src/pipelines/fill_mask_pipeline/builder.rs (1)
9-37: Well-executed architectural improvementThis refactoring demonstrates good software engineering practices by:
- Reducing code duplication across multiple pipeline builders
- Maintaining a consistent pattern throughout the codebase
- Preserving the public API while simplifying the implementation
The direct implementation on
StandardPipelineBuildereliminates unnecessary indirection and makes the code more straightforward.src/pipelines/text_generation_pipeline/parser.rs (1)
336-367: Consider extracting common top-level content emission logic.There's duplication between
emit_incremental_top_level_contentand theflushmethod for top-level content handling. Both follow similar patterns for newline trimming and event emission.Consider extracting a helper method to reduce duplication:
+ /// Helper to emit top-level content with consistent formatting + fn emit_top_level_content_slice( + &self, + state: &mut ParserState, + slice: &str, + is_first: bool, + ) -> Vec<Event> { + let mut events = Vec::new(); + + // Strip leading newlines if first emission + let content = if is_first { + slice.trim_start_matches('\n') + } else { + slice + }; + + let content_to_emit = if content.trim().is_empty() { + String::new() + } else { + content.to_string() + }; + + if !content_to_emit.is_empty() { + if !state.top_level_open { + events.push(Event::plain_start()); + state.top_level_open = true; + } + events.push(Event::content(content_to_emit.clone())); + state.last_content_had_newline = content_to_emit.ends_with('\n'); + } + + events + }Also applies to: 591-617

1-211: Fix markdown heading formatting issues.The static analysis correctly identifies trailing colons in headings which violate markdown best practices.
Apply this diff to fix the heading formatting:
-### Severity: **HIGH** -### Examples Found: +### Severity: **HIGH** +### Examples FoundThis pattern should be applied to all heading lines ending with colons (lines 11, 26, 36, 49, 58, 71, 80, 94, 103, 116, 125, 139, 148, 162, 171, 184, 192, 197, 202, 207).
src/models/components/common_layers.rs (1)
343-408: Comprehensive attention implementation with all standard features.The forward pass correctly implements multi-head attention with KV caching, optional QK normalization, and GQA support. The implementation is feature-complete and follows best practices.
Consider adding a comment about the sliding window feature for future implementers:
// Apply attention mask if provided + // Note: sliding_window_size is stored but not currently applied in masking let scores = if let Some(mask) = attention_mask {

151-198: Well-structured tag classification system!The introduction of
TagTypeenum andTagInfostruct provides excellent encapsulation and makes the tag parsing logic much cleaner. Theparsemethod handles all tag variants correctly with proper edge case handling.

TagInfo::parsewith pattern matching provides much cleaner control flow. The delegation to specific handler methods based on tag type and registration status is a significant improvement in code organization.
484-499: Proper sequencing of content emission.The logic to emit pending top-level content before starting a new tag ensures correct event ordering, which is crucial for streaming parsers.
521-545: Clean content normalization implementation.The method properly handles newline normalization with clear logic for first vs. subsequent emissions and ensures consistent trailing newline behavior.

73-101: Excellent adoption of standardized weight loading.The use of
WeightNaming::qwen3()andAttentionConfigstruct makes the weight loading more maintainable and consistent with other model implementations.
159-168: Verify the default dtype fallback logic.The current implementation defaults to
F32when the file type is not found or is not 2. This might lead to unexpected behavior if the file actually contains F16 weights.Consider logging a warning when falling back to the default dtype:
let dtype = metadata .get("general.file_type") .and_then(|v| v.to_u32().ok()) .map(|v| match v { 2 => DType::F32, _ => DType::F16, }) - .unwrap_or(DType::F32); + .unwrap_or_else(|| { + eprintln!("Warning: general.file_type not found, defaulting to F32"); + DType::F32 + });

151-198: Well-structured tag parsing with good separation of concerns.The
TagTypeenum andTagInfostruct provide clear classification of XML tags and encapsulate parsing logic effectively. Theparsemethod correctly handles all tag types with appropriate edge case handling.
313-324: Simplified token parsing with improved delegation.The refactored
parse_tokenmethod delegates incremental content emission to helper methods, improving code organization and maintainability.
396-432: Incremental tag content emission with proper newline handling.The
emit_incremental_tag_contentmethod correctly handles streaming tag content with appropriate newline trimming for first emissions. The logic accounts for already emitted content length to avoid duplication.
474-547: Excellent refactoring with clear separation of tag handling concerns.The refactored
handle_tagmethod and its specialized handlers (handle_closing_tag,handle_opening_tag,handle_unregistered_tag,handle_invalid_tag) provide much better modularity and readability compared to a monolithic approach.
549-587: Well-designed helper methods for content preparation.The
prepare_final_tag_contentandemit_pending_top_level_contentmethods provide clear abstractions for content handling with consistent newline normalization policies.
597-605: Improved flush method using new helper abstractions.The updated flush method leverages the new
emit_top_level_content_slicehelper with appropriate parameters for final content emission, ensuring consistent formatting.

💡 Verification agent
🧩 Analysis chain
Complex newline handling logic requires careful testing.
The incremental content emission methods contain intricate newline normalization logic that could be prone to edge cases. The emit_top_level_content_slice method handles multiple formatting scenarios with leading/trailing newline stripping and conditional newline addition.
Consider simplifying the newline handling logic or adding comprehensive unit tests to verify correct behavior across all scenarios:
- First emission with leading newline stripping
- Trailing newline normalization
- Empty content handling
- Mixed content scenarios

Add missing unit tests for newline handling in parser.rs
I couldn’t find any existing tests covering the complex newline‐normalization logic in emit_top_level_content_slice and its callers. Please add focused unit tests to cover:
- First emission behavior (leading newlines are stripped when
is_first = true). - Incremental emissions without stripping (
is_first = false,trim_trailing = false). - Flush behavior (both leading/trailing newlines trimmed, one trailing newline ensured).
- Empty or all-whitespace slices (no events emitted).
- Mixed content cases (content without trailing newline, with multiple leading/trailing newlines).
Key locations to target:
emit_top_level_content_slice(around lines 336–374 insrc/pipelines/text_generation_pipeline/parser.rs)- Calls in
emit_incremental_top_level_content(around lines 380–395) and in the flush logic (around lines 598–605)
Adding these tests will help guard against subtle edge cases in streaming output.
🤖 Prompt for AI Agents
In src/pipelines/text_generation_pipeline/parser.rs around lines 336 to 374 and
380 to 395, add unit tests for the emit_top_level_content_slice function and its
callers to cover newline normalization logic. Specifically, create tests for
first emission behavior where leading newlines are stripped (is_first = true),
incremental emissions without stripping (is_first = false, trim_trailing =
false), flush behavior with trimming and ensuring one trailing newline, empty or
all-whitespace slices producing no events, and mixed content cases with various
newline patterns. Also include tests for emit_incremental_top_level_content to
verify correct slicing and event emission. These tests should validate the
handling of newlines and event generation to prevent regressions in streaming
output formatting.
Refactor codebase to reduce duplication and complexity in pipeline builders, model layers, and XML parser.
This PR addresses high-severity code duplication and complexity issues identified in a recent scan, leading to a more maintainable and readable codebase by consolidating common patterns and simplifying complex logic.
