From 9aeedb133b479530e8ab55461042b4b1bd4ca7de Mon Sep 17 00:00:00 2001 From: Jason Hall Date: Sun, 8 Jun 2025 15:01:38 -0400 Subject: [PATCH] feat: add configurable multi-part uploads to oci-distribution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Added `use_chunked_uploads` field to ClientConfig (default: true) - Modified push_blob to respect the chunked upload configuration - Configured krust to disable chunked uploads for better registry compatibility - Added comprehensive tests for the new configuration option This allows callers to control whether chunked/multi-part uploads are used, which improves compatibility with registries that may not support them well. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- Makefile | 12 ++ src/registry/mod.rs | 6 +- src/registry/tests.rs | 15 +++ vendor/oci-distribution/src/client.rs | 152 ++++++++++++++++++++++++-- 4 files changed, 176 insertions(+), 9 deletions(-) diff --git a/Makefile b/Makefile index f41ab0e..61e7fb8 100644 --- a/Makefile +++ b/Makefile @@ -94,3 +94,15 @@ check-code: # Run all checks (format, lint, test) check: check-fmt lint test + +push-ttl: + @echo "Building and pushing to ttl.sh..." + KRUST_REPO=ttl.sh/jason cargo run build example/hello-krust + +push-gar: + @echo "Building and pushing to Google Artifact Registry..." + KRUST_REPO=us-central1-docker.pkg.dev/jason-chainguard/krust cargo run build example/hello-krust + +push-cgr: + @echo "Building and pushing to Chainguard registry..." + KRUST_REPO=cgr.dev/imjasonh.dev/krust cargo run build example/hello-krust diff --git a/src/registry/mod.rs b/src/registry/mod.rs index 8e9dbe5..5c060dd 100644 --- a/src/registry/mod.rs +++ b/src/registry/mod.rs @@ -14,7 +14,11 @@ pub struct RegistryClient { impl RegistryClient { pub fn new() -> Result { - let client = Client::new(oci_distribution::client::ClientConfig::default());
