Small optimisation to `--profile dev` wasm builds #1851

liamaharon · 2023-10-11T12:52:58Z

wasm-builder was adjusted to default to building wasm blobs in release mode even when cargo is in debug because debug wasm is too slow.

A side effect of this was .compact and .compact.compressed getting built when the dev is running build in debug, adding ~5s to the build time of every wasm runtime.

I think it's reasonable to assume if the dev is running debug build they want to optimise speed and do not care about the size of the wasm binary. Compacting a blob has negligible impact on its actual performance.

In this PR, I adjusted the behavior of the wasm builder so it does not produce .compact or .compact.compressed wasm when the user is running in debug. The builder will continue to produce the bloaty wasm in release mode unless it is overriden with an env var.

As suggested by @koute in review, also refactored the maybe_compact_wasm_and_copy_blobs into multiple funuctions, and renamed things to better support RISC-V in the future.

There is no T-runtime label so @KiChjang told me to put T1-FRAME :)

This PR fixes a subtle bug in `wasm-builder` first introduced in #1851 (sorry, my bad! I should have caught this during review) where the status code of the `cargo` subprocess is not properly checked, which results in builds silently succeeding when they shouldn't (that is: if we successfully build a runtime blob, and then modify the code so that it won't compile, and recompile it again, then the build will succeed and silently use the *old* blob). cc @athei This is the bug you were seeing. [edit]Also fixes a similar PolkaVM-specific bug where I accidentally used the wrong comparison operator.[/edit]
