http://issues.apache.org/bugzilla/show_bug.cgi?id=40992 Summary: ENV property of EXEC task must support case insensitive variable names on Windows, either by default or via an extra attribute Product: Ant Version: 1.6.5 Platform: PC OS/Version: Windows Server 2003 Status: NEW Severity: major Priority: P2 Component: Core tasks AssignedTo: dev@ant.apache.org ReportedBy: [EMAIL PROTECTED] Environment variables are case insensitive on Windows, but ANT ignores that fact. If an environment variable is already defined on the system, ENV property of the EXEC tag fails to modify it, if name case does not match. For example, nls_lang variable is defined at the system level as american_america.we8mswin1252. To perform correct export of data from Oracle, it needs to be set to american_america.al32utf8. <exec executable="exp.exe" failonerror="true"> <env key="NLS_LANG" value="american_america.al32utf8"/> <arg line="scott/tiger file=scott-exp.dmp"/> </exec> The above task would fail to change the NLS_LANG variable (because nls_lang variable is already defined) and exported data won't be valid (loss of localized data and questionable statistics). If ENV parameter is specified as <env key="nls_lang" value="american_america.al32utf8"/> the variable in question will be properly matched and overwritten. Unfortunately, there are 128 (2^7) possible ways how the "NLS_LANG" variable can be defined on Windows and it's not realistic to "use the right case". While running on Windows, ANT should defaults to the Windows behavior, or al least provide an extra attribute (something like casesensitivity= {"true"|false"}) to allow case insensitive environment variable match. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
