An update of the KDevelop integrated development environment has been released. Version 5.3 fully supports KDE 5 development, including with the Clang compiler. The project uses the KDE Frameworks 5 and Qt 5 libraries.

Key improvements and new features:

Improved C++ support:

A lot of work was done on stabilizing and improving our clang-based C++ language support. Notable fixes include:

  • Clang: include tooltips: fix range check. 
  • Allow overriding the path to the builtin clang compiler headers.
  • Always use the clang builtin headers for the libclang version we use.
  • Group completion requests and only handle the last one. 
  • Fix Template (Class/Function) Signatures in Clang Code Completion. 
  • Workaround: find declarations for constructor argument hints. 
  • Clang: Improve argument hint code completion. 

Improved PHP language support:

  • Much improved support for PHP Namespaces
  • Added support for Generators and Generator delegation
  • Updated and expanded the integrated documentation of PHP internals
  • Added support for PHP 7's context sensitive lexer
  • Install the parser as a library so it can be used by other projects (currently, umbrello can use it) 
  • Improved type detection of object properties
  • Added support for the object typehint
  • Better support for ClassNameReferences (instanceof)
  • Expression syntax support improvements, particularly around 'print'
  • Allow optional function parameters before non-optional ones 
  • Added support for magic constants __DIR__ and __TRAIT__

Improved Python language support

The developers have been concentrating on fixing bugs, which already have been added into the 5.2 series.

There are a couple of improved features in 5.3:

  • Inject environment profile variables into debug process environment.
  • Improve support for 'with' statements. 

Huawei May Use Russian OS Instead Android

Due to US sanctions, popular smartphone manufacturer is negotiating of using Russian OS called Aurora, which is based on Sailfish OS
11 June 2019   497

The Bell has received information from several unnamed sources about the discussion of the possibility of using the proprietary mobile operating system Aurora on some types of Huawei devices.

The movement in the direction of Aurora has so far limited itself only to a discussion of the possibility of using this OS, no plans have been presented. The discussion was attended by the Minister of Digital Development and Communications Konstantin Noskov and the Executive Director of Huawei. The meeting also raised the issue of creating a joint production of chips and software in Russia. The information was not confirmed at Rostelecom, but expressed willingness to cooperate.

Huawei declined to comment on the published information. At the same time, the company is developing its own mobile platform Hongmeng OS (Arc OS), providing compatibility with Android applications. The first release of Hongmeng OS is scheduled for the fourth quarter of this year. Two options will be offered - for China and the global smartphone market. It is alleged that Hongmeng OS has been in development since 2012 and was ready for the beginning of 2018, but was not delivered due to the use of Android as a main platform and partnership with Google.

There is evidence that for testing in China, the first batch of 1 million Hongmeng OS-based smartphones has already been distributed. Technical details are not disclosed yet and it is not clear whether the platform is built on Android code or only includes a layer for compatibility. Huawei has long been delivering its own Android edition - EMUI, it is possible that it is the basis of Hongmeng OS.

Huawei’s interest in alternative mobile systems is driven by restrictive measures introduced by the US Department of Commerce, which will restrict Huawei’s access to Android services falling under a commercial agreement with Google, as well as breaking commercial relations with ARM.

Sailfish is partly a proprietary mobile operating system with an open system environment, but closed by the user shell, basic mobile applications, QML components for building the Silica graphical interface, an interlayer for launching Android applications, a smart text input engine and a data synchronization system. The open system environment is built on the basis of Mer (fork MeeGo), which since April has been developing as an integral part of Sailfish, and packages of the Mer distribution package Nemo. On top of the Mer system components, a graphical stack is launched based on the Wayland and Qt5 library.
