firestore: remove test for codes.Canceled with RPC The test is flaky and it isn't clear why. There is some nondeterminism that I can't figure out.

v0.17.0
Remove UpdateMap and UpdateStruct; rename UpdatePaths to Update. Change docref.UpdateMap(ctx, map[string]interface{}{"a.b", 1}) to docref.Update(ctx, []firestore.Update{{Path: "a.b", Value: 1}})
Change docref.UpdateStruct(ctx, []string{"Field"}, aStruct) to docref.Update(ctx, []firestore.Update{{Path: "Field", Value: aStruct.Field}})
Rename MergePaths to Merge; require args to be FieldPaths
A value stored as an integer can be read into a floating-point field, and vice versa.
Alpha status: the API is still being actively developed. As a result, it might change in backward-incompatible ways and is not recommended for production use.
Beta status: the API is largely complete, but still has outstanding features and bugs to be addressed. There may be minor backwards-incompatible changes where necessary.
Stable status: the API is mature and ready for production use. We will continue addressing bugs and feature requests.
Documentation and examples are available at https://godoc.org/cloud.google.com/go
Visit or join the google-api-go-announce group for updates on these packages.
We support the two most recent major versions of Go. If Google App Engine uses an older version, we support that as well. You can see which versions are currently supported by looking at the lines following go: in .travis.yml.
By default, each API will use Google 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.
client, err := storage.NewClient(ctx)
To authorize using a JSON key file, pass option.WithServiceAccountFile to the NewClient function of the desired package. For example:
client, err := storage.NewClient(ctx, option.WithServiceAccountFile("path/to/keyfile.json"))
You can exert more control over authorization by using the golang.org/x/oauth2 package to create an oauth2.TokenSource. Then pass option.WithTokenSource to the NewClient function: snip:# (auth-ts)
tokenSource := ...
client, err := storage.NewClient(ctx, option.WithTokenSource(tokenSource))
First create a datastore.Client to use throughout your application:
client, err := datastore.NewClient(ctx, "my-project-id")
if err != nil {
log.Fatal(err)
}
Then use that client to interact with the API:
type Post struct {
Title string
Body string `datastore:",noindex"`
PublishedAt time.Time
}
keys := []*datastore.Key{
datastore.NameKey("Post", "post1", nil),
datastore.NameKey("Post", "post2", nil),
}
posts := []*Post{
{Title: "Post 1", Body: "...", PublishedAt: time.Now()},
{Title: "Post 2", Body: "...", PublishedAt: time.Now()},
}
if _, err := client.PutMulti(ctx, keys, posts); err != nil {
log.Fatal(err)
}
First create a storage.Client to use throughout your application:
client, err := storage.NewClient(ctx)
if err != nil {
log.Fatal(err)
}
// Read the object1 from bucket. rc, err := client.Bucket("bucket").Object("object1").NewReader(ctx) if err != nil { log.Fatal(err) } defer rc.Close() body, err := ioutil.ReadAll(rc) if err != nil { log.Fatal(err) }
First create a pubsub.Client to use throughout your application:
client, err := pubsub.NewClient(ctx, "project-id")
if err != nil {
log.Fatal(err)
}
Then use the client to publish and subscribe:
// Publish "hello world" on topic1. topic := client.Topic("topic1") res := topic.Publish(ctx, &pubsub.Message{ Data: []byte("hello world"), }) // The publish happens asynchronously. // Later, you can get the result from res: ... msgID, err := res.Get(ctx) if err != nil { log.Fatal(err) } // Use a callback to receive messages via subscription1. sub := client.Subscription("subscription1") err = sub.Receive(ctx, func(ctx context.Context, m *pubsub.Message) { fmt.Println(m.Data) m.Ack() // Acknowledge that we've consumed the message. }) if err != nil { log.Println(err) }
First create a bigquery.Client to use throughout your application: snip:# (bq-1)
c, err := bigquery.NewClient(ctx, "my-project-ID") if err != nil { // TODO: Handle error. }
Then use that client to interact with the API: snip:# (bq-2)
// Construct a query. q := c.Query(` SELECT year, SUM(number) FROM [bigquery-public-data:usa_names.usa_1910_2013] WHERE name = "William" GROUP BY year ORDER BY year `) // Execute the query. it, err := q.Read(ctx) if err != nil { // TODO: Handle error. } // Iterate through the results. for { var values []bigquery.Value err := it.Next(&values) if err == iterator.Done { break } if err != nil { // TODO: Handle error. } fmt.Println(values) }
First create a logging.Client to use throughout your application: snip:# (logging-1)
ctx := context.Background() client, err := logging.NewClient(ctx, "my-project") if err != nil { // TODO: Handle error. }
Usually, you'll want to add log entries to a buffer to be periodically flushed (automatically and asynchronously) to the Stackdriver Logging service. snip:# (logging-2)
logger := client.Logger("my-log")
logger.Log(logging.Entry{Payload: "something happened!"})
Close your client before your program exits, to flush any buffered log entries. snip:# (logging-3)
err = client.Close() if err != nil { // TODO: Handle error. }
First create a spanner.Client to use throughout your application:
client, err := spanner.NewClient(ctx, "projects/P/instances/I/databases/D")
if err != nil {
log.Fatal(err)
}
// Simple Reads And Writes _, err = client.Apply(ctx, []*spanner.Mutation{ spanner.Insert("Users", []string{"name", "email"}, []interface{}{"alice", "a@example.com"})}) if err != nil { log.Fatal(err) } row, err := client.Single().ReadRow(ctx, "Users", spanner.Key{"alice"}, []string{"email"}) if err != nil { log.Fatal(err) }
