From be07978495ee356a5924fde44ad5bf64276fe2d1 Mon Sep 17 00:00:00 2001 From: Simon Garcia Date: Tue, 23 Dec 2025 04:41:13 +0100 Subject: [PATCH 1/5] Optimize trace commands with HashMap and remove dead code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace O(n) linear searches with O(1) HashMap lookups in trace and reverse_trace commands. Remove redundant DeduplicationFilter that was duplicating HashMap functionality. Performance improvements: - trace.rs: Use HashMap for both dedup checks and parent lookups (O(nĀ²) ā†’ O(n)) - reverse_trace.rs: Remove DeduplicationFilter, reduce allocations by 50% - dedup.rs: Delete unused DeduplicationFilter struct All 492 tests passing, zero warnings. --- .gitignore | 1 + CLAUDE.md | 2 +- cli/src/commands/reverse_trace/execute.rs | 72 ++++++++++++----------- cli/src/commands/trace/execute.rs | 46 +++++++-------- cli/src/dedup.rs | 47 +-------------- docs/NEW_COMMANDS.md | 11 ++-- 6 files changed, 71 insertions(+), 108 deletions(-) diff --git a/.gitignore b/.gitignore index 1bcc7a0..82e4c59 100644 --- a/.gitignore +++ b/.gitignore @@ -24,6 +24,7 @@ cozo.sqlite /phoenix_call_graph.json INPUT_FORMAT.md docs/tickets +/tickets/ .claude scratch /AGENTS.md diff --git a/CLAUDE.md b/CLAUDE.md index 1fdd3a9..30eef68 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -60,7 +60,7 @@ This is a Rust CLI tool for querying call graph data stored in a CozoDB SQLite d - `commands/mod.rs` - `Command` enum, `Execute` trait, `CommonArgs`, dispatch via enum_dispatch - `commands//` - Individual command modules (27 commands, directory structure) - `output.rs` - `OutputFormat` enum, `Outputable` and `TableFormatter` traits -- `dedup.rs` - Deduplication utilities (`sort_and_deduplicate`, `DeduplicationFilter`) +- `dedup.rs` - Deduplication utilities (`sort_and_deduplicate`, `deduplicate_retain`) - `utils.rs` - Presentation helpers (`group_by_module`, `convert_to_module_groups`, `format_type_definition`) - `test_macros.rs` - Declarative test macros for CLI, execute, and output tests diff --git a/cli/src/commands/reverse_trace/execute.rs b/cli/src/commands/reverse_trace/execute.rs index aa96d56..21bec8d 100644 --- a/cli/src/commands/reverse_trace/execute.rs +++ b/cli/src/commands/reverse_trace/execute.rs @@ -28,8 +28,6 @@ fn build_reverse_trace_result( // Process depth 1 (direct callers of target function) if let Some(depth1_steps) = by_depth.get(&1) { - let mut filter = crate::dedup::DeduplicationFilter::new();

charset=UTF-8 Content-Transfer-Encoding: 8bit BREAKING CHANGE: Replace substring matching with exact matching in non-regex mode across all query modules. Users must now use regex mode (--regex flag) for substring matching (e.g., ".*pattern.*"). This addresses the critical regex validation issue where invalid regex patterns caused cryptic CozoDB errors instead of clear user feedback. Changes: Database Layer (db/): - Add validate_regex_pattern() and validate_regex_patterns() helpers in query_builders.rs with comprehensive tests - Export validation functions from lib.rs - Standardize pattern matching across 13 query modules: * Non-regex mode: str_includes() ā†’ exact match (==) * Regex mode: regex_matches() (unchanged) - Refactor all affected modules to use ConditionBuilder and OptionalConditionBuilder for consistency - Add validation to all modules using regex patterns Affected modules: - accepts.rs, returns.rs, types.rs, specs.rs - struct_usage.rs (special OR condition handling) - complexity.rs, large_functions.rs, duplicates.rs - many_clauses.rs, unused.rs - hotspots.rs (4 functions refactored) - search.rs, trace.rs CLI Layer (cli/): - Update 9 failing tests to use regex mode for substring matching - Add 7 new tests verifying exact match behavior: * search: module exact match, function exact match, reject partials * struct_usage: type exact match, reject partials * unused: module exact match, reject partials Test Results: - All 586 tests passing (516 CLI + 70 DB) - Database tests: 70 passed - CLI tests: 516 passed (up from 509) User Impact: - Substring searches now require regex mode: --regex ".*pattern.*" - Invalid regex patterns now show clear error messages instead of cryptic database errors - Exact matching provides more predictable behavior Complete ConditionBuilder refactoring and document validation strategy Refactors the remaining query modules to use ConditionBuilder consistently, and adds comprehensive documentation explaining our regex validation approach. Changes: - Refactor search.rs to use ConditionBuilder (2 occurrences) - Refactor location.rs to use ConditionBuilder + OptionalConditionBuilder - Refactor file.rs to use ConditionBuilder (+ add missing validation) - Refactor structs.rs to use ConditionBuilder (+ add missing validation) - Add module-level docs to query_builders.rs explaining: * Same regex engine as CozoDB (regex = "1.10.4") * Double compilation is intentional for better UX * Performance cost (~1ms) is acceptable tradeoff Result: 19 out of 20 core query modules now use builders consistently. Only exception: struct_usage.rs (needs OR support, issue #3 in review doc). Impact: - Removed ~25 lines of duplicated if/else pattern matching code - Added missing regex validation to 2 modules (security improvement) - Single source of truth for exact vs regex matching logic - Improved maintainability and consistency --- cli/src/commands/search/execute_tests.rs | 140 ++++++++++- .../commands/struct_usage/execute_tests.rs | 67 ++++- cli/src/commands/unused/execute_tests.rs | 46 +++- db/src/lib.rs | 2 +- db/src/queries/accepts.rs | 24 +- db/src/queries/calls.rs | 4 +- db/src/queries/complexity.rs | 16 +- db/src/queries/duplicates.rs | 16 +- db/src/queries/file.rs | 11 +- db/src/queries/function.rs | 4 +- db/src/queries/hotspots.rs | 64 ++--- db/src/queries/large_functions.rs | 16 +- db/src/queries/location.rs | 19 +- db/src/queries/many_clauses.rs | 16 +- db/src/queries/returns.rs | 24 +- db/src/queries/search.rs | 90 ++++++- db/src/queries/specs.rs | 37 ++- db/src/queries/struct_usage.rs | 24 +- db/src/queries/structs.rs | 9 +- db/src/queries/trace.rs | 4 +- db/src/queries/types.rs | 37 ++- db/src/queries/unused.rs | 16 +- db/src/query_builders.rs | 231 ++++++++++++++++++ 23 files changed, 722 insertions(+), 195 deletions(-) diff --git a/cli/src/commands/search/execute_tests.rs b/cli/src/commands/search/execute_tests.rs index 2bb5361..abf6391 100644 --- a/cli/src/commands/search/execute_tests.rs +++ b/cli/src/commands/search/execute_tests.rs @@ -21,11 +21,11 @@ mod tests { test_name: test_search_modules_all, fixture: populated_db, cmd: SearchCmd { - pattern: "MyApp".to_string(), + pattern: ".*MyApp.*".to_string(), // Use regex for substring matching kind: SearchKind::Modules, common: CommonArgs { project: "test_project".to_string(), - regex: false, + regex: true, limit: 100, }, }, @@ -40,11 +40,11 @@ mod tests { test_name: test_search_functions_all, fixture: populated_db, cmd: SearchCmd { - pattern: "user".to_string(), + pattern: ".*user.*".to_string(), // Use regex for substring matching kind: SearchKind::Functions, common: CommonArgs { project: "test_project".to_string(), - regex: false, + regex: true, limit: 100, }, }, @@ -59,11 +59,11 @@ mod tests { test_name: test_search_functions_specific, fixture: populated_db, cmd: SearchCmd { - pattern: "get".to_string(), + pattern: ".*get.*".to_string(), // Use regex for substring matching kind: SearchKind::Functions, common: CommonArgs { project: "test_project".to_string(), - regex: false, + regex: true, limit: 100, }, }, @@ -113,6 +113,65 @@ mod tests { }, } + // Exact module match + crate::execute_test! { + test_name: test_search_modules_exact_match, + fixture: populated_db, + cmd: SearchCmd { + pattern: "MyApp.Accounts".to_string(), + kind: SearchKind::Modules, + common: CommonArgs { + project: "test_project".to_string(), + regex: false, + limit: 100, + }, + }, + assertions: |result| { + assert_eq!(result.modules.len(), 1);
