Subject [jira] [Commented] (LUCENE-5850) Constants#LUCENE_MAIN_VERSION can have broken values
Date Mon, 28 Jul 2014 12:11:39 GMT


Robert Muir commented on LUCENE-5850:

The real bug here is not what simon describes... (although I think its confusing, and its
extra confusing there are "two versions"). 

It is not that 4.8.1 is good, actually 4.8.1 is the buggy one. Segments with 4.8.1 say they
were written with "4.8", which is broken.

Furthermore, code like Lucene45DocValuesProducer doing stuff like the below is also broken:

The main problem is caused by the overengineering of this shit: two different version values,
one of which is driven by a system property, and other confusion. Because of this its also
not tested. I realize this system property shit is supposed to be there to support "strange"
things like custom builds and maven snapshots, but its gotta die. Sorry, its broken for actual
lucene releases!

> Constants#LUCENE_MAIN_VERSION is set to the Lucene Main version and should not contain
minor versions. Well this is at least what I thought and to my knowledge what the comments
say too. Yet in for instance 4.3.1 and 4.5.1 we broke this such that the version from SegmentsInfo
can not be parsed with Version#parseLeniently. IMO we should really add an assertion that
this constant doesn't throw an error and / or make the smoketester catch this. to me this
is actually a index BWC break. Note that 4.8.1 doesn't have this problem...
