Robert Muir commented on LUCENE-10579:
--------------------------------------
There's all kinds of stuff being printed, but this gives you an idea of what
the 28.4MB looks like.
So I'm not surprised if this smoketester check fails here and there, its such a
noisy channel. All it takes is something like MockRandomMergePolicy or some
other component logging from another thread to prevent that multiline regexp
from doing the right thing?

> fix smoketester backwards-check to not parse stdout
> ---------------------------------------------------
>
> Key: LUCENE-10579
> URL: https://issues.apache.org/jira/browse/LUCENE-10579
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Robert Muir
> Priority: Major
> Attachments: backwards.log.gz
>
>
> The smoketester parses the output of TestBackwardsCompatibility -verbose
> looking for certain prints for each index release.
> But I think this is a noisier channel than you might expect. I added a hack
> to log the stuff its trying to parse... it is legit crazy. See attachment
> Let's rethink, maybe we should just examine the zip files?
