appengine

• Rename error classes to use the Exception suffix
  (AppEngineException, NetworkException, ProtocolException,
  ServiceException, ApplicationException) to follow Dart conventions for
  types implementing Exception. The old *Error names remain available as
  deprecated type aliases, so this change is non-breaking.
• Automated formatting and fixes.
• Cleanup legacy code.
• Fix X-Forwarded-For handling.

• Upgrade dependency package:gcloud to ^0.9.0.

• Upgrade dependency package:gcloud to ^0.9.0.

• Update dependency on googleapis_auth and http.

• Update dependency on googleapis_auth and http.

• Upgrade package:grpc to ^4.0.1.

• Upgrade package:grpc to ^4.0.1.

• Update the pubspec repository field to reflect the new repo location.

• Require package:protobuf ^3.1.0.

• Widen dependency constraint on package:http.

• Require Dart 2.19.
• Setup dbService to do retries for failed requests.

• Added topics to pubspec.yaml.

• Implement onConnectionStateChanged to sync grpc: 3.1.0

• Populate the pubspec repository field.
• Update the readme to add experimental verbiage.

• Gracefully handle cases where logging fails.

• Fix dependency on package:gcloud to version 0.8.0.

WARNING: Version 0.13.0 is broken, use 0.13.1.

• Migrated to null-safety and package:gcloud version 0.8.0.

• Setup default authClient in package:gcloud, fixing regression from introduction of Application Default Credentials in 0.12.0.

• Breaking, now using the environment variable GOOGLE_CLOUD_PROJECT instead of GCLOUD_PROJECT for project name.
• Breaking, now using Application Default Credentials instead of using the environment variable GCLOUD_KEY. This allows authentication by specifying an exported service account key in GOOGLE_APPLICATION_CREDENTIALS, or running gcloud auth application-default login on your local machine.

• Upgrade gcloud to 0.7.0 with breaking changes in datastore keys.

• Handle duplicate user-agent headers.

• Added Logging.reportError to the `logging interface, for reporting errors to Stackdriver Error Reporting when running in AppEngine.
• Report errors logged through the package:logging adapter to Logging.reportError (for reporting to Stackdriver Error Reporting).
• Updated protobuf source files.
• Reduced number of unnecessarily generated protos.

• Update Protobuf to v1.0.0
• Add client library identification header
• Fix grpc/datastore tests

• Update gRPC version dependency

• Revert 0.9.0

• Support orderingKey on pub/sub's Message type.
• Support the latest version ^15.0.0 of the googleapis package.

• Instantiate new DatastoreDB instances for each request.

• Detect dev mode when running behind a proxy.

• Add applicationContext getter to ClientContext

• Add onAcceptingConnections callback to runAppEngine()

• Update the generated protobufs.

• Update to use package:grpc version 2.0

• Refactored to use package:grpc to talk to Logging and Datastore backends.

• Added isCronJonRequest as a helper method for determining if a request originates from the AppEngine cronjob scheduler.

Breaking changes:

• Removed poorly documented assets support with broken tests.
• Removed memcache as the service was never made it past alpha.

Users of memcache should consider using Cloud Memorystore instead. This comes with a redis interface for which there are multiple packages available on pub. Serving assets is just a matter of sending a file from disk. This is easy to do without the logic that this package used to contain.

• Correct root path for serving assets.

• Support latest pkg:http and pkg:http2.

• Support for Dart 2.0 constants and updated gcloud.

• Improve output logging when memcache connections fail.
• Fix Dart 2 runtime issues.

• Delay http/2 connection dialer by 20 ms to give client enough time to receive server settings.

• Fix race condition in gRPC client between http2Connection.isOpen and http2Connection.makeRequest.

• When logging, the following protoPayload values are now populated:

  • instanceId
  • referrer
  • traceId via the X-Cloud-Trace-Context request header.

• The appengine.googleapis.com/instance_name label is also populated for all log entries.

• traceId was also added to the ClientContext class.

• When logging requests, the appengine.googleapis.com/trace_id label is populated.

• Add support for connecting to memcache instance defined by environment variables GAE_MEMCACHE_HOST and GAE_MEMCACHE_PORT.

• Add shared option to runAppEngine to enable multi-threaded operation with isolates.

Switch from Managed VMs to Flexible environment:

• Removed UsersService api.
• Removed ModulesService api.
• Removed RemoteApi api (was already deprecated).
• Introduce new GCLOUD_PROJECT and GCLOUD_KEY environment variables.
• Remove STORAGE_SERVICE_ACCOUNT_FILE environment variable.
• To prevent duplicate logging of errors, runAppEngine will no longer log request-specific errors on stdout if they got already logged via the request-specific log.

• Be less verbose in request logs printed during local development

• Fix an issue where models with un-indexed list properties could not be committed.

• Work around dev_appserver.py issue (it doesn't drain stdout we therefore avoid printing anything).

• Support gcloud package version 0.3.0.

• Require protobuf package ^0.5.0
• Support the lastest release of fixnum package.

• Added optional port argument to runAppEngine.
• Removed the call to /bin/hostname.

• Improved output of Logger.root with useLoggingPackageAdaptor.

• Pass the memcache expiration time to the memcache service. Before the expiration argument to Memcache.set and Memcache.setAll was ignored.

• Removed the expiration argument to Memcache.clear. It is not supported by the App Engine memcache API.

• Widen dependency constraint on package:logging.
