# 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, use the `normalize_unicode` request option.
|
|
|
|
## 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:
|
|
```ruby
|
|
foo.to_json(skip_undefined: true)
|
|
```
|
|
to
|
|
```ruby
|
|
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](README.md) 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:
|
|
|
|
```ruby
|
|
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:
|
|
|
|
```ruby
|
|
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:
|
|
|
|
```ruby
|
|
file = client.execute(:api_method => drive.file.get, :parameters => { 'id' => 'abc123' })
|
|
```
|
|
|
|
In `0.9` the same thing can be accomplished like this:
|
|
|
|
```ruby
|
|
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](https://github.com/google/google-auth-library-ruby) 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](https://github.com/google/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:
|
|
|
|
```ruby
|
|
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:
|
|
|
|
```ruby
|
|
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:
|
|
|
|
```ruby
|
|
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:
|
|
|
|
```ruby
|
|
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:
|
|
|
|
```ruby
|
|
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:
|
|
|
|
```ruby
|
|
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.
