摘要
Utilizing diffgrams for trace indexing and replay. A subset of instructions of a trace, beginning with a first instruction and ending with a second instruction, are replayed to obtain state of one or more named resources. Based on replaying the subset of instructions, a diffgram is generated, which is structured such that addition of the diffgram at the first instruction brings the one or more named resources to the second state, and subtraction of the diffgram at the second instruction brings the one or more named resource to the first state. A pat of reaching a target instruction, the diffgram is later added at the first instruction to restore the second state at the second instruction, or subtracted at the second instruction to restore the first state of the first instruction.
