This is the 20th post of a series of blog posts tracking the development and progress of Redox, the Rust operating system. If you want to know more about Redox in general, visit our Github page.
With this post we restart the tradition of the weekly report and this one in particular is a catchup and it’s a big one! So bear with us please! ;)

What’s new in Redox?
@jackpot51 implemented timeouts.
@jackpot51 implemented an memory allocator that recycles frames when possible using an inner bump allocator if it cannot recycle. This new recycling allocator also allows the allocation of larger frames.
@jackpot51 added the
@jackpot51 implemented Implement CLOEXEC for root scheme and initfs.
@jackpot51 Other things include increasing the kernel heap size, fixed some bugs in the interrupts mechanism on serial devices, fixed
memmove(), fixed some deallocation issues, cleaned the debug scheme and added xargo support.
@jackpot51 added support to pass a live filesystem in the
FILESYSTEMenvironment var to the live scheme.
@pi-pi3 has improved the performance of
memcpy()family of functions.
@CWood1 has been working on adding AML support for the ACPI subsystem.
@InsidiousMind did some work on the PIT (Programmable interval timer). Now the PIT interrupt properly context switches fixing crashes in the kernel.
@bjorn3 added support for listing all schemes using the
There has been so much work ion shell that we have it’s own section for this issue. Ion is a shell for UNIX platforms, and is the default shell in Redox. It is still a work in progress, but much of the core functionality is complete. It is also currently significantly faster than Bash, and even Dash, making it the fastest system shell to date.
… and many small things!
- @jackpot51 added support for the VirtualBox guest driver and implemented resizing on it.
- @jackpot51 added initial support for the Atheros ALX ethernet driver.
- @jackpot51 added initial support for the BGA mode setting.
- @jackpot51 added scroll events to orbclient.
- @jackpot51 added support for absolute mouse events in the VESA driver.
- @jackpot51 done some fixes to the PS/2 driver related to interrupts.
- @jackpot51 added support for retrying commands to ps2d.
- @jackpot51 implemented
pathfor the e1000d and ahcid drivers.

TFS is a modular, fast, and feature rich next-gen file system, employing modern techniques for high performance, high space efficiency, and high scalability.
There has been enough work done in TFS that we added this section in this edition so you can have an idea about how the progress is going there.
First of all: Great news! @ticki has been working on many aspects of TFS and he considers that it is pretty near to functional. One of the great things is that as a product of this work several crates with interesting data structures and algorithms were created:
- chashmap - Concurrent hashmaps.
- cbloom - Concurrent bloom filters.
- lz4 - An implementation of lz4.
- speck - An implementation of SPECK cipher.
- tm - transactional memory.
- atomic-hashmap - Atomic hashmaps (you can read the blog post).
- mlcr - A machine-learning based cache replacement strategy.
- seahash - A hash function.
- concurrent - Hazard pointers implementation.
- TFS has a logo.
- There is a specification document.
- A bunch of blog posts on design: https://github.com/redox-os/tfs#resources-on-design.
And according @ticki there’s a ton of interesting things to write about, and eventually he will be doing an in-depth blog post about them.
- @ids1024 migrated
pkgto Hyper. Details here.
- @ids1024 made
pkgable to install packages from a given path. Details here.
- @ids1024 made possible to use the pkgutils library on Linux and install to custom destination. Details here.
- @ids1024 pkgutils now use the tar-rs library instead of the
tarbinary. Details here.
- @ids1024 added support for package metadata. Details here.
- @ids1024 added a
Packagestruct. Details here.
