chore(3p/sources): Bump channels & overlays * agenix has not been updated (https://github.com/ryantm/agenix/pull/241). * wasm-bindgen bumped to 0.2.92 in Rust WASM projects * 3p/lisp: port lispPackages from stable channel The Lisp package set we are using (`pkgs.lispPackages`) is the "old old" package set, whereas we were supposed to have been using `pkgs.lispPackages_new` (which is the "old new" package set). Either way we missed that train, and now there's a "new new" package set, but with a twist: Lisp packages in nixpkgs are now tied to their compilers, so the most generic way to access them seems to be from `pkgs.sbclPackages`. Switching to the packages from the "new new" package set doesn't work: Lots of stuff stops building if we just switch the sources over, and not everything is trivially fixable. For now we stay on the lispPackages from the stable channel. We need to look into the migration later. Or rewrite panettone. * tvix: update generated protobuf files * 3p/nixpkgs: pick trunk from stable channel; newer versions try to read files and do network I/O during build, but don't print enough details in error messages to figure out why. * 3p/overlays: remove tdlib override (nixpkgs is currently new enough) * 3p/overlays: override telega.el sources while updates are lagging in nixpkgs * users/flokli/ipu6-softisp: update firmware paths, which NixOS now stores zstd-compressed.

feat(nix/buildLisp): add ecl Adds ECL as a second supported implementation, specifically a statically linked ECL. This is interesting because we can create statically linked binaries, but has a few drawbacks which doesn't make it generally useful: * Loading things is very slow: The statically linked ECL only has byte compilation available, so when we do load things or use the REPL it is significantly worse than with e. g. SBCL. * We can't load shared objects via the FFI since ECL's dffi is not available when linked statically. This means that as it stands, we can't build a statically linked //web/panettone for example. Since ECL is quite slow anyways, I think these drawbacks are worth it since the biggest reason for using ECL would be to get a statically linked binary. If we change our minds, it shouldn't be too hard to provide ecl-static and ecl-dynamic as separate implementations. ECL is LGPL and some libraries it uses as part of its runtime are as well. I've outlined in the ecl-static overlay why this should be of no concern in the context of depot even though we are statically linking. Currently everything is building except projects that are using cffi to load shared libaries which have gotten an appropriate `badImplementations` entry. To get the rest building the following changes were made: * Anywhere a dependency on UIOP is expressed as `bundled "uiop"` we now use `bundled "asdf"` for all implementations except SBCL. From my testing, SBCL seems to be the only implementation to support using `(require 'uiop)` to only load the UIOP package. Where both a dependency on ASDF and UIOP exists, we just delete the UIOP one. `(require 'asdf)` always causes UIOP to be available. * Where appropriate only conditionally compile SBCL-specific code and if any build the corresponding files for ECL. * //lisp/klatre: Use the standard condition parse-error for all implementations except SBCL in try-parse-integer. * //3p/lisp/ironclad: disable SBCL assembly optimization hack for all other platforms as it may interfere with compilation. * //3p/lisp/trivial-mimes: prevent call to asdf function by substituting it out of the source since it always errors out in ECL and we hardcode the correct path elsewhere anyways. As it stands ECL still suffers from a very weird problem which happens when compiling postmodern and moptilities: https://gitlab.com/embeddable-common-lisp/ecl/-/issues/651 Change-Id: I0285924f92ac154126b4c42145073c3fb33702ed Reviewed-on: https://cl.tvl.fyi/c/depot/+/3297 Tested-by: BuildkiteCI Reviewed-by: tazjin <mail@tazj.in> Reviewed-by: eta <tvl@eta.st>
