| In this release, we focused primarily on rewriting our task runner, and improving our console. | ||

|
|
||
| ## New task runner implementation | ||
|
|
||
| It's been over a month since our last release, but we've been really busy rewriting our task runner | ||
| from the ground up! In other build systems, a task runner is typically the orchestator that runs | ||
| multiple tasks and manages their state. In moon this is known as the action pipeline (or just | ||
| pipeline), and a task runner is simply the execution of a single task. However, executing a single | ||
| task is quite involved, as we need to generate a unique hash, check the cache, hydrate outputs if a | ||
| cache hit, actually execute the task as a child process, and much more! | ||
|
|
||
| Task running is some of the oldest code in moon, as it was part of the initial MVP. Because of this, | ||
| it hasn't changed much, but moon has grown quite large and it was time to revisit it with better | ||
| design patterns and practices. Furthermore, since the task runner is so critical to moon itself, we | ||
| wanted to ensure it worked correctly, and spent more time than usual implementing, testing it, and | ||
| verifying edge cases. | ||
|
|
||
| With this new task runner, we... | ||
|
|
||
| - Improved handling and reliability of output archiving (cache miss) and hydration (cache hit). | ||
| - Streamlined the task execution (child process) flow. | ||
| - Increased performance by optimizing or removing certain code paths. | ||
|
|
||
| > If you're interested in how the task runner was implemented, feel free to take a look at the | ||
| > [Rust crate](https://github.com/moonrepo/moon/tree/master/nextgen/task-runner), and the | ||
| > [pull request](https://github.com/moonrepo/moon/pull/1463) itself. | ||
| ### Fine-grained operations | ||
|
|
||
| A major goal of moon is bubbling up information to the user that is applicable to the current | ||
| workflow, but what about when that workflow must be debugged or optimized? At that point, it was | ||
| almost impossible without digging into the source code. | ||
|
|
||
| To make a step in this direction, as part of the new task runner we now track timing information for | ||
| individual parts of the run execution, and we're calling these parts operations. An operation is | ||
| anything from generating a hash, creating a tarball archive, unpacking the archive (cache | ||
| hydration), task execution (the child process), and more. | ||
|
|
||
| This timing information is useful in figuring out why a certain task is slower than expected, and | ||
| which operation is actually causing the slowness. It also helps to uncover which operations were | ||
| actually ran for an action, which were skipped, so on and so forth. At this point in time, the | ||
| operations information is only included in the run report, located at `.moon/cache/runReport.json`. | ||
| In the future, we plan to display this information in a nice UI. | ||
|
|
||
| For an example of this in action, here's a list of all operations that were executed when running | ||
| the `build` task for our website. | ||
|
|
||
| ```json | ||
| [ | ||
| { | ||
| "duration": { | ||
| "secs": 0, | ||
| "nanos": 609156875 | ||
| }, | ||
| "finishedAt": "2024-05-27T00:14:54.286628", | ||
| "meta": { | ||
| "type": "hash-generation", | ||
| "hash": "10606e37c5e6ab4008007b30275f1682bae32dca71650ce173eb386d5b6c3309" | ||
| }, | ||
| "startedAt": "2024-05-27T00:14:53.677526", | ||
| "status": "passed" | ||
| }, | ||
| { | ||
| "duration": { | ||
| "secs": 0, | ||
| "nanos": 32834 | ||
| }, | ||
| "finishedAt": "2024-05-27T00:14:54.286667", | ||
| "meta": { | ||
| "type": "output-hydration" | ||
| }, | ||
| "startedAt": "2024-05-27T00:14:54.286634", | ||
| "status": "skipped" | ||
| }, | ||
| { | ||
| "duration": { | ||
| "secs": 15, | ||
| "nanos": 789003125 | ||
| }, | ||
| "finishedAt": "2024-05-27T00:15:10.075113", | ||
| "meta": { | ||
| "type": "task-execution", | ||
| "command": "docusaurus build", | ||
| "exitCode": 0 | ||
| }, | ||
| "startedAt": "2024-05-27T00:14:54.286950", | ||
| "status": "passed" | ||
| }, | ||
| { | ||
| "duration": { | ||
| "secs": 17, | ||
| "nanos": 214634292 | ||
| }, | ||
| "finishedAt": "2024-05-27T00:15:27.289995", | ||
| "meta": { | ||
| "type": "archive-creation" | ||
| }, | ||
| "startedAt": "2024-05-27T00:15:10.075686", | ||
| "status": "passed" | ||
| } | ||
| ] | ||
| ``` | ||
|
|
||
| Because of these new operations, we can clearly see above that the archive creation process is | ||
| taking 17 seconds, which is 2 seconds longer than the build itself! Without this information, we | ||
| would have never known that the archive was taking this long, but now we do, and we can optimize it | ||
| in a future release! | ||
|
|
||
| ### Run summaries | ||
|
|
||
| Because of the new task runner and the new console ([below](#new-console-reporting-layer)), we have | ||
| the ability to bubble up more information than before. Based on requests from the community, we've | ||
| taken the output from [`moon ci`](/docs/commands/ci) and applied it to both | ||
| [`moon check`](/docs/commands/check) and [`moon run`](/docs/commands/run) behind the `--summary` | ||
| flag. | ||
|
|
||
| When this flag is passed, we will now summarize all actions that have ran in the pipeline (not just | ||
| task related ones), and include failed tasks for review. For example, here's the output of | ||
| `moon check website --summary` on moon's repository. | ||
|
|
||
| ``` | ||
| $ moon check website --summary | ||

||
| ## New console reporting layer | ||
|
|
||
| For the most part, when something in moon needed to be printed to the console, we would simply print | ||
| it directly at that point in time, anywhere within the codebase. While this worked, it made it | ||
| difficult to orchestrate output from different parts of the codebase, and in the context of Rust, | ||
| each call to stdout/stderr [locks the I/O stream](https://nnethercote.github.io/perf-book/io.html), | ||
| resulting in performance loss. | ||
|
|
||
| To work around this, in [v1.21](./moon-v1.21) we implemented a new | ||
| [console layer](https://github.com/moonrepo/moon/tree/master/nextgen/console) that buffers all stdio | ||
| writes, and prints them on 100ms intervals. This avoids locking on every call, and instead batches | ||
| them. To expand on this further, in this release we've implemented a new | ||
| [reporter layer](https://github.com/moonrepo/moon/tree/master/nextgen/console-reporter), with a | ||
| well-defined interface that is used to print checkpoints (the 4 squares), and status updates from | ||
| the action pipeline (and the new task runner). | ||
|
|
||
| This reporter layer enables new console UI implementations in the future based on your preferences. | ||
| For example, an [interactive UI](https://ratatui.rs/) composed of tables, tabs, and more, | ||
| representing the current state of the pipeline. | ||
|
|
||

| of changes. | ||
|
|
||
| - Greatly reduced the amount of concurrent locks being held during task execution. May see slight | ||
| performance improvements. | ||
| - Updated external configuration files (via https extends) to be cached for 24 hours. | ||
| - Updated macOS binaries to be built on macos-12 instead of macos-11. | ||
| - Updated proto to v0.35.4 (from v0.34.4). |
