JetBrains to Roll Out Kotlin/Native 0.8

Version 0.8 of Kotlin/Native brings new features and bug fixes
13 July 2018   2501

The project team of Kotlin / Native introduced the release of version 0.8. Corrections and additions have concerned the security of multithreaded programming, the expansion of library functionality and support for iOS devices. As always, alot of bugs are fixed.

Parallelism

Implemented the concept of object freezing

object Config {
  var width: Int = 10
  private set
  init {
    val file = fopen("config.txt", "r")
    if (file != null) {
              try {
              val buffer = ByteArray(2 * 1024)
                 while (true) {
                 val nextLine = fgets(buffer.refTo(0), buffer.size, file)?.toKString()
                 if (nextLine == null || nextLine.isEmpty()) break
                 val records = nextLine.split('=')
                 if (records.size != 2) continue
                 val key = records[0].trim()
                 val value = records[1].trim()
                 when (key) {
                         "width" -> width = value.toInt()
                            }
                          }
                        }
             } finally {
                fclose(file)
                    }
         }
}

This code considers the configuration file and will later receive the Config.width property. 

The Config file itself is divided for any number of threads or vorkers. After publication, the object is frozen and any attempt to change it will result in an exception (InvalidMutabilityException).

The second peculiarity of parallelism in the Kotlin / Native project is indivisible values and references. Let's add an image:

object Config {
private val icon_ = AtomicReference()
val icon: Image
get() = icon_.get()!!
fun updateIcon(file: String) {
val imageData = Image(file)
icon_.compareAndSwap(icon_.get(), imageData.freeze())
}
}

All information about the icon in the AtomicReference is frozen. Any changes are indivisible and similar information is visible to each client.

Kotlin Libraries

Starting v 0.8, the standard library (kotlin. *) is compatible with other platforms. Standard number generator and the function of mixing the collections are designed to eliminate the use of sharpened for a specific platform API. As an experiment, the project supports other libraries, for example, kotlinx.coroutines, kotlinx.serialization, and also the Ktor HTTP client.

Changes for iOS devices

Fixed issues with the publication in the App Store and the initialization of the platform. Support for the 32-bit ARM architecture of iOS processors, which allows using Kotlin / Native on older devices from Apple added.

Firefox Preview to Get Add-Ons Support

This is the new mobile browser that is based on the GeckoView engine and the Mozilla Android Components library set

Mozilla developers have added support for add-ons to the codebase of the Firefox Preview mobile browser (Fenix), which is being developed to replace the Firefox edition for the Android platform. The new browser is based on the GeckoView engine and the Mozilla Android Components library set.

The ability to connect add-ons based on the WebExtension API is available for testing in the nightly builds of Firefox Preview. The item "Add-ons Manager" appeared in the menu, which shows the add-ons available for installation. In its current form, only uBlock Origin is present in the list of add-ons compatible with Firefox Preview. Support for other add-ons is expected later.
