-----------------------------------
Summary: Lucene41PostingsWriter.advance() doc scanning is buggy
Key: LUCENE-6014
URL: https://issues.apache.org/jira/browse/LUCENE-6014
Project: Lucene - Core
Issue Type: Bug
Reporter: Robert Muir
The "code duplication" here to optimize scanning to target after "possible
skipping" looks really buggy.
For example, it never checks to refill buffer in the loop if it gets exhausted.
But the code gives no indication about why its safe for it to make this
assumption.
If nobody understands why this optimization is allowed to make such a shortcut,
then please add a comment indicating why, with asserts tied to exact specific
constants in skipwriter (if applicable), otherwise i will remove the
optimization completely in 72 hours.
