This commit introduces a new shell helper function, `resolve_dep_version`, which retrieves the version of a specified Go module from the project's `go.mod` file. As part of this change: - All usages of `knative.dev/toolbox/...@latest` have been pinned to a specific commit (`@bc7e152`) to ensure reproducible builds and prevent unexpected failures due to upstream changes. - The shell script test harness has been improved to more reliably locate the `go` executable, making the tests more robust across different environments.
The `go_run` helper function is updated to set `GOTOOLCHAIN=auto` when executing toolbox tools.
This change corrects the logic to set `GOTOOLCHAIN=auto` for any package within the `knative.dev/toolbox` module.
This commit makes two corrections to the test suite in `sharedlib_test.go`: 1. In the main test runner, the `errOut` variable (which captures stderr) was incorrectly being checked against the `outputTypeStdout` constant. This has been corrected to `outputTypeStderr` to ensure test failure messages accurately reflect the stream being checked. 2. Potential errors from `io.ReadAll` when capturing stdout and stderr in the `goRunHelpPrefetcher` were being ignored. Assertions have been added to ensure that any errors during these reads are caught, making the test more robust.
