Before the changes intorducing the new wasmtime bindings we relied on an downloaded static library libwasmtime.a. Now that the bindings are introduced, we do not rely on it anymore, so all references to it can be removed.
Nix development environment
The *.nix files at the project root and under dist/nix implement a
Nix-based
development environment for Scylla.
Note that there is presently no support for building installable
artifacts with nix build, or anything suitable for incorporation
into the Nixpkgs collection (that's "just" a matter of implementing
installPhase in default.nix). This is just a development
environment that is predictable, is independent from the state of the
host distribution, and does not require entering a container.
gdb with green thread debugging support is included, plus other
assorted debugging tools.
Compilers are transparently wrapped to use ccache and distcc, if
you have those configured.
Basic usage
If you have Nix flake support enabled (recommended!), enter the
environment using nix develop .. Otherwise, use nix-shell ..
$configPhase will configure Scylla for building (it just invokes
./configure.py --disable-dpdk). Then use ninja to build,
test.py to run unit tests, etc., as usual.
Direnv (optional)
Using direnv is recommended to make life more convenient. Create
.envrc at the project root with the contents:
nix_direnv_watch_file default.nix
nix_direnv_watch_file shell.nix
for f in $(find dist/nix/ -type f); do
nix_direnv_watch_file $f
done
use flake
For non-flake usage, replace the last line with use nix.
