what causes "File exists: file not found"?
A college student is doing a project related to Subversion and has
decided to use my site as part of her research. Unfortunately this has
created a great many errors in my Apache log file. What causes these and
how do I fix them?
[Wed Aug 28 15:39:49 2002] [error] [client XX.XXX.XX.XX] (17)File
exists: file not found: revision `0', path `/benoit' [404, #160013]

Thanks a lot. Using the latest snapshots of Apache, APR and APR-util, it
finally all works fine on my Linux box!
I guess this also means that the Win32 version of Subversion is not
going to work without compiling the latest Apache/APR/APR-util or even
Subversion sources?

The 2.0.40 tarball doesn't work for Subversion. The error codes in APR
changed a little while ago, and those are not incorporated into 2.0.40.
Thus, you end up with a mismatch of error codes between Apache and
Subversion (since the latter is built against a newer APR).
In essence, Subversion requires Apache 2.0.41-dev or later (-dev means that
it is between .40 and .41). Subversion also requires APR 0.9.1-dev or later
(the CVS version).
We have not (yet) put these requirements into our buildcheck or
configuration process, but will shortly. Now that APR is actually getting
versioned, then we can start relying on using those numbers to specify
minimum requirements.
And yes: I know this is the exact cause of the problem because it frustrated

Ok, here goes:
I am using Apache 2.0.40, Subversion 0.14.2 (not self-compiled, just the
downloadable binary executable versions).
Creating a repository works. Accessing via file system works, too. For
example:
| E:\test_jh>svn list file:///E:/svndav/svnrepo
| test_jh/
|
(I had successfully imported test_jh/ before)
However, accessing the repository via HTTP fails:
| E:\test_jh>svn list http://capella/svn/svnrepo
| svn: Bad URL passed to RA layer
| svn: No part of path '/svn/svnrepo' was found in repository HEAD.
|
The respective apache log file snippet:
| [Wed Sep 04 15:18:21 2002] [error] [client x.x.x.x]Could not fetch
resource information. [500, #0]
| [Wed Sep 04 15:18:21 2002] [error] [client x.x.x.x] Could not open the
SVN filesystem at E:/svndav/svnrepo [500, #165005]
| [Wed Sep 04 15:18:21 2002] [error] [client x.x.x.x] Expected version
'1' of repository; found no version at all; is `E:/svndav/svnrepo' a
valid repository path? [500, #165005]
The respective httpd.conf snippet (running ok with mod_dav_svn):
| <Location /svn/svnrepo>
| DAV svn
| SVNPath E:/svndav/svnrepo
| </Location>
(I also tried /svndav/svnrepo, e:\svndav\svnrepo, e:\\svndav\\svnrepo...
for SVNPath)
Also, accessing the repository via browser
("http://x.x.x.x/svn/svnrepo") also yields:
| Expected version '1' of repository; found no version at all; is
`/svndav/svnrepo' a valid repository path?
Hope you can help,

That seems strange, hm.

Have you tried using the latest CVS versions of apache, apr, and
apr-util?

I get this error message too, but for me, it is not "non-fatal": It
happens upon the basic import. Importing through the filesystem works
fine, but importing over http fails with the above error message. Any
ideas why this happens?
I am trying to get Subversion to run on SuSE-Linux. I am using Apache
2.0.40 and Subversion 0.14.2. I also tried substituting the apr and
apr-util libraries of Apache with those of Subversion (as those seemed
newer), but to no avail. - I am by no means a linux expert,
unfortunately, so I don't know much about any magic library conflicts
that may happen...
I also tried to get it to run on Windows NT (same versions), but that
also still fails (different error messages).
I'd much like to work on something like a Java client for subversion,
but as of now, I'm just getting frustrated with installation issues.

Ew, error-reporting routines which gratuitously look at errno. A common
source of confusing error messages.

The errno was non-zero ("File exists"), so it got logged. The message that
was logged, however, was "file not found".
It seems that something needs to set that error to zero... Where? Dunno.

What does "File exists: file not found" mean anyway? :)
Apache: "I know it's here somewhere... Where did I put it?"

Not really, no. You asked for a resource, and it wasn't there. Simple as
that, so it logs the error.
That said, you could add a header like 'X-SVN-Existence-Probe: yes' into the
stream, have mod_dav_svn recognize that, and avoid logging most of the
errors. However, Apache itself is still going to log the 404.
[ hmm. maybe not... we could always get mod_dav to generate an error
response, which would include/exclude logging, but I'd rather not ]

I've been seeing these non-fatal errors in my logfile for a while
too. I think they have something to do with ra_dav_get_baseline_info
making all sorts of existence queries on different URLs; it's
perfectly fine for an existence check to come up empty, but the server
shouldn't log it as an error.
Is there any way to make mod_dav_svn recognize the difference between
an *unexpected* failure to find a resource, vs. an unimportant
existence check?
