Subject [jira] [Commented] (LUCENENET-493) Make culture insensitive (like the java version)
Date Mon, 18 Jun 2012 11:26:43 GMT


Luc Vanlerberghe commented on LUCENENET-493:

Perhaps my comment was not sufficiently clear:
I didn't solve a problem in the testcases, I solved a problem in Lucene.Net itself
I happened to stumble upon the problem because I executed the tests in a non-US locale.

The java version tests if Lucene behaves independently of the culture.
Even if we can't duplicate the way this is tested, we should still make sure behaves
independently of the culture too.

When the patch is applied, as a side-effect, the tests also pass when run in another culture.

> In Java, conversion of the basic types to and from strings is locale (culture) independent.
For localized input/output one needs to use the classes in the java.text package.
> In .Net, conversion of the basic types to and from strings depends on the default Culture.
 Otherwise you have to specify CultureInfo.InvariantCulture explicitly.
> Some of the testcases in fail if they are not run on a machine with culture
set to US.
> In the current version of there are patches here and there that try to correct
for some specific cases by using string replacement (like  System.Double.Parse(s.Replace(".",
CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator)), but that seems really ugly.
> I submit a patch here that removes the old workarounds and replaces them by calls to
classes in the Lucene.Net.Support namespace that try to handle the conversions in a compatible
