'postid' field in metaWeblog.getRecentPosts should be a string

[mrroundhill]

In 3.1, the xml-rpc metaWeblog.getRecentPosts call is returning the 'postid' field as an integer when it should be a string:

Clients such as the WordPress for iPhone app can't handle the different type and force closes when refreshing the posts tab.

(In [16508]) Ensure that we return post IDs as strings to honour API defintions. See #15517

We need to check the other API definitions to ensure we return the correct datatypes.

I'd recommend being very cautious about this types of changes, for things that have been one way for a very long time. This might be the right thing to do, but that doesn't rule out the potential for causing problems with a large number of existing clients.

blog_id needs to be a string too.

We haven't seen any more reports of broken apis since the last change which was committed in [16572]

Closing as fixed - open a new ticket for any newly discovered issues.

I think a mistake was made here. The Blogger API actually says that the post ID should return a long, not a string. Also, getPost should also have been changed but is not. See ticket #20548.
