fix(dynamix): align mover progress values with emhttpd

[SimonFair]

Summary

Mover Progress now uses emhttpd's yes/no contract end to end while keeping the user-facing Enabled and Disabled labels, including for values written by 7.4.0-beta.2.

Why This Exists

In 7.4.0-beta.2, a missing shareMoverProgress value defaults to no in runtime state, but the WebGUI offered enabled and disabled. A page Apply could therefore persist either legacy value even when the user had not touched Mover Progress. Those values select neither new option, so the browser falls back to Enabled while progress remains off. A deliberately selected Disabled value can show the same incorrect Enabled state.

Resolution

The settings form submits yes or no while retaining the Enabled and Disabled labels. Before rendering, the form normalizes only exact yes to yes and treats every other value as no, so legacy values display Disabled and are cleaned up on the next Apply. The mover and its progress consumers use the same exact yes check, so no and missing values leave progress disabled without changing mover process-state reporting.

Reviewer Considerations

• emhttp/plugins/dynamix/MoverSettings.page is the persistence and compatibility boundary: the submitted values are now yes and no, and legacy beta.2 values render as Disabled.
• The form does not rewrite share.cfg during display; the next Apply writes the canonical value.
• sbin/mover reads the persisted setting at startup and only creates progress status when it is yes.
• Nchan suppresses progress payloads when the runtime setting is not yes, while Array Operations only subscribes to the progress channel for yes.
• Existing progress rows remain hidden when progress is disabled.

Behavior Changes

• Missing, enabled, disabled, or no values display Disabled and do not publish mover progress.
• Selecting Enabled submits shareMoverProgress=yes to emhttpd.
• Selecting Disabled submits shareMoverProgress=no to emhttpd.
• A yes value enables mover totals and live progress in Array Operations.
• A legacy value is corrected to yes or no when the user next applies the settings page.

Implementation Summary

• Updated the Mover Settings option values and default.
• Normalized legacy Mover Progress values before calling mk_option.
• Updated mover progress detection and fallback values.
• Gated Nchan progress publication and the Array Operations progress subscriber on the runtime yes value.

Verification

• php -l emhttp/plugins/dynamix/MoverSettings.page
• php -l emhttp/plugins/dynamix/ArrayOperation.page
• php -l emhttp/plugins/dynamix/nchan/parity_list
• bash -n sbin/mover
• bash -n sbin/mover.old
• git diff --check
• Focused contract assertions for the settings normalization, option values, and exact yes gates passed.

Risk

Low; the change is limited to the existing mover-progress setting and its established UI/runtime consumers. Hardware-backed mover QA is still appropriate before merge.

Related to OS-866.

Summary by CodeRabbit

• Bug Fixes
  • Mover progress updates now follow the configured setting and are suppressed when progress reporting is disabled.
  • If no setting is configured, Mover Progress defaults to Disabled.

Walkthrough

Mover Progress now uses shareMoverProgress, which defaults to no. The settings page, mover process, Nchan status publishing, and page subscriber use yes to enable progress reporting.

Changes

Mover Progress setting and reporting

Layer / File(s)	Summary
Read and normalize Mover Progress setting emhttp/plugins/dynamix/MoverSettings.page, sbin/mover	The settings page keeps the exact value yes and coerces other values to no. The mover process uses yes to enable progress reporting and no as its default.
Gate progress publishing and display emhttp/plugins/dynamix/nchan/parity_list, emhttp/plugins/dynamix/ArrayOperation.page	The Nchan loop handles mover progress only when the process state is 2 and sharing is enabled. The page emits the mover-status subscriber only when sharing is enabled.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 949ae

The previously identified settings and parsing risks are resolved, with no remaining concrete merge-blocking issue.
