Description Ondrej Holy 2017-09-13 08:03:53 UTC

Description of problem:
Write opertations on webdav always fail with "500 Internal Server Error", read works correctly. See output from error_log:
[Wed Sep 13 09:44:07.105979 2017] [dav_fs:crit] [pid 16161:tid 139961240123136] (20019)DSO load failed: AH00576: The DBM driver could not be loaded
[Wed Sep 13 09:44:07.105997 2017] [dav:error] [pid 16161:tid 139961240123136] [client 127.0.0.1:43752] The locks could not be queried for verification against a possible "If:" header.  [500, #0]

Version-Release number of selected component (if applicable):
httpd-2.4.27-6.fc27.x86_64

How reproducible:
Always when trying to put/rm/edit/copy on webdav using cadaver, ls/cat works correctly.

Steps to Reproduce:
1. Configure webdav e.g. using the following in httpd.conf:
DAVLockDB DAVLock
Alias /dav /var/www/dav
<Location /dav>
  Dav On
</Location>
2. mkdir /var/www/dav
3. sudo service httpd restart
4. cadaver http://localhost/dav
5. dav:/dav/> put FILE

Actual results:
500 Internal Server Error

Expected results:
FILE is copied into /var/www/dav/FILE without failure

Additional info:
The same problem happens also with gvfsd-dav, so I suppose that it is httpd bug...

Comment 1 Joe Orton 2017-09-13 08:18:24 UTC

If you install apr-util-bdb does this go away?

Comment 2 Ondrej Holy 2017-09-13 08:48:00 UTC

Ok, the "DSO load failed: AH00576: The DBM driver could not be loaded" disappears from logs with apr-util-bdb, but still get "500 Internal Server Error" and see the following:

Comment 3 Michael J Gruber 2017-11-21 16:24:21 UTC

For the record:

The HTTPD-related test t5540 in the git test suite suddenly failed when I switched to F27 from F26.

Installing apr-util-bdb solved this issue (after quite some time of searching for other solutions...). Has this been split off in F27's package when it wasn't in F26? Lot's of surprise failures to expect...

Comment 4 David L. Crow 2017-12-20 00:54:36 UTC

I installed apr-util-bdb in Fedora 27 and my DAV issues have gone away.  All is working again.

Comment 5 Martijn Ras 2018-01-02 10:54:47 UTC

I ran into this problem as well, not just with the DavLockDB but also with the AuthDBMUserFile.

After installing apr-util-bdb i got the same errors as reported in comment 2.

After a lot of trial and error i got everything working again.
It appears the default DBM type has changed from 'SDBM' to something else.

1) Replacing 'AuthDBMType default' with "AuthDBMType SDBM" fixed the problems with the AuthDBMUserFile.

2) Removing the old DavLockDB files fixed the problems with the DavLockDB.

Comment 6 Martijn Ras 2018-01-02 12:00:16 UTC

I think apr-util-bdb should be set as dependency in httpd.

Comment 7 Paul Lambert 2018-01-11 20:19:16 UTC

Installing apr-utl-bdb after upgrading to fc27 from fc26 has resolved the file uploading errors that resulted in upload failure.  After installing this AND rebooting all is working as expected.

Comment 8 Armin Diehl 2018-02-20 21:15:30 UTC

i had the same problem and searched for hours.
Installing apr-utl-bdb fixed it (even without restarting http)

Would be nice if this problem can be fixed to prevent others from searching for hours as well.

I don't think this problem will be solved by the fix as committed, dnf builddep seems to ignore this Recommends. See the workaround in git sources, https://src.fedoraproject.org/rpms/git/blob/master/f/git.spec#_172
