FSFS size limits?
Before I start off on converting a 24 gig BDB repository to a svn
1.2.1 fsfs repository, I was wondering if there are any file size
limits I need to know about? Googling seems to indicate there may be
a 2 GB limit for individual revisions, but upgrading to a newer APR
may fix that. Is that correct?
Thanks,
Dave

That is correct. If you do see a problem with that setup and large
files, we'd love to hear about it.

So, you are saying that if I build with APR-1.0 or later (configured
for large files), svnserve and fsfs should not have any problems with
individual revision files being larger than 2 GB?

That's a bit too simple. Yes, APR 0.9.x does have issues with largefile
support, and whether or not those issues apply in your case depends on
how your APR was compiled. APR-1.0 and later fixes those problems, IIRC.
Apart from that, yes, in FSFS these problems should only show up if an
indivitual revision file is larger than 2GB.

Look up the filesize limitations of the filesystem you're using, then you know
the limits of the FSFS repository :-) If your filesystem has no 2GB limit
then FSFS hasn't either, AFAIK.
C'ya,
