Real-time Updates: Live progress tracking and log streaming during generation

Smooth Progress Bar Fix

[COMPLETE] 2025-01-21: SMOOTH PROGRESS BAR 40% TO 100%

Full Range Progress: Progress bar smoothly moves from 40% to 100% during compilation
No Stuck Progress: Fixed issue where progress was stuck at 40%
Gradual Movement: Progress increases steadily over the estimated compilation time
File Size Based: 10MB L5X = 15 minutes, scales proportionally
Default Fallback: Uses 15-minute default if L5X file size can't be determined
No Jumps: Progress moves smoothly without any sudden jumps
Completion at 100%: Progress reaches 100% when compilation finishes

Progress Jump Fix

[COMPLETE] 2025-01-21: FIXED PREMATURE PROGRESS JUMPS

Removed Generic Matchers: Removed "SUCCESS" and "COMPLETED" from progress map to prevent false matches
Specific Phase Matching: Now only updates progress on specific phase completion messages
Compilation Lock: Once compilation starts, progress updates from log messages are blocked
Controlled Flow: Progress follows this pattern:
- 0-38%: Quick progress through initial phases
- 38%: L5X file created, size detected
- 40-90%: Gradual progress during compilation based on file size
- 90-92%: Compilation completed
- 92-98%: "WORKFLOW COMPLETED SUCCESSFULLY" message
- 100%: Job complete
Thread Synchronization: Waits for compilation thread to finish before final progress updates
No False Triggers: Generic [SUCCESS] messages in logs no longer cause progress jumps

Duration Timer Fix

[COMPLETE] 2025-01-21: FIXED DURATION TIMER STUCK AT 0s

Root Cause: Duration timer was trying to parse localized date string instead of raw timestamp
Solution 1: Store raw start time in data-start-time attribute for reliable parsing
Solution 2: Simplified timer logic to always use data attribute instead of checking status text
Solution 3: Timer now properly stops when job completes or fails
Result: Duration counter starts from 0s and updates every second while job is running

Simplified Duration Counter

[COMPLETE] 2025-01-22: REPLACED DURATION LOGIC WITH SIMPLE COUNTER

Removed Complexity: Stripped out all new Date() and toLocaleString() parsing from the timer.
Simple Increment: The timer is now a basic setInterval function that increments a counter by one every second.
Clean Display: The duration shows a simple integer followed by "s" (e.g., "1s", "2s", "3s"...).
Correct Start/Stop: The updateStatus function now correctly starts the timer only when job.status is "running" and stops it on "completed" or "failed", without any conflicting logic.
No Race Conditions: Removed the redundant timer start on page load, preventing the timer from starting prematurely.
Result: The duration counter is now extremely simple, robust, and does exactly what was requested: starts at 0s and ticks up every second.

Compilation Progress Start Fix

[COMPLETE] 2025-01-21: FIXED DELAYED COMPILATION PROGRESS

Immediate Detection: Progress bar now starts moving as soon as "PHASE 4" begins
Active File Search: If L5X file wasn't found earlier, actively searches when Phase 4 starts
Default Fallback: If L5X file can't be found, uses default 15-minute estimate
No More Delays: Progress starts immediately at 40% when compilation begins
Better Detection: Triggers on "PHASE 4", "compilation", or "starting conversion" messages

Log Capture Fix

[COMPLETE] 2025-01-21: FIXED MISSING LOGS AFTER PHASE 1

Line Buffering: Added bufsize=1 to subprocess for real-time line-by-line output
Force Flush: Added sys.stdout.flush() after each log entry
Unbuffered Output: Configured Python output to be unbuffered in streamlined_generation.py
Timeout Protection: Added 30-minute timeout to prevent hanging processes
Better Error Handling: Process timeouts now properly report errors

Fast Compilation Detection

[COMPLETE] 2025-01-21: SMOOTH PROGRESS BAR ALWAYS

No Progress Jumps: Progress bar always moves smoothly, even if compilation completes early
Gradual Movement: Progress continues gradually from 40% to 90% based on estimated time
Completion Handling: When compilation finishes early, progress continues smoothly to 90%
No Interruptions: Progress thread runs for full estimated duration regardless of actual completion
Maximum 5% Steps: Even after compilation, progress updates are limited to 5% increments
User Experience: Consistent, predictable progress bar movement without sudden jumps

Progress to 100% Fix

[COMPLETE] 2025-01-21: PROGRESS REACHES 100% ON COMPLETION

Completion Detection: When "WORKFLOW COMPLETED SUCCESSFULLY" is seen, compilation_in_progress is set to false
Final Update: Job completion always sets progress to 100%
Log Confirmation: Added "Job completed - progress set to 100%" log message
Smooth Transition: Progress goes 98% → 100% when job completes
No Blocking: 98% progress doesn't block the final 100% update

Fast Compilation Progress Jump

[COMPLETE] 2025-01-22: JUMP TO 100% ON FAST COMPILATION

Completion Detection: When "Conversion completed successfully" is logged, it signals an early finish.
Stop Animation: A threading.Event is now used to immediately stop the smooth progress animation thread.
Jump to 100%: The progress_map is configured to set the progress directly to 100% upon seeing the completion message.
Cleaned Up Logic: Removed redundant checks and allowed the progress_map to handle the final state, resulting in a more robust implementation.
Result: If compilation finishes faster than the estimate, the progress bar will now instantly jump to 100%, providing immediate feedback.

Corrected Compilation Time Estimate

[COMPLETE] 2025-01-22: RECALIBRATED COMPILATION TIME ESTIMATE

User Feedback: The previous estimate of 11.3 minutes for a 7.55MB file was incorrect.
New Requirement: A 7.5MB file should estimate a 20-minute compilation time.
Recalculated Multiplier: The time-per-megabyte multiplier was adjusted from 90 to 160.
Updated Formula: The new formula is estimated_duration = l5x_file_size_mb * 160.
Result: The time estimate is now accurate based on the new requirement, ensuring the progress bar animation is correctly paced.

MCM01 Zone Configuration

[COMPLETE] 2025-01-22: ADDED MCM01 ZONE CONFIGURATION

Refactored zones_config.py: Restructured the file to hold a dictionary of zone configurations (ZONES_CONFIGS), keyed by project type (MCM01, MCM04).
Added MCM01 Zones: Included the new zone data for MCM01 as provided.
Updated streamlined_generation.py: Modified the script to dynamically select the correct zone configuration from ZONES_CONFIGS based on the --project-name argument.
Default Fallback: Set MCM04 as the default configuration to ensure backward compatibility.
Result: The application can now generate projects for both MCM01 and MCM04 with their respective zone control logic.

Unicode Hotfix for IO Tree Generator

[COMPLETE] 2025-01-22: FIXED UNICODEENCODEERROR IN IO TREE GENERATOR

Root Cause: The print(result.stdout) call in run_io_tree_generator was failing on Windows when the output contained characters not supported by the default charmap codec.
Solution: Wrapped the print statement in a try...except UnicodeEncodeError block.
Fallback: If a UnicodeEncodeError is caught, the output is encoded to ASCII, ignoring any problematic characters, ensuring the program can continue without crashing.
Result: The generation process is now more robust and will not fail due to console display limitations on Windows.

Ubuntu 24.04 Python Compatibility Fix

[RESOLVED] 2025-01-22: PYTHON VERSION COMPATIBILITY ISSUE

Issue: Ubuntu 24.04 (Noble) uses Python 3.12 by default, not Python 3.11
Symptoms: E: Unable to locate package python3.11 during apt installation
Root Cause: Original setup script hardcoded Python 3.11 requirements
Solution: Updated dev_setup_linux.sh to use system Python 3 version automatically
Quick Fix: Created fix_python_setup.sh for immediate resolution
Result: Full compatibility with Ubuntu 24.04 LTS default Python installation

WSL EnsurepIp Error Fix

[RESOLVED] 2025-01-22: VIRTUAL ENVIRONMENT CREATION FAILURE

Issue: Command '[...python3', '-m', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1
Symptoms: Virtual environment creation fails during pip installation phase
Root Cause: WSL Ubuntu environments often have broken ensurepip functionality
Solution: Created wsl_ensurepip_fix.sh with manual pip installation and virtualenv usage
Technical Fix:
- Downloads get-pip.py to install pip manually (bypasses ensurepip)
- Uses virtualenv instead of venv for better WSL compatibility
- Adds proper PATH handling for user-installed packages
Result: Robust virtual environment creation that works reliably in WSL

Plan

Objective

Refactor the Routines Generator so that the current limited generation workflow becomes the primary implementation. All existing full-feature generators will be preserved in a new legacy/ folder for future rebuilds.

High-Level Steps

Inventory & Analysis
- Map all generator classes, CLI entry points, and routine modules currently in use.
- Identify dependencies unique to the limited workflow vs. full workflow (e.g., LimitedDataLoader, limited routines, safety-only writers).
Repository Restructure
- Create Routines Generator/src/legacy/ and move the following into it: • generators/main_program.py • generators/safety_program.py • All routine modules not required by the limited workflow (device control, monitoring, process control, etc.).
- Retain limited equivalents (LimitedMainProgramGenerator, LimitedSafetyProgramGenerator, essential safety routines) in their current paths.
Promote Limited Generators
- Rename limited generator classes & files for clarity: • limited_main_program.py → main_program.py • limited_safety_program.py → safety_program.py
- Update internal class names accordingly and fix imports across the codebase.
CLI & Script Updates
- Modify src/cli.py so default commands (generate main, generate safety, generate all) call the new primary (formerly limited) generators.
- Add a --legacy flag or dedicated sub-command to access archived generators.
Tests & Regression Harness
- Update pytest suites to point at the new default generators.
- Mark legacy tests with @pytest.mark.legacy and skip by default.
Continuous Integration Adjustments
- Ensure CI workflow only builds and tests the new main path unless LEGACY_TESTS flag is set.
Documentation & Migration Guide
- Update README and any developer docs to describe the new default workflow.
- Provide instructions for using legacy generators when needed.
Code Cleanup & Dead-Code Removal
- After restructuring, run static analysis (flake8/pylint) to remove unused imports and dead code.
End-to-End Validation
- Execute full generation pipeline (limited-now-main) against sample project.
- Compare output L5X and CSV files to current limited outputs to ensure parity.

Deliverables

Updated project structure with legacy/ folder.
Refactored generator files with updated import paths.
Updated CLI with new default behaviors.
Passing regression test suite focused on the new main workflow.
Documentation reflecting the refactor.

Log

[COMPLETE] Repository Restructure: Moved all full-feature routine modules into src/legacy/routines/ while leaving safety-critical ones in current location.
[COMPLETE] Legacy Package: Created proper src/legacy/routines/ package with __init__.py and all routine functions exported.
[COMPLETE] Back-compatibility Shim: Added dynamic import fallback in src/routines/__init__.py that tries local imports first, then falls back to legacy.routines.*.
[COMPLETE] Generator Aliasing: Updated src/generators/__init__.py to alias limited generators as primary exports (MainProgramGenerator = LimitedMainProgramGenerator).
[COMPLETE] CLI Updates: Enhanced CLI & scripts with --legacy flag to access full-feature generators when needed.
[COMPLETE] Import Path Fixes: Fixed relative imports in safety routine modules (from ..utils.common instead of from utils.common).
[COMPLETE] Comprehensive Fallbacks: Added all 17+ legacy routine functions to the import fallback system.
[COMPLETE] Validation: Confirmed generators import successfully without errors.

Final Structure

Primary Path: MainProgramGenerator → LimitedMainProgramGenerator (safety-only routines)
Legacy Path: FullMainProgramGenerator or --legacy flag → original full-feature generator
Routine Location: Safety routines in src/routines/, all others in src/legacy/routines/
Import Compatibility: Both from routines.dpm import create_dpm_routine and from legacy.routines.dpm import create_dpm_routine work
