I went through the entire repo, committing an empty random folder and incrementing the properties that determined the next rev to sync.  There are two sets of revs that seem to trigger the unknown error.  The first set included a directory that ended with characters identified by Tortoise as %E2%96%80.  As I was unable to rename this directory from Tortoise, I assumed that this was the issue and started looking into how I could clean the data.  I think I found a way, unfortunately, I don't find the same kind of 'extra' characters in the second second of revs.

Does anyone have *any* experience that is even remotely similar to this? *at all* ?

I'm literally sitting on the migration to the SVN 1.5.6 because I'd like to make sure the data is as clean as it can be... ... and because I want to know how to prevent svnsync from just failing quietly from similar user interaction in the future...

... please help...

Thanks!

I saw that thread.  I don't believe that is the case, here.  I am using an ID with full access, everywhere, and there are only two groups of revs where I encounter this issue, within the same 'sphere' of a single permissions directive.

Additionally, I was able to get svn-sync working again, using the following means:

1. hotcopying the original repo (for transfer from one server to another)
2. unpacking the hotcopy into its own repo
3. dumping the hotcopied repo into a dump file
4. loading the dump file into a newly created repo

And then svnsync against the newly loaded repo works without errors.

Note: The 'obvious' change in what was mentioned above (for me) is that the svnsync operation that works is using only 1.5.6 and repos touched by 1.5.6 tools.  There could be a number of other things that could be happening, in the hotcopy, the dump, or the load...

The question that I need to ask now is:
Are there any "gotcha's" with the way I was able to produce a working repo that could be replicated?

I have once helped someone with a 'Path ... not present' message on this list,
and the cause was access permissions for svnsync.
