I got another idea which can be related to information from the section
“Case Study: Inconsistent Error Checks” in your document “WYSIWIB:
A Declarative Approach to Finding API Protocols and Bugs in Linux Code”.
A key aspect is the knowledge about failure predicates for functions
from programming interfaces.
How do you think about to improve the knowledge by the means of advanced
source code analysis?
I got the impression that such analysis attempts can become especially
challenging if data processing resources might occasionally be too limited
for a growing code base like Linux software.
Would you like to display statistics around the distribution of condition
checks after function calls (with help of the semantic patch language)?
Regards,
Markus
