nova flavor-list only shows 1000 flavors

[LaMont Jones]

After I created a thousand new flavors (to enable some automation), with IDs 1000-1999, nova flavor-list now displays flavor 1, followed by 1000-1998, and then stops.

Flavors 1999 and 2-6 are still valid and usable, just absent from the output of flavor-list (flavor-show is happy to provide details).

(Also, performance seems to have been hurt by the number of flavors. Does it read all the data over the network before printing any of it??)

The nova version in question is folsom.

I reproduct the bug.
firstly, close api_rate_limit.

use the command below to create 2000 flavor.
$ for i in {1..2000}; do nova flavor-create f-$i $i 1024 20 1 ;done;

then I use novaclient to list all flavor
$ time nova flavor-list

I found there is a configuration item named 'osapi_max_limit=1000', which set the default maximum number of items to return to 1000. So the number of flavor only up to 1000.

We can hit the REST API like this to get more items.
/flavors?limit=2000

But novaclient default get each flavor's extra_spec is annoying me.

    Make list flavor show extra specs optional.

    Flavor list will get each flavors extra_specs by making fresh requests to nova.
    When there are lots of flavors, the flavor list will take a while to run. So
    let us make show extra-specs optional.

    Fix bug: #1166455
