The developers of the LineageOS project, which replaced CyanogenMod after abandoning the project of Cyanogen Inc, published a report on the development of the LineageOS 16 branch based on the Android 9 platform. Since March, the number of assemblies provided by the project has increased to 36 devices. Recent changes are noted:

  • AOSP’s Night Display now controls night mode (on recent devices only, such as those with a Snapgragon 820 or more recent)
  • LiveDisplay remains available for all its other features
  • The volume panel can now be expanded to control all the various volume streams
  • The volume panel can now be optionally relocated to the left
  • Expanded quick settings are back
  • Detailed views for the following tiles are available: Wi-Fi, Bluetooth, Mobile Data, Location, Profiles
  • New default wallpaper and a new wallpapers app with many new, and old, wallpapers
  • Other than the usual nature, urban and abstract themed wallpapers, monochromatic and gradients wallpapers are now available
  • Privacy Guard now supports apps in the Work Profile
  • It’s possible to add up to two LockScreen shortcuts again
  • Circle battery is back after being missing since LineageOS 13.0
  • Notification ringtone level can be unlinked from phone calls ringtone level
  • GPS battery saving mode can now be enabled from the Settings
  • Vim has been updated to version 8.1
  • Nano has been updated to version 4.2
  • Fixed issue were using certain private DNS caused devices to crash thanks to backported fix from Q
  • Support for bluetooth SBC DualChannel HD has been added (both 15.1 and 16.0)
  • Performance improvements for Eleven (music player app) (both 15.1 and 16.0)
  • Updated call recording configurations (both 15.1 and 16.0)

Additionally, developers mark the termination of the formation of assemblies LineageOS 15.1 for Google Nexus 4, Asus Zenfone Max Pro M1, Nvidia Shield Tablet, Samsung Galaxy S9, Samsung Galaxy S9 + and ZTE Axon 7.

LizardFS 3.13.0-rc2 to be Rolled Out

The release of LizardFS 3.13.0 with  Raft consensus algorithm as a main innovation is scheduled to be released in late December

After a year-long pause in development, work on the new branch of the fault-tolerant distributed file system LizardFS 3.13 was resumed and the second candidate for releases was published. Recently there was a change of ownership of the company developing LizardFS, a new leadership was adopted and the developers changed. Over the past two years, the project has moved away from the community and did not pay due attention to it, but the new team intends to revive its previous relations with the community and establish close interaction with it. The project code is written in C and C ++ and is distributed under the GPLv3 license.

LizardFS is a distributed cluster file system that allows you to disperse data across different servers, but provide access to them in the form of a single large partition, the work with which is carried out by analogy with traditional disk partitions. The mounted section with LizardFS supports POSIX file attributes, ACLs, locks, sockets, channels, device files, symbolic and hard links. The system does not have a single point of failure, all components are redundant. Parallelization of data operations is supported (several clients can access files at the same time).

The release of LizardFS 3.13.0 is scheduled to be released in late December. The main innovation of LizardFS 3.13 is the use of the Raft consensus algorithm (using its own implementation of uRaft, which was previously used in commercial products) to ensure fault tolerance (switching master servers in the event of a failure). Using uRaft simplifies setup and reduces latency when recovering from a failure, but requires at least three working nodes, one of which is used for quorum.

Among other changes: a new client based on the FUSE3 subsystem, solving problems with error correction, the nfs-ganesha plugin was rewritten in C language. The 3.13.0-rc2 update fixes several critical errors that made the previous test releases of the 3.13 branch unsuitable for use (patches for the 3.12 branch have not yet been published, and the upgrade from 3.12 to 3.13 still leads to complete data loss).

In 2020, work will focus on developing Agama, the new completely rewritten core of LizardFS, which, according to the developers, will provide a three-fold increase in productivity compared to branch 3.12. Agama will make the transition to event-driven architecture (event driven), asio-based I / O based on asio, work primarily in user space (to reduce the dependence on kernel caching mechanisms). In addition, a new debugging subsystem and network activity analyzer with support for performance tuning will be offered.

Full support for versioning write operations will be added to the LizardFS client, which will increase the reliability of disaster recovery, solve the problems that arise when different clients share the same data, and will achieve a significant increase in performance. The client will be transferred to its own network subsystem operating in user space. The first working prototype of LizardFS based on Agama is planned to be prepared in the second quarter of 2020. At the same time, they promise to implement tools for integrating LizardFS with the Kubernetes platform.
