Bug reports
DragonFly Bug #3234. Respect RLIMIT_STACK for main thread under
pthread. I created a patch against libthread_xu that fixes this issue. This patch was required to makecrystalwork on DragonFly.DragonFly Bug #3235. A kernel panic I got while trying to install DragonFly on an encrypted disk.
Misc things
I am working on adding cummulative checksums to DragonFly’s HAMMER2 file-system under supervision of Matthew Dillon. So far it is working for files greater than 512 bytes. While HAMMER2 provides per-datablock checksums, cummulative checksums are per-file and allow for much faster tests on (potential) equality between two files.
Furthermore I was working on porting my implementation of the Evolvable Substrate algorithm from Rust to Javascript and added a nice UI that visualizes some aspects of the algorithm. The outcome: Evolvable Substrate Explorer.
