From 53711a86d9975ca399f3123d11cd757f35b91a3b Mon Sep 17 00:00:00 2001 From: Luke Yang Date: Wed, 9 Aug 2023 12:03:39 -0400 Subject: [PATCH] Add `container upgrade --check` function Previously, OS based on native containers could not retrieve the manifest difference between the current system container image and its corresponding remote container image without performing an actual upgrade. This PR solves this issue by allowing the manifest difference to be outputted when using the `rpm-ostree upgrade --check` command. A `ManifestDiff` struct needed to be retrieved using `ostree-rs-ext`, requring several new functions in both Rust and C that were bridged through CXX Bridge. The `cached_update` object also needed to be modifed and updated with the `ManifestDiff` in order to extend compatibility with other products using rpm-ostree. However, a notable difference between how the `--upgrade --check` function works for ostree based system and a native container based system is that native containers skip over the use of `checksums`. This is because rebasing to locally stored container images (as opposed to a remote repository) does not create a valid ostree refspec. A Rust unit test was implemented to confirm that a difference between two manifests (stored locally in the rust/test folder) can be successfully retrieved. A `kola` test was also implemented to confirm that running `rpm-ostree upgrade --check` returns the correct manifest difference for a potential upgrade. --- rpmostree-cxxrs.cxx | 55 +++++++++ rpmostree-cxxrs.h | 31 +++++ rust/src/deployment_utils.rs | 23 +++- rust/src/lib.rs | 26 +++- rust/src/sysroot_upgrade.rs | 95 ++++++++++++++- rust/test/manifest1.json | 1 + rust/test/manifest2.json | 1 + src/app/rpmostree-clientlib.cxx | 65 ++++++++++ src/app/rpmostree-clientlib.h | 2 + src/daemon/rpmostree-sysroot-upgrader.cxx | 21 +++- src/daemon/rpmostreed-deployment-utils.cxx | 67 ++++++++-- .../destructive/container-rebase-upgrade | 7 +- .../destructive/container-update-check | 115 ++++++++++++++++++ 13 files changed, 481 insertions(+), 28 deletions(-) create mode 100644 rust/test/manifest1.json create mode 100644 rust/test/manifest2.json create mode 100755 tests/kolainst/destructive/container-update-check diff --git a/rpmostree-cxxrs.cxx b/rpmostree-cxxrs.cxx index 42b1de545f..abe6ea20cd 100644 --- a/rpmostree-cxxrs.cxx +++ b/rpmostree-cxxrs.cxx @@ -1293,6 +1293,7 @@ enum class SystemHostType : ::std::uint8_t;
