------------------------------------------
Summary: Make lucene.net culture insensitive (like the java
version)
Key: LUCENENET-493
URL: https://issues.apache.org/jira/browse/LUCENENET-493
Project: Lucene.Net
Issue Type: Bug
Components: Lucene.Net Core, Lucene.Net Test
Affects Versions: Lucene.Net 3.0.3
Reporter: Luc Vanlerberghe
Fix For: Lucene.Net 3.0.3
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 lucene.net fail if they are not run on a machine with
culture set to US.
In the current version of lucene.net 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 way.
