Go Static: Contextualized Logging Statement Generation
CoRR(2024)
摘要
Logging practices have been extensively investigated to assist developers in
writing appropriate logging statements for documenting software behaviors.
Although numerous automatic logging approaches have been proposed, their
performance remains unsatisfactory due to the constraint of the single-method
input, without informative programming context outside the method.
Specifically, we identify three inherent limitations with single-method
context: limited static scope of logging statements, inconsistent logging
styles, and missing type information of logging variables. To tackle these
limitations, we propose SCLogger, the first contextualized logging statement
generation approach with inter-method static contexts. First, SCLogger extracts
inter-method contexts with static analysis to construct the contextualized
prompt for language models to generate a tentative logging statement. The
contextualized prompt consists of an extended static scope and sampled similar
methods, ordered by the chain-of-thought (COT) strategy. Second, SCLogger
refines the access of logging variables by formulating a new refinement prompt
for language models, which incorporates detailed type information of variables
in the tentative logging statement. The evaluation results show that SCLogger
surpasses the state-of-the-art approach by 8.7
32.1
score. Furthermore, SCLogger consistently boosts the performance of logging
statement generation across a range of large language models, thereby
showcasing the generalizability of this approach.
