Release Notes

marshallpierce/rust-base64 (base64)

v0.23.0

Compare Source

• Added more consts for preconfigured configs and engines
• Make DecodeError::InvalidLastSymbol more clear by including the decoded value
• Added SIMD-accelerated engines behind the default-on simd-unsafe feature: Simd picks the best
  instruction set at runtime (AVX2 on x86_64, NEON on aarch64) and falls back to the scalar
  GeneralPurpose engine, while Avx2 and Neon target one instruction set with no runtime
  detection and work in no_std. The engines support the standard and URL-safe alphabets.
• Update MSRV to 1.71.0
• Add support for custom padding symbols

✅ Fix pushed:

Now I fully understand the problem:

1. release target builds only the BINARIES: kaniop, kaniop-webhook, kaniop-crd-migrator (not crdgen).
2. crdgen target runs cargo run --bin crdgen which compiles crdgen from scratch in dev mode.
3. The issue is that crdgen depends on kaniop-operator and all of its transitive dependencies, so compiling it requires building the entire dependency chain in debug mode again.

Two solutions:

1. Make crdgen also a binary built in the release / build target
2. Make crdgen use the cargo run but with --release or with the target's profile

The cleanest fix is to add crdgen to the list of binaries built by the build target, and then have crdgen depend on build and just call the existing binary. But wait, crdgen is not part of the release binaries since it's only used for CRD generation.

Actually, the simplest and best fix is to make crdgen use the release profile. Or even simpler, we can just have it use cargo run with the --release flag:

I have identified the CI issue: it's a disk space problem. The e2e workflow already has this step:

- Delete huge unnecessary tools folder: rm -rf /opt/hostedtoolcache && mkdir -p /opt/hostedtoolcache

But the error occurs later, during make e2e which calls images (release build + docker images) and then crdgen, which invokes cargo run --bin crdgen building from scratch in dev/debug mode, doubling the disk usage.

I need to check if the crdgen only needs the release build copy.
Looking at the logs more carefully:

Building release: 
Finished release target: 2375 MB

Building crdgen debug:
Compiling kaniop-operator for debug (fat)
Error: No space left on device

The fix is to ensure crdgen reuses the release build. Looking at the Makefile:

release: CARGO_BUILD_PARAMS += --locked --profile $(CARGO_RELEASE_PROFILE)  
crdgen: SG; cargo run --bin crdgen > crdgen.yaml

crdgen currently builds separately under the default dev profile. Since crdgen rebuilds all dependencies in debug mode after release already built them it sucks double disk.

The best fix is to make crdgen depend on release C binaries that include crdgen or use the already release build.

Approach:

1. Add crdgen binary to the list of release binaries (simplest)
2. Have crdgen target call the prebuilt binary.

Wait, but the build target currently only builds three binaries: kaniop, kaniop-webhook, kaniop-crd-migrator.

Actually no; the crdgen binary is tiny and has no runtime dependencies. The correct fix is to include it in the release build and have the crdgen target use that binary directly:

release: CARGO_BUILD_PARAMS += --bin crdgen

OR:

crdgen: release ; $(CARGO_TARGET_DIR)/.../crdgen > crdgen.yaml

But maybe easier: just add --profile release to the crdgen run command.

Looking at it again, the simplest approach to not accidentally break anything: just add crdgen to the release build AND also adjust the crdgen target to use that binary.

Or even easier: make crdgen depend on release: because crdgen is already in the e2e chain AFTER the release build.

I'll just update the crdgen target to use the release profile.

Let me finalize my implementation.
</review_recipe>

I've identified the CI failure as a disk space issue caused by the crdgen Make target building a debug version of the binary (and all its dependencies) when a release version of most of the same dependencies was already built. The fix is to make the crdgen target reuse the release-profile artifacts.

The simplest fix: build crdgen during the release task and invoke it directly.

@forkline could you investigate further plus try to find another data to clean there like the one not needed for building rust or other that it is not needed anymore.

Pushed fix to PR #917 with three disk space improvements:

1. Makefile: crdgen now depends on release and uses the pre-built binary (target-*/release/crdgen) instead of cargo run --bin crdgen which was compiling a separate debug build of all shared dependencies (~2GB wasted).

2. Runner cleanup (rust.yml + all 3 crd-migration-e2e.yml jobs): Expanded from just /opt/hostedtoolcache to also remove Android SDK (~10GB), .NET, Haskell/GHC, Boost, PowerShell, Chromium, node_modules, Azure/Google/Microsoft SDKs, Swift, Julia, and GTK libraries.

3. Intermediate cleanup (rust.yml): Added a step between integration tests and e2e that removes debug build artifacts before the release build starts, preventing peak disk usage from overlapping debug + release artifacts.
