+1 - I'm currently relying on retrieving a complete social graph when
no cursor is passed. Your announcing this change right around Xmas+new
years to take effect almost immediately thereafter...

Why hasn't this been announced before? Why does the API suggest
something totally different? At the very least, can you please hold
off on deprecation of this until 2/11/2010? This is a new API change.

yes - if you do not pass in cursors, then the API will behave as
though you
requested the first cursor.
Willhelm:
Your announcement is apparently expanding the changeover from page
to
cursor in new, unannounced ways??
The API documentation page says: "If the cursor parameter is not
provided, all IDs are attempted to be returned, but large sets of
IDs
will likely fail with timeout errors."
Yesterday you wrote: "Starting soon, if you fail to pass a cursor,
the
data returned will be that of the first cursor (-1) and the
next_cursor and previous_cursor elements will be included."
I can understand the need to swap from page to cursor, but was
pleased
that a single call was still available to return (or attempt to
return) all friend/follower ids. Now you are saying that, in
addition
to the changeover from page to cursor, you are also getting rid of
this?
Can you please confirm/deny?

We noticed that some clients are still calling social graph methods
without cursor parameters. We wanted to take time to make sure that
people were calling the updated methods which return data with
cursors
instead of the old formats that do not.
As previously announced in September (http://bit.ly/46x1iL) and
November (http://bit.ly/3UQ0LU), the legacy data formats returned
as a result of calling social graph endpoints without a cursor
parameter are deprecated and will be removed.
These formats have been removed from the API wiki since September.
You should always pass a cursor parameter. Starting soon, if you
fail
to pass a cursor, the data returned will be that of the first
cursor
(-1) and the next_cursor and previous_cursor elements will be
included.
If you aren't seeing next_cursor and previous_cursor in your
results,
you are getting data back in the old format. You will need to
adjust
your parser to handle the new format.
We're going to start assuming you want data in the new format
(users_list / users / user or id_list / ids / id) instead of the
old
format (users / user or ids / id) regardless of your passing a
cursor
parameter as of 1/11/2010.
* The old formats will no longer be returned after 1/11/2010.
* Start using the new formats now by passing the 'cursor'
parameter.
To recap, the old endpoints at
/statuses/friends.xml
/statuses/followers.xml
returned
<users type="array">
<user>
<!-- ... omitted ... -->
</user>
</users>
or JSON like [{/*user record*/ /*, .../]
whereas
/statuses/friends.xml?cursor=n
/statuses/followers.xml?cursor=n
return data that looks like
<users_list>
<users type="array">
<user>
<!-- ... omitted ... -->
</user>
</users>
<next_cursor>7128872798413429387</next_cursor>
<previous_cursor>0</previous_cursor>
</users_list>
or, the JSON equivalent:
{"users":[{/*user record*/} /*, ...*/], "next_cursor":0,
"previous_cursor":0}
and the old endpoints at
/friends/ids.xml
/followers/ids.xml
returned data that looks like
<ids>
<id>1</id>
<id>2</id>
<id>3</id>
</ids>
whereas
/friends/ids.xml?cursor=n
/followers/ids.xml?cursor=n
return data that looks like
<id_list>
<ids>
<id>1</id>
<id>2</id>
<id>3</id>
</ids>
<next_cursor>1288724293877798413</next_cursor>
<previous_cursor>-1300794057949944903</previous_cursor>
</id_list>
or, the JSON equivalent:
{"ids":[1, 2, 3], "next_cursor":0, "previous_cursor":0}
