Context

Resolves #5202

Problem

The current version of iroha_wasm_builder has a --release flag set by default for its output.
The input --optimize flag can be set that will apply -O -Os.
Still, it cannot produce a build in debug mode.

Solution

Changes in iroha_wasm_builder

This PR introduces a single flag --release that:

  • When set, apply --release -O -Os to the build.
  • When not set, produce a debug build.

Changes in build_wasm.sh

Now, build_wasm.sh produces a debug build by default. Flag --release can be added to build in optimized mode.

Checklist

  • I've read CONTRIBUTING.md.
  • (optional) I've written unit tests for the code changes.
  • All review comments have been resolved.
  • All CI checks pass.

Let's reject invalid args so that we don't type e.g. --releas lib and get unintended results

Changed to --profile={deploy, profiling} and --target={samples, libs}

Regarding whether named or position-based, either is acceptable but I personally prefer the shorter one

I think some CI workflows should keep --release build, at least iroha2-release.yml and maybe iroha2-custom-image.yml @BAStos525 ?

  • it should definitely be release for iroha2-release.yml
  • for the custom image it should use the PROFILE variable

In iroha2-release.yml we use the tag taken from github.ref_name - it's the tag name. Should any changes be introduced?

Only *.wasm quality is discussed here, which would only affect e.g. this line

CI will use release due to the need for additional resources (memory, fuel) and adjusted timeouts. Nevertheless, the debug flag can be set when building WASM.

I would like CI to use test when testing things and release (or deploy) when deploying. Yes, this will require you to adjust timeouts and limits in the test_network (don't modify parameters in genesis.json)

  1. --target=libs is easier to validate since only named arguments are used in build_wasm.sh
  2. --profile=${{ env.IROHA2_PROFILE }} works for deploy, but for PROFILE=profiling, it will require changes in memory, fuel, and timeouts. I think deploy should be used everywhere by default.

  1. ok, but how is someone to build a custom image with profile profiling now?

It was easier to validate when all arguments were named. I can revert if these must be position-based.

IMO you should use it for cargo install iroha. And you should set it to PROFILE: test

I'm of the opinion that whenever we're running tests we should run the test build

I don't have a very strong opinion on this too.

Speaking of the profile of irohad used by iroha_test_network, since the goal was to have a black-boxed environment close to what final users will have, it could be a point towards using release profile.
