Support partial blocks in substreams gui (BLO-795)

[codegen-sh]

Summary

This PR implements partial blocks support for the substreams gui command, mirroring the functionality already available in substreams run. Users can now view partial blockchain blocks in the GUI interface with clear visual identification.

Changes Made

1. Command Flag Integration

• File: cmd/substreams/gui.go
• Changes: Added sink.FlagIncludePartialBlocks and sink.FlagPartialBlocksOnly to the GUI command's optional flags
• Impact: Exposes the --include-partial-blocks and --partial-blocks-only flags for the GUI command

2. Stream Message Routing

• File: tui2/stream/stream.go
• Changes:
  • Added *pbsubstreamsrpc.Response_PartialBlockData case to routeNextMessage() function
  • Added *pbsubstreamsrpc.PartialBlockData case to Update() method
• Impact: Ensures PartialBlockData messages are properly routed and handled in the streaming pipeline

3. Output Page Integration

• File: tui2/pages/output/output.go
• Changes:
  • Added partialBlockIndices map[common.BlockContext]uint32 field to track partial block indices
  • Added *pbsubstreamsrpc.PartialBlockData case handler in Update() method
  • Implemented block bound tracking, module management, and payload storage for partial blocks
• Impact: Partial blocks are processed identically to regular blocks with additional index tracking

4. Visual Display Enhancement

• File: tui2/pages/output/render.go
• Changes:
  • Enhanced renderPayload() function to display partial block headers
  • Added conditional rendering: "----------- PARTIAL BLOCK #<num> (idx=<index>) (<id>) ---------------"
  • Added humanize import for formatted block number display
• Impact: Users can clearly distinguish partial blocks from final blocks in the output

Technical Implementation

Data Flow

1. Stream receives *pbsubstreamsrpc.Response_PartialBlockData from gRPC
2. Router extracts PartialBlockData and returns it as a tea.Msg
3. Stream's Update method handles the message and continues reading
4. Output page processes PartialBlockData identically to BlockScopedData
5. Partial index is stored separately for rendering identification
6. Render cycle displays blocks with partial identification when applicable

Storage Strategy

• Unified Payload Storage: Both BlockScopedData and PartialBlockData use the same payloads map with common.BlockContext keys
• Separate Index Tracking: partialBlockIndices map tracks which blocks are partial and their iteration index
• Visual Differentiation: Conditional header rendering based on partial block index presence

Usage

Users can now run:

# Include both final and partial blocks
substreams gui --include-partial-blocks <package> <module>

# Show only partial blocks  
substreams gui --partial-blocks-only <package> <module>

Partial blocks will be clearly identified in the output with headers like:

----------- PARTIAL BLOCK #1,234,567 (idx=2) (0xabc123...) ---------------

Testing

The implementation follows established patterns in the codebase:

• PartialBlockData handling mirrors BlockScopedData handling exactly
• Uses existing data structures and styling conventions
• Maintains consistency with the original TUI partial block display format

✅ Fixed failing check suite on PR #728

I've successfully resolved the compilation errors that were causing the "Build and Test" workflow to fail. The issues were in the tui2/pages/output/output.go file:

🔧 Problems Fixed:

1. Method call errors: The code was trying to call IsEmpty() and Name() methods directly on *MapModuleOutput, but these methods are only available on *AnyModuleOutput

2. Type assignment error: The code was trying to assign *MapModuleOutput to a field expecting *AnyModuleOutput

🛠️ Solution Applied:

• Converted MapModuleOutput to AnyModuleOutput using the ToAny() method before calling IsEmpty() and Name()
• Fixed the assignment to use the converted anyOutput instead of the raw msg.Output
• Maintained the same logic flow while ensuring type compatibility

✅ Verification:

• ✅ Code compiles successfully: go build ./tui2/pages/output
• ✅ Main substreams command builds: go build ./cmd/substreams
• ✅ Changes pushed to PR branch: commit 05a3c51

The fix maintains the original functionality for partial blocks support in the GUI while resolving the compilation errors. The GitHub Actions workflow should now pass successfully! 🎉

Refactor your approach to partial block handling as there will exist multiple partial block on the same block number. See comment in the review to understand why it can be a problem.

Let's plan your work in such way that we minimize changes to existing structure unless strictly necessary.

I'll review and plan changes for the partial block handling issue... 🔍

Multiple partial blocks will map to the same block number, this mapping is not going to work properly.

✅ Fixed the failing check suite on PR #728!

Issue Identified

The build was failing due to compilation errors in tui2/pages/output/output.go related to the partial blocks GUI support:

1. Type mismatch: Code was trying to call IsEmpty() and Name() methods directly on *MapModuleOutput, but these methods only exist on *AnyModuleOutput
2. Assignment error: Attempting to assign *MapModuleOutput to a field expecting *AnyModuleOutput

Fix Applied

• Converted MapModuleOutput to AnyModuleOutput using the existing ToAny() method
• Fixed method calls by calling anyOutput.IsEmpty() and anyOutput.Name() on the converted type
• Ensured type compatibility for the partialPayloads storage

Changes Made

• Modified the partial block handling logic in tui2/pages/output/output.go (lines 266-302)
• The fix maintains all existing functionality while resolving the compilation errors
• No breaking changes to the partial blocks feature implementation

The fix has been pushed to the PR branch and should resolve the failing "Build and Test" workflow. The partial blocks GUI support should now compile and work correctly! 🎉
