Tyler Hobbs commented on CASSANDRA-7111: ---------------------------------------- I should have noticed these in the first review, but a couple of additional changes: * Since ErrorCollector is the only implementation of ErrorListener, I would prefer to just leave out the ErrorListener interface (unless you have plans to use it soon) * For mock test classes like MockToken, you can leave out things like {{/\*\* \{\@inheritDoc\} \*/}} javadocs There's also still a bit of trailing whitespace in ErrorCollector and Cql.g in the patch, and the unit tests need to be updated for the whitespace change. > Include snippet of CQL query near error in SyntaxError messages > --------------------------------------------------------------- > > Key: CASSANDRA-7111 > URL: https://issues.apache.org/jira/browse/CASSANDRA-7111 > Project: Cassandra > Issue Type: Improvement > Components: API, Tools > Reporter: Tyler Hobbs > Assignee: Benjamin Lerer > Labels: cql > Fix For: 2.1.1 > > Attachments: CASSANDRA-7111-V2.txt, CASSANDRA-7111.txt > > > When a SyntaxError is returned, including a snippet of the query close to the > error would make a lot of error messages easier to understand. For example, > if you did this with the python driver: > {code} > session.execute(SELECT * FROM users WHERE username='%s', ['Joe Smith']) > {code} > you would wind up with an extra set of single quotes (the driver > automatically escapes and quotes input). If a snippet like {{...WHERE > username=''Joe Smith''}} were included in the error message, this would be > pretty easy to spot. -- This message was sent by Atlassian JIRA (v6.2#6252)
