# 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,
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](https://code.google.com/p/googleappengine/issues/entry?template=Go%20defect).
## 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 a Go App Engine app
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.
### 1. Update YAML files (App Engine flexible environment / Managed VMs only)
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.
### 2. 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`.
### 3. 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 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`.
* 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.

}
The environment variable APPENGINE_DEV_APPSERVER specifies the location of the
dev_appserver.py executable to use. If unset, the system PATH is consulted.

Package cloudsql exposes access to Google Cloud SQL databases.
This package does not work in App Engine "flexible environment".
This package is intended for MySQL drivers to make App Engine-specific
connections. Applications should use this package through database/sql:
Select a pure Go MySQL driver that supports this package, and use sql.Open
with protocol "cloudsql" and an address of the Cloud SQL instance.
A Go MySQL driver that has been tested to work well with Cloud SQL
is the go-sql-driver:
import "database/sql"
import _ "github.com/go-sql-driver/mysql"
db, err := sql.Open("mysql", "user@cloudsql(project-id:instance-name)/dbname")
Another driver that works well with Cloud SQL is the mymysql driver:
import "database/sql"
import _ "github.com/ziutek/mymysql/godrv"
db, err := sql.Open("mymysql", "cloudsql:instance-name*dbname/user/password")
Using either of these drivers, you can perform a standard SQL query.
This example assumes there is a table named 'users' with
columns 'first_name' and 'last_name':
rows, err := db.Query("SELECT first_name, last_name FROM users")
if err != nil {
log.Errorf(ctx, "db.Query: %v", err)
}
defer rows.Close()
for rows.Next() {
var firstName string
var lastName string
if err := rows.Scan(&firstName, &lastName); err != nil {
log.Errorf(ctx, "rows.Scan: %v", err)
continue
}
log.Infof(ctx, "First: %v - Last: %v", firstName, lastName)
}
if err := rows.Err(); err != nil {
log.Errorf(ctx, "Row error: %v", err)
}

Package datastore provides a client for App Engine's datastore service.
Basic Operations
Entities are the unit of storage and are associated with a key. A key
consists of an optional parent key, a string application ID, a string kind
(also known as an entity type), and either a StringID or an IntID. A
StringID is also known as an entity name or key name.
It is valid to create a key with a zero StringID and a zero IntID; this is
called an incomplete key, and does not refer to any saved entity. Putting an
entity into the datastore under an incomplete key will cause a unique key
to be generated for that entity, with a non-zero IntID.
An entity's contents are a mapping from case-sensitive field names to values.
Valid value types are:
- signed integers (int, int8, int16, int32 and int64),
- bool,
- string,
- float32 and float64,
- []byte (up to 1 megabyte in length),
- any type whose underlying type is one of the above predeclared types,
- ByteString,
- *Key,
- time.Time (stored with microsecond precision),
- appengine.BlobKey,
- appengine.GeoPoint,
- structs whose fields are all valid value types,
- slices of any of the above.
Slices of structs are valid, as are structs that contain slices. However, if
one struct contains another, then at most one of those can be repeated. This
disqualifies recursively defined struct types: any struct T that (directly or
indirectly) contains a []T.
The Get and Put functions load and save an entity's contents. An entity's
contents are typically represented by a struct pointer.
Example code:
type Entity struct {
Value string
}
func handle(w http.ResponseWriter, r *http.Request) {
ctx := appengine.NewContext(r)
k := datastore.NewKey(ctx, "Entity", "stringID", 0, nil)
e := new(Entity)
if err := datastore.Get(ctx, k, e); err != nil {
http.Error(w, err.Error(), 500)
return
}
old := e.Value
e.Value = r.URL.Path
if _, err := datastore.Put(ctx, k, e); err != nil {
http.Error(w, err.Error(), 500)
return
}
w.Header().Set("Content-Type", "text/plain; charset=utf-8")
fmt.Fprintf(w, "old=%q\nnew=%q\n", old, e.Value)
}
GetMulti, PutMulti and DeleteMulti are batch versions of the Get, Put and
Delete functions. They take a []*Key instead of a *Key, and may return an
appengine.MultiError when encountering partial failure.
Properties
An entity's contents can be represented by a variety of types. These are
typically struct pointers, but can also be any type that implements the
PropertyLoadSaver interface. If using a struct pointer, you do not have to
explicitly implement the PropertyLoadSaver interface; the datastore will
automatically convert via reflection. If a struct pointer does implement that
interface then those methods will be used in preference to the default
behavior for struct pointers. Struct pointers are more strongly typed and are
easier to use; PropertyLoadSavers are more flexible.
The actual types passed do not have to match between Get and Put calls or even
across different App Engine requests. It is valid to put a *PropertyList and
get that same entity as a *myStruct, or put a *myStruct0 and get a *myStruct1.
Conceptually, any entity is saved as a sequence of properties, and is loaded
into the destination value on a property-by-property basis. When loading into
a struct pointer, an entity that cannot be completely represented (such as a
missing field) will result in an ErrFieldMismatch error but it is up to the
caller whether this error is fatal, recoverable or ignorable.
By default, for struct pointers, all properties are potentially indexed, and
the property name is the same as the field name (and hence must start with an
upper case letter). Fields may have a `datastore:"name,options"` tag. The tag
name is the property name, which must be one or more valid Go identifiers
joined by ".", but may start with a lower case letter. An empty tag name means
to just use the field name. A "-" tag name means that the datastore will
ignore that field. If options is "noindex" then the field will not be indexed.
If the options is "" then the comma may be omitted. There are no other
recognized options.
Fields (except for []byte) are indexed by default. Strings longer than 1500
bytes cannot be indexed; fields used to store long strings should be
tagged with "noindex". Similarly, ByteStrings longer than 1500 bytes cannot be
indexed.
Example code:
// A and B are renamed to a and b.
// A, C and J are not indexed.
// D's tag is equivalent to having no tag at all (E).
// I is ignored entirely by the datastore.
// J has tag information for both the datastore and json packages.
type TaggedStruct struct {
A int `datastore:"a,noindex"`
B int `datastore:"b"`
C int `datastore:",noindex"`
D int `datastore:""`
E int
I int `datastore:"-"`
J int `datastore:",noindex" json:"j"`
}
Structured Properties
If the struct pointed to contains other structs, then the nested or embedded
structs are flattened. For example, given these definitions:
type Inner1 struct {
W int32
X string
}
type Inner2 struct {
Y float64
}
type Inner3 struct {
Z bool
}
type Outer struct {
A int16
I []Inner1
J Inner2
Inner3
}
then an Outer's properties would be equivalent to those of:
type OuterEquivalent struct {
A int16
IDotW []int32 `datastore:"I.W"`
IDotX []string `datastore:"I.X"`
JDotY float64 `datastore:"J.Y"`
Z bool
}
If Outer's embedded Inner3 field was tagged as `datastore:"Foo"` then the
equivalent field would instead be: FooDotZ bool `datastore:"Foo.Z"`.
If an outer struct is tagged "noindex" then all of its implicit flattened
fields are effectively "noindex".
The PropertyLoadSaver Interface
An entity's contents can also be represented by any type that implements the
PropertyLoadSaver interface. This type may be a struct pointer, but it does
not have to be. The datastore package will call Load when getting the entity's
contents, and Save when putting the entity's contents.
Possible uses include deriving non-stored fields, verifying fields, or indexing
a field only if its value is positive.
Example code:
type CustomPropsExample struct {
I, J int
// Sum is not stored, but should always be equal to I + J.
Sum int `datastore:"-"`
}
func (x *CustomPropsExample) Load(ps []datastore.Property) error {
// Load I and J as usual.
if err := datastore.LoadStruct(x, ps); err != nil {
return err
}
// Derive the Sum field.
x.Sum = x.I + x.J
return nil
}
func (x *CustomPropsExample) Save() ([]datastore.Property, error) {
// Validate the Sum field.
if x.Sum != x.I + x.J {
return errors.New("CustomPropsExample has inconsistent sum")
}
// Save I and J as usual. The code below is equivalent to calling
// "return datastore.SaveStruct(x)", but is done manually for
// demonstration purposes.
return []datastore.Property{
{
Name: "I",
Value: int64(x.I),
},
{
Name: "J",
Value: int64(x.J),
},
}
}
The *PropertyList type implements PropertyLoadSaver, and can therefore hold an
arbitrary entity's contents.
Queries
Queries retrieve entities based on their properties or key's ancestry. Running
a query yields an iterator of results: either keys or (key, entity) pairs.
Queries are re-usable and it is safe to call Query.Run from concurrent
goroutines. Iterators are not safe for concurrent use.
Queries are immutable, and are either created by calling NewQuery, or derived
from an existing query by calling a method like Filter or Order that returns a
new query value. A query is typically constructed by calling NewQuery followed
by a chain of zero or more such methods. These methods are:
- Ancestor and Filter constrain the entities returned by running a query.
- Order affects the order in which they are returned.
- Project constrains the fields returned.
- Distinct de-duplicates projected entities.
- KeysOnly makes the iterator return only keys, not (key, entity) pairs.
- Start, End, Offset and Limit define which sub-sequence of matching entities
to return. Start and End take cursors, Offset and Limit take integers. Start
and Offset affect the first result, End and Limit affect the last result.
If both Start and Offset are set, then the offset is relative to Start.
If both End and Limit are set, then the earliest constraint wins. Limit is
relative to Start+Offset, not relative to End. As a special case, a
negative limit means unlimited.
Example code:
type Widget struct {
Description string
Price int
}
func handle(w http.ResponseWriter, r *http.Request) {
ctx := appengine.NewContext(r)
q := datastore.NewQuery("Widget").
Filter("Price <", 1000).
Order("-Price")
b := new(bytes.Buffer)
for t := q.Run(ctx); ; {
var x Widget
key, err := t.Next(&x)
if err == datastore.Done {
break
}
if err != nil {
serveError(ctx, w, err)
return
}
fmt.Fprintf(b, "Key=%v\nWidget=%#v\n\n", key, x)
}
w.Header().Set("Content-Type", "text/plain; charset=utf-8")
io.Copy(w, b)
}
Transactions
RunInTransaction runs a function in a transaction.
Example code:
type Counter struct {
Count int
}
func inc(ctx context.Context, key *datastore.Key) (int, error) {
var x Counter
if err := datastore.Get(ctx, key, &x); err != nil && err != datastore.ErrNoSuchEntity {
return 0, err
}
x.Count++
if _, err := datastore.Put(ctx, key, &x); err != nil {
return 0, err
}
return x.Count, nil
}
func handle(w http.ResponseWriter, r *http.Request) {
ctx := appengine.NewContext(r)
var count int
err := datastore.RunInTransaction(ctx, func(ctx context.Context) error {
var err1 error
count, err1 = inc(ctx, datastore.NewKey(ctx, "Counter", "singleton", 0, nil))
return err1
}, nil)
if err != nil {
serveError(ctx, w, err)
return
}
w.Header().Set("Content-Type", "text/plain; charset=utf-8")
fmt.Fprintf(w, "Count=%d", count)
}
Metadata
The datastore package provides access to some of App Engine's datastore
metadata. This metadata includes information about the entity groups,
namespaces, entity kinds, and properties in the datastore, as well as the
property representations for each property.
Example code:
func handle(w http.ResponseWriter, r *http.Request) {
// Print all the kinds in the datastore, with all the indexed
// properties (and their representations) for each.
ctx := appengine.NewContext(r)
kinds, err := datastore.Kinds(ctx)
if err != nil {
serveError(ctx, w, err)
return
}
w.Header().Set("Content-Type", "text/plain; charset=utf-8")
for _, kind := range kinds {
fmt.Fprintf(w, "%s:\n", kind)
props, err := datastore.KindProperties(ctx, kind)
if err != nil {
fmt.Fprintln(w, "\t(unable to retrieve properties)")
continue
}
for p, rep := range props {
fmt.Fprintf(w, "\t-%s (%s)\n", p, strings.Join(", ", rep))
}
}
}

/*
Package delay provides a way to execute code outside the scope of a
user request by using the taskqueue API.
To declare a function that may be executed later, call Func
in a top-level assignment context, passing it an arbitrary string key
and a function whose first argument is of type context.Context.
var laterFunc = delay.Func("key", myFunc)
It is also possible to use a function literal.
var laterFunc = delay.Func("key", func(c context.Context, x string) {
// ...
})
To call a function, invoke its Call method.
laterFunc.Call(c, "something")
A function may be called any number of times. If the function has any
return arguments, and the last one is of type error, the function may
return a non-nil error to signal that the function should be retried.
The arguments to functions may be of any type that is encodable by the gob
package. If an argument is of interface type, it is the client's responsibility
to register with the gob package whatever concrete type may be passed for that
argument; see http://golang.org/pkg/gob/#Register for details.
Any errors during initialization or execution of a function will be
logged to the application logs. Error logs that occur during initialization will
be associated with the request that invoked the Call method.
The state of a function invocation that has not yet successfully
executed is preserved by combining the file name in which it is declared
with the string key that was passed to the Func function. Updating an app
with pending function invocations is safe as long as the relevant
functions have the (filename, key) combination preserved.
The delay package uses the Task Queue API to create tasks that call the
reserved application path "/_ah/queue/go/delay".
This path must not be marked as "login: required" in app.yaml;
it must be marked as "login: admin" or have no access restriction.
