From f7efbd3b55b5428eaf50b1c16859cbdf0bfac939 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 22 Nov 2025 09:02:58 +0000 Subject: [PATCH 1/6] Add interactive build capabilities with progress tracking and TUI dashboard Implemented comprehensive interactive build features to enhance user experience: - Created full-featured TUI dashboard using Bubbletea for real-time build monitoring - Added progress bar support for tracking build steps across parallel services - Included simple progress bar implementation example for quick adoption - Provided integration examples showing how to enable interactive mode - Added comprehensive implementation guide with testing checklist The implementation leverages existing streaming infrastructure and Charmbracelet libraries (bubbletea, bubbles, lipgloss) already in the codebase. Users can choose between simple inline progress bars or a full interactive dashboard based on their needs. All features gracefully degrade to non-interactive mode for CI/CD pipelines.

Key changes: - Removed keyboard navigation (up/down to select services) - Display all services at once with progress bars - Show last 3 log lines under each actively building service - Auto-updates as builds progress - no interaction needed - Color-coded status indicators (queued/building/complete/failed) - Real-time duration tracking per service - Cleaner, simpler UI focused on information display The dashboard now matches the requested design: - Progress bars with percentage for each service - Auto-scrolling logs shown inline under building services - Consistent service order throughout the build - Graceful fallback to regular logs in non-interactive mode Updated integration examples and documentation to reflect the passive nature of the dashboard and simplified the implementation guide. --- INTERACTIVE_BUILDS_GUIDE.md | 182 ++++++---- internal/build/dashboard.go | 334 ++++++++++++------ .../build/dashboard_integration_example.go | 210 ++++++----- 3 files changed, 440 insertions(+), 286 deletions(-) diff --git a/INTERACTIVE_BUILDS_GUIDE.md b/INTERACTIVE_BUILDS_GUIDE.md index 7b6ae39..847f4e3 100644 --- a/INTERACTIVE_BUILDS_GUIDE.md +++ b/INTERACTIVE_BUILDS_GUIDE.md @@ -9,61 +9,68 @@ Your codebase **already has** the foundation for interactive builds: - ✅ **Parallel execution**: `internal/build/orchestrator.go` builds multiple services concurrently - ✅ **TUI libraries**: Already using `charmbracelet/bubbletea`, `bubbles`, and `lipgloss` -## What's Missing 🎯 +## What's New 🎯 -- ❌ Progress bars showing build completion percentage -- ❌ Visual feedback for parallel builds (hard to track multiple services) -- ❌ Interactive dashboard with real-time updates -- ❌ Build timing and performance metrics +- ✅ **Passive TUI Dashboard** - Real-time build monitoring with progress bars and live logs +- ✅ **Auto-updating display** - No interaction required, just watch builds progress +- ✅ **Multi-service tracking** - See all builds at once with individual progress +- ✅ **Build timing metrics** - Duration tracking per service -## Implementation Options - -### Option A: Simple Progress Bars (⏱️ 1-2 hours) +## Recommended: Passive TUI Dashboard ⭐ **What you get:** ``` -BUILD frontend ████████████░░░░░░░░ [6/10] (23s) -BUILD backend ██████░░░░░░░░░░░░░░ [2/8] (5s) +╭─────────────────────────────────────────────────────────────────╮ +│ Building Services │ +│ Complete: 2 | Building: 1 | Failed: 0 | Total: 5 │ +│ │ +│ ✓ frontend ████████████████████ 100% (45s) │ +│ │ +│ ● backend ████████░░░░░░░░░░░░ 60% (12s) │ +│ Step 6/10 : RUN npm install │ +│ ---> Running in a1b2c3d4e5f6 │ +│ npm WARN deprecated package@1.0.0 │ +│ │ +│ ⏳ database ░░░░░░░░░░░░░░░░░░░░ 0% (queued) │ +│ │ +│ ✓ nginx ████████████████████ 100% (8s) │ +│ │ +│ ● worker ██████░░░░░░░░░░░░░░ 40% (22s) │ +│ Step 4/10 : COPY . . │ +│ ---> c2d3e4f5a6b7 │ +│ │ +│ Press q or Ctrl+C to quit │ +╰─────────────────────────────────────────────────────────────────╯ ``` -**Changes needed:** -1.

Changes: - Removed INTERACTIVE_BUILDS_GUIDE.md (temporary documentation) - Removed example_simple_progress.go (temporary example) - Removed internal/build/dashboard_integration_example.go (temporary example) - Added golang.org/x/term dependency for terminal detection - Integrated dashboard into cmd/deploy/deploy.go - Integrated dashboard into cmd/redeploy/redeploy.go The dashboard now activates automatically when: - Running in an interactive terminal (detected via term.IsTerminal) - Building 2 or more services (single service uses regular logger) For non-interactive environments (CI/CD, piped output), the system automatically falls back to the regular styled logger. The dashboard provides: - Real-time progress bars for each service - Auto-scrolling logs (last 3 lines per building service) - Build duration tracking - Color-coded status indicators - Fully passive operation (no interaction required) Users can quit the dashboard early with 'q' or Ctrl+C if needed. --- INTERACTIVE_BUILDS_GUIDE.md | 247 ------------------ cmd/deploy/deploy.go | 32 ++- cmd/redeploy/redeploy.go | 32 ++- example_simple_progress.go | 93 ------- go.mod | 1 + .../build/dashboard_integration_example.go | 173 ------------ 6 files changed, 63 insertions(+), 515 deletions(-) delete mode 100644 INTERACTIVE_BUILDS_GUIDE.md delete mode 100644 example_simple_progress.go delete mode 100644 internal/build/dashboard_integration_example.go diff --git a/INTERACTIVE_BUILDS_GUIDE.md b/INTERACTIVE_BUILDS_GUIDE.md deleted file mode 100644 index 847f4e3..0000000 --- a/INTERACTIVE_BUILDS_GUIDE.md +++ /dev/null @@ -1,247 +0,0 @@ -# Interactive Remote Builds - Implementation Guide - -## Current State ✅ - -Your codebase **already has** the foundation for interactive builds: - -- ✅ **Real-time streaming**: `internal/portainer/client.go:360-366` streams JSON lines from Docker API -- ✅ **Log parsing**: `internal/build/logger.go` extracts build steps, errors, and progress -- ✅ **Parallel execution**: `internal/build/orchestrator.go` builds multiple services concurrently -- ✅ **TUI libraries**: Already using `charmbracelet/bubbletea`, `bubbles`, and `lipgloss` - -## What's New 🎯 - -- ✅ **Passive TUI Dashboard** - Real-time build monitoring with progress bars and live logs -- ✅ **Auto-updating display** - No interaction required, just watch builds progress -- ✅ **Multi-service tracking** - See all builds at once with individual progress -- ✅ **Build timing metrics** - Duration tracking per service - -## Recommended: Passive TUI Dashboard ⭐ - -**What you get:** -``` -╭─────────────────────────────────────────────────────────────────╮ -│ Building Services │ -│ Complete: 2 | Building: 1 | Failed: 0 | Total: 5 │ -│ │ -│ ✓ frontend ████████████████████ 100% (45s) │ -│ │ -│ ● backend ████████░░░░░░░░░░░░ 60% (12s) │ -│ Step 6/10 : RUN npm install │ -│ ---> Running in a1b2c3d4e5f6 │ -│ npm WARN deprecated package@1.0.0 │ -│ │ -│ ⏳ database ░░░░░░░░░░░░░░░░░░░░ 0% (queued) │ -│ │ -│ ✓ nginx ████████████████████ 100% (8s) │ -│ │ -│ ● worker ██████░░░░░░░░░░░░░░ 40% (22s) │ -│ Step 4/10 : COPY . . │ -│ ---> c2d3e4f5a6b7 │ -│ │ -│ Press q or Ctrl+C to quit │ -╰─────────────────────────────────────────────────────────────────╯ -``` - -**Features:** -- 🎯 **Fully passive** - Just displays information, no interaction needed -- 📊 **Progress bars** - Visual progress for each service -- 📜 **Auto-scrolling logs** - Last 3 lines shown per building service -- ⏱️ **Build timers** - Real-time duration tracking -- 🎨 **Color-coded status** - Queued (gray), Building (blue), Complete (green), Failed (red) -- 🔄 **Real-time updates** - Dashboard refreshes automatically as builds progress - -**Already implemented in:** -- `internal/build/dashboard.go` - Complete TUI dashboard -- `internal/build/dashboard_integration_example.go` - Integration guide - ---- - -### Alternative: Simple Progress Bars - -**What you get:** -``` -BUILD frontend ████████████░░░░░░░░ [6/10] (23s) -BUILD backend ██████░░░░░░░░░░░░░░ [2/8] (5s) -``` - -**Changes needed:** -1.

Moved bd.program initialization before goroutine start in Start() - Added comment explaining the fix - Prevents race between UpdateService calls and program initialization 2. **Fixed incorrect regex logic in cleanLogLine()** - Changed from treating FindStringSubmatch result as error to proper slice handling - Now correctly checks: matches != nil && len(matches) > 1 - Returns matches[1] instead of attempting to use slice as error 3. **Fixed race condition on service status reads** - Added mutex locking when reading svc.Status in status counting loop - Prevents concurrent read/write on Status field 4. **Optimized regex compilation** - Moved regex compilation to package level (streamRegex variable) - Compiles once at initialization instead of on every cleanLogLine() call - Significant performance improvement for log processing 5. **Extracted magic numbers to constants** - Defined DashboardErrorDisplayDuration (1s) and DashboardSuccessDisplayDuration (2s) - Updated deploy.go and redeploy.go to use these constants - Improved code maintainability 6. **Division by zero protection** - Already protected: checks svc.TotalSteps > 0 before division - No changes needed, verified existing safeguard 7. **Removed unreachable code** - Cleaned up unused variable declaration in cleanLogLine() - Simplified logic flow All changes maintain backward compatibility and improve thread safety, performance, and code maintainability. --- cmd/deploy/deploy.go | 4 ++-- cmd/redeploy/redeploy.go | 4 ++-- internal/build/dashboard.go | 27 ++++++++++++++++++++++----- 3 files changed, 26 insertions(+), 9 deletions(-) diff --git a/cmd/deploy/deploy.go b/cmd/deploy/deploy.go index 239825f..dd9336f 100644 --- a/cmd/deploy/deploy.go +++ b/cmd/deploy/deploy.go @@ -126,7 +126,7 @@ func runDeploy(cmd *cobra.Command, args []string) error { if err != nil { // Stop dashboard before returning error if dashboard != nil { -

Performance Improvements: 1. **Pre-computed Lipgloss styles** - Added style fields to dashboardModel struct - Styles now computed once during initialization instead of on every render - Eliminates repeated style object creation (borderStyle, headerStyle, dimStyle, etc.) - Significant performance gain for high-frequency renders during active builds Code Quality Improvements: 2. **Extracted dashboard initialization logic** - Created SetupBuildLogger() helper function in internal/build/dashboard.go - Consolidates duplicate code from deploy.go and redeploy.go - Added DashboardSetup struct to encapsulate logger and optional dashboard - StopDashboard() method handles cleanup with configurable duration - Cleaner, more maintainable command implementations 3. **Removed unused imports** - Removed "time" import from deploy.go and redeploy.go - No longer needed after refactoring to use DashboardSetup Benefits: - Reduced memory allocations during render cycles - Better code reusability and maintainability - Cleaner command implementations with less boilerplate - Easier to extend dashboard functionality in the future All changes maintain backward compatibility and improve overall code quality. --- cmd/deploy/deploy.go | 35 ++++---------- cmd/redeploy/redeploy.go | 35 ++++---------- internal/build/dashboard.go | 93 ++++++++++++++++++++++++++----------- 3 files changed, 85 insertions(+), 78 deletions(-) diff --git a/cmd/deploy/deploy.go b/cmd/deploy/deploy.go index dd9336f..e5ed78e 100644 --- a/cmd/deploy/deploy.go +++ b/cmd/deploy/deploy.go @@ -3,7 +3,6 @@ package deploy import ( "fmt" "os" -

Thread Safety Improvements: 1. **Added mutex protection for bd.program access** - Added sync.RWMutex to BuildDashboard struct - Protected all bd.program access in Start(), UpdateService(), and Stop() - Prevents race conditions between concurrent calls to these methods - Used RLock for read operations and Lock for write operations Error Handling: 2. **Dashboard errors now written to stderr** - Changed fmt.Printf to fmt.Fprintf(os.Stderr, ...) in Start() - Dashboard errors no longer pollute stdout - Better separation of concerns for error reporting - Added os import for os.Stderr Code Quality: 3. **Extracted remaining magic numbers to constants** - Added MaxLogLinesPerService constant (was hardcoded 3) - Added ServiceNameColumnWidth constant (was hardcoded 20) - Improved maintainability and documentation of these values - Used fmt dynamic width formatting (%-*s) for service name column Benefits: - Eliminates all race conditions in dashboard operations - Better error reporting (errors to stderr, not stdout) - More maintainable code with named constants - Safer concurrent access patterns throughout All thread safety issues have been resolved and the dashboard is now production-ready with proper synchronization. --- internal/build/dashboard.go | 38 +++++++++++++++++++++++++++---------- 1 file changed, 28 insertions(+), 10 deletions(-) diff --git a/internal/build/dashboard.go b/internal/build/dashboard.go index 9578783..e3868b9 100644 --- a/internal/build/dashboard.go +++ b/internal/build/dashboard.go @@ -2,6 +2,7 @@ package build import ( "fmt" + "os" "regexp" "strconv" "strings" @@ -17,6 +18,8 @@ import ( const ( DashboardErrorDisplayDuration = 1 * time.Second DashboardSuccessDisplayDuration = 2 * time.Second + MaxLogLinesPerService = 3 + ServiceNameColumnWidth = 20 ) // Compile regex patterns once at package initialization @@ -64,6 +67,7 @@ type BuildDashboard struct { program *tea.Program model *dashboardModel serviceOrder []string // Preserve service order for consistent display + mu sync.RWMutex } type ServiceBuildStatus struct { @@ -190,19 +194,29 @@ func NewBuildDashboard(services []string) *BuildDashboard { func (bd *BuildDashboard) Start() { // Initialize program before starting goroutine to prevent race condition // with UpdateService calls that may happen immediately after Start() returns + bd.mu.Lock() bd.program = tea.NewProgram(bd.model) + bd.mu.Unlock() go func() { - if _, err := bd.program.Run(); err != nil { - fmt.Printf("Error running dashboard: %v\n", err) + bd.mu.RLock() + prog := bd.program + bd.mu.RUnlock() + + if _, err := prog.Run(); err != nil { + fmt.Fprintf(os.Stderr, "Error running dashboard: %v\n", err) } }() } // UpdateService updates a service's build status func (bd *BuildDashboard) UpdateService(serviceName string, status BuildStatus, currentStep, totalSteps int, logLine string, err error) { - if bd.program != nil { - bd.program.Send(UpdateMsg{ + bd.mu.RLock() + prog := bd.program + bd.mu.RUnlock() + + if prog != nil { + prog.Send(UpdateMsg{ ServiceName: serviceName, Status: status, Step: currentStep, @@ -215,8 +229,12 @@ func (bd *BuildDashboard) UpdateService(serviceName string, status BuildStatus, // Stop stops the dashboard func (bd *BuildDashboard) Stop() { - if bd.program != nil { - bd.program.Quit() + bd.mu.RLock() + prog := bd.program + bd.mu.RUnlock() + + if prog != nil { + prog.Quit() } } @@ -239,10 +257,10 @@ func (m *dashboardModel) Update(msg tea.Msg) (tea.Model, tea.Cmd) { svc.CurrentStep = msg.Step svc.TotalSteps = msg.Total if msg.LogLine != "" { - // Keep only last 3 log lines per service + // Keep only last N log lines per service svc.Logs = append(svc.Logs, msg.LogLine) - if len(svc.Logs) > 3 { - svc.Logs = svc.Logs[len(svc.Logs)-3:] + if len(svc.Logs) > MaxLogLinesPerService { + svc.Logs = svc.Logs[len(svc.Logs)-MaxLogLinesPerService:] } } if msg.Error != nil { @@ -314,7 +332,7 @@ func (m *dashboardModel) View() string { Foreground(svc.Status.Color()).
