v0.10.0

0.10.0

Okay, this one's a doozy.

Breaking

To build swww, you now need to make sure the wayland protocol .xml files can be found on your system through pkg-config. I couldn't get that to work in CI for nix-os, which is why build.nix has been deleted.

swww init, previously deprecated, has been properly deleted now. The correct way of initializing the daemon is calling swww-daemon directly.

Other than these, everything should be working the same as before.

Additions

• new --layer option for swww-daemon
• new --resize stretch option, by @rexept
• cache now stores the image filter, by @kerty0
• we can now read images from stanard input, by @iynaix
• new swww_randomize_multi.sh example script, by @cplir-c

Fixes

Note: because there were many changes between the previous version and this
one, some of these things may resurface as problems. Unfortunately, many of
these issues I either cannot reproduce in my system, or the whole application
has changed so much that testing them in isolation would be challenging.

• fixed output transforms
• animation timings could be slightly off
• examples scripts are more POSIX-friendly, by @fawn
• fixed memory leak and halted animation when connecting/disconnecting
  monitor, by @kerty0
• some stuff wasn't working when files were behind symlinks, fixed by @mendess
• fixed connecting to Wayland via WAYLAND_SOCKET, by @mstoeckl

Improvements

• reimplemented the communication from the client and the daemon from scratch,
  allowing for much more efficient data transfer
• the above was then made type-safe by @rkuklik
• using a custom log implementation that looks much nicer
• rewrote the transitions code to be more SIMD friendly -- will improve
  animation stuttering in some systems. Furthermore, and more importantly,
  the animations are now fast enough that we no longer need rayon as a
  dependency.
• more generaly, we have completed nuked the multi-threaded code.
  swww-daemon now only spawns a single thread, letting us get rid of every
  Arc wrapper, and other annoying, fragile, synchronization code.
• we are using rustix instead of the std as much as possible, for lower
  syscall overhead
• remove dependency on spin-sleep
• flake-lock by @JohnRTitor
• waybackend based implementation -- this is much more lightweight than
  wayland-rs, and lets us make the daemon very resource efficient.
• can now use hexcodes instead of image path, which we detect automatically,
  by @flick0

Other contributions

• fixes to some internal documentation by @JaKooLit, @Axlefublr, @filip-rs,
  @rexept, @Not-Glunk
• @rkuklik did a big refactor on the project's overall organization
• BREAKING CHANGE: dropped the init subcommand for the client, by
  @WhyNotHugo

Note there have also been other contributions that were rendered obsolete in the
meantime, since so much has changed from the last released version (in fact, the
last release was roughly a whole year ago!). The daemon codebase itself has gone
through 3 very large refactors, and now I am finally mostly satisfied with how
it looks. Unfortunately, this does mean some things will inevitably break. I
apologize in advance for any inconveniences.

On the other hand, I believe the rewrite has fixed some old-standing bugs we
have. Though those will have to be tested again on systems that can actually
reproduce them reliably.

I also apologize if I forgot to mention anything/anyone in the above summary. If
I missed your contribution, please feel free to open a PR adding it.
