This release contains a couple of minor fixes, and changes to support go 1.13.

v0.16.0

Breaking changes:

• Renamed secrets/vault to secrets/hashivault.
• Renamed rdsmysql to awsmysql, rdspostgres to awspostgres, cloudmysql to gcpmysql, and cloudpostgres to gcppostgres.
• Moved the health and requestlog packages under servers.
• We made some breaking changes to be more consistent about how constructors and URLs deal with resource names, affecting:
  • secrets/azurekeyvault: Constructor changed, and URLs are now azurekeyvault://mykevaultname.vault.azure.net/keys/mykeyname/mykeyversion instead of azurekeyvault://mykeyvaultname/mykeyname/mykeyversion.
  • runtimevar/gcpruntimeconfig: Constructor changed, and URLs are now gcpruntimeconfig://projects/myproject/configs/mycfg/variables/myvar instead of gcpruntimeconfig://myproject/mycfg/myvar.
  • postgres and mysql: Removed constructors in favor of URL openers entirely.

Highlights:

• docstore: Initial version of docstore, a portable type for Document stores, with implementations for GCP Firestore, AWS DynamoDB, Azure CosmosDB (via MongoDB driver), MongoDB, and in-memory.
• blob: Improved error messages to always include the key.
• blob: Added supported for PUT and DELETE for SignedURL.
• pubsub/azuresb: Fixed a bug where acks/nacks didn't work when partitioning was enabled.
• pubsub/kafkapubsub: Fixed a bug where messages stopped being received after a repartitioning.
• pubsub/awssnssqs: Fixed handling of raw, but JSON messages.

v0.15.0

This release doesn't have functional changes. It breaks up the main module gocloud.dev to several sub-modules, which helps users have fewer dependencies when requiring only small parts of the Go CDK. The following packages have been split out to separate modules:

• pubsub/kafkapubsub
• pubsub/natspubsub
• pubsub/rabbitpubsub
• runtimevar/etcdvar
• samples
• secrets/vault

v0.14.0

Breaking changes:

• pubsub/nats: Removed the ackFunc constructor argument URL query parameter. Message.Ack is now always a no-op for NATS, Message.Nackable will return false, and Message.Nack will panic.
• pubsub/azuresb: Removed Options.AckFuncForReceiveAndDelete in favor of Options.ReceiveAndDelete; if the latter is set to true, Message.Ack will be a no-op for Azure ServiceBus, Message.Nackable will return false, and Message.Nack will panic.
• secrets/localsecrets: Now more strict about the key material it is given; it must now always be exactly 32 bytes (previously it would crop as needed). The ByteKey helper and the stringkey scheme for URLs have been removed.

Highlights:

• blob

  • Added support for a blob.Bucket that operates on a subfolder of a bucket (see blob.PrefixedBucket).
  • Added a ReaderOptions.BeforeRead hook for As.
  • gcsblob: Exposed more types via As.

• pubsub

  • Added a Message.BeforeSend hook for As.
  • Added Message.Nackable to determine if the provider supports Nack.
  • awssnssqs: Added a pubsub.Topic implementation that sends directly to an SQS queue.
  • kafkapubsub: Added new provider for Kafka.
  • rabbitpubsub: Fixed high background CPU usage.

• secrets

  • localsecrets: See breaking changes above.

• server

  • Logged traces are no longer empty.

• sql

  • Added RDS MySQL URLOpener.

v0.13.0

Breaking Changes:

• blob
  • Modified Bucket.Attributes to return *Attributes instead of Attributes.
  • gcsblob: Modified As for Reader to return *storage.Reader, not storage.Reader.
• pubsub
  • awssnssqs: Modified OpenTopic and OpenSubscription constructors to take AWS ConfigProvider instead of the raw SNS/SQS connections.
  • awssnssqs: Changed the URL scheme from awssnssqs to awssns for Topics and awssqs for Subscriptions.
  • natspubsub: Renamed CreateTopic/CreateSubscription to OpenTopic/OpenSubscription for consistency.
• secrets
  • Some provider constructors were renamed from NewKeeper to OpenKeeper for consistency.
• runtimevar
  • Some provider constructors were renamed from NewVariable to OpenVariable for consistency.
  • Decode now takes a context.Context argument.

  • The GCP Cloud SQL/Postgres Open function now return an additional function used to close the returned *sql.DB.

Highlights:

• all: Added functions to URLMux to retrieve a slice of registered schemes (e.g., blob.DefaultURLMux().BucketSchemes(), and a separate function to see if a specific scheme has been registered (e.g., blob.DefaultURLMux().ValidBucketScheme()).
• runtimevar
  • Added a new httpvar provider.
• blob
  • Added a Copy method, for copying a blob within a Bucket.
  • azureblob: Fixed bug when using SASToken.
  • fileblob: Improved List performance when using Prefix.
