From e07eef7581be781710ad17e703fd4810462350a9 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 16 Nov 2025 02:40:49 +0000 Subject: [PATCH 01/19] fix: Comprehensive launcher fixes for venv handling and dependency checking MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit applies critical fixes to the launcher to properly handle virtual environments and dependency checking on Ubuntu 24.04 systems. **Issues Fixed:** 1. **Fix Application Order** - Fixes were applied in the wrong order, causing venv creation to fail before python3-venv was installed - Now sorts fixes by priority: apt_install → ensurepip → create_venv → pip_install - Prevents broken venv creation 2. **Broken Venv Detection** - Existing venvs without pip weren't detected - Added detection for broken venvs (missing venv/bin/pip) - Automatically removes and recreates broken venvs - Validates pip exists after venv creation 3. **Wrong pip Used** - Package installation used system pip instead of venv pip - Modified pip_install to detect and use venv/bin/pip when available - Falls back to system pip if no venv exists 4. **Dependency Checks Failed** - After successful installation to venv, dependency checks still showed RED (errors) - Modified _check_packages() to use subprocess with venv/bin/python - Now correctly checks packages installed in venv - Falls back to __import__() for system environment 5. **Launch Commands Used Wrong Python** - Server/client launched with system Python, couldn't import venv packages - Updated launch_server() to use venv/bin/python when available - Updated launch_client() to use venv/bin/python when available - Both fall back to system Python if no venv **Result:** The launcher now correctly: - Installs system packages before creating venv - Creates functional venvs with pip - Installs dependencies to venv - Shows correct LED status (GREEN/YELLOW not RED) - Launches server/client with venv Python and dependencies --- lablink.py | 100 ++++++++++++++++++++++++++++++++++++++++++++++------- 1 file changed, 87 insertions(+), 13 deletions(-) diff --git a/lablink.py b/lablink.py index f1f1ac7..1339153 100755 --- a/lablink.py +++ b/lablink.py @@ -19,6 +19,7 @@ import subprocess import platform import json +import shutil from pathlib import Path from typing import List, Dict, Tuple, Optional from dataclasses import dataclass @@ -592,16 +593,37 @@ def _parse_requirements(self, req_file: Path) -> List[str]: return packages def _check_packages(self, packages: List[str]) -> Tuple[List[str], List[str]]: - """Check which packages are installed.""" + """Check which packages are installed. + + If a venv exists, checks packages in the venv. + Otherwise, checks packages in the current environment. + """ installed = [] missing = [] + # Determine which Python to use for checking + venv_python = Path("venv/bin/python") + use_venv = venv_python.exists() + for pkg in packages: - try: - __import__(pkg.replace('-', '_')) - installed.append(pkg) - except ImportError: - missing.append(pkg) + if use_venv: + # Check if package is installed in venv using subprocess + result = subprocess.run( + [str(venv_python), '-c', f'import {pkg.replace("-", "_")}'], + capture_output=True, + check=False + ) + if result.returncode == 0: + installed.append(pkg) + else: + missing.append(pkg) + else: + # Check if package is installed in current environment + try: + __import__(pkg.replace('-', '_')) + installed.append(pkg) + except ImportError: + missing.append(pkg) return installed, missing @@ -974,24 +996,68 @@ def apply_fixes(self, issues: List[CheckResult]): self.progress_bar.setVisible(True) self.progress_bar.setRange(0, len(issues)) - for i, issue in enumerate(issues): + # Sort fixes to ensure correct order of operations: + # 1. apt_install (system packages like python3-venv) + # 2. ensurepip (if needed) + # 3. create_venv (requires python3-venv to be installed) + # 4. pip_install (requires venv to exist) + def fix_priority(issue): + if issue.fix_command.startswith("apt_install:"): + return 0 + elif issue.fix_command == "ensurepip": + return 1 + elif issue.fix_command == "create_venv": + return 2 + elif issue.fix_command.startswith("pip_install:"): + return 3 + return 4 + + sorted_issues = sorted(issues, key=fix_priority) + + for i, issue in enumerate(sorted_issues): self.progress_label.setText(f"Fixing: {issue.name}") self.progress_bar.setValue(i) try: if issue.fix_command == "ensurepip": subprocess.check_call([sys.executable, '-m', 'ensurepip', '--upgrade']) + elif issue.fix_command == "create_venv": - subprocess.check_call([sys.executable, '-m', 'venv', 'venv']) + venv_path = Path("venv") + venv_pip = venv_path / "bin" / "pip" + + # If venv exists but pip doesn't, it's broken - delete it + if venv_path.exists() and not venv_pip.exists(): + self.progress_label.setText("Removing broken venv...") + shutil.rmtree(venv_path) + + # Create venv if it doesn't exist + if not venv_path.exists(): + subprocess.check_call([sys.executable, '-m', 'venv', 'venv']) + + # Verify pip was created + if not venv_pip.exists(): + raise Exception(f"venv created but {venv_pip} not found.

Set up logging with DEBUG level - Logs to both lablink_debug.log file and console - Format: timestamp - level - function:line - message - Log startup banner on launch 2. **System Check Logging** - check_all(): Logs "Starting comprehensive system check" - on_env_checked(): Logs completion with result count and details - update_led_status(): Logs LED updates with status and color 3. **Fix Application Logging** (apply_fixes method) - Logs all fixes to be applied - Logs environment status (externally managed, venv exists) - Logs each fix step with progress (1/5, 2/5, etc.) - Logs ensurepip execution - Logs venv creation/recreation with detailed steps - Logs pip package installation with pip path used - Logs apt package installation - Logs errors with full traceback - Logs completion and re-check trigger **Result:** Debug log file (lablink_debug.log) now captures: - All system checks and their results - LED status updates - Every fix attempted and its outcome - Errors with full stack traces - Environment and venv status throughout the process This makes it much easier to diagnose issues when the launcher encounters problems on different systems. --- lablink.py | 51 +++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) diff --git a/lablink.py b/lablink.py index 1339153..9d44845 100755 --- a/lablink.py +++ b/lablink.py @@ -20,11 +20,28 @@ import platform import json import shutil +import logging from pathlib import Path from typing import List, Dict, Tuple, Optional from dataclasses import dataclass from enum import Enum +# Configure logging +logging.basicConfig( + level=logging.DEBUG, + format='%(asctime)s -
