Summary

Implement phased HCL loading that achieves 4.6x faster server startup, 21x faster list commands, and 79% memory reduction while maintaining identical output to eager loading.

The Problem

Large mods (like AWS compliance with 800+ files) took ~2.7 seconds to start the dashboard server because we parsed and resolved ALL HCL files upfront. List commands also suffered from this overhead.

The Solution

Three-phase loading that separates fast metadata extraction from slow reference resolution:

  1. Phase 1 (Index Build): Parse HCL syntax, extract literal metadata (~500ms)
  2. Phase 2 (Background Resolution): Resolve variables/templates asynchronously
  3. Phase 3 (On-Demand): Full resource loading when user interacts

Performance Results

Tested with aws-compliance mod (512 files, 3091 benchmarks/controls):

Metric Eager Lazy/Phased Improvement
Server Startup 2,658ms 575ms 4.6x faster
Memory at Startup 333MB 71MB 79% reduction
benchmark list 1,800ms 84ms 21x faster
dashboard list ~1,800ms ~80ms ~22x faster

Key Insight

HCL syntax parsing is fast. The slowness comes from multi-pass reference resolution. We can extract literal metadata (tags, titles, descriptions) WITHOUT triggering resolution - this is what makes Phase 1 fast.

Changes

List Commands (internal/display/list_resources.go)

  • benchmark list, control list, dashboard list, query list, detection list now use lazy loading
  • variable list and mod list still use eager loading (need resolved values)
  • All show commands use eager loading to ensure complete output with all metadata fields

ListableIndexEntry (internal/display/listable_index_entry.go)

  • New wrapper to display index entries without loading full resources
  • Implements printers.Listable interface for seamless integration
  • Custom JSON marshaling for consistent output format

Enhanced IndexEntry (internal/resourceindex/entry.go)

  • New metadata fields: Category, Documentation, Display, Width
  • Resolution tracking: TitleResolved, DescriptionResolved, TagsResolved
  • Helper methods: NeedsResolution(), IsFullyResolved()

Enhanced Scanner (internal/resourceindex/scanner.go)

  • extractStringWithResolution(): Track if value is literal or needs resolution
  • extractTagsComplete(): Handle literal, variable, and merge() tag patterns
  • Extract inline literals from merge() calls (e.g., tags = merge(var.x, {service = "AWS"}))

Background Resolver (internal/workspace/background_resolver.go)

  • Priority queue (top-level dashboards resolved first)
  • Configurable worker goroutines
  • Graceful shutdown with context cancellation
  • On-demand ResolveNow() for immediate resolution

Dashboard Server (internal/dashboardserver/payload.go)

  • Index-based payload builder uses enhanced IndexEntry
  • Full metadata (tags, titles, descriptions) displayed from index
  • JSON output identical to eager loading

Test Infrastructure (tests/acceptance/run-local.sh)

  • Disable version update checks (POWERPIPE_UPDATE_CHECK=false) to prevent stdout pollution in tests

Test Coverage

Category Tests Description
CLI Acceptance 23 BATS check.bats - benchmark/control execution
Show Output 14 BATS resource_show_outputs.bats - all resource types
Mod Tests 96 BATS mod.bats - install/update scenarios

Add a new timing package to enable performance measurement of mod loading
and server startup. Key changes:

- Create internal/timing package with Track, Report, and ReportJSON functions
- Add timing instrumentation to workspace loading (Load, LoadWorkspaceMod, etc.)
- Add timing instrumentation to initialization (NewInitData, Init, db client)
- Add timing instrumentation to dashboard server startup
- Add timing instrumentation to payload building functions
- Add overall startup timing and report output in server command

Timing is controlled via environment variable:
- POWERPIPE_TIMING=1 - Enable timing with summary report
- POWERPIPE_TIMING=detailed - Output each measurement as it happens
- POWERPIPE_TIMING=json - Output JSON format for programmatic parsing

No performance impact when timing is disabled.

Run database client creation in parallel with telemetry init and mod
installation to reduce blocking time during server startup.

Changes:
- Add clientResult struct to hold async database client creation result
- Refactor Init() to start DB client creation in a goroutine immediately
- telemetry.Init and modinstaller run concurrently with DB client creation
- Add proper synchronization to wait for DB client before validation
- Add error handling and cleanup if mod installation fails

Performance improvement is most significant with slow/remote databases
where connection time can be 200-500ms.

Implement lazy loading of mod resources to reduce memory usage and
improve startup time for the dashboard server. Resources are loaded
on-demand when accessed rather than all at startup.

Key components:
- ResourceIndex: Fast metadata index of all resources without full parse
- ResourceCache: LRU cache for parsed resources with memory limits
- Loader: On-demand resource parser with HCL decoding
- DependencyResolver: Resolves and loads resource dependencies
- LazyWorkspace: Workspace implementation using lazy loading
- LazyModResources: Lazy accessor for mod resources

Features:
- --lazy-load flag for powerpipe server command
- POWERPIPE_LAZY_LOAD environment variable
- Nested block decoding for inline dashboard children
- Mod name mapping for cross-mod query references
- Improved server error handling for port conflicts

Dashboard server integration:
- Serves available_dashboards from index (no resource loading)
- Loads dashboard trees on-demand when selected
- Supports both eager and lazy workspace modes

Tests:
- Resource index tests
- Cache tests with LRU eviction
- Loader and resolver tests
- Workspace behavior tests
- Server integration tests

The hybrid approach uses lazy loading for fast startup and browsing
(dashboard list), but switches to eager/full HCL parsing when executing
benchmarks to ensure reliable execution with properly resolved query
references.

Key changes:
- Add GetWorkspaceForExecution() to LazyWorkspace that loads the full
  workspace on first execution request and caches it
- Copy event handlers from lazy workspace to eager workspace so
  execution events properly route to the server
- Update select_dashboard handler to fetch resources from the eager
  workspace, ensuring query references are resolved
- Update all getWorkspaceForExecution call sites to handle errors

This fixes the "failed to resolve query" error that occurred when
controls referenced queries in lazy mode, while maintaining fast
startup for browsing.

Remove the regex-based scanner implementation and delegate all scanning
to the HCL syntax parser. This simplifies the codebase from ~800 lines
to ~270 lines while ensuring correct handling of all HCL edge cases.

Changes:
- ScanFile(), ScanFileWithOffsets(), ScanBytes() now delegate to HCL
- Remove regex patterns and state machine code
- Update tests for HCL parser behavior (proper string unescaping)

Performance: ~14ms for 1000 resources (18x faster than full parse)

This commit implements a comprehensive phased loading system that achieves
fast server startup while maintaining complete metadata display (tags,
titles, descriptions) - identical to eager loading.

## Performance Results

| Metric | Eager | Phased | Improvement |
|--------|-------|--------|-------------|
| Server Startup | 2658ms | 575ms | 4.6x faster |
| Memory at Startup | 333MB | 71MB | 79% reduction |
| Dashboard List | - | 20ms | - |

## Architecture: Three-Phase Loading

### Phase 1: Index Build (Immediate, ~500ms)
- Parse ALL HCL files syntactically
- Extract literal metadata (tags, title, description, category)
- NO reference resolution - this is what makes it fast
- Dashboard list is immediately complete with full metadata

### Phase 2: Background Resolution (Async)
- Priority queue resolves top-level resources first
- Worker goroutines resolve variable references, templates
- Index entries updated progressively
- UI notified via callbacks when updates available

### Phase 3: On-Demand Loading (User Interaction)
- Full HCL parsing when user clicks dashboard/benchmark
- Reference resolution for execution
- Results cached in ResourceCache

## Key Changes

### Enhanced IndexEntry (internal/resourceindex/entry.go)
- New metadata fields: Category, Documentation, Display, Width
- Resolution tracking: TitleResolved, DescriptionResolved, TagsResolved
- Helper methods: NeedsResolution(), IsFullyResolved()

### Enhanced Scanner (internal/resourceindex/scanner_hcl.go)
- extractStringWithResolution(): Track if value is literal or needs resolution
- extractTagsComplete(): Handle literal, variable, merge() tag patterns
- Extract inline literals from merge() calls

### Background Resolver (internal/workspace/background_resolver.go)
- Priority queue with configurable workers
- Graceful shutdown with context cancellation
- On-demand ResolveNow() for immediate resolution
- Stats reporting for monitoring

### Dashboard Server Integration (internal/dashboardserver/payload.go)
- Index-based payload builder uses enhanced IndexEntry
- Full metadata displayed from index (no eager load needed)
- JSON output identical to eager loading

## Test Coverage

- 22 BATS acceptance tests for CLI commands
- 40+ scanner unit tests for metadata extraction
- 20+ concurrent access tests with race detector
- 25+ error handling tests
- 60+ cross-mod reference tests
- Browser UI tests verified manually

## Configuration

POWERPIPE_WORKSPACE_PRELOAD=true forces eager loading for debugging.

The on-demand resource loader was generating anonymous block names using
a different pattern (e.g., "container_1") than the pipe-fittings eager
loader (e.g., "dashboard_name_anonymous_container_0"). This caused panel
name mismatches between eager and lazy loading during dashboard execution.

Changed the naming in decodeNestedBlocks() to match pipe-fittings:
- Format: {sanitised_parent_name}_anonymous_{block_type}_{index}
- Uses 0-based indexing (increment after name generation)
- Replaces dots with underscores in parent name

Also removes the POWERPIPE_WORKSPACE_PRELOAD=true workaround from CI
acceptance tests since the root cause is now fixed.

- Add directory existence validation in listPowerpipeFiles()

This reduces code duplication between eager and lazy loading paths,
preventing semantic drift that could cause panel name mismatches.

This commit fixes several issues with lazy loading that were causing
CI test failures:

1. phased_loading_comparison.bats: Added sort_json_by_name helper to
   handle non-deterministic JSON array ordering in benchmark list output

2. phased_loading_cli.bats: Added strip_update_banner helper to filter
   out intermittent powerpipe update notifications from plain/pretty output

3. dashboard_parsing_validation.bats: Updated error message patterns
   to match the new validation output format

4. dashboard.bats: Fixed multiple issues:
   - Added BlockTypeWith to isDashboardChildType() for proper 'with' block handling
   - Added OnDecoded calls for resources and child resources
   - Implemented resolveBaseReference() to handle 'base' attribute references
   - Added extractRuntimeDependencies() to extract runtime dependencies from
     args attribute for child resources
   - Added InitInputs() call for dashboards to populate selfInputsMap

The key changes in parser.go:
- extractRuntimeDependencies(): New function that calls DecodeArgs to extract
  runtime dependencies from the args attribute and add them to QueryProvider
  resources. This is needed because DecodeHclBody doesn't extract these.
- resolveBaseReference(): Handles 'base = node.xxx' style references by
  loading the referenced resource and setting it on the current resource
- decodeNestedBlocks(): Now calls extractRuntimeDependencies after decoding
- decodeNodeAndEdgeBlocks(): Also calls extractRuntimeDependencies
- parseResource(): Now calls dashboard.InitInputs() after decoding nested
  blocks to initialize the selfInputsMap needed for runtime dependency resolution

Replace type-switch based resolveBaseReference() with loadBaseResourcesIntoEvalContext()
which pre-loads base resources into the HCL eval context before decoding. This allows
the HCL decoder to resolve base references naturally via the hcl:"base" tag, matching
eager loading behavior.

Key changes:
- Load base resources into eval context BEFORE DecodeHclBody call
- Add OnDecoded call in decodeNodeAndEdgeBlocks to trigger SetBaseProperties()
- Remove manual type-specific base assignment logic

This ensures lazy loading produces identical output to eager loading for all
resource types with base references (nodes, edges, charts, cards, tables, inputs).

- Add ListableIndexEntry wrapper to display index entries without full
  resource loading
- Modify ListResources to use lazy loading for benchmark, control,
  dashboard, query, and detection list commands
- Variables and Mods still use eager loading (need resolved values)
- Show commands use eager loading to ensure complete output with all
  metadata fields (nested dashboard components aren't indexed)
- Disable version update checks in acceptance tests to prevent stdout
  pollution

Performance improvement for `benchmark list` on aws-compliance mod:
- Before: ~1.8s (eager loading)
- After: ~0.08s (lazy loading via index)

Add resource_name field (short name) to ListableIndexEntry JSON marshaling
to match the expected output format. Tests were expecting both qualified_name
and resource_name fields but only qualified_name was being output.

Replace hardcoded external mod path with self-contained test mods from
the repo. Benchmarks now use internal/testdata/mods/generated/medium by
default, while still allowing BENCHMARK_MOD_PATH override for local
testing with larger mods.

- Add auto_generated, path, url_path fields to ListableIndexEntry JSON
- Add source_definition by reading from file using byte offsets
- Add anonymous children scanning for dashboards (container, card, etc.)
- Add Reference struct and capture benchmark children references
- Generate resource_name hash matching pipe-fittings MD5 format
- Build hierarchical path including parent for nested resources

All phased_loading_comparison acceptance tests now pass.
Benchmarks confirm no performance regression (12x speedup maintained).

MD5 is used to match the hash format from pipe-fittings, not for security.

- Add SQL field extraction and args output for controls
- Compute full hierarchical paths (mod -> parent -> child) instead of
  just immediate parent
- Track multiple parents for controls that belong to multiple benchmarks
- Add cycle detection to path computation to prevent infinite recursion
- Pre-compute paths during scanning for JSON output consistency

…nresolved tags

When list command detects entries with unresolved variable references
(like tags = local.common_tags), wait up to 5 seconds for background
resolution to complete before displaying results. This ensures variable
tags are properly resolved in lazy loading mode.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Background resolution was never started because StartBackgroundResolution
was not called from LoadLazy. This meant variable tags would never be
resolved in lazy mode.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Tags that reference locals/variables (e.g., tags = local.common_tags)
cannot be resolved in lazy mode because it avoids full HCL evaluation
for fast startup. This is an acceptable tradeoff since most production
mods use literal tags.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Support the common pattern of tags = local.common_tags in lazy loading mode
by building an HCL eval context with variables and locals at workspace init.

Key changes:
- Add eval_context.go with optimized variable/locals extraction
- Use fast byte-level pre-scan to filter files before HCL parsing
- Only files containing 'variable ' or 'locals' keywords are parsed
- Store eval context in Loader and use it when decoding resources

Performance (steampipe-mod-aws-compliance, 70K lines):
- Eager loading: ~1900ms
- Lazy loading: ~260ms (~7.5x faster)
- Eval context build: ~143ms (optimized from ~345ms via pre-scan)

Re-enables test 14 in phased_loading_cli.bats which was previously skipped.

…ication

- Change ListableIndexEntry.GetListData() to always use full qualified name
  (mod.type.name) instead of short names for local resources
- Add 8 new tests to verify full qualified name format in list commands:
  - NAME column format tests for dashboard, benchmark, and control list
  - JSON qualified_name field format tests
  - Integration tests verifying show commands work with list output names

This ensures backward compatibility with v1.4.2 output format while
maintaining lazy loading performance improvements.

When lazy loading is enabled but the scanner finds no dashboards or
benchmarks in the index, automatically fall back to eager loading.
This fixes the "No dashboards" issue in Pipes where mod resources
may be provided through a mechanism that doesn't make local .pp/.sp
files accessible to the lazy loading scanner.
