Remove "synchonized" from FuzzyTermEnum#similarity(final String target)
-----------------------------------------------------------------------
Key: LUCENE-2258
URL: https://issues.apache.org/jira/browse/LUCENE-2258
Project: Lucene - Java
Issue Type: Improvement
Components: Search
Reporter: Uwe Schindler
Assignee: Uwe Schindler
Priority: Trivial
Fix For: 2.9.2, Flex Branch, 3.0.1, 3.1
The similarity method in FuzzyTermEnum is synchronized which is stupid because
of:
- TermEnums are the iterator pattern and so are single-thread per definition
- The method is private, so nobody could ever create a fake FuzzyTermEnum just
to have this method and use it multithreaded.
- The method is not static and has no static fields - so instances do not
affect each other
The root of this comes from LUCENE-296, but was never reviewd and simply
committed. The argument for making it synchronized is wrong.
