 * 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).

-# 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).

-> changes where necessary.
->
-> **Stable status**: the API is mature and ready for production use. We will

-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).

-/*
-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

-This directory contains internal code for cloud.google.com/go packages.
-
-## .repo-metadata-full.json
-
-`.repo-metadata-full.json` contains metadata about the packages in this repo. It
-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.

-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its

-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,

-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-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)
-        }
-}
-```
-
-## Testing using mocks
-
-*Note*: You can see the full
-[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.
