Ahh good point, that is missing. Can you open a Jira issue? Thanks.

I'm more interested in reopen(IndexCommit) so I could have full
benefits of LUCENE-1483 (faster open, warm caches, less GC and so on)
but on specific commit point.
I'm not sure it's possible in current trunk, and if we have
open(IndexCommit) & company, maybe we should also have similar set of
methods for reopen?

What about opening IndexReader/Searcher on certain commit point?
Will it be implemented in 2.9?
The use-case is similar to the one Michael Busch described, only I
would like to open (or reopen) a searcher on specific commit point.

Actually I personally don't need Lucene to be "write once". The
reason
why
I started this thread about the segments.gen file was that in our
project we
sometimes need to rollback to a previous commit-point (using
Lucene
2.4.0)
that we keep around with the SnapshotDeletionPolicy. To get rid
of the
newest commit-point we simply delete the most recent segments
file. But
then
we also have to delete the segments.gen file, otherwise Lucene
will read
the
generation from it and try to find the segments file we deleted.
Then
Lucene
will recreate the segments.gen file. This just made me think
that this
is
not very clean (deleting and recreating the segments.gen)
especially
because
we use a local FS and don't even need the .gen file.
Ahh... OK. In trunk/2.9, you can explicitly open an IndexWriter
on a
prior
commit point, which will take care of the gen file for you.
