Migrate Timezone and Hidden Site PIN menus; harden menu framework against set -e; bump to v2.1.0
Two more menus migrated onto lib/menu.sh + lib/config.sh, chosen specifically because neither touches config.json - a third and fourth shape for the framework (a system command via timedatectl, and a flat PIN file), on top of Sites' list CRUD and Display's JSON toggles. - menus/timezone.sh: also replaces the legacy script's hand-numbered 18-entry case statement with a plain data list (TIMEZONE_COMMON_ZONES) plus one handler that reads the number run_menu hands it - adding or removing a zone never touches numbering anywhere else. Required a small run_menu addition: handlers now receive the chosen 1-based number as $1, so one handler can serve a whole data-driven list instead of needing a wrapper function per entry. - menus/hidden_pin.sh: set/disable/reset the PIN gating hidden pages. Testing menus/timezone.sh surfaced a real bug before it ever shipped: this whole tool runs under `set -e`, and set_timezone() rejecting an invalid zone via a bare `return 1` as its last statement took down the *entire* install.sh session, not just that one action - a single typo would silently drop the user back to their shell. Fixed at the framework level in lib/menu.sh (run_menu now absorbs a failed handler's exit code) rather than patching set_timezone alone, since any future menu could hit the same trap. Verified against the real install.sh as a genuine non-root user: an invalid timezone now logs an error and redraws the Timezone menu instead of killing the session (confirmed exit code 0 at the end of the run). Note this specific hazard was introduced by this session's own return-1 idiom, not inherited from the legacy script, which never uses a bare return 1 in these functions. Also per the user: left the old configure_sites/configure_touch_controls/ configure_navigation_security/configure_optional_features functions in ubuntu-based-kiosk.sh untouched for now (still carrying the v2.0.0 settings-clobber and reorder bugs) rather than removing them - they'll be retired in one pass once enough of Core Settings/Addons/Advanced is migrated. Bumped SCRIPT_VERSION to 2.1.0 with matching changelog entries in the script header and Readme, and updated the Readme's "Modular Management" section to state plainly what is and isn't migrated yet. Verified: - Full regression: re-ran the Sites and Display scratch-config test suites against the updated run_menu signature - both still clean. - New scratch-config tests for hidden_pin.sh (set/mismatch/reject/ disable/reset, correct file permissions) and timezone.sh (builder entry count, common-zone pick by index, manual entry with legacy US/* alias normalization, region search + cancel, invalid-zone rejection) - all correct, with timedatectl/sudo stubbed only where needed to avoid mutating this sandbox's real system clock/timezone. - End-to-end: ran the real install.sh as a genuine non-root, non-"kiosk" user, navigating Timezone -> manual entry -> invalid zone -> confirmed no crash and a normal return to the menu, then Hidden Site PIN -> set a PIN -> confirmed the file on disk (mode 600, correct content) -> clean exit (code 0).

This does **not** yet replace first-time installation — that's still the

most of the old installer. `ubuntu-based-kiosk.sh` is still ~12,000

**Recent Updates (v2.1.0):**
|
||||
- **Two more menus migrated:** Timezone (`menus/timezone.sh`) and Hidden Site PIN (`menus/hidden_pin.sh`), joining Sites & Page Timing and Display & Interaction in `./install.sh`. Timezone also replaces the old hand-numbered 18-entry list with a data-driven one built on the generic menu framework.
|
||||
- **Bug fix (framework-level):** `install.sh` runs under `set -e`; a menu action that legitimately fails (e.g. rejecting an invalid timezone) and returns non-zero as its last statement could take down the *entire* session instead of just that action. Caught by testing before this ever shipped broadly; `run_menu()` now absorbs a failed handler's exit code, protecting every menu — present and future.
|
||||
- The old, unmigrated `configure_sites`/`configure_touch_controls`/`configure_navigation_security`/`configure_optional_features` in `ubuntu-based-kiosk.sh` are staying in place for now (still carrying the v2.0.0 bugs below) until enough of Core Settings/Addons/Advanced is migrated to retire them in one pass — see "Modular Management" below for exactly what's covered so far.
|
||||
|
||||
**Previous (v2.0.0):**
|
||||
- **Modular management path:** new `lib/menu.sh` (reusable numbered-menu framework: auto-numbered entries, `0` always exits/returns) and `lib/config.sh` (single load/save for `config.json`), with menus migrating into `menus/*.sh` one at a time — **Sites & Page Timing** and **Display & Interaction** are migrated so far. Run via `./install.sh` after cloning the repo, against an already-installed kiosk (see "Modular Management" below). Groundwork for the planned web-based GUI, which will share this same `lib/config.sh` layer.
|
||||
- **Bug fix:** the old Sites menu could save `config.json` without first loading swipe/navigation/lockout settings, silently resetting them to script defaults.
|
||||
- **Bug fix:** reordering sites had an off-by-one that left the moved site one slot short of the requested position.

# framework: the old hand-numbered 18-entry case statement is now just
|

# a data list plus one handler.

# - Hardened lib/menu.sh: since this whole tool runs under `set -e`, a menu
|
||||
# action that legitimately fails (e.g. rejecting an invalid timezone) and
|
||||
# returns non-zero as its last statement could take down the *entire*
|
||||
# session, not just that one action - one typo would silently drop the
|
||||
# user back to their shell. Caught by testing menus/timezone.sh (its
|
||||
# set_timezone() does `return 1` on an invalid zone) before this ever
|
||||
# shipped; run_menu() now absorbs a failed handler's exit code so it
|
||||
# only redraws the menu, protecting every menu, present and future.

# - The old (unmigrated) configure_sites/configure_touch_controls/
|

# configure_navigation_security/configure_optional_features functions
|
||||
# still live in this script, unchanged, and still have both v2.0.0 bugs
|
||||
# above - left in place deliberately until enough of Core Settings/
|
||||
# Addons/Advanced is migrated to retire them in one pass. configure_
|
||||
# timezone/configure_hidden_site_pin don't share the set -e hazard
|
||||
# (they never use a bare `return 1`), but are otherwise also still
|
||||
# here unchanged pending the same cleanup. See Readme.md ("Modular
|
||||
# Management") for current migration status.
