Parents and children of check-in [b92d31a9]

Fix VDBE branch accounting on comparison operators. check-in: b287520c user: drh tags: trunk
Enhance the Win32 VFS I/O retry logic. check-in: adba783c user: mistachkin tags: winIoRetry
Add VdbeCoverage() and VdbeCoverageIf() macros for improved VDBE coverage testing. check-in: b92d31a9 user: drh tags: trunk
Improvements to "NOT IN (SELECT ...)" processing. Only test for NULL values on the RHS on the first iteration, then remember the result. There has been logic to do this for year, but it didn't work right and ended up repeating the NULL test on every iteration. This inefficiency was found using the VDBE coverage testing tools. check-in: 915f6f1c user: drh tags: trunk
