[Unreleased]

Fixed

• Printing & Ticket Saving: Fix freeze under heavy workload / long shifts (2026-06-09)

  • Four bugs combined to freeze printing and order saving on busy days or when end-of-day is not run for extended periods.
  • Bug A — thread pool blocking main event loop (src/core/thread_pool.hh): enqueue_detached() called condition_variable::wait when the job queue was full (64 jobs, 2 workers). Under heavy load with slow CUPS jobs the queue filled, and the next print call blocked the main Xt event loop thread until a worker freed a slot — freezing the UI, printing, and order saving completely. Fix: replaced the blocking wait with a non-blocking check that drops the job and logs to stderr if the queue is full. Thread count increased 2→4 and queue cap increased 64→256 so the drop condition is extremely rare in practice.
  • Bug B — CUPS health check running fork()+exec() on the main thread (src/core/data_persistence_manager.cc): CheckCUPSHealth() was called from Update() which runs on the main event loop timer every 500 ms. Every 60 seconds it forked a child to run systemctl is-active cups and busy-polled with usleep(10ms) for up to 5 seconds. On CUPS failure AttemptCUPSRecovery() added another 10-second busy-poll — all on the main thread, causing regular multi-second freezes under any CUPS instability. Fix: moved the entire CUPS health check into a dedicated CUPSMonitorLoop background thread. ProcessPeriodicTasks() on the main thread now only reads an atomic<bool>.
  • Bug C — SaveAllChecks() running synchronously on the main thread (src/core/data_persistence_manager.cc): Every 30 seconds, SaveCriticalData() → SaveAllChecks() iterated the entire open check list and wrote each check to disk (open + write + close) on the main event loop thread. On a busy shift with 100–200 open checks — or more when end-of-day is never run — this caused hundreds of sequential blocking file I/O operations per cycle. Fix: auto-save is now dispatched to the thread pool via enqueue_detached. An atomic<bool> save_in_progress_ flag prevents double-dispatch.
  • Bug D — RemotePrinter::Send() flush threshold exceeds buffer size (main/hardware/remote_printer.cc): Send() only flushed the output buffer when buffer_out->size > 4096, but buffer_out is a CharQueue(1024). The threshold was never reached, so intermediate Send() calls were no-ops. Large receipts silently overflowed the ring buffer and dropped bytes, producing garbled or truncated prints. Fix: flush threshold changed to buffer_size / 2 (512 bytes), matching the CharQueue::send_size design. Dropped jobs in CloseAsync() now call ReportError() so the operator sees a message on screen.
  • Files modified: src/core/thread_pool.hh, src/core/data_persistence_manager.hh, src/core/data_persistence_manager.cc, main/hardware/remote_printer.cc, main/hardware/printer.cc.

• Printing & Ticket Saving: Fix 10-12 hour runtime failure (2026-06-02)

  • After extended runtime (~10-12 hours) the system would silently stop printing and saving new orders. Three bugs combined to cause this.
  • Root cause — stale Xt input handler spin loop (main/hardware/remote_printer.cc): PrinterCB() was closing the socket and marking the printer offline (failure = 999) but never calling RemoveInputFn(p->input_id). The X event loop continued polling the closed file descriptor on every tick, creating an infinite error-callback spin loop. Over 10-12 hours of normal restaurant operation this CPU waste progressively starved the main event thread, causing both printing and order-saving to hang. Fix: deregister the input handler (RemoveInputFn + input_id = -1) before closing the socket in the offline-marking block.
  • Secondary — blocking system() call in LPDPrint (main/hardware/printer.cc): Printer::Close() called the synchronous LPDPrint() (which runs system("cat file | lpr -P...")) on the main thread. If CUPS became unresponsive this blocked the entire event loop for the duration. Fix: Close() now delegates TARGET_LPD and TARGET_SOCKET to CloseAsync(), which already dispatches print jobs to a background thread pool.
  • Tertiary — silent I/O errors in archive save (main/data/archive.cc, src/core/data_file.hh): Archive::SavePacked() did not check for write errors after the drawer and check write loops. A disk-full or I/O error would be silently ignored and the archive marked as successfully saved. Fix: added OutputDataFile::HasError() (using ferror/gzerror) and inserted checks after both write loops with appropriate ReportError messages and early-return on failure.
  • Files modified: main/hardware/remote_printer.cc, main/hardware/printer.cc, main/data/archive.cc, src/core/data_file.hh.

Removed

• Button Properties Dialog: Remove redundant "Menu Type" field (2026-05-28)
  • The "Menu Type" selector (item_type DialogMenu widget in ZoneDialog) was redundant with the more specific zone types already present in "Button's Type" (ZONE_ITEM_NORMAL, ZONE_ITEM_MODIFIER, ZONE_ITEM_METHOD, ZONE_ITEM_SUBSTITUTE, ZONE_ITEM_POUND, ZONE_ITEM_ADMISSION). The item classification (itype) is now derived entirely from the selected zone type; for the legacy generic ZONE_ITEM type the classification defaults to ITEM_NORMAL. The network protocol byte is preserved unchanged.
  • Files modified: term/term_dialog.hh, term/term_dialog.cc.

Added

• Index Tab Buttons: Selected visual feedback, no-op guard, page-zero block, and auto-page creation (2026-05-28)
  • IndexTabZone::State() now returns the selected state (1) whenever the terminal's current page matches the tab's jump_id. The tab for the active page is automatically rendered with its configured selected-state edge, texture, and font color (frame[1], texture[1], color[1]) — no new Terminal fields required.
  • IndexTabZone::Touch() returns SIGNAL_IGNORED when the terminal is already on the tab's target page, preventing a redundant page jump.
  • ZoneDB::Add(Page*) now rejects any page with id == 0, reporting an error. This is enforced at the single authoritative insertion point so no page with number zero can be created through any code path.
  • ZoneDB::NextAvailablePageID(int start_id, int page_size) helper added — returns the first unused page ID ≥ start_id for the given screen size.
  • When a brand-new ZONE_INDEX_TAB button is saved (via Terminal::ReadZone()), and it has no jump target yet (JUMP_NONE), a new PAGE_ITEM menu page is automatically created using the button's name, assigned the first available ID ≥ 60, and the button is set to JUMP_NORMAL pointing to that page. Editing an existing Index Tab with an already-configured jump is unaffected.
  • Files modified: zone/button_zone.hh, zone/button_zone.cc, zone/zone.hh, zone/zone.cc, main/hardware/terminal.cc.

Work In Progress

• Allow Multiple Terminal Logins (experimental) (2026-04-12)
  • Added a persisted soft-switch allow_multi_login (bumped SETTINGS_VERSION to 107) which allows the same Employee to be logged into multiple terminals when enabled.
  • Exposed a new Settings switch Allow Multiple Logins in the Settings UI (toggles and persists immediately).
  • Login logic updated so Terminal::LoginUser and login UI checks consult settings->allow_multi_login before rejecting a login for a user already online.
  • Files modified: main/data/settings.hh, main/data/settings.cc, main/ui/labels.cc, zone/settings_zone.cc, main/hardware/terminal.cc, zone/login_zone.cc.
  • NOTE: This feature is experimental and a work in progress — bugs are likely. Use with caution and report any issues you encounter.

Changed

• build.sh: Simplified terminal-only build script (2026-04-14)
  • Replaced the previous interactive/TUI build.sh with a simplified terminal-only helper that detects the distribution's package manager, installs missing build dependencies, and runs CMake configure → build → install.
  • Removed duplicate content and GUI/TUI helper code; made build.sh executable.
  • Files modified: build.sh
• Reports/UI: Add Report::TextKV/TextKVMid and refactor report/zone outputs (2026-04-14)
  • Added Report::TextKV() and Report::TextKVMid() helpers to simplify label/value printing in reports (main/ui/report.hh, main/ui/report.cc).
  • Redesigned the System::DepositReport() printed layout for clearer 80-column output and reconciliation sections (main/ui/system_report.cc).
  • Converted many simple left/right label/value callsites to use TextKV/TextKVMid (reports) or TextLR (on-screen zones) to unify alignment and reduce duplication across the UI and printed reports.
  • Fixed a misleading indentation/guarding bug in zone/inventory_zone.cc.
  • Files modified (selected): main/ui/report.hh, main/ui/report.cc, main/ui/system_report.cc, main/business/check.cc, zone/payment_zone.cc, zone/order_zone.cc, zone/inventory_zone.cc, zone/drawer_zone.cc, zone/table_zone.cc, zone/phrase_zone.cc, zone/payout_zone.cc, zone/settings_zone.cc, zone/user_edit_zone.cc.
  • Follow-up: finish the payment-entry sweep, add unit tests for Deposit/Book Balance output, and update translations.

Fixed

• Video Display: Prevent blank checks on Bar/Kitchen video (2026-04-14)

  • Fixed bug where an empty check header could be displayed on Bar/Kitchen video when orders had been removed or when new items were added but not sent.
  • ReportZone::ShowCheck() now uses Check::PrintCount(..., ORDER_SHOWN) to ensure the check contains printable (sent and not-yet-shown) items for the specific video target before selecting it for display.
  • Files modified: zone/report_zone.cc
  • Impact: Video zones will no longer show blank check headers unless there are actual printable items for that target.

• Video Display: Keep Bar and Kitchen video checks independent when served/marked done (2026-04-14)

  • Prevented marking orders for the entire check as shown when serving from a single video display.
  • Scoped ORDER_SHOWN to only orders whose Order::VideoTarget(settings) matches the active video_target (bar vs kitchen/default).
  • Modified ReportZone::ToggleCheckReport() to set ORDER_SHOWN only for matching-target orders instead of calling Check::SetOrderStatus(nullptr, ORDER_SHOWN).
  • Files modified: zone/report_zone.cc.
  • Impact: Serving/marking done on Bar video no longer removes items from Kitchen video (and vice versa). Follow-up: timer interaction when closing the other display still needs to be addressed.

• Video Display: Timers and display refresh for video check zones (2026-04-14)

  • Fixed the timer and refresh bug where elapsed-time counters would stop updating until the display was tapped.
  • Avoided setting CF_SHOWN globally in ReportZone::ToggleCheckReport() and stopped using the per-check made_time to change another target's display state.
  • Ensured the manager now sends UPDATE_BLINK to terminals whose pages contain a ReportZone configured for REPORT_CHECK with a non-default VideoTarget() or a non-zero CheckDisplayNum(), so timers refresh continuously.
  • Files modified: zone/report_zone.cc, main/data/manager.cc.
  • Impact: Kitchen and Bar video timers update continuously and independently; no manual tap required to refresh.

• Video Display: Start timers only when displayed; per-target display tracking (2026-04-14)

  • Added an in-memory per-check displayed_target_mask and Check::MarkDisplayed/Check::ClearDisplayed helpers so the kitchen/bar timer (chef_time) starts only when the check is actually shown on a given video target and is cleared when removed from all targets.
  • Removed unconditional chef_time.Set() calls from FinalizeOrders() and Close(); timer lifecycle is now driven by the display code in ReportZone.
  • Files modified: main/business/check.hh, main/business/check.cc, zone/report_zone.cc.

• Video Display: Do not show unsent items on Bar/Kitchen video (2026-04-14)

  • Fixed a bug where items added to a check while it was being displayed would appear on Bar/Kitchen video even if they had not been sent.
  • Only orders/modifiers with ORDER_SENT are now considered for video display; the video display logic and printing path were updated to respect ORDER_SENT and ORDER_SHOWN correctly.
  • Changes include updates to Order::PrintStatus, Check::PrintCount, and Check::MakeReport to ensure unsent (blue) items are not shown until explicitly sent.
  • Files modified: main/business/check.cc.

• Shutdown: Prevent Xft/Xrender crash & finalize font handling (2026-04-14)

  • Implemented coordinated shutdown to avoid races between Xt timers/inputs and X display close; added app_shutting_down flag and update_timer_mutex to serialize timer/input removal and re-arming.
  • Replaced immediate KillTerm()/exit() calls from input callbacks with a cooperative shutdown request so the event loop and callbacks can unwind safely.
  • Ensure background logging and worker threads are stopped during shutdown by calling spdlog::shutdown() in Logger::Shutdown() and shutting down the global vt::ThreadPool early in KillTerm().
  • Close Xft fonts with XftFontClose() and call FcFini() after the display has been closed to prevent Xft from calling into finalized fontconfig during XCloseDisplay.
  • Files modified: term/term_view.cc, src/utils/vt_logger.cc.
  • Impact: reduces shutdown-time SEGVs and Xft/Xlib race conditions; follow-up: audit startup XftFontOpenName usages to eliminate remaining fontconfig leaks.

• Auto-Update vt_data: Prevent automatic updates when disabled (2026-04-09)

  • Fixed unexpected vt_data downloads/updates triggered when restarting or shutting down from non-server displays even when "Auto-Update vt_data on Startup" is OFF.
  • Root Cause: early startup autoupdate script executed based on .viewtouch_config.autoupdate before the authoritative fixed settings were consulted; restart flows that use the command file + vtrestart could relaunch vt_main which ran the script regardless of the UI toggle.
  • Solution:
    • Startup autoupdate now requires both .viewtouch_config.autoupdate and the fixed settings file (/usr/viewtouch/dat/settings.dat) auto_update_vt_data flag to be true before running the update script.
    • FindVTData() now respects auto_update_vt_data and will not download vt_data when auto-update is disabled.
    • The UI switch persists immediately (settings->Save()), ensuring restarts honor the user's preference.
    • Added logging when autoupdate is suppressed and when restart origin is recorded for auditing.
  • Impact: Restarting or shutting down from any display no longer triggers automatic vt_data updates when the setting is OFF.
  • Files modified: main/data/manager.cc, zone/settings_zone.cc

• Default Employees: Only create preset employees when missing (2026-04-09)

  • Fixed issue where preset/default employees were created every startup even when employee.dat already existed.
  • Solution: Only create default/preset employees when employee.dat is missing.
  • Files modified: main/data/manager.cc

• Dialog: Fix crash when opening/using Add Comment dialog (2026-04-08)

  • Prevents a segmentation fault when opening or submitting the Add Comment dialog caused by an uninitialized key pointer in GetTextDialog.
  • GetTextDialog constructors now initialize all entries of key[] to nullptr to avoid dereferencing uninitialized pointers.
  • Files modified: zone/dialog_zone.cc

• Order Comment: Treat comment modifiers like normal modifiers (2026-04-08)

  • Comment modifiers were previously assigned a hardcoded call_order, which caused them to be moved to the bottom when new normal modifiers were added. Comments now inherit a contextual call_order so they preserve insertion order and behave like normal modifiers.
  • Files modified: zone/dialog_zone.cc

• Hardware Zone: Prevent accidental overwrites when switching selections (2026-04-08)

  • Fixed bug where editing or creating a display/printer then switching selections could overwrite a different record with empty form values.
  • Root Cause: SaveRecord() could be called for a record that had not been loaded into the form, combined with transient row→record mapping during list interactions.
  • Solution: HardwareZone now tracks which section/record the form was loaded for (loaded_section/loaded_record) and SaveRecord() skips writes unless the form was explicitly loaded for that record. Also ensured row→record mapping is rebuilt before touch handling and added diagnostics to trace load/save events.
  • Files modified: zone/hardware_zone.cc, zone/hardware_zone.hh

• Auto-Update vt_data Inconsistency Between Displays (2026-02-12)

  • Fixed bug where vt_data auto-update setting behaved differently on server display vs external displays
  • Root Cause: The auto_update_vt_data setting was loaded from the settings file in the data directory, which could be different for different displays in multi-display setups
  • Solution: Modified the auto-update check to load the setting from a fixed path (/usr/viewtouch/dat/settings.dat) to ensure consistency across all displays
  • Impact: vt_data auto-update setting now works consistently regardless of which display is used to start the system
  • Files modified: main/data/manager.cc

• Hardware Button Type: Server Terminal Duplicates and Printer Removal (2026-02-12)

  • Fixed bugs in Hardware zone that created duplicate server terminals and incorrectly removed shared printers
  • Bug 1: Duplicate Server Terminals
    • Root Cause: FindServer() assumed first terminal was always server but didn't properly search for existing servers or handle loaded settings with incorrect order
    • Solution: Rewrote FindServer() to first search for terminal matching display hostname, then existing server terminals, ensure correct terminal is marked as server and moved to front, clear IsServer flags from others, and remove duplicate "Server" named terminals
    • Impact: Server terminals are correctly identified, duplicates are prevented and cleaned up
  • Bug 2: Shared Printer Removal
    • Root Cause: When removing a terminal, associated printer was killed even if other terminals shared the same printer configuration
    • Solution: Added IsPrinterShared() method to check if printer is used by multiple terminals, modified KillRecord() to only kill printer if not shared
    • Impact: Printers are preserved when shared between terminals, only removed when truly no longer needed
  • Files modified: main/data/settings.cc, main/data/settings.hh, zone/hardware_zone.cc

• Hardware Button Type: Simplified Server Display Logic (2026-02-05)

  • Completely simplified the server display and terminal initialization logic
  • New Approach: The FIRST terminal in the list is ALWAYS the server display
  • Changes Made:
    • Rewrote FindServer() to simply return the first terminal and ensure it's marked as server
    • Simplified remote terminal initialization to skip the first terminal (server) and process others
    • Removed complex multi-pass server detection and matching logic
    • Removed have_server counting and display_host matching complexity
    • Added automatic cleanup of duplicate "Server" terminals created by previous buggy code
  • Root Cause: Previous complex logic with multiple passes, display_host matching, and server flag tracking was causing duplicate server displays to be created and persisted
  • Solution: Simple rule - first terminal = server, all others = remote displays. FindServer() now removes any duplicate auto-created "Server" terminals found after the first terminal.
  • Impact: No more duplicate server displays, existing duplicates are automatically cleaned up on startup
  • Files modified: main/data/manager.cc, main/data/settings.cc

• Hardware Button Type: Critical Startup Bugs (2026-02-04)

  • Fixed multiple critical bugs in Hardware button type that caused issues after system reboot
  • Bug 1: Printer Deletion on Every Startup
    • Root Cause: Code was migrating receipt printer from printer list to server terminal on every startup, then deleting it
    • Solution: Added check to only migrate printer if server terminal doesn't already have one configured
    • Impact: Printers no longer disappear or get replaced with defaults after reboot
  • Bug 2: Terminal Iterator Not Reset
    • Root Cause: When cleaning up multiple server terminals, the iterator wasn't reset before the second processing loop
    • Solution: Added ti = settings->TermList() to reset iterator after cleanup
    • Impact: Terminal initialization now processes all terminals correctly
  • Bug 3: Multiple Terminals Marked as Server
    • Root Cause: have_server count wasn't updated after marking a terminal as server, allowing multiple terminals to be set as server in single startup
    • Solution: Added have_server = 1 after each IsServer(1) call
    • Impact: Only one terminal is now marked as server
  • Bug 4: FindServer Priority Issue
    • Root Cause: FindServer() checked display_host match before IsServer flag, potentially returning wrong terminal
    • Solution: Changed to two-pass approach - first find explicit server, then check display_host match
    • Impact: Existing server terminal is always found first
  • Files modified: main/data/manager.cc, main/data/settings.cc

• Tender Settings Button Type: Null Pointer and Record Navigation Bugs (2026-02-04)

  • Fixed bugs in TenderSetZone::KillRecord that could cause crashes and navigation issues
  • Changes Made:
    • Added null pointer checks before accessing record data in all sections (Discounts, Coupons, Credit Cards, Comps, Employee Meals)
    • Added consistent display_id and record_no handling for all sections (previously only Discounts had this)
  • Root Cause: KillRecord didn't check if FindXxxByRecord() returned nullptr before dereferencing, and sections 1-4 didn't update navigation state after deletion
  • Solution: Added null checks and consistent record navigation handling across all tender types
  • Files modified: zone/settings_zone.cc

Added

• 🚀 Recommendations for Modern POS Transformation (2026-01-24)

      • Remaining: 14 sprintf/snprintf calls in 5 files (mostly comments/includes)
      • Priority files: main/hardware/printer.cc (1 call) - COMPLETED
      • Recommendation: Use the existing modernize_cpp23.sh to systematically convert remaining sprintf/snprintf calls to format_to_buffer().
    • 1.2 Expand Test Coverage
      • Current: 14 test files, ~671 assertions
      • Target areas: Payment processing (credit.cc, check.cc), Data serialization/deserialization, Hardware interface mocking, UI zone logic
  • Root Cause: Ongoing modernization effort to improve code safety, maintainability, and test coverage
  • Solution: Systematic completion of C++23 migration and test expansion
  • Impact: Enhanced code quality, security, and reliability for production deployment

• Split Check Interface: Complete Redesign for Simplicity and Functionality (2026-01-20)

    • Improved empty state messaging for better user guidance
    • Enhanced instruction text for clearer user direction
    • Removed complex text wrapping and formatting for cleaner, simpler display
  • Root Cause: Original split check interface was overly complex with cluttered displays, poor visual hierarchy, and confusing user experience
  • Solution:
    • Simplified ItemObj::Render to use basic text display without wrapping
    • Streamlined CheckObj::Render to show essential information only
    • Added conditional tax display with proper positioning
    • Changed selected item texture to IMAGE_YELLOW_TEXTURE for clear visual feedback
    • Repositioned total amounts to avoid overlaying UI edges

    • zone/split_check_zone.cc (main interface implementation)
    • zone/split_check_zone.hh (header declarations)
    • main/business/check.cc (added SplitCheckEqually method, later removed)
    • main/business/check.hh (SplitCheckEqually declaration, later removed)
  • Impact: Split check interface now provides clean, simple, and functional experience with clear visual feedback, proper pricing display, and intuitive manual item selection

• Out of Stock (86) Toggle Feature for Menu Items (2026-01-31)

  • Added ability to mark menu items as "86" (out of stock) with visual feedback on buttons
  • Changes Made:
    • Added out_of_stock boolean field to SalesItem class for tracking availability
    • Updated data file version to 17 for backward compatibility
    • Modified ItemZone rendering to display "Item Name - Out of stock" in red when item is unavailable
    • Added "Out of Stock (86'd)?" toggle in item editing interface
    • Implemented safe color override during rendering to maintain visual consistency
  • Root Cause: No built-in way to temporarily disable menu items without removing them entirely
  • Solution: Added toggleable out-of-stock status with clear visual indicators
  • Files modified:
    • main/business/sales.hh (added out_of_stock field)
    • main/business/sales.cc (updated serialization and data handling)
    • zone/inventory_zone.cc (added editing interface)
    • zone/order_zone.cc (modified rendering logic)
  • Impact: Staff can now easily identify unavailable items, managers can quickly toggle item availability, improves operational efficiency during stock shortages

• Fixed Order Entry Total Off-by-One-Cent Issue with Tax (2026-01-31)

  • Resolved discrepancy between Order Entry zone total display and actual check total when tax is included
  • Changes Made:
    • Modified OrderEntryZone::Render to use pre-calculated tax totals from SubCheck instead of recalculating tax per individual order
    • Replaced per-order tax summation with direct use of aggregated tax fields (total_tax_food, total_tax_GST, etc.)
  • Root Cause: Order Entry zone was calculating tax by summing individual order taxes, while check totals use aggregated tax calculation, causing rounding differences
  • Solution: Use the same tax calculation method as the main check total for consistency
  • Files modified: zone/order_zone.cc (OrderEntryZone::Render method)
  • Impact: Order Entry zone now displays the exact same total as the final check, eliminating confusion for staff

Fixed

• Fixed GCC 14 Warning in Date Library (2026-01-25)

  • Resolved stringop-overflow warning in external/date/include/date/date.h when compiling on Raspberry Pi Compute Module 5 with GCC 14
  • Changes Made:
    • Changed buffer size calculation from std::numeric_limits::digits10+2u to std::numeric_limits::digits10+2u
    • Updated cast from static_cast(a0) to static_cast(a0)
  • Root Cause: GCC 14's enhanced bounds checking detected potential out-of-bounds access in the read function's buffer
  • Solution: Used unsigned long long type for safer buffer sizing
  • Files modified: external/date/include/date/date.h
  • Impact: Eliminates compiler warning without changing functionality

• Removed Automatic Creation of System Page -94 (2026-01-23)

  • Eliminated the automatic creation of page -94 (Index with Tabs template) that was causing "Can't delete page -94" errors
  • Changes Made:
    • Removed the code that creates page -94 for all screen resolutions during ZoneDB initialization
    • Simplified page 60 creation to use a default template instead of copying from page -94
  • Root Cause: System was automatically creating page -94 as a template for Index with Tabs pages, but this page couldn't be deleted, causing user confusion and errors
  • Solution:
    • Removed the template creation loop in ZoneDB::Init()
    • Modified page 60 creation to always use a basic default configuration
  • Files modified:
    • zone/zone.cc (removed page -94 creation code and simplified page 60 creation)
  • Impact: Prevents "Can't delete page -94" errors and reduces system complexity by removing unnecessary template pages
  • Improved the split check zone interface for better readability and user experience
  • Changes Made:
    • Added dynamic font responsiveness - buttons now properly inherit font sizes from zone settings
    • Implemented text wrapping instead of truncation - long item names now wrap to multiple lines within buttons
    • Increased button widths - order item buttons from 250px to 280px, seat buttons from 120px to 150px
    • Doubled button heights - order buttons from 40px to 80px, seat buttons from 84px to 168px
    • Removed modifier display from split check buttons for cleaner interface
  • Root Cause: Split check buttons had hardcoded fonts, truncated text, cramped dimensions, and cluttered display with modifiers
  • Solution:
    • Modified ItemObj constructors to accept font_id parameters and use dynamic fonts
    • Added RenderWrappedText helper method for word-based text wrapping
    • Increased button dimensions for better text accommodation
    • Removed modifier rendering loop and dynamic height calculation
  • Files modified:
    • zone/split_check_zone.cc (main implementation)
    • zone/split_check_zone.hh (method declaration)
  • Impact: Split check interface now displays longer item names clearly with proper text wrapping, responsive fonts, and improved button sizing for better usability

    • Incorrect calloc argument order in memory allocation
    • Misleading indentation in settings zone
    • False-positive null dereference warnings
    • Third-party dangling reference warnings from spdlog

Recent Maintenance (2026-04-13)

• Security & Robustness: Replaced unsafe shell usage across the codebase

  • Replaced uses of system(), popen(), and execl("/bin/sh", "sh", "-c", ...) patterns with safer APIs or exec-based helpers and proper argument lists.
  • Major changes include: src/core/data_persistence_manager.cc, src/core/crash_report.cc, src/utils/utility.cc, term/term_view.cc, and multiple helper scripts under scripts/.
  • Vendor patch: external/date/src/tz.cpp was updated to use std::filesystem for file/directory operations and execv/createprocess-based helpers for archive extraction instead of std::system().

• Build / CI: enabled unit tests in CI and ran ctest locally

  • GitHub Actions workflow updated to configure CMake with -DBUILD_TESTING=ON and run ctest after build.
  • Local Debug build and unit tests executed successfully: 83/83 tests passed (2026-04-13).

• CMake Modernization: moved a subset of global include directories to target-scoped includes

  • Converted global include_directories(...) usage to target_include_directories(...) for vtcore and image_data to improve dependency visibility and catch missing includes earlier.

• Scripts: audited and hardened Perl/shell scripts to avoid shell interpolation and unsafe backticks

  • Replaced backticks and string-interpolated system() calls with list-form system or safe file I/O where appropriate (examples: scripts/tools/update-client, scripts/tools/dat2txt, scripts/system/vtrun).

These changes were committed on a feature branch for review. See the PR for detailed diffs and rationale.

• Changes Made:

  • Changed label from "Kitchen Video Print Method" to "Remote Video"
  • Updated option names from "Unmatched"/"Matched" to "Split Checks"/"Consolidate Checks"
  • Updated all locale translations (English and Spanish)

• Root Cause: The original terminology was unclear and not intuitive for users

• Solution: Replaced with more descriptive and user-friendly terminology that better reflects the functionality

• Files modified:

  • zone/settings_zone.cc (main UI label)
  • main/ui/labels.cc (option names)
  • main/data/locale.cc (internationalization support)

• Impact: Receipt Settings page now has clearer, more intuitive labeling that better communicates the split/consolidate check functionality to users

• Build Warnings: Comprehensive Warning Cleanup (2026-01-20)

  • Fixed multiple compiler warnings across the codebase to improve code quality and reduce noise
  • Issues Fixed:
    • Header guard mismatches in network and core header files
    • Buffer overflow in GetTermWord() string parsing function
    • Potential null pointer dereference in WorkReceipt() labor reporting
    • Uninitialized variables in terminal record file reading
    • Missing null checks in form field loading
    • Uninitialized pointer in list sorting algorithm
    • Missing virtual keyword in function override
  • Root Cause: Various code quality issues accumulated over time, including unsafe string operations, missing initialization, and inconsistent header guards
  • Solution:
    • Corrected header guard definitions to match standard naming conventions
    • Fixed string parsing to prevent buffer overflows by limiting copy operations
    • Added null pointer checks and variable initialization where needed
    • Added virtual keyword to properly override base class methods
  • Files modified:
    • src/network/remote_link.hh, src/core/debug.hh, src/core/image_data.hh (header guards)
    • main/data/manager.cc (buffer overflow fix)
    • main/business/labor.cc (null check)
    • main/hardware/terminal.cc (uninitialized variables)
    • zone/merchant_zone.cc (null checks)
    • src/core/list_utility.hh (pointer initialization)
    • term/term_view.cc (virtual function)
  • Impact: Reduced build warnings from ~814 to ~240 in our codebase, improved code safety and maintainability

• UI: Add Dollar Signs to Guest Check and Payment Summary Amounts (2026-01-15)

  • Fixed missing dollar signs ($) on amounts displayed in Payment Summary window and Guest Check Window menu items
  • Root Cause: Terminal::FormatPrice() has a default parameter sign = 0 which excludes the currency symbol, and many calls used this default instead of explicitly setting sign = 1
  • Solution: Changed all FormatPrice() calls in check display functions to use sign = 1 to include dollar signs on all amounts (individual items, modifiers, taxes, payments, and totals)
  • Files modified: main/business/check.cc (MakeReport function and related price display calls)
  • Impact: Guest Check Window and Payment Summary now consistently display all amounts with proper currency formatting including dollar signs

• Settlement Page: Highlight Current Guest Check with Status (2026-01-15)

  • Added highlighting and status display for current guest check when multiple checks exist on settlement page
  • Changes Made:
    • Changed subcheck display from "#1" to "Check #1 - Open/Closed/Voided"
    • Added background highlighting for the currently selected subcheck
    • Used blue text color for better visibility when highlighted
  • Files modified: zone/payment_zone.cc (header rendering in Render function)
  • Impact: Users can now clearly see which guest check is currently selected on the settlement page, with status information and visual highlighting

• Payment Zone: Hide Zero VAT Display (2026-01-15)

  • Fixed VAT .00 being displayed unnecessarily when VAT amount is zero
  • Root Cause: VAT display only checked if VAT tax rate was configured (settings->tax_VAT > 0) but not if the calculated VAT amount was actually greater than zero
  • Solution: Added condition to check both settings->tax_VAT > 0 AND subCheck->total_tax_VAT != 0
  • Files modified: zone/payment_zone.cc (VAT display logic in Render function)
  • Impact: VAT is now only displayed when there is an actual VAT amount to show, reducing UI clutter

• Printer: Prevent USB Printer Hanging (2026-01-15)

  • Fixed application hanging when USB printer is unavailable
  • Root Cause: open() system call for printer device files would block indefinitely when USB printer was disconnected or unavailable
  • Solution: Added O_NONBLOCK flag to printer device open call to prevent blocking
  • Files modified: main/hardware/printer.cc (ParallelPrint function)
  • Impact: Application continues to function normally even when USB printers are unavailable, preventing system hangs

• Per-Terminal Button Image Settings: Preserve Individual Terminal Preferences (2026-01-15)

  • Fixed global "Show Button Images" setting incorrectly overriding per-terminal customizations
  • Root Cause: The global setting was being applied universally, ignoring individual terminal configurations
  • Solution: Added show_button_images_custom flag to Terminal class to track when users have customized per-terminal settings, preserving their preferences when global setting changes
  • Files modified: main/hardware/terminal.cc, main/hardware/terminal.hh
  • Impact: Terminals now maintain their individual button image display preferences even when global settings are modified

• Button Highlighting Bug - Remove Broken Static Cache (2026-01-10)

  • Fixed buttons incorrectly showing highlighted/yellow state
  • Root Cause: The static tile cache optimization in Layer::Rectangle() was fundamentally broken. Static variables persisted across all calls, causing stale cache values to be used when rendering buttons with different textures.
  • Solution: Removed the static cache optimization entirely. Each Rectangle() call now properly sets the tile and origin, ensuring correct texture rendering.
  • Files modified: term/layer.cc

• C++23 Feature Detection: Fix std::expected Compilation on Older Compilers (2026-01-18)

  • Fixed compilation errors on systems with older compilers that don't support std::expected
  • Root Cause: The feature detection used __has_include(<expected>) which only checks for header presence, not actual implementation availability in the standard library
  • Solution: Changed to use __cpp_lib_expected feature test macro for proper detection of std::expected support
  • Files modified: src/utils/cpp23_utils.hh
  • Impact: Allows building on Raspberry Pi and other systems with older compilers that lack C++23 std::expected support

• Button Highlighting Bug with Lazy Texture Loading (2026-01-09)

  • Fixed buttons incorrectly showing highlighted state when they shouldn't be
  • Root Cause: The lazy texture loading introduced in the memory optimization commit conflicted with the static tile cache in Layer::Rectangle(). When textures were loaded on-demand, the cache could cause incorrect texture rendering.
  • Solution: Added PreloadAllTextures() function that loads all textures at startup, ensuring consistent Pixmap values before any rendering occurs.
  • Files modified: term/term_view.cc, term/term_view.hh

• Terminal Crash: Prevent X11 BadMatch Errors from Oversized Pages (2026-01-24)

  • Fixed SIGABRT crashes when server sends page sizes larger than terminal window dimensions
  • Root Cause: Server could send TERM_BLANKPAGE commands with page dimensions exceeding the terminal's allocated pixmap size, causing X11 drawing operations to fail with BadMatch errors
  • Solution: Added page size clipping in Layer::BlankPage() to ensure page dimensions never exceed the layer's actual width and height
  • Files modified: term/layer.cc
  • Impact: Prevents terminal crashes when connecting to servers with larger display configurations, ensuring stable operation across different screen sizes

• Tax Settings: Improved Decimal Display Formatting (2026-01-30)

  • Fixed tax rate display to show clean decimal formatting without trailing zeros and hide zero rates
  • Changes Made:
    • Modified TaxSettingsZone::LoadRecord() to use FormatMultiplierDisplay() for proper decimal formatting
    • Tax rates now display as "8.3" instead of "8.300000", "8.25" stays "8.25", and 0% shows as blank field
    • Used existing FormatMultiplierDisplay function to trim trailing zeros appropriately
  • Root Cause: Tax percentage fields were displaying unnecessary trailing zeros and showing "0.000000" for zero rates
  • Solution: Applied FormatMultiplierDisplay() function to format tax rates with appropriate precision and set empty strings for zero values
  • Files modified: zone/settings_zone.cc
  • Impact: Tax Settings interface now displays rates cleanly without visual clutter from extra zeros

  • Completely redesigned the numeric keypad for item quantity entry with a modern phone-style layout (1-2-3 on top row, 4-5-6 middle, etc.)
  • Removed the arbitrary 5-item limit; now allows unlimited increments up to 10,000 with a single button press
  • Enhanced entry field: larger size (200x50), bigger font (34pt), centered at top of dialog
  • Eliminated input delay by making redraws immediate (0ms instead of 500ms)
  • Removed dialog title to reduce clutter; entry field starts blank for clean quantity input
  • Files modified: zone/order_zone.cc, zone/dialog_zone.cc

• Performance: Optimized Screen Saver Drawing Efficiency (2026-01-14)

  • Significantly improved screen saver performance by reducing unnecessary drawing operations
  • Optimizations Implemented:
    • Cached font and text metrics (width/height) in static variables to avoid recomputation every frame
    • Eliminated full-screen black fill on every animation frame; now only fills screen initially and on reset
    • Added selective erasure: draws black rectangle only over previous text position before drawing new position
  • Performance Impact: Reduced CPU/GPU load during screen saver animation, especially beneficial for larger displays
  • Files modified: term/term_view.cc (DrawScreenSaver function)

Fixed

• User Edit Zone: Fix NULL and Dangling Pointer Issues in Employee Save Operations (2026-01-07)
  • Fixed critical segmentation fault (SIGSEGV) when saving employee records in User Edit button type
  • Root Causes Identified:
    1. SaveRecord() called with NULL/dangling user pointer when toggling Active/Inactive views
    2. SaveRecord() called with invalid user pointer during job filter updates
    3. Loop in SaveRecord() was advancing field pointer without null checks causing crashes on incomplete forms
  • Solutions Implemented:
    • Added user != nullptr validation before calling SaveRecord() in Signal() (active/inactive toggle)
    • Added user != nullptr validation before calling SaveRecord() in Update() (job filter changes)
    • Enhanced SaveRecord() field iteration loop with proper null checks and early breaks

• Form Zone: Fix Double-Touch and Click Area Issues in ListField (2026-01-03)

  • Fixed double-triggering of field Touch events when using touchscreen input
  • Fixed ListField click detection area not matching the visual button boundaries
  • Root Cause: Both Touch and Mouse events were calling FormZone::Touch() which triggered field actions, causing double-clicks on touchscreens
  • Solution: Changed ListFormZone::Touch() and ListFormZone::Mouse() to call LayoutZone::Touch() instead, which only updates coordinates without triggering field actions
  • Offset Fix: Changed ListField offset calculation from label_width + .6 to label_width + 1 and boundary from entry_width + 1 to entry_width to match the Render and Mouse methods
  • Files modified: zone/form_zone.cc (ListFormZone::Touch(), ListFormZone::Mouse(), ListField::Touch())
  • Impact: Tender Settings and all form zones with list fields now respond correctly to single clicks/taps without double-triggering, and buttons are clickable across their entire visual area

• CI: Update Linux Builds to C++23 Standard (2026-01-01)

  • Changed CI workflow from C++20 to C++23 to match project requirements
  • Restricted CI testing to GCC 14+ which has full C++23 stdlib support
  • Older compilers (GCC 12-13, Clang 16-18) lack std::format in libstdc++ even with -std=c++23
  • Changed std::format availability check from compile error to warning for better diagnostics
  • Project now requires C++23 for std::format and other modernization features
  • Files modified: .github/workflows/linux-simple-builds.yml, src/utils/cpp23_utils.hh
  • Impact: CI builds now use correct C++23 standard with compatible compilers matching local development

  • Added fallback implementation for std::to_underlying() when C++23 stdlib feature isn't available
  • Conditionally compile std::expected types only when available (not currently used in codebase)
  • Added compile-time error if std::format is not available (requires C++20+ with proper stdlib support)
  • Root Cause: Clang 18 with libstdc++ from GCC 14 doesn't provide all C++20/C++23 stdlib features yet
  • Files modified: src/utils/cpp23_utils.hh
  • Impact: Builds now succeed with both GCC 14 and Clang 18 when stdlib provides std::format; clear error message otherwise

• Page Inheritance: Remove Default Case Breaking Parent Page Relationships (2026-01-01)

  • Removed erroneous default: case in Page::Init() switch statement that was forcing parent_id = 0 for unhandled page types
  • This was breaking inheritance for several page types: PAGE_SYSTEM, PAGE_TEMPLATE, PAGE_CHECKS, PAGE_KITCHEN_VID, PAGE_KITCHEN_VID2, PAGE_BAR1, PAGE_BAR2
  • Restored master branch behavior where unhandled page types retain their initialized parent_id value
  • Root Cause: C++23 modernization added defensive default case without realizing some page types intentionally fall through
  • Files modified: zone/zone.cc (Page::Init function)
  • Impact: All pages now correctly inherit zones from their parent pages; matches master branch behavior exactly

Changed

Fixed

• Sales Item List button view separation (2025-12-26)

  • Fixed bug where Sales Item List button type was showing both the list of items and the selected item's configuration simultaneously
  • Root Cause: ListFormZone::Render() was unconditionally calling FormZone::Render() which displayed form fields even when showing the list view
  • Solution: Modified ListFormZone::Render() to conditionally call FormZone::Render() only when show_list is false (form view), and modified ListFormZone::Touch() to not load form fields when selecting items from the list
  • Result: List view now shows only items; form view shows only configuration fields; switching between views requires explicit "change view" signal
  • Files modified: zone/form_zone.cc (ListFormZone::Render(), ListFormZone::Touch(), ListFormZone::Signal())
  • Impact: Affects all ListFormZone-based zones (ItemListZone, etc.); behavior now matches HardwareZone pattern

• Job Security button double-touch regression (2025-12-23)

  • Prevented duplicate touch handling that immediately reverted job activation/deactivation in Job Security settings

• Hardware button list/form separation (2025-12-23)

  • Hardware view now shows only the device list by default and switches to configuration view only after an explicit "change view" signal

• Static Analysis Cleanups (2025-12-23)

  • Addressed clang-tidy findings: removed branch-clone in DList merge, added self-assignment guard to Str, corrected rounding and narrowing in test_check, fixed archive header error handling, and cleaned crash reporting/tests for empty-catch/pointer warnings
  • Suppressed analyzer padding noise for large Settings/Terminal classes and tightened enum underlying types in terminal hardware definitions
  • Impact: No behavior change; builds/tests remain green (40/40)

• Duplicate Branch Cleanup in settings.cc (2025-12-23)

  • Consolidated repeated branch bodies flagged by clang-tidy (bugprone-branch-clone)
  • CouponInfo::Applies methods: Merged duplicate retval = 0 assignments by combining conditions with logical OR
  • CouponInfo::AppliesItem: Unified duplicate return value assignments by grouping related conditions
  • Count methods (DiscountCount, CouponCount, CreditCardCount, CompCount, MealCount): Replaced four-way if-else chains with single compound conditions
    • Pattern changed from: if (A && B) count++; else if (A && C) count++; ...
    • To: if ((A || D) && (B || C)) count++;
  • Authorize method validation: Combined duplicate authorize_method = CCAUTH_NONE assignments
  • Files modified: main/data/settings.cc

      • Added bounds checking: static_cast<short>(std::min(atoi(value), 32767))
      • Prevents overflow when order quantities exceed short range
    • Socket read conversion (manager.cc line 3264): Fixed ssize_t→int narrowing for read() return
      • Changed to: ssize_t read_result = read(...); bytes_read = static_cast<int>(std::min(read_result, static_cast<ssize_t>(INT_MAX)))
      • Prevents data loss when read returns values larger than INT_MAX
  • Files modified: src/utils/fntrace.hh, main/data/manager.cc
  • Impact: Improved error visibility and prevented potential data corruption from type conversions

• Logging System Test Failure (2025-12-23)

  • Fixed persistent "Log File Output" test failure to achieve 40/40 passing tests
  • Root cause: Test directory /tmp/viewtouch_test_logs was shared across all tests, causing log accumulation and initialization conflicts
  • Solution:
    • Modified "Log File Output" test to use dedicated directory /tmp/viewtouch_test_logs_file_output
    • Fixed structured logger initialization to support both async (production) and synchronous (test) modes
    • Added per-SECTION shutdown calls to properly reinitialize logger between test sections
    • Changed spdlog::shutdown() to spdlog::drop_all() in Shutdown() to allow logger reinitialization within the same process
    • Set JSON sink pattern to "%v" instead of empty string to ensure JSON output is written
    • Changed structured log file from truncate to append mode to preserve test output
  • Files modified:
    • src/utils/vt_logger.cc:
      • Created separate structured_logger_ for JSON-only output
      • Initialize both main and structured loggers with proper async/sync configuration based on test mode
      • Enhanced Flush() to flush both logger instances
      • Replaced spdlog::shutdown() with spdlog::drop_all() for proper cleanup
    • tests/unit/test_enhanced_logging.cc:
      • Use unique test directory to isolate test from other logging tests
      • Added #include <iostream> for debug output (later removed)
      • Call Shutdown() at end of each SECTION to enable proper reinitialization
  • Impact: All 40 tests now pass consistently; logging system properly writes structured JSON and human-readable logs to separate files

  • Made email iteration state per-instance (no shared statics), preventing cross-email corruption and allowing clean restarts.
  • Files modified:
    • main/hardware/terminal.cc
    • main/business/inventory.cc
    • src/network/socket.hh
    • src/network/socket.cc

• Dialog menu buffer overflow and shutdown stability (12-05-2025)

  • Issue: Dialog menus used CompareList(int) with a non-sentinel list, overrunning the value buffer and crashing in DialogMenu::Set. Shutdown could segfault removing Xt timeouts after the app context was destroyed. Item name array used calloc but was freed with delete[], triggering allocator mismatches under ASan.
  • Fix: Bounded iteration over dialog value lists, guarded XtRemoveTimeOut when the Xt context is gone, and aligned ItemDB name array allocation/deallocation to new[]/delete[].
  • Files modified:
    • term/term_dialog.cc
    • term/term_view.cc
    • main/business/sales.cc

• Event loop stall logging (12-04-2025)

  • Issue: ViewTouch could freeze/lock up after long runtimes with no clear trace.
  • Fix: Added watchdog logging in UpdateSystemCB to report when the main loop stalls (>3s gap) to aid diagnosis of future lockups.
  • Impact: Provides actionable logs to trace intermittent freezes without changing runtime behavior.
  • Files modified: main/data/manager.cc

• CUPS/remote printer auto-recovery (12-04-2025)

  • Issue: After idle periods, printing could hang due to lost CUPS/remote printer connections, requiring full app restart.
  • Fix: Added a reconnect hook to Printer and wired RemotePrinter to perform timed, non-blocking reconnection attempts when marked offline; the main loop now triggers reconnection during periodic printer health checks.
  • Impact: Remote printers can recover automatically without restarting ViewTouch when CUPS/socket links drop.
  • Files modified:
    • main/hardware/printer.hh
    • main/hardware/remote_printer.cc
    • main/data/manager.cc

• End-of-day comment cleanup (12-04-2025)

    • src/core/error_handler.cc
    • main/hardware/terminal.hh

• End-of-day stability guard (12-04-2025)

  • Issue: End-of-day flow could dereference null terminals/system data, crashing the app when End Day was triggered.
  • Fix: Added null checks in RunEndDay and Terminal::EndDay before accessing system/settings, logging and aborting gracefully if unavailable; propagate System::EndDay failures to logs.
  • Impact: End-of-day requests no longer terminate the program if core pointers are missing; errors are logged instead.
  • Files modified:
    • main/data/manager.cc
    • main/hardware/terminal.cc

• Index Page Lookup Bug (12-XX-2025)

  • Issue: System was looking for Index page on hardcoded page 200 instead of using the proper Index page lookup mechanism
  • Root Cause: Terminal::JumpToIndex() function contained a problematic code block that jumped to hardcoded pages 200/206 based on check entree count, preventing the proper Index page lookup from executing
  • Fix: Removed the problematic code block that was jumping to hardcoded page numbers. The function now properly uses FindByType(PAGE_INDEX, idx, size) to find the correct Index page based on the index type parameter
  • Impact: After logging on and ordering, the system now correctly finds the Index page (e.g., page 60) instead of looking for non-existent page 200. Index page navigation now works correctly for all meal periods and index types
  • Files modified:
    • main/hardware/terminal.cc - Removed hardcoded page jump logic from JumpToIndex() function

• Security and Code Quality Fixes from clang-tidy Analysis (12-02-2025)

  • Impact: CI builds now complete successfully. Systemd service files will still be installed during local builds with sudo make install, but are skipped during CI builds to avoid permission errors.
  • Files modified: CMakeLists.txt

• Critical Crash Fixes: Memory Corruption and Infinite Recursion (2025-12-XX)

  • Issues: Multiple critical crashes identified through GDB debugging:
    • Terminal::Signal() crashing with invalid this pointer (use-after-free)
    • Infinite recursion in Terminal::Signal() causing stack overflow (5000+ frames)
    • Memory corruption in atomic variables (BT_Track, BT_Depth) causing crashes
    • NULL pointer dereferences in RInt8(), ReadZone(), and signal processing

  • Files modified: main/hardware/terminal.cc, main/business/labor.cc, src/core/data_persistence_manager.cc

• System Crash During EndDay (2025-12-XX)

  • Issue: System crashed when ending the day
  • Root Causes:
    • ExtractOpenCheck() could return NULL when there were no open subchecks, but the code was adding it to a list without checking, causing a NULL pointer crash
    • Empty Customer user checks (from self-order functionality) weren't being cleaned up before EndDay, potentially causing issues during archiving
  • Fix:
    • Added NULL check before adding checks to temporary list in EndDay() - only adds valid checks returned from ExtractOpenCheck()
    • Added cleanup logic to delete empty Customer user checks before EndDay, similar to how training checks are deleted
    • Empty Customer checks are now properly destroyed before archiving process begins
  • Impact: EndDay now completes successfully without crashing. Empty self-order checks are properly cleaned up, and NULL pointer crashes are prevented
  • Files modified: main/data/system.cc

    • GetSettings() could return NULL, and accessing settings->delay_time1 would crash
    • Corrupted labor database entries after a crash could return invalid job values that caused crashes when used
    • Corrupted WorkEntry linked lists could cause infinite loops or crashes when iterating through work entries
  • Fix:
    • Added NULL check for GetSettings() in LoginUser() before accessing settings members
    • Added validation for job values (0-999 range) in LoginUser() - invalid job values are reset to 0 to prevent crashes
    • Added iteration limit (10,000) in CurrentWorkEntry() to prevent infinite loops from corrupted linked lists
    • Added validation in CurrentJob() to ensure job values are reasonable before returning them
  • Impact: System now handles corrupted labor data gracefully after crashes. Users can log in safely even if labor database is corrupted. Prevents infinite loops and NULL pointer crashes
  • Files modified: main/hardware/terminal.cc, main/business/labor.cc

• Unintended Self-Order Check Creation (2025-12-XX)

  • Issue: Self-order checks were being created automatically even when not using self-order functionality:
    • Checks were created on terminal startup for SelfOrder terminals
    • Checks were created when non-customer users logged out from SelfOrder terminals
    • Checks were created when tapping buttons with "quickdinein" or "quicktogo" messages on regular terminals or non-self-order pages
  • Root Causes:
    • QuickMode(CHECK_SELFORDER) was called automatically on terminal startup
    • QuickMode(CHECK_SELFORDER) was called automatically on logout for SelfOrder terminals
    • QuickMode() had no validation to prevent self-order check creation outside of self-order mode
  • Fix:
    • Removed automatic QuickMode() call from terminal startup - checks are now only created when customers tap ordering buttons
    • Removed automatic QuickMode() call from LogoutUser() - terminal re-logs in as Customer but doesn't create a check
    • Added validation in QuickMode() to only allow self-order checks (CHECK_SELFORDER, CHECK_SELFDINEIN, CHECK_SELFTAKEOUT) when:
      • Terminal type is TERMINAL_SELFORDER, OR
      • Current page is page -2 (PAGEID_LOGIN2, the self-order page)
    • Modified QuickMode() to reuse existing open checks instead of always creating new ones
  • Impact: Self-order checks are now only created when customers actually start ordering via button presses, preventing accumulation of empty checks. Buttons like "quickdinein" and "quicktogo" no longer create checks on regular terminals or non-self-order pages

• New Items Not Appearing on Video Targets After Check Served (2025-12-XX)

  • Issue: When a check was sent to a video target, tapped twice (marked as served), and then new items were added to the same check, the new items did not appear on the video target
  • Root Cause: When a check was marked as served (CF_KITCHEN_SERVED or CF_BAR_SERVED), IsKitchenCheck() would return 0, hiding the check entirely. Even though new items were added, the check remained hidden because the served flag was still set
  • Fix:
    • Modified IsKitchenCheck() in ReportZone to detect new items (orders without ORDER_SHOWN and without ORDER_MADE that match the video target)
    • When new items are detected, automatically clear the served flag (CF_KITCHEN_SERVED or CF_BAR_SERVED) and CF_SHOWN so the check appears again
    • Modified PrintWorkOrder() and MakeReport() to only clear ORDER_SHOWN from new items (not already-made items), ensuring already-made items remain hidden
    • Logic ensures that only new items are displayed, while items that were already made and served remain hidden
  • Impact: New items added to a served check now correctly appear on their respective video targets, while already-made items remain hidden. This allows kitchen/bar staff to see only the new work that needs to be done
  • Files modified: zone/report_zone.cc, main/business/check.cc

• Kitchen Video Alert System (2025-12-XX)

  • Issue: Alerts (warn/alert/flash color changes) were not working on kitchen video displays
  • Root Causes:
    • Alert logic was only implemented in MakeReport() but not in PrintWorkOrder(), which is used when kv_print_method != KV_PRINT_UNMATCHED
    • chef_time was not being set when checks were displayed on kitchen video via PrintWorkOrder(), preventing elapsed time calculation
  • Fix:
    • Added alert logic to PrintWorkOrder() to match the implementation in MakeReport()
    • Added chef_time initialization in PrintWorkOrder() when displaying kitchen video (similar to MakeReport())
    • Alert condition ensures alerts only work for:
      • Report buttons with Button Type "Report" and Report Type "Check"
      • Report zones with a specific Video Target (not PRINTER_DEFAULT)
      • Orders that have a matching video target (not PRINTER_DEFAULT or PRINTER_NONE)
      • Checks with chef_time set (for elapsed time calculation)
  • Impact: Kitchen video alerts now work correctly for both MakeReport() and PrintWorkOrder() code paths, providing visual feedback (warn → alert → flash) based on order age
  • Files modified: main/business/check.cc

• Video Target Timer and Display Issues (2025-11-26)

  • Issue 1 - Timer Starting Incorrectly: When users added items that don't go to video targets (kitchens/bars), the timer would start. Then when items going to video targets were added later, those displays would see incorrect elapsed time
  • Root Cause 1: chef_time (the timer start time) was set whenever orders were finalized or the check was closed, regardless of whether any orders were actually destined for video targets
  • Fix 1:
    • Added HasVideoTargetOrders() method to check if a check has any orders going to video targets (not PRINTER_DEFAULT or PRINTER_NONE)
    • Modified FinalizeOrders() and Close() to only set chef_time when there are orders that actually go to video targets
    • This ensures the timer only starts when items destined for kitchens/bars are sent, not when non-video items (like retail) are sent
  • Issue 2 - Already-Made Items Reappearing: When a check was tapped twice (marked as served) and then new items were added, ALL items (including already-made ones) would reappear
  • Root Cause 2: In MakeReport(), the display logic didn't check the ORDER_SHOWN flag before displaying orders on video targets. The system uses ORDER_SHOWN to track which orders have been displayed and should not be shown again (unless they're new orders)
  • Fix 2:
    • Added ORDER_SHOWN flag checks in MakeReport() for both orders and modifiers
    • When displaying on video targets, now skips orders/modifiers that have ORDER_SHOWN flag set
    • This ensures only new items (without ORDER_SHOWN) are displayed when a check reappears
    • Note: PrintWorkOrder() already had this logic via PrintStatus(), but MakeReport() was missing it
  • Impact: Kitchen and bar displays now show accurate elapsed time for orders AND only display new items when checks reappear after being marked as served
  • Files modified: main/business/check.hh, main/business/check.cc

    • Calls System::ClearSystem(all) to remove all archived data, current data, and stock data
  • Safety: Requires 10 intentional taps before activation, prevents accidental data loss
  • Zone Type: ZONE_CLEAR_SYSTEM (ID: 107)
  • Usage: Available in zone editor dropdown as "Clear System" - place on Developer Settings or admin pages
  • Files modified: zone/button_zone.hh, zone/button_zone.cc, zone/pos_zone.hh, zone/pos_zone.cc, main/ui/labels.cc

Fixed

• Fixed DPI for Consistent Font Rendering Across All Displays (2025-12-XX)

  • Issue: With scalable fonts (Xft), each display device required different DPI settings, causing inconsistent font sizes across different displays
  • Solution: Implemented fixed DPI (96) for all font loading operations
    • All font specifications now automatically include :dpi=96 parameter
    • Ensures fonts render at the same size regardless of display DPI

  • Impact: Eliminates CMake deprecation warnings during build configuration
  • Files modified: CMakeLists.txt, cmake/gen_compiler_tag.cmake

• Self Order Drawer Access Issue (2025-11-20)

  • Issue: "No Drawer is Available for Payment" error inappropriately appeared in Self Order mode during payment settlement
  • Root Cause: Customer user (ID 999) on Self Order terminals did not have guaranteed drawer access, causing payment processing to fail even when payment was supposedly "immediate"
  • Fix: Modified FindDrawer() method to ensure Customer user on Self Order terminals always gets their own dedicated drawer using server bank logic, bypassing normal drawer mode restrictions
  • Impact: Self Order terminals can now properly process payments without drawer availability errors, maintaining the "immediate payment" functionality
  • Files modified: main/hardware/terminal.cc

• Credit Card Fee Tax Calculation (2025-11-17)

  • Issue: Credit card fees (both dollar and percentage amounts) were not being included in tax calculations
  • Root Cause: Credit card fees were added to the transaction balance but not included in the taxable revenue bases used for tax calculations
  • Fix:
    • Credit card fees are now collected and added to taxable revenue after orders are processed
    • Percentage-based fees are recalculated after raw_sales is known to ensure accurate amounts
    • Fees are distributed proportionally across all tax revenue bases (food, alcohol, room, merchandise) to ensure they're included in all applicable tax calculations
    • Fees are added after the takeout check to prevent them from being zeroed out when takeout food isn't taxed
    • Food tax is recalculated after fees are added to include tax on the fees
  • Impact: Credit card fees are now properly taxed according to the applicable tax rates (food tax, alcohol tax, GST, PST, HST, QST, room tax, merchandise tax, VAT)
  • Files modified: main/business/check.cc

• Critical Bug Fixes - Memory Leaks and Security Issues (2025-11-13)

  • Issues: Multiple critical bugs causing file descriptor leaks, memory leaks, and buffer overflow vulnerabilities

       • Fixed socket leak in ListAddresses() - socket properly closed before function return
    2. Memory Leaks:
       • Fixed JobInfo allocation failure handling in 3 locations (NewSelfOrder, QuickMode, Terminal setup)
       • Added proper cleanup: delete Employee object if JobInfo allocation fails
       • Prevents memory leak when allocation fails during Customer user creation
    3. Buffer Overflow Vulnerabilities:
       • Replaced unsafe strcpy() with strncpy() with proper null termination in OpenTerminalSocket()
       • Replaced all sprintf() calls with snprintf() with buffer size checks (4 locations)
       • Eliminates potential buffer overflow attack vectors
    4. Code Quality Improvements:
       • Extracted duplicated Customer Employee creation logic into centralized helper function GetOrCreateCustomerUser()

• Medium Priority Bug Fixes - Memory Safety Improvements (2025-11-13)

  • Issues: Potential infinite loop in order deletion and unclear ownership semantics in Copy methods
  • Fixes:
    1. Order Deletion Safety (zone/order_zone.cc):
       • Added safety counter (max 1000 modifiers) to prevent infinite loops if list corruption occurs
       • Added corruption detection to verify Remove() properly unlinked items
       • Added error logging to help debug any list corruption issues
       • Protects against crashes from use-after-free or double-free scenarios
    2. Smart Pointer Copy Methods:
       • Added SubCheck::CopyUnique() returning std::unique_ptr<SubCheck> for safe memory management
       • Complements existing Order::CopyUnique() for consistent modern C++ patterns
       • Eliminates ambiguity about ownership of copied objects
       • Prevents memory leaks when callers forget to delete copied objects
  • Impact:
    • Prevents potential infinite loops and crashes from list corruption
    • Improves code safety with clear ownership semantics
    • Modernizes codebase with C++11/14/17 best practices
  • Files modified: zone/order_zone.cc, main/business/check.hh, main/business/check.cc

• Double Modifier Decimal Multiplier (2025-11-11)

  • Issue: Developer settings rejected fractional double multipliers, causing charges to ignore decimal values when combining multiply and add/subtract adjustments
  • Fix: double_mult now stores a floating-point multiplier with proper rounding, allowing values like 1.5 or 0.75 to work alongside double_add
    • Updated Settings serialization to version 104 with backward compatibility for legacy integer values
    • Adjusted SalesItem::Price() to compute the final price using floating-point math with cent rounding
    • Developer settings UI accepts and displays decimal multipliers without truncation
  • Impact: Fractional double pricing now calculates correctly for decimal multipliers and additive/subtractive adjustments
  • Files modified: main/business/sales.cc, main/data/settings.{hh,cc}, zone/settings_zone.cc, docs/changelog.md

• Tax Calculation Including Modifiers (2025-11-05)

  • Issue: Tax calculation was inconsistent between main checkout system and per-order display
  • Root Cause: Order::CalculateTax() used cost (excluding modifiers) while main system used total_cost (including modifiers)
  • Fix: Updated Order::CalculateTax() to use total_cost instead of cost for consistent tax calculation
    • Changed taxable amount calculation on line 5855 of main/business/check.cc
    • Tax now properly includes modifier costs across all calculation methods
  • Impact: Tax is now consistently calculated on order total including modifiers throughout the system
  • Files modified: main/business/check.cc

• Image Selection "None" Not Persisting (2025-11-05)

  • Issue: Setting an image to "None" in button properties would not save - previous image would reappear after save
  • Root Cause: Auto-restoration logic in order_zone.cc was restoring images from item data whenever zone's ImagePath was empty
  • Fix: Changed image sync logic to be one-way (zone → item) instead of bi-directional
    • Removed auto-restore from item to zone (lines 1555-1558)
    • Added explicit clearing of item's image when zone is set to "None"
    • Zone's image selection (including "None") now properly persists
  • Impact: Users can now set images to "None" and the selection properly saves and persists
  • Files modified: zone/order_zone.cc

• Self-Order Check Accumulation (2025-11-04)

  • Issue: Multiple open checks were being created when customers made orders or left without placing orders on self-order terminals
  • Root Cause: QuickMode() was creating a new check every time without cleaning up previous empty checks for the Customer user
  • Fix: Added cleanup logic to destroy any existing empty checks for Customer user before creating a new one
    • Checks for empty checks owned by Customer user (ID 999) before creating new check
    • Only destroys checks with serial_number > 0 to avoid issues with newly created checks
    • Prevents accumulation of abandoned checks when customers browse menu without ordering
  • Impact: Self-order terminals now maintain only one check per customer session instead of accumulating multiple open checks
  • Files modified: main/hardware/terminal.cc

• 🖼️ Global Button Image Toggle (2025-11-08)

  • Settings Switch: Added "Show Button Images" toggle to Settings switches so users can enable/disable images globally
    • New switch constant SWITCH_BUTTON_IMAGES toggles the global default
    • Updated SwitchZone to render and handle the new toggle
  • Terminal Sync: Terminals now adopt the global default on setting changes while still allowing per-terminal overrides via the existing toggleimages signal
    • Terminals mark active pages dirty so UI refreshes immediately after toggles
  • Persistence: Stored global preference in settings data (show_button_images_default) with SETTINGS_VERSION bumped to 103
    • Load/Save logic reads and writes the persisted flag
  • Files modified: main/data/settings.{hh,cc}, zone/settings_zone.cc, main/ui/labels.cc, main/hardware/terminal.cc

• 🚀 Edit Mode Drag Performance (2025-11-08)

  • Deferred Rendering: Suspending full page redraws while dragging zones now relies on a lightweight overlay preview for immediate feedback
  • Preview Overlay: The editor draws a dynamic drag rectangle so button moves stay responsive even while the cursor is in motion, even for multi-zone selections
  • Minimal Repaint Path: Continuous drag updates now mutate an off-screen region accumulator instead of forcing zone re-rendering and pixmap uploads each mouse move
  • Final Commit: Zone positions only redraw once at drop time, keeping X11 smooth and eliminating freeze-like behavior when moving image-heavy buttons
  • Shadow Awareness: Drag preview and final redraw take zone shadows into account so what you see during the move precisely matches the drop result
  • Files modified: main/hardware/terminal.{hh,cc}, zone/zone.{hh,cc}

• 📋 Dialog Menu Multi-Column Layout for Long Lists (2025-11-04)

  • Multi-Column Display: Button properties dialogs with more than 8 options now automatically display in multiple columns instead of going off-screen
    • Modified DialogMenu::Init() in term/term_dialog.cc to detect long option lists
    • When > 8 items are present, menu uses XmPACK_COLUMN with automatic column calculation (8 rows per column)
    • Each additional 8 items creates a new column, keeping menus fully visible on screen
    • Applies to all dropdown fields in button/zone properties dialogs (type, behavior, colors, fonts, etc.)
  • Files modified: term/term_dialog.cc
  • Result: Long dropdown menus in properties dialogs now stay on screen with multi-column layout instead of requiring scrolling off-screen

• 🖼️ Image Button Transparency and Text Overlay Support (2025-11-04)

  • PNG Transparency: Fixed PNG transparency to properly use alpha channel masking instead of filling transparent pixels with gray
    • Added mask pixmap support to Xpm class for proper transparency rendering
    • Updated LoadPNGFile() to create 1-bit mask pixmap for alpha channel
    • Modified Layer::DrawPixmap() to use XSetClipMask for proper transparency compositing
    • Transparent backgrounds now show the button texture underneath
  • Text Overlay on Image Buttons: Button text and prices now display with configurable positioning
    • Added button_text_position setting: 0=over image (default), 1=above image, 2=below image
    • Setting accessible in General Settings page under "Button Text Position" dropdown
    • Text is drawn with proper contrast and shadows for readability on images
    • Text automatically splits button into 70/30 ratio when positioned above/below
  • Image Display Mode Toggle: Added per-terminal control for showing/hiding button images
    • Added show_button_images flag to Terminal class for per-terminal image display control
    • Added toggleimages signal command for runtime toggling (affects only the terminal issuing command)
    • Create a message button with signal "toggleimages" to toggle between modes
    • Each terminal can independently show images or text-only mode without affecting other terminals
  • Settings Version: Incremented to version 102 for new display settings (deprecated show_button_images moved to per-terminal flag)
  • Files modified: term/term_view.{hh,cc}, term/layer.cc, zone/button_zone.cc, main/hardware/terminal.{hh,cc}, main/data/settings.{hh,cc}
  • Result: PNG images with transparency display correctly, text is readable on all image buttons with configurable position, and users can toggle image display mode

• 🖼️ Image Button Rendering Refresh (2025-11-02)

  • Button zones now paint selected images behind the frame using the interior content area.
  • Image filenames persist via updated PosZone serialization (ZONE_VERSION 29) so saves and copies keep selections.
  • Copying any button-like zone (Message, Conditional, Image button, etc.) retains its associated image.
  • Files touched: zone/button_zone.{hh,cc}, zone/pos_zone.{hh,cc}.
  • Result: Selecting a PNG/JPG/GIF in Button Properties immediately shows on-screen and survives page reloads.

• System Page Validation Function: Added ZoneDB::ValidateSystemPages() to detect data integrity issues

  • Purpose: Checks for System Pages (PAGE_SYSTEM = 0) with invalid parent_id values (> 0)
  • Detection: Identifies corrupted data files where System Pages incorrectly have parent relationships
  • Reporting: Logs detailed error messages and returns count of invalid pages found
  • Usage: Can be called during startup or maintenance to verify data integrity

• Self-Order Terminal Navigation and System Operations: Comprehensive fixes for Customer user navigation, check management, and system operations

  • Issue 1 - Regular Employee Navigation: Regular employees were being sent to page -2 (self-order page) when clicking "Restart" button or using "Return To The Starting Page" jump option
    • Root Cause: Navigation functions were using page_variant setting without checking user type
    • Fix:
      • Added GetDefaultLoginPage() helper function that checks if user is "Customer" - only Customer user goes to page -2, all others go to page -1
      • Updated CancelOrders() to use GetDefaultLoginPage() instead of hardcoded page -2
      • Updated HomePage() to skip page_variant logic for regular employees on FASTFOOD/NORMAL terminals
      • Updated LogoutUser() to call GetDefaultLoginPage() before clearing user context
  • Issue 2 - Customer Navigation to Tables: Customer user was incorrectly navigated to table pages when clicking interactable buttons
    • Root Cause: HomePage() was falling back to FirstTablePage() when page -2 wasn't found
    • Fix: Added early return in HomePage() to always send Customer user directly to page -2
  • Issue 3 - Unclosed Checks: Checks remained open when Customer canceled or left without completing order
    • Root Cause: CancelOrders() and StoreCheck() were keeping checks for SELFORDER terminals
    • Fix:
      • Updated CancelOrders() to destroy checks for Customer user when canceling
      • Updated StoreCheck() to destroy empty checks for Customer user
      • Regular employees' checks are still preserved
  • Issue 4 - Blocked System Operations: Customer being always logged in prevented shutdown/restart/end-of-day operations
    • Root Cause: TermsInUse() and OtherTermsInUse() counted Customer user, preventing operations when count > 0
    • Fix:
      • Updated TermsInUse() to exclude Customer user from count
      • Updated OtherTermsInUse() to exclude Customer user from count
      • Customer user no longer blocks shutdown, restart, end-of-day, or credit card settlement operations
  • Impact:
    • Regular employees correctly return to page -1 (login page)
    • Customer user stays on page -2 (self-order page) and never navigates to table pages
    • Incomplete orders are automatically cleaned up when Customer cancels or leaves
    • System operations (shutdown/restart/end-of-day/CC settlement) work correctly even with Customer logged in

Fixed

• Hardware Settings Duplication Bug: Fixed critical issue where printer and display settings were being duplicated in Hardware configuration

  • Root Cause: Hardware zone was automatically clearing printer_host when it matched display_host, creating a circular dependency
  • Problematic Logic: StringCompare(ti->display_host.Value(), ti->printer_host.Value()) == 0 would clear printer_host
  • Fallback Conflict: Settings fallback logic would then set printer_host back to display_host, creating duplication

• Version Number and Date Update: Updated version number to reflect current year and fixed version date display in Page 1 lower left corner
  • Version Number: Updated from "21.05.1" to "25.01.1" to reflect current year 2025
  • Version Date: Fixed version date display to show current build date (2025-09-18) instead of cached 2021 date
  • Root Cause: Version timestamp was correctly generated but cached version_generated.hh file contained old date
  • Solution: Updated version.cmake with new major/minor version numbers and regenerated version files with make clean and make
  • Result: Version display now correctly shows "POS 25.01.1-74 2025-09-18" with current year and build date
• SelfOrder Mode Differentiation: Added support for SelfDineIn and SelfTakeOut check types in SelfOrder mode
  • New Check Types: Added CHECK_SELFDINEIN (11) and CHECK_SELFTAKEOUT (12) to distinguish between dine-in and take-out orders
  • Enhanced Methods: Added IsSelfDineIn() and IsSelfTakeOut() methods to Check class for proper type identification
  • Updated Logic: Modified IsSelfOrder(), IsTakeOut(), and IsForHere() methods to include new SelfOrder variants
  • Terminal Support: Updated QuickMode() method to handle new SelfOrder check types with proper validation
  • Files Modified: main/check.hh, main/check.cc, main/terminal.cc
• SelfOrder Drawer Access Issue: Fixed "No Drawer Available" message when drawer is configured for SelfOrder terminals
  • Root Cause: Customer user (ID 999) created for SelfOrder terminals lacked SECURITY_SETTLE permission needed for drawer access
  • Solution: Updated Customer user setup to include SECURITY_SETTLE permission in addition to existing SECURITY_TABLES and SECURITY_ORDER
  • Implementation: Modified all three Customer user creation locations in main/terminal.cc to grant proper permissions
  • Result: SelfOrder terminals can now properly access drawers for payment processing without errors
• Check Type Constants Backward Compatibility: Fixed data corruption issue caused by renumbering existing check type constants
  • Problem: Renumbering CHECK_DINEIN, CHECK_TOGO, and CHECK_CALLIN from values 11-13 to 13-15 broke backward compatibility
  • Impact: Saved checks with old type values (11 for CHECK_DINEIN) were misinterpreted as new types like CHECK_SELFDINEIN, causing incorrect behavior and data corruption
  • Solution: Restored original values for existing constants and reassigned new values to CHECK_SELFDINEIN and CHECK_SELFTAKEOUT
  • New Values: CHECK_DINEIN=11, CHECK_TOGO=12, CHECK_CALLIN=13, CHECK_SELFDINEIN=14, CHECK_SELFTAKEOUT=15
  • Result: Existing saved checks with old type values now work correctly without data corruption
• IsToGo() Method Consistency: Fixed inconsistency in IsToGo() method to include CHECK_SELFTAKEOUT
  • Problem: IsToGo() method didn't account for CHECK_SELFTAKEOUT, creating inconsistency with other related methods
  • Impact: Self-service takeout orders (CHECK_SELFTAKEOUT) were not properly identified as "to go" orders
  • Solution: Updated IsToGo() method to include CHECK_SELFTAKEOUT check type
  • Consistency: Now matches pattern used in IsTakeOut() and IsForHere() methods which include their corresponding self-service types
  • Result: Self-service takeout orders are now correctly identified as "to go" orders
• Allow settlement after reset for users with Settle permission
  • Removed terminal-type restriction in Terminal::CanSettleCheck() that blocked settling on ORDER_ONLY terminals after reset
  • Settlement still requires a valid drawer and respects ownership/supervisor checks
• fix configure step by searching for PkgConfig before using pkg_check_module #128
• update embedded catch.hpp to v2.13.10 to fix compilation on Ubuntu 20.04 and newer #131
• Fixed: Changing font now updates all UI elements, including toolbar and dialog buttons, not just some zones
• Fixed: UI no longer breaks or crashes when switching to scalable fonts; only compatible fonts are shown
• Fixed: Font size and weight selection no longer causes crashes or mismatches
• Fixed: Catch2 v3 migration completed successfully with all tests passing
• Fixed: "Receipts Balance & Cash Deposit" report no longer causes infinite loading cursor on clean installations
  • Added early exit in BalanceReportWorkFn when no checks exist to process
  • Prevents work function from being rescheduled indefinitely when database is empty
  • Report now completes immediately and shows appropriate empty state
• Fixed: "Refresh ViewTouch" Hanging Issue
  • Root Cause: Segmentation fault in XtRemoveInput() during X11 resource cleanup
  • Problem: ViewTouch would hang on "Shutting Down" when trying to remove X11 input handlers with invalid context
  • Solution: Added proper validation and error handling for all XtRemoveInput() calls
    • Added App != NULL check in RemoveInputFn() before calling XtRemoveInput()
    • Wrapped XtRemoveInput() calls in try-catch blocks in term_view.cc
    • Added error logging for invalid Xt context scenarios
    • Ensured input IDs are properly reset to 0 after removal
  • Files Modified:
    • main/manager.cc - Enhanced RemoveInputFn() with context validation
    • term/term_view.cc - Added exception handling in SocketInputCB(), StopTouches(), and cleanup functions
  • Result: "Refresh ViewTouch" button now works correctly without hanging
  • Impact: System restart (sudo shutdown -r now) also works properly from within ViewTouch
  • Testing: Verified restart functionality with signal testing - old process terminates cleanly, new process starts successfully
