Dear All,
I do encounter a very strange Issue.
I have been adding a test to `swift-corelibs-foundation/testJSONSerialization.swift`
This test succeed within swift-corelibs-foundation test, but fails when repackaged to a Cocoa CLI app.
The swift-corelibs-foundation test :
func test_serializeFloatingPointWithANonDotDecimalSeparatorLocale() {
// We use a locale that is using "," as decimal separator.
setlocale(LC_ALL,"fr_FR")
let dictionary = ["decimalValue":1.1]
do{
let data = try JSONSerialization.data(withJSONObject: dictionary)
if let json = String(data:data, encoding:.utf8){
XCTAssert(!json.contains(","), "Expected result: \"{\"decimalValue\":1.1000000000000001}\" found: \"\(json)\"" )
}else{
XCTFail("Failed during string encoding")
}
}catch{
XCTFail("Failed during serialization")
}
}
The simple CLI code that proves the bug (https://bugs.swift.org/browse/SR-6631\)
//
// main.swift
// doubleEncoding

import Foundation
// Let's set to french
setlocale(LC_ALL,"fr_FR")
do{
let dictionary = ["decimalValue":1.1]
let data = try JSONSerialization.data(withJSONObject: dictionary)
if let json = String(data:data, encoding:.utf8){
// the result is : "{"decimalValue":1,1000000000000001}"
// The decimal separator should not be "," but "."
print(json)
}
}catch{
print("\(error)")
}
Any idea ?
I do use Toolchain: Swift Development Snapshot 2017-12-17 (a)
