Support retrieving available revisions of a document

[adam8797]

I would like to be able to request a Document from CouchDB and optionally include the revs_info=true parameter to retrieve which revisions are available in the database.

There are numerous ways that this could be implemented:

• Included with FindOptions and used in FindAsync()
• A separate function Task<List<string>> GetAvailableRevisions(string) and/or Task<List<Revision>> GetRevisionInfo(string)
• Include revs_info as a property on CouchDocument

Hi, sorry the late answer, I can add it to FindOptions I think it's the best place

Thanks! Looking forward to integrating your changes.

@adam8797 can you check if the dev branch works for you?

[matteobortolazzo]

nvm there are strange compilation errors

[adam8797]

No worries, I just got it cloned when I saw this come in. Lmk when you would like me to test!

Ok now it should be good

Looks like your CouchDB.Driver.Types.Revisions.Start property should be a number type, not a string:

public class Revisions
{
    [DataMember, JsonProperty("start")] public int Start { get; internal set; }

    [JsonIgnore] public IReadOnlyCollection<string> IDs { get; private set; }
    [DataMember, JsonProperty("ids")] private List<string> IdsOther { set { IDs = value?.AsReadOnly(); } }
}

but other than that, this looks good to me!

I got this from the DB

    "_revisions": {
        "start": 2,
        "ids": [
            "1967b37a2500d2e227b987769d93d01d",
            "f56ef9fa04215b2174e13d156e0f1219"
        ]
    }

Sorry now I get it... I copy pasted... Fixed. I think I can release, I tested it too
