[jira] [Comment Edited] (CASSANDRA-15802) Commented-out lines that
end in a semicolon cause an error.
[ https://issues.apache.org/jira/browse/CASSANDRA-15802?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17107705#comment-17107705 ]

-------------------------------------------------------------------------
[~null-]The parser being unaware that it is currently inside a comment block does seem to be the problem. It stops parsing as soon as it encounters an end token, and sends the statement without the trailing "***/", which then naturally returns a syntax error.

> Commented-out lines that end in a semicolon cause an error.
> For example:
> /*
> describe keyspaces;
> */
>
> This produces an error:
> SyntaxException: line 2:22 no viable alternative at input '<EOF> (...*
> describe keyspaces;...)
>
> It works as expected if you use syntax:
> -- describe keyspaces;
>
> Environment:
> python:3.7.7-slim-stretch (docker image)
>
> I found that this was first seen here, and was patched, but the bug appears to have resurfaced:
