Subject [jira] [Commented] (QPID-6718) parsing errors for integer literals in selectors
Date Tue, 01 Sep 2015 14:23:47 GMT

    [ https://issues.apache.org/jira/browse/QPID-6718?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14725466#comment-14725466
] 

Gordon Sim commented on QPID-6718:
----------------------------------

Apart from stating that "numbers in the range of Java long are supported" the JMS spec mostly
defers to the Java language spec here: "Exact numeric literals use the Java integer literal
syntax." in 3.8.1.1 which is https://docs.oracle.com/javase/specs/jls/se7/html/jls-3.html#jls-3.10.1
and includes:

"A hexadecimal numeral consists of the leading ASCII characters 0x or 0X followed by one or
more ASCII hexadecimal digits interspersed with underscores, and can represent a positive,
zero, or negative integer. "

"An octal numeral consists of an ASCII digit 0 followed by one or more of the ASCII digits
0 through 7 interspersed with underscores, and can represent a positive, zero, or negative
integer. "

and

"An integer literal is of type long if it is suffixed with an ASCII letter L or l"

>             Project: Qpid
>          Issue Type: Bug
>          Components: C++ Client
>    Affects Versions: qpid-cpp-0.34
>            Reporter: Gordon Sim
>            Assignee: Andrew Stitcher
>            Priority: Minor
>
> There are a few integer literals that cause selector parsing to fail or the resulting
evaluation to be incorrect:
> (a) hexadecimal literals don't seem to be recognised, e.g. 0xFF will result in a parse
error
> (b) octal literals are evaluated as decimal e.g 077 is interpreted as decimal 77 rather
than decimal 63
> (c) large numbers fail with a lexical cast error, e.g -9223372036854775808L or 9223372036854775807L
