moon

Release Notes

🚀 Updates

• The Pkl modules generated since v2.6.3 type lists and maps as Pkl's amendable Listing and Mapping only, as Pkl recommends for configuration data. A config that amends its module, and assigns a List, Set, or Map to a setting, must convert it with toListing() or toMapping(), or create it with new Listing { ... } instead. Updated the Pkl docs and examples to match.
• moon now handles SIGHUP, which is sent when the terminal is closed, like SIGTERM. Running tasks receive SIGHUP, and are force killed after pipeline.killProcessThreshold, the pipeline is marked as terminated, and moon exits with code 129. Previously moon was killed immediately, so a kill -HUP left its tasks running. On Windows, closing the console window is handled the same way, instead of aborting the pipeline with code 131.

🐞 Fixes

• Fixed an issue where moon exited with code 1 and printed "Failed to flush buffered output to console" when the command reading its output exited early (a broken pipe), instead of exiting quietly with code 141.
• Fixed an issue where, with the daemon enabled, a task would fail with "Failed to make daemon RPC call" when its stdout/stderr, or its list of output files, was larger than 4 MiB. The daemon now accepts messages up to 256 MiB, and if archiving or hydrating outputs through the daemon fails, it's done in-process instead of failing the task.
• Fixed an issue where the daemon was silently never used in development containers (like VS Code Dev Containers), yet was used in CI environments that aren't Docker containers (like Kubernetes pods), where it outlived the run. The daemon is now used in development containers, is never used in CI, and the reason it was skipped is logged at the debug level.
• Fixed an issue where hasher.ignorePatterns and hasher.ignoreMissingPatterns were matched against absolute file paths instead of workspace relative paths. A pattern that matched a parent directory of the workspace, like **/.worktrees/** for a git worktree nested in the repository, ignored every input, so tasks were always cached and restored stale outputs. Patterns without a **/ prefix, like docs/**, now match as well.
• Fixed an issue where .env files with multiple trailing comment markers (#) would not parse correctly.

⚙️ Internal

• Updated the npm release to publish @moonrepo/cli after the @moonrepo/core-* packages, and to skip versions that are already published, so a failed release can be re-ran. Previously a failure could publish a @moonrepo/cli version whose binaries were never published.

Release Notes

🛡️ Security

• Distrusted the 8 compromised eMudhra intermediate CA keys, and removed the "emSign ECC Root CA - G3" root from our bundled root certificates. Previously, anyone in a position to intercept a connection could use these keys to forge a certificate for any host, and proto would accept it on Linux, and on all platforms for plugins that make requests through Extism's built-in HTTP functions.
  • Hosts with certificates that chain to "emSign ECC Root CA - G3" will now fail TLS verification.
  • Requests to OCI registries on Linux still rely on the system certificate bundle, so update your ca-certificates package.

🐞 Fixes

• Fixed an issue where changing any setting in .moon/workspace.*, like codeowners, invalidated the cache of every task. Only .moon/extensions.* and .moon/toolchains.* are now implicit task inputs.
• Fixed an issue where a task that stopped before running its command, because another task failed or a requirement check failed, would be cached on the next run, reusing outputs from its previous inputs.
• Fixed an issue where deleted optional: true file outputs were not restored on a cache hit, when the hash matched the task's last run.
• Fixed an issue where outputs partially restored by a failed cache hydration could be reused as a cache hit on the next run.

Release Notes

🐞 Fixes

• Fixed an issue where moon run exited 0 and counted a running task as skipped after SIGINT or SIGTERM. The process now exits 130 or 143, and the summary no longer calls that task skipped.
• Fixed an issue where a wait dependency on an interactive task was allowed, instead of failing with an error, as an interactive task runs in isolation, so nothing can run alongside it. The error was only raised when the asyncGraphBuilding experiment was disabled.
• Fixed an issue where the task hasher logged "only files can be hashed" warnings for directories (or symlinks to directories) that match hasher.ignorePatterns.

🧰 Toolchains

• Python
  • Fixed missing project dependencies for versioned requirements using workspace = true in the project's [tool.uv.sources] with uv.
  • Prevented self-dependency cycles from optional requirements.
• Rust
  • Fixed docker prune failing with "unknown variant custom-build" when a crate has a build script, example, bench, or other unsupported target kind.
  • Fixed docker scaffold leaving an empty src/main.rs in library crates, which failed builds with "main function not found". Only the crate's existing lib and bin targets (including src/bin) are now stubbed.
• TypeScript
  • Fixed pruneProjectReferences removing references from the root tsconfig.json when a root-level project uses it as its project config.
