As a speaker of Greek, I’ve been fixing issues in the handling
of non-ASCII characters for over 40 years, using techniques ranging from
simple lookup tables to dynamic patching of in-memory images.
Here’s how I debugged and fixed the handling of UTF-8 characters
in the git grep command, which was broken for almost a decade.
Thanks to a tweet
by Aaron Toponce I learned about the Linux
/dev/full pseudo-device.
Write system calls to it always fail with a ENOSPC (no space on device)
error.
With it finding software that doesn’t check for failed writes is a
piece of cake.
Let’s see this in action.
