appengine/datastore: Add ByteString to allow short, indexed []byte values. Change-Id: I61cb8c0c88344131faf3b973bfe8aef213f9e7a3
This repository supports the Go runtime for Managed VMs on App Engine. It provides APIs for interacting with App Engine services. Its canonical import path is google.golang.org/appengine
.
See https://developers.google.com/cloud/managed-vms for more information.
The top level directory of this repository is the appengine
package. It contains the basic types (e.g. appengine.Context
) that are used across APIs. Specific API packages are in subdirectories (e.g. datastore
).
There is an internal
subdirectory that contains service protocol buffers, plus packages required for connectivity to make API calls. App Engine apps should not directly import any package under internal
.
This section describes how to update a traditional Go App Engine app to run on Managed VMs.
The app.yaml
file (and YAML files for modules) should have these new lines added:
vm: true manual_scaling: instances: 1
See https://developers.google.com/appengine/docs/go/modules/#Go_Instance_scaling_and_class for details.
The import paths for App Engine API packages need to be made relative to google.golang.org/appengine
. You can do that manually, or by running this command to recursively update all Go source files in the current directory: (may require GNU sed)
sed -i '/"appengine/{s,"appengine,"google.golang.org/appengine,;s,appengine_,appengine/,}' \ $(find . -name '*.go')
Most App Engine services are available with exactly the same API. A few APIs were cleaned up, and some are not available yet. This list summarises the differences:
appengine.Datacenter
now takes an appengine.Context
argument.datastore.PropertyLoadSaver
has been simplified to use slices in place of channels.search.FieldLoadSaver
now handles document metadata.taskqueue.QueueStats
no longer takes a maxTasks argument. That argument has been deprecated and unused for a long time.appengine/aetest
, appengine/blobstore
, appengine/cloudsql
and appengine/runtime
have not been ported yet.appengine.BackendHostname
and appengine.BackendInstance
were for the deprecated backends feature. Use appengine.ModuleHostname
and appengine.ModuleName
instead.appengine.IsCapabilityDisabled
and appengine/capability
are obsolete.appengine/file
is deprecated. Use Google Cloud Storage instead.appengine/socket
is deprecated. Use the standard net
package instead.
