLength int `valid:"-"`
}
govalidator.CustomTypeTagMap.Set("customByteArrayValidator", CustomTypeValidator(func(i interface{}, context interface{}) bool {
switch v := context.(type) { // you can type switch on the context interface being validated
case StructWithCustomByteArray:
// you can check and validate against some other field in the context,
// return early or not validate against the context at all – your choice
case SomeOtherType:
// ...
default:
// expecting some other type? Throw/panic here or continue
}
switch v := i.(type) { // type switch on the struct field being validated
case CustomByteArray:
for _, e := range v { // this validator checks that the byte array is not empty, i.e. not all zeroes
if e != 0 {
return true
}
}
}
return false
}))
govalidator.CustomTypeTagMap.Set("customMinLengthValidator", CustomTypeValidator(func(i interface{}, context interface{}) bool {
switch v := context.(type) { // this validates a field against the value in another field, i.e. dependent validation
case StructWithCustomByteArray:
return len(v.ID) >= v.CustomMinLength
}
return false
}))
```
###### Custom error messages
Custom error messages are supported via annotations by adding the `~` separator - here's an example of how to use it:
```go
type Ticket struct {
Id int64 `json:"id"`
FirstName string `json:"firstname" valid:"required~First name is blank"`
}
```
#### Notes

#### Support
If you do have a contribution to the package, feel free to create a Pull Request or an Issue.
#### What to contribute
If you don't know what to do, there are some features and functions that need to be done
- [ ] Refactor code
- [ ] Edit docs and [README](https://github.com/asaskevich/govalidator/README.md): spellcheck, grammar and typo check
- [ ] Create actual list of contributors and projects that currently using this package
- [ ] Resolve [issues and bugs](https://github.com/asaskevich/govalidator/issues)
- [ ] Update actual [list of functions](https://github.com/asaskevich/govalidator#list-of-functions)
- [ ] Update [list of validators](https://github.com/asaskevich/govalidator#validatestruct-2) that available for `ValidateStruct` and add new
- [ ] Implement new validators: `IsFQDN`, `IsIMEI`, `IsPostalCode`, `IsISIN`, `IsISRC` etc
- [ ] Implement [validation by maps](https://github.com/asaskevich/govalidator/issues/224)
- [ ] Implement fuzzing testing
- [ ] Implement some struct/map/array utilities
- [ ] Implement map/array validation
- [ ] Implement benchmarking
- [ ] Implement batch of examples
- [ ] Look at forks for new features and fixes
#### Advice
Feel free to create what you want, but keep in mind when you implement new features:
- Code must be clear and readable, names of variables/constants clearly describes what they are doing
- Public functions must be documented and described in source file and added to README.md to the list of available functions
- There are must be unit-tests for any new functions and improvements

[![master](https://travis-ci.org/checkpoint-restore/go-criu.svg?branch=master)](https://travis-ci.org/checkpoint-restore/go-criu)
## go-criu -- Go bindings for [CRIU](https://criu.org/)
This repository provides Go bindings for CRIU. The code is based on the Go based PHaul
implementation from the CRIU repository. For easier inclusion into other Go projects the
CRIU Go bindings have been moved to this repository.
The Go bindings provide an easy way to use the CRIU RPC calls from Go without the need
to set up all the infrastructure to make the actual RPC connection to CRIU.
The following example would print the version of CRIU:
```
c := criu.MakeCriu()
version, err := c.GetCriuVersion()
fmt.Println(version)
```
or to just check if at least a certain CRIU version is installed:
```
c := criu.MakeCriu()
result, err := c.IsCriuAtLeast(31100)
```
## How to contribute
While bug fixes can first be identified via an "issue", that is not required.
It's ok to just open up a PR with the fix, but make sure you include the same
information you would have included in an issue - like how to reproduce it.
PRs for new features should include some background on what use cases the
new code is trying to address. When possible and when it makes sense, try to
break-up larger PRs into smaller ones - it's easier to review smaller
code changes. But only if those smaller ones make sense as stand-alone PRs.
Regardless of the type of PR, all PRs should include:
* well documented code changes
* additional testcases. Ideally, they should fail w/o your code change applied
* documentation changes
Squash your commits into logical pieces of work that might want to be reviewed
separate from the rest of the PRs. Ideally, each commit should implement a
single idea, and the PR branch should pass the tests at every commit. GitHub
makes it easy to review the cumulative effect of many commits; so, when in
doubt, use smaller commits.
PRs that fix issues should include a reference like `Closes #XXXX` in the
commit message so that github will automatically close the referenced issue
when the PR is merged.
Contributors must assert that they are in compliance with the [Developer
Certificate of Origin 1.1](http://developercertificate.org/). This is achieved
by adding a "Signed-off-by" line containing the contributor's name and e-mail
to every commit message. Your signature certifies that you wrote the patch or
otherwise have the right to pass it on as an open-source patch.
