# Go App Engine packages
[![Build Status](https://travis-ci.org/golang/appengine.svg)](https://travis-ci.org/golang/appengine)
This repository supports the Go runtime on *App Engine standard*.
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 [GitHub's issue
tracker](https://github.com/golang/appengine/issues).
## Upgrading an App Engine app to the flexible environment
This package does not work on *App Engine flexible*.
There are many differences between the App Engine standard environment and
the flexible environment.
See the [documentation on upgrading to the flexible environment](https://cloud.google.com/appengine/docs/flexible/go/upgrading).
## Directory structure
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`.
## Updating from legacy (`import "appengine"`) packages
If you're currently using the bare `appengine` packages
(that is, not these ones, imported via `google.golang.org/appengine`),
then you can use the `aefix` tool to help automate an upgrade to these packages.
Run `go get google.golang.org/appengine/cmd/aefix` to install it.
### 1. Update import paths
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`.
### 2. Update code using deprecated, removed or modified APIs
Most App Engine services are available with exactly the same API.
A few APIs were cleaned up, and there are some differences:
* `appengine.Context` has been replaced with the `Context` type from `golang.org/x/net/context`.
* Logging methods that were on `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.
* Most of `appengine/file` and parts of `appengine/blobstore` are deprecated.
Use [Google Cloud Storage](https://godoc.org/cloud.google.com/go/storage) if the
feature you require is not present in the new
[blobstore package](https://google.golang.org/appengine/blobstore).
* `appengine/socket` is not required on App Engine flexible environment / Managed VMs.
Use the standard `net` package instead.
