- Skip problematic global .gitconfig in /var/www
- Use local repository config (.git/config) instead
- Avoids permission issues with /var/www directory
- Public repos don't need global config
- Simpler 4-step process with better error handling
- Create .gitconfig as www-data user (not root)
- Ensures file has correct owner and permissions from creation
- Add fallback to use local repository git config if global fails
- Prevents 'could not lock config file' permission errors
This fixes the issue where www-data user cannot write to root-owned files
For public repos, only minimal git config needed:
- Fix corrupted .gitconfig file
- Set git user.name and user.email (required by git)
- Remove unnecessary SSL and SSH configuration
- Fix directory permissions for www-data user
- Test git status
Removed:
- SSH key setup (not needed for public repos)
- SSL verification config (not needed for public HTTPS)
- HTTPS remote URL configuration (already correct)
Updated from 8 steps to 5 simpler steps
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'
This file can be used to verify that the 'Update HMS' button successfully
pulls from GitHub on the live server. If this file appears in your remote
server directory after git pull, the update mechanism is working correctly.
- 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.
- Fixed split @media print blocks that caused all print rules to be orphaned
(gallery section had added its own block which broke the main rules)
- Consolidated into one clean @media print block with proper A4 settings
- Print improvements: cover fills page 1, intro on page 2, each section
starts on new page, screenshots print at fixed height, 3-col gallery grid
- Added "How to save as PDF" button with step-by-step modal overlay
- Steps guide: Destination → Save as PDF, A4 Portrait, Background graphics
- Both print bar buttons hidden in @media print
- @page: A4 portrait, 14mm/12mm/18mm margins, first page margin 0
- Added 9-card screenshot gallery section between intro and features
- Cards for: Dashboard, Patient Management, ABHA Creation, OPD Queue,
Bed Status Map, Charge Master/Insurance Rates, Stock Control Center,
Report Panel, Admin Panel
- Lightbox overlay for full-screen image viewing (keyboard Escape to close)
- Placeholder icons shown now; replace with real images by dropping PNGs
into public/assets/img/screenshots/ and updating src on each card
- Added gallery CSS with hover lift effect and lightbox styles
- Print-friendly: lightbox hidden in @media print
- Added "View HMS Features & Capabilities" link below the login card
- Copied HMS_FEATURES_PRESENTATION.html to public/ so it is accessible
via base_url without auth (same pattern as software-use-license.html)
- Link opens in a new tab
- HMS_FEATURES_PRESENTATION.html: full styled presentation with cover,
professional introduction, 11 feature sections, tech stack, compliance,
print/PDF button, and proper @media print A4 layout
- HMS_FEATURES_PRESENTATION.md: plain Markdown version of the same content
- system_ops.php: fix confirm dialog text for Update HMS button
- Added "Details" column to Update History table
- Shows info icon button when error details are available
- Clicking button opens a modal with full error message
- Details displayed in pre-formatted text for easy reading
- Helps diagnose why HMS updates failed or timed out
When an update fails, users can now click the info icon to see the exact
git error output, making troubleshooting much easier.
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')
- Added SystemOps controller with index and panel endpoints for dynamic content refresh
- Created system_ops_panel.php fragment for AJAX-based UI updates (no full page reload)
- Implemented 30-second auto-refresh using AJAX instead of location.reload()
- Fixed health badge contrast by adding explicit dark text color (#1f2937)
- Added jQuery availability checks to prevent script errors on page load
- Included server overview, resource usage, services, events, and update history
- Integrated delegated event handlers for action buttons (Update, Restart, Reboot, Shutdown)
- All buttons are protected with confirmation dialogs
- Layout maintains NiceAdmin card styling and responsive design
Routes added:
- GET /admin/system-ops/panel - returns panel fragment for refresh
- Diagnosis.php: resolve doctor mapping via ABDM Report Doctor Mapping,
compile pathology/diagnosis reports into separate Letter Head and
Plain Paper PDFs, add compiled-pdf-links endpoint
- Routes.php: add diagnosis/compiled-pdf-links route
- pathology_detail.php: render/persist dual compiled PDF buttons
- Setting/Template.php: per-modality Letter Head / Plain Paper template
mapping via hospital_setting keys
- Setting/Template/index.php: fix tile links using load_form (which only
replaces #main) instead of load_form_div, which broke every internal
AJAX reload (template type switch, modality switch, reset) on the
diagnosis/discharge/document print template settings pages
- diagnosis_print_settings.php: fix corrupted watermark_alpha number
input (missing step attribute) that silently blocked form submission
for templates with non-integer-step legacy values
