MULTIDIMENSIONAL SPATIAL SEARCHING FOR IDENTIFYING DUPLICATE CRASH DUMPS

摘要

A method of identifying duplicate crash dumps in a computer system may include receiving a first crash dump caused by an application crash, extracting a first function signature of a function that caused the first crash dump, and searching a datastore of crash dumps for function signatures that substantially match the first function signature. The searching may include performing an approximate string-match between each of the function signatures the first function signature and performing an exact string match between each of the function signatures and the first function signature. The searching may also include combining weighted results of the approximate string-match with weighted results of the exact string match to generate match scores for each of the function signatures, and identifying the function signatures that substantially match the first function signature based on the match scores.

1. A method of identifying duplicate crash dumps in a computer system, the method comprising:
receiving a first crash dump caused by an application crash; extracting, from the first crash dump, a first function signature of a function that caused the first crash dump; searching a datastore of crash dumps for function signatures that substantially match the first function signature, wherein the searching comprises:
performing an approximate string-match between each of the function signatures and the first function signature;performing an exact string match between each of the function signatures and the first function signature;combining weighted results of the approximate string-match with weighted results of the exact string match to generate match scores for each of the function signatures; andidentifying the function signatures that substantially match the first function signature based on the match scores.
