http://bugs.exim.org/show_bug.cgi?id=749 Summary: Regression: whitespace should compare numerically equal to zero Product: Exim Version: 4.69 Platform: Other OS/Version: All Status: NEW Keywords: work:tiny Severity: bug Priority: medium Component: String expansion AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] CC: [email protected] George R. Kasica in June 2008 experienced problems upgrading from Exim 4.63 to Exim 4.69 because the fixes to guard against numerical overflow no longer compared a string consisting only of whitespace as numerically equal to zero. Fixes for overflow added in 4.64; in 4.66 ChangeLog entry PH/01 is: (i) An empty string was always treated as zero by the numeric comparison operators. This behaviour has been restored. The reporter's problem was a MySQL query returning a single space character in a column normally containing numbers. 4.63 is still used, with patches, by some OS vendors. The next release should probably fix this regression, even though the current behaviour is clean and correct, to make life less stressful for OS packagers and their own bug-handling systems. -- Configure bugmail: http://bugs.exim.org/userprefs.cgi?tab=email -- ## List details at http://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
