cmd/aedeploy: ignore go1.7 build tag The go1.7 runtime isn't out yet, but aedeploy built with a local Go 1.7 will bundle dependencies suited for a 1.7 builder. Ignore the go1.7 build tag to keep bundling dependencies like an aedeploy built with 1.6. Change-Id: I9463562ba5b6e8cbae2bf6cfcb405c9987bf27a7
This repository supports the Go runtime on App Engine, including both the standard App Engine and the “App Engine flexible environment” (formerly known as “Managed VMs”). It provides APIs for interacting with App Engine services. Its canonical import path is google.golang.org/appengine
.
See https://cloud.google.com/appengine/docs/go/ for more information.
File issue reports and feature requests on the Google App Engine issue tracker.
The top level directory of this repository is the appengine
package. It contains the basic APIs (e.g. appengine.NewContext
) that apply 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 an older Go App Engine app to use these packages. A provided tool, aefix
, can help automate steps 2 and 3 (run go get google.golang.org/appengine/cmd/aefix
to install it), but read the details below since aefix
can't perform all the changes.
The app.yaml
file (and YAML files for modules) should have these new lines added:
vm: true
See https://cloud.google.com/appengine/docs/go/modules/#Go_Instance_scaling_and_class for details.
The import paths for App Engine packages are now fully qualified, based at google.golang.org/appengine
. You will need to update your code to use import paths starting with that; for instance, code importing appengine/datastore
will now need to import google.golang.org/appengine/datastore
.
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.Context
has been replaced with the Context
type from golang.org/x/net/context
.appengine.Context
are now functions in google.golang.org/appengine/log
.appengine.Timeout
has been removed. Use context.WithTimeout
instead.appengine.Datacenter
now takes a context.Context
argument.datastore.PropertyLoadSaver
has been simplified to use slices in place of channels.delay.Call
now returns an error.search.FieldLoadSaver
now handles document metadata.urlfetch.Transport
no longer has a Deadline field; set a deadline on the context.Context
instead.aetest
no longer declares its own Context type, and uses the standard one instead.taskqueue.QueueStats
no longer takes a maxTasks argument. That argument has been deprecated and unused for a long time.appengine.BackendHostname
and appengine.BackendInstance
were for the deprecated backends feature. Use appengine.ModuleHostname
and appengine.ModuleName
instead.appengine/file
and parts of appengine/blobstore
are deprecated. Use Google Cloud Storage instead.appengine/socket
is not required on App Engine flexible environment / Managed VMs. Use the standard net
package instead.
