  "message": "[PDFium] Prevent infinite loop in AGG with degenerate dash patterns\n\nWhen rendering paths with extremely small dash patterns (e.g.,\n[0.000015, 0.000015]), the AGG backend enters a near-infinite loop\nattempting to generate millions of dash segments. This causes the\nrenderer process to hang indefinitely.\n\nThis CL mitigates the issue by detecting degenerate dash patterns in\n`RasterizeStroke()`. If the total length of a dash cycle is less than a\nsafety threshold (0.1f), the dash pattern is ignored, and the path is\nrendered as a solid line.\n\nNote: AGG and Skia render this case differently because Skia\u0027s stroke\npath implementation likely has built-in robustness checks or different\nprecision handling for extremely small dash segments that prevent\ninfinite loops, whereas AGG requires this explicit safety threshold to\navoid hanging.\n\nAdded regression test: bug_467170761.in\n\nBug: 467170761\nChange-Id: I7dbc20945f46f687e7e8b26c0538ffb371a95f00\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/139210\nReviewed-by: Lei Zhang \u003cthestig@chromium.org\u003e\nReviewed-by: Andy Phan \u003candyphan@chromium.org\u003e\nCommit-Queue: Lei Zhang \u003cthestig@chromium.org\u003e\n",
