Migrating from version`0.10` to `0.11`

Unicode normalization

The client no longer normalizes unicode strings in path parameters. This may affect some applications using multibyte strings that were previously normalized.: To restore the previous behavior, set the following option prior to creating a service.

ClientOptions.default.normalize_unicode = true

Type change for large numbers

Previously, types declared as 64 bit numbers were mapped to strings. These are now mapped to Fixednum/Bignum.

Timeouts

Timeout options have been moved from RequestOptions to ClientOptions.

Old	New
`RequestOptions.open_timeout_sec`	`ClientOptions.open_timeout_sec`
`RequestOptions.timeout_sec`	`ClientOptions.read_timeout_sec`
`RequestOptions.timeout_sec`	`ClientOptions.send_timeout_sec`

Batch requests across services no longer supported

It is no longer possible to combine multiple services (e.g. Gail & Drive) in a batch request. If batching requests that span services, group requests for each service in their own batch request.

Migrating from version `0.9.x` to `0.10`

Only one minor breaking change was introduced in the to_json method due to a version bump for the representable gem from 2.3 to 3.0. If you used the skip_undefined in to_json, you should replace that with user_options: { skip_undefined: true }.

ex:

foo.to_json(skip_undefined: true)

foo.to_json(user_options: { skip_undefined: true })

Migrating from version `0.8.x` to `0.9` or above

Many changes and improvements have been made to the google-api-ruby-client library to bring it to 0.9. If you are starting a new project or haven't used this library before version 0.9, see the README to get started as you won't need to migrate anything.

Code written against the 0.8.x version of this library will not work with the 0.9 version without modification.

Discovery

In 0.8.x the library would "discover" APIs on the fly, introducing additional network calls and instability. That has been fixed in 0.9.

To get the drive client in 0.8.x required this:

require 'google/api_client'

client = Google::APIClient.new
drive = client.discovered_api('drive', 'v2')

In 0.9 the same thing can be accomplished like this:

require 'google/apis/drive_v2'

drive = Google::Apis::DriveV2::DriveService.new

All APIs are immediately accessible without requiring additional network calls or runtime code generation.

API Methods

The calling style for API methods has changed. In 0.8.x all calls were via a generic execute method. In 0.9 the generated services have fully defined method signatures for all available methods.

To get a file using the Google Drive API in 0.8.x required this:

file = client.execute(:api_method => drive.file.get, :parameters => { 'id' => 'abc123' })

In 0.9 the same thing can be accomplished like this:

file = drive.get_file('abc123')

Full API definitions including available methods, parameters, and data classes can be found in the generated directory.

Authorization

In the 0.9 version of this library, the authentication and authorization code was moved to the new googleauth library. While the new library provides significantly simpler APIs for some use cases, not all features have been migrated. Missing features are expected to be added by end of Q2 2015.

The underlying Signet is still used for authorization. OAuth 2 credentials obtained previously will continue to work with the 0.9 version. OAuth 1 is no longer supported.

If you were using a PKCS12 file to authorize, we recommend you generate a new key for the service account using the JSON format ( client_secret.json) file with googleauth.

Media uploads

Media uploads are significantly simpler in 0.9.

The old 0.8.x way of uploading media:

media = Google::APIClient::UploadIO.new('mymovie.m4v', 'video/mp4')
metadata = {
  'title' => 'My movie',
  'description' => 'The best home movie ever made'
}
client.execute(:api_method => drive.files.insert,
               :parameters => { 'uploadType' => 'multipart' },
               :body_object => metadata,
               :media => media )

The new way in 0.9 using upload_source and content_type parameters:

metadata = {
  title: 'My movie',
  description: 'The best home movie ever made'
}
drive.insert_file(metadata, upload_source: 'mymovie.m4v', content_type: 'video/mp4')

upload_source can be either a path to a file, an IO stream, or a StringIO instance.

Uploads are resumable and will be automatically retried if interrupted.

Media downloads

0.9 introduces support for media downloads (alt=media). To download content, use the download_dest parameter:

drive.get_file('abc123', download_dest: '/tmp/myfile.txt')

download_dest may be either a path to a file or an IO stream.

Batch Requests

The old 0.8.x way of performing batch requests:

client = Google::APIClient.new
urlshortener = client.discovered_api('urlshortener')

batch = Google::APIClient::BatchRequest.new do |result|
    puts result.data
end

batch.add(:api_method => urlshortener.url.insert,
          :body_object => { 'longUrl' => 'http://example.com/foo' })
batch.add(:api_method => urlshortener.url.insert,
          :body_object => { 'longUrl' => 'http://example.com/bar' })
client.execute(batch)

In 0.9, the equivalent code is:

require 'google/apis/urlshortener_v1'

urlshortener = Google::Apis::UrlshortenerV1::UrlshortenerService.new

urlshortener.batch do |urlshortener|
  urlshortener.insert_url({long_url: 'http://example.com/foo'}) do |res, err|
    puts res
  end
  urlshortener.insert_url({long_url: 'http://example.com/bar'}) do |res, err|
    puts res
  end
end

Or if sharing the same block:

require 'google/apis/urlshortener_v1'

urlshortener = Google::Apis::UrlshortenerV1::UrlshortenerService.new

callback = lambda { |res, err| puts res }
urlshortener.batch do |urlshortener|
  urlshortener.insert_url({long_url: 'http://example.com/foo'}, &callback)
  urlshortener.insert_url({long_url: 'http://example.com/bar'}, &callback)
end

JRuby

Jruby 1.7.4 in 2.0 compatibility mode is supported. To enable for a specific script:

jruby --2.0 myscript.rb

Or set as the default:

export JRUBY_OPTS=--2.0

JRuby 9000 will be supported once released.
