Test with local de-CH is failing

stephen's Avatar

I have a build running on appveyor which fails constantly when doing tests with locale de-CH. On my local system (de-DE the test runs fine).
I've enhanced the exception output and I receive a weird response for decimal formats:

System.FormatException : Huh: Formatting '1.0' with de-CH failed (delimiter: ',', separator: '�')\r\n---- System.FormatException : Input string was not in a correct format.

The input string is 1.0 which is valid for de-CH.

Is there any limitation on localizations within the build server environment?

Best regards

    This won't help. I'm doing tests in the source code with different locales. It this problem related to specific locales?

            public void DecimalDeCh()
                CultureInfo info = new CultureInfo("de-CH");
                Assert.Equal("de-CH", info.Name);
                info.TextInfo.ListSeparator = ";";

                string data = "Test1;Test3;\"Test\";\nData1;Data2;1.0\nData1;Data2;2.0\nData1;Data2\nData1;Data2;2.43\n";
                CsvStreamImporter streamImporter = new CsvStreamImporter(GenerateStreamFromString(data), info);
                streamImporter.SetDataType("Test", typeof(DecimalColumnDefinition));
                Assert.Equal(1M, streamImporter.GetValue(2));
                Assert.Equal(2M, streamImporter.GetValue(2));
                Assert.Equal(0M, streamImporter.GetValue(2));
                Assert.Equal(2.43M, streamImporter.GetValue(2));

    The internal routine is doing the following conversion:

                    return System.Convert.ToDecimal(value, cultureInfo);
                catch (FormatException fe)
                    throw new FormatException(string.Format("Huh: Formatting {0} with {1} failed (delimiter: '{2}', separator: '{3}'", value, cultureInfo.Name, cultureInfo.NumberFormat.NumberDecimalSeparator, cultureInfo.NumberFormat.NumberGroupSeparator), fe);

    At least for de-DE it's working fine. If added the following workaround for de-CH to get things running:

                info.NumberFormat.NumberDecimalSeparator = ".";
                info.NumberFormat.NumberGroupSeparator = "'";

    Anyhow I would like to see this fixed if possible.

    Indeed, the problem exists. This fails on AppVeyor but works locally.

    Will take a look into that.

    OK, this issue has been fixed on all servers.
