- New 'Deploy from GitHub' button downloads latest code directly
- No git configuration required - more reliable for git-unfriendly servers
- Automatically syncs changed files (skips .git, vendor, writable)
- Both methods available: git pull (if configured) or direct GitHub download
- Each has a clear confirmation dialog explaining the method
- Handles temporary extraction and cleanup automatically
This solves HMS deployment when git is not accessible to PHP process
Enhanced error reporting:
- Show detailed diagnostic information: git version, user config, email, remote, branch
- Check .git directory and config file existence
- Detect if repository has uncommitted changes
- Error categorization: PERMISSION, CONFIG, REPO, NETWORK, SSL, GIT errors
- Actionable error messages with command suggestions
- Report raw error output to log file for debugging
Added setup_git_config.sh script:
- Automated configuration for www-data user
- Creates .ssh directory with proper permissions
- Sets git user.name and user.email globally
- Disables SSL verification (for HTTPS repos)
- Configures git to use HTTPS remote URL
- Fixes directory ownership and permissions
- Tests git status to verify configuration
Usage on live server:
sudo bash setup_git_config.sh
This script handles the common git configuration issues
that prevent 'Update HMS' button from working.
- Added findGitCommand() method to check for git in common locations:
* /usr/bin/git (standard Linux)
* /bin/git (alternative location)
* /usr/local/bin/git (compiled from source)
* Falls back to 'which git' and 'command -v git'
- Uses absolute git path in all shell commands
- Fixes 'Git command not found' error on systems where git is not in PATH
- No dependencies added, uses PHP file_exists() + is_executable() checks
Pre-checks before git pull:
- Verify .git directory exists
- Check if git command is available
- Run git status to detect permission/connectivity issues
Better error messages for common failures:
- Permission denied → 'Git directory may not be writable'
- Authentication failed → 'SSH keys may not be configured for www-data'
- Connection refused → 'GitHub server unreachable'
- fatal errors → Parse and return specific error details
Returns actual error message instead of generic 'Check logs for details'
- Method 1: ping to Google DNS (8.8.8.8)
- Method 2: DNS resolution via nslookup
- Method 3: DNS query using dig
- Method 4: curl HTTP HEAD to google.com
- Method 5: wget --spider
- Method 6: fsockopen to Google DNS (8.8.8.8:53)
- Method 7: curl to Cloudflare DNS (1.1.1.1)
- Method 8: PHP gethostbyname() for DNS resolution
Tries multiple DNS providers (Google, Cloudflare, Quad9)
Falls back to 'Offline' only if all methods fail
Handles firewalls, ICMP blocks, and missing commands
- Method 1: \['SERVER_ADDR'] from Apache/Nginx (most reliable)
- Method 2: /sbin/ip (absolute path, works if ip not in PATH)
- Method 3: Parse /proc/net/route for default gateway interface + IP
- Method 4: hostname -I (space-separated IPs)
- Method 5: ifconfig (fallback for older systems)
- Method 6: Socket connection to 8.8.8.8 (pure PHP, no shell commands)
Each method validates IP and skips loopback (127.x, ::1, ::ffff:127.x)
Fixes 'Unavailable' when shell commands fail or aren't available
- Changed primary method to: ip -4 addr show scope global (gets public/private IPs only)
- Added isLoopbackIp() helper to filter out loopback addresses (127.* and ::1)
- Fallback: hostname -I with loopback filtering
- Last resort: gethostbyname() with loopback check
- On remote server with eth0: 159.89.175.190, will now show public IP instead of 127.0.0.1
Three-level fallback chain:
1. gethostbyname(gethostname()) - PHP built-in, works on Linux and Windows
2. ip -4 addr show scope global | grep inet - Linux shell fallback
3. hostname -I - Linux shell secondary fallback
All results validated with FILTER_VALIDATE_IP before display.
Update improvements:
- Renamed button from "Update System" to "Update HMS"
- Changed update to run only 'git pull' (removed database migrations)
- Added 60-second timeout to prevent system hangup
- Better error messages for timeouts and failures
- Logs update status (running/success/failed/timeout) to history
- Confirmation dialog now says "Pull latest HMS code from repository?"
This ensures quick updates without long-running migrations that could hang
the admin interface. Database migrations can be run separately as needed.
Resource Usage improvements:
- Added visual progress bars for CPU, RAM, and Disk usage
- Progress bars use Bootstrap styling (success/info/warning colors)
- Display percentage and detailed metrics (e.g., RAM 4 / 128 MB (3%))
- Bars animate smoothly with CSS transitions
CPU detection enhancements:
- Added fallback to /proc/stat parsing when shell commands unavailable
- Added fallback to PHP getrusage() for CPU time estimation
- CPU now displays even when shell_exec is disabled
- Graceful fallback chain ensures data is always available
Progress bar styling:
- Success (green) for CPU
- Info (blue) for RAM
- Warning (orange/yellow) for Disk
- All bars styled with height, rounded corners, and smooth transitions
When shell_exec() is disabled on the server (common in production), the system
operations panel now gracefully falls back to PHP built-in functions:
- gethostname() for hostname instead of shell 'hostname' command
- php_uname() for OS info instead of shell 'uname -a' command
- /proc/uptime parsing or unavailable status for uptime
- disk_free_space() and disk_total_space() for disk usage
- memory_get_usage() and PHP memory limit for memory usage
- Improved parsePhpMemoryLimit() to handle memory limit parsing
This ensures the admin panel shows meaningful information even in restricted
production environments where shell_exec is disabled for security reasons.
- Added System Operations link to Admin dashboard (app/Views/Setting/Admin/index.php)
- Uses load_form_div to load the system operations page inline
- Added SystemOperations library for server status collection and actions
- Tile uses server icon (bi-server) and appears in the admin panel grid
- Link: javascript:load_form_div(base_url('setting/admin/system-ops'), 'maindiv', 'System Operations')
