Special Character Inconsistencies
Hi all,
I have come across what appear to be inconsistencies with the handling
of special characters (ie '?') in filenames for URL-based renames &
deletes.
Examples:
> svn list svn://localhost/rename_test
alpha.txt
> svn rename svn://localhost/rename_test/alpha.txt
svn://localhost/rename_test/alpha?.txt
svn: URL 'svn://localhost/rename_test/alpha?.txt' is not properly
URI-encoded
This is an expected error. So, use the percentage notation:
> svn rename svn://localhost/rename_test/alpha.txt
svn://localhost/rename_test/alpha?.txt
Committed revision X.
> svn list svn://localhost/rename_test
alpha?.txt
It appears the rename has worked. But, we cannot rename the file back:
>svn rename svn://localhost/rename_Test/alpha%3F.txt
svn://localhost/rename_Test/alpha.txt --message ""
svn: Can't open file 'D://svnrepos/rename_Test/alpha?.txt/format':
The filename,
directory name, or volume label syntax is incorrect.
I get the same errors if I attempt to move the file to a different
location.
> svn delete svn://localhost/rename_Test/alpha%3F.txt --message ""
Committed revision 6.
Now, I'm not sure where the problem lies. Should these names even be
allowed? If so, then the rename obviously needs to be fixed.
Cheers,
Daniel B.

Yeah, sorry. I noticed that (for the svn:// protocol on Windows,
anyway), the repository name can be any case, but the path within the
repository needs to be case senstiive.
Ie
svn://localhost/RENAME_TEST/trunk
svn://localhost/Rename_Test/trunk
svn://localhost/rename_test/trunk
all work, but:
Svn://localhost/rename_test/TRUNK
will not.

Here you use "rename_test".

Here you use "rename_Test".
URLs are supposed to be case-sensitive, so you should use the correct
case.

I totally agree. I haven't hit this problem in the wild, yet, I just
came across it whilst trying to replicate the issue on the dev@ list
with the SVN repository (the ?WHAT?.txt file problem).
I think the problem arises because the server (not the client) is on
windows. So even if a *NIX client did the URL-only delete statement, the
same error would appear.
As I said, not something that we have seen actually happen, it was
purely a test case, and thought I would raise it.

Daniel B.

Oh yes, sorry, I should have guessed that from "Can't open file 'D://
svnrepos/rename_Test/alpha?.txt/format':"

It does seem strange, but since you're on Windows, you shouldn't be
using filenames that are incompatible with Windows. You should
install a pre-commit hook preventing such commits. I don't know of
such a script, but given the number of Windows users out there, I'd
think this is a common problem, and if you write one (Python seems to
be the language of choice for hook scripts at the moment), you should
contribute it so it can live with the other contributed hook scripts:

Apologies, yes, that is what I meant. Copied the wrong line from the

I'll give it a go on the file:// protocol, but I'm guessing I'll have
the same issue.

Subversion 1.5.2 on WinXP SP3. Haven't got a non-windows box to test on.
WinXP doesn't like having '?' in the filenames, but it seems strange
that SVN is including the filename part of the URL when trying to access
the internal repository structure.

I'm using Subversion 1.5.2 on an Intel Mac running Mac OS X 10.4.11.
What about you?
