Zql [Build Status] ===. Zql is a java SQL parser, generated using JavaCC. It parses SQL constructs (no DDL) and generates a parse tree, accessible through a java API. Zql also provides basic data manipulation mechanisms, including a SQL expression evaluator, and data tuples (although Zql is definitely not a full-fledged database !). The parser code is in the zql-parser/ module, and there are some samples in zql-sample/ (you will find README files there). Zql is provided "as is", with no warranty. It is covered by the GPL v3 license. Zql is a quite old and mature project : established in 1998, with an open source version released on sourceforge in 2010 (zql.sourceforge.net), and migrated to maven + github in late 2014.

            Jira POST & PUT Rest Calls return Error 400 from Python
            Asked 2018-May-03 at 07:29

            I'm encountering a really strange issue with the Jira Rest API - whever I try to create an issue using a POST request or update one with a PUT request to jira/rest/api/latest/issue/ I receive Error code 400 from Python 2.7 requests but it succeeds from Powershell's Invoke Web Request.

            However I'm able to pull information from the Jira server using GET requests, including:

            • The list of Projects
            • The list of IssueTypes
            • The list of Custom Fields
            • The Issues of a given type for a given project
            • The Zephyr Plugin's Test Executions
            • The Zephyr Plugin's Test Cycles

            I've tried a number of troubleshooting suggestions from similar topics from the Atlassian support site already:

            • I've verified that the Authorisation is correct (it's also required for the GET requests which all work)
            • I'm testing with an account that has administrator level access to the Jira instance
            • I've stripped the json back to just the fields and format matching the REST API documentation here: jira-rest-api-examples/#creating-an-issue-examples
            • I've ensured that all the relevant session cookie and header data is stored and added to the follw-up requests
            • I've verified through Issue/createmeta that I have the capabilities to create that issue type (and as I pointed out earlier - it works in Powershell)
            • I've tried using Issuetype name and id as well as project key and id as the identifier, neither one changes anything
            • I've even tried both omitting and including the trailing slash on the /issue path in case that was important
            • I've verified that it's not a case of Python's user-agent being blocked for POST/PUT requests

            Json Body (Raw):

            Jira returns errors like "Can not instantiate value of type ..." when the request body is incorrectly formatted. In your case, you provided a string where Jira expects a more complex content (typically a dict).
