Closes #1957.

Adds two per-template flags that let an admin remove the Dry Run (--check) and Diff (--diff) checkboxes from the task dialog, for deployments that expose Semaphore to end users who have no use for them.

The original issue asked for three things; two are already resolved (Debug is gated by allow_debug, and the "Advanced" link no longer exists), Dry Run and Diff were the remainder.

Why hide_* rather than allow_*

allow_* would match the neighbouring allow_debug, but it would silently remove the checkboxes for existing templates on upgrade. task_params is stored as a JSON blob and FillParams unmarshals it into the struct, so a key absent from templates created before this change unmarshals to false. Inverting the polarity makes the zero value the backwards-compatible one: "absent" means "false" means "not hidden" means "current behaviour".

Happy to switch to allow_* if you'd prefer the uniform naming. Or to rework a version that keeps both the naming and the compatibility at the cost of complexity: *bool with nil meaning "allowed". It costs a helper method that every read site must go through and a computed getter/setter for the tri-state checkbox.

Tests

TestGetPlaybookArgs_HideDryRunAndDiff covers the flag matrix, including a template whose task_params is nil.

go test ./services/tasks/ -run TestGetPlaybookArgs_HideDryRunAndDiff -v -count=1

Verified manually against a local instance: the checkboxes appear and disappear per template, and the setting round-trips through the template edit form.

Ran the dredd suite against a local instance before and after the change, with identical results, so no regression.

Notes

  • The flags are enforced in local_executor.go, not only in the UI.
  • Ansible only. TaskParamsTerraformForm.vue has its own params and is untouched.

Summary by CodeRabbit

  • New Features

    • Added template settings to hide dry-run output and diff options.
    • Administrators can configure whether these options appear in task forms.
    • Hidden options are no longer passed to Ansible during task execution.
    • Added English labels for the new settings.
  • Bug Fixes

    • Ensured task execution respects template-level visibility settings for dry runs and diffs.

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds template-level controls for hiding dry-run and diff options. The frontend conditionally displays these controls and task options. The local executor omits --check and --diff when the corresponding template settings are enabled.

Template option controls

Layer / File(s) Summary
Template configuration and task form
db/Template.go, web/src/lib/constants.js, web/src/lang/en.js, web/src/components/TemplateForm.vue, web/src/components/TaskParamsAnsibleForm.vue
AnsibleTemplateParams now includes HideDryRun and HideDiff. Template forms expose these settings, and task forms hide the related options when enabled.
Executor enforcement and validation
services/tasks/local_executor.go, services/tasks/local_executor_test.go
getPlaybookArgs omits --check and --diff according to template settings. Tests cover default, nil, individual, and combined settings.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 0def8

The template settings hide the Dry Run and Diff controls, but direct task arguments can still re-enable those flags, so the restriction is not fully enforced for users who can supply CLI arguments. This is a bounded correctness issue that should be addressed with explicit owner follow-up.

Reject hidden Ansible flags in task CLI arguments

When HideDiff or HideDryRun is enabled, reject --diff or --check in taskArgs before appending them. Task arguments accept arbitrary names and are appended after the hide checks.
