# [v1.45.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.45.0)
* FEATURE: allow setting `-retentionPeriod` smaller than one month. I.e. `-retentionPeriod=3d`, `-retentionPeriod=2w`, etc. is supported now.
See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/173
* FEATURE: optimize more cases according to https://utcc.utoronto.ca/~cks/space/blog/sysadmin/PrometheusLabelNonOptimization . Now the following cases are optimized too:

* FEATURE: vmagent: add `stream parse` mode. This mode allows reducing memory usage when individual scrape targets expose tens of millions of metrics.
For example, during scraping Prometheus in [federation](https://prometheus.io/docs/prometheus/latest/federation/) mode.
See `-promscrape.streamParse` command-line option and `stream_parse: true` config option for `scrape_config` section in `-promscrape.config`.
See also [troubleshooting docs for vmagent](https://victoriametrics.github.io/vmagent.html#troubleshooting).
See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/825 and [troubleshooting docs for vmagent](https://victoriametrics.github.io/vmagent.html#troubleshooting).
* FEATURE: vmalert: add `-dryRun` command-line option for validating the provided config files without the need to start `vmalert` service.
* FEATURE: accept optional third argument of string type at `topk_*` and `bottomk_*` functions. This is label name for additional time series to return with the sum of time series outside top/bottom K. See [MetricsQL docs](https://victoriametrics.github.io/MetricsQL.html) for more details.
* FEATURE: vmagent: expose `/api/v1/targets` page according to [the corresponding Prometheus API](https://prometheus.io/docs/prometheus/latest/querying/api/#targets).

# 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,
available at [http://contributor-covenant.org/version/1/2/0/](http://contributor-covenant.org/version/1/2/0/)

# Contributing
1. [File an issue](https://github.com/googleapis/google-cloud-go/issues/new/choose).
The issue will be used to discuss the bug or feature and should be created
before sending a CL.
1. [Install Go](https://golang.org/dl/).
1. Ensure that your `GOBIN` directory (by default `$(go env GOPATH)/bin`)
is in your `PATH`.
1. Check it's working by running `go version`.
* If it doesn't work, check the install location, usually
`/usr/local/go`, is on your `PATH`.
1. Sign one of the
[contributor license agreements](#contributor-license-agreements) below.
1. Clone the repo:
`git clone https://github.com/googleapis/google-cloud-go`
1. Change into the checked out source:
`cd google-cloud-go`
1. Fork the repo.
1. Set your fork as a remote:
`git remote add fork git@github.com:GITHUB_USERNAME/google-cloud-go.git`
1. Make changes, commit to your fork.
Commit messages should follow the
[Conventional Commits Style](https://www.conventionalcommits.org). The scope
portion should always be filled with the name of the package affected by the
changes being made. For example:
```
feat(functions): add gophers codelab
```
1. Send a pull request with your changes.
To minimize friction, consider setting `Allow edits from maintainers` on the
PR, which will enable project committers and automation to update your PR.
1. A maintainer will review the pull request and make comments.
Prefer adding additional commits over amending and force-pushing since it can
be difficult to follow code reviews when the commit history changes.
Commits will be squashed when they're merged.
## Testing
We test code against two versions of Go, the minimum and maximum versions
supported by our clients. To see which versions these are checkout our
[README](README.md#supported-versions).
### 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
- Cloud 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 indexes create datastore/testdata/index.yaml
# Creates a Google Cloud storage bucket with the same name as your test project,
# and with the Cloud 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://pkg.go.dev/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:
1. Change to your project directory:
```
cd /my/cloud/project
```
1. Get the package you want to use. Some products have their own module, so it's
best to `go get` the package(s) you want to use:
```
$ go get cloud.google.com/go/firestore # Replace with the package you want to use.
```
**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).

Documentation and examples are available at [pkg.go.dev/cloud.google.com/go](https://pkg.go.dev/cloud.google.com/go)
## [Go Versions Supported](#supported-versions)
We currently support Go versions 1.11 and newer.
## Authorization
By default, each API will use [Google Application Default Credentials](https://developers.google.com/identity/protocols/application-default-credentials)
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://pkg.go.dev/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://pkg.go.dev/golang.org/x/oauth2) package to
create an `oauth2.TokenSource`. Then pass
[`option.WithTokenSource`](https://pkg.go.dev/google.golang.org/api/option#WithTokenSource)
to the `NewClient` function:
[snip]:# (auth-ts)
```go
tokenSource := ...
client, err := storage.NewClient(ctx, option.WithTokenSource(tokenSource))
```

# Setup from scratch
1. [Install Go](https://golang.org/dl/).
1. Ensure that your `GOBIN` directory (by default `$(go env GOPATH)/bin`)
is in your `PATH`.
1. Check it's working by running `go version`.
* If it doesn't work, check the install location, usually
`/usr/local/go`, is on your `PATH`.
1. Sign one of the
[contributor license agreements](#contributor-license-agreements) below.
1. Clone the repo:
`git clone https://github.com/googleapis/google-cloud-go`
1. Change into the checked out source:
`cd google-cloud-go`
1. Fork the repo and add your fork as a secondary remote (this is necessary in
order to create PRs).
# Which module to release?
The Go client libraries have several modules. Each module does not strictly
correspond to a single library - they correspond to trees of directories. If a
file needs to be released, you must release the closest ancestor module.
To see all modules:
```
$ cat `find . -name go.mod` | grep module
module cloud.google.com/go
module cloud.google.com/go/bigtable
module cloud.google.com/go/firestore
module cloud.google.com/go/bigquery
module cloud.google.com/go/storage
module cloud.google.com/go/datastore
module cloud.google.com/go/pubsub
module cloud.google.com/go/spanner
module cloud.google.com/go/logging
```
The `cloud.google.com/go` is the repository root module. Each other module is
a submodule.
So, if you need to release a change in `bigtable/bttest/inmem.go`, the closest
ancestor module is `cloud.google.com/go/bigtable` - so you should release a new
version of the `cloud.google.com/go/bigtable` submodule.
If you need to release a change in `asset/apiv1/asset_client.go`, the closest
ancestor module is `cloud.google.com/go` - so you should release a new version
of the `cloud.google.com/go` repository root module. Note: releasing
`cloud.google.com/go` has no impact on any of the submodules, and vice-versa.
They are released entirely independently.
# Test failures
If there are any test failures in the Kokoro build, releases are blocked until
the failures have been resolved.
# How to release `cloud.google.com/go`
1. Check for failures in the
[continuous Kokoro build](http://go/google-cloud-go-continuous). If there are any
failures in the most recent build, address them before proceeding with the
release.
1. Navigate to `~/code/gocloud/` and switch to master.
1. `git pull`
1. Run `git tag -l | grep -v beta | grep -v alpha` to see all existing releases.
The current latest tag `$CV` is the largest tag. It should look something
like `vX.Y.Z` (note: ignore all `LIB/vX.Y.Z` tags - these are tags for a
specific library, not the module root). We'll call the current version `$CV`
and the new version `$NV`.
1. On master, run `git log $CV...` to list all the changes since the last
release. NOTE: You must manually visually parse out changes to submodules [1]
(the `git log` is going to show you things in submodules, which are not going
to be part of your release).
1. Edit `CHANGES.md` to include a summary of the changes.
1. `cd internal/version && go generate && cd -`
1. Commit the changes, push to your fork, and create a PR.
1. Wait for the PR to be reviewed and merged. Once it's merged, and without
merging any other PRs in the meantime:
a. Switch to master.
b. `git pull`
c. Tag the repo with the next version: `git tag $NV`.
d. Push the tag to origin:
`git push origin $NV`
1. Update [the releases page](https://github.com/googleapis/google-cloud-go/releases)
with the new release, copying the contents of `CHANGES.md`.
1. Run `go get cloud.google.com/go@vX.Y.Z` then wait for the release
to show up on http://pkg.go.dev/cloud.google.com/go (a few minutes).
1. Go to the [doc publishing job](http://go/google-cloud-go-publish-docs) and
trigger the job with the following environment variables:
`MODULE=cloud.google.com,VERSION=vX.Y.Z`.
Replace the version with the value for the module you're
releasing. See [`publish_docs.sh`](/internal/kokoro/publish_docs.sh).
# How to release a submodule
We have several submodules, including `cloud.google.com/go/logging`,
`cloud.google.com/go/datastore`, and so on.
To release a submodule:
(these instructions assume we're releasing `cloud.google.com/go/datastore` - adjust accordingly)
1. Check for failures in the
[continuous Kokoro build](http://go/google-cloud-go-continuous). If there are any
failures in the most recent build, address them before proceeding with the
release. (This applies even if the failures are in a different submodule from the one
being released.)
1. Navigate to `~/code/gocloud/` and switch to master.
1. `git pull`
1. Run `git tag -l | grep datastore | grep -v beta | grep -v alpha` to see all
existing releases. The current latest tag `$CV` is the largest tag. It
should look something like `datastore/vX.Y.Z`. We'll call the current version
`$CV` and the new version `$NV`.
1. On master, run `git log $CV.. -- datastore/` to list all the changes to the
submodule directory since the last release.
1. Edit `datastore/CHANGES.md` to include a summary of the changes.
1. `cd internal/version && go generate && cd -`
1. Commit the changes, push to your fork, and create a PR.
1. Wait for the PR to be reviewed and merged. Once it's merged, and without
merging any other PRs in the meantime:
a. Switch to master.
b. `git pull`
c. Tag the repo with the next version: `git tag $NV`.
d. Push the tag to origin:
`git push origin $NV`
1. Update [the releases page](https://github.com/googleapis/google-cloud-go/releases)
with the new release, copying the contents of `datastore/CHANGES.md`.
1. Run `go get cloud.google.com/go/datastore@vX.Y.Z` then wait for the release
to show up on http://pkg.go.dev/cloud.google.com/go/datastore (a few
minutes).
1. Go to the [doc publishing job](http://go/google-cloud-go-publish-docs) and
trigger the job with the following environment variables:
`MODULE=cloud.google.com/go/datastore,VERSION=vX.Y.Z`.
Replace the module path and version with the values for the module you're
releasing. You can leave all of the other fields blank.
See [`publish_docs.sh`](/internal/kokoro/publish_docs.sh).
# Appendix
1: This should get better as submodule tooling matures.

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

is generated by `internal/gapicgen/generator`. It's processed by external tools
to build lists of all of the packages.
Don't make breaking changes to the format without consulting with the external
tools.
One day, we may want to create individual `.repo-metadata.json` files next to
each package, which is the pattern followed by some other languages. External
tools would then talk to pkg.go.dev or some other service to get the overall
list of packages and use the `.repo-metadata.json` files to get the additional
metadata required. For now, `.repo-metadata-full.json` includes everything.

# Changes
## v1.12.0
- V4 signed URL fixes:
- Fix encoding of spaces in query parameters.
- Add fields that were missing from PostPolicyV4 policy conditions.
- Fix Query to correctly list prefixes as well as objects when SetAttrSelection
is used.
## v1.11.0
- Add support for CustomTime and NoncurrentTime object lifecycle management
features.
## v1.10.0
- Bump dependency on google.golang.org/api to capture changes to retry logic
which will make retries on writes more resilient.
- Improve documentation for Writer.ChunkSize.
- Fix a bug in lifecycle to allow callers to clear lifecycle rules on a bucket.
## v1.9.0
- Add retry for transient network errors on most operations (with the exception
of writes).
- Bump dependency for google.golang.org/api to capture a change in the default
HTTP transport which will improve performance for reads under heavy load.
- Add CRC32C checksum validation option to Composer.
## v1.8.0
- Add support for V4 signed post policies.
## v1.7.0
- V4 signed URL support:
- Add support for bucket-bound domains and virtual hosted style URLs.
- Add support for query parameters in the signature.
- Fix text encoding to align with standards.
- Add the object name to query parameters for write calls.
- Fix retry behavior when reading files with Content-Encoding gzip.
- Fix response header in reader.
- New code examples:
- Error handling for `ObjectHandle` preconditions.
- Existence checks for buckets and objects.
## v1.6.0
- Updated option handling:
- Don't drop custom scopes (#1756)
- Don't drop port in provided endpoint (#1737)
## v1.5.0
- Honor WithEndpoint client option for reads as well as writes.
- Add archive storage class to docs.
- Make fixes to storage benchwrapper.
## v1.4.0
- When listing objects in a bucket, allow callers to specify which attributes
are queried. This allows for performance optimization.
## v1.3.0
- Use `storage.googleapis.com/storage/v1` by default for GCS requests
instead of `www.googleapis.com/storage/v1`.
## v1.2.1
- Fixed a bug where UniformBucketLevelAccess and BucketPolicyOnly were not
being sent in all cases.
## v1.2.0
- Add support for UniformBucketLevelAccess. This configures access checks
to use only bucket-level IAM policies.
See: https://godoc.org/cloud.google.com/go/storage#UniformBucketLevelAccess.
- Fix userAgent to use correct version.
## v1.1.2
- Fix memory leak in BucketIterator and ObjectIterator.
## v1.1.1
- Send BucketPolicyOnly even when it's disabled.
## v1.1.0
- Performance improvements for ObjectIterator and BucketIterator.
- Fix Bucket.ObjectIterator size calculation checks.
- Added HMACKeyOptions to all the methods which allows for options such as
UserProject to be set per invocation and optionally be used.
## v1.0.0
This is the first tag to carve out storage as its own module. See:
https://github.com/golang/go/wiki/Modules#is-it-possible-to-add-a-module-to-a-multi-module-repository.

```go
client, err := storage.NewClient(ctx)
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)

Package storage provides an easy way to work with Google Cloud Storage.
Google Cloud Storage stores data in named objects, which are grouped into buckets.
More information about Google Cloud Storage is available at
https://cloud.google.com/storage/docs.
See https://godoc.org/cloud.google.com/go for authentication, timeouts,
connection pooling and similar aspects of this package.
All of the methods of this package use exponential backoff to retry calls that fail
with certain errors, as described in
https://cloud.google.com/storage/docs/exponential-backoff. Retrying continues
indefinitely unless the controlling context is canceled or the client is closed. See
context.WithTimeout and context.WithCancel.
Creating a Client
To start working with this package, create a client:
ctx := context.Background()
client, err := storage.NewClient(ctx)
if err != nil {
// TODO: Handle error.
}
The client will use your default application credentials. Clients should be
reused instead of created as needed. The methods of Client are safe for
concurrent use by multiple goroutines.
If you only wish to access public data, you can create
an unauthenticated client with
client, err := storage.NewClient(ctx, option.WithoutAuthentication())
Buckets
A Google Cloud Storage bucket is a collection of objects. To work with a
bucket, make a bucket handle:
bkt := client.Bucket(bucketName)
A handle is a reference to a bucket. You can have a handle even if the
bucket doesn't exist yet. To create a bucket in Google Cloud Storage,
call Create on the handle:
if err := bkt.Create(ctx, projectID, nil); err != nil {
// TODO: Handle error.
}
Note that although buckets are associated with projects, bucket names are
global across all projects.
Each bucket has associated metadata, represented in this package by
BucketAttrs. The third argument to BucketHandle.Create allows you to set
the initial BucketAttrs of a bucket. To retrieve a bucket's attributes, use
Attrs:
attrs, err := bkt.Attrs(ctx)
if err != nil {
// TODO: Handle error.
}
fmt.Printf("bucket %s, created at %s, is located in %s with storage class %s\n",
attrs.Name, attrs.Created, attrs.Location, attrs.StorageClass)
Objects
An object holds arbitrary data as a sequence of bytes, like a file. You
refer to objects using a handle, just as with buckets, but unlike buckets
you don't explicitly create an object. Instead, the first time you write
to an object it will be created. You can use the standard Go io.Reader
and io.Writer interfaces to read and write object data:
obj := bkt.Object("data")
// Write something to obj.
// w implements io.Writer.
w := obj.NewWriter(ctx)
// Write some text to obj. This will either create the object or overwrite whatever is there already.
if _, err := fmt.Fprintf(w, "This object contains text.\n"); err != nil {
// TODO: Handle error.
}
// Close, just like writing a file.
if err := w.Close(); err != nil {
// TODO: Handle error.
}
// Read it back.
r, err := obj.NewReader(ctx)
if err != nil {
// TODO: Handle error.
}
defer r.Close()
if _, err := io.Copy(os.Stdout, r); err != nil {
// TODO: Handle error.
}
// Prints "This object contains text."
Objects also have attributes, which you can fetch with Attrs:
objAttrs, err := obj.Attrs(ctx)
if err != nil {
// TODO: Handle error.
}
fmt.Printf("object %s has size %d and can be read using %s\n",
objAttrs.Name, objAttrs.Size, objAttrs.MediaLink)
Listing objects
Listing objects in a bucket is done with the Bucket.Objects method:
query := &storage.Query{Prefix: ""}
var names []string
it := bkt.Objects(ctx, query)
for {
attrs, err := it.Next()
if err == iterator.Done {
break
}
if err != nil {
log.Fatal(err)
}
names = append(names, attrs.Name)
}
Objects are listed lexicographically by name. To filter objects
lexicographically, Query.StartOffset and/or Query.EndOffset can be used:
query := &storage.Query{
Prefix: "",
StartOffset: "bar/", // Only list objects lexicographically >= "bar/"
EndOffset: "foo/", // Only list objects lexicographically < "foo/"
}
// ... as before
If only a subset of object attributes is needed when listing, specifying this
subset using Query.SetAttrSelection may speed up the listing process:
query := &storage.Query{Prefix: ""}
query.SetAttrSelection([]string{"Name"})
// ... as before
ACLs
Both objects and buckets have ACLs (Access Control Lists). An ACL is a list of
ACLRules, each of which specifies the role of a user, group or project. ACLs
are suitable for fine-grained control, but you may prefer using IAM to control
access at the project level (see
https://cloud.google.com/storage/docs/access-control/iam).
To list the ACLs of a bucket or object, obtain an ACLHandle and call its List method:
acls, err := obj.ACL().List(ctx)
if err != nil {
// TODO: Handle error.
}
for _, rule := range acls {
fmt.Printf("%s has role %s\n", rule.Entity, rule.Role)
}
You can also set and delete ACLs.
Conditions
Every object has a generation and a metageneration. The generation changes
whenever the content changes, and the metageneration changes whenever the
metadata changes. Conditions let you check these values before an operation;
the operation only executes if the conditions match. You can use conditions to
prevent race conditions in read-modify-write operations.
For example, say you've read an object's metadata into objAttrs. Now
you want to write to that object, but only if its contents haven't changed
since you read it. Here is how to express that:
w = obj.If(storage.Conditions{GenerationMatch: objAttrs.Generation}).NewWriter(ctx)
// Proceed with writing as above.
Signed URLs
You can obtain a URL that lets anyone read or write an object for a limited time.
You don't need to create a client to do this. See the documentation of
SignedURL for details.
url, err := storage.SignedURL(bucketName, "shared-object", opts)
if err != nil {
// TODO: Handle error.
}
fmt.Println(url)
Post Policy V4 Signed Request
A type of signed request that allows uploads through HTML forms directly to Cloud Storage with
temporary permission. Conditions can be applied to restrict how the HTML form is used and exercised
by a user.
For more information, please see https://cloud.google.com/storage/docs/xml-api/post-object as well
as the documentation of GenerateSignedPostPolicyV4.
pv4, err := storage.GenerateSignedPostPolicyV4(bucketName, objectName, opts)
if err != nil {
// TODO: Handle error.
}
fmt.Printf("URL: %s\nFields; %v\n", pv4.URL, pv4.Fields)
Errors
Errors returned by this client are often of the type [`googleapi.Error`](https://godoc.org/google.golang.org/api/googleapi#Error).
These errors can be introspected for more information by type asserting to the richer `googleapi.Error` type. For example:
if e, ok := err.(*googleapi.Error); ok {
if e.Code == 409 { ... }
}

# Testing Code that depends on Go Client Libraries
The Go client libraries generated as a part of `cloud.google.com/go` all take
the approach of returning concrete types instead of interfaces. That way, new
fields and methods can be added to the libraries without breaking users. This
document will go over some patterns that can be used to test code that depends
on the Go client libraries.
## Testing gRPC services using fakes
*Note*: You can see the full
[example code using a fake here](https://github.com/googleapis/google-cloud-go/tree/master/internal/examples/fake).
The clients found in `cloud.google.com/go` are gRPC based, with a couple of
notable exceptions being the [`storage`](https://pkg.go.dev/cloud.google.com/go/storage)
and [`bigquery`](https://pkg.go.dev/cloud.google.com/go/bigquery) clients.
Interactions with gRPC services can be faked by serving up your own in-memory
server within your test. One benefit of using this approach is that you don’t
need to define an interface in your runtime code; you can keep using
concrete struct types. You instead define a fake server in your test code. For
example, take a look at the following function:
```go
import (
"context"
"fmt"
"log"
"os"
translate "cloud.google.com/go/translate/apiv3"
"github.com/googleapis/gax-go/v2"
translatepb "google.golang.org/genproto/googleapis/cloud/translate/v3"
)
func TranslateTextWithConcreteClient(client *translate.TranslationClient, text string, targetLang string) (string, error) {
ctx := context.Background()
log.Printf("Translating %q to %q", text, targetLang)
req := &translatepb.TranslateTextRequest{
Parent: fmt.Sprintf("projects/%s/locations/global", os.Getenv("GOOGLE_CLOUD_PROJECT")),
TargetLanguageCode: "en-US",
Contents: []string{text},
}
resp, err := client.TranslateText(ctx, req)
if err != nil {
return "", fmt.Errorf("unable to translate text: %v", err)
}
translations := resp.GetTranslations()
if len(translations) != 1 {
return "", fmt.Errorf("expected only one result, got %d", len(translations))
}
return translations[0].TranslatedText, nil
}
```
Here is an example of what a fake server implementation would look like for
faking the interactions above:
```go
import (
"context"
translatepb "google.golang.org/genproto/googleapis/cloud/translate/v3"
)
type fakeTranslationServer struct {
translatepb.UnimplementedTranslationServiceServer
}
func (f *fakeTranslationServer) TranslateText(ctx context.Context, req *translatepb.TranslateTextRequest) (*translatepb.TranslateTextResponse, error) {
resp := &translatepb.TranslateTextResponse{
Translations: []*translatepb.Translation{
&translatepb.Translation{
TranslatedText: "Hello World",
},
},
}
return resp, nil
}
```
All of the generated protobuf code found in [google.golang.org/genproto](https://pkg.go.dev/google.golang.org/genproto)
contains a similar `package.UnimplmentedFooServer` type that is useful for
creating fakes. By embedding the unimplemented server in the
`fakeTranslationServer`, the fake will “inherit” all of the RPCs the server
exposes. Then, by providing our own `fakeTranslationServer.TranslateText`
method you can “override” the default unimplemented behavior of the one RPC that
you would like to be faked.
The test itself does require a little bit of setup: start up a `net.Listener`,
register the server, and tell the client library to call the server:
```go
import (
"context"
"net"
"testing"
translate "cloud.google.com/go/translate/apiv3"
"google.golang.org/api/option"
translatepb "google.golang.org/genproto/googleapis/cloud/translate/v3"
"google.golang.org/grpc"
)
func TestTranslateTextWithConcreteClient(t *testing.T) {
ctx := context.Background()
// Setup the fake server.
fakeTranslationServer := &fakeTranslationServer{}
l, err := net.Listen("tcp", "localhost:0")
if err != nil {
t.Fatal(err)
}
gsrv := grpc.NewServer()
translatepb.RegisterTranslationServiceServer(gsrv, fakeTranslationServer)
fakeServerAddr := l.Addr().String()
go func() {
if err := gsrv.Serve(l); err != nil {
panic(err)
}
}()
// Create a client.
client, err := translate.NewTranslationClient(ctx,
option.WithEndpoint(fakeServerAddr),
option.WithoutAuthentication(),
option.WithGRPCDialOption(grpc.WithInsecure()),
)
if err != nil {
t.Fatal(err)
}
// Run the test.
text, err := TranslateTextWithConcreteClient(client, "Hola Mundo", "en-US")
if err != nil {
t.Fatal(err)
}
if text != "Hello World" {
t.Fatalf("got %q, want Hello World", text)
}
}
```

[example code using a mock here](https://github.com/googleapis/google-cloud-go/tree/master/internal/examples/mock).
When mocking code you need to work with interfaces. Let’s create an interface
for the `cloud.google.com/go/translate/apiv3` client used in the
`TranslateTextWithConcreteClient` function mentioned in the previous section.
The `translate.Client` has over a dozen methods but this code only uses one of
them. Here is an interface that satisfies the interactions of the
`translate.Client` in this function.
```go
type TranslationClient interface {
TranslateText(ctx context.Context, req *translatepb.TranslateTextRequest, opts ...gax.CallOption) (*translatepb.TranslateTextResponse, error)
}
```
Now that we have an interface that satisfies the method being used we can
rewrite the function signature to take the interface instead of the concrete
type.
```go
func TranslateTextWithInterfaceClient(client TranslationClient, text string, targetLang string) (string, error) {
// ...
}
```
This allows a real `translate.Client` to be passed to the method in production
and for a mock implementation to be passed in during testing. This pattern can
be applied to any Go code, not just `cloud.google.com/go`. This is because
interfaces in Go are implicitly satisfied. Structs in the client libraries can
implicitly implement interfaces defined in your codebase. Let’s take a look at
what it might look like to define a lightweight mock for the `TranslationClient`
interface.
```go
import (
"context"
"testing"
"github.com/googleapis/gax-go/v2"
translatepb "google.golang.org/genproto/googleapis/cloud/translate/v3"
)
type mockClient struct{}
func (*mockClient) TranslateText(_ context.Context, req *translatepb.TranslateTextRequest, opts ...gax.CallOption) (*translatepb.TranslateTextResponse, error) {
resp := &translatepb.TranslateTextResponse{
Translations: []*translatepb.Translation{
&translatepb.Translation{
TranslatedText: "Hello World",
},
},
}
return resp, nil
}
func TestTranslateTextWithAbstractClient(t *testing.T) {
client := &mockClient{}
text, err := TranslateTextWithInterfaceClient(client, "Hola Mundo", "en-US")
if err != nil {
t.Fatal(err)
}
if text != "Hello World" {
t.Fatalf("got %q, want Hello World", text)
}
}
```
If you prefer to not write your own mocks there are mocking frameworks such as
[golang/mock](https://github.com/golang/mock) which can generate mocks for you
from an interface. As a word of caution though, try to not
[overuse mocks](https://testing.googleblog.com/2013/05/testing-on-toilet-dont-overuse-mocks.html).
## Testing using emulators
Some of the client libraries provided in `cloud.google.com/go` support running
against a service emulator. The concept is similar to that of using fakes,
mentioned above, but the server is managed for you. You just need to start it up
and instruct the client library to talk to the emulator by setting a service
specific emulator environment variable. Current services/environment-variables
are:
- bigtable: `BIGTABLE_EMULATOR_HOST`
- datastore: `DATASTORE_EMULATOR_HOST`
- firestore: `FIRESTORE_EMULATOR_HOST`
- pubsub: `PUBSUB_EMULATOR_HOST`
- spanner: `SPANNER_EMULATOR_HOST`
- storage: `STORAGE_EMULATOR_HOST`
- Although the storage client supports an emulator environment variable there is no official emulator provided by gcloud.
For more information on emulators please refer to the
[gcloud documentation](https://cloud.google.com/sdk/gcloud/reference/beta/emulators).

# fastcache - fast thread-safe inmemory cache for big number of entries in Go
### Features
* Fast. Performance scales on multi-core CPUs. See benchmark results below.
* Thread-safe. Concurrent goroutines may read and write into a single
cache instance.
* The fastcache is designed for storing big number of entries without
[GC overhead](https://syslog.ravelin.com/further-dangers-of-large-heaps-in-go-7a267b57d487).
* Fastcache automatically evicts old entries when reaching the maximum cache size
set on its creation.
* [Simple API](http://godoc.org/github.com/VictoriaMetrics/fastcache).
* Simple source code.
* Cache may be [saved to file](https://godoc.org/github.com/VictoriaMetrics/fastcache#Cache.SaveToFile)
and [loaded from file](https://godoc.org/github.com/VictoriaMetrics/fastcache#LoadFromFile).
* Works on [Google AppEngine](https://cloud.google.com/appengine/docs/go/).
### Benchmarks
`Fastcache` performance is compared with [BigCache](https://github.com/allegro/bigcache), standard Go map
and [sync.Map](https://golang.org/pkg/sync/#Map).

```
`MB/s` column here actually means `millions of operations per second`.
As you can see, `fastcache` is faster than the `BigCache` in all the cases.
`fastcache` is faster than the standard Go map and `sync.Map` on workloads
with inserts.
### Limitations
* Keys and values must be byte slices. Other types must be marshaled before
storing them in the cache.
* Big entries with sizes exceeding 64KB must be stored via [distinct API](http://godoc.org/github.com/VictoriaMetrics/fastcache#Cache.SetBig).
* There is no cache expiration. Entries are evicted from the cache only
on cache size overflow. Entry deadline may be stored inside the value in order
to implement cache expiration.
### Architecture details
The cache uses ideas from [BigCache](https://github.com/allegro/bigcache):
* The cache consists of many buckets, each with its own lock.
This helps scaling the performance on multi-core CPUs, since multiple
CPUs may concurrently access distinct buckets.
* Each bucket consists of a `hash(key) -> (key, value) position` map
and 64KB-sized byte slices (chunks) holding encoded `(key, value)` entries.
Each bucket contains only `O(chunksCount)` pointers. For instance, 64GB cache
would contain ~1M pointers, while similarly-sized `map[string][]byte`
would contain ~1B pointers for short keys and values. This would lead to
[huge GC overhead](https://syslog.ravelin.com/further-dangers-of-large-heaps-in-go-7a267b57d487).
64KB-sized chunks reduce memory fragmentation and the total memory usage comparing
to a single big chunk per bucket.
Chunks are allocated off-heap if possible. This reduces total memory usage because
GC collects unused memory more frequently without the need in `GOGC` tweaking.
### Users
* `Fastcache` has been extracted from [VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics) sources.
See [this article](https://medium.com/devopslinks/victoriametrics-creating-the-best-remote-storage-for-prometheus-5d92d66787ac)
for more info about `VictoriaMetrics`.
### FAQ
#### What is the difference between `fastcache` and other similar caches like [BigCache](https://github.com/allegro/bigcache) or [FreeCache](https://github.com/coocood/freecache)?
* `Fastcache` is faster. See benchmark results above.
* `Fastcache` uses less memory due to lower heap fragmentation. This allows
saving many GBs of memory on multi-GB caches.
* `Fastcache` API [is simpler](http://godoc.org/github.com/VictoriaMetrics/fastcache).
The API is designed to be used in zero-allocation mode.
#### Why `fastcache` doesn't support cache expiration?
Because we don't need cache expiration in [VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics).
Cached entries inside `VictoriaMetrics` never expire. They are automatically evicted on cache size overflow.
It is easy to implement cache expiration on top of `fastcache` by caching values
with marshaled deadlines and verifying deadlines after reading these values
from the cache.
#### Why `fastcache` doesn't support advanced features such as [thundering herd protection](https://en.wikipedia.org/wiki/Thundering_herd_problem) or callbacks on entries' eviction?
Because these features would complicate the code and would make it slower.
`Fastcache` source code is simple - just copy-paste it and implement the feature you want
on top of it.

/*
Package fasthttp provides fast HTTP server and client API.
Fasthttp provides the following features:
* Optimized for speed. Easily handles more than 100K qps and more than 1M
concurrent keep-alive connections on modern hardware.
* Optimized for low memory usage.
* Easy 'Connection: Upgrade' support via RequestCtx.Hijack.
* Server supports requests' pipelining. Multiple requests may be read from
a single network packet and multiple responses may be sent in a single
network packet. This may be useful for highly loaded REST services.
* Server provides the following anti-DoS limits:
* The number of concurrent connections.
* The number of concurrent connections per client IP.
* The number of requests per connection.
* Request read timeout.
* Response write timeout.
* Maximum request header size.
* Maximum request body size.
* Maximum request execution time.
* Maximum keep-alive connection lifetime.
* Early filtering out non-GET requests.
* A lot of additional useful info is exposed to request handler:
* Server and client address.
* Per-request logger.
* Unique request id.
* Request start time.
* Connection start time.
* Request sequence number for the current connection.
* Client supports automatic retry on idempotent requests' failure.
* Fasthttp API is designed with the ability to extend existing client
and server implementations or to write custom client and server
implementations from scratch.

// Dial dials the given TCP addr using tcp4.
//
// This function has the following additional features comparing to net.Dial:
//
// * It reduces load on DNS resolver by caching resolved TCP addressed
// for DefaultDNSCacheDuration.
// * It dials all the resolved TCP addresses in round-robin manner until
// connection is established. This may be useful if certain addresses
// are temporarily unreachable.
// * It returns ErrDialTimeout if connection cannot be established during
// DefaultDialTimeout seconds. Use DialTimeout for customizing dial timeout.
//
// This dialer is intended for custom code wrapping before passing
// to Client.Dial or HostClient.Dial.
//
// For instance, per-host counters and/or limits may be implemented
// by such wrappers.
//
// The addr passed to the function must contain port. Example addr values:
//
// * foobar.baz:443
// * foo.bar:80
// * aaa.com:8080
