I forwarded the "SVNAllowBulkUpdates Off" question to the users@xxxxxxxxxxxxxxxxxxxxx

You mean "Unless bulk updates are enabled" and "without an
intervening
close_file", right?
The problem seems to be skelta mode although it may just be the
fact
that ra_serf has multiple connections outstanding and since
ra_neon only
ever has one it can't happen over ra_neon.
If the server disables bulk updates (SVNAllowBulkUpdates Off) all
clients are forced to use skelta mode, even ra_neon clients.
As Brane and I have pointed out, git-svn can instruct libsvn_* to
use
bulk updates regardless of the server version, by setting
SVN_CONFIG_OPTION_HTTP_BULK_UPDATES (new in 1.8).
If you have questions about that, though, please address them to
users@xxxxxxxxxxxxxxxxxxxxx (the proper list for API usage
questions),
not to me personally.
According to the table at
<http://subversion.apache.org/docs/release-notes/1.8.html#serf-skelta-default
>,
if the server sets SVNAllowBulkUpdates Off, the client will be
forced to use
skelta no matter what the client setting is.
Indeed, the server admin has the final say in which mode is actually
used. SVNAllowBulkUpdates Off is only advised if the server admin
wants a log line per accessed resource. I doubt it's used a lot, but
the option is there.
Is that table incorrect?
No, that table is correct.
Lieven
So the final say so on whether or not bulk updates are allowed is on
the server side which means git-svn really needs to handle skelta mode
on the client side properly when using ra-serf to guarantee
functionality with all subversion server configurations.
