Issue running wasm compilation out-of-the-box

[jonbae]

when running the docker command to compile

docker run --rm -v "$(pwd)":/code \
  --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \
  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
  cosmwasm/workspace-optimizer:0.12.3

I get a error of

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 20, kind: NotADirectory, message: "Not a directory" }', src/main.rs:58:14
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I have done npm install in the root directory on all the necessary packages for base-helpers.ts to run.

I have also run the command RUSTFLAGS="-C link-arg=-s" cargo build --release --target=wasm32-unknown-unknown --locked as suggested to debug but all of the contracts compile fine.

currently stuck and would appreciate help.

Rust: rustc 1.56.1
OS: windows subsystem for linux

I assume you're seeing a log such as Building "contracts/base-helpers.ts" ... right before what you pasted as an error. This happens because in the contracts directory which rust is trying to compile there is a typescript file. This is a recent change made by @findolor - maybe he can shed more light on it ;)

Thanks for bringing this up! You are right this is expecting every item to be a directory in contracts.
Opened a PR to fix this one.

Thank you for the report. This is a missing is directory check in https://github.com/CosmWasm/rust-optimizer/blob/v0.12.3/build_workspace/src/main.rs#L28-L32

@maurolacy could you look into this?

I believe this has since been fixed.
Both in a more robust rust-optimiser as well as in removing the base_helpers.ts file.

Can this be closed?

[webmaster128]

True, fixed in 0.12.4 with this function: https://github.com/CosmWasm/rust-optimizer/blob/v0.12.4/build_workspace/src/main.rs#L22-L31.

I think it can be closed once all references to workspace-optimizer in this project are updated.
