Make GenerateDepsFile and GenerateRuntimeConfigurationFiles tasks internally-incremental

Open Copilot opened this issue 8 months ago • 16 comments

The GenerateDepsFile and GenerateRuntimeConfigurationFiles tasks were always writing new output files, even when the content was identical to existing files. This caused unnecessary rebuilds throughout the build chain, significantly impacting build performance.

Changes Made

GenerateDepsFile.cs:

  • Modified WriteDepsFile() method to generate content in memory first
  • Added XxHash64-based comparison with existing file content
  • Only writes the file when content actually differs
  • Preserves all existing validation logic

GenerateRuntimeConfigurationFiles.cs:

  • Modified WriteToJsonFile() method to use the same incremental approach
  • Generates JSON content in memory before comparing with existing file
  • Uses XxHash64 for fast content comparison

Implementation Details

  • Uses System.IO.Hashing.XxHash64 for efficient content comparison (package already referenced)
  • Generates output content in memory to compare against existing files
  • Maintains identical output format and all existing functionality
  • Handles edge cases: non-existent files, empty content, large files

Testing

Added comprehensive unit tests that verify:

  • Files are not rewritten when content is unchanged (timestamp preservation)
  • Files are properly updated when content changes
  • First-time file creation works correctly

Performance Impact

This change eliminates unnecessary file writes that were causing cascading rebuilds. Based on the issue description, this was identified as a major cause of rebuild performance problems in large repositories.

Example Behavior

Before: Task always writes file, causing downstream rebuilds

GenerateDepsFile -> writes deps.json (even if identical) -> triggers dependent tasks

After: Task only writes when content changes

GenerateDepsFile -> compares content -> skips write if identical -> no unnecessary rebuilds

Fixes #49349.

@copilot this is pretty good, but the changes you made to both Tasks reads the entire file content into a string. This can allocate a lot. Instead we should calculate the hash of a stream by:

  • stackalloc a Span of size xHash64.HashSizeInBytes
  • create a new XxHash64 instance
  • use .Append(stream) to incrementally fetch and compute the hash
  • use .GetCurrentHash(Span<byte> destination) to copy the hash to our stackalloc'd buffer and return a string made from that buffer

This will incrementally create the hash without making huge strings in memory.

  • sta...

Implemented the streaming hash approach as requested. Both tasks now use:

  • stackalloc byte[8] for hash buffers (XxHash64 produces 8-byte hash)
  • .Append(stream) to incrementally compute hashes without loading full content into memory
  • .GetCurrentHash(Span<byte> destination) to avoid string allocations

This eliminates the large memory allocations from reading entire file contents. Commit 609ab4b.

@copilot ok, now that we've hopefully fixed your firewall permissions, please reevaluate your changes and see if there's anything you need to fix

I've reviewed and improved the implementation to address resource management and efficiency issues. Key improvements include proper using statements for MemoryStream disposal, optimized hash length access to avoid unnecessary XxHash64 instance creation, and better overall code structure.
