how to get name of latest patchset and all changes of a particular Topic

[Sharath Gupta]

Hi Gerrit Experts

I am little new to Gerrit and I have started developing a plugin. I need few of the things listed below to help me write the plugin :

1. Given a change, how to get the latest patchset number.

2. Given a topic, how to get all the changes with that topic.

3. Given a patchset, how to change the aprroval to +1 or +2 or whatever.

Please let me know what I have to look into to get these. Any pointers related to this that helps are welcome.

Thanks

Sharath

Use the get change endpoint [1] with the current_revision option [2].

 

2. Given a topic, how to get all the changes with that topic.

Use the query changes endpoint [3] with the 'topic' operator [4].

 

3. Given a patchset, how to change the aprroval to +1 or +2 or whatever.

Use the review endpoint [5].

Answers above assume you're going to use the REST API.  There are also plugin APIs (for example the change API [6]).
