Folks,
I used dump and load to debug the malformed node revision ID. Here are my
steps and what learned. Looks like the revs' file text: entry has a zero
instead of size. By just editing the size, verify worked. No other change
was required. The question is can we correct this ourselves without a dump and
load?
Thanks
Andy

svnadmin: E160062: Malformed node revision ID string
Can we edit the revs 'text:" entry instead of a dump a load?

Nice, great that dump+load fixes it. I don't think there is a quicker method.
It might be worth investigating why this happened to begin with. But I don't
really know where to start. One hypothesis is that this corruption is already
lingering there for years (until 1.9 it wouldn't have been noticed) ... perhaps
something outside of SVN manipulated the rev files years ago? Or perhaps there
was a bug once in SVN that caused this to happen (but the corruption remained
benign / unnoticed, until the stricter validation by 1.9). It's also possible
that the stricter validation by 1.9 contains a bug, and is too strict for some
cases (though in that case I would have expected more reports on this list).
Maybe you can make a more accurate hypothesis by investigating exactly what the
"Malformed node revision ID string"s looks like. Actually, danielsh just
improved that error message a few days ago, by adding the actual data to the
error message:
https://urldefense.proofpoint.com/v2/url?u=http-3A__svn.apache.org_viewvc-3Fview-3Drevision-26revision-3D1825846&d=DwIFaQ&c=LFYZ-o9_HUMeMTSQicvjIg&r=lHImfy5Z3mUV3q_wXtPXpg&m=H1vU79y-LZUNg2o-MTOUnApkEdSPmq6uvVWkpF1n-ZM&s=VcsP7Qwl3TAy_zSkzRZaG5vEBgC4alj__qhGeBQr_54&e=
So if you can build svn from source you might be able to perform a build from
the latest svn trunk, and run 'svnadmin verify' to get the more verbose error
message (be careful not to use your trunk svn build on production data without
creating a backup of course). Or alternatively you can try taking a look into
the rev files yourself, to find the "malformed node revision ID".
