Get patch information from Gerrit using SSH

Use the command line (SSH) to query the Gerrit, official address: https://review.openstack.org/Documentation/cmd-query.html

Program examples

Import OS, JSON def Get_patch_info (Gerrit_home, patch_id):    cmd_str='ssh%s GERRIT query--format=json-- Comments change:%d'%(gerrit_home, patch_id)    = os.popen (cmd_str)    #  See note     process.close ()    = json.loads (output) # return is dict      return Jsn_data

Description: The query result will always return more than one row of query statistics on the last line, even if the query result is empty:
{"Morechanges": false, "runtimemilliseconds":, "RowCount": 1, "type": "Stats"}

If you use the shell, you can use JQ for parsing. JQ is able to format and select JSON results.

Install sudo apt-get install JQ

JSON-related I briefly introduced here, I hope to further understand the JQ and use can go to http://stedolan.github.io/jq/manual/, hope to understand the source of implementation, you can go to https://github.com/ STEDOLAN/JQ, it is expected that the author used flex and bison to parse json.

Our sample JSON comes from the first article in the reference document.

With Google search, there is an article in Kernalpanic about Jshon and json.sh provide additional ideas.
