[jira] Commented: (JSIEVE-74) Script parsing fails when the string contains a backslash

["Norman Maurer (JIRA)" <se...@james.apache.org>]

    [ https://issues.apache.org/jira/browse/JSIEVE-74?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12773461#action_12773461 ] 

Norman Maurer commented on JSIEVE-74:
-------------------------------------

Just for the record, here is the rfc part which is relevant to this buf:


   A quoted string starts and ends with a single double quote (the <">
   character, ASCII 34).  A backslash ("\", ASCII 92) inside of a quoted
   string is followed by either another backslash or a double quote.
   This two-character sequence represents a single backslash or double-
   quote within the string, respectively.

> The following script fails to parse because one of the string literals contains a backslash.  The parser also reports an error in the wrong line.
> require ["fileinto", "reject", "tag", "flag"];
> # test
> if allof (header :contains "to" "\\") {
>     keep;
>     stop;
> }
> # test2
> if anyof (header :contains "subject" "foo") {
>     keep;
>     stop;
> }
> org.apache.jsieve.parser.generated.TokenMgrError: Lexical error at line 14, column 0.  Encountered: <EOF> after : "\") {\n    keep;\n    stop;\n}\n"
