And do dynamic buffer allocation for bin_export, removing 128k of
.rodata that I accidentally introduced earlier and reducing memory use
for parallel scans.
Static binaries now also include the minimal version of zstd, current
sizes for x86_64 are:
582k ncdu-2.5
601k ncdu-new-nocompress
765k ncdu-new-zstd
That's not great, but also not awful. Even zlib or LZ4 would've resulted
in a 700k binary.
* ZBS was reorganized around `Module` struct:
https://www.github.com/ziglang/zig/pull/18160 .
* Changes for ReleaseSafe: error return tracing is now off by default.

This is useful for building binary distributions because it allows
references to library dependendencies on the build machine to be
rewritten appropriately upon installation on the user's machine.
Zig also does this in their `build.zig`:

libc locale-dependent APIs are pure madness, but I can't avoid them as
long as I use ncurses. libtickit seems like a much saner alternative (at
first glance), but no popular application seems to use it. :(
I tried playing with zbox (pure Zig termbox-like lib) for a bit, but I
don't think I want to have to deal with the terminal support issues that
will inevitably come with it. I already stumbled upon one myself: it
doesn't properly put the terminal in a sensible state after cleanup in
tmux. As much as I dislike ncurses, it /is/ ubiquitous and tends to kind
of work.
The new data model is supposed to solve a few problems with ncdu 1.x's
'struct dir':
- Reduce memory overhead,
- Fix extremely slow counting of hard links in some scenarios
(issue #121)
- Add support for counting 'shared' data with other directories
(issue #36)
Quick memory usage comparison of my root directory with ~3.5 million
files (normal / extended mode):
ncdu 1.15.1: 379M / 451M
new (unaligned): 145M / 178M
new (aligned): 155M / 200M
There's still a /lot/ of to-do's left before this is usable, however,
and there's a bunch of issues I haven't really decided on yet, such as
which TUI library to use.
Backporting this data model to the C version of ncdu is also possible,
but somewhat painful. Let's first see how far I get with Zig.
