Fix: - hunksOverlap() now checks filePath before checking line ranges - Sort hunks by filePath first, then line number - Added test case to prevent regression Test: 'does not combine hunks from different files' - Creates hunks from file1.ts and file2.ts - Verifies they stay separate even with overlapping line ranges - All 20 tests pass This ensures combined hunks only contain content from a single file. --- src/utils/review/combineHunks.test.ts | 42 +++++++++++++++++++++++++++ src/utils/review/combineHunks.ts | 20 +++++++++++-- 2 files changed, 59 insertions(+), 3 deletions(-) diff --git a/src/utils/review/combineHunks.test.ts b/src/utils/review/combineHunks.test.ts index 163f4aaa4..cddf8c9bf 100644 --- a/src/utils/review/combineHunks.test.ts +++ b/src/utils/review/combineHunks.test.ts @@ -203,3 +203,45 @@ describe("combineOverlappingHunks", () => { expect(result[0].combinedId).toBe("hunk-1+hunk-2"); }); }); + + test("does not combine hunks from different files", () => { + const hunks: HunkWithExpansion[] = [ + { + hunk: { + id: "hunk-1", + oldStart: 10, + oldLines: 5, + newStart: 10, + newLines: 5, + content: "test", + filePath: "file1.ts", + changeType: "modified", + header: "@@ -10,5 +10,5 @@", + }, + hunkId: "hunk-1", + expansion: { up: 0, down: 30 }, // Expands to line 44 + }, + { + hunk: { + id: "hunk-2", + oldStart: 40, + oldLines: 5, + newStart: 40, + newLines: 5, + content: "test", + filePath: "file2.ts", // DIFFERENT FILE + changeType: "modified", + header: "@@ -40,5 +40,5 @@", + }, + hunkId: "hunk-2", + expansion: { up: 0, down: 0 }, + }, + ]; + + const result = combineOverlappingHunks(hunks); + + // Should keep hunks separate because they're from different files + expect(result).toHaveLength(2); + expect(result[0].sourceHunks[0].hunk.filePath).toBe("file1.ts"); + expect(result[1].sourceHunks[0].hunk.filePath).toBe("file2.ts"); + }); diff --git a/src/utils/review/combineHunks.ts b/src/utils/review/combineHunks.ts index bfb21e15e..23c14995a 100644 --- a/src/utils/review/combineHunks.ts +++ b/src/utils/review/combineHunks.ts @@ -43,11 +43,19 @@ function getEffectiveRange( /** * Check if two hunks overlap based on their expanded ranges + * Only hunks from the same file can overlap */ function hunksOverlap( + hunk1: HunkWithExpansion, + hunk2: HunkWithExpansion, range1: { start: number; end: number }, range2: { start: number; end: number } ): boolean { + // Different files cannot overlap + if (hunk1.hunk.filePath !== hunk2.hunk.filePath) { + return false; + } + // Check if ranges overlap or are adjacent (within 3 lines) // Adjacent hunks should be combined for cleaner display const gap = range2.start - range1.end; @@ -122,8 +130,13 @@ export function combineOverlappingHunks(hunks: HunkWithExpansion[]): CombinedHun return []; } - // Sort by starting line number - const sorted = [...hunks].sort((a, b) => a.hunk.oldStart - b.hunk.oldStart); + // Sort by file path first, then by starting line number + // This ensures we process files separately + const sorted = [...hunks].sort((a, b) => { + const fileCompare = a.hunk.filePath.localeCompare(b.hunk.filePath); + if (fileCompare !== 0) return fileCompare; + return a.hunk.oldStart - b.hunk.oldStart; + }); const result: CombinedHunk[] = []; let currentGroup: HunkWithExpansion[] = [sorted[0]]; @@ -133,7 +146,8 @@ export function combineOverlappingHunks(hunks: HunkWithExpansion[]): CombinedHun const current = sorted[i]; const currentHunkRange = getEffectiveRange(current.hunk, current.expansion); - if (hunksOverlap(currentRange, currentHunkRange)) { + // Pass the hunk objects to check file path matching + if (hunksOverlap(currentGroup[0], current, currentRange, currentHunkRange)) { // Overlaps - add to current group currentGroup.push(current); // Extend the range to include this hunk From 39597ac945ad7390551644d8995bbb24a238a6e6 Mon Sep 17 00:00:00 2001 From: Ammar Date: Fri, 24 Oct 2025 22:24:22 -0500 Subject: [PATCH 16/18] =?UTF-8?q?=F0=9F=A4=96=20Improve=20EOF=20detection?= =?UTF-8?q?=20to=20handle=20empty=20expansion?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Better EOF detection after user clicks expand: - Detect empty/no content: hunk was already at EOF - Detect partial content: got fewer lines than requested - Use optional chain for cleaner code Behavior: - User clicks expand down on hunk at EOF - readFileLines returns null or empty content - EOF marker appears immediately after click - No expensive probing on mount (performance) This is the best we can do without file length metadata.
