Do you want to post it on the user list? It might also be good to put
it up on the main website.

that to java-user tomorrow and see. Hey, how about some bets? I'll put a $10
for a beer on 1.5.
Wow, $10 for a beer? That must be some pretty good beer. Either that
or you live in New York City and that is a cheap beer! Anyway, I am
betting it is 1.5 as well. Maybe we can get together at ApacheCon or
something for one...

Subject: Re: Java 1.5 was [jira] Updated: (LUCENE-600) ParallelWriter companion
to ParallelReader
In addition to performance, productivity and functionality benefits, my
main argument for 1.5 is that it is used by the vast majority of lucene
community members.
I am not so sure about this. Perhaps we should take a poll on the user
list? Not even sure how that would be managed or counted, but...
Everything I write is in 1.5 and I don't have time
to backport. I have a significant body of code from which to extract
and contribute patches that others would likely find useful. How many
others are in a similar position?
I definitely would prefer to make future contributions in 1.5 (even the
patch we just contributed (issue 545) could have been better given 1.5,
but it is fine with 1.4 as well). I tend to think if people don't want
the new functionality or if it breaks their app. then they need not
upgrade, or they can contribute patches against the branches for prior
releases and we can support that as needed. To me, this is what major
releases are about. I know that when a major release comes out that I
should expect library changes that may break my code. If I don't want
that pain, then I don't upgrade.
On the side, not leaving valued community members behind is important.
I think the pmc / committers just need to make a decision which will
impact one group or the other.

Well, we have our first Java 1.5 patch... Now that we have had a week
or two to digest the comments, do we want to reopen the discussion?

Chuck Williams updated LUCENE-600:
----------------------------------
Attachment: ParallelWriter.patch
Patch to create and integrate ParallelWriter, Writable and
TestParallelWriter -- also modifies build to use java 1.5.
ParallelWriter companion to ParallelReader
------------------------------------------
Key: LUCENE-600
URL: http://issues.apache.org/jira/browse/LUCENE-600
Project: Lucene - Java
Type: Improvement
Components: Index
Versions: 2.1
Reporter: Chuck Williams
Attachments: ParallelWriter.patch
A new class ParallelWriter is provided that serves as a companion to
ParallelReader. ParallelWriter meets all of the doc-id
synchronization requirements of ParallelReader, subject to:
1. ParallelWriter.addDocument() is synchronized, which might
have an adverse effect on performance. The writes to the
sub-indexes are, however, done in parallel.
2. The application must ensure that the ParallelReader is never
reopened inside ParallelWriter.addDocument(), else it might find the
sub-indexes out of sync.
3. The application must deal with recovery from
ParallelWriter.addDocument() exceptions. Recovery must restore the
synchronization of doc-ids, e.g. by deleting any trailing
document(s) in one sub-index that were not successfully added to all
sub-indexes, and then optimizing all sub-indexes.
A new interface, Writable, is provided to abstract IndexWriter and
ParallelWriter. This is in the same spirit as the existing
Searchable and Fieldable classes.
This implementation uses java 1.5. The patch applies against
today's svn head. All tests pass, including the new
TestParallelWriter.
