We were only reusing the existing allocation if the new requested size was exactly the same as the fudged size of the block. This meant that realloc() could allocate a new block even though the new block would be identical to the old block. |

Serenity
Graphical Unix-like operating system for x86 computers.
About
I always wondered what it would be like to write my own operating system, but I never took it seriously. Until now.
Serenity is a love letter to '90s user interfaces, with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.
Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by me, for me, based on the things I like.
If you like some of the same things, you are welcome to join the project. It would be great to one day change the above to say "this is a system by us, for us, based on the things we like." :^)
I regularly post raw hacking sessions and demos on my YouTube channel.
There's also a Patreon if you would like to show some support that way.

How do I build and run this?
Go into the Toolchain/ directory and run the BuildIt.sh script. Then source the UseIt.sh script to put the i686-pc-serenity toolchain in your $PATH.
Once you've done both of those, go into the Kernel directory, then run makeall.sh, and if nothing breaks too much, take it for a spin by using run.
Otherwise, see the older step-by-step guide to building Serenity
