#1 Updated by Sofia Papagiannaki over 10 years ago
We have to increase the length of the specific field (redirect_uri) in the Astakos database (It is really small)
and handle failures for resources exceeding this limit.
However, further consideration has to be made in order to decide which should be this limit
since this depends on the size of URI of the requested resource that theoretically is unbounded
http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.2.1
- considering only the resource URIs which currently we are willing to serve (Pithos+ resource views) and also
- taking into account the limits defined in Openstack Storage API:
http://docs.openstack.org/api/openstack-object-storage/1.0/content/ch_object-storage-dev-api-storage.html
we can get a clue about the maximum length of the requested resources, however Astakos ought to be ignorant about this.
#2 Updated by Sofia Papagiannaki over 10 years ago
In order to avoid restrictions on the redirect URI lengths we will change the database field to text.
#3 Updated by Sofia Papagiannaki over 10 years ago
After additional considerations we concluded on the following scheme:
we respective column type will be text but the api will restrict it to a configurable value (default 5000 chars).
