Description

SVNAutoversioning applications like Microsoft Office and LibreOffice lock
documents with locks that expire:

$ svnadmin lslocks repo
Path: /A/f
UUID Token: opaquelocktoken:471bc389-d797-41d4-b963-995139d55cd2
Owner: pm
Created: 2014-04-03 22:23:45 +0100 (Thu, 03 Apr 2014)
Expires: 2014-04-03 22:26:45 +0100 (Thu, 03 Apr 2014)
Comment (1 line):
<ns0:owner xmlns:ns0="DAV:">http://ucb.openoffice.org</ns0:owner>

and then attempt to refresh such locks with a request like:

LOCK /obj/repo/A/f HTTP/1.1
Connection: TE\r
TE: trailers
Host: localhost:9630
If: (<opaquelocktoken:471bc389-d797-41d4-b963-995139d55cd2>)
Timeout: Second-180
Pragma: no-cache
Authorization: Basic cG06bXA=

These requests fail with 412 precondition failed:

[Thu Apr 03 22:26:15 2014] [error] [client 127.0.0.1] Could not LOCK
/obj/repo/A/f due to a failed precondition (e.g. other locks).  [412, #0]
[Thu Apr 03 22:26:15 2014] [error] [client 127.0.0.1] (2)No such file or
directory: The precondition(s) specified by the "If:" header did not match this
resource. At least one failure is because: a State-token was supplied, but it
was not found in the locks on this resource.  [412, #0]
