Install takes forever(?) about lightning HOT 10 OPEN

Good idea, I'll try that if it happens again.

Oh I guess --silent is in CARGO_OPTS? Will try that next time.

I did a git clean -dfx, ./configure ... after this to see what would happen. This time it built quickly.

Update: the installer finished after about 15 minutes total. If this can't be made faster, then at least I think it should be more verbose and show some progress.

I suspect that was was cargo build --quiet --bin ... to take long time? I have the same behavior

This can be caused if you change your rust version, and the recompilation of all the crates (that are a few) is trigger

The lightning user has its own rust installation. I didn't change it, but maybe CLN did?

Current version is cargo 1.67.1 (8ecd4f20a 2023-01-10)

i think i saw a commit for cln that updated the rust version and it might be that cargo updated its repo which takes a long time (git resolving deltas). I gave it a quick search and found this: rust-lang/cargo#11014

No, we did not, we do not force the rustc version at the moment but it is possible that cargo is rebuilding.

If this happens could you run a patch version of the Makefile where you remove the cargo build --silent and use just cargo build? I can make a patch for you if you like

It's being slow again while upgrading to v24.02, but I can't find the cargo build --silent line.

Cargo version before install: cargo 1.67.1

from lightning.

It was a bit faster than last time, only about 5 minutes. Cargo version after install is unchanged.

git grep returned some item

cln-rpc/Makefile:12:    cargo build ${CARGO_OPTS} --example cln-rpc-getinfo
cln-rpc/Makefile:15:    cargo build ${CARGO_OPTS} --example cln-plugin-startup
cln-rpc/Makefile:18:    cargo build ${CARGO_OPTS} --example cln-plugin-reentrant
plugins/Makefile:257:   cargo build ${CARGO_OPTS} --bin cln-grpc

Cargo version after install is unchanged.

The cln-rust library is changed in this case, causing rebuilding (maybe) but I do not know why it is taking all this time :/
