+## v1.79.x long-time support release (LTS)
+
+## [v1.79.6](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.79.6)
+
+Released at 11-12-2022
+
+* SECURITY: update Go builder from v1.19.3 to v1.19.4. See [the changelog](https://github.com/golang/go/issues?q=milestone%3AGo1.19.4+label%3ACherryPickApproved).
+* SECURITY: update base Docker image for VictoriaMetrics components from Alpine 3.16.2 to Alpine v3.17.0. See [the changelog](https://alpinelinux.org/releases/).
+
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): fix the `The request did not have a subscription or a valid tenant level resource provider` error when discovering Azure targets with [azure_sd_configs](https://docs.victoriametrics.com/sd_configs.html#azure_sd_configs). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3247).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly discover GCE zones when `filter` option is set at [gce_sd_configs](https://docs.victoriametrics.com/sd_configs.html#gce_sd_configs). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3202).
+* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): properly specify rule evaluation step during the [replay mode](https://docs.victoriametrics.com/vmalert.html#rules-backfilling). The `step` value was previously overriden by `-datasource.queryStep` command-line flag.
+* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): properly return the error message from remote-write failures. Before, error was ignored and only `vmalert_remotewrite_errors_total` was incremented.
+* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly return an empty result from [limit_offset](https://docs.victoriametrics.com/MetricsQL.html#limit_offset) if the `offset` arg exceeds the number of inner time series. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3312).
+
+## [v1.79.5](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.79.5)
+
+Released at 10-11-2022
+
+**v1.79.x is a line of LTS releases (e.g. long-time support). It contains important up-to-date bugfixes.
+The v1.79.x line will be supported for at least 12 months since [v1.79.0](https://docs.victoriametrics.com/CHANGELOG.html#v1790) release**
+
+**Update note 1:** [vmalert](https://docs.victoriametrics.com/vmalert.html): the `crlfEscape` [template function](https://docs.victoriametrics.com/vmalert.html#template-functions) becames obsolete starting from this release. It can be safely removed from alerting templates, since `\n` chars are properly escaped with other `*Escape` functions now. See [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139) and [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/890) issue for details.
+
+* SECURITY: update Go builder to v1.19.3. This fixes [CVE-2022 security issue](https://github.com/golang/go/issues/56328). See [the changelog](https://github.com/golang/go/issues?q=milestone%3AGo1.19.3+label%3ACherryPickApproved).
+
+* BUGFIX: properly register new time series in per-day inverted index if they were ingested during the last 10 seconds of the day. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3309). Thanks to @lmarszal for the bugreport and for the [initial fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3320).
+* BUGFIX: properly accept [OpenTSDB telnet put lines](https://docs.victoriametrics.com/#sending-data-via-telnet-put-protocol) without tags without the need to specify the trailing whitespace. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3290).
+* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly merge buckets with identical `le` values, but with different string representation of these values when calculating [histogram_quantile](https://docs.victoriametrics.com/MetricsQL.html#histogram_quantile) and [histogram_share](https://docs.victoriametrics.com/MetricsQL.html#histogram_share). For example, `http_request_duration_seconds_bucket{le="5"}` and `http_requests_duration_seconds_bucket{le="5.0"}`. Such buckets may be returned from distinct targets. Thanks to @647-coder for the [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3225).
+* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): change severity level for log messages about failed attempts for sending data to remote storage from `error` to `warn`. The message for about all failed send attempts remains at `error` severity level.
+* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): properly escape string passed to `quotesEscape` [template function](https://docs.victoriametrics.com/vmalert.html#template-functions), so it can be safely embedded into JSON string. This makes obsolete the `crlfEscape` function. See [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139) and [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/890) issue.
+* BUGFIX: `vmselect`: expose missing metric `vm_cache_size_max_bytes{type="promql/rollupResult"}` . This metric is used for monitoring rollup cache usage with the query `vm_cache_size_bytes{type="promql/rollupResult"} / vm_cache_size_max_bytes{type="promql/rollupResult"}` in the same way as this is done for other cache types.
+
+
+## [v1.79.4](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.79.4)
+
+Released at 07-10-2022
+
+**v1.79.x is a line of LTS releases (e.g. long-time support). It contains important up-to-date bugfixes.
+The v1.79.x line will be supported for at least 12 months since [v1.79.0](https://docs.victoriametrics.com/CHANGELOG.html#v1790) release**
+
+**Update note 1:** [vmalert](https://docs.victoriametrics.com/vmalert.html) changes default value for command-line flag `-datasource.queryStep` from `0s` to `5m`. The change supposed to improve reliability of the rules evaluation when evaluation interval is lower than scraping interval.
+
+* FEATURE: expose `vmagent_remotewrite_queues` metric and use it in alerting rules in order to improve the detection of remote storage connection saturation. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2871).
+
+* BUGFIX: do not export stale metrics via [/federate api](https://docs.victoriametrics.com/#federation) after the staleness markers. Previously such metrics were exported with `NaN` values. this could break some setups. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3185).
+* BUGFIX: [vmauth](https://docs.victoriametrics.com/vmauth.html): properly handle request paths ending with `/` such as `/vmui/`. Previously `vmui` was dropping the traling `/`, which could prevent from using `vmui` via `vmauth`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1752).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly encode query params for aws signed requests, use `%20` instead of `+` as api requires. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3171).
+* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly calculate `rate_over_sum(m[d])` as `sum_over_time(m[d])/d`. Previously the `sum_over_time(m[d])` could be improperly divided by smaller than `d` time range. See [rate_over_sum() docs](https://docs.victoriametrics.com/MetricsQL.html#rate_over_sum) and [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3045).
+* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly calculate `increase(m[d])` over slow-changing counters with values smaller than 100. Previously [increase](https://docs.victoriametrics.com/MetricsQL.html#increase) could return unexpectedly big results in this case. See [the related issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/962) and [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3163).
+* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): ignore empty series when applying [limit_offset](https://docs.victoriametrics.com/MetricsQL.html#limit_offset). It should improve queries with additional filters by value in expressions like `limit_offset(1,1, foo > 1)`.
+* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly calculate [quantiles_over_time](https://docs.victoriametrics.com/MetricsQL.html#quantiles_over_time) when the lookbehind window contains only a single sample. Previously an empty result was incorrectly returned in this case.
+* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix `RangeError: Maximum call stack size exceeded` error when the query returns too many data points at `Table` view. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3092/files).
+* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): re-evaluate annotations per each alert evaluation. Previously, annotations were evaluated only on alert's value change. This could result in stale annotations in some cases described in [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3119).
+* BUGFIX: prevent from excessive CPU usage when the storage enters [read-only mode](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#readonly-mode). The previous fix in [v1.79.3](https://docs.victoriametrics.com/CHANGELOG.html#v1793) wasn't complete.
+* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): change default value for command-line flag `-datasource.queryStep` from `0s` to `5m`. Param `step` is added by vmalert to every rule evaluation request sent to datasource. Before this change, `step` was equal to group's evaluation interval by default. Param `step` for instant queries defines how far VM can look back for the last written data point. The change supposed to improve reliability of the rules evaluation when evaluation interval is lower than scraping interval.
+* BUGFIX: properly calculate `vm_rows_scanned_per_query` histogram exported at `/metrics` page of `vmselect` and single-node VictoriaMetrics. Previously it could return misleadingly high numbers for [rollup functions](https://docs.victoriametrics.com/MetricsQL.html#rollup-functions), which scan only a few samples on the provided lookbehind window in square brackets. For example, `increase(m[1d])` always scans only 2 rows (aka `raw samples`) per each returned time series.
+
+
+## [v1.79.3](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.79.3)
+
+Released at 30-08-2022
+
+**v1.79.x is a line of LTS releases (e.g. long-time support). It contains important up-to-date bugfixes.
+The v1.79.x line will be supported for at least 12 months since [v1.79.0](https://docs.victoriametrics.com/CHANGELOG.html#v1790) release**
+
+* SECURITY: [vmalert](https://docs.victoriametrics.com/vmalert.html): do not expose `-remoteWrite.url`, `-remoteRead.url` and `-datasource.url` command-line flag values in logs and at `http://vmalert:8880/flags` page by default, since they may contain sensitive data such as auth keys. This aligns `vmalert` behaviour with [vmagent](), which doesn't expose `-remoteWrite.url` command-line flag value in logs and at `http://vmagent:8429/flags` page by default. Specify `-remoteWrite.showURL`, `-remoteRead.showURL` and `-datasource.showURL` command-line flags for showing values for the corresponding `-*.url` flags in logs. Thanks to @mble for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2965).
+* SECURITY: upgrade base docker image (alpine) from 3.16.1 to 3.16.2. See [alpine 3.16.2 release notes](https://alpinelinux.org/posts/Alpine-3.13.12-3.14.8-3.15.6-3.16.2-released.html).
+
+* BUGFIX: prevent from excess CPU usage when the storage enters [read-only mode](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#readonly-mode).
+* BUGFIX: improve performance for requests to [/api/v1/labels](https://docs.victoriametrics.com/url-examples.html#apiv1labels) and [/api/v1/label/.../values](https://docs.victoriametrics.com/url-examples.html#apiv1labelvalues) when the filter in the `match[]` query arg matches small number of time series.

+## [v1.79.2](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.79.2)
+
+Released at 08-08-2022
+
+**v1.79.x is a line of LTS releases (e.g. long-time support). It contains important up-to-date bugfixes.
+The v1.79.x line will be supported for at least 12 months since [v1.79.0](https://docs.victoriametrics.com/CHANGELOG.html#v1790) release**
+
+* BUGFIX: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): fix potential panic in [multi-level cluster setup](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#multi-level-cluster-setup) when top-level `vmselect` is configured with `-replicationFactor` bigger than 1. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2961).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly handle custom `endpoint` value in [ec2_sd_configs](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#ec2_sd_config). It was ignored since [v1.77.0](https://docs.victoriametrics.com/CHANGELOG.html#v1770) because of a bug in the implementation of [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1287).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): add missing `__meta_kubernetes_ingress_class_name` meta-label for `role: ingress` service discovery in Kubernetes. See [this commit from Prometheus](https://github.com/prometheus/prometheus/commit/7e65ad3e432bd2837c17e3e63e85dcbcc30f4a8a).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): allow stale responses from Consul service discovery (aka [consul_sd_configs](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#consul_sd_config)) by default in the same way as Prometheus does. This should reduce load on Consul when discovering big number of targets. Stale responses can be disabled by specifying `allow_stale: false` option in `consul_sd_config`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2940).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): [dockerswarm_sd_configs](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#dockerswarm_sd_config): properly set `__meta_dockerswarm_container_label_*` labels instead of `__meta_dockerswarm_task_label_*` labels as Prometheus does. See [this issue](https://github.com/prometheus/prometheus/issues/9187).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): set `up` metric to `0` for partial scrapes in [stream parsing mode](https://docs.victoriametrics.com/vmagent.html#stream-parsing-mode). Previously the `up` metric was set to `1` when at least a single metric has been scraped before the error. This aligns the behaviour of `vmselect` with Prometheus.
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): restart all the scrape jobs during [config reload](https://docs.victoriametrics.com/vmagent.html#configuration-update) after `global` section is changed inside `-promscrape.config`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2884).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly assume role with AWS ECS credentials. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2875). Thanks to @transacid for [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2876).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): do not split regex in [relabeling rules](https://docs.victoriametrics.com/vmagent.html#relabeling) into multiple lines if it contains groups. This fixes [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2928).
+* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): return series from `q1` if `q2` doesn't return matching time series in the query `q1 ifnot q2`. Previously series from `q1` weren't returned in this case.
+* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): properly show date picker at `Table` tab. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2874).
+* BUGFIX: properly generate http redirects if `-http.pathPrefix` command-line flag is set. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2918).

 **Update note 1:** this release introduces backwards-incompatible changes to `vm_partial_results_total` metric by changing its labels to be consistent with `vm_requests_total` metric. If you use alerting rules or Grafana dashboards, which rely on this metric, then they must be updated. The official dashboards for VictoriaMetrics don't use this metric.
 
 **Update note 2:** [vmalert](https://docs.victoriametrics.com/vmalert.html) adds `/vmalert/` prefix to [web urls](https://docs.victoriametrics.com/vmalert.html#web) according to [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2825). This may affect `vmalert` instances with non-empty `-http.pathPrefix` command-line flag. After the update, configuring this flag is no longer needed. Here's [why](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2799#issuecomment-1171392005).

+1a. Document all the changes for new release in [CHANGELOG.md](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/CHANGELOG.md).
+1b. Add `(available starting from v1.xx.y)` line to feature docs introduced in the upcoming release.
 2. Create the following release tags:
    * `git tag -s v1.xx.y` in `master` branch
    * `git tag -s v1.xx.y-cluster` in `cluster` branch
    * `git tag -s v1.xx.y-enterprise` in `enterprise` branch
    * `git tag -s v1.xx.y-enterprise-cluster` in `enterprise-cluster` branch
-3. Run `TAG=v1.xx.y make publish-release`. It will create `*.tar.gz` release archives with the corresponding `_checksums.txt` files inside `bin` directory and publish Docker images for the given `TAG`, `TAG-cluster`, `TAG-enterprise` and `TAG-enterprise-cluster`.
-4. Push release tags to <https://github.com/VictoriaMetrics/VictoriaMetrics> : `git push origin v1.xx.y` and `git push origin v1.xx.y-cluster`. Do not push `-enterprise` tags to public repository.
-5. Go to <https://github.com/VictoriaMetrics/VictoriaMetrics/releases> , create new release from the pushed tag on step 4 and upload `*.tar.gz` archive with the corresponding `_checksums.txt` from step 3.
-6. Copy the [CHANGELOG](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/CHANGELOG.md) for this release to [releases](https://github.com/VictoriaMetrics/VictoriaMetrics/releases) page.
-7. Bump version of the VictoriaMetrics cluster setup in for [sandbox environment](https://github.com/VictoriaMetrics/ops/blob/main/sandbox/manifests/benchmark-vm/vmcluster.yaml)
-by [opening and merging PR](https://github.com/VictoriaMetrics/ops/pull/58).
+3. Run `TAG=v1.xx.y make publish-release`. This command performs the following tasks:
+   a) Build and package binaries in `*.tar.gz` release archives with the corresponding `_checksums.txt` files inside `bin` directory.
+      This step can be run manually with the command `make release` from the needed git tag.
+   b) Build and publish [multi-platform Docker images](https://docs.docker.com/build/buildx/multiplatform-images/)
+      for the given `TAG`, `TAG-cluster`, `TAG-enterprise` and `TAG-enterprise-cluster`.
+      The multi-platform Docker image is built for the following platforms:
+      * linux/amd64
+      * linux/arm64
+      * linux/arm
+      * linux/ppc64le
+      * linux/386
+      This step can be run manually with the command `make publish` from the needed git tag.
+4. Push the tags created `v1.xx.y` and `v1.xx.y-cluster` at step 2 to public GitHub repository at https://github.com/VictoriaMetrics/VictoriaMetrics .
+   **Important note:** do not push enteprise tags to public GitHub repository - they must be pushed only to private repository.
+5. Run `TAG=v1.xx.yy make github-create-release github-upload-assets`. This command performs the following tasks:
+   a) Create draft GitHub release with the name `TAG`. This step can be run manually
+      with the command `TAG=v1.xx.y make github-create-release`.
+      The release id is stored at `/tmp/vm-github-release` file.
+   b) Upload all the binaries and checksums created at step `3a` to that release.
+      This step can be run manually with the command `make github-upload-assets`.
+      It is expected that the needed release id is stored at `/tmp/vm-github-release` file,
+      which must be created at the step `a`.
+      If the upload process is interrupted by any reason, then the following recovery steps must be performed:
+      - To delete the created draft release by running the command `make github-delete-release`.
+        This command expects that the id of the release to delete is located at `/tmp/vm-github-release`
+        file created at the step `a`.
+      - To run the command `TAG=v1.xx.y make github-create-release github-upload-assets`, so new release is created
+        and all the needed assets are re-uploaded to it.
+6. Go to <https://github.com/VictoriaMetrics/VictoriaMetrics/releases> and verify that draft release with the name `TAG` has been created
+   and this release contains all the needed binaries and checksums.
+7. Update the release description with the [CHANGELOG](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/CHANGELOG.md) for this release.
+8. Remove the `draft` checkbox for the `TAG` release and manually publish it.
+9. Bump version of the VictoriaMetrics cluster in the [sandbox environment](https://github.com/VictoriaMetrics/ops/blob/main/sandbox/manifests/benchmark-vm/vmcluster.yaml)

-# 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 PR.
-
-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](https://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
-- Pub/Sub Lite 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_API_KEY`: API key for using the Translate API created above.
-
-As part of the setup that follows, the following variables will be configured:
-
-- `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_BIGTABLE_KEYRING`: The full name of the keyring for the bigtable tests,
-in the form
-"projects/P/locations/L/keyRings/R". The creation of this is described below. Expected to be single region.
-- `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-<numeric 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
-$ export MY_SINGLE_LOCATION=us-central1
-# 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 $GCLOUD_TESTS_GOLANG_KEYRING/cryptoKeys/key1
-
-# Create KMS Key in one region for Bigtable
-$ gcloud kms keyrings create $MY_KEYRING --location $MY_SINGLE_LOCATION
-$ gcloud kms keys create key1 --keyring $MY_KEYRING --location $MY_SINGLE_LOCATION --purpose encryption
-# Sets the GCLOUD_TESTS_BIGTABLE_KEYRING environment variable.
-$ export GCLOUD_TESTS_BIGTABLE_KEYRING=projects/$GCLOUD_TESTS_GOLANG_PROJECT_ID/locations/$MY_SINGLE_LOCATION/keyRings/$MY_KEYRING
-# Create a service agent, https://cloud.google.com/bigtable/docs/use-cmek#gcloud:
-$ gcloud beta services identity create \
-    --service=bigtableadmin.googleapis.com \
-    --project $GCLOUD_TESTS_GOLANG_PROJECT_ID
-# Note the service agent email for the agent created.
-$ export SERVICE_AGENT_EMAIL=<service agent email, from last step>
-
-# Authorizes Google Cloud Bigtable to encrypt and decrypt using key1
-$ gcloud kms keys add-iam-policy-binding key1 \
-    --keyring $MY_KEYRING \
-    --location $MY_SINGLE_LOCATION \
-    --role roles/cloudkms.cryptoKeyEncrypterDecrypter \
-    --member "serviceAccount:$SERVICE_AGENT_EMAIL" \
-    --project $GCLOUD_TESTS_GOLANG_PROJECT_ID
-```
-
-It may be useful to add exports to your shell initialization for future use.
-For instance, in `.zshrc`:
-
-```sh
-#### START GO SDK Test Variables
-# Developers Console project's ID (e.g. bamboo-shift-455) for the general project.
-export GCLOUD_TESTS_GOLANG_PROJECT_ID=your-project
-
-# The path to the JSON key file of the general project's service account.
-export GCLOUD_TESTS_GOLANG_KEY=~/directory/your-project-abcd1234.json
-
-# Developers Console project's ID (e.g. doorway-cliff-677) for the Firestore project.
-export GCLOUD_TESTS_GOLANG_FIRESTORE_PROJECT_ID=your-firestore-project
-
-# The path to the JSON key file of the Firestore project's service account.
-export GCLOUD_TESTS_GOLANG_FIRESTORE_KEY=~/directory/your-firestore-project-abcd1234.json
-
-# The full name of the keyring for the tests, in the form "projects/P/locations/L/keyRings/R".
-# The creation of this is described below.
-export MY_KEYRING=my-golang-sdk-test
-export MY_LOCATION=global
-export GCLOUD_TESTS_GOLANG_KEYRING=projects/$GCLOUD_TESTS_GOLANG_PROJECT_ID/locations/$MY_LOCATION/keyRings/$MY_KEYRING
-
-# API key for using the Translate API.
-export GCLOUD_TESTS_API_KEY=abcdefghijk123456789
-
-# Compute Engine zone. (https://cloud.google.com/compute/docs/regions-zones)
-export GCLOUD_TESTS_GOLANG_ZONE=your-chosen-region
-#### END GO SDK Test Variables
-```
-
-#### Running
-
-Once you've done the necessary setup, you can run the integration tests by
-running:
-
-``` sh
-$ go test -v ./...
-```
-
-Note that the above command will not run the tests in other modules. To run
-tests on other modules, first navigate to the appropriate
-subdirectory. For instance, to run only the tests for datastore:
-``` sh
-$ cd datastore
-$ go test -v ./...
-```
-
-#### 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
-
-[![Go Reference](https://pkg.go.dev/badge/cloud.google.com/go.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:
-
-   ```bash
-   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.
-
-## Supported APIs
-
-For an updated list of all of our released APIs please see our
-[reference docs](https://cloud.google.com/go/docs/reference).
-
-## [Go Versions Supported](#supported-versions)
-
-Our libraries are compatible with at least the three most recent, major Go
-releases. They are currently compatible with:
-
-- Go 1.18
-- Go 1.17
-- Go 1.16
-- Go 1.15
-
-## 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))
-```
-
